Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a scaffold for tunnel construction to solve the problem that in the prior art, since the tunnel is located on the inner side of the mountain, a small amount of water will infiltrate when no cement is poured on the inner side of the tunnel, and the It drips down from the top of the tunnel, while the fastener-type steel pipe scaffolding is constructed of multiple steel pipes, and the fasteners are used to connect them. As the construction time increases, the water droplets on the inner side increase, causing the fasteners to rust and get stuck, which in turn causes inconvenient disassembly later.

Embodiment 1

[0030] Example 1: Please refer to Figure 1-Figure 6 , the specific embodiments of the present invention are as follows:

[0031] Its structure includes a bottom plate 1, a longitudinal steel pipe 2, a cross bar 3, a fastener structure 4, a horizontal steel pipe 5, and a platform 6. The outer side of the steel pipes 2 is mechanically connected, the fastener structure 4 is installed on the outer side of the longitudinal steel pipes 2 and engaged with each other, the horizontal steel pipes 5 are horizontally installed between the fastener structures 4 and mechanically connected, and the platform 6 is horizontally arranged The upper end of the horizontal steel pipe 5 is clamped together; the fastener structure 4 includes a connecting seat 41, a fixed structure 42, a screw 43, and a nut 44, and the fixed structures 42 are welded through the connecting seat 41, and the screw 43 is installed On the right side of the fixed structure 42 and connected by a hinge, the nut 44 is install...

Embodiment 2

[0038] Example 2: Please refer to image 3 , Figure 7-Figure 10 , the specific embodiments of the present invention are as follows:

[0039] The fixed structure 42 includes a fixed seat 421, a connecting structure 422, a movable hoop 423, and a clamping plate 424. The connecting structure 422 is embedded and installed inside the fixed seat 421 and connected by a hinge, and the movable hoop 423 is movably connected to the fixed seat 421. The inner side is fixedly connected with the connecting structure 422 , the clamping plate 424 is arranged on the right side of the movable hoop 423 and is an integrated structure, and the screw rod 43 is hingedly connected to the right side of the fixed base 421 and clamped with the clamping plate 424 .

[0040] refer to Figure 7 The connecting structure 422 includes a protective structure 22a, a port 22b, and an inner shaft 22c, the port 22b is arranged inside the protective structure 22a and is an integrated structure, the inner shaft 22...

Abstract

The invention discloses a scaffold for tunnel construction. Its structure includes a bottom plate, a vertical steel pipe, a cross bar, a fastener structure, a horizontal steel pipe and a platform. The structure is installed on the outside of the vertical steel pipe, the horizontal steel pipe is installed horizontally between the fastener structures, and the platform is horizontally arranged on the upper end of the horizontal steel pipe. The fastener structure includes a connecting seat, a fixing structure, a screw rod, and a nut. The screw is installed on the right side of the fixed structure, and the nut is installed on the outer side of the screw and is connected by a thread. The present invention is provided with a fixed structure on the upper end of the connection seat, which reduces the entry of water droplets, thereby preventing the inner side from rusting, and making the later disassembly more flexible. ; A connection structure is set between the fixed seat and the movable hoop, which will make the flowing water drip vertically without contacting the steel pipe, guide the dripping water, prevent rusting due to long-term contact with water, and facilitate the later stage. disassembly.

Description

technical field [0001] The invention belongs to the field of tunnel construction, and in particular relates to a scaffold for tunnel construction. Background technique [0002] With the continuous development of society, the convenience of travel is also constantly updated. In order to shorten the distance between the two places when building roads in mountainous areas, it is necessary to excavate tunnels, and then construct the tunnels. After the excavation of the tunnels is completed , need to carry out construction on the inner side of the tunnel, then need to use scaffolding, carry out auxiliary work, but existing technology has the following deficiencies: [0003] Since the tunnel is located on the inside of the mountain, a small amount of water will infiltrate and drip down from the top of the tunnel when no cement is poured on the inside of the tunnel. The fastener-type steel pipe scaffolding is constructed of multiple steel pipes, and the When the water drops slide ...
