Embodiment 1

[0032] Embodiment 1 of the present invention provides an integrated construction method for cable traction and tensioning of a cable-supported grid structure, such as Figure 1-Figure 3 shown. in, figure 1 A three-dimensional perspective view of a stadium to which the invention is applicable is shown. The cable grid structure includes a support frame 21 arranged in a ring, a roof grid structure 22 arranged on the upper part of the support frame 21 , and a cable structure arranged below the roof grid structure 22 . Preferably, the support frame 21 is a steel structure support frame. Among them, the cable structure includes hoop cables 23 and radial cables 24 connected with the hoop cables 23. After the support frame 21 and the roof grid structure 22 are installed, all the cable structures are assembled on the ground. , and then carry out traction tension forming construction on all the assembled cable structures, wherein, the construction method also includes the following s...

Embodiment 2

[0041] Embodiment 2 of the present invention provides an integrated equipment for cable traction and tension with a cable-supported grid structure, such as Figure 4 as shown, figure 1 It shows a structural schematic diagram of the integrated equipment for cable traction and tension of the cable-supported grid structure of the present invention. The integrated equipment of the present invention at least includes a tooling cable 19, a traction fixture 11 for fixing the tooling cable 19, and a lifting and pulling device 15 arranged at one end of the tooling cable 19 away from the traction fixture 11, wherein the traction fixture 11 can Be fixed to vertical traction fixed force point 27 and oblique traction fixed force point 28.

[0042] Wherein, the towed rope 12 is arranged between at least two tooling ropes 19, and is connected with the hoisting traction device 15, and the hoisting traction device 15 is connected with the hydraulic pump station 17 to provide power, and the hy...

Abstract

The invention provides a cable-supported grid structure cable system traction and tension integrated construction method and equipment, relates to the technical field of construction engineering, and solves the problem of tensioning and tensioning of the cable system used in the cable-supported grid structure in the prior art. Time-consuming and labor-intensive technical problems with poor results during traction construction. The construction method of the present invention divides all traction points into vertical traction points and oblique traction points that are distributed at intervals, and the construction is carried out in a manner of matching vertical traction and radial traction, on the one hand, the steel structure support frame is reduced. Safety risks, greatly reducing the traction value of each traction point, and can also artificially avoid the support frame that is too close to the radial cable; on the other hand, it makes the cable network configuration more intuitive; doubles the traction efficiency and shortens the construction period. controllable.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an integrated construction method and equipment for a cable-supported grid structure with cable traction and tension. Background technique [0002] At present, in the construction process of stadiums, some steel structures of gymnasiums use large-opening spoke-type cable-supported grid structures. Cable-supported grid structures are a new type of hybrid prestressed spatial structure system. This structure is improved on the basis of single-layer reticulated shells, which not only retains the advantages of single-layer reticulated shells in terms of performance and structural form, but also absorbs the purification of the overall structure of tension. The entire structure consists of a single-layer spherical reticulated shell, struts and prestressed cable systems. Due to the large span of the gymnasium, the roof of the gymnasium needs to be supported by a steel s...
