Abstract
The utility model relates to a waterproof opposite-pull screw rod, which comprises a waterproof joint screw nut, wherein the waterproof joint screw nut is provided with two U-shaped screw holes in opposite arrangement, screw rods are respectively connected into the two U-shaped screw holes, and the end parts of the two screw holes are provided with conical protecting sleeve pipes. The waterproof opposite-pull screw rod has the beneficial effects that the integral internal and external waterproof threaded screw nut and the conical protecting sleeve pipes of the screw rods are adopted, the structure is simplified, the screw rods and the protecting sleeve pipes can be repeatedly dismounted and used, a large amount of labor and materials are saved, and the cost is reduced to a great extent.
Description
Technical field
The utility model relate in the building operations set up, the device of support shuttering, especially a kind of waterproof Screw arbor with nut at both-ends.
Background technology
At present, in all kinds of structure cast-in-situ concrete constructions, highrise building particularly in the basement wall body construction, generally uses a kind of centre to be welded with flashing or is with water proof ring and Screw arbor with nut at both-ends that both sides are welded with spacer bars fixes template, spacer bars also must fill up little plank outward, after concrete pouring was intact, screw rod can't take out, and the screw rod that stretches out outside the body of wall makes the bad dismounting of template, also need after the form removal wood particle is drawn out in body of wall, and excision exposes screw rod.So not only cause the waste of great deal of steel, and undercut can appear in the waterproof welding procedure, to leak weldering, rosin joint phenomenon or water proof ring waterproof effect not good, thereby influence stretching resistance in the building operations, the basement wall water resistance is bad, occurs seepage flow after the construction, drainage influences workmanship.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of simple in structure, and tension pressure is big, the waterproof Screw arbor with nut at both-ends of better anti-leakage property, easy installation and removal.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of waterproof Screw arbor with nut at both-ends; it comprises the water joint nut; the water joint nut has two U-shaped screws that are oppositely arranged; be connected with screw rod respectively in described two U-shaped screws, the end of two U-shaped screws is provided with the taper protective casing.
Further, water joint nut and two U-shaped screws that are oppositely arranged are wholely set, and are shaped as Lv.
Further, the taper protective casing is plugged in the end of described U-shaped screw.
Further, the inside of two U-shaped screws be provided with screw rod on the internal thread that is complementary of external screw thread.
The beneficial effects of the utility model are: adopt inside and outside waterproof screw nut of integral type and screw rod taper protective casing, simplify the structure, but screw rod and protective casing repeated removal use, saved a large amount of manpowers, material resources, greatly the reduction of degree cost.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
(Fig. 1 is a cross-sectional schematic of the present utility model) as shown in Figure 1, a kind of waterproof Screw arbor with nut at both-ends comprises water joint nut 2, water joint nut 2 has two U-shaped screws 21 that are oppositely arranged, and is connected with screw rod 1 respectively in two U-shaped screws 21.Be provided with protective casing 3 in the end of described two U-shaped screws.Described protective casing 3 is plugged in the end of described U-shaped screw.
Water joint nut 2 and two U-shaped screws 21 that are oppositely arranged are wholely set, and are shaped as Lv.In use, effectively stop the percolating water phenomenon that fluid concrete construction back occurs, use the detachable back of screw rod and protective casing to reuse because of having adopted one water joint nut.
Taper protective casing 3 has been stopped to occur the spillage phenomenon greatly because of slit, traditional welding location.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
