Construction method and application of load reducing component on underground garage hollow floor

Abstract

The invention belongs to the technical field of construction of load reducing components on underground garage hollow floors, and discloses a construction method and application of a load reducing component on an underground garage hollow floor. The construction method is characterized in that a box body space and anti-floating point positions are determined through scribing on a formwork; bottombars are bound, cushion blocks are placed and pipelines are pre-buried; spacers are bound and limited; the anti-floating points are arranged by using iron wires; a box body is placed, plate surface reinforcing steel bars are bound and drag hooks are arranged; inspection and approval of concealed work are carried out; a construction access road is arranged in an built mode, a concrete conveying pipe is arranged in an erected mode, and concrete is poured; maintenance and mold stripping are carried out. According to the construction method and application of the load reducing component on the underground garage hollow floor, in the concrete pouring process control, vibration needs to be compact, it is guaranteed that vibration leakage and mortal runout do not occur, and the sensory quality ofa concrete component is guaranteed; and finally, protection of the finished product with an optimized design structure is controlled; and a cast-in-place concrete hollow floor formed by the load-reducing component can save a large amount of steel, the concrete, formwork materials and labor, and the hollow floor is light in self weight and high in bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of construction of a load-reducing component on a hollow floor of an underground garage, and in particular relates to a construction method and application of a load-reducing component on a hollow floor of an underground garage. Background technique [0002] There are many types of floor slab systems, mainly including dense ribbed slabs and low ribbed slabs, which create a large space without beams and columns in the structure, so as to achieve the purpose of free and flexible division. This kind of large-bay flexible partition structure system just reflects the requirements of "people-oriented", "residents' participation in design" and sustainable development of residential buildings. [0003] At present, the maximum bay of residential buildings has reached about 6m. However, since the residential structure was still dominated by brick and concrete at that time, and the market for large-bay houses had not y...

AI Technical Summary

Problems solved by technology

However, real-time information or books of hidden projects cannot be accurately monitored

[0011] To sum up, the existing problems in the prior art are: poor structural stability of existing load-reducing member floor application technology; poor seismic performance

The performance of information monitoring during construction is poor, resulting in the ineffective guarantee of construction safety
