Abstract
The utility model provides a self-supporting device for a steel reinforced concrete composite girder, which solves the problems that steel reinforced concrete composite girder template systems mainly adopt floor-type mat scaffolds and the like for supporting, and the supporting device uses a large amount of steel materials, needs installation and disassembly, consumes a large quantity of labor, and has low construction efficiency and high potential safety hazard. The utility model has the technical scheme that a fixed screw nut is welded on a lower flange slab of the steel reinforced concrete composite girder; the inner end of a load bearing screw rod is screwed into a fixed screw nut; a movable screw nut is screwed into the outer end of the load bearing screw rod; a gasket, a transversal keel, a longitudinal keel and a girder bottom template are orderly arranged on the movable screw nut; and a pair of pulling screw bolts respectively pass through a side girder template and the keels to be welded on a bonding rib. The utility model has the advantages that the cost for the floor-type mat scaffolds is saved, the installation and disassembly cost is saved, and the construction efficiency is improved.
Description
Technical field
The utility model relates to the device of brace summer template system in the reinforced concrete composite structure.
Background technology
At present, the bracing or strutting arrangement of reinforced concrete composite structure beam forms system mainly by the full hall of a console mode scaffold, U-shaped is adjustable shores, form surfacing, keel and split bolt etc. are formed, its beam bottom board plate is shored and born the top working load by the full hall of a console mode scaffold, and give lower floor's beam slab Load Transfer.General direct-current electric welding common steel tube or the bowl fastening type steel pipe that meets the national regulation requirement that adopt of steel pipe adopts the fastener that meets the national regulation requirement, made by malleable cast iron to connect between the steel pipe; Steel pipe top adopts adjustable the shoring with the beam bottom board plate of U-shaped to hold out against; Side template also must be reinforced, and the split bolt that special-purpose subsidiary PVC sleeve pipe is set separately sockets the template of beam both sides and must be on the section steel beam web perforate so that split bolt passes through.This bracing or strutting arrangement must drop into that a large amount of steel pipe, fastener, U-shaped are adjustable to be shored and material such as special-purpose split bolt, install and the time construction of stripping system is loaded down with trivial details, bracing or strutting arrangement is complicated, potential safety hazard is big, consume a large amount of manually and efficiency of construction is lower, time-consuming takes a lot of work, and the recycling rate of waterused of above-mentioned different materials is low, and labor and materials expend seriously; If the sectional dimension of beam is big, when lower floor's beam slab can't bear upper strata beam working load, must install two-layer even the multilayer template system, then expense is bigger.
Summary of the invention
For overcoming the deficiency of prior art, the purpose of this utility model is to provide a kind of reinforced concrete composite structure beam self-supporting device.
The purpose of this utility model is achieved in that it has section steel beam, (at the bottom of the beam and beam side) template, tension rib, horizontal and vertical keel, it is characterized in that: nut is decided in welding on section steel beam bottom wing listrium, the inner end of load-bearing screw rod is screwed into decides nut, moving nut cooperates with the outer end of load-bearing screw rod, is pad, horizontal, vertical keel and beam bottom board plate successively on the moving nut; A pair of split bolt passes from side template and keel respectively, is welded on the tension rib.When at template and section steel beam fluid concrete, its working load passes to section steel beam by beam bottom horizontal keel and load-bearing screw rod, section steel beam reaches lower floor's post wall of having constructed and having finished with the above-mentioned Load Transfer that is afforded again to steel column, this moment, the lower floor beam slab need not bear above-mentioned working load, thereby need not traditional console mode full hall scaffold and U-shaped is adjustable shores.Concrete side load in the beam side is born by split bolt and tension rib, prevents that side template and keel from tilting.
Compared with prior art, the beneficial effects of the utility model are: need not to install console mode full hall scaffold and annex thereof, the expense of not only having saved this equipment has also been saved installation, demolition cost, has also improved efficiency of construction, therefore greatly reduces construction cost; Also eliminated potential safety hazard simultaneously.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a B portion enlarged drawing among Fig. 1.
Fig. 4 is a C portion enlarged drawing among Fig. 1.

The specific embodiment
Referring to Fig. 1, it has section steel beam 1, (at the bottom of the beam and beam side) template 2, tension rib 5, lateral keel 7 and vertical keel 6, referring to Figure 4 and 5, nut 10 is decided in welding on section steel beam bottom wing listrium 3, the inner end of load-bearing screw rod 4 is screwed into decides nut, moving nut 11 cooperates with the outer end of load-bearing screw rod, is minipad 12, big pad 13, horizontal, vertical keel and beam bottom board plate 2 successively on the moving nut; Referring to Fig. 1,3, a pair of split bolt 9 passes from side template and keel respectively, is welded on the tension rib 5.When at template and section steel beam fluid concrete, its working load passes to section steel beam by beam bottom horizontal keel and load-bearing screw rod, lower floor's post wall that section steel beam is given the above-mentioned Load Transfer that is afforded steel column 8 (referring to Fig. 2) and constructed and finished again, this moment, the lower floor beam slab need not bear above-mentioned working load, thereby need not traditional console mode full hall scaffold and U-shaped is adjustable shores.Concrete side load in the beam side is born by split bolt and tension rib, prevents that side template and keel from tilting.
