Description

  The present invention relates to a profile provided with a heat-foamable member and a fitting using the same profile.

For example, in the event of a fire in a building, to prevent leakage of hot air, flames, smoke, etc. from the gaps in the building frame and joinery fence, the shape of the frame and joinery fence ( For example, a shape member in which a heating foam material is provided at a corner portion or the like to provide a fire prevention function is known (see Patent Documents 1 and 2).
When heated foam material is heated when a fire breaks out, its volume expands to form a heat insulating layer, and closes the gap between the inside of the shape member and the shape member and the adjacent member to prevent the penetration of heat and flame.
Conventionally, in order to attach a heated foam material to a shape material, for example, it is directly attached to the surface of the shape material (Patent Document 1) or attached to a dedicated attachment portion formed on the surface of the shape material (Patent Document 2). ) And the like have been used. Moreover, when attaching a heat | fever foaming material to the hollow part inner surface of a shape material, for example, a heat | fever foaming material is affixed on the support member which served also as the reinforcement, the support member is inserted from a small edge, and is fixed with the screw | thread.

FIG. 7 is a cross-sectional view showing an example of a conventional shape member that is not described in the patent literature, but in which a heating foam material is disposed in the hollow portion of the shape member.
As shown in the figure, the conventional shape member 1 is formed by attaching a heating foam material 3 to a plate-like support member 4 and inserting the support member 4 into the hollow portion 2 from the small edge of the shape member 1. 4 and the profile 1 are fastened with screws 5 (5a, 5b).
That is, the support member 4 is made of an aluminum alloy or the like, and includes an attachment surface of the heating foam material 3 and end wall surfaces 4a and 4b serving as attachment surfaces continuously provided at both ends in the width direction of the attachment surface. Both are fixed integrally to the wall surfaces 4a, 4b and the mounting holes 1a, 1b drilled in the profile 1 through screws 5 (5a, 5b).

In the case of a fire in a conventional shape 1, the heated foam material 3 attached to the support member 4 expands to fill the space between the support member 4 and the inner surface of the shape 1, for example, drains the shape 1. The air circulation part such as a hole is shielded to prevent penetration of hot air or flame, and the support member 4 can reinforce the shape member 1.
However, since the conventional shape member 1 is attached by fastening the support member 4 provided with the heating foam material 3 with the screw 5, the operation of forming the attachment holes 1a and 1b in both the shape member 1 and the support member 4 and the support The operation | work which fastens the member 4 and the profile 1 with the screws 5a and 5b is required. In addition, the arrangement position of the support member 4 is restricted by the position of the mounting hole 1 a provided in the shape member 1, the bending dimension of the support member 4, the wall thickness, and the like. It is not easy to position at a position.
Further, each time the dimension of the profile 1 to which the support member 4 is attached is changed, a new support member 4 is required.

  Therefore, it is conceivable to use a double-sided tape instead of using the support member 4 and attach the heating foam material 3 with the double-sided tape attached to the inner surface of the hollow portion 2 of the profile 1. However, when a double-sided tape is used, the heating foam material 3 is necessarily disposed along the inner surface of the hollow portion 2 of the shape member 1, and at an arbitrary position away from the inner surface of the hollow portion 2. Cannot be placed. For this reason, the heating foam material 3 cannot be set at an optimum location in the design, and when a sticking error occurs, it is difficult to correct it.

The above is a case where the heating foam material 3 is arranged in the hollow portion 2 of the profile 1, but the heating foam 3 is arranged mainly along the corner (corner portion) of the profile 1 to cause a fire. In the arrangement structure of the heating foam material 3 for closing the gap of the corner portion when it occurs, since the heating foam material 3 is attached to the shape material 1, conventionally, double-sided tape (FIG. 7), caulking, screwing, etc. are used. It is used.
However, when this arrangement structure is adopted, in addition to the need for a double-sided tape or the like as means for attaching the heating foam material 3 to the profile 1, the heating foam material 3 is affixed separately to the intersecting wall surfaces at the corners. Work, caulking and screwing are necessary.
As described above, the heating foam material 3 is conventionally used when the heating foam material 3 is attached to the hollow portion 2 of the shape member 1 or when it is attached to the outer surface side of the shape material 1 such as a corner portion. There is a problem that not only the cost and the work are complicated, but also a means for pasting or fastening and a work related thereto are required.

It is characterized in that it is mounted (inserted).
In addition, the term “profile” here generally includes building members (columns, beams, other frame materials, etc.) and joinery members (open frames, eaves, vertical, partition panels, etc.). Used as a simple term.

Hereinafter, although the profile which concerns on embodiment of this invention is demonstrated, here, when mounting the plate-shaped support member prepared by sticking a heating foam material on a profile (to the profile of a heating foam) The arrangement structure (1)) and the case where the heating foam material itself is directly attached to the shape (the arrangement structure (2) of the heating foam material on the shape) will be described separately.
<Arrangement structure of heated foam material on shape (1)>
FIG. 1 shows different mounting structures of the support member 30 in the hollow portion 12 of the profile 10, and FIGS. 1A to 1G show a state in which the heating foam material 20 is arranged in the hollow portion 12 of the profile 10 having a substantially rectangular cross section. It is sectional drawing shown.

In the hollow portion 12 of the profile 10 shown in FIG. 1A, a screw hole 13 (1) extending in the longitudinal direction of the inner surface of the hollow portion of the profile 10 is provided as an existing attached structure portion.
In this shape member 10, both ends of the heat-foamable member (here, the plate-like support member 30 having the heat-foamable material 20 attached to the upper surface in the figure) are inserted into the screw holes 13 (1) from the small openings of the shape member 1. Attached.
In this mounting structure, the cross-sectional shape of both ends of the plate-like support member 30 is rectangular and does not match the circle of the screw hole 13 (1), but the plate-like support member 30 is attached and held. As in the prior art, it is not necessary to perform an operation such as tightening and integrating with the screw hole 13 (1) by caulking or the like.
In the illustrated example, the heating foam material 20 is attached only to the upper surface of the plate-like support member 30. However, you may affix only on a lower surface as needed, or may affix on both upper and lower surfaces. This is the same in other embodiments.

FIG. 1B is a cross-sectional view of the profile 10 in which the heating foam material 20 is disposed in the hollow portion 12 as in FIG. 1A.
As shown in the figure, the cross-sectional shape of the support member 30 includes a flat plate portion 34 serving as a mounting surface of the heating foam material 20, and a step portion (side wall) 32 bent downward in the figure at both ends in the width direction of the flat plate portion 34. It has a U-shaped cross section as a whole.
In the present embodiment, by changing the height (or vertical width) h of the side wall 32 of the support member 30, the distance from the opposed inner surface of the profile 10 of the heating foam 20 is changed and disposed at a suitable position. be able to.

Further, the support member 30 shown in FIG. 1B is formed in a circular shape whose end cross-sectional shape matches the cross-sectional shape of the screw hole 13 (1), and slightly upward of the screw hole 13 (1) on the left side of the drawing. The circular shape of the end portion is formed obliquely downward according to the opening direction. The support member 30 shown in FIG. 1B is slightly different from the support member 30 shown in FIG. 1A in this respect.
By configuring the end cross-sectional shape in this way, the support member 30 can be mounted in a stable state without rattling only by inserting the support member 30 into the screw hole 13 (1) of the shape member 10.

FIG. 1C is a cross-sectional view of a profile 10 in which a heating foam material 20 is disposed in a hollow portion 12 similar to FIG. 1A.
The shape member 10 in FIG. 1C and the shape member 10 in FIG. 1A are supported by a portion of the screw hole 13 (1) in FIG. 1A having two upper and lower ribs or protrusions 13 (2) in FIG. 1C. Both ends of the member 30 are inserted into the ridge 13 (2) in FIG. 1C. Since it is the same as that of FIG. 1A other than that, description about FIG. 1A is used here.
FIG. 1D is a cross-sectional view of a profile 10 in which a heating foam material 20 is disposed in a hollow portion 12 similar to FIG. 1A. Here, the end in the width direction of the support member 30 is inserted into a recess (or pocket) 13 (3) provided on the left side of the hollow portion 12 of the profile 10 and a protrusion 13 (2) provided on the right side, respectively. Yes. Here, the shape of the protruding portion 13 (2) is formed wider in the vertical direction in the drawing than that of FIG. 1C, and both end portions of the support member 30 are respectively provided with the recessed portion 13 (3) and the protruding portion. It is formed in a T-shaped cross section that matches the shape of 13 (2). Other configurations are the same as those in FIGS. 1A and 1C.

FIG. 1E is a cross-sectional view of a profile 10 in which a heated foam material 20 is disposed in a hollow portion 12 similar to FIG. 1A.
In the profile 10 shown in FIG. 1E, the screw hole 13 (1) is formed at a position shifted vertically in the right and left in the drawing. Correspondingly, in the illustrated example, the support member 30 is formed with a step portion (side wall) 32 (1) bent downward near the right end portion in the cross section. Therefore, in the state where the support member 30 is inserted into the screw hole 13 (1), the heating foam 20 is disposed at a position where the level difference is eliminated (horizontal position in the figure).

FIG. 1F is a cross-sectional view of a profile 10 in which a heating foam material 20 is disposed in a hollow portion 12 similar to FIG. 1E.
The cross-sectional view of the profile 10 shown in FIG. 1F is similar to that of FIG. 1E, but the cross-sectional shape of the end portion of the support member 30 is circularly formed in accordance with the cross-sectional shape of the screw hole 13 (1) here. In that respect, it is the same as that shown in FIG. 1B, and the other structure is the same as that shown in FIG. 1E.
FIG. 1G is a cross-sectional view of a profile 10 in which a heated foam material 20 is disposed in a hollow portion 12 similar to FIG. 1F.
The shape member 10 shown in FIG. 1G is the same as that shown in FIG. 1E, but here, the support member 30 is not provided with side walls (steps), and the plate-like support member 30 is diagonal in the figure. Is installed. Further, the cross-sectional shape of the end portion of the support member 30 is formed in a circular shape corresponding to the cross-sectional shape of the screw hole 13 (1), similar to that shown in FIG. 1F.

  As mentioned above, although the attachment structure to the shape material 10 of the heating foam material 20 in the hollow part 12 was demonstrated with reference to FIG. 1A-1G, these attachment structures are the shape 10 and the existing attached structure part as it is. Utilizing this, both end portions of the plate-like support member 30 to which the heating foam material 20 is attached are inserted and attached thereto. Therefore, compared with the conventional mounting structure, there is an advantage that additional processing such as mounting holes, additional fixing members such as screws, and additional operations such as fastening of screws are not required.

It should be noted that the shape of both ends of the support member 30 can be inserted and fixed without particularly matching the cross-sectional shape of the attachment structure portion, but it is simple simply by matching the shape of both ends of the support member 30 to the cross-sectional shape of various attachment structure portions. By performing an appropriate process, it can be more reliably inserted and fixed to the attached structure portion.
When there is a shift in the relative position of the attached structure portion, the heating foam material 20 can be arranged at various positions in the hollow portion 12 of the profile 10 by using the shift.

As for the attachment structure in the hollow part 12 of the heating foam material 20 demonstrated above, the supporting member 30 provided with the heating foam material 20 is used for all. This support member 30 functions as a reinforcing member for the shape member in the event of a fire. Therefore, there is a surface that contributes to the improvement of the function as a fire-proof shape material. However, in this structure, it is necessary to prepare a member different from the heating foam material and attach the heating foam material thereto.
In view of this, it is conceivable that the heating foam material itself is attached to the attached structure portion of the shape member 10 by utilizing the rigidity of the heating foam material.
Next, the embodiment will be described.

<Arrangement structure of heated foam material on the shape (2)>
First, the heated foam material itself will be described.
FIG. 2A is a cross-sectional view of the heating foam material 22 that is directly attached to the attached structure portion of the profile member 10, and FIG. 2B is a partial cross-sectional view showing the main part thereof.
That is, the heating foam material 22 shown in FIGS. 2A and 2B has a shape in which both ends in the width direction match the cross-sectional shape of the attached structure portion formed inside the hollow portion 12 of the shape member 10 (in the illustrated example, a circular cross section). Is formed. Moreover, the same shape part 22 (1) as both ends is formed in the longitudinal direction of a plurality of strips at intervals in the width direction (for example, at equal intervals).

FIG. 2B is an enlarged view of a part of FIG. 2A, in particular a section 22 (1) having a circular cross section.
As shown in FIG. 2B, a slit-like (for example, V-shaped cross-section) thin portion (referred to as weakened portion 22 (2)) is formed adjacent to the circular portion 22 (1). This is to cut the heating foam material 22 along the circular section 22 (1) so that the width can be freely adjusted.
By configuring the heating foam material 22 in this way, when the heating foam material 22 is disposed in the hollow portion 12 of the shape member 10, the width can be freely selected according to the width of the hollow portion.

FIG. 2C is a diagram illustrating a cross-sectional shape of both end portions of the heating foam material 22. As shown in the figure, the cross-sectional shape of both ends of the heating foam material 22 is a shape in which a cut is made from the tip of the circular cross section (FIG. 2C (1)), and a shape in which the circular cross section is hollowed out in accordance with the circular cross section (see FIG. 2C (2)), or a shape in which the end side of the circular cross section is cut into a flat surface (FIG. 2C (3)), and other than a circular cross section, for example, a rectangular shape (FIG. 2C (4) in FIG. 2C (4) )), T-shaped section (FIG. 2C (5)), wedge-shaped section (FIG. 2C (6)), and the like. As a matter of course, the cross-sectional shape of the end portion is not limited to these, and any shape can be adopted as long as it can be accommodated in the structural portion formed on the inner surface of the hollow portion 12 of the profile 10.
Of the cross-sectional shapes at both ends described above, the shape that is difficult to form at intervals in the width direction of the heated foam material 22 is preferably a shape that can be formed after cutting.

FIG. 3 is a cross-sectional view showing a state in which the heating foam material 22 described above is actually attached to the shape member 10.
FIG. 3A is a cross-sectional view showing a state in which the heating foam material 22 is arranged in the hollow portion 12 of the shape member 10 and the corner (corner portion) on the surface side (surface portion). 3B and 3C are cross-sectional views showing a state in which the heating foam material 22 is disposed in the hollow portion 12 of the profile 10.
In FIG. 3A, the heating foam material 22 is disposed in a state where the end portion formed in a circular cross section is inserted into the screw hole 13 (1) in the hollow portion 12 and bent upward in the drawing as an example. Has been.

Further, in the corner portion of the profile member 10, the heated foam material 22 is hollow in the profile member 10 and the screw hole 13 (1) a formed on the wall surface (flange surface) 10 (1) extending from one side surface of the profile member 10. In the example shown in the figure, outward from the corner portion, like the heated foam material 22 in the hollow portion 12, with the end portions inserted into the ridge portions 13 (2) a formed on the outer surface of the side wall constituting the portion 12, respectively. It is mounted in a bent state. Of course, there may be a state of bending inward.
The heating foam material 22 shown in FIG. 3B is the same as the heating foam material 22 shown in FIG. 3A. However, since the mounting width of the profile 10 is short, the degree of bending in a state where the profile 10 is attached to the hollow portion 12 of the profile 10. Is getting bigger. Since the heating foam material 22 can be attached to the shape member 10 in such a bent state, the same heating foam material 22 can be attached to the shape material 10 having different dimensions.

The length of the heating foam material 22 may be adjusted to an appropriate length at the weakened portion 22 (2) shown in FIG. 2B.
Moreover, since the heating foam material 22 can be cut | disconnected suitably in the weakening part 22 (2), the grade of the bending in the state with which the shape material 10 was mounted | worn (the position in the hollow part 12, the amount of the heating foam material 22) Can be adjusted arbitrarily.
The heated foam material 22 shown in cross section in FIG. 3C is cut to an appropriate length (solid line portion) at the weakened portion 22 (2) as shown in the upper part, and the profile shown in the lower part. The state attached to the 10 hollow parts 12 is shown. Here, the heating foam material 22 is bent downward in the figure, but this depends on the position where the attached structure portion (the screw hole 13 (1)) of the profile 10 exists. The other points are the same as those shown in FIG. 3B.

  The arrangement structure (1) of the heating foam material 22 on the shape material 10 and the arrangement structure (2) of the heating foam material 22 on the shape material 10 are described above for the hollow portion 12 and the corner portion of the shape material 10, respectively. However, the mounting structure for mounting the heated foam material to the attached structure portion of the profile is not limited to that described above, and various modifications and combinations are possible.

Next, the example of a change and a combination are demonstrated.

6D, the bulging portion 22 (3) at the center of the heating foam material 22 shown in FIG. 6A (2) is inserted into the screw hole 13 (1) provided at the position where the wall surface of the corner portion intersects. An example is shown in which a free end is mounted in contact with the intersecting wall surfaces of the corner portion using the flexibility and moderate rigidity of the heating foam 22.
According to the present embodiment, conventionally, in the corner portion, for example, a double-sided adhesive material is used, and separate heating foam materials are mounted on the intersecting wall surfaces, whereas a single heating foam material 22 is used. Has an advantage that it can be securely attached by mechanical means without using a double-sided adhesive.

Although each embodiment of the present invention has been described above, the heated foam material according to each embodiment has the following effects in common. That is,
The heating foam material or the support member provided with the heating foam material can be fixed as it is when the attached structure portion of the profile is inserted as a guide surface. Therefore, the bending process, the fixing hole process, and the screw fastening for forming the screw mounting surface of the support as in the prior art become unnecessary, and the number of man-hours can be reduced. In addition, when attaching a heated foam material or a support member provided with a heated foam material to a profile, the attachment counterpart does not matter the position of the attached structure (ribs, screw holes, etc.), so a wide variety of cross-sectional shapes It can be applied to any shape material.
Since the heated foam material can be disposed, for example, in the middle position of the hollow portion depending on the position of the bis-hole of the shape member, it is possible to quickly fill with the heated foam material expanded in the hollow portion when a fire occurs.
Regardless of the position of the attached part of the profile, the position of the heated foam material can be positioned at a desired position in the foam region. Therefore, the freedom degree of the design regarding arrangement | positioning of a heating foam material improves.
When mounting the heated foam material, it does not use double-sided tape, caulking, or screwing for directly attaching to the shape material, so that it can be easily mounted again and maintenance is improved.

When the heated foam material itself is inserted into the attached structure part of the profile, in addition to the above-mentioned effects, the flexibility of the heated foam material is used to apply the heated foam material to profiles with different mounting widths. It can be bent and mounted, or the heated foam can be cut into an arbitrary width and used. Therefore, without preparing a plurality of types of heating foam materials having different widths, it is possible to attach to shapes having different prospects and finding dimensions with a single width heating foam material, and it is possible to reduce the types of heating foam materials.
By using the shape member described above as a frame material for a joinery, a saddle or the like, a joinery having excellent fire resistance can be obtained. Moreover, the heating foam material demonstrated above may be inserted over the hollow part full length of a shape member, or may be inserted partially and used.
In the above description, the heating foam material is attached to the support member, but a flame shielding effect can be expected even if the heating foam material is not attached.
