Description

Device for testing compressive strength and pull-out strength of bolt for fiber cement board Technical Field The utility model relates to a device for detecting the compressive strength and the pulling-out strength of a fiber cement board/calcium silicate board bolt, belongs to the field of concrete material testing, and particularly relates to a device for detecting the compressive pulling-out strength of a fiber cement board bolt. Background The fiber cement board is a novel building material, has the advantages of water resistance, fire resistance, sound insulation, heat preservation and the like, and is widely applied to the fields of building, decoration, ground, wall, ceilings and the like. Traditional fiber cement wallboard mounting mode is rivet fixed, has easily to crack the board, and not pleasing to the eye scheduling problem inadequately. The novel fiber cement board mounting mode is that expansion bolts are fixed, and the expansion bolts are mounted on the back of the board and cannot penetrate through the wallboard. However, on the market, the bolt pulling-out test device for the expansion bolts of the traditional fiber cement wallboard or the novel fiber cement wallboard is relatively simple, the breaking load of the bolts can be tested, and the pressing-down test can not be performed.
