Referring to fig. 1, fig. 1 is a schematic structural diagram of an assembled wall according to the related art. In order to facilitate assembly, china starts to popularize and use a building system of a low-layer cold-formed thin-wall steel enclosure wall in 2000. In the related art, a cold-formed thin-wall steel composite wall body can be generally adopted as a building enclosure wall body. The cold-formed thin-wall steel structure system has high standardization degree, good earthquake resistance and environmental protection, but is mainly used for residential houses with three layers or less.

The cold-formed thin-wall steel building system in the prior art has the following problems in the aspect of earthquake resistance: (a) The side-resistant rigidity of the composite wall body in the cold-formed thin-wall steel building system in the prior art is low, so that the side-resistant capacity and the bearing capacity of the cold-formed thin-wall steel building system are low (b) from the aspect of ductility, the energy consumption capacity of the composite wall body in the cold-formed thin-wall steel building system in the prior art is lower than that of the frame structure and the enclosure wall structure; (c) From the perspective of multi-channel earthquake-proof fortification, the cold-formed thin-wall steel building system in the prior art only has one earthquake-proof fortification, and once the building is destroyed, the building collapses due to continuous earthquake; (d) From the aspect of impact resistance, the impact resistance of the composite wall body in the cold-formed thin-wall steel building system in the prior art is poor, and the safety coefficient in the use process is low.

The first steel plate 101 and the second steel plate 102 can serve as a double-layer steel plate shear wall, and when the wall is impacted by external environment, the first steel plate 101 and the second steel plate 102 can bear force together. Since the steel plates have good bearing capacity and energy consumption capacity, the composite wall body 000 can better resist impact from the external environment through the first steel plate 101 and the second steel plate 102 in the first protective layer 100.

Moreover, the integrity between the first steel plate 101 and the second steel plate 102 in the first protective layer 100 can be enhanced through the filling layer, so that the first protective layer 100 has more stable bearing capacity. In this way, when the impact from the external environment is received, the first steel plate 101 and the second steel plate 102 in the first protective layer 100 can better cooperate, so that the impact of the external environment can be counteracted, and the impact resistance of the composite wall body 000 is better.

In order to more clearly see the matching relationship between the second protective layer 300 and the first connecting member 400 and the second connecting member 500, please refer to fig. 4, fig. 4 is an exploded view of the composite wall shown in fig. 2 under another view angle provided by the embodiment of the present utility model. The second dimensional sheath 300 in the composite wall 000 can include: the third steel plate 301 and the fourth steel plate 302, and the second filling layer 303 between the third steel plate 301 and the fourth steel plate 302, the third steel plate 301 may have a third through hole A3 for passing through the first connection member 400 and a fourth through hole A4 for passing through the second connection member 500 thereon, and the second filling layer 303 may have a third connection groove for passing through the first connection member 400 and a fourth connection groove for passing through the second connection member 500 thereon. Here, the functions and functions of the third and fourth steel plates 301 and 302 in the second dimension protective layer 300 may refer to the functions and functions of the first and second steel plates 101 and 102 in the first dimension protective layer 100, and the functions and functions of the second filling layer 303 in the second dimension protective layer 300 may refer to the functions and functions of the first filling layer 103 in the first dimension protective layer 100, which will not be described again. It should be noted that each of the above-mentioned connecting grooves may be in communication with the corresponding numbered through holes, for example, the first connecting groove may be in communication with the first through hole.

The structural layer 200 in the composite wall 000 may be located between the first and second sheathing layers 100 and 300, and the structural layer 200 may have a first hole site K1 for passing through the first connector 400 and a second hole site K2 for passing through the second connector 500. Because the structural layer 200 can be located between the first and second protective layers 100 and 300, the composite wall 000 can have better overall performance through the structural layer 200, and the first and second protective layers 100 and 300 can also cooperate under the driving of the structural layer 200. In this way, the first and second sheathing layers 100, 200, 300 in the composite wall body 000 can all participate in the stress when the composite wall body 000 is impacted from the external environment. In this way, the load carrying capacity and energy consumption capacity of the composite wall 000 can be further improved.

Illustratively, the structural layer 200 may have structural rebars therein that are respectively connected to the first and second dimension jackets 100, 300, by which the structural layer 200 may be better connected to the first and second dimension jackets 100, 300 to form the composite wall 000. And, when the composite wall body 000 receives an impact from an external environment, the structural layer 200 may participate in the stress not only through the contact surface with the first or second sheathing layers 100 or 300, but also through the construction reinforcing bars connected with the first and second sheathing layers 100 and 300. In this way, the structural layer 200 can better participate in the stress of the composite wall 000, so that the composite wall 000 has higher bearing capacity and energy consumption capability.

The first steel plate 101, the second steel plate 102, the third steel plate 301 and the fourth steel plate 302 in the composite wall body 000 may have a rectangular shape, one end of the first connector 400 in the composite wall body 000 may be connected to a corner of the first steel plate 101 at a side of the first steel plate 101 near the second steel plate 102, the other end of the first connector 400 may be connected to a corner of the fourth steel plate 302 at a side of the fourth steel plate 302 near the third steel plate 301, and an orthographic projection of an axis of the first connector 400 on the first steel plate 101 may coincide with a diagonal line of the first steel plate 101. Thus, under the action of the first connecting piece 400, the first and second protective layers 100, 300 and the structural layer 200 can form a better integrated structure, when the composite wall 000 is impacted by external environment, the first connecting piece 400 can deform the first or fourth steel plate 101 or 302 to transfer the deformation to other structures in the composite wall 000, so that the first and second protective layers 100, 300 and the structural layer 200 in the composite steel plate can cooperate better, and the bearing capacity and energy consumption capability of the composite wall 000 can be ensured.

Here, the first connection member 400 can be connected with the first and fourth steel plates 101 and 302 by the first through hole A1 on the second steel plate 102 for passing through the first connection member 400, the third through hole A3 on the third steel plate 301 for passing through the first connection member 400, and the first hole K1 in the structural layer 200 for passing through the first connection member 400. For example, the first connection member 400 may be connected to the fourth steel plate 302 after passing through the first through hole A1, the first hole site K1, and the third through hole A3 after being connected to the first steel plate 101. Also, since the orthographic projection of the axis of the first connector 400 on the first steel plate 101 may coincide with one diagonal line of the first steel plate 101, that is, may be disposed along two diagonally opposite corners of the first steel plate 101 and the fourth steel plate 302, the first connector 400 can assist other structures in the composite wall body 000 against an impact by generating a tensile deformation after the composite wall body 000 receives an impact from an external environment. After the composite wall 000 is impacted by the external environment, the first, second and third sheaths 100, 300 and 300 are mainly deformed in shear deformation and compression deformation. In this way, the composite wall 000 may further have the first connecting piece 400, so after the composite wall 000 is impacted by the external environment, the structural deformations in the composite wall 000 may be more coordinated under the driving of the first connecting piece 400, so that the defect that a certain structure is subjected to serious shear deformation or compression deformation to withdraw from working in advance can be avoided. Thus, the composite wall 000 has high bearing capacity and energy consumption capacity and good ductility, so that the defect that the composite wall 000 is broken in a brittle manner after being subjected to large external impact can be reduced.

One end of the second connector 500 in the composite wall 000 may be connected to a corner of the first steel plate 101 at a side of the first steel plate 101 near the second steel plate 102, the other end of the second connector 500 may be connected to the fourth steel plate 302 at a side of the fourth steel plate 302 near the third steel plate 301, and an orthographic projection of an axis of the first connector 400 on the first steel plate 101 may coincide with another diagonal line of the first steel plate 101. The function and function of the second connector 500 in the composite wall 000 can be referred to as the function and function of the first connector 400 in the composite wall 000, and will not be described herein.

In summary, the present utility model provides a composite wall, including: the first protection layer, the structural layer, the second protection layer, the first connecting piece and the second connecting piece. Through first dimension sheath and second dimension sheath, the impact from the external environment can be better resisted to the composite wall body. When the composite wall is impacted by the external environment, the steel plates in the first and second protective layers can work cooperatively better, so that the impact of the external environment can be counteracted, and the impact resistance of the composite wall is guaranteed to be better. And when the composite wall is impacted by external environment, the structural layer can better participate in the stress of the composite wall, so that the composite wall has higher bearing capacity and energy consumption capacity. In addition, under the effect of first connecting piece and second connecting piece, first dimension sheath, second dimension sheath and structural layer can be better form an organic whole structure, when composite wall receives the impact from external environment, first connecting piece and second connecting piece can produce deformation transmission with first steel sheet or fourth steel sheet to other structures in the composite wall to make first dimension sheath, second dimension sheath and the structural layer in the composite steel sheet can be better cooperate, thereby can guarantee that composite wall's bearing capacity and power consumption ability are better.

In an embodiment of the present utility model, referring to fig. 3 and 4, the length of the first connecting member 400 may be equal to the length of the second connecting member 500, and the cross-sectional dimension of the first connecting member 400 may be equal to the cross-sectional dimension of the second connecting member 500. In this way, the first connector 400 may better cooperate with the second connector 500. Also, during the ex-situ process, the first connector 400 may be formed in synchronization with the second connector 500, so that the ex-situ efficiency of the composite wall body 000 may be further improved.

For example, since the length of the first connector 400 is equal to the length of the second connector 500 and the sizes of the first connector 400 and the second connector 500 are also equal, the deformation of the first connector 400 and the second connector 500 can be maintained to be uniform even after the composite wall 000 receives an impact from the external environment. In this way, the same side force resistance condition of the first connector 400 and the second connector 500 can be ensured, so that the defect that the composite wall 000 is damaged due to the fact that the first connector 400 or the second connector 500 is withdrawn from working in advance can be avoided.

It should be noted that, in the drawings in the present utility model, the sizes and shapes of the first and second connection members 400 and 500 are simplified for convenience of illustration. In an embodiment of the present utility model, referring to fig. 3 and 4, the dimensions of the cross sections of the first through hole A1, the second through hole A2, the third through hole A3, the fourth through hole A4, the first connecting groove, the second connecting groove, the third connecting groove, the fourth connecting groove, the first hole site K1, and the second hole site K2 parallel to the first steel plate 101 in the composite wall 000 may be equal to the dimensions of the cross sections of the first connecting piece 400 and/or the second connecting piece 500 parallel to the first steel plate 101. Thus, the first connecting member 400 can better pass through the first through hole A1, the third through hole A3, the first connecting groove, the third connecting groove and the first hole site K1 to be connected with the first steel plate 101 and the fourth steel plate 302, and the second connecting member 500 can better pass through the second through hole A2, the fourth through hole A4, the second connecting groove, the fourth connecting groove and the second hole site K2 to be connected with the first steel plate 101 and the fourth steel plate 302. Thus, the first connector 400 and the second connector 500 can be ensured to be stably fixed in the composite wall 000, and after the composite wall 000 is impacted by external environment, the first connector 400 and the second connector 500 can be better stressed in cooperation with other structures in the composite wall 000, so that the integrity of the composite wall 000 can be further provided.

By way of example, since the first through-hole A1, the second through-hole A2, the third through-hole A3, the fourth through-hole A4, the first connecting groove, the second connecting groove, the third connecting groove, the fourth connecting groove, the first hole site K1, and the second hole site K2 in the composite wall 000 may have the same dimensions parallel to the cross-section of the first steel plate 101 as the first connecting member 400 and/or the second connecting member 500, the first filling layer 103, the second steel plate 102, the structural layer 200, the third steel plate 301, and the second filling layer 303 may be better connected to the first connecting member 400 and the second connecting member 500, and the deformation of the first filling layer 103, the second steel plate 102, the structural layer 200, the third steel plate 301, and the second filling layer 303 may be better transferred to the first connecting member 400 and the second connecting member 500, and the first connecting member 400 and the second connecting member 500 may be better cooperated with the respective layers of the composite wall 000 after the composite wall 000 is subjected to an impact from the external environment.

In the embodiment of the present utility model, there are various ways in which both ends of the first and second connection members 400 and 500 are connected to the first and second steel plates 101 and 102. The utility model is schematically illustrated in only two possible implementations.

In one possible implementation, as shown in fig. 4, both ends of the first and second connection members 400 and 500 may be connected with the first and fourth steel plates 101 and 302 by welding. In this way, the first and second connectors 400 and 500 can be connected to the first and fourth steel plates 101 and 302 in a fixed manner by welding, so that the load-bearing capacity and energy-consuming capacity of the composite wall body 000 can be further improved.

In another possible implementation, please refer to fig. 5, fig. 5 is a schematic structural diagram of another composite wall according to an embodiment of the present utility model. The first and fourth steel plates 101 and 302 may have connection holes through which the first and second connection members 400 and 500 can pass. The first and second connection members 400 and 500 may protrude from the first steel plate 101 near one end of the first steel plate 101, and the first and second connection members 400 and 500 may protrude from the fourth steel plate 302 near one end of the fourth steel plate 302. Also, both ends of the first and second connection members 400 and 500 may have a screw structure, and the first and second connection members 400 and 500 may be connected with the first and fourth steel plates 101 and 302 by the connection members L in a bolt-connection manner. In this way, the first and second connectors 400 and 500 can be connected to the second and fourth steel plates 102 and 302 in a biased hinged manner by means of bolting. In this way, after the composite wall 000 receives the final stage from the external environment, the first and second connectors 400 and 500 can be deformed in cooperation with each layer structure in the composite wall 000, and the degree of deformation of the first and second connectors 400 and 500 is higher. Since the materials of the first and second connectors 400 and 500 may be steel materials, the first and second connectors 400 and 500 can make the ductility of the composite wall body 000 good through the good ductility of the steel materials.

In the embodiment of the present utility model, the materials of the first filling layer 103, the second filling layer 303, and the structural layer 200 in the composite wall 000 are not particularly limited. Only the following materials are schematically illustrated:

in the present utility model, the materials of the first filling layer 103 and the second filling layer 303 may be a first concrete or a perlite insulation material. Here, the first concrete may be foam concrete. Because the self weight of the foam concrete and the perlite heat insulation material is lighter, the foam concrete and the perlite heat insulation material have better heat insulation effect and better ductility performance. Therefore, the first and second filler layers 103 and 303 can provide the composite wall 000 with a good heat insulation effect and ductility, and also can ensure that the composite wall 000 has a light weight. In the construction process of the composite wall 000 for the fabricated building, an operator can more conveniently adjust the position of the composite wall 000.

The material of the structural layer 200 in the composite wall 000 may be a second concrete. The second concrete may be a concrete composited with a fibrous material. The fiber material can further improve the ductility of the structural layer 200, so that the second concrete has better ductility while having better bearing capacity. Therefore, the bearing capacity and the energy consumption capacity of the composite wall body 000 can be high, and after the composite wall body 000 is impacted by the external environment, the composite wall body 000 can be damaged in plastic. Thus, when the composite wall body 000 is used as a surrounding wall body of a road or a bridge, after a vehicle collides with a surrounding wall plate, the composite wall body 000 can show better ductility, so that the vehicle can be better protected, and the adverse condition that the vehicle and a user carrying the vehicle are secondarily injured due to the damage of the vehicle due to the fact that the strength of the wallboard is higher but the ductility is poor after the vehicle collides with the composite wall body 000 is avoided; when the composite wall body 000 is used as a building enclosure wall body, the composite wall body 000 can not only perform better heat preservation on the building, but also improve the anti-seismic performance of the building through better bearing capacity and ductility.

By way of example, the fibrous material of the structural layer 200 in the composite wall 000 may be composited with the structural layer 200 in a variety of possible implementations. The utility model is schematically illustrated in the following two possible implementations.

In one possible implementation, the fibrous material may be compounded with the second concrete in the form of aggregate. In this case, the second concrete comprises cement, fly ash, sand, fiber material, water reducer and water, wherein the mass ratio of the cement, the fly ash, the sand and the water is as follows: 1:1:0.76:0.55, wherein the fiber material accounts for 1.45 percent of the total volume of the second concrete, and the water reducing agent accounts for 0.8 percent of the total mass of the cement, the fly ash and the sand.
