Abstract
The utility model provides a kind of cantilever steel girder structure through walls, it includes draw ring, angle steel, dowel, steel tenon, wherein, draw ring becomes U-shaped by bending reinforcement, its U-shaped top is provided with screw thread, be embedded in floorslab concrete, with the module contact of floor slab bottoms bottom draw ring after the sidewall suit pvc pipe of draw ring both sides; I iron chooses body of wall after the sidewall of draw ring both sides; Pad bottom i iron and between floor and steel tenon is housed, between i iron both sides sidewall and draw ring both sides inwall, intercalation has dowel; I iron top is provided with angle steel, and angle steel is pressed on i iron top, and its two ends are cut with scissors on the screw thread of draw ring both sides top side wall by bolt.Consumptive material is changed into all materials that can be recycled by this programme, both meets code requirement, meets again " amphitypy society " needs.Experimental result shows, it is respond well, has saved project cost, ensure that workmanship, construction safety is reliable in construction.
Description
Technical field
The utility model relates to technical field of buildings, refers in particular to a kind of cantilever steel girder structure through walls.
Background technology
Along with building operations fastener type steel pipe scaffold technical specification of security JGJ130-2011 standard was the issue of on 01 28th, 2011, implement on December 1st, 2011.Through the transitional period of 1 year, there is further code requirement to substantial risk item suspension scaffold specification nearly.Wherein, for builder's jack i iron draw ring, its shaped steel encorbelment fixed end should adopt 2 (to) and above U-shaped steel draw ring or anchor bolt and building structure beam slab fix, U-shaped reinforcing bar draw ring or anchor bolt should be pre-buried to concrete beam backplane level reinforcement location, and should weld with concrete beam and board bottom layer of the reinforcing steel or colligation firm, its anchorage length should meet the regulation of Bar Anchorage in existing national standards " Code for design of concrete structures " GB50010.It is the reinforcing bar of 18mmHRB335 that anchoring ring arranges two long diameters of 1.5m, as beam slab place be provided with >=18mm reinforcing bar time can not add in addition.Existing way is after cantilever steel girder completes, and is directly to be cut by U-shaped reinforcing bar, so causes waste of material, and then adds construction cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cantilever steel girder of reusable edible structure through walls.
For achieving the above object, technical scheme provided by the utility model is: a kind of cantilever steel girder structure through walls, it includes draw ring, angle steel, dowel, steel tenon, wherein, draw ring becomes U-shaped by bending reinforcement, its U-shaped top is provided with screw thread, is embedded in floorslab concrete, with the module contact of floor slab bottoms bottom draw ring after draw ring both sides sidewall suit pvc pipe; I iron chooses body of wall after the sidewall of draw ring both sides; Pad bottom i iron and between floor and steel tenon is housed, between i iron both sides sidewall and draw ring both sides inwall, intercalation has dowel; I iron top is provided with angle steel, and angle steel is pressed on i iron top, and its two ends are cut with scissors on the screw thread of draw ring both sides top side wall by bolt.
Be coated with adhesive tape or engineering films bottom described draw ring, the diameter of pvc pipe is greater than the diameter of draw ring both sides reinforcing bar.
Consumptive material is changed into all materials that can be recycled by this programme, both meets code requirement, meets again " amphitypy society " needs.Experimental result shows, it is respond well, has saved project cost, ensure that workmanship, construction safety is reliable in construction.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, cantilever steel girder described in the present embodiment structure through walls, it is characterized in that: it includes draw ring 1, angle steel 2, dowel 4, steel tenon 5, wherein, draw ring 1 becomes U-shaped by bending reinforcement, its U-shaped top is provided with screw thread, be embedded in floor 6 concrete after the sidewall suit pvc pipe 7 of draw ring 1 both sides, be coated with adhesive tape or engineering films bottom draw ring 1, the diameter of pvc pipe 7 is greater than the diameter of draw ring 1 both sides reinforcing bar.Bottom draw ring 1 with floor 6 bottom module contact; I iron 3 chooses body of wall after the sidewall of draw ring 1 both sides; Pad bottom i iron 3 and between floor 6 and steel tenon 5 is housed, between i iron 3 both sides sidewall and draw ring 1 both sides inwall, intercalation has dowel 4; I iron 3 top is provided with angle steel 2, and angle steel 2 is pressed on i iron 3 top, and its two ends are cut with scissors on the screw thread of draw ring 1 both sides top side wall by bolt.The manufacturing process of the U-shaped ring of the present embodiment can be processed separately, by the impact of time, place and weather.Overlap the pvc pipe to a large diameter gradation at U-shaped vertical burr in a pre-installation, wrap bottom U-shaped draw ring with adhesive tape.After using, in demolishing process, do not affect concrete structure, it is convenient to remove, all recyclable recycling of its building block.Draw ring, after dismounting, will leave hole in floor.PVC residue and loosening concrete in wall need be cleared up in shutoff hole, and then with the microdilatancy pea gravel concreten higher than a former concrete label, first shutoff bottom 1/3, top 2/3 is in disposable shutoff.This programme is applied widely, and industry is all applicable with the draw ring of the builder's jack of civilian construction and overhanging unloading platform.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
