Description

Technology Field

[0001] The present invention relates to a composite test device for the actual verification of a waterproofing method, and more specifically, to a composite test device for the actual verification of a waterproofing method capable of evaluating mechanical behavior and airtightness performance by controlling temperature conditions while applying a combination of horizontal and vertical behavior and pressure environments to a test specimen coated or attached with a waterproofing material. Background Technology

[0003] Waterproofing materials applied to buildings, particularly underground, rooftop, and exterior wall structures, are repeatedly exposed to water pressure, temperature changes, structural micro-deformations, vibrations, and cracking behaviors over long periods. Consequently, relying solely on waterproofing performance in static conditions makes it difficult to adequately evaluate durability and long-term reliability in actual construction environments. Furthermore, since waterproofing layers can exhibit various damage patterns—such as delamination, peeling, rupture, and leakage—under conditions where they interact complexly with structural cracks, separation, torsion, vibration, and water pressure variations, testing technology is required to evaluate the performance of waterproofing materials by reproducing complex loads and environmental conditions similar to actual construction scenarios.

[0004] Accordingly, the previously disclosed registered patent No. 10-1105167 discloses a waterproofing pressure test device by torsion that tests waterproofing performance by simultaneously applying water pressure and torsion to a waterproofing layer, comprising a chamber having an internal receiving space and a cracked section, a movable part that generates torsion in the chamber, and a controller part that controls the same, in order to evaluate the performance of a waterproofing layer of a building structure in an environment similar to an actual structure. In particular, this prior art has technical significance in that it attempts to evaluate the behavioral characteristics of a waterproofing layer that are difficult to verify with conventional simple water pressure tests by simulating the water pressure and torsion conditions received by the waterproofing layer in combined wall sections and general sections.

[0005] However, the aforementioned conventional technology is fundamentally focused on test structures centered on hydrostatic pressure and torsional action, and thus has limitations in that it fails to sufficiently implement a structure that combines and imparts the horizontal and vertical behaviors experienced by waterproofing materials during actual construction. Furthermore, there is a lack of specific consideration regarding configurations that reproduce the interconnected behavior of horizontal and vertical sections by setting the test specimen to an L-shaped or corner-shaped base condition similar to actual construction conditions. Additionally, the complex environment evaluation system is inadequate for performing behavior and pressure tests either in conjunction or independently while controlling the temperature of the test environment over a wide range. Moreover, since technical configurations for quantitatively analyzing displacement or pressure changes occurring during testing through multi-point sensing, or for determining leakage based on pressure maintenance changes after immersion, are insufficient, there are structural limitations in reproducing complex deterioration environments similar to actual field conditions and precisely evaluating long-term reliability.

[0006] In addition, another prior art, Registered Patent No. 10-0986670, discloses a waterproofing performance testing device in which a lower chamber and an upper chamber are combined on a plate, a waterproofing sheet is interposed between them, and fluid is supplied through a supply port to test waterproofing performance. This prior art presents a technical configuration intended to more precisely evaluate the performance of a waterproofing layer in actual composite wall sections, including a plurality of penetrations penetrating the lower and upper specimens, a discharge port, a supply port, a fluid supply controller, a hydrostatic pressure gauge, a thermocouple, a temperature control chamber, and a circulation pump. It is characterized by the ability to determine the performance of the waterproofing sheet using the fluid discharge rate, hydrostatic pressure, and temperature. Furthermore, some embodiments propose a structure that applies vibration using a vibrator.

[0007] However, since the aforementioned conventional technology centers on a structure that checks for leakage by interposing a waterproof sheet between upper and lower chambers and supplying fluid, it has limitations in simulating the complex behavior that occurs under actual corner construction conditions where the horizontal and vertical sections of the test specimen are connected. In particular, because it lacks a structure that independently or synchronously imparts horizontal segmented behavior and vertical behavior to the base body to which the waterproofing material is attached, it is difficult to sufficiently reproduce situations where cracks and behaviors occur in a complex manner in actual structures. Furthermore, regarding the fixing structure of the waterproofing layer, technologies for stabilizing test specimen mounting, such as a rapid and repeatable mounting structure using magnetic materials and magnet clamps or an auxiliary fixing structure using fixing nuts, have not been considered. Additionally, technologies for quantitatively measuring surface deformation at multiple locations to analyze deformation distribution, or for recording video data during testing to track damage patterns, have not been specifically presented. As a result, while this conventional technology is effective for evaluating fluid leakage or waterproofing performance itself, it suffers from technical instability and limitations in application when it comes to comprehensively evaluating deterioration environments, structural behavior, pressure changes, and leakage detection under actual construction conditions within a single integrated test system.

[0008] As such, conventional waterproofing material testing technologies are structured around individual test conditions, such as hydrostatic pressure and torsion tests, or fluid supply and leakage measurement tests. Consequently, they share a common limitation in that it is difficult to consistently perform, on a single device, the combined horizontal and vertical behavior experienced by waterproofing materials in actual construction environments, temperature changes, pressurization and depressurization, leakage detection in immersed water, mounting stability of test specimens, quantitative measurement of deformation, and video recording of damage status. This leads to discrepancies between actual construction conditions and test conditions, reduced reproducibility and reliability of test results, and insufficient accuracy in long-term durability evaluation. Therefore, there is an urgent need to develop technology capable of simultaneously addressing combined horizontal and vertical behavior, temperature control, pressure testing, and leakage detection under conditions similar to actual construction environments.

A magnet clamp (50) disposed on the horizontal movement plate (31) and the vertical movement plate (41) of the horizontal movement part (30) and the vertical movement part (40), and magnetically coupled with the plate-shaped magnetic body (12) to fix the waterproofing material (A); a pressure test chamber (60) installed to be movable up and down to receive the waterproofing material (A) in a sealed state and perform a pressure test by pressurizing or depressurizing; and a pressure control unit (70) that controls the pressure and vacuum level of the sealed space (61) formed by the pressure test chamber (60). The invention includes a sensor unit (80) for detecting displacement and damage of the waterproofing material (A); wherein the horizontal movement unit (30) and the vertical movement unit (40) are each driven independently or in combination with each other to provide a combination of horizontal and vertical movement to the waterproofing material (A); and the pressure test chamber (60) is configured to operate in conjunction with or independently of one or more of the horizontal movement and vertical movement.

[0015] Additionally, the CRC board (11) is formed to include a horizontal section and a vertical section arranged at right angles to each other, wherein a horizontal area of ​​a waterproofing material (A) corresponding to a horizontal movement plate (31) is arranged in the horizontal section, and a vertical area of ​​a waterproofing material (A) corresponding to a vertical movement plate (41) is arranged in the vertical section.

[0016] In addition, the bed portion (10) including the plate-shaped magnetic body (12) is formed by dividing it into multiple parts to correspond to each horizontal movement plate (31) of the horizontal movement portion (30), and each plate-shaped magnetic body (12) is individually coupled with a corresponding magnet clamp (50) so that the displacement of each horizontal movement plate (31) is independently transmitted to the waterproofing material (A).

[0017] Additionally, the pressure test chamber (60) is lowered from the top of the waterproofing material (A) and comes into close contact with the surface of the waterproofing material (A) to form a sealed space (61), and selectively performs pressurization and depressurization within the sealed space (61), and the pressure control unit (70) is configured to control pressure, vacuum level, and holding time by including an air compressor and a vacuum pump.

[0018] In addition, the sensor unit (80) includes a distance sensor for measuring displacement of the surface of the waterproofing material (A) and a pressure sensor for measuring pressure of the sealed space (61), and the distance sensor is configured to determine the deformation distribution of the waterproofing material (A) by simultaneously measuring displacement at different locations of the waterproofing material (A).

[0019] Additionally, the horizontal movement part (30) and the vertical movement part (40) are supported by a slider rail (13) and are configured to be drawn out from inside the constant temperature chamber (20) to the outside or inserted into the constant temperature chamber (20) along the slider rail (13).

[0020] In addition, a screw hole (90) is formed in at least one of the horizontal movement plate (31) and the vertical movement plate (41), and the bed portion (10) is configured to be selectively fixed or released by a fixing nut fastened to the screw hole (90).

[0021] In addition, the sensor unit (80) further includes a camera for capturing the surface condition of the waterproofing material (A), and the camera is configured to record as image data whether the waterproofing material (A) is lifted, peeled, deformed, sagging, or leaking during or after the test.

[0022] Additionally, the pressure test chamber (60) is characterized by including a water supply valve (62) to allow water to be injected into the interior, and by being configured to fill the sealed space (61) with water to check for leakage of the waterproofing material (A).

[0023] Additionally, the pressure test chamber (60) is configured to be pressurized to a set water pressure by the pressure control unit (70) while water is injected into the sealed space (61), the sensor unit (80) measures the pressure change of the sealed space (61) over time, and the control unit is configured to compare the amount of pressure reduction or pressure maintenance rate over a certain period of time with a reference value, and to determine that a leak has occurred in the waterproofing material (A) if a pressure drop exceeding the reference value occurs.

[0024] In addition, the horizontal movement unit (30), vertical movement unit (40), pressure control unit (70), and sensor unit (80) are controlled in conjunction by the control unit, and the control unit collects the displacement value of the waterproofing material (A) and the pressure value of the sealed space (61) measured by the sensor unit (80) in real time, calculates an error value by comparing it with a preset target displacement value and target pressure value, generates a corrected control value by a learning algorithm based on the error value, adjusts the displacement amount, movement speed, and driving timing of the horizontal movement plate (31) and the vertical movement plate (41), and simultaneously synchronously controls the pressure of the sealed space (61) through the pressure control unit (70) to correspond to one or more of the displacement amount, movement speed, and driving timing of the horizontal movement plate (31) and the vertical movement plate (41).

[0025] In addition, the CRC board (11) is characterized by being formed from a composition comprising 25 to 50 parts by weight of cement, 3 to 15 parts by weight of cellulose fiber, 5 to 25 parts by weight of silica or silica sand, 3 to 20 parts by weight of fly ash, 3 to 20 parts by weight of metakaolin, 2 to 15 parts by weight of polymer binder, 10 to 35 parts by weight of shell powder, and 0.1 to 5 parts by weight of dispersant and fluidizing agent, so as to maintain lightweight and structural strength while mimicking the substrate conditions where the waterproofing material (A) is applied.

[0026] Additionally, a plurality of fastening holes (12a) are formed in the plate-shaped magnetic body (12), and the fastening holes (12a) are formed in a conical shape with a diameter that gradually expands from the top to the bottom. When the plate-shaped magnetic body (12) is placed on the bottom surface of a mold (M) and a composition for forming a CRC board (11) is injected into the mold (M) to form the board, a portion of the composition flows into the fastening holes (12a) to form a conical fastening projection (11a) corresponding to the shape of the fastening holes (12a). The conical fastening projection (11a) is provided to be mechanically engaged and coupled with the plate-shaped magnetic body (12) so that it is restricted from detaching in the drawing direction by the downward expansion shape of the fastening holes (12a). Effects of the invention

[0028] According to the above configuration and operation, the composite test device for actual verification of a waterproofing method according to the present invention stably mounts a test specimen, which is a combination of a CRC board and a plate-like magnetic material, onto the bed portion, precisely maintains a set temperature through a constant temperature chamber, and simultaneously imparts complex displacement to the test specimen through a horizontal movement portion and a vertical movement portion, and selectively implements pressurization and depressurization conditions through a pressure test chamber and a pressure control portion, thereby having the effect of reproducing an actual deterioration environment in which temperature, pressure, and mechanical behavior act simultaneously under laboratory conditions.

[0029] In addition, as the horizontal and vertical movement sections are driven independently or in combination, a non-uniform stress state in which different deformations occur at different locations is realized in the test specimen. Consequently, crack propagation, deformation patterns, and stress distribution occurring in actual structures can be simulated more realistically, thereby improving the accuracy of the test results.

[0030] In addition, the magnetic coupling structure between the magnet clamp and the plate-like magnetic material allows for the rapid and stable fixation of the test specimen. Furthermore, easy detachment is maintained even during repetitive testing, thereby ensuring both test efficiency and reproducibility.

[0031] In addition, pressurization and depressurization tests can be performed in a sealed space formed by a pressure test chamber, and leakage tests in a fresh water state can be performed through a water supply valve. Since the presence of leakage can be quantitatively determined based on the pressure retention rate or the amount of pressure reduction, the objectivity and reliability are improved compared to the evaluation method that relied on visual inspection as in the past.

[0032] In addition, by measuring the displacement of the test specimen at different locations and changes in pressure within the sealed space in real time through the sensor unit, and recording the surface condition as video data through the camera, it is possible to simultaneously analyze deformation, lifting, peeling, and leakage phenomena occurring during the test process both quantitatively and qualitatively.

[0033] In addition, by applying a learning algorithm based on sensor data to the control unit to synchronously control horizontal and vertical behavior and pressure conditions, errors regarding target test conditions can be minimized and complex load conditions can be precisely reproduced, thereby improving the repeatability and reliability of the test.

[0034] Furthermore, since the CRC board is formed from a composition containing waste shell powder, it is possible to simultaneously secure lightweightness and structural strength. In addition, the surface microstructure enhances interfacial bonding with waterproofing materials, providing a test environment similar to actual construction conditions, and the recycling of waste shells offers advantageous effects in terms of environmental aspects.

[0035] In addition, the mechanical interlocking structure between the conical fastening hole formed in the plate-shaped magnetic material and the corresponding fastening projection formed in the CRC board prevents detachment in the pulling direction and distributes the load, thereby maintaining bonding stability even under conditions of repetitive movement and pressure load, which has the effect of improving the structural reliability of the test specimen.

[0036] Thus, the present invention provides the effect of precisely reproducing complex degradation environments, quantitatively evaluating the long-term performance of waterproofing materials, and simultaneously improving the reproducibility and reliability of test results.

Furthermore, in describing the present invention, detailed descriptions of related known functions are omitted if they are deemed obvious to those skilled in the art and could unnecessarily obscure the essence of the invention.

[0041] The present invention relates to a composite test device for actual verification of a waterproofing method, wherein the present invention enables precise evaluation of the mechanical behavior and airtightness performance of a waterproofing material by performing a combination of horizontal and vertical behavior, temperature control, and pressure tests while a test specimen combining a CRC board and a magnetic body is fixed with a magnet clamp, comprising: a bed part (10) on which a waterproofing material (A) is applied or attached, comprising a CRC board (11) and a plate-shaped magnetic body (12) coupled to the rear surface of the CRC board (11); a constant temperature chamber (20) formed to accommodate the waterproofing material (A) together with the bed part (10) and configured to maintain the temperature of the constant temperature chamber (21) within a set range; a horizontal behavior part (30) disposed inside the constant temperature chamber (20) and comprising a plurality of horizontal behavior plates (31) formed by dividing them to implement the horizontal direction behavior of the waterproofing material (A) and each capable of being driven independently; and a vertical direction behavior of the waterproofing material (A) disposed inside the constant temperature chamber (20). It includes a vertical movement unit (40) comprising a vertical movement plate (41) driven to implement, a horizontal movement unit (30), a magnet clamp (50) disposed on the horizontal movement plate (31) and the vertical movement plate (41) of the vertical movement unit (40) and magnetically coupled with a plate-shaped magnetic body (12) to fix a waterproofing material (A), a pressure test chamber (60) installed to be movable up and down to receive the waterproofing material (A) in a sealed state and perform a pressure test by pressurizing or depressurizing, a pressure control unit (70) that controls the pressure and vacuum level of the sealed space (61) formed by the pressure test chamber (60), and a sensor unit (80) that detects displacement and damage of the waterproofing material (A).

[0042] Meanwhile, it further includes a control unit configured to integrally control the horizontal movement unit (30), the vertical movement unit (40), and the pressure control unit (70) based on data measured from the sensor unit (80).

[0043] The bed portion (10) according to the present invention is a structure that supports a waterproof material (A) in which a CRC board (11) and a plate-shaped magnetic body (12) are integrally combined as shown in FIG. 2, and is configured so that the load transmitted from the horizontal movement plate (31) and the vertical movement plate (41) is distributed to the front of the CRC board (11) through the plate-shaped magnetic body (12).

[0044] The above CRC board (11) is formed to include a horizontal section and a vertical section arranged perpendicularly to each other, and a horizontal area of ​​the waterproofing material (A) corresponding to the horizontal movement plate (31) is arranged in the horizontal section, and a vertical area of ​​the waterproofing material (A) corresponding to the vertical movement plate (41) is arranged in the vertical section. And due to this structure, a state in which horizontal and vertical deformation are combined is formed at the corner section of the waterproofing material (A).

[0045] The bed portion (10) including the above plate-shaped magnetic body (12) is divided into multiple parts to correspond to each horizontal movement plate (31) of the horizontal movement portion (30), and each plate-shaped magnetic body (12) is individually coupled with a corresponding magnet clamp (50) so that the displacement of each plate is independently transmitted to the waterproofing material (A).

[0046] At this time, the load transmitted from the horizontal movement plate (31) and the vertical movement plate (41) is decomposed into in-plane shear and out-of-plane bending components and transmitted throughout the CRC board (11), and since a uniform deformation state is formed without stress being concentrated at a specific point, a stress state similar to the actual structural crack behavior is realized.

[0047] In addition, the constant temperature chamber (20) according to the present invention forms a constant temperature chamber (21) inside to accommodate a bed portion (10), a horizontal movement portion (30), and a vertical movement portion (40), and reproduces thermal expansion and contraction conditions within a set temperature range. Accordingly, the waterproofing material (A) is evaluated in a state where mechanical behavior and thermal deformation are combined.

[0048] The above constant temperature chamber (20) may be configured to include a heating means and a cooling means disposed on the inner wall of the chamber to maintain the internal temperature of the constant temperature chamber (21) within a set range, a temperature sensor that detects the internal temperature of the constant temperature chamber (21), and a temperature control unit that controls the operation of the heating means and the cooling means based on a temperature signal input from the temperature sensor.

[0049] And the heating means may include a heater or a hot air generator, and the cooling means may include a cooling coil or a refrigerant circulation device, and if necessary, a circulation fan may be further provided to forcibly circulate the internal air in order to maintain a uniform temperature inside the constant temperature room (21).

[0050] With this configuration, a closed-loop control is performed in which the heating and cooling means are continuously corrected based on the deviation between the temperature value detected in real time by the temperature sensor and the set temperature value inside the constant temperature room (21), and the temperature gradient inside the constant temperature room (21) is mitigated by the forced circulation of air by the circulation fan, thereby suppressing the occurrence of localized overheating or undercooling regions.

[0051] In addition, the inner wall of the constant temperature chamber (20) is formed with an insulating structure so that heat exchange with the external environment is minimized, thereby improving the stability of maintaining the set temperature, and the temperature rise and fall response is maintained consistently even during repeated heating and cooling processes, ensuring the reproducibility of temperature control. Accordingly, the waterproofing material (A) maintains uniform thermal conditions while suppressing temperature fluctuations over time, and the combined deterioration conditions of mechanical behavior and thermal deformation are precisely reproduced, thereby improving the reliability and comparability of the test results.

[0052] In addition, the horizontal movement unit (30) according to the present invention has a plurality of horizontal movement plates (31) arranged in a divided manner so that each plate is driven independently, and the displacement, speed, and driving cycle of each plate are individually controlled.

[0053] Accordingly, the waterproofing material (A) is placed in a non-uniform stress state with different deformations depending on the location, and the crack propagation and deformation patterns of the actual structure are reproduced.

[0054] Additionally, the horizontal movement unit (30) is installed so that each horizontal movement plate (31) can move in a straight line back and forth by an individual drive unit, and the individual drive unit may be configured to include a servo motor or actuator and a drive transmission means that converts rotational motion into linear motion.

[0055] The above horizontal movement plate (31) is supported to move while maintaining alignment along the guide rail, and the movement displacement, speed, and driving cycle of each plate are independently set and driven by the control unit.

[0056] Accordingly, each horizontal movement plate (31) can be selectively moved in the same direction or in a different direction, or driven in mutually different phases, and accordingly, different deformation conditions are applied to the waterproofing material (A) at different locations, thereby enabling various crack occurrence and deformation patterns.

[0057] Furthermore, the horizontal movement unit (30) is configured such that a plurality of horizontal movement plates (31) are each controlled by individual driving units with different displacements, speeds, and cycles, or synchronized to enable simultaneous movement or divided movement. Accordingly, different deformations are induced in the waterproofing material (A) at different locations, thereby reproducing conditions for local stress concentration and crack expansion.

[0058] In addition, the vertical movement part (40) according to the present invention imparts vertical displacement to the waterproofing material (A) through the vertical movement plate (41), and when combined with the horizontal movement part (30), the waterproofing material (A) forms a composite movement state having two or more degrees of freedom. As a result, a state in which in-plane deformation and out-of-plane deformation act simultaneously is realized.

[0059] The vertical movement unit (40) is installed so that the vertical movement plate (41) can move linearly in the up and down direction by an individual drive unit, and the drive unit may be configured to include a servo motor or an actuator and a drive transmission means that converts rotational motion into linear motion. The vertical movement plate (41) is supported to move up and down while maintaining an alignment state so that tilting during movement is suppressed by a guide structure, and the movement displacement, speed, and drive cycle are set and controlled by the control unit.

[0060] Accordingly, the vertical movement plate (41) can perform repetitive lifting and lowering movements according to set displacement conditions, or be controlled in conjunction with the driving of the horizontal movement part (30) to have a phase difference, and accordingly, a movement condition similar to that of an actual structure in which vertical deformation and horizontal deformation of the waterproofing material (A) act in combination can be realized.

[0061] In FIGS. 3 and 4, the horizontal movement part (30) and the vertical movement part (40) are supported by a slider rail (13) and are drawn out from inside to outside or inserted into the constant temperature chamber (20) along the slider rail (13).

[0062] In addition, with this configuration, the horizontal movement part (30) and the vertical movement part (40) can move smoothly between the inside and outside of the constant temperature chamber (20) along the slider rail (13), so that the installation, replacement, and inspection of the waterproofing material (A) can be performed outside the constant temperature chamber (20), thereby improving accessibility for the worker and greatly improving work efficiency.

[0063] In addition, since test preparation and dismantling are possible without directly accessing the internal space of the constant temperature chamber (20), rapid changes in the internal temperature environment can be minimized, thereby maintaining the stability of the test conditions. Furthermore, since the movement path is consistently guided by the slider rail (13), repeated insertion and withdrawal are performed while maintaining the alignment of the horizontal movement part (30) and the vertical movement part (40), ensuring the positional alignment of the waterproofing material (A), and the same conditions can be reproduced during repeated tests, thereby improving the reproducibility and reliability of the test results.

[0064] In addition, the magnet clamp (50) according to the present invention magnetically combines with the plate-shaped magnetic body (12) to securely fix the waterproofing material (A) to the horizontal movement plate (31) and the vertical movement plate (41), and allows for repeated attachment and detachment while maintaining the continuity of the load transfer path.

[0065] The above magnet clamp (50) uniformly adheres the waterproofing material (A) to the horizontal movement plate (31) and the vertical movement plate (41) by means of magnetic adsorption force with the plate-shaped magnetic body (12), thereby preventing slipping or detachment of the waterproofing material (A) even under repeated loads and vibrations occurring during movement, and securing a stable load transfer path in which the load is directly transferred to the waterproofing material (A) without intermediate loss.

[0066] In this way, damage to the waterproofing material (A) or localized stress concentration is prevented by the magnetic fastening method of the above-mentioned magnet clamp (50), and the mounting and dismounting of the test specimen are performed quickly, thereby improving work efficiency during repeated testing. Furthermore, since the same fixing conditions can be repeatedly reproduced, consistency of test conditions is ensured, and the reliability and reproducibility of test results are improved.

[0067] In addition, a screw hole (90) is formed in at least one of the horizontal movement plate (31) and the vertical movement plate (41), and the bed portion (10) is selectively fixed or released by a fixing nut fastened to the screw hole (90).

[0068] The fastening structure using the above screw hole (90) and fixing nut can mechanically assist in restraining the bed portion (10) in addition to magnetic fixation by the magnet clamp (50), so that minute gaps or positional changes that may occur under high load or repetitive motion conditions are suppressed and the positional stability of the waterproofing material (A) is further improved.

[0069] In particular, since the bed portion (10) is firmly supported against the inertial force and reaction force generated in a composite motion state where the horizontal motion portion (30) and the vertical motion portion (40) are driven simultaneously, consistency in load transfer is maintained and displacement transfer error according to test conditions is minimized.

[0070] In addition, by releasing the fixing nut as needed, the bed portion (10) can be easily detached, making replacement and setting work of the waterproofing material (A) easier, and the fixing strength can be selectively adjusted according to test conditions, so there is an effect of being able to flexibly respond to various test environments.

[0071] Additionally, the pressure test chamber (60) according to the present invention descends from the top of the waterproofing material (A) to form a sealed space (61), and pressurization or depressurization is performed by a pressure control unit (70). The pressure control unit (70) includes an air compressor and a vacuum pump, and controls the pressure, vacuum level, and holding time of the sealed space (61) to apply a repetitive pressure load to the waterproofing material (A).

[0072] Additionally, the pressure test chamber (60) may be formed in a box shape with an open bottom so as to form a sealed space (61) by adhering to the surface of the waterproofing material (A) when descending from the top of the waterproofing material (A), and a sealing member may be provided at the bottom of the chamber to improve adhesion so as to block the inflow of external air.

[0073] Additionally, the pressure test chamber (60) may be formed with at least a portion of a transparent plate so that the internal condition can be checked from the outside, and accordingly, the deformation state of the waterproofing material (A), whether leakage has occurred, and the behavior of the internal fluid can be checked visually or via video during the test.

[0074] The pressure control unit (70) includes an air compressor, a vacuum pump, a pressure regulating valve, and a flow control means to increase or decrease the pressure of the sealed space (61) to a set value and to maintain it stably for a set maintenance time.

[0075] In this way, the pressure test chamber (60) can secure airtightness of the sealed space (61) by stably maintaining a state of contact with the waterproofing material (A), and the pressure control unit (70) can repeatedly reproduce wind pressure or water pressure conditions acting on the actual structure by precisely controlling the speed of pressure rise and fall.

[0076] In addition, as the pressure in the sealed space (61) is controlled to be maintained constant, minute leakage or deterioration of the airtightness performance of the waterproofing material (A) can be quantitatively detected, and since internal observation is possible through a transparent plate, the presence or absence of abnormalities in the test process can be intuitively checked. Furthermore, since the repetitive pressurization and depressurization cycles are stably performed, the reproducibility of the test conditions is ensured, and the durability and airtightness performance of the waterproofing material (A) under various pressure conditions can be reliably evaluated.

[0077] And, the pressure test chamber (60) descends from the top of the waterproofing material (A) to form a sealed space (61), selectively performs pressurization and depressurization within the sealed space (61), and the pressure control unit (70) controls the set pressure, vacuum level, and holding time.

[0078] In addition, the sensor unit (80) according to the present invention includes a distance sensor for measuring the displacement of the waterproofing material (A) and a pressure sensor for measuring the pressure of the sealed space (61), and measures the displacement and pressure change of the waterproofing material (A) at each location in real time.

[0079] In this way, the horizontal movement section (30) and the vertical movement section (40) are each driven independently or in combination with each other simultaneously, and the pressure test chamber (60) operates in conjunction with or independently of one or more of the horizontal movement and vertical movement to form a composite deterioration environment in which structural movement and pressure load are combined.

[0080] In particular, the horizontal movement part (30) and the vertical movement part (40) can be controlled synchronously or asynchronously on the same time axis to implement complex movement of various phase combinations.

[0081] The sensor unit (80) includes a distance sensor and a pressure sensor, and determines the deformation distribution by simultaneously measuring displacement at different locations of the waterproofing material (A).

[0082] In addition, the distance sensors included in the sensor unit (80) are positioned at multiple locations spaced apart from each other so as to face the surface of the waterproofing material (A), and each distance sensor may be configured to continuously measure the amount of displacement of the waterproofing material (A) relative to a reference position in a non-contact manner.

[0083] At this time, the distance sensor may include a laser displacement sensor, an optical displacement sensor, or an ultrasonic sensor, and the signal output from each sensor is transmitted to a control unit and collected as displacement data by position. Accordingly, the displacement of the area corresponding to the central part and the edge part, or the horizontal part and the vertical part of the waterproofing material (A) is measured simultaneously, and the local deformation and overall deformation pattern of the waterproofing material (A) are analyzed based on the difference in displacement between each position.

[0084] As an example, FIG. 5 (a) shows a state in which the degree of deformation of a sample is measured using a Time of Flight (ToF) sensor, and FIG. 5 (b) shows a state in which the degree of damage to a sample is measured using a pressure sensor.

[0085] In addition, the pressure sensor is positioned to measure the pressure inside the sealed space (61) in real time, and time history data regarding pressure changes is transmitted to the control unit. The control unit is configured to quantitatively determine the deformation response of the waterproofing material (A) occurring under specific pressure conditions by analyzing the multi-point displacement data collected from the distance sensor and the pressure data collected from the pressure sensor in conjunction. In particular, if displacement increases rapidly or an abnormal deformation pattern occurs in a specific area of ​​the waterproofing material (A), it is possible to determine whether there is local damage by comparing this with displacement data from other locations, and to more precisely determine the possibility of reduced airtightness performance or leakage by analyzing the correlation with pressure changes.

[0086] Accordingly, the deformation of the waterproofing material (A) is measured simultaneously at multiple points rather than at a single point and interpreted as a spatial deformation distribution, so the structural behavior can be evaluated more accurately compared to simple maximum displacement measurement, and the reliability of the test results and the precision of the analysis are improved by tracking the deformation response in real time in a state combined with pressure load.

[0087] In addition, the sensor unit (80) further includes a camera to record the surface condition of the waterproof material (A) as image data.

[0088] The above camera can continuously capture the surface condition of the waterproofing material (A) during and after the test and record it as image data, so the timing of occurrence and progression of damage patterns such as lifting, peeling, cracking, deformation, and leakage can be tracked in a time history.

[0089] Accordingly, qualitative evaluations that relied on visual observation can be supplemented to enable objective record-based analysis, and by linking the displacement and pressure data and image data obtained through the sensor unit (80), the correlation between the cause of damage and behavioral characteristics can be identified more precisely. In addition, by comparing and analyzing image data obtained under the same test conditions, reproducibility between repeated tests can be verified, and the reliability of test results and data usability are improved.

[0090] Additionally, the pressure test chamber (60) includes a water supply valve (62) and injects water into the sealed space (61) to evaluate whether there is leakage in a fresh water state.

[0091] The pressure test chamber (60) is pressurized to a set water pressure while water is injected, and the sensor unit (80) continuously measures the pressure change of the sealed space (61) over time, and the control unit calculates the pressure maintenance rate or pressure reduction rate based on the pressure value after a set time has elapsed compared to the reference pressure value set at the start of the test, and if the pressure reduction rate exceeds a pre-set allowable reference value, it is determined that leakage has occurred in the waterproofing material (A).

[0092] The above leak determination is performed by a control unit, and the control unit is configured to output a determination result by comparing the measured pressure change data with a preset reference value.

[0093] At this time, the above allowable standard value is defined as the range of the allowable pressure reduction rate relative to the standard pressure set according to the test conditions, and the above preset time is set by the control unit according to the test conditions.

[0094] Accordingly, the pressure test chamber (60) can stably apply a set water pressure while the sealed space (61) is filled with water, so it can precisely reproduce the water pressure conditions acting on the actual structure and sensitively detect even minute leakage of the waterproofing material (A) as a pressure change.

[0095] In particular, since the pressure retention rate or pressure reduction amount is quantitatively calculated based on the time history data of the pressure measured through the sensor unit (80), the presence or absence of leakage is objectively determined according to numerical standards, enabling a precise airtightness evaluation that does not rely on visual observation. In addition, since the pass / fail judgment of the test results is made based on consistent standards through comparison with a pre-set allowable standard value, the reproducibility and reliability of the test results are improved, and by adjusting the standard value according to various test conditions, the performance of the waterproofing material (A) can be systematically evaluated by condition.

[0096] Additionally, the horizontal movement unit (30), vertical movement unit (40), pressure control unit (70), and sensor unit (80) are controlled in conjunction by a control unit (e.g., an electronic control system including a computing device and memory). The control unit calculates an error value by comparing position-specific displacement data and pressure data collected in real-time from the sensor unit (80) based on target displacement value, target speed value, and target pressure value set prior to the test, and generates a corrected control value through a learning algorithm that uses the error value as an input value. The control unit adjusts the displacement amount, movement speed, and driving timing of the horizontal movement plate (31) and the vertical movement plate (41) according to the generated control value, and simultaneously synchronously controls the pressure of the sealed space (61) through the pressure control unit (70) to correspond to one or more of the displacement amount, movement speed, and driving timing of the horizontal movement plate (31) and the vertical movement plate (41).

[0097] Additionally, the control unit may be configured to include a computing device and a memory, wherein the memory stores reference data corresponding to each test condition along with target displacement values, target speed values, and target pressure values ​​set before the test, and the computing device may be configured to receive position-specific displacement data and pressure data input in real time from the sensor unit (80) and continuously calculate an error value corresponding to the difference from the target value.

[0098] The above learning algorithm is configured to learn the correlation between error values ​​and control inputs based on displacement response and pressure response data accumulated during previous testing processes, and can be configured to output a corresponding correction control value when a current error value is input.

[0099] And, the control unit precisely adjusts the displacement amount, movement speed, and driving timing of the horizontal movement plate (31) and the vertical movement plate (41) while correcting errors caused by time delay, non-linear response, or disturbance in real time, and at the same time, synchronously controls the pressure of the sealed space (61) through the pressure control unit (70) so that it has the same phase as the movement condition or a set phase difference.

[0100] In this way, the mechanical behavior and pressure load applied to the waterproofing material (A) act in a state of precise temporal alignment, so that the complex load conditions occurring in the actual structure can be reproduced more accurately.

[0101] In addition, by combining sensor feedback-based closed-loop control with correction by a learning algorithm, control errors and deviations caused by environmental changes that may occur during repeated tests are continuously corrected, thereby improving the reproducibility of test conditions and increasing the reliability of the deformation response and airtightness performance evaluation results of the waterproofing material (A). Furthermore, since control performance is gradually improved based on data accumulated under various test conditions, it has the effect of enabling stable and consistent testing even for waterproofing materials (A) that exhibit complex non-linear behavior.

[0102] In addition, the CRC board (11) is formed from a composition comprising 25 to 50 parts by weight of cement, 3 to 15 parts by weight of cellulose fiber, 5 to 25 parts by weight of silica or silica sand, 3 to 20 parts by weight of fly ash, 3 to 20 parts by weight of metakaolin, 2 to 15 parts by weight of polymer binder, 10 to 35 parts by weight of shell powder, and 0.1 to 5 parts by weight of dispersant and fluidizing agent, so as to maintain lightweight and structural strength while mimicking the substrate conditions where the waterproofing material (A) is applied.

[0103] The limitation of each compositional component of the above CRC board (11) to the above weight range goes beyond simple material selection and corresponds to a critical range for satisfying mutual balance conditions to simultaneously secure lightness, strength maintenance, durability, and uniform deformation behavior.

[0104] First, if the cement content is less than 25 parts by weight, the absolute amount of binder is insufficient, so the compressive strength and flexural strength of the hardened body are significantly reduced, and there is a risk that the CRC board (11) itself will be damaged by repeated movement loads. Conversely, if the content exceeds 50 parts by weight, the relative proportion of shell powder and lightweight components decreases, which reduces the lightweighting effect of the board and increases drying shrinkage, which increases the likelihood of cracking.

[0105] In addition, if the cellulose fiber content is less than 3 parts by weight, the reinforcing effect of suppressing crack propagation when a crack occurs is not sufficiently exerted, and if it exceeds 15 parts by weight, poor aggregation and dispersion between fibers may occur, which may instead form a localized weakened area.

[0106] If the amount of silica or silica sand is less than 5 parts by weight, it lacks the role of an aggregate and structural stability is reduced, and if it exceeds 25 parts by weight, the fluidity of the mixture is reduced, moldability is poor, and it becomes difficult to form a uniform structure.

[0107] If fly ash and metakaolin are each less than 3 parts by weight, the microstructure densification effect due to the pozzolanic reaction is not sufficiently observed, and if each exceeds 20 parts by weight, the development of initial strength is delayed or the possibility of shrinkage and cracking increases due to excessive fine particles.

[0108] If the polymer binder is less than 2 parts by weight, the interfacial adhesion and water resistance with the inorganic binder are not sufficiently secured, and the adhesion stability with the waterproofing material (A) is reduced, and if it exceeds 15 parts by weight, the overall rigidity is reduced and excessive deformation may occur due to the excessive organic component.

[0109] In particular, the shell powder is dispersed within the bonding structure formed by the cement hydration product and acts as a filler constituting the internal microstructure of the CRC board (11), and depending on its content, the continuity of the bonding structure and load transfer characteristics appear differently. When the content of the shell powder is less than 10 parts by weight, it exists as a simple filler within the continuous bonding structure formed by the cement hydration product, and the effects of forming a micro-pore structure and increasing surface roughness appear limitedly, and accordingly, the lightweighting effect of the CRC board (11) and the improvement effect of interfacial bonding with the waterproofing material (A) are not sufficiently expressed.

[0110] On the other hand, if the content of the shell powder exceeds 35 parts by weight, the continuous bonding network formed by the cement hydration product is weakened or partially severed, causing the inter-particle bonding structure to change discontinuously, and consequently, the density of the internal structure decreases and transitions into a structure where microcracks easily occur. In this case, the CRC board (11) exhibits characteristics such as unstable load transfer paths when an external force is applied, and reduced compressive strength and flexural strength.

[0111] Therefore, the content range of the aforementioned shell powder functions as a critical range corresponding to the boundary where the maintenance state and the collapse state of the bonding structure are distinguished, as it is a section where a continuous bonding structure based on cement hydrate is stably maintained while a micropore structure and surface roughness are effectively formed.

[0112] In addition, if the amount of dispersant and fluidizer is less than 0.1 parts by weight, it is difficult to uniformly disperse the multi-component composition, which may result in molding defects, and if it exceeds 5 parts by weight, material separation and bleeding may occur due to excessive fluidity.

[0113] As such, the weight ranges of each component interact in conjunction, and if any of them fall outside the above range, a problem arises in which at least one of the performance characteristics—lightness, strength, durability, and uniform deformation behavior—is degraded; therefore, the above numerical ranges constitute a critical limitation for simultaneously satisfying the performance of the test substrate required by the present invention.

[0114] Meanwhile, by including waste shell powder within the above composition range, an additional environmental effect is secured that allows for the recycling of waste shells generated as industrial and fishery by-products, going beyond the function of a simple lightweight filler. Specifically, since waste shells are waste that previously caused an environmental burden during landfill or disposal processes, utilizing them as a component of the CRC board (11) can reduce the amount of waste generated and promote the circular use of resources. In particular, since recycling is carried out within a range where the waste shell powder forms a composite structure with a cementitious binder while maintaining structural performance, its value as a functional material is secured beyond the level of simple waste treatment.

[0115] The application of such waste materials has additional technical significance in terms of responding to environmental regulations and developing eco-friendly building materials, in addition to mechanical performance such as lightweighting and strength maintenance. Consequently, the CRC board (11) according to the present invention can simultaneously provide excellent effects in terms of structural performance, construction condition simulation performance, and resource recycling.

[0116] In addition, the shell powder is a fine particle composed mainly of calcium carbonate (CaCO₃) that forms a fine irregular structure and pores on the surface of the CRC board (11) and, together with the cement hydration product, densely forms a fine structure, thereby increasing the surface roughness and effective contact area. Accordingly, when the waterproofing material (A) is applied or attached, a mechanical locking effect is induced, and a portion of the waterproofing material (A) penetrates into the fine pores, thereby strengthening the physical bond.

[0117] As a result, peel resistance is improved at the interface between the CRC board (11) and the waterproofing material (A), and interfacial separation and lifting are suppressed even under repeated deterioration environments and behavioral load conditions, thereby improving the stability of long-term waterproofing performance.

[0118] In FIG. 6, a plurality of fastening holes (12a) are formed in the plate-shaped magnetic body (12), and the fastening holes (12a) are formed in a conical shape with a diameter that expands from the top to the bottom. When the CRC board (11) is formed, a composition is introduced into the fastening holes (12a) to form a conical fastening projection (11a), and the fastening projection (11a) is formed such that it is restricted from detaching in the pulling direction by the expanded shape of the fastening holes (12a), thereby configuring a mechanical locking connection between the plate-shaped magnetic body (12) and the CRC board (11).

[0119] Accordingly, the above CRC board (11) and plate-shaped magnetic body (12) maintain a structurally bonded state that does not separate under pulling load without a separate adhesive means, and interfacial separation is suppressed even under repetitive motion loads and deterioration environments, thereby stably securing the structural integrity of the waterproofing material (A).

[0120] In addition, due to this configuration, the fastening hole (12a) and the fastening projection (11a) form a mechanical locking structure rather than a simple adhesive bond, so the bonding force between the CRC board (11) and the plate-shaped magnetic body (12) is significantly improved against the load in the pulling direction. In particular, since the fastening hole (12a) has a conical shape with a diameter that expands toward the bottom, the fastening projection (11a) formed in correspondence with it is prevented from coming loose due to the locking effect during pulling, and even if repetitive motion loads or vibrations are applied, the detachment or gap of the joint is prevented.

[0121] As such, when forming the above CRC board (11), the composition is directly introduced into the fastening hole (12a) and hardened as a single unit, thereby ensuring structural integrity without requiring a separate fastening member or adhesive process, and preventing problems such as interfacial peeling or a decrease in bonding strength due to adhesive deterioration. Accordingly, the repetitive load transmitted from the horizontal movement part (30) and the vertical movement part (40) is stably transmitted to the CRC board (11) through the plate-shaped magnetic body (12), and the bonded state is maintained even during long-term testing.

[0122] Furthermore, since multiple fastening holes (12a) are distributed, the load is not concentrated at a specific location but is distributed and transmitted through multiple fastening protrusions (11a), thereby alleviating local stress concentration and reducing the risk of cracking or damage to the CRC board (11). As a result, the structural stability of the waterproofing material (A) is improved, and consistent behavioral characteristics can be maintained even under repeated test conditions, which has the effect of improving the reliability and reproducibility of the test results.

[0123] As described above, according to an embodiment of the present invention, a complex environment combining structural behavior, temperature change, and pressure conditions can be implemented in a single device, thereby enabling the precise reproduction of actual usage conditions of the waterproofing material.

[0124] As described above, the detailed description of the present invention has explained the most preferred embodiment of the present invention, but various modifications are possible within the scope of the technical scope of the present invention. Accordingly, the scope of protection of the present invention should not be limited to the above embodiment, but should be recognized to include the technologies of the claims described below and equivalent technical means derived from these technologies.
