Internal surface layer 3 is fiber concrete surface layer, and the fiber concrete surface layer is by water, cement, fine aggregate, flyash, silicon
Ash, granulated blast-furnace slag, water reducer, fiber composition.The concrete topping has fiber due to adding, and can effectively improve coagulation
The tensile strength and toughness of native surface layer.
Outer coversheet 1 is automatically cleaning fiber concrete surface layer, and the composition of automatically cleaning fiber concrete is：Water, cement, fine bone
Material, flyash, silicon ash, granulated blast-furnace slag, water reducer, fiber, nano titanium oxide.The nano-silica added in outer coversheet 1
Change titanium as catalyst, can speed up degraded of the pollutant of automatically cleaning fiber concrete facing surface under ultraviolet irradiation,
It ensure that the sanitary characteristics of outer coversheet.
The surface of outer coversheet 1 is undaform, improves the daylighting area on the surface of outer coversheet 1, improves the degradation rate of pollutant,
Meanwhile, undaform wallboard is conducive under natural conditions, the spot on rain drop erosion wallboard.
Inner core plates 2 are equidistantly provided with including trapezoidal groove 4, the outer coversheet 1 and internal surface layer 3 of concrete panel along short transverse
The corresponding position of trapezoidal groove 4 of core plate 2 is provided with trapezoidal concrete 5, inserts the trapezoidal concrete 5 of concrete topping from side during connection
In the trapezoidal groove 4 for entering inner core plates 2, close connection is allowed to.
The hypotenuse of trapezoidal groove 4 and the angle of vertical direction are 30 °~60 °, the base length of trapezoidal groove 4, height,
Away from being determined according to actual engineering design.
The composition of inner core plates 2 is foam concrete.
Compared with prior art, Light trabses proposed by the present invention have the advantages that：
1) there is self-cleaning function
Nano titanium oxide in the Light trabses outer coversheet of the present invention can improve the degraded of the pollutant of surfaces of wall,
Through experimental study, the Light trabses, up to more than 80%, keep building appearance to the resolution ratio of oxynitrides and sulfide
Face it is bright and clean.The self-cleaning material performance is stable, non-toxic to humans and can reuse, and realizes sustainable function.
2) there is the ability of preferable cracking resistance
Fiber in the surface layer of the Light trabses of the present invention effectively improves the tensile strength of panel, improves wallboard cracking resistance
Ability, reduce the cracking in crack, the excellent mechanical property of wallboard ensure that while wallboard quality is reduced.
3) have the advantages that deadweight it is small, insulation, it is heat-insulated
The present invention Light trabses inner core composition be foam concrete, can effectively improve wallboard insulation,
Sound insulation value, and the quality of wallboard can be mitigated.
