Description
Technical Field
The utility model belongs to the technical field of the construction pile body, concretely relates to friction in filling stake.
Background
In the early stage of engineering construction with soft soil, a friction pile needs to be poured below the earth surface, the upper part of the friction pile is of a reinforced concrete structure, the lower part of the friction pile is of a concrete structure, and the common construction mode is as follows: drilling by adopting a drilling machine, placing the bound reinforcement cage and a conduit in the hole, conveying concrete into the hole from the conduit, and pouring from the bottom; in the operation process, need put into downthehole and make its bottom unsettled with the help of hoisting machinery with the steel reinforcement cage, at the watering in-process, the gesture of steel reinforcement cage can be influenced to the concrete that flows, so often need set up locating component or compress tightly the subassembly in the upper end of steel reinforcement cage, even so, still have the risk that the steel reinforcement cage gesture changes.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at prior art's is not enough, provides a friction pile fills, and this application sets up locating component in the concrete main part, and locating component is located the downthehole of digging in advance, provides accurate location for the steel reinforcement cage.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a friction pile pours into, includes concrete body and the steel reinforcement cage that is located concrete body inside, the steel reinforcement cage outside sets up locating component, locating component includes a plurality of annular slabs that arrange along the horizontal direction, a plurality of annular slab parallel arrangement, sets up a plurality of locating plates between two adjacent annular slabs, the locating plate is inside sunken arc structure, the inboard and the steel reinforcement cage of locating plate contact.
Furthermore, a plurality of slurry permeating holes are formed in the annular plate.
Furthermore, a supporting component which is contacted with the bottom of the steel bar cage is arranged on the annular plate at the lower part of the friction pile.
Furthermore, the supporting component is made of flat plate materials, the supporting component is in a cross shape or a Chinese character 'mi' shape, and the supporting component and the annular plate are welded and fixed.
Furthermore, the supporting part is an angle steel with an upward opening, a right-angle groove is formed in the annular plate, and the supporting part is assembled in the right-angle groove and then welded and fixed with the annular plate.
The utility model has the advantages that:
1. according to the concrete cage positioning device, the positioning assembly is arranged in the concrete main body and is positioned in the pre-dug hole, so that accurate positioning is provided for the steel reinforcement cage, and potential safety hazards caused by installing the positioning assembly or the pressing assembly on the ground are reduced; the positioning assembly is used as an internal structure of the friction pile, and the pulling resistance of the friction pile can be enhanced.
2. The supporting part is fixedly arranged on the annular plate, and a supporting surface is provided for the bottom of the steel reinforcement cage, so that the use of hoisting machinery is reduced, and the safety of personnel on the operation site is ensured.

Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, the utility model discloses a friction pile fills, including concrete main part 1, steel reinforcement cage 2 and locating component all are located concrete main part 1's inside, and steel reinforcement cage 2 is located locating component.
The locating component comprises a plurality of annular plates 3 arranged in the horizontal direction, a plurality of slurry penetrating holes 4 are formed in the annular plates 3, the annular plates 3 are arranged in parallel, a supporting component 5 which is in contact with a reinforcement cage 2 is arranged on the annular plate 3 positioned at the lower part of the cast-in-place friction pile, the supporting component 5 is welded and fixed with the annular plates 3, the supporting component 5 can be flat plates or angle steel, when the supporting component 5 is a flat plate, the supporting component can be cut into a cross shape or a meter shape, when the supporting component 5 is angle steel, a right-angle groove (not shown in the figure) with an upward opening is formed in the annular plates 3, and after the supporting component 5 is assembled in the right-angle groove, the supporting component 5 and the annular plates 3 are welded and fixed by an electric welding. Set up four locating plates 6 between two adjacent annular plates 3, locating plate 6 is inside sunken arc structure, and the inboard of locating plate 6 contacts with steel reinforcement cage 2.
This application is when using, at first adopts hoisting machinery to hang the locating component and puts into the downthehole of digging in advance, then puts into the locating component with the steel reinforcement cage in, inside sunken locating plate contacts with the steel reinforcement cage, prevents that its gesture from changing, at last from the pipe to hole bottom pouring concrete can. This application has reduced through setting up locating component and has arranged hold-down mechanism on ground, and locating component formability strengthens the stretching resistance of friction pile in the concrete main part moreover.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
