  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 away from the vertical frame in this way, even if the sealing material is made of an elastic material, it takes several days to return to its original shape by its own restoring force. As a result, the shape is maintained without following the displacement of the horizontal frame, and as a result, a gap may be formed between the end surface 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.

  Note that, here, the joining structure between the end face of the horizontal frame and the joining face of the vertical frame has been described, but the same applies to the joining structure in which a sealing material is interposed between the end face of the vertical frame and the joining face of the horizontal frame. Needless to say, a problem arises, and not only the opening frame but also a similar problem may occur in the joining structure of the components of the shoji.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a shape joining structure and a fitting according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is an external view schematically showing a case where a joinery to which a shape joining structure according to an embodiment of the present invention is applied, that is, a joinery according to an embodiment of the present invention is 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.

  The sealing material 30 is a sheet-like material made of an elastic material such as a synthetic rubber material, and is affixed to the lower joint surface 13a of the left vertical frame 13. The sealing material 30 has a larger outer dimension than the left end surface 12 a of the lower frame 12.

  As shown in FIG. 3, a swelling material 40 is applied to the surface of the sealing material 30. The swelling material 40 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 40 is applied so as to cover the surface of the sealing material 30.

  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 and the swelling material 40 interposed between the left end surface 12a and the lower joint surface 13a of the left vertical frame 13 are compressed and deformed by being pressed by the lower frame 12. It becomes. 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. Similarly, the sealing material 30 and the swelling material 40 interposed between the right end surface 11b of 11 and the bonding surface 14b on the upper side of the right vertical frame 14 are also compressed and deformed.

  When performing the operation of installing the opening frame 10 having the above-described joining structure in the housing opening 2 of the housing 1, the left end surface 12 a is left to the lower frame 12 by the transportation method when the opening frame 10 is transported. The left end surface 12a of the lower frame 12 is set to the left vertical due to a force acting in a direction away from the lower joint surface 13a of the vertical frame 13, or due to a dimensional error of an element constituting the housing opening 2. When a force is applied in a direction away from the lower joint surface 13a of the frame 13, a gap is formed between the left end surface 12a of the lower frame 12 and the sealing material 30 and the swelling material 40 as shown in FIG. May occur.

  This will be described in detail. Both the sealing material 30 and the swelling material 40 are made of a resin material. In particular, since the sealing material 30 is made of an elastic material, the lower frame 12 is detached from the left vertical frame 13. In this case, it is possible to return to the original shape, that is, the initial shape by its own restoring force. However, when it is compressed and deformed by being pressed against the left end surface 12 a of the lower frame 12 for a long time, the sealing material 30 and the swelling material 40 are restored even if the lower frame 12 is displaced in a direction away from the left vertical frame 13. The original shape cannot be instantaneously restored by the force, and it may take several days or more to return to the original shape by the restoring force, or may not return to the original state. Therefore, the sealing material 30 and the swelling material 40 retain their shapes without following the displacement of the lower frame 12, and as a result, a gap is generated between the left end surface 12 a of the lower frame 12.

  When a gap is formed in this way and water such as rainwater enters the gap, the swelling structure 40 absorbs the water and expands as shown in FIG. Can be prevented from passing through the gap, and as a result, water stopping performance can be ensured.

  According to the joint structure according to the present embodiment as described above, even if a gap is generated 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. Since the swelling material 40 applied to the surface of the sealing material 30 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. Thereby, 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.

  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 above-described embodiment, the example in which the swelling material 40 is applied to the surface of the sealing material 30 has been described. However, in the present invention, as shown in FIG. 7, the sealing material 50 is a super absorbent resin (SAP: Super Absorbent). It may be one containing a swelling material 60 made of (polymer). That is, the sealing material 50 formed into a sheet shape by kneading the swelling material 60 having a function of absorbing a large amount of water to be gelled and retaining the water may be used.

  Even when such a sealing material 50 is used, 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. It is joined to the lower joint surface 13 a of the left vertical frame 13 through the sealing material 50. At this time, by being pressed by the lower frame 12, the sealing material 50 interposed between the left end surface 12a and the lower joint surface 13a of the left vertical frame 13 is compressed and deformed. 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. 11 and the sealing material 50 interposed between the right end surface 11b and the upper joint surface 14b of the right vertical frame 14 are similarly compressed and deformed.

  When performing the operation of installing the opening frame 10 having the above-described joint structure in the housing opening 2 of the housing 1, the left end surface 12 a of the lower frame 12 has the left vertical frame 13 with respect to the lower frame 12 according to the transportation method during transportation of the opening frame 10. The left end surface 12a of the left vertical frame 13 with respect to the lower frame 12 due to a force acting in a direction away from the lower joint surface 13a of the lower frame 12 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 lower joint surface 13a, a gap may be formed between the left end surface 12a of the lower frame 12 and the sealing material 50, as shown in FIG.

  When a gap is generated in this way and water such as rainwater enters the gap, the sealing structure 50 of the swelling material 60 contained in the sealing material 50 is used in the joining structure as shown in FIG. The swelling material 60 on the surface of the water absorbs the water and expands, so that the water can be prevented from passing through the gap, and as a result, the water stopping performance can be ensured.

  According to the joining structure having such a configuration, even if a gap is generated between the left end surface 12a of the lower frame 12 and the sealing material 50 affixed to the joining surface 13a of the left vertical frame 13, the sealing material 50 Since the contained swelling material 60 absorbs the water entering the gap and expands, it is possible to suppress the passage of water through the gap and ensure water stopping performance. Even if the left end surface 12a 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 the above-described embodiment and its modification, the lower frame 12 is illustrated as the first profile and the left vertical frame 13 is illustrated as the second profile. However, as described above, the present invention is directed to the lower frame 12 and the left frame. The present invention is not limited to the vertical frame 13 and can be applied to any structure as long as the end face of one elongated shape member and the joining surface of the other shape member are joined. That is, it may be a joint between the saddle members of the shoji 20.

  In the above-described embodiment, the swelling material 40 is applied to the surface of the sealing material 30. However, in the present invention, the swelling material is the end face of the first profile like the left end face 12a of the lower frame 12. You may apply | coat to.
