Problems solved by technology

Therefore, it is particularly important to improve the support system in the wind tunnel construction process in the construction method, so that the accuracy control ability in the wind tunnel construction process is particularly important. In order to increase the stiffness and accuracy of the support system, the existing wind tunnel support system often uses Too many support rods lead to the occupation of most of the space in the cave during the construction process, which is not only not conducive to cross work, but also has a great impact on the construction of the next construction section in the cycle. In addition, the transition of the support system The occupation of the hole space will also affect the development of measurement setting-out and measurement control

Abstract

The invention discloses a construction method suitable for a polygonal wind tunnel body structure and application. The construction method comprises the steps of frame column construction, lower framebeam construction, cave body plate subsection construction, upper frame beam construction and support system removal. In the construction process, frame columns and frame beams define a quadrangle, cave body plates are located in the quadrangle defined by the frame columns and the frame beams and define a polygon, supporting rods form a supporting frame, two ends of each supporting rod are fixedly connected with connecting joints, and the connecting joints support the cave body plates through cushion blocks. According to the method, the cave body plates can be constructed from bottom to top during construction, and a supporting system can be removed for cyclic use as a next support system after one construction stage is completed. According to the construction method, the construction precision can be effectively improved, and the internal space of a cave body occupied by construction is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method and application suitable for polygonal wind tunnel structures. Background technique [0002] Wind tunnel is the most widely used tool in aerodynamic research and experiment. It can artificially generate and control airflow to simulate the flow of gas around aircraft or objects. Its generation and development are closely related to the development of aerospace science. Wind tunnels are widely used to study the basic laws of aerodynamics, to verify and develop relevant theories, and directly serve the development of various aircraft, through wind tunnel experiments to determine the aerodynamic layout of the aircraft and evaluate its aerodynamic performance. The design of modern aircraft relies heavily on wind tunnels. [0003] In the wind tunnel circuit, the section of the tunnel is mostly octagonal, and the length and width of the section can reach 28m. ...
