Large-span bamboo truss structure roof with heat insulation function and construction process thereof

Abstract

The invention relates to a large-span bamboo truss structure roof with a heat insulation function and a construction process thereof. The large-span bamboo truss structure roof comprises a plurality of trusses, wherein each truss consists of chord rods and web rods; the chord rods comprise an arc-shaped upper chord rod and an arc-shaped lower chord rod; the two ends of the upper chord rod and the lower chord rod are mutually connected to form an oval shape; the web rods comprise a plurality of straight-rod-shaped vertical web rods and inclined web rods; the vertical web rods are vertically arranged between the upper chord rod and the lower chord rod ; one inclined web rod is arranged between every two vertical web rods, so that each vertical web rod and each inclined web rod form a triangular shape with the upper chord rod or the lower chord rod; a plurality of purlines connected between the upper chord rods are arranged between every two trusses; a heat insulation layer is arranged above the purlines; a color plate and ceramic tiles are laid on the heat insulation layer. The large-span bamboo truss structure roof has the advantages that the span requirements can be met; in addition, the load bearing capability of the roof can be improved; the deflexion of the roof is small, so the use space is greatly improved. Meanwhile, the heat insulation and thermal isolation performance is good; the durability is high; the energy is saved and the environment is protected.

Description

technical field [0001] The invention relates to a building component, in particular to a large-span bamboo truss structure roof made of bamboo and having a thermal insulation function, specifically a large-span bamboo truss structure roof with thermal insulation function. [0002] The present invention also relates to a construction process of the above-mentioned large-span bamboo truss structure roof with thermal insulation function. Background technique [0003] At present, with the development of long-span bamboo and wood structures, the span of buildings is gradually increasing, and the load acting on the roof is also increasing. Due to the low tensile bearing capacity of bamboo girders, the cross-section of bamboo girders needs to be increased. Bamboo girders with large spans and large cross-sections not only lead to a larger self-weight of the beam body, but also the bearing capacity cannot meet the requirements of design and use; The deflection under the large upper ...

Problems solved by technology

Due to the low tensile bearing capacity of bamboo girders, the cross-section of bamboo girders needs to be increased. Bamboo girders with large spans and large cross-sections not only lead to a larger self-weight of the beam body, but also the bearing capacity cannot meet the requirements of design and use; The deflection under the large upper load is also relatively large, which cannot meet the requirements of use; the bamboo beams with large spans and large sizes cannot make full use of materials, especially near the support, which will cause a lot of waste of materials and fail to meet the economic requirements. requirements

[0004] With the increasingly serious environmental problems, the concept of energy saving and environmental protection plays an important role in the construction. The thermal conductivity of the roofs currently used is relatively large, which is very unfavorable to indoor energy saving. Therefore, it is necessary to design a bamboo , and a roof system with good thermal insulation performance
