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

A construction method suitable for a polygonal wind tunnel structure and its application, comprising the construction steps of frame columns, the construction steps of lower frame beams, the segmental construction steps of tunnel body plates, the construction steps of upper frame beams and the steps of removing a support system. During the construction process, the frame columns and frame beams form a quadrilateral, a plurality of hole panels are located in the quadrilateral surrounded by the frame columns and the frame beams, and form a polygon, and a plurality of support rods form a support In the frame, the two ends of the support rods are fixed with connection nodes, and the connection nodes support the hole body plate through pads. During the construction of this method, the hole body slab can be constructed from bottom to top, and after a construction stage is completed, the support system can be removed, so as to be recycled for the next support system. The construction method can effectively improve the construction precision and reduce the inner space of the cave body occupied by the construction.

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. ...
