Fig. 1 is the integral position schematic diagram in tread of the present utility model air channel;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of concrete bracket built-in fitting node of the present utility model;
In figure: the top board of 1-subway station, 2, drop in beam under 4-left and right concrete bracket, 3-prefabricated tread air channel base plate, 5-angle steel, 6-steel plate, 7-cement mortar joint filling preset clearance, 8-mortar sloping layer, 9-train operation tread absolute altitude, 10-platform plate, 11-subway station base plate, 12-station top board longeron, 13-elongated weld seam.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described.In Fig. 2,3, tread air channel, described a kind of improved semi-precast underground railway station, it is characterized in that: the square duct that under Shi You subway station, described tread air channel top board 1, left and right concrete bracket, drop in beam 2,4 and prefabricated tread air channel base plate 3 form, under described left and right concrete bracket, drop in beam 2,4 is directly watered and is built up an integral body by concrete and subway station top board 1, and under described left and right concrete bracket, drop in beam the 2, the 4th, forms respectively after the reinforcing bar binding by its inner reinforcing bar and subway station top board 1 inside after concreting again.Under left and right concrete bracket, the bracket position of drop in beam 2,4 is embedded with angle steel 5, the steel plate 6 of prefabricated tread air channel base plate 3 by being embedded in its two side bottom respectively with left and right concrete bracket under angle steel 5 welding on drop in beam 2,4.The described steel plate 6 that is embedded in base plate 3 bottoms, prefabricated tread air channel has four, is embedded in respectively the position in 3 four bights of base plate, prefabricated tread air channel.
As shown in Figure 2, at air channel prefabricated panel 3 end faces, being provided with the gradient is 1% mortar sloping layer 8.For preventing current direction platform plate 10 shielding reveals on tread air channel prefabricated panel 3, using P42.5 cement mortar to carry out the gradient at air channel prefabricated panel 3 end faces is that 1% mortar looks for domatic to become mortar sloping layer 8, the high side of mortar sloping layer 8 absolute altitudes is near platform plate, at shielding reveal, allow in tread air channel water in that side flow discharge away from platform plate 7 shield doors.
As shown in Figure 3, for convenience of tread air channel prefabricated panel 3, install, respectively and under left and right concrete bracket, between drop in beam 2,4, be provided with the cement mortar joint filling preset clearance 7 of 40-60mm, air channel prefabricated panel 3 is installed and is used P42.5 cement mortar to carry out filleting to 40-60mm cement mortar joint filling preset clearance 7 after welding to tamp processing at the two ends of described prefabricated tread air channel base plate 3.
During the utility model Specific construction: drop in beam 2,4 positions under reserved left and right concrete bracket during station top board 1 template construction at top AT STATION, drop in beam 2 reinforcing bars under colligation concrete bracket, the pre-buried L75mmx75mmx10mm angle steel 5 of the bracket position of drop in beam 2,4 difference under left and right concrete bracket, after reinforced bar engineering inspection of quality is qualified, seal drop in beam 2,4 templates under left and right concrete bracket, top, the station top board 1 one cast at drop in beam 2,4 and place, place, tread air channel under left and right concrete bracket.Specifically building is the concrete of drop in beam under Pouring concrete at the same time bracket in subway station top board 1 and station top board longeron 5 casting process, when concreting, first build the concrete of drop in beam 2,4 under the left and right concrete bracket in air channel, Deng the concrete of station, the lower fast initial setting time placement layer by layer top of drop in beam concrete top board 1, prevent from, because top board 1 concrete pressure in station causes too greatly lower drop in beam 2, the problems such as mould burst-mode occur to run.The maintenance 14 days of sprinkling water after concreting, etc. 2,4 concrete strengths of drop in beam under left and right concrete bracket, reach after design strength, the 10 ton forklift mounting rails that special bracket is equipped with in use are road prefabricated panel 3 against the wind, after prefabricated panel 3 installation sites in tread air channel are adjusted, pre-buried angle steel 5 on drop in beam 2,4 under the pre-buried steel plate 6 in tread air channel prefabricated panel 3 bottoms, two ends and left and right concrete bracket is carried out to elongated weld seam and be welded and fixed.The position at every tread air channel prefabricated panel 3 four angles, bottom is pre-buried block specifications 100mm * 150mm * 10mm steel plate 6 respectively, and the gap of installing between rear two prefabricated panels 3 is 2mm, and weld bead height is 10mm.
Precast plate installation bracket of the present utility model, adopt 180mm*70mm*90mm and two kinds of model channel-section steel welding production growth 1650mm of 100mm*48mm*5.3mm, wide 120mm, the precast plate installation bracket of height 3750mm, bracket props up and drags the platform of precast plate to adopt the inclined-plane setting that becomes 30 degree angles with horizontal plane, is beneficial to prefabricated cover plate jacking and installs.The wire rope that install on bracket top is connected by the pre-buried suspension ring of shackle and precast plate, prevents from, in prefabricated cover plate transportation, falling accident occurs.Utilize fork truck conveniently moving and lifting to lift the feature of function, precast plate installation bracket is arranged on 10T fork truck, every 40 minutes, a prefabricated panel is installed, and installation process safety high speed, has shortened the duration, has reduced construction cost.
