Abstract
The utility model discloses a kind of sealing up screw for building, comprise screw body, the two ends of described screw body are provided with screw thread, the middle part of described screw body is provided with middle part sealing piece, the both ends of described screw body and be respectively equipped with end sealing piece in the inner side of described screw thread, the outside of described screw thread is provided with nut, and the both ends of described screw body are also provided with pullover.Middle part of the present utility model sealing piece is one-body molded with screw body described in the sealing piece of end or be connected by draw-in groove, and described middle part sealing piece and end sealing piece adopt epoxy polyester or glass fibre structure.The utility model structure is simple, reasonable in design, long service life, removes and installs conveniently, time saving and energy saving, and the screw rod of this structure has good waterproof effect.
Description
Technical field
The utility model belongs to construction project technical field, is specifically related to a kind of sealing up screw for building.
Background technology
Underground shear wall formwork construction, has the component of waterproof requirement usually with adopting finished product sealing up screw.Its structure is the screw rod that one section of screw thread is all rubbed at two ends with the hands, and this section of screw thread is set by anti-skidding during reinforcing template; Being installed with a sealing piece in the middle of screw rod, is seal welding between sealing piece and screw rod, and the sealing piece symmetry in the middle of the two ends correspondence of screw rod is fixed with sealing disk, and sealing disk is all closely provided with the detachable jacking block installed outward.During use, screw stem water is flat in shear wall, spacing between the jacking block lateral surface of both sides equals the thickness of this shear wall, namely circular piece is positioned on the central point of shear wall, the lateral surface of jacking block is close to mutually with template, and screw rod two ends are all corresponding to hole corresponding in template, and the girth member (as timber steel pipe etc.) outside template fixes with the screw rod at its two ends is staggered, penetration concrete between two side templates, treats concrete setting and collapsible die.Its shortcoming is screw rod is single use, waste of material is many, construction cost is high, namely the screw rod being exposed to surface of wall need be cut off when form removal, again jacking block is dug out, then the cavity cement mortar of jacking block to be filled up and equal in wall surface, when this series of step of removal is all quite taken a lot of work, cause the problem of Construction Cost costliness.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provides a kind of structure simple, reasonable in design, long service life, removes and installs convenience, time saving and energy saving sealing up screw for building.
Technical scheme: one described in the utility model sealing up screw for building, comprise screw body, the two ends of described screw body are provided with screw thread, the middle part of described screw body is provided with middle part sealing piece, the both ends of described screw body and be respectively equipped with end sealing piece in the inner side of described screw thread, the outside of described screw thread is provided with nut, and the both ends of described screw body are also provided with pullover.
As optimization, described middle part sealing piece is one-body molded with described screw body with end sealing piece or be connected by draw-in groove.
As optimization, described middle part sealing piece and end sealing piece adopt epoxy polyester or glass fibre structure.
As optimization, the diameter of described middle part sealing piece is greater than the diameter of described end sealing piece.
As optimization, described middle part sealing piece and end sealing piece are rectangle or circular configuration.
As optimization, the thickness of described middle part sealing piece and end sealing piece is 2-5mm.
As optimization, described end sealing piece is 30-50cm apart from the distance of described middle part sealing piece.
Beneficial effect: the utility model structure is simple, reasonable in design, long service life, removes and installs conveniently, time saving and energy saving, and the screw rod of this structure has good waterproof effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The sealing up screw for building of one as shown in Figure 1, comprise screw body 1, the two ends of described screw body 1 are provided with screw thread, the middle part of described screw body 1 is provided with middle part sealing piece 2, the both ends of described screw body 1 and be respectively equipped with end sealing piece 3 in the inner side of described screw thread, the outside of described screw thread is provided with nut, and the both ends of described screw body 1 are also provided with pullover.
As the further optimization of technique scheme, described middle part sealing piece 2 is one-body molded with described screw body 1 with end sealing piece 3 or be connected by draw-in groove.Described middle part sealing piece 2 and end sealing piece 3 adopt epoxy polyester or glass fibre structure.The diameter of described middle part sealing piece 2 is greater than the diameter of described end sealing piece 3.Described middle part sealing piece 2 and end sealing piece 3 are rectangle or circular configuration.The thickness of described middle part sealing piece 2 and end sealing piece 3 is 2-5mm.Described end sealing piece 3 is 30-50cm apart from the distance of described middle part sealing piece 2.
