Description

Technical Field

[0001] The utility model relates to the technical field of air membrane buildings, in particular to an air rib membrane structure with a lifting device. Background Art

[0002] The inflatable structure of an air-supported building, also known as an "inflatable membrane structure," is a structure formed by filling a thin polymer film with air. Inflatable structures can be further divided into air-supported membrane structures and air-expanded membrane structures (also called air-ribbed membrane structures).

[0003] During the construction of large-volume concrete, air-ribbed membrane structures are often used to insulate the concrete. However, as the height of the large-volume concrete increases, the air-ribbed membrane structure covering the large-volume concrete needs to be frequently lifted. That is, the air-ribbed membrane structure needs to be removed before pouring a new layer of concrete and then reinstalled after pouring is completed. This lifting process is cumbersome, time-consuming, and labor-intensive, increasing construction costs and affecting the construction progress of the large-volume concrete. Utility Model Content

The present invention provides an air-ribbed membrane structure with a lifting device, which has the advantages of being able to lift the air-ribbed membrane structure without disassembling the air-ribbed membrane structure, simplifying the construction process, reducing construction costs, and accelerating the construction accuracy of large-volume concrete.

[0016] The truss support seat provided on the lifting column is used to support the truss support beam after the height is raised, so that the truss support beam after the height is raised remains stable.

[0017] Optionally, the truss support seat includes a vertical plate rotatably mounted on a lifting column or a supporting column and a horizontal plate fixed on the vertical plate. The vertical plate can be rotated toward a side close to the truss support beam so that the horizontal plate can be rotated to the bottom of the truss support beam and support the truss support beam.

[0034] This embodiment relates to an air rib membrane structure with a lifting device, which is covered on a large volume of concrete to insulate the large volume of concrete 100. Figures 1-6 , including an air rib membrane main body 10, a truss support beam 20 and a truss lifting device 30. The air rib membrane main body 10 has an inflated form and a deflated form. When the air rib membrane main body 10 needs to be lifted, the air rib membrane main body 10 needs to be deflated to convert it from an inflated form to a deflated form, and then the height of the air rib membrane main body 10 is lifted by the truss lifting device 30.

[0035] The truss support beam 20 is provided on the bottom side of the air rib membrane body 10, and is used to support the air rib membrane body 10. The truss lifting device 30 includes a plurality of lifting columns 31 evenly distributed on the outer edge of the truss support beam 20 and a driving member provided on the lifting column 31 for driving the truss support beam 20 to vertically rise and fall along the length direction of the lifting column 31. Among them, the bottom end of the lifting column 31 is fixed to the large volume concrete 100 by bolts, that is, the lifting column 31 is detachable. After the height of the air rib membrane structure is raised, the lifting column 31 can be removed for reuse. The number of driving members is several, and the several driving members correspond one to one to the several lifting columns 31, and the several driving members synchronously drive the truss support beam 20 to vertically rise and fall along the length direction of the lifting column 31.

[0036] When it is necessary to raise the height of the air rib membrane body 10, the air rib membrane body 10 is first deflated to convert the air rib membrane body 10 from an inflated state to a ventilation state. At this time, the truss support beam 20 is driven by the driving member to rise vertically along the length direction of the lifting column 31, so that the air rib membrane body 10 in the deflated state is lifted to a certain height, thereby achieving the height increase of the air rib membrane body 10.

[0037] In this embodiment, the driving element comprises a hoist 32 fixedly mounted on the top of the lifting column 31. The wire rope of the hoist 32 extends downward and is fixedly connected to the truss support beam 20. Generally, a hook is provided at the end of the wire rope of the hoist 32. By hooking and fixing the hook to the truss support beam 20, the hoist 32 is driven to drive the truss support beam 20 vertically upward along the length of the lifting column 31. In other embodiments, the driving element may also be configured as a chain motor structure, a screw motor structure, etc., and this is not limited here.

[0038] Several support columns 40 are evenly distributed on the underside of the truss support beam 20, each supporting the truss support beam 20. Each support column 40 is located between two lifting columns 31. The arrangement of the support columns 40 allows the air rib membrane structure to maintain a certain height, thereby facilitating thermal insulation of the large volume of concrete 100. Furthermore, the placement of the support columns 40 between the two lifting columns 31 allows the multiple support columns 40 to stably support the truss support beam 20, ensuring the stability of the entire air rib membrane body 10.

[0039] In addition, it should be noted that the support column 40 is cast in the large volume concrete 100 and does not need to be removed when the air rib membrane structure is lifted. Instead, another support column 40 is connected and fixed to the original support column 40 by bolts, so that the end of the support column 40 can continue to remain above the large volume concrete 100 and support the truss support beam 20.

[0040] Furthermore, the height of the support columns 40 is lower than the height of the lifting columns 31. By setting the height of the lifting columns 31 to be higher than the height of the support columns 40, the air-ribbed membrane structure can be lifted to the highest point of the support columns 40 when the air-ribbed membrane structure is lifted once, thereby quickly lifting the air-ribbed membrane structure to the corresponding height.

[0041] Furthermore, both the supporting columns 40 and the lifting columns 31 are provided with truss support seats 50 for fixing the truss support beams 20 .

[0042] The truss support seat 50 installed on the support column 40 is used to support the truss support beam 20 when the height is not raised, so as to keep the truss support beam 20 stable;

[0043] The truss support beam 20 installed on the support column 40 is used to support the truss support beam 20 after the height is raised, so that the truss support beam 20 after the height is raised remains stable.

[0044] It is understandable that the truss support beam 20 is at a certain height from the mass concrete 100 when it is not raised, so that the mass concrete 100 can be insulated by the air vent body 10. At this time, the truss support beam 20 is supported by the truss support seat 50 provided on the support column 40, so that the truss support beam 20 remains stable, thereby maintaining the stability of the air vent body 10. After the truss support beam 20 is raised by the winch 32, the truss support seat 50 installed on the lifting column 31 supports the truss support beam 20, so that the winch 32 does not need to be subjected to force after raising the truss support beam 20 to the corresponding height, thereby allowing the truss support beam 20 to remain stable at the raised height, avoiding the winch 32 being continuously subjected to force, resulting in energy waste, or the winch 32 failing due to long-term operation.

[0045] Furthermore, the truss support base 50 includes a vertical plate 51 rotatably mounted on the lifting column 31 or the support column 40, and a horizontal plate 52 fixed to the vertical plate 51. The vertical plate 51 can rotate toward the side closer to the truss support beam 20. Since the truss support beam 20 is located inside the lifting column 31 and the support column 40, that is, the vertical plate 51 can rotate toward the inside of the lifting column 31 or the support column 40, thereby driving the horizontal plate 52 to rotate to the bottom of the truss support beam 20 and support the truss support beam 20. Bolt holes 511 are formed in the vertical plate 51, so that the rotation angle of the vertical plate 51 can be locked through the bolt holes 511, so that the horizontal plate 52 can stably support the truss support beam 20.

[0046] When the air rib membrane structure is lifted to the set height, the vertical plate 51 is driven to rotate, causing the horizontal plate 52 to rotate to the bottom of the truss support beam 20 and abut against the bottom side of the truss support beam 20 to support the truss support beam 20. At this time, the rotation angle of the vertical plate 51 is locked by bolts, so that the horizontal plate 52 can stably support the truss support beam 20.

[0047] Furthermore, in order to enable the cross plate 52 to stably support the truss support beam 20, fixing parts for fixing the truss support beam 20 are provided on the cross plate 52. There are two groups of fixing parts. The two groups of fixing parts cooperate to fix the truss support beam 20 to achieve the connection and fixation between the truss support beam 20 and the cross plate 52.

[0048] Specifically, the fixing part includes a U-shaped clamping sleeve 53 which is detachably mounted on the horizontal plate 52. The U-shaped clamping sleeve 53 is located on the top surface of the horizontal plate 52. The opening of the U-shaped clamping sleeve 53 faces the horizontal plate 52. A through hole 521 is provided on the horizontal plate 52 for the two ends of the U-shaped clamping sleeve 53 to pass through, and nuts 54 are threadedly provided on both ends of the U-shaped clamping sleeve 53 extending out from the bottom of the horizontal plate 52.

[0049] When the cross plate 52 rotates to the bottom of the truss support beam 20 and supports the truss support beam 20, the U-shaped sleeve 53 is clamped on a cross beam of the truss support beam 20 and the two ends of the U-shaped sleeve 53 are passed through the screw holes on the cross plate 52, and then the nut 54 is tightened to achieve a fixed connection between the truss support beam 20 and the cross plate 52. At this time, the connection between the cross plate 52 and the truss support beam 20 is stable and reliable, ensuring the stability of the truss support beam 20 and the air rib membrane body 10.

[0050] In this embodiment, in order to prevent the U-shaped ferrule from damaging the truss support beam 20 , an elastic pad 55 for contacting the surface of the truss support beam 20 is provided in the opening of the U-shaped ferrule.

[0051] In addition, it should be noted that the air plenum structure provided in this embodiment also includes a panel and a curtain 70. The panel is arranged around the outside of the lifting column 31, and the curtain 70 is arranged between the panel and the air plenum body 10. After the air plenum body 10 is raised to a certain height, the curtain 70 seals the gap between the air plenum body 10 and the panel, thereby forming an integrally sealed air plenum structure, thereby achieving thermal insulation for the large volume of concrete 100. At the same time, when the air plenum body 10 is raised, there is no need to remove the panel. Instead, the curtain 70 only needs to be separated from the panel, and then the air plenum body 10 is lifted using a lifting device. After the lifting is completed, the curtain 70 is connected to the panel to seal the gap between the air plenum body 10 and the panel.

[0052] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
