Description
Technical Field
The invention relates to the technology in the field of wallboards, in particular to a phosphogypsum-based light reinforced inner partition board.
Background
At present, most prefabricated wall body battens used for partition walls in buildings are cement-based, such as glass fiber reinforced cement battens, steel wire (steel wire mesh) reinforced cement battens, lightweight concrete battens and the like. The other cementing material, gypsum, can completely become a substitute for cement in the field due to more outstanding energy-saving and environment-friendly characteristics, and glass fiber reinforced gypsum hollow laths, composite sandwich gypsum-based light laths and the like have been developed at present. The phosphogypsum is one of gypsum materials, belongs to industrial waste, and has more environmental protection value and lower cost compared with natural gypsum. The preparation method of the anhydrous phosphogypsum-based assembled light partition wall batten (CN 110105039A) provides a preparation method of the anhydrous phosphogypsum-based assembled light partition wall batten, and adopts materials such as anhydrous phosphogypsum, semi-hydrated phosphogypsum, gypsum whiskers, an air entraining agent, a water-retaining agent, light aggregate and the like. "a method for producing color pattern ECP assembled wallboard by using phosphogypsum" (CN 110092631A) provides a method for producing color pattern ECP assembled wallboard by using phosphogypsum and a preparation method thereof, wherein the wallboard simultaneously uses phosphogypsum and cement as cementing materials, and sand and ceramsite as aggregates. "an interface enhancement ardealite light inner wall baffle and its preparation method (CN 110194641A)" provides an interface enhancement ardealite light inner wall baffle and its preparation method, also uses ardealite and cement as cementing material, in addition adopts core-shell structure foaming polystyrene as light aggregate.
But from the viewpoints of light weight, high strength, attractive appearance, energy conservation, environmental protection and economy, the formula of the phosphogypsum-based inner partition board can be continuously developed. In addition, when the wallboard is large in size, the mechanical property requirements in the transportation and installation processes are often difficult to meet due to limited material strength, particularly the longitudinal bending resistance, and therefore, the reinforcing ribs can be considered for the wallboard. "a double circular arc protruding stone-plastic interior wallboard with wood rib" (CN 110056122A) proposed a double circular arc protruding stone-plastic interior wallboard with wood rib, but considering the material source, it is more suitable to use bamboo as the rib. "a bamboo wood fiber wallboard easy to install and manufacturing method thereof" (CN 110107017A) proposed a wallboard comprising bamboo wood fiber board, and the fiber board processed from bamboo is used as a reinforcing material, and there is also room for improvement.

The method comprises the steps of selecting tubular straight bamboos with the average diameter of 10-30 mm as bamboo reinforcing ribs, and determining the number of the required bamboo reinforcing ribs 1 according to the design width of the wall board. If the wallboard width is 0.6m, bamboo strengthening rib 1's interval is between 100mm ~200mm, and is optional 150mm, then every layer can set up 4 bamboo strengthening ribs 1, and upper and lower two-layer needs 8 bamboo strengthening ribs 1 altogether.
The length of the bamboo reinforcing rib 1 is determined according to the design length of the wall board. If the length of the wall board is 3m, the length of the bamboo reinforcing rib 1 is 3m- (100 mm-160 mm) =2.84 m-2.90 m, and 2.86m can be selected, and the distance from the end part of the bamboo reinforcing rib 1 to the longitudinal edge of the wall board is (3 m-2.86 m)/2 =0.07 m.
The distance between two-layer bamboo strengthening rib 1 is confirmed according to the design thickness of wallboard. If the thickness of the wall board is 120mm, the distance between the outer side surfaces of the two layers of bamboo reinforcing ribs 1 is 120mm-2 (20 mm-40 mm) =40 mm-80 mm, and 70mm can be selected. At this time, the distance from the outer edge of the bamboo reinforcing rib 1 to the nearest outer surface of the wall panel was (120 mm-70 mm)/2 =25 mm.
Then the 8 bamboo reinforcing ribs 1 are bound and connected into a whole by using galvanized iron wires 2 according to the above intervals, so that the fixation of the relative positions is realized, and a reinforcing rib cage is formed.
