Description

[Technical field]

[0001] The present invention relates to the technical field of partitions formed by fitting a thin partition plate such as a glass plate between adjacent vertical posts on the left and right. [Background technology]

[0002] Nowadays, a partition is often used to separate an indoor space into front and back sections by fitting a thin partition plate such as a glass plate between adjacent vertical posts on the left and right. One such partition is constructed by using the vertical posts as a main body that is erected between the floor and ceiling, and a vertical frame material with a groove portion formed in it for fitting the partition plate. In this case, the pillar body is made rectangular in plan view with a concave surface portion and a visible surface portion, while the vertical frame material is made U-shaped with a concave surface portion and a visible surface portion so that it fits externally between the concave surface portion and the visible surface portion of the pillar body with a gap, and a groove portion is formed in the concave surface portion for fitting a partition plate internally (see, for example, Patent Document 1). However, when glass plates are used as partition panels for partitions, general glass materials have low melting points and poor fire resistance (fire resistance), and therefore cannot be used as glass plates that require high fire resistance. On the other hand, there are glass materials with high melting points and excellent fire resistance, but such glass materials are expensive and have rarely been used as glass plates for partitions. However, today, with the improvement of glass material technology, glass plates with high melting points and excellent fire resistance can be provided at low prices, and therefore attempts are being made to provide partitions with high fire resistance using such glass plates.

[0003] [Patent Document 1] JP 2016-79744 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, because the conventional partitions using glass plates did not require consideration of high fire resistance, the vertical frames were made of aluminum, which can be easily formed into complex shapes by simple processing such as extrusion molding. However, aluminum has a melting point of approximately 660°C, which is a low melting point for metals used as building materials, and for this reason is not suitable for use as partitions in areas where high fire resistance is required, so in such cases the vertical frames are made of metal materials with high melting points such as steel (iron) and stainless steel. However, such high-melting point metal materials cannot be precisely processed into complex shapes by extrusion, as aluminum can, and so the plate material must be shaped by bending. However, this type of bending makes it virtually difficult to process complex shapes into such shapes. For this reason, when the bent vertical frame material is incorporated into the pillar body to form a vertical pillar, a gap inevitably occurs between the pillar body and the vertical frame material. In the event of a fire, smoke from the fire that penetrates between the pillar body and the vertical frame material through this gap may reach the groove portion that holds the partition plate in place, and the partition plate's holding function in the groove portion may be damaged early by the high heat, resulting in a loss of fire resistance. These are the problems that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention has been created in view of the above-mentioned circumstances and with the objective of solving these problems. The invention of claim 1 comprises vertical supports provided adjacent to each other on the left and right, and a seat installed between the vertical supports. LamellarThe vertical support comprises a support body and a vertical frame member, the support body having a visible surface portion and a visible surface portion on the body side, the vertical frame member having a frame member visible surface portion and a visible surface portion which are fitted externally with a gap between the body side visible surface portion and the visible surface portion, and a recessed groove portion into which the partition plate is fitted is formed in the frame member side visible surface portion, and an auxiliary frame member is sandwiched between the body side visible surface portion and the groove bottom surface portion of the recessed groove portion, and the auxiliary frame member is extended so that its tip edge portion extends beyond the body side visible surface portion and faces closely to or abuts against the frame member side visible surface portion. The partition plate is made of a plate material processed into a thin plate shape from a fire-resistant material, and the support pillar body, vertical frame material, and auxiliary frame material are formed by bending a fire-resistant metal material having a higher melting point than aluminum. This is a partition characterized by the above. The invention of claim 2 is a partition as described in claim 1, characterized in that the auxiliary frame material is in a flat state that extends along the visible surface portion of the main body side, reaching the visible surface portion of the frame material side, and is provided with a folded surface portion that is bent to fit along the visible surface portion of the frame material side. The invention of claim 3 is a partition according to claim 2, characterized in that the folded surface portion is folded toward the frame material side visible surface portion. The invention of claim 4 is a partition as described in claim 1, characterized in that the auxiliary frame material has a visible folded surface portion bent from the tip edge of the main body side visible surface portion along the main body side visible surface portion, and a visible folded surface portion bent from the tip edge of the visible folded surface portion to follow the frame material side visible surface portion, and the tip edge of the visible folded surface portion is closely opposed to or abuts the frame material side visible surface portion. The invention of claim 5 is a partition as described in claim 4, characterized in that the vertical frame material has a frame material side folded surface portion in which the tip edge portion of the frame material side visible surface portion is folded toward the main body side visible surface portion, and the visible folded surface portion is arranged so as to follow the frame material side folded surface portion. Effect of the Invention

[0006] By adopting the invention of claim 1, when the vertical support, which is a component part of the partition, is configured so that an auxiliary frame material is sandwiched between the support body and the vertical frame material, the tip edge of the auxiliary frame material extends beyond the main body side visible surface portion so as to face closely to or abut against the frame material side visible surface portion.As a result, flames attempting to penetrate through the gap between the support body and the vertical frame material are blocked by the part of the tip edge of the auxiliary frame material that extends beyond the main body side visible surface portion and faces closely to or abuts against the frame material side visible surface portion, thereby effectively preventing the flames from penetrating inside, thereby improving fire resistance. By adopting the invention of claim 2, the auxiliary frame material has a folded surface portion that is folded from the tip edge portion of the auxiliary frame material to fit along the visible surface portion of the frame material, thereby narrowing the flame penetration path while maintaining the left and right width, resulting in higher fire resistance. By adopting the invention as defined in claim 3, the bent surface portion provided on the auxiliary frame material is bent toward the downstream side of the flame penetration path, thereby providing a high flame penetration prevention effect and contributing to further improving fire resistance. By adopting the invention of claim 4, the auxiliary frame material is provided with a visible folded surface portion bent along the visible surface portion on the main body side, and a visible folded surface portion bent along the visible surface portion on the frame material side, and the leading edge portion of the visible folded surface portion is in close proximity to or in contact with the visible surface portion on the frame material side.As a result, in addition to the fireproof effect of claim 1 due to the leading edge portion of the visible folded surface portion being in close proximity to or in contact with the visible surface portion on the frame material side, a fireproof effect can also be achieved due to the visible folded surface portion running along the visible surface portion on the frame material side, thereby achieving higher fireproofing properties. By adopting the invention of claim 5, the anticipated curved surface portion provided on the auxiliary frame material fits along the frame material side curved surface portion provided on the vertical frame material, thereby making it possible to narrow the width of the flame penetration path, thereby making it more fire-resistant.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a partition that divides an indoor space into front and rear, and the partition 1 is composed of a vertical support 2 provided adjacent to a wall surface W of a building frame, a vertical support 3 provided independently in the indoor space, and a glass plate 4 that is a thin-plate-like partition plate that is fitted between the vertical supports 2 and 3. In this case, the glass plate 4 is made of a fire-resistant (heat-resistant, flame-resistant) glass material, which enhances the fire resistance of the partition 1; however, the partition plate used in the present invention is not limited to the glass plate 4, and various types of plate materials with excellent fire resistance, such as plate materials made of metals such as iron and iron alloys, and non-combustible materials such as gypsum, calcium silicate, and calcium carbonate, can be used as the partition plate.

[0009] Both of the vertical supports 2, 3 are configured to include a support body 5 that is erected between a ceiling surface H and a floor surface F without the ceiling rails and floor rails that are usually installed on the ceiling surface H and floor surface F, and a vertical frame material 6 that is assembled to the support body 5.First, we will explain the vertical support 3 that is erected independently in the indoor space. Each of the vertical supports 3 is formed by bending steel material and is composed of a support body 5, vertical frame materials 6 attached to both the left and right sides of the support body 5, and auxiliary frame materials 7 sandwiched between the support body 5 and the vertical frame materials 6, with the support body 5 being set to be shorter than the dimension (height dimension) between the ceiling surface portion H and the floor surface portion F.

[0010] The pillar main body 5 comprises a first pillar member 5a which is long in the front-to-rear direction and has an opening on one side in the front-to-rear direction when viewed in a plane, and a second pillar member 5b which is shaped like a square and has an opening on the opposite side to the first pillar member 5a to cover the opening of the first pillar member 5a.The two leg pieces of the second pillar member 5b are fitted into the opening side of the first pillar member 5a and the overlapping leg pieces are fixed to each other with screws 5c, thereby forming a cylindrical body which is rectangular in plan view, and is configured so that the long sides (the two leg pieces of the first pillar member 5a) form the left and right visible surfaces (hereinafter referred to as the "main body side visible surfaces") 5d, and the short sides (the straddling parts of the first and second pillar members 5a, 5b) form the front and rear visible surfaces (hereinafter referred to as the "main body side visible surfaces") 5e. In this case, in this embodiment, both upper and lower end edge portions of the leg piece portion 5h of the second support member 5b are cut out to accommodate the floor side positioning member 8 and support member 10 described later, and as a result, both upper and lower end edge portions of the support main body 5 are formed by cutting out (missing) the leg piece portion 5h of the second support member 5b, and the spanning piece portion of the first support member 5a and both leg piece portions and the spanning piece portion of the second support member 5b form the four sides of a square when viewed in plan. Incidentally, as the support body 5, a rectangular tubular body having a rectangular shape or the like may be used as it is, and if necessary, the first support member 5a alone may remain U-shaped.

[0011] On the other hand, the vertical frame material 6 is provided with a projection surface portion (hereinafter referred to as the "frame material side projection surface portion") 6a which fits externally to the main body side projection surface portion 5d and the projection surface portion 5e with a gap present, and a projection surface portion (hereinafter referred to as the "frame material side projection surface portion") 6b, and a groove portion 6c into which the glass plate 4 is fitted is formed in the frame material side projection surface portion 6a, giving it a bow shape in a planar view, and furthermore, the front and rear frame material side projection surface portions 6b are structured so that frame material side folded surface portions 6d are bent from the tip edge portions toward the inside in the front-to-rear direction. The vertical frame material 6 is fitted externally into the main body visible surface portion 5e through openings formed between the tip edges of the front and rear frame material side curved surface portions 6d on both the left and right sides of the pillar main body 5 (the sides facing the main body side visible surface portion 5d).In the present invention, the auxiliary frame material 7 is fitted between the pillar main body 5 and the vertical frame material 6 as described above, which increases the strength and improves the fire resistance of the vertical pillar 3, as will be described later. Incidentally, a notch 6g is formed at the upper edge of the vertical frame material 6 for loosely fitting a fixing piece portion 10e of a support member 10, which will be described later.

[0012] In this embodiment, the auxiliary frame material 7 is U-shaped in plan view and is configured with an auxiliary frame side projection surface portion 7a that is sandwiched between the main body side projection surface portion 5d and the groove bottom surface portion 6e of the concave groove portion 6c, and the auxiliary frame side projection surface portion 7a extends in the front-rear direction beyond the main body side sight surface portion 5e (beyond the front and rear end edges of the main body side sight surface portion 5d) and is formed in a flat plate shape (flush surface) so that the extended front and rear end edges are closely opposed to or abut against the frame material side sight surface portion 6b.The auxiliary frame side bent surface portion 7b is formed by bending the front-rear end edge of the auxiliary frame side projection surface portion 7a toward the outside in the left-right direction while following the frame material side sight surface portion 6b. Similarly to the vertical frame member 6, the auxiliary frame member 7 is also formed with a notch 7c into which the fixing piece portion 10e of the support member 10 is loosely fitted.

[0013] The vertical support 3, which is composed of the support main body 5, a pair of left and right vertical frame members 6, and auxiliary frame member 7, is erected between the floor surface F and the ceiling surface H in an independent state without a ceiling rail, and therefore uses positioning members 8, 9 provided on the floor surface F and the ceiling surface H, respectively, and a support member 10 used to incorporate the support main body 5 into the ceiling surface side positioning member 9, which will be explained next. First, each positioning member 8, 9 is U-shaped, and when positioned at the upright position of the vertical support 3 on the floor surface F and ceiling surface H, the spanning portion abuts and is fixed via screws 8a, 9a.

[0014] In contrast, the support member 10 is configured with a main body portion 10a that is U-shaped in a plan view, and a blocking portion 10b that is inverted U-shaped in a plan view and is integrally provided in a state of being fitted into the upper half of the main body portion 10a and blocks the upper half of the opening of the main body portion 10a, and is set to be fitted inside so as to be freely adjusted in the vertical position from the upper end edge of the support body 5. The upper end edge of the spanning piece portion 10c of the main body portion 10a is set to be located higher than the upper end edges of the front and rear leg pieces 10d, and a fixing piece portion 10e is bent outward in the left-right direction from the upper end edge of the spanning piece portion 10c. On the other hand, the blocking portion 10b is configured to configure the upper half of the support member 10 into a square tube shape in a plan view by the spanning portion 10f blocking the opening side of the main body portion 10a, and furthermore, is incorporated into the upper half portion of the main body portion 10a with both leg piece portions 10g fitted into both leg piece portions 10d of the main body portion 10a. However, the upper edge portion 10h of the incorporated blocking portion 10b is provided so as to be flush with the main body portion leg piece portion 10d. By being configured in this manner, the support member 10 is set so that the upper edge portion 10h and the fixing piece portion 10e are flush with each other. Incidentally, when the support member 10 is fitted into the upper edge portion of the pillar body 5, the fixing piece portion 10e is set to descend under its own weight until it abuts against the upper edge portion of the pillar body 5.

[0015] With each component configured in this manner, to erect the vertical support 3 independently between the floor surface F and ceiling surface H of the indoor space (without a ceiling rail or floor rail), first the positioning members 8, 9 on the floor surface and ceiling surface are positioned on the floor surface F and ceiling surface H, respectively, and then attached and fixed to the floor surface F and ceiling surface H using screws 8a and 9a. Thereafter, the pillar body 5 with the support member 10 fitted inside from the upper edge is raised, and the lower edge of the pillar body 5 is externally fitted into the floor side positioning member 8 and abutted against the floor surface F. In this case, the pillar body 5 is shorter than the dimension between the ceiling surface portion H and the floor surface portion F, and the support member 10 has descended under its own weight so that the fixed piece portion 10e which becomes the upper edge is located at a low position abutting against the main body side visible surface portion 5d, so that there is no hindrance to the erection and assembly of the pillar body 5.

[0016] After the lower edge of the pillar main body 5 is assembled into the floor-side positioning member 8 in this manner, the support member 10 fitted inside the upper edge of the pillar main body 5 is moved upward and the upper edge of the support member 10 is assembled and fitted outside into the ceiling-side positioning member 9, thereby positioning the upper edge of the pillar main body 5 relative to the ceiling surface H, and in this state, the fixing piece portion 10h is fixed to the ceiling surface H via a screw 10i. In this way, the pillar body 5 is erected in a self-supporting state with both upper and lower end edges positioned via the ceiling-side and floor-side positioning members 9, 8. Incidentally, the lower end edge of the pillar body 5 erected in this way is fixed to the floor-side positioning member 8 via a screw 5f.

[0017] After the pillar main body 5 has been set up in the position described above, the vertical pillar 3 is formed by assembling the auxiliary frame material 7 and the vertical frame material 6 to both the left and right sides of the pillar main body 5. To do this, the auxiliary frame material 7 is assembled so that its projected surface portion 7a abuts the main body side projected surface portion 5d of the pillar main body 5 with its lower edge abutting the floor surface F, and the vertical frame material 6 is assembled so that the groove bottom portion 6e of the concave groove portion 6c abuts the projected surface portion 7a of the auxiliary frame material 7 with its lower edge abutting the floor surface F. In this assembled state, the auxiliary frame material 7 and the vertical frame material 6 are fixed to the pillar main body 5 via screws 5g screwed into the groove bottom portion 6e of the concave groove portion at an appropriate vertical interval, thereby assembling the vertical pillar 3 in a position relative to the floor surface F and ceiling surface H.

[0018] Next, the assembly structure of the vertical support 2 that is assembled adjacent to the wall surface W will be described. In this case, the vertical support 2 does not have the auxiliary frame material 7 provided on the vertical support 3. In this case, the straddling piece 14a of the wall rail 14, which is shaped like a square in a plan view, is attached to the wall surface W via the screw 14b, and the support body 5 is positioned and attached between the floor surface F and the ceiling surface H via the floor surface side positioning member 8, the ceiling side positioning member 9, and the support member 10, as in the case of the vertical support 3, in a state where it is fitted into the leg piece portion 14c of the attached wall rail 14. The vertical support 2 is set to be assembled by similarly assembling the vertical frame material 6 to the projection surface portion 5d on the opposite side of the wall surface W of the attached support body 5. Incidentally, the leg piece 14c of the wall rail 14 is set to extend further inward in the left-right direction than the pillar main body 5. This is to absorb any assembly errors that may occur when assembling the partition 1 so that the pillar main body 5 always fits within the wall rail 14, as well as to make it difficult for flames to penetrate into the vertical pillar 2.

[0019] Then, with the left and right edge portions of the upper and lower horizontal frame members 11, 12 butting against the upper and lower edge portions of the frame-side visible surface portion 6a of the vertical frame member 6 of the positioned and assembled vertical posts 2, 3, the upper and lower horizontal frame members 11, 12 are attached to the vertical frame member 6 via L-shaped connecting metal fittings 13, and the glass plate 4 is fitted into the concave groove portion 6c provided in the vertical frame member 6 and the concave groove portions 11a, 12a provided in the upper and lower horizontal frame members 11, 12 to form the partition 1. Note that 13a is a screw for fixing the connecting metal fittings 13 to the groove bottoms 6c, 11a, 12a of the vertical frame member 6 and the upper and lower horizontal frame members 11, 12. The horizontal frame members 11, 12 are fixed to the ceiling surface H and floor surface L by screwing screws 11b, 12b into the groove bottoms 11a, 12a at an appropriate interval.

[0020] The partition 1 is thus formed by fitting a glass plate 4 between the vertical supports 2, 3 which are erected with a gap on the left and right sides. Furthermore, the vertical supports 2, 3 are provided with first and second fire-resistant materials (flame-blocking materials) 15, 16 which have fire-resistant and thermal expansion properties and which expand in volume when exposed to heat during a fire, etc., thereby blocking flames. The first fire-resistant material 15 is provided on the groove side portion 6f of the groove portion 6c at the corner portion where the horizontal frame members 11, 12 of the vertical frame member 6 into which the glass plate 4 is inserted abut.In order to prevent flames (including smoke (fire smoke)) from passing through the gap between the vertical frame member 6 and the horizontal frame members 11, 12 at the portion where they abut, it is sufficient for the first fire-resistant material 15 to extend slightly beyond the portion of the space portion S1 formed by the groove portion 6c where the horizontal frame members 11, 12 are provided, and therefore the first fire-resistant material 15 is set to be short from the upper and lower edge portions of the groove side portion 6f to the portion where the horizontal frame members 11, 12 abut in the vertical direction.

[0021] In contrast, the second fire-resistant material 16 is intended to prevent flames on the side where a fire has occurred from penetrating into the vertical frame material 6 between the tip edge of the frame material side bent surface portion 6d of the vertical frame material 6 and the main body side visible surface portion 5e of the pillar main body 5, and is therefore provided over approximately the entire length of the vertical pillars 2, 3. In this case, for the vertical support 3 on which the auxiliary frame member 7 is provided, the second fireproof material 16 is provided in the space S2 surrounded on all four sides by the frame member side visible surface portion 6b of the vertical frame member 6, the frame member side bent surface portion 6d, the main body side visible surface portion 5e of the support main body 5, and the auxiliary frame side visible surface portion 7a of the auxiliary frame member 7, and the second fireproof material 16 is provided on the frame member side visible surface portion 6b before expansion in the space S2. When the second fireproof material 16 expands due to heat during a fire, the second fireproof material 16 expands so as to abut against the opposing main body side visible surface portion 5e, filling the space S2, thereby preventing the intrusion of flames into the vertical frame member 6.

[0022] On the other hand, for the vertical support 2 without the auxiliary frame member 7, the second fireproof material 16 is provided in the space S2 surrounded on three sides by the main body side sighting surface 5e of the support main body 5, the frame side sighting surface 6b of the vertical frame member 6, and the frame side bent surface 6d, and for the main body side sighting surface 5e of the support main body 5, the space S2 is formed with the leg piece portion 14c of the wall rail 14 interposed therebetween. The second fireproof material 16 is provided on the frame side sighting surface 6b, and when the second fireproof material 16 expands due to heat during a fire, it expands toward the opposing main body side sighting surface 5e side so as to abut against the leg piece portion 14c of the wall rail 14 and fill the space S2, thereby preventing the intrusion of fire smoke into the vertical frame member 6.

[0023] In the present embodiment configured as described above, the partition 1 comprises vertical pillars 2, 3 arranged adjacent to each other on the left and right and a thin glass panel 4 inserted between the vertical pillars 2, 3, thereby dividing the interior space into front and back. In this case, the vertical pillars 2, 3 are configured to comprise a pillar body 5 and a vertical frame material 6. The pillar main body 5 is configured with a main body side visible surface portion 5e and a main body side visible surface portion 5d, while the vertical frame material 6 is configured with a frame material side visible surface portion 6b and a visible surface portion 6a which are externally fitted with a gap between the main body side visible surface portion 5e and the visible surface portion 5d, and the frame material side visible surface portion 6a is bow-shaped with a groove portion 6c into which the glass plate 4 is fitted, and of the vertical pillars 2, 3, the vertical pillar 3 which is erected independently in the indoor space has an auxiliary frame material 7 sandwiched between the main body side visible surface portion 5d and the groove bottom surface portion 6e of the groove portion 6c. Furthermore, this auxiliary frame material 7 has a tip edge that extends beyond the main body side visible surface portion 5e so that it closely faces or abuts the frame material side visible surface portion 6b, so that the gap between the pillar main body 5 and the vertical frame material 3 is almost completely closed.As a result, flames that occur in the event of a fire are prevented from entering through the gap between the pillar main body 5 and the vertical frame material 3, effectively preventing the entry of flames and improving fire resistance.

[0024] Moreover, the auxiliary frame material 7 in this embodiment is configured so that it is in a flat state along the main body side visible surface portion 5d, extending to the frame material side visible surface portion 6b, and is provided with an auxiliary frame side folded surface portion 7b that is folded to fit along the frame material side visible surface portion 6b.Therefore, the flame penetration path between the tip edge of the auxiliary frame material 7 and the frame material side visible surface portion 6b is narrowed by maintaining the left and right width due to the provision of the auxiliary frame side folded surface portion 7b, which makes it possible to better prevent flames from penetrating, and results in high fire resistance. Furthermore, in this case, the auxiliary frame side folded surface portion 7b is folded toward the frame material side projecting surface portion 6a, so that it is folded downstream of the flame intrusion path, which contributes to flame extinguishing and provides a high flame intrusion prevention effect, thereby contributing to further improving fire resistance.

[0025] Of course, the present invention is not limited to the above-mentioned embodiment, and when the auxiliary frame member 7 is provided with the auxiliary frame side bent surface portion 7b, the auxiliary frame side bent surface portion 7b can be bent toward the frame side bent surface portion 6d, as shown in the second embodiment in Fig. 17(A), in the opposite manner to the first embodiment, and the bent tip edge portion can be extended to the vicinity of the corner portion between the frame side visible surface portion 6b and the frame side bent surface portion 6d, and high fire resistance can be achieved by configuring in this manner. And, like the above-mentioned embodiment, this also has the first and second fireproof materials 15, 16, but the second fireproof material 16 is provided on the auxiliary frame side bent surface portion 7b.

[0026] Furthermore, as for the auxiliary frame material 7, as in the third embodiment shown in Figure 17 (B), the auxiliary frame side visible surface portion 7a is equipped with a visible folded surface portion 7d folded from the tip edge portion of the main body side visible surface portion 5d along the main body side visible surface portion 5e, and a visible folded surface portion 7e folded from the tip edge of the visible folded surface portion 7d toward the frame material side visible surface portion 6b, and the tip edge of the visible folded surface portion 7e is configured to face closely to or abut against the frame material side visible surface portion.By configuring it in this manner, in addition to the fireproofing effect due to the tip edge of the visible folded surface portion 7e of the auxiliary member 7 being in close proximity to or abutting the frame material side visible surface portion 6b, a fireproofing effect can be achieved by narrowing the entry path of flames by the visible folded surface portion 7d running along the main body side visible surface portion 5e, resulting in higher fireproofing. This also has first and second fire-resistant materials 15, 16, but the second fire-resistant material 16 is provided on the front bent surface portion 7d. Moreover, in this case, the anticipated curved surface portion 7e of the auxiliary frame material is arranged to fit along the frame material side curved surface portion 6d provided on the vertical frame material 6, so that the fire prevention effect can also be achieved here by narrowing the flame penetration path, resulting in higher fire resistance. In this case, the second fireproof material 16 may be provided on the visible surface portion 6b of the frame material as in the above embodiment, and it is of course possible to provide it on both.
