Description
Technical field
The present invention relates to a kind of construction techniques more particularly to a kind of installation methods of PC component.
Background technique
Precast concrete (PC component) is the prefabricated basis of realization body structure.Its characteristics are as follows: structural behaviour is good
It is good, structural mechanics can be effectively ensured using batch production production, discreteness is small.Speed of application is fast, good product quality, any surface finish
Degree is high, can reach the decorative effect of clear-water concrete, is uniformly coordinated structure and building.The factorial production energy conservation, is conducive to ring
It protects, reduces the noise of site operation.Fire protecting performance is good.
During the construction building of present high-rise, after the completion of in-situ layer structure, the installation of PC component is carried out, is led to
It crosses and reinforcing bar posting is located on connection reinforcing bar, reinforcing bar posting is one block of steel plate, and it is fixed to be got above according to the position of reinforcing bar
Position hole, location hole is covered on reinforcing bar, is then poured, it is ensured that the position of reinforcing bar is certain.PC component is risen with tower crane hook
It is hung to operating surface, when apart from flooring certain distance, the mounting hole of its bottom is directed at steel by hand steered the prefabricated panel of operator
Muscle, then by the sleeve of the bottom of prefabricated panel on reinforcing bar.
Then the internal diameter of the sleeve of existing PC member bottom section can be greater than spacer bar, therefore, when socket, will lead to
Entire PC component has certain error from standard wall line.
Simultaneously as the process being entirely aligned is to need manually-operated, worker is needed to squat down even to fall and check PC
The sleeve of member bottom section and the alignment case of spacer bar, had not only increased artificial burden in this way, but also will increase the dangerous of production
Property.
Entire PC component drops on mounting surface from tower crane, and whole process needs hand steered the PC component of several workers,
Slowly alignment is moved on mounting surface, and entire process needs the lifting operation of long period, while needing enough artificial progress
Coordinative construction, it is time-consuming and laborious.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of installation methods of PC component, meet whole
