Description

Technical Field

[0001] The utility model relates to the technical field of external wall panel connection, in particular to a connection device for a rock wool polyurethane edge-sealed external wall panel. Background Technique

[0002] As a kind of external wall panel material for a building, the rock wool polyurethane edge-sealed external wall panel is widely used in building insulation.

[0003] For example, a rock wool polyurethane edge-sealed seamless external wall panel with the patent number CN216075706U includes a metal panel, reinforcing mesh members arranged at intervals in the metal panel, a rock wool core material filled in the middle of the metal panel, and polyurethane edge seals filled at both ends of the metal panel; a first connection end is arranged at one end of the metal panel, and a second connection end matching the first connection end is arranged at the other end. However, the above document still has deficiencies. During use, the reinforcing mesh members can play a good role in supporting the metal panel, improving the anti-deformation performance of the sandwich panel. The partition support members can support the polyurethane edge seals, maintaining the stability of the shape of the polyurethane edge seals, reducing the mutual extrusion between them and the rock wool core material, and maintaining the stability of the internal structure of the external wall panel. However, when the existing rock wool polyurethane edge-sealed external wall panels are used for building insulation, they are usually adhered to the wall with mortar. This connection method has low strength, and the rock wool polyurethane edge-sealed external wall panels are prone to looseness and falling off, and the connection effect between the rock wool polyurethane edge-sealed external wall panels and the building is poor. At the same time, when the connected rock wool polyurethane edge-sealed external wall panels are connected, they are connected through a connection structure. The connection structure in the above document cannot be disassembled, and there will be a large gap between the rock wool polyurethane edge-sealed external wall panels at the edge position and the fitting surface during laying. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of poor connection effect between the rock wool polyurethane edge-sealed external wall panel and the building, and to propose a connection device for the rock wool polyurethane edge-sealed external wall panel.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design a connection device for a rock wool polyurethane edge-sealed external wall panel, including a rock wool polyurethane edge-sealed external wall panel and a first cylinder. The outer wall of the first cylinder is fixedly connected to the rock wool polyurethane edge-sealed external wall panel. A connection mechanism is arranged inside the first cylinder. The connection mechanism includes a second cylinder. The outer wall of the second cylinder is threadedly connected to the first cylinder. A ring is fixedly connected to the outer wall of the second cylinder. The outer wall of the ring is slidably connected to the first cylinder. A steel plate is fixedly connected above the second cylinder. The steel plate is in contact with the outer wall of the first cylinder. The steel plate is in contact with the outer wall of a tapered nut. A screw rod is fixedly connected below the tapered nut.

[0007] Preferably, a splicing mechanism is provided on the outer wall of the rock wool polyurethane edge-sealed exterior wall panel. The splicing mechanism includes connecting blocks. Two connecting blocks are respectively fixed on the left and right sides of the rock wool polyurethane edge-sealed exterior wall panel. A dovetail groove is provided inside the connecting block, and the dovetail groove is in clearance fit with the outer wall of the dovetail block.

[0008] Preferably, a buffer plate is fixed to the lower surface of the rock wool polyurethane edge-sealed exterior wall panel, and a reinforcing plate is fixed to the lower surface of the buffer plate.

[0009] Preferably, both the buffer plate and the reinforcing plate are fixedly connected to the outer walls of the first cylinder and the connecting block.

[0010] Preferably, a rubber plug is installed inside the first cylinder.

[0011] The beneficial effect of the connecting device for the rock wool polyurethane edge-sealed exterior wall panel proposed by the present utility model is as follows: Through the cooperation between the second cylinder, the ring, the steel plate, the tapered nut and the screw rod, the second cylinder is screwed into the inside of the first cylinder. The ring limits the depth of the second cylinder screwed in. The second cylinder is initially fixed inside the first cylinder. The screw rod is inserted into the first cylinder. By turning the tapered nut with a socket wrench, the tapered nut drives the screw rod to rotate. The screw rod is screwed into the building body. During the rotation of the tapered nut, it contacts the steel plate and drives the steel plate to move. The steel plate deforms and fits tightly against the inner wall of the first cylinder, thereby further fixing the position of the second cylinder and the first cylinder. The connecting mechanism fixes the rock wool polyurethane edge-sealed exterior wall panel, the buffer plate and the reinforcing plate on the surface of the building body. The rock wool polyurethane edge-sealed exterior wall panel is not prone to looseness and falling off, and the connection effect between the rock wool polyurethane edge-sealed exterior wall panel and the building body is better.

[0012] Through the cooperation between the connecting block, the dovetail groove and the dovetail block, after the previous rock wool polyurethane edge-sealed exterior wall panel is connected and fixed to the building body, the dovetail block is inserted into the dovetail groove in the connecting block fixed to the outer wall of the previous rock wool polyurethane edge-sealed exterior wall panel. Then, the dovetail groove in the connecting block fixed to the rock wool polyurethane edge-sealed exterior wall panel is sleeved on the outer wall of the dovetail block to realize the splicing between two rock wool polyurethane edge-sealed exterior wall panels. The dovetail block can be disassembled. When laying at the edge position, the connecting block can be closely attached to the edge position, and there will be no large gap between the rock wool polyurethane edge-sealed exterior wall panel at the edge position and the fitting surface during laying.
