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] Generally, partitions used to separate indoor spaces are known to be constructed by connecting adjacent panel bodies in a series in the left-right direction. In order to provide such partitions with high fire resistance, it has been proposed to provide a heat-expandable (heat-foamable) fire-resistant material on the surface of the connecting parts between the panel bodies (see, for example, Patent Document 1). Incidentally, among partitions, there are not only those that use a thick panel body as the partition as in the conventional one mentioned above, but also those that are constructed using a thin partition such as a glass plate (see, for example, Patent Document 2).In these partitions, a glass plate is fitted between adjacent vertical frame members on the left and right.In this case, the glass plate is fitted into a groove formed in the vertical frame member.

[0004] However, the above-mentioned conventional system is weak in terms of strength because only the vertical frame material is used as the vertical support. Therefore, it has been proposed to erect the support body separately and then fit the vertical frame material onto the outside of the support body to create a vertical support with superior strength. However, when doing so, there are problems such as flames penetrating through the gap between the support body and the vertical frame material, and the invading flames reaching the groove portion for installing the glass plate provided in the vertical frame material, causing early damage to the glass plate fitting portion and compromising fire resistance. These are the problems that the present invention aims to solve. [Means for solving the problem]

The invention of claim 5 is a partition as described in any one of claims 2 to 4, characterized in that the heat-expandable fire-resistant material is provided on a surface portion that has an opposing surface among the surfaces that surround and form the space. Effect of the Invention

[0006] According to the invention of claim 1, the vertical support that constitutes the partition is provided with a support body and a vertical frame material, and the support body is Pillar body The vertical frame material is provided with a side facing surface and a side facing surface. Pillar body The frame side facing surface portion is fitted externally to the facing surface portion with a gap therebetween, and the facing surface portion is provided with a recessed groove portion into which a partition plate is fitted internally to the facing surface portion on the frame side, and a recessed groove portion extending from the leading edge of the frame side facing surface portion.

[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 constructed as described above, the vertical supports 2, 3 provided to constitute the partition 1 are constructed with a support body 5 and a vertical frame member 6, and in this case, the support body 5 is constructed with a main body side sighting surface portion 5e and a sighting surface portion 5d. On the other hand, the vertical frame member 6 is equipped with a frame member side sighting surface portion 6b and a sighting surface portion 6a which are fitted externally with a gap existing between the main body side sighting surface portion 5e and the sighting surface portion 5d, and furthermore, the frame member side sighting surface portion 6a is formed with a concave groove portion 6c into which the glass plate 4 is fitted and a frame member side bent surface portion 6d which is bent from the tip edge of the frame member side sighting surface portion 6b toward the main body side sighting surface portion 5e side, so that it has an arch shape, and a U-shaped auxiliary frame member 7 is provided to this to increase its strength.

[0024] In the partition 1 of this embodiment thus constructed, the second fireproof material 16 is provided in the space S2 that surrounds at least three surfaces, namely, the main body side sighting surface 5e, the frame material side sighting surface 6b, and the frame material side bent surface 6d. As a result, the frame material side bent surface 6d is formed by bending the tip edge of the frame material side sighting surface 6b toward the main body side sighting surface 5e, and the vertical supports 2, 3 can be constructed with excellent strength. As a result, if a flame enters through the gap between the pillar main body 5 and the vertical frame material 6, the entry path of the invading flame is closed by the second fire-resistant material 16 provided in the space S2 surrounded by at least three sides, namely, the main body side visible surface portion 5e, the frame material side visible surface portion 6b, and the frame material side curved surface portion 6d, and the flame is prevented from reaching the groove portion where the glass plate 4 is inserted, thereby providing high fire resistance. Moreover, with regard to the vertical support 3 in this embodiment, the space S2 is surrounded by four sides, namely the three sides of the main body side visible surface portion 5e, the frame side visible surface portion 6b, and the frame side curved surface portion 6d, as well as the auxiliary frame side visible surface portion 7a, thereby further improving the effect of blocking the flame intrusion path, and further improving the fire prevention performance.

[0025] Furthermore, in this case, the second fire-resistant material 16 is a heat-expandable fire-resistant material that expands in response to heat during a fire, so that it fills the space S2 surrounded by the three sides in a tightly packed (sealed) state, thereby providing a high level of blocking the entry path of flames, thereby providing even greater fire resistance and fire prevention properties.

[0026] Furthermore, when the vertical support 2 is installed adjacent to a wall surface, since there is no auxiliary frame material 7, a space S2 is formed surrounding three sides which, compared to the vertical support 3, do not have the auxiliary frame side visible surface portion 7a, and furthermore, the main body side visible surface portion 5e is configured to have the leg piece portion (rail surface portion) 14c of the wall side rail 14 attached to the wall surface W fitted onto it, and the main body side visible surface portion 5e for surrounding and forming the space S2 is configured to form the space S2 via the leg piece portion 14c. However, even in such a vertical support 3, high fire resistance can be exhibited by providing the second fire-resistant material 16 in the space S2.

[0027] 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. 18(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. As in the above-mentioned embodiment, this embodiment also has the first and second fireproof materials 15 and 16, but the second fireproof material 16 is provided on the auxiliary frame side bent surface portion 7b, and this embodiment can also achieve high fire resistance.

[0028] Furthermore, as for the auxiliary frame material 7, as in the third embodiment shown in Figure 18 (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.

[0029] Furthermore, the present invention can also be provided with a second fire-resistant material 16 as in the fourth and fifth embodiments shown in Figures 19(A) and (B). In the fourth embodiment, the second fire-resistant material 16 is provided on the frame material side bent surface portion 6d, and in the fifth embodiment, the second fire-resistant material 16 is provided on the auxiliary frame side visible surface portion 7a. Even in this way, high fire resistance is achieved by blocking the entry path of flames. [Industrial Applicability]
