Description
Technical field:
The present invention relates to prestressed reinforced concrete resistance to plucking hollow pile and attaching method thereof, particularly with prestressed reinforced concrete resistance to plucking hollow pile of syndeton and attaching method thereof.
Background technology:
Existing prestressed reinforced concrete resistance to plucking hollow pile syndeton comprises the circular end plate that is fixedly installed on resistance to plucking pile crown two ends, is arranged with a plurality of arc mechanical connection cards outside two circular end plate of resistance to plucking pile crown joint.The method of attachment of existing prestressed reinforced concrete resistance to plucking hollow pile is connected on the circular end plate for described arc mechanical connection cartoon is crossed a plurality of screw, and two uplift piles link together thereby make up and down.Though this technology has solved two uplift pile connectivity problems up and down, but because it has added arc mechanical connection card, so the two ends diameter dimension of the pile body of prestressed reinforced concrete resistance to plucking hollow pile must be reduced, the diameter dimension that is less than or equal to the pile body of prestressed reinforced concrete resistance to plucking hollow pile with the peripheral dimension that guarantees arc mechanical connection card, influenced the bulk strength of prestressed reinforced concrete resistance to plucking hollow pile, in addition, this technology is also because manufacturing cost is too high, joint efficiency is low, is difficult to promote the use of in the pile foundation industry.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, two prestressed reinforced concrete hollow piles linked together effectively about a kind of can making was provided, easy to connect, simple to operate, prestressed reinforced concrete resistance to plucking hollow pile of the band syndeton that cost is inefficient high and attaching method thereof.
Solution of the present invention: the prestressed reinforced concrete resistance to plucking hollow pile of band syndeton, contain hollow pile body, end plate, end plate is arranged on the two ends of hollow pile body, the periphery of the end plate upper edge through hole of hollow pile body one end is provided with hook-shaped connector, the periphery of the end plate upper edge through hole of the hollow pile body other end is provided with groove, there is through hole at the end plate middle part, the diameter of end plate middle part through hole is less than the diameter of the cylindricality through hole of hollow pile body, be convenient to hook-shaped connector and can pass groove, and realize being connected with the effective of end plate of band groove.
The periphery of the end plate upper edge through hole of hollow pile body one end is provided with at least two hook-shaped connectors, the periphery of the end plate upper edge through hole of the hollow pile body other end is provided with and the corresponding groove of hook-shaped connector, an end and any hollow pile body of end plate of being convenient to the connector with hook of any hollow pile body has the end interlock mutually of the end plate of groove, realizes the efficient and convenient connection between two hollow pile bodies.
Hook-shaped connector is made up of coupler body and gib head, gib head is towards the hole wall of the cylindricality through hole at hollow pile body middle part, the gib head inboard of hook-shaped connector and the distance between the end plate are convenient to the interlock between hook-shaped connector and the end plate greater than the thickness of the end plate of the hollow pile body other end.
Hook-shaped connector on the end plate and end plate upper groove are all along the peripheral uniform of the through hole of end plate or be symmetrically distributed.
The coupler body of hook-shaped connector is designed to the staight shank structure, and the hole wall of the through hole on coupler body and the end plate is welded to connect.
The coupler body of hook-shaped connector is designed to curved handle structure, the curved shank portion of coupler body directly is stuck on the end plate, at this moment, the curved shank portion of coupler body only needs spot welding to get final product with being connected of end plate, because the axial tension that hollow pile body bore directly has been delivered on the medial surface of end plate by the curved shank portion of coupler body, and no longer be the axial tension that bear the junction of through hole hole wall on the end plate and coupler body, bonding strength is higher, better reliability.
The end plate inboard is provided with reinforcing rib, has improved the stretching resistance of end plate on the one hand, has also played the position-limiting action to the gib head of hook-shaped connector on the other hand.
The method of attachment of the prestressed reinforced concrete hollow pile of band syndeton, end plate one end that has groove on one end of the end plate of connector with hook on the last hollow pile body and the hollow pile body is down docked, after going up gib head on the hollow pile body end plate and passing down groove on the end plate that hollow pile body has groove, go up hollow pile body along the circumference clockwise direction of last hollow pile body or rotation counterclockwise, make the gib head of the hook-shaped connector of hollow pile body one end enter down the inboard that hollow pile body has the end plate of groove, thereby the end plate of two hollow pile bodies is interlocked, and hollow pile body and following hollow pile body tightly links together in the realization.
After going up gib head on the hollow pile body and passing down groove on the end plate that has groove on the hollow pile body, go up hollow pile body along the circumference clockwise direction of last hollow pile body or rotation counterclockwise, making the gib head of the hook-shaped connector of hollow pile body one end enter down the inboard that hollow pile body has the end plate of groove promptly stops operating when gib head touches down the reinforcing rib that hollow pile body has on the inboard of end plate of groove, thereby the end plate of two hollow pile bodies is interlocked, and hollow pile body and following hollow pile body tightly links together in the realization.
Advantage of the present invention is: can make two uplift piles up and down realize effectively connecting, resistance to plucking is effective, and is simple to operate, and cost is low, the efficient height.
