Abstract
A kind of underground coal mine clashes canopy supporting beam, it adopts Plate Welding to become cross sectional shape to be the i beam of " mouth " font, and main carrier bar shutoff will be made up of ultra high molecular polyethylene material in the inner space of i beam, it is lower that the utility model has cost, be conducive to environmental protection, the beam be made up of supra polymer material completely can be overcome and there is the fire-retardant defect poor with antistatic property.
Description
Technical field
The present invention relates to a kind of steel structure member, be specifically related to a kind of supporting beam, particularly relate to underground coal mine and clash canopy supporting beam.
Background technology
Well-known: underground coal mine is clashed canopy supporting beam and generally adopted round log or half round timber, on the one hand, round log needs to consume a large amount of forest reserves; be unfavorable for environmental protection, meanwhile, usually can there is pressure break in round log, fracture situation; usually need to upgrade, thus its use cost is also higher.For a change this defect, Chinese utility model patent number for " 200720039253.5 " patent name be that " underground mine use clashes capplce " discloses the underground mine use that a kind of macromolecular material makes and clash capplce, existing wooden canopy supporting beam is in an opposite direction replaced with this, although this kind of supporting beam has lower-cost, the advantage that application life is longer, but, due to anti-flammability and antistatic in poor-performing, be unfavorable for the safety in production of underground coal mine, although also there is the situation adopting steel supporting beam at present, but adopt steel supporting beam to have the higher defect of cost completely, and overall weight is heavier, be unfavorable for installing and using.
Summary of the invention
The object of the invention is to: clash the above-mentioned defect existing for capplce for existing underground mine use, the present invention proposes a kind of novel underground coal mine and clashes canopy supporting beam, overcomes existing underground coal mine and clashes defect existing for canopy supporting beam.
The present invention realizes the technical scheme that above-mentioned purpose adopts: adopt Plate Welding to become cross sectional shape to be the i beam of " mouth " font, and by main carrier bar shutoff in the inner space of i beam, described main carrier bar is made up of ultra high molecular polyethylene material.
Beneficial effect: the present invention is due to after employing said method, because main carrier bar is made up of nonmetal macromolecular material, and can profit be repeated, have the lower environmentally friendly advantage of cost, the i beam be made up of steel plate, by totally-enclosed for main carrier bar parcel, not only further enhances total supporting capacity of beam, simultaneously, because metal material has fire-retardant and anlistatig good characteristic, so, the beam be made up of supra polymer material completely can be overcome and there is the fire-retardant defect poor with antistatic property.

Fig. 2 is the A-A view of Fig. 1;
Shown in figure: 1 is i beam; 2 is main carrier bars.
Detailed description of the invention
A kind of underground coal mine of the present invention clashes canopy supporting beam, it is made up of i beam (1) and main carrier bar (2), described i beam (1) becomes cross sectional shape to be " mouth " font by Plate Welding, main carrier bar (2) is totally-enclosed in i beam (1) inner space, and described main carrier bar (2) is made up of ultra high molecular polyethylene material.
In concrete manufacturing process, in advance ultra high molecular polyethylene raw material powder is put into mould, main carrier bar (2) is made under high-temperature high-pressure state, i beam (1) reserves an opening in advance, by the sharp processing of main carrier bar (2) size that extremely main carrier bar (2) internal closed space is slightly large, use opening press-in i beam (1) inner space that hydraulic press or the just main carrier bar (2) of other press reserve from i beam (1), now, the opening Plate Welding shutoff that i beam (1) is reserved in advance.
Claims (1)
1. a underground coal mine clashes canopy supporting beam, it is made up of i beam (1) and main carrier bar (2), it is characterized in that: i beam (1) becomes cross sectional shape to be " mouth " font by Plate Welding, main carrier bar (2) is totally-enclosed in i beam (1) inner space, and main carrier bar (2) is made up of ultra high molecular polyethylene material.
