Description

  The present invention relates to a scaffold system having structural units and an assembly method thereof.

  In the field of architecture, it is necessary to work at different heights. For this reason, it is possible to use various structural units (hereinafter referred to as scaffold units) that can constitute the scaffold system by arranging them vertically. Different heights or working positions can be reached by arranging different scaffold units up and down. Such a scaffold system is particularly useful when assembling and disassembling the ceiling formwork. Furthermore, such a scaffold system is used to reduce the formwork load.

(Prior art)
Some scaffold units can be known from the prior literature, but such a scaffold system can be used when a combination of scaffold units with different working position heights is required to set a working position close to ideal. There may be disadvantages.

  Furthermore, the height of the passage between the scaffold units assembled up and down is often 1.8 meters or less, especially due to the height of the individual component units. For this reason, it is necessary for a person to bend and pass, increasing the risk of colliding with the crossbar.

  EP0014623A1 discloses a scaffold system in which the height of the scaffold for determining the work position is fixedly determined in advance.

  DE 1740990U discloses a scaffold unit in which vertical tubes are arranged in a horizontal direction on a support structure movable in the vertical direction and fixed with screw bolts.

  The object of the present invention is to solve the problems in the prior art and to create a scaffold system with a simplified structure. Furthermore, this advantage is obtained by the method of assembling the scaffold system and the use of the scaffold system.

  The object is achieved firstly by a scaffold system as claimed in claim 1.

  According to claim 1, the scaffold system comprises at least two scaffold units comprising two struts arranged substantially parallel to each other and at least two reinforcements reinforcing the parallel arrangement. The scaffold unit is attached between two struts and has only one lateral connecting member that connects the two supporting posts, and the reinforcing member is disposed on the lateral connecting member. In use, the struts stand upright with respect to the ground and all elements, i.e. the two struts, the stiffeners, and the cross-links, lie substantially in one plane. Preferably, two or more scaffold units are arranged in parallel planes arranged at the front and back, respectively, so that each unit is not inclined by a lateral reinforcement member or a brace provided between the scaffold units. To stabilize.

  Thus, a stable scaffold system can be advantageously provided by a scaffold unit having only one lateral connecting member. Furthermore, a particularly stable scaffold unit can be provided by adapting the reinforcing material to the lateral connection material. The reinforcement is simply extended from the struts to the lateral connection without passing between the two struts and without crossing.

  In this way, since only one horizontal connecting member is provided and the reinforcing member is provided on the side, it is particularly useful in that a path substantially free of obstacles is provided between the constituent units arranged at the front and rear. It is. According to the scaffold unit of the present invention, it is possible to reduce the cost and weight by reducing the use of the material of the reinforcing material while having high stability. Further, the weight reduction allows ergonomic handling in the assembly and disassembly of the scaffold unit according to the present invention.

  In the longitudinal extension direction of the support columns, the lateral coupling members are arranged asymmetrically. Thereby, by installing the scaffold unit having the same shape upside down, the lateral coupling members can be arranged at different heights as necessary. And especially a high channel | path can be provided between the scaffold units arrange | positioned up and down.

  The scaffold unit is further arranged vertically to constitute a scaffold system. In order to connect the scaffolding unit, it proves to be particularly advantageous to provide at least one strut end with at least one orifice to which the joining part fits. This makes it particularly advantageous to arrange and connect several scaffold units up and down, with the asymmetrical lateral coupling material directed in different directions.

  According to one development, the reinforcing material is arranged such that a passage is formed between the attachment points of the reinforcing material in the lateral coupling material. And when several scaffold units are arrange | positioned back and forth, the channel | path without an obstruction can be especially provided between scaffold units. A safety member, specifically a handrail, can be provided at the end of such a passage, ie at least one of the foremost and last scaffold units. That is, it is possible to attach the safety member to the lateral connection member or the support column in a method that can be easily removed. And it can prevent especially advantageously that a person or an object falls.

  As described above, the scaffold system is assembled by arranging several scaffold units one above the other. Then, the asymmetrically arranged lateral connecting members are appropriately installed in the upper half or lower half, and the working place between individual scaffold units and the height of the passage can be changed particularly advantageously.

  According to a particularly preferred embodiment, a lateral coupling member arranged substantially parallel to the ground, wherein a walking support surface is arranged between the respective lateral coupling members of the two scaffold units. According to this method, a tool can be placed, and a surface on which a person stands can be provided particularly advantageously.

The objects of the invention are also achieved by a method of assembling a scaffold system. There, a first scaffold unit having two struts and a laterally connected material provided asymmetrically is first set up. The horizontal connecting member defines a large and small passage surface between the two columns. Next, a second scaffold unit having two struts and a lateral coupling member provided asymmetrically is connected to the first scaffold unit. The horizontal connecting member of the second scaffold unit also defines a large and small passage surface between the two support columns. And the direction of the horizontal connection material of a 2nd scaffold unit differs from a 1st scaffold unit, and adjoins two big channel | path surfaces. It is also possible to arrange so that two small passage surfaces are adjacent. These two steps can be repeated as appropriate until the scaffold system is assembled to the desired height. Needless to say, when the third scaffolding unit is stood on the second component unit, two small passage surfaces are placed adjacent to each other, or one small passage surface and one large passage. It is only possible to arrange the road surface next to each other. According to this method, in any case, the scaffold system can be advantageously assembled so that an ideal working height and working position can be obtained by appropriate arrangement of the asymmetrically provided lateral coupling members. .
Furthermore, the advantages of the invention are shown by the use of a scaffold system according to claim 7.

  The invention will be described in detail with reference to the examples shown in the following figures.

Top view of scaffolding system with two scaffolding units arranged one above the other Connecting parts that connect two scaffolding units Another embodiment of the scaffold unit according to the present invention

  FIG. 1 shows two scaffold units 10 that are arranged one above the other to form a scaffold system 20. The scaffold unit 10 has two parallel struts 12 respectively. The struts 12 are integrally connected by a horizontal connecting member 16. The horizontal connecting member 16 shown in the present embodiment is asymmetric in the vertical direction in which the support column 12 extends, that is, is arranged in the upper half or the lower half of the support column. The two struts 12 arranged on the upper and lower sides are integrally connected via a connection component 24 (not shown).

  The reinforcing member 14 extends obliquely from the support column 12 to the lateral coupling member 16. This increases the rigidity of the scaffold unit. One reinforcing member 14 extends obliquely from the respective support column to the horizontal connecting member on the upper surface of the horizontal connecting member 16, and the other reinforcing member 14 extends on the lower surface of the horizontal connecting member 16. It extends diagonally from the column to the lateral connection.

  The reinforcing member 14 is welded to the lateral connecting member 16 and the support column 12. Moreover, the form fixed with a screw, a rivet, etc. may be sufficient.

  As shown in FIG. 1, a scaffold system 20 can be configured by arranging several scaffold units vertically. In particular, since the horizontal connecting members 16 are arranged asymmetrically, the two scaffold units 10 having the same shape can be arranged vertically so that the directions of the horizontal connecting members 16 are reversed. This can be realized by arranging the scaffold unit 10 upside down in the opposite direction. Thus, a wide, narrow or intermediate passage area can be formed between two adjacent scaffold units as required. A wide passage area can be formed by arranging the two scaffold units 10 vertically so that the large passage surfaces of the scaffold units 10 are adjacent to each other. A narrow passage area can be formed between the two scaffold units 10 of the scaffold system 20 by placing the scaffold units 10 up and down so that the small passage surfaces are adjacent to each other. An intermediate passage area can be formed between the two scaffold units 10 of the scaffold system 20 by placing the scaffold units 10 up and down, with the asymmetrical lateral coupling 16 in the same direction.

  Furthermore, a support surface capable of walking can be disposed between the two scaffold units 10 disposed substantially front and rear. The support surface is securely held in both directions of placement of the scaffold unit 10 and is held on the lateral coupling member 16 so that it can walk.

  By providing several scaffold units at the top and bottom and / or front and back, there is provided a scaffold system capable of forming different passage heights (low, medium and high) between the top and bottom scaffold units. be able to.

  In order to ensure a large freedom of configurable work height and passage height, the scaffold units 10 of different heights can be interchanged. For example, the scaffold unit 10 can have a height of approximately 1.8 m, 1.2 m, or 0.9 m. The horizontal connecting member 16 is preferably asymmetrically arranged at a height of one third of the support column 12 according to each case. And, for example, by arranging two 1.8 m-high struts vertically so that the direction of the horizontal connecting material is different (wide passage area), a theoretical passage height of 2.4 m (2 × 1. Even if the height of the horizontal connecting material is subtracted from 2 m), a passage height exceeding 2 m can be obtained.

  The safety member is specifically a handrail, but is detachably disposed between the reinforcing members 14 or the ends of the passages between the columns 12 in order to prevent injury. On both sides of the lateral connecting member 16, a fixing point of the safety member 19 is provided on at least one of the reinforcing member 14 and the support column 12. When the safety member is disposed on the reinforcing member 14, the length must be adjustable so that the safety member can be attached to the reinforcing member 14 on both sides of the lateral coupling member 16.

  In the scaffold system 20 having the scaffold unit 10 disposed above and below, a joining component is disposed between the two scaffold units 10 in order to dispose the scaffold unit vertically.

  FIG. 2 illustrates such a joining component 24. The connecting piece 24 is inserted into the strut 12 until it contacts an insertion limiter 28 having a larger diameter than the strut 12 which preferably has a circular cross section. And the fixing | fixed part 26 engages with the fixing hole formed in the support | pillar 12. FIG. The scaffold unit 10 adapted to the connection component 24 and placed on the scaffold unit 10 is connected in the same manner using the connection component 24. Thereby, the flexible vertical arrangement | positioning of the scaffold unit 10 is ensured, and the scaffold system 20 is comprised.

  Another method may be used to fix the support column 12 and the connection component 24. The connection component 24 is fixed or fastened to the column 12 by, for example, a push bolt, a lynch pin, a clip, or the like.

  The ends of the struts 12 or connecting parts 24 have dimensions that allow the spindle to be screwed into both the struts 12 and the connecting parts 24. The spindle compensates for the height of the post placed on the ground. This allows the scaffold unit to stand on uneven ground and its height is adjusted accurately. Such spindles are used in the field of architecture.

  FIG. 3 shows another embodiment of the scaffold unit 10 according to the present invention. The same or similar elements are given the same reference numerals. FIG. 3 shows a scaffold unit 10 with the length of the strut 12 being less than 1.4 m, preferably approximately 0.9 m or 1.2 m. This scaffold unit 10 is advantageous in that each strut 12 is provided with only one reinforcing member 14 similar to that shown in FIG. The lateral coupling member 12 is disposed asymmetrically, and the reinforcing member 14 is preferably provided on the side where the long portion of the column 12 of the lateral coupling member 12 extends. The embodiment of FIG. 3 has two reinforcing members on each side.

  In all the embodiments, the reinforcing member 14 is disposed on one support column 12 of the scaffold unit 10 on the lower side of the horizontal coupling member 16, and the reinforcing member 14 is disposed on the other support column 12 on the upper side of the horizontal coupling member 16. Is possible.
