Abstract
The utility model relates to a pile used for surface buildings, in particular to a high-performance and low-prestressed concrete solid pile. The pile comprises a pile body and a pile head, wherein the pile body consists of one or more sections; each section of pile body consists of concretes and reinforcing steel bars that are parallel with each other in the concretes; the two ends of each of the reinforcing steel bars are respectively connected with connecting discs; two adjacent connecting discs are welded to form the pile body; a pile head is conical; the pile is characterized in that: two connecting discs are wound by anti-corrosion resin layers; carbon fiber layers capable of improving anti-corrosion ability and tensile ability are arranged on the anti-corrosion resin layers; an epoxy resin protective layer is arranged on the reinforcing steel bar exposed on the pile head. According to the high-performance and low-prestressed concrete solid pile disclosed by the utility model, the protective layers are added for exposed connecting discs, connection positions of the reinforcing steel bars and the connecting discs, and a pile toe; moreover, with use of the protective layers, tensile ability and wear resistance of the pile are enhanced; the pile has the advantages of being simple in technique, good in anti-corrosion effect, long in service life, and the like.
Description
Technical field
The utility model relates to the stake that surface structures uses, specifically the high-performance lower-prestressed concrete solid pile of high, the long service life of a kind of corrosion resistance.
Background technology
As everyone knows, the special durability regulation that proposes concrete stake in pile foundation 08 standard, particularly coastal area, the in situ pile that routine is selected and pile for prestressed pipe, if emphasize in standard most preferred side's Prefabricated concrete solid pile under deep-etching situation, under square one compared with hollow shell pill, solid pile can increase the corrosion allowance of concrete, compared with castinplace pile, in formation of pile, do not blend with corrosivity Tu Shui, existing concrete solid pile is by pile body, pile crown composition, pile body is made up of a joint or more piece, every joint pile body is made up of the reinforcing bar being parallel to each other in concrete and concrete, the two ends of reinforcing bar are connected with plate-like terminal pad respectively, two terminal pads weld again, pile crown is tapered, sink with guiding pile body, its deficiency is reinforcing bar and the corrosivity Tu Shui blending at terminal pad and terminal pad place, erosion resistance is poor, affect application life.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides that a kind of technique is simple, the high-performance lower-prestressed concrete solid pile of favorable anti-corrosion effect, long service life.
The utility model solves the technical scheme that its technical problem adopts.
A kind of high-performance lower-prestressed concrete solid pile; comprise pile body, pile crown; pile body is made up of a joint or more piece; every joint pile body is made up of the reinforcing bar being parallel to each other in concrete and concrete; the two ends of reinforcing bar are connected with terminal pad respectively; adjacent two terminal pads weld and form pile body; pile crown is tapered; it is characterized in that two terminal pads are wound around anti-corrosion resin layer; anti-corrosion resin layer is provided with the carbon fiber layer that can improve antiseptic power and resistance to tension, and pile crown place exposed steel bar is provided with epoxy resin topping.
The thickness of anti-corrosion resin layer described in the utility model is not less than 1.5mm, and the thickness of carbon fiber layer is at least one deck carbon cloth one deck, and the thickness of epoxy resin topping is 1.5mm, carbon fiber layer parcel anti-corrosion resin layer.
The utility model is to the terminal pad exposing, reinforcing bar and be connected junction and pile top interpolation topping, and topping has also increased its tension, wear-resistant ability in addition, has the advantages such as technique is simple, favorable anti-corrosion effect, long service life.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
As shown in the figure, a kind of high-performance lower-prestressed concrete solid pile, comprise pile body, pile crown 1, pile body is made up of a joint or more piece, every joint pile body is made up of the reinforcing bar 1 being parallel to each other in concrete and concrete, the two ends of reinforcing bar 1 are connected with terminal pad 2 respectively, adjacent two terminal pads 2 weld and form pile body, pile crown 1 is tapered, it is circular that described terminal pad can be, square hollow etc., above-mentioned same as the prior art, this does not repeat, of the present utility model being characterised in that in two terminal pad circumferential perimeter is wound around through smearing anti-corrosion resin layer 4, anti-corrosion resin layer 4 is provided with the carbon fiber layer 5 that can improve antiseptic power and resistance to tension, pile crown place exposed steel bar is provided with epoxy resin topping 6, the thickness of anti-corrosion resin layer described in the utility model is not less than 1.5mm, the thickness of carbon fiber layer is at least one deck carbon cloth one deck, the thickness of epoxy resin topping is 1.mm, fibrage parcel anti-corrosion resin layer, the utility model is to the terminal pad exposing, reinforcing bar be connected junction and pile top and add topping, topping has also increased its tension in addition, wear-resistant ability, there is technique simple, favorable anti-corrosion effect, the advantages such as long service life.
