Description
Technical Field
The utility model relates to a basement outer wall post-pouring strip advanced plugging structure.
Background
In the construction of the underground wall, harmful cracks possibly generated due to uneven temperature and shrinkage of a cast-in-situ reinforced concrete structure are prevented, and a post-cast strip is generally arranged on the outer wall of the basement according to about 30 m. The post-cast strip inevitably falls into sundries before being sealed, so that the cleaning is difficult, and rainwater and construction water easily enter a basement to influence normal construction; therefore, in order not to influence the normal construction of the waterproof and outdoor backfill of the outer wall, a unidirectional formwork is arranged on one side of the post-cast strip, wherein the formwork structure is as in patent number CN 203247838U, the fully-buried basement side wall post-cast strip advanced water stop formwork, expansion bolts are required to be vertically and alternately distributed on the wall to fix the lapping plate 3 (relative to the formwork) during implementation, the wall is firstly drilled with holes on the wall to bring adverse effects on the strength of the wall, and secondly, steel bars are generally arranged in the wall, the drilling construction difficulty is high, the quality is difficult to ensure, the expansion amount of the wall is directly applied to the expansion bolts and the lapping plate, and the lapping plate is easy to loosen or generate a large gap.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide the advanced plugging structure of the post-cast strip of the basement outer wall, which is used for solving the problems that single-sided formwork supporting is needed to be carried out on one indoor side of the post-cast strip, construction difficulty is high and quality is difficult to guarantee.
In order to solve the problems, the technical scheme of the utility model is as follows:
the basement outer wall post-pouring strip advanced plugging structure comprises reinforcing steel bars at a notch of an outer wall post-pouring strip, trapezoidal cover plates are covered outside the notch of the post-pouring strip, two ends of each cover plate are propped against outer walls at two sides of the notch, the cover plates are connected with the reinforcing steel bars through a plurality of connecting pieces, waterproof layers are covered outside the cover plates and the outer wall, and protective layers are arranged outside the waterproof layers.
The cover plate is composed of a plurality of trapezoid steel plates, a plurality of guide rail channel steel are welded on the steel plates, insertion pipes are fixedly connected in one ends of the guide rail channel steel, and one ends of the insertion pipes are exposed out of the steel plates.
The guide rail channel steel is internally provided with connecting pieces, each connecting piece comprises a sliding block assembled in the guide rail channel steel, a double-head screw rod is connected to the sliding block in a threaded mode, and a reinforcing steel bar hook and a threaded connection nut are sleeved on the double-head screw rod in an sleeved mode.
The two sides of the steel plate are provided with extension sections, and rubber sheets are fixedly connected to the extension sections in an adhering mode.
The waterproof layer is a waterproof coiled material of SBS modified asphalt, and the protective layer is an EPS molding polystyrene board.
The beneficial effects of the utility model are as follows: the cover plate can be conveniently and rapidly connected with the outer wall steel bars through the connecting piece, and the cover plate is not applied to the outer wall body, so that the plugging structure does not influence the outer wall expansion, and meanwhile, the post-pouring strip is good in plugging quality, strong in sealing performance, good in waterproof effect, and convenient and rapid to construct.
Drawings
The utility model is further described with reference to the accompanying drawings:
figure 1 is a schematic view of the structure of the present utility model,
figure 2 is a schematic diagram of the structure of the utility model in practice,
fig. 3 is a schematic top view of the present utility model.
In the figure: steel plate 1, guide rail channel steel 2, extension section 3, sheet rubber 4, reinforcing bar coupler 5, double-end screw rod 6, slider 7, reinforcing bar 8, outer wall 9, breach 10, waterproof layer 11, protective layer 12, intubate 13.
Detailed Description
As shown in fig. 1 to 3, the basement outer wall post-pouring strip advanced plugging structure comprises a steel bar 8 at a notch of an outer wall 9 post-pouring strip, a trapezoid cover plate is covered outside the notch of the post-pouring strip, two ends of the cover plate are abutted against outer walls 9 at two sides of the notch, the cover plate is connected with the steel bar 8 through a plurality of connecting pieces, a waterproof layer 11 is covered outside the cover plate and the outer walls 9, and a protective layer 12 is arranged outside the waterproof layer 11.
When the method is implemented, the cover plate is hoisted to one side of the post-pouring strip gap by the crane, and then the cover plate is connected with the outer wall 9 steel bars 8 by using the connecting piece, so that the post-pouring strip gap is blocked.
In addition, the trapezoid cover plate is convenient for sintering the waterproof coiled material on the cover plate and the outer wall 9, and a gap is avoided at the joint of the cover plate and the outer wall 9.
The cover plate consists of a plurality of trapezoidal steel plates 1, a plurality of guide rail channel steel 2 are welded on the steel plates 1, insertion pipes 13 are fixedly connected in one ends of the guide rail channel steel 2, and one ends of the insertion pipes 13 are exposed out of the steel plates 1. The structure is to segment the cover plate, and the segmented purpose is to enable a worker to manually splice the steel plate 1 into the cover plate, so that a crane is not required to be used, and the post-pouring strip notch which cannot be hung in a narrow space or the crane can be plugged.
The guide rail channel steel 2 is internally provided with connecting pieces, each connecting piece comprises a sliding block 7 assembled in the guide rail channel steel 2, the sliding blocks 7 are connected with double-head screws 6 in a threaded mode, and reinforcing steel hooks 5 and threaded connection nuts are sleeved on the double-head screws 6 in a sleeved mode.
This kind of structure makes the connecting piece can reciprocate along guide rail channel-section steel 2 to can let double-end screw rod 6 avoid reinforcing bar 8 and hang reinforcing bar hook 5 to reinforcing bar 8 on, can let the cover plate can conveniently quick install on the post-cast strip breach.
The two sides of the steel plate 1 are provided with extension sections 3, and rubber sheets 4 are fixedly connected to the extension sections 3 in an adhering manner. The sealing effect between the cover plate and the outer wall 9 is improved.
The waterproof layer 11 is a waterproof coiled material of SBS modified asphalt, and the protective layer 12 is an EPS molding polystyrene board. The waterproof performance of the outer wall 9 and the cover sheet is improved.
