Description

A kind of novel wall waterproof internal overarm support

Technical field

The utility model relates to a kind of body of wall waterproof internal overarm support, relates in particular to the novel wall waterproof internal overarm support of a kind of high-effective water-proof, leakproof.

Background technology

At present, in the cast-in-place mixed earth construction of building masonry wall, general adopt have flashing must the whole support shuttering that screw rod through walls is set up; After mixed earth was built and finished, not only screw rod can not take out, and the screw rod that stretches out wall outer side makes template and inconvenience dismounting thereof; Need earlier screw rod to be cut away, also need do antirust, benefit slurry processing after the cutting, waste a large amount of steel and human cost; And increased construction cost, incured loss through delay the duration.In addition, the body of rod of existing body of wall waterproof internal overarm support all is solid, need not only waste time and energy, and in order to increase the intensity of connection, cost be higher at two ends with the pull bar that is threaded during use, handles with great difficulty oxidation, is unfavorable for environmental protection.

Having some new technology the problem that screw rod can not take out to be improved now, is the body of wall waterproof Screw arbor with nut at both-ends that the patent document of 200820028937.X just discloses a kind of segmental structure like the patent No., and its pull bar that supports loop bar and outer end is through being threaded; After building end; Only need take off pull bar and get final product, and middle support loop bar is stayed in the body of wall, so dismantle more convenient; But it is solid supporting loop bar, still has the above-mentioned drawback that is threaded and dismantles inconvenience.

Summary of the invention

The purpose of the utility model just is to provide in order to address the above problem the novel wall waterproof internal overarm support of a kind of high-effective water-proof, leakproof.

The utility model is realized above-mentioned purpose through following technical scheme:

The utility model comprise the body of rod, plug, with the supporting plug plug of said plug, said plug is two, is set with the two ends in the said body of rod; The said body of rod is a metallic rod body; Said plug is the plastics head of the trumpet of horn mouth in the outer end; Said plug plug is the Plastic cap plug, and said plug comprises the outer layer plastic ring that lays respectively at the inboard inner plastic ring of said body of rod body wall and the said body of rod body wall outside, and the outer end of said inner plastic ring and said outer layer plastic ring connects as one; The inner of said inner plastic ring is provided with to the outstanding internal projecting ring of the center line of the said body of rod, and the surface of said internal projecting ring is an arcwall face.

The utility model adopts metallic rod body to guarantee tensile strength, has realized multi-sealed waterproof with plug double-deck and that have an internal projecting ring, has guaranteed waterproof, leak preventing effect.During use, pull bar directly passes the through hole of the body of rod of the utility model, need not interconnect, so time saving and energy saving; The Plastic cap end face diameter at metallic rod body two ends contacts with the tight face face of template during construction greater than the aperture of template, prevents that mortar from flowing to the inside of the template outside and the body of rod, is convenient to take off pull bar after construction is accomplished and the plug plug is installed; After construction is accomplished, because directly be not connected between the body of rod and the pull bar, so only need the nut and the chevron card of an end be taken off, can pull out pull bar at the other end, dismounting speed obviously improves.

As preferably, the stage casing of the said body of rod has the seal ring of anti-outer water, and the internal diameter of said seal ring is slightly less than the external diameter of the said body of rod, can guarantee closely to contact between seal ring and the body of rod; As optimal selection, said seal ring is the seal ring of water-swellable.

As preferably, the said body of rod is the iron body, has tensile strength and advantage with low cost concurrently.

Further, the outer end end face of said plug is provided with the end bulge loop, and said end bulge loop is two; The outer surface of said plug is provided with outer bulge loop, and said outer bulge loop is two; The inner surface of the outer layer plastic ring of said plug is provided with the folder bulge loop, and said folder bulge loop is two.End bulge loop, outer bulge loop and folder bulge loop all play multiple waterproof effect.

Particularly; With the direction away from said body of rod mid point is outward direction, and said plug plug comprises outer plug and interior plug, and the outer end diameter of said outer plug is greater than inner diameter; Between the outer end of said outer plug and the inner is smooth transition surface, and the inner end face of said outer plug is provided with outer plug groove; The outer end diameter of plug is less than inner diameter in said, and the outer end of said interior plug places in the outer plug groove of said outer plug.

Further, on the outer end cylinder of said interior plug the rubber waterproof circle is installed, said rubber waterproof circle places between the inner end face and said interior the inner of filling in of said outer plug.

Further, plug groove in the inner end face of said interior plug is provided with, the said interior sealing rod that water-swellable is installed in the groove of filling in, the diameter of said sealing rod is slightly less than the internal diameter of the said body of rod.

The beneficial effect of the utility model is:

The inner waterproof construction of the utility model reaches Pyatyi, is respectively rubber waterproof circle, sealing rod, seal ring, internal projecting ring and folder bulge loop, adds outside end bulge loop, outer bulge loop and plug and holds beyond the Great Wall, can reach 100% waterproof effect; The utility model is simple in structure, easy to process; Simple to operate in work progress, fast assembling and disassembling, laborsaving efficient, waterproof, good leak-proof effect; Reduced waste of material, practiced thrift construction cost, accelerated construction speed, improved economic benefit, helped environmental protection, for the fast development of cast-in-situ wall the realm of building construction lays a solid foundation.
