Description
Technical field
The invention belongs to the device field of construction work, be 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, the problems such as structure crack are caused for eliminating shrinkage strain in course of hardening, how in reinforced concrete structure, deformation joint and rear pouring concrete band to be set every certain length, need embedded bar at seam crossing, to ensure the globality of concrete structure more.Deformation joint embedded bar exposes the aerial time, determines according to the deformation requirements of structural concrete and construction technology, and be not generally 30d ~ 90d not etc., what have is even longer, more than 1 year, interval.These exposed steel bars get rusty in atmosphere very soon, and along with the lengthening of time, corrosion will be there is, slacken the cross section of reinforcing bar, after causing 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 a kind ofly to 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.
Summary of the invention
In view of this, the object of the invention is to expose the problems such as corrosion in atmosphere for the pre-buried exposed steel bar of existing construction work, provide 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 invention, 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 flow out antirust sleeve by this extract opening, and closing device is the Flexible pipe fitting of both ends open and this closing device two ends are placed on antirust sleeve and exposed steel bar outer wall respectively and form sealing contact surface;
Further, described antirust sleeve comprises pipe shaft section and and the mouth of pipe section that insert in closing device in one-body molded 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 external screw thread;
Further, described closing device inner tubal wall is provided with the sealing internal thread coordinated with described sealing external screw thread;
Further, described closing device is bellows;
The invention also discloses a kind of construction work pre-buried exposed steel bar Rustproofing apparatus that utilizes and carry out the antirust method of pre-buried exposed steel bar, comprise the following steps:
A, antirust sleeve is placed on the pre-buried exposed steel bar of building;
B, antirust sleeve mouth of pipe section to be inserted in closing device;
C, utilize existing exhaust plant to extract air in antirust sleeve out, make to form vacuum in antirust sleeve.
The invention has the beneficial effects as follows: the pre-buried exposed steel bar Rustproofing apparatus of construction work of the present invention, after exposed steel bar wraps up by antirust sleeve, 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, antirust sleeve is made closely to be wrapped in exposed steel bar surface and to form a vacuum wall body in antirust sleeve, thus block the contact of reinforcing bar and air, slow down the corrosion of reinforcing bar, the pre-buried exposed steel bar Rustproofing apparatus of construction work of the present invention effectively can slow down the corrosion of exposed steel bar, after avoiding the concrete construction of steel and concrete structure seam crossing, seam crossing is recurring structure malicious event because of strength deficiency, instant invention overcomes existing construction work concrete joint embedded bar exposed parts, because exposing in atmosphere, drenched with rain, the impact of Exposure to Sunlight and moisture laden air, very easily get rusty, expose in atmosphere if long-time, even there is corrosion of steel bar, bottom structure bearing capacity falls, affect structural safety, slacken the problems such as building durability, effectively can block rainwater and wet damp air to the impact of reinforcing bar.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Fig. 1 is structural representation of the present invention, as shown in the figure, construction work in the present embodiment pre-buried exposed steel bar 5 Rustproofing apparatus, comprise antirust sleeve 4, closing device 2 and aspirating hole, antirust sleeve 4 one end is provided with the mouth of pipe and is placed on exposed steel bar 5 outer wall by this mouth of pipe, extract opening 9 is located at antirust sleeve 4 sidewall and is only allowed gas to flow out antirust sleeve 4 by this extract opening 9, and closing device 2 be the Flexible pipe fitting of both ends open and this closing device 2 two ends are placed on antirust sleeve 4 and exposed steel bar 5 outer wall respectively and form sealing contact surface.
In the present embodiment, described antirust sleeve 4 comprises pipe shaft section 3 and and the mouth of pipe section 6 that insert in closing device 2 in one-body molded 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 surface respectively, thus make to form seal chamber in antirust sleeve 4.
In the present embodiment, the rubber layer 8 that described closing device 2 comprises soft cotton layer 7 and is sheathed on outside soft cotton layer 7, the flexible thin-walled rubber of closing device 2 can compress rebar surface, and the 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.
