Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a concrete pipe pile head connection structure. Background Technology

[0002] Concrete pipe piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete). They have advantages such as saving timber and steel, durability, and low cost, and have been widely used in the foundation engineering of hydraulic structures, industrial buildings, civil buildings and bridges. They are also often used for anti-sliding or water-proofing of slopes and foundation pits.

[0003] In the existing technology, concrete pipe piles are buried in pile pits. Due to the large depth of the pile pits and the limited length of the concrete pipe piles, there is a phenomenon that two or more concrete pipe piles need to be stacked in the same pile pit. Then, steel bars welded together are used to penetrate the stacked concrete pipe piles to achieve the correction and limiting of the stacked concrete pipe piles.

[0004] However, when using reinforced concrete pipe piles with stacked steel bars, there is a large consumption of steel bars, and the construction work of hoisting the steel bars into the reserved holes of the concrete pipe piles is large, which is not conducive to improving on-site construction efficiency.

The side groove 4 is a square groove that passes through the insertion seat 2. Multiple side grooves 4 are provided and arranged in a "+" shape. The reserved opening 5 is opened on the circular surface of the insertion seat 2, and the through opening is opened on the surface of the side groove 4, and the through opening connects the side groove 4 and the reserved opening 5. The clamping support block 7 is movably inserted into the side groove 4, and the rubber gasket 8 is fixed. The clamping support block 7 is fixed at one end that extends into the side groove 4. The other end of the clamping support block 7 is provided with an inclined surface facing the extrusion assembly. An elastic traction member is provided between the clamping support block 7 and the side groove 4. The elastic traction member includes a notch 9, a baffle 10, a rubber connecting block 11, and a pad. The notch 9 is opened on the surface of the clamping support block 7.

[0027] When the extrusion assembly extrudes and presses the clamping support block 7 along the inclined plane and slides along the through-hole, the rubber connecting block 11 is stretched and deformed. Two sets of pads are provided, both sets located below the clamping support block 7, and each set is fixed to one of the two parallel sidewalls of the side groove 4. The extrusion assembly includes a traction plate 14, a push column 15, a spring 16, a docking groove 17, a reserved groove 18, and a guide groove 19.
