Problems solved by technology

[0003] The purpose of the present invention is to provide an umbrella-shaped support for a steel structure and its installation method. It is necessary to solve the problem that the existing single-pole support form cannot meet the stress of the component for the distance between the peripheral decorative structure and the main structure. It also solves the technical problems that it is difficult to ensure the installation accuracy of ordinary support rod installation technology and the technical problems of safety hazards in high-altitude hoisting and welding

Embodiment 1

[0038] Embodiment one sees figure 1 As shown, an umbrella-shaped support of a steel structure is connected between the decorative structure 2 and the core tube structure in the main structure 3, and is in the form of a space quadrangular pyramid including four ribs 1, and the tops 1.1 of the ribs meet One point forms the tip of the cone and connects it to the decorative structure 2 , the umbrella rib forms the generatrix of the vertebral body, and the tail end 1.2 of the umbrella rib is connected to the main structure 3 . Umbrella ribs are steel pipes, the diameter of which is D245×8mm, and the material is Q345B. The members of the decorative structure in this embodiment are tubular.

[0039] see Figure 2-6 As shown, the installation method of the umbrella-shaped support of this steel structure, the construction steps are as follows:

[0040] Step 1. Before installing the umbrella-shaped support, set up a temporary support platform for the components to be installed on the...

Embodiment 2

[0052] Embodiment two see Figure 7 As shown, an umbrella-shaped support of a steel structure is connected between the decorative structure 2 and the steel column in the main structure 3. It is a space cone and includes two ribs 1, and the tops 1.1 of the ribs meet at one point The apex of the cone is formed and connected to the decorative structure 2 , the umbrella rib forms the generatrix of the vertebral body, and the tail end 1.2 of the umbrella rib is connected to the main structure 3 . Umbrella ribs are steel pipes, the diameter of which is D245×8mm, and the material is Q345B. The components of the decorative structure in this embodiment are tubular, and the tubular components are cut into tube-shaped components in the figure.

[0053] see figure 2 As shown, the installation method of the umbrella-shaped support of this steel structure, the construction steps are as follows:

[0054] Step 1, before installing the umbrella support, set up a temporary support platform ...

Abstract

The invention discloses an umbrella-shaped steel structure support and an installation method thereof. The umbrella-shaped steel structure support is in the shape of a spatial cone and comprises at least two ribs, wherein the top ends of the ribs are intersected at one point to form the tip of the cone and are connected to a decorative structure in a penetration manner, the ribs form the generatrix of the cone, and the tail ends of the ribs are connected to a main structure. The installation method comprises the construction steps of setting up a temporary support platform, calculating top coordinates and tail coordinates of the ribs, marking the top coordinates, drawing reticule crosses at tail ends, flipping cross wires on the main structure, installing the ribs, adjusting the installation positions of the ribs and welding for connecting finally. According to the support disclosed by the invention, a supporting way of fixedly connecting a steel member with the main structure is adopted, and specifically, a structure form of gathering a plurality of support rods at one point and connecting the support rods in a penetration manner is adopted, so that the stress performance of the support rods is improved, the connectable distance between a decorative steel structure and the main structure is increased to 5-20m, and the installation precision of the umbrella-shaped support is guaranteed while safety guarantee is provided for the large-scale peripheral decorative steel structure.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a support connecting a decorative structure and a main structure and an installation method thereof. Background technique [0002] With the increasing development of building technology, the existing peripheral decorative structures mostly use steel structure shapes, which are generally closer to the edge of the main structure, and the supporting rods between the peripheral decorative structure and the main structure are generally in the The support form of a single rod is set at one support point, especially if the decorative structure is far away from the steel structure, this kind of support rod can no longer meet the stress and safety of the component. Moreover, the common installation technology of supporting rods is to weld and fix the components after they are hoisted in place. On the one hand, it is difficult to ensure the installation accuracy. On the other hand, for...
