Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. These buildings adopt standardized design, factory production, assembly construction, information management, and intelligent applications, and are representatives of modern industrialized production methods. The characteristics of prefabricated buildings include energy saving, environmental protection, and short construction period. Since the components are produced in factories, the material loss and environmental pollution of on-site construction can be reduced. At the same time, due to the high production efficiency, the construction period can be shortened.

[0015] A method for connecting a floor connection structure for an assembled building, the method comprising the following steps:

[0016] A. First, use a crane to lift the main body of the floor to be installed, so that the main body of the floor can be above the wall. Then, slowly lower the main body of the floor by the crane, and ensure that the positioning seat can be inserted into the positioning hole on the wall during the lowering process of the main body of the floor, so as to perform preliminary positioning between the main body of the floor and the wall;

[0017] B. Secondly, when the main body of the floor slab and the positioning seat continue to descend, the bottom of the vertical rod can be in contact with the bottom of the positioning hole in advance, and when the main body of the floor slab and the positioning seat continue to descend, the vertical rod can push the moving plate and the guide block to move, and compress the third spring at the bottom of the injection plate, so that the third spring can accumulate tension between the moving plate and the injection plate;

[0018] C. Then, when the bottom of the floor slab body contacts the wall, it indicates that it has reached the installation position. At the same time, the guide block can contact the surface of the rotating wheel under the action of movement, and push the rotating wheel and the U-shaped moving rod to move through the inclined surface, so that the U-shaped moving rod can be separated from the surface of the pin hole under the action of movement, and the limit on both sides of the injection plate can be released;

[0019] D. Then, under the push of the accumulated tension of the third spring, the glue injection disk can be pushed upward, and the sealant pre-injected inside the positioning seat and on the top of the glue injection disk can be pushed, so that the sealant can pass through the guide tube into the guide tube, and push the limit plug rod to move to the left and be inserted into the plug hole on the wall, so that the floor body and the wall can be effectively locked and limited, so as to achieve the purpose of rapid installation between the floor body and the wall;

[0020] E. At the same time, during the movement of the limit rod, it can detach from the bottom of the glue injection tube, causing the seal at the bottom of the glue injection tube to disappear, so that the sealant in the inner cavity of the guide tube can be transported to the inside of the glue guide groove through the glue injection tube. Under the action of continuous transportation of the sealant, the joint between the floor main body and the wall can be effectively filled through the glue guide groove.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can position the floor slab body and the wall during the hoisting process by setting the positioning seat and the positioning hole, so as to prevent the floor slab body and the wall from being misaligned during the installation process. Moreover, by setting the vertical rod, the movable plate, the guide block, the glue injection plate and the third spring, in the process of splicing the floor slab body and the positioning seat with the wall and the positioning hole, the third spring can accumulate tension between the movable plate and the glue injection plate, so as to provide assistance for the subsequent sealing glue injection and installation operations between the floor slab body and the wall. Moreover, when the floor slab body and the wall are connected in place, the limit of the glue injection plate can be released under the cooperation of the guide block, the rotating wheel, the U-shaped movable rod and the pin hole, and the third spring tension can be used to release the limit of the glue injection plate. Under the action of , the glue injection disc can be driven to move, and the sealant is injected into the inside of the guide tube through the guide tube under the push of the glue injection disc, and the limit plug rod is simultaneously pushed to be inserted into the inside of the insertion hole, so that the floor main body and the wall can be effectively locked and limited, so as to achieve the purpose of rapid installation between the floor main body and the wall, and when the limit plug rod is inserted into the inside of the insertion hole, the seal at the bottom of the glue injection tube disappears, and then the sealant can be injected into the gap between the floor main body and the wall through the glue injection tube and the glue guide groove, so that the joint between the floor main body and the wall can be effectively filled and sealed, avoiding rainwater leakage between the floor main body and the wall, and improving the overall waterproof and moisture-proof performance.

[0023] 2. The present invention provides the accommodating groove, the locking block, the first spring and the locking groove. When the limit rod is pushed by the pressure of the sealant, it can be inserted into the inside of the socket. When the limit rod moves, it can contact the surface of the locking block and push the locking block upward along the inclined surface. When the first spring is compressed, the support at the bottom of the locking block disappears until the locking groove is under the locking block. When the tension of the first spring is pushed, the locking block can be inserted into the inside of the locking groove. The limit rod can be effectively locked and limited, and the stability of the connection between the limit rod and the socket is effectively improved. The guide block is provided to guide the locking groove and the limit rod, so as to prevent the limit rod and the locking groove from rotating during the movement.

[0024] 3. The present invention provides a limiting groove, a receiving hole, a limiting convex rod and a second spring. Under the push of the second spring tension, the limiting convex rod can contact the surface of the limiting groove, thereby limiting the limit rod and the guide tube, preventing the limiting rod from sliding along the inside of the guide tube during the hoisting of the floor body. During the glue injection operation, the limiting rod is pushed by the sealant pressure, so that the limiting convex rod can be displaced upward and the second spring can be compressed until the limiting convex rod can be detached from the surface of the limiting groove, thereby releasing the limit of the limiting rod, so that the limiting rod can be inserted into the inside of the jack under the action of movement, thereby achieving the purpose of limiting the installation of the floor body.

[0025] 4. The present invention effectively improves the sealing of the contact between the limit plug rod and the guide tube through the provision of the first sealing ring, and avoids glue leakage between the limit plug rod and the guide tube. Through the provision of the second sealing ring, the sealing of the contact between the glue injection disk and the positioning seat is effectively improved, and glue leakage between the glue injection disk and the positioning seat is avoided. Through the provision of the guide slide bar, the purpose of guiding the movable disk is achieved, and the movable disk is prevented from tilting during the movement. Through the provision of the accommodating groove, the fourth spring and the guide cross bar, the purpose of guiding and supporting the U-shaped movable rod is achieved, and the U-shaped movable rod is prevented from tilting during the movement.

10. A method for connecting a floor connection structure for a prefabricated building according to any one of claims 1 to 9, characterized in that: The connection method comprises the following steps: A. First, the floor slab body (1) to be installed is lifted by a crane so that the floor slab body (1) is located above the wall (2). The floor slab body (1) is then slowly lowered by the crane, ensuring that the positioning seat (5) can be inserted into the positioning hole (3) on the wall (2) during the lowering of the floor slab body (1), thereby enabling preliminary positioning between the floor slab body (1) and the wall (2); B. Secondly, while the floor slab body (1) and the positioning seat (5) continue to descend, the bottom of the vertical rod (4) can be in contact with the bottom of the positioning hole (3) in advance, and while the floor slab body (1) and the positioning seat (5) continue to descend, the vertical rod (4) can push the movable plate (25) and the guide block (34) to move, thereby compressing the third spring (26) at the bottom of the glue injection plate (29), so that the third spring (26) can accumulate tension between the movable plate (25) and the glue injection plate (29); C. Subsequently, when the bottom of the floor slab body (1) contacts the wall (2), indicating that the installation position has been reached, at the same time, the guide block (34) can contact the surface of the rotating wheel (33) under the action of movement, and push the rotating wheel (33) and the U-shaped moving rod (36) to move through the inclined surface, so that the U-shaped moving rod (36) can be separated from the surface of the pin hole (35) under the action of movement, and the limit on both sides of the injection plate (29) can be released; D. Then, under the push of the accumulated tension of the third spring (26), the glue injection disk (29) can be pushed to move upward, and the sealant pre-injected inside the positioning seat (5) and located on the top of the glue injection disk (29) can be pushed, so that the sealant can pass through the guide tube (17) into the inside of the guide tube (11), and push the limit plug rod (12) to move to the left side so that it can be inserted into the plug hole (13) on the wall (2), so that the floor slab body (1) and the wall (2) can be effectively locked and limited, so as to achieve the purpose of rapid installation between the floor slab body (1) and the wall (2); E. At the same time, during the movement of the limit rod (12), it can be detached from the bottom of the glue injection tube (10), causing the seal at the bottom of the glue injection tube (10) to disappear, so that the sealant in the inner cavity of the guide tube (11) can be transported to the inside of the glue guide groove (6) through the glue injection tube (10). Under the action of the continuous transportation of the sealant, the joint between the floor slab body (1) and the wall (2) can be effectively filled through the glue guide groove (6).
