Problems solved by technology

And the internal pressure of the airbag is low pressure, which also limits the improvement of its bearing capacity
[0006] Li Yugang and others invented the rigid-walled air-bearing axial compression rods and eccentric compression rods, using air as the pressure material, and using rigid tubes to confine the gas, but this series of inventions is limited to axial compression rods and bias pressure rods. It cannot be applied to the stress situation of more common components, and it is difficult to apply high-strength materials such as prestressed steel to the material of the rigid pipe part

Embodiment 1

[0065] Such as figure 1 As shown, the prestressed reinforced membrane structure in this embodiment consists of a capsule 1 , a flexible reinforced skeleton 2 , an annular rigid member 3 , and a connector 5 . The capsule body 1 is an ellipsoid, or a curved surface of revolution whose generatrix is ​​a parabola. The capsule body is a membrane structure with more than one layer, and the annular rigid member can be made of steel or other high-strength materials. The inner side of the annular rigid member 3 is circular so as to match the outer wall of the capsule 1 . The flexible reinforced skeleton 2 adopts high-strength cable materials such as prestressed steel strands or FRP; The principal stress line of the capsule changes, and ring-shaped rigid members are arranged at both ends of the capsule from the point where the included angle changes to zero, and the included angle does not change anymore; an annular rigid member can also be installed in the middle of the capsule to fa...

Embodiment 2

[0070] Such as Figure 10 As shown, the difference between this embodiment and the first embodiment is that the structure body in this embodiment adopts a cylindrical capsule with a cylindrical middle part and hemispherical ends. A pulley 3.1 is welded on the ring-shaped rigid member 3, and the helically wound flexible cable bypasses the pulley and changes its direction to be arranged along the plain lines at both ends of the capsule body; beam structure such as Figure 10 , continuous beam such as Figure 11 or a cantilever beam structure such as Figure 12 .

[0071]The flexible cable in this embodiment can be replaced by fiber cloth, and the fiber cloth is densely spread on the surface of the capsule body, and the laying direction is the same as that of the above-mentioned flexible cable. The fiber cloth is firmly glued at the joints and the spherical areas at both ends, and the contact surface between the fiber cloth arranged along the capsule element line and the spir...

Embodiment 3

[0073] Such as Figure 13 As shown, the difference between this embodiment and the second embodiment is that the capsule 1 used in the structure in this embodiment is an annular capsule, and the anchor 4 is arranged on a ring-shaped rigid member sleeved outside the capsule. , the connector 5 is welded with the annular rigid member 3, the angle between the interlaced winding cable 2.1.1 and the plain line of the formed capsule is constant, refer to the angle of the principal stress line after the capsule is formed; complete the arrangement of the flexible reinforced skeleton 2 Finally, the capsule is inflated, and the prestress of the flexible cable or fiber cloth is established. The structure shown in the figure can be used as a bicycle rim, which can reduce the weight of the vehicle.

[0074] The capsule in this embodiment can also be replaced by a semi-annular capsule or a curved capsule with varying curvature, and the flexible reinforced skeleton at both ends is connected w...

Abstract

The invention discloses a prestressed reinforced membrane structural body and a combined type prestressed reinforced membrane structural body. The prestressed reinforced membrane structural body comprises a capsule body, a flexible reinforced framework and annular rigid components, wherein the content of the capsule body is a fluid, the annular rigid components are correspondingly arranged at theperiphery of the corresponding end parts of the capsule body, the flexible reinforced framework is arranged outside the capsule body, when the flexible reinforced framework comprises flexible cables,the flexible cables are arranged along the direction of a plain wire or a lead of the capsule body, or is wound around the periphery of the capsule body in a staggered manner, or is arranged in a mixed mode of the plain wire and the lead, the intersection points of the flexible cables arranged along the plain wire of the capsule body and the flexible cables wound around the periphery of the capsule body in the staggered mode are connected by using nodes capable of transmitting force, and the outline size of the capsule body filled with the fluid is larger than the outline size of the flexiblereinforced framework formed by the flexible cables, and when the flexible reinforced framework comprises flexible fiber cloth, the fiber cloth completely wraps around the capsule body. The prestressedreinforced membrane structural body and the combined type prestressed reinforced membrane structural body have the advantages of being light in weight, portable, convenient to install and uninstall,high in bearing capacity and rigidity and high in impact-resistant strength.

Description

technical field [0001] The invention relates to a load-bearing elongated structural member, in particular to a prestressed reinforced membrane structure and a combined prestressed reinforced membrane structure. Background technique [0002] In structural engineering, elongated structural members are mainly made of concrete, steel, wood and other materials and combinations thereof. Among them, the beam member will produce compression area and tension area under the load. In order to make full use of the characteristics of the material and reduce the self-weight, reinforced concrete beams, steel-concrete composite beams and wood-concrete beams can be used; in order to further reduce the self-weight and save materials , T-shaped beams, box girders and other cross-sectional forms can be used, and beams with web openings can also be used. [0003] However, as the span increases, the load effect caused by the self-weight of the structure increases significantly. Therefore, the ab...
