Abstract
The utility model discloses a rust prevention device for a constructional engineering embedded exposed reinforcement. The rust prevention device comprises a rust prevention cover, a sealing device and an air exhaust hole; an orifice is formed at one end of the rust prevention cover and the rust prevention cover is arranged to cover the outer wall of the exposed reinforcement by virtue of the orifice; the air exhaust hole is formed in a sidewall of the rust prevention cover and only allows air to flow out of the rust prevention cover via the air exhaust hole; the sealing device is an elastic pipe fitting of which the two ends are open, and the two ends of the sealing device sleeve the rust prevention cover, respectively, so as to form sealed contact surfaces with the outer wall of the exposed reinforcement. The rust prevention device is used for solving the problems of weakened building durability and the like due to that the exposed part of the embedded reinforcement at the constructional engineering concrete joint is extremely easy to rust as being exposed in air and affected by rain, sunshine and damp air; the reinforcement rust prevention device provided is capable of protecting the reinforcement against the influence of rain and damp air and retarding the rusting of the constructional engineering embedded exposed reinforcement.
Description
Technical field
The utility model belongs to the device field of construction work, is specifically related to the pre-buried exposed steel bar Rustproofing apparatus of a kind of construction work.
Background technology
When construction work design of reinforced concrete structure and construction, cause the problems such as structure crack for eliminating shrinkage strain in course of hardening, how in reinforced concrete structure, every certain length, deformation joint and rear pouring concrete band to be set, need embedded bar at seam crossing, to ensure the globality of concrete structure more.Deformation joint embedded bar is exposed to the airborne time, determines according to the deformation requirements of structural concrete and construction technology, is not generally 30d～90d not etc., and what have is even longer, and interval is more than 1 year.These exposed steel bars get rusty very soon in air, and along with the lengthening of time, to there is corrosion, slacken the cross section of reinforcing bar, cause after seam crossing concrete construction, overall structure will form weak link at seam crossing, even cause structural deterioration accident, and not carry out antirust special purpose device for the pre-buried exposed steel bar of construction work in prior art.
Therefore,, for overcoming the above problems, need to a kind ofly can carry out the pre-buried exposed steel bar Rustproofing apparatus of antirust construction work to the pre-buried exposed steel bar of construction work easily and effectively.
Utility model content
In view of this, the purpose of this utility model is to be exposed to the problem such as corrosion in air for the pre-buried exposed steel bar of existing construction work, provides a kind of construction work pre-buried exposed steel bar Rustproofing apparatus.
The pre-buried exposed steel bar Rustproofing apparatus of construction work of the present utility model, comprise antirust sleeve, closing device and aspirating hole, antirust sleeve one end is provided with the mouth of pipe and is placed on exposed steel bar outer wall by this mouth of pipe, extract opening is located at antirust sleeve sidewall and is only allowed gas to pass through this extract opening and flows out antirust sleeve, and the Flexible pipe fitting that closing device is both ends open and this closing device two ends are placed on respectively antirust sleeve and exposed steel bar outer wall and form sealing contact surface;
Further, described antirust sleeve comprises pipe shaft section and is one-body molded and insert in the mouth of pipe section in closing device with pipe shaft section;
Further, described closing device comprises soft cotton layer and is sheathed on the rubber layer outside soft cotton layer;
Further, described closing device two ends are wound with adhesive type sealing restraint zone;
Further, described antirust sleeve adopts durable rubber to be made;
Further, described mouth of pipe section outer circumference surface is provided with sealing internal thread;
Further, described closing device inner tubal wall is provided with the sealing external screw thread coordinating with described sealing thread;
Further, described closing device is bellows;
The beneficial effects of the utility model are: the pre-buried exposed steel bar Rustproofing apparatus of construction work of the present utility model, antirust sleeve is by after exposed steel bar parcel, by closing device, the antirust sleeve mouth of pipe is shut, by existing exhaust plant, the gas in antirust sleeve is extracted out from extract opening again, make antirust sleeve closely be wrapped in exposed steel bar surface and in antirust sleeve, form a vacuum wall body, thereby blocking-up reinforcing bar contacts with air, slow down the corrosion of reinforcing bar, the pre-buried exposed steel bar Rustproofing apparatus of construction work of the present utility model can effectively slow down the corrosion of exposed steel bar, avoid after the concrete construction of steel and concrete structure seam crossing, seam crossing is because of strength deficiency recurring structure malicious event, the utility model has overcome existing construction work concrete joint embedded bar exposed parts, because being exposed in air, drenched with rain, the impact of Exposure to Sunlight and moisture laden air, very easily get rusty, if be exposed to for a long time in air, even there is corrosion of steel bar, bottom structure bearing capacity falls, affect structural safety, slacken the problems such as building durability, can effectively block rainwater and the impact of wet damp air on reinforcing bar.
Brief description of the drawings
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure, pre-buried exposed steel bar 5 Rustproofing apparatus of construction work in the present embodiment, comprise antirust sleeve 4, closing device 2 and aspirating hole 9, antirust sleeve 4 one end are provided with the mouth of pipe and are placed on exposed steel bar 5 outer walls by this mouth of pipe, extract opening is located at antirust sleeve 4 sidewalls and is only allowed gas to pass through this extract opening and flows out antirust sleeve 4, and the Flexible pipe fitting that closing device 2 is both ends open and this closing device 2 two ends are placed on respectively antirust sleeve 4 with exposed steel bar 5 outer walls and form sealing contact surface.
In the present embodiment, described antirust sleeve 4 comprises pipe shaft section 3 and is one-body molded and insert in the mouth of pipe section 6 in closing device 2 with pipe shaft section 3, closing device 2 two ends form sealing contact surface with mouth of pipe section 6 and exposed steel bar 5 surfaces respectively, thereby make the interior formation seal chamber of antirust sleeve 4.
In the present embodiment, described closing device 2 comprises soft cotton layer 7 and is sheathed on the rubber layer 8 outside soft cotton layer 7, the flexible thin-walled rubber of closing device 2 can compress rebar surface, and space between the further filling thin-walled rubber of soft cotton material and reinforcing bar, and then significantly promote the sealing performance in antirust sleeve 4.
