Description

Construction auxiliary system and construction method of modularized building Technical Field The invention belongs to the technical field of modularized building construction, and particularly relates to a construction auxiliary system and a construction method of a modularized building. Background The steel-concrete combined modular building is an important development direction of building industrialization, and the main body structure, pipeline pre-embedding and internal decoration of building units are completed in factories, and the building units are transported to the site for hoisting and assembling, so that the construction period can be obviously shortened, and the building quality can be improved. The whole-flow construction of the modularized building mainly comprises the conventional construction method of procedures such as transportation fixing, hoisting in place, reinforcing steel bar connection among modules, mounting of a rear sealing plate and the like. The main flow and the existing disadvantages of the prior art are as follows: 1. problem of deformation of modules during transportation In the transportation of steel-concrete combined modular building units, the modules are usually fixed on the transport vehicle only by simple fixing methods (such as placing a skid under the modules, and binding the modules on the transport vehicle by ropes on two sides). Jolt and vibration can be generated in the running process of the vehicle, so that the module is deformed such as bending and twisting. The deformation not only can influence the structural dimensional accuracy of the module and reduce the product quality, but also can cause that the module can not be successfully butted to a preset position during on-site hoisting, thereby increasing the adjustment difficulty and even influencing the assembly quality of the whole structure. 2. Precision and efficiency problems of hoisting in place The existing module hoisting process mainly relies on manual pushing and pulling, visual inspection and other modes of constructors to guide the module to move so as to align the module with a positioning line or a datum point. The method is greatly influenced by human factors, construction precision is difficult to guarantee, efficiency is low in hoisting of large or heavy modules, construction period is prolonged, and labor cost is increased. 3. Inter-module rebar joining operation difficulty and potential safety hazard After the modules are lifted, connecting steel bars are required to be arranged between adjacent modules and welded. Because the joints between the modules are narrow, the constructors need to insert the reinforcing bars into the gaps by bare hands and continuously support the reinforcing bars in the welding process. The operation is not only laborious, but also easy to cause safety accidents such as hand scalding and scratching due to the fact that the steel bars slide or are high Wen Hanzha, and meanwhile, the welding quality is greatly influenced by the stability of people. 4. Processing quality problem of the rear sealing plate After the welding of the connecting reinforcing steel bars between the adjacent modules is completed, a rear sealing plate is required to be installed between the modules, and the rear sealing plate is usually made of cement fiber boards and is required to be cut on site according to the size. Traditional cutting tools (such as a common cutting machine) are difficult to ensure the straightness and flatness of the cut, and the installation quality and appearance effect of the sealing plate are affected. 5. Mounting efficiency problem of rear sealing plate When the sealing plate is installed, a guiding hole is formed in the steel column, and then a hole is drilled in the cement fiber board to be fixed by matching with a self-tapping screw. Because cement fiberboard shelters from the hole location of leading, the location must be extremely accurate, otherwise the screw is difficult to aim at the hole of leading, leads to installation difficulty, inefficiency, and the workman need consume great physical power and accomplish fastening operation. In summary, the existing modularized building construction method has obvious defects in the links of transportation protection, hoisting and positioning, steel bar connection, rear sealing plate installation and the like, and is mainly characterized in that the modules are easy to deform to influence quality and installation, the hoisting precision is low, the efficiency is low, the steel bar connection operation is dangerous and inconvenient, the processing quality of the rear sealing plate is unstable, and the installation is complicated. These problems restrict the quality improvement and efficiency optimization of the steel-concrete combined modular building construction, and therefore, it is necessary to provide a construction auxiliary system and a construction method to solve the problems.
