Embodiment 1

[0020] like figure 1 As shown, in this embodiment, a support device for installing a tunnel arch includes a support tube 4, an adjusting nut 3 rotatably arranged at one end of the support tube 4, an adjusting screw connected to the adjusting nut 3 and slidingly arranged in the support tube 4 2. A card slot 1 arranged at the free end of the adjusting screw 2 and perpendicular to the adjusting screw 2 .

[0021] During construction, install the supporting device in place, set the card slot 1 upwards, install the steel arch in the card slot 1, and turn the adjusting nut 3 to drive the adjusting screw 2 up and down, raise the steel arch to the design height, and then Fixed steel arches. When needed, the steel arch can be pressed against other structures by raising the adjusting screw 2, and the steel arch can be kept in place by self-locking of the thread.

Embodiment 2

[0023] On the basis of the above embodiments, in this embodiment, an adjustment handle 31 is connected to the adjustment nut 3 . By setting the adjusting handle 31, it is convenient to turn the adjusting nut 3 through the adjusting handle 31, so that the operation is more convenient and fast.

Embodiment 3

[0025] like figure 2 As shown, on the basis of the above-mentioned embodiments, in this embodiment, a brace 6 is provided between the clamping groove 1 and the adjusting screw 2 . The use of the brace 6 can support the slot 1, which is beneficial to improve the stability and rigidity of the slot 1, and prevent the slot 1 from tilting under the action of external force to affect the positional accuracy of the steel arch.

[0026] In this embodiment, there are two diagonal braces 6 and they are symmetrically distributed on both sides of the adjusting screw 2 . Two diagonal braces 6 are symmetrically distributed on both sides of the adjusting screw 2 , which is beneficial to balance the force on the slot 1 and enhance the supporting effect of the diagonal braces 6 on the slot 1 .

Abstract

The invention discloses a tunnel arch frame mounting and supporting device and a using method thereof. The tunnel arch frame mounting and supporting device comprises a supporting pipe, an adjusting nut rotatably arranged at one end of the supporting pipe, an adjusting screw connected with the adjusting nut and slidably arranged in the supporting pipe, and a clamping groove formed in the free end of the adjusting screw and perpendicular to the adjusting screw. The tunnel arch frame mounting and supporting device has the beneficial effects that a steel arch frame is supported by adopting the clamping groove, the steel arch frame can be limited by utilizing a groove-shaped structure, the rotating freedom degree of the steel arch frame is limited, and the positioning precision of a steel component is improved advantageously; and the clamping groove has a certain length, the contact area of the clamping groove and the steel component can be increased, thus the stability of the steel component is improved, and the height of the steel component can be adjusted conveniently through the adjusting screw.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a support device for installing a tunnel arch frame and a method for using the same. Background technique [0002] Tunnel construction is an underground excavation project, which is carried out in a relatively small and limited space. In the tunnel, when the steel arch is installed manually or supported by wooden squares, its position cannot be well controlled, and more labor is required, the installation is not easy to control, the safety risk is large, and the spacing of the arch is not easy to control, and there are deviations Larger, resulting in poor construction accuracy. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a tunnel arch installation support device and its use method, which are used to improve the construction accuracy of the steel arch and reduce the dif...
