Description
Technical field
The utility model relates to construction formwork securing member, is specifically related to fastening bolt through walls.
Background technology
At present, the fast development of domestic construction industry, large-scale high-rise cast-in-place shear wall building increases, in shear wall construction, retrain traditional form of construction work to construction formwork is adopt Screw arbor with nut at both-ends, the screw rod of this structure exists: intensity is low, yielding, life cycle is short, quantity consumed is huge, and need arrange service sleeve.Service sleeve also must be rejected in construction in later period from concrete wall, thus greatly constrains the raising of quality in shear wall construction and work efficiency.
Summary of the invention
The utility model for overcoming above-mentioned defect, provide a kind of need not pre-buried, the fastening bolt through walls of being convenient to reclaim, adapt to different-thickness wall construction.
The utility model by the following technical solutions, fastening bolt through walls, comprises the connecting portion of the truncated cone-shaped being positioned at medium position, and the front and back of described connecting portion are respectively equipped with front screw and rear screw rod, rear screw rod is flexibly connected with connecting portion, front screw and rear screw rod is all established and is flexibly connected fastening claw.
Use to not affect screw thread after knocking, the front end of described front screw is provided with threadless boss.
The utility model usefulness is, structure is simple, and the tapering of connecting portion can ensure to take out easily after construction completes, and the rear screw rod of flexible connection can make adjustable range, simplifies step, reduces costs.
