Abstract
The utility model relates to a large-molding-board counter-pull stranded wire, which is mainly characterized by consisting of a large molding board, an anchoring system and a stranded wire, and is characterized in that the stranded wire is pulled in opposite direction to pass through the large molding board, and two ends of the stranded wire are fixed and pulled by the anchoring system. The anchoring system comprises a liner plate, a tension bushing, an anchor cylinder, a squeezing bushing and a clamping piece, wherein the tension bushing is fixed on the liner plate. After the large molding board is installed and positioned, the counter-pull stranded wire on which a jacket is sleeved passes through a counter-pull hole along the large molding board, the anchoring system at one side the large molding firstly passes through one end of the stranded wire to be tightened, and the anchoring system at another side passes through another end, and the stranded wire is pulled and the anchoring system is screwed up. Compared with the prior tie bolt, the stranded wire can reduce the aperture, obviously reduce the repairing quantity and the viewing flaw on the surface of the concrete and can improve the repair working efficiency.
Description
Technical field:
The utility model relates to large form to drawing load bearing system, and particularly a kind of large form is to drawing steel stranded wire.
Technical background:
At present, China enterprise in charge of construction to large forms such as shear wall to drawing mode, mainly adopt split bolt.The shortcoming of this mode is, the diameter of bolt big (28mm or 32mm etc.), after the form removal, the bolt aperture is big, the workload that need fill up is big, and influences the concrete surface impression quality, and body structure surfaces such as wall that the clear-water concrete impression requires, plate, beam are especially arranged, require strictness more, it is bigger that the mode of employing split bolt reaches the requirement difficulty.
Summary of the invention:
The utility model is the deficiency that exists in the above-mentioned technology, provides a kind of large form to drawing steel stranded wire, not only can reduce to fill up workload, and makes body structure surfaces such as wall, plate, beam Paint Gloss, can be more near the impression of clear-water concrete.
The purpose of this utility model is achieved in that described large form is made up of large form, anchor system and steel strand drawing steel stranded wire, and it is characterized in that: to passing large form, the two ends of steel strand are fixed and strained with anchor system to drawing steel stranded wire.Wherein said anchor system comprises backing plate, stretch-draw sleeve, anchor tube, compression sleeve and intermediate plate, and the stretch-draw sleeve is fixed on the backing plate, and the stretch-draw sleeve has internal thread, anchor tube and has external screw thread, compression sleeve band internal thread, intermediate plate are arranged is taper.
When anchor system is installed, installation process is: the both sides that at first backing plate are placed on large form, to over against pulling eye, at the steel strand two ends that install sheath intermediate plate, anchor tube and compression sleeve are installed successively from inside to outside then, backing plate is positioned at the outside of large form, drawing steel stranded wire is passed on the large form to pulling eye and backing plate, install successively from inside to outside at the two ends of steel strand intermediate plate, anchor tube and compression sleeve and the tension.For the ease of removing more easily after finishing, the surface of steel strand scribbles lubrication oil, and the outside is with sheath, dismounting the time, can extract steel strand smoothly out like this, and sheath remains in the template.By steel hinge line two ends anchor system stretch-draw steel strand, make the large form system can effectively bear the lateral pressure that concrete produces in the process of building.The reversed in order of the order of removing large form when installing.By backing plate, tapped stretch-draw sleeve, be with externally threaded anchor tube, tapped compression sleeve, cone-shaped clip, steel strand, plastic sheath etc. to form
Operating principle of the present utility model is, after the large form installing and locating, with put on sheath to drawing steel stranded wire along pulling eye is passed on the large form, earlier the anchor system of large form one side is through an end of steel strand and fastening, then the anchor system of opposite side is through the other end of steel strand, according to the inboard thickness requirement of template, the tension steel strand are also tightened anchor system.During the concrete form removal, earlier anchor system is unclamped, backs out, then steel strand are extracted out and recycling, sheath remains in the concrete, because the hole that is produced is very little, can fill out by hole by grouting mode, and surperficial impression is good.
The present split bolt that adopts, advantage of the present utility model is to simplify technology, accelerates speed of application, improves patch work efficient, reduces labour intensity, can reduce the pulling eye footpath, significantly reduce concrete surface repairing amount and impression defective, construction quality is good, the large form surfacing, form removal early, can improve the inherent quality and the surface quality of walls concrete, reduce wet trade, can reach clear water soil construction reference.

Fig. 2 is the plan view of an example of cone-shaped clip of the present utility model
Fig. 3 is the side view of an example of cone-shaped clip of the present utility model
Fig. 4 is the profile of steel strand of the present utility model
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
By Fig. 1 and Fig. 4 as can be known, earlier with steel strand 8 surperficial coating lubricating oil 9, cover upper jacket 10, then the one end is penetrated successively backing plate 1, stretch-draw sleeve 2, anchor tube 3, intermediate plate 5, compression sleeve 4, tighten anchor tube 3 and compression sleeve 4, intermediate plate 5 is clamped drawing steel stranded wire 6, with its other end penetrate template 7 to pulling eye, repeat said procedure, to the anchor system of drawing steel stranded wire 6 other ends be installed, turn stretch-draw sleeve 2, make drawing steel stranded wire is tightened, the lateral pressure that template system is produced when bearing concreting.During form removable, earlier anchor system is unclamped, backs out, then steel strand are extracted out and recycling, sheath remains in the concrete.
Fig. 2 and Fig. 3 are the plan view and the side view of a preferred embodiment of cone-shaped clip.
