Compaction groove screw for Halfen channel, support structure and mounting method

Abstract

The invention discloses a compaction groove screw for a Halfen channel, a support structure and a mounting method. The compaction groove screw comprises a groove-type nut and a bolt, wherein a row of rectangular grooves are formed in each of two transverse ends of the nut, a screw rod is tightly meshed with the lowest circle of a meshing thread of the nut, a clamping plate provided with a central hole is arranged outside the upper end of the screw rod in a sleeving manner, and a spring is mounted outside the screw rod and between the bolt head and the central hole of the clamping plate. The compaction groove screw is preassembled into a whole with pretightening force in a manufacture place for transportation. The support structure is an L-shaped porous butt strap which comprises a horizontal butt strap arranged on an open surface of the Halfen channel and a vertical butt strap for support and is provided with a mounting hole, the upper part of the clamping plate of the compaction groove screw after mounting is arranged above the horizontal butt strap in a clamped manner, and the lower part is arranged in the Halfen channel and in inserted connection with teeth of the Halfen channel. During mounting, all that is needed is to perform manual pushing-in, downwards pressing, rotation, popping, tightly screwing and the like on the compaction groove screw to finish mounting, and axial position adjustment can be realized. Efficient, convenient and accurate mourning is realized, and examination, dismounting and replacement are convenient. Components do not move easily, operation is facilitated, the integrity is good, the safety is high, and the compaction groove screw and the support structure can be applied to railway tunnels, bridge supporting and fixing contact nets, communication signals, electrical equipment and the like.

Description

[0001] (1) Technical field: the present invention relates to the support structure and installation technology of the fixed support on the embedded channel. The pre-buried channel is mainly used in railway tunnels and bridges, and the supports mainly support fixed catenary, communication signals and power equipment. It belongs to the category of tunnels (E21D) and the structure of buildings (E04B). (two) background technology: [0002] There are many high-speed railway tunnels and bridges in China, and there is a huge demand for pre-grooved channels. In recent years, the HALFEN channels of HALFEN, Germany, which are used in tunnels and bridges, are poured into concrete in a pre-embedded manner, and are distributed in places with concrete structures such as tunnels and bridges. See figure 1 ,See figure 2 ,See image 3 , the HALFEN channel 6 is generally a C-shaped channel steel, and there are two non-shaped channels 6.1 on both sides of the upper plane opening, see image...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a compression groove nail for a HALFEN channel, a supporting structure and an installation method, and its purpose is to solve the problem of fixing components for supporting and fixing catenary, communication signals, and electric power equipment on the existing railway tunnel and bridge pre-buried HALFEN channel , the installation is very troublesome, not only difficult to operate, but also impossible to adjust
