Abstract
Provided is a leakproof energy-saving pull rod for a concrete formwork. A concrete pull rod is welded on a threaded sleeve, a screw rod is matched with the threaded sleeve, and a pulp check base plate and a nut are arranged on the screw rod in a sleeved mode. A screw rod rotator is arranged at one end of the screw rod. The leakproof energy-saving pull rod solves the problem that after the concrete pull rod is rusted, a water leaking channel is easily formed, and the screw rod can be repeatedly used, cost can be effectively lowered, steel can be saved, and concrete quality can be improved.
Description
Technical field
The utility model relates to concrete construction field, is specifically related to a kind of concrete blinding leakage-proof energy-saving pull bar.
Background technology
Development along with the Chinese large-sized concrete construction, the concrete blinding pull bar uses more and more, the concrete pull bar is monolithic at present, after form removal, using welding gun will expose the concrete pull bar cuts off, personnel labor intensity is large, concrete surface intensity is inhomogeneous, and being easy to form leak paths after the pull bar corrosion is a potential safety hazard, can not be suitable for the large-scale water-drawing channel concrete construction of modernization requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of concrete blinding leakage-proof energy-saving pull bar, this Tiebar structure simple, easy to operate can be safely, economical, efficiently carry out the in place of concrete blinding.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of concrete blinding leakage-proof energy-saving pull bar, and the concrete pull bar is welded on screw shell, and screw rod matches with screw shell, is set with grouting backing plate and nut on screw rod.
One end of described screw rod is provided with the screw rod circulator.
Described screw rod main body section is full circle, the special-shaped section of an end termination for consisting of two straightways and two camber lines.
The concrete blinding leakage-proof energy-saving pull bar that the utility model provides, the concrete pull bar is welded on screw shell, and during use, the rotation of screw rod round nose is screwed into screw shell, the backing plate installed additional and nut associating power, opposing concrete lateral pressure; Screw rod main body section is full circle, and an end termination is set to special-shaped half circle cross section, can conveniently take out out screw rod; The invention solves concrete pull bar use procedure in existing large-scale delivery water project, concrete surface exposes pull bar, and to remove labour intensity large, and efficiency is not high, and very easily forms leak paths after the reinforcing pull rod corrosion, and concrete surface intensity is inhomogeneous; There is design principle clear, simple in structure, be easy to make, the advantage such as easy to operate, cost, can obviously improve quality and the application life of concrete surface, realize large-scale delivery water project concrete construction quick, efficient, high-quality, solved after the concrete pulling puccinia graminis loses the problem that is easy to form leak paths and screw rod recycling.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is concrete pull bar elevation of the present utility model.
Fig. 2 is concrete pull bar button-head figure of the present utility model.
Fig. 3 is concrete pull bar special end head figure of the present utility model.
The specific embodiment
Structure of the present utility model as shown in Figure 1, a kind of concrete blinding leakage-proof energy-saving pull bar, concrete pull bar 1 is welded on screw shell 2, screw rod 3 matches with screw shell 2, is set with grouting backing plate 4 and nut 5 on screw rod 3.
As Figure 2-3, an end of screw rod 3 is provided with screw rod circulator 6, and screw rod 3 main body sections are full circle, the special-shaped section of an end termination for consisting of two straightways and two camber lines, i.e. special-shaped half nose circle.
When the utility model is used, screw rod 3 round noses are turned clockwise and are screwed into screw shell 2 with screw rod circulator 6, the other end is installed grouting backing plate 4 and nut 5 with adjusting fixed form position successively through the pattern hole of concrete blinding 7; Screw rod circulator 6 is inserted in to special-shaped half nose circle of screw rod 3 before form removal, is rotated counterclockwise screw rod 3 concrete blinding 7 of back-outing; Form the concrete hole and use same label slightly expanded concrete filling to get final product, backing plate 4 and nut 5 coactions, opposing concrete lateral pressure.
