[0014] Beneficial effects

[0015] The utility model provides a noise reduction and sound insulation type assembled concrete steel bar truss floor bearing plate. Compared with the prior art, the following beneficial effects are achieved:

[0016] This noise-reducing and sound-insulating prefabricated concrete steel bar truss floor slab moves the second floor slab to the top of the first floor slab by moving the first limiting plate along the groove opened on the limiting frame. At this time, when transporting the second floor slab and the first floor slab, the stress area of the lifting rope can be effectively reduced, and the stability of the transportation can be improved. When transported to the designated location, the second floor slab is moved outwards through the provided groove, so that the positioning groove is stuck on the surface of the second limiting plate, and the second floor slab and the first floor slab are in a flat state. At this time, the steel bar truss main body is inserted into the L-shaped frame to complete the assembly of the steel bar truss main body. When fixing the steel bar truss main body, since the provided spring pulls the support frame upwards, the second limiting tooth plate and the first limiting tooth plate are engaged. Since the support frame is in a fixed state, the first limiting tooth plate is synchronously in a fixed state. At this time, the nut cannot rotate, and the fixing of the nut is completed. By rotating the screw, the fixing of the second floor slab, the first floor slab and the steel bar truss main body is completed. When the screw moves downwards, it will push the support frame to move downwards along the limiting groove, so that the second limiting tooth plate and the first limiting tooth plate are disengaged from the limit. When the screw rotates, the nut rotates synchronously, which can prevent the screw from loosening and falling off. Through the self-locking of the self-locking component, the rapid assembly of the workpiece is realized, and the assembly efficiency of the workpiece is improved. Description of the Drawings

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution, specifically including the following embodiments:

[0024] Embodiment 1:

[0025] A noise-reducing and sound-insulating prefabricated concrete steel bar truss floor slab, including a first floor slab 3. Both the left and right sides of the first floor slab 3 are fixedly connected with limiting frames 4. A first limiting plate 8 is slidably connected inside the limiting frame 4. A second floor slab 1 is fixedly connected to the outer surface of the first limiting plate 8. An L-shaped frame 2 is fixedly connected to the top of the second floor slab 1. A steel bar truss main body 9 is slidably connected inside the L-shaped frame 2. A bearing ring 11 is movably connected to the inside of the second floor slab 1 through a bearing. A self-locking assembly 5 is fixedly connected to the bottom of the bearing ring 11;

[0026] The self-locking assembly 5 includes a nut 501. A support ring 502 is fixedly connected to the bottom of the nut 501. First limiting tooth plates 503 are fixedly connected to both the front and rear sides of the bottom of the support ring 502. A spring 505 is fixedly connected to the bottom of the support ring 502. A support frame 506 is fixedly connected to the bottom of the spring 505. Second limiting tooth plates 504 are fixedly connected to both the front and rear sides of the top of the support frame 506. The bottom of the first limiting tooth plate 503 meshes with the top of the second limiting tooth plate 504;

[0027] By moving the second floor formwork 1 to the top of the first floor formwork 3 along the groove provided on the limit frame 4, when transporting the second floor formwork 1 and the first floor formwork 3 at this time, the stress area of the lifting rope can be effectively reduced, and the stability of the transportation can be improved. When transported to the designated location, through the provided groove, the second floor formwork 1 is moved outwards, so that the positioning groove 7 is stuck on the surface of the second limit plate 6, making the second floor formwork 1 and the first floor formwork 3 in a flat state. At this time, the steel bar truss main body 9 is inserted into the L-shaped frame 2 to complete the assembly of the steel bar truss main body 9. When fixing the steel bar truss main body 9, since the provided spring 505 pulls the support frame 506 upwards, the second limit tooth plate 504 and the first limit tooth plate 503 are engaged. Since the support frame 506 is in a fixed state, the first limit tooth plate 503 is synchronously in a fixed state. At this time, the nut 501 cannot rotate, and the fixing of the nut 501 is completed. By rotating the screw 10, the fixing of the second floor formwork 1, the first floor formwork 3 and the steel bar truss main body 9 is completed. When the screw 10 moves downwards, it will push the support frame 506 to move downwards along the limit groove 12, so that the second limit tooth plate 504 and the first limit tooth plate 503 are disengaged from the limit, so that when the screw 10 rotates, the nut 501 rotates synchronously, which can prevent the screw 10 from loosening and falling off. Through the self-locking of the self-locking component 5, the rapid assembly of the workpiece is realized, and the assembly efficiency of the workpiece is improved.

[0028] A limit groove 12 is provided in the inner cavity of the second floor formwork 1, and the surface of the limit groove 12 is slidably connected to the surface of the support frame 506;

[0029] When the provided screw 10 moves downwards, it will push the support frame 506 to move downwards along the limit groove 12, so that the second limit tooth plate 504 and the first limit tooth plate 503 are disengaged from the limit.

[0030] The inner cavity of the nut 501 is threadedly connected with a screw 10, and the surface of the screw 10 is slidably connected to the inner cavities of the L-shaped frame 2, the steel bar truss main body 9 and the second floor formwork 1;

[0031] By rotating the screw 10, the fixing of the second floor formwork 1, the first floor formwork 3 and the steel bar truss main body 9 is completed.

[0032] The number of L-shaped frames 2 is four. Two L-shaped frames 2 are a group, and the two L-shaped frames 2 are symmetrically distributed left and right. The two groups of L-shaped frames 2 are distributed in a linear array;

[0033] Through the provided two groups of L-shaped frames 2, the assembly of the two groups of steel bar truss main bodies 9 is carried out.

[0034] A positioning groove 7 is provided at the top of the second floor formwork 1, the surface of the inner side of the two limit frames 4 is fixedly connected with a second limit plate 6, and the surface of the second limit plate 6 is movably inserted into the inner cavity of the positioning groove 7;

[0035] Through the provided slots, the second floor formwork 1 is moved outwards, causing the positioning slot 7 to be stuck on the surface of the second limiting plate 6, making the second floor formwork 1 and the first floor formwork 3 in a flat state.

[0036] The number of the steel bar truss bodies 9 is two groups, and the two groups of steel bar truss bodies 9 are symmetrically distributed left and right.

[0037] The materials of both the second floor formwork 1 and the first floor formwork 3 are iron;

[0038] By setting that the materials of both the second floor formwork 1 and the first floor formwork 3 are iron, while improving the strength of the floor formwork, the sound insulation and noise reduction ability of the floor formwork is improved.

[0039] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0040] During operation, when it is necessary to transfer the second floor formwork 1 and the first floor formwork 3, first move the first limiting plate 8 along the slot provided on the limiting frame 4 to move the second floor formwork 1 to the top of the first floor formwork 3. At this time, when transferring the second floor formwork 1 and the first floor formwork 3, the stress area of the lifting rope can be effectively reduced, improving the stability of the transfer. When transferred to the designated location, through the provided slots, the second floor formwork 1 is moved outwards, causing the positioning slot 7 to be stuck on the surface of the second limiting plate 6, making the second floor formwork 1 and the first floor formwork 3 in a flat state. At this time, insert the steel bar truss body 9 into the L-shaped frame 2 to complete the assembly of the steel bar truss body 9. When fixing the steel bar truss body 9, since the provided spring 505 pulls the support frame 506 upwards, the second limiting tooth plate 504 and the first limiting tooth plate 503 are engaged. Since the support frame 506 is in a fixed state, the first limiting tooth plate 503 is synchronously in a fixed state. At this time, the nut 501 cannot rotate, completing the fixation of the nut 501. By rotating the screw 10, the fixation of the second floor formwork 1, the first floor formwork 3 and the steel bar truss body 9 is completed. When the screw 10 moves downwards, it will push the support frame 506 to move downwards along the limiting slot 12, causing the second limiting tooth plate 504 and the first limiting tooth plate 503 to be disengaged from the limit, so that when the screw 10 rotates, the nut 501 rotates synchronously, which can prevent the screw 10 from loosening and falling off. Through the self-locking of the self-locking component 5, the rapid assembly of the workpiece is realized, improving the assembly efficiency of the workpiece.
