Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting of assembled subway stations, in particular to a tenon precision control bracket for cast-in-place bottom plates of assembled subway stations. Background Art
[0002] The main function of the tenon precision control bracket is to ensure that components (such as tenons and mortises) can be accurately and firmly connected during the assembly process. This bracket can provide high-precision positioning and fixation, thereby ensuring the quality and durability of the final product.
[0003] Prefabricated subway stations with cast-in-place base slabs often have problems with inadequate precision control of cast-in-place tenons and improper control methods. The cast-in-place base slab formwork is often welded to the main reinforcement of the base slab through positioning steel bars, which makes construction difficult. In the later stage, the tenons of the cast-in-place base slab and the tenons of the assembled side walls often fail to fit together, resulting in the removal of the tenons in the later stage, reducing construction efficiency and increasing construction costs, which seriously affects the quality of structural construction. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] The technical problem to be solved by the utility model is that the tenon of the cast-in-place bottom plate cannot fit with the tenon groove of the assembled side wall, resulting in the tenon being chiseled off at a later stage, reducing the construction efficiency and increasing the construction cost, and seriously affecting the construction quality of the structure.
[0006] (II) Technical solution
[0007] In order to solve the above technical problems, the technical solution provided by the utility model is:
[0008] An assembled subway station cast-in-place floor mortise precision control bracket comprises a chassis flange, a support column, a top support plate, and an adjustment bolt;
[0009] The chassis flange is a steel plate, a support column is welded and fixed on the top surface, a top support plate is welded and fixed on the top surface of the support column, a plurality of adjustment holes are reserved on the top support plate, and adjustment bolts are arranged in the adjustment holes.
[0010] As an improvement, the support column is provided with a pair distributed on the left and right and is constructed as an I-beam structure.
[0011] As an improvement, the adjusting holes are provided with 6 symmetrically distributed ones, and the nuts of the adjusting bolts can cooperate with the adjusting holes to adjust the position of the cover template, and the adjusting bolts are M25 bolts.
[0012] As an improvement, the top support plate is the same size as the chassis flange.
[0013] As an improvement, the brackets are evenly distributed at a longitudinal spacing of 2 meters.
[0014] (III) Beneficial effects
[0015] The advantages of the utility model compared with the prior art are:
[0016] Six M25 adjusting bolts are set on the cover template support frame. The position of the cover template is adjusted by adjusting the position and tightness of the nuts on the adjusting bolts to achieve precise control of the tenon position. BRIEF DESCRIPTION OF THE DRAWINGS
