Abstract
One is exempted to search formula built-in pipe, comprises built-in pipe, is fixed with in mouth of pipe one end of built-in pipe the elastic component be made up of steel wire or steel tendon, on the inwall that elastic component is welded on built-in pipe or outer wall.The present invention adopts elastic wire to combine with built-in pipe; solve the drawback of the pre-buried method of conventional steel pipe dexterously; improve the built-in pipe mouth of pipe and find out rate; reduce and repeat perforate to the destruction of building surface and internal construction; meet built-in fitting in the requirement of watering protective layer thickness in building body; reduce difficulty of construction and construction cost, considerably improve efficiency of construction accelerating construction progress, achieve good economic benefit.
Description
Technical field
The present invention relates to and a kind ofly bury assembly underground what water built-in pipe device in building body.
Background technology
The pre-buried mode of conventional concreting grout hole position built-in pipe mostly is that steel pipe is firm to direct reinforcement welding by design Kong Weikong; again the two ends mouth of pipe stopper of pipe laying or cotton yarn are closed; then in template, mark is carried out with red paint, need by one end of built-in pipe and template proximate (not meeting built-in fitting in the requirement of watering protective layer thickness in building body) during installation.This mode produces displacement because causing between template and built-in pipe in concrete placings process, the built-in pipe mouth of pipe or paint marks cannot be directly found after Many times form removal, built-in pipe finds out rate lower (being generally about 85%), particularly vertical shaft taper template system continuously sliding build between template and built-in pipe displacement larger, the rate of finding out of built-in pipe is extremely low (being generally about 10%), cause follow-up drilling construction difficulty large, often repeatedly perforate just can avoid the steel mesh reinforcement pore-creating buried underground, normal destruction waters the structure of building body and reinforcing bar, and high material consumption efficiency of construction is low, inapplicable in steel bar concrete pre-embedment grouting pipe.
Summary of the invention
Technical problem to be solved by this invention is to provide one and exempts to search formula built-in pipe; use this built-in pipe can improve the built-in pipe mouth of pipe and find out rate; reduce and repeat perforate to the destruction of building surface and internal construction; meet built-in fitting in the requirement of watering protective layer thickness in building body; reduce difficulty of construction and construction cost, significantly improve efficiency of construction.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: one is exempted to search formula built-in pipe, comprises built-in pipe, is fixed with elastic component in one end of the mouth of pipe of built-in pipe.
Described elastic component is steel wire or steel tendon elastomeric material.
On the inwall that described elastic component is welded on built-in pipe or outer wall.
Described elastic component is by fixing one end being connected to built-in pipe.
The open height of described fixing card is identical with the wall thickness of built-in pipe.
By exceeding the steel wire bent of built-in pipe opening part by being pressed in template, make it keep prestressing force elasticity, in casting process, the elastic component of built-in pipe is all the time by being pressed in template under the effect of elastic force, and steel wire head is exposed in form removal after-pouring surface.
One is exempted to search formula built-in pipe, comprises built-in pipe, and be provided with piston in built-in pipe one end, piston matches with spring, and spring is arranged in built-in pipe by spring supporting ring.
The mouth of pipe that the present invention achieves 99% in the application of pressure pipeline vertical shaft section taper climbing forms continuous placing finds out rate; substantially avoided repetition perforate and built-in fitting is met in the requirement of watering protective layer thickness in building body to the destruction of building surface and internal construction; reduce difficulty of construction and construction cost; considerably improve efficiency of construction and accelerate construction speed, achieve good economic benefit.

Detailed description of the invention
Concrete structure of the present invention is as follows:
As shown in Figure 1, one is exempted to search formula built-in pipe, and elastic component 2 is welded on the inwall of built-in pipe 1.
As shown in Figure 2, one is exempted to search formula built-in pipe, and elastic component 2 is welded on the outer wall of built-in pipe 1.
As shown in Figure 3, one is exempted to search formula built-in pipe, and elastic component 2 is connected to one end of built-in pipe 1 by fixing card 8, and the open height of fixing card 3 is identical with the wall thickness of built-in pipe 1.
In above-described embodiment, elastic component 2 is steel wire or steel tendon elastomeric material.
As shown in Figure 4, one is exempted to search formula built-in pipe, comprises built-in pipe 1, it is characterized in that: be provided with piston 3 in built-in pipe 1 one end, piston 3 matches with spring 5, and spring 5 is arranged in built-in pipe 1 by spring supporting ring 4.
Operating principle of the present invention is as follows:
Exempt from the formula of searching pre-buried tube method specific operation process as follows:
1, the length of elastic component 2 is chosen according to embedded pipe orifice and the possible maximum displacement+20cm of template 6.
2, built-in pipe 1 and elastic component 2 are made by Fig. 1-3, if shaping elastic component 2 is pacified by snap fit
Be contained on built-in pipe 1, as required built-in pipe 2 two ends closed.
3, settle built-in pipe 2 according to design pipe and be fixed with built-in pipe support 7 that (built-in pipe support 7 can adopt the structure that waters in building body or make separately according to physical condition, as long as maintenance firmly meets when building indeformable), require during installation that by the distance of one end of built-in pipe welding wire distance template 6 be 5cm, to the steel wire bent of steel pipe opening part be exceeded by being pressed in template 6, make it keep prestressing force elasticity, in casting process, the elastic component 2 of built-in pipe can all the time by being pressed in template 6 under the effect of elastic force.
4, the position that can judge built-in pipe after building body reaches solidifying phase form removal according to the steel wire head of building surface exposure is fast and accurately watered.
5, when adopting the piston shown in Fig. 4 during structure, can according to the position of the position judgment built-in pipe 1 of piston 3.
