Description

  The present invention relates to a fitting in which a face material is mounted in a frame body such as a curtain wall, a sash, and a shoji screen.

Conventionally, in a joinery in which a vertical member and a horizontal member are connected to form a frame, and the vertical member is attached to the vertical groove of the vertical member and the horizontal groove of the horizontal member is attached to the horizontal member. Since rainwater may enter the vertical and horizontal grooves, it is necessary to treat the rainwater that has entered the vertical and horizontal grooves.
A joinery has been proposed in which rainwater that has entered the vertical and horizontal grooves is drained from the horizontal grooves.
For example, as disclosed in Patent Document 1, the back-up material is embedded in the vertical groove of the vertical member, the sealing material is applied to the upper portion of the backup material, the vertical groove is closed, the water is stopped, and the vertical groove enters. There has been proposed a joinery in which rainwater flows from the seal portion to the lateral groove of the cross member and drains from the drain hole of the cross member.

In such a joinery, as described above, when the backup groove is embedded in the vertical groove of the vertical member and the sealing material is applied to the upper surface of the backup member so as to close the vertical groove, the ceiling is sealed in the pocket. Since the material is difficult to be applied, the pocket portion has insufficient water stoppage, and some rainwater that has entered the vertical groove may flow down from the pocket portion.
That is, the pocket has a cavity on the bottom surface side and an opening on the surface side, and the width of the opening is smaller than the width of the cavity, that is, a so-called dovetail shape. Is injected into the cavity, it is difficult for the sealing material to be applied to every corner of the cavity, so that the sealing material is not easily applied in the pocket.

  An object of the present invention is to provide a joinery that reliably shuts off the groove and allows rainwater that has entered the longitudinal groove to flow into the lateral groove even when the inner surface of the groove for attaching the face material has a pocket for attaching the airtight material. It is to be.

  The present invention relates to a frame member in which a longitudinal member having a longitudinal groove for attaching a face member and a transverse member having a transverse groove for attaching the face member are connected to each other so that the longitudinal groove and the transverse groove are continuous four times. The vertical groove and the horizontal groove are inserted and attached to the four continuous grooves, and an airtight material attaching pocket is provided on the inner surface of the vertical groove or the horizontal groove, and the airtight material attached to the pocket is in contact with the surface of the face material. Sealing and closing the groove having the pocket with the water stop means, so that rainwater entering the vertical groove flows into the horizontal groove, the water stop means is fitted into the groove An attached backup material; a seal material applied to a portion of the pocket facing the backup material; and a main seal material applied over an upper surface of the backup material and an inner surface of the groove, the backup material comprising: A main body in contact with the inner surface of the groove, and provided on the main body. And when the main body is fitted into the groove, at least one of the main body or the protrusion is elastically deformed, and when the main body is mounted in the groove, it is elastically restored into the pocket. It is a joinery characterized in that a protrusion enters.

In the present invention, the protrusion of the backup material can be formed of a foamed resin that can be elastically deformed.
In this way, when the protrusion is elastically restored and enters the pocket, a large amount of the sealing material can be expanded to fill the pocket without any gap.

In the present invention, the main body of the backup material has a resin portion or a metal portion harder than the protrusion, and the sheet-like sealing material that seals between the vertical member and the cross member is the hard resin portion or metal. Can be supported by part.
If it does in this way, since a sheet-like sealing material can be supported by the main part of a back-up material, the water stop property between a vertical material and a transverse material can be improved in a water stop means part.

In the present invention, the backup material is fitted and attached so as to sandwich the upper and lower surfaces of the inner member made of elastically deformable foamed resin having the projection and contacting the inner surface of the groove. And an outer member made of resin or metal harder than the inner member, and the outer member supports the sheet-like sealing material.
In this case, since the inner member is a foamed resin that can be elastically deformed, when the backup material is fitted into the groove, the inner member is also elastically deformed together with the protrusion, so that the backup material can be easily fitted into the groove.
Moreover, the hard resin part or metal part which supports a sheet-like sealing material can be comprised in an outer part, and the structure of a backup material can be simplified.

According to the present invention, the sealing material applied to the pocket can be expanded by the protrusion of the backup material, so that the water stoppage of the pocket portion can be improved.
Accordingly, even when the pocket for mounting the airtight material is provided on the inner surface of the groove for mounting the face material, it is possible to stop the groove and flow rainwater that has entered the vertical groove into the horizontal groove.

It has a lateral groove 5 for mounting material.
The vertical groove 4 and the horizontal groove 5 are continuous four times, and the four peripheral edges of the face material 6 are inserted into the vertical groove 4 and the horizontal groove 5 which are continuous four times, and sealed with a sealing material.
One of the vertical groove 4 and the horizontal groove 5 is closed by the water stop means 7 so that rainwater that has entered the vertical groove 4 flows into the horizontal groove 5.
For example, a portion below the bottom surface 5 a of the horizontal groove 5 in the vertical groove 4 is closed by the water stop means 7.
Rainwater that has flowed into the lateral groove 5 is drained from a drainage portion 8 formed in the lateral member 2.

  As shown in FIG. 2, the longitudinal groove 4 includes a first side surface 4 a that extends in an in-plane direction that is continuous with an inner surface 1 a in the in-plane direction of the longitudinal member 1, and an in-plane direction outer end of the first side surface 4 a. A bottom surface 4b extending in the out-of-plane direction, and an end in the out-of-plane direction of the bottom surface 4b and a second side surface 4c extending in the in-plane direction continuous to the inner side surface 1a. The cross-section is substantially U-shaped and opened on the inner side surface 1a, and a pocket 10 for attaching an airtight material (that is, a groove-shaped concave portion opened on one side in the out-of-plane direction) is continuous in the longitudinal direction on the first side surface 4a. Have. The first side surface 4a, the bottom surface 4b, and the second side surface 4c constitute the inner surface of the vertical groove 4.

The space between the second side surface 4 c of the vertical groove 4 and the other surface 6 b (for example, the outdoor side surface) of the face material 6 is sealed with a seal material 12.

As shown in FIGS. 3 and 4, the water stop means 7 includes a backup material 20 fitted in the longitudinal groove 4 and a seal material 30 applied to a portion of the pocket 10 facing the backup material 20. And a main sealing material 40 applied to the upper part of the backup material 20.
The backup material 20 has a main body 21 that fits in the longitudinal groove 4 and a protrusion 22 provided on the main body 21.
The main body 21 includes a first end surface portion 21a extending in an out-of-plane direction, a first side surface portion 21b extending in an in-plane direction continuous with the other end in the out-of-plane direction of the first end surface portion 21a, A second end surface portion 21c facing in the out-of-plane direction that is continuous with the inner end in the in-plane direction of the first side surface portion 21b, and one side end and the first end surface portion in the out-of-plane direction of the second end surface portion 21c. 21a is a block shape having a second side surface portion 21d that extends in the in-plane direction that continues one end in the out-of-plane direction, an upper surface portion 21e, and a lower surface portion. That is, the first end surface portion 21a and the second end surface portion 21c face each other in the in-plane direction, the first side surface portion 21b and the second side surface portion 21d face each other in the out-of-plane direction, and the upper surface portion 21e and the lower surface portion. Are facing vertically.

The protrusion 22 protrudes from the first side surface portion 21b of the main body 21 toward the other side in the out-of-plane direction from the first side surface portion 21b.
The protrusion 22 is elastically deformable, and the dimension in the in-plane direction of the protrusion 22 is smaller than the dimension in the in-plane direction of the opening 10a of the pocket 10, and the protrusion dimension of the protrusion 22 (dimension in the out-of-plane direction). Is smaller than the depth of the pocket 10, and the protrusion 22 is inserted from the opening 10a of the pocket 10 to the back 10b of the pocket 10.

When the backup material 20 is fitted into the vertical groove 4 and attached, the first end surface portion 21a, the first side surface portion 21b, and the second side surface portion 21d of the main body 21 are connected to the bottom surface 4b of the vertical groove 4, The second end surface portion 21c of the main body 21 is flush with the inner side surface 1a in the in-plane direction of the longitudinal member 1 while being in contact with the first side surface 4a and the second side surface 4c.
The protrusion 22 is inserted into the pocket 10 so as to be embedded in the sealing material 30 applied in the pocket 10, and the sealing material 30 applied in advance is expanded into the pocket 10. The water-tightness is improved by maintaining a full state without any gaps.

The main seal material 40 is applied to the upper surface portion 21e of the backup material 20 with a predetermined thickness so as to contact the bottom surface 4b of the vertical groove 4 and the first and second side surfaces 4a, 4c. The portion located at the same height as the bottom surface 5a is closed and water is stopped.
At this time, the main sealing material 40 is also applied in the pocket 10, but as described above, it is difficult to apply the main sealing material 40 in the pocket 10 without any gaps, and the pocket 10 is stopped by the main sealing material 40. There may be insufficient water.

As described above, even if the water sealing by the main sealing material 40 of the pocket 10 is insufficient, the lower portion of the pocket 10 where the main sealing material 40 is applied is stopped by the sealing material 30 as described above. Therefore, the water stoppage of the vertical groove 4 can be improved, and the rainwater that has entered the vertical groove 4 can flow through the horizontal groove 5 in its entirety.
As shown in FIG. 4, the cross member 2 has a shape having a lateral groove 5 by attaching a pressing edge 2 c to the cross member main body 2 b.

Next, the operation of stopping the vertical groove 4 with the water stop means 7 will be described.
As shown in FIG. 5 and FIG. 6A, a sealing material 30 is applied to the water stop portion in the pocket 10 of the vertical groove 4.
The sealing member 30 is a semi-liquid (gel) having adhesiveness and does not flow down even when applied to a part of the longitudinal pocket 10, but as shown in FIG. There is a gap between 10 and 10.

As shown in FIG. 6B, by pushing the backup material 20 into the vertical groove 4, the protrusion 22 is elastically deformed in contact with the first side surface 4a of the vertical groove 4 and moves along the first side surface 4a. To do. At this time, a portion continuous with the protrusion 22 of the main body 21 is elastically deformed.
Then, when the protrusion 22 is pushed into the pocket 10, the protrusion 22 is elastically restored and, as shown in FIG. 6C, the protrusion 22 enters the sealing material 30 so as to be embedded in the sealing material 30, and the sealing material. 30 is expanded to fill the pocket 10 with no gaps.

  Thereafter, as shown in FIG. 6 (d), the main sealing material 40 is placed on the upper surface 21e of the backup material 20, and a predetermined thickness is brought into contact with the bottom surface 4b of the longitudinal groove 4 and the first and second side surfaces 4a and 4c. By applying this, the vertical groove 4 is closed and water is stopped.

The backup material 20 will be described in detail.
As shown in FIGS. 3 and 5, the longitudinal member 1 and the transverse member 2 have a sheet-like sealing material (sealer) 50 on the inner side surface 1 a in the in-plane direction of the longitudinal member 1 and an end face 2 a in the longitudinal direction of the transverse member 2 a. In order to prevent rainwater from entering between the inner side surface 1a and the end surface 2a, they are connected to each other.
Since it is like this, it is preferable to seal between the water stop means 7 and the end surface 2 a in the longitudinal direction of the cross member 2 by supporting the sheet-like sealing material 50 with the backup material 20.

Therefore, the main body 21 of the backup material 20 is made of resin or metal harder than the protrusion 22 so that the sheet-like sealing material 50 can be supported, and the second end surface portion 21c is connected to the inner side surface 1a in the in-plane direction of the vertical frame. The protrusions 22 are made soft so that they can be elastically deformed.
For example, the backup material 20 is produced by two-color molding using the protrusion 22 as an elastically deformable foamed resin and the main body 21 as a resin harder than the protrusion 22.
As a result, the sheet-like sealing material 50 uniformly contacts over the inner side surface 1 a in the in-plane direction of the vertical frame 1 and the second end surface 21 c of the main body 21 of the backup material 20, and the sheet-like sealing material 50 is connected by the cross member 2. The pressing of the sealing material 50 can be supported by the bottom surface 4b of the vertical groove 4 with the main body 21 interposed.
In addition, you may produce the backup material 20 by 1 color molding by making the main body 21 and the processus | protrusion 22 into the foaming resin which can be elastically deformed.
Further, the base portion of the protrusion 22 (portion connected to the main body 21) is made of an elastically deformable resin (for example, foamed resin), and the tip side of the protrusion 22 is made of a resin or metal harder than the root portion. good.
The main body 21 may be made of a foam resin that can be elastically deformed, and the protrusion 22 may be made of a resin or metal harder than the main body 21. For example, the backup material 20 may be produced by two-color molding with the main body 21 made of an elastically deformable foamed resin and the protrusions 22 made of a resin harder than the main body 21.
In addition, the portion on the projection 22 side (the portion adjacent to the projection 22) in the main body 21 is made of an elastically deformable resin (for example, foamed resin), and the other portions in the main body 21 are harder than the portion on the projection 22 side. Resin or metal may be used.
That is, the backup material 20 has a portion where at least one of the main body 21 or the protrusion 22 is elastically deformed when the main body 21 is fitted in the vertical groove 4, and when the main body 21 is attached in the vertical groove 4. Any structure may be used as long as the elastically deformed portion is elastically restored and the protrusion 22 enters the pocket 10 when elastically restored.

A second embodiment of the backup material 20 will be described.
As shown in FIG. 7 and FIG. 8, the backup material 20 is formed by an inner member 23 having a protrusion 22 and an outer member 24 fitted and attached so as to sandwich the upper and lower surfaces of the inner member 23. The inner member 23 is made of an elastically deformable foamed resin, for example, an elastically deformable sponge, and the outer member 24 is made of a resin or metal harder than the inner member, for example, aluminum.

9, the inner member 23 is in contact with the bottom surface 4b of the longitudinal groove 4 and the first and second side surfaces 4a and 4c, and the projection 22 is placed in the pocket 10 to expand the sealing material 30 and seal it. The material 30 is filled in the pocket 10 without a gap.
The first end surface portion 24a in the in-plane direction of the outer member 24 is brought into contact with the step portion 4d of the first and second side surfaces 4a and 4c of the vertical groove 4 to support the in-plane direction force, and in the in-plane direction. The second end surface portion 24b is continuous with the inner surface 1a of the longitudinal member 1 in the in-plane direction.
The first end surface portion 24a in the in-plane direction of the outer member 24 is further protruded toward the bottom surface 4b side of the vertical groove 4, and the protruding portion abuts on the bottom surface 4b of the vertical groove 4 to force in the in-plane direction. May be supported.

Specifically, in the same manner as the main body 21 described above, the inner member 23 includes a first end surface portion 23a, a first side surface portion 23b, a second end surface portion 23c, a second side surface portion 23d, an upper surface portion 23e, and a lower surface portion. The protrusion 22 is integrally provided on the first side surface portion 23b.
The outer member 24 is formed in a U shape with an upper surface plate 25, a connecting plate 26, and a lower surface plate 27, and is fitted and attached so that the upper and lower surfaces of the inner member 23 are sandwiched between the upper surface plate 25 and the lower surface plate 27. The first end surface portion 23a and the first and second side surface portions 23b and 23d of the member 23 are exposed to the outside of the outer member 24 in plan view.
Then, the upper surface plate 25 and the lower surface plate 27 are brought into contact with the step portions 4d of the first and second side surfaces 4a and 4c of the vertical groove 4, and the connecting plate 26 is flush with the inner side surface 1a in the in-plane direction of the vertical member 1. And
Moreover, in the above-mentioned 2nd Embodiment, although the inner member 23 was produced as foaming resin which can be elastically deformed, it does not restrict to this.
For example, only the protrusion 22 of the inner member 23 is made of an elastically deformable resin (for example, foamed resin), and the other part of the inner member 23 (or only the part adjacent to the protrusion 22) is made of a harder resin than the protrusion 22 The inner member 2 may be produced by two-color molding.
Further, the base portion of the protrusion 22 may be made of an elastically deformable resin (for example, foamed resin), and the tip side of the protrusion 22 may be made of a resin (or metal) harder than the root portion.
That is, the inner member 23 has a portion where at least a part of the inner member 23 having the protrusion 22 is elastically deformed when the inner member 23 is fitted into the longitudinal groove 4, and the inner member 23 is placed in the longitudinal groove 4. When attached, the elastically deformed portion may be elastically restored, and the protrusion 22 may be inserted into the pocket 10 when elastically restored.

In the above-described embodiment, the pocket 10 is formed only on the first side surface 4a of the longitudinal groove 4, but the pocket 10 may be formed on each of the first side surface 4a and the second side surface 4b. In that case, the protrusions 22 may be provided also on the second side surface portions 21 d and 23 d of the backup material 20.
In the above-described embodiment, the frame 3 is configured by connecting the vertical member 1 and the upper and lower horizontal members 2 so as to be so-called vertical wins. However, the present invention is not limited to this, and the vertical member 1 and the upper and lower horizontal members 2 are configured. The frame 3 may be configured by connecting the material 2 so as to be a so-called lateral winning. At this time, the pocket 10 is formed on the side surface of the lateral groove 5, and the lateral groove 5 ( The portion facing the bottom surface of the vertical groove 4) may be closed by the water stop means 7 to stop the water.
In addition, although the protrusion 22 was put in the pocket 10 and the sealing material 30 was pushed and expanded, the sealing material 30 was filled in the pocket 10 without a gap, but this was applied with the sealing material 30 applied in the pocket 10. By expanding from the state by the area of the protrusion 22 (body volume), it means that most of the gap that originally existed between the sealing material 30 and the pocket 10 is closed (or completely closed). . Therefore, not only the state where the pocket 10 is completely (100%) filled without a gap but also the state described above is included. In the above-described embodiment, the protrusion 22 is made of an elastically deformable foamed resin. However, when the backup material 20 is pushed into the longitudinal groove 4, the protrusion 22 is elastically deformed while being compressed, and the protrusion 22 is in the pocket 10. When the back-up material 20 is pushed to a position facing, the compressed protrusion 22 is elastically restored while expanding, so that the sealing material 30 applied in the pocket 10 can be more widely spread. This makes it possible to close most of the gap that originally existed between the sealing material 30 and the pocket 10.
The protrusions 22 are not limited to foamed resin, but may be other elastically deformable unfoamed resin.
Further, the first end surface portion 24a in the in-plane direction of the outer member 24 is brought into contact with the step portion 4d of the first and second side surfaces 4a, 4c of the vertical groove 4 (or the bottom surface 4b of the vertical groove 4). However, since the position of the push-in direction when the backup material 20 is pushed into the vertical groove 4 can be regulated by this, when the backup material 20 is pushed into the vertical groove 4 and fitted, the pocket 10 and the protrusion 22 are just opposite to each other. The position can be regulated to Further, the second end surface portion 21c of the main body of the backup material 20 or the connecting plate 26 of the outer member 24 can be positioned so as to be flush with the inner side surface 1a in the in-plane direction of the vertical frame.
