Description

Apparatus and method for managing membrane structures {APPARATUS AND METHOD OF MEMBRANE STRUCTURE}

The present invention relates to a management technology of a membrane structure, and more particularly, it detects in real time that a state of a membrane structure is deformed or a characteristic deteriorates over time after the membrane structure is installed, so that an immediate action can be taken.

A membrane structure is a structure using coated fabrics as the main material, and is widely used due to the diversity of architectural expressiveness and beautiful formative beauty. In addition, due to the light transmittance of the membrane material used, the interior space is bright, light weight, and workability, etc. It is widely used as a major structural method for large-scale stadiums, outdoor performance halls, outdoor stages, shade curtains, market passage arcades, and various sports facilities. .

However, due to the limitations of the maintenance technology and disaster prevention technology of the membrane structure, a large number of large membrane structures that are damaged by heavy snow and typhoons are being restored and reconstructed.

Membrane structures (ductile structures) have large displacement behavior in nature, so when a resonant load by wind loads acts, large displacement occurs, and the structure is vulnerable to collapse even by a small wind. In addition, when the creep phenomenon occurs in the membrane structure, the initial tension is lost, thereby increasing the displacement caused by the external load. . In addition, when an unexpected snow load acts on the flexible structure when designing the structure, a ponding phenomenon occurs and additional snow acts on the deformed structure to collapse due to the snow load. A controllable device is required. For example, when an unexpected strong external force (typhoon, tornado, etc.) acts on the membrane structure during structure design, the membrane may flutter and collapse due to the resonance effect. A control device for damping may be proposed.

As a prior art to respond to this, there is a device that generates vibration using sound waves, detects and analyzes the generated vibration, and measures the membrane tension, but there is a disadvantage that dynamic control of the membrane material cannot be performed. As another prior art, there is a device for measuring the membrane tension through a resonance phenomenon caused by sound waves, but there is a problem in that dynamic control is impossible and constant monitoring cannot be performed.

Referring to FIG. 1 , the membrane structure 100 according to the present invention includes a roof membrane 110 , a steel beam 110A, a membrane structure frame 120 and a support 130 .

The roof membrane 110 is a membrane material that has waterproof properties and partially or completely blocks light.

The steel beam 110A serves to support the roof membrane 110 from the lower side to maintain a desired shape. At this time, a plurality of steel beams (110A) are provided in parallel along one direction. The steel beam 110A may be formed in various shapes such as a straight line or an arc shape.

Membrane structure frame 120 is installed on both sides of the steel beam (110A) serves to connect and fix both edges of the steel beam (110A). The membrane structure frame 120 is made of a material having sufficient rigidity, and can be deformed into various shapes. In addition, the membrane structure frame 120 serves to pull both edges of the roof membrane 110 to maintain the expanded state.

The support 130 serves to support the membrane structure frame 120 . The support 130 can be deformed into various shapes, and the steel beam 110A and the support 130 are made of a material having sufficient rigidity.

Therefore, in the state in which the membrane structure 100 is initially installed, the roof membrane 110A maintains an unfolded state without wrinkling or sagging as a whole.

The roof membrane 110A may sag, discolor, and wear or leak due to natural phenomena such as wind, rain, snow, and sunlight over time.

However, the roof membrane 110A can continue to maintain its original unfolded state regardless of the lapse of time by the apparatus 200 for managing the membrane structure as shown in FIG. 2 , which will be described in detail as follows.

Referring to FIG. 2 , the apparatus 200 for managing a membrane structure according to the present invention includes a sensor unit 210 , a control unit 220 , a display unit 230 , a communication unit 240 , a wireless communication terminal 250 , and a wired communication terminal. (260).

The sensor unit 210 detects that the roof membrane 110A is stretched, discolored and worn or leaked due to natural phenomena such as wind, rainwater, snow and sunlight over time, and outputs a detection signal accordingly. And, it serves to correct the slack of the roof membrane (110A) itself.

To this end, the sensor unit 210 includes a tension detection module 210A, a color detection sensor 210B, a wear detection sensor 210C, and a water leak detection sensor 210D.

The tension sensing module 210A may detect the sagging (or sagging) of the roof membrane 110A, output a sensing signal corresponding thereto, and serve to correct the slack to its original state. A plurality of tension sensing modules 210A were installed on two opposite sides of the four edge sides of the roof membrane 110A in order to sense the sagging of the entire roof membrane 110A.

In the present embodiment, an arbitrary side among the four edge sides of the roof membrane 110A will be referred to as a first side X1, and the remaining three sides will be referred to as second to fourth sides X2-X4 in a counterclockwise direction. At this time, a plurality of tension sensing modules 210A were installed on the first side X1 and the fourth side X4, which are two sides facing each other. A plurality of tension sensing modules 210A may be installed on the first side X1 and the fourth side X4, respectively. In this embodiment, each of the six tension sensing modules 210A is installed at equal intervals.

Tension sensing modules 210A installed on each of the first side X1 and the fourth side X4 each have the same structure and perform the same role, so one of them will be described with reference to FIG. 3 as follows. . For reference, FIG. 3 shows the first tension sensing module installed on the left among the six tension sensing modules 210A installed on the first side X1 of the roof membrane 110A. Referring to FIG. 3 , the tension sensing module 210A according to the present invention includes a tension bolt 141 , a pressure sensor 142 , a hydraulic jack 143 , an anti-loosening nut 144 and a fixing nut 145 .

The tension bolt 141 is connected to the roof membrane 110 via the U-shaped strip 111 . The tension bolt 141 is inserted and installed in the support plate 112 to move freely.

The pressure sensor 142 converts and outputs a pressure change due to tension with the roof membrane 110 into an electrical signal. The type of the pressure sensor 142 may be implemented in various ways, for example, a load cell may be used.

The hydraulic jack 143 increases the tension corresponding to the sagging or sagging of the corresponding portion of the roof membrane 110 due to creep, snow load, wind load, etc. occurring in the roof membrane 110, thereby maintaining the original tension. .

The anti-loosening nut 144 serves to prevent loosening of the fixing nut 145 . For this purpose, the anti-loosening nut 144 is preferably installed at the front end of the fixing nut 145 .

According to the tightening position of the fixing nut 145 , the repulsive force of the compression spring installed inside the tension sensing module 210A is adjusted to adjust the tension of the roof membrane 110 . At this time, when a stable tension is applied to the roof membrane 110, the fixing nut 145 is adjusted so that a constant buffer gap is maintained between the pair of spring caps installed inside the tension sensing module 210A.

The control unit 220 analyzes the degree of elongation of the corresponding portion of the roof membrane 110 based on the pressure change signal output from the pressure sensor 142 and displays the analyzed elongation information on the display unit 230 as well as the communication unit ( 240) is printed.

In this case, there may be various methods for the control unit 220 to display the sagging information on the display unit 230 . The sagging information may include time information at which sagging of the roof membrane is sensed, a location where sagging occurs, and a degree of sagging. Here, the degree of sagging can be displayed by dividing it into several preset steps (eg, 10 steps), and a message indicating that tension adjustment is required can also be displayed. 4A shows an example of display of such sagging information. Here, the time at which the sagging was sensed was 2021.03.31., the degree of sagging was 20%, and it was shown that the location where the sagging occurred was the X12 sector. Here, 100% of the sagging percentage means a preset limit of sagging.

In contrast, the communication unit 240 transmits the information on the sagging of the roof membrane 110 to the wired communication terminal 260 through a wire, and on the other hand, transmits it to the wireless communication terminal 250 through a wireless communication network. .

Accordingly, the membrane structure manager can recognize the sagging information of the roof membrane 110 in real time through the display unit 230 when in the field, and when outside, a wired communication terminal 260 such as a desktop or notebook computer ) through which information on the sagging of the roof membrane 110 can be recognized in real time, and can be recognized in real time through a wireless communication terminal 250 such as a smartphone or tablet PC.

At this time, the controller 220 controls the driving of the hydraulic jack (not shown in the drawing) based on the sagging information of the roof membrane 110 , thereby increasing the tension of the hydraulic jack 143 , and thus the corresponding portion of the roof membrane 110 . is maintained in its original tension.

In this way, the controller 220 controls the hydraulic jack 143 based on the sagging information of the roofing membrane 110 supplied through the above path, so that the tension of the roofing membrane 110 without the administrator taking a separate action. can always be maintained in its original tension.

As another embodiment, the membrane structure manager directly based on the sagging information of the roof membrane 110 displayed through the display unit 23 or the wireless communication terminal 250 or the wired communication terminal 260. By increasing the tension of the corresponding region, the tension of the roof membrane 110 can always be maintained at the original tension.

The color sensor 210B may be installed on one or more places of the roof film 110 . The color detection sensor 210B detects the color of the corresponding portion of the roof film 110 and outputs a color detection signal accordingly.

5A is a detailed block diagram showing an embodiment of the color detection sensor 210B.

Referring to FIG. 5A , a “high” or “low” signal is output to the terminals S2 and S3 of the main chip 212 through the microcontroller 211 to obtain red (R), green (G) and When green color (B) is selected, the main chip 212 selects the maximum frequency through the terminals S0 and S1 according to the maximum frequency processing speed of the microcontroller 211, and the microcontroller 211 selects the main chip ( 212), it is possible to determine the color based on the frequency output through the output terminal (OUT). The control unit 220 repeats the above process three times through the color sensor 210B to read each value of R, G, and B, and then combines these values to obtain the color for the corresponding point of the roof membrane 110 . can be detected.

FIG. 5B is a table for selection options of the main chip 212 , and FIG. 5C shows color coordinates detected by the controller 220 through the color sensor 210B.

At this time, the control unit 220 displays the color change of the roof film 110 detected by the color sensor 210B on the display unit 230 . In this case, there may be various methods for the control unit 220 to display the color change on the display unit 230 . For example, the degree of color change can be divided into several preset steps (eg, 10 steps) and displayed, and when the degree of color change is severe, a message indicating that repair or replacement of the roof membrane 110 is required may be At the same time, the control unit 220 outputs the color change information (discoloration information) as described above to the communication unit 240 .

4B shows an example of displaying such color change information. Here, the time at which the color change was sensed was March 31, 2021, the degree of the color change was in three stages, and the location where the color change occurred was sector X12 and X42.

In contrast, the communication unit 240 transmits the color change information of the roof membrane 110 to the wired communication terminal 260 through a wire, and on the other hand, transmits it to the wireless communication terminal 250 through a wireless communication network. do.

Accordingly, the manager can immediately take necessary measures for the color change of the roof membrane 110 .

The wear sensor 210C may be installed on one or more places of the roof membrane 110 . The wear sensor 210C detects the degree of wear of the corresponding part of the roof membrane 110 and outputs a wear detection signal accordingly.

At this time, the control unit 220 displays the wear change information of the roof membrane 110 detected by the wear sensor 210C on the display unit 230 . In this case, there may be various methods for the control unit 220 to display the wear change information on the display unit 230 . For example, the degree of wear change can be displayed by dividing it into several preset steps (eg, 10 steps), and if the degree of wear is severe, a message indicating that repair or replacement of the roof membrane 110 is required there is. At the same time, the control unit 220 outputs the wear change information as described above to the communication unit 240 .
