Description

The present invention relates to a concrete form for forming a wall or the like according to the preamble of claim 1. The invention also relates to a method for manufacturing a wall or the like according to the preamble of the invention. The invention also relates to claims which can be used in a method according to above, er ins šzTEKNIKENS STÄNDPUNKTHus with solid frame, for example of concrete, brick or lightweight tiles, are known to have many good properties such as good fire safety for example compared to Other houses have a wooden house, they last a long time and are not as maintenance-intensive. houses built with a solid frame are that they provide a good indoor climate with small temperature variations throughout the day and have good properties in terms of withstanding moisture and mold.

The most common methods used today to achieve a solid frame consist of masonry (lightweight clinker blocks, bricks, lightweight concrete blocks, etc.) or mounting prefabricated wall elements.

An advantage of building a house on site compared to using prefabricated elements is that it is easier to make special adjustments that depend on the special object, place for erecting the object, and so on. and that you avoid desk joints that are inevitable between prefabricated wall elements. One disadvantage, however, is that it requires a high degree of craftsmanship.

An advantage of using prefabricated elements is that it is very quick, often in just a few days, to get a tight housing, which makes it possible to work with installations and surface layers in protection against weather and wind.

As an alternative to masonry and prefabricated concrete houses, concrete can be cast on site. Concrete is a very malleable and flexible material, and xüxi construction of houses is the principle mold that becomes the boundary in terms of the construction project's flexibility and freedom of choice. Today, however, it is very unusual to cast something other than a base plate, and possibly basement walls in place. The reason for. this is “that molds and molding work are very expensive and especially in small projects these costs often amount to more than 50% of the total cost of the frame. The alternative areas available are traditional loose timber and finished, e.g. rented, large molds such as Dokaw, Peri.

Traditional loose timber form requires a high price per square meter.

For large form, the price per square meter is lower, especially in large construction projects where the same form of construction can be reused many times, large form is awkward and difficult to assemble; but the most suitable method of installation is often with the use of a construction crane. Another disadvantage is that after casting, insulation must be installed with some form of system.

Another alternative is to use insulated form blocks, so-called ICF. mold block stacked to a wall and filled with concrete. When the concrete has solidified Insulated Concrete Forms, Such as the cellular plastic form remains as insulation wall. This enables the rapid construction of concrete walls at a relatively low cost. However, a disadvantage has been found to be that, since the concrete is insulated on both sides, this is climatically disadvantageous with regard to the indoor climate, and the advantages of a solid frame which are achieved by building houses with some of them are not outweighed. Another disadvantage is that such a wall, neither on the inside nor on the outside, is ready to be provided with a surface layer. Cellulose on the inside of a frame can also increase the risk of fire. km fl ånThus, all ygg systems now suffer from disadvantages. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a single concrete form as initially indicated by which one or more of the above problems can be remedied.

Fig. 12 shows use according to Fig. 10 in DETAILED DESCRIPTION OF THE INVENTION Fig. 1 shows a concrete mold 100 according to the invention which comprises a first wall forming device 10 which here consists of a foam block 11 which is spontaneously in vertical direction, with groove 13 and spring 12, for to provide good stability when several foam blocks are placed on top of each other to form a wall. In other, the cellular plastic blocks in addition, or not shown, horizontally because even in the cellular plastic blocks need alternatively, be spontaneously horizontal joint increase the stability. According to other embodiments of the invention may not be spontaneous, or they may be shaped or spontaneous in other ways, whereby examples will be given below.

The concrete mold also comprises a second wall-forming device 20, which here consists of a mold plate 21, for example consisting of the known plywood board, or a sandwich-shaped product, the product Sonoboard, or some other type of material which is light, rigid and durable.

In addition, the forming rod 30 comprises which in a first outer end are provided with a fastening element 40 and in a second opposite end are provided with a locking device 50. The function of the forming rods 30 is to connect the first wall forming device 10 and the second wall forming device 20 to each other, preferably so that they are arranged parallel to, and in a certain way that a space x is formed. It should be clear from each other, however, that depending on the desired shape of the wall or the like to be cast, the distance may also, if desired, be tapered in the horizontal or vertical direction or assume any other desired shape. or several per foam block 11, example four, one of which is not mounted, the block 11 is shown in Fig. 1. In the example shown, the block 11 is provided with prepared slots designed to receive the fasteners 40 in the spring boundary. For mounting, the fasteners 40 are inserted into the prepared slots in the plastic block 11, substantially so that the respective forming rod 30 will extend perpendicular to one vertical plane of expansion of the first wall device. Thereafter, a plurality of molded plastic blocks 11 can be stacked on top of each other, as illustrated in Fig. 2. ... 4 The mold plate 21 is preferably provided on its one outer edge, here at the top, with grooves or recesses 22 intended to receive the mold stay 30. The mold rods 'outer_end years' are located in the grooves 22 when mounted, especially in such a way that a locking element 51 included in the locking device 50 is located. on the side of the mold plate 21 facing the foam block 11 and a holding element 52 and locking element 53 on the other side of the mold plate, so that the mold plate 21 is locked therebetween. The recesses 22 may have a size corresponding to the size (eg diameter) of the tie rod stay rod 31, which normally presupposes that the locking device must be removed before the forming plate; alternatively, the recesses can be larger so that the mold plate can be torn, the inner locking devices are removed and struts are cut if necessary.

Preferably, the wall is reinforced before the second wall forming device 20 is brought into place, i.e. after the fastening elements 30 (the mold struts) are arranged in the foam block 11.

Before reinforcement, any recesses for windows and doors, cables, etc. (not shown) should be fitted. Any electrical equipment, such as pipes, and ventilation equipment, which are to be molded into the wall, are suitably mounted after the wall has been reinforced. The mold plate 21 is arranged at the desired distance from the foam block 11 with the mold rod 30 through the locking device 50, where the mold plate is locked between the first holding element 51 and the the second holding element 52 by means of locking elements 53, and concrete is poured into the formed space between them.

Fig. 2 shows a number of cellular plastic blocks 11 stacked on top of each other which form a first wall-forming device 10 and a number-forming discs 21 arranged to form the second wall-forming device 20, which are connected by the forming rods 30. In mold plates mounted and locked with the mold struts and mold locks in an advantageous embodiment, cellular plastic blocks and / or in such a way that mutually spliced cellular blocks and / or mutual joints or mold plates are placed in one and the same plane in a row and / or a column are displaced in relation to joints between cellular plastic blocks and mold sheets' in an adjacent row or column for stability reasons.

Fig. 2 shows the concrete mold, but not reinforcement etc., before casting, whereby concrete is poured into the space between the first and second wall-forming devices 10,20. When the concrete has solidified, the locking device 50 is removed by first single locking element 53 being removed. Then, second retaining elements are removed and the mold discs 21 are torn. This gives a wall near a solid frame insulated by the foam blocks 11 and which has an inner side which only needs to be provided with the desired surface layer, e.g. putty and paint or wallpaper.

As discussed above, advantageous reinforcement may be made and relevant conduit installations for electricity, pipes, ventilation may be laid after the reinforcement but before the second wall forming device 20 is placed and temporarily locked at the mold stays 30 by means of the locking devices 50.

In particular, an advantageous scaffold according to the invention can be used in casting, which will be discussed with reference to Figs. 10-12 below. Of course, the invention is not limited to the use of this scaffold, but casting can of course be done in any way and with any suitable conventional scaffold.

SCWo-m (cureWhen the concrete has solidified, the locking device 50 can be easily removed from the locking soup, which will be discussed further below. The mold disc 21 or the mold discs can then be easily torn.

The invention provides a concrete form which forms a wall or a floor or other similar structure, which is moisture-proof, resistant to mold attack, fireproof, energy-efficient, and which is also very flexible. It is also easy to handle and minimizes both the number of heavy lifts and the weight of these, and more generally the amount of lifts.

In certain embodiments, the concrete mold according to the invention may comprise a first wall forming device and two second wall forming devices arranged on either side of the first wall forming device so that a sandwich wall can be cast. Thus, the tie rods via the respective fastening elements are attached to the first wall forming device and directed in the opposite direction. In this way, according to the construction consisting of casting, an insulating block (cellular plastic block) is obtained, surrounded by concrete on two sides.

An example of a part of a wall and a floor with reinforcement, but before casting is shown schematically in Fig. 7A, and in Fig. 7B the corresponding but also schematically also shown with electrical, ventilation and water ducts. The mold struts 30 can be designed on many different ways. Fig. 3 schematically shows a forming rod 30 according to the embodiment in Fig. Line comprising a forming rod rod 31 with at a first end arranged fastening element 40 which here consists of a square plate arranged perpendicular to the longitudinal extent of the rod rod 31, which consists of a rod or the like. In the example shown, the fastening element 40 has a square shape, but it can of course be of any shape as long as it extends at least vertically in a single-headed direction facing downwards Fig. 2) (for a wall, for example according to relative the tie rod 31. The fastening element or fastening plate 40 can also have a varying thickness, for example be thinner, have a continuously decreasing thickness in vertical direction downwards, possibly also upwards, to facilitate insertion into the first wall forming device 10. Insertion can take place in different ways, for example the fastening element can be inserted from above in solid cellular plastic or in prepared receiving spaces in vi 7e >> v 12 cellular plastic blocks, or between cellular plastic blocks, which will be discussed further below with reference to Figs. 6A, 6B.

At the opposite end of the tie rod 31 of the forming rod 30, a locking device 50 is arranged between the inner and outer (first and second) holding elements 51, 52, a forming plate 21 is temporarily arranged in the desired position and locked by means of locking element 53 which can be easily unlocked so that the locking device 50 and the mold plate 21 can be easily removed after casting, when the concrete has solidified. The locking device is pressed here so that it functions essentially as a wedge, and the end knob arranged on the strut rod 31 is passed through a hole while fitting size for passage, and the locking device is passed through a groove with a width such that the end knob cannot pass, only the strut rod fits and can be brought down into the track. A mold plate not shown in this Fig. Will then be wedged between the cone 56 and the locking device / spirit knob. Locking devices are further discussed with reference to Figs. 5A, 5B.

Figures 4A ~ 4C show different examples of tie rods where the tie rods are differently designed in that either the tie rod itself, the mounting plate and / or the locking device are designed in different ways.

It should be clear that in these figures a simplified locking device is shown; the embodiments may include any type of locking device. In the examples shown, it comprises a screw-on locking element which simultaneously forms second holding elements and a first holding element which is either fixedly arranged on the tie rod or which can be arranged at a suitable distance on the rod by means of a suitable locking mechanism e.g. threading and nuts and washers.

The mounting plate 40A in Fig. 4A is, like the mounting plate 40 in Fig. 1, essentially one. square plate, but whose thickness upwards and downwards in the vertical direction tapers so that the mounting plate 40 can be more easily insertable into a foam block, especially when inserted into solid foam, this is advantageous. In an exemplary embodiment not shown, vertical joints decrease. first. The thickness must be continuously introduced at the end to Then, however, always the narrowest Many variants for facilitating the introduction of examples in a foam block are possible, as well as for the contribution to good retention, which is an advantage considering that reinforcement and wiring are performed with inserted tie rods.

Fig. 4B shows a fastener 4OB consisting of a plate whose side is toothed, or also has a zig-zag pattern to facilitate insertion into a foam block; in particular if it is to be incorporated into solid material.

Fig. 4C shows a fastening element 4OC which is separate from the rod 31C rod 31C, and which can thus be fastened directly in the foam block by insertion into a gap provided therefor or directly in solid material but which has a hole 41C intended to receive a hook 32C on the rod rod 31C. The hole 41c is formed in a planar portion of the fastener which is intended to be arranged parallel to an upper surface of the foam block, and which is provided, here, with a comb-like element 44C which forms an angle of substantially 90 ° with the planar portion 42C (extending in same plane, or a plane parallel to the stay rod 3lC). The flat part may also be provided with a second flat part on the side facing away from the side where the tie rod is to be arranged and forming an angle of 90 ° with the first flat part 42C. However, this is not necessary. Instead of two substantially parallel cam elements, it can be only one, or more. If there are several, these may be provided in Fig. 4C, in order to increase the stability of the retention capacity in, for example, a single-cell plastic block so that the fastening element is even more securely held in place. 14 In general, for all types of fastening elements, it applies that they can be fixedly connected to the rod part of the forming rod (rod rod), or detachable therefrom. In particular, they can be formed in one piece therewith, which, however, does not apply to designs as in Fig. 4Catt they can, however, where precisely sought after, be detachable; of course also a plate as in Fig. 4C be fixedly connected to the place to be provided with a forming rod. the tie rod is a hook and the fastening element with a hole, the plate can of course be provided with a hook and the tie rod with a hole or the like. In addition, other equivalent mechanisms can of course be used which allow easy and safe assembly with a fastening element in place for example a foam block. Cam elements can of course be designed in other ways or be connected to, or in one piece with, a tie rod as in Figs. 4A, 4B.

Vaàwš _šåL) Fig. 5A shows a locking device 5OB arranged on a forming rod ÅÖ comprising a tie rod 311. Rod bar 311 any end knob. The locking device 50B, also called mold lock, may for example be of the known type Gekunå or of a similar type. It comprises a wedge-shaped or beveled locking element 53B where the wedge or the like is designed to be pressed into a receiving opening formed between a plate element 52B and 52B on the plate element 52B. here consists of a plate with a central hole 311, and the holder part 54B consists of a bent welded on the plate 52B a hole for arranged this plate element intended to receive the bar part part (stay bar) plate likewise with passage of the stay bar. The wedge-shaped locking element 54B can thus be folded down and lock the tie rod between the wedge and a side in the space formed. is not equipped with With a light stroke upwards on the narrow lower part of the wedge, this can be easily knocked out, so that the lock and mold plate can be easily removed after completed casting.

The part of the mold stay that protrudes from the mold can be tilted slightly, and broken off, and then broken at the level of the inside of the cone which is included in the locking device, e.g. 50A, which is on the tie rod; the cone can be pulled out and the cone-shaped hole that is formed can be filled again, which is advantageous e.g. in that no bushings are formed, e.g. for rust.Fig. 5B shows an alternative locking device 50 which substantially corresponds to the locking device shown in Fig. 3. The locking device comprises a one-piece pressed plate 52 which is provided with a groove for the tie rod 31 which. comprises a larger hole at one end of the ice groove, and a narrower part which, when the strut rod is inserted, the strut rod 31 arranged prevents one from passing on the end knob 53. The end knob is here welded to the end of the stay rod. According to an alternative, the end knob 53 can be unscrewed so that the lock releases, whereupon the rod can be moved upwards and the end knob can be carried out through the hole so that the lock can be released and the mold plate removed.

The mold lock can also preferably be wedge-shaped and with a slight stroke upwards on the narrow lower part this can be easily knocked out due to the wedge shape and when there is a distance of for example 1.5-2 cm the needle end knob and the mold plate, so that locks and the plate and mold plate easily can be removed after finished casting.

This mold lock is of a type similar to the known mold lock type KF ”. 16 Many other different variants of form locks can also be used, e.g.

Temposhalerm.

Fig. 6A shows an example of a first wall forming device 10 comprising a spontaneous foam block 11 with spring 12 and groove 13 and which is provided with a recess 14 intended to receive a fastening element 40 on a forming rod 30. method, Mounting plates on forming rods can be used this formed on different to be in different ways, either to be inserted into purpose-built, prepared openings; it places ~ in principle no requirement that the fastening element needs to be designed in any special way in order to be able to be inserted except that it must be adapted to the opening, or fit into it and be held in place, ie. without gaps being formed, especially being shaped. The fastening element may consist of a plate or have another suitable shape.

If the fastening element is to be inserted into solid foam, the shape is of a slightly greater importance to facilitate insertion. For example, "it is appropriate if it is thinner, narrower, sharper or sharper or the like in the part which initiates the insertion.

An example of such a fastener 4OB is shown in Fig. 6B.

Fig. 7A schematically shows examples of how concrete molds 100,1OW with first and second wall forming devices 10,10 '; (For the second floor-forming concrete mold 100 ', for reasons of clarity, no other wall-forming device is shown) according to the invention may be provided in the construction of a house or the like. It should thus be clear that a single-wall forming device is not limited to a device forming a wall in the conventional sense but can likewise form a floor etc. The schematic figure also shows reinforcement 80,80 ', but before casting has taken place. in? Fig. 7B shows very schematically a small part of a concrete form according to the invention where also electrical equipment in the form of drain lines 85 is drawn and apparatus box 86 and ventilation equipment 87 are mounted, and the second wall forming device 20 is attached to the first 10 by means of mold rods 30, but before casting . The casting equipment can be mounted with knot wire in the reinforcement 80 with nails in the mold plate 10, by clamping the intermediate cellular plastic and mold plate with the device provided for this purpose.

In general, different types of foam blocks, or second wall forming devices in general, which are provided with a gap or opening or the like, can be designed in very different ways and in different sizes, as well as foam blocks which have a prepared opening or the like can be designed in different ways. a number of examples of foam blocks are shown, for example, in Figs. 8A-8E below.

Fig. 8A shows an example of an element, foam block 111 which is not spontaneous but has a substantially square or rectangular cross-sectional shape. In the example shown, it is also not provided with a gap or receiving opening pre-fastening element. Alternatively, it could of course be provided with one or more such openings. 8B is a perspective view of a spontaneous foam block or rather Of course, such a Fig. As shown, for example, in Fig. 1, may not be provided with a receiving opening or similar elements may be provided with one or more receiving openings of the desired shape and size. A narrow elongate opening perpendicular to the intended longitudinal extension of a tie rod substantially orthogonal to the inner wall of the block generally provides a single holding capacity which is higher in that 18 should not be skewed at different under reinforcement, the tie rod ends up load stacking, wiring etc. and casting as the abutment surfaces become larger. However, other alternatives are also possible, for example holes for a plurality of rods in two or more parallel arranged as projecting from different planes, e.g. a planar triangle.8C-8E embodiments of, for example, show additional sheet piled blocks of block ll2, ll3, ll4; The figures element, it should be clear that cellular plastic blocks are not specified for limiting purposes, but also other building elements, of other materials can be used.

Cellular plastic block 113 is orthogonally spontaneous, with an intermediate sub-element 1133 which is set both in a direction relative to two surrounding sub-elements lln, 11e, and forms a spring / groove in this direction, as well as in a direction perpendicular to these element outer sides and forms a spring / groove also in this, other, orthogonal direction.

In alternative embodiments, building blocks, or special cellular plastic blocks, may be provided with molded-in or assembled reinforcements. This can make it possible for the distance, due to improved stability, between adjacent mold struts to be increased, which facilitates assembly, reduces cost and also simplifies reinforcement work and wiring, etc. because this is done with a tie rod in place.

Fig. 9A schematically shows an example of a corner device 70 that can be used for inner corners where two other wall-forming devices, mold plates 21, 21 meet, to increase stability and secure the positioning of the concrete mold before casting. Since it is not recessed in away corner regions of the concrete, it falls or can be easily removed when the mold discs are removed after casting. The corner device 70 can 19 be made of many different kinds of material, e.g. sheet or hard plastic.00% Cm Fig. 9B shows an example of an alternative corner device} QA which includes a fixed corner member 71A with two perpendicular wall sides 721,722, sheet or hard plastic or other suitable material. Between them, for example, of the same material as the mold plate, or of the perpendicular wall sides, at a distance from each other, support triangles 73 are arranged in parallel planes perpendicular to the plane of propagation of the wall sides, the purpose of which is to fix the corner at the desired angle (usually 90 °). The corner device 70A can, only one shown in to the width of, include fitting elements 75A; provide but need not, Figs. 9B, for adapting use mold plates 21. These fitting elements 75A, or fitting pieces, can be provided on one or two sides with recesses 22A in the same way as the mold plates 21 to enable attachment also the corner elements 70A reasons. with forming rods analogous to the forming discs. may be provided with such recesses 22 "of the same. Suitably the fitting elements may be cleavable to allow adjustment of the length (width) of a wall or the like.

Fig. 9C shows schematically how forming rods 30 with fastening elements 40 and with locking devices 50 are inserted and fastened in forming plates 21 and corner device 70A. After casting, the corner device 70A can be removed in an analogous manner as the mold discs are removed. elak Sf fi å10 shows a scaffold 200 which can advantageously be Fig. (eg a so-called casting bridge or casting scaffold) used in work with, for example, a wall, concrete form according to the invention or another form or wall or the like, and which can also be used as well as horizontally, support and adjust the concrete form or wall in connection with casting, especially during the casting operation itself.

According to different embodiments, the scaffold 200 may be provided with co-mounting elements which enable detachable mounting or fastening in the mold rod, mold lock or in the mold plate. In particular, one or more of these elements (mold rod, mold lock. GSM * or mold plate) are provided with cooperating mounting elements. in simple embodiments consist of co-operating or some form of quick-release fasteners, hooks, loops or the like, or snap-in mechanisms. 200 pairs of legs with two parallel legs shown second 202,202 sonl is articulated bottom bracket 203,203a flat 203,203 includes in that example a (post) connected to an outer end of respectively intended to be placed and rest on a base, for example a floor, where the opposite outer ends of the bottom strut are connected to each other in a first 20l, 20l.
