Abstract
The utility model relates to a waterproof bolt. The waterproof bolt comprises a center screw and a rubber waterproof strip sleeving the middle of the center screw. The rubber waterproof strip is shaped in a trapezoid with small end up, the center screw is connectively welded with sleeves, the sleeves are provided with inner threads inside, and the outer walls of the sleeves are provided with concave-convex waterproof layers. The waterproof bolts further comprises assisting rods provided with outer threads matched with the inner threads, trapezoidal sleeve blocks sleeve the assisting rods, the sections of the outer ends of the trapezoidal sleeve blocks are larger than those of the inner ends of the same, and the assisting rods are fittingly provided with fixed fasteners and fixed nuts. The waterproof bolt has the advantages of good waterproof effect, convenience in demounting and high material recycling rate.
Description
Technical field
The utility model relates to a kind of building water-proof bolt.
Background technology
In building operations, before basement and common exterior wall are built, transverse screw is set in bar construction, to disperse lateral pressure.The screw rod that stretches out body of wall outside after concreting adopts cutting mode to remove, and this has caused the waste of building materials, and the external force of cutting makes to occur gap between screw rod and concrete simultaneously, and the external world has water easily along screw rod, to enter interior wall, does not reach waterproof requirement.
Existing waterproof bolt arranges the sealing rod of steel or rubber in the middle of screw rod, only depends on its waterproof effect of common sealing rod very limited, and can not solve the seepage problem of screw rod and metope junction.
Through retrieval, Chinese patent " can the turnover water stopping bolt " (patent No.: 201120337377.8) disclose a kind of waterproof bolt, the dismounting of waterproof bolt and the recycling of part-structure have been realized, but this patent end portion will overcome concrete frictional resistance when dismounting, there is certain difficulty in dismounting, and only relies on that pad waterproof effect is set is still limited.
Utility model content
Technical problem to be solved in the utility model is: provide that a kind of simple in structure, easy to use, water proofing property is strong, waterproof bolt that can partially recycled utilization.
The technical scheme that the utility model solves its technical problem employing is:
A kind of waterproof bolt, it is characterized in that: comprise center bolt, be enclosed within the rubber waterproof bar at center bolt middle part, it is up-narrow and down-wide trapezoidal that described rubber waterproof bar becomes, and center bolt welding is connected with sleeve, described sleeve inner arranges internal thread, outer wall is provided with concavo-convex alternate aquiclude, also comprises auxiliary rod, and described auxiliary rod is provided with the external screw thread supporting with internal thread of sleeve, described auxiliary rod outer cover is provided with trapezoidal cover piece, and the outer end section of described trapezoidal cover piece is greater than interior end section.
Described rubber waterproof bar material is hydro-expansive rubber.
Described trapezoidal cover piece is wooden.
The beneficial effects of the utility model are:
(1) waterproof effect is good: waterproofing mortar can be filled up in the space after trapezoidal cover piece is deducted, and can effectively stop water to infiltrate from metope; The concavo-convex alternate aquiclude of sleeve outer wall can be strengthened the distance that water passes through, the moisture that absorption portion is infiltrated; Rubber waterproof ring water-swellable, water capable of blocking permeates to interior wall, and rubber waterproof ring is arranged to up-narrow and down-wide trapezoidal shape and is conducive to block water and because gravity flows, crosses rubber waterproof ring;
(2) for convenience detach: owing to being provided with the threaded sleeve of inwall, auxiliary rod can utilize the easily handling that are threaded, and avoids contacting with concrete direct friction, and during dismounting, resistance is less;
(3) material yield rate is high: after auxiliary rod dismounting, can realize recycling, and cost-saving.
The utility model is simple in structure, easy to operate, and it is convenient to dismantle, and has good waterproof effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the state diagram of the present utility model after body of wall is built;
In accompanying drawing, 1 center bolt, 2 rubber waterproof rings, 3 sleeves, 4 auxiliary rods, 5 trapezoidal cover pieces, 6 wall forms.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further illustrated.
A kind of waterproof bolt of the present embodiment, it comprises center bolt 1, be enclosed within the rubber waterproof ring 2 at center bolt 1 middle part, up-narrow and down-wide trapezoidal of 2 one-tenth, described rubber waterproof ring, described center bolt 1 is welded to connect sleeve 3 outer walls, described sleeve 3 inside arrange internal thread, and the outer wall of described sleeve 3 is provided with concavo-convex alternate aquiclude 7, and described aquiclude 7 is formed in one with sleeve 3; Also comprise auxiliary rod 4, described auxiliary rod 4 is provided with the external screw thread supporting with sleeve 3 internal threads, and described auxiliary rod 4 outer cover are provided with trapezoidal cover piece 5, and the outer end section of described trapezoidal cover piece 5 is greater than interior end section.
Described rubber waterproof ring 2 materials are hydro-expansive rubber, and described hydro-expansive rubber meets the hydro-expansive rubber production standard of stipulating in GB/T18173.3-2002.
Described trapezoidal cover piece 5 is wooden.
3, described center bolt 1 and sleeve are carbon dioxide welding, without welding slag, and no-welding-seam.
The specific works process of the present embodiment is: center bolt 1 is erected between reinforced frame, screw sleeve 3 and auxiliary rod 4, trapezoidal cover piece 5 is enclosed within on auxiliary rod 4 and is fitted to the little one end of sectional area and sleeve 3, one end that trapezoidal cover piece 5 sectional areas are large and wall form 6 laminatings; Concrete perfusion, after concrete coagulation, unscrews auxiliary rod 4 to screwing out metope, and because 3, auxiliary rod 4 and sleeve are for being threaded, but not auxiliary rod 4 directly contacts with concrete, reduces the resistance that auxiliary rod 4 is withdrawn from; Remove after wall form 8, take off trapezoidal cover piece 5, to the interior perfusion waterproofing mortar of sleeve 3, fill and lead up the space of trapezoidal cover piece 5 positions, do again afterwards polyurethane water-proof layer, can effectively play waterproof effect.When exterior wall has water to infiltrate, once waterproofing course does not have waterproof effect completely, the concavo-convex alternate aquiclude 7 of sleeve 3 outer wall can increase distance that water passes through, increase the contact area of sleeve 3 and water, effectively blocks water and infiltrates to interior wall; When water, to continue endosmosis fashionable, be arranged on rubber waterproof ring 2 water-swellables of center bolt 1 central authorities, be close to concrete, blocking-up water continues to infiltrate, rubber waterproof ring 2 is set to up-narrow and down-wide trapezoidal, and anti-sealing moves and crosses rubber waterproof ring 2 and enter interior wall along rubber waterproof ring 2 because of Action of Gravity Field.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to embodiment illustrated herein, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
