Description

Technical Field

[0001] The invention relates to building construction, in particular to a method for measuring the verticality of a template with a suspended fixing frame. Background Art

[0002] The converter equipment foundation is an important concrete foundation for steelmaking. The steelmaking converter equipment foundation is generally about 7-8m high, about 9m long, and about 5m wide. Before installation, the bottom positioning line is used to splice and install the template. After installation, the theodolite is used for re-measurement. The width of the equipment foundation is relatively large, and the tightening of the tension bolts will affect the template offset. Since the concrete foundation is long and high, there will be deviations when directly measuring the verticality of the template using a plumb line and theodolite (which is greatly affected by the external environment). According to previous construction experience, the deviation reaches 20-30mm. After the template is removed, the concrete wall will be uneven and offset. Summary of the invention

[0003] The present invention aims to solve the above technical problems, thereby providing a method for measuring the verticality of a template by a suspended fixing frame, thereby improving construction accuracy and construction quality.

[0004] The present invention solves the technical problem and adopts the following technical solution: A method for measuring the verticality of a template using a hanging fixed frame comprises the following steps: S1. Make a fixing frame, which is a groove type; S2. Formwork support The main keel steel pipe and secondary keel wood are supported outside the formwork; S3, Fixing bracket installation The open end of the fixing frame faces the template, and the upper horizontal part of the fixing frame is placed on the main keel steel pipe; S4. Installation of plumb line Install the plumb line on the outer side of the vertical part of the fixing frame; S5. Use a ruler to measure the distance from the template to the plumb line to determine whether the verticality of the template is deviated.

[0005] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: The production and operation are relatively simple, convenient and safe, which reduces labor costs. It can measure the verticality of the template more quickly and accurately than the theodolite, ensuring accuracy while performing construction efficiently to improve construction quality.

[0006] Further, the optimization scheme of the present invention is: An arc-shaped positioning groove is provided on the bottom surface of the upper horizontal portion of the fixing frame.

[0007] The length of the horizontal portion of the fixing frame is smaller than the length of the vertical portion.

[0008] The main keel steel pipe is arranged horizontally, and the secondary keel wood is arranged vertically.

[0009] The upper end of the hanging line of the plumb line is fixed to the corner of the vertical part and the upper horizontal part of the fixing frame.

[0010] The inner ends of the upper horizontal part and the lower horizontal part of the fixing frame are in close contact with the outer plate surface of the template. BRIEF DESCRIPTION OF THE DRAWINGS
