Abstract
The utility model discloses a kind of pultruded steel core glass fiber reinforced plastic platform plate, comprise glass fiber reinforced plastic and draw casement material and landing slab steel core, landing slab steel core is inserted in glass fiber reinforced plastic and draws in the internal cavities of casement material, and glass fiber reinforced plastic draws the two ends of casement material to fill with to have in steel core is sealed in by sealing resin glue; Glass fiber reinforced plastic draws casement material to be laterally provided with some bolts, and bolt draws together with the two is fixed by casement material and landing slab steel core through glass fiber reinforced plastic, and bolt and glass fiber reinforced plastic draw the gap between casement material to fill with sealing resin glue.The utility model draws in casement material by landing slab steel core being penetrated glass fiber reinforced plastic, and be fixed with bolts and adopt resin glue to seal, so can improve anti-corrosion capability and the resistance to compression tensile strength of landing slab, without the need to processing mold, thus enhance productivity, reduce cost of production, be conducive to the safety in production of mine.
Description
Technical field
The utility model relates to mining tool equipment technical field, be specifically related to a kind ofly have trickle at colliery, metal mine etc., there was dampness in the air, dislike slightly environment containing soda acid composition or the solution that is corrosive etc. in water under the landing slab that uses.
Background technology
Because the glass fiber reinforced plastic platform plate used at present in the pit shaft of mine mainly contains mold pressing type and pultruded two kinds, mold pressing type adopts metal edge frame to be skeleton outsourcing glass fibre reinforced plastic structure, and making is hand pasting forming; At the external surface cover glass steel of steel.Because of the more and specification of every class of mine pit shaft and chemical metallurgy, city management equipment kind and shape variant, die needed corresponding more during making, each designing requirement is different in addition, and these moulds just can not be reused, as this increased cost of manufacture and cost of production.Hand sticks with paste glass fiber reinforced plastic ladder in use for some time in addition, and moisture can penetrate into component inside by the spilehole of glass fiber reinforced plastic surface and easily cause corrosion steel core inside, reduces holding capacity and safety factor.Although pultruded solves mould and reuses problem, owing to there is no included steel core, intensity is had a greatly reduced quality, reduce resistance to compression and the tensile strength of ladder.
Utility model content
For the deficiencies in the prior art, the utility model provides that a kind of structure is simple, intensity is high, the pultruded steel core glass fiber reinforced plastic platform plate of safe and reliable, long service life.
The purpose of this utility model is realized by following technological means: a kind of pultruded steel core glass fiber reinforced plastic platform plate, comprise glass fiber reinforced plastic and draw casement material and landing slab steel core, landing slab steel core is inserted in glass fiber reinforced plastic and draws in the internal cavities of casement material, and glass fiber reinforced plastic draws the two ends of casement material to fill with to have in landing slab steel core is sealed in by sealing resin glue.
Further, glass fiber reinforced plastic draws casement material to be laterally provided with some bolts, and bolt draws together with the two is fixed by casement material and landing slab steel core through glass fiber reinforced plastic, and bolt and glass fiber reinforced plastic draw the gap between casement material to fill with sealing resin glue.
The utility model draws in casement material by landing slab steel core being penetrated glass fiber reinforced plastic, and be fixed with bolts and adopt resin glue to seal, so can improve anti-corrosion capability and the resistance to compression tensile strength of landing slab, without the need to processing mold, thus enhance productivity, reduce cost of production, be conducive to the safety in production of mine.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is A-A sectional view in Fig. 1.
In figure, 1-glass fiber reinforced plastic draws casement material 2-landing slab steel core, 3-bolt.
Detailed description of the invention
In the present embodiment, see figures.1.and.2, described pultruded steel core glass fiber reinforced plastic platform plate, comprise glass fiber reinforced plastic and draw casement material 1 and landing slab steel core 2, landing slab steel core 2 is inserted in glass fiber reinforced plastic and draws in the internal cavities of casement material 1, and glass fiber reinforced plastic draws the two ends of casement material 1 to fill with to have in landing slab steel core 2 is sealed in by sealing resin glue.
Glass fiber reinforced plastic draws casement material 1 to be laterally provided with some bolts 3, and bolt 3 draws together with the two is fixed by casement material 1 and landing slab steel core 2 through glass fiber reinforced plastic, and bolt 3 and glass fiber reinforced plastic draw the gap between casement material 1 to fill with sealing resin glue.
Major performance benefit of the present utility model is as follows:
1. physical and mechanical properties:
Specific strength is high: glass fiber reinforced plastic specific strength is 1666Mpa (g/cm), and steel specific strength is 521.8MPa (g/cm), and glass fiber reinforced plastic is more than 3 times of steel.
Abrasion resistance is good: add a certain proportion of high-abrasive material on landing slab surface during making, improves 3-20 doubly than A3 steel abrasion resistance.
Anti-electrostatic fire retardant: admixture antistatic additive, fire proofing can remove electrostatic, and reach from ceasing fire resistance.
Cold-resistant heat insulation: can not bursting by freezing at Frozen Medium less than-60 DEG C drawing and extruding section bars, heatproof 120 DEG C, coefficient of thermal conductivity is 0.5% of steel.
Resistance to compression is large: rigidity reaches more than 8400MPa.
Toughness is high: have the performance 50J/cm that toughness high impact forces is large, absorbs energy by plastic strain.
Lightweight: glass fiber reinforced plastic density 1.5-1.9g/cm3 is 1/4 of steel, than metal light, easy transportation and installation.
2. chemical resistance:
Glass fiber reinforced plastic has excellent corrosion resistance, and when carrying or store Korrosionsmedium, higher than common iron several times of its application life arrives decades of times.
3. easy for installation, safety and maintenance cost low:
Pultruded steel core glass fiber reinforced plastic platform plate connected mode adopts snap joint, and be easy to transport and install, corrosion resistance is strong, without the need to carrying out surface anticorrosion process, and easy to maintenance.
