Japanese Patent Application Publication No. 2002-194835 JP 2021-120523 Publication Special table 2017-525641 publication JP2021-167264A

BACKGROUND OF THE INVENTION Glass partition walls installed in offices, residences, etc. are required to have a certain fire-retardant performance so that people can evacuate in the event of a fire. Additionally, even if a fire breaks out indoors, the glass partition walls maintain their strength for a certain period of time, which delays the fall of the smoke generated by the fire, allowing time for evacuation and reducing the number of evacuation stairs. It is possible to reduce the cost of taking measures such as increasing the number of people.
For example, in the case of a fireproof glass panel with a plate-like mounting structure described in Patent Document 1, two T-shaped metal fittings are placed facing each other in an H-shape, and a back-up material is inserted into the formed groove. The edges of the glass panel are clamped. As a result, two T-shaped fittings are installed continuously from the ceiling to the floor along the edge of the fireproof glass panel, increasing bending rigidity and preventing the fireproof glass panel from bending. The purpose is to ensure strength.

However, in recent years, there has been an increasing need for glass partition devices that have high fire prevention performance and good design, and are easy to install. As in Patent Document 1, since the T-shaped connecting fittings are provided from the ceiling to the floor at the end of the glass panel, a problem arises in design. Furthermore, the T-shaped metal fittings for holding the glass panels together are installed along both sides between the respective fireproof glass panels, and there is a problem in that the construction requires many man-hours and costs.

On the other hand, the glass partition walls described in Patent Documents 2 to 4 use point fixtures at specific locations in the abutment areas of adjacent glass plates to suppress warpage of the glass plates, and are devised to miniaturize the connecting fittings. doing. In this case as well, the connecting fittings spoil the aesthetic appearance of the room, and there is still a problem with the design.
Furthermore, regarding the method of fixing the glass panels together, it is necessary to install point-fixed connecting fittings from both sides between each glass panel, which poses problems in terms of workability.

The present invention has been made to solve the above-mentioned drawbacks, and its purpose is to provide a glass partition wall that has fireproof performance, does not impair the beauty of the entire room, and has an excellent design.
Another object of the present invention is to provide a glass partition wall in which glass panels can be easily connected to each other and has excellent workability.

(1)
A partition wall according to one aspect is a partition wall that includes a glass panel and a holder that holds the glass panel, the holder having a pair of opposing walls and a bottom surface, and a cross section that is open to the glass panel side. It is U-shaped, and may include a fixing portion between the edge surface and the bottom surface of the glass panel, and may have a deformation absorbing space between the opposing wall and the glass panel.

In this case, since the holder is provided with a deformation absorbing space, it is possible to absorb expansion or deformation of the glass panel due to heat during a fire. In particular, if a fire breaks out on one side of a partition wall and the flames hit one side of the glass panel, the glass panel will be significantly thermally deformed in one direction, causing the fixing part that fixes the glass panel to the holder to break, causing the glass panel to break. The thermal deformation of the panel can be absorbed by the deformation absorbing space. Therefore, even if the glass panel undergoes thermal expansion, damage to the glass panel can be prevented.
Furthermore, even if most of the fixing parts break and the glass panel is about to fall, the glass panel continues to be held by the holder because the glass panel is supported by the opposing wall of the holder.
Therefore, even if a fire occurs on one side of the partition wall, the flames will be prevented from erupting beyond the partition wall for a certain period of time, and the outflow of flammable gas will be prevented, thereby preventing the flame from spreading beyond the partition wall. Damage such as cracks and the occurrence of gaps through which flame can pass can be prevented. Furthermore, since the glass is prevented from breaking and falling in the event of a fire, it is possible to retain smoke from the fire room toward the evacuation route for a certain period of time, thereby ensuring safety during evacuation.
Furthermore, since the partition wall is made of glass panels, it has an excellent design and can bring a sense of openness to the space in which the partition wall is installed.

(2)
In the partition wall according to one aspect of the second aspect of the invention, the fixing portion may be made of a plastic material having a tensile adhesive strength of 1.5 N/mm ² or more and 3.2 N/mm ² or less. .

Thereby, the glass panel and the holder are held with a predetermined strength in the fixing portion. Further, when the glass panel is thermally deformed significantly in one direction due to a fire, the holding state of the fixing portion is released, and the expansion and deformation of the glass panel due to heat is absorbed by the deformation absorbing space of the holder.
Moreover, since the deformation of the glass panel is absorbed by the deformation absorbing space, stress is released, so that damage to the glass panel can be prevented.

(3)
In one aspect of the partition wall according to the third invention or the partition wall according to the second invention, the fixing portion may be made of a resin having a heat resistance temperature of −50° C. or higher and 150° C. or lower.

As a result, when a predetermined temperature is reached in the event of a fire, the strength of the resin decreases and the holding state of the fixing part is easily released. Thereby, deformation of the glass panel due to heat is absorbed by the deformation absorbing space of the holder.
Furthermore, since the expansion of the glass panel is absorbed by the deformation absorbing space, stress is released and damage to the glass panel can be prevented.

(4)
The partition wall according to a fourth invention is the partition wall according to any one of the first aspect to the third invention, wherein the deformation absorbing spaces are provided on both sides of the glass panel, and the edge surface of the glass panel is located at the center of the bottom surface. It may be fixed at the section.

Thereby, even if a fire occurs on either side of the glass panel, thermal deformation of the glass panel can be reliably absorbed. It is assumed that partition walls installed indoors may occur on either side of the glass panel. When the holding state of the fixing part is released in the event of a fire, the expansion and deformation of the glass panel due to heat can be absorbed by the deformation absorbing spaces on both sides of the glass panel.
Because the glass panel curves convexly toward the side where the fire is occurring, both sides of the glass panel must absorb expansion and deformation in the event of a fire. Therefore, even when a fire occurs on either side of the glass panel, it is possible to cope with the curvature of the glass panel.

(5)
In the partition wall according to the fifth invention, in the partition wall according to any one of the first to fourth inventions, the thickness of the deformation absorbing space may be 1.6 times or more the thickness of the glass panel.

Thereby, even if one side of the glass is exposed to high temperatures due to fire flames, large thermal deformation can be reliably absorbed.
Note that the thickness of the deformation absorbing space here corresponds to the distance obtained by subtracting the thickness of the glass panel from the distance between the inner surfaces of the pair of opposing walls. The deformation absorbing space may be provided on one side or both sides of the glass panel, but when the deformation absorbing space is provided on both sides, the thickness thereof is the total value.

(6)
A partition wall according to a sixth invention is a partition wall according to any one of the first to fifth inventions, wherein the holder is a frame of a glass panel including a vertical column and a horizontal column, and the deformation absorption space is , may be provided only on vertical columns.

Thereby, the deformation of the glass panel in the event of a fire is absorbed by the vertical columns of the holder, and the horizontal columns continue to fix the edges of the glass. Therefore, in the event of a fire, flames, smoke, etc. are prevented from leaking through the gap between the horizontal column and the glass panel.
In particular, most of the high-temperature smoke and gas travels from the ceiling, so by keeping the horizontal pillars fixed, the partition between the ceiling and the glass panel is maintained, and a large amount of smoke and gas leaks into the hallway, which serves as an evacuation route. It is possible to prevent people from leaving and ensure safety during evacuation.

(7)
A partition wall according to a seventh invention is a partition wall according to any one of the first aspect to the sixth invention, wherein the glass panel is composed of a plurality of connected plate glasses, and the edge surfaces of the connected plate glasses are connected to each other. A section may be provided.

If the glass panel is huge, such as a plurality of glass plates connected together, the amount of deformation of the glass panel will be large when a fire occurs. In this way, if the amount of deformation of the glass panel is large, the fixing part on the holder side will break, so the deformation absorption space absorbs the thermal deformation of the glass panel, preventing the entire glass panel from being damaged and falling over. be able to.
Furthermore, since the glass panel is made up of multiple sheets of glass, the size of the partitioned space can be adjusted. Furthermore, when enlarging the space to be partitioned, even if the area of the glass panel increases, the space can feel open and the interior design can be maintained.

(8)
In the partition wall according to the eighth invention, in the partition wall according to the seventh invention, the connecting portion may be made of a sealing resin that is transparent and has better fire resistance than the fixed portion.

As a result, the sealing resin of the fixing portion is actively broken in the event of a fire, so that the connected state of the glass plates can be reliably maintained. Therefore, in the event of a fire, it is possible to prevent flames from erupting from the connected parts of the connected glass plates, prevent flames from igniting due to the outflow of flammable gas, and prevent damage such as cracks and the creation of gaps that allow flames to pass through. I can do it. This prevents flames and smoke from leaking from the fire room into the hallway or other rooms, ensuring safety during evacuation.
Furthermore, since the connecting portion is made of transparent sealing resin, it is possible to create a sense of openness in the space even when a plurality of glass plates are connected.

(9)
In the partition wall according to the ninth invention, in the partition wall according to the seventh invention, the connecting part may be transparent and thicker than the fixed part.

As a result, the sealing resin of the fixing portion is actively broken in the event of a fire, so that the connected state of the glass plates can be reliably maintained. Therefore, in the event of a fire, it is possible to prevent flames from erupting from the connected parts of the connected glass plates, prevent flames from igniting due to the outflow of flammable gas, and prevent damage such as cracks and the creation of gaps that allow flames to pass through. I can do it. This prevents flames and smoke from leaking from the fire room into the hallway or other rooms, ensuring safety during evacuation.
Furthermore, since the connecting portion is made of transparent sealing resin, it is possible to create a sense of openness in the space even when a plurality of glass plates are connected.

(10)
In the building according to another aspect, the partition wall according to any one of the first to ninth aspects of the invention may be installed.

As a result, when the glass partition wall is installed in a building, it is possible to provide an interior with excellent fire prevention performance and design.

(11)
A partition wall construction method according to another aspect is a partition wall construction method according to any one of the seventh to ninth inventions, comprising: a connecting step of connecting a plate glass and a holder at a fixing portion; The method may also include a sealing step of connecting the edge surface of the fixed glass plate to the edge surface of another glass plate using a sealing resin.

Thereby, adjacent glass plates and the holder and the glass plate can be fixed with only the sealing resin. Therefore, since there is no need to install a metal member or the like between adjacent glass plates, the construction can be easily carried out, and furthermore, the design can be maintained.

It is a typical perspective view showing an example of the state where a partition wall was installed. FIG. 2 is a schematic cross-sectional view of the partition wall of FIG. 1 taken in a direction parallel to the ceiling. FIG. 2 is a schematic cross-sectional view of the partition wall in FIG. 1 taken in a direction perpendicular to the ceiling. FIG. 3 is a partially enlarged view of FIG. 2 and a schematic diagram for explaining the situation at the time of a fire.

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated.

[This embodiment]
FIG. 1 is a schematic perspective view showing an example of an installed state of a partition wall according to an embodiment of the present invention. Moreover, FIG. 2 is a schematic cross-sectional view when the partition wall of FIG. 1 is cut in a direction parallel to the ceiling. FIG. 3 is a schematic cross-sectional view of the partition wall of FIG. 1 taken in a direction perpendicular to the ceiling. FIG. 4(a) is a partially enlarged view of FIG. 2, and FIG. 4(b) is a schematic diagram for explaining the state of the fixed portion in the event of a fire.
As illustrated in Fig. 1, the building in which the partition wall of this embodiment is installed has excellent fire prevention performance while maintaining the aesthetic appearance of the entire room. It is possible to secure time and partition space for people inside the building to evacuate. In addition, since the main partition wall partitions the space with glass panels, the location of the fire can be determined and evacuation can be facilitated.

(Partition wall 10)
As shown in FIG. 1, the partition wall 10 of this embodiment can partition an internal space such as an office or a residence using connected glass panels.
The periphery of the glass panel of this embodiment is provided with a holder 100 consisting of a horizontal column 100a installed horizontally to the ceiling 500, and a vertical column 100b installed vertically to the ceiling 500, A glass panel is held by a holder 100.
The horizontal columns 100a are arranged in pairs, one installed on the ceiling 500 and the other installed on the floor 600, and the vertical columns 100b are installed on the wall 700 or the like. Note that the vertical column 100b may be fixed to a wall, or may be fixed to a square pipe or the like that holds a door.

(Glass panel)
The glass panel held by the holder 100 partitions a space, and is composed of one or more glass plates 200. In addition, when connecting a plurality of glass plates 200, the edge surfaces 210 are connected using a connecting part 400, which will be described later.
The number of sheet glasses 200 used in the glass panel may be one or a plurality of sheets connected, and may be, for example, from 2 to 10, preferably from 2 to 4. Thereby, it is possible to achieve both fire prevention performance and space division.

Although the size of the plate glass 200 is not particularly limited, the width of the plate glass 200 can be, for example, 0.5 m or more and 1.5 m or less, and preferably 0.8 m or more and 1.2 m or less. Further, the height of the plate glass 200 can be, for example, 2 m or more and 3.4 m or less, and preferably 2.7 m or more and 3.4 m or less. Further, the thickness of the plate glass 200 can be, for example, 5 mm or more and 30 mm or less, and preferably 10 mm or more and 20 mm or less.
Moreover, although double-layered glass can be used for the plate glass 200, from the viewpoint of sufficiently absorbing thermal deformation in the deformation-absorbing space 111, it is preferable to use single-layered glass.

(Holder 100)
The holder 100 is composed of a horizontal column 100a and a vertical column 100b.
Among these, the vertical columns 100b are installed on a wall surface or the like to hold the vertical ends of the glass panel, and usually hold the short sides of the glass panel in pairs.
As shown in FIG. 2, the vertical column 100b of this embodiment has a U-shaped cross section and has a pair of opposing walls 110 and a bottom surface 112. The end portion of the glass plate 200 is arranged so as to fit into the U-shaped cross section, and a fixing portion 300 (described later) is provided between the edge surface 210 and the bottom surface 112 of the glass plate 200, so that the glass plate 200 is held. be done.
Further, a deformation absorbing space 111, which will be described later, is provided between the opposing wall 110 of the vertical column 100b and the glass plate 200, so that deformation of the glass plate 200 can be absorbed.

Further, the horizontal columns 100a are installed on a ceiling surface or the like to hold the ends of the glass panels in the left and right direction, and usually hold the long sides of the glass panels in pairs.
As shown in FIG. 3, the horizontal column 100a of this embodiment has a U-shaped cross section and has a pair of opposing walls 110 and a bottom surface 112. Then, the end portions of the glass plate 200 are arranged so as to fit inside the U-shaped cross section, and the glass plate 200 is fixed.
In the horizontal column 100a of this embodiment, a pair of opposing walls 110 are provided with a sealing material to fix the plate glass 200 from both sides and restrict movement. Therefore, even in the event of a fire, the horizontal column 100a of this embodiment continues to hold the glass plate 200, prevents the glass plate 200 from falling, and prevents the spread of flame. Moreover, since the movement of the glass plate 200 is restricted, the stress of the thermal deformation of the glass plate 200 is transmitted to the vertical column 100b side, and the fixation of the fixing portion 300 on the vertical column 100b side is released, so that the thermal deformation is actively absorbed.

The holder 100 in this embodiment is a frame of a glass panel including vertical columns 100b and 100a. The holder 100 shown in FIG. 2 is an example formed by deforming a single metal plate. The material of the holder 100 can be, for example, steel or aluminum, and preferably steel.
The length of the opposing wall 110 (length of protrusion from the bottom surface 112) can be 5 mm or more and 40 mm or less, and preferably 8 mm or more and 20 mm or less. Further, the separation distance between the pair of opposing walls 110 can be 8.0 mm or more and 150 mm or less, and preferably 30 mm or more and 80 mm or less. In the event of a fire, when the fixing part 300 is released and the edge surface 210 of the plate glass 200 is separated from the fixing part 300, the opposing wall 110 forming the holder 100 supports the glass panel so that it does not fall.
The vertical column 100b is fixed to a wall or the like by a screw 710 and a locking member 720 that is substantially U-shaped and faces leftward in side view and is arranged on the back side of the wall.

The horizontal columns 100a include those fixed to the ceiling 500 and those fixed to the floor 600. The horizontal column 100a fixed to the ceiling 500 is fixed to the ceiling 500 by a bolt 510 and a locking member 520 which is arranged on the back side of the ceiling 500 and has a generally upward U-shape when viewed from the side. Thereby, the ceiling 500 is firmly fixed so as to be sandwiched therebetween.
The horizontal column 100a fixed to the floor 600 is fixed to the floor 600 by an anchor bolt 610 installed on the bottom surface 112.

The horizontal column 100a does not have a deformation absorbing space 111, and the movement of the glass panel in the front-back direction is supported by an elastic member 220 installed along the entire length of the glass panel between the front and rear surfaces of the glass panel and each opposing wall 110. is suppressed and maintained. As the elastic member 220, a rubber packing or the like can be used. Further, as a method of holding the glass panel, conventionally known sealing, gasket, glazing bead, glazing channel, etc. may be employed.

(Fixed part 300)
As shown in FIGS. 2 and 4, the fixing portion 300 provided on the vertical column 100b fills the space between the edge surface 210 and the bottom surface 112 of the glass panel, and at the same time joins the mutually opposing end surfaces. As an example of the fixing part 300, it can be fixed with sealing resin A or double-sided tape.
The sealing resin A preferably has a heat resistance temperature (JIS K5600-6-3) of, for example, -50°C or higher and 150°C. Further, it is preferable that the tensile adhesive strength (JIS A1439) is, for example, 1.5 N/mm ² or more and 3.2 N/mm ² or less.
As a result, as shown in FIG. 4(a), the glass panel is normally fixed, but in the event of a fire, the deformation of the plate glass 200 is largely transmitted to the edge, as shown in FIG. 4(b), so the fixing part 300 is held. The condition is canceled. Therefore, stress on the glass panel deformed by heat can be released, and breakage or falling of the glass panel can be prevented. Sealing resin A may or may not have fire resistance.
Further, the thickness of the sealing resin A in the glass panel thickness direction is preferably equal to or less than the glass panel thickness. Further, the width between the glass edge surface 210 and the bottom surface 112 can be 3 mm or more and 20 mm or less, and preferably 5 mm or more and 15 mm or less. This provides excellent workability, and while the bottom surface 112 and the glass panel are sufficiently fixed, the holding state of the fixing portion 300 is released in the event of a fire.

As shown in FIG. 2, the glass plate 200 whose one end is fixed to the vertical column 100b can be connected to another glass plate 200 at the other end, and a connecting portion 400 is provided on the face 210 of the other end. .
The sealing resin A of the fixed part 300 and the sealing resin B of the connecting part 400 may be the same or different. If the same resin is used for sealing resins A and B, the amount or thickness applied to the fixing part 300 may be smaller than that applied to the connecting part 400. As a result, the fixed state of the fixed part 300 is preferably released earlier than the connecting part 400.
Further, when different resins are used for the sealing resins A and B, it is preferable that the heat resistance, breaking strength, and/or tensile adhesive strength of the fixing part 300 be smaller than that of the connecting part 400. As a result, the fixed state of the fixed part 300 is preferably released earlier than the connecting part 400.

As shown in FIG. 4(b), in the event of a fire, the entire glass panel is thermally deformed and the position of the end of the glass panel is largely displaced, but the amount of deformation of the holder 100 is small. Therefore, in the event of a fire, the displacement of the fixed part 300 will be greater than the displacement of the connecting part 400, so even if the same sealing resin is applied to the fixed part 300 and the connecting part 400 with the same thickness, The holding state of the fixed part 300 is released earlier than that of the connecting part 400.
Then, the fixed state of the fixed part 300 is released first, and the stress caused by the deformation of the glass plates 200 is released by the deformation absorbing space 111, so that the connecting part 400 can maintain the connected state for a certain period of time even in the event of a fire. becomes.

As the resin used for the sealing resin A or B, epoxy resin, acrylic resin, polyamide resin, urethane resin, silicone resin, polysulfide resin, modified silicone resin, etc. can be used. Among these, it is preferable to use silicone resin from the viewpoint of adhesive strength and design.
Further, in applying the sealing resins A and B, a primer liquid can be applied to the edge surface 210 of the plate glass 200 and the holder 100 in advance. For example, silicon or the like can be used as the primer liquid. Thereby, the adhesiveness between the sealing resins A and B and the plate glass 200 and the holder 100 can be improved.

(Deformation absorption space 111)
The deformation absorbing space 111 shown in FIG. 2 is a U-shaped space surrounded by one opposing wall 110, a bottom surface 112, a fixing part 300, and a glass panel.
The deformation absorbing spaces 111 are provided on both sides of the glass panel and the fixing portion 300, and are provided on both sides of the two opposing walls 110, respectively. The deformation absorbing spaces 111 provided on both sides may be provided symmetrically or asymmetrically.
Normally, when a fire occurs, the fire occurs on one side of the partition wall, and the flame hits one side of the glass panel, causing the glass panel to be significantly thermally deformed in one direction, but it is impossible to predict which side the fire will occur on. Therefore, it is preferable that the deformation absorbing spaces 111 are provided symmetrically on both sides of the glass panel.
The thickness of the deformation absorbing space 111 (the distance obtained by subtracting the thickness of the glass panel from the distance between the inner surfaces of the pair of opposing walls) is preferably 1.6 times or more and 5.0 times or less than the thickness of the glass panel, and 3. It is more preferable to set it to 4 times or less. Further, the deformation absorbing space 111 may be provided only on one side of the glass panel, or may be provided on both sides. When the deformation absorbing space 111 is provided on both sides, the thickness of one side of the deformation absorbing space 111 is preferably 0.8 to 2.5 times, and 1.5 to 2.0 times, the thickness of the glass panel. It is preferable that

It is preferable that the deformation absorbing space 111 is provided only in the vertical column 100b and not in the horizontal column 100a. In the event of a fire, the horizontal column 100a fixes the glass panel in an unstable state due to the breakage of the fixing portion 300 of the vertical column 100b, thereby making it possible to prevent the glass panel from falling over.

(Connection part 400)
As shown in FIG. 2, the connecting portion 400 fills the gap between adjacent glass plates 200 and joins the glass plates 200 together. The connecting portion 400 has better fire resistance than the fixed portion 300.
The sealing resin B used in the connecting part 400 has excellent fire resistance, so even if the fixed part 300 breaks in the event of a fire, the connecting part 400 will not break. Therefore, since the connecting portion 400 can also prevent gas from passing through, it is possible to suppress smoke from leaking into other rooms in the event of a fire.
As the sealing resin B, it is preferable to use a transparent caulking material, and specifically, silicone resin or the like may be used. In addition, fire-resistant fillers, double-sided tapes, adhesives, etc. other than caulking materials may be used. Because the sealing resin B is transparent, or by using a thin material such as tape, it is possible to achieve excellent design without compromising the basic visual performance of a glass partition, which has good translucency. able to demonstrate.

Furthermore, when a transparent silicone resin is used as the sealing resin B of the connecting portion 400, it is preferable that the thickness and width of the plate glass in the thickness direction be the same as the thickness and width of the plate glass to be connected.

(Partition wall construction method)
A method of constructing the partition wall 10 described above will be described with reference to FIGS. 2 and 3.
The partition wall construction method in this embodiment includes a connecting step of connecting the glass plate 200 and the holder 100 with the fixing part 300, and sealing the edge surface 210 of the glass plate 200 fixed in the connecting step and the edge surface of another glass plate. and a sealing step of connecting with resin.

Each process will be explained in detail. First, the horizontal column 100a fixed to the floor 600 is fixed using an anchor bolt 610. An elastic member 220 is installed in the gap between the opposing walls 110 of the horizontal column 100a. The horizontal column 100a fixed to the ceiling is also fixed using bolts 510, and an elastic member 220 is installed between the opposing walls 110. Furthermore, the vertical columns 100b are fixed with screws 710 to two walls of the room where the partition wall is to be installed.
Next, in the connecting step, the glass plate 200 is arranged so that the bottom surface 112 and the edge surface 210 of the glass plate 200 face each other. Tape that can be peeled off cleanly after masking tape or the like is pasted on the front surface and back surface in contact with the edge surface 210 of the plate glass 200, and on the parts of the bottom surface 112 where the sealing resin is not filled. Sealing resin A is filled into the gap between the disposed bottom surface 112 and the end surface of the plate glass 200. At this time, the sealing resin A is applied slightly thinner than the thickness of the glass panel so that the sealing resin A does not protrude from the glass panel. Before the sealing resin A hardens, use two leveling spatulas to level the sealing resin A from both sides of the glass panel at the same time.

In the sealing step, the unfixed edge surface 210 of the glass panel fixed in the connection step and the edge surface of another plate glass are arranged so as to face each other. Masking tape is applied in the same way as in the connection process, and sealing resin B is filled in the gaps between the edges of the glass panels. Before the sealing resin B hardens, use two leveling spatulas to level the sealing resin B from both sides of the glass panel at the same time.
Through the steps exemplified above, the partition wall can be constructed accurately.

(Flame barrier performance test)
The flame blocking performance of the partition wall 10 obtained in this embodiment was tested. An overview of the flameproofing performance test and test results will be explained.
In this flame-retardant performance test, three sheets of glass with an opening size of 3,350 mm in width x 3,200 mm in height and 10 mm in thickness were prepared as glass panels, and 200 sheets of glass were sealed together using a silicone resin sealant (Shin-Etsu Chemical Co., Ltd.). (manufactured by KE420 model number) was used.
Further, as the vertical column 100b, one in which the distance of the deformation absorbing space 111 (the separation distance between the surface of the glass panel and the opposing wall 110) was 63 mm was used. Further, as the fixing part 300, each plate glass was fixed with a silicone resin sealant (model number KE420 manufactured by Shin-Etsu Chemical Co., Ltd.).
Further, as the horizontal column 100a, one in which the length of the opposing wall 110 (the length of protrusion from the bottom surface 112) was 22 mm was used. Further, the elastic member 220 was fixed with a silicone resin sealant (model number KE420 manufactured by Shin-Etsu Chemical Co., Ltd.).
