Abstract
The invention discloses an uplift pile with prestress reinforced plastic rods, which comprises a pile body, and post-tensioned prestressing reinforced plastic rods or pipes are arranged longitudinally inside the pile body. A reinforced plastic rod or pipe is arranged on an axle wire inside the pile body, or a plurality of reinforced plastic rods or pipes are arranged on a circumference inside the pile body. According to the uplift pile with prestress reinforced plastic rods, metal materials are replaced with the reinforced plastic rods and the reinforced plastic rods are used for producing the uplift pile, post-tensioned prestressing processing of the reinforced plastic rods is performed, so that the overall performance of the pile body is maintained and production cost of the uplift pile and the construction cost are reduced simultaneously. The disassembly construction is facilitated due to the fact that the reinforced plastic rods belong to hard brittle materials which are weak in anti-breakage performance.
Description
Technical field
The present invention relates to technical field of civil engineering, be specifically related to the pile body structure of resistance to plucking of anti-floating and the above ground structure of underground structure.
Background technology
In the higher area of groundwater table, when the superstructure loading can not the balance buoyancy force of underground water, the whole or local effect that will receive upward force of structure.In order to overcome the effect of this upward force, all uplift pile must be set like the basement structure of underground structure.Present uplift pile has prefabricated reinforced concrete structure, prefabricated ordinary concrete structure, also has the cement-soil structure of in-site pouring; But no matter be to use any structure; All be provided with reinforcing bar or prestressed reinforcement in the pile body, for example the patent No. is exactly in the uplift pile of cement-soil structure, to be provided with the steel strand cable for " 201020210569 " open name is called " a kind of uplift pile structure "; The patent No. is called for " 2010100396725 " open name for another example: " a kind of basement uplift pile structure " is exactly that prestressed reinforcing bar is set in prefabricated pile body.Prestressed reinforcing bar is set in prefabricated pile body, has improved resistance to plucking, the anti-cracking performance of pile body, the safety that has improved building.But use reinforcing bar as the difference muscle, can the cost of manufacture of pile body be high, prepare uplift pile with the substitution material of reinforcing bar, reduces the cost of uplift pile, is the technical problem that the industry will be researched and solved.
Summary of the invention
The technical problem that the present invention will solve provides a kind of uplift pile that is provided with prestressing force reinforced plastic bar, under the condition that keeps the pile body overall performance, can reduce the cost of uplift pile, the convenient dismounting.
The present invention realizes through following technical scheme:
A kind of uplift pile that is provided with prestressing force reinforced plastic bar comprises pile body, vertically is provided with post-tensioned prestressing reinforced plastic bar or tubing in the said pile body.
The further improvement project of the present invention is, said reinforced plastic bar or tubing are provided with one, be positioned on the pile body axis, or said reinforced plastic bar or tubing is provided with many, is positioned at one week of pile body.
The present invention further improvement project is, said bar or tubing lower end are fixedly connected with stopping means, and the upper end is provided with connector, and said bar or tubing top between connector and stopping means are provided with sleeve pipe, bottom and pile body bonding.
The present invention further improvement project is, said bar or tubing are provided with screw thread in two ends up and down, and the stopping means that said lower end connects firmly and the connector of upper end are nut; Or the upper end is provided with screw thread, and said connector is a nut, and the stopping means that the lower end connects firmly is enlarged footing (integral molded plastic forms).
The present invention further improvement project is to be provided with backing plate in the inboard of upper and lower side nut.Nut is plastics or metal material, or with said bar or tubing be same material.
The present invention further improvement project is that said bar or tubing are carbon fiber, glass fiber or aromatic polyamide fiber reinforced plastics bar or tubing.Reinforced plastic bar or tubing abbreviation: FRP, carbon fiber, glass fiber or aramid fiber bar or tubing abbreviation are respectively: CFRP, GFRP, AFRP.According to the relevant document record, the compressive strength of reinforced plastic bar is more than the twice of reinforcing bar, and its price is lower than reinforcing bar.
The present invention further improvement project is that said sleeve pipe is plastic pipe or is metal tube.
The present invention compared with prior art has following obvious advantage:
One, the present invention makes post-tensioned prestressing to it simultaneously and handles with reinforced plastic bar or the uplift pile of tubing alternative metals material, can keep the overall performance of pile body, can reduce cost of manufacture, the reduction construction costs of uplift pile again.
Two, because the reinforced plastic bar belongs to fragile material, anti-fracture ability a little less than, therefore made things convenient for and removed construction.
Description of drawings
Fig. 1 is the axial cross-sectional schematic of the present invention (the pile body axis is provided with a bar).
Fig. 2 is Figure 1A-A cross-sectional schematic.
The specific embodiment
Like Fig. 1, shown in 2, the present invention includes pile body 1, vertically be provided with post-tensioned prestressing reinforced plastic bar 2 in the said pile body 1.Said reinforced plastic bar 2 is arranged on the pile body 1 interior axis.
As shown in Figure 1, said bar is provided with screw thread 3 in two ends about in the of 2, and upper and lower side is fixedly connected with nut 4 respectively, and bar 2 tops between the nut 4 of upper and lower side are provided with sleeve pipe 5, bottom and pile body bonding.Said sleeve pipe 5 is a plastic pipe.The bar surface that is positioned at sleeve pipe is smooth surface.Be provided with backing plate 6 in the inboard of upper and lower side nut 4.Said nut 4 is a plastic material.
In the present embodiment, said reinforced plastic bar is the carbon fiber bar, and the diameter of reinforced plastic bar is 10mm (diameter of rod is according to the size setting of pile body holding capacity).
Axial week etc. is arranged with four glass fiber reinforced plastics bars (diagram is not provided) in the pile body of uplift pile.The bar lower end is provided with enlarged footing, and the diameter of said enlarged footing is greater than diameter of rod, and the enlarged footing side projection is trapezoidal or triangle.All the other are implemented like embodiment 1.
After the pile body perfusion was good, cushion cap was done in the upper end.Wait to reach certain intensity, the nut stretch-draw bar that turns the bar upper end makes it have prestressing force.
The present invention is equally applicable to have the pile body of similar structures.Everyly in pile body, be axially arranged with prestressing force reinforced plastic bar or tubing, all belong to protection domain of the present invention.
