A kind of reinforcing and anti-leakage structure that on existing steel concrete wall, punches
Technical field
The utility model relates to a kind of reinforcing and anti-leakage structure, particularly relates to a kind of reinforcing and anti-leakage structure that punches on existing steel concrete wall.
Background technology
In the work progress of industry, the steel reinforced concrete pool body pool wall of civilian construction or reinforced concrete wall, through regular meeting because design defect or reason such as construction omission etc. are missed the reserving hole of pipeline, thereby need pool wall or walls concrete build finish after at punch poling and reinforce with antiseep and handle of pool wall or body of wall; Particularly in reconstruction, the extension project, the reinforcing and the antiseep at the poling place that punches on existing steel concrete pool wall or body of wall are handled of common occurrence especially.
When on existing steel concrete pool wall or reinforced concrete wall, punching, need to consider liquid or pond (wall) outer underground seepage problem in the steel reinforced concrete pool, when simultaneously requiring perforate hole diameter when pool wall or wall greater than 300mm according to current specifications, need take strengthening measure to the hole place, to reduce the slacken effect of hole to the intensity of pool wall or body of wall.
The treatment technology that punches on steel concrete pool wall or reinforced concrete wall at present mainly contains following two kinds of schemes: first kind of processing scheme: water string requires to make, install according to existing national standard atlas, and hole place pool wall or wall are not made consolidation process; Second kind of processing scheme: water string requires to make, install according to existing national standard atlas, and hole place pool wall or wall adopt the additional bar consolidation process is set.
The shortcoming of first kind of processing scheme existence has following 2 points: the first, steel concrete pool wall or body of wall are strengthened after punching, and there is potential safety hazard; Second, requiring the wing ring of the water string of making according to existing national standard atlas is the single-blade ring, in addition national standard atlas require sleeve pipe should be before wall or pool wall concreting installation in position, and this method of burying water string after punching on existing steel concrete pool wall or the body of wall again underground can only be by the space between grouting material grouting filling hole and sleeve pipe after sleeve pipe is in place, because grouting is not easy to irritate closely knit, causes leakage problems in various degree easily.
The shortcoming that existing second kind of processing scheme exists has following 2 points: first, need around hole, to add stiffener according to code requirement, stiffener need satisfy the anchorage length requirement, so exceed the long size of hole edge, if will imbed reinforcing bar digs concrete area and will increase the engineering quantity of cutting and strengthening construction much larger than bore hole size; The second, with first kind of scheme, there is leakage problems in various degree.
The utility model content
First purpose of the present utility model is to provide a kind of reinforcing and anti-leakage structure that punches on existing steel concrete wall.
Second purpose of the present utility model is to provide a kind of ruggedized construction that punches on existing steel concrete wall.
First purpose of the present utility model is implemented by following technical scheme, a kind of reinforcing and anti-leakage structure that on existing steel concrete wall, punches, it is by sleeve pipe, the inner wing ring, the outer wing ring, the body of wall reinforcing bar, reinforced concrete wall and grouting material are formed, described inner wing ring and described outer wing ring are enclosed within described sleeve outer wall two ends respectively, and with described sleeve outer wall seal welding, described inner wing ring and described outer wing ring are welded to connect with described body of wall reinforcing bar respectively, irritate real sealing by described grouting material between described reinforced concrete wall and the described sleeve outer wall.
Second purpose of the present utility model implemented by following technical scheme, a kind of ruggedized construction that on existing steel concrete wall, punches, it comprises inner wing ring, outer wing ring, body of wall reinforcing bar and reinforced concrete wall, described inner wing ring and described outer wing ring laterally place described reinforced concrete wall medial and lateral along described reinforced concrete wall, and be welded to connect with described body of wall reinforcing bar respectively, between described inner wing ring and the described outer wing ring and both sides are the grouting material to described reinforced concrete wall, and described grouting material is provided with through hole along described inner wing ring and described outer wing ring center line.
In the processing of antiseep problem, characteristics of the present utility model are that sleeve pipe changes the double-vane eyelet thimble into by existing single-blade eyelet thimble, owing to increased a wing ring, be equivalent to increase waterproof measure one, another wing ring can also play waterproof action under the situation of a wing ring waterproof failure.
In the processing of the problem of reinforcing, characteristics of the present utility model are two wing rings are separately positioned on the sleeve pipe corresponding to the two-layer reinforcing bar position in the outside in the reinforced concrete wall, and the reinforcing bar that the hole place is blocked is welded on respectively on the wing ring of relevant position, wing ring can play to connect and block action of steel bars like this, and the intensity of wing ring itself also can play the booster action to hole simultaneously.
Advantage of the present utility model is, 1, the antiseep of sleeve pipe changes double-vane ring antiseep into by existing single-blade ring antiseep, can play good antiseep effect; 2, be welded on the double-vane ring owing to blocking reinforcing bar, make the wing ring steel plate of double-vane eyelet thimble play the hole booster action; 3, adopt the double-vane eyelet thimble can make the size that punches be slightly larger than the size of sleeve pipe, reduced because the high problem of constructional difficulties, cost that punches and cause too greatly to the punch processing method of poling of existing steel concrete pool wall or wall.

The specific embodiment
Embodiment 1: a kind of reinforcing and anti-leakage structure that punches on existing steel concrete wall, it is by sleeve pipe 2, inner wing ring 3, outer wing ring 5, body of wall reinforcing bar 4, reinforced concrete wall 1 and grouting material 6 are formed, inner wing ring 3 and outer wing ring 5 are enclosed within sleeve pipe 2 outer wall two ends respectively, and with sleeve pipe 2 outer wall seal weldings, inner wing ring 3 and outer wing ring 5 are welded to connect with body of wall reinforcing bar 4 respectively, irritate real sealing by grouting material 6 between reinforced concrete wall 1 and sleeve pipe 2 outer walls.
Embodiment 2: do not have leakage problems when punching on existing steel concrete pool wall or wall, when only considering that the hole place strengthens, can remove sleeve pipe and only stay the reinforcement that the double-vane ring is used for the hole place.A kind of ruggedized construction that on existing steel concrete wall, punches, it comprises inner wing ring 3, outer wing ring 5, body of wall reinforcing bar 4 and reinforced concrete wall 1, inner wing ring 3 and outer wing ring 5 laterally place reinforced concrete wall 1 medial and lateral along reinforced concrete wall 1, and be welded to connect with body of wall reinforcing bar 4 respectively, between inner wing ring 3 and the outer wing ring 5 and both sides are grouting material 6 to reinforced concrete wall 1, and grouting material 6 is provided with through hole 7 along inner wing ring 3 and outer wing ring 5 center lines.
