Abstract

The invention discloses a multi-layer and multi-span raw bamboo stair which comprises a plurality of layers of step plates and a plurality of rest platforms connected to the step plates. The step plate comprises a plurality of steps and C-shaped steel I; and a plurality of transverse raw bamboo rod pieces of the ladder steps are connected through transverse bolts. One end of the transverse raw bamboo rod piece is connected to a building main body structure, and transverse C-shaped steel and vertical C-shaped steel are installed at the other end of the transverse raw bamboo rod piece. The transverse C-shaped steel and the vertical C-shaped steel are fixedly connected into the C-shaped steel I. The lower end of the C-shaped steel I of the first layer of step plate is connected with the ground, and the upper end of the C-shaped steel I of the first layer of step plate is connected with the corresponding rest platform. The upper end and the lower end of the C-shaped steel I located above the first layer of step plate are connected with the corresponding rest platforms respectively. According to the structure, the raw bamboo rod pieces with the light weight are adopted as raw materials, carrying and assembling are convenient, flexible installation on the construction site can be achieved, and the problems that a traditional prefabricated floor slab is high in transportation cost, inflexible in site installation and the like are solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a multi-layer and multi-span original bamboo staircase. Background technique [0002] Most of the existing stairs are made of concrete or wood. Among them, the weight of the concrete structure is heavy and the cost is high. However, due to the long growth period of the wood, the wood stairs cause great damage to the environment. The heavier the weight, the less stable the stairs. Under the general trend of global energy conservation and environmental protection, bamboo has been widely used in building structures due to its characteristics of easy reproduction, fast growth, early maturity and high output, especially in some earthquake-prone areas or tourist areas, so it is necessary to design A kind of original bamboo staircase is developed to improve the safety and reliability of the staircase. Contents of the invention [0003] The purpose of the present invention is to ...
