Abstract
The invention relates to a plate-typed draw ring used for connecting draw rods on a tunnel metal support, consisting of a bar-shaped steel plate which is provided with holes on two ends and is fixedly welded on a tunnel metal support for installing a draw bar. The bar-shaped steel plate is fixedly welded on the inner outline surface or on the outer outline surface of the tunnel metal support profile steel for installing the draw bar, the centre-line between the two end holes on the bar-shaped steel plate is coincided with the centre-line of the support profile steel, and the positions of the two end holes on the bar-shaped steel plate are out of the contact surface of the tunnel metal support profile steel and the bar-shaped steel plate on the welding position. The plate-type draw ring used for connecting draw rods on the tunnel metal support has reliable structure, the contact surface of the plate-type draw ring and the tunnel steel support profile steel and the total length of the welding joint are large. The plate-type draw ring device has high strength and large bearing capacity, and is difficult to be damaged.
Description
Technical field
The present invention relates to a kind of draw ring device that is connected and fixed pull bar between metallic supports in galleries on the metallic supports in galleries that is welded on, especially a kind of board-like draw ring device that is connected and fixed pull bar between metallic supports in galleries on the metallic supports in galleries that is welded on.
Background technology
At present, known be welded on the metallic supports in galleries with metallic supports in galleries between the pull bar draw ring device that is fixedly connected with usefulness mainly be, be symmetrically welded round bar in the shaped steel two sides that metallic supports in galleries is installed the pull bar position and bend to the draw ring that annulus or steel pipe are cut into pipe nipple, so that the cylinder lever connecting rod both ends between metallic supports in galleries penetrate in the draw ring hole on the adjacent metallic supports in galleries, adjacent metallic supports in galleries is connected to integral body.Concrete structure is: draw ring is after bending to annulus or be cut into pipe nipple with steel pipe with round bar, is welded on metallic supports in galleries and installs on the shaped steel two sides at pull bar position and make.Pull bar usually adopts and processes with round steel between metallic supports in galleries.When tunnel adjacent metal support connected, the pull bar both ends penetrated respectively in the draw ring on the adjacent metallic supports in galleries between frame, adjacent metallic supports in galleries is formed whole, the integrated carrying ability of raising metallic supports in galleries.
Be cut into the draw ring that pipe nipple is made for existing being welded on the metallic supports in galleries with the round bar bending or with steel pipe, the intensity of draw ring own is lower; The contact surface of the draw ring of this class formation form and metallic supports in galleries shaped steel is little simultaneously, fusion length short.The metallic supports in galleries draw ring is stressed when larger, is prone to that draw ring is disrumpent feelings, weld cracking between draw ring and metallic supports in galleries, causes the mass action of metallic supports in galleries to reduce.
Summary of the invention
The own intensity of existing draw ring of welding on the metallic supports in galleries is lower in order to overcome, the shortcoming that contact surface is little, the weld seam total length is less, the metallic supports in galleries draw ring is prone to destruction of draw ring and metallic supports in galleries shaped steel, the invention provides a kind of board-like draw ring device that is connected and fixed pull bar between metallic supports in galleries on the metallic supports in galleries that is welded on.This board-like draw ring intensity is high, bearing capacity is large, uses mass action and supporting effect of roadway that board-like draw ring can improve metallic supports in galleries.
Technical scheme of the present invention is: plate-typed draw ring used for connecting draw rods on tunnel metal support is made of a bar steel plate that is weldingly fixed on both ends boring on the metallic supports in galleries of installing the pull bar position, this bar steel plate is weldingly fixed on the interior contoured surface of the metallic supports in galleries shaped steel of installing the pull bar position or the outer surface, the center line of the center line on the bar steel plate between the hole, both ends and metallic supports in galleries shaped steel overlaps, and the hole site, both ends is positioned at outside weld metallic supports in galleries shaped steel and the bar steel plate contact surface on the bar steel plate.
The invention has the beneficial effects as follows: the plate-typed draw ring used for connecting draw rods on tunnel metal support reliable in structure, contact surface and the weld seam total length of board-like draw ring and metallic supports in galleries shaped steel are large, this board-like draw ring device intensity is high, bearing capacity greatly, not fragile.Metallic supports in galleries is used mass action and the supporting effect that board-like draw ring can improve metallic supports in galleries, realizes better the stable of tunnel.
Description of drawings
Accompanying drawing is the schematic diagram of plate-typed draw ring used for connecting draw rods on tunnel metal support embodiment.
1. bar steel plates among the figure, 2. end hole, 3 metallic supports in galleries shaped steel, 4. center lines.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
In the accompanying drawings, plate-typed draw ring used for connecting draw rods on tunnel metal support is made by a bar steel plate (1) that is weldingly fixed on both ends borings (2) on the metallic supports in galleries of installing the pull bar position, this bar steel plate (1) is weldingly fixed on the interior contoured surface of metallic supports in galleries shaped steel (3) or outer surface of installing the pull bar position, center line (4) between the upper hole, both ends (2) of bar steel plate (1) and the center line (4) of metallic supports in galleries shaped steel (3) overlap, and the upper position, hole, both ends (2) of bar steel plate (1) is positioned at outside bar steel plate (1) and weld metallic supports in galleries shaped steel (3) contact surface.
Claims (1)
1. plate-typed draw ring used for connecting draw rods on tunnel metal support, mainly consisted of by a bar steel plate that is weldingly fixed on both ends boring on the metallic supports in galleries of installing the pull bar position, it is characterized in that: this bar steel plate is weldingly fixed on the interior contoured surface of the metallic supports in galleries shaped steel of installing the pull bar position or the outer surface, the center line of the center line on the bar steel plate between the hole, both ends and metallic supports in galleries shaped steel overlaps, and the hole site, both ends is positioned at outside weld metallic supports in galleries shaped steel and the bar steel plate contact surface on the bar steel plate.
