Embodiment Construction

[0017] see figure 1 , figure 2 A prefabricated wallboard of the present invention comprises a wallboard body 1, one end of the wallboard body 1 has a tenon joint 11, the other end has a tenon groove 12, the end of the tenon joint 11 is provided with a sealing member 14, and the The seal 14 has a compressible cavity 140. After the ends of the two wall panel bodies 1 are spliced ​​together, the tenon joint 11 is inserted into the tenon groove 12, and the seal 14 and the tenon groove 12 are pressed tightly. In cooperation, the two ends of the wall panel body 1 are further provided with a joint groove 15 on one side close to the outer surface 101 , and a first sealing strip 151 is installed on the side wall of the joint groove 15 .

[0018] Further, see figure 2 , after the ends of the two wall panel bodies 1 are spliced ​​together, a seaming cavity 10 that can be used to install the seaming assembly 2 is formed at the seam groove 15, and the seaming assembly 2 is used to clos...

Abstract

The invention proposes a prefabricated wall panel and its waterproof joint structure. The waterproof joint structure includes a wall panel body, a joint assembly, a sealing block frame and a locking member. The joint assembly is installed on the two wall panel bodies. A seam cavity is formed after the ends of the seam are spliced ​​together, one side of the seam assembly is provided with a number of group clips, one side of the seam slot is provided with a limit installation part, and the side of the limit installation part is provided The wall is provided with a card slot matched with the card foot, and two limit card plates are symmetrically arranged on the side with the card foot on the seam assembly, and the limit card plate is snap-fitted with the limit groove , a plurality of locking pieces corresponding to each set of clips are installed on the seam assembly, the locking members are matched with the clips to prevent the clips from shrinking inward, and the seam assembly faces the outer surface of the One side has an opening, and the sealing baffle is installed on the opening of the seam assembly, which can avoid the phenomenon of water entering the seam, has a good waterproof effect, and can reduce the cracking phenomenon to a certain extent.

Description

【Technical field】 [0001] The invention relates to the technical field of prefabricated buildings, in particular to a prefabricated wall panel and its waterproof joint structure. 【Background technique】 [0002] Prefabricated buildings are buildings assembled on construction sites with prefabricated parts. The development of prefabricated buildings is a major change in construction methods. However, there is a seam of about 20mm between the prefabricated wall panel and the prefabricated wall panel of the prefabricated building. The seam is prone to water seepage, which seriously affects the product quality of the prefabricated building. Therefore, a prefabricated wall panel and its waterproof seam structure are proposed. . [Content of the invention] [0003] The purpose of the present invention is to solve the problems in the prior art, and to propose a prefabricated wall panel and its waterproof joint structure, which can avoid the phenomenon of water entering the joints, ...
