Problems solved by technology

Because the piercing pin holes are set on the lugs of the tooling, not only the lugs of the tooling are larger, but also it is difficult to apply to the situation where the configuration of the cable and the design position deviate greatly when anchoring in place

Embodiment Construction

[0035] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0036] Taking the spoke-type saddle-shaped single-layer cable-net roof structure of a stadium as an example, the cable-net has 40 radial cables in total. Divided into three batches, the specific implementation steps are as follows:

[0037] The first step: Install columns (4) of different heights on the ground, install external pressure ring beams (5) above the columns, and se...

Abstract

The invention discloses a construction method for integral lifting and batch step-by-step anchoring of a spoke type single-layer cable net. A cable net structure mainly comprises vertical pillars, an outer pressing ring beam, an inner ring cable and radial cables. Obvious height differences exist in the outer end anchoring nodes of all the radial cables. According to the height differences of the anchoring nodes of the outer pressing ring beam, the radial cables are divided into different batches from a structural low point to a structural high point. The number of the batches is determined according to practical conditions. The integral cable net is lifted through a jack, all batches of the radial cables and the outer pressing ring beam are connected and anchored in batches step by step from the low point to the high point in the lifting process, and finally the structure is formed. According to the construction method, the construction support quantity and the upper air operation quantity can be reduced, the requirement quantity of a large-tonnage lifting system is reduced, installation cost is reduced, tool lightening is achieved, the construction period is shortened, and construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of space cable structures, and in particular relates to a construction method for overall lifting of a spoke-type single-layer cable net and gradual anchoring in batches. Background technique [0002] The spoke-type saddle-shaped single-layer cable net structure mainly includes columns, external pressure ring beams, radial cables and hoop cables. In order to enhance the overall spatial rigidity, the surface of the cable net is similar to a saddle shape, and the elevations of the nodes connected by the cable net and the external pressure ring beam are obviously different. In addition, the pretension force in the cable net is also one of the necessary conditions for the formation of structural stiffness. Inside the cable net, the radial cables and hoop cables are connected by cable clips; at the edge of the cable net, the outer ends of the radial cables are connected to the external pressure ring beams.
