Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building template installation, and relates to a structure for preventing a tall template from misaligning. Background Art
[0002] Today, my country's construction industry is developing rapidly. In the main structures of high-rise buildings and large venues, shear walls and columns are like the backbone of the structure, especially the ultra-high shear wall and column structures. Its quality problems cannot be ignored. If the joints are not handled properly, there will be quality problems such as root rot, misalignment, and shear wall structure opening formwork offset and deformation. In the construction of high-rise buildings and large venues, the basement shear walls, main exterior walls, fire stairs and elevators and other reinforced concrete shear walls, columns, formwork joints or construction joints often have quality problems such as misalignment, leakage, honeycomb surface, etc. after the formwork is removed. The visual quality is poor, which greatly increases the workload of the base treatment before the next construction process, affects the construction quality of the plaster layer, and also causes an increase in construction costs.
[0003] A tall formwork support system refers to a formwork support system with a concrete component formwork support height of 8m and above, a span of 18m and above, a total construction load of 15kN / ㎡ and above, and a concentrated line load of 20kN / m and above at the construction site of a construction project.
[0004] At present, the joints of formwork in the construction field are mainly treated by formwork docking or sponge strips. The formwork has a great impact on the workers, and the probability of joint misalignment and leakage is high; sponge strips can effectively suppress the leakage of formwork joints, but have little effect on misalignment, especially in tall concrete structures, where layered misalignment occurs and the accumulated error leads to a large deviation in the verticality of the tall concrete structure. The use of a device to prevent the misalignment of tall formwork can effectively solve the problems of misalignment of tall formwork joints, leakage, and verticality deviation of tall concrete structures.
