Technical Field

[0001] The present invention relates to the technical field of wall opening sealing testing, in particular to a wall opening sealing testing method and a wall opening sealing testing device. Background Art

[0002] Wall openings are fitted with closures such as doors, windows, or curtain walls. Wall openings should be well sealed, meaning there should be a good seal between the wall opening and the closure. Poor sealing of wall openings can reduce the building's thermal insulation performance.

[0003] Currently, the existing method for testing the sealing of wall openings is as follows: covering the wall opening with plastic sheeting and adhering the plastic sheeting to the wall surface with double-sided tape to form a closed space between the plastic sheeting and the sealing member; passing an air pipe through the plastic sheeting and extending it into the closed space, and then sealing the plastic sheeting and the air pipe with tape; then connecting an air pressure detection device to the air pipe so that the air pressure detection device is connected to the closed space; and then testing the sealing of the closed space using the air pressure detection device.

[0004] In the aforementioned testing method, a simple wall opening sealing test device consists of plastic sheeting, air pipes, tape, double-sided tape, and an air pressure tester. However, due to the poor adhesion of the double-sided tape, air leakage often occurs between the plastic sheeting and the wall surface, resulting in poor sealing test results. Summary of the Invention

[0005] A technical problem to be solved by the present invention is that the accuracy of existing wall opening sealing detection methods is relatively poor.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a wall opening sealing test method on one hand, which comprises: S1, arranging a sealing gasket that can be distributed around the wall opening on the side of the static pressure plate facing the wall surface; S2, laying the static pressure plate on the wall surface and making the sealing gasket surround the wall opening, and then pressing the static pressure plate to the wall surface by a clamping mechanism to form a closed space between the static pressure plate and the closing member; and S3, connecting an air pressure detection device to the static pressure plate, and connecting the air pressure detection device to the closed space, and then the air pressure detection device performs a pressure test on the sealing of the closed space.

[0007] In some embodiments, step S1 further includes: assembling multiple sub-panels into multiple horizontal rows of sub-panels arranged along the length direction of the sub-panels; assembling all the horizontal rows of sub-panels in sequence along the width direction of the sub-panels to form a static pressure plate; and / or, step S3 further includes: the air pressure detection device fills gas into the enclosed space to make the pressure of the enclosed space reach a preset pressure, and then the air pressure detection device detects the real-time pressure value of the enclosed space, and the detection personnel judge the sealing of the wall opening based on the change of the real-time pressure value within a preset time period.

[0008] In some embodiments, step S1 further includes: assembling two adjacent rows of sub-panels together horizontally through an intermediate gusset plate to form a static pressure panel.

[0009] In some embodiments, step S1 further includes: installing a fastener assembly around the periphery of the static pressure plate; step S2 further includes: pressing the fastener assembly against the wall surface through a pressing mechanism so that the static pressure plate is pressed against the wall surface.

[0010] In some embodiments, the fastener assembly includes two first gussets and multiple second gussets; step S1 further includes: installing a second gusset on both sides of the sub-panel in the length direction of the sub-panel in a horizontal row; installing a first gusset on both sides of the static pressure plate in the width direction of the sub-panel.

[0011] In some embodiments, step S1 further includes: providing a sealing gasket on a side of the fastener assembly facing the wall surface.

[0012] In some embodiments, the clamping mechanism includes multiple clamping components and multiple fixings for fixing the clamping components to the wall surface; step S2 further includes: assembling the multiple clamping components in sequence along the arrangement direction of the fastener components, and fixing the clamping components to the wall through the fixings.

[0013] In some embodiments, the clamping assembly includes a positioning member, a pressure plate and multiple spring members; both ends of the positioning member are respectively provided with through-holes for the fixing member to pass through, the middle part of the positioning member is recessed away from the fastener assembly to form an installation groove, all spring members are distributed in the installation groove at intervals, and the length of the spring member in the natural state is greater than the depth of the installation groove, the pressure plate is connected to the installation groove through the spring member and its length does not exceed the length of the installation groove, and the pressure plate is used to press the fastener assembly; for two adjacent clamping assemblies, the end of one positioning member can be plugged into the end of the other positioning member and the through-holes of the two positioning members are aligned; step S2 further includes: plugging the positioning members of all the clamping assemblies in sequence, and aligning the through-holes of the two adjacent positioning members, and then fixing the fixing member to the wall through the two through-holes to fix the clamping assembly to the wall.

[0014] In some embodiments, before step S1 , the method includes: providing a plurality of first installation holes on the wall that are distributed around the wall opening and are used to install fixing members.

[0015] On the other hand, the present invention also provides a wall opening sealing test device, which is used to implement the above-mentioned wall opening sealing test method. The wall opening sealing test device includes a static pressure plate, a clamping mechanism and an air pressure detection device. The clamping mechanism is used to press the static pressure plate against the wall surface. A ring-shaped sealing gasket is provided on one side of the static pressure plate, and an air hole is provided on the static pressure plate. The air pressure detection device is connected to the air hole.

[0016] The above technical solution of the present invention has the following beneficial effects: The clamping mechanism can press the static pressure plate against the wall surface, preventing it from falling off. The sealing gasket can seal between the static pressure plate and the wall surface, preventing air leakage between the static pressure plate and the wall surface. This allows the air pressure detection device to obtain more accurate results when testing enclosed spaces. Therefore, the wall opening sealing test method of the present invention has a high degree of accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0020] like Figure 1 、 Figure 2 、 Figure 8 and Figure 10 As shown, the present invention provides a wall opening sealing test device, which includes a static pressure panel assembly 1, a pressing mechanism 2, and an air pressure detection device 5. The static pressure panel assembly 1 has an inner side surface of the panel for contacting with a wall surface 31. The inner side surface of the panel is provided with a sealing gasket 4 distributed around the wall opening 32. The static pressure panel assembly 1 is provided with an air hole. The pressing mechanism 2 is configured to press the static pressure panel assembly 1 against the wall surface 31, so that a closed space connected to the air hole is formed between the static pressure panel assembly 1, the sealing member 33, and the sealing gasket 4. The air pressure detection device 5 is connected to the air hole to detect the sealing of the closed space.

[0021] Specifically, the static pressure panel assembly 1 is laid on the wall surface 31, and the sealing gasket 4 is sealed between the wall surface 31 and the static pressure panel assembly 1. The pressing mechanism 2 is installed on the wall surface 31 and the static pressure panel assembly 1 is pressed against the wall surface 31 to form a closed space between the static pressure panel assembly 1, the wall surface 31 and the sealing gasket 4. The air pressure detection device 5 is then connected to the air holes of the static pressure panel assembly 1 so that the air pressure detection device 5 is connected to the closed space. The air pressure detection device 5 then pressurizes the closed space so that the air pressure in the closed space reaches the rated pressure, and then the pressure in the closed space is monitored by the air pressure detection device 5. The air pressure detection device 5 can monitor the changes in the pressure of the closed space within a preset time period, and the inspection personnel can understand the sealing condition based on the pressure changes.

[0022] In the present invention, the pressing mechanism 2 can press the static pressure panel assembly 1 against the wall surface 31, preventing the static pressure panel assembly 1 from falling off the wall surface 31. The sealing gasket 4 can seal between the static pressure panel assembly 1 and the wall surface 31, preventing air leakage between the static pressure panel assembly 1 and the wall surface 31. The air pressure detection device 5 can obtain more accurate results after testing the enclosed space. Therefore, the wall opening sealing test device of the present invention has high detection accuracy.

[0023] like Figure 2 As shown, in some embodiments of the present invention, the static pressure panel assembly 1 includes a static pressure plate 13 and a fastener assembly 14 that surrounds and is removably sealed to the outer periphery of the static pressure plate 13. The sealing gasket 4 is connected to the side of the fastener assembly 14 facing the wall surface 31 and extends along the arrangement direction of the fastener assembly 14. The pressing mechanism 2 is configured to press the fastener assembly 14 against the wall surface 31 to form a closed space between the static pressure plate 13 and the sealing member 33.

[0024] Specifically, the static pressure plate 13 can be a rectangular plate, and the fastener assembly 14 can be a hollow rectangular frame. The static pressure plate 13 is sealedly mounted inside the fastener assembly 14, or in other words, the fastener assembly 14 surrounds the periphery of the static pressure plate 13 and is sealed therewith. The sealing gasket 4 is closely attached to the side of the fastener assembly 14 facing the wall surface 31. The sealing gasket 4 extends along the arrangement direction of the fastener assembly 14, so that the sealing gasket 4 is configured as a rectangular frame surrounding the wall opening 32. Of course, the fastener assembly 14 is detachably connected to the outer periphery of the static pressure plate 13 to facilitate disassembly and assembly.

[0025] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, the static pressure plate 13 is configured to be rectangular and includes a plurality of sub-panels 131 distributed in a matrix in the same plane. In the length direction of the static pressure plate 13, the two outermost rows of sub-panels 131 are sealedly connected to the fastener assembly 14 through a mortise and tenon structure, which is convenient for assembly and disassembly and helps to ensure sealing. In the width direction of the static pressure plate 13, the two outermost rows of sub-panels 131 are sealed and plugged into the fastener assembly 14. The connection method is simple, convenient for assembly and disassembly and helps to ensure sealing. Two adjacent sub-panels 131 are detachably sealed. Since the static pressure plate 13 is assembled from a plurality of sub-panels 131, a corresponding number of sub-panels 131 can be selected for assembly according to the size of the wall opening 32 to avoid the static pressure plate 13 being too large or too small, which helps to expand the application range of the wall opening sealing test device. The fastener assembly 14 can constrain all sub-panels 131 to make the static pressure panel assembly 1 stable and reliable.

[0026] like Figure 1 and Figure 2 As shown, an air pipe 12 is sealedly inserted through the air hole of the static pressure plate 13. The air pressure detection device 5 is removably and sealedly connected to the air pipe 12. The air pipe 12 is provided with two first flange plates spaced apart along its axial direction, and the static pressure plate 13 is clamped between the two first flange plates. The first flange plates can also be threadedly connected to the air pipe 12. One end of the air pipe 12 can communicate with the enclosed space, and one end of the air pipe 12 is removably connected to the air pressure detection device 5.

[0027] In addition, an air duct 11 for testing wind pressure resistance is also sealed and penetrated through the static pressure plate 13. When testing the sealing performance of the wall opening 32, the air duct 11 is in a completely closed state.

[0028] like Figure 3 As shown, in some embodiments of the present invention, in the length direction of the static pressure plate 13, two adjacent sub-panels 131 are sealed and connected by a mortise and tenon structure.

[0029] Specifically, the sub-panel 131 includes a panel body 1311 and two connecting blocks. These two connecting blocks are located on either side of the panel body 1311 in the longitudinal direction, and the thickness of the connecting blocks is greater than that of the panel body 1311. The side of the connecting block facing the panel body 1311 is provided with a mounting groove, and the two sides of the panel body 1311 are sealed and fixed in these two mounting grooves. One of the connecting blocks has a first T-shaped tenon 1312 on the side facing away from the panel body 1311, and the other connecting block has a first mortise 1313 on the side facing away from the panel body 1311. The first tenon 1312 and the first mortise 1313 extend along the width of the static pressure plate 13. In addition, the first mortise 1313 extends through the connecting block along the width of the static pressure plate 13, and the length of the first mortise 1313 and the length of the first tenon 1312 are equal to the width of the panel body 1311. For two adjacent panel bodies 1311, the first tenons 1312 of one panel body 1311 fit into the first mortises 1313 of the other panel body 1311, completing the assembly of the two. Of course, for the two edge rows of panel bodies 1311, there will be a row of first tenons 1312 and a row of first mortises 1313 that are not connected to the other panel bodies 1311. However, these rows of first tenons 1312 and first mortises 1313 are sealedly connected to the fastener assembly 14 in a mortise and tenon structure.

[0030] like Figures 1 to 4 As shown, in some embodiments of the present invention, along the width direction of the static pressure plate 13, every two adjacent rows of sub-panels 131 are detachably sealed and connected by an intermediate gusset plate 132. The intermediate gusset plate 132 can enhance the stability and reliability of the entire static pressure plate 13, prevent the sub-panels 131 in two adjacent rows from moving relative to each other, and prevent the middle portion of the static pressure plate 13 from deforming after inflation.

[0031] like Figure 4 As shown, in some embodiments of the present invention, the intermediate buckle plate 132 is provided with slots 1321 on both sides of the static pressure plate 13 in the width direction, and the two rows of sub-panels 131 adjacent to the intermediate buckle plate 132 are sealed and inserted into the two slots 1321 respectively to enhance the stability and reliability of the entire static pressure plate 13.

[0032] like Figure 4As shown, in some embodiments, the slot 1321 includes a first long slot 1322 and a plurality of first short slots 1323. The first long slot 1322 extends along the length of the intermediate gusset plate 132, while the first short slots 1323 extend along the width of the intermediate gusset plate 132. The lengths of the first long slots 1322 and the first short slots 1323 are perpendicular to each other, and all first short slots 1323 are spaced apart along the length of the intermediate gusset plate 132. The first long slot 1322 is used to insert into the panel body 1311, while the first short slots 1323 are used to insert into the connecting blocks on both sides of the panel body 1311. When a row of sub-panels 131 are inserted into the slot 1321 of the intermediate gusset plate 132, the panel body 1311 is positioned in the first long slot 1322, and the two connecting blocks, which are connected by mortise and tenon, are inserted into the first short slots 1323.

[0033] like Figure 2 As shown, in some embodiments of the present invention, the fastener assembly 14 includes two first gussets 141 and multiple second gussets 143. The two first gussets 141 are located on both sides of the static pressure plate 13 in the width direction, and the multiple second gussets 143 are located on both sides of the static pressure plate 13 in the length direction. The first gussets 141 are provided with a plug-in slot 142 on the side facing the static pressure plate 13. The static pressure plate 13 is sealedly inserted into the plug-in slot 142 of the two first gussets 141 on both sides of the static pressure plate 13 in the width direction. Each row of sub-panels 131 in the static pressure plate 13 is sealedly connected to the two second gussets 143 on both sides of the static pressure plate 13 in the width direction through a mortise and tenon structure.

[0034] Specifically, the first gusset plate 141, the second gusset plate 143, and the intermediate gusset plate 132 connect all sub-panels 131 into a sealed whole and maintain a seal between the static pressure plate 13 and the wall surface 31. Furthermore, the number of second gusset plates 143 can be four, six, or eight, etc., and the present invention is not limited thereto. Of course, a sealing gasket 4 is provided on both the side of the first gusset plate 141 facing the wall surface 31 and the side of the second gusset plate 143 facing the wall surface 31.

[0035] like Figure 5As shown, in some embodiments, the insertion slot 142 includes a second long slot 1421 and a plurality of second short slots 1422. The second long slot 1421 extends along the length of the intermediate gusset plate 132, while the second short slots 1422 extend along the width of the intermediate gusset plate 132. The lengths of the second long slots 1421 and the second short slots 1422 are perpendicular to each other, and all second short slots 1422 are spaced apart along the length of the intermediate gusset plate 132. The second long slots 1421 are used to insert into the panel body 1311, while the second short slots 1422 are used to insert into the connecting blocks on both sides of the panel body 1311. When a row of sub-panels 131 are inserted into the insertion slot 142 of the intermediate gusset plate 132, the panel body 1311 is positioned in the second long slots 1421, and the two connecting blocks connected to each other by mortise and tenon are inserted into the second short slots 1422.

[0036] like Figure 2 、 Figure 6 and Figure 7 As shown, in some embodiments, a portion of the second gusset plates 143 has a second tenon 1432 on the side facing the static pressure plate 13, while another portion of the second gusset plates 143 has a second mortise 1431 on the side facing the static pressure plate 13. The first mortise 1313 of a portion of the outermost sub-panels 131 are connected to the second tenons 1432 of a portion of the second gusset plates 143 in a mortise-and-tenon structure, while the first tenons 1312 of another portion of the outermost sub-panels 131 are connected to the second mortise 1431 of another portion of the second gusset plates 143 in a mortise-and-tenon structure. Furthermore, the ends of a portion of the second gusset plates 143 are in sealing contact with the first gusset plate 141 and the middle gusset plates 132, respectively, while the ends of another portion of the second gusset plates 143 are in sealing contact with the two middle gusset plates 132, respectively, to ensure the sealing of the static pressure panel assembly 1.

[0037] It should be noted that to ensure sealing, a layer of sealing material is provided at all locations involved in assembly of the static pressure panel assembly 1. For example, a layer of sealing material is provided at the first tenon 1312, the first mortise 1313, the slot 1321, the insertion slot 142, the second mortise 1431, and the second tenon 1432 to ensure sealing at the assembly locations.

[0038] In addition, before testing the sealing of the wall opening 32, in order to further ensure the sealing of the static pressure panel assembly 1 and further ensure the accuracy of the test, a sealant can be applied to the assembly part, or a tape can be attached to the assembly part, or a plastic film can be adhered to the assembly part. Figure 2 As shown, sealant can be applied to the joints between adjacent sub-panels 131 , sealant can be applied to the joints between the sub-panels 131 and the fastener assembly 14 , and sealant can be applied to the joints between the sub-panels 131 and the middle gusset plate 132 .

[0039] In some embodiments, the pressing mechanism 2 may include a plurality of slender pressure strips and a plurality of screws. The pressure strips are arranged in a "well" shape, and both ends of the pressure strips are fixed to the wall by screws.

[0040] like Figure 1 As shown, in some embodiments of the present invention, the clamping mechanism 2 includes a plurality of clamping assemblies 21 distributed in sequence along the arrangement direction of the fastener assembly 14 and a plurality of fixing parts 214 for fixing the clamping assemblies 21 to the wall 3, and two adjacent clamping assemblies 21 are connected in a plug-in manner.

[0041] Specifically, all compression assemblies 21 are sequentially inserted along the arrangement of the fastener assemblies 14 to form a frame-shaped compression mechanism 2. After the compression mechanism 2 is fixed to the wall 3, the sealing gasket 4, fastener assemblies 14, and compression mechanism 2 overlap in a direction perpendicular to the wall surface 31 to ensure a tight seal between the static pressure panel and the wall 3.

[0042] like Figure 9 As shown, in some embodiments of the present invention, the clamping assembly 21 includes a positioning member 211, a pressure plate 213 and a plurality of spring members 212. The middle portion of the positioning member 211 is recessed toward the fastener assembly 14 to form a mounting groove. All spring members 212 are distributed at intervals on the bottom wall of the mounting groove, and the length of the spring member 212 in a natural state is greater than the depth of the mounting groove. The pressure plate 213 is connected to the mounting groove through the spring member 212 and its length does not exceed the length of the mounting groove. The pressure plate 213 can press the fastener assembly 14.

[0043] Specifically, positioning member 211 is a rod member comprising a first rod segment, two second rod segments, and two third rod segments. One end of the two second rod segments is perpendicularly connected to the ends of the first rod segment to form a mounting slot, and the two third rod segments are connected to the other ends of the two second rod segments, respectively, and the third rod segments are parallel to the first rod segments. All spring members 212 are spaced apart along the length of the first rod segment, and the length of the spring members 212 is greater than that of the second rod segments. One end of the spring member 212 is threadedly mounted on the first rod segment, and the other end of the spring member 212 is threadedly mounted on the pressure plate 213. The length of the pressure plate 213 does not exceed the distance between the two second rod segments.

[0044] like Figure 9 As shown, in some embodiments of the present invention, one end of the positioning member 211 is provided with an insert 2114, and the other end of the positioning member 211 is provided with a positioning groove 2111 extending along the length of the positioning member 211 and a positioning hole 2112 extending along the width of the positioning member 211. For two adjacent pressing assemblies 21, the insert 2114 of one positioning member 211 is inserted into the positioning groove 2111 or the positioning hole 2112 of the other positioning member 211.

[0045] Specifically, the free end of one of the third rod segments is provided with an insert 2114, the free end of the other third rod segment is provided with a positioning groove 2111 that is recessed toward the second rod segment, and the free end of the other third rod segment is further provided with a positioning hole 2112 that extends along the width direction of the positioning member 211. The extending directions of the positioning hole 2112 and the positioning groove 2111 are parallel to the static pressure plate 13, and the extending directions of the positioning hole 2112 and the positioning groove 2111 are perpendicular to each other. For two clamping assemblies 21 located in the same straight line, the insert 2114 of one clamping assembly 21 is inserted into the positioning groove 2111 of the other clamping assembly 21. For two clamping assemblies 21 that are perpendicular to each other, the insert 2114 of one clamping assembly 21 is inserted into the positioning hole 2112 of the other clamping assembly 21.

[0046] like Figure 9 As shown, in some embodiments of the present invention, both ends of the positioning member 211 are respectively provided with through holes 2113 for the fixing member 214 to pass through.

[0047] Specifically, one through-hole 2113 extends through the insert block 2114, and the other through-hole 2113 extends through the free end of the other third rod. When the insert block of one clamping assembly 21 is inserted into the positioning groove 2111 or positioning hole 2112 of the other clamping assembly 21, the two through-holes 2113 face each other, and the fixing member 214 can be inserted into these two through-holes 2113.

[0048] In some embodiments of the present invention, the fixing member 214 is a screw, which is simple and reliable and helps to firmly connect the pressing assembly 21 to the wall 3. Of course, an expansion tube connected to the screw can also be preset in the wall 3 to prevent the screw from loosening.

[0049] like Figure 10 and Figure 11 As shown, the present invention also provides a wall opening sealing test method. The wall opening sealing test method includes: S1, disposing a sealing gasket 4 that can be distributed around the wall opening 32 on the side of the static pressure plate 213 facing the wall surface 31; S2, laying the static pressure plate 213 on the wall surface 31 so that the sealing gasket 4 surrounds the wall opening 32, and then pressing the static pressure plate 213 against the wall surface 31 by the pressing mechanism 2 to form a closed space between the static pressure plate 213 and the sealing member 33; and S3, connecting the air pressure detection device 5 to the static pressure plate 213, so that the air pressure detection device 5 is connected to the closed space, and then the air pressure detection device 5 performs a pressure test on the sealing of the closed space.

[0050] Specifically, the pressing mechanism 2 can press the static pressure plate 213 against the wall surface 31, preventing it from falling off. The sealing gasket 4 can seal between the static pressure plate 213 and the wall surface 31, preventing air leakage between the static pressure plate 213 and the wall surface 31. The air pressure detection device 5 can obtain more accurate results after testing the enclosed space. Therefore, the wall opening sealing test method of the present invention has a high degree of accuracy.

[0051] In some embodiments of the present invention, step S1 further includes: assembling multiple sub-panels 131 into multiple sub-panel rows arranged along the length direction of the sub-panel 131; assembling all sub-panel rows in sequence along the width direction of the sub-panel 131 to form a static pressure plate 13.

Step S2 further includes: pressing the fastener assembly 14 against the wall surface 31 by the pressing mechanism 2, so that the static pressure plate 13 is pressed against the wall surface 31.

[0056] Specifically, the pressing mechanism 2 can apply pressure to the fastener assembly 14 to prevent the static pressure plate 13 from being deformed and sunken toward the wall opening 32 due to direct pressure applied to the static pressure plate 13 .

Therefore, step S2 further includes: inserting the positioning pieces 211 of all the clamping components 21 in sequence, aligning the through holes 2113 of two adjacent positioning pieces 211, and then fixing the fixing piece 214 to the wall 3 through the two through holes 2113 to fix the clamping component 21 to the wall 3.

[0064] Specifically, by fixing the pressing components 21 one by one, it helps to ensure that the pressing components 21 firmly press the fastener components 14 onto the wall surface 31 .

[0065] In some embodiments of the present invention, before step S1 , the method includes: providing a plurality of first installation holes distributed around the wall opening 32 and used for installing the fixing members 214 in the wall 3 .

[0066] Specifically, pre-setting the first mounting holes helps to speed up the installation of various components and improve detection efficiency.

[0069] In some embodiments of the present invention, step S3 further includes: the air pressure detection device 5 fills the enclosed space with gas to make the pressure of the enclosed space reach a preset pressure, and then the air pressure detection device 5 detects the real-time pressure value of the enclosed space, and the detection personnel judge the sealing of the wall opening 32 based on the change of the real-time pressure value within a preset time period.

[0070] In some embodiments, the air pressure detection device 5 fills the enclosed space with gas so that the pressure in the enclosed space reaches a preset pressure A Pa. Then the detection personnel continuously detect the air pressure in the enclosed space for 2 minutes through the air pressure detection device 5. After 2 minutes, the real-time pressure in the enclosed space is B Pa. Then the difference between the air pressure values ​​A and B is compared with the industry standard value to determine whether the sealing of the wall opening 32 meets the standard.

[0071] The present invention also provides another wall opening sealing test device.
