Problems solved by technology

[0003] It can be seen that the construction of the automobile wind tunnel requires high construction precision on the inner wall of the wind tunnel. Therefore, the construction of the internal mold support system is the most critical step. Moreover, since the diffusion section of the wind tunnel is a gradually deformed structure, the size of each section is different. The same, so, in the construction process, the formwork system of traditional wood formwork and steel pipe scaffolding can no longer meet the requirements of on-site construction and quality accuracy

Abstract

The invention belongs to the technical field of wind tunnel construction methods, and in particular relates to a construction method for an inner mold support system for the diffusion section of a super-large wind tunnel; it includes the following steps: step A, performing structural design on the inner steel cylinder template and the steel structure support frame And entrust it for processing; step B, after the inner steel cylinder formwork and steel structure support frame are processed, pass the inspection and transport them to the construction site, the project department organizes material acceptance, and checks the size and level of each formwork block by block according to the QR code data degree, curvature, chord length and other data to ensure that the design requirements are met; step C, carry out on-site positioning and setting out of each section section of the inner steel cylinder formwork; step D, perform positioning and installation of the inner steel cylinder formwork and the steel structure support frame; the present invention It effectively solves the construction problem of the round-to-square diffusion section of the super-large wind tunnel. Using this method, an internal mold support system that meets the construction accuracy requirements can be built to ensure the smooth completion of the construction.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel construction methods, and in particular relates to a construction method for an internal mold support system for a diffusion section of a super-large wind tunnel. Background technique [0002] With the development of the domestic automobile industry, more and more large-scale automobile companies and research institutes have begun to plan and build their own large-scale concrete vehicle wind tunnels. It gradually becomes a square cylindrical structure, generally more than 30 meters in length. As the inner wall of the wind tunnel flow channel, in order to ensure the quality of the flow field in the test section, such as the uniformity of the airflow velocity distribution, the deviation of the average airflow direction from the axis of the wind tunnel, the pressure gradient along the axis of the wind tunnel, the uniformity of the cross-sectional temperature distribution, the Turbulence and nois...
