The invention provides a bamboo-wood structure folding suspension ladder, and aims to enable a staircase matched with a wood structure building to be firm, attractive, exquisite, convenient and fast to operate and meet the fireproof requirement.
In order to achieve the purpose, the invention provides a bamboo-wood structure folding suspension ladder which comprises a folding suspension unit, ladder steps and handrails. The bamboo-wood structure folding suspension ladder is characterized in that a plurality of adjusting connecting pieces on the folding suspension units are suspended on connecting steel sheets on a truss girder of a roof plate, and the ladder steps are fixed among handrails, wall panels and ladder inclined beams to form a single-side suspended single running ladder.
The scheme of the invention has the following beneficial effects.
The folding type hanging unit of the invention connects the connecting plate and the railing through the bolt to form the folding tension member, and the folding type hanging unit can be folded and packed separately after being preassembled in factory production, thereby saving the storage and transportation space.
According to the bamboo-wood structure folding suspension ladder, the form of a wood structure ladder is added, the stress components of the ladder are all tensile components, the recombined bamboo with the cross section of 100mm multiplied by 20mm can meet the stress requirement, the recombined bamboo is a B1-grade fireproof material, the fireproof requirement is met, and the fireproof problem of the wood structure building ladder is solved.
According to the bamboo-wood structure folding suspension ladder, the folding suspension units are classified and pre-assembled in advance in a factory, and only need to be unfolded and fixed on the site, so that a large amount of construction cost is saved.
According to the bamboo-wood structure folding suspension ladder, the stress of the ladder is transmitted to the roof plate truss girder through the folding suspension unit, and the noise generated by the resonance of the ladder and a wall body is reduced.
