Abstract
This utility model is a kind of enlarged footing damping end-bearing pile, this utility model is the end-bearing pile of a kind of special construction, this kind of end-bearing pile end expanding is truncated cone-shaped, and below end, it is fixedly connected with foamed resin buffer layer, this kind of structure can increase end-bearing pile base area, the contact area of end-bearing pile and substrate can be improved simultaneously, improve bearing capacity, increase the stability of end-bearing pile.
Description
Technical field
This utility model relates to building structure field, particularly relates to a kind of enlarged footing damping end-bearing pile.
Background technology
Building field end-bearing pile refers to that pile top load is entirely or essentially held by end resistance under vertical limit load action
Being subject to, pile side resistance is less relative to for end resistance, or negligible stake, due to stake top major part load by end-bearing pile at the bottom of
Face, when being given a shock, damping problem is difficult to solve always.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of enlarged footing damping end-bearing pile, can increase end-bearing pile end
Portion's area, improves bearing capacity, improves the damping energy absorption ability of end-bearing pile simultaneously.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of enlarged footing damping end-bearing pile, is characterized in that: end-bearing pile includes in the middle part of end-bearing pile top, end-bearing pile and end-bearing pile
Bottom, described end-bearing pile top is connected by armored concrete with cushion cap, outwards expands bottom described end-bearing pile, is formed and expands
Major part, links together, bottom described end-bearing pile by the middle part of end-bearing pile bottom described end-bearing pile top and end-bearing pile
The foamed resin buffer layer for damping energy-absorbing it is equipped with below enlarged footing.
For optimizing above-mentioned utility model, the concrete measure taked also includes:
It is cylindrical reinforced concrete structure in the middle part of described end-bearing pile top and end-bearing pile.
The described enlarged footing bottom end-bearing pile is truncated conical shape.
Seamlessly transit between described end-bearing pile pile and end-bearing pile enlarged footing.
Described foamed resin buffer layer is fixing with enlarged footing to be connected.
Thickness is height of enlarged base the 1/4 to 1/3 of described foamed resin buffer layer.
Under in this utility model, end-bearing pile is vertical limit load effect, load major part in stake top is held by bottom end-bearing pile
Being subject to, fraction load is offset by the frictional force between end-bearing pile and substrate, expands and forms enlarged footing, increase end bottom end-bearing pile
Hold the area bottom stake, bottom end-bearing pile, below enlarged footing, be fixedly connected with the buffer layer being made up of foam resin, damping
Layer further increases the area of end-bearing pile bearing load, also further increases the bearing capacity of end-bearing pile, on the other hand
Also increasing the contact area of end-bearing pile and substrate, improve the stability of end-bearing pile, foamed resin buffer layer has energy-absorbing damping
Function, be laid on the foamed resin buffer layer bottom end-bearing pile can reduce external shock to end-bearing pile apply axial stress shadow
Ring, it is achieved that the function of enlarged footing damping.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model a kind of enlarged footing damping end-bearing pile.
Marginal data: 1, end-bearing pile top；2, in the middle part of end-bearing pile；3, bottom end-bearing pile；4, foamed resin buffer layer.
Detailed description of the invention
Below in conjunction with Figure of description and concrete preferred embodiment, this utility model is further described.
A kind of enlarged footing damping end-bearing pile, is characterized in that: end-bearing pile include in the middle part of end-bearing pile top 1, end-bearing pile 2 and end hold
Bottom Zhuan 3, described end-bearing pile top 1 is connected by armored concrete with cushion cap, and bottom described end-bearing pile, 3 outwards expand,
Forming enlarged footing, bottom described end-bearing pile top 1 and end-bearing pile, 3 link together by the middle part of end-bearing pile 2, and described end holds
The foamed resin buffer layer 4 for damping energy-absorbing it is equipped with below the enlarged footing of 3 bottom Zhuan.
In the present embodiment, in the middle part of end-bearing pile top 1 and end-bearing pile, 2 are cylindrical reinforced concrete structure.
In the present embodiment, bottom end-bearing pile, the enlarged footing of 3 is truncated conical shape.
In the present embodiment, seamlessly transit between end-bearing pile pile and end-bearing pile enlarged footing.
In the present embodiment, foamed resin buffer layer 4 is fixing with enlarged footing to be connected.
In the present embodiment, thickness is height of enlarged base the 1/4 to 1/3 of foamed resin buffer layer 4.
Under in this utility model, end-bearing pile is vertical limit load effect, load major part in stake top is held by bottom end-bearing pile 3
Being subject to, fraction load is offset by the frictional force between end-bearing pile and substrate, and bottom end-bearing pile, 3 expand formation enlarged footing, increase
The area of 3 bottom end-bearing pile, is fixedly connected with the buffer layer being made up of foam resin below 3 enlarged footings bottom end-bearing pile,
Buffer layer further increases the area of end-bearing pile bearing load, also further increases the bearing capacity of end-bearing pile, at another
Aspect also increases the contact area of end-bearing pile and substrate, improves the stability of end-bearing pile, and foamed resin buffer layer 4 has energy-absorbing
The function of damping, is laid on the foamed resin buffer layer 4 of bottom end-bearing pile 3 and can reduce external shock and apply axially should to end-bearing pile
The impact of power, it is achieved that the function of enlarged footing damping.
Below being only preferred implementation of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It is right to it should be pointed out that,
For those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise,
Should be regarded as protection domain of the present utility model.
