The put more energy into design feature of steel purlin lower node jig of the utility model is: watering on the beam section along beam section direction anchoring outrigger to be poured, vertical adjuster, laterally adjuster and vertical adjuster are set respectively on described outrigger, utilize described vertical adjuster, laterally adjuster and vertical adjuster adjustment are suspended on the vertical and horizontal level of the steel purlin lower node on outrigger.
The put more energy into design feature of steel purlin lower node jig of the utility model also is: a pair of parallel outrigger along beam section direction to be poured setting waters on the beam section by pressing beam shaped steel and anchor rib to be anchored at, two ends longitudinal spacing shaped steel is set respectively between described pair of parallel outrigger, and the form with cross-arm on described pair of parallel outrigger arranges respectively two ends vertical spacing shaped steel; Weld respectively vertical accurate adjustment bolt on four vertical corners of steel purlin gusset plate, with vertical accurate adjustment bolt, described gusset plate is suspended on vertical spacing shaped steel; Horizontal accurate adjustment bolt is set on described outrigger, is butted on the side plate of steel purlin lower node with the front end of described horizontal accurate adjustment bolt; Vertical accurate adjustment bolt is set on described longitudinal spacing shaped steel, be butted on the side plate longitudinal terminal surface of steel purlin lower node with the front end of described vertical accurate adjustment bolt, described vertical adjuster is to be made of longitudinal spacing shaped steel and vertical accurate adjustment bolt, described horizontal adjuster is horizontal accurate adjustment bolt, and described vertical adjuster is to be made of vertical spacing shaped steel and vertical accurate adjustment bolt.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model be the beam section of having completed construction be the basis, jig is set, make the steel purlin lower node of putting more energy on without fixed platform accurately be located.
2, precise adjusting device features simple structure in the utility model, on-the-spot easily processing and fabricating plays good economic effect.
3, in the utility model, jig itself is adjuster and a fixed system, has broken away from not fixed environment of platform hanging basket.

Fig. 1 is rough package drawing in the utility model;
Fig. 2 is adjuster floor map in the utility model;
Fig. 3 is adjuster longitudinal section schematic diagram in the utility model;
Number in the figure: 1 outrigger; 2 vertical accurate adjustment bolts; 3 horizontal accurate adjustment bolts; 4 vertical accurate adjustment bolts; 5 press beam shaped steel; 6 anchor ribs; 7 vertical spacing shaped steel; 8 longitudinal spacing shaped steel; 10 steel purlin lower nodes; 11 have watered beam section, 12 beam sections to be poured.
The specific embodiment
Referring to Fig. 1, the steel purlin lower node jig of putting more energy in the present embodiment is at the direction anchoring outrigger 1 that waters on beam section 12 along beam section 11 to be poured, vertical adjuster, laterally adjuster and vertical adjuster are set respectively on outrigger 1, utilize vertical adjuster, laterally adjuster and vertical adjuster adjustment are suspended on the vertical and horizontal level of the steel purlin lower node 11 on outrigger 1.
In concrete enforcement, as Fig. 1, Fig. 2 and shown in Figure 3:
A pair of parallel outrigger 1 along beam section direction to be poured setting waters on beam section 11 by pressing beam shaped steel 5 and anchor rib 6 to be anchored at, two ends longitudinal spacing shaped steel 8 is set respectively between pair of parallel outrigger 1, and the form with cross-arm on pair of parallel outrigger 1 arranges respectively two ends vertical spacing shaped steel 7; Weld respectively vertical accurate adjustment bolt 2 on four vertical corners of steel purlin gusset plate, with vertical accurate adjustment bolt 2, gusset plate is suspended on vertical spacing shaped steel 7; Horizontal accurate adjustment bolt 3 is set on outrigger 1, is butted on the side plate of steel purlin lower node 10 with the front end of horizontal accurate adjustment bolt 3; Vertical accurate adjustment bolt 4 is set on longitudinal spacing shaped steel 8, be butted on the side plate longitudinal terminal surface of steel purlin lower node 10 with the front end of vertical accurate adjustment bolt 4, vertically adjuster is to be made of longitudinal spacing shaped steel 8 and vertical accurate adjustment bolt 4, laterally adjuster is horizontal accurate adjustment bolt 3, and vertical adjuster is to be made of vertical spacing shaped steel 7 and vertical accurate adjustment bolt 2.
In specifically implementing, outrigger 1 adopts the I40b i iron, and vertical accurate adjustment bolt 2, horizontal accurate adjustment bolt 3, vertical accurate adjustment bolt 4 and anchor rib 6 all adopt φ 25 fining twisted steels; Press beam shaped steel 5, vertical spacing shaped steel 7 and longitudinal spacing shaped steel 8 to be I14 i iron Two bors d's oeuveres;
