Embodiment 1

[0046] Such as Figures 1 to 9C As shown, the present invention provides a cable dome structure with limited installation space, its construction form is a combination of Levy type and Geiger type, the inner side is a Geiger type cable system part 2, and the outermost ring is a Levy type cable system part 1 . The cable dome structure includes a central tension ring 3, ridge cables, oblique cables, hoop cables, struts 14 and outer pressure ring boundary members 9, the ridge cables include a plurality of outer ridge cables 10 and inner ridge cables 12, and the oblique cables include a plurality of outer ridge cables. The oblique cables 11, the inner oblique cables 13 and the upper oblique cables 8, the hoop cables include the outer hoop hoops 5, the middle hoop hoops 6 and the inner hoop hoops 7, the hoop hoops are pulled by single or multiple steel The cables are side by side to bear the hoop cable force. Among them, the inner side of the Levy-type cable system part 1 is conn...

Embodiment 2

[0050] In a preferred embodiment, the outer ring pressure ring boundary member 9 is connected with the outer ring pressure ring boundary embedment, and the outer ring pressure ring boundary embedment has two forms, including the outer ring pressure ring boundary embedment one 91 and the outer ring pressure ring boundary embedment Pressure Ring Boundary Embed II 92. Among them, such as Figure 3A As shown, two ear plates 912 are provided on the bottom plate 911 of the outer ring pressure ring boundary embedded part 1 91, and each ear plate 912 is provided with an outer ridge cable connection part 913 and an outer oblique cable connection part 914, respectively for The outer notochord 10 and the outer oblique cord 11 are connected. A plurality of ring beam construction plates 915 are vertically arranged on the bottom plate 911 . Such as Figure 3B As shown, an ear plate 922 is provided on the bottom plate 921 of the outer ring pressure ring boundary embedment part 2 92 . The...

Embodiment 3

[0056] The present invention also provides a method for forming a cable dome structure with limited installation space as described above, comprising the following steps:

[0057] Step S1. According to the stress characteristics of the cable dome structure, by analyzing and comparing the advantages, disadvantages and feasibility of various methods of applying steel cable prestressing, it is determined to use the tire frame to assemble the central tension ring, and install the notches and obliques in blocks and partitions. The way of cable and hoop cable components, and choose to build the prestress in the way of tensioning the outer cable at one time.

[0058] Step S2. Establish the overall structure calculation model of the cable dome structure, and carry out the simulation analysis of each construction stage, to give the configuration and stress of the cable dome structure at each construction stage and determine the cable length of the steel cable, for key construction stage...

Abstract

The invention discloses a cable dome structure with a limited installation space and a forming method thereof. The cable dome structure is characterized in that the inner side of a cable dome is a Geiger type cable system part, the outermost ring is a Levy type cable system part, the cable dome structure with the limited installation space comprises a central tension ring, a ridge cable, an inclined cable, an annular cable, a supporting rod and an outer ring pressure ring boundary component, the ridge cable, the inclined cable and the annular cable are separately composed of a plurality of circles, and each circle of annular cable is composed of one or more steel inhaul cables side by side; and the inner side of the Levy type cable system part is connected with the Geiger type cable systempart through an inner and outer ridge cable connecting node and an outer ring circumferential cable clamp node, and the outer side of the Levy type cable system part is directly connected with the outer ring pressure ring boundary component through an outer ridge cable and an outer inclined cable. The method is suitable for the construction site of a full-flexible cable dome structure system withthe limited installation space.

Description

technical field [0001] The invention relates to the field of cable dome structures in long-span space structures, in particular to a cable dome structure with limited installation space and a forming method thereof. Background technique [0002] The cable dome structure is one of the long-span prestressed steel structure systems. It is a full-tension system (Tensegrity System) with extremely high structural efficiency. The cable dome structure is a new type of prestressed space structure system mainly composed of cables, rods and roof covering materials (usually membrane materials). In the system, except for a few rods under compression, the rest of the rods are in tension state, which is a full tension system with reasonable force and high structural efficiency. Due to its ingenious structural concept, light appearance, light weight, fast construction, material saving and environmental protection, it has strong vitality and broad application prospects, representing the hig...
