Abstract
The invention discloses a supporting beam of an underground coal mine proping up framed timber. The supporting beam is an H-shaped beam formed by welding a steel plate, the cross section of the H-shaped beam is square, and a main bearing beam made of an ultrahigh molecular polyethylene material blocks the interior space of the H-shaped beam. The supporting beam is low in cost, friendly to the environment and capable of overcoming the poor inflaming retarding and anti-static performance of a beam completely made of an ultrahigh molecular material.
Description
Technical field
The present invention relates to a kind of steel structure member, be specifically related to a kind of supporting beam, relate in particular under coal mine canopy supporting beam in an opposite direction.
Background technology
Well-known: under coal mine, canopy supporting beam generally adopts round log or half round timber in an opposite direction, and on the one hand, round log need to consume a large amount of forest reserves; be unfavorable for environmental protection, meanwhile, usually can there is pressure break in round log, situation fractures; usually need to upgrade, thereby its use cost is also higher.This defect for a change, Chinese utility model patent number is that " 200720039253.5 " patent name is clashed capplce for " underground mine use is clashed capplce " announced a kind of underground mine use made from macromolecular material, with this, replace existing wooden canopy supporting beam in an opposite direction, although this kind of supporting beam has lower-cost, the advantage that application life is longer, but, due to anti-flammability and antistatic aspect poor-performing, be unfavorable for the safety in production under coal mine, although also there is the situation that adopts steel supporting beam at present, but adopt steel supporting beam to there is the defect that cost is higher completely, and overall weight is heavier, be unfavorable for installing and using.
Summary of the invention
The object of the invention is to: for existing underground mine use, clash the existing above-mentioned defect of capplce, the present invention proposes under a kind of novel coal mine canopy supporting beam in an opposite direction, overcome under existing coal mine the existing defect of canopy supporting beam in an opposite direction.
The present invention realizes the technical scheme that above-mentioned purpose adopts: adopting Plate Welding to become cross sectional shape is the i beam of " mouth " font, and by main carrier bar shutoff in the inner space of i beam, described main carrier bar is to be made by ultra high molecular polyethylene material.
Beneficial effect: the present invention is owing to adopting after said method, because main carrier bar is to be made by nonmetal macromolecular material, and can repeat profit, have the lower environmentally friendly advantage of cost, the i beam of being made by steel plate, by the totally-enclosed parcel of main carrier bar, has not only further been strengthened total supporting capacity of beam, simultaneously, because metal material has fire-retardant and anlistatig good characteristic, so, can overcome the beam of being made by supra polymer material completely and have defect fire-retardant and that antistatic property is poor.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the A-A view of Fig. 1;
Shown in figure: the 1st, i beam; The 2nd, main carrier bar.
The specific embodiment
Under a kind of coal mine of the present invention, clash canopy supporting beam, it is comprised of i beam (1) and main carrier bar (2), described i beam (1) is that by Plate Welding, to become cross sectional shape be " mouth " font, main carrier bar (2) is totally-enclosed in i beam (1) inner space, and described main carrier bar (2) is to be made by ultra high molecular polyethylene material.
In concrete manufacturing process, in advance ultra high molecular polyethylene raw material powder is put into mould, under high-temperature high-pressure state, make main carrier bar (2), i beam (1) reserves an opening in advance, by the sharp processing of main carrier bar (2) to the slightly large size in main carrier bar (2) enclose inside space, an opening that uses hydraulic press or the just main carrier bar of other press (2) to reserve from i beam (1) is pressed into i beam (1) inner space, now, opening Plate Welding shutoff i beam (1) being reserved in advance.
Claims (1)
1. under a coal mine, clash canopy supporting beam, it is comprised of i beam (1) and main carrier bar (2), it is characterized in that: i beam (1) is that by Plate Welding, to become cross sectional shape be " mouth " font, main carrier bar (2) is totally-enclosed in i beam (1) inner space, and main carrier bar (2) is to be made by ultra high molecular polyethylene material.
