Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete prefabricated parts, in particular to a prefabricated outer wall joint structure of assembled concrete building. BACKGROUND

[0002] The concrete prefabricated part, also known as PC component, is a concrete product processed and produced in a factory through standardization and mechanization, and the traditional cast-in-place concrete needs to be molded, poured and maintained on site.

[0003] When the joint of the concrete wall is treated, PE strips are usually filled inside, and then the joint is sealed. At this time, the reserved cavity is in a closed state. When the temperature difference is large, condensate water is easy to produce in the cavity, which can easily penetrate the wall and affect the service life of the wall. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies of the prior art, the prefabricated outer wall joint structure of assembled concrete building is provided, which has the advantages of improving practicality and solving the problems in the background art.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a prefabricated outer wall joint structure of assembled concrete building, comprising two wall bodies, a plurality of clamping grooves are formed on the side face of each wall body close to each other, a plurality of clamping pieces are arranged between the two wall bodies, the clamping pieces are located in the clamping grooves close to each other, two rubber sealing pieces are installed on the inner wall of each clamping groove, the rubber sealing pieces are in contact with the clamping pieces close to each other, a waterproof adhesive layer is installed on the side face of each wall body close to each other, and a communication pipe is installed on the outer surface of the wall body on the right side.

[0006] Through the above scheme, the waterproof performance of the two wall bodies can be improved by installing the waterproof adhesive layer, so as to avoid water vapor penetrating into the wall body.

[0007] Further, the side face of each waterproof adhesive layer close to each other is provided with a foam layer.

[0008] Through the above scheme, the foam layer installed between the two wall bodies can effectively block the propagation of air due to the excellent heat insulation performance of the foam material, so as to isolate the heat from the outside.

[0009] Further, a cavity is arranged between the two wall bodies, and a PE sealing strip is arranged in the cavity.

[0010] Through the above scheme, the PE sealing strip can seal the cavity and improve the waterproof performance of the joint of the wall body, so as to avoid the rainwater from the outside entering the cavity and affecting the use of the wall body.

[0011] Further, the inner wall of the plurality of card slots is provided with a rigid protrusion.

[0012] Through the above scheme, the installation of the rigid protrusion can push the clamping piece to extrude the rubber sealing piece when installing the wall, so that the rubber sealing piece can be tightly attached to the inner wall of the card slot.

[0013] Further, the outer surface of the plurality of clamping pieces is provided with a slot, and the plurality of rigid protrusions are located in the slot adjacent to the slot.

[0014] Through the above scheme, the slot can facilitate the contact between the clamping piece and the rigid protrusion, so that the tail of the clamping piece can be away from each other and extrude the rubber sealing piece, thereby improving the tight connection between the two walls.

[0015] Further, the plurality of clamping pieces are made of elastic material.

[0016] Through the above scheme, the clamping piece made of elastic material can be deformed to extrude the rubber sealing piece in the card slot, and the cooperation of the rubber sealing piece can increase the resistance between the clamping piece and the card slot, so that the two walls can be stably connected.

[0017] Further, the side surface of the two foam layers adjacent to each other is provided with an aerogel layer.

[0018] Through the above scheme, the aerogel has extremely low thermal conductivity and excellent heat insulation performance. When the aerogel layer is used on the building, it can significantly reduce the heat exchange between the indoor and outdoor, and keep the indoor temperature stable. Therefore, the aerogel layer can greatly reduce the energy consumption of indoor air conditioning and heating, and achieve the goal of energy saving and emission reduction.

[0019] Further, the right side surface of the right wall is provided with a plurality of bolts, and the plurality of bolts are threadedly connected through the right wall and the left wall.

[0020] Through the above scheme, the installation of the plurality of bolts can fix the two walls, so that the two walls can be tightly connected together, and the stability between the two walls is improved.

[0021] Compared with the prior art, the technical scheme of the present application has the following advantages:

[0022] The prefabricated concrete building prefabricated outer wall splicing joint structure can improve the waterproof performance of the two walls by installing the waterproof rubber layer, avoid water vapor penetrating into the wall, and make the cavity communicate with the outside through the installation of the communication pipe, so that the temperature in the cavity can be balanced with the outside, avoid the generation of condensed water in the cavity, thereby reducing the generation of condensed water in the cavity. At the same time, since the communication pipe is inclined downward, it can avoid the entry of external rainwater into the cavity. Attached Figure Description
