Description

Technical Field

[0001] The utility model relates to the technical field of building industry, in particular to a prefabricated concrete composite slab bottom plate connected with separated seams. Background Art

[0002] Definition of precast concrete composite slab bottom plate with separated joint connection: two adjacent precast concrete composite slab bottom plates in the prefabricated structure are placed side by side, separated from each other and need joint treatment between them. The traditional joint treatment method is to place additional longitudinal reinforcement on the joint of the precast bottom plate and pour concrete to form an integral load-bearing member.

[0003] For example, the public document with application number 202022011774.8 discloses a precast concrete composite slab base plate connected by separate joints. The utility model solves the problem of cracks and serious development at the separate joints of the prefabricated concrete composite slab base plate under load during use. Its improved structure will significantly improve the visual quality and performance of the building, which is conducive to the promotion of building industrialization. However, when splicing the precast concrete composite slab base plate connected by separate joints, the protruding columnar components need to be manually screwed one by one with nuts after insertion. A plurality of columnar components are provided on a precast base plate. Screwing them one by one will waste a lot of assembly time, which greatly affects the assembly efficiency, and it is difficult to ensure that the compressive force on different columnar components after the nuts are screwed remains the same, which results in slight differences in the forces at different points of the assembled base plate, affecting the assembly performance.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a precast concrete composite slab base plate with separated joint connections is proposed. Utility Model Content

[0005] The utility model aims to provide a prefabricated concrete composite slab bottom plate with separated joint connections to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precast concrete composite slab bottom plate connected with a separate joint, comprising a precast bottom plate, a plug-in mechanism is arranged on the left side of the precast bottom plate, five grooves are evenly distributed on the right side above the surface of the precast bottom plate, five plug-in holes are evenly distributed on the right side of the surface of the precast bottom plate, the plug-in holes are connected to the inside of the grooves, and a sealing member is sleeved on the surface of the plug-in mechanism.

[0007] Preferably, the plug-in mechanism comprises an insertion rod embedded and fixedly installed in the left inner wall of the prefabricated bottom plate, the left end of the insertion rod protrudes out of the prefabricated bottom plate, and the protruding length of the insertion rod matches the depth length of the groove and the insertion hole.

[0008] Preferably, the plug-in mechanism further comprises that both the front and rear sides of the surface of the plug rod are provided with convergence grooves, and both the upper and lower sides of the inner surface of the convergence groove are provided with limiting sliding grooves.

[0009] Preferably, the plug-in mechanism further comprises a sliding block slidably arranged on the inner surface of the limiting sliding groove, and the same movable block is fixedly mounted on the opposite end of the sliding block, and the left end of the movable block is arranged as an inclined surface.

[0010] Preferably, the plug-in mechanism further comprises a thrust spring fixedly mounted on one side of the movable block close to the inside of the convergence groove, and one end of the thrust spring is fixedly connected to the inner surface of the convergence groove.

[0011] Preferably, the sealing member comprises a reinforcing plate sleeved on the surface of the insertion rod, and asbestos mesh plates are fixedly mounted on both left and right sides of the surface of the reinforcing plate.

[0012] Preferably, the sealing member further comprises a through hole formed through the surfaces of the reinforcing plate and the asbestos mesh plate, and the reinforcing plate is sleeved on the surface of the insertion rod through the through hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a plug-in mechanism, a plug-in rod, a convergence groove, a limit slide groove, a slider, a movable block, a thrust spring, a groove and a socket. When two prefabricated bottom plates are assembled, one prefabricated bottom plate is inserted into the socket of another prefabricated bottom plate by using a plug-in rod. At this time, the inner wall of the socket will use an inclined surface to push the movable block to shrink into the convergence groove and squeeze the thrust spring. When the plug-in rod is fully inserted, the movable block is located inside the groove. At this time, the limit of the socket is lost, and the thrust spring will push the movable block to extend out of the convergence groove, and then the protrusion of the movable block will fit and buckle on the inner surface of the groove, so as to avoid the prefabricated bottom plates from being loosened, and the two prefabricated bottom plates in the same direction can be stably and tightly fit and spliced.

[0015] 2. The utility model arranges sealing parts, reinforcing plates, asbestos mesh plates and through holes. Before the prefabricated bottom plates are spliced, the reinforcing plates and the asbestos mesh plates are integrally sleeved on the surface of the plug-in rods through the through holes. Then the two prefabricated bottom plates are spliced. After the plug-in mechanism connects the two prefabricated bottom plates, the gap between the two prefabricated bottom plates is further sealed by the plate body composed of the reinforcing plates and the asbestos mesh plates, making the two prefabricated bottom plates more complete, improving the visual quality and performance of the building, and preventing the joints from being broken during the subsequent pouring of the upper concrete.

[0024] By adopting the above technical solution, one prefabricated base plate 1 can be stably and firmly assembled with another prefabricated base plate 1 by using the plug-in mechanism 2, the plug hole 4 and the groove 3.

[0025] Furthermore, the plug-in mechanism 2 includes an insertion rod 201 embedded and fixedly installed in the left inner wall of the prefabricated base plate 1, the left end of the insertion rod 201 protrudes from the prefabricated base plate 1, and the protruding length of the insertion rod 201 matches the depth length of the groove 3 and the insertion hole 4.

[0026] By adopting the above technical solution, the insertion rod 201 can be inserted into the insertion hole 4 and extend into the groove 3.

[0027] Furthermore, the plug-in mechanism 2 also includes a converging groove 202 formed on the front and rear sides of the surface of the plug rod 201 , and a limiting sliding groove 203 is formed on the upper and lower sides of the inner surface of the converging groove 202 .

[0028] By adopting the above technical solution, the converging groove 202 can accommodate the movable block 205 .

[0029] Furthermore, the plug-in mechanism 2 also includes a slider 204 slidably arranged on the inner surface of the limiting slide groove 203, and a movable block 205 is fixedly installed on the opposite end of the slider 204, and the left end of the movable block 205 is arranged as an inclined surface.

[0030] By adopting the above technical solution, the movable block 205 can be squeezed and retracted into the convergence groove 202 using the inclined surface, and the slider 204 cooperates with the limiting slide groove 203 to make the movement of the movable block 205 more stable and prevent the movable block 205 from protruding out of the convergence groove 202.

[0031] Furthermore, the plug-in mechanism 2 also includes a thrust spring 206 fixedly installed on one side of the movable block 205 close to the inner side of the convergence groove 202 , and one end of the thrust spring 206 is fixedly connected to the inner surface of the convergence groove 202 .

[0032] By adopting the above technical solution, the thrust spring 206 can push the movable block 205 to extend.

[0033] like Figure 1 and Figure 5 As shown, the sealing member 5 comprises a reinforcing plate 501 sleeved on the surface of the insert rod 201 , and asbestos mesh plates 502 are fixedly mounted on both left and right sides of the surface of the reinforcing plate 501 .

[0034] By adopting the above technical solution, the reinforcing plate 501 can improve the strength of the entire sealing member 5, and the asbestos mesh plate 502 can receive the concrete poured above in the gap to prevent the concrete from being lost.

[0035] Furthermore, the sealing member 5 further includes a through hole 503 penetrating through the surfaces of the reinforcing plate 501 and the asbestos mesh plate 502 , and the reinforcing plate 501 is sleeved on the surface of the insertion rod 201 through the through hole 503 .

[0037] Working principle: When using the prefabricated concrete composite slab bottom plate connected by the split joint, first, the plate body formed by the combination of the reinforcing plate 501 and the asbestos mesh plate 502 is sleeved on the surface of the insertion rod 201 through the through hole 503, and then, the prefabricated bottom plates 1 assembled in the same direction, when two prefabricated bottom plates 1 are assembled, one prefabricated bottom plate 1 is inserted into the insertion hole 4 of the other prefabricated bottom plate 1 by using the insertion rod 201, at this time, the inner wall of the insertion hole 4 will use the inclined surface to push the movable block 205 to shrink into the convergence groove 202, and squeeze the thrust spring 20 6. When the insertion rod 201 is fully inserted, the movable block 205 is located inside the groove 3. At this time, the limit of the insertion hole 4 is lost, and the thrust spring 206 will push the movable block 205 to extend out of the convergence groove 202, and then the movable block 205 protrudes and fits on the inner surface of the groove 3. At this time, the two prefabricated bottom plates 1 are stably and firmly assembled and fit, and the sealing member 5 at the joint is squeezed to make the joint tighter and make the two prefabricated bottom plates 1 more complete. This is the working principle of the prefabricated concrete composite slab bottom plate connected with the separate joint.
