Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, and specifically relates to an insulated sandwich wall for prefabricated buildings. Background Technology

[0002] Prefabricated insulated wall panels are prefabricated exterior wall panels that integrate insulation functions. They are prefabricated in a factory and then transported to the construction site for assembly, thereby achieving fast and efficient construction of building exterior walls.

[0003] During construction, in order to prevent unevenness and cracking at the joints of wall panels, a plaster layer is usually added at the joints. However, the plaster layer construction takes a long time and consumes a lot of materials, which greatly increases the construction cost. At the same time, the area of ​​the plaster layer also affects the connection strength between the plaster layer and the wall panel. If the area of ​​the plaster layer is reduced in order to reduce costs, problems such as easy cracking at the joints of the wall panels and plaster layer falling off will occur. Utility Model Content

[0004] To address the existing technical problems, this utility model proposes an insulated sandwich wall for prefabricated buildings. The purpose of this utility model and the solution to its technical problems are achieved by the following technical solutions.

[0005] According to this utility model, an insulated sandwich wall for prefabricated buildings is provided. The wall includes an insulation board, a wire mesh, and a polystyrene particle cement board. Polystyrene particle cement boards are respectively provided on both sides of the insulation board. The wire mesh is located inside the polystyrene particle cement board, and the two wire meshes are connected by several connecting wires that penetrate the insulation board. The ends of both sides of the wall are provided with vertically extending slots. Several first reinforcing slots are evenly distributed on the bottom surface of the slots. One end of the wall is provided with a protrusion, and the other end is provided with a recess that matches the protrusion. After the two walls are joined together, the two corresponding slots form a plastering groove.

[0006] Furthermore, the wire mesh is a double-layer wire mesh.

[0007] Furthermore, the protrusion and recess are joined together to form a joint between the two walls, and the corresponding two grooves form plaster grooves that cover the aforementioned joint.

[0008] Furthermore, the two side surfaces of the plastering groove are inclined surfaces.

[0009] Furthermore, several second reinforcing grooves are provided on the side groove surface.

[0010] Furthermore, the cross-section of the plastering groove is trapezoidal.

[0011] In summary, this utility model has the following advantages:

[0012] (1) By setting up plastering grooves, the area to be plastered is reduced, construction time and material consumption are reduced, and construction costs are lowered.

[0013] (2) Setting a first reinforcing groove on the bottom surface of the plastering groove can increase the contact area between the plaster layer and the wall panel, improve the connection strength of the wall panel, and avoid the problem of plaster layer cracking and falling off, while reducing construction costs.

[0014] (3) Setting a protrusion and a matching recess can facilitate the splicing of two wall panels and improve work efficiency.

[0015] (4) The sides of the plastering groove are sloping, which makes it easy to fill the corners of the plastering groove with mortar, making it convenient for workers to carry out the construction.

[0016] (5) Compared with concrete walls, the polystyrene particle cement board used is lighter and easier to transport and assemble on site.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, preferred embodiments are given below, and detailed descriptions are provided in conjunction with the accompanying drawings.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1 This embodiment describes an insulated sandwich wall for prefabricated buildings, comprising an insulation board 4, double-layer steel wire mesh 2, and polystyrene particle cement board 5. The polystyrene particle cement board 5 is disposed on both sides of the insulation board 4, and the double-layer steel wire mesh 2 is disposed inside the polystyrene particle cement board 5. Two double-layer steel wire meshes 2 are connected by several connecting wires 3 penetrating the insulation board 4. The connecting wires 3 are arranged along the thickness direction of the insulation board 4. In this embodiment, the thickness direction is... Figure 1 The horizontal direction is shown.

[0024] Please see Figure 2 One end of the wall is provided with a protrusion 7, and the other end is provided with a recess 8 that matches the protrusion 7. The cross-sections of both the protrusion 7 and the recess 8 are trapezoidal. The two walls are joined together by the protrusion 7 and the recess 8 to form a splicing seam 6 between the two walls, which facilitates the splicing work between the two wall panels.

[0025] Please see Figure 2 , Figure 3 and Figure 4 The wall has vertically extending slots 9 on both sides. In this embodiment, the vertical direction refers to the height of the wall. Several first reinforcing slots 10 are evenly distributed on the bottom surface of the slots 9. The shape and size of the first reinforcing slots 10 are not limited and can be determined according to construction needs. The slots 9 on the two walls are set at the joint end of the walls, and the two corresponding slots 9 form a plastering groove after the walls are joined. At the same time, the plastering groove covers the splicing joint 6. That is, several first reinforcing slots 10 are evenly distributed on the bottom surface of the plastering groove. The cross-section of the plastering groove is trapezoidal.

[0026] Furthermore, the two side groove surfaces 11 of the plastering groove are inclined, which makes it easy to fill the corners of the plastering groove with mortar, making it convenient for workers to carry out construction; at the same time, when the width of the side groove surface 11 is appropriate, several second reinforcing grooves can be set on it to further improve the tightness of the connection between the cooled cement mortar in the plastering groove and the wall, and further improve the connection strength.

[0027] When plastering, first fill the first reinforcing groove 10 with cement mortar (when a second reinforcing groove is set, fill the second reinforcing groove with cement mortar at the same time), and then plaster the plastering groove. This allows the cement mortar in the first reinforcing groove 10 and the cement mortar in the plastering groove to cool and solidify into one. This not only reduces the plastering area, construction time, and material consumption, thus lowering construction costs, but also increases the contact area between the plaster layer and the wall panel, improving the connection strength of the wall panel and avoiding the problem of plaster layer cracking and falling off.

[0028] In other embodiments of this embodiment, the double-layer wire mesh 2 can be replaced with a single-layer wire mesh or three or more layers of wire mesh, depending on the thickness of the concrete on both sides of the wall.

[0029] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
