Abstract
The utility model relates to a concrete blinding opposite-pulling combo assembly which comprises a connecting rod with the screw thread at both ends, two nuts which can be rotationally connected with two ends of the connecting rod and a fastener which can be rotationally connected to the nuts; wherein the nut is formed by embedding a hexagonal steel jacket with a flange into a cone plastic component; the steel jacket is provided with an inner screw thread through hole, while the hexagonal end of the steel jacket is arranged on the large head end of the cone plastic component so as to provide convenience for locking or loosening ejection operation for starters or wrenches. The utility model has the advantages of that the structure is designed reasonably and the connection for connecting rod, nut and fastener is reliable; the nut with inlaid treatment not only solves the defect of difficult demounting and time and labor saving, but also enhanced the nut recycling utilization rate.
Description
Technical field:
The utility model belongs to building field, and particularly a kind of concrete blinding is used for the securing member that the cast-in-situ concrete shear wall is built template to drawing combination set.
Background technology:
At building field, but shear wall cast-in-place construction longitudinally, the support of template i.e. difficulty comparatively, needs to rise two template multiple spots are related, avoids concrete weight component with the distortion of bottom Form hanger or crack, and influences construction quality or waste material.Construction method is that equilibrium is laid with the plastic casing-pipe that passes for reinforcing bar between two vertical templates at present, or directly reinforcing bar is passed two templates, then with two Template Location.And multiple shear wall formwork securing member was disclosed in the patent gazette, general structure comprise built-in band double end thread connecting rod, can be rotated with through hole nut at the connecting rod two ends, and outside nut, be equipped with securing member.Connecting rod and two nuts are between two templates during use, and two nuts in order to regulate the template spacing, promptly play fixation fastener on the one hand on the other hand, utilize securing member with the related location of template.After the purpose of this scheme is concrete curing, securing member and nut can be separated respectively, reclaim and reuse.But because the nut design is unreasonable, the concrete that usually is cured clings and can't deviate from.
Summary of the invention:
The purpose of this utility model is the defective at prior art, designs a kind of concrete blinding of demoulding recovery that is easy to drawing combination set.
Technical solutions of the utility model are achieved in that a kind of concrete blinding is to drawing combination set, comprise connecting rod, two nuts that can spin with the connecting rod two ends of a double headed roller thread and can be screwed in securing member on the nut, wherein nut forms by inlaying a flanged (FLGD) hexagonal steel bushing in the taper plastic, steel bushing band internal screw thread through hole, steel bushing hexagonal end is convexly set in taper plastic stub end, is convenient to the locking of bottle opener or spanner or unclamps stripping operation.
In addition, plastic also wraps up the steel bushing end face of flange, reduces steel bushing and concrete contact surface as far as possible, effectively avoids steel bushing to cement in concrete, makes the demoulding more smooth.
The utlity model has reasonable in design, being spirally connected of parts such as connecting rod, nut and securing member is reliable, and nut has not only solved the defective that is difficult to the demoulding by damascene process, and saving of work and time also improves the recovery utilization rate of nut; Constructing operation only needs spanner or built-in spanner to get final product, and except that connecting rod, remainder is reusable.Connecting rod all the time with concrete curing together, and submerge within the metope in the connecting rod two ends, directly levelling can cover, and guarantees that the waterproof concrete wall does not seep water.

Fig. 4 nut two sectional drawings
Wherein

22-steel bushing 3-securing member
The specific embodiment:
With reference to Fig. 1 and Fig. 2, concrete blinding is to drawing combination set, comprises connecting rod 1, two nuts 2 of double headed roller thread and can be screwed in securing member 3 on the nut, and securing member 3 provides the effect of locating template.As Fig. 1, securing member 3 studs and a flanged nut counterpart are formed, and can be about to the stud locking during use earlier on nut 2, set up template and lock flanged nut counterpart to get final product.This securing member 3 structures can be fit to the template of different-thickness.
Securing member 3 also can after template installs, be locked securing member 3 and be got final product as the flanged bolt standard component of Fig. 2 except that said structure, and this securing member 3 can only be fit to the template of standard thickness, as if the template thickness difference, promptly need cooperate the bolt fastener of different length.
With reference to Fig. 3 and Fig. 4, nut 2 forms by inlaying a flanged (FLGD) hexagonal steel bushing 22 in the taper plastic 21, and steel bushing 22 band internal screw thread through holes are convenient to connecting rod 1 and securing member 3 is sealed, and steel bushing 22 hexagonal ends are convexly set in taper plastic 21 stub ends, tool operations such as convenient wrench.Nut 2 produced by insert molding during by injection moulding, production efficiency is high and both are in conjunction with firm, be fit to reuse, and steel bushing 22 is a hexagonal structure, not only reduce the possibility of skidding with plastic, and have enough stress surfaces again, bear the rotary manipulation of instrument such as spanner, also get rid of certainly and adopt four jiaos or octagonal steel nested structure.In addition, plastic 21 also wraps up steel bushing 22 end face of flange, can further reduce the possibility that ferrous material contacts with concrete like this, and is conveniently stripped.
Described plastic 21 diameter at butt ends are 30 to 40mm, and top diameter is 20 to 26mm, and length is 15 to 35mm.And plastic 21 big end surface concavity structures, the protruding central fovea in edge in the time of on withstanding on template, forms edge deformation and is close on the template, can reduce cement paste and flow to end face, and increase the difficulty of the demoulding.
