Description
Technical field
The present invention relates to a kind of construction techniques, more particularly to a kind of installation method of PC components.
Background technology
Precast concrete (PC components) is the prefabricated basis of realization body structure.Its feature is as follows：Structural behaviour is good
Good, structural mechanics can be effectively ensured by being made using batch production, and 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, structure is uniformly coordinated with building.Factorial praluction is saved, and is conducive to ring
Protect, reduce the noise of site operation.Fire protecting performance is good.
During the construction building of present high-rise, after the completion of cast-in-place Rotating fields, the installation of PC components is carried out, is led to
Cross and reinforcing bar posting is positioned on connection reinforcing bar, reinforcing bar posting is one block of steel plate, it is fixed to be got above according to the position of reinforcing bar
Position hole, positioning hole is enclosed on reinforcing bar, then poured, it is ensured that the position of reinforcing bar is certain.PC components are risen with tower crane hook
Operating surface is hung to, during apart from flooring certain distance, the mounting hole of its bottom is directed at steel by operating personnel with hand steered prefabricated panel
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 sections can be more than spacer bar, therefore, when socket, can cause
Whole PC components have certain error from standard wall line.
Simultaneously as the process being entirely aligned is that needs are manually-operated, it is necessary to which workman, which squats down even to fall, checks PC
The sleeve of member bottom section and the alignment case of spacer bar, had so both added artificial burden, can increase the dangerous of production again
Property.
Whole PC components are dropped on mounting surface from tower crane, and whole process needs several workmans with hand steered PC components,
Slowly alignment is moved on mounting surface, and whole process needs the lifting operation of long period, while needing enough artificial progress
Coordinative construction, wastes time and energy.
