Steel beam fixing structure

Abstract

The invention discloses a steel beam fixing structure. The steel beam fixing structure comprises anchor rods, a welding bracket, a steel beam and bolts, wherein the anchor rods are suitable for beinganchored on the well wall; the welding bracket comprises a side plate, a flat plate, a vertical plate and stiffening ribs, the side plate is arranged along the well wall and connected with the anchorrods to be fixed to the well wall, the flat plate is connected to one side of the side plate, the vertical plate is vertically arranged on the flat plate and connected with the side plate, a first connecting hole is formed in the vertical plate, and the stiffening ribs are located on one horizontal side of the vertical plate and connected with the vertical plate and the flat plate correspondingly;the steel beam is arranged on the flat plate and located on the other horizontal side of the vertical plate, and a second connecting hole is formed in the steel beam; and the bolts penetrate throughthe first connecting hole and the second connecting hole correspondingly so as to connect the steel beam with the welding bracket. According to the steel beam fixing structure, the bearing capacity ofthe steel beam can be improved, and the safety of mounting construction is improved.

Description

technical field [0001] The invention relates to the field of mechanical structures for mine shaft equipment, in particular to a steel beam fixing structure. Background technique [0002] In the related art, the fixing structure between the steel beam and the well wall is mainly to open holes on the steel beam flange, and then connect with the angle steel supporting plate, and the angle steel supporting plate is fixed on the well wall through anchor rods. When the force of the channel steel beam increases, it is necessary to weld angle steel on the web of the steel beam, and the angle steel is flush with the wing plate of the steel beam, and then connected with the angle steel bracket by bolts. This fixed structure is often used when the steel beam is under small stress. [0003] However, with the improvement of mine capacity, especially in the hoisting shaft, the steel beams bear more and more stress. At this time, the angle steel support plate appears very thin, and it doe...

Problems solved by technology

[0003] However, with the improvement of mine capacity, especially in the hoisting shaft, the steel beams bear more and more stress. At this time, the angle steel support plate appears very thin, and it does not match the shape and size of the "tall" steel beams, which affects visual safety.

At the same time, the fixed structure of the upper and lower angle steel pallets is affected by the quality of the on-site construction. It is often necessary to ream the holes on the pallet or steel beams on site. Affected by the size of the angle steel, the size of the reaming holes is limited, difficult to install, and the on-site reaming is also greatly The bearing capacity of the supporting plate and the steel beam is reduced, so that the installation quality cannot be guaranteed

In addition, due to the on-site electric welding and reaming in the underground, the construction progress is seriously affected, and it is not conducive to the safety of the constructors.
