Description

Joint structure and door and window of profile

The present invention relates to a joint structure and a door and window, and more particularly to a joint structure in which an end surface of one of the profiles is joined to a joint surface of the other profile, and a joint formed by joining the profiles by the joint structure. Doors and windows.

Conventionally, for example, a door and window in which a door sash is movably opened and closed in an open frame such as a double-slot sash window is known. The opening frame constituting such a door and window is constructed by combining an upper frame, a lower frame, and a pair of vertical frames into a peripheral frame. Further, the door sash constituting the door and window is configured such that a face material such as a glass plate is held in a frame in which an upper frame, a lower frame, and a pair of vertical frames are combined into a frame.

In such a door and window, a joint structure in which an end surface of an upper frame or a lower frame (hereinafter, the upper frame and the lower frame are collectively referred to as a horizontal frame) is joined to a joint surface of a vertical frame constituting the open frame via a sheet-like seal member is used. . With such a joint structure, it is possible to further improve the water repellency by deforming the seal by the end surface of the cross frame (for example, see Patent Document 1).

However, in the case of performing the work of arranging the opening frame in the opening portion of the building, it is considered that the lateral frame is separated from the joint surface of the vertical frame by the end face due to the transportation method when transporting the opening frame. The force is generated in the direction, or the lateral frame is biased in the direction in which the end surface is separated from the joint surface of the vertical frame due to a dimensional error or the like of the elements constituting the opening. Thus, if the lateral frame is displaced in the direction away from the vertical frame, a gap is formed between the end surface of the lateral frame and the seal. If such a gap is generated, the water stopping performance cannot be ensured, and rainwater or the like may be infiltrated.

Further, although the joint structure of the end surface of the horizontal frame and the joint surface of the vertical frame is described here, the same is true in the joint structure in which the seal is interposed between the end surface of the vertical frame and the joint surface of the horizontal frame. The problem, and not limited to the open frame, causes the same problem in the joint structure of the structural elements of the door sash.

The present invention has been made in view of the above circumstances, and it is an object of the invention to provide a joint structure and a door and window of a profile which can maintain a good water stopping performance even if an end surface of one of the profiles is displaced in a direction away from the joint surface of the other profile.

In order to achieve the above object, the joint structure of the profile of the present invention is such that the joint surface of the end surface of the first profile and the joint surface of the second profile are joined with a seal therebetween, the seal being at least The portion which is deformed by pressing a profile contains an expandable material made of a water-absorbent resin.

According to the invention, since the seal member contains the expansion material made of the water absorbent resin at least in the portion deformed by the first profile pressing, even if the end face of the first profile is displaced in the direction away from the joint face of the second profile, The gap is generated, and since the expansion material absorbs water that has penetrated into the gap to expand, it is possible to suppress water from passing through the gap and ensure the water stopping performance.

Further, in the joint structure of the above-described profile, the expansion material constitutes a surface of the seal that abuts against an end surface of the first profile.

According to the present invention, even if the end of the first profile is displaced in the direction away from the joint surface of the second profile to generate a gap, the expansion material constituting the surface of the seal abutting the end face of the first profile absorbs and penetrates into the The water in the gap expands, so that water can be suppressed from passing through the gap to ensure the water stopping performance.

Further, in the joint structure of the above-described profile, the expansion material is contained in the seal in a state of being mixed in the unvulcanized rubber, and abuts against the end surface of the first profile, and a part of the surface of the seal is broken. , And the boundary portion between the first profile and the first profile is exposed.

According to the present invention, since the expansion material is contained in the above-described sealing member in a state of being mixed in the unsulfurized rubber, it is not exposed in the normal state, whereby even if moisture or the like adheres before the sealing member is used for the joint structure, It is also possible to suppress expansion of the expansion material. Therefore, there is no possibility of hindering the formation of the joint structure due to expansion of the expansion material in the seal when the joint structure is formed. Further, a part of the surface of the sealing member abuts against the end surface of the first profile to be broken, thereby exposing the expansion material at a boundary portion with the first profile, so that even if the end face of the first profile faces away from the second The direction in which the joint surface of the profile is displaced causes a gap, and the expansion material constituting the surface of the seal that abuts against the end surface of the first profile absorbs water that has penetrated into the gap to expand, so that water can be suppressed from passing through the Clearance to ensure water stopping performance.

Further, in the joint structure of the above-described profile, the end face of the first profile is formed by cutting a cross-section formed of a metal material, a resin material, or an extruded material formed of a composite material of a metal and a resin.

According to the invention, since the end face of the first profile has a cross section, the end face has a plurality of sharp portions. Therefore, in the case where the first profile presses the seal, the end face of the first profile can damage the surface of the seal and be easily broken.

Further, in the joint structure of the above profile, the above seal has: a substrate; a rubber layer formed on the surface and the back surface of the substrate, formed of an unvulcanized rubber; and an intumescent layer formed on one surface of the rubber layer and mixed with an unsulfurized rubber Made.

According to the present invention, since the expansion material is mixed in the unvulcanized rubber in the expansion layer formed on the surface of one of the rubber layers, the expansion material is not exposed at the surface of the expansion layer under normal conditions, thereby even in the sealing member It is also possible to suppress expansion of the expansion material before the joint structure is used to adhere moisture or the like. Therefore, there is no possibility of hindering the formation of the joint structure due to expansion of the expansion material in the seal when the joint structure is formed. Further, since the intumescent layer is formed on the surface of the rubber layer, in the case of abutting against the end surface of the first profile, the expanded material in the intumescent layer is exposed at a boundary portion with the first profile even if the first profile is The end portion is displaced in a direction away from the joint surface of the second profile to create a gap, and the expansion material constituting the surface of the seal abutting the end surface of the first profile absorbs water that has penetrated into the gap to expand, thereby enabling expansion Water is prevented from passing through the gap to ensure water stopping performance.

Further, in the joint structure of the above-described profile, the seal member has an expansion layer formed by mixing an expansion material and an unsulfurized rubber, and a degassing layer formed adjacent to the expansion layer for releasing the A gas contained inside the expanded layer.

According to the present invention, water vapor or the like which is absorbed by the expansion material in the manufacturing process of the intumescent layer or the like can be released to the outside by the degassing layer.

Further, in the joint structure of the above-described profile, the degassing layer is a base material of the seal.

According to the present invention, water vapor or the like which is absorbed by the expansion material in the manufacturing process of the intumescent layer or the like can be released to the outside by the base material of the sealing member.

Further, in the joint structure of the above-described profiles, the above-mentioned base material is made of non-woven fabric or gauze.

The door and window according to the present invention includes an opening frame and a door sash that is movably opened and closed in the opening frame, and constitutes a first profile and a second profile of at least one of the opening frame and the door sash. The joined structure of the profiles is joined.

According to the present invention, even if the end of the first profile is displaced in the direction away from the joint surface of the second profile to generate a gap, since the expansion material expands by absorbing water penetrating into the gap, it is possible to suppress water from passing through the gap. Ensure water stopping performance.

According to the present invention, there is an effect that good water stopping performance can be ensured even if the end of one of the profiles is displaced in the direction away from the joint surface of the other profile.

As schematically shown in Fig. 3, the sealing member 30 has a sheet shape. In the sealing member 30, a rubber layer 32 containing an unsulfurized rubber such as butyl rubber is formed on the front surface and the back surface of a base material 31 made of, for example, a nonwoven fabric or gauze, and is further coated on the surface of one of the rubber layers 32. The material 33 is formed. Expanded material 33 is made of superabsorbent polymer (SAP: Super Absorbent Polymer) and has a function of absorbing a large amount of water and gelling to maintain the water. Such an expansion material 33 is applied to the surface of one of the rubber layers 32 to constitute one surface of the sealing material 30.

Further, as shown in FIG. 4, when the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13, 14 are combined into a peripheral frame, the left end surface 12a of the lower frame 12 and the lower side of the left vertical frame 13 are joined. The face 13a is joined by a seal 30. At this time, the seal 30 interposed between the left end surface 12a of the lower frame 12 and the joint surface 13a on the lower side of the left vertical frame 13 is compressed and deformed by being pressed by the lower frame 12. Further, between the right end surface 12b of the lower frame 12 and the joint surface 14a of the lower side 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 The seal member 30 interposed between the right end surface 11b and the upper joint surface 14b of the right vertical frame 14 also undergoes compression deformation.

In the case where the operation of arranging the opening frame 10 having the joint structure as described above in the main body opening 2 of the main body 1 is performed, if the lower frame 12 is caused by the transportation method at the time of transporting the open frame 10, The left end surface 12a is disengaged from the joint surface 13a of the lower side of the left vertical frame 13, or the lower frame 12 is separated from the left vertical frame 12a by the dimensional error of the elements constituting the main body opening 2 or the like. A force is generated in the direction of the joint surface 13a on the lower side of the third surface, and as shown in FIG. 5, the left end surface 12a of the lower frame 12 and the seal member 30 and the expansion material are formed. A gap is created between 33.

As shown in FIG. 6, when a gap is generated and water such as rainwater penetrates into the gap, the expansion material 33 absorbs the water and expands in the joint structure, whereby the water can be prevented from passing through the gap. As a result, Can ensure water stopping performance.

Since the physical surface treatment such as chemical surface treatment or polishing is performed, the left end surface 12a or the like has a plurality of sharp portions. Therefore, when the lower frame 12 or the like is pressed against the sealing member 30, the left end surface 12a of the lower frame 12 or the like may damage the surface of the sealing member 30 and be easily broken, whereby the surface expansion material 33 can be easily exposed. .

(Embodiment 2)

Fig. 7 is a perspective view showing a state in which a door and window of a joint structure of a profile according to a second embodiment of the present invention, that is, a door and window according to a second embodiment of the present invention, is viewed from the inside. The door and window exemplified here is called a double-slot sash window, and has two left and right door sashes 50 in the opening frame 40, and the two sashes 50 are opened and closed with respect to the opening frame 40 in the left-right direction.

The opening frame 40 is formed by combining the upper frame 41, the lower frame (first profile) 42, and the pair of right and left vertical frames 43, 44 into a peripheral frame, and forms a rectangular opening. The upper frame 41, the lower frame 42, and the pair of left and right vertical frames 43, 44 are, for example, extruded shapes of a metal material such as aluminum. In the above-described opening frame 40, the upper frame 41, the lower frame 42, and the pair of left and right vertical frames 43, 44 are attached to the main body opening 4 of the main body 3 such as a wall of a house so as to be along the opening edge portion thereof.

The door sash 50 is configured to hold the face material 55 inside a frame formed by combining the upper frame 51, the lower frame 52, and the pair of right and left vertical frames 53, 54 into a surrounding frame. The upper frame 51, the lower frame 52, and the pair of left and right vertical frames 53, 54 are, for example, extruded shapes of a metal material such as aluminum.

As shown in Fig. 8, between the left end surface 42a of the lower frame 42 of the opening frame 40 constituting the door and window and the joint surface 43a of the lower side of the left vertical frame (second profile, hereinafter also referred to as the left vertical frame) 43 A seal 60 is interposed. Further, only the left end face 42a and the left side of the lower frame 42 are shown in the example of FIG. Between the joint faces 43a on the lower side of the vertical frame 43, however, in the above-described door and window, between the right end surface 42b of the lower frame 42 and the joint surface 44a on the lower side of the right vertical frame (hereinafter also referred to as the right vertical frame) 44 The same structure is also disposed between the left end surface 41a of the upper frame 41 and the upper joint surface 43b of the left vertical frame 43, and the upper end surface 41b of the upper frame 41 and the upper joint surface 44b of the right vertical frame 44. Seal 60.

Here, the left end surface 42a and the right end surface 42b of the lower frame 42 and the left end surface 41a and the right end surface 41b of the upper frame 41 are formed by cutting the extruded material of the metal material in a direction orthogonal to the longitudinal direction thereof. Cross-section. Further, it is preferable that the cross section is not subjected to a physical surface treatment such as chemical surface treatment such as alumite treatment or polishing.

As schematically shown in Fig. 9, the sealing member 60 has a sheet shape. In the sealing member 60, a rubber layer 62 containing a non-sulfurized rubber such as butyl rubber is formed on the front surface and the back surface of a substrate 61 made of, for example, a nonwoven fabric or a gauze, and laminated on the surface of one of the rubber layers 62. An intumescent layer 63 is formed by mixing the expansion material 64 with the unsulfurized rubber. The expansion material 64 is made of a highly water-absorptive resin and has a function of absorbing a large amount of water and gelling to retain the water.

In the sealing member 60, the ratio of the thickness of the intumescent layer 63 to the entire thickness is preferably 0.2 or more, more preferably 0.2 to 0.5. When the thickness of the intumescent layer 63 is 0.2 or more with respect to the entire thickness of the sealing material 60, when the sealing material 60 is pressed by the lower frame 42 to cause compression deformation, it can be included in The expansion material 64 in the intumescent layer 63 is exposed in a sufficient amount.

Such a seal 60 is manufactured in the following manner. First, as shown in Fig. 10(A), the unvulcanized rubber 65 for forming the rubber layer 62 is mixed together with the other components 66, and as shown in Fig. 10(B), the unformed layer 63 is formed. The vulcanized rubber 65 is mixed with an expansion material 64 made of SAP.

Next, as shown in FIG. 11(A), while the base material 61 such as a nonwoven fabric is conveyed between the pair of rollers 71 and 72, the unvulcanized rubber 65 is applied to one surface of the base material 61 to be mixed with the other components 66. The resulting material forms a rubber layer 62. After the rubber layer 62 is formed on one surface of the substrate 61, as shown in FIG. 11(B), the substrate 61 having the rubber layer 62 formed on one surface is transported between the pair of rollers 71 and 72. The other surface of the substrate 61 is coated with a material obtained by mixing the unsulfurized rubber 65 and the other component 66 to form the rubber layer 62. Thereby, the rubber layer 62 is formed on both surfaces of the base material 61.

Then, as shown in FIG. 11(C), the substrate 61 having the rubber layer 62 formed on both surfaces thereof is transported between the pair of rolls 71 and 72, and the unsulfurized rubber 65 is applied to the surface of one of the rubber layers 62. The expansion layer 63 is formed of a material mixed with the expansion material 64. Thus, the member in which the intumescent layer 63 is formed is cut into an appropriate size, thereby manufacturing the above-described sealing member 60.

In the seal 60 thus manufactured, since the expandable material 64 constituting the intumescent layer 63 is mixed in the unvulcanized rubber 65, it is not exposed on the surface.

Then, when the upper frame 41, the lower frame 42, and the pair of left and right vertical frames 43, 44 are combined into a peripheral frame, as shown in FIG. 12, the left end surface 42a of the lower frame 42 is interposed between the sealing member 60 and the left vertical frame 43. The lower joint surface 43a is joined. At this time, the seal 60 interposed between the left end surface 42a of the lower frame 42 and the joint surface 43a of the lower side of the left vertical frame 43 is compressed and deformed by being pressed by the lower frame 42. That is, the rubber layer 62 and the intumescent layer 63 are subjected to compression deformation. Further, between the right end surface 42b of the lower frame 42 and the lower joint surface 44a of the right vertical frame 44, between the left end surface 41a of the upper frame 41 and the upper joint surface 43b of the left vertical frame 43, and the upper frame 41 The seal member 60 interposed between the right end surface 41b and the upper joint surface 44b of the right vertical frame 44 also undergoes compression deformation.

Thus, by causing the sealing member 60 to undergo compression deformation, a part of the surface of the sealing member 60 is broken, that is, a portion of the unvulcanized rubber 65 of the intumescent layer 63 is broken, whereby the expanded material 64 is on the surface of the deformed portion, that is, The boundary portion between the lower frames 42 is exposed.

In the case where the operation of arranging the opening frame 40 having the joint structure as described above in the main body opening 4 of the main body 3 is performed, if the lower frame 42 is caused by the transportation method for transporting the opening frame 40, The left end surface 42a is disengaged from the joint surface 43a of the lower side of the left vertical frame 43, or the lower frame 42 is separated from the left vertical frame 42a by the dimensional error of the elements constituting the main body opening 4 or the like. When a biasing force is generated in the direction of the lower joint surface 43a of 43, a gap is formed between the left end surface 42a of the lower frame 42 and the seal 60 as shown in FIG.

When a gap is generated and water such as rainwater penetrates into the gap, the exposed expansion material 64 absorbs the water and expands as shown in FIG. 14 , thereby suppressing the passage of the water through the gap. As a result, the water stopping performance can be ensured.

According to the joint structure of the second embodiment described above, even if a gap is formed between the left end surface 42a of the lower frame 42 and the seal 60 adhered to the joint surface 43a of the left vertical frame 43, the expansion layer 63 is constituted by the seal 60. The expansion material 64 absorbs water that has penetrated into the gap to expand, so that it is also possible to suppress water from passing through the gap to ensure the water stopping performance, whereby even the left end surface 42a of the lower frame 42 is away from the joint surface of the left vertical frame 43. The direction shift of 43a also ensures good water stopping performance.

In particular, since the expansion material 64 constituting the expansion layer 63 of the sealing member 60 is mixed in the unvulcanized rubber 65 and is not exposed at the surface under normal conditions, even before the sealing member 60 is used for the joint structure, The seal 60 is attached with moisture or the like, and the expansion of the expansion material 64 can also be suppressed. Therefore, there is no possibility that the expansion of the expansion material 64 in the sealing member 60 during the formation of the joint structure hinders the formation of the joint structure. Moreover, when the joint structure is formed, the expansion material 64 is compressed between the seal member 60 and the lower frame 42 Since the boundary portion is exposed, the water that has penetrated into the gap is absorbed and expanded as described above, and as a result, it is possible to suppress the water from passing through the gap and improve the water stopping performance. Thereby, good mountability of the sealing member 60 can be ensured, and good water stopping performance can be ensured.

Further, the left end surface 42a of the lower frame 42 or the like is a cross section formed by cutting the extruded material of the metal material in a direction orthogonal to the longitudinal direction thereof, and is not subjected to chemical treatment such as alumite treatment. Since the physical surface treatment such as surface treatment or polishing is performed, the left end surface 42a or the like has a plurality of sharp portions. Therefore, when the lower frame 42 or the like presses the sealing member 60, the left end surface 42a of the lower frame 42 or the like can damage the intumescent layer 63 constituting the surface of the sealing member 60, and can be easily broken, thereby making it easy to The expansion material 64 is exposed from the intumescent layer 63.

Although the preferred embodiment 1 and the second embodiment of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made.

In the second embodiment, the rubber layer 62 constituting the sealing material 60 is composed of the unvulcanized rubber 65. However, in the present invention, the rubber layer constituting the sealing material may be composed of, for example, a synthetic rubber material, as long as it is The material that elastically deforms when the first profile is pressed may be used. In this case, when the sealing member is pressed by the first profile to cause compression deformation, a part of the unvulcanized rubber of the intumescent layer is broken, and the expanded material is exposed at the boundary portion with the first profile, thereby ensuring goodness. Water stop performance.

In the second embodiment described above, the intumescent layer 63 containing the expansion material 64 forms one surface of the sealing member 60. However, in the present invention, the expansion material can be used when the sealing member is pressed by the first profile to cause compression deformation. The boundary portion with the first profile may be exposed, and the intumescent layer may not form the surface of the seal. That is, as shown in Fig. 15, the sealing member 80 may be in the form of a sheet, and a rubber layer 62 containing an unsulfurized rubber such as butyl rubber is formed on the surface and the back surface of the substrate 61 made of, for example, a nonwoven fabric or the like. An intumescent layer 63 in which an expansion material 64 and an unsulfurized rubber are mixed is formed on the surface of one of the rubber layers 62, and is formed on the surface of the intumescent layer 63 by coating or coating. There is a surface layer 81.

In the sealing member 80, the ratio of the thickness of the intumescent layer 63 to the entire thickness is preferably 0.2 or more, more preferably 0.2 to 0.5. When the thickness of the intumescent layer 63 is 0.2 or more with respect to the entire thickness of the sealing member 80, when the sealing member 80 is pressed by the first profile (the lower frame 42 or the like) to cause compression deformation, it can be contained in the intumescent layer 63. The expanded material 64 in the medium is exposed in a sufficient amount.

In the second embodiment, the intumescent layer 63 containing the expansion material 64 forms one surface of the sealing member 60. However, in the present invention, the expansion material can be used when the sealing member is pressed by the first profile to cause compression deformation. The boundary portion between the first profiles may be exposed, and the intumescent layer may not form the surface of the seal. In other words, as shown in Fig. 16, the sealing member 82 may be in the form of a sheet, laminated on the surface of the substrate 61 made of, for example, a nonwoven fabric or the like. An intumescent layer 63 in which an expansion material 64 and an unsulfurized rubber are mixed, and a rubber layer 62 containing an unsulfurized rubber such as butyl rubber is formed on the back surface of the substrate 61, and is further formed on the surface of the intumescent layer 63. An unsulfurized rubber rubber layer 62 containing butyl rubber or the like is laminated.

In the sealing member 82, the ratio of the thickness of the intumescent layer 63 to the entire thickness is also preferably 0.2 or more, more preferably 0.2 to 0.5. When the thickness of the intumescent layer 63 is 0.2 or more with respect to the entire thickness of the sealing member 82, when the sealing member 82 is pressed by the first profile (the lower frame 42 or the like) to cause compression deformation, it can be contained in the intumescent layer 63. The expanded material 64 in the medium is exposed in a sufficient amount.

In the second embodiment, the intumescent layer 63 containing the expansion material 64 forms one surface of the sealing member 60. However, in the present invention, the expansion material can be used when the sealing member is pressed by the first profile to cause compression deformation. The boundary portion between the first profiles may be exposed, and the intumescent layer may not form the surface of the seal. That is, as shown in FIG. 17, the sealing member 83 may be formed only of an intumescent layer in which the expansion material 64 and the unsulfurized rubber are mixed.

Further, in the present invention, the sealing member may have a structure as described below. That is, as shown in FIG. 18, the sealing member 84 may be in the form of a sheet, and the intumescent layer 63 in which the expansion material 64 and the unsulfurized rubber are mixed is laminated on the surface of the substrate 61 made of, for example, a nonwoven fabric or the like, and A rubber layer 62 containing an unsulfurized rubber such as butyl rubber is formed on the back surface of the substrate 61. In other words, the same is true in the example shown in Fig. 16, the intumescent layer 63 can be combined with the substrate 61 adjacent.

In the sealing member 84, the ratio of the thickness of the intumescent layer 63 to the entire thickness is also preferably 0.2 or more, more preferably 0.2 to 0.5. When the thickness of the intumescent layer 63 is 0.2 or more with respect to the entire thickness of the sealing member 84, when the sealing member 84 is pressed by the first profile (the lower frame 42 or the like) to cause compression deformation, it can be contained in the intumescent layer 63. The expanded material 64 in the medium is exposed in a sufficient amount.

According to such a configuration, the water vapor or the like absorbed by the expansion material 64 during the production of the expansion layer 63 can be released to the outside by the substrate 61. Therefore, it is possible to suppress the vaporization or the like absorbed by the expansion material 64 from being vaporized inside the sealing material 84 in, for example, a high temperature environment. Further, the case where the intumescent layer 63 is adjacent to the substrate 61 is described here, and in the present invention, as long as the intumescent layer 63 is adjacent to the degassing layer composed of, for example, a nonwoven fabric or the like, the intumescent layer 63 may not be combined with the base. The material 61 is adjacent.

In the second embodiment described above, as shown in Fig. 12, the intumescent layer 63 is cut in the case where the sealing member 60 is pressed by the left end surface 42a of the lower frame 42, but in the present invention, as shown in Fig. 19, In the region pressed by the lower frame 42, compression deformation occurs in a state in which the intumescent layer 63 remains. Thus, due to the compression deformation of the sealing member 60, a part of the surface of the sealing member 60 is broken, that is, a part of the unvulcanized rubber 65 of the intumescent layer 63 is broken, whereby the surface of the deformed material 64 on the deformed portion, that is, the lower frame The boundary between 42 is partially exposed.

In the case where the operation of arranging the opening frame 40 having the joint structure in the main body opening 4 of the main body 3 is performed, if the lower frame 42 is at its left end surface 42a due to the transportation method at the time of transporting the opening frame 40 The lower frame 42 is separated from the left vertical frame 43 by the force acting on the lower joint surface 43a of the left vertical frame 43 or the dimensional error of the elements constituting the main body opening 4 or the like. When a force acts in the direction of the side joint surface 43a, a gap is formed between the left end surface 42a of the lower frame 42 and the seal 60 as shown in FIG. As shown in FIG. 21, when a gap is generated and water such as rainwater penetrates into the gap, the exposed expansion material 64 absorbs the water and expands in the joint structure, thereby suppressing the passage of the water through the gap. As a result, the water stopping performance can be ensured.

In the second embodiment described above, as shown in Fig. 12, the intumescent layer 63 is cut in the case where the sealing member 60 is pressed by the left end surface 42a of the lower frame 42, and in the present invention, not only the intumescent layer 63 but also the substrate 61 is attached. It is also possible to produce a large compression deformation. Thus, due to the compression deformation of the sealing member 60, a part of the surface of the sealing member 60 is broken, that is, a part of the unvulcanized rubber 65 of the intumescent layer 63 is broken, whereby the surface of the deformed material 64 on the deformed portion, that is, the lower frame The boundary between 42 is partially exposed.

In the case where the operation of arranging the opening frame 40 having the joint structure in the main body opening 4 of the main body 3 is performed, if the opening frame is transported The lower frame 42 generates a force in a direction in which the left end surface 42a is separated from the joint surface 43a of the lower side of the left vertical frame 43 or a dimensional error due to the elements constituting the main body opening 4, for the reason of the transportation method at 40 o'clock. When the lower frame 42 is biased in the direction in which the left end surface 42a is disengaged from the joint surface 43a on the lower side of the left vertical frame 43, the left end surface 42a of the lower frame 42 and the seal 60 are formed as shown in FIG. A gap is created between them. As shown in FIG. 23, when a gap is generated and water such as rainwater penetrates into the gap, the exposed expansion material 64 absorbs the water and expands in the joint structure, whereby the water can be prevented from passing through the gap. As a result, the water stopping performance can be ensured.

In the case where not only the intumescent layer 63 but also the base material 61 is largely compressed and deformed as described above, the intumescent layer 63 largely enters the inside of the rubber layer 62 as being pressed by the lower frame 42, the lower frame 42 and the exposed expansion material 64. The overlap width is increased to improve the water stopping performance.

In the first embodiment and the second embodiment, the upper frame 11 and the like are extruded shapes of a metal material such as aluminum. However, in the present invention, the first profile such as the upper frame may be made of a resin material or a metal or a resin. An extruded profile formed from a composite material.
