Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a shear wall vertical steel bar positioning device. Background Art

[0002] Shear walls include cast-in-place shear walls and prefabricated shear walls. Cast-in-place shear walls are vertical load-bearing structures formed by tying steel bars and pouring concrete on site. They have the characteristics of good integrity, high strength and excellent seismic resistance. It uses the cast-in-place process to cast the wall and the surrounding beams and columns at one time to form a continuous force system. It is especially suitable for high-rise buildings and industrial buildings and can effectively withstand horizontal shear and bending moments. Prefabricated shear walls are factory-prefabricated concrete components. After being transported to the site, they are assembled and connected at nodes to form an overall structure. The core lies in the connection technology, such as sleeve grouting and grout anchor overlap, to ensure the reliability of force transmission between components. Compared with cast-in-place structures, prefabricated construction is fast, but the node process requirements are strict. The construction of cast-in-place shear walls requires on-site formwork, tying steel bars, and pouring concrete. The process is complicated and the cycle is long, but it can achieve seamless structural connection. Prefabricated shear walls are mainly prefabricated, and only assembly and partial casting are required on site. The vertical joints are usually located at the edge of the structure and are connected by cast-in-place strips or grouting; the horizontal joints are connected by overlapping the reserved steel bars or sleeve grouting to achieve integrity. The construction efficiency is high, but the transportation, hoisting accuracy and node grouting quality requirements are extremely high.

[0003] When installing the prefabricated shear wall, it is also necessary to install the upper prefabricated shear wall on the lower cast-in-place structure, and the lower cast-in-place structure has high requirements for the accuracy of vertical steel bar installation, otherwise the sleeve of the upper prefabricated shear wall cannot be installed one-to-one on the exposed steel bars of the lower cast-in-place structure. Although the vertical steel bars of the cast-in-place shear wall are not as accurate as those of the prefabricated shear wall, the compressive bearing capacity of the cast-in-place shear wall installed in different positions is different in design, so the specific design of the vertical steel bar distribution is also different. However, for the cast-in-place shear wall with the same load, the vertical steel bar distribution is the same. However, for specific civil engineering construction, the construction of prefabricated concrete shear walls and the construction of cast-in-place concrete shear walls both exist. Improving the installation accuracy of the vertical steel bars in the lower cast-in-place structure of the prefabricated concrete shear wall will undoubtedly improve the reliability of the installation between the upper prefabricated shear wall and the lower cast-in-place structure. Improving the distribution accuracy of the vertical reinforcement of the cast-in-place concrete shear wall is also conducive to the constructed cast-in-place concrete shear wall to achieve the preset design parameters.

[0004] For prefabricated concrete shear walls, the vertical steel bars can be positioned using vertical steel bar positioning molds according to the design parameters during the installation process. However, if the design parameters are inconsistent and the vertical steel bar distribution is not the same, a single positioning mold cannot be used. For cast-in-place shear walls, although the installation accuracy of vertical steel bars is not as high as that of prefabricated concrete shear walls, if positioning molds can be used to position the vertical steel bars during the installation stage of cast-in-place concrete shear walls, the installation accuracy of vertical steel bars in a single cast-in-place concrete shear wall can be improved, and the repetitive work of repeated measurements during the vertical steel bar positioning process of multiple cast-in-place concrete shear walls of the same specifications can be reduced. Therefore, there is a technical demand for designing a vertical steel bar positioning mold that can be applied to the construction of cast-in-place concrete shear walls with different vertical steel bar distributions and the construction of the lower cast-in-place structure of prefabricated concrete shear walls. Therefore, there is room for improvement in the existing technology to meet the needs of the market. Utility Model Content
