Technical Field
[0001] The utility model belongs to the field of building construction, and in particular relates to a corrugated pipe grouting kit for prestressed cast-in-place floor slab construction. Background Art
[0002] Prestressed cast-in-place floor slab is a floor slab made at the construction site through a process of supporting formwork, laying prestressed steel bars, pouring concrete, curing and applying prestress.
[0003] During the construction of prestressed cast-in-place floor slabs, a circular hole with a diameter of 20 mm needs to be opened above the corrugated pipe as a grouting hole, which also serves as a drainage hole.
[0004] In order to prepare for the subsequent grouting, the area around the circular hole needs to be processed. The current method is to cover the circular hole with a plastic pressure plate with a mouth and a sponge, and fix it to the corrugated pipe with wire. The surrounding area of the plastic pressure plate is sealed with tape to prevent leakage. A plastic pipe with a diameter of 25mm is connected to the mouth of the plastic pressure plate, extending to 500mm above the board surface to facilitate the subsequent grouting treatment, and also serves as a drainage hole.
[0005] In actual use, due to the poor compatibility of the plastic pressure plate and the corrugated pipe, and the problem of insufficient tightness of the wire binding, leakage is likely to occur during the grouting process.
[0006] Therefore, we propose a corrugated pipe grouting kit for prestressed cast-in-place floor construction to solve the above problems. Utility Model Content
[0007] In view of the problem that in actual use, leakage is likely to occur during the grouting process due to poor compatibility between the plastic pressing plate and the corrugated pipe and the problem that the iron wire is not tightly bound. The utility model provides a corrugated pipe grouting kit for prestressed cast-in-place floor construction.
[0008] The utility model solves the technical problem by adopting a solution: a corrugated pipe grouting kit for prestressed cast-in-place floor construction, comprising at least one self-locking tie and a corrugated pressing plate adapted to the corrugation of the corrugated pipe, wherein the self-locking tie is composed of a belt body and a lock buckle.
[0009] A fixing portion is provided on one side of the corrugated pressing plate, and a through hole corresponding to the grouting hole of the corrugated pipe is opened on the corrugated pressing plate;
[0010] A butt-joint pipe is fixedly connected in the through hole, the lower end of the butt-joint pipe extends to the inner cavity of the corrugated pressing plate, and a detachable grouting pipe is installed at the upper end thereof;
[0011] The lock buckle is fixedly installed on the other side of the corrugated pressing plate, one end of the belt body is connected to the fixing part, and the other end thereof passes around the corrugated hose and passes through the lock buckle to fix the corrugated pressing plate on the corrugated hose.
[0012] Preferably, the lower end of the grouting pipe is a threaded end, and the inner wall of the butt-joint pipe is provided with an internal thread, so that the grouting pipe is threadedly connected to the butt-joint pipe.
[0013] Preferably, the lower end of the butt joint pipe is a tapered end.
[0014] Preferably, a conical rubber ring is provided on the outer side of the conical end.
[0015] Preferably, a sponge is provided between the corrugated pressing plate and the corrugated tube.
[0016] Preferably, a corrugated rubber pad is provided between the corrugated pressing plate and the corrugated tube.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The utility model inserts the butt joint into the grouting hole of the corrugated pipe so that the slurry can be injected into the corrugated pipe through the butt joint during the grouting process. At the same time, the butt joint is in close contact with the grouting hole to prevent the slurry from leaking out. The corrugated pressing plate is buckled on the corrugated pipe and the corrugated pressing plate is fixed on the corrugated hose with a self-locking cable tie. The corrugated pressing plate has good adaptability and close fit with the corrugated pipe, which further prevents the slurry from leaking around the grouting hole during the grouting process, avoids slurry waste, and improves the grouting efficiency.
[0019] 2. The utility model designs the lower end of the butt-joint pipe to be a tapered end, so as to facilitate the rapid insertion of the lower end of the butt-joint pipe into the grouting hole, and provides a tapered rubber ring on the outer side of the tapered end to enhance the sealing effect.
