Description
Technical Field
Connecting structure of basement bottom plate
The utility model relates to a connecting structure of a basement bottom plate, in particular to a connecting structure of an overlong basement bottom plate, belonging to the innovative technology of the connecting structure of the basement bottom plate.
Background
After the building floor exceeds the structural length set by the specification, the tensile stress caused by temperature action, concrete shrinkage and the like is gradually accumulated, the floor is cracked, and expansion joints are required to be arranged. The expansion joint is arranged to disconnect the structure, the floor stress can be reset, but the sealing of the expansion joint is difficult to ensure for floors such as roofs, terraces, overhead gardens, basement roofs and basement floors which are directly contacted with soil and water, and the large hidden danger of water leakage exists.
Disclosure of Invention
The present invention has been made in view of the above problems, and an object of the present invention is to provide a connection structure for a basement floor. The utility model eliminates the expansion joint, thereby fundamentally avoiding the problem of water leakage.
The technical scheme of the utility model is as follows: the utility model relates to a connecting structure of a basement bottom plate, which comprises a first floor slab, a second floor slab, a first side wall, a second side wall, a bottom plate and a cover plate, wherein the first floor slab is connected with one end of the bottom plate through the first side wall, the second floor slab is connected with the other end of the bottom plate through the second side wall, the first floor slab, the second floor slab, the first side wall, the second side wall and the bottom plate are connected to form a concave structure, a post-pouring belt is arranged in the middle of the bottom plate, an advanced water stop belt is arranged at the lower part of the post-pouring belt, a water stop steel plate is arranged in the advanced water stop belt, the cover plate is arranged between the first floor slab and the second floor slab, one end of the cover plate is supported on a first groove formed in the first floor slab, and the other end of the cover plate is supported on a second groove formed in the second floor slab.
The utility model adopts the floor slab concave mode to obviously reduce the axial rigidity of the floor slab, effectively reduce the temperature stress and the shrinkage stress of the concrete, play a role similar to an expansion joint, ensure that the floor slab structure can not crack under the condition of not arranging the expansion joint, and because the concrete is continuously poured, the integral sealing is complete, the water leakage phenomenon can not occur, and the arrangement of the cover plate ensures that the floor slab surface is complete without influencing the use function of the building. The connecting structure of the basement bottom plate is ingenious in design, excellent in performance, convenient and practical.

Detailed Description
Example (b):
the structure of the utility model is schematically shown in fig. 1 and 2, the connecting structure of the basement bottom plate of the utility model comprises a first floor 1, a second floor 2, a first side wall 3, a second side wall 4, a bottom plate 5 and a cover plate 9, wherein the first floor slab 1 is connected with one end of a bottom plate 5 through a first side wall 3, the second floor slab 2 is connected with the other end of the bottom plate 5 through a second side wall 4, the first floor slab 1, the second floor slab 2, the first side wall 3, the second side wall 4 and the bottom plate 5 are connected to form a concave structure, and the middle part of the bottom plate 5 is provided with a post-pouring belt 6, the lower part of the post-pouring belt 6 is provided with an advanced water stop belt 7, a water stop steel plate 8 is arranged in the advanced water stop belt 7, a cover plate 9 is arranged between the first floor plate 1 and the second floor plate 2, one end of the cover plate 9 is supported on a first groove 11 arranged on the first floor plate 1, and the other end of the cover plate 9 is supported on a second groove 21 arranged on the second floor plate 2.
In this embodiment, the middle part of above-mentioned bottom plate 5 is at the regional ligature reinforcing bar of post-cast strip 6, and stagnant water steel sheet 8 inlays inside waterstop 7, and bottom plate 5 and leading waterstop 7 adopt concrete monolithic pouring to become an organic whole again.
In this embodiment, the first floor 1, the second floor 2, the first side wall 3, the second side wall 4, and the bottom plate 5 are integrally cast with concrete.
In this embodiment, the cover plate 9 is a prefabricated reinforced concrete plate.
In the present embodiment, the thickness of the first side wall 3 and the second side wall 4 is smaller than the thickness of the first floor slab 1 and the second floor slab 2.
The steel bar configurations of the first floor 1, the second floor 2, the first side wall 3, the second side wall 4 and the bottom plate 5 are determined according to stress calculation, and the steel bar connection structure meets the relevant regulations of the standard atlas 16G101 and is a continuous stress structural member.
When the utility model works, because the first floor slab 1, the second floor slab 2, the first side wall 3, the second side wall 4 and the bottom slab 5 are connected to form a concave structure, when the temperature stress and the concrete shrinkage stress reach a certain value, the first floor slab 1 and the second floor slab 2 are concave, the axial constraint of the first floor slab 1 and the second floor slab 2 is obviously reduced by the thinning structure of the first side wall 3 and the second side wall 4, and then the constraint is released by the multiple fold lines of the first side wall 3, the bottom slab 5 and the second side wall 4, because the thickness of the bottom slab of the whole basement is larger, the axial disconnection between the first floor slab 1 and the second floor slab 2 can not be completely realized by the concave mode, the post-cast strip 6 is arranged in the center of the bottom slab 5, and the advanced water stopping method is adopted, the stress can be further reduced, the first floor slab 1 and the second floor slab are further separated in the concrete age, the temperature stress and the shrinkage effect are reset, the whole basement bottom plate comprising the first floor slab 1, the second floor slab 2, the bottom plate 5 and the like is ensured not to crack.
