Description
Technical Field
The invention relates to a high-efficiency installation method and a device thereof for a precast concrete wallboard, in particular to a precast concrete wallboard structure, a positioning and inspection link of the production process of a grouting sleeve and a reserved vertical steel bar, position degree inspection of an assembly site, a correction method for unqualified verticality of the reserved vertical steel bar, correction of unqualified grouting sleeve position degree and verticality and unqualified reserved steel bar position degree, inspection of verticality after a composite floor slab bottom supporting structure and a wallboard are installed and the like.
Background
The pre-buried position of reinforcing bar and grout sleeve is decided by the casting die frame at precast concrete wallboard in process of production, because the clearance volume of frame locating sleeve and reinforcing bar locating hole is big, the side forms is thinner, location direction length is short etc. reason, the position degree and the straightness that hangs down of sleeve and reinforcing bar often can not effectively guarantee in process of production. In an assembly construction site, a special inspection tool for the position degrees of a sleeve and a reserved steel bar, a reserved steel bar adjusting tool and a repairing method and device for an unqualified wallboard are lacked at present, a tower crane is often required to hang the wallboard to wait for the correction of the reserved steel bar when the sleeve or the reserved steel bar is unqualified and is not matched, even a wallboard component cannot be installed due to the lack of a feasible and reliable repairing method, and the construction safety, quality and efficiency are seriously influenced. Moreover, when the position degree of the reserved steel bars of the wallboard at the bottom layer is unqualified and the prefabricated building can not be repaired, the assembled whole floor slab, beam and other structures are required to be dismantled sometimes, so that the time is wasted, the construction cost is increased, and the high efficiency of the high-efficiency construction of the prefabricated building can not be effectively realized. When supervision is not in place, part constructors can even rule violating the careless rate and cut off the vertical reinforcing bar that does not go into a section of thick bamboo and direct assembly, leads to actual connection reinforcing bar quantity to reduce, and the quality hidden danger is serious.
Secondly, because floor and upper wallboard are heavier, in the upper wallboard installation process, often can produce great concentrated load and act on lower floor's floor, lead to its local overload destruction or whole unstability easily. The existing full-tire-mold all-directional supporting technology has the advantages of low supporting and dismantling efficiency, huge material consumption, increase of dead weight of the whole floor, abnormal narrow and small lower-layer operation space, no targeted support in the maximum stress area, direct action of a supporting structure on a laminated floor slab which does not reach necessary strength after lower-layer pouring, serious surface damage, need of repair and potential safety hazard of the laminated floor slab under pressure.
On the other hand, the existing wallboard verticality inspection generally places an instrument on a floor slab, firstly adjusts the instrument to be horizontal, measures the horizontal level step by step at multiple points, can inspect the wallboard verticality, is low in working efficiency and easy to be interfered by external factors and human factors, or detects in a low-precision mode such as a plumb bob and a running rule, and cannot give consideration to high efficiency and high precision.
Therefore, in order to solve the above-mentioned drawbacks and defects of the prior art, it is necessary to research an efficient installation method of precast concrete wall panels and an apparatus thereof.
