Abstract

The present invention discloses an assembled lightweight sandwich reinforced concrete roof slab and integral finish structure, including a roof slab. A precast concrete roof slab is fixedly connected to the upper surface of the roof slab. A finish is integrally formed on the lower surface of the roof slab. First flanges are symmetrically integrally formed on the front surface, rear surface and both side surfaces of the roof slab. A flow channel is formed on the upper surface of the roof slab. Through the mutual cooperation of four groups of flanges and concave grooves, the precast concrete roof slab and the roof slab can be quickly leveled, solving the cumbersome tool matching steps. Through the cooperation of the caliper and the convex column, and the spring catch and the fixed housing, after the staff inserts the roof slab into the precast concrete roof slab and aligns them, it can be clamped to form a reverse stroke self-locking ability. And the wet fire clay can provide temporary fixation at regular intervals. During this period, cement can be directly injected into the flow channel for sealing, solving the cumbersome steps that require multiple workers to support and cooperate in the previous installation process, and achieving precise leveling.

[0029] In this embodiment, specifically: a first concave groove 201 is formed on the inner side wall of the precast concrete roof slab 2, and the inner side wall of the first concave groove 201 is adapted to the first flange 102; through the mutual cooperation of the first concave groove 201 and the first flange 102, the roof slab 1 and the precast concrete roof slab 2 can be accurately, stably and levelly connected, avoiding the cumbersome steps of using a leveling tool in the traditional connection method and improving the work efficiency.

[0030] In this embodiment, specifically: a moisture-proof pad 3 is fixedly connected to the inner side wall of the flow channel 104; the moisture-proof pad 3 can prevent water vapor from seeping into the flow channel 104 and then entering the wall interior, causing erosion; the flow channel 104 is responsible for pouring cement into the interior after the roof slab 1 and the precast concrete roof slab 2 are installed.

[0031] In this embodiment, specifically: four second concave grooves 202 are symmetrically and integrally formed on both sides of the lower surface of the precast concrete roof slab 2, and the inner side wall of the second concave groove 202 is adapted to the first flange 102; through the mutual cooperation of the second concave groove 202 and the first flange 102, the roof slab 1 and the precast concrete roof slab 2 can be accurately, stably and levelly connected, avoiding the cumbersome steps of using a leveling tool in the traditional connection method and improving the work efficiency.

[0032] In this embodiment, specifically: on both sides of the lower surface of the precast concrete roof slab 2, two third concave grooves 203 are integrally formed symmetrically. The inner side walls of the third concave grooves 203 are adapted to the third flanges 501. Through the mutual cooperation of the third concave grooves 203 and the third flanges 501, the roof slab 1 and the precast concrete roof slab 2 can be accurately, stably and levelly connected, avoiding the cumbersome steps of using horizontal tools in the traditional connection method and improving the work efficiency.

[0033] In this embodiment, specifically: on both sides of the lower surface of the precast concrete roof slab 2, four fourth flanges 204 are integrally formed symmetrically. The outer surfaces of the fourth flanges 204 are adapted to the fourth concave grooves 502. Through the mutual cooperation of the fourth flanges 204 and the fourth concave grooves 502, the roof slab 1 and the precast concrete roof slab 2 can be accurately, stably and levelly connected, avoiding the cumbersome steps of using horizontal tools in the traditional connection method and improving the work efficiency.

[0034] In this embodiment, specifically: the inner side wall of the spring base 503 is coated with a spring sleeve 6, the inner side wall of the spring sleeve 6 is coated with a first spring 601, and a clamping block 602 is fixedly connected to the side surface of the first spring 601. When the roof slab 1 and the precast concrete roof slab 2 are installed, the clamping block 602 first contacts the fillet 701 of the fixed housing 7. Due to the pure curved surface characteristic of the fillet 701, when the clamping block 602 receives the pressure from it, it will be tangent to and compress the first spring 601 in an all-round way, and bring the clamping block 602 into the inside of the spring sleeve 6. When moving forward continuously, the clamping block 602 encounters a blind hole 702 above, and the pressure above disappears. The clamping block 602 bounces up under the action of the first spring 601 to lock the precast concrete roof slab 2, forming the ability of anti-travel self-locking.

[0035] In this embodiment, specifically: the upper surface of the base 4 is fixedly connected with a support housing 8. Two fixing grooves 801 are symmetrically opened on the upper surface of the support housing 8, and thirty-eight teeth 802 are symmetrically opened on the inner side walls of the fixing grooves 801. The fixing grooves 801 and the teeth 802 provide preconditions for the subsequent installation.

[0036] In this embodiment, specifically: two wet fire clay blocks 9 are fixedly connected to the lower surface of the fixed sleeve 205, and a vacuum coating 901 is coated on the outer surface of the wet fire clay blocks 9. The vacuum coating 901 can prevent the wet fire clay blocks 9 from coming into direct contact with the outside air in the non-installed state (such as during transportation) and causing expansion and curing failure. When the roof slab 1 and the precast concrete roof slab 2 are installed, the wet fire clay blocks 9 will be inserted into the fixing grooves 801. At this time, the teeth 802 will cut open the vacuum coating 901 so that the wet fire clay blocks 9 come into contact with the air and expand, temporarily fixing the precast concrete roof slab 2 and the roof slab 1, providing working conditions for the subsequent pouring of cement, and avoiding the cumbersome steps of multiple workers cooperating.

[0037] In this embodiment, specifically: Two support frames 10 are symmetrically and fixedly connected to the upper surface of the base 4. A caliper 1001 is integrally formed on the upper surface of the support frame 10. A second spring 1002 is fixedly connected to the inner side wall of the caliper 1001, and the outer surface of the second spring 1002 is adapted to the support frame 10. When the top plate 1 is installed with the precast concrete top plate 2, the caliper 1001 will elastically deform under the action of the second spring 1002 under the extrusion of the convex column 206. After the installation is completed, the caliper 1001 will lock the convex column 206, thereby locking the precast concrete top plate 2 and forming the ability of anti-stroke self-locking.

[0038] Working principle or structural principle: During the installation process, through the mutual cooperation of the first concave groove 201 and the first flange 102, the mutual cooperation of the second concave groove 202 and the first flange 102, the mutual cooperation of the third concave groove 203 and the third flange 501, and the mutual cooperation of the fourth flange 204 and the fourth concave groove 502, the top plate 1 and the precast concrete top plate 2 can be accurately, stably and levelly connected, avoiding the cumbersome steps of using horizontal tools in the traditional connection method and improving the work efficiency.

[0039] At the same time, when the top plate 1 is installed with the precast concrete top plate 2, the clamping block 602 first contacts the fillet 701 of the fixed housing 7. Due to the pure curved surface characteristic of the fillet 701, when the clamping block 602 receives the pressure from it, it will be tangent and compress the first spring 601 in all directions, and bring the clamping block 602 into the inside of the spring sleeve 6. When moving forward continuously, the clamping block 602 encounters the blind hole 702 above, and the pressure above disappears. The clamping block 602 bounces under the action of the first spring 601 to lock the precast concrete top plate 2. And at the same time, the caliper 1001 will elastically deform under the action of the second spring 1002 under the extrusion of the convex column 206. After the installation is completed, the caliper 1001 will lock the convex column 206, thereby locking the precast concrete top plate 2 and forming the ability of anti-stroke self-locking, solving the cumbersome steps that require multiple workers to support and cooperate in the past installation process, and accurately leveling.

[0040] At the same time, when the top plate 1 is installed with the precast concrete top plate 2, the wet fire clay block 9 will be inserted into the fixing groove 801. At this time, the pointed teeth 802 will cut open the vacuum coating 901 so that the wet fire clay block 9 contacts the air and expands, temporarily fixing the precast concrete top plate 2 and the top plate 1, providing working conditions for the subsequent pouring of cement. The flow channel 104 is responsible for pouring cement into the inside after the top plate 1 and the precast concrete top plate 2 are installed. At the same time, the moisture-proof pad 3 can prevent water vapor from infiltrating into the flow channel 104 and then into the wall body, causing erosion, and avoiding the cumbersome steps of multiple workers' cooperation.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
