Circular bamboo space three-hinged arch structural unit and circular bamboo space three-hinged arch structural system

Abstract

Disclosed are a circular bamboo space three-hinged arch structural unit and a circular bamboo space three-hinged arch structural system. The circular bamboo space three-hinged arch structural unit comprises a fixing device, a first space unit and a second space unit, wherein the first space unit and the second space unit jointly consist of vertical supporting structures and roof bearing structures. The top ends of the first space unit and the second space unit are hinged together and hinged to the fixing device at the bottom ends of the first space unit and the second space unit to form the space three-hinged arch unit. The circular bamboo space three-hinged arch structural system comprises the circular bamboo space three-hinged arch structural unit. A certain distance exists between two adjacent circular bamboo space three-hinged arch structural units. A connecting device used for connecting the every two adjacent circular bamboo space three-hinged arch structural units into a whole is arranged between every two adjacent circular bamboo space three-hinged arch structural units. According to the circular bamboo space three-hinged arch structural unit and the circular bamboo space three-hinged arch structural system, the section bending moment of a single rod part of a structure system is very small, rod parts mainly bear the axial force, and while the circular bamboo rod partsare poor in flexural performance but good in axial force, so the circular bamboo space three-hinged arch structural unit and the circular bamboo space three-hinged arch structural system are suitablefor a circular bamboo structure.

Description

technical field [0001] The invention belongs to building structures, in particular to a round bamboo space three-hinge arch structure unit and a round bamboo space three-hinge arch structure system. Background technique [0002] The truss roof truss is a planar structure composed of straight rods and generally has triangular units. The truss rods mainly bear axial tension or pressure, so that the strength of the material can be fully utilized, and it is widely used in life and industry. However, due to the setting of the lower chord members, the "triangular" space occupied by the truss roof truss cannot pass through. The effective passage and use height of the building is the height from the lower chord to the ground, which greatly affects the passing height of the building.

The round bamboo structural columns are arranged obliquely and meet at a point where the roof eav...

However, due to the setting of the lower chord, the "triangular" space occupied by the truss roof truss cannot pass through, and the effective passage and use height of the building is the height from the lower chord to the ground, which greatly affects the passing height of the building

[0003] In the 2010 Shanghai World Expo, the "German-Chinese Home" is a round bamboo structure building. The round bamboo structural columns are arranged obliquely and meet at a point where the roof eaves and the ground meet. The access to the building is the angled space between the round bamboo structural columns. , the effective passageway for people is small, and the rapid evacuation of the flow of people cannot be realized. In order to increase the passageway into the building, the angle between the columns of the round bamboo structure can be increased or the height of the building can be increased, but both will bring As the length of the round bamboo column increases, the structural stability becomes worse, so this structure is not suitable for buildings with a large flow of people

The structure uses steel members to bear the roof load, and the steel members transmit the roof load to the connecting nodes of the round bamboo in the form of node load. The round bamboo bars on the roof only serve as a connection, and do not bear the vertical load of the roof, which is wasteful

The connecting members between the roof structural units are only horizontal and vertical rods, no triangles are formed, and the overall stability of the roof is poor
