Building wall structure

This creation is about a wall structure for building, especially a wall structure for building which has a large number of pores inside, which is light in weight, fireproof, heat-insulated, durable, and has good volume stability.

In the construction industry, lightweight aggregates are the backbone of lightweight concrete. The biggest difference between light concrete and normal heavy concrete is that the difference is mainly due to the filling of the aggregate. Lightweight aggregates can be roughly divided into natural and artificial, but the so-called lightweight concrete, in addition to the use of lightweight aggregates, there are various ways to mix it into lightweight concrete made of a large number of bubbles. In terms of lightweight aggregates, natural lightweight aggregates (meteorites; pumice; diatomite; pearlite, black slate, etc.) are mostly volcanic rocks, such as light cinders and slag, etc., followed by man-made Lightweight aggregate ("sintered" fly ash lightweight aggregate; "cold knot" fly ash lightweight aggregate, artificial sintered clay; foaming hearth; expanded shale, clay, schist), expanded styrene ( Styrofoam). After the Second World War, building materials were scarce and civil engineering construction was extensively built. However, in areas where natural bones were scarce, artificial light-weight aggregates began to be developed.

The type of artificial lightweight aggregate is quite complicated, and the cost of its manufacturing process will greatly increase its unit price. However, its most advantageous is the artificialization of the manufacturing process, and the degree of control of the properties can be controlled. The purpose of using lightweight aggregates is to reduce the weight of the concrete, as well as the heat insulation and strength requirements of the building. In the prior art, the dry-mixed lightweight concrete of the above materials has complicated mixing design and process on site; the quality and the quantity of use cannot be controlled; the plugging and pumping are often difficult, so the dry and light weight of the lightweight aggregate is used. The number of concrete cases is still limited.

Traditionally, the construction method of dry-mixed lightweight concrete is to use bagged cement and special package for bulk sand or dry-mixed slurry on site, and mix expanded polystyrene (styrofoam pellets) as lightweight aggregate. The construction method is often caused by the unstable honeycomb body (pseudo-combination) and the lack of fluidity caused by the shortage of the styrofoam particles. Its quality is always incomparable, and it has the phenomenon of poor sound insulation, insufficient nailing, and the inability to bear weight. The foamed polystyrene granule lightweight concrete has a unit weight of about 800~1400kg/m ³ and its material cannot be Decomposition causes thousands of years of garbage, does not meet environmental protection requirements, and the expanded polystyrene particles will decompose during the fire, emitting toxic gases (Shanxi gas), so the European and American countries have been banned. Accordingly, there is still no suitable wall structure for construction on the market.

One of the purposes of this creation is to propose a wall structure for building, which is light in weight, fireproof, heat and soundproof, durable corrosion resistant and good in volume stability.

Another object of the present invention is to provide a wall structure for a building that can be continuously utilized and meets environmental protection requirements.

For the above purposes and other purposes, the wall structure for the building of the present invention comprises: a frame module, a wall block; and a plurality of cover plates. The frame module set is set as a support frame with a hollow receiving portion. The plurality of cover plates cover the two side surfaces of the frame module. The wall block is a block formed by dry-mixed lightweight concrete containing a plurality of artificial lightweight aggregates and filled in the hollow receiving portion, each of the artificial lightweight aggregates having a particle diameter of 2 to 30 mm, each of which The artificial lightweight aggregate is formed by crushing an inorganic lightweight expanded ore which is at least used as a lightweight artificial stone block foam concrete and a recycled concrete aerated concrete. One of them formed.

In one embodiment of the present invention, each of the artificial lightweight aggregates has a porosity of 40 to 85%, an apparent density of 300 to 1000 kg/m ³ , and a thermal conductivity of 0.09 to 0.16 W/MK.

In an embodiment of the present invention, in the inorganic lightweight expanded ore formed by the foam concrete, the foamed concrete comprises a mixed substrate of at least one of a cement slurry and a cement mortar, and is foamed by a foaming agent. The inorganic foamed ore is formed by subsequent foam mixing and natural curing.

In an embodiment of the present invention, in the inorganic lightweight expanded ore formed by the aerated concrete, the aerated concrete comprises a metal foam-based foaming agent, and is composed of a calcium material and a siliceous material. The material is hydrated to form a companion mud, which is then subjected to a high temperature and high pressure curing procedure to form the inorganic lightweight expanded ore.

In one embodiment of the present invention, the calcium material is at least cement and lime. First, the siliceous material is at least one of sand, fly ash, mediate vermiculite, silicon-containing tailings, and slag.

In one embodiment of the present invention, the inorganic lightweight expanded ore is formed by a high temperature and high pressure maintenance program having a pressure of about 1 MPa and a water vapor having a temperature of about 180 ° C for at least 7 to 8 hours.

Therefore, due to the construction of the wall structure for building materials with inorganic materials, the creation is non-corrosive, non-combustible, and has a large number of pores inside, which is light in weight, fireproof, heat-insulated, durable, and dimensionally stable. Good characteristics and materials are recyclable resources, and sustainable use meets environmental protection requirements.

The combination of the frame module 110 and the cover plate 130 can form a grouting space of the wall, that is, the hollow receiving portion, to form the wall block 120 therein. After the wall block 120 is formed, the frame module 110 and the cover plate 130 can be removed to use the wall block 120 as a separate wall or roof panel, floor, etc., and the frame module 110 can be retained.

At least one of them is formed.

In one embodiment, each of the artificial lightweight aggregates has a porosity of 40 to 85%, an apparent density of 300 to 1000 kg/m ³ , and a thermal conductivity of 0.09 to 0.16 W/MK.

As for the inorganic light expansion ore formed by the foam concrete mentioned above In the stone, the foamed concrete comprises a mixed substrate of at least one of a cement slurry and a cement mortar, and the inorganic light expanded ore is formed by mixing and natural curing with a foaming agent after foaming. In the above-mentioned inorganic light expanded ore formed by the aerated concrete, the aerated concrete comprises a metal foam-based foaming agent, and is hydrated by the calcium material and the siliceous material. The mud is formed and then subjected to a high temperature and high pressure curing process to form the inorganic light expanded ore. Wherein the calcium material is at least one of cement and lime, and the siliceous material is at least one of sand, fly ash, mediaite, silicon-containing tailings and slag.

Described in a more detailed process of formation, the inorganic light expansion ore of this creation (Environmental pellets) The material of manufacture is a combination of lightweight artificial stone blocks and recycled blocks (such as foam concrete, aerated concrete, etc.) one). That is, the inorganic light expanded ore of the present invention is formed by using at least one of foamed concrete as a lightweight artificial stone block and aerated concrete as a recycled block as a base material, and then cured. Inorganic lightweight expanded ore.

Foam concrete forming the inorganic lightweight expanded ore comprises: providing At least one of the cement slurry and the cement mortar is used as a mixed substrate; the mixed substrate is mixed with the foam of the foaming agent after foaming; and a natural curing process is performed to form the inorganic light expanded ore. For example, foam concrete can be produced by mechanically fully foaming the foaming agent through a foaming system of a foaming machine, and then mixing the cement slurry or cement mortar with a stable foam. Then, through the pumping system of the foaming machine, the cast-in-place mold is formed, and then the natural curing is carried out to form a new type of lightweight heat insulating material containing a large number of closed pores, and has a concrete product with considerable strength.

For example, the aerated concrete may be an ALC (Autoclaved light-weight concrete, which is a high-pressure steam-cured lightweight concrete), and in one embodiment, the metal powder (aluminum powder) may be utilized. As a foaming agent, at least one of a calcium material (for example, at least one of cement and lime) and a siliceous material (for example, sand, fly ash, mediaite, silicon-containing tailings, slag, etc.) may be used. As a main raw material, a foaming agent, an additive, and the like are further added to these raw materials. Water, etc., mix into a mud and then pour into the model. Lime or cement will make the water alkaline during the hydration process, and the alkaline water will react with the aluminum powder mixed as a foaming agent to generate hydrogen gas to form bubbles. At the same time, after the hydration reaction, the cement slurry begins to condense, and the cement slurry expands upward in the model, and the expansion amount is about twice the volume to form a block shape, which can then be cut into a desired size by using a steel wire. Then, the maintenance procedure is carried out, which can be a high temperature and high pressure maintenance procedure, which is carried out with a water pressure of about 1 MPa and a temperature of about 180 ° C for at least 7-8 hours to achieve firm hardening to form the inorganic lightweight expanded ore. .

Combine to form dry mix lightweight concrete. Wherein, in a preferred embodiment, the volume ratio of the artificial lightweight aggregate to cement and sand may be 4:1:2 or 5:1:3. For example, the above-mentioned crushing treatment can be made into an artificial lightweight aggregate by processing the inorganic lightweight expanded ore by coarse crushing, cone crushing, particle size vibration screening processing, etc. through the crusher equipment. The artificial light-weight aggregates selected are preferably about 2 to 30 mm in size, and have a large number of pores and micropores (porosity of 40 to 85%) and an apparent density of 300 to 1000 kg/m ^{3 .} The thermal conductivity is 0.09~0.16W/MK. Such artificial lightweight aggregate has the characteristics of uniform texture distribution and sound absorption capacity of 0.09~0.19%. Therefore, the biggest advantage of aerated concrete in energy-saving wall materials is that it can save land resources, and its raw materials are widely sourced. The raw materials can be selected from river sand, fly ash, slag and coal gangue. Can be used as raw material for aerated concrete. In this way, not only can it be adapted to local conditions, but it can also be used for waste and is environmentally friendly.

In the implementation of dry-mixed lightweight concrete, the main raw materials may be artificial lightweight aggregates crushed by cement (for example: Portland cement), inorganic lightweight expanded ore (environmental pellets), sand (fine aggregate), The compound admixture is mixed with water and the like. Sand and artificial lightweight aggregates act as skeletons in concrete and inhibit the shrinkage of cement; cement and water form a cement slurry that is wrapped around the surface of artificial lightweight aggregates and fills the voids between the aggregates. The cement paste will play a lubricating role before hardening. At this time, it has better workability, that is, high fluidity, small slump loss, no bleeding, no pumping, low cost, high cost performance. . This dry-mixed lightweight concrete is non-combustible and does not emit harmful gases in case of fire. The fire resistance is 700 degrees, which is a first-class refractory material; in addition, its apparent density is 800~1950kg/m ³ ; the thermal conductivity is only about 0.25kcal/m. Below .hr. °C, the biggest advantage is light weight, low modulus of elasticity, good seismic performance and good fire resistance. It is preferably used in industrial and residential buildings, indoor compartments of offices, especially high-rise buildings. Under the premise of not affecting the safety of buildings and structures, the weight of the entire building can be reduced, and the cost of foundations can be reduced. Compared with concrete which is generally made of cement, sand, gravel and water, the dry-mixed lightweight concrete of this creation also has good sound insulation and heat insulation functions, and residents can enjoy a quieter and cooler living environment. Better construction materials can be found in Taiwan where seismic belts and material resources are scarce.

In summary, the biggest advantage of the wall structure for the building of this creation is the light weight (for mixing 1/4~1/2) of concrete, low thermal conductivity (1/6 of concrete), with excellent performances such as sound insulation, heat insulation, fire resistance, non-combustibility and environmental protection (the insulation capacity is 3~4 times that of clay bricks, 4~8 times of ordinary concrete) can be applied to general industrial and civil buildings, especially high-rise building light compartment grouting walls, which is of great significance in replacing some traditional concrete in high-rise buildings and structures.
