Abstract
The utility model discloses a circular plastic tubing of bamboo -shaped prestressing force, circular plastic tubing of bamboo -shaped prestressing force is connected gradually by a plurality of tube couplings that the structure is the same to constitute, every tube coupling all includes: a big round tube that connects gradually, a little round tube, a well round tube and a little round tube, the shape of big round tube cross section, well round tube cross section and small circle venturi tube cross section is the round tube, the wall thickness degree of round tube is the same, the dimensions of big round tube cross section, well round tube cross section and small circle venturi tube cross section decreases progressively in proper order. The utility model discloses beneficial effect is: be fit for the construction of vacuum mud jacking post stretching prestressed concrete, guarantee prestressed duct filling compactness and plumpness, the anti -destructive is strong, increase with concrete area of contact, be favorable to the reliability of prestress wire grout back and the transmission of concrete member power, be used for pre -buriedly at the less component of thickness.
Description
Technical field
The utility model relates to plastic pipe, particularly be a kind of Bamboo-shaped prestressing force round plastic pipe.
Background technology
In recent years along with the development of building trade, prestressed concrete is promoted gradually, and compared with conventional steel bar concrete, it is high that prestressed concrete has intensity, save the advantages such as material, now advanced technology is vacuum grouting post stressed concrete technology.Its feature is first concreting, pre-plugged helical metal pipe or plastic pipe in concrete, after concrete reaches some strength, tractive prestress wire in pre-buried helical metal pipe or plastic pipe again, then with ground tackle, prestress wire is fixed on component, finally vacuumizes at pipeline one end vacuum pump, make it produce the vacuum of-0.1Mpa, with grout pump, special cement is poured into from the pipeline other end again, until be full of pipeline.These spiral metal tubes or plastic pipe not only need for prestress wire provides protective barrier, also need higher sealing to ensure the quality of vacuum grouting.
Built-in pipe now for prestressed reinforced concrete construction is commonly helical form round metal tube or round plastic pipe, this helical form round metal tube or plastic pipe limit due to processing technology, can not the higher material of working strength or larger wall thickness, so in construction, be easy to be smashed to pieces by vibrating head or step on split.And due to helical form round metal tube outer rim having continuous print helical form muscle always, so more loaded down with trivial details in the encapsulation process of round tube junction, be easy to the phenomenon leaked air, reduce compactness and the plumpness of prestressed pore passage grouting.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of intensity high, seal easy a kind of Bamboo-shaped prestressing force round plastic pipe reliably.
The technical scheme solved the problems of the technologies described above is: a kind of Bamboo-shaped prestressing force round plastic pipe, described Bamboo-shaped prestressing force round plastic pipe is connected and composed successively by multiple tube couplings that structure is identical, and described each tube coupling includes: the large round tube connected successively, small circular pipe, a middle round tube and a small circular pipe; The shape of described large round tube cross section, middle round tube cross section and small circular pipe cross section is round tube, and the pipe thickness of described round tube is identical; The overall size of described large round tube cross section, middle round tube cross section and small circular pipe cross section is successively decreased successively.
Preferred version is: a described large round tube, small circular pipe, excessively connect with circular arc between a middle round tube and a small circular pipe.
Preferred version is: the axial width of the axial width of described large round tube, the axial width of middle round tube and small circular pipe successively decreases successively.
Preferred version is: the two ends of described Bamboo-shaped prestressing force round plastic pipe is small circular pipe, and the width of the small circular pipe of two ends is slightly longer than the width of the small circular pipe in described tube coupling.
The beneficial effects of the utility model are:
1, the utility model adopts Bamboo-shaped plastic pipe to replace traditional spiral pipe, seals easier, reliable.Be applicable to very much advanced vacuum grouting post stressed concrete construction, ensure compactness and the plumpness of prestressed pore passage grouting.
2, the utility model can the high material of selection intensity, and can make the prestressed plastic pipe of different wall specification, and use safer, anti-destructive is stronger.
3, the utility model adopts the structure that large round tube and middle round tube replace successively, add the contact area of prestressed plastic pipe and concrete component, laminating is stronger, is conducive to the reliability that presstressed reinforcing steel in prestressed plastic pipe is in the milk afterwards and concrete component power is transmitted.

1: middle round tube; 2: large round tube; 3: small circular pipe; 4: prestressing force round plastic pipe.
Detailed description of the invention
As shown in the figure, the utility model provides a kind of Bamboo-shaped prestressing force round plastic pipe, described Bamboo-shaped prestressing force round plastic pipe is connected and composed successively by multiple tube couplings that structure is identical, and described each tube coupling includes: the large round tube connected successively, small circular pipe, a middle round tube and a small circular pipe; The shape of described large round tube cross section, middle round tube cross section and small circular pipe cross section is round tube, and the pipe thickness of described round tube is identical; The overall size of described large round tube cross section, middle round tube cross section and small circular pipe cross section is successively decreased successively.
A described large round tube, small circular pipe, excessively to connect with circular arc between a middle round tube and a small circular pipe.
The axial width of the axial width of described large round tube, the axial width of middle round tube and small circular pipe successively decreases successively.
The two ends of described Bamboo-shaped prestressing force round plastic pipe is small circular pipe, and the width of the small circular pipe of two ends is slightly longer than the width of the small circular pipe in described tube coupling.
In particular, Bamboo-shaped prestressing force round plastic pipe 4 is integrated by mould compression molding, and wall thickness is everywhere equal, and can make the Bamboo-shaped prestressing force round plastic pipe of different-thickness according to requirement of strength.Its material can be high-strength polyvinyl chloride, or other highstrenghtpiston.
Because the large round tube 2 of Bamboo-shaped prestressing force round plastic pipe 4 is separate, when doing encapsulation process, only need to utilize an other round tube joint component, large round tube 2 on adjacent Bamboo-shaped prestressing force round plastic pipe 4 is sealed respectively, two Bamboo-shaped prestressing force round plastic pipes 4 can be linked into an integrated entity.
In use, first concreting, in concrete, pre-plugged Bamboo-shaped prestressing force round plastic pipe 4, utilizes round tube joint or sweat soldering, adjacent two Bamboo-shaped prestressing force round plastic pipes 4 is fixedly connected to form one.And then carry out follow-up implementing dragline operation to the prestress wire in Bamboo-shaped prestressing force round plastic pipe 4.
