Description

Efficient installation method and device for precast concrete wall panels

technical field

The invention relates to an efficient installation method and device of prefabricated concrete wall panels, in particular to prefabricated concrete wall structures, grouting sleeves and reserved vertical steel bars in the production process of positioning, inspection links and location degree inspection at the assembly site, Correction method for unqualified verticality of reserved vertical steel bars, correction of unqualified position of grouting sleeve, unqualified verticality and unqualified position of reserved steel bars, bottom support structure of superimposed floor, inspection of verticality after wall panel installation, etc. .

Background technique

In the production process of precast concrete wall panels, the pre-embedded position of steel bars and grouting sleeves is determined by the frame of the pouring mold. Due to the large gap between frame positioning sleeves and steel positioning holes, thin side molds, and short positioning guide lengths, etc. The position and verticality of sleeves and steel bars are often not guaranteed in the production process. In the assembly construction site, there is currently a lack of special inspection tooling for the position of sleeves and reserved steel bars, reserved steel bar adjustment tooling and repair methods and devices for unqualified wall panels. From time to time, the tower crane is often required to hang the wall panels to wait for the correction of the reserved steel bars, and even the wall panel components cannot be installed due to the lack of feasible and reliable repair methods, which seriously affects the construction safety, quality and efficiency. In addition, when the position of the steel bars reserved for the bottom wall panel is unqualified and cannot be repaired, it is sometimes necessary to dismantle the assembled floor slabs, beams, and other structures, which wastes time and increases construction costs, so that the prefabricated buildings can be constructed efficiently. Efficiency cannot be achieved effectively. When the supervision is not in place, some construction workers will even cut off the vertical steel bars that do not enter the tube and assemble them directly in violation of regulations, resulting in a reduction in the actual number of connected steel bars and serious potential quality problems.

Secondly, because the floor slab and the upper wall panel are heavier, during the installation of the upper wall panel, a large concentrated load is often generated on the lower floor slab, which is easy to cause partial overload damage or overall instability. The existing full tire mold all-round support technology has low support and removal efficiency, huge consumables, increased self-weight of the entire floor, extremely narrow working space on the lower floor, and no targeted support in the maximum stress area, and the support structure directly acts after the lower floor is poured. Laminated floors that have not yet reached the necessary strength have serious surface damage and need to be repaired, and there is a potential safety hazard of crushing the underlying laminated floor.

On the other hand, in the existing wall panel verticality inspection, the instrument is generally placed on the floor, the instrument is first adjusted to the level, and the horizontal measurement is gradually found at multiple points before the wall panel verticality inspection can be carried out. The work efficiency is low and easy to use. Interference from external and human factors, or the use of low-precision methods such as plumb bob and ruler, cannot take into account both high efficiency and high precision.

Therefore, in order to solve many deficiencies and defects of the above-mentioned prior art, it is necessary to study an efficient installation method and device for precast concrete wall panels.

After the tooling inspection, the wall panel and another wall panel can be installed correctly. Unqualified wall panels that result in sleeves or reserved reinforcement can be quickly corrected at the assembly site. The support frame of the bottom support device of the floor slab is attached to the lower wall panel, which increases the stress area of the floor slab and is supported directly below the area with the greatest stress, which can effectively prevent the laminated floor slab from being damaged due to wall panel installation and adjustment operations. The verticality inspection tool after installation of the wallboard solves the problem of the verticality of the wallboard to the ground during the installation process.
