Abstract
The utility model discloses a waterproof screw for concrete wall construction, which is formed by connecting an integrated internal and external waterproof nut with inner thread and two straight-through screws at two ends, wherein the straight-through screws are provided with fixing nuts. The waterproof screw for concrete wall construction is structurally characterized in that intercepting threaded joint nuts are utilized for construction of walls, by utilizing the integrated internal and external waterproof nut, water leakage in early casting concrete construction can be avoided effectively. A positioning slurry preventive ring is mounted at the outer end of a protective tube, thereby eliminating slurry leakage due to large seams in the conventional welding process. The waterproof screw for concrete wall construction is reasonable in design, simple in structure, fine in anti-leakage property and convenient in mounting and dismounting.
Description
Technical field
The utility model relates to a kind of body of wall to be constructed and uses screw, particularly a kind of be applicable to bear be connected and fixed the template screw in all kinds of structure concrete components that draw, press two-way function power.
Background technology
At present, in all kinds of structure cast-in-situ concrete constructions, generally use a kind of centre to be welded with flashing or have water proof ring and screw that both sides are welded with spacer bars fixes the connection masterplate, spacer bars also need be put wood particle outward, after concrete pouring was intact, screw can't take out, and the screw that stretches out outside the body of wall makes the bad dismounting of template, also need after the form removal wood particle after draw out within the walls, excision exposes screw.The shortcoming that prior art is deposited: the one, cause the waste just of big dimension; The 2nd, the flashing welding procedure undercut can occur, leak weldering, rosin joint phenomenon, thereby the stretching resistance performance in the screw construction is just being followed in influence, occurs after the construction oozing, drainage; The 3rd, the spacer bars slit is big, easy spillage in the construction; The 4th, plain nut is easily loosening revolution under the vibrations of vibrating head in construction, and occur rising mould or quick-fried mould phenomenon influence workmanship.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of reasonable in design, simple in structure, bear that pulling force is big, anti-seep water performance body of wall good, easy installation and removal is constructed and used screw.
The utility model is connected to form by waterproof internal threaded nut inside and outside the integral type 1 and two straight-through screws 3 that are located at two ends.Socket joint has screw protection tube 2 on the inside and outside waterproof internal threaded nut 1 of integral type, and the outer end of screw protection tube 2 is equipped with the anti-slurry circle 5 in location, and straight-through screw 3 two ends are equipped with hold-down nut 4.
The utility model has following advantage compared with the prior art: adopt the inside and outside waterproof internal threaded nut of integral type, compare original welding flashing, spacer bars and methods such as filling waterproofing materials, water proof ring, can effectively stop the construction after ooze, drainage, simplify the structure, screw is reusable, thereby also saved material, reduced cost.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the structural representation of the inside and outside waterproof internal threaded nut 1 of the utility model integral type.
The specific embodiment
Sequence number is represented respectively among the figure: the inside and outside waterproof internal threaded nut 1 of integral type, screw protection tube 2, straight-through screw 3, hold-down nut 4, the anti-slurry circle 5 in location.
The utility model will be further described below in conjunction with accompanying drawing.
A kind of concrete wall is as shown in Figure 1 constructed and is used the waterproof screw; it is formed by connecting by waterproof internal threaded nut inside and outside the integral type 1 and two straight-through screws 3 that are located at two ends; socket joint has screw protection tube 2 on waterproof internal threaded nut 1 inside and outside the integral type; the outer end of screw protection tube 2 is equipped with the anti-slurry circle 5 in location, and straight-through screw 3 two ends are equipped with hold-down nut 4.Body of wall is with the threaded coupler nut that intercepts water, and because of having adopted waterproof internal threaded nut 1 inside and outside the integral type, effectively stopped the leakage infiltration phenomenon that occurs in the first pouring concrete construction.The outer end of protection tube 2 is equipped with the anti-slurry circle 5 in location, has stopped the spillage phenomenon that occurs greatly because of traditional welding technology slit.Straight-through screw 3 adopts novel coarse-pitch thread technology, can bear more strong pulling force, has prevented the generation because of the quick-fried mould phenomenon of stripped thread.Hold-down nut 4 adopts tiltedly flower seam nut, prevents to turn round loosening phenomenon because of vibrations in the construction.
Claims (4)
