Description

Technical Field

[0001] This utility model relates to the field of exterior wall panel technology, and in particular to a prefabricated sandwich exterior wall panel. Background Technology

[0002] Precast sandwich wall panels are a type of prefabricated component widely used in modern architecture, named for their sandwich-like structure. These panels typically consist of three layers: an outer protective panel, a middle insulation layer, and an inner structural panel. They not only offer excellent thermal insulation performance but also significantly improve the overall quality of the building and construction efficiency.

[0003] However, in the existing technology, most sandwich wall panels require multiple bolts or screws for installation, which is time-consuming and labor-intensive, thus increasing the workload and cost. Moreover, the joints of sandwich wall panels are usually sealed with sealant or sealing strips, but long-term exposure to wind and sun can cause them to age and fall off, resulting in water seepage at the joints and reducing the service life of the sandwich wall panels. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where most sandwich wall panels require multiple bolts or screws for fixing during installation, which is time-consuming and labor-intensive, thus increasing the workload and cost. Moreover, the joints of sandwich wall panels are usually sealed with sealant or sealing strips, but long-term exposure to wind and sun can cause them to age and fall off, resulting in water seepage at the joints and reducing the service life of the sandwich wall panels.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated sandwich exterior wall panel, comprising: a first exterior wall panel and a second exterior wall panel, and further comprising:

[0008] Both slots are located on the side of the first outer wall panel away from the T-shaped groove, and the two slots are symmetrical to each other;

[0009] A sealing assembly is disposed on the outer surface of the first and second outer wall panels.

[0010] Preferably, the connection component further includes:

[0011] Both positioning rods are fixedly installed inside the two slots;

[0012] Two positioning blocks are fixedly installed on the side of the second outer wall panel away from the T-shaped groove. The two positioning blocks are symmetrical to each other and are movably installed inside the slot.

[0013] The I-beam plate is movably disposed inside the two T-shaped slots.

[0014] The technical effect of adopting the above-mentioned further solution is that after the first and second outer wall panels are spliced ​​together, the I-beam is embedded in the interior of the two T-shaped grooves, and then the bolt is embedded in the interior of the through hole so that one end of the thread is installed in the interior of the mounting hole. In this way, the I-beam can be more stably embedded in the interior of the T-shaped groove, reducing the number of bolts used to connect the first and second outer wall panels, thus saving materials and manpower.

[0015] Preferably, the sealing assembly includes:

This can improve the stability of the sealing plate, making it more stably embedded inside the sealing groove, sealing the joint between the first and second outer wall panels, and preventing water seepage.

[0021] Preferably, limit blocks are fixedly provided on both sides of the bottom of the sealing plate, and the limit blocks are movably disposed inside the limit groove.

[0022] The technical effect of adopting the above-mentioned further solution is that the limiting blocks on both sides of the bottom of the sealing plate are embedded in the limiting groove, which can improve the stability of the sealing plate.

[0023] Preferably, the outer surface of the I-beam has two circular grooves, which are symmetrical to each other.

[0024] The technical effect of adopting the above-mentioned further solution is that the other end of the bolt is embedded in the inside of the circular groove, preventing the bolt from protruding and affecting the appearance.

[0025] Preferably, both of the circular grooves have through holes inside, and bolts are movably installed inside the through holes.

[0026] The technical effect of adopting the above-mentioned further solution is that the bolt is embedded in the inside of the through hole so that one end of the thread is installed inside the mounting hole, so that the I-beam plate can be more stably embedded in the inside of the T-slot.

[0027] Preferably, both positioning blocks have circular holes on their outer surfaces, and the positioning rod is movably disposed inside the circular holes.

[0028] The technical effect of adopting the above-mentioned further solution is that the positioning block is sleeved on the outer surface of the positioning rod through the round hole, and the positioning rod can improve the stability of the positioning block, so that it will not shake inside the slot.

[0029] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0030] 1. In this utility model, two positioning blocks are fitted onto the outer surface of the positioning rod through round holes. The positioning rod can improve the stability of the positioning blocks, preventing them from shaking inside the slot. The positioning blocks are embedded inside the slot, connecting the first and second outer wall panels, which can improve the connection effect between the first and second outer wall panels. After the first and second outer wall panels are spliced, the I-beam is embedded inside the two T-shaped slots, and then the bolt is embedded inside the through hole so that one end is threaded and installed inside the mounting hole. In this way, the I-beam can be more stably embedded inside the T-shaped slot, reducing the number of bolts used to connect the first and second outer wall panels, thus saving materials and manpower. The other end of the bolt is embedded inside the round slot to prevent the bolt from protruding and affecting the appearance.

[0031] 2. In this utility model, while the I-beam is embedded in the T-groove, the sealing plate is embedded inside the sealing groove. The limiting blocks on both sides of the bottom of the sealing plate are embedded inside the limiting groove, which can improve the stability of the sealing plate and make it more stably embedded inside the sealing groove. This seals the joint between the first and second outer wall panels to prevent water seepage. A sealing strip is fixedly installed on the outer surface of the sealing plate.
