It requires a lot of vertical and horizontal reinforcement during construction, which is relatively complicated and costly. In addition, the large number of diagonal insertions leads to more cold bridges when constructing the exterior wall, making it difficult to manufacture ultra-low energy consumption exterior walls.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] Reference Figures 1 to 7 This utility model provides a steel truss tie-reinforced wire mesh wall that does not require dismantling, including a ladder truss 1, a mesh structure 2 and a metal pressure plate 3;
[0036] The ladder truss 1 includes connected vertical steel bars 11 and horizontal tie rods 12. The vertical steel bars 11 are evenly distributed at equal intervals in the horizontal direction, and between two opposite vertical steel bars 11, several horizontal tie rods 12 are evenly distributed at equal intervals along the length of the vertical steel bars 11, so that all the horizontal tie rods 12 are arranged in an array. The connection is preferably welded to make the connection firm.
[0037] Each horizontal tie rod 12 is connected to a pair of metal pressure plates 3 at both ends. It is preferred to connect them with bolts. Since the horizontal tie rods 12 are arranged in an array in the vertical plane, the metal pressure plates 3 can also be arranged in an array.
[0038] A pair of metal plates 3 are actually two metal plates 3. The mesh structure 2 is connected between the two metal plates 3. The mesh structure 2 is a wire mesh. All the metal plates 3 can form a good reinforcement effect on the mesh structure 2. After controlling the spacing between the two mesh structures 2, a wall casting cavity can be formed between the two mesh structures 2.
[0039] Inside the wall casting cavity, other horizontal steel bars and pre-embedded conduits can be installed. After the concrete is poured, a concrete wall with a mesh structure 2 on the surface can be formed. After the surface of the wall is plastered and leveled, the finished wall can be obtained.
[0040] The steel truss-stretched reinforced wire mesh wall has good rigidity and is easy to maintain straightness. Construction reinforcement can be achieved by using the ladder truss 1 and metal pressure plate 3 in cooperation. The overall structure is simpler and the construction cost is lower.
[0041] As an optional implementation, the mesh structure 2 can be composed solely of coarse steel wire mesh 21;
[0042] Alternatively, the mesh structure 2 is composed of a coarse wire mesh 21 and a fine wire mesh 22, with the coarse wire mesh 21 connected to the outside of the fine wire mesh 22;
[0043] In both of the above configuration states, the coarse steel wire mesh 21 is connected to the metal pressure plate 3. Preferably, the metal pressure plate 3 is provided with a fixing groove, which is used to connect the steel wire of the coarse steel wire mesh 21.
[0044] In this embodiment, the coarse wire mesh 21 is preferably made of galvanized steel wire with a diameter of 3 mm or more, and the fine wire mesh 22 is preferably made of steel wire with a diameter of about 1 mm to form a 2x2 mm mesh. The fine wire mesh 22 is located inside the coarse wire mesh 21 and can be used to prevent the poured material from flowing out, allowing only a small amount of water or slurry in the concrete to flow out.
[0045] In addition, when necessary, the steel truss tie-reinforced wire mesh wall will also be equipped with insulation board 4. Insulation board 4 is a type of insulation board with a large density and a certain strength, which can resist the lateral pressure of concrete to a certain extent.
[0046] When the insulation board 4 is provided, the insulation board 4 can be connected to the horizontal tie rod 12. In addition, the horizontal tie rod 12 is connected to a metal pressure plate 3 on one side of the insulation board 4 or to a metal pressure plate 3 on each side of the insulation board 4. The corresponding metal pressure plate 3 can contact the insulation board 4.
[0047] In practical applications, this embodiment can form four different configurations of steel truss tie-reinforced wire mesh non-removable walls depending on whether insulation board 4 is set, as well as the different positions and quantities of insulation board 4.
[0048] Reference Figure 1 and Figure 2 For the first form, which corresponds to a wall without insulation board 4, the specific structural form is the same as the above setting method. The mesh structure 2 on both sides is connected together by ladder truss 1 and metal pressure plate 3.
[0049] Reference Figure 3 For the second form, it corresponds to a wall with a single layer of external insulation, that is, the number of insulation boards 4 connected to a single horizontal tie rod 12 is one, and the insulation board 4 is located between two mesh structures 2 and in contact with one of the mesh structures 2.
[0050] The mesh structure 2 in contact with the insulation board 4 includes a coarse steel wire mesh 21, and this side wall is equivalent to using the insulation board 4 and the coarse steel wire mesh 21 instead of the steel wire mesh.
[0051] The other side of the insulation board 4 is in contact with a metal pressure plate 3. The mesh structure 2 away from the insulation board 4 includes a coarse steel wire mesh 21 and a fine steel wire mesh 22. The mesh structure 2 away from the insulation board 4 and the insulation board 4 form a casting cavity.
[0052] Reference Figure 4 For the third form, which corresponds to a wall with double insulation, the number of insulation boards 4 connected to a single horizontal tie rod 12 is two. Both insulation boards 4 are located between two mesh structures 2 and are in contact with one mesh structure 2 respectively.
[0053] Each insulation board 4 has a metal pressure plate 3 on its other side, and a casting cavity is formed between the two insulation boards 4. Both mesh structures 2 include coarse steel wire mesh 21.
[0054] Reference Figure 5 For the fourth form, which corresponds to a sandwich insulation wall, the number of insulation boards 4 connected to a single horizontal tie rod 12 is one. The insulation board 4 is located between two mesh structures 2 and forms a casting cavity with any one of the mesh structures 2, so that the wall has two casting cavities.
[0055] Each side of the insulation board 4 is in contact with a metal pressure plate 3, and both mesh structures 2 include a coarse steel wire mesh 21 and a fine steel wire mesh 22.
[0056] The above four types of walls can be flexibly selected and used according to actual usage needs;
[0057] The above four types of walls, depending on the configuration of the reinforcing steel and the type of concrete poured, can be filled with concrete or lightweight concrete inside the wall casting cavity, serving as load-bearing or non-load-bearing walls. Load-bearing walls can be used in concrete structure buildings, while non-load-bearing walls can be combined with concrete frames or steel structure frames to serve as maintenance walls, offering a wide range of options.
[0058] As an alternative implementation method, in order to evenly distribute the pressure of the wall during the existing concrete building construction process, it is generally chosen to first construct the concrete footing, then install the wall formwork, install the wall reinforcement, and then pour concrete to form the wall. The above construction method requires pouring concrete twice, resulting in a "cold joint" between the foundation and the wall, which reduces the water tightness of the foundation. At the same time, the second pouring also increases the construction cost.
[0059] Therefore, in this embodiment, by taking advantage of the easy processing and bending characteristics of the wire mesh, the mesh structure 2 can be bent and used in conjunction with the horizontal tie rod 12 to make the enlarged footing of the cast-in-place concrete building.
[0060] Specifically, the bottom of the mesh structure 2 can be bent several times to form several bent parts 5. The mesh structure 2 corresponding to the bent parts 5 can enclose and form an enlarged foot casting cavity, which is connected to the wall casting cavity.
[0061] This design allows the enlarged foot casting cavity to be poured together with the wall casting cavity, casting concrete in one go to form a wall that is cast together with the concrete enlarged foot, thereby improving the water tightness and overall integrity of the building and reducing construction costs.
[0062] During construction, the vertical steel bars 11 of the building wall can continuously extend downwards to support the concrete pad. The entire non-removable wall is supported by the ladder truss 1. The ladder truss 1 is welded to the stirrups of the enlarged foot of the ring beam. Then, the stirrups of the enlarged foot are fixed to the concrete pad below with nails. Through the above process, the wall steel bars and the enlarged foot steel bars are connected together and a solid steel skeleton is formed by welding key nodes. The enlarged foot ring beam steel skeleton is covered with bent coarse wire mesh 21 and fine wire mesh 22 and tied and fixed with horizontal tie rods 12 to form a sealed enlarged foot casting cavity, which is connected to the wall casting cavity.
[0063] As an optional implementation, the ladder truss 1 also includes welding wires 13, which are connected to the vertical steel bars 11 and are staggered with the horizontal tie rods 12.
[0064] This configuration allows for a hybrid connection between the welding wire 13 and the horizontal tie rod 12. By replacing part of the horizontal tie rod 12 with the welding wire 13, costs can be effectively reduced without significantly affecting the structural strength, and the structural forms of the ladder truss 1 can be enriched.
[0065] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
