The connectors should have sufficient strength and durability to ensure the stability and safety of the exterior wall panels, and should also be easy to process and construct.

[0003] The current connection nodes of composite thermal insulation exterior wall panels generally use L-shaped or deformed L-shaped connectors, which have major problems: first, the L-shaped connector will protrude from the wall, and the later internal wall panel decoration cannot cover it, affecting the aesthetics of the wall; second, if the expansion bolts are driven directly from the bottom of the reinforced concrete beam, although its structural parts are hidden to a certain extent, the expansion bolts are too close to the side of the reinforced concrete beam, and it is easy to hit the steel bars of the reinforced concrete beam when drilling; third, if the grooves at the connectors are deepened and the L-shaped connectors are completely blocked, the strength of the wall panels at the connection will be reduced, and there is a risk of falling off in the later stage; fourth, the existing connectors generally require pre-set screws during factory processing and production, and the construction process is complicated, which reduces the factory's production efficiency.

[0019] In order to make the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the given embodiment is only one implementation method and does not represent all embodiments.

[0020] Combination Figure 1-Figure 5 The present embodiment provides a special connector for a composite thermal insulation exterior wall panel, the composite thermal insulation exterior wall panel comprises a wall panel body 3, the upper and lower ends of the wall panel body 3 are respectively connected to a main structure 2 through a special connector 1, the special connector 1 comprises a connecting plate 101 and a reinforcing rib 102, the two ends of one side of the connecting plate 101 are respectively connected to a first clamping plate 103 and a second clamping plate 104, the other side of the connecting plate 101 is fixed on the main structure 2, the connecting plate 101, the first clamping plate 103 and the second clamping plate 104 form a groove body, The reinforcing ribs 102 are respectively connected to the first clamping plate 103 and the connecting plate 101, and the second clamping plate 104 and the connecting plate 101, and the slot body is divided into two U-shaped slots by the reinforcing ribs 102; the front and rear surfaces of the upper and lower ends of both sides of the wall panel body 3 are concavely provided with snap-in slots 301, and the corresponding part of the wall panel body 3 provided with the snap-in slots 301 is the snap-in part, and the snap-in parts of the adjacent wall panel bodies 3 are snap-into the two U-shaped slots, respectively, and the first clamping plate 103 and the second clamping plate 104 are respectively placed in the snap-in slots 301 on the front and rear surfaces of the wall panel body 3. In this embodiment, the special connector 1 of the slot body is formed by the connecting plate 101, the first clamping plate 103 and the second clamping plate 104, one end of which is connected to the main structure 2, and the other end can be snap-into the snap-in part of the adjacent wall panel body 3 through two U-shaped slots, so as to realize the fixed connection between the composite thermal insulation exterior wall panel and the main structure 2.

[0021] Specifically, the main structure 2 includes a steel structure or a reinforced concrete structure, the steel structure is welded to the connecting plate 101, and the reinforced concrete structure is connected to the connecting plate 101 by at least two expansion bolts. As a preferred solution, when the special connector 1 needs to be connected by expansion bolts, the connecting plate 101 is provided with bolt holes 105 that match the expansion bolts to facilitate construction. In order to ensure the stability of the connection, after the nut of the expansion bolt is tightened, the expansion bolt needs to be welded to the connecting plate 101 to further strengthen the connection between the special connector 1 and the expansion bolt.

[0022] On the other hand, the reinforcing ribs 102 and the bolt holes 105 are preferably located on the center line of the special connector 1, so that the left and right U-shaped grooves can reach the optimal size at the same time, which is beneficial to the stability of the wall panel bodies 3 on the left and right sides.

[0023] In this embodiment, the concave depth of the snap-in groove 301 is greater than or equal to the thickness of the first clip plate 103 and the second clip plate 104, which is conducive to hiding the first clip plate 103 and the second clip plate 104 into the wall, improving the aesthetics of the wall and facilitating later use.

[0024] In this embodiment, the reinforcing ribs 102 include two triangular reinforcing ribs 102 arranged opposite to each other, and the two triangular reinforcing ribs 102 are respectively placed between the first clamping plate 103 and the connecting plate 101, and between the second clamping plate 104 and the connecting plate 101. The reinforcing ribs 102 increase the strength of the first clamping plate 103 and the second clamping plate 104 on the one hand, and limit the lateral displacement of the exterior wall panel on the other hand. Simplifying the reinforcing ribs 102 into two triangles arranged opposite to each other not only achieves strength and limits displacement, but also saves materials and reduces the weight of the structural parts. It should be understood that the special connector 1 of the wall panel body 3 at the end of a section of the building wall can be shortened to only have one U-shaped groove, and only the last wall panel body 3 is clamped.

[0025] In this embodiment, in order to ensure the stability and strength of the clip-on wall panel body 3, after many tests, the lengths of the first clip plate 103 and the second clip plate 104 are not less than 80 mm.

[0026] Preferably, the special connector 1 is made of galvanized steel plate, which has excellent corrosion resistance, mechanical properties, and processing properties and is suitable as a material for the connector.

[0027] When in use, first clamp the two special connecting parts 1 on the upper and lower ends of one side of the wall panel body 3 respectively, and then connect one of the wall panel bodies 3 with the upper and lower main structures 2 through the special connecting part 1 thereon, and then push the other wall panel body 3 clamped with the special connecting part 1 from one side of the fixed wall panel body 3 into the U-shaped groove of the fixed special connecting part 1, and then connect the wall panel body 3 with the upper and lower main structures 2 through the special connecting part 1 thereon, so as to realize the clamping of adjacent wall panel bodies 3 once, and repeat the above operation multiple times to realize the connection of multiple wall panel bodies 3 with the main structure 2.

[0028] The above is a detailed description of the specific implementation of the utility model in conjunction with the drawings, but the utility model is not limited to the described implementation. For those skilled in the art, without departing from the principle and spirit of the utility model, various changes, modifications, substitutions and variations are made to these implementations, which still fall within the scope of protection of the utility model.
