Description

TECHNICAL FIELD

[0001] The present application relates to the field of architectural structure design, in particular to a kind of anti-collapse inflatable membrane structure. BACKGROUND

[0002] Membrane structure is a kind of light space structure, with rich and colorful modeling, architectural characteristics, superior structure characteristics, mainly divided into tensioned membrane structure, skeleton membrane structure and inflatable membrane structure etc. Inflatable membrane structure is one of important branches, unlike traditional space structure building, this kind of structure is a relatively closed space structure, through fan to structure inside air blowing, so that the pressure difference between inside and outside membrane structure is maintained, to ensure the rigidity and stability of membrane structure system, maintain the shape of design.

[0003] Compared with traditional building, the biggest advantage of inflatable membrane structure is its light and portable characteristics. Inflatable membrane structure can be installed quickly in a very short time, and can also be quickly disassembled and moved. Another advantage is its environmental protection and low carbon characteristics. The construction and demolition of traditional building will produce a large amount of waste and carbon dioxide emissions, which will pollute the environment to a certain extent, while inflatable membrane structure can be used repeatedly, and the membrane material is maintenance-free during the service life; At the same time, the membrane material has a certain light transmittance, which can reduce or even eliminate artificial lighting during the day, thereby reducing energy consumption.

[0004] But with the application of inflatable membrane structure, its limitations are increasingly prominent, and there have been many cases of inflatable membrane structure collapse. The structure needs to install electric control inflation system and equipment, and if the membrane leaves the holding of the fan, collapse phenomenon is easy to appear. Natural disasters such as strong wind, heavy rain, etc. are also important factors leading to the collapse of inflatable membrane structure. Strong wind can tear the membrane material; Heavy rain may cause local water accumulation of membrane material and collapse. With global climate change, extreme weather is frequent, and the demand for anti-collapse inflatable membrane structure is increasingly urgent. SUMMARY

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of the present application more clear and explicit, the present application is further described in detail below in combination with examples and figures, the schematic embodiments of the present application and the description thereof are only used to explain the present application, and do not limit the present application.

[0053] Example 1: The present example 1 provides a collapse-preventing inflatable membrane structure, as shown in Figure 1 and Figure 2 , which comprises:

[0054] A mold body 3 is provided with an additional cable net 2;

[0055] A stiff reinforcing cable 1 is arranged on the main force path of the mold body 3.

[0056] The stiff reinforcing cable 1 is a telescopic rod, which is in a stretched state when the mold body 3 is inflated.

[0057] In the prior art, natural disasters such as strong wind and heavy rain are also important factors leading to the collapse of the inflatable membrane structure. Strong wind can tear the membrane material, and heavy rain can cause local water accumulation of the membrane material to be too large to collapse. The present application provides an anti-collapse inflatable membrane structure, which can effectively prevent the continuous collapse of the inflatable membrane structure and ensure the safety of the structure. In the specific scheme, a mold body 3 and an additional cable net 2 provided on the mold body 3 are included. The membrane surface additional cable net 2 makes the membrane structure bulge in a long strip shape 301 or a hole shape 301 under the action of internal pressure, thereby reducing the radius of curvature of the membrane surface and reducing the stress value of the membrane surface. However, the traditional cable net can only bear tension. Once the downward load makes the cable loose, the cable net will stop working. Therefore, the present application further provides a stiff reinforcing cable 1, which is not uniformly distributed in the inflatable membrane structure. The density of the stiff reinforcing cable 1 can be adjusted according to the importance of the structure to achieve a reasonable and efficient design. The traditional cable is replaced by the stiff reinforcing cable 1 on the main force path, which is attached to the membrane surface and forms a common force system with the surrounding tension cable system to form an inflatable membrane cable net structure that can bear tension and pressure. In specific operation, the mold body 3 is first inflated to make the structure reach a predetermined height. At this time, the stiff reinforcing cable 1 is in an elongated state. When the structure has excessive deformation and has a risk of collapse, the stiff reinforcing cable 1 will be compressed with the retraction of the mold body 3. When the stiff reinforcing cable 1 reaches the maximum compression amount, it cannot be compressed again to bear pressure and support the entire mold body 3 to reach a balanced state and avoid collapse. After the natural disaster disappears or the leakage point is repaired, the mold body 3 can return to the original state during continuous inflation. Therefore, the anti-collapse inflatable membrane structure described above can improve the vertical bearing capacity of the inflatable membrane structure without the need to set up columns or change the layout of the building space. It can ensure the anti-collapse performance of the inflatable membrane structure in the case of power failure, strong wind, heavy snow, heavy rain and other extreme conditions. It expands the application range and realizes an energy-saving and environment-friendly low-carbon building with high safety reserve.

[0058] Regarding the main force path: the membrane structure generally adopts a shell surface shape or a cylindrical surface shape, as shown in Figure 1 In the shell surface shaped membrane structure, the main force path is in the radial direction of the membrane structure. Figure 2As shown, in the cylindrical membrane structure, the main force path is along the circumferential direction of the membrane structure. The main force path is obtained by identifying and optimizing the structural failure mode. The incremental analysis method is used to record the response of the structure from the elastic to the elastic-plastic until the structure collapses and destroys. The idea of ductility design is used to avoid damage concentrated in a certain part, and the stiffening cable is arranged on the failure path to realize the pre-control of the failure mode of the structure, which is of great significance to improve the anti-collapse ability of the structure.

The telescopic section includes a first end head 101 and a second end head 102 which are internally hollow and oppositely arranged. A limiting block 103 is arranged between the first end head 101 and the second end head 102, and the two ends of the limiting block 103 respectively extend into the first end head 101 and the second end head 102.

[0061] The two ends of the limiting block 103 are provided with limiting rods 104 which are arranged along the radial direction of the stiffening cable 1. The two sides of the end of the first end head 101 and the second end head 102 which face each other are provided with long strip sliding holes 105 which are arranged along the axial direction of the stiffening cable 1.

[0062] The two ends of the limiting rod 104 pass through the two long strip sliding holes 105 which face each other and can slide along the length direction of the long strip sliding hole 105. In this scheme, this telescopic structure can be preferably adopted. In this telescopic structure, the displacement telescopic amount is provided by the sliding displacement of the limiting rod 104. The stiffening cable 1 is an elastic rod which can accept bending deformation. When the mold body 3 is inflated and the structure reaches the preset height, the stiffening cable 1 is stretched to the limit state, as shown in Figure 5 That is, the first end head 101 and the second end head 102 are farthest apart. When the membrane structure produces excessive deformation and has a risk of collapse, the stiffening cable 1 will be compressed with the retraction of the mold body 3 until the limiting rod 104 cannot move, or the first end head 101 abuts against the second end head 102, at which time it cannot be retracted again, as shown in Figure 6 Thus, the pressure bearing is opened to support the entire mold body 3 to reach a balanced state again and avoid collapse.

In the scheme, the hanger 5 is arranged at the top center of the position of the bulge 301, and the two ends of the telescopic hose 4 are respectively connected to the two low sides of the bulge 301, so that under the suspension of the hanger 5, the telescopic hose 4 can be closer to the film surface at the position of the bulge 301, at this time, a plurality of gas pressure sensors 6 are arranged inside the telescopic hose 4, and the probes of the gas pressure sensors 6 are extended, so that a gas pressure detection area can be arranged at each position of the bulge 301, and the serial number is marked through the control end; when leakage occurs at a certain position of the bulge 301, the internal gas pressure of the bulge 301 at this position will quickly decrease, so according to the average value and the maximum value of the gas pressure decrease detection results in any area, the detection area with the maximum gas pressure decrease and the detection area with the maximum average value of the gas pressure decrease are selected, and at most two bulge 301 areas are obtained, at this time, the leakage point can be quickly found through manual detection.

[0083] In order to quickly find the leakage point or the tearing point, the air pressure detection area is arranged at the position of each bulge 301 through the air pressure sensor 6 on the telescopic hose 4, and the serial number is marked through the control end; when the leakage occurs at a certain bulge 301, the internal air pressure of the bulge 301 will quickly decrease at this time, so according to the average value and the maximum value of the air pressure decrease detection result, the detection area with the maximum air pressure decrease and the detection area with the maximum average value of the air pressure decrease are selected, so that the most two bulge 301 areas are obtained, and the leakage point can be quickly found through manual detection at this time.

[0084] In the leakage process, in order to avoid the phenomenon that the bulge 301 surface is collapsed, thereby affecting the appearance of the whole membrane structure, a temporary support assembly is further arranged, the temporary installation mode is that the adhesive layers on both sides of the bearing plate 15 are respectively adhered to the low points on both sides of the bulge 301, a sleeve 7 is further arranged in the middle of the bearing plate 15, the sleeve 7 partially extends into the bulge 301, and a fan 8 is arranged at the outer end of the sleeve 7; when the leakage occurs, the temporary support assembly is installed at the leakage position, the fan 8 is started, and the sealing door plate 10 is opened, at this time, the fan 8 transports air into the air bag 9, the air bag 9 rapidly expands and extends out of the sleeve 7, until abutting and being pressed on the lower side of the bearing plate, thereby supporting the bulge 301 above, avoiding the excessive deformation of the bulge 301 position, and after the support is in place, the fan 8 and the electromagnetic valve are closed.

[0085] Finally, after repairing the leakage point, the temporary support assembly can be removed, then the air bag 9 is reset, the gas in the air bag 9 is released first, then the air bag 9 is inserted into the sleeve 7 again, finally the sealing door plate 10 is placed on the ring plate 11, and the electromagnetic iron is started to reset the air bag 9, so as to facilitate the repeated use of the temporary support assembly.
