Floor slab hole plugging device and method

Abstract

The invention discloses a floor slab hole plugging device and method. The floor slab hole plugging device comprises a supporting plate, a pulling rod and a fixing plate. The supporting plate and the fixing plate are horizontally and parallelly arranged and distributed on the pulling rod in sequence from bottom to top. The pulling rod is sleeved with a sleeve. The length size of the sleeve is larger than the thickness size of a floor slab. The sleeve is arranged between the supporting plate and the fixing plate. The supporting plate and the pulling rod are connected and fixed through welding. The fixing plate is connected with the pulling rod through a thread and can be moved and adjusted up and down along the pulling rod through the thread. A plurality of cushion blocks are further arranged on the lower end surface of the fixing plate and are uniformly distributed along the center of the fixing plate. During working, the supporting plate covers the lower portion of a floor slab hole, is closely attached to the lower end surface of the floor slab and is used for plugging a lower end opening of the floor slab hole; the pulling rod penetrates through the floor slab hole and is connected with the fixing plate covering the upper portion of the floor slab hole; and the cushion blocks are distributed between the fixing plate and the floor slab. Operation is easy; the construction efficiency and the construction safety are improved; turnover repeated use can be achieved; the construction quality is improved; and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a floor hole sealing device and method. Background technique [0002] During the construction of the concrete floor slab, some circular or square holes of different sizes are reserved to meet the construction needs such as measurement and hanging objects or the requirements of the design drawings. After the construction of the project is completed, these holes need to be backfilled with concrete. At present, there are generally the following methods for floor hole sealing: [0003] Method 1. The supporting board is made of wood plywood, and the galvanized iron wire is drilled on the supporting board. The lower end of the galvanized iron wire is bound to the clamp (the clamp usually adopts a steel bar head) to fix the pallet, and the upper end of the galvanized iron wire is connected to the fixing rod (the fixing rod is usually The steel bars placed on the concrete...

AI Technical Summary

Problems solved by technology

[0005] The problems of the above methods are: ①. Manually use a ladder to remove the supporting plate, which has great potential safety hazards and low construction efficiency; ②. The galvanized steel wire is embedded in the concrete, which affects the quality of the concrete and wastes materials; ③. The wood plywood is easy to deform , Opening holes in the wood plywood will easily lead to grout leakage and affect the appearance quality of the concrete; ④Use a crowbar to violently remove the supporting board, which will easily lead to damage to the supporting board and unfavorable turnover; ⑤It is difficult and easy to remove the cement nails nailed into the original concrete Destroy the concrete surface of the original floor slab ceiling
