[0002] A precast wall panel, also known as a precast concrete wall panel or a precast assembled wall panel, is a wall component prefabricated in a factory in advance. It is composed of concrete, steel bars and other materials, formed through a mold, and then transported to the site for installation;

[0003] A precast wall panel is an efficient, quality-controllable and resource-saving building component, widely used in various construction projects, including residential buildings, commercial buildings, public facilities, etc. It can provide a stable structure and rapid construction, bringing convenience and benefits to construction projects. When the precast wall panel is transported to the construction site, two precast wall panels are assembled through a connecting piece, and the conventional assembly method is mostly snap-in limit. The components on the connecting piece are inserted into the precast wall panel to complete the installation. However, the strength of the connection part of the precast wall panel completed by a single snap-in limit installation is relatively low, and the parts that are more likely to be damaged are mostly the connection points.

The limiting components include a fixing plate 300, a limiting plate 301, a clamping plate 302, a cover plate A 500, a knob cover 600, and a plug rod 602;

[0030] Symmetrical concrete pouring cavities 101 are provided inside the precast wall panel body 100 near both sides. Through grooves that are symmetrically arranged up and down are provided outside both sides of the precast wall panel body 100, and the through grooves communicate with the inside of the concrete pouring cavities 101. The concrete fully wraps the internal components in the concrete pouring cavities 101 to form cement columns. When the concrete solidifies, the structural strength reaches the maximum;

[0031] The number of fixing plates 300 on one side of the precast wall panel connector 200 is equal to the number of through grooves on one side of the precast wall panel body 100. The fixing plates 300 pass through the through grooves and are embedded inside the concrete pouring cavity 101. There is a limit plate 301 at each of the upper and lower ends of each fixing plate 300. The limit plate 301 is rotatably connected to the fixing plate 300, and there is an integrally fixed clamping plate 302 on the side of each limit plate 301;

[0032] There are multiple cover plates A500. The knob cover 600 is embedded inside the cover plate A500 and is rotatably connected to it.

[0034] Furthermore, there are integrally fixed connecting shafts A304 on both sides of the clamping plate 302. There are multiple integrally fixed connecting shafts B305 on the outer wall of the fixing plate 300. There are two pairs of springs 400 on both sides of the clamping plate 302. There are two integrally fixed gaskets 401 at the upper and lower ends of the spring 400. The two gaskets 401 are respectively sleeved on the outer sides of the connecting shaft A304 and the connecting shaft B305 and are rotatably connected to them.

[0035] Furthermore, a notch 303 is provided on each clamping plate 302. There are multiple integrally fixed limit blocks 603 on the outer side of the clamping plate 302. The width of the limit block 603 is equal to the width of the notch 303. The top of the limit block 603 is in contact with the bottom of the clamping plate 302.

[0036] Furthermore, there are multiple reinforcing rib plates 201 between the fixing plate 300 and the precast wall panel connector 200. The two ends of the reinforcing rib plate 201 are respectively fixedly connected to the fixing plate 300 and the precast wall panel connector 200. Compared with a single fixation, the reinforcement by multiple reinforcing rib plates 201 has higher strength. After installation, the precast wall panel has better seismic resistance and support, and the fixing plate 300 is parallel to the precast wall panel connector 200.

[0037] Furthermore, both sides of the precast wall panel connector 200 are provided with a plurality of integrally formed rib strips B203, and a plurality of external card slots 103 are opened on both sides of the precast wall panel body 100. The rib strips B203 are engaged with the external card slots 103 for clamping and limiting, so that the structure is sealed to avoid the phenomenon of concrete leakage, and after being sealed by this structure, air leakage of the wall panel can be avoided.

[0038] Furthermore, both sides of the precast wall panel connector 200 are provided with a plurality of integrally fixed rib strips A202, and symmetric secondary sealing grooves 105 are opened on both sides of the precast wall panel body 100. The rib strips A202 are engaged with the secondary sealing grooves 105 to seal the structure, avoid the phenomenon of concrete leakage, and after being sealed by this structure, air leakage of the wall panel can be avoided.

[0039] Furthermore, symmetric internal card slots 102 are opened at both ends of the through groove inside the concrete pouring cavity 101. The limiting plates 301 at both ends of the fixing plate 300 are embedded into the internal card slots 102 for clamping and limiting, so that the structure is sealed to avoid the phenomenon of concrete leakage, and after being sealed by this structure, air leakage of the wall panel can be avoided.

[0040] Further, bend the limiting plate 301 on the side of the precast wall panel connector 200 away from the precast wall panel connector 200, so that the spring 400 is compressed and shrinks. At this time, the fixing plate 300 and the limiting plate 301 can pass through the through groove and be embedded into the interior of the concrete pouring cavity 101. As the limiting plate 301 is embedded into the interior of the concrete pouring cavity 101, the spring 400 is no longer compressed, so that the spring 400 rebounds and pushes the clamping plate 302 and the limiting plate 301, making the limiting plate 301 tightly fitted inside the internal clamping groove 102. The fixing plates 300 and the limiting plates 301 on both sides of the precast wall panel connector 200 are embedded into the corresponding precast wall panel body 100 by this method. At this time, cover plate A 500 and cover plate B 501 are covered on the top of the precast wall panel body 100 and fitted with the top clamping groove 104, so that the insertion rod 602 is embedded downward into the interior of the concrete pouring cavity 101 and passes through a plurality of clamping plates 302. The limiting block 603 passes through the clamping plate 302 through the notch 303 and moves to the bottom of the clamping plate 302. At this time, rotate the dial block 601 by 180 degrees to drive the insertion rod 602 and the limiting block 603 to rotate, so that the limiting block 603 moves away from the notch 303 and completes the clamping with the clamping plate 302. At this time, pull the cover plate B 501 to rotate through the hinge 502 to open the concrete pouring cavity 101, and then pour concrete into the interior of the concrete pouring cavity 101. The concrete fully wraps the insertion rod 602 and the clamping plate 302 inside the concrete pouring cavity 101 to form a cement column. Then, cover plate B 501 is fitted with the top clamping groove 104 again and fixed by screws for sealing. When the concrete solidifies, the structural strength reaches the maximum, thus completing the assembly of the precast wall panel body 100. By this method, the precast wall panel body 100 can be expanded, and any number of precast wall panel bodies 100 can be installed.

[0041] Further, the precast wall panel structure installed in this way is more stable and has higher strength. After concrete pouring, multiple precast wall panel bodies 100 are combined into a whole, making its airtightness better and avoiding air leakage.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
