Detailed description of the invention
Referring to Fig. 1, steel structure platform of the present utility model is provided with steel floor 1, girder steel 2 and steel column 3. Every layer of steel floor 1 is planar structure, plurality of steel plates block welding form (attached not shown), is supported on girder steel 2 (being welded to connect with girder steel 2). Steel plate block can be checkered steel plate or general steel plate, and thickness is generally 4��8 millimeters, it is desirable to is 5��6 millimeters. For increasing the rigidity of steel floor 1, it is also possible to weld ribbed stiffener thereon, figure is slightly. Steel column 3 arranges 4, and girder steel 2 arranges many. The two ends being positioned at the girder steel 2 of surrounding are welded on steel column 3, and the two ends of centrally located girder steel 2 are welded on the girder steel 2 of surrounding. Steel column 3 is by steel floor 1 traverse, and steel floor 1 is provided with 1 pipeline hole 5, and steel floor 1 is connected with descending stair 8 and up stair 9.
Steel floor 1 is provided with steel column hole 30 around steel column 3, is welded with steel column hole steel pipe 31 (referring to Fig. 1 and Fig. 3), steel column hole 30 and steel column hole steel pipe 31 around steel column hole 30 and is 4. Referring to Fig. 1 and Fig. 4, it is welded with 1 pipeline hole steel pipe 51 around pipeline hole 5; As shown in Figure 4, pipeline 50 passes from pipeline hole 5 and pipeline hole steel pipe 51. Steel floor 1 is welded with 1 transition cofferdam 7 at the stairs port near zone of descending stair 8, and the marginal area in other region is welded with floor cofferdam 4. Near being welded with additional floor cofferdam 41 between steel column hole steel pipe 31 and the one end in transition cofferdam 7 of the stairs port of descending stair 8, the other end in transition cofferdam 7 and floor cofferdam 4 are welded to connect. Described welding (including the welding between steel plate block) is continuous welding. Floor cofferdam 4 and additional floor cofferdam 41 are made by rectangle steel plate, and Fig. 2 illustrates part floor cofferdam 4. Transition cofferdam 7 is made up of steel plate, and its shape of cross section is generally herringbone (as shown in Figure 6) or circular arc (as shown in Figure 7). Transition cofferdam 7 should both be beneficial to personnel and pass through, and can prevent again the flammable liquid of leakage from flowing to descending stair 8.The stairs port of up stair 9 need not arrange transition cofferdam, arranges floor cofferdam 4. Connection between steel column hole steel pipe 31 and the floor cofferdam 4 of the stairs port of up stair 9, and floor cofferdam 4 self connection around the corner, be and be welded to connect continuously. Floor cofferdam 4, transition cofferdam 7, additional floor cofferdam 41, steel column hole steel pipe 31 and pipeline hole steel pipe 51 are respectively positioned on above steel floor 1, and their height is generally 100��400 millimeters, it is desirable to be 150��250 millimeters. Railing 10 can be set in the outside in floor cofferdam 4 and the both sides of descending stair 8 and up stair 9, to ensure personal security.
A kind of preferred version of the present utility model is, steel floor 1 is from side to the opposite side tilted upward setting relative with this side, the formation gradient (needing the height adjusting each girder steel 2 at diverse location for this); The described gradient is generally 0.5%��5%, it is desirable to be 2%��3%. As it is shown in figure 1, by the direction of big hollow arrow indication, steel floor 1 tilts gradually downward. Referring to Fig. 1 and Fig. 5, the lower position at steel floor 1 is provided with ground small opening 6, is welded with discharging tube 61 around ground small opening 6, and the bottom of discharging tube 61 is connected with the welded top of sump oil pipeline 62. Described welding is continuous welding, discharging tube 61 and sump oil pipeline 62 and is respectively positioned on below steel floor 1. Leakage rate according to flammable liquid, the steel floor 1 of every 100 square metres generally arranges 2��3 ground small opening 6 (being provided that 2 shown in Fig. 1), and discharging tube 61 and sump oil pipeline 62 are correspondingly respectively provided with 2��3. Adopt such scheme of the present utility model, the flammable liquid leaked on steel floor 1 can be made to flow to relatively low position, and drain through ground small opening 6, discharging tube 61 and sump oil pipeline 62, it is prevented that flammable liquid hydrops too much, liquid layer higher and from floor cofferdam 4, transition cofferdam 7, additional floor cofferdam 41, steel column hole steel pipe 31 and pipeline hole steel pipe 51 flow out.
The shape of steel column hole 30 described in the utility model, pipeline hole 5 and ground small opening 6 and the shape of cross section of steel column hole steel pipe 31, pipeline hole steel pipe 51, discharging tube 61 and sump oil pipeline 62, it is possible to be circular or square.
