Abstract
The utility model provides a U-shaped steel bracket manufactured by a waste steel rail, comprising an arch-shaped section, and left and right bracket legs, wherein the left and right bracket legs are respectively fixed at the left and right end parts of the arch-shaped section. The U-shaped steel bracket disclosed by the utility model has the advantages of great supporting strength, good supporting effect, simple construction process and shortened construction period.
Description
Technical field
The utility model relates to a kind of suspension device for the tunnel, is specifically related to support used in a kind of mine working.
Background technology
When the tunnel of constructing very broken, adopt general suspension device such as bolt support, bolting with wire mesh, spray anchor net combined supporting texts relatively poor, the supporting effect of log hut supporting is better, but the log hut supporting is perishable, As time goes on, the strength decreased of log hut supporting, and log hut supporting workload in work progress is large, long construction period.
The utility model content
The purpose of this utility model provides the U-shaped steel bracket that a kind of waste and old steel rail is made, and its supporting intensity is large, effective, and work progress is simple.
For achieving the above object, technical solution of the present utility model is:
The U-shaped steel bracket that a kind of waste and old steel rail is made comprises arcuate segment and left and right rack leg, and described left and right rack leg is individually fixed in the left and right both ends of described arcuate segment.
The U-shaped steel bracket that the utility model waste and old steel rail is made, wherein, the left and right both ends of described arcuate segment are welded with respectively left and right steel plate, described left and right rack leg upper end is welded with respectively first, second steel plate, all have bolt hole on above-mentioned each steel plate, left plate on the described arcuate segment is connected by the bolt that is arranged in the described bolt hole with the first steel plate on the described left socle leg, and the right steel plate on the described arcuate segment is connected by being arranged at described bolt hole inner bolt with the second steel plate on the described right support leg.
The U-shaped steel bracket that the utility model waste and old steel rail is made, wherein, described left and right rack leg bottom is fixed with respectively left and right supporting steel plate.
After adopting such scheme, the U-shaped steel bracket that the utility model waste and old steel rail is made comprise arcuate segment and the left and right rack leg of steel, so supporting intensity is large, supporting effect is good, and work progress is simple, shortens construction period.
Description of drawings
Fig. 1 is the front view of the U-shaped steel bracket of the utility model waste and old steel rail making;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Specify the U-shaped steel bracket that the utility model waste and old steel rail is made below in conjunction with accompanying drawing.
The specific embodiment
Such as Fig. 1, shown in 2, the U-shaped steel bracket that the utility model waste and old steel rail is made, comprise arcuate segment 1 and a left side, right support leg 2,3, arcuate segment 1 left side, right both ends are welded with respectively a left side, right steel plate, left, right support leg 2,3 upper ends are welded with respectively first, the second steel plate, all have four bolts hole on above-mentioned each steel plate, left plate on the arcuate segment 1 is connected by four bolts with the first steel plate on the left socle leg 2, four bolts are arranged at respectively in four bolts hole of steel plate, right steel plate on the arcuate segment 1 is connected by four bolts with the second steel plate on the right support leg 3, four bolts are arranged at respectively in four bolts hole of steel plate, left, right support leg 2,3 bottoms are welded with respectively left supporting steel plate 21 and right supporting steel plate 31, arcuate segment 1 adopts waste and old steel rail to be processed into arc with point switch, left, right support leg 2, the 3 same waste and old steel rails that adopt are made, the refuse secondary is utilized, and easy to process, cost of production is low.
The above embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
