Abstract
The utility model discloses a PVC pipe concrete column which is wrapped by glass fiber cloth, wherein the component is composed by a PVC pipe which is wrapped by the glass fiber cloth and filled with with concrete, wherein epoxy resin is used to adhere the glass fiber cloth on the outer surface of the PVC pipe, and the concrete is poured in the pipe to form the PVC pipe concrete column which is wrapped by the glass fiber cloth, the wrapping layer number of the glass fiber cloth is one to eight, the thickness of the material of the glass fiber cloth is 0.1mm to 0.3mm, the intensity of the concrete which is poured into the pipe is C30 to C60, the number of reinforcing bars which are contained in the PVC pipe concrete column which is wrapped by the glass fiber cloth is same with the number of the reinforcing bars which are contained in a common armored concrete column, and the PVC pipes adopt the PVC pipes which are bought from markets or customize PVC pipes with the wall thickness from 2 to 30mm and with different pipe diameters. The structure column has reasonable stress performance, corrosion prevention, strong deforming ability, convenient construction, low cost and extending and applicable value.
Description
Technical field
The utility model belongs to the structural element of construction work, relates to a kind of be applied to effectively to improve ordinary concrete columns bearing capacity, strong and cheap construction work post member---the fiberglass cloth coating PVC pipe concrete pile of corrosion resistance.
Background technology
The steel core concrete column that penetration concrete forms in steel pipe belongs to the hoop concrete member.Steel pipe not only bears longitudinal loading, simultaneously core concrete is applied horizontal restrain, makes it be in the three dimension stress state, delays the generation and the development of its vertical microcrack, thereby improves its compressive strength and compression deformation ability.But steel core concrete column itself also has some outstanding defectives, and specifically have: the price of (1) steel own is higher, uses in extensive building structure, makes building costs increase; (2) poor corrosion resistance of steel, maintenance cost is very high.
Summary of the invention
The purpose of this utility model is: the problem at prior art exists under the prerequisite that does not increase engineering cost, proposes a kind of mechanical property and superior, cheap a kind of building structure post of antiseptic property that can improve concrete column.
Content of the present utility model is a fiberglass cloth coating PVC pipe concrete pile.
The utility model is to form glass fabric-pvc pipe at the pvc pipe skin by sticking glass fabric, and fluid concrete forms fiberglass cloth coating PVC pipe concrete pile in this pipe then, and structure as shown in Figure 1.
The above-mentioned glass fabric parcel number of plies is 1 layer to 8 layers, and the glass fabric material thickness is 0.1mm～0.3mm.
The strength grade of concrete of cast is C30～C60 in the aforementioned tube.
The arrangement of reinforcement that above-mentioned fiberglass cloth coating PVC pipe concrete pile contains is identical with the arrangement of reinforcement quantity that the ordinary reinforced concrete post should contain.
Above-mentioned pvc pipe uses the pvc pipe of market purchase or the pvc pipe of customization wall thickness 2～30mm different tube diameters.
Compare with concrete column traditional in the prior art, the beneficial effects of the utility model are:
(1) mechanical property effectively improves.After fill concrete formed glass fabric-pvc pipe confined concrete post in fiberglass cloth coating PVC pipe, glass fabric-pvc pipe had retrained concrete, under the axial compression load action, and concrete three dimension stress, the longitudinal cracking when having delayed pressurized.And the too early generation cripling of glass fabric-pvc pipe can be avoided or delay to concrete existence, two kinds of materials have remedied weakness each other mutually, can give full play to strong point each other, thereby make this new structural member have very high bearing capacity, be higher than glass fabric-pvc pipe and the independent bearing capacity sum of core concrete of forming new structural member.
(2) economic benefit is given full play to.As a kind of comparatively reasonable structure form, adopt glass fabric-pvc pipe confined concrete can bring into play glass fabric, PVC material and three kinds of properties of materials of concrete and potentiality well, make material obtain more abundant and rational application.And glass fabric-pvc pipe confined concrete and concrete filled steel tube are similar, engineering is actual in a large number shows, adopt the compression-member of concrete filled steel tube can save concrete 50% than the auspicious pact of ordinary reinforced concrete pressure-bearing structure, alleviate dead load about 50%, rolled steel dosage is slightly high or rough equal; Compare with steel work, can save steel about 50%. therefore, glass fabric-pvc pipe confined concrete also can have similar benefit, has good economic effect.
(3) easy construction.Glass fabric-pvc pipe concrete column concrete in itself belongs to hoop concrete, and glass fabric-pvc pipe itself is exactly the template of anti-side pressure, when placing of concrete, can save the construction of template, and can adapt to advanced pump concrete placing technology.Therefore glass fabric-pvc pipe constraint high performance concrete post can be simplified installation technology, reduce construction land tenure and reduction of erection time.
Compare with steel core concrete column, the beneficial effects of the utility model are:
(1) antiseptic property is good.Glass fabric-pvc pipe is as member external maintenance material, and its abrasion resistance and tough elasticity are good, and glass fabric and PVC material molecule do not have polarity, so chemical stability is good, the corrosion of the various acid of ability, alkali, cold-resistant, anti-solarization, wear-resistant is guaranteed more than 50 years application life.
(2) two kinds of material prices of glass fabric and PVC are cheap, evidence, and when improving 1 times of ordinary concrete columns bearing capacity, its price only is about 1/2 of a steel pipe price.
Description of drawings
Fig. 1 is the utility model---the cross-sectional view of glass fabric-pvc pipe post.
Number in the figure explanation: 1-glass fabric; 2-pvc pipe; 3-concrete.
The specific embodiment
The cross-sectional structure of the utility model glass fabric-pvc pipe concrete column as shown in Figure 1, be followed successively by glass fabric, pvc pipe, concrete from outside to inside, it can be according to requirement of engineering, the choose reasonable glass fabric is pasted the number of plies, pvc pipe wall thickness, member section size and length, and the inner form of reinforcement of post, this glass fabric-pvc pipe can be prefabricated in the factory.
The glass fabric parcel number of plies and thickness are according to circumferential tightening force of member in the Structural Engineering and the different variations of distortion size requirements.Strength grade of concrete adopts the different intensity grades concrete according to member anti-pressure ability difference in the Structural Engineering.The inner arrangement of reinforcement of fiberglass cloth coating PVC pipe concrete pile adopts multi-form arrangement of reinforcement according to design bearing capacity difference in the Structural Engineering, as reinforcing bar, and bamboo reinforcement, reinforcing bar; Arrangement of reinforcement quantity is prepared according to design bearing capacity in the Structural Engineering is different.
The utility model fiberglass cloth coating PVC pipe concrete pile, the tool stress performance is reasonable, corrosion-resistant, deformability strong, easy construction, and is cheap, has bigger application value, especially in the building structure in the abominable area of environment.
