Novel lightweight environment-friendly pedal of scaffold for building, and production process thereof

Abstract

The invention relates to a novel lightweight environment-friendly pedal of a scaffold for building. The pedal comprises a board, a top skin, a polypropylene honeycomb core material, a bottom skin, anda finished board, wherein the board is of a three-layer sandwich structure; the top skin and the bottom skin are both prepared by compounding multiple layers of continuous glass fiber polypropylene reinforced unidirectional prepreg tape; the pure polypropylene honeycomb core material is arranged at the center; and the skin of the continuous glass fiber polypropylene reinforced unidirectional prepreg tape is prepared polypropylene and continuous glass fibers through compounding, and the skin with a thickness of 0.6 to 2.0 mm and the pure polypropylene honeycomb core are subjected to hot-melting bonding on the finished board. The novel surface layer reinforcing material, i.e., the continuous glass fiber polypropylene reinforced unidirectional prepreg tape, is utilized in the invention, andhas strength and other properties several times better than those of short fiber felt or long fiber composite materials, and the high performance leads to reduction in used materials; i.e., under thecondition of same physical properties, the pedal using the continuous glass fiber polypropylene reinforced unidirectional prepreg tape saves more materials and is reduced in material cost.

Description

Technical field [0001] The invention relates to the technical field of building board production, in particular to a new type of lightweight environmental protection building scaffold pedaling and production process. Background technique [0002] The existing domestic building scaffolding generally use moso bamboo or bamboo plywood to step on, but there are many defects in the process of use. One is the general bending strength and the sheet is soft, which poses certain safety risks; the other is the short service life, which causes The use cost is high; thirdly, it is not environmentally friendly due to factors such as the use of biological materials, the addition of chemical substances such as glue, and the short replacement cycle. Later, some companies developed steel plates, steel mesh sheets, aluminum sheets and other materials to replace the previous bamboo sheets or bamboo plywood, but there are still many problems, such as the increase in unit weight, resulting in increas...

AI Technical Summary

Problems solved by technology

[0002] The pedals of existing domestic construction scaffolds generally use moso bamboo or bamboo plywood, but there are many defects in the use process. First, the bending strength is average, and the board is soft, which has certain potential safety hazards; The use cost is high; the third is that it is not environmentally friendly due to the use of biological materials, the addition of chemical substances such as glue, and the short replacement cycle.

Later, some companies developed materials such as steel plates, steel fence sheets, and aluminum sheets to replace the previous moso bamboo sheets or bamboo plywood, but there are still many problems, such as the increase in unit weight, which increases the labor intensity of workers; and the service life is limited. It has been improved, but the production cost is also increasing significantly, and the final cost performance is not high
