Description

Technical Field

[0001] This utility model relates to the field of building exterior wall insulation technology, and more particularly to the field of cast-in-place concrete self-insulating walls, specifically referring to a composite insulation board for cast-in-place concrete self-insulating walls with a concrete core and steel wire mesh frame. Background Technology

[0002] With the development of integrated building insulation and structural technology, self-insulating walls are increasingly being used in building structures. By utilizing the characteristics of self-insulating walls, which simultaneously provide insulation and enclosure functions, the construction process is simplified and on-site construction efficiency is greatly improved.

[0003] Currently, self-insulating walls typically employ a combination of insulation core material and wire mesh to form a composite insulation board. This is achieved by pouring concrete to bond the wire mesh and insulation core material together, and the concrete solidifies to form a unified structure. This integrated insulation and structural system, formed by simultaneously pouring concrete on both the inner and outer sides of the insulation core material, is simply called a concrete-core wire mesh composite insulation board system. This system not only achieves self-insulation of the exterior wall but also extends the service life of the insulation system, enabling the insulation and the wall to have the same lifespan.

[0004] However, since the concrete core steel wire mesh composite panel insulation system only relies on concrete to fix the insulation core material and the steel wire mesh together, the bonding strength is insufficient. Moreover, it is inconvenient to fix the steel wire mesh before pouring concrete, which often leads to the displacement of the steel wire mesh, which is not conducive to improving production efficiency. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a composite insulation board for cast-in-place concrete self-insulating walls with a concrete core and steel wire mesh frame, which reduces the displacement of the steel wire mesh and improves the overall connection strength.

[0006] This utility model is achieved through the following technical solution: a composite insulation board for cast-in-place concrete self-insulating walls with a concrete core and steel wire mesh frame is provided, including an insulation core material and a plurality of web wires passing through the insulation core material. The insulation core material has casting chambers on its left and right sides respectively, and a steel wire mesh is provided in at least one of the casting chambers. A connecting hole is opened in the insulation core material to connect the left casting chamber and the right casting chamber. The connecting hole and the casting chamber are filled with concrete. The steel wire mesh is fixed to the insulation core material as a whole by the concrete, and the steel wire mesh is fixed to the web wires.

[0007] This solution incorporates web wires to form a wire mesh frame structure together with the wire mesh. By utilizing the resistance of the insulation core material to the web wires and the rigidity of the web wires, the displacement of the wire mesh is reduced. Furthermore, by incorporating connecting holes, concrete can be directed to the slower-pouring side when the pouring of concrete on the left and right sides is asynchronous.

[0008] As an optimization, a tie rod is inserted through the connecting hole. One end of the tie rod is fixed to the wire mesh in the left casting chamber, and the other end is fixed to the concrete in the right casting chamber. The tie rod is perpendicular to the wire mesh on the left. This optimized solution further prevents the wire mesh from shifting by setting the tie rod perpendicular to the wire mesh on the left, fully utilizing the tie rod's strong axial compressive strength to avoid relative movement of the wire mesh.

[0009] As an optimization, the angle between the web wire and the tie rod is greater than 0 degrees and less than or equal to 45 degrees. This optimization scheme sets the web wire and tie rod at a certain angle, creating multi-directional positioning of the wire mesh and further improving the effect of preventing the wire mesh from shifting.

[0010] As an optimization, the two web wires adjacent to the front and rear of the tie rod are symmetrical about the tie rod. This optimization scheme makes the extension lines of the tie rod and web wires form a grid structure, which improves the structural strength of the insulation board.

[0011] As an optimization, the distance between the web wire and the wall of the connecting hole is not less than 1 / 4 of the thickness of the insulation core material. This optimization scheme avoids the web wire damaging the insulation core material structure at the connecting hole, thus ensuring the integrity of the insulation core material.

[0012] As an optimization, wire mesh is installed in both the left and right casting chambers, with the ends of the web wires and the ends of the tie rods welded to the wire mesh. This optimized scheme, by setting the web wires and tie rods to be welded to the wire mesh, facilitates and speeds up construction, and ensures high reliability of the connection. For shear walls, wire mesh is installed in the outer poured concrete; for infill walls, wire mesh is installed in both the left and right casting chambers, with the outer ends of the web wires of single-sided wire mesh, the ends of the web wires of double-sided wire mesh, and the ends of the tie rods welded to the wire mesh.

[0013] As an optimization, adjacent front and rear web wires are arranged in a figure-eight shape, with the larger gap ends of the two adjacent figure-eight shapes facing opposite directions. This optimization scheme makes the web wires form a mesh overall, further improving the effect of preventing the wire mesh from shifting.

[0014] The beneficial effects of this utility model are as follows: by setting the web wires and tie rods that pass through the insulation core material to form a steel wire mesh structure, the firmness of the connection with the insulation core material and the integrity of the steel wire mesh frame and the insulation core material are improved, and the displacement of the steel wire mesh is reduced; by opening the connecting holes in the insulation core material, the timeliness of the concrete flowing to the slower-pouring side when the two sides of the insulation core material are poured at different times is improved, preventing the occurrence of mold deviation and bulging, ensuring the construction quality, and meeting higher construction requirements.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] Example 1

[0021] like Figure 1 As shown in this embodiment, a composite insulation board for cast-in-place concrete self-insulating walls with a concrete core and steel wire mesh frame includes an insulation core material 1 and several web wires 7 passing through the insulation core material. The thickness direction of the insulation core material is left-right. In this embodiment, the insulation core material 1 has casting chambers on its left and right sides, and each casting chamber on both sides is provided with a steel wire mesh 3. The steel wire mesh is fixed to the web wires and is parallel to the insulation core material. A connecting hole 4 is opened in the insulation core material to connect the left casting chamber and the right casting chamber. The connecting hole 4 and the casting chamber are filled with concrete 2. The steel wire mesh is fixed to the insulation core material by the concrete. One end of each web wire is fixed to the steel wire mesh in the left casting chamber, and the other end of each web wire is fixed to the steel wire mesh in the right casting chamber.

[0022] A tie rod 5 is threaded through the connecting hole. One end of the tie rod 5 is fixedly connected to the wire mesh in the left casting chamber, and the other end of the tie rod 5 is fixedly connected to the wire mesh in the right casting chamber. The tie rod is perpendicular to the wire mesh on the left and right sides, respectively. In this embodiment, both ends of the web wire and both ends of the tie rod are welded to the wire mesh to ensure sufficient connection strength and improve construction efficiency.

[0023] The web wires obliquely pass through the insulation core material. The distance between the web wires and the wall of the connecting holes is not less than 1 / 4 of the thickness of the insulation core material. The angle between the web wires and the tie rods is greater than 0 degrees and less than or equal to 45 degrees. In this embodiment, the angle between the web wires and the tie rods is 45 degrees. The two web wires adjacent to the tie rods before and after are symmetrical about the tie rods.

[0024] As a preferred embodiment, the two adjacent web fibers in this embodiment are in the shape of an "eight", and the large gap ends of the two adjacent "eight" shapes face opposite directions. For a certain web fiber, the two adjacent web fibers in front and behind are parallel to each other, which not only forms a grid, improving the structural strength, but also facilitates construction.

[0025] The combined insulation board in this embodiment also includes a connector 6, which is used to fix the insulation core material 1 to the wire mesh 3 before pouring concrete. The connector 6 is prior art and will not be described in detail here.

[0026] Example 2

[0027] This embodiment is a single-sided wire mesh structure, suitable for shear walls. Specifically, as shown... Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that a wire mesh 3 is provided in the casting chamber on the left side. The ends of the web wires and tie rods extending into the casting chamber on the left side are welded to the wire mesh. The ends of the web wires and tie rods extending into the casting chamber on the right side are fixed in the concrete of the casting chamber on the right side. After the concrete solidifies, the web wires, tie rods, insulation core material and wire mesh are fixed together as one unit.

[0028] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.
