Problems solved by technology

[0004] From the above, it can be seen that flexible air beams and air pillows have insufficient bearing capacity and are only suitable for self-supporting structures. Structural members based on the concept of air-supported tensioned string structures have a large bearing capacity, but they have to rely on stiff compression units to increase its carrying capacity

Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiment:

[0029] The structure and construction of inflatable membrane struts, such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the production sequence is as follows:

[0030] 1) Cut the membrane material into a rectangle to make the tubular airbag 2, one side of the rectangle is parallel to the meridian direction of the membrane material and used in the circumferential direction of the tubular airbag 2, and the other side is parallel to the weft direction of the membrane material and used in the axial direction of the tubular airbag 2.

[0031] 2) On both sides of the rectangular membrane material, two 150-200mm wide reinforcing membrane materials 3 are arranged along the warp direction by high-frequency welding.

[0032] 3) Two balance ribs 7 are arranged on the inner wall of the membrane material by high-frequency welding.

[0033] 4) The membrane m...

Abstract

The invention discloses a pneumatic membrane compression bar and a manufacturing method thereof and belongs to the field of pneumatic membrane structures. The pneumatic membrane compression bar comprises a bar end enclosure (1), a tubular air bag (2), reinforcing membrane materials (3), a sealing rubber ring (4), buried ropes (5), a thermal bonding seam rib (6), a balancing rib (7), an air inlet (8), an air outlet (9), a bar end steel hoop (10) and a sealing rubber pad (11). The pneumatic membrane compression bar is characterized in that a membrane material and the thermal bonding seam rib (6) are connected to form the tubular air bag (2), and meanwhile, the tubular air bag (2) is internally provided with the balancing rib (7); the inner walls at two ends of the air bag are additionally provided with the reinforcing membrane materials (3), and the buried ropes (5) are embedded in the ends of the air bag; and the tubular air bag (2) is connected with the bar end enclosure (1) by using the bar end steel hoop (10), and meanwhile, construction measures including the sealing rubber ring (4), the sealing rubber pad (11) and the buried ropes (5) are adopted between the tubular air bag (2) and the bar end enclosure (1) so that the pneumatic membrane compression bar is assembled. The pneumatic membrane compression bar has the characteristics of high compression resistant rigidity, light weight, high bearing capability and convenience in deformation compatibility, manufacture and installation.

Description

technical field [0001] The invention relates to a rod, which can be applied to a pressure rod in structures such as trusses, in particular to an airbag-type inflatable membrane pressure rod made of architectural membrane materials, which belongs to the technical field of membrane structures. Background technique [0002] The development of inflatable membrane structure is relatively late in our country, and the theoretical analysis and engineering practice have lagged behind foreign countries for a long period of time. Tongji University was the first to conduct research on inflatable membranes. In 1980, it built an exhibition hall of air-supported membrane structures in Shanghai Industrial Exhibition Hall, which was an attempt to apply inflatable membrane structures in my country. Subsequently, Chinese scholars did a lot of research work, and the airbag membrane structure mainly focused on the research of air beams, air arches and air pillows. On the premise of introducing f...
