Steel frame U25 U25 U25 steel bracket steel bracket characteristic sales U25 U25 steel bracket steel bracket Profile Products U-shaped steel bracket is kind of like the English letter "U" steel cross-sectional shape. States produced U-shaped steel cross-sectional shape, geometric parameters and material and so different. U25 steel bracket with a high setting load, high supporting strength, easy to install, easy to deformation, etc., so often used in the manufacture of the roadway retractable metal stents, as mine tunnel, the mine tunnel secondary support, and the support of the tunnel mountains branch care and other purposes. zmjt15 U25 U25 steel bracket steel bracket main features to withstand pressure, supporting a long time, easy to install easy deformation characteristics. U25 steel support shield in cross Mining Roadway Crossing Point application, and achieved remarkable results. Selection U25 steel bracket may yield support, better way to solve the problem of tunneling support. U25 steel support bracket with a scalable and reliable carrying capacity than other rigid support, adapt load and deformation, soft rock section utilization high, easy to stand back support, a small amount of maintenance, support recovery rate of reuse, reduce pit prop use, environmental benefits are clear. U25 steel bracket Features 1. top beam. Arc arched roof beams, the number depending on the size of the roadway, stand by force, different conditions of carriage have a multi-section of the points. 2. The column legs. There are three kinds of forms of column legs, the upper part of a circular arc, the lower part of straight line segments; second is all curved, and only one radius of curvature; third is all curved, with two curvatures radius. Column leg below the bottom plate is welded depending on the size of hard and soft base, the base may be; 3 connections. Connector is a holding device between the bracket Festival and the Festival can play a role in connecting section between two steel can also be connected to the joint portion of the compression, providing preload, having friction between the U-shaped steel, so as to ensure arch support has some resistance and some may work shrinkage. The frame between lever. The role of inter-frame drawbar is to enhance the overall relative stability of the stent, the stent from the longitudinal join together to form a whole. 5. backing material. The backing material is a filler material between the U-shaped steel brackets and rock, with the aim is to make the U-shaped steel brackets and rock close contact, to improve the situation by force stand to improve its carrying capacity and maintain the stability of the surrounding rock. U-shaped steel bracket design must be properly calculated, and when in use should be reasonable, in order to ensure mine safety and economic efficiency. The product has been exported to many countries, the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran, etc., unanimous praise.
