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

Embodiment Construction

[0028] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0029] See figure 1 , including rigid tube 1 (see Figure 4 ), airbag 6 (see Figure 5 ), barometer 5, force plate 3 (see Image 6 ), screw cap 2 (see Figure 7 ). The specific arrangement is to place the air bag 6 longitudinally along the rigid pipe 1 axially, make the position of the air bag inflation valve correspond to the position of the reserved inflation hole on the pipe wall of the rigid pipe 1 and fix the inflation valve, and the air gauge 5 is installed on the rigid pipe wall reserved Next to the communication hole and communicated with the air bag, two force-supporting plates 3 are respectively placed at both ends of the rigid pipe 1, and then two screw caps 2 are tightly connected with the two ends of the rigid pipe 1 through threads.

[0030] The rigid tube is a hollow circular tube with high material strength, and the outer walls at both ends m...

Abstract

The invention relates to a rigid wall air-supported axis compression rod piece. The rigid wall air-supported axis compression rod piece comprises a rigid pipe, an air bag, an air pressure gauge, force maintaining plates and thread caps; an air bag inflating hole and an air pressure gauge communicating hole are reserved in the pipe wall of the rigid pipe; the air bag is placed in the axial direction of the interior of the rigid pipe; the air pressure gauge is mounted at the communicating hole which is reserved in the pipe wall of the rigid pipe and is communicated with the air bag; the force maintaining plates are positioned at the two ends of the air bag and are internally tangent to the inner wall of the rigid pipe; the thread caps are respectively in threaded connection with the two ends of the rigid pipe. When the rigid wall air-supported axis compression rod piece is in a normal working state, the rigid wall of the rod piece does not bear pressure; the axial pressure is completely borne through the air bag, and is converted into circumferential tensile stress of the rigid wall, so that the axial compressive bearing capacity of the rod piece is improved, and the tensile strength of a rigid wall material can be fully utilized to achieve the purposes of light weight and high strength. The rigid wall air-supported axis compression rod piece is simple in structural form, safe and economical, and has a good market application prospect.

Description

technical field [0001] The invention belongs to the field of components in engineering structures, and in particular relates to a rigid-wall air-bearing axial-center 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. Usually, the rods in the structure are mainly subjected to axial force, and when the hinge joint is used, the member only bears the axial force. For tension rods, the tensile bearing capacity of the rods can be improved by using high-strength materials, while the bearing capacity of compression rods is controlled by stability, and the strength of materials has little effect on the bearing capacity of compression rods. big. Due to the limitation of slenderness ratio, compression me...
