The invention discloses a tool type temporary plugging device for a construction reserved hole. The cross section of the reserved hole is round. The tool type temporary plugging device comprises a bolt (3), a fixing pin (2), a nut (6), a waterproof pressing plate (5), a waterproof rubber gasket (7) and waterproof rubber rings (8). An annular ring (1) is arranged at one end of the bolt (3), external threads (4) are arranged at the other end of the bolt, the fixing pin (2) is matched with the annular ring (1), the end, provided with the external threads (4), of the bolt (3) sequentially penetrates through the reserved hole, the waterproof rubber rings (8), the waterproof pressing plate (5) and the waterproof rubber gasket (7) so as to be connected with the nut (6). The bolt is used for tightening the waterproof pressing plate, the waterproof pressing plate, the waterproof rubber rings and a wall or a board are made to be tightly combined, the reserved hole can be conveniently and temporarily plugged, waterproofness of the reserved hole in the wall or the board in the construction process is achieved, and water for construction or rainwater or underground water is prevented from entering a floor on the lower portion in the construction process.
Description
Technical field [0001] The invention relates to the field of building construction, in particular to a tool-type device for temporarily blocking a reserved hole for building construction. Background technique [0002] In the construction of our country, it is generally used to reserve openings in the cast-in-situ reinforced concrete structure to install various wall (slab) pipes. But generally due to the long construction period and complex environment, and the installation of formal pipelines requires certain procedures and cycles. During this period, a large amount of construction water, rainwater or groundwater will sink to the lower floors through the reserved openings on the wall (board), especially It is the basement. Due to excessive water inflow, it poses a certain threat to the construction period, personnel safety and property. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a tool-type ...
