Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.If Fig. 5 is former constructing structure schematic diagram, under prior art condition of construction, by former built-in fitting 11 is fixed on former pillar 10, former built-in fitting 11 is also that symmetrical interval is arranged, again former shelf bracket 12 is fixed on former built-in fitting 11, in existing construction, the upper surface of former shelf bracket 12 is to be arranged to the inclined ramp parallel with case beam base plate.
Weld former main beam 13 in the upper surface of former shelf bracket 12, it is vertical with the upper surface of former shelf bracket 12 that former main beam 13 is welded on direction, and the many even intervals of former main beam 13 are arranged on former shelf bracket 12.The upper end of former main beam 13 forms an inclined-plane identical with former case beam 15 base plate angles, connects former longeron 14, then on former longeron 14, former base plate template 16 is installed on this inclined-plane, and fluid concrete, forms former case beam 15.
In prior art scheme, former shelf bracket 12, former main beam 13, former longeron 14 and the former base plate template 16 using is all after calculating, to process in advance, but at the scene in work progress, it between former main beam 13, former shelf bracket 12, former longeron 14 and former base plate template 16, is all oblique surface machining welding, such welding procedure difficulty is larger, expend in addition a large amount of manpower and materials, scene occurs that the probability of error is larger, adjusting is got up very difficult, is difficult to reach design and construction permissible accuracy.
Structure chart of the present utility model as shown in Fig. 1~2, shelf bracket 3 is fixed on pillar 1 by built-in fitting 2, the upper end of shelf bracket 3 is arranged horizontally, in the upper surface of shelf bracket 3, main beam 4 is set, the even interval of main beam 4 is arranged in the horizontal upper end face of shelf bracket 3, then at the horizontal upper end face weldable steel truss 5 of main beam 4.The object arranging is like this to be welded with to be in the horizontal direction beneficial to site operation, saves the working time, and handled easily has also strengthened the security reliability of site operation.
As shown in Fig. 3~4, described steel truss 5 is made according to the requirement of site operation, and lower end is the horizontal plane of laminating main beam 4, and upper end is inclined ramp, and the angle on inclined-plane is identical with the angle that case beam 8 base plates tilt.The steel truss 5 of field fabrication can reach the requirement of construction completely, case beam 8 base plates of more fitting, and steel truss 5 adjusting angles are also more convenient and accurate in addition, and the difficulty of construction reduces greatly, and the precision of construction has but promoted.
Steel truss 5 intervals are arranged in main beam 4 upper ends, be arranged on distance between adjacent two of the steel truss 5 of case beam 8 solid lower ends, both sides and be less than the distance between adjacent two of the steel truss 5 that is arranged on hollow position lower ends in the middle of case beam 8, arranging is like this mainly the quantity in order to reduce steel truss 5, according to case beam 8 stressing conditions reasonable Arrangement steel trusss 5.
On steel truss 5, weld transverse distribution beam 6, transverse distribution beam 6 even interval on the inclined-plane, upper end of many steel trusss 5 is arranged, the upper end connecting bottom board template 7 of transverse distribution beam 6, then at base plate template upper outlet beam 8.The Main Function of transverse distribution beam 6 is situation in strip hand on steel truss 5 to be changed into netted stressed, has increased hand the inside long-pending, makes structure more complete solid.
When assembling, built-in fitting 2 is installed on pillar 1, by being connected shelf bracket 3 be fixed on pillar 1 with built-in fitting 2, at the horizontal upper end face welding main beam 4 of shelf bracket 3, the steel truss 5 of the many vertical main beams 4 of upper end welding of main beam 4, connects transverse distribution beam 6 on the inclination upper surface of many steel trusss 5 again, the even interval of transverse distribution beam 6 is arranged on the inclined plane of steel truss 5, again at transverse distribution beam 6 upper end welding base plate templates 7, both sides scaffolding 9, pouring box beam 8.
The utility model has the advantages that: by adopting steel truss to replace the longeron of shaped steel as support, the task of angular adjustment is transferred to steel truss from shelf bracket, steel truss is light and be convenient to back court machine-shaping, can well ensure construction precision, reduce error.
