The opening frame that constitutes such a joinery is configured by a four-round frame including an upper frame, a lower frame, and a pair of vertical frames. Moreover, the shoji which comprises the said fitting is comprised by hold | maintaining a face material like a glass plate on the coffin comprised by combining the upper eaves, the lower eaves, and a pair of vertical eaves four times.

  In such a joinery, the end face of the upper frame or the lower frame (hereinafter, the upper frame and the lower frame are also referred to as horizontal frames) is joined to the joint surface of the vertical frame constituting the opening frame via a sheet-like sealing material. I am letting. Such a sealing material is pressed against the end face of the horizontal frame to be deformed, thereby improving water stoppage (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 57-174681

  By the way, when performing the work of installing the opening frame in the opening of the building, a force acts in the direction in which the end surface of the opening frame separates from the joining surface of the vertical frame by the transport method when transporting the opening frame. It is conceivable that a force acts in the direction in which the end face of the horizontal frame separates from the joint surface of the vertical frame due to a dimensional error of an element constituting the opening. If the horizontal frame is displaced in the direction of separating from the vertical frame in this way, a gap may be generated between the end face of the horizontal frame and the sealing material. If such a gap is generated, the water stop performance cannot be ensured, and there is a risk of allowing rainwater or the like to enter.

  Here, the joining of the end face of the horizontal frame and the joining surface of the vertical frame has been described, but the same problem occurs when a sealing material is interposed between the end face of the vertical frame and the joining face of the horizontal frame. Needless to say, this is not limited to the opening frame, and the same problem may occur in joining the components of the shoji.

  In view of the above circumstances, the present invention provides a sealing material and fitting capable of providing good water stoppage performance even when the end face of one profile is displaced in a direction away from the joint surface of the other profile. The purpose is to provide.

In order to achieve the above object, the sealing material according to the present invention has a rubber layer made of an unvulcanized rubber member formed on the front and back surfaces of a sheet-like base material, and the end surface of the first profile and the second shape A sealing material interposed between the joining surfaces of the materials, wherein the base material contains a swelling material made of a water-absorbing resin, or is made of a water-absorbing resin on the front and back surfaces of a sheet-like core material The swelling material is applied , and is provided so as to be biased so as to be close to the side in contact with the end face of the first profile .

  According to this invention, since the rubber layer is made of an unvulcanized rubber member, the pressed portion of the rubber layer is easily deformed by being pressed by the first profile. The base material on which the rubber layer is formed on the front surface and the back surface contains a swelling material made of a water-absorbing resin, or a swelling material made of a water-absorbing resin is applied to the front and back surfaces of the sheet-like core material. Therefore, when a part of the rubber layer is deformed, the swelling material can be exposed. As a result, even if the end face of the first profile is displaced in the direction away from the joint surface of the second profile and a gap is generated, the swelling material absorbs the water entering the gap and expands. It is possible to prevent water from passing through and ensure water stopping performance.

  According to this invention, since the base material is provided so as to be close to the side in contact with the end face of the first profile, a part of the rubber layer is deformed by being pressed against the end face of the first profile. Thus, the swelling material constituting the substrate can be easily exposed.

In the sealing material according to the present invention, a rubber layer made of an unvulcanized rubber member is formed on the front and back surfaces of the sheet-like base material, and the end surface of the first shape member and the joining surface of the second shape member An intervening sealing material, wherein the base material contains a swelling material made of a water-absorbing resin, or a swelling material made of a water-absorbing resin is applied to the front and back surfaces of a sheet-like core material. are those made proximate metallic material, on the side in contact with the end surface of the small formed by cutting an extruded shape member made of a composite material of a resin material or a metal and a resin as an end face of the first profile It is characterized by being provided so as to be biased.

  According to this invention, since the end face of the first profile is a small edge, the end face has a number of sharp portions. Therefore, since the base material is provided so as to be close to the side in contact with the end face of the first shape member, a part of the rubber layer is easily damaged by being pressed against the end face of the first shape member. By doing so, the swelling material which comprises a base material can be expressed easily.

  Further, the present invention is characterized in that, in the sealing material, the swelling material is exposed by deforming a part of the rubber layer in contact with the end face of the first profile.

  According to the present invention, since the swelling material is expressed by deforming a part of the rubber layer in contact with the end face of the first shape member, the end face of the first shape member is joined to the second shape member. Even if a gap is formed by displacement in a direction away from the surface, the swelling material absorbs water that enters the gap and expands, so that the passage of water through the gap is suppressed and water stopping performance is ensured. be able to.

  In the sealing material according to the present invention, the rubber layer contains a swelling material made of a water-absorbing resin.

  According to this invention, when the rubber layer is deformed, the swelling material contained in the rubber layer can be exposed.

  Moreover, the present invention is characterized in that, in the above sealing material, the core material is composed of a nonwoven fabric or a cold koji.

  Exemplary embodiments of a sealing material and a joinery according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is an external view schematically showing a joinery to which a sealing material according to an embodiment of the present invention is applied, that is, a joinery according to an embodiment of the present invention as viewed from the indoor side. The joinery illustrated here is called a sliding window in which the opening frame 10 includes two left and right shojis 20 and the two shojis 20 are opened and closed in the left-right direction with respect to the opening frame 10.

  The opening frame 10 forms a rectangular opening formed by four-frames the upper frame 11, the lower frame (first shape member) 12, and the pair of left and right vertical frames 13 and 14. The upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13 and 14 are extruded shapes made of metal such as aluminum. Such an opening frame 10 follows the opening edge of the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13, 14 with respect to the housing opening 2 formed in the housing 1 such as a wall of a house. It is attached as follows.

  The shoji 20 is obtained by holding a face material 25 inside a scissors formed by assembling an upper scissors 21, a lower scissors 22, and a pair of left and right vertical scissors 23, 24, respectively. The upper rod 21, the lower rod 22, and the pair of left and right vertical rods 23, 24 are extruded shapes made of metal such as aluminum.

  By the way, between the left end surface 12a of the lower frame 12 which comprises the opening frame 10 of the said fitting, and the lower side joining surface 13a of the left side vertical frame (2nd shape material, hereafter also called the left vertical frame) 13 As shown in FIG. 2, a sealing material 30 is interposed. In the example of FIG. 2, only the space between the left end surface 12 a of the lower frame 12 and the lower joint surface 13 a of the left vertical frame 13 is shown, but in the joinery described above, the right end surface 12 b of the lower frame 12 and Between the lower joint surface 14a of the right vertical frame (hereinafter also referred to as right vertical frame) 14, between the left end surface 11a of the upper frame 11 and the upper joint surface 13b of the left vertical frame 13, and the upper frame 11 is also interposed between the right end surface 11b of 11 and the upper joint surface 14b of the right vertical frame 14.

  Here, the left end surface 12a and the right end surface 12b of the lower frame 12 and the left end surface 11a and the right end surface 11b of the upper frame 11 are formed by cutting an extruded shape of a metal material in a direction perpendicular to the longitudinal direction. Petite. Further, it is preferable that the fore edge is not subjected to chemical surface treatment such as anodizing or physical surface treatment such as sanding.

  The sealing material 30 has a sheet-like form as schematically shown in FIG. 3 and includes a base material 31 and a rubber layer 32.

  The base material 31 is in the form of a sheet and includes a core material 311 and a swelling material 312. The core material 311 is a sheet-like material made of, for example, a nonwoven fabric or a cold koji. The swelling material 312 is made of a super absorbent polymer (SAP) and has a function of absorbing and gelling a large amount of water and retaining the water. Such a swelling material 312 is provided so as to be entangled with fibers constituting the core material 311. That is, the base material 31 contains the swelling material 312 made of a highly water absorbent resin.

  The rubber layer 32 is formed on the front surface and the back surface of the base material 31, and is composed mainly of an unvulcanized rubber member such as butyl rubber. Here, the thickness of the rubber layer 32 is larger on the side in contact with the joint surface 13 a of the left vertical frame 13 than on the side in contact with the left end surface 12 a of the lower frame 12. That is, in the sealing material 30, the base material 31 is provided so as to be close to the side in contact with the lower frame 12.

  When the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13, 14 are quadrilaterally framed, as shown in FIG. 4, the left end surface 12 a of the lower frame 12 is inserted into the left vertical frame 13 via the sealing material 30. It joins to the lower joining surface 13a. At this time, the seal material 30 interposed between the left end surface 12a of the lower frame 12 and the lower joint surface 13a of the left vertical frame 13 is compressed and deformed by being pressed by the lower frame 12. And when the sealing material 30 compressively deforms, a part of rubber layer 32 deform | transforms and a part of base material 31 expose | expresses. That is, the core material 311 and the swelling material 312 that are constituent elements of the base material 31 are exposed. In addition, between the right end surface 12b of the lower frame 12 and the lower joint surface 14a of the right vertical frame 14, between the left end surface 11a of the upper frame 11 and the upper joint surface 13b of the left vertical frame 13, and the upper frame. The sealing material 30 interposed between the right end surface 11b of the eleventh and the upper joint surface 14b of the right vertical frame 14 is similarly compressed and deformed.

  When performing the operation of installing the opening frame 10 in the housing opening 2 of the housing 1, the left end surface 12 a of the lower frame 12 is located below the left vertical frame 13 by the transportation method during transportation of the opening frame 10. The left end surface 12a is joined to the lower frame 12 on the lower side of the left vertical frame 13 due to a force acting in a direction away from the joint surface 13a or due to a dimensional error of an element constituting the housing opening 2 or the like. If a force is applied in a direction away from the surface 13a, a gap may be generated between the left end surface 12a of the lower frame 12 and the sealing material 30, as shown in FIG.

  In this way, when a gap is formed and water such as rainwater enters the gap, in the sealing material 30, as shown in FIG. 6, the exposed swelling material 312 absorbs the water and expands. Therefore, it is possible to suppress the water from passing through the gap, and as a result, it is possible to ensure water stopping performance.

  According to the sealing material 30 according to the present embodiment as described above, there is a gap between the left end surface 12a of the lower frame 12 and the sealing material 30 attached to the joint surface 13a of the left vertical frame 13. In addition, since the swelling material 312 contained in the base material 31 absorbs the water entering the gap and expands, it is possible to suppress the passage of water through the gap and ensure the water stopping performance. Therefore, even if the left end surface 12a of the lower frame 12 is displaced in a direction away from the joint surface 13a of the left vertical frame 13, the water stop performance can be improved.

  In particular, according to the sealing material 30, since the base material 31 is provided so as to be close to the side in contact with the left end surface 12 a and the like of the lower frame 12, the rubber layer 32 is pressed by being pressed by the lower frame 12. The swelling material 312 contained in the base material 31 can be easily exposed by partly deforming.

  Further, the left end surface 12a of the lower frame 12 or the like is a small edge formed by cutting an extruded shape of a metal material in a direction perpendicular to the longitudinal direction thereof, and it is a chemical treatment such as alumite treatment or sanding. Therefore, the left end face 12a and the like have a number of sharp portions. Therefore, since the base material 31 is provided so as to be close to the side in contact with the left end surface 12a or the like of the lower frame 12, a part of the rubber layer 32 is pressed by being pressed against the left end surface 12a or the like of the lower frame 12. The swelling material 312 which comprises the base material 31 can be easily exposed by being damaged and deform | transforming easily.

  According to the sealing material 30, since the swelling material 312 is contained in the base material 31, it does not appear on the surface in a normal state. Therefore, even if moisture or the like adheres before the sealing material 30 is used for joining the lower frame 12 and the left vertical frame 13, the swelling material 312 can be prevented from expanding. Therefore, the handleability can be improved.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the embodiment described above, in the sealing material 30, the base material 31 is provided so as to be close to the side in contact with the lower frame 12 that is the first shape material. However, in the present invention, the base material is provided. The location is not particularly limited.
