Description
The invention belongs to the building operations template, be specially adapted to the construction formwork of monolithic reinforced concrete structure deformation joint.
In industry and civilian construction, often because of considering that foundation uneven settlement or shockproof requirements are provided with deformation joint.Deformation joint brings many difficulties to construction, and when particularly the deformation joint both sides were the cast in situ ferroconcrete wall body, difficulty of construction was bigger.Job practices to the monolithic reinforced concrete structure deformation joint has two kinds at present:
Filling with light material method in the deformation joint, the one, the body of wall of construction one side is built gas concrete piece wall by laying bricks or stones after the demoulding earlier, plaster, and then construction opposite side reinforced concrete wall; Or the assembling reinforcement simultaneously of both sides body of wall, the middle benzene plate that inserts, both sides are concrete perfusion simultaneously.This job practices expense of taking a lot of work expects that long in time limit, especially both sides while concrete perfusion guarantees the position of deformation joint is difficult, the more important thing is that the packing material in the deformation joint greatly reduces the anti-seismic performance of building.
Also has the Elastic forming board construction method in addition, Elastic forming board is by two thicker steel plate (δ=12mm) combine, on two steel plates, be welded with the gad piece respectively, the mutual correspondence in its position in groups, utilize the lozenges of every group of gad piece to slide up and down adjustment template thickness size (being the width of deformation joint), utilize the dislocation of wedge to come stripping simultaneously.This job practices exists template from great, one group of nearly 7-10 ton of deformation slit formwork is heavy, therefore, need select high-power crane for use during construction, engineering cost height, and template processing request precision height are assembled, dismantle, transport all cumbersome, need kits such as a cover portal frame, jack, and construction location is not easy to be guaranteed.
The objective of the invention is: invent a kind of large forms for deformation joint that is used for the building structure deformation joint construction,, guarantee the anti-seismic performance of building with the packing material in the cancellation deformation joint, simplify formwork structure simultaneously, alleviate template weight, easy constructing operation reduces engineering cost.
Large forms for deformation joint of the present invention is made up of deformation joint exterior sheathing, inner formword, interior template support, working platform, through-wall bolt.It is characterized in that: the deformation joint exterior sheathing by shaped steel do cross rib, perpendicular rib becomes flat die plate with the steel facing assembly welding, deformation joint exterior sheathing lower end is bearing on the support bar through walls, the deformation joint exterior sheathing is fastening by through-wall bolt and inner formword.
The specific constructive form of deformation joint exterior sheathing is: weld single limb channel-section steel at a certain distance and make cross rib 2 on steel facing 1, do perpendicular rib 3 with two limb channel-section steels again, the steel facing frame is made by angle steel or channel-section steel, makes whole deformation joint exterior sheathing that rigidity preferably be arranged; Along the centre of every group of perpendicular rib of two limbs, uniform three through-wall bolt holes are set from top to bottom, and hold-down nut 4; Welding hanging ring 6 and clamp 5 on the frame of the top of deformation joint exterior sheathing are used to lift and limit the thickness of placing of concrete body of wall; On the frame of deformation joint exterior sheathing both sides, be welded with draw ring 16, be used for mutual drawknot with the sides adjacent template edge.
The bolt that through-wall bolt also can use band to spend slightly can not established nut, and establish a backing plate on perpendicular rib, fastening with voussoir.
The job practices of large forms for deformation joint of the present invention is: after a side wall body demoulding, cleaning out, planar survey is emitted the body of wall line on the substructure of having constructed; On the substructure finished of constructing, put on bolt or round steel in row's bolt hole, form the support bar through walls of large forms for deformation joint; Will the construct body of wall reinforcing bar of a side of colligation is provided with built-in fitting, after latent inspection finishes, and upright inner formword, interior template support, working platform, and the adjustment fixed-site, hang in the deformation joint exterior sheathing then, penetrate through-wall bolt, adjust fastening after, placing of concrete, maintenance reaches removes form removal after the intensity.
Adopt the band through-wall bolt of degree slightly as large forms for deformation joint, need to leave the work hand hole on the relevant position of the side wall body that formerly construct, be used for direct formwork erection and striking job.
The invention has the advantages that: structure of transvers plate is simple, easy processing and fabricating, in light weight, cost is low, does not need special instrument, easy and simple to handle, the saving of labor, save time, laborsaving, each dismounting all is no more than half an hour, but accelerating construction progress, and can save packing material in the deformation joint, satisfy the anti-seismic performance of structure.
