Abstract
An embedded pipe free of searching comprises an embedded pipe body, an elastic component made of steel wires or steel wire bundles is fixed at the pipe orifice end of the embedded pipe body, and the elastic component is welded on the inner wall or the outer wall of the embedded pipe body. According to the embedded pipe free of searching, the elastic component made of the steel wires or the steel wire bundles is combined with the embedded pipe body, defects of a common steel pipe embedding method are ingeniously overcome, a finding-out rate of an orifice of the embedded pipe body is improved, damage to the surface and the internal structure of a pouring body caused by repeated pore opening is reduced, requirements on the thickness of a protective layer of the embedded pipe in the pouring body are met, construction difficulty and construction cost are lowered, construction efficiency is notably improved, construction progress is accelerated, and good economical benefits are obtained.
Description
Technical field
The utility model relate to a kind of in building body the built-in pipe device bury assembly underground.
Background technology
The pre-buried mode of concreting grout hole position built-in pipe commonly used mostly is steel pipe by designing Kong Weikong to the direct reinforcing bar firm welding of using; the two ends mouth of pipe with pipe laying seals with stopper or cotton yarn again; then carry out mark with red paint in template, need an end and template proximate (not satisfying the requirement of built-in fitting protective layer thickness in building body) with built-in pipe during installation.This mode produces displacement because causing between template and the built-in pipe in the concrete casting process, can't directly find the built-in pipe mouth of pipe or paint mark in the time of mostly after the form removal, built-in pipe is found out rate lower (generally being about 85%), particularly continuously sliding to build between middle template and the built-in pipe displacement larger at vertical shaft taper template system, the rate of finding out of built-in pipe extremely low (generally being about 10%), cause follow-up drilling construction difficulty large, the often repeatedly perforate steel mesh reinforcement pore-creating that just can avoid burying underground, the normal structure of building body and reinforcing bar of destroying, and the 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 in the utility model provides 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; satisfy the requirement of built-in fitting 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 scheme that the utility model adopts is: a kind ofly exempt to search the formula built-in pipe, comprise built-in pipe, at the elastic component that is fixed with of the 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 an 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.
A kind ofly exempt to search the formula built-in pipe, comprise built-in pipe, be provided with piston at built-in pipe one end, piston matches with spring, and spring is installed in the built-in pipe by the spring supporting ring.
The utility model has realized that in pressure pipeline vertical shaft section taper climbing forms continuous placing is used 99% the mouth of pipe finds out rate; substantially avoided repeating built-in fitting protective layer thickness in building body has been satisfied in perforate to the destruction of building surface and internal construction requirement; 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 utility model is as follows:
As shown in Figure 1, a kind ofly exempt to search the 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 the 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 the formula built-in pipe, elastic component 2 is connected to an 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 the formula built-in pipe, comprise built-in pipe 1, it is characterized in that: be provided with piston 3 at built-in pipe 1 one ends, piston 3 matches with spring 5, and spring 5 is installed in the built-in pipe 1 by spring supporting ring 4.
Operating principle of the present utility model is as follows:
Exempt to search formula built-in pipe method specific operation process as follows:
1, chooses the length of elastic component 2 according to embedded pipe orifice and template 6 possible maximum displacement+20cm.
2, built-in pipe 1 and elastic component 2 are made by Fig. 1-3, if snap fit is with elastic component 2 peaces of moulding
Be contained on the built-in pipe 1 and get final product, as required built-in pipe 2 two ends are sealed.
3, settle built-in pipe 2 according to design pipe laying position and be fixed with built-in pipe support 7 that (built-in pipe support 7 can adopt the structure of building in the body or make separately according to physical condition, as long as indeformable when keeping firm satisfied building), requiring an end of built-in pipe welding wire during installation is 5cm apart from the distance of template 6, to exceed the steel wire bending of steel pipe opening part by being pressed on the template 6, make it keep prestressing force elasticity, the elastic component 2 of built-in pipe is being understood all the time by being pressed on the template 6 under the effect of elastic force in the casting process.
4, build body and reach the position that to judge fast and accurately built-in pipe after the solidifying phase form removal according to the steel wire head of building the surface exposure.
5, when adopting piston shown in Figure 4 during structure, can be according to the position of the position judgment built-in pipe 1 of piston 3.
