Abstract
The utility model provides a shear force wall open type is faced frontier defense and is protected fastener, face frontier defense protect the fastener include to draw the screw rod, to drawing nut, steel pipe and sealing iron sheet (4), it is equipped with two holes on the iron sheet to seal, be the open type twin -screw to drawing the screw rod right -hand member, the utility model discloses simple structure, not only can effectual solution construction off -the -shelf protection problem, has reduced moreover and has set up time spent of facing the limit, has reduced the firm degree that construction cost has increased the protection simultaneously, the utility model discloses simple to operate is swift, easy operation is clear, not influenced by the external environment condition.
Description
Technical field
The utility model relates to one and faces frontier defense protection unit, and especially a kind of shear wall open type is faced frontier defense and protected fastener.
Background technology
Nowadays the fast development of Chinese architecture, improving constantly of land use rate has impelled the construction of high-rise and super highrise building to develop, also the eminence in construction is had higher requirement safely simultaneously, the working measure of thing and high-rise working safety is fallen as preventing high altitude, facing the stable and reliability that frontier defense protects plays a part absolute, it is existing that to face limit construction technology for protection simple and crude, pound into expansion bolt as dug hole on shear wall, or pound into precast reinforced finished product, though these methods meet code requirement but construct simple and crude, and be unfavorable for MAT'L recycling, cause a large amount of waste.
Summary of the invention
For solving an above existing difficult problem, the utility model discloses a kind of shear wall open type and facing frontier defense and protect fastener.
A kind of shear wall open type is faced frontier defense and is protected fastener, described in face frontier defense and protect that fastener comprises Screw arbor with nut at both-ends, to drawing nut, steel pipe and sealing iron plate (4), described sealing iron plate is provided with two circular cavities, and described Screw arbor with nut at both-ends right-hand member is open type twin-screw.
A nearly step, described steel pipe two ends are positioned at the opening of Screw arbor with nut at both-ends right-hand member, and Screw arbor with nut at both-ends middle-end is positioned at shear wall, left end is provided with and fixes also passing through drawing nut to be fixed drawing nut, right-end openings formula twin-screw to pass hole of self.
A nearly step, described sealing iron plate is rectangle.
Beneficial effect: the utility model structure is simple; effectively can not only solve the protection problem of construction finished product; and decrease set up face limit used time, decrease the firm degree that construction cost adds protection simultaneously; the utility model is quick and easy for installation, simple to operate to be understood, does not affect in construction by external environmental condition.

Wherein, 1, Screw arbor with nut at both-ends, 2, to drawing nut, 3, steel pipe, 4, sealing iron plate, 5, hole, 6, indoor wall, 7, outdoor wall surface.
Detailed description of the invention
By reference to the accompanying drawings, the utility model is described in further details.
As shown in the figure, a kind of shear wall open type is faced frontier defense and is protected fastener, described face frontier defense protect fastener comprise Screw arbor with nut at both-ends 1, to draw nut 2, steel pipe 3 and sealing iron plate 4, described sealing iron plate 4 is provided with two circular cavities 5, described Screw arbor with nut at both-ends 1 right-hand member is open type twin-screw, described steel pipe 3 two ends are positioned at the opening of Screw arbor with nut at both-ends 1 right-hand member, Screw arbor with nut at both-ends 1 middle-end is positioned at shear wall, left end is provided with and fixes also passing through drawing nut 2 to be fixed drawing nut 2, right-end openings formula twin-screw to pass hole 5 of self, and described sealing iron plate 4 is rectangle.
Embodiment: before installation the utility model, prepare the sleeve pipe meeting shear wall specification, reinforcing bar is placed in sleeve pipe, sleeve pipe both sides make to seal with adhesive tape, before not installing to inside wall formwork after the reinforcing bar side of shear wall has been pricked, sleeve pipe side is pricked to the height meeting code requirement, after the form removable of shear wall, the adhesive tape removing sleeve pipe both sides takes out reinforcing bar, insert Screw arbor with nut at both-ends 1, steel pipe 3 inserts in the opening of Screw arbor with nut at both-ends 1 open type twin-screw, the right-hand member of Screw arbor with nut at both-ends 1 inserts hole 5, use drawing nut 2 to be fixed on shear wall by Screw arbor with nut at both-ends 1, first will remove drawing nut 2 during dismounting, then open type being faced frontier defense protection unit takes off in indoor fractionation Screw arbor with nut at both-ends 1, steel pipe 3 and sealing iron plate.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of utility model is defined by appending claims and equivalent thereof.
