A joint hinge device suitable for automatic construction of constrained concrete arch frames

Abstract

The invention discloses an automatic construction node hinge device suitable for a confined concrete lagging jack. The automatic construction node hinge device comprises a hinge buckle and a hinge groove which are movably connected by virtue of a hinge shaft, wherein the hinge groove is internally hollow, so that the lower end of the hinge buckle is wrapped in the hinge groove; and the lower end of the hinge buckle is provided with a first retainer ring clamping groove, a second retainer ring clamping groove is formed in the corresponding position of the hinge groove, and the hinge buckle and the hinge groove are fixedly buckled. The automatic construction node hinge device is simple in structure and convenient and flexible to install; and the application range is wide, and the node hinge device can be used for different lagging jacks in various shapes, sizes and sectional forms such as a mine U-shaped steel lagging jack, an H-shaped steel lagging jack, and for the confined concrete lagging jacks in various sectional forms and sizes. The node hinge device can be used for connecting nodes of an underground engineering lagging jack and is particularly suitable for connecting confined concrete lagging jacks.

Description

technical field [0001] The invention relates to a node hinge device suitable for restraining automatic construction of concrete arch frames. Background technique [0002] With the rapid development of the scale and speed of tunnel construction, the tunnel will pass through complex conditions such as high stress and weak fracture zones during the construction process. Conventional support methods cannot effectively control the surrounding rock of the tunnel, which affects the safety of the tunnel. Confined concrete support is a relatively strong type of tunnel support, and it is suitable for tunnels with weak surrounding rock geology, well-developed rock joints, high surrounding rock stress, and broken faults. Confined concrete will be divided into several sections during the on-site implementation process, and the tunnel face will be spliced ​​to control the surrounding rock of the tunnel. Therefore, the connection method between the various sections of the confined concrete...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing node connection methods are flange connection and casing connection. During the installation of the arch frame, a lot of work is required for installation, and the labor intensity is high

[0005] 2. The existing node connection method cannot carry out automated construction

[0006] 3. The existing node connection method has slow construction speed, long construction period, and high construction cost. At present, is there any joint hinge device for automatic construction of restrained concrete?
