Problems solved by technology
[0004] In the process of using the M-shaped steel, it needs to be used in conjunction with the anchor rod, and in different working environments, the matching point between the M-shaped steel and the anchor rod needs to be adjusted appropriately, and most of the existing M-shaped steel and the anchor rod are connected by an anchor The anchor plate and the M-shaped steel are fixedly connected by multiple sets of bolts. When the position of the matching point needs to be changed, the staff needs to remove all the multiple sets of bolts connected between the anchor plate and the M-shaped steel to move the anchor. In the process of multiple installation and disassembly of discs and bolts, it is very easy to cause damage to the thread teeth, resulting in failure of the bolts. Retaining holes will cause the adjustment of the anchor plate to be unable to achieve stepless adjustment, only polarized adjustment, and the adjustment process is very cumbersome

The invention discloses a fabricated M-shaped steel structure with a sliding base and belongs to the field of M-shaped steel structures. According to the fabricated M-shaped steel structure with the sliding base, an M-shaped steel main body is fixedly connected with an anchor rod through an anchoring hole in the sliding base, and the sliding base can freely slide on the M-shaped steel main body sothat the M-shaped steel main body and the anchor rod can be freely connected; in order to enable the sliding base to freely move on the M-shaped steel main body conveniently, lock grooves are dug inthe two side walls of the M-shaped steel main body correspondingly, in order to reduce the situation that the strength of the M-shaped steel main body is lowered due to stress concentration caused bylock groove digging, a plurality of sets of reinforcing ribs are pre-buried in the lock grooves, through existence of the reinforcing ribs, the overall strength of the M-shaped steel main body is improved, and meanwhile the effect of increasing friction is realized for locking of the sliding base; and finally, a plurality of sets of connecting columns in the sliding base are coupled together through steel ropes, and thus each singe column is not prone to being broken or losing efficacy due to external force.
Description
technical field [0001] The invention relates to the field of M-shaped steel structures, in particular to an assembled M-shaped steel structure with a sliding base. Background technique [0002] M-shaped steel is a cross-sectional shape like M-shaped steel. Compared with traditional strip-shaped steel, the flexural performance, stiffness and tensile strength of M-shaped steel have been comprehensively improved, and the flexural section modulus of M-shaped steel is improved. 37 times, the steel strength is increased by about 70 times, and the hardening effect of the M-beam cold rolling process increases the tensile strength by 12%-15%. [0003] M-shaped steel is a new type of mine support material. M-shaped steel adopts coiled steel plates with a thickness of 3-5mm and a width of 180-320mm. M-shaped steel can be combined with various anchor rods to form an anchor plate support. M steel connects multiple anchor rods through M steel to form an overall load-bearing structure. M ...
