Problems solved by technology

Although the several types of roof panels mentioned above have their own advantages, they are likely to be cracked to varying degrees, that is to say, they cannot show a satisfactory level of strength.
Although CN2213772Y uses a steel wire grid to make up for the strength problem, because the metal material is easy to corrode, it increases the fragility of the board to a certain extent

Embodiment 1

[0017] Please refer to the accompanying drawings, which shows a plate body 1 made of cementitious materials, specifically, it is composed of β-type hemihydrate gypsum, magnesium oxide, sodium silicate aqueous solution and inorganic foam plastics and sawdust in a weight percentage of 1:0.5 It is made of mixed filling materials. In this embodiment, although it is illustrated that the mesh cloth 2 whose material is preferably glass fiber has one layer on the upper and lower surfaces of the board body 1, it does not exclude two layers, for example, two layers are placed on the upper and lower surfaces of the board body 1. One layer of mesh cloth 2, or two layers are laid on the upper surface of the board body 1, and one layer is laid on the lower surface of the board body 1, and vice versa. The preferred but not limited shape of the plate hole 11 formed on the plate body 1 is a circular hole. Reinforcing strips 3 made of bamboo wattle and rectangular in cross-section are interpos...

Embodiment 2

[0019] Only the shape of the plate hole 11 is changed into a triangle, the cross-sectional shape of the bamboo vitex is changed into a circle, the gypsum is adopted as α-type gypsum, and the mixing ratio (percentage by weight) of the inorganic foam material and sawdust is changed to 1:0.8, All the other are the same as the description of embodiment 1.

Embodiment 3

[0021] Only change the shape of the plate hole 11 into a hexagonal shape, change the cross-sectional shape of the bamboo jingle into a triangle, change the mixing ratio (percentage by weight) of inorganic foamed plastics and sawdust into 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 weight ratio is gypsum: magnesium oxide: sodium silicate aqueous solution: filler: additive = 1: 1 ~ 2: The gelling material mixed at 0.8~1:1.5:0.02 is placed on the mesh cloth 2, and the sticks used to form the plate holes 11 are inserted into the gelling material and the reinforcing strip 3 is inserted into the gelling material at a certain distance. In the material, the preferred distribution of the reinforcing strip 3 is between two adjacent sticks, and finally one or two layers of mesh cloth 2, which is also made of gl...

Abstract

A roof boarding of light weight, high strength and fireproof is provided, which belongs to the technology field of building material. The roof boarding comprises a boarding body, boarding holes provided at intervals in the interlayer in a length direction of the boarding body and at least one layer of net cloth combining with the upper and the lower surfaces of the boarding body. The roof boarding is characterized in that non-metal reinforcing bars used for increasing the strength of the boarding body are further arranged in the interlayer in the length direction of the boarding body. The roof boarding has the advantage that the non-metal reinforcing bars used for increasing the strength of the boarding body are added in the interlayer in the length direction of the boarding body, thereby avoiding cracking when in use.

Description

technical field [0001] The invention relates to a lightweight and high-strength fireproof roof base material, which belongs to the technical field of building materials. Background technique [0002] In documents such as Chinese patent documents, there is no shortage of technical solutions for roofing substrates, such as the glass fiber magnesium hollow insulation board disclosed by CN2339654Y, the board body made of expanded perlite, lightly burned magnesium, and bittern, and the middle layer of the board body. There are multiple horizontal and longitudinal cylindrical holes, and the upper and lower surfaces of the board are combined with glass fiber cloth; the magnesium-silicon fiber-planting composite lightweight hollow wallboard introduced by the publication number CN1101092A, the board body is made of magnesia, industrial waste residue, and plant fiber. , glass fiber, magnesium chloride, additives A, B and C, flanges and concave edges are respectively arranged on both s...
