Abstract
The utility model relates to a tubular pile, and particularly provides a bearing platform anti-seismic tubular pile provided with a sectional pile cavity and a filled core. The structure of the bearing platform anti-seismic tubular pile provided with the sectional pile cavity and the filled core comprises a tubular pile body. End plate iron pieces are arranged on the two ends of the tubular pile body, shroud rings are arranged on the end plate iron pieces and the outer sides of the end portions of the tubular pile body in a covering mode, core concrete is filled inside the tubular pile, and the core concrete is arranged between a supporting plate arranged inside the tubular pile body and the end plate iron pieces in a sealing and fixed mode. Compared with the prior art, the bearing platform anti-seismic tubular pile provided with the sectional pile cavity and the filled core has the advantages of being reasonable in design, simple in structure, low in processing and manufacturing cost, high in fixing stability, and capable of resisting a seism.
Description
Technical field
The utility model relates to a kind of pile tube, specifically provides on a kind of cushion cap a joint stake inner chamber to fill out core antidetonation pile tube.
Background technology
Pile body top under the pile tube under the prior art, itself and cushion cap junction and cushion cap comprises that cushion cap fills out the joint portion of core, under the compound actions such as press-bending, shearing, be easy to destroyed, liquefaction soil layers and soft or hard layer interface place, stake cross section moment of flexure, shear value are very large.When earthquake occurs, liquefaction soil layers produces larger displacement, produces larger shear stress in the pile body cross section, follows simultaneously larger flexural deformation, is easy to make the pile body curved scissors to destroy.
Summary of the invention
The utility model is for above problem, provides on a kind of cushion cap a joint stake inner chamber to fill out core antidetonation pile tube, and it can strengthen tubular pile body and cushion cap node and end shear resistance, thereby it is possessed to earthquake-resistant speciality.
The technical scheme that its technical problem that solves the utility model adopts is:
Joint stake inner chamber is filled out core antidetonation pile tube on a kind of cushion cap, comprise the pile tube body, pile tube body two ends are provided with the end plate iron plate, described end plate iron plate and the pile tube body end outside are coated with shroud ring, described pile tube body interior is filled with core concrete, describedly fills out the core concrete sealing between the supporting plate that is arranged at the pile tube body interior and described end plate iron plate or pile crown.
Fill out and be provided with cage of reinforcement in the core concrete.
Joint stake inner chamber is filled out core antidetonation pile tube on a kind of cushion cap of the present utility model, pile tube is provided with supporting plate, supporting plate is fixed on to the place of next end pile tube apart from end plate iron plate 1m-1.5m, be filled with core concrete (fill out core concrete and adopt slightly expanded concrete) in the cavity of supporting plate apart from the place of end plate iron plate 1m-1.5m, put into cage of reinforcement in the filled core concrete, increase with cushion cap and be connected and fixed, its steel reinforcement framework cage of joining is good through experimental design, pile tube and pile body top, cushion cap joint portion comprise that cushion cap fills out core cross section plastic hinge and destroy, the stake top applies axial pressure and keeps constant, then the pile body section at the pile crown position applies the horizontal reciprocating load, determines the stress performance of pipe pile end under the different distortion, failure pattern and mechanism.
Compared with prior art, a joint stake inner chamber is filled out core antidetonation pile tube on a kind of cushion cap of the present utility model, its have reasonable in design, simple in structure, the processing and fabricating cost is low, stability maintenance is high, characteristics that can antidetonation.
Description of drawings
Fig. 1 is the overall structure front view (embodiment 1) that joint stake inner chamber is filled out core antidetonation pile tube on a kind of cushion cap;
Fig. 2 is the overall structure schematic diagram (embodiment 2) that joint stake inner chamber is filled out core antidetonation pile tube on a kind of cushion cap.
The specific embodiment
Below in conjunction with the drawings and specific embodiments joint stake inner chamber on a kind of cushion cap of the present utility model being filled out core antidetonation pile tube is further described.
Embodiment 1:
As shown in Figure 1, joint stake inner chamber is filled out core antidetonation pile tube on a kind of cushion cap, comprise pile tube body 1, pile tube body 1 two ends are provided with end plate iron plate 2, described end plate iron plate 2 and the outside, pile tube body 1 end are coated with shroud ring 3, described pile tube body 1 inside is filled with core concrete 4, describedly fills out core concrete 4 sealing between the supporting plate 5 that is arranged at pile tube body 1 inside and described end plate iron plate 2.
Embodiment 2:
As shown in Figure 2, the difference of present embodiment and embodiment 1 is, fills out and is provided with cage of reinforcement 6 in the core concrete 4, and the reinforcing bar of its cage of reinforcement 6 extends in the cushion cap, makes cushion cap with concrete matched.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
Claims (2)
1. a joint stake inner chamber is filled out core antidetonation pile tube on the cushion cap, comprise the pile tube body, it is characterized in that, pile tube body two ends are provided with the end plate iron plate, described end plate iron plate and the pile tube body end outside are coated with shroud ring, described pile tube body interior is filled with core concrete, describedly fills out the core concrete sealing between the supporting plate that is arranged at the pile tube body interior and described end plate iron plate.
