DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a roof structure in which a roof is filled with a foam material.

[0002]

2. Description of the Related Art In general, there is known a roof structure of a bay window which is composed of a parting material and a surface material and is filled with a foam material. In this type of conventional roof structure, for reinforcement,
A structure in which a bracket is provided inside a roof so as to abut against a surface material has been proposed.

On the other hand, lightweight foam concrete (“AL
C ") or a building made of reinforced concrete (" RC ") requires a bay window that fits into a substantially rectangular opening. In this case, the roof back plate must be formed in a substantially rectangular shape. To this end, the roof surface material generally has a single-flow roof structure in which the vertical width of the hanging portion is formed larger on the skeleton side than on the outside.

[0004]

However, in the roof structure in which the bracket is provided inside the roof so as to abut against the surface material, the foam material shrinks after filling with the foam material, and the roof material other than the surface material to which the bracket abuts. There is a problem that so-called "sink" occurs in the surface material portion, and unevenness is formed on the surface material, thereby deteriorating the quality of the roof structure.

In the case of a single-flow roof structure as described above, the vertical width of the hanging portion of the surface material is generally larger on the skeleton side than on the outer side. In the one-way roof structure, the connection between the hanging part of the surface material and the parting material is conventionally made by screws. However, screwing work is difficult and has a poor design appearance.

[0006] In order to solve this problem, in the case of a roof with a ridge structure, a rising portion is formed in a hanging portion of the surface material of the roof,
It is proposed that the rising portion is engaged with the engaging portion of the parting material, and the rising part is caulked to fix the surface material and the parting material.

In this case, a cushioning material is interposed between the surface material and the parting material, and at the stage of engaging the rising part with the engaging part of the parting material, the surface material is compressed so as to compress the cushioning material. It is common to use the restoring force of the cushioning material to engage the rising portion with the engaging portion of the parting-off member after pushing it into the parting-off member side.

However, when the above method is used for a one-sided roof structure, a considerably large restoring force of the cushioning material is required in a portion of the skeleton having a large vertical width of the hanging portion of the surface material. There is a problem that it becomes possible.

Accordingly, a first object of the present invention is to solve the above-mentioned problem and to provide a roof structure in which unevenness is not formed on a surface material of a roof.

A second object of the present invention is to provide a roof structure which can easily connect a hanging part of a surface material and a parting material in a one-way roof structure, and can improve the appearance in design. To provide.

[0011]

According to a first aspect of the present invention, there is provided a roof comprising a parting material and a surface material, and a roof filled with a foam material therein. A rising portion is formed, the rising portion is engaged with the engaging portion of the parting member, and a bracket is provided inside the roof. At least the rising portion and the bracket are provided between the bracket and the surface material. A gap larger than the margin of engagement with the engaging portion is formed, and a cushion material is provided in this gap to fill the gap.

According to the present invention, since the bracket does not abut on the surface material, when the foam material is filled, even if the foam material shrinks, "sink" occurs almost uniformly over the entire surface material. As described above, only the portion where the bracket abuts does not become high, and no irregularities are formed on the surface material.

[0013]

[0014]

[0015]

According to a second aspect of the present invention, there is provided a roof comprising a parting material and a surface material, wherein a vertical width of a hanging part of the surface material is formed larger on the skeleton side than on the outside side. A rising portion is formed in the hanging portion of the surface material, and the rising portion is engaged with the engaging portion of the parting material, and the side of the surface material that is closer to the skeleton side of the hanging material is set in advance in the parting material.
And the inside of the roof is filled with a foam material at a fixed position .

According to the present invention, the space between the part close to the skeleton side of the hanging part of the surface material and the parting material is fixed by the fixing member. The fixing tool is made of, for example, a screw and allows the screw to penetrate between holes formed at predetermined positions.

According to this, since the surface material is reliably pushed up to the predetermined position, the work of riveting the surface material to, for example, the back plate or the like becomes easy.

Further, on the side surface B, hanging portions 51 and 53 hanging substantially vertically are integrally formed. As shown in FIG. 3, rising portions 51A and 53A that are bent inward are formed in the hanging portions 51 and 53, and the rising portions 51A and 53A of the hanging portions 51 and 53 are formed.
53A is locked to the engaging portion 33A of the parting material 33.

That is, as shown by the alternate long and short dash line in FIGS. 3A and 3B, the surface material 31 has an arrow X corresponding to a dimension larger than the margin δ1 between the rising portions 51A, 53A and the engaging portion 33A.
After being once pushed down in the direction, the rising parts 51A, 53A and the engaging part 33A are locked by being displaced in the direction of the arrow Y, and then the rising parts 51A, 53A are swaged in the direction of the arrow Z. 33.

Then, the surface member 31, the top plate 34, the back plate 36 and the like are fixed to each other via a plurality of rivets 44. A bracket 55 for reinforcement is provided in a space 38 surrounded by these, and in the space 38, for example, a urethane-based foamed material made of isocyanate, polyol, or the like, or a phenol resin, a neutralizing agent, a curing agent, or the like. A phenolic resin foam or the like is filled.

This foam material is injected through an injection port 100 formed in the back plate 36. Inside the inlet 100, a cover plate 1 larger than the size of the inlet 100 is provided.
01 is provided. The cover plate 101 is fixed at its upper edge by a tape, and the cover plate 101 is swingably supported by the back plate 36. An elliptical gas vent 103 is formed in the back plate 36 at a position away from the inlet 100, and a cover plate 105 larger than the size of the gas vent 103 is provided inside the gas vent 103. Can be The cover plate 105 has its upper edge fixed with tape, and the cover plate 105 is attached to the back plate 36 so as to be swingable.

As before, the bracket 5 is attached to the surface material 31.
When the foam material is filled with the foam material 5, the foam material shrinks, and the surface material 31 other than the surface material 31 with which the bracket 55 abuts becomes “sink”, so that the surface material 31 has irregularities. You.

In order to solve this, in this embodiment,
As shown in FIG. 3, between the surface material 31 and the bracket 55 so that the bracket 55 does not contact the surface material 31.
At least a gap δ2 larger than the margin δ1 between the rising portions 51A, 53A and the engaging portion 33A, for example, about 5 mm
Gap δ2 is formed, and the gap δ2 has the gap δ
The cushion material 61 is provided so as to fill the space 2.

A cushioning member 63 (FIG. 3) is interposed between the surface member 31 and the parting member 33 on the front A side of the roof 27, and the cushioning member 63 has an amount corresponding to the margin δ1. Even if the surface material 31 is pushed down,
The surface material 31 can be automatically pushed up to a predetermined position. The cushion material 61 may be attached to the back surface of the surface material 31 or on the bracket 55, and the cushion material 63 may be attached to the back surface of the surface material 31 or the parting material 33.
May be stuck on the upper surface of the.

Next, the operation will be described. In this embodiment, when manufacturing the roof 27, first, the surface material 31, the parting material 33, the top plate 34, and the back plate 36 are assembled.

In this case, as shown in FIG. 3, since the rising portions 51A, 53A and the engaging portion 33A are locked, the surface material 31 is raised as shown by the dashed line.
It is once pushed down in the direction of the arrow X by a dimension larger than the allowance δ1 between A and the engaging portion 33A. In this case,
At the front A portion of the roof 27 and the portion where the bracket 55 is provided, the cushion members 61 and 63 are temporarily compressed and pushed down, and the rising portions 51A and 53A and the engaging portions 33A are pressed.
Is locked, the surface material 31 is accurately pushed back to a predetermined position by the restoring force of the cushion materials 61 and 63.

Thereafter, the surface material 31 is displaced in the direction of arrow Y to lock the rising portions 51A, 53A and the engaging portion 33A. Then, the rising portions 51A, 53A are swaged in the direction of arrow Z to form a surface. The member 31 is attached to the parting member 33.

Next, the surface member 31, the top plate 34, the back plate 36 and the like are fixed to each other via a plurality of rivets 44. When fixing via the rivets 44,
The mutual alignment of the rivet holes is important. For that purpose, it is important that the surface material 31 is accurately pushed back to a predetermined position by the restoring force of the cushion materials 61 and 63. Further, the space 38 is filled with a foam material through the injection port 100. During the injection of the foam material, gas is vented through the gas vent 103.

In this embodiment, since the bracket 55 does not abut on the surface material 31, when the foam material is filled, even if the foam material shrinks, “sink” occurs uniformly over the entire surface material 31. However, unlike the related art, only the portion where the bracket 55 abuts does not become high, and no irregularities are formed on the surface material 31.

In order to prevent the bracket 55 from abutting on the surface material 31, a space is provided between the surface material 31 and the bracket 55.
At least a gap δ2 larger than a margin δ1 between the rising portions 51A, 53A and the engaging portion 33A is formed. Since the cushioning material 63 is provided between the material 33 and the rising portions 51A, 53A and the engaging portion 33A, the surface material 31 is pushed down in the arrow X direction as shown by the dashed line in FIG. Even if it is locked by the cushion material 6
By the action of 1, 63, the surface material 31 is automatically pushed up to a predetermined position.

Accordingly, it is easy to align the rivet holes of the surface material 31, the top plate 34, the back plate 36, and the like, and the plurality of rivets 44 allow the members to be easily and easily connected with each other. Can be riveted accurately.

In the conventional one-way roof structure, the connection between the hanging part of the surface material and the parting material is made by riveting. In this embodiment, the surface material 31 is raised as shown by a dashed line in FIG. Parts 51A, 53A and engaging part 33
After being once pushed down in the direction of the arrow X by a dimension larger than the hook margin δ1 with A, the rising portions 51A and 53A are displaced in the direction of the arrow Y to lock the rising portions 51A and 53A with the engaging portions 33A. , 53A are attached to the parting material 33 by caulking in the direction of arrow Z, so that riveting work is not required, and the appearance of the design is improved.

Next, another embodiment will be described with reference to FIG. When manufacturing a roof 27 having a single-flow structure,
After locking the rising portions 51A, 53A and the engaging portion 33A, the surface material 31 needs to be completely pushed up to a predetermined position. If the surface material 31 is not completely pushed up, it is difficult to align the rivet holes of the surface material 31, the top plate 34, the back plate 36, and the like.

However, in the case of the roof 27 having the one-way structure, even if the surface material 31 is automatically pushed up to a predetermined position by the action of the cushion materials 61 and 63, FIG.
As shown in the figure, there is a case where the vertical portion W of the hanging portion 51 on the side surface B is not sufficiently pushed up in a portion on the side of the skeleton. This is because the cushion material is not interposed in the portion. If a cushioning material is interposed in this portion, a cushioning material having a considerably large restoring force is required. Therefore, the adoption of such a cushioning material is not practical and is very difficult.

In this embodiment, no cushioning material is employed, and a fixing means (fixing tool) is provided between the side 65 near the skeleton side of the hanging portion 51 on the side surface B of the surface material 31 and the parting material 33. This means is constituted by, for example, a rivet 67 or the like, and is provided with holes 68, 6 formed at predetermined positions.
9 through the rivet 67. According to this, the surface material 31 is fixed to a predetermined position of the parting material 33.

FIG. 4 shows the structure of a roof 127 having a triangular shape according to another embodiment. In FIG. 4, the same components as those in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted.

The surface material 131 of the roof 127 has only the side surface A, is bent at the side surface A, and the side surface A is integrally formed with a hanging portion 151 that hangs substantially vertically.
A rising portion (not shown) is formed in the hanging portion 151, and the rising portion corresponds to the engaging portion 13 of the parting material 133.
Locked to 3A.

In this embodiment, two roofs 127
Three brackets 155 are provided.
A gap δ larger than the margin δ1 between at least the rising portion and the engaging portion 133A is provided between the surface material 131 and the bracket 155 so that the surface material 5 does not contact the surface material 131.
2, for example, a gap δ2 of about 5 mm is formed, and a cushion material (not shown) is provided in the gap δ2 so as to fill the gap δ2. In addition, a cushion material (not shown) is interposed between the surface material 131 and the parting material 133 at the front end C of the roof 127, and the surface material 131 is pushed down by the amount of the margin δ1. Also, the surface member 131 can be automatically pushed up to a predetermined position. According to this, so-called “sink” can be prevented in the triangular roof 127.

In addition, even with the roof 127, it is possible to employ the fixing means (fixing tool) in the portion on the side of the skeleton where the vertical width W of the hanging portion 151 on the side surface A is large. Almost the same effects can be obtained.

[0045]

According to the first aspect of the present invention, since the bracket does not come into contact with the surface material, when the foam material is filled, even if the foam material shrinks, "sink" is substantially uniform over the entire surface material. Therefore, unlike the related art, only the portion where the bracket abuts does not become high, and no irregularities are formed on the surface material.

[0046]

According to the second aspect of the present invention, the fixing member is provided between the part close to the skeleton side of the hanging portion of the surface material and the parting material. According to this, since the surface material is reliably pushed up to the predetermined position, the work of riveting the surface material to the back plate or the like becomes easy, and a roof having a high precision dimension is manufactured.
