Abstract
The utility model relates to a crane beam curved prestressed combined corrugated tube. A problem of prestressed channel blocking is usually caused during the construction of a crane beam curved prestressed combined corrugated tube. In order to solve the problem, the crane beam curved prestressed combined corrugated tube comprises a corrugated tube and is characterized in that a plastic pipe is arranged in the corrugated tube; the two ends of the plastic pipe expose out of the corrugated tube; the external diameter of the plastic pipe is smaller than the internal diameter of the corrugated tube by 10-15 mm. Owing to the design, when concrete is made, for example, a vibration rod vibrates and breaks the corrugated tube, grout flows into the corrugated tube and the plastic pipe is pumped, a prestressed channel is prevented from being blocked, and the situation that a prestressed steel twisted line cannot penetrate through the prestressed channel is avoided. The crane beam curved prestressed combined corrugated tube is simple to operate and convenient to use during the construction of the crane bean curved prestressed combined corrugated tube, facilitates the acceleration of the period of the construction, creates good conditions for the next step of prestressed tension, and is sutiable for use of construction of a curved prestressed crane beam.
Description
Technical field
The utility model relates to a kind of crane girder curved prestressing force combination bellows.
Background technology
The anti-blocking conventional approach of crane girder curved prestressing force bellows is by the sealant tape shutoff of the jointing of bellows both sides.But when site operation, burn broken bellows when reinforcement installation is welded, while beating cement concrete, shake the brokenly processing method of the phenomenons such as bellows of vibrating head is inconsiderate, has not only caused economic loss, has also affected duration progress.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of crane girder curved prestressing force combination bellows is provided.
For solving the problems of the technologies described above, this crane girder curved prestressing force combination bellows, comprises bellows, it is characterized in that: in described bellows, be provided with a plastic pipe, bellows is exposed at plastic pipe two ends, and its overall diameter is than the little 10～15mm of bellows interior diameter.So design, in the time beating cement concrete, as the vibrating head bellows that shakes brokenly, cement wash inflow bellows interior, can twitch plastic pipe, has prevented prestressed pore passage obstruction, has avoided prestress wire cannot penetrate in prestressed pore passage.
As optimization, described bellows one end is provided with shutoff sealant tape, and the other end is provided with sleeve pipe.So design, can avoid cement wash to enter prestress bellows from prestress bellows two ends.
Use this crane girder curved prestressing force combination bellows to carry out crane girder curved prestressing force bellows constructing operation simple, easy to use, and contribute to accelerate duration progress, for next step prestressed stretch-draw has been created good condition, be applicable to the construction of curved prestressing force crane girder and use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this crane girder curved prestressing force combination bellows is described further:
Fig. 1 is the use state cross-sectional view (dissecing along prestressed pore passage line of centers) of this crane girder curved prestressing force combination bellows.
In figure, 1 is that bellows, 2 is that plastic pipe, 3 is that shutoff sealant tape, 4 is that sleeve pipe, 5 is crane girder.
The specific embodiment
Embodiment one: as shown in Figure 1, this crane girder curved prestressing force combination bellows comprises bellows 1, is provided with a plastic pipe 2 in described bellows 1, and expose outside bellows 1 at plastic pipe 2 two ends, and its overall diameter is than the little 10～15mm of bellows 1 interior diameter.Described bellows 1 one end is provided with shutoff sealant tape 3, and the other end is provided with sleeve pipe 4.
Claims (2)
1. a crane girder curved prestressing force combination bellows, comprises bellows, it is characterized in that: in described bellows, be provided with a plastic pipe, expose outside bellows at plastic pipe two ends, and its overall diameter is than the little 10～15mm of bellows interior diameter.
2. crane girder curved prestressing force combination bellows as claimed in claim 1, is characterized in that: described bellows one end is provided with shutoff sealant tape, and the other end is provided with sleeve pipe.
