Product introduction of profiled steel supports/shaped steel sheds
Profiled steel supports are mainly used in mine tunnels, It is used for secondary support of mine tunnels and support of mountain tunnels. The use of steel brackets can effectively reduce the occurrence of roof collapse, collapse and other accidents. It is safe and reliable and improves the stability of the mine ventilation system. The use of steel retractable brackets better solves the problem of excavation support.
Main Features
It has the characteristics of high pressure resistance, long support time, easy installation and not easy to deform.
Main uses
Mainly used for mine tunnels, secondary support of mine tunnels, and support for mountain tunnels.
Specifications of profiled steel brackets
As the main profiled steel used in manufacturing tunnel retractable metal brackets, profiled steel is widely used at home and abroad.
However, due to inconsistent understanding of the performance and requirements of section steel itself, the cross-sectional shape, geometric parameters and materials of section steel vary from country to country.
There are four main types of section steel produced in my country: Among them, the first two are products of the era and are positioned at the waist. The latter two are products of the era and are positioned at the ears. Due to its low carrying capacity, it is rarely produced.
Composition of profile steel bracket
Profile steel bracket is composed of the following structures: top beam, column legs, connectors, inter-frame tie rods, and backing materials.
Among them, the column legs have three forms. 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 a radius of curvature. A base is welded under the column legs, and the size of the base depends on the softness and hardness of the bottom plate. The top beam is arc-shaped, and 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. The connector is a clamping device between the bracket sections. It can connect the sections. It can also compress the joints of the two connected sections of steel to provide pre-tightening force so that there is friction between the section steels, thereby ensuring that the arch The shaped bracket has a certain working resistance and a certain shrinkage.
