Example Embodiment
[0016] Example 1:
[0017] Please refer to the accompanying drawings, which shows a board body 1 made of a cementitious material, specifically β-type hemihydrate gypsum, magnesium oxide, sodium silicate aqueous solution, and inorganic foam plastic and sawdust in a weight percentage of 1:0.5 It is made of mixed fillers. In this embodiment, although it is shown that the mesh cloth 2, which is preferably made of glass fiber, has one layer on the upper and lower surfaces of the board body 1, two layers are not excluded. For example, two layers are placed on the upper and lower surfaces of the board body 1. Layer mesh cloth 2, or lay two layers on the upper surface of the board body 1, and lay one layer on the lower surface of the board body 1, and vice versa. The shape of the plate hole 11 formed on the plate body 1 is preferably, but not limited to, a circular hole. The reinforcing strips 3, which are made of bamboo and have a rectangular cross-sectional shape, are interposed b...
Example Embodiment
[0018] Example 2:
[0019] Only the shape of the plate hole 11 is changed into a triangle, the cross-sectional shape of the bamboo wattle is changed into a circle, the gypsum is α-type gypsum, and the mixing ratio (weight percent) of the inorganic foam material and the sawdust is changed to 1:0.8, The rest are the same as those described in Embodiment 1.
Example Embodiment
[0020] Example 3:
[0021] Only change the shape of the plate hole 11 to hexagon, change the cross-sectional shape of bamboo wattle to triangle, change the mixing ratio (weight percent) of inorganic foam plastic and sawdust to 1:1, and the rest are the same as those of Example 1. describe.
[0022] Production example 1:
[0023] First, one or two layers of mesh cloth made of glass fiber are laid on the floor of the processing site, and then the ratio by weight is gypsum:magnesium oxide:sodium silicate aqueous solution:filler:additive=1:1~2: 0.8~1:1.5:0.02 of the mixed cementitious material is placed on the mesh cloth 2, and the sticks for forming the plate holes 11 are inserted into the cementitious material and the reinforcing strips 3 are inserted into the cementitious material at a certain interval. In the material, the preferred distribution of the reinforcing strips 3 is between two adjacent sticks, and finally one or two layers of mesh cloth 2, which are also made of g...
