Abstract
The invention provides a bearing platform and a construction method for connection between the bearing platform and a foundation pile. The bearing platform comprises a bearing platform main body, a conical lining and a conical depressed part, wherein the bearing platform main body is a concrete structure; the conical lining is arranged from the bottom surface of the bearing platform main body to the internal part of the bearing platform main body and is provided with a top flat surface and a side inclined surface; and the conical depressed part is arranged in the bearing platform main body and is in contact with the external surface of the conical lining. A pile head of the foundation pile which is matched with the bearing platform supports the top flat surface of the conical lining. The upper flat surface of the bearing platform is connected with a beam or a column of a building component through stirrups. Since the conical lining is arranged in the bottom surface of the bearing platform and the conical lining is connected with top (pile head) of the foundation pile in a supported way, the connection between the bearing platform and the top of the foundation pile is non-rigid connection, the connection method allows the pile head to rotate in the conical lining, the influence on the building component caused by bending torque produced by the foundation pile due to earthquakes or other reasons is reduced to a very great extent, and the damage to the component during geological change is decreased.
Description
Technical field
The present invention relates to building engineering field, the job practices that is connected with foundation pile in particular to a kind of cushion cap and cushion cap.
Background technology
At present in the building pile foundation field; Being connected between foundation pile and the cushion cap all is to adopt to be rigidly connected; That is: the reinforcing bar on the foundation pile (concrete pile of cast-in-site, piling bar, concrete precast pile etc.) is connected with the concrete bearing platform basic fixed, even also be like this in seismic design.When earthquake took place, the huge moment of deflection that is produced by earthquake can act on foundation pile and the basic joint portion of cushion cap.Being rigidly connected between foundation pile and the cushion cap basis makes can't turn round between foundation pile and cushion cap basis, thereby causes the foundation pile pile body to be destroyed easily.For self bending resistance concrete precast pile on the weak side, the moment of deflection that earthquake produces is bigger to the influence of concrete precast pile.
Summary of the invention
The present invention aims to provide the job practices that a kind of cushion cap and cushion cap are connected with foundation pile; Be rigidly connected, can't turn round to solve foundation pile and the cushion cap that job practices that cushion cap of the prior art and cushion cap be connected with foundation pile causes, thus when receiving moment of deflection easy ruined technical problem.
To achieve these goals, according to an aspect of the present invention, a kind of cushion cap is provided, has comprised: the cushion cap main body is concrete structure; The taper liner by the bottom surface of the cushion cap main body set inside towards the cushion cap main body, has plane, top and skew back face; Conical indentation, in the inside of cushion cap main body, the external surface of applying taper liner forms; The pile crown of the foundation pile that wherein, cooperates with cushion cap supports the plane, top of taper liner.
Further, the last plane of cushion cap links to each other with the fine strain of millet or the post of building unit through stirrup.
Further, the taper liner is that 1 millimeter to 4 millimeters metal sheet is made by thickness.
Further, the height of sidewall is not less than 200 millimeters.
Further, on the end face of taper liner bolt penetration hole is set.
Further, the shape of cross section of taper type depression and taper liner is circular or square or polygon, with the shape of the pile crown of cooperation foundation pile.
According to a further aspect in the invention, the job practices that provides a kind of cushion cap to be connected with foundation pile comprises: step S1 is provided with foundation pile; Step S2 places the taper liner at the top of foundation pile, and taper liner and foundation pile is fixed; Step S3 builds cushion cap on the taper liner.
Further, before step S2, also comprise: step S11, the ground of leveling, compacting cushion cap bottom; The top of cleaning foundation pile.
Further, between step S2 and step S3, also comprise: step S21, lay hardcore bed, and on hardcore bed, cover levelling with cement mortar bedding cushion on the ground in cushion cap making zone.
Further, before step S3, also comprise: step S31, to the cushion cap arrangement of reinforcement.
Further, through bolt, after step S31, before the step S3, also comprise between taper liner and the foundation pile: step S32, remove the fixedly bolt of taper liner.
Use technical scheme of the present invention; The set inside taper liner in the bottom surface of cushion cap; The taper liner again with foundation pile top (pile crown) support and connection, so be non-rigid the connection between the top of cushion cap and foundation pile, this connected mode allows pile crown in the taper liner, to rotate; Alleviated to a great extent because of earthquake or other reasons cause moment of deflection that foundation pile produces to the influence that building unit causes, the destruction that member is received when geology changes reduces.
