Abstract
The utility model provides a prestressed concrete triangular foundation pile, comprising a pile body with a pile toe at the lower part of the pile body, and the upper part of the pile body is provided with an opposition pile body connected with the pile body. The utility model solves the problem that the triangular foundation pile has the disadvantages of poor resistance ability, poor strength and difficult steel bar prestressing treatment, and is worthy to be popularized.
Description
The utility model relates to a kind of prestressed concrete triangle foundation pile.
At present, widely used foundation pile in China's construction work, its cross section mostly are square and circular.Building expert is thought: the bearing capacity of foundation pile and the size of its surface area have direct relation.As everyone knows, leg-of-mutton girth then is far longer than square and circular girth.To this, people just think and change existing square and circular foundation pile into triangle, but the problem that due to triangle foundation pile self shape, it exists in test, and the resistance ability is relatively poor, intensity is relatively poor, prestressed, reinforced processing is difficult has been brought many worries to every aspect for a long time.
The purpose of this utility model is for solving the technical deficiency problem, a kind of prestressed concrete triangle foundation pile is provided, and its resistance ability is stronger, and higher, the prestressed, reinforced processing of intensity is easier.
The utility model is achieved through the following technical solutions: it has the bottom to have the pile body of stake point, and coupled resistance pile body is arranged at the top of pile body.
For further realizing the purpose of this utility model, can also take following technical scheme: the cross section of pile body and resistance pile body is a triangle.The prestressed reinforcement that three distributions triangular in shape are arranged respectively in pile body and the resistance pile body.The stake pin is connected with the conical mount tip of being made up of reinforcing bar, and reinforcing bar is connected with prestressed reinforcement respectively.Stirrup twines shape in the shape of a spiral around prestressed reinforcement and reinforcing bar and connects.At least one row's steel mesh is arranged at the top of stirrup.
Advantage of the present utility model: one, reasonable in design, it is provided with the resistance pile body on the top of pile body, makes resistance ability of the present utility model improve greatly; It twines prestressed reinforcement with the stirrup spiral, makes it stressed quite even, so improved the intensity of foundation pile greatly; Link together again after conical mount and the prestressed reinforcement be made up of three reinforcing bars that it will have a pin made respectively, handled, make that in advance three main reinforcements to be carried out autofrettage very easy: two, simple in structure, easy making, with low cost, easy to use and reliable.Extensive use of the present utility model can produce good social, economic benefit.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1;
Fig. 4 is the C-C view of Fig. 1;
Fig. 5 is the D-D view of Fig. 1.
In conjunction with the embodiments the utility model is described in further detail with reference to the accompanying drawings.
Prestressed concrete triangle foundation pile of the present utility model, it has the bottom to have the pile body 4 of stake point, and coupled resistance pile body 3 is arranged at the top of pile body 4.The cross section of pile body 4 and resistance pile body 3 is a triangle.The prestressed reinforcement 5,10,11 that three distributions triangular in shape are arranged respectively in pile body and the resistance pile body.Stake pin 7 is connected with the conical mount tip of being made up of reinforcing bar 6,8,9, and reinforcing bar 6,8,9 is connected with prestressed reinforcement 5,11,10 respectively.Stirrup 2 twines shape in the shape of a spiral around prestressed reinforcement 5,10,11 and reinforcing bar 6,8,9 and connects.At least one row's steel mesh 1 is arranged at the top of stirrup 2.
During making, the stirrup of making in advance 2 is placed in the mould, prestressed reinforcement 5,11,10 is passed from stirrup 2, tensioned prestressing bar 5,11,10 then.After stretch-draw finished, the conical mount of being made up of 3 reinforcing bars 6,8,9 that will have a pin 7 placed in the mould, and was connected with presstressed reinforcing steel 5,11,10 respectively, on the top of stirrup 2 which floor steel mesh 1 was set again.After finishing above-mentioned operation, can in mould, pour into the concrete of different formulations, make bottom of the present utility model and top form pile body 4 and resistance pile body 3.
