Description
Technical field the utility model relates to a kind of Screw arbor with nut at both-ends through walls, is specifically related to a kind of high-effective water-proof Screw arbor with nut at both-ends.
Background technology need support and formboard fastening with Screw arbor with nut at both-ends through walls in the building wall in-situ casting and constructing.At present, in the exterior wall cast-in-situ concrete construction of building basement, the general whole screw rod through walls that has the sealing sheet that adopt.Adopt this whole screw rod through walls, after concrete pouring is finished, the screw rod that stretches out wall outer side must excise one by one with modes such as gas cuttings, so not only waste time and energy, waste steel, and cause the template dismounting difficult, cause the breakage of template to scrap, increase construction cost, reduce speed of application and metope quality.In recent years, occurred a kind of can reusable Screw arbor with nut at both-ends, solved the waste problem of steel, template and manpower preferably.But, this can reusable Screw arbor with nut at both-ends, the part that is embedded in body of wall is a hollow section, though be anti-sealing seepage from hollow section, hydro-expansive rubber sealing piece is set in hollow section, and hollow section pushed, but extruding back hollow section radially is out of shape very big, fast its distortion of sealing of putting into pipe in theory before the extruding is unpredictable, can't guarantee fully that more itself and tube wall especially form the dash sealing in the two ends of the tube section after flattening, therefore, be embedded in the hollow section of body of wall and may form leakage passage.On the outer wall of hollow section, be with the hydro-expansive rubber seal ring, in the process of concreting, concrete may enter in the slit between hydro-expansive rubber seal ring and the outer tube wall, forming concrete directly contacts with outer tube wall, to produce the slit after the concrete setting, and make the seal ring on the hollow section outer wall completely lose the sealing function.And the life-span of hydro-expansive rubber is limited, after after a while, can wear out, damage or characteristic change, and might cause the sealing disabler.Some other problem that this Screw arbor with nut at both-ends also exists in actual applications.A problem is that its detachable end is connected with the intermediate hollow tube portion by screw thread, in the process of fluid concrete, concrete often drains to the junction of detachable end and intermediate hollow pipe by the slit between template and the supporting pad, after the concrete setting, cause screw rod dismounting difficulty.Another problem is to need behind the body of wall casting complete a large amount of holes that Screw arbor with nut at both-ends stays on body of wall are handled, usually need to adopt material such as mortar in the practical application with bore hole stemming, but this process wastes time and energy, work efficiency is extremely low, though easier than the cutting steel bar end, also cause manually and the significant wastage of material.
The summary of the invention the purpose of this utility model is to provide a kind of economical with materials, multiple waterproof, easily detachable high-effective water-proof Screw arbor with nut at both-ends.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of high-effective water-proof Screw arbor with nut at both-ends, comprise two pull bars and be arranged between two pull bars and the support member that is connected with two pull bars, described support member comprises two hollow sections and is arranged between two hollow sections and the sealing core that is connected with hollow section, the sealing core is provided with sealing sheet and the joint ring thereof that flexible material is made, sealing sheet joint ring endoporus is taper, two hollow sections screw the back and form sealing with the extruding of sealing plate plane, when hollow section screws in and sealing sheet joint ring cone-shaped inner hole interference fit form sealing once more; Hollow section is connected with pull rod screw, and support member and pull bar junction are provided with locating pad, and the pull bar tail end is provided with the spanner platform, and nut is set on the pull bar.
The end termination that described pull bar is connected with hollow section is provided with protective sleeve.
The waterproof sealing plug of being furnished with its endoporus interference fit is paid somebody's debt and expected repayment later in described location.And on the waterproof sealing plug, be provided with locating ring.
A kind of high-effective water-proof Screw arbor with nut at both-ends that the utility model provides, its pull bar is reusable, need not the gas cutting excision, and economical with materials reduces cost, and is time saving and energy saving.Sealing core in the support member is solid, radially be provided with sealing sheet and joint ring thereof that flexible material is made on the sealing core, after two hollow sections screw, the crimp of sealing sheet is formed a resealing on the sealing plate plane, and form second resealing with sealing sheet joint ring, double seal makes inside and outside penetrating passage isolate mutually, guarantees stagnant water effect.In addition, the end termination that pull bar is connected with hollow section is provided with protective sleeve, anti-adhesion, quick detachable.After construction is finished, adopt the tie rod hole on the waterproof sealing plug reparation metope, waterproof sealing plug and locating pad hole wall are interference fit, form the sealing sealing once more, and the design of waterproof sealing plug has self-locating function, guarantee that the waterproof sealing plug can not move vertically, and its end face flushes with metope.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Fig. 2 repairs the view of metope for the waterproof sealing plug.
Among the figure: the 1-pull bar; The 2-support member; The 3-hollow section; 4-sealing core; 5-sealing sheet; The 6-locating pad; The 7-nut; The 8-protective sleeve; 9-spanner platform; 10-sealing sheet joint ring; 11-waterproof sealing plug.
The specific embodiment as shown in Figure 1 be an embodiment of the present utility model, a kind of high-effective water-proof Screw arbor with nut at both-ends, it comprises two pull bars 1 and is arranged between two pull bars 1 and the support member 2 that is threaded with two pull bars 1, pull bar 1 is a solid hopkinson bar, support member 2 comprises two hollow sections 3 and is arranged between two hollow sections 3 and the sealing core 4 that is threaded with hollow section 3 that sealing core 4 is a solid hopkinson bar.Sealing core 4 is provided with sealing sheet 5 and the joint ring of being made by flexible material 10 thereof, sealing sheet joint ring 10 endoporus are taper, two hollow sections 3 screw the back and form sealing with the extruding of sealing sheet 5 planes, when hollow section 3 screws in and the cone-shaped inner hole interference fit of sealing sheet joint ring 10 form sealing once more.Solid sealing core 4 and sealing sheet 5 and joint ring 10 thereof have sealed inside and outside penetrating passage, guarantee stagnant water effect.Hollow section 3 is threaded with pull bar 1, and support member 2 is provided with locating pad 6 with pull bar 1 junction, and wing nut 7 is set on the pull bar 1.The end termination that pull bar 1 is connected with hollow section 3 is provided with protective sleeve 8; protective sleeve 8 is a plastic sheath; prevent in the process of fluid concrete; concrete drains to the junction of pull bar 1 and hollow section 3 by the slit between template and the locating pad 6, causes pull bar 1 and hollow section 3 inter-adhesive, not quick detachable.Pull bar 1 tail end is provided with spanner platform 9, can unload lower link 1 with spanner.
