Description

Technical Field

[0001] The present application relates to the technical field of composite plate assembly structures, and in particular to an optimized structure of assembled building composite plates. Background Art

[0002] The reinforced concrete slabs used in China include cast-in-place slabs and precast slabs. Cast-in-place slabs have good integrity, but they require on-site formwork and then pouring concrete. The construction period is difficult, the formwork loss is large, and the cost is high. Precast slabs do not require on-site formwork, have a short construction period, and a low cost, but cracks are prone to occur at the joints of the components, and the integrity is poor, which affects the bidirectional force balance of the slab and makes it difficult to form an equivalent bidirectional slab.

[0003] The Chinese utility model patent with announcement number CN205530886U discloses an assembled composite slab, including a concrete slab and a lifting device. The left end surface of the concrete slab is provided with grooves, the right end of the concrete slab is provided with a protrusion, the upper end of the concrete slab is provided with a mounting plate, the mounting plate is arranged in contact with the upper end surface of the concrete slab, the vertical reinforcement ribs and the transverse reinforcement ribs are distributed inside the concrete slab, and the vertical reinforcement ribs and the transverse reinforcement ribs are arranged at an angle of 90°.

[0004] The above solution realizes the clamping connection of two concrete slabs through the design of grooves and protrusions. However, when the protrusions are clamped with the grooves, the protrusions need to move a long distance along the grooves, which makes the installation between the concrete slabs less convenient. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem that the existing composite plate structure realizes the clamping of two concrete plates through the design of grooves and protrusions. During the clamping, the protrusion needs to move a long distance along the groove, resulting in poor convenience when installing between the concrete plates.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An optimized structure of assembled building composite panels, including a prefabricated composite panel body with a reinforcement structure embedded inside, connection structures are provided on the side walls of the prefabricated composite panel body on both sides, the connection structure includes a connection hole with a trapezoidal cross-section opened on one side of the prefabricated composite panel body, a propping device is fixedly connected to the inner wall of the connection hole, and the connection structure also includes two groups of symmetrically arranged connection seats fixedly connected at both ends of the side wall of the other side of the prefabricated composite panel body, two connection seats in each group are provided with movable grooves on the side walls on the opposite side, a clamping block is rotatably connected inside the movable groove, and the two clamping blocks are provided with inclined surfaces with the same inclination angle as the inner wall of the connection hole on the side away from each other.

[0008] By adopting the above technical scheme, when using, the user first rotates the block connected by the pin in the inner cavity of the movable groove, so that the side of the block with the inclined surface is completely embedded in the movable groove, and then the user inserts the two sets of connecting seats installed on one of the prefabricated composite panel bodies into the connecting hole opened on the other prefabricated composite panel body. When the connecting seat is inserted, since the expansion block installed in the connecting hole is a triangular structure, it can push the block in the opposite direction through its side wall, so that the block rotates around the pin until the inclined surface of the block is tightly fitted with the inner walls on both sides of the connecting hole, thereby clamping the two prefabricated composite panel bodies together, and avoiding as much as possible the existing composite panel structure to achieve the clamping of two concrete panels through the design of grooves and protrusions. When clamping, the protrusion needs to move a long distance along the groove, resulting in poor convenience when installing between concrete panels.

[0009] Optionally, the reinforcement structure includes a plurality of longitudinal steel bars and a plurality of transverse steel bars embedded in the prefabricated composite panel body, and the longitudinal steel bars and the transverse steel bars are perpendicular to each other to form a grid structure.

[0010] By adopting the above technical solution, a reinforcement structure consisting of a grid structure composed of transverse steel bars and longitudinal steel bars is embedded in the prefabricated composite board body, which can greatly improve the supporting performance and compressive resistance of the prefabricated composite board body and make the prefabricated composite board body more stable.

[0011] Optionally, the propping device is an expansion block with one end fixedly connected to the inner wall of the connecting hole, and the end of the expansion block away from the inside of the connecting hole is a triangular plate structure, and the size of the expansion block is adapted to the size of the gap left between the two connecting seats in each group.

[0012] By adopting the above technical solution, after the connecting seat is inserted into the inner cavity of the connecting hole, the expansion block can be inserted into the gap between the two connecting seats in each group, thereby avoiding as much as possible the expansion block being blocked by the connecting seat and being unable to push the clamping blocks on both sides to rotate and clamp the prefabricated composite panel body.

[0013] Optionally, the clamping block is in the shape of a right-angled triangle, and a pin fixedly connected to the clamping block is provided on the acute-angle end of the clamping block, and both ends of the pin respectively penetrate the side walls of the movable groove and are rotatably connected to the side walls of the movable groove.

[0014] By adopting the above technical solution, the clamping block is set into a right-angled triangle structure, so that after the clamping block is rotated, its beveled edge can be inserted into the gap on both sides of the expansion block, tightly fit with the inner walls on both sides of the connecting hole, forming a clamping structure to fix the prefabricated composite board body.

[0015] Optionally, a bearing is sleeved at the connection between the pin and the connecting seat, the inner ring of the bearing is fixedly connected to the end of the pin, and the outer ring of the bearing is embedded in the connecting seat and fixedly connected to the connecting seat.

[0016] By adopting the above technical solution, a bearing is installed at the connection between the pin and the connecting seat to reduce the resistance when the pin drives the block to rotate. At the same time, it can minimize the rust at the connection between the pin and the connecting seat, which makes it difficult for the user to rotate the block.

[0017] Optionally, the connecting seat extends outward from one end close to the prefabricated composite board body to form a connecting plate embedded in the prefabricated composite board body. A through hole is provided on the connecting plate, and one of the longitudinal steel bars embedded in the prefabricated composite board body passes through the through hole and is welded to the connecting plate.

[0018] By adopting the above technical solution, a connecting plate is provided for pre-embedded inside the prefabricated composite panel body to fix the connecting seat, a through hole is opened on the connecting plate, and one of the longitudinal steel bars passes through the connecting plate through the through hole, thereby greatly improving the stability of the connection of the connecting plate and avoiding the problem of the connecting plate falling off from the inside of the prefabricated composite panel body after being subjected to external force.

[0019] In summary, the beneficial effects of this application are as follows:

[0020] The present application adopts the coordination setting between structures such as connecting holes, expansion blocks, connecting seats and clamping blocks. The clamping blocks are rotatably connected to the inner cavity of the movable groove opened on the connecting seat by means of pins. When the connecting seat is inserted into the connecting hole, the expansion blocks can squeeze the two clamping blocks in reverse to rotate, so that the inclined surfaces of the clamping blocks are tightly fitted with the inner walls on both sides of the connecting hole, and the two prefabricated composite panel bodies are clamped together. This avoids the problem that the existing composite panel structure realizes the clamping of two concrete panels through the design of grooves and protrusions. When clamping, the protrusion needs to move a long distance along the groove, resulting in poor convenience when installing between the concrete panels. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] See also Figure 1-3 An optimized structure of an assembled building composite panel includes a prefabricated composite panel body 1 with a reinforcement structure embedded inside. By embedding the reinforcement structure inside the prefabricated composite panel body 1, the compression resistance and support performance of the prefabricated composite panel body 1 can be greatly improved.

[0027] Connection structures are provided on the opposite side walls of the prefabricated composite panel body 1. When in use, the user can assemble and splice multiple prefabricated composite panel bodies 1 through the connection structures provided on both sides of the prefabricated composite panel body 1, so that the multiple prefabricated composite panel bodies 1 are connected to form a whole.

[0028] The connection structure includes a connection hole 4 with a trapezoidal cross-section opened on one side of the prefabricated composite board body 1. There are two connection holes 4, which are respectively located at the two ends of the prefabricated composite board body 1, and the inner walls of the two connection holes 4 are fixedly connected with a supporting device.

[0029] The connection structure also includes two groups of symmetrically arranged connecting seats 6 fixedly connected at both ends of the side wall of the other side of the prefabricated composite plate body 1. The two groups of connecting seats 6 are respectively aligned with the two connecting holes 4. The two groups of connecting seats 6 are respectively provided with movable grooves 7 on the side walls opposite to the two connecting seats 6 in each group. A clamping block 10 is rotatably connected inside the movable groove 7. The two clamping blocks 10 are provided with inclined surfaces 11 with the same inclination angle as the inner wall of the connecting hole 4 on the side away from each other.

[0030] Reference Figure 1 The reinforcement structure includes a plurality of longitudinal steel bars 2 and a plurality of transverse steel bars 3 embedded in the prefabricated composite panel body 1, and the longitudinal steel bars 2 and the transverse steel bars 3 are perpendicular to each other to form a grid structure. The reinforcement structure of the grid structure composed of the transverse steel bars 3 and the longitudinal steel bars 2 embedded in the prefabricated composite panel body 1 can greatly improve the support performance and compressive resistance of the prefabricated composite panel body 1, making the prefabricated composite panel body 1 more stable.

[0031] Reference Figure 3 The expansion device is an expansion block 5 fixedly connected to the inner wall of the connection hole 4 at one end, and the expansion block 5 is in a triangular plate-shaped structure at one end away from the inside of the connection hole 4. The size of the expansion block 5 is adapted to the size of the gap between the two connection seats 6 in each group. When the connection seat 6 is inserted into the inner cavity of the connection hole 4, the expansion block 5 can be inserted into the gap between the two connection seats 6 in each group, and the expansion block 5 is prevented from being blocked by the connection seat 6 as much as possible, and cannot push the clamping blocks 10 on both sides to rotate and clamp the prefabricated composite board body 1.

[0032] Reference Figure 2The block 10 is in a right-angled triangle structure, and a pin 12 fixedly connected to the block 10 is provided on the acute end of the block 10. Both ends of the pin 12 respectively penetrate the side walls of the movable groove 7 and are rotatably connected to the side walls of the movable groove 7. The block 10 is set in a right-angled triangle structure, so that after the block 10 is rotated, its beveled edge can be inserted into the gap on both sides of the expansion block 5, and fit closely with the inner walls on both sides of the connection hole 4 to form a clamping structure, so as to fix the prefabricated composite board body 1.

[0033] Reference Figure 3 A bearing is sleeved at the connection between the pin 12 and the connection seat 6, the inner ring of the bearing is fixedly connected to the end of the pin 12, and the outer ring of the bearing is embedded in the connection seat 6 and fixedly connected to the connection seat 6. The bearing is installed at the connection between the pin 12 and the connection seat 6 to reduce the resistance when the pin 12 drives the block 10 to rotate, and at the same time, it can avoid the problem of rust at the connection between the pin 12 and the connection seat 6, which makes it difficult for the user to rotate the block 10.

[0034] Reference Figure 2 , one end of the connection seat 6 close to the prefabricated composite board body 1 extends outward to form a connection plate 8 embedded in the prefabricated composite board body 1, and a through hole 9 is provided on the connection plate 8. One of the longitudinal steel bars 2 embedded in the prefabricated composite board body 1 passes through the connection plate 8 through the through hole 9 and is welded to the connection plate 8. The connection plate 8 is used to be embedded in the prefabricated composite board body 1 to fix the connection seat 6. The through hole 9 is provided on the connection plate 8, and one of the longitudinal steel bars 2 passes through the connection plate 8 through the through hole 9, which greatly improves the stability of the connection of the connection plate 8 and avoids the problem of the connection plate 8 falling off from the prefabricated composite board body 1 after being subjected to external force.

[0035] The implementation principle of the present application is as follows: when in use, the user first rotates the block 10 in the inner cavity of the movable groove 7 and is connected by the pin 12, so that the side of the block 10 with the inclined surface 11 is completely embedded in the movable groove 7, and then the user inserts the two sets of connecting seats 6 installed on one of the prefabricated composite board bodies 1 into the connecting hole 4 opened on the other prefabricated composite board body 1. When the connecting seat 6 is inserted, since the expansion block 5 installed in the connecting hole 4 is a triangular structure, it can push the block 10 in the opposite direction through its side wall, so that the block 10 rotates around the pin 12 until the inclined surface 11 of the block 10 is tightly fitted with the inner walls on both sides of the connecting hole 4, thereby clamping the two prefabricated composite board bodies 1 together, and avoiding as much as possible the existing composite board structure to realize the clamping of two concrete slabs through the design of grooves and protrusions. When clamping, the protrusion needs to move a long distance along the groove, resulting in poor convenience when installing between concrete slabs.
