Turnover type concrete slab surface hole plugging device for constructional engineering

Abstract

The invention discloses a turnover type concrete slab surface hole plugging device for constructional engineering. The turnover type concrete slab surface hole plugging device is used for solving theproblem of how to efficiently and normatively finish concrete hole plugging work due to the fact that the number of reworking is countless due to the quality problem of slab surface reserved hole plugging. The device comprises an aluminum alloy supporting plate, an aluminum alloy movable beam, a screw embedded part, a lower movable turnover part, an upper movable turnover part, an upper plastic sleeve, a lower plastic sleeve, a lower screw cap, an upper screw cap and a 3-shaped buckle. The device is easy and convenient to operate, a formwork supporting system does not need to be erected, holeplugging of reserved holes of concrete slabs with different thicknesses, different sizes and different shapes in a certain range can be realized, the fixation is firm, the aluminum alloy plate is adopted as the formwork surface, the concrete forming effect is good, it is guaranteed that concrete does not leak slurry through cooperation of edge water stop sealing strips, screw water stop pieces areembedded, the leakage risk caused by embedded parts of the device is prevented, and obvious economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of building concrete construction and is applied to concrete slabs; in particular, it relates to a turnable concrete slab hanging hole device for construction engineering. Background technique [0002] In the construction process of the main structure of the construction industry, in order to meet the needs of technology and construction, it is often necessary to reserve holes on the slab surface, such as the set-out opening for the convenience of measuring the set-out line, the opening of the high-rise concrete pumping pipe through the plate, and the application of the aluminum alloy formwork system. Material transfer holes, special frame bodies and pre-buried holes on the board surface of climbing devices, etc. are reserved at the time. The cross-sectional size of this type of hole that requires secondary sealing is relatively fixed, and it is necessary to bind reinforcement and pour concrete at the hole p...
