Abstract
The present invention discloses a fiber concrete prefabrication member, wherein the problems of easy corrosion, easy cracking, poor fire resistance and the like of the existing concrete prefabrication member are solved with the present invention. The fiber concrete prefabrication member comprises a solid pile formed by a pile body and a tapered pile head, wherein an anticorrosion resin layer is wound on the solid pile, the pile body and the pile head comprise fiber concrete and mutually parallel steel bars in the fiber concrete, and the fiber concrete comprises the following raw materials by weight: 300-500 parts of cement, 600-800 parts of sand, 700-900 parts of aggregate, 15-25 parts of steel fibers or carbon fibers, 10-20 parts of Ethylene propylene rubber, 2-5 parts of phenol, 2-5 parts of polyvinyl alcohol, 2-5 parts of acetic ester, 15-50 parts of a water reducer, 15-50 parts of an anti-rust agent, and 30-100 parts of slag.
Description
Technical field
The present invention relates to a kind of prefabricated components, specifically, relate to a kind of fibrous concrete prefabricated components.
Background technology
Concrete, referred to as " concrete ": refer to the general designation being cemented to overall engineered composite material by gelling material by gathering materials.Usually concrete one word said refers to makes gelling material with cement, and sand, masonry gather materials; Coordinate by a certain percentage with water (can contain admixture and adulterant), the cement concrete obtained through stirring, also claims normal concrete, and it is widely used in civil engineering work.In prior art, prefabricated components use the normal concrete production cycle long, easy to crack.Due to, fibrous concrete can well inhibit carrying out of crack and can improve the multiple performance of concrete, so fibrous concrete is the effective ways improving concrete stress performance.At present, many employing Single Fiber material concrete in practical application, its reinforced effects is not good enough.On the other hand, the antiseptic power of existing concrete prefabricated components is poor, and product is short for work-ing life, and shock resistance is weak.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide a kind of and realize conveniently, production cost is low, the fibrous concrete prefabricated components of environmental protection.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of fibrous concrete prefabricated components, comprise the solid pile be made up of pile body and the pile crown in vertebra shape, described solid pile are wound with anti-corrosion resin layer, and described pile body and pile crown are by the reinforcing bar composition be parallel to each other in fibrous concrete and fibrous concrete; Described fibrous concrete is made up of the raw material of following weight part:
Preferably, described fibrous concrete is made up of the raw material of following weight part:
Further, described pile body and pile crown are also provided with epoxy resin protective layer.
Further, described cement is one or more compositions in silicate cement, high-alumina cement, phosphate cement.
Further, the rubble of described aggregate to be particle diameter be 10-20mm, the fineness modulus of described sand is 2.7.
Further, the outer wall of described solid pile is carved with some netted grooves, the outer wall of described solid pile is socketed with the fastening net be close to its outer wall, described fastening net is arranged in described groove.
Compared with prior art, the present invention has following beneficial effect:
(1) fibrous concrete of the present invention can prevent concrete cracking, improves concrete flexural strength and toughness, the fracture width of restriction, the be full of cracks of opposing concrete surface and antiknock fire resistance property.
(2) the present invention is provided with epoxy resin protective layer, adds the tension of solid pile, wear resistance.
(3) the present invention is added with rust inhibitor, water reducer in fibrous concrete, meanwhile, solid pile is also provided with anti-corrosion resin layer, can effectively avoid prefabricated components to be corroded, and improves the antiseptic power of prefabricated components.
(4) some netted grooves are carved with in the present invention on prefabricated components, be provided with fastening net, can improve the anti-pressure ability of prefabricated components in groove, extend the work-ing life of product.
