Description

  The present invention relates to a technique for filling a gap between an opening device such as a sash and a door and an outer wall material.

  Conventionally, between an opening device such as a sash (window) or door provided in an opening of a building and an outer wall member arranged so as to surround the opening device, water from a gap formed between the two is provided. In order to prevent the intrusion, a so-called wet joint method is known in which a sealing material configured as a semi-liquid joint material is filled in the gap.

  There is also known a dry joint method in which a packing material configured as a joint material formed in advance is inserted into a gap between the frame of the opening device and the outer wall material. In Patent Document 1, a dry joint method using a dry joint material such as a joint article is disclosed.

Japanese Patent No. 3958873

  Regarding the wet joint method, there is a concern that fading of the appearance design may be impaired because fading, adhesion of dirt, cracking, and the like may occur due to aging of the sealing material after construction. In addition, regarding weather resistance such as cracking, it is considered that the amount of ultraviolet irradiation to the sealing material greatly affects.

  On the other hand, with regard to the dry joint method, since the dry joint material is a prefabricated member produced at a factory or the like, it can be said that its weather resistance is easy to ensure higher than the sealing material filled at the construction site. . However, especially for the outer wall material to be installed around the opening, since the width dimension and the like are generally adjusted on-site by cutting, the gap formed between the cutting end and the opening device is The width is likely to vary, and a wide gap is formed at a certain portion, and a narrow gap is formed at a certain portion, and there is a concern that the appearance of the appearance design is impaired.

  Therefore, in view of the above problems, the present invention proposes a novel joint method for filling the gap between the opening device and the outer wall material.

  Furthermore, when a dry joint material is inserted into the gap in a situation where a wide gap or a narrow gap is formed, compression variation occurs depending on the location of the dry joint material, and it is difficult to ensure uniform water stoppage. Become. In particular, as shown in FIG. 14, when there is a step in the seam portion 93 of the outer wall materials 92 </ b> A and 92 </ b> B due to cutting processing, a pinhole (hole) is likely to be formed, and water intrusion from this portion is likely to occur. There are concerns about the occurrence.

  In addition, as shown in FIG. 14, most of the corner portions 91 of the opening device 90 are configured at right angles, but it is difficult to ensure water stoppage at the corner portions 91 as compared to other straight portions. Become. That is, when using a long dry joint material 94, it is necessary to bend and insert into the gap of the corner 91, or to abut the end portions 94a and 94b at the corner 91. There is a concern that pinholes (holes) may be formed at the locations. In addition, in patent document 1, although it discloses concretely about the application to the linear part in a vertical frame or a horizontal frame, it does not disclose the concrete structure about a corner | angular part.

  Moreover, since it is possible that the dry joint method will increase the number of parts used compared with the wet joint method, there is a concern that the construction management burden at the construction site will increase. Even if a construction manual is created, there is a concern that work may be done without following the procedure, or that parts may be forgotten to be attached, resulting in construction failures. . In addition, it takes time to create a construction manual, education and training.

It is preferable.

  Further, regarding the setting of the joint width of 5 mm shown in FIG. 4, in the case of a normal wet joint using the sealing material 50, the joint width is generally required to be 10 mm or more. However, in this embodiment, since the sealing material 50 is a reinforcing material after forming a dry joint by the intermediate base member 30, it is necessary to secure a joint width required in a general wet joint. Absent.

  Further, as shown in FIG. 5, the end portion 30A in the longitudinal direction of the intermediate portion base member 30 is configured to cover the portion of the connecting portion packing material P3 of the corner end portion base member 20A. A gap between the front surface of the corner end base member 20A (the surfaces 23a and 26a and the surface of the tongue piece 28a) and the back surface of the intermediate base member 30 is blocked by the connecting portion packing material P3. It is supposed to be. In order for the end portion 30A of the intermediate portion base member 30 to cover the portion of the connection portion packing material P3 of the corner end portion base member 20A without a gap, the connection portion packing material of the corner end portion base member 20A. It is preferable that the concavo-convex shape formed on the front side of P3 is a shape along the concavo-convex shape formed on the back side of the cross section of the intermediate base member 30 shown in FIG.

Next, the configuration of the base cover member 40 shown in FIGS. 5 and 6 will be described.
The base cover member 40 is attached to the portion of the corner end base member 20A from the upper side after the intermediate base member 30 is attached to the corner end base member 20A. Similarly to the corner end base member 20A, the base cover member 40 is configured in a substantially L shape in plan view by resin molding or the like. A packing material P41 for the back surface is pasted on the back side of the side portions 41a and 41b that form the L-shape and are orthogonal to each other. Engaging groove portions 42a and 42b penetrating in the vertical direction are formed in the end portions 46a and 46b of the side portions 41a and 41b so as to be cut in the longitudinal direction of the side portions 21a and 21b. The end portions of the frame side vertical wall portion 33 of the intermediate portion base member 30 can be inserted into the engagement groove portions 42a and 42b. The frame side vertical wall portion 33 is inserted into the engagement groove portions 42a and 42b. By inserting, the base cover member 40 can be positioned.

  Further, as shown in FIG. 6, the widths of the end portions 46a and 46b of the side portions 41a and 41b are formed between the frame side vertical wall portion 33 and the outer wall material side vertical wall portion 34 of the intermediate base member 30. When the base cover member 40 is further pushed in with the frame-side vertical wall portion 33 inserted into the engagement groove portions 42a and 42b, the end of the base cover member 40 is fitted. The portions 46a and 46b are fitted to the intermediate base members 30 and 30.

Further, rod-like convex portions 43a and 43b are projected. Further, boundary packing materials P6 and P6 are attached so as to surround the convex portions 43a and 43b, respectively. Further, the convex portions 43a and 43b and the boundary packing materials P6 and P6 can be arranged at the position of the boundary portion K of the frame side packing materials P2 and P4. In the state attached to the base member 20A, the boundary packing material P6 can be sandwiched between the frame side packing materials P2 and P4.

  As a result, as shown in FIG. 5, even when a gap is formed at the boundary K between the frame side packing materials P2 and P4, the gap can be filled with the boundary packing material P6. It becomes possible to reliably form a continuous series of packing materials without gaps by the materials P2, P4, and P6. In particular, since it is assumed that the length of the intermediate base member 30 is adjusted by cutting at the construction site, and it is assumed that the shape of the cut portion of the frame side packing material P4 is thereby varied, the boundary The sandwiching of the partial packing material P6 on the boundary portion K is effective in forming a continuous series of packing materials.

  Further, as shown in FIGS. 5 and 7, in the side portions 41a and 41b of the base cover member 40, on the side closer to the outer wall member 2A side than the engaging groove portions 42a and 42b, a vertical wall having a substantially L shape in plan view.

The boundary portion is covered from above.

  Further, as shown in FIG. 9, the corner decorative member 70 is a member in which one end 70 a in the longitudinal direction is cut out in an L shape and the other end 70 b is formed in a tip shape of an arrow. A groove portion 71 is formed to sandwich the engagement side portions 45a and 45b of the portion 45. One end side of the groove 71 is opened and the other end is closed. After the engagement sides 45a and 45b are inserted and slid from the open side of the groove 71, the engagement sides 45a and 45b are formed on the closed side. By abutting, the fitting of the corner decorative member 70 to the decorative member mounting portion 45 is completed. Then, in the state in which the corner decorative member 70 is fitted, the outer wall material 2A and the surface 72a of the corner decorative member 70 and the surface 62a of the plate surface portion 62 of the intermediate decorative member 60 are shown in FIG. A gap between 2B and 2C and the frame 10 of the opening device 1 is covered.

Next, the construction procedure using each member having the above configuration will be described in detail.
If it demonstrates sequentially from the upper left of FIG. 1, it will be in the state to which the frame 10 of the opening part apparatus 1 was first attached to the housing side which is not shown in figure. The frame 10 is configured in a square shape, and the corner end base members 20A and 20B are pressed against the corner portions 11A and 11B, respectively, and the corner end base members 20A and 20B are fixed to the housing side. Is done.

  Here, as shown in FIG. 10 (a), for fixing the corner end base member 20A in the corner 11A, first, the corner end base member 20A is moved with respect to the frame 10 of the opening device in the direction of the arrow F1. Then, the end of the outer wall back packing material P1 is temporarily peeled off, and the fixing tool 29b is temporarily fixed to the housing through the long hole 22b. Thereby, positioning of the corner | angular part edge part base member 20A in the arrow Y direction in a figure is performed.

  Further, as shown in FIG. 10B, the corner end base member 20A is pressed against the frame 10 in the direction of the arrow F2, the end of the outer wall back packing material P1 is temporarily peeled off, and the long hole 22a is formed. The fixing tool 29a is temporarily fixed to the housing side. The pressing of the corner end base member 20A in the direction of the arrow F2 here becomes possible when the fixture 29b temporarily fastened moves through the long hole 22b.

  Then, by fixing the fixing tool 29a completely, the corner end base member 20A is positioned and fixed in the direction of the arrow X in the figure, and finally the fixing tool 29b is completely fixed, so that the end of the corner part is fixed. Fastening of the base member 20A is completed. In addition, the site | part of the outer wall back packing material P1 peeled off temporarily is returned to the state affixed by the adhesive surface of the back surface.

  In addition, in the state where the corner end base member 20A is fastened, the frame-side packing material P2 is compressed, thereby ensuring the water stoppage between the frame 10 and the corner end base member 20A.
