Abstract
A kind of metro platform shield door insulation column, comprise be made up of polymer composite column section, metal inner lining stiffening plate on column section inwall or metal inner lining reinforced tube, column section inner chamber polymeric filler, corrosion-resistant steel column wrapper sheet, the composite material back sheet at the corrosion-resistant steel column wrapper sheet back side, the nylon adherent buckle of vertical columns wrapper sheet, column top attaching parts, tread air channel beam, column bottom attaching parts, concrete station platen.Metal inner lining stiffening plate or metal inner lining reinforced tube rear interior cavity perfusion polymeric filler in column section inner surface heat compound, the top of column section is fixed on the beam of tread air channel by column top attaching parts, its underpart is fixed on concrete station platen by column bottom attaching parts, the hot composite material back sheet in the corrosion-resistant steel column wrapper sheet back side, is fixed on column section with nylon adherent buckle.The utility model ground insulation is resistor satisfied >=designing requirement of 0.5M Ω, eliminate the potential safety hazard that shielded gate body insulation nonconformity produces.
Description
Technical field
The utility model relates to subway, city rail shielded gate, particularly relates to a kind of metro platform shield door insulation column.
Background technology
Along with Construction of Urban Rail Traffic such as China's subway, light rails, more and more higher to the security requirement of subway and city rail.The screen door that subway and city rail platform are installed, platform and train running interval are separated, railcar does the wire effect of current reflux with track, on such subway train, platform just there is difference of potential with the earth in shielded gate, when passenger and driver and conductor pass in and out train door and platform screen door, form step voltage.
The requirement of current basis " urban track traffic design regulation ", each subway and city rail project generally adopt whole side shielded gate door body structure to be connected with rail with equipotential cable with after civil engineering structure insulating mounting.This processing method can ensure the safety of passenger in theory, but due to the impact of various factors in Practical Project is implemented, at home also without any a subway line can accomplish to shield the ground insulation of every body resistor satisfied >=designing requirement of 0.5M Ω.That is each subway line is all in operation with certain potential safety hazard.Shielded gate column is the body junction component of shielded gate, is the framework of other parts of carrying shielded gate, and therefore the quality of shielded gate column insulating power is key factors of the whole door body structure insulation of impact.
Utility model content
The technical problems to be solved in the utility model is, a kind of shielded gate insulation column is provided, and ground insulation resistance is stablized, all can not owing to there is electrically conducting with the mechanical erection of column in all parts being arranged on the metro platform shield door on insulation column, to ensure the ground insulation requirement reaching metro platform shield door, when preventing passenger from contacting shielding every body with driver and conductor, there is electric shock phenomenon.
The technical scheme adopted is:
A kind of metro platform shield door insulation column, comprise be made up of polymer composite column section, metal inner lining stiffening plate on column section inwall or metal inner lining reinforced tube, column section inner chamber polymeric filler, corrosion-resistant steel column wrapper sheet, the composite material back sheet at the corrosion-resistant steel column wrapper sheet back side, the nylon adherent buckle of vertical columns wrapper sheet, column top attaching parts, tread air channel beam, column bottom attaching parts, concrete station platen.The column section inner surface heat compound that described polymer composite is formed pours into column section inner chamber polymeric filler after metal inner lining stiffening plate or metal inner lining reinforced tube, the top of column section is fixed on the beam of tread air channel by column top attaching parts, the bottom of column section is fixed on concrete station platen by column bottom attaching parts, and the hot compound in the corrosion-resistant steel column wrapper sheet back side is fixed on column section surface by nylon adherent buckle after composite material back sheet.
Two lobes of above-mentioned nylon adherent buckle are bonded in the relevant position of the composite material back sheet at column section surface and the corrosion-resistant steel column wrapper sheet back side respectively.
Above-mentioned column top attaching parts is processed by carbon steel, and surface has airtight coated composite insulating material layer, and has the retractor device absorbing civil engineering sedimentation.
Above-mentioned column bottom attaching parts is processed by carbon steel, and surface has airtight coated composite insulating material layer.
The good effect that the utility model obtains:
1, the upper and lower part attaching parts of subway shield side wall outer panel is directly connected with tread air channel beam and concrete station platen civil engineering structure, does not need to do insulation processing again, the mounting process of shielded gate is simplified greatly;
2, platform screen door body there will not be insulation values to be less than the situation of 0.5 Μ Ω;
3, outward appearance does not change compared with the metro platform shield door of routine, and using function does not have
Change;
4, the potential safety hazard because shielding every body insulation nonconformity produces is eliminated.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the D--D section drawing of Fig. 1.
Detailed description of the invention
A kind of metro platform shield door insulation column, comprises the column section 1, metal inner lining reinforced tube 2, column section inner chamber polymeric filler 3, corrosion-resistant steel column wrapper sheet 4, the composite material back sheet 5 at the corrosion-resistant steel column wrapper sheet back side, the nylon adherent buckle 6 of vertical columns wrapper sheet, column top attaching parts 7, tread air channel beam 9, column bottom attaching parts 8, the concrete station platen (see figure 1) on column section inwall that are made up of polymer composite.Metal inner lining reinforced tube 2(in the column section 1 inner surface heat compound that described polymer composite is formed is so that be connected with miscellaneous part with bolt after punching tapping) pour into the rigidity that column section inner chamber polymeric filler 3(increases insulation column afterwards), the top of column section 1 is fixed on tread air channel beam 9 by column top attaching parts 7.Described column top attaching parts 7 is processed by carbon steel, and surface has airtight coated composite insulating material layer, and has the retractor device absorbing civil engineering sedimentation.The bottom of column section 1 is fixed on concrete station platen 10 by column bottom attaching parts 8.Described column bottom attaching parts 8 is processed by carbon steel, and surface has airtight coated composite insulating material layer.Composite material back sheet 5 in the hot compound in described corrosion-resistant steel column wrapper sheet 4 back side, be bonded in the relevant position of the composite material back sheet at column section surface and the corrosion-resistant steel column wrapper sheet back side again by two lobes of nylon adherent buckle 6 respectively, form a kind of metro platform shield door insulation column.
