Description
Technical field
The utility model belongs to the construction timber field, specifically, relates to a kind of improved just loading and unloading type body of wall waterproof Screw arbor with nut at both-ends.
Background technology
Its structure of highrise building mostly is that frame is cut, shear wall structure, utility box type or raft foundation, and most of engineering is equipped with basement.In outer wall of basement Cast-in-place concrete work progress, for keeping the spacing of two side templates, bear concrete lateral pressure and other loads, the general whole Screw arbor with nut at both-ends through walls that has the sealing sheet that adopt, strengthen the lateral strength and the rigidity of template, solve the lateral pressure that the mobile and vibration of Cast-in-place concrete brings template and support system, prevent that template and support system from occurring running mould, the mould that rises, avoid Cast-in-place concrete member outward appearance mass defect to occur.But, use whole traditional Screw arbor with nut at both-ends through walls, the sector-meeting of the comparatively complicated welding sealing of installation process causes certain pollution to environment, and because the restriction of solder technology, level, its water resistance is difficult to guarantee, is easy to generate the seepage phenomenon, for later external wall waterproof stays hidden danger; And in concrete casting complete rear pattern plate teardown phase, Screw arbor with nut at both-ends can't take out again, the screw rod that is exposed at the body of wall both sides outward passes template, increased the dismounting difficulty of template, strengthened the active loss of template, the screw rod exposed parts needs the gas cutting excision, has wasted great deal of steel, increase construction cost, prolonged the duration.
At above-mentioned defective, existing utility model patent: the patent No. is 201120358714.1, patent name is the patent of " just loading and unloading type body of wall waterproof Screw arbor with nut at both-ends ", its technical scheme is: include drawing interior stay tube, interior stay tube shutoff support cap, seal ring, pull bar and nut, to the two ends inwall of stay tube in drawing the pull bar that respectively is spirally connected with nut, and in two termination point casings to stay tube in drawing are connected to stay tube shutoff support cap, interior stay tube shutoff support cap closely contacts with pull bar, and seal ring closely hoop is enclosed within drawing the inner support tube outer surface.Stifled to also being provided with water shutoff in the stay tube in drawing, water shutoff is stifled also adopts the existing novel water-swellable material that is used to seal to make.Such design, though improved the performance of antiseep, processing technology has improved, and causes cost to raise, complete in addition silk screw rod is tightened difficulty, occurs easily twisting not tight situation, influences the result of use of Screw arbor with nut at both-ends.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defective, provide a kind of simple in structure, easy to process, tighten and good sealing effect, the improved just loading and unloading type body of wall waterproof Screw arbor with nut at both-ends that reduces cost easily.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of improved just loading and unloading type body of wall waterproof Screw arbor with nut at both-ends, include drawing interior stay tube, two ends to stay tube in drawing are respectively arranged with interior stay tube shutoff support cap, and be connected with pull bar respectively at two ends to stay tube in drawing, pull bar is provided with nut, it is characterized in that: described middle part to stay tube in drawing is provided with eel-like figure portion, and the diameter of eel-like figure portion is less than the diameter to stay tube in drawing; Eel-like figure portion one side on the stay tube in drawing seal ring being installed.
As a kind of improvement, two ends of described pull bar are respectively arranged with external screw thread, and the inboard tube wall of interior stay tube shutoff support cap is provided with internal thread, pull bar with to drawing the inner support gas thread to be connected.
As a kind of improvement, described pull bar is not provided with externally threaded position and is provided with some groups of gap groups.
As a kind of improvement, described gap group comprises two gap, and two gap are symmetricly set on the pull bar.
As a kind of improvement, described two ends to stay tube in drawing are respectively arranged with hold down gag.
As a kind of improvement, described hold down gag is the some grooves that are arranged on two ends of stay tube in drawing.
Owing to adopted technique scheme, compared with prior art, the utility model is to utilize special equipment to extrude an eel-like figure portion in the centre position to stay tube in drawing, eel-like figure portion role is stifled the same with water shutoff, but the eel-like figure portion processing technology that extrudes is simple, the production efficiency height has reduced cost of production.In addition, pull bar just is provided with screw thread at two ends, and the centre is provided with gap, and gap can make things convenient for the clamping of instrument, can guarantee to tighten, cooperate the groove with pressuring action again, has fully guaranteed pull bar and sealing effectiveness to stay tube in drawing.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments simultaneously.
