Abstract
Disclosed is a unidirectional air outlet pipe with a function of self closing. The conventional grouting method always utilizes embedded grout pipe to actuate pressure grouting, air outlet pipes are needed to be sealed at the end of grouting, slurry loss is easy to be caused by action of grouting pressure and complexity of sealing processes, thereby reducing reliably of steel reinforcement connection. The unidirectional air outlet pipe with a function of self closing comprises a tubular air outlet pipe body (1) and an air sucking pipe (3), two ends of the tubular air outlet pipe body are opened, a unidirectional opening valve (2) is arranged inside, and the air sucking pipe is also a tube with two opening ends. The unidirectional air outlet pipe is used for grouting connection of steel reinforcements among prefabricated concrete structural components.
Description
Technical field:
The utility model relates to anchoring of a kind of building prefabrication concrete structure member reinforcing bar and the grouting equipment that overlap joint is connected, and is specifically related to a kind of unidirectional escape pipe with self-closing function.
Background technology:
In precast concrete, preformed hole grouting bar splicing method of attachment is adopted in the anchor connection of reinforcing bar more, but traditional grouting method adopts the pre-embedment grouting pipe pressure grouting more, when finishing, grouting need carry out shutoff to escape pipe, because the effect of grouting pressure and the complexity of shutoff process, very easily cause the loss of slurries, thereby reduced the reliability that reinforcing bar connects.Therefore need a kind of unidirectional escape pipe, avoid the complexity of grouting construction, improve the degree of reliability of grouting with self-closing function.
Summary of the invention:
The purpose of this utility model provides a kind of unidirectional escape pipe with self-closing function, makes filling process simple more, reliable.
Above-mentioned purpose realizes by following technical scheme:
Have the unidirectional escape pipe of self-closing function, its composition comprises: tubulose escape pipe body and air entraining pipe, and described tubulose escape pipe body is the both ends open tubulose, and inside has unidirectional unlatching valve, and described air entraining pipe is the both ends open tubulose.
Described unidirectional escape pipe with self-closing function, described valve and described tubulose escape pipe body are that one processes.
Described unidirectional escape pipe with self-closing function, described valve is 3, is 120 along described tubulose escape pipe body interior and spends distribution, and unified towards the inclination in the other direction of giving vent to anger, its nature is a closure state, is normally closed one way valve.
Described unidirectional escape pipe with self-closing function, the external diameter of described air entraining pipe is less than the internal diameter of described tubulose escape pipe body.
Beneficial effect of the present invention:
1. the unidirectional escape pipe with self-closing function that the present invention realized is simple to operate when grouting construction, and work progress does not need complicated mechanical equipment and facility, does not also need power consumption.Grouting relies on the elasticity valve closure of unidirectional escape pipe inside when finishing, thereby realizes the auto-closing shutoff, so filling process is simple, dependable performance, and characteristics are built in the construction that is suitable for the housing industrialization precast concrete again.
2. simple, the construction quality of this product processing technique is easy to guarantee that the job site be dried operation substantially, has fully avoided all disadvantages of conventional grout mode.The building course environmental protection and energy saving, reduce cost, save construction fund.
Description of drawings:
Accompanying drawing 1 is the structural representation in this product filling process.
Accompanying drawing 2 is A-A sectional drawings of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Have the unidirectional escape pipe of self-closing function, its composition comprises: tubulose escape pipe body 1 and air entraining pipe 3, and described tubulose escape pipe body is the both ends open tubulose, and inside has unidirectional unlatching valve 2, and described air entraining pipe is the both ends open tubulose.
The above-mentioned unidirectional escape pipe with self-closing function, described valve and described tubulose escape pipe body are that one processes.
Embodiment 2:
Above-mentioned unidirectional escape pipe with self-closing function, described valve is 3, is 120 along described tubulose escape pipe body interior and spends distribution, and unified towards the inclination in the other direction of giving vent to anger, its nature is a closure state, is normally closed one way valve.
Embodiment 3:
The above-mentioned unidirectional escape pipe with self-closing function, the external diameter of described air entraining pipe is less than the internal diameter of described tubulose escape pipe body.
Insert air entraining pipe earlier in when grouting and strut valve, it is given vent to anger in filling process, when grouting finishes, extract air entraining pipe, but then valve itself elastic reaction and grouting pressure under auto-closing.
Claims (5)
1. unidirectional escape pipe with self-closing function, its composition comprises: tubulose escape pipe body and air entraining pipe, it is characterized in that: described tubulose escape pipe body is the both ends open tubulose, and inside has unidirectional unlatching valve, and described air entraining pipe is the both ends open tubulose.
