The tip surface 4b constituting one short side of the maximum outer shape is a flat surface constituting a part of the opening 4B when assembled as the fixed frame 4A.
In addition, a base end surface 4d parallel to the front end surface 4b is formed at a position W from the front end surface 4b.
On the outer surface of the fixed frame member 4 sandwiched between the distal end surface 4b and the base end surface 4d, a fixed portion 4a that is a plane portion that is separated by a distance T and is parallel to each other, and an outer plane portion 4f are formed.
The fixing part 4a is provided to overlap and fix the outer edge of the sheet member 3.

  Hereinafter, when the cross-sectional shape of the fixed frame member 4 is described, the direction along the long side may be referred to as the long side direction, and the direction along the short side may be referred to as the short side direction.

  On the fixed portion 4a, a linear groove 4g and a rectangular groove 4j are formed in this order from the distal end surface 4b side toward the proximal end surface 4d opposite to the distal end surface 4b.

The linear groove 4g is a groove part for holding a part of the sheet member 3 fixed to the fixing part 4a in a pressed state. In this embodiment, the groove cross section is a semicircular shape, and the fixed frame member 4 It is formed along the longitudinal direction.

In addition, the rectangular groove 4j can employ | adopt the concave groove which has appropriate cross-sectional shapes other than a rectangle depending on the required amount of meat theft. Also, if there is no need for meat theft, it can be omitted.

Further, the outer shape of the fixed portion 4a on the back surface side of the fixed frame member 4 is the outer flat surface portion 4f from the distal end surface 4b to the base end surface 4d, and a distance T _4e from the fixed portion 4a (however, T _4e <T). It has the inner side plane part 4e which is a plane part spaced apart in parallel. Thus, a step is formed on the back side of the fixed portion 4a with the middle portion in the long side direction as a boundary.

The outer flat surface portion 4f is formed with a connecting groove portion 4c that is a groove portion for inserting and fixing a connecting member 6 described later along the longitudinal direction of the fixed frame member 4.
The groove shape of the connecting groove 4c is a rectangular shape in which the inner cross section of the groove has a width in the long side direction of W _4c (W _4c <W) and a width in the short side direction of T _4c (however, T _4c <T).

Moreover, the linear groove | channel 4h is formed in the edge part of the inner side plane part 4e adjacent to the outer side plane part 4f.
The linear groove 4h is a fitting groove for slidably fitting a pressing member 5 to be described later, and in this embodiment, the groove cross-section is a semicircular shape along the longitudinal direction of the fixed frame member 4 Is formed.

  The fixed frame member 4 having such a configuration can be formed, for example, by extruding an aluminum alloy.

The connecting member 6 is a member that connects the two fixed frame members 4 with which the butted surfaces 4k are in contact with each other.
The configuration of the connecting member 6 is not particularly limited as long as the fixed frame members 4 can be connected to each other. However, in the present embodiment, as an example, as shown in FIG. 2B, in the connecting groove portion 4c of the fixed frame member 4 to be connected. An L-shaped metal fitting having a rectangular cross section that can be inserted into the two is extended in two directions orthogonal to each other.
In this embodiment, the connecting member 6 is fixed to each fixed frame member 4 by being screwed to each fixed frame member 4 with a screw 7 after being inserted into each connecting groove 4c.

The pressing member 5 is a member that is detachably fixed to each fixed frame member 4 of the fixed frame 4A to which the sheet member 3 is fixed, and applies tension to the sheet member 3.
In the present embodiment, the pressing member 5 has a cross section shown in FIGS. 3 and 4B in one direction (a direction perpendicular to the paper surface in FIGS. 3 and 4A), excluding both ends. It may be a member having an elongated shape extended in some cases.
As shown in FIG. 2 (a), the both ends of the pressing member 5 in the longitudinal direction are diagonal to the longitudinal direction so as to form corners that meet the ends of the other pressing members 5 and intersect at right angles. A butting surface 5k inclined by 45 ° is provided.

As shown in FIG. 3, the cross-sectional shape in the direction orthogonal to the longitudinal direction of the pressing member 5 has a holding plate portion 5 a having a size covering the side surface of the fixed frame member 4 on the fixed portion 4 a side and the base of the fixed frame member 4. The side plate portion 5b sized to cover the end surface 4d, the flat plate portion 5c sized to cover the inner flat surface portion 4e of the fixed frame member 4, and extended from the tip of the holding plate portion 5a to the flat plate portion 5c side. Plate-like part 5d (pressing part).
The distance between the pressing plate portion 5a and the flat plate portion 5c is slightly wider than the distance _T4e between the fixed portion 4a and the inner flat surface portion 4e in the fixed frame member 4.
Further, the length of the inner surface (the surface facing the flat plate portion 5 c) of the pressing plate portion 5 a from the side plate portion 5 b to the plate-like portion 5 d in the cross section orthogonal to the longitudinal direction of the pressing member 5 is the length of the fixed frame member 4. It is slightly longer than the side width W.

Therefore, when the pressing member 5 is inserted in a state where the base end surface 4d of the fixed frame member 4 is brought close to the side plate portion 5b and the fixing portion 4a of the fixed frame member 4 is opposed to the pressing plate portion 5a (hereinafter referred to as insertion) The outer periphery of the fixed frame member 4 can be enclosed in a J-shape.
For this reason, the area surrounded by the pressing plate portion 5a, the side plate portion 5b, and the flat plate portion 5c of the pressing member 5 is a fitting groove 5j (removably fitted to the fixed frame member 4 serving as the outer peripheral portion of the fixed frame 4A). (See FIG. 4B).
In this inserted state, the plate-like portion 5d protrudes from the front end surface 4b of the fixed frame member 4, and the inner surface 5e of the plate-like portion 5d protrudes ahead of the front end surface 4b.

Moreover, in this embodiment, the plate-shaped part 5d is made into the flat plate shape which has a thickness comparable as the pressing board part 5a. For this reason, the outer surface 5f of the plate-like portion 5d is inclined with respect to the presser plate portion 5a similarly to the inner surface 5e.
A protrusion 5i having a circular cross section protruding from the outer surface 5f is formed along the longitudinal direction of the pressing member 5 at the tip of the plate-like portion 5d. By having the ridge 5i, the tip of the plate-like part 5d is reinforced.

On the inner surface side of the pressing plate portion 5a, a semicircular shape in which a cross-sectional shape perpendicular to the longitudinal direction of the pressing member 5 can enter the linear groove 4g at a position facing the linear groove 4g of the fixed frame member 4 in the inserted state. A protruding ridge portion 5 g is formed along the longitudinal direction of the pressing member 5.
On the inner surface (surface toward the pressing plate portion 5a) side of the flat plate portion 5c, a cross-sectional shape perpendicular to the longitudinal direction of the pressing member 5 is linear at a position facing the linear groove 4h of the fixed frame member 4 in the inserted state. A semicircular ridge portion 5 h that can enter the groove 4 h is formed along the longitudinal direction of the pressing member 5.
For this reason, when the pressing member 5 inserts the fixed frame member 4 into the fitting groove 5j, the pressing member 5 causes the protruding portion 5h to enter the linear groove 4h of the fixed frame member 4 so that the linear groove 4h is guided into the guide groove. As described above, it is possible to insert the fixed frame member 4 along the longitudinal direction.

  The pressing member 5 having such a configuration can be formed, for example, by extruding an aluminum alloy.

Next, a method for assembling the smoke proof hanging wall frame material 2 will be described.
FIGS. 5A and 5B are schematic process explanatory views for explaining the assembly process of the fixed frame assembly in the embodiment of the present invention. FIG. 6 is a schematic cross-sectional view illustrating the operation of the smoke-proof hanging wall frame material according to the embodiment of the present invention. FIG. 7 is a schematic process explanatory diagram illustrating the assembly process of the smoke-proof hanging wall according to the embodiment of the present invention.

First, the connecting member 6 is inserted into the connecting groove 4c at each end of the four fixed frame members 4, and the butted surfaces 4k adjacent to each other are brought into close contact with each other to form a rectangular frame.
Then, the connecting members 6 are fastened to the fixed frame members 4 by screws 7 to fix the positional relationship. As a result, as shown in FIGS. 2A and 2B, the fixed frame 4A is assembled.

Next, the outer edge portion of the sheet member 3 is fixed on the fixing portion 4a of the fixing frame 4A. Here, the outer edge portion of the sheet member 3 is a space between the rectangular region and the outer periphery of the sheet member 3 when a rectangular region overlapping the opening 4B of the fixed frame 4A is secured at the center of the surface of the sheet member 3. It means a band-like region to be formed. In the present embodiment, it is a belt-like region that circulates along the rectangular outer shape of the sheet member 3.
In this embodiment, as shown in FIG. 5A, a double-sided tape 3a is attached to the outer edge of the sheet member 3, and the double-sided tape 3a is fixed to the fixed frame 4A as shown in FIG. 5B. Press and affix to the part 4a. At this time, the sheet member 3 is pasted so that no sagging or wrinkles occur. For example, the sheet member 3 may be attached while being supported by a flat jig, an attaching roller, or the like, or may be attached while the outer periphery of the sheet member 3 is pulled.
In this way, a fixed frame assembly 4C (see FIG. 5B) in which the sheet member 3 is fixed to the fixed frame 4A is formed.

Next, the pressing member 5 is fixed to the fixed frame assembly 4C.
The pressing member 5 may be fixed by, for example, screwing or the like, but in this embodiment, the pressing member 5 is fixed by fitting the pressing member 5 to the fixed frame member 4.
First, as shown in FIG. 2A, the pressing members 5A, 5B, and 5C are fixed to the fixed frame member 4 constituting the three sides of the fixed frame assembly 4C.
That is, the protrusions 5 h of the pressing members 5 A, 5 B, and 5 C are aligned with the linear grooves 4 h of the fixing frame members 4 of the respective fixing counterparts, and the respective fitting grooves 5 j are the outer circumferences of the fixing frame members 4. An insertion state is formed by externally fitting the end portion in the longitudinal direction so as to be fitted to the portion. In this state, for example, each pressing member 5 is moved along the longitudinal direction of the fixed frame member 4 in the order of the pressing members 5 </ b> A, 5 </ b> B, 5 </ b> C, and each pressing member 5 is moved over the entire outer peripheral portion of the fixed frame member 4. Fit.

In such an inserted state, as shown in FIG. 6, the plate-like portion 5d of the pressing member 5 is pressed against the sheet member 3 stretched over the opening 4B. On the other hand, since the sheet member 3 has flexibility, the sheet member 3 bends to the outer flat surface portion 4f side than the fixing portion 4a by this pressing, so that tension is applied to the sheet member 3.
Thus, in this embodiment, the sheet | seat member 3 contact | abuts with the inner surface 5e of the plate-shaped part 5d extended in the longitudinal direction of the press member 5, and is uniformly pressed along a longitudinal direction. For this reason, the sheet member 3 is evenly stretched and stretched flat without causing local sagging or wrinkles.
At this time, the protruding portion 5g of the pressing member 5 enters the linear groove 4g of the fixed frame member 4 with the sheet member 3 interposed therebetween, and presses the outer edge portion of the sheet member 3 linearly. For this reason, the sheet member 3 is more firmly fixed.
Thus, every time the pressing member 5 is fitted, the outer edge portion of the sheet member 3 is more firmly fixed to the fixing portion 4a, and the tension of the sheet member 3 increases.

As shown in FIG. 7, when the pressing members 5A, 5B, and 5C are fitted into the three sides of the fixed frame assembly 4C, the pressing members 5D are fitted so as to be pushed from the outer peripheral side toward the inner peripheral side of the fixed frame assembly 4C. Include.
Accordingly, the sheet member 3 is fixed in a state where tension is applied by being pressed by the inner surfaces 5e of the four pressing members 5.
Thus, the smoke-proof hanging wall 1 is assembled.
As shown in FIG. 1, a plurality of such smoke-proof hanging walls 1 can be connected to each other and fixed to a ceiling 50 and a wall 51.
Further, by performing the above operations in reverse, the smoke-proof hanging wall 1 can be disassembled and maintained without using a dedicated jig or the like. When exchanging the sheet member 3, if the sheet member 3 in the opening 4 </ b> B is cut first, the reaction force acting on the pressing member 5 from the sheet member 3 is eliminated. It becomes easier.

  Thus, according to the frame member 2 and the smoke-proof hanging wall 1 of the present embodiment, the pressing member 5 is fixed by fixing the pressing member 5 after fixing the sheet member 3 to the fixed frame 4A. Since the plate-like portion 5d presses the sheet member 3 and tension is applied to the sheet member 3, the sheet member 3 can be easily assembled while suppressing wrinkles of the sheet member 3.

[Modification]
Next, a modification of this embodiment will be described.
FIG. 8 is a schematic cross-sectional view showing a main part of a smoke-proof hanging wall according to a modification of the embodiment of the present invention. FIG. 9 is a schematic cross-sectional view of a fixed frame member of a smoke-proof hanging wall frame material according to a modification of the embodiment of the present invention.

As shown in FIGS. 1 and 8, the smoke-proof hanging wall 11 and the smoke-proof hanging wall frame material 12 of this modification are respectively pressed by the smoke-proof hanging wall 1 and the smoke-proof hanging wall frame material 2 of the above embodiment. Instead of the member 5, a pressing member 15 is provided. Hereinafter, a description will be given focusing on differences from the above embodiment.
As shown in FIGS. 8 and 9, the pressing member 15 has an oval or elliptical cross section instead of the protrusion 5i of the pressing member 5 of the above embodiment, and protrudes from the outer surface 5f and the inner surface 5e. The projected ridge part 15i is provided. The protruding portion 15i is formed along the longitudinal direction of the pressing member 15 (the direction perpendicular to the paper surface of FIGS. 1 and 8).

According to this modification, as shown in FIG. 8, when assembled as the smoke-proof hanging wall 11, the sheet member 3 comes into contact with the leading end portion in the protruding direction of the protruding portion 15 i protruding from the inner surface 5 e. And pressed. For this reason, the sheet member 3 is stretched so as to be separated from the inner surface 5e between the front end surface 4b and the protruding portion 15i.
In the embodiment described above, the sheet member 3 is pressed flat by the inner surface 5e. In the present modification, a narrow area is formed by the cylindrical surface formed at the end of the protruding portion 15i in the protruding direction. Is different in that it is pressed linearly.
Therefore, also in this modified example, the ridge portion provided on the plate-like portion 5d of the pressing member 15 by fixing the pressing member 15 after fixing the sheet member 3 to the fixed frame 4A, as in the above embodiment. Since 15i presses the sheet member 3 and tension is applied to the sheet member 3, the sheet member 3 can be easily assembled while suppressing wrinkles of the sheet member 3.

In this modification, since the contact area is smaller than that of the above embodiment, the sheet member 3 bites into the sheet member 3 and is pressed more firmly. Moreover, unevenness of the pressing force is reduced.
In addition, according to the present modification, the tension applied to the sheet member 3 can be easily changed depending on the protrusion amount of the ridge portion 15i that contacts the sheet member 3, and therefore, for example, the thickness and the elastic modulus are different. When pressing the sheet member 3, it is possible to adopt a shape in which only the protruding amount of the protrusion 15i is changed according to the tension required for each. For this reason, the design and design change of the pressing member 15 used for various sheet members 3 are facilitated.
Moreover, since it can be utilized in common only by changing a part of the metal mold for manufacturing the pressing member 15, the manufacturing cost of the pressing member 15 can be reduced.

  In the above description of the embodiment and the modification, the example in which the pressing member is fitted and fixed to the fixing frame has been described. However, the fixing method is not limited to this as long as the pressing member can be detachably fixed. For example, the pressing member may be fixed to the fixed frame by screwing or the like. In this case, for example, the fitting groove 5j of the pressing member 5 can be deleted, and for example, a shape in which the side plate portion 5b and the flat plate portion 5c are omitted can be adopted.

  Further, in the description of the above-described embodiment and the modified examples, the description has been given of the example in the case where the butted surfaces inclined in the longitudinal direction are formed at both ends of each of the fixed frame members 4 and the pressing members 5 (15). The shapes of the inclined surfaces are not limited as long as they can be brought into contact with each other.

  In the above description of the embodiment and the modification, the example in which the pressing portion includes the plate-like portion 5d has been described. However, the pressing portion has a surface on the side in contact with the sheet member 3 than the fixing portion 4a. What is necessary is just to protrude, and the shape on the opposite side is not specifically limited. Therefore, for example, the outer surface 5 may be aligned with the outer surface of the presser plate portion 5a or may protrude outward from the presser plate portion 5a.

  In the above description of the embodiment and the modification, the example in which the sheet member 3 is fixed by the double-sided tape 3a is described, but this is an example, and the fixing method of the sheet member 3 is limited to this. Not. For example, adhesion by an adhesive may be used, or a locking projection is provided on the fixing portion 4a of the fixed frame member 4, and a through-hole that is fitted to the locking projection is provided in the sheet member 3 so that the concave and convex portions are fitted. It is good also as a structure. In this case, the sheet member 3 can be easily attached to and detached from the fixed frame member 4.

  In addition, the components described in the above embodiments and modifications can be implemented by being appropriately combined or deleted within the scope of the technical idea of the present invention.
