Description
Technical field:
The present invention relates to concrete structure, specifically is a kind of fiber-reinforced multi-layer cement board and preparation method thereof.
Background technology:
At present, fibre reinforced composites with its excellent mechanical property and adapt to the modern project structure to stride greatly, towering, heavily loaded, demand that lightweight develops, just be applied to more and more widely receive Structural Engineering circle extensive concern in all kinds of civil engineerings.
Fibrous composite is of a great variety, and commonly used have carbon fiber, glass fiber, basalt fibre and an aramid fiber.Have advantages such as light weight, high-strength, high-elastic mould, high temperature resistant, acid-alkali-corrosive-resisting because of it, how be widely used in reinforcing, the reinforcement fields of civil engineering with the form of boundling or fabric.
Paper-faced gyp composite plate, calcium silicates light composite board, string lightweight composite plate, cement increased pressure board all are to mix the composite board that processes by multiple materials such as fibrous material, cement; The interpolation of fibrous material has obviously improved the mechanical property of sheet material; But because fibrous material is whole blending, mostly fibrous material is the inferior grade fiber, and sheet metal thickness is thinner relatively; Lack due structural, therefore only for the sheet material of safeguarding that is used for the non-bearing requirement; The glass fiber reinforced plastic light composite board then is through fibre-reinforced compound sandwich sheet material; The sandwich structure of self has improved the plate construction performance greatly, and the also corresponding mechanical property that improves sheet material of fibrous material can be applicable to load-bearing sheet material; But its manufacturing technology is complicated, and processing cost is higher.
Summary of the invention:
The present invention is intended to solve the above-mentioned problems that existing fiber reinforced composite board exists; And provide a kind of can the implementation structure mechanical property excellent, be easy to make, be convenient to processing, can be widely used in the building structure; Can be separately use, also can be used as fiber-reinforced multi-layer cement board that the base plate of panel or the reinforced concrete slab of sandwich wall, floor uses and preparation method thereof as bearing plate.
The technical scheme that the present invention solves its technical problem employing is:
A kind of fiber-reinforced multi-layer cement board comprises cement increased pressure board, fortifying fibre grid cloth, it is characterized in that the interlayer of said cement increased pressure board is bonded with the fortifying fibre grid cloth through cementing agent.
Further, the interlayer of said layer 2-3 cement increased pressure board is bonded with 1-2 layer fortifying fibre grid cloth through cementing agent.
The preparation method of above-mentioned fiber-reinforced multi-layer cement board, carry out as follows:
A. cut out the cement increased pressure board by designing requirement, purified treatment is carried out on cement increased pressure board surface, remove floating dust and outstanding hard impurity;
B. evenly smear cementing agent on the cement increased pressure board top layer of handling well;
C. the fortifying fibre grid cloth is smooth paving is at cement increased pressure board surface layer, and stretch-draw is even all around;
D. the cement increased pressure board of the upper strata being handled well covers on the good fortifying fibre grid cloth of paving;
E. according to the bonding number of plies of instructions for use, successively process according to above sequence of construction, and carry out pressurized treatments, until reaching requirement adhesion strength standard.
The cement increased pressure board is to add the sheet material that is pressed into through press, has advantages such as lightweight and good insulation, protection against the tide, sound insulation, fire prevention, is usually used in the partition wall and the furred ceiling of building construction.But the flexural strength and the shock resistance of cement increased pressure board 1 are relatively poor, can not stand bigger load, or brittle fracture very easily takes place when standing to bend load; The fortifying fibre grid cloth has the advantage of high strength, high elastic modulus, light weight; And high temperature resistant, acid-alkali-corrosive-resisting, caking property are strong; Generally be used for the reinforcing of body of wall or decorate use; The appearance of body of wall crackle and the development in crack be can effectively prevent, structure bearing capacity and deformation performance improved.Fiber-reinforced multi-layer cement board according to the invention forms cement increased pressure board and the superimposed bonding of fibrous mesh cloth, therefore combines the common advantage of cement increased pressure board and fibrous composite.
Compared with prior art; This fiber-reinforced multi-layer cement board of the present invention has higher tension, compressive strength and excellent bending resistance, shock resistance; Fibrous mesh cloth can effectively prevent the generation and the development in crack in the cement increased pressure board; Under the greater impact load action, the fortifying fibre grid cloth impact energy that can dissipate largely improves the shock resistance of fiber-reinforced multi-layer cement board; Even under the situation that the cement increased pressure board breaks, the fortifying fibre grid cloth can also guarantee the globality of fiber-reinforced multi-layer cement board.This fiber-reinforced multi-layer cement board can carry out specification customization and cutting according to instructions for use, can improve speed of application; Can be widely used in the building structure, can use as bearing plate separately, also can be used as the panel of sandwich wall, floor or the base plate of reinforced concrete slab and use.
Description of drawings:
Fig. 1 is the fiber-reinforced multi-layer cement board structural representation that is made up of individual layer fortifying fibre grid cloth.
Fig. 2 is the fiber-reinforced multi-layer cement board structural representation that is made up of two-layer fortifying fibre grid cloth.
