Abstract
The invention relates to a find-free embedded pipe. The find-free embedded pipe comprises an embedded pipe, wherein a resilient piece which is made of a steel wire or a steel bundle is fixed on a pipe orifice end of the embedded pipe, and the resilient piece is welded on the inner wall or the outer wall of the embedded pipe. The resilient steel wire is combined with the embedded pipe, so that the weaknesses of the conventional steel pipe embedding method can be ingeniously solved, the find-out rate of the embedding pipe orifice can be improved, the damage of the repeat perforation on the surface and the internal structure of a casting body can be reduced, the requirement of the embedded piece on the thickness of a protection layer in the casting body can be met, the construction difficulty and the construction cost can be reduced, the construction efficiency can be remarkably improved, the construction progress can be accelerated, and the economic benefit is good.
Description
Technical field
The present invention relates to a kind of in watering building body built-in pipe device bury assembly underground.
Background technology
The pre-buried mode of conventional concreting grout hole position built-in pipe mostly is steel pipe by designing Kong Weikong to the direct reinforcing bar firm welding of using; again by stopper or cotton yarn sealing for the two ends mouth of pipe of pipe laying; then with red paint, in template, carry out mark, need be by one end of built-in pipe and template proximate (not meeting the requirement of built-in fitting protective layer thickness in watering building body) during installation.This mode is because causing between template and built-in pipe and produce displacement in concrete casting process, in the time of mostly, after form removal, cannot directly find the built-in pipe mouth of pipe or paint mark, built-in pipe is found out rate lower (being generally about 85%), particularly at vertical shaft taper template system, continuously sliding to build between middle template and built-in pipe displacement larger, the rate of finding out extremely low (being generally about 10%) of built-in pipe, cause follow-up drilling construction difficulty large, the steel mesh reinforcement pore-creating that often repeatedly perforate just can be avoided burying underground, the normal structure of watering building body and reinforcing bar of destroying, 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 a kind of formula built-in pipe of exempting to search; use this built-in pipe can improve the built-in pipe mouth of pipe and find out rate; reduce and repeat perforate to building the destruction of surface and internal construction; meet the requirement of built-in fitting protective layer thickness in watering 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: a kind ofly exempt to search formula built-in pipe, comprise built-in pipe, the elastic component that is fixed with in mouth of pipe one end of built-in pipe.
Described elastic component is steel wire or steel tendon elastomeric material.
Described elastic component is welded on the inwall or outer wall of built-in pipe.
Described elastic component is connected to one end of built-in pipe by fixed card.
The open height of described fixed card is identical with the wall thickness of built-in pipe.
Exempt to search a formula built-in pipe, comprise built-in pipe, in built-in pipe one end, be provided with piston, piston matches with spring, and spring is arranged in built-in pipe by spring supporting ring.
The present invention has realized 99% the mouth of pipe and has found out rate in pressure pipeline vertical shaft section taper climbing forms continuous placing application; substantially avoid repeating perforate and to building the destruction of surface and internal construction, met the requirement of built-in fitting protective layer thickness in watering building body; reduce difficulty of construction and construction cost; improve significantly efficiency of construction and accelerated construction speed, obtained good economic benefit.

The specific embodiment
Concrete structure of the present invention is as follows:
As shown in Figure 1, a kind ofly exempt to search formula built-in pipe, elastic component 2 is welded on the inwall of built-in pipe 1.
As shown in Figure 2, a kind ofly exempt to search formula built-in pipe, elastic component 2 is welded on the outer wall of built-in pipe 1.
As shown in Figure 3, a kind ofly exempt to search formula built-in pipe, elastic component 2 is connected to one end of built-in pipe 1 by fixed card 8, and the open height of fixed 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, a kind ofly exempt to search formula built-in pipe, comprise built-in pipe 1, it is characterized in that: in built-in pipe 1 one end, be provided with piston 3, 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 to search formula built-in pipe method specific operation process as follows:
1, according to embedded pipe orifice and the possible maximum displacement+20cm of template 6, choose the length of elastic component 2.
2, built-in pipe 1 and elastic component 2 are made by Fig. 1-3, if snap fit is by the elastic component of moulding 2 peaces
Be contained on built-in pipe 1, as required built-in pipe 2 two ends sealed.
3, according to design pipe laying position, settle built-in pipe 2 and with built-in pipe support 7, be fixed that (built-in pipe support 7 can adopt the structure watering in building body or make separately according to physical condition, as long as indeformable while keeping firm satisfied building), during installation, requiring one end of built-in pipe welding wire is 5cm apart from the distance of template 6, to exceed steel pipe opening steel wire bending partly by being pressed in template 6, make it keep prestressing force elasticity, in casting process, the elastic component 2 of built-in pipe can be all the time by being pressed in template 6 under the effect of elastic force.
4, water after building body reaches solidifying phase form removal and can judge fast and accurately according to the steel wire head of building surface exposure the position of built-in pipe.
5, when adopt shown in Fig. 4 piston time during structure, can be according to the position of the position judgment built-in pipe 1 of piston 3.
