Among the figure, 1-steel pipe, 2-flitch, 3-steel plate, 4-penetrates the hole to tight screw rod, 5-veneer, 6-chevron card, 7-hook plate screw rod, the 8-band iron, the 9-screw, 10-is to tight screw rod, the 11-sleeve pipe, 12-steel plate, the spacing concrete of 13-, 14-supports flitch, 15-wedge shape batten, 16-studdle, 17-Concrete In Structures, 18-had before been poured into a mould shear wall, the 19-nut.
The specific embodiment
Fig. 1 is a kind of deformation joint prefab form, by consisting of as veneer 5, flitch 2, the steel pipe 1 of meeting the concrete panel.
Flitch 2 is along vertical distribution of prefab form, and along the back side that laterally is fixed on veneer 5 of prefab form, flitch is fixed on the back side of veneer with tapping screw 9.
Steel pipe 1 is along the cross direction profiles of prefab form, along the outside that vertically is pressed in flitch 2 of prefab form.
One end of hook plate screw rod 7 is welded with band iron 8, and band iron is met the concrete surface edge and is polished into the slope and guarantees that edge fundamental sum veneer is concordant.Pass successively veneer 5, steel pipe 1, flitch 2 with hook plate screw rod 7, the other end is fixing with chevron card 5, becomes an integral prefabricated template.Reserve on the veneer tight screw rod is penetrated hole 4, be welded with in the relevant position, back of steel pipe 1 for the steel plate 3 that connects tight screw rod, be welded with nut on the steel plate 3.Be screwed into nut in order to tight screw rod penetrated.
Fig. 2 is the mounting structure of deformation slit formwork, is made of inner side template, outboard template, studdle 16, support flitch 14 and wedge shape batten 15.
Use first the following wall connecting of the previous cast shear wall 18 in studdle 16 and substructure concrete 17 and the deformation joint outside.To support again 14 of flitches and on studdle 16, place the lower end of deformation joint inner side template, in order to support inner side template.Then make its lower end that abuts against inner side template loosening with pushing against the support flitch in the wedge shape batten 15 insertion deformation joints.
The outside template be placed directly in the substructure concrete above.
Above-mentioned inner side template is the prefab form of the present embodiment, and outboard template can prefab form, also can directly use steel form.
When template is installed, with tight screw rod 10 is welded into integral body with nut 19, the nut that calculates and reserve welding on the steel plate 3 that need to pass steel pipe 1 exposes outside the screw rod 10 of 30-50mm length and stretches out mountain type card 6 and the length of nut welding, and is suitable with the thickness that guarantees interior outboard template spacing and fluid concrete.With what screw rod 10 passed reservation tight screw rod is penetrated hole 4, pierce into again sleeve pipe 11, the other end be screwed into the relevant position, back that is welded in steel pipe 1 be used for connecting in tight screw rod and nut Plate Welding, hold out against with mountain type card fully by constantly tightening screw rod 10 until with nut 19 and to twist motionlessly, screw rod just links together the prefab form of inside and outside both sides tightly at this moment.Sleeve pipe 11 usefulness soft pvcs are made, and install at a certain distance concrete prefabricated that controls shear wall thickness.Stretch out from the back side of veneer 5 at the two ends of sleeve pipe, can enter in the sleeve pipe by mortar leakage prevention.
Construction point:
1) processing of prefab form transverse joint: lay when meeting the concrete panel and abdicate tongue and groove on one side way is middle rib keel between deformation joint, another side is done outlet.Its objective is can have the reliable spreading of horizontal direction prefab form, and efficiency control concrete spillage, guarantees concrete construction quality.
2) preparation method of prefab form: use first the 150mm long bolt, one section is welded with 40 * 3 steel disc and makes the hook plate screw rod, with the hook plate screw rod panel and flitch keel and Φ 4.8 * 3.0 steel pipe connectings are connected into an integral forming template, steel tube framework horizontal spacing@400 ~ 600mm, flitch keel spacing 150mm, and make formwork edge joint compacting under the steel tube framework coverage, guarantee that piece is smooth, tight; With the 3.5x25 self-tapping screw panel and flitch are fixed by 300 spacings.Said method makes and forms an integral body between template and the steel tube framework, and its purpose satisfies integral rigidity and the turnover utilization rate of template.
3) prevent that cement paste from entering screw rod sleeve pipe and control wall thickness problem: way is the wall bushing termination directly to be stretched out meet the concrete panel, makes to water a small amount of spillage that produces in the concrete process and can not enter in the sleeve pipe.
Because sleeve pipe has passed the plate face and has not possessed the wall thickness position-limiting action, thus add the limited support made from fine-stone concrete, to reach the thickness of control shear wall.Its objective is that to guarantee this shear wall through walls to tight screw rod, must reach 100% can extract from wall bushing.
Bottom support when 4) template is installed: way is to utilize lower floor to finish the prepared screw-bolt hole of metope, stretch out screw rod, tighten with nut at the screw rod two ends, adopts and place the way temporary supporting deformation slit formwork of flitch levelling thereon, proofreaies and correct and reinforce so that the workman conveniently carries out template.Do not move down when controlling the typing large form and install with this and when building concrete.
5) template is suitable for reading fixes (not marking among the figure) with jig: way is the jig that utilizes channel-section steel waste material and thick screw rod to form, the channel-section steel section is worn at a welding of the thick screw rod of jig No. 10 channel-section steels, middle parts No. 10, channel-section steel section two sides is symmetrically welded with the big nut supporting with thick screw rod, and the thick screw rod other end leaves the through hole with the diameter 30mm that runs through of spiro rod length perpendicular direction.After the prefab form installation in position is proofreaied and correct, jig snapped in construct between the shear wall finished and the new prefab form of installing, the front end channel-section steel withstands on the two steel pipes of level of prefab form, the middle part channel-section steel is stuck in the shear wall outside of having built, thick bolt tightened to the prefab form direction can guarantee that prefab form is not shifted 1 meter of jig spacing when the concreting.
6) enter in the sleeve pipe for mortar leakage prevention: the screw rod wall bushing is selected the flexible PVC material, makes template certain level be arranged to amount of movement when loosening, does not produce excessive resistance in the lifting process when form removable.Reserve the hole of a high 150mm of wide 100mm in the large mould of every segmentation bottom, be used for stretching into the steel sled when when promoting, running into resistance and assist.Guarantee that tower crane can not run into not clear overload phenomenon in promoting large mold process.
7) form removable: behind concrete initial set (according to taking the time flexibly season, generally be that the non-caked template of concrete gets final product), screw rod 10 is oppositely back-outed from the nut of welding, loosening timber wedge, utilize crowbar that template is loosening, the top jig of dismantling, tower crane hangs out prefab form in deformation joint.
Above-described the utility model embodiment does not consist of the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
