Problems solved by technology

Due to the limitation of the slenderness ratio, the compression members cannot transmit the pressure of a long distance well. In addition, this also limits the application of high-strength materials in the space grid structure

Abstract

The invention relates to a rigid wall airbag pressure-bearing eccentric compression rod piece. Three fan-shaped rigid pipes are installed in a circular rigid pipe, a fan-shaped airbag is installed in each fan-shaped rigid pipe, and fan-shaped force-holding plates are installed at the two ends of each fan-shaped rigid pipe; joint outlets used for installing a feeding valve and a barometer are formed in each fan-shaped airbag, the feeding valve and the barometer are connected with the fan-shaped airbags through airbag feeding holes formed in the circular rigid pipe and the barometer joint outlets formed in the fan-shaped rigid pipes correspondingly, and the two ends of the circular rigid pipe are connected with a threaded cap in a thread mode; and circular force-holding plates are installed in the threaded cap, and force transferring rods are installed between the circular force-holding plates and the fan-shaped force-holding plates. According to the rigid wall airbag pressure-bearing eccentric compression rod piece, through air bag pressure bearing, the eccentric pressure of the eccentric compression rod piece is transformed into rigid-wall tensile stress, and the tensile degree of rigid-wall materials is sufficiently used, so that a rigid wall of the eccentric compression rod piece does not bear the pressure stress, and eccentric compression stability of the rod piece is improved.

Description

technical field [0001] The invention belongs to the field of components in engineering structures, and relates to a rigid wall air bearing eccentric compression rod. Background technique [0002] Spatial grid structures such as grid frames and reticulated shells are widely used in stadiums, railway stations, terminal buildings and some special structures. The spatial grid structure is composed of rigid members of different lengths according to a certain topological relationship. The rods in the actual structure are usually mainly subjected to axial force and bear a certain bending moment at the same time, that is, the rod in the spatial grid structure is an eccentric compression or eccentric tension rod. For eccentric tension rods, the tensile bearing capacity of the rods can be improved by using high-strength materials, while the bearing capacity of eccentric compression rods is controlled by stability, and the strength of materials is very important for improving the stre...
