Embodiment one:
Whole manufacturing process of watering formula mainly comprises following content:
1, the making of steel support
Behind four stiffening rib 2 cutting stocks to steel plate supportive body 1 and two ends, supporting steel plate will dig limit processing, then welds, and forms steel plate and supports; With the rust cleaning of steel plate stayed surface, paste high-elastic offset plate, foam rubber and non-cohesive material.
2, profiled sheet cuts and splices
According to the setting party of two closed-section steel deck 3 ribs of slab to, two closed-section steel decks 3 are carried out cutting stock, article two, the splicing between the profiled sheet can at the rib of slab overlapping of two profiled sheets, connect by pulling rivet or tapping screw on rib of slab.
The rib of slab direction of two closed-section steel decks 3 both can arrange with the axis direction of steel plate supportive body 1 is consistent, also can along continuous straight runs or vertical direction setting; When rib of slab direction along continuous straight runs or vertical direction, for improving the anti-bending bearing capacity of profiled sheet, need near the slit of remaining silent of two closed-section steel decks 3 supporting be welded.
3, the making of perforate channel-section steel, segment square tube, segment channel-section steel, steel end plate and short channel-section steel etc.
Segment square tube 11, the 3rd channel-section steel 12, steel plate 8 and the second channel-section steel 6 are cut making, when the parallel back shaft of profiled sheet rib of slab to the time, make the perforate channel-section steel by Fig. 5～Figure 10; If profiled sheet rib of slab level to or when vertically putting, make the perforate channel-section steel by Figure 11 and Figure 12 respectively.
4, steel plate is supported on the location in the perforate channel-section steel, the welding of bottom steel end plate; Then profiled sheet, perforate channel-section steel, steel plate support and be connected channel-section steel etc. in place be connected
Segment square tube 11 and the 3rd channel-section steel 12 can be by self-drilling connections (such as Fig. 5～shown in Figure 7) on perforate channel-section steel 5; When profiled sheet rib of slab level to or when vertically putting, with segment square tube 11 by self-drilling connection on the first channel-section steel 5; Make the tapping screw head of a nail as far as possible and perforate channel-section steel edge of a wing external surface flush, this is conducive to follow-up profiled sheet and perforate channel-section steel are adjacent to installation; Then in the wallboard lower end steel plate 8 and the first channel-section steel 5 are welded (such as Fig. 8, shown in Figure 9).
After above-mentioned finishing, will lack channel-section steel 6 by tapping screw and be connected on the side pressure shape steel plate.Then, Double-layer profiled steel sheet is put in above-mentioned perforate channel-section steel, steel support etc.After in place, utilize tapping screw, Double-layer profiled steel sheet is connected (Fig. 1～Fig. 4, Figure 11, Figure 12) with the perforate channel-section steel, and with the profiled sheet of opposite side be connected channel-section steel and connect.
5, at Double-layer profiled steel sheet 3 interior concretings 4, and behind solidifying 4 knots of concrete, welding upper steel end plate 8
Above-mentioned profiled sheet with steel support be connected the steel member in place be connected complete after (during actual fabrication, can be connected by the scaffold of outer setting the steel member that above-mentioned connection is complete firmly in place with flitch), concreting in Double-layer profiled steel sheet, and vibration compacting.
For ease of concreting, in the making, weld first bottom steel end plate (Fig. 8), behind the concrete coagulation to be cast, weld again the upper steel end plate.For avoiding leaving the hole between concrete that wallboard upper end condensed and steel end plate, increase the adhesion stress between steel end plate and R.C. wall board, can on the upper steel end plate, open in advance several apertures, welded the steel end plate after, the high-strength mortar that injects microdilatancy tamps the hole.
Embodiment two:
1, the making of steel support
Behind four stiffening rib 2 cutting stocks to steel plate supportive body 1 and two ends, supporting steel plate will dig limit processing, then welds, and forms steel plate and supports.
2, just, two making with the assembled wall board of bolt hole and groove in the back side
According to the direction of profiled sheet rib of slab, profiled sheet is carried out cutting stock.Article two, the splicing between the profiled sheet can at the rib of slab overlapping of two profiled sheets, connect by pulling rivet or tapping screw on rib of slab.
Cut and be spliced into after the profiled sheet, in profiled sheet periphery high-strength bolt junction, the slit of remaining silent of the profiled sheet of will remaining silent welds, thereby after peripheral bolt was connected, double-deck assembled wall board is cooperative bearing better.Then, bonding plastics pipe on profiled sheet (indwelling bolt hole) arranges the larger straight wood lath of rigidity or steel plate bar (keep somewhere wallboard on groove), and on profiled sheet concreting.The rib of slab direction of profiled sheet both can parallel back shaft to (Figure 13), also can along continuous straight runs (seeing Figure 21) or vertical direction (seeing Figure 22).When rib of slab direction along continuous straight runs or vertical direction, for improving the anti-bending bearing capacity of profiled sheet, the slit of remaining silent that supports near profiled sheet is welded (Figure 21 and Figure 22).
3, steel plate just be supported on, in place in the two wallboard grooves in the back side, by high-strength bolt two wallboards are assembled
After supporting and wallboard with holes all make, with the steel plate support just placing, the two wallboard grooves in the back side, in place after, by high-strength bolt two wallboards are assembled (Figure 13, Figure 21 and Figure 22).
Operating principle:
The built-in support without stick steel plate of closed-section steel deck of the present invention-Combined concrete wallboard is to support with the steel of outside assembled wall board as confining part, is installed in the steel frame by steel plate of the present invention is supported, and can form steel braced frame structure; Because being subjected to the constraint of outside wallboard, support under the tension and compression effect and all can surrender, can improve the anti-seismic performance of the steel braced frame structure that adopts the clean steel support, the floor shearing that is applied in the support is born with the form of axially loaded alone by the steel plate support basically, wallboard only is used to built-in steel plate to support lateral restraint is provided, prevent that steel plate from supporting significantly whole and part unstability of pressurized, wallboard is not shared the axle power of support substantially.When wallboard lateral restraint ability was enough, wallboard was in elasticity, and steel plate supports can be in elasticity, namely supported not axially surrender, also can significantly develop plasticity, and namely back shaft is to surrender; Wallboard can doublely be done the partition wall of building.
