Blocking device suitable for small-area floorslab cave hole

Abstract

The invention discloses a blocking device suitable for a small-area floorslab cave hole. The device comprises an upper sealing plate, a lower sealing plate and a connectingfastening assembly connecting the upper sealing plate and the lower sealing plate; the upper sealing plate comprises a sinking type round upper sealing body in the middle and a ladder-shape upper hole sealing edge extending upward and outward along the edge of the top portion of the upper sealing body; the lower sealing plate is matched with the shape of the floorslab cave hole and comprises a lower sealing body and a lowerhole sealing side extending outward from the lower sealing body, and multi-level annular pressing grooves protruding upward are formed in the lower sealing body from inside to outside; theconnectingfastening assembly comprises a threaded rod, an upper nut and a lower nut. The device relates to blocking work offloorslab cave holes with the side length less than 200 mm or the diameter less than 200mm on the construction site, all kinds of horizontal cave holes of floorslab wire releasing cave holes, waste water supplying pipeline cave holes, rod piece dismantling waste cave holes and the like can be blocked, the device has the advantages that free combination is achieved, installing is quick, and the operation is simple and convenient, and it is avoided that after repairing by blocking conventional horizontal cave holes, the common quality problem of leakage is easily caused.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a building floor construction device, in particular to a plugging device suitable for small-area floor openings. Background technique [0002] At present, in the building construction site, during the whole process of building construction, it is often necessary to open horizontal openings on structural components due to reasons such as changes in construction technology and drawing design. For example, openings are opened in the concrete floor for elevation positioning detection; the original design pipeline is changed, which makes the reserved openings invalid; the openings left after the wall-through-slab rods are removed, etc. In the later stage, horizontal hole sealing treatment is required. [0003] The traditional sealing treatment of floor openings usually seals the horizontal openings by chiseling, planting bars, hanging formwork to pour concrete slurry, and vibrating...

AI Technical Summary

Problems solved by technology

[0003] The traditional sealing treatment of floor openings usually seals the horizontal openings by chiseling, planting bars, hanging formwork to pour concrete slurry, and vibrating for maintenance. The construction experience and proficiency requirements are relatively high. If the concrete construction is not compacted by vibration or maintenance is not in place, cracks will easily occur, which will easily cause hidden dangers of leakage.
