Abstract
The utility model discloses a waterproof opposite-pull screw rod of a wall body. The waterproof opposite-pull screw rod disclosed by the utility model is composed of two screw rods (7) with threads at two ends and a screw rod butt-joint piece (1). The waterproof opposite-pull screw rod is characterized in that the screw rod butt-joint piece (1) is a short rod body with thread blind holes at two ends or a short thread pipe provided with a water-separating baffle (8); the length of the short rod body or the short thread pipe is less than the thickness of the wall body; and the screw rod butt-joint piece (1) is provided with a waterproof sheet (2). Compared with the prior art, the waterproof opposite-pull screw rod has the advantages that after use, one part remained in the wall body is shorter, so that the material is saved and the construction cost is reduced. Furthermore, after the waterproof opposite-pull screw rod is used, one part remained in the wall body is shorter; and compared with the prior art, the waterproof opposite-pull screw rod has the advantages that the diameters of the screw rod and the screw rod butt-joint piece are enlarged, the tensile strength is improved, the reworking rate is low and the engineering schedule is fast.
Description
Technical field
The utility model relates to a kind of screw rod through walls, and especially a kind of screw rod is not stayed the split type body of wall waterproof Screw arbor with nut at both-ends in the body of wall.
Background technology
The patent No. is the Chinese utility model patent of ZL200820028937.X, discloses a kind of body of wall waterproof Screw arbor with nut at both-ends.This body of wall waterproof Screw arbor with nut at both-ends is made up of with the pull bar that is connected with the supporting sleeve two ends the supporting sleeve of centre, and this body of wall waterproof Screw arbor with nut at both-ends supporting sleeve after use is stayed in the body of wall, and the length of supporting sleeve is the thickness of body of wall.The patent No. is the Chinese utility model patent of ZL200920088770.0; A kind of split type split bolt is disclosed; By the middle part have the body of rod of sealing pad, the adapter sleeve at body of rod two ends constitutes with the tie-strut that two ends are connected with adapter sleeve; This split type split bolt adapter sleeve at its body of rod and two ends after use is stayed in the body of wall, and the length of the body of rod adds the length of the adapter sleeve at two ends, equals the thickness of body of wall.Stay inside cavity after the drawback of above-mentioned body of wall waterproof Screw arbor with nut at both-ends and split type split bolt is to use and divide longly, waste material increases construction cost; In addition, the supporting sleeve of body of wall waterproof Screw arbor with nut at both-ends is a thread-rolling screw, and bonding strength is low, causes easily, right inefficacy, and rework rate is higher, influences construction speed; Split type split bolt is partly longer owing to staying in the body of wall, and businessman is for reducing cost, and the diameter of staying the shank portion in the body of wall is generally less; Tensile strength is low, often occurs the phenomenon that the body of rod is broken in the work progress, therefore; Rework rate is also higher, influences construction speed.Therefore, staying the short body of wall waterproof Screw arbor with nut at both-ends of part in the body of wall after designing a kind of use, is the present technical issues that need to address.
Summary of the invention
The utility model technical problem to be solved is stayed the short body of wall waterproof Screw arbor with nut at both-ends of part in the body of wall after providing a kind of the use.
The technical scheme that the utility model solves its technical problem is:
Body of wall waterproof Screw arbor with nut at both-ends; Form by two screwed screw rods in two ends and screw rod interfacing part; Described screw rod interfacing part is that quarter butt body or the centre that two ends are threaded blind hole is provided with water proof closure plate short thread pipe; The length of quarter butt body or short thread pipe is provided with flashing much smaller than the thickness of body of wall on the screw rod interfacing part.
Compared with prior art, the utility model is partly shorter owing to staying after using in the body of wall, and economical with materials reduces construction cost.In addition, because it is shorter to stay the interior part of body of wall after using, compared with prior art, can also the enlarged diameter of screw rod and screw rod interfacing part be improved tensile strength, rework rate is low, and programming is fast.
The utility model preferably technical scheme is; Both sides outer cover at the flashing of screw rod interfacing part is equipped with the screw rod protective casing; Flashing is close in the inner of screw rod protective casing, is set with positive stop in the outer end of screw rod protective casing, the inner of screw rod protective casing and screw rod interfacing part water-stop; The outer end of screw rod protective casing and positive stop water-stop, the distance between the outer face of the positive stop of the outer end of two screw rods equals the thickness of body of wall.
Add that the screw rod protective casing can prevent screw rod and the corrosion of screw rod interfacing part, the convenient dismounting of using the back screw rod.
The utility model further preferably technical scheme be, the screw thread of described screw rod interfacing part is regular screw threads, the screw thread of the inner of corresponding screw rod is regular screw threads, the screw thread of the outer end of screw rod is a trapezoidal thread.
Description of drawings
Fig. 1 is the structural representation of the utility model.
