Abstract

The invention belongs to the technical field of construction and relates to a rapid construction method for a truss with a pneumatic membrane compression bar. The method for the truss with the pneumatic membrane compression bar comprises the following steps that: 1, the length of a pre-stress inhaul cable of the truss is determined in a machining factory and installation and adjustment allowance is reserved; 2, arrangement of support seat foundation and base is completed at a construction site; 3, 50KPa to 70KPa interior air pressure is inflated in an air bag of the pneumatic membrane compression bar; 4, two trusses are assembled; 5, a next truss is arranged in a spliced mode based on the two existing trusses; 6, more trusses are installed through the method of step 5 until assembly in the spliced mode of a whole truss structure is completed; 7, post construction tasks of the whole truss structure are completed with an installed truss structure as a working face; and 8, an air inflating device is connected with the air bag of the pneumatic membrane compression bar so that all construction of the whole truss structure is finished. The method for the truss with the pneumatic membrane compression bar is simple in steps, low in cost, capable of achieving construction without a scaffold and with construction devices in small number, applicable to the condition that the pneumatic membrane truss structure serves as a temporary structure and significant to earthquake relief work and rebuilding work after an earthquake.

Description

technical field [0001] The invention relates to a rapid construction method suitable for a truss with an inflatable membrane compression bar, especially suitable for the rapid construction of a truss with an inflatable membrane compression bar under limited construction conditions, especially suitable for earthquake resistance or post-disaster reconstruction. Background technique [0002] In recent years, large natural disasters have occurred continuously, which have caused huge losses to the national economy and also brought great harm to people's lives and health. Several major earthquakes, such as the Wenchuan earthquake and the Yushu earthquake in Qinghai, fully exposed the lack of research and engineering application of temporary buildings and bridges in my country. [0003] Among the patents that have been declared, the patent application number [201210520746.6] discloses a truss system with an inflatable membrane strut, and the patent application number [201210521380....
