Description

Technical Field

[0001] The present invention relates to the technical field of steel bar spacing adjustment, and in particular to a construction auxiliary device and an adjustment method for adjusting the steel bar spacing. Background Art

[0002] In the construction of concrete structures, the arrangement and spacing of steel bars is one of the key factors to ensure the strength and stability of the structure. The arrangement and spacing of steel bars should comply with relevant design specifications and standards. Different types of concrete structures (such as beams, columns, slabs, walls, etc.) have specific steel reinforcement requirements when they are designed. These requirements usually include the diameter, spacing, and cover thickness of the steel bars. Before construction, the construction drawings will mark the position, length, and spacing of each steel bar in detail. The bill of quantities lists the number of steel bars of each specification and length, as well as their distribution in the structure. The steel bars are usually pre-processed into the required length and shape in the factory so that they can be used directly during on-site construction. These prefabricated steel bars can be precisely arranged according to the design requirements, thereby reducing the need for on-site measurement and adjustment. At the construction site, professional measuring tools such as steel bar spacing measuring devices and steel bar displacement meters are usually used to ensure that the spacing and position of each steel bar meet the design requirements. These tools can improve the accuracy and efficiency of construction. During the construction process, the supervision engineers and quality control personnel will regularly check and review the quality of the steel bar arrangement. They will check the position, spacing, connection, and cover of the steel bars to ensure that they meet the building specifications and design requirements.

[0003] Usually, before tying steel cages and steel meshes, lines are drawn first, then the steel bars are placed, and then the steel bars are tied or spot welded. The line drawing method often results in unqualified final steel bar spacing due to the long distance and steel bar slippage. Therefore, a construction auxiliary device that can adjust the steel bar spacing is needed. Summary of the invention
