Abstract
The utility model discloses a water-stop screw rod which is applicable to the underground shear wall or the concrete wall with water-proofing requirement, belongs to the technical field of building components, and comprises three water-stop pieces with holes and one sleeve; the three water-stop pieces are respectively and closely connected with both ends and the central end of the sleeve; the screw rod also comprises a sleeve head, wherein one end of the sleeve head is provided with a small axial hole, the other end of the sleeve head is provided with a big axial hole, and the small axial hole and the big axial hole are communicated, and a plug with an external thread on one end; internal threads which are matched with the external thread of the plug are arranged in both ends of the sleeve; and the big axial hole in the sleeve head is sleeved on both ends of the sleeve in a matched way and the end surface of the sleeve head is closely fitted with the water-stop pieces. Compared with the prior art, the water-stop screw rod has the advantages of convenient structure, material saving, convenient detachment and installation, labor saving, shorter construction hours and lower construction cost, so that an original disposable steel bar threaded rod with high price is reused.
Description
Technical field
The utility model discloses a kind of sealing up screw, be applicable to underground shear wall or have in the concrete wall of waterproof requirement, belong to the building unit technical field.
Background technology
Underground shear wall formwork construction, the member that waterproof requirement is arranged is usually with adopting the finished product sealing up screw.Its structure is the screw rod that one section screw thread is all rubbed at two ends with the hands, anti-skidding set when this section screw thread is reinforcing template; Being installed with a sealing sheet in the middle of the screw rod, is seal welding between sealing sheet and the screw rod, and the sealing sheet symmetry in the middle of the two ends correspondence of screw rod is fixed with the sealing disk, and the sealing disk all closely is provided with the jacking block of detachable installation outward.During use, the screw rod level is placed shear wall, spacing between the jacking block lateral surface of both sides equals the thickness of this shear wall, be that circular piece is positioned on the central point of shear wall, the lateral surface of jacking block is close to mutually with template, and the screw rod two ends are all corresponding passes hole corresponding on the template, the outer girth member of template (as the timber steel pipe etc.) fix with the screw rod at its two ends is staggered, penetration concrete between two side templates treats that concrete setting is a collapsible die.Its shortcoming is that screw rod is disposable use, waste of material is many, the construction cost height, the screw rod that promptly needs to be exposed to surface of wall when form removal cuts off, again jacking block is dug out, then the cavity of jacking block is filled up with cement mortar and equal, when this a series of form removal step is all quite taken a lot of work, caused the problem of engineering construction cost costliness in the wall surface.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of structure simple and direct, and material is saved, and removes and installs sealing up screw easily.
The purpose of this utility model is achieved in that a kind of sealing up screw, comprise three sealing sheets all with holes, a sleeve pipe, three sealing sheets closely are connected in the both ends and the center-side of sleeve pipe respectively, it is characterized in that: also comprise an end establish axial aperture and the other end establish axial macropore and communicate pullover, and one end be provided with externally threaded plug, all be provided with the internal thread that matches with the external screw thread of plug in the two ends of sleeve pipe, pullover interior axial macropore cooperation is placed in the sleeve pipe two ends and pullover this end face is close to mutually with the sealing sheet.
The utility model further is set to:
Described pullover profile is column type or circular platform type.
Described plug, pullover quantity are two.
The other end of described plug is a socket cap, and the outer face of socket cap is provided with the head that opens that matches with the breakdown instrument, and the external diameter of this socket cap is more than or equal to the external diameter of sleeve pipe, again less than the external diameter of sealing sheet.
The described head that opens is the wherein a kind of of positive hexagon post, rectangular column, cross support body, yi word pattern body.
The external thread sleeve of described plug is provided with elastomeric pad.
Described sealing sheet, sleeve pipe, the pullover hard plastics that all adopts are made.
Described plug adopts hard plastics or metal material to make.
During fitting operation, earlier with sleeve pipe and pullover connecting, being about to pullover axial macropore is placed on the sleeve pipe two ends, pullover this end face applying sealing sheet end face, template is close in pullover outer face, pullover axial aperture is taken the installing hole on the axial macropore alignment template, then installing hole and the sleeve pipe of screw thread steel bar from a side template, the pullover installing hole that passes the opposite side template together, with conventional means reinforced steel threaded rod and template, with this kind mode by construction requirement arrange wear after, grouting is built, after treating that striking time arrives, the girth member of the outer screw thread steel bar of elder generation's stripping is extracted the screw thread steel bar then out, opens two side templates, with pullover taking-up, with spanner or other breakdown instruments that matches plug is twisted in the sleeve pipe two ends, by extruding elastomeric pad and being tightly connected, with high-grade cement mortar pullover hole after excavating is filled up getting final product again between the socket cap end face of plug and the box face.
In sum, the utility model advantage compared with prior art is: structure is simple and direct, material is saved, remove and install convenient laborsaving again, shortened construction man-hour, saved construction cost, sleeve pipe etc. adopt plastic production, with low cost, making originally, expensive disposable screw thread steel bar material obtains recycling.
Below in conjunction with description of drawings and specific embodiment the utility model is further specified:
