Now we will introduce to you a kind of mining support material produced by our company, the steel bracket!
Shaped steel brackets are widely used in secondary support of mine tunnels and mine tunnels in mountain tunnels.
The profiled steel bracket has many advantages, including greater bearing capacity, longer support time, easy installation and resistance to deformation. It has better toughness than other steel sections, has shrinkability and stable and reliable load-bearing capacity. Adapt to the load and deformation of soft surrounding rock. The section utilization rate is high, the bracket is easy to support and return, and the maintenance amount is small. The bracket has high recycling and reuse rate, reduces the use of pit wood, and has obvious environmental benefits.
The steel bracket is a kind of passive support with high tensile strength and tensile strength. It also has good toughness and initial support. It has high strength, high support strength, can be used multiple times, and is widely used in mine tunnels, especially in deep complex tunnels and soft coal seam tunnels. The selection of steel brackets has solved the problem of excavation support very well.
The uniquely designed top beam of the circumferential steel is in the shape of an arc. Its number can be divided into sections or multiple sections depending on the size of the tunnel section, the stress on the bracket, and the transportation conditions. Column legs. There are three types of column legs. One is that the upper part is arc-shaped and the lower part is a straight segment. The second is that they are all curved and have only one radius of curvature. The third is that they are all curved but have two radii of curvature. There is a base welded under the column legs. The size of the base depends on the softness and hardness of the bottom plate. The connector is a clamping device between the bracket sections. It can connect the sections and can also connect the two connected steel joints. Compression provides pre-tightening force so that there is friction between the steel sections, thereby ensuring that the arched bracket has a certain working resistance and a certain amount of shrinkage. Interrack tie rod. The function of the tie rods between the racks is to enhance the overall relative stability of the brackets and connect the brackets longitudinally to form a whole. Backing material.
Models of profiled steel brackets include profiled steel brackets, profiled steel brackets, and profiled brackets. Customers can choose according to different models and can be processed and customized according to the models provided by customers. Our company strives for survival on quality, on the principle of credibility, and on the purpose of reasonable prices. , has won praise from a large number of new and old customers. The steel brackets produced by our company are exported to Middle East countries. Welcome new and old customers to visit and discuss business!
