Problems solved by technology

[0002] When excavating a tunnel, the method of digging while supporting is usually used. The support in the prior art adopts an arched frame. This type of arched frame needs to be made according to the excavation situation of the tunnel to determine the camber of the arched frame. Otherwise, there will be a gap between the arch frame and the inner wall of the tunnel, which will easily cause the support to be weak, and the construction of the arch frame on site will also lead to slow construction speed and delay the construction period

Embodiment 1

[0018] Such as Figure 1-Figure 3 As shown, a steel structure support structure provided by the present invention includes an arched plate 1, and the two ends of the arched plate 1 are respectively fixedly connected to the installation plate 14, and the arched plate 1 is conveniently fixed on the ground of the tunnel through the installation plate 14. superior. The arched plate 1 is supported and fixed by two vertical support columns 4, and both sides above the arched plate 1 are fixedly connected to the vertical plate 31, and one side of the vertical plate 31 is hinged to the arc-shaped plate 3. Provided with a relief hole 11, the first jack 6 is hinged through the first hinge seat 61 on one side of the support column 4, and the telescopic end of the first jack 6 passes through the relief hole 11. The telescopic end of the jack 6 is hinged to the arc plate 3 through the second hinge seat 62 .

[0019] A central hole 13 is provided at the center of the upper side of the arch...

Abstract

The invention discloses a steel structure support structure. The steel structure support structure comprises an arch plate; the arch plate is fixedly supported through two vertical support columns; arc plates are rotationally connected to the two sides above the arch plate; avoiding holes are formed in the arch plate; one sides of the support columns are hinged with first jacks; extension ends ofthe first jacks are fixedly hinged with the arc plates; a center hole is formed in the center of the upper side of the arch plate; a bracket is arranged in the center of the lower side of the arch plate, and is provided with a second jack; and a top plate is fixedly connected to an extension end of the second jack. The steel structure support structure has the following advantages: the steel structure support structure is applied to the tunnel construction, mainly supports tunnels during excavation of the tunnels, is high in applicability, can be adjusted for supporting according to the excavated arches in the tunnels along with excavation of the tunnels, and is fixed with the tunnels as a whole through rivets to further improve the supporting stability.

Description

technical field [0001] The invention relates to the technical field of steel structure support, in particular to a steel structure support structure. Background technique [0002] When excavating a tunnel, the method of digging while supporting is usually adopted. The support in the prior art adopts an arched frame. This type of arched frame needs to be made according to the excavation situation of the tunnel to determine the camber of the arched frame. Otherwise, there will be a gap between the arch frame and the inner wall of the tunnel, which will easily cause the support to be weak, and the construction of the arch frame on site will also lead to slow construction speed and delay the construction period. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a steel structure support structure. [0004] In order to achieve the above object, the present invention adopts the following technical ...
