Abstract
The utility model provides a kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building, former single footing is provided with some stake holes, foundation pile is provided with in stake holes, described Under Pile top is fixed by cushion cap steel mesh reinforcement, and described cushion cap steel mesh reinforcement implants reinforcing bar by new-old concrete interface, the connecting reinforcement of vertical dowel, foundation pile and cushion cap forms.It has very high vertical bearing capacity of single pile or Bearing Capacity of Pile Groups, is enough to bear the very large load in top; There is larger rigidity, do not produce large differential settlement, ensure stability; Punching Shear and bending resistance are strengthened; Former basis applies, and operation is simple; Not reducing under the load-carrying properties of existing single footing, can greatly improve existing bearing characters, improving foundation bearing capacity.
Description
Technical field
The utility model relates to construction engineering technical field, is specifically related to a kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building.
Background technology
This patent belongs to foundation underpinning field, former single footing is carried out improvement and becomes pile foundation of bearing platform plinth, both taken full advantage of former basis, turn improved bearing capacity of foundation soil, ensure that superstructure safety and stability, be with a wide range of applications.Particularly in soft foundation, the high-bearing capacity of pile foundation of bearing platform plinth and large rigidity are the effective ways solving bearing capacity of foundation soil deficiency and differential settlement.
Along with the raising of China's expanding economy and the urbanization level, urban built-up land is more and more nervous, and land price is more and more expensive, urban space is more and more crowded, the propelling of urbanization process, more and more will build band especially to small towns, it is of common occurrence that high building is played on level land.In construction, may run into an a large amount of basic difficult problem, underpin becomes important topic.And the building that China is early stage, most service life is not high, and removing to rebuild then needs at substantial physical resources and financial resources, so transformation reinforcing technique also more and more comes into one's own.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building, it solves these above-mentioned problems.
The technical scheme that the utility model adopts is as follows: a kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building, former single footing is provided with some stake holes, foundation pile is provided with in stake holes, described Under Pile top is fixed by cushion cap steel mesh reinforcement, and described cushion cap steel mesh reinforcement implants reinforcing bar by new-old concrete interface, the connecting reinforcement of vertical dowel, foundation pile and cushion cap forms.
Preferably, described foundation pile is 4-8.
The beneficial effects of the utility model comprise:
1, there is very high vertical bearing capacity of single pile or Bearing Capacity of Pile Groups, be enough to bear the very large load in top;
2, there is larger rigidity, do not produce large differential settlement, ensure stability;
3, Punching Shear and bending resistance are strengthened;
4, apply on former basis, operation is simple;
5, not reducing under the load-carrying properties of existing single footing, can greatly improve existing bearing characters, improving foundation bearing capacity.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building of the utility model;
Fig. 2 is the top view of a kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building of the utility model.
In figure: 1, existing structure post; 2, new-old concrete interface implants reinforcing bar; 3, vertical dowel; 4, former basis becomes cushion cap after thickening; 5, former single footing; 6, plain concrete backing plate; 7, foundation pile; 8, former single footing; 9, the connecting reinforcement of foundation pile and cushion cap.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of pile foundation of bearing platform plinth structure of being reinforced by the single footing of existing building, as shown in Figure 1, 2, former single footing 5 is provided with some stake holes, foundation pile 7 is provided with in stake holes, described foundation pile 7 top is fixed by cushion cap steel mesh reinforcement, and described cushion cap steel mesh reinforcement implants reinforcing bar 2 by new-old concrete interface, the connecting reinforcement 9 of vertical dowel 3, foundation pile and cushion cap forms.
Described foundation pile 7 is 4-8.
Above-mentioned embodiment is preferred embodiment of the present utility model; be not for limiting enforcement of the present utility model and interest field; all equivalences made according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model claim.
