The invention discloses an I-shaped steel arch frame connecting steel plate welding positioning clamping device. The I-shaped steel arch frame connecting steel plate welding positioning clamping device comprises a first connecting rod, a welding clamp support, a positioning pin, a pressing block, a movable limiting block, a handle and a second connecting rod; the welding clamp support and the movable limiting block are connected through a hinge, the two ends of the handle are used for mounting the end parts of one end of the first connecting rod on the two sides of the top of the clamp supportthrough pins; and the end parts of the other end of the first connecting rod are connected with one end of the second connecting rod, and the other end of the second connecting rod is connected withthe movable limiting block. According to the I-shaped steel arch frame connecting steel plate welding positioning clamping device, the hole distance dimension of a connecting plate can be verified inthe process of welding the connecting plate, the construction quality is improved, the relative position of the finished I-steel of each arch frame is the same as that of the connecting plate, the butt joint precision is improved in the butt joint process of each step steel arch frame, the time of the position of adjusting the steel arch frame is reduced while the ring formation quality of the steel arch frame is guaranteed, manpower is saved, and the butt joint efficiency and quality are improved.
Description
technical field [0001] The invention relates to an I-shaped steel arch frame connecting steel plate welding positioning device for tunnel construction, and belongs to the technical field of tunnel excavation and profile steel arch frame welding. Background technique [0002] With the rapid development of national construction projects, tunnel engineering and underground engineering occupy an increasingly important position in national economic construction. Millisecond blasting and smooth blasting technologies are mainly used for tunnel excavation in my country at this stage. After tunnel excavation, initial support is immediately applied in order to control the appropriate release and deformation of surrounding rock stress and increase the safety strength of the structure. [0003] During the tunnel construction process, according to the tunnel construction principle of the New Austrian Method, the quality of the initial support determines the overall stability of the tunne...
