[0001] The utility model relates to the field of building construction, and more specifically, the utility model relates to a laminated slab connector for building construction. Background Technique

[0002] A laminated floor slab is an assembled monolithic floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. The laminated floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer. It is suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness.

[0003] After retrieval, the existing patent (application number: 202223228364.4) discloses a laminated slab connector for building construction.

A plurality of connecting rods are arranged on the laminated slab, and the connecting rods movably penetrate through the limit holes. A plurality of lugs are arranged on both sides of the connection plate, and a plurality of clamping grooves are arranged on the laminated slab. Each lug is clamped in the clamping groove and fixed by the limit component. The structure of the utility model is simple. The laminated slab can be quickly assembled through the connection plate. The probability of dislocation at the connection part of adjacent laminated slabs can be reduced through the connection plate. At the same time, the connection strength of adjacent laminated slabs is strengthened by the connector, and the practicability is strong.

[0004] The inventor found the following problems in the process of realizing the utility model in the prior art: Although the above technical solution can improve the assembly speed of the laminated slab through the connection plate, only relying on the locking bolts on the connection plate to fix the laminated slab, its stability cannot be guaranteed. The main reason is that: the locking bolts on the connection plate are prone to rotational loosening under the influence of external factors (external factors include: external vibration). Once loosened, the laminated slab will also loosen, and thus the stability between the laminated slabs cannot be guaranteed.

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "setting" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set.

[0026] As shown in the attached Figures 1-5 A laminated board connector for building construction, including a laminated board 1 and a connecting board 2. A positioning rod 20 is fixedly installed on the surface of the laminated board 1, and a positioning groove adapted to the positioning rod 20 is opened on the surface of the connecting board 2. By setting the connecting board 2, the positioning rod 20 and the positioning groove, the laminated board 1 can be quickly positioned by inserting the positioning rod 20 on the laminated board 1 into the positioning groove on the connecting board 2, so as to quickly complete the assembly of the laminated board 1, and the assembly speed of the laminated board 1 can be improved.

[0027] During specific use, first place the connecting board 2 in the middle position between two laminated boards 1, and then push the laminated board 1 to make the positioning rod 20 on the laminated board 1 enter the positioning groove on the connecting board 2, thus completing the positioning work.

[0028] A connecting mechanism is provided on the surface of the connecting board 2, and a groove board 3 is provided on the top of the laminated board 1. The connecting mechanism includes a fixing plate 4 fixedly installed on the upper surface of the connecting board 2. A bidirectional threaded rod 5 and a worm 6 are respectively rotatably connected to the inner wall of the fixing plate 4, and a moving block 7 is threadedly connected to the surface of the bidirectional threaded rod 5.

[0029] An L-shaped plate 8 is fixedly connected to the surface of the moving block 7, a worm gear 9 is fixedly connected to the surface of the bidirectional threaded rod 5, and a limiting mechanism is provided on the side surface of the fixing plate 4. The limiting mechanism includes a circular ring 10 fixedly installed on the side surface of the fixing plate 4.

[0030] A housing 17 is fixedly connected to the upper surface of the groove board 3, a compression spring 18 is fixedly connected to the inner wall of the housing 17, and a trapezoidal block 19 is fixedly connected to the lower end of the compression spring 18.

[0031] When using the connecting mechanism, after the laminated board 1 is positioned, by rotating the worm 6, the worm gear 9 rotates. At the same time, the worm gear 9 drives the bidirectional threaded rod 5 to rotate, and the bidirectional threaded rod 5 drives the two L-shaped plates 8 to move towards the middle, so that the L-shaped plates 8 enter the inside of the groove board 3 through the trapezoidal block 19. At this time, the trapezoidal block 19 will re-abut against the inner wall of the groove board 3 under the elastic force of the compression spring 18, and the trapezoidal block 19 can further limit the L-shaped plates 8, which can play a limiting role.

[0032] One end of the worm 6 extends to the inside of the circular ring 10 and is fixedly connected to the rotating shaft 11. The inner wall of the circular ring 10 is fixedly connected to a plurality of teeth 12 in a circular array. The inner wall of the rotating shaft 11 is fixedly connected to a compression spring 13. One end of the compression spring 13 is fixedly connected to a spur rack 14. A hook 15 is fixedly connected to the surface of the spur rack 14. The inner wall of the rotating shaft 11 is rotatably connected to a gear 16. A round rod is fixedly connected to the surface of the gear 16. The gear 16 meshes with the spur rack 14. A protective shell is clamped on the surface of the circular ring 10, and a handle is fixedly connected to the surface of the rotating shaft 11.

[0033] When using the limiting mechanism, when it is necessary to rotate the worm 6 by rotating the shaft 11, first rotate the round rod to drive the gear 16 to rotate. Since the gear 16 is meshed with the spur rack 14, the gear 16 will drive the spur rack 14 to move inward, so that the hook 15 on the spur rack 14 disengages from the teeth 12, so that the shaft 11 can be temporarily released from the restricted state. In this state, the construction personnel can rotate the worm 6 through the shaft 11. When the rotation is completed, release the round rod. At this time, the hook 15 on the spur rack 14 will press against the teeth 12 again under the action of the elastic force of the compression spring 13, so that the shaft 11 can be restored to the restricted state. Through this limiting mechanism, the connecting mechanism can be effectively limited to prevent it from loosening.

[0034] The composite plate connector for construction is provided with a connecting mechanism and a limiting mechanism. The connecting mechanism can be used to quickly assemble and fix the composite plates 1, while the limiting mechanism can limit the connecting mechanism to prevent the connecting mechanism from rotating, thereby avoiding looseness between the composite plates 1 and improving the stability of the assembly of the composite plates 1.

[0035] The working process of the utility model is as follows: when using the composite plate connector for construction, first put the connecting plate 2 in the middle position of the two composite plates 1, and then push the composite plate 1 so that the positioning rod 20 on the composite plate 1 enters the positioning groove on the connecting plate 2, thereby completing the positioning work. When the composite plate 1 is positioned, the worm gear 9 is rotated by rotating the worm 6, and the worm gear 9 drives the bidirectional threaded rod 5 to rotate, and the bidirectional threaded rod 5 drives the two L-shaped plates 8 to move toward the middle, thereby making the L-shaped plate 8 pass through the trapezoidal block 19 and enter the interior of the groove plate 3. At this time, the trapezoidal block 19 will press against the inner wall of the groove plate 3 again under the elastic force of the extrusion spring 18.

[0036] When the L-shaped plate 8 enters the groove plate 3, the round rod is loosened. At this time, the hook 15 on the spur rack 14 will press against the tooth 12 again under the elastic force of the compression spring 13, so that the rotating shaft 11 returns to the restricted state. Through this limiting mechanism, the connecting mechanism can be effectively limited to prevent it from loosening. This is the working principle of the composite plate connector for construction.
