The inner heat resistant plate 1 and the outer heat resistant plate 3 are non-combustible flat plates. Such as gypsum board, calcium silicate board, and the like. The thickness of the inner heat-resistant plate 1 and the outer heat-resistant plate 3 may be 5mm to 30mm, preferably 9mm to 21mm, but is not limited thereto.
The metal support frame 2 includes a longitudinal support frame, a runner (not shown) and a pillar. In the present embodiment, the longitudinal support frame uses C-shaped steel, but not limited thereto, and various cross-sectional shapes of steel, such as angle steel, channel steel, and the like, may be used. In the present embodiment, the outer wall panel 5 may be supported laterally using a longitudinal support frame, but the outer wall panel 5 may also be supported longitudinally using a lateral support frame.
The runner is positioned in the cavity of the vertical supporting frame. The flow channels include an upper flow channel (not shown) and a lower flow channel. The upper flow passage is arranged on the ceiling. The lower flow passage is arranged on the floor. The upper flow channel is formed of a downwardly opening rail material. The lower flow channel is formed of an upwardly opening rail material. When facing the indoor side or the outdoor side surface of the fire-resistant building panel, each flow passage is formed long in the left-right direction (substantially horizontal direction). In addition, the upper runner can be fixed on the surface of the ceiling or on the longitudinal supporting frame. The lower runner can be fixed on the surface of the floor or on the longitudinal supporting frame.
The support posts are a plurality of, each support post is formed of a generally saw tooth shaped rail material that is open to the sides. Each pillar is formed long in the vertical direction (substantially vertical direction). The end of each strut is secured to the flow passage. The upper end of each strut is inserted into and secured in the upper flow channel. The lower end of each pillar is inserted and fixed in the lower flow passage.
The heat-resistant sheet 4 may be formed of a plurality of sheets. In this case, the sheet material preferably contains a synthetic resin, a polyol, a flame retardant foaming agent, and the like. Further, the sheet preferably has a synthetic resin layer on a surface provided on the outer heat resistant plate 3, opposite to the outer wall panel 5. The synthetic resin may be blended with not only the synthetic resin layer but also other layers. The synthetic resin may be mixed with, for example, a polyol and a flame retardant foaming agent. The sheet may be formed into a sheet having a size larger than the outer dimension of the outer heat-resistant plate 3 by one turn, and may have a longitudinal side and a lateral side overlapped with each other.
Synthetic resins include melamine resins, acrylic resins, alkyl resins, vinyl chloride resins, vinyl acetate resins, urethane resins, epoxy resins, silicone resins, polyester resins, polyolefin/vinyl resins, vinyl acetate/vinyl ester of pizza acid copolymer resins, vinyl acetate/polyolefin resins, vinyl acetate/pizza acid/acrylic acid. The polyolefin may be polyethylene or the like, which is known in the art.
As the polyhydric alcohol, pentanediol, dipentadiol, tripentadiol, polypentadiol, etc. are exemplified.
As the flame retardant foaming agent, phosphates such as ammonium phosphate, ammonium polyphosphate, melamine phosphate, aluminum polyphosphate, magnesium polyphosphate and the like are preferably used, and sulfamates (sulfamates and the like), borates (ammonium borate and the like), expandable graphite and the like may be used. The above are all prior art.
The thickness of the heat-resistant sheet 4 is preferably 0.1mm or more and 5mm or less, more preferably 0.3mm or more and 3mm or less, and preferably 0.4mm or more and 1mm or less.
In order to improve the fire resistance by the foaming space 8, the volume of the heat-resistant sheet 4 after foaming is preferably 10 to 30 times the volume when not foaming. For example, by using the sheet-like heat-resistant sheet 4 having a thickness of 0.6mm in the foaming space 8 having a distance of 15mm between the outer wall panel 5 and the outer heat-resistant plate 3, the expansion ratio becomes 25 times, and the fire resistance can be relatively easily improved. When the sheet-like heat-resistant sheet 4 of 1.2mm is used as the expansion ratio 12.5, the fire resistance is further improved.
The foaming space 8 is a space for heating and expanding the heat-resistant sheet 4 in the event of a fire, and is generally used as a ventilation layer.
The external wall panel 5 may be a ceramic plate. The ceramic plate is a cured product of a hydraulic material containing cement. The external wall panel 5 is formed in a substantially flat plate shape, but may have a concave-convex pattern or a coating film on its surface, and may have design. The thickness of the external wall panel 5 may be formed to be 10mm to 30mm, but is not limited thereto. The shape of the outer wall panel 5 is also optional, but is formed in a rectangular plate shape in front view (in the case of viewing in the thickness direction of the outer wall panel 5). The recess 12 is provided at the upper end of the outer wall panel 5. The protruding portion 13 is provided at the lower end portion of the outer wall plate 5. The outer wall panels 5 of vertically adjacent construction are connected by fitting the concave portion 12 and the convex portion 13.
In the fire-resistant building panel of the present embodiment, a plurality of longitudinal support frames are provided on the upper side of the second base 16 via the first base 15. The plurality of longitudinal supports are arranged in the left-right direction according to a predetermined interval. The plurality of outer heat resistant plates 3 are attached to the front (outdoor) of the plurality of longitudinal support frames. The plurality of outer heat resistant plates 3 are arranged side by side in the vertical direction and the left-right direction. On the outer heat resistant plates 3 adjacent in the up-down direction, the lower ends of the outer heat resistant plates 3 on the upper side and the upper ends of the outer heat resistant plates 3 on the lower side are protruded and mounted. Further, on the outer heat resistant plates 3 adjacent in the left-right direction, the left end of the right outer heat resistant plate 3 and the right end of the left outer heat resistant plate 3 are protruded and mounted. Each outer heat resistant plate 3 is attached to the longitudinal support frame and fixed by fixing means such as screws and nails.
The outer heat resistant plates 3 arranged in the left-right direction are preferably provided in front of the longitudinal support frame. Therefore, even if the outer heat resistant plate 3 is deformed at the time of a fire and a gap is generated in the protruding portion, it is possible to prevent deterioration of the fire resistance due to being blocked by the longitudinal support frame. In addition, in the present embodiment, the rectangular outer heat resistant plate 3 may be installed laterally or longitudinally. The heat-resistant sheet 4 is provided outside the outer heat-resistant plate 3 fixed to the longitudinal support frame. The heat-resistant sheets 4 are arranged side by side up and down and left and right. Here, it is preferable to provide a mark on the surface of the heat-resistant sheet 4 as a reference for attaching the heat-resistant sheet 4 to the outside heat-resistant plate 3.
Preferably, the protruding portions of the lateral end portions 401 of the heat-resistant sheet 4 located at the vertical position between the lateral end portions of the outer heat-resistant plates 3 adjacent to the vertical direction overlap each other. Further, it is preferable that the protruding portion between the longitudinal edges of the outer heat resistant plates 3 adjacent to the left and right overlap the longitudinal edge end portions of the heat resistant sheets 4 located on the left and right.
The long sides of the rectangular outer heat-resistant plate 3 are not identical to the long sides of the rectangular heat-resistant sheet 4, and the long sides of the rectangular heat-resistant sheet 4 can be substantially the same size from the long sides of the rectangular outer heat-resistant plate 3. At this time, the upper end portion of the rectangular heat-resistant sheet 4 is located above the upper long side of the rectangular outer heat-resistant plate 3, and the lower end portion of the rectangular heat-resistant sheet 4 is located below the lower long side of the rectangular outer heat-resistant plate 3.
In the case of attaching the lowermost rectangular heat-resistant sheet 4, the long side of the lower side of the rectangular outer heat-resistant plate 3 may be aligned with the long side of the lower side of the rectangular heat-resistant sheet 4, and the rectangular heat-resistant sheet 4 may be viewed only above the long side of the upper side of the rectangular outer heat-resistant plate 3. The base drain 9 is provided at the outdoor side of the lowermost heat-resistant sheet 4, and the waterproof layer 10 is fixed at the outdoor sides of the heat-resistant sheet 4 and the base drain 9 by a fixing means such as glue.
The heat-resistant sheet 4 is constructed upward from the lower stage, so that the protruding portion can be overlapped in the front (surface side), and in particular, the fire resistance of the protruding portion between the vertical sides of the outer heat-resistant plate 3 adjacent to each other in the upper-lower direction can be improved. In the present embodiment, the protruding portions of the short sides of the rectangular outer heat resistant plate 3 and the protruding portions of the short sides of the rectangular heat resistant sheet 4 are offset in the left-right direction, but the present utility model is not limited thereto, and the protruding portions may be made substantially uniform in the front-rear direction.
After the heat resistant sheet 4 is completely installed on the outside heat resistant plate 3, the waterproof layer 10 is installed outside the room of the heat resistant sheet 4. The waterproof layer 10 is a sheet material that does not pass through water droplets. The waterproof layer 10 is installed on the entire surface of the plurality of heat resistant sheets 4. A plurality of fasteners 11 are provided on the outside of the waterproof layer 10 (near the outside of the house, hereinafter referred to as "location"). Is secured to the longitudinal support frame by fasteners such as screws.
The exterior wall panel 5 is attached to the outside of the waterproof layer 10 by fasteners 11. A plurality of exterior wall panels 5 are arranged together and each exterior wall panel 5 is secured by a plurality of fasteners 11. The upper end of the outer wall panel 5 is hooked and fixed to the fastener 11 provided on the upper side of the outer wall panel 5, and the lower end of the outer wall panel 5 is hooked and held to the fastener 11 provided on the lower side of the outer wall panel 5. Further, the side wall panels 5 adjacent to each other vertically are connected to the concave portion 12 by the solid engagement of the convex portion 13. The joint material is disposed between the side wall panels 5 adjacent in the left-right direction. The sealing material is disposed outside the joint material. The base drain 9 is disposed below the lowermost exterior wall panel 5. A ventilation layer (foaming space 8) is formed inside the outer wall panel 5. A ventilation layer (foaming space 8) is formed between the rear surface (indoor side surface) of the exterior wall panel 5 and the front surface (outdoor side surface) of the waterproof layer 10.
Preferably, in the front view, the positions of the adjacent portions of the outer wall panels 5 adjacent in the up-down direction and the positions of the adjacent portions of the outer heat resistant plates 3 adjacent in the up-down direction do not overlap. Further, it is preferable that the positions of the sealing material between the outer wall panels 5 adjacent in the left-right direction and the positions of the adjacent portions of the outer heat resistant plates 3 adjacent in the left-right direction are offset without overlapping in the front view. In this case, even if flames intrude into the joints of the adjacent external wall panels 5 from the outside of the room, flames hardly intrude directly into the adjacent portions of the adjacent outer heat resistant panels 3, and thus fire resistance can be improved. In the front view, the joint of the side fascia 5 adjacent in the left-right direction and the protruding portion of the outer heat resistant plate 3 adjacent in the left-right direction preferably coincide with the longitudinal support frame, but the joint and the protruding portion may coincide with the same longitudinal support frame, and the joint and the protruding portion may coincide with different longitudinal support frames.
The runner and the plurality of struts are disposed in a room of the longitudinal support frame. Among the flow passages, an upper flow passage is provided on the ceiling, and a lower flow passage is provided on the floor. The upper end of each strut is inserted into and secured in the upper flow channel. The lower end of each pillar is inserted and fixed in the lower flow passage. The plurality of inner heat resistant plates 1 are fixed to at least one of the flow path and the plurality of struts by a fixing tool for the airtight sheet. The plurality of inner heat resistant plates 1 are arranged side by side in the vertical direction and the left-right direction. The ends of the inner heat resistant plates 1 adjacent in the vertical direction and the left-right direction are arranged to protrude from each other. In addition, the upper runner can be fixed on the surface of the ceiling or on the longitudinal supporting frame. The lower runner can be fixed on the surface of the floor or on the longitudinal supporting frame.
In the fireproof building wallboard formed as described above, by providing the heat-resistant sheet 4, heating is performed from the outdoor side of the exterior wallboard 5 at the time of a fire, and by foaming and expanding the heat-resistant sheet 4, the foaming space 8 is formed in the ventilation layer (foaming space 8). The ventilation layer serves as a foaming space 8 for foaming and expanding the heat-resistant sheet 4. Accordingly, flame and heat entering from the outside to the inside can be reduced by the heat insulating effect and the heat insulating effect of the foam-expanded heat-resistant sheet 4, and thus, fire resistance can be improved. Further, by providing the heat-resistant sheet 4 behind the external wall panel 5, the heat-resistant sheet 4 does not require water resistance. Further, since the heat-resistant sheet 4 is a thin material in the absence of a fire, the ventilation layer (the foaming space 8) is not blocked in normal conditions, and the dimension of the fire-resistant building panel in the front-rear direction (the dimension from the outer panel 5 to the outer heat-resistant plate 3) is also less likely to be larger than the conventional dimension. Further, the heat resistant sheet 4 is relatively lighter than the outer heat resistant plate 3, so that the burden in construction can be reduced. Further, in the fireproof building wallboard, by providing the heat-resistant sheet 4, in the event of a fire, the heat-resistant sheet 4 heats up, and the heat-resistant sheet 4 foams and expands, thereby forming the foaming space 8 in the ventilation layer (foaming space 8). Accordingly, flame and heat discharge from the indoor to the outdoor can be reduced by the heat insulating effect and the fire insulating effect of the foam-expanded heat-resistant sheet 4, and thus fire resistance can be improved.
In the present embodiment, the heat insulating material is not used, but the heat insulating material may be provided between the inner heat resistant sheet 4 and the outer heat resistant plate 3 as needed.
Fig. 4 and 5 show a fire-resistant building panel near an opening. The opening is a cut-out in a building wall or the like. The openings are used for lighting, ventilation, etc. Such as a door or window, etc.
Fig. 4 and 5, on the other hand, illustrate a fire-resistant building panel adjacent the roof 14. The eave top 14 is the ceiling of the eave portion.
As described below, the fire-resistant building panel according to the present embodiment is particularly suitable for the opening portion and the roof eave 14 portion.
In fire resistant building panels, exterior panels 5 are installed using fasteners 11. However, the fastener 11 may not be used, such as near the opening shown in fig. 4 and 5, near the roof 14 shown in fig. 3, and so on.
For example, in the vicinity of the opening shown in fig. 4 and 5, it may be necessary to cut the side fascia 5 along the periphery of the opening. In this case, the concave portion 12 or the convex portion 13 provided in the side fascia 5 may disappear with cutting. In this way, when the recess 12 or the protrusion 13 disappears, the fastener 11 becomes unusable.
Similarly, near the eave top 14 as shown in fig. 3, it may be necessary to cut the upper portion of the exterior wall panel 5 to prevent touching the eave top 14. In this case, the concave portion 12 provided in the side fascia 5 may disappear with cutting. In this way, the fastener 11 becomes unusable when the recess 12 disappears.
Therefore, in the present embodiment, even if the fastener 11 is not used, the exterior wall panel 5 can be mounted on the exterior heat resistant plate 3 as follows. Further, the external wall panel 5 may be installed on the basis of securing a foaming space 8 required for foaming when heating a fire or the like.
The fire-resistant building panel according to the present embodiment includes an outer panel 5, an outer heat-resistant plate 3, a heat-resistant sheet 4, a first partition plate 6, and fixing means.
Here, the exterior wall panel 5 of the present embodiment is the same as the exterior wall panel 5 of fig. 1. In addition, as described above, the exterior wall panel 5 of the present embodiment may be cut to a desired size. For example, the concave portion 12 or the convex portion 13.
The outer heat resistant plate 3 and the heat resistant sheet 4 of the present embodiment are the same as the outer heat resistant plate 3 and the heat resistant sheet 4 of fig. 1. Further, when the waterproof layer 10 is provided on the outdoor side of the heat resistant sheet 4, it is also described as the heat resistant sheet 4.
The first partition plate 6 is a plate-like member. The first partition plate 6 is interposed between the side fascia 5 and the heat resistant sheet 4. The outdoor side surface of the first partition plate 6 is in contact with the rear surface of the side fascia 5. The indoor surface of the first partition plate 6 is in contact with the surface of the heat-resistant sheet 4. Therefore, the first partition plate 6 generally has a function of forming a ventilation layer (foaming space 8) between the outer wall plate 5 and the heat-resistant sheet 4. When the external wall panel 5 is installed, the first partition plate 6 may be temporarily fixed on the surface of the heat-resistant sheet 4 by a suitable method (e.g., adhesion).
The first partition plate 6 is made of a material that softens or melts below the foaming start temperature of the heat-resistant sheet 4. However, the first partition plate 6 does not soften or the like at normal temperatures (for example, summer air temperature). Thus, at normal temperature, the first partition plate 6 continues to secure the ventilation layer (foaming space 8) between the outer wall plate 5 and the heat-resistant sheet 4. Materials that soften or melt below the foaming initiation temperature include plastics such as polypropylene, polyethylene and polyethylene terephthalate, and low melting point metals. Low melting point metals include various metals for solder and alloys thereof.
The temperature becomes high due to fire or the like, and after the first partition plate 6 is softened or melted, the heat resistant sheet 4 is foamed to form a foaming space 8. Therefore, a portion where the thickness of the foaming space 8 is reduced is hardly generated near the first partition plate 6, and the fire resistance is more stable. The shape of the first partition plate 6 is rectangular, but the shape and size of the first partition plate 6 in front view are not particularly limited.
The fixing means fix the outer wall panel 5 to the outer heat resistant plate 3. That is, the fixing tool is a fixing tool (fastening fixing tool) for directly fixing the exterior wallboard 5 to the outside heat resistant plate 3. The fixing means include screws, nails, and the like. The fixing means passes through the external wall panel 5, the first partition plate 6 and the heat-resistant sheet 4. The tip of the fixing tool is stuck on the outer heat resistant plate 3. The tip of the holding tool can be tied to the longitudinal support. The fixing tool is driven from the surface (outdoor side surface) of the exterior wall plate 5. The first spacer plate 6 is present on the rear side of the external wall panel 5 at the location where the fixing tool is inserted. Therefore, the first partition plate 6 also has a function of suppressing the outer wall plate 5 from tilting in the house and supporting the outer wall plate 5 when driving the fixing tool from the surface of the outer wall plate 5.
In the present embodiment, even where the external wall panel 5 is cut and used, the foaming space 8 required for the foam of the heat-resistant sheet 4 can be ensured at the time of a heating fire or the like, and good fire resistance can be easily obtained after the foam of the heat-resistant sheet 4. That is, at the time of fire occurrence, the first partition plate 6 is softened or melted, so that the foaming space 8 is also formed at the position where the first partition plate 6 originally exists. That is, in the event of a fire, the first partition plate 6 does not interfere with expansion caused by foaming of the heat-resistant sheet 4, and a foaming space 8 having a sufficient thickness can be formed. On the other hand, even if the outer wall panel 5 is deformed, the outer wall panel 5 may continue to fix the outer wall panel 5 to the outer heat resistant plate 3 to maintain the foaming space 8 between the outer wall panel 5 and the outer heat resistant plate 3.
The fireproof building panel according to the present embodiment is particularly effective when the position near the opening and the position near the eave are formed, but is effective when the position is formed at other positions.
Example 2:
the embodiment provides a composite fireproof building wallboard, which has the following technical characteristics in addition to the technical scheme of the embodiment.
In this embodiment, the same reference numerals are given to the same configurations as in embodiment 1, and detailed description thereof may be omitted.
In the above-described fire-resistant building panel shown in fig. 1, the exterior panel 5 is installed by using a plurality of tab fasteners 11. However, in a high-rise building, the higher the wind pressure variation generated in the exterior wall panel 5 is, the more firmly the exterior wall panel 5 needs to be installed.
The external wall panel 5 is mounted by means of long sheet fasteners 18.
The long sheet-like fastener 18 has the same length as the outer wall panel 5, and can be supported at the concave portion 12 and the convex portion 13 of the outer wall panel 5. Further, in one building, the tab fastener 11 and the long tab fastener 18 may be used simultaneously, and the tab fastener 11 may be used in the next floor of the building and the long tab fastener 18 may be used in the upper floor of the building.
The first spacer plate 6 can also be used for the upper floors of a building. The first partition plate 6 is disposed near the center of the vertical width of the outer wall plate 5, and passes through the outer wall plate 5 by a fixing tool, and the first partition plate 6 and the heat resistant sheet 4 are fixed to the outer heat resistant plate 3 or the longitudinal support frame. Therefore, the first partition plate 6 also has the function of preventing the outer wall plate 5 from tilting inward when the fixing tool is driven from the surface of the outer wall plate 5, supporting the outer wall plate 5, and protecting the outer wall plate 5 from large wind pressure variations generated in the upper outer wall plate 5.
In this example, as in example 1, even when the external wall panel 5 is used as the upper layer, the foaming space 8 required for foaming the heat-resistant sheet 4 at the time of heating in a fire or the like can be ensured, and good fire resistance can be easily obtained after the heat-resistant sheet 4 is foamed. That is, at the time of fire occurrence, the first partition plate 6 is softened or melted, so that the foaming space 8 is also formed at the position where the first partition plate 6 originally exists. That is, at the time of a heating fire or the like, the first partition plate 6 does not interfere with expansion caused by foaming of the heat-resistant sheet 4, and thus a foaming space 8 having a sufficient thickness is formed. On the other hand, even if the outer wall panel 5 is deformed, the outer wall panel 5 may continue to fix the outer wall panel 5 to the outer heat resistant plate 3 to maintain the foaming space 8 between the outer wall panel 5 and the outer heat resistant plate 3.
Example 3:
the embodiment provides a composite fireproof building wallboard, which has the following technical characteristics in addition to the technical scheme of the embodiment.
In this embodiment, the same components as those in embodiment 1 and embodiment 2 are given the same reference numerals in the drawings, and detailed description thereof is omitted.
A plurality of longitudinal support frames are provided on the upper side of the second base 16 via the first base 15. The plurality of longitudinal supports are arranged in the left-right direction via predetermined intervals. Furthermore, two or more longitudinal support frames may be combined.
The outer heat resistant plate 3 is arranged outside the longitudinal support frame. The heat resistant sheet 4 is disposed outside the outer heat resistant plate 3.
The first partition plate 6 is supported by pressing the heat resistant sheet 4 against the outer heat resistant plate 3.
The first partition plate 6 is disposed near the center of the vertical width of the outer wall plate 5, and passes through the outer wall plate 5 by a fixing tool, and the first partition plate 6 and the heat resistant sheet 4 are fixed to the outer heat resistant plate 3 or the longitudinal support frame.
The second partition plates 17 are provided to be located at upper and lower portions of the vertical width of the side wall plate 5 to assist the first partition plates 6. The second partition plate 17 has, for example, a pillar shape, and is mounted on the heat-resistant sheet 4 by an adhesive. That is, since the outer panel 5 is not fixed by the fixing tool like the first partition plate 6, the mounting position can be arbitrarily selected.
The exterior wall panel 5 is attached to the outdoor side of the heat-resistant sheet 4 by a fastener 11. A plurality of exterior wall panels 5 are arranged together and each exterior wall panel 5 is secured by a plurality of fasteners 11. That is, the upper end of the exterior wall panel 5 is hooked and fixed to the fastener 11 provided at the upper side thereof, and the lower end of the exterior wall panel 5 is hooked and fixed to the fastener 11 provided at the lower side thereof. The vertically adjacent external wall panels 5 are connected by the engagement of the convex portion 13 and the concave portion 12.
The fixing means is fixed to the outer heat-resistant plate 3 through the first partition plate 6.
The fixing means passes through the external wall panel 5, the first partition plate 6 and the heat-resistant sheet 4 and is fixed to the outside heat-resistant plate 3 or the longitudinal support frame. Therefore, the first partition plate 6 also has the function of suppressing the outer wall plate 5 from tilting inward when the fixing tool is driven from the surface of the outer wall plate 5, supporting the outer wall plate 5, and protecting the outer wall plate 5 from large wind pressure variations generated in the upper outer wall plate 5. Further, by attaching the second partition plate 17 to a position where it is difficult to fix the first partition plate 6, the function of protecting the side fascia 5 can be further improved.
In this example, as in examples 1 and 2, even when the external wall panel 5 is used as the upper layer, the foaming space 8 required for foaming the heat-resistant sheet 4 at the time of heating in a fire or the like can be ensured, and excellent fire resistance can be easily obtained after foaming the heat-resistant sheet 4. That is, at the time of fire occurrence, the first and second partition plates 6 and 17 are softened or melted, so that the foaming space 8 is also formed at the position where the first and second partition plates 6 and 17 originally exist. That is, at the time of a heating fire or the like, the first and second partition plates 6 and 17 do not interfere with expansion caused by the foam of the heat-resistant sheet 4, and thus a foam layer having a sufficient thickness is formed. On the other hand, even if the outer wall panel 5 is deformed, the outer wall panel 5 may continue to fix the outer wall panel 5 to the outer heat resistant plate 3 to maintain the foaming space 8 between the outer wall panel 5 and the outer heat resistant plate 3.
The embodiments of the present application and the features of the embodiments may be combined without conflict, and the present application is not limited to the specific embodiments described above, which are merely illustrative, not restrictive, and many forms may be made by those of ordinary skill in the art, without departing from the spirit of the present application and the scope of the claims, which are also within the scope of the present application.
