Description

[Technical Field]

[0001] The present invention relates to the technical field of a board material mounting structure and a board material mounting method for a partition panel provided to divide an interior space. [Background technology]

[0002] Generally, partition panels are known that are constructed by placing a panel body for dividing the interior space of a building or other structure into front and back sections between upper and lower rail materials installed on the ceiling and floor, respectively. However, among the panel bodies that make up such partition panels, there is one proposed in which a board material made of an inorganic material such as gypsum, calcium silicate, calcium carbonate, etc. is placed in an overlapping (laminated, superimposed) state on one side of the panel body in the front-to-rear direction relative to the rail material, thereby sealing the gap between the opposing rail material and the panel body, thereby improving sound insulation, fire resistance, etc. (See, for example, Patent Document 1). In this structure for attaching a board material to a rail material, a square-shaped attachment member with openings on the outer side in the vertical direction is placed on the rail material in a fitted state, and the outer end of the top and bottom direction of the surface panel that surrounds and covers the board material is fitted into a fitting groove provided on one of the front and rear sides of the attachment member, and the attachment member and board material are attached and fixed to the rail material by a long screw screwed into the other front or rear side of the attachment member.

The invention of claim 6 is a board material mounting structure for a partition panel described in claim 5, characterized in that the groove for the horizontal airtight material is bent so that the vertical inner portion of the second inner piece bulges toward the panel body, thereby forming a deep groove with the opening side end of the vertical outer groove side piece biased toward the panel body. The invention of claim 7 is a method for attaching a board material to at least one of the upper and lower rail members in a manner that overlaps the panel body in the front-to-rear direction of a partition panel in which a panel body for dividing an interior space into front and rear sections is arranged between upper and lower rail members provided on the ceiling and floor surfaces, and whose upper and lower end edges are located between the rail members, the method comprising the following steps: a first screw fixing step of screwing an auxiliary piece member, which has a second inner piece member formed in the inward direction of the vertical direction, to an attachment piece member, which has a first inner piece member formed in the outward direction of the vertical direction, so that the first and second inner pieces are flush with each other; a board material arranging step of arranging the board material on the flush first and second inner pieces so that the side of the panel body is covered; a board material storing step of connecting an outer piece member to the first inner piece member so as to cover the side of the opposite panel body of the arranged board material, thereby forming a tubular board material mounting portion, and surrounding and storing the board material in the board material mounting portion; and a second screw fixing step of screwing the attachment piece member to the rail member. The invention of claim 8 is a method for attaching board material to a partition panel described in claim 7, characterized in that the first screw fixing process, the board material arrangement process, and the board material storage process are performed in a factory, and the second screw fixing process is performed on site. [Effects of the Invention]

[0006] By adopting the invention of claim 1, the board material mounting portion for mounting the board material to at least one of the upper and lower rail materials is formed with a first inner piece portion formed on a mounting piece member fixed with screws to the rail material, a second inner piece portion formed on an auxiliary piece member fixed with screws to the mounting piece member, and an outer piece member connected to at least one of the first and second inner piece portions, and the board material is enclosed and stored in the board material mounting portion.As a result, the structure of the board material mounting portion for enclosing and storing the board material is simplified, the number of parts is reduced, and the assembly work can be made more efficient. By adopting the invention of claim 2, the board material can be attached and fixed to the board material attachment portion by adhesion or bonding, which makes it easy. By adopting the invention of claim 3, the connection of the outer piece member to the first inner piece portion is made by connecting the outer piece member to the bent piece portion formed as the first inner piece portion by bending it outward in the fore-and-aft direction, thereby simplifying the connection structure of the outer piece member to the first inner piece portion and improving workability. By adopting the invention of claim 4, the connection between the bent piece portion and the outer piece member is achieved by fitting the locking protrusion formed on the tip edge of the outer piece member into the locking groove formed on the tip edge of the bent piece portion, thereby making it possible to easily connect the bent piece portion and the outer piece member. By adopting the invention of claim 5, when a horizontal airtight material is provided at the vertical inner end of the board material mounting portion to abut the panel body, the groove for the horizontal airtight material for accommodating the horizontal airtight material can be composed of a vertical outer groove side piece and a groove bottom piece that are bent and formed at the vertical inner portion of the second inner piece portion, and a vertical inner groove side piece that is bent and formed at the vertical inner portion of the outer piece member, making it easy to form a groove for the horizontal airtight material in the board material mounting portion. By adopting the invention of claim 6, the groove for the horizontally-oriented airtight material is bent so that the vertically inner portion of the second inner piece bulges toward the panel body, and as a result, the opening side end of the vertically outer groove side piece of the groove for the horizontally-oriented airtight material can be made deep and biased toward the panel body, which results in the horizontally-oriented airtight material being installed in a deep groove, thereby allowing for stable installation of the horizontally-oriented airtight material. By adopting the invention of claim 7, a method for attaching a board material to one side of at least one of the upper and lower rail materials in the front-to-rear direction, overlapping the panel body, includes the steps of: fixing an auxiliary piece member having a second inner piece portion to an attachment piece member having a first inner piece portion; arranging the board material on the first and second inner piece portions; connecting an outer piece member to the first inner piece portion so as to cover the side of the arranged board material opposite the panel body, thereby forming a board material attachment section in which the board material is enclosed and stored; and fixing the attachment piece member to the rail material with screws.As a result, the work of attaching the board material to the rail material is simplified and the efficiency of the board material attachment work is improved. By adopting the invention of claim 8, the board material is transported to the site surrounded and stored in the board material mounting section, and at the work site, it is assembled into the partition panel simply by performing the second screw fixing process, thereby simplifying on-site work and improving workability.

DETAILED DESCRIPTION OF THE INVENTION

[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 panel that separates the interior space of a building into a front-to-back space, and the partition panel 1 is provided to separate the interior space into a space S that is constantly used by people, such as an office space or a living space, and a storage space T that has a narrow depth and is used to store various devices such as machinery and equipment, machinery devices, and air conditioners. The partition panel 1 of this embodiment is made up of a total of four panel bodies P1 to P4 arranged in a series adjacent to each other on the left and right. The first and fourth panel bodies P1, P4 on the left and right outer sides are configured as swing doors, with the outer left-right end edges of the door tails pivoted to the left and right vertical frames (vertical supports) 2, which are the main body side members, via hinges 3 so that they can swing freely back and forth in the forward direction and open to the front use space S.The second and third panel bodies P2, P3 on the left and right inner sides are of the sliding type, which are opened and closed left and right by running rollers 7 rolling on guide rails 6 on the floor surface F side, with an anti-sway body 5 fitted into an anti-sway rail 4 on the ceiling surface H side so that it can move freely left and right in order to prevent vibration (falling) in the forward and backward direction.All of these are conventional in that they are of the sliding type. In the following explanation, when the first to fourth panel bodies P1 to P4 are collectively described, they will be referred to as "panel body P", and when the individual panel bodies are described separately, they will be referred to as first to fourth panel bodies P1 to P4. In addition, the panel body P in this embodiment is a component of the partition panel 1 used to divide the interior space into a use space S and a storage space T from the front and back as described above, and therefore, for convenience, the use space S side is defined as the front side (front side, surface side) and the storage space T side is defined as the rear side (back side, back surface side) using the panel body P as the reference, and the left and right directions are defined in accordance with the description in the drawings, where the view from the use space S side is the front view, but it goes without saying that the present invention is not limited to these orientations.

[0009] The panel body P basically adopts a general-purpose structure using upper and lower horizontal frame members 8, 9, left and right vertical frame members 10, 11, front and rear panel members (front and rear panel members) 1a, 1b, and filler material 1c contained within and surrounding these. For the second and third panel bodies P2, P3, a vibration prevention body 5 is provided on the upper horizontal frame member 8, and a running roller 7 is provided on the lower horizontal frame member 9. Furthermore, for the left and right vertical frame members 10, 11 of the first and fourth panel bodies P1, P4, the one on the outside in the left-right direction where the hinge 3 is provided is defined for convenience as the trailing edge vertical frame member 10, and the one on the inside in the left-right direction as the leading edge vertical frame member 11. For the second and third panel bodies P2, P3, the one on the outside in the left-right direction adjacent to the first and fourth panel bodies P1, P4 is defined for convenience as the trailing edge vertical frame member 10, and the one on the inside in the left-right direction where the second and third panel bodies P2, P3 join together is defined for convenience as the leading edge vertical frame member 11. The panel body P constructed in this manner is arranged with an upper rail material 12 provided on the ceiling surface H and a lower rail material 13 provided on the floor surface F, with an upper and lower gap (gap) between them.

[0010] The upper and lower rail members 12, 13 are made of gypsum to close the gap between the upper and lower rail members 12, 13 and the panel body P on the storage space T side, thereby improving sound insulation, fire resistance, and other performance features, and upper and lower board members 14, which are long in the left-right direction, are attached via board attachment parts 15. Next, we will explain the structure for attaching the lower board member 14 to the lower rail member 13. Although the upper board member 14 differs slightly from the lower board member 14 in terms of dimensions and the fact that it is configured upside down, it uses the same attachment structure as the lower board member 14, so details will be omitted.

[0011] The lower rail material 13 is square-shaped with an opening at the top, which is inward in the vertical direction, and the bottom piece 13a is attached and fixed to the floor surface F via screws 13b.A board material attachment portion 15 for attaching a board material 14 is arranged on the leg piece 13c on the rear side in the front-to-rear direction, which is on the storage space T side of the lower rail material 13. The board material mounting portion 15 is configured with an attachment piece member 15a whose outer end in the vertical direction is open so as to fit externally onto both leg piece portions 13c of the lower rail material 13, and the attachment piece member 15a is U-shaped with front and rear leg piece portions 15aa, 15ab and a bottom piece portion (top piece portion) 15ac, and of the front and rear leg piece portions 15aa, 15ab extending outward in the vertical direction, the front leg piece portion 15aa serves as a fixing piece for fixing the attachment piece member 15a to the front leg piece portion 13c in the vertical direction of the lower rail material 13 via a screw 15ad, while the rear leg piece portion 15ab constitutes the first inner piece portion 15ab which is the outer half in the vertical direction of the front piece portion (front-to-back inner piece portion) of the board material mounting portion 15.

[0012] On the other hand, the vertical inner half of the front-to-back inner piece that constitutes the board material mounting portion 15 is formed as an auxiliary piece member 15b, which is formed in an L-shape with a horizontal piece portion 15ba fixed to the bottom piece portion 15ac of the mounting piece member 15a via a screw 15bc, and a vertical piece portion 15bb extending inward in the vertical direction from the rear end edge of the horizontal piece portion 15ba. By attaching and fixing the horizontal piece portion 15ba of the auxiliary piece member 15b to the bottom piece portion 15ac of the mounting piece member 15a via a screw 15bc, the vertical piece portion 15bb becomes flush with the first inner piece portion 15ab of the mounting piece member 15a, and thereby the vertical piece portion 15bb forms the second inner piece portion 15bb, which is the vertical inner half of the front piece portion of the board material mounting portion 15. Then, by gluing (or adhesively attaching) the panel body side surface 14a, which is on one side of the board material 14 in the front-to-rear direction (the side of the use space S, the front side), to the first and second inner piece portions 15ab and 15bb, which are now flush with each other, the board material 14 is attached in a state where the panel body side surface 14a is covered by the first and second inner piece portions 15ab and 15bb.

[0013] The side 14b of the attached board material 14 opposite the panel body (rear side in the fore-and-aft direction) is covered with an outer piece member 15c. In this embodiment, the outer piece member 15c is described as being connected to the first inner piece portion 15ab, but it may also be connected to the second inner piece portion 15bb. In this embodiment, the first inner piece 15ab has a bent piece 15ae formed at the outer edge in the vertical direction, which is bent toward the rear side (toward the storage space T), and a locking groove 15af is formed at the tip edge of the bent piece 15ae. Meanwhile, a locking protrusion 15ca is formed on the vertical outer end of the outer piece member 15c in correspondence with the locking recessed groove 15af. Then, with the board material 14 adhered (fixed) to the first and second inner piece portions 15ab, 15bb, and with adhesive (or double-sided adhesive tape) applied (or stuck) to the opposite-panel-body side surface 14b of the board material 14, the locking protrusion 15ca is fitted into the locking recessed groove 15af at the corner where the leading edge of the folded piece portion 15ae and the vertical outer end of the outer piece member 15c butt against each other at a right angle, thereby connecting the folded piece portion 15ae (first inner piece portion 15ab) and the outer piece member 15c and bonding the board material 14 to the outer piece member 15c.

[0014] By configuring the board material 14 in this manner, both the front and rear sides are surrounded and contained within the board material mounting portion 15, which is formed in a cylindrical shape by the first and second inner piece portions 15ab, 15bb and the outer piece member 15c, and the board material 14 can be attached to the lower rail material 13 by attaching and fixing the front leg piece portion 15aa of the mounting piece member 15a in this configuration to the front leg piece portion 13c of the lower rail material 13 via the screw 15ad. Incidentally, in this embodiment, the board material 14 is attached using an adhesive (adhesive), but this is not limitative, and it may be configured to be fixed to the first inner piece portion 15ab with screws, for example.

[0015] In this way, the board material 14 is attached to the lower rail material 13. The method for this is as follows: a first screw fixing step of fixing a side piece portion 15ba of an auxiliary piece member 15b, which has a second inner piece portion 15bb formed inward in the vertical direction, to a bottom piece portion 15ac of an attachment piece member 15a, which has a first inner piece portion 15ab formed extending outward in the vertical direction, with a screw such that the first and second inner piece portions 15ab, 15bb are flush with each other; a board material disposing step of disposing the board material 14 in a state in which the panel body side surface 14a is covered on the first and second inner piece portions 15ab, 15bb that are flush with each other; a board material storing step of connecting the outer piece member 15c to the first inner piece portion 15ab to form a cylindrical board material mounting portion 15 so as to cover the opposite panel body side surface 14b of the arranged board material 14, and surrounding and storing the board material 14 in the board material mounting portion 15; a second screw fixing step of fixing the front leg piece portion 15aa of the attachment piece member 15a to the lower rail material 13 via a screw 15ad; Each of the above steps will be carried out, but the first screw fixing step, board material arrangement step, and board material storage step will be carried out in the factory, and once these steps have been carried out, the board material stored in the board material mounting section will be transported to the site, and the second screw fixing step will be carried out on site. By configuring this to be able to simplify the steps at the site and contribute to improving workability, when all of these steps are to be carried out on site, it is preferable that the second screw fixing step be the last step from the standpoint of workability, but it may also be the first step to be carried out, or a step carried out in the middle, and these steps can be selected as appropriate by the worker on site.

[0016] Furthermore, at the inner end of the board material mounting portion 15 configured in this manner, a mounting groove 18 for a horizontal airtight material is formed for mounting a horizontal airtight material 17 that abuts against the rear side of the outer end edge of the panel body P in the vertical direction to provide airtightness. The horizontal airtight material 17 is configured to include a main body portion 17a that is fitted into the mounting groove 18 for the horizontal airtight material, and a fin-shaped abutment portion 17b that bulges in an arc from the inner edge portion of the main body portion 17a in the vertical direction so as to abut against the panel body P in an elastically deformed state and thereby provide airtightness.The horizontal airtight material groove 18 is configured in the shape of a groove with an opening on the panel body P side, consisting of an outer vertical groove side piece portion 15bd and a groove bottom piece portion 15be that are formed by bending the inner vertical portion of the second inner piece portion 15bb into an L shape, and an inner vertical groove side piece portion 15cb that is formed by bending the inner vertical portion of the outer piece member 15c toward the panel body P side.

[0017] In this case, the second inner piece 15bb is bent so that the vertical inner portion is biased (bulged) toward the panel body P, whereby the mounting groove 18 for the lateral airtight material has a deep groove shape in which the opening end of the vertical outer groove side piece 15bd is biased toward the panel body P together with the vertical inner groove side piece 15cb. With this configuration, the lateral airtight material 17 is configured so that the main body 17a can be deeply fitted into the lateral airtight material recessed groove 18 for stable mounting. The airtight material 17 used in this case has multiple peelable adjustment pieces 17c attached in a stacked manner to the groove bottom side of the main body 17a, and these adjustment pieces 17c can be adjusted so that the abutment state of the abutment part 17a against the panel body P is appropriate, allowing the abutment part 17a to abut against the panel body P reliably.

[0018] The mounting configuration of the board material 14 and the mounting configuration of the horizontal airtight material 17 are similar not only on the lower rail material 13 side but also on the upper rail material 12 side as described above, and details thereof will be omitted by referencing the above explanation, but on the lower rail material 13 side, before the lower mounting piece member 15a is attached to the lower rail material 13 via the screw 15ad, the vertical height of the mounting piece member 15a is adjusted by the height adjustment member 16 provided on the lower rail material 13, and further the guide rail 6 is provided on the horizontal piece portion 15ba of the auxiliary piece member 15b. In contrast to this, the upper mounting piece member 15a attached to the upper rail material 12 side via the screw 15ad is configured so that the vibration stopper 4 is attached and fixed to the bottom piece portion 15ac of the mounting piece member 15a together with the horizontal piece portion 15ba of the auxiliary piece member 15c via the screw 15bc, and in these respects the upper and lower mounting piece members 15a differ.

[0019] In addition, for the left and right vertical frames 2, vertically oriented board material 19 is attached via board material attachment portions 20, but in this embodiment, the body side wing piece portion 3a of the hinge 3 is attached to the left and right inner piece portion 2a of the left and right vertical support pillars 2, and the panel body side wing piece portion 3b is attached to the door tail side vertical frame material 10 of the first panel body P1, and an L-shaped mounting bracket 2b is fixed with a screw to the left and right inner piece portion 2a of the left and right vertical support pillars 2, and an integrated inner mounting piece member 20a is attached via a screw 20b.This point differs from the case where the first and second inner piece portions 15ab, 15bb are used as separate members to cover the panel body side surface 14a of the horizontally oriented board material 14 described above, but the configuration is the same, and detailed explanation thereof will be omitted.

[0020] Furthermore, the board material mounting portion 20 for mounting the vertical board material 19 configured in this manner has a mounting groove 22 for the vertical airtight material for mounting the vertical airtight material 21, but the mounting groove 22 for the vertical airtight material is also formed in a configuration similar to that of the mounting groove 18 for the horizontal airtight material, and details thereof will be omitted. The vertically oriented airtight material 21 is attached by fitting the main body 21a into the mounting groove 22 for the vertically oriented airtight material, and the abutment portions 21b protruding from the main body 21a abut against the rear surface of the panel body P in a state of elastic deformation to provide airtightness, and the abutment portions 21b have a semicircular arc shape extending from both the left and right end edges of the main body 21a. Furthermore, the vertically oriented airtight material 21 is also provided with a plurality of removable adjustment pieces 21c to adjust the insertion depth of the main body 21a into the mounting groove 22 for the vertically oriented airtight material.

[0021] Next, the structure of the joining portion between the first panel body P1 and the second panel body P2, the joining portion between the second panel body P2 and the third panel body P3, and the joining portion between the third panel body P3 and the fourth panel body P4 will be explained. However, the structure of the joining portion between the second panel body P2 and the third panel body P3, and the joining portion between the third panel body P3 and the fourth panel body P4 is different from the structure of the joining portion between the first panel body P1 and the second panel body P2 in that it is the same as or is symmetrical to the structure of the joining portion between the first panel body P1 and the second panel body P2. Therefore, only the structure of the joining portion between the first panel body P1 and the second panel body P2 will be explained, and detailed explanations of the structure of the joining portion between the second panel body P2 and the third panel body P3, and the joining portion between the third panel body P3 and the fourth panel body P4 will be omitted. A square cylindrical joint member 23 is arranged opposite the door-end side vertical frame member 10 of the second panel body P2, with a gap U in the left-right direction relative to the door-front side vertical frame member 11 of the first panel body P1.The joint member 23 has a concave groove-shaped airtight material groove 23b for the joint member, which opens on the side of the adjacent first panel body P1, formed in the corner portion on the storage space T side of the left-right end surface portion 23a facing the door-end side vertical frame member 11 of the first panel body P1.

[0022] The main body 24a of the airtight material 24 for the joint is fitted into the airtight material groove 23b for the joint, and the abutment portion 24b extending from the main body 24a is curved so as to bulge from the front corner of the main body 24a towards the first panel body P1, and is formed in a fin-like shape extending towards the rear, so that it elastically deforms and abuts against the front end face portion 11a in the direction of movement of the flat front end face portion 11a of the front end vertical frame member 11 of the first panel body P1 as it moves from front to rear to close. Furthermore, the abutment portion 24b abutting against the door front end surface portion 11a is configured so that it can be seen from the gap U between the joint portions on the storage space T side.

[0023] By configuring it in this manner, the airtight material groove 23b for the joint portion does not protrude in the front-to-back direction relative to the second panel body P2, that is, it is arranged in a state that fits within the thickness dimension of the front-to-back thickness of the second panel body P.As a result, the above-mentioned upper and lower horizontal airtight materials 17 are configured to be continuous in the left-to-right direction even at the joint portion of the first and second panel bodies P1 and P2 without being obstructed by the airtight material groove 23b for the joint portion. Incidentally, the airtight material 24 for the joint also has a main body 24a to which multiple removable adjustment pieces 24c are attached, and is configured so that the contact state of the contact portion 24b can be adjusted. In this embodiment, the joint airtight material 24 and the horizontal airtight material 17 have in common the fact that they have fin-shaped abutment portions 24b, 17b.

[0024] In this way, the upper and lower horizontal airtight materials 17 are arranged in a continuous state on the left and right without being obstructed by the airtight material groove 23b for the joint part, so that the upper and lower horizontal airtight materials 17 can be attached at the same position in the front-to-back direction as the left and right vertical airtight materials 21 and abut against the panel body P to exhibit airtightness, thereby simplifying the structure. In this case, the horizontal airtight material 17 and the vertical airtight material 21 butt against each other at the four corners, but as mentioned above, the abutting portion 17b of the horizontal airtight material 17 is fin-shaped and configured as a cantilever extending from one edge of the main body 17a, while the abutting portion 21b of the vertical airtight material 21 is configured as a double-supported protrusion from the main body 21a, so they have different shapes.If such a configuration were to be made, for example, such that the vertical airtight material 21 extends to the corner end and the horizontal airtight material 17 abuts against the vertical airtight material 21, gaps would be formed due to the different shapes of the abutting portions 17b and 21b, which would cause a loss of airtightness. Therefore, in this embodiment, the horizontal airtight material 17 is cut out while leaving the abutment portion 17b and the opening side piece 17aa of the main body portion 17a, and the V-shaped piece formed by the remaining abutment portion 17b and opening side piece 17aa is overlapped with the abutment portion 21b of the vertical airtight material 21, and the overlapping abutment portion 17b and opening side piece 17aa are both elastically deformed by the closing panel body P, thereby ensuring airtightness. In this case, both the upper and lower end edges of the vertical airtight material 21, the main body portion 21a and the abutment portion 21b, abut or closely face the horizontal piece portion 15ba of the auxiliary piece member 15b in the horizontal board material mounting portion 15, and the left and right end edges of the horizontal airtight material 17 abut against the left and right inner side surfaces of the vertical airtight material main body portion 21a due to the main body portion 17a being cut out, and the abutment portion 17b, together with the opening side piece portion 17aa that remains uncut, abut or closely face the vertical frame mounting piece portion 2ba of the mounting bracket 2b for mounting the vertical board material mounting portion 20 to the left and right vertical frames 2, which is designed to contribute to ensuring high airtightness at the end edge portions of each airtight material 17, 21.

[0025] Furthermore, a lock body 25a constituting the locking device 25 is provided on the vertical frame material on the door end side of the first panel body P1, and is configured so that the first panel body P1 in the closed position can be locked from the front side, but the lock rod 25b provided on the lock body 25a is configured so that it can be freely engaged and disengaged with the lock receiver body 25c provided on the mating member 23 by turning the key (not shown) inserted into the lock body 25a.

[0026] In the present embodiment configured as described above, when erecting the partition panel 1 that divides the interior space into a usable space S and a storage space T, board material mounting sections 15 for mounting a board material 14 made of gypsum to the upper and lower rail materials 12, 13 are formed on the upper and lower rail materials 12, 13. The board mounting sections 15 are cylindrical and include a first inner piece portion 15ab formed on a mounting piece member 15a that is attached and fixed to the upper and lower rail materials 12, 13 with screws 15ad, a second inner piece portion 15bb formed on an auxiliary piece member 15b that is attached and fixed to the mounting piece member 15a with screws 15bc, and an outer piece member 15c that is connected to the second inner piece portion 15bb. As a result, the board material 14 is enclosed and stored in the board material mounting section 15, which simplifies the structure of the board material mounting section 15 for enclosing and storing the board material 14, thereby reducing the number of parts and improving the efficiency of the assembly work. Moreover, the board material 14 enclosed and stored in the board material mounting part 15 configured in this manner is attached and fixed to the inner surface of the board material mounting part 15 by adhesive (or sticking), so that the board material mounting part 15 with the board material 14 fitted inside can be easily assembled, improving workability.

[0027] In this case, the connection of the outer piece member 15c to the first inner piece portion 15ab is made by connecting the outer piece member 15c to the bent piece portion 15ae, which is bent toward the rear in the fore-and-aft direction as the first inner piece portion 15ab.As a result, the connection structure of the outer piece member to the first inner piece portion 15ab is simplified and on-site work is also made easier.The connection between this bent piece portion 15ae and the outer piece member 15c is made by fitting the locking protrusion 15ca formed on the tip edge of the outer piece member 15c into the locking groove 15af formed on the tip edge of the bent piece portion 15ae.As a result, the connection work between the bent piece portion 15ae and the outer piece member 15c can be easily done even on-site.

[0028] In addition, a horizontal airtight material 17 that opens on the panel body P side so as to abut against the panel body 14 and provide airtightness is provided at the vertical inner end of the board material mounting portion 15.In this case, a groove 18 for the horizontal airtight material formed in the board material mounting portion 15 to accommodate the horizontal airtight material 17 can be formed in a groove shape by the vertical outer groove side piece portion 15bd and groove bottom piece portion 15be that are bent and formed at the vertical inner portion of the second inner piece portion 15bb, and the vertical inner groove side piece portion 15cb that is bent and formed at the vertical inner portion of the outer piece member 15c.As a result, the groove 18 for the horizontal airtight material can be easily formed in the board material mounting portion 15 in conjunction with forming the board material mounting portion 15. Furthermore, the groove 18 for the horizontally-oriented airtight material formed in this manner is bent so that the vertical inner portion of the second inner piece 15bb bulges toward the panel body P, and as a result, the opening side end of the vertical outer groove side piece 15bd of the groove 18 for the horizontally-oriented airtight material can be configured to have a deep groove shape biased toward the panel body P, and as a result, the horizontally-oriented airtight material 17 can be installed in a deep groove, resulting in stable installation of the horizontally-oriented airtight material 17.

[0029] In this way, when the present invention is implemented, the board material 14 is attached to one side of the upper and lower rail materials 12, 13 in the front-rear direction so as to overlap the panel body P. The attachment method for this purpose is as follows: a first screw fixing step of fixing the auxiliary piece member 15b, on which the second inner piece portion 15bb is formed, to the attachment piece member 15a, on which the first inner piece portion 15ab is formed, via a screw 15bc; a board material disposing step of disposing the board material 14 in a state where the panel body side surface 14a is adhered to the first and second inner piece portions 15ab and 15bb that are flush with each other; a board material storing step of connecting the outer piece member 15c to the first inner piece portion 15ab so as to cover the opposite panel body side surface 14b of the arranged board material 14, thereby forming a board material mounting portion 15 in which the board material 14 is enclosed and stored; a second screw fixing step of fixing the mounting piece member 15a to the upper and lower rail members 12 and 13 via screws 15ad; As a result of performing each of the above steps, the work of attaching the board material 14 to the upper and lower rail materials 12, 13 is simplified, and the efficiency of the board material attachment work is improved. Furthermore, in this case, the first screw fixing process, board material arrangement process, and board material storage process are carried out in the factory, and the second screw fixing process is carried out at the assembly site, thereby simplifying the work at the assembly site and improving work efficiency.
