[0032] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0033] The utility model discloses an assembled prefabricated concrete composite thermal insulation wall panel, which aims to solve the technical problems in the prior art that too many wall layers lead to poor interface compatibility and easy hollowing and falling, and that organic thermal insulation panels are flammable and have fire hazards. The utility model takes into account the structural strength, thermal performance and fire resistance of the prefabricated wall panel, and is more convenient for industrial production and local repairs during construction. The assembled prefabricated concrete composite thermal insulation wall panel disclosed by the utility model is particularly suitable for the exterior wall enclosure structure of frame buildings and steel structure buildings, and is easy to assemble.

Preferably, the insulation board 1 includes a ceramic foam board, a thermosetting composite polystyrene board or a homogeneous polystyrene board. In this embodiment, an A-class fireproof insulation board is used, which can effectively ensure the fire resistance. Compared with the solution of using a multi-layer organic board form insulation board in the prior art, the fire resistance can be guaranteed while reducing the number of insulation board layers. The multi-layer wall panel form is not convenient for local repair of the wall panel, while the two-layer wall panel solution in this embodiment can clearly locate the damaged position, which is convenient for local repair of the wall panel.

[0036] Furthermore, the insulation board 1 in the present application is bonded to one side of the precast concrete wall panel 2, and the insulation board 1 and the precast concrete wall panel 2 are anchored and connected by anchors. Compared with the multi-layer wall panel bonding solution in the prior art, this solution only uses two layers of wall panels, and the two layers of wall panels are first bonded by mortar 4 and then connected by anchors, which can effectively improve the connection strength between the wall panels and avoid the problem of easy falling off due to poor interface compatibility.

[0037] Furthermore, the anchors are evenly distributed on the precast concrete wall panels, and the distribution density of the anchors is not less than 5 per square meter. In a preferred embodiment, the anchors include connecting anchor bolts 3, which penetrate the insulation board 1, one end of the connecting anchor bolts 3 is anchored in the anchor hole of the precast concrete wall panel 2, the other end of the connecting anchor bolts 3 is located outside the insulation board 1, and the end of the connecting anchor bolts 3 located inside the insulation board 1 is fixedly connected to an anchor plate. The connecting anchor bolts 3 and the anchor plate are stainless steel anchor bolts and stainless steel anchor plates, respectively, and the connection strength between the two layers of wall panels can be further improved by the anchor plate.

[0038] Example 2

[0039] This embodiment is a preferred embodiment of the above basic embodiment, and is intended to solve the technical problem that the embedded depth and embedded part volume of the connecting rod in the prior art will affect the structural strength and stability of the wall panels after connection.

[0040] The metal L-shaped connecting plate 5 includes a vertical plate and a horizontal plate, the vertical plate is provided with a first connecting hole 12 matching the connecting rod 8, the horizontal plate is provided with a second connecting hole matching the expansion anchor 6, the expansion anchor 6 passes through the second connecting hole and is anchored in the external floor; the connecting rod 8 passes through the connecting through hole reserved in the thickness direction of the precast concrete wall panel 2, and one end of the connecting rod 8 passes through the first connecting hole 12 and is connected to the connecting nut 7, and the other end of the connecting rod 8 is located on the side of the precast concrete wall panel 2 close to the insulation board 1. Preferably, the connecting rod 8 is anchored in the precast concrete wall panel 2; the external floor panel includes an upper floor panel 9 and a lower floor panel 10, and the top and bottom of the precast concrete wall panel 2 are respectively fixedly connected to the upper floor panel 9 and the lower floor panel 10 through the floor panel connection assembly.

[0041] Further, such as Figure 1 As shown, the side of the precast concrete wall panel 2 away from the insulation board 1 is provided with a mounting groove 11 corresponding to the floor connection assembly, the connecting nut 7 and a part of the metal L-shaped connecting plate 5 are both located in the mounting groove 11, and the horizontal plate of the metal L-shaped connecting plate 5 partially extends out of the mounting groove and is anchored in the external floor by the expansion anchor bolt 6;

[0042] This embodiment uses a connecting rod 8 that runs through the entire precast concrete wall panel 2, which can transmit external forces to the entire precast concrete wall panel 2, further ensuring the structural stability and avoiding the problem that external forces will be transmitted to the interior of the precast concrete wall panel when the connecting parts are only embedded in the precast concrete wall panel to a certain depth, which may easily cause damage to the wall panel.
