Description

Technical Field

[0001] The utility model relates to the technical field of arch tower positioning and installation, and particularly relates to a supporting stiffening skeleton. Background Technique

[0002] An arch tower is a building form with special structures and functions. The arch tower is mainly a structure mainly under compression. When under the action of static loads, when the pressure curve borne by the arch completely coincides with the arch axis, each section on the arch will only bear axial force and will not bear bending moment, shear force, torque, etc. The design of the arch tower aims to minimize the shear force, bending moment, and torque of the section, so as to give full play to the performance of the material. For an asymmetric arch tower cable-stayed bridge, due to the asymmetry of the structure, it will be subjected to relatively large bending and torsion effects that cannot be avoided or reduced.

[0003] During the process of arch tower positioning and installation, multiple steps are involved. Among them, it is necessary to set up a supporting stiffening skeleton under the bridge arch and tightly connect it to the bridge arch through connectors to form a stable spatial structure. The supporting stiffening skeleton is a reinforced concrete or steel structure member that provides temporary support and positioning for the bridge arch or arch tower during the construction process of the arch bridge or arch tower. By providing stable support and accurate positioning, it ensures the stability and safety of the arch bridge or arch tower during the construction process. The supporting stiffening skeleton generally consists of components such as columns, cross beams, and diagonal braces to form a stable spatial structure. These components are tightly connected together through connectors to form an integral structure, jointly bearing construction loads and external forces. The supporting stiffening skeleton has the advantages of high bearing capacity, good stability, and high construction efficiency.

[0004] However, during the construction process of common supporting stiffening skeletons, it is necessary to install steel structure components such as steel bars on the surface of the supporting stiffening skeleton. Before these steel structure components are fixed, it is necessary for workers to manually fix them to prevent displacement, resulting in low installation efficiency. Especially when installing on the side of the column, it is necessary for workers to lift and position the steel structure components. In view of this, this application proposes a supporting stiffening skeleton. Content of the Utility Model

A fixing bolt 63 is threadedly installed on one side of the support plate 62.

[0024] Move the reinforcing bar positioning assembly 6 to the position where the reinforcing bars need to be installed, place the reinforcing bars between the two limit plates 61 to clamp the reinforcing bars, and then tighten the two fixing bolts 63 so that the two support plates 62 fix the limit plates 61 on the installation surface to prevent the displacement of the reinforcing bars before welding.

[0025] Meanwhile, a long column connecting plate 7 is fixedly installed between the two long support columns 1, a first short column connecting plate 8 is fixedly installed between the two first short support columns 2, and a second short column connecting plate 9 is fixedly installed between the two second short support columns 3.
