Abstract
The utility model discloses a connection structure for a pile extension top and a bearing platform. The connection structure for the pile extension top and the bearing platform comprises a hollow pile extension, a basic bearing platform, end plates and anchor reinforcing bars; the basic bearing platform is connected on the pile extension top; the anchor reinforcing bars are arranged inside a pile body; the end plates are arranged at pier head positions of the anchor reinforcing bars; steel pipe sleeves are coated on the pile extension which is arranged above the end plates along the length direction; and the upper ends of the steel pipe sleeves extends outside the upper end surface of the pile extension to the basic bearing platform. The connection structure for the pile extension top and the bearing platform has the advantages of being good in force bearing, saving materials and being convenient to construct.
Description
Technical field
The utility model relates to a kind of pile extension stake top and cushion cap syndeton.
Background technology
When pile foundation is built, make a fault when work progress, make a top mark height when the cap design of pile absolute altitude, pay the utmost attention to the design elevation that reduces cushion cap, be less than twice stake when footpath when both absolute altitudes differ, adopt the pile extension stake top of national building standard design atlas 10G409 to be connected full-page proof with cushion cap.The shortcoming of the method is, the pile extension diameter is bigger than pile tube, and concrete amount is bigger, and the pile extension concrete is than the high grade of cushion cap concrete, and constructional difficulties, construction quality are difficult to guarantee.
Summary of the invention
Bigger than pile tube in order to overcome the pile extension diameter that exists in the existing pile foundation construction, concrete amount is bigger, the pile extension concrete is than the high grade of cushion cap concrete, constructional difficulties, construction quality are difficult to shortcomings such as assurance, the utility model provide a kind of power transmission better, pile extension stake top and the cushion cap syndeton of economical with materials, easy construction.
The technical solution adopted in the utility model is:
Pile extension stake top and cushion cap syndeton, comprise hollow pile extension, foundation platform, end plate, anchor bar, the stake top of described pile extension is connected with described foundation platform, be provided with anchor bar in the described pile body, described end plate is located at the reinforcing bar pier nose place of anchor bar, it is characterized in that: the pile extension of the top of described end plate is enclosed with steel pipe socket along its length, and the upper surface of pile extension is stretched out until described foundation platform in the upper end of described steel pipe socket.
Further, described syndeton comprises that also cage of reinforcement and concrete fill out core, described cage of reinforcement is located in the cavity of described pile extension, described cage of reinforcement comprises vertical muscle, stirrup and the thin steel supporting plate of circle, the thin steel supporting plate of described circle is connected the bottom of vertical muscle, built described concrete in the cavity of the pile extension of the thin steel supporting plate of described circle top and filled out core, the end face of end plate is stretched out in the upper end of described vertical muscle.
Further, described anchor bar evenly distributes along the pile body circumference.
Length with next times pile extension diameter begins to encase pile extension to the utility model steel pipe socket from pile extension stake top, at the bottom of foundation platform or grade beam, compare with former concrete pile extension, steel pipe socket directly is enclosed within on the pile extension, reduces concrete and extends out 200mm, has saved concrete, and steel pipe socket can directly serve as template, saved template, stirrup is increased to spacing 300 from spacing 100 in the steel pipe socket, has saved amount of reinforcement.Stake arranges supporting plate and puts into cage of reinforcement in the top, and pouring stake top concrete is filled out core and pile extension concrete, and its strength grade should be than cushion cap or the high grade of grade beam concrete.Steel sleeve has than strong constraint effect and steel pipe socket the pipe inner concrete and has higher shear-carrying capacity, has strengthened node strength, makes the power transmission of pile extension connecting portion better.
The utility model anchor bar and vertical muscle evenly arrange along pile extension pile body circumference, and and supporting plate weld, pallet size should be slightly less than the pile extension internal diameter, anchor bar is selected for use by the arrangement of reinforcement table, anchorage length l

The beneficial effects of the utility model are embodied in:
1, stressed better: steel sleeve has stronger constraint to the pipe inner concrete, improves concrete resistance to compression supporting capacity; Steel pipe has higher shear-carrying capacity, replaces original stirrup, has strengthened the intensity of node;
2, economical with materials: steel pipe directly is enclosed within on the pile tube and reduces concrete and extend out 200mm, has saved concrete, has saved stirrup and template;
3, easy construction: but steel pipe batch production processing, and its length scene is also regulated easily, and steel pipe can directly serve as template, the poured in place concrete convenience.
