Description

This disclosure relates to building materials.

Fittings used in the entrances of buildings are known (see, for example, Patent Document 1). An airtight material is stored in an airtight material receiving groove formed in the lower frame of the frame that houses the entrance door body, ensuring the airtightness of the door body.

JP 2010-121417 A

In the conventional building fixtures described in the publication, the opening of the airtight material receiving groove faces outdoors, and this shape had to be formed in the lower frame. For example, it is possible to configure the airtight material receiving groove so that the opening faces upward, but in this case, the airtight material would be visible from above, compromising the design.

The purpose of this disclosure is to provide a fitting with improved design, in which the opening of the airtight material receiving groove in which the airtight material is stored opens upward.

This disclosure relates to a fixture with an entrance door, comprising a frame body with a lower frame that is placed on the outdoor side of the entrance floor material, a door body that is placed within the frame body so that it can be opened and closed, a sealing member that is placed on the lower frame so that it can abut against the door body, and a cover member that is attached to the lower frame and covers at least the upper surface of the lower frame.

As shown in Figure 20, the crank fitting 213 has a rectangular plate-shaped base 213a with the center of the upper long side cut out, and a rectangular tip plate 213b that extends away from one side of the plate base 213a and bends at its end parallel to the plate base 213a. The plate base 213a, which is one end of the crank fitting 213, is positioned and fixed to the upper surface of the indoor side Y2 of the upper frame hollow frame portion 211a (see Figure 6, etc.), which has a reinforcing backing plate installed inside. The tip plate 213b, which is the other end of the crank fitting 213, is embedded in the mortar 813 while being fixed to an anchor 214 embedded in the upper structure 811 of the upper structure 81.

As shown in Figure 6, a seal packing 212a is attached to the door stop portion 212 facing the peripheral edge of the door body 3 via a metal cover material 212b and a resin extrusion 212c. The resin extrusion 212c is positioned at an offset position to avoid the crank fitting 213 and anchor 214, and as shown in Figure 6, has two hollow portions 2121c at the top and bottom, and the seal packing 212a is fixed to the bottom of the resin extrusion 212c. The upper end surface of the interior side Y2 of the door body 3 abuts against the seal packing 212a attached to the door stop portion 212 when the door body 3 is in the closed position.

The metal cover material 212b has two hollow sections 2121b at the top and bottom, and the upper and lower ends of the metal cover material 212b have outward extensions 2122b that extend to the outside of the room. The outward extension 2122b at the lower end of the metal cover material 212b covers the portion of the resin extruded section 212c at the center of the frame body 2, i.e., the lower end of the resin extruded section 212c. This hides the resin extruded section 212c from view of people passing through the opening in the building fixture 1. The underside of the metal cover material 212b is powder coated.

As shown in Figure 1, a concealed door closer 215 is located midway along the length of the upper frame 21. The concealed door closer 215 has a mechanism that closes the door body 3 slowly and smoothly at a safe speed.

As shown in Figure 6, the concealed door closer 215 has a closer body 215a that is placed inside the upper frame 21, and a connection part 215b that connects the closer body 215a to the door body 3. In this embodiment, the closer body 215a is placed inside the upper frame 21, resulting in a sleek appearance.

As shown in Figure 6, a decorative material 216 is provided on the outdoor side Y1 surface of the upper frame 21. The decorative material 216 extends from the lower end of the outdoor side Y1 surface of the upper frame 21, past the upper end of the upper frame 21, to the ceiling. The decorative material 216 extending from the upper frame 21 to the ceiling comprises an upper frame outdoor side decorative material 217 and an upper wall component decorative material 218.

The upper frame exterior decorative material 217 is arranged from the lower end to the upper end of the exterior Y1 surface of the upper frame 21. The upper wall component decorative material 218 is formed continuously with the upper frame exterior decorative material 217 and extends from the upper end of the upper frame exterior decorative material 217 (the upper end of the upper frame 21) to the ceiling. The upper wall component decorative material 218 is arranged on the exterior Y1 side of the upper structure 81 and forms the surface material of the upper wall 13 (see Figure 6) formed on the exterior Y1 side of the upper structure 81. The upper wall 13 is a wall provided at the top of the building fixture 1 and is arranged between the upper frame 21 and the ceiling.

The upper frame exterior decorative material 217 and the upper wall component decorative material 218 are integrally formed from the same decorative material 216. Because they are made of decorative materials with at least one of the same material, surface treatment, and paint, the exterior Y1 surfaces of the upper frame exterior decorative material 217 and the upper wall component decorative material 218 have the same type of exterior design and are unified. Furthermore, the surface of the upper frame exterior decorative material 217 provided on the exterior Y1 side of the upper frame 21 and the surface of the upper wall component decorative material 218 provided on the upper wall 13 located at the top of the building fixture 1 are located on the same plane.

As shown in Figure 7, the lower frame 22 is fixed to the floor structure 82. The lower frame 22 has a lower frame main body frame portion 221 that is L-shaped in cross section and a crank fitting 223. The lower frame main body frame portion 221 is L-shaped in cross section, with the outdoor side Y1 and upper side open, to correspond to the stepped lower structure 821. The lower part of the tip of the outdoor side Y1 forms a hollow box-shaped portion 221c. A base side plate portion 223a of a crank fitting 223, which has the same shape as the crank fitting 213, is fixed to the side surface of the indoor side Y2 of the box-shaped portion 221c. A tip side plate portion 223b of the crank fitting 223 is fixed to an anchor 825 embedded in the lower structure 821.

The lower frame main body frame portion 221 has a raised piece 221a formed at the end on the indoor side Y2. A seal packing 221b is attached to the raised piece 221a. When the door body 3 is in the closed position, the seal packing 221b attached to the raised piece 221a comes into contact with the lower end surface of the indoor side Y2 of the door body 3.

A cover member 222 is provided on the lower frame 22. As shown in Figure 21, the cover member 222 is made of a so-called black stainless steel plate member that has an oxide coating on its surface and is bent into an L shape when viewed from the side, and has a horizontally positioned portion 222a and a vertically positioned portion 222b. As shown in Figure 7, the horizontally positioned portion 222a extends to the outside of the room from the portion that is integrally connected to the vertically positioned portion 222b, and is folded downward above the seal packing 221b and then folded back toward the inside of the room. Therefore, the cover member 222 covers the upper surface of the seal packing 221b.

The folded-back front portion is adhered and fixed to the upper surface of the rising piece 221a of the lower frame 22 with double-sided tape 222c (see Figure 21). The vertically positioned portion 222b extends downward from the portion that is integrally connected to the horizontally positioned portion 222a, and as shown in Figure 7, is adhered and fixed to the two upper and lower side walls of the rising piece 221a of the lower frame 22 with double-sided tape 222c (see Figure 21). In this way, the cover member 222 covers the rising piece 221a of the lower frame 22.

As shown in Figure 22, the sleeve fixing bracket 225 comprises a plate-shaped fixed base 225a fixed to the upper surface of the lower frame 22, a guide plate 225b bent upward in an L-shape from the fixed base 225a, and a plate-shaped fixed portion 225c bent in an L-shape in the forward direction at the end of the guide plate 225b facing the vertical frame 23, and fixed to the portion of the sleeve 4 facing the leading end of the door body 3 when the door body 3 is in the closed position. The upper frame 21 is also provided with a sleeve fixing bracket 219, as shown in Figure 4, etc., which has a fixed base 219a, guide plate 219b, and fixed portion 219c of the same shape as the sleeve fixing bracket 225. The sleeve 4 is fixed to the sleeve fixing bracket 219 and sleeve fixing bracket 225.

As shown in Figures 5A and 5B, the vertical frames 23, 24 are fixed to the side structure 83. The vertical frames 23, 24 have vertical frame main body frame portions 231, 241 and door stop portions 232, 242 fixed to the inside of the vertical frame main body frame portions 231, 241 in the left-right direction on the indoor side Y2.

As shown in Figures 5A and 5B, the vertical frame main body frame portion 231, 341 has a vertical frame hollow portion 231a, 341a formed with a hollow structure having a square cross section, and vertical frame extension plates 231b, 341b extending from the outer left-right ends of the vertical frame hollow portion 231a, 341a toward the interior side Y2. As shown in Figure 4, sealing materials 231c, 241c are provided between the vertical frame extension plates 231b, 341b and the side structure 831 of the side structure 83.

The indoor side Y2 portions of the vertical frames 23, 24 are fixed to crank fittings 233, 243, which have the same shape as the crank fitting 213. The base side plate portions of the crank fittings 233, 243 are positioned and fixed to the indoor side Y2 surfaces of the vertical frame hollow frame portions 231a, 341a. The tip side plate portions of the crank fittings 233, 243 are embedded in the mortar 833 while being fixed to anchors 234, 244 embedded in the side structures 831 of the side structures 83.

As shown in Figure 5B, a seal packing 232a is attached to the door stop portion 232. When the door body 3 is in the closed position, the seal packing 232a attached to the door stop portion 232 abuts the outer surface of the end of the door body 3 on the indoor side Y2 in the left-right direction. Also, as shown in Figure 5A, a seal packing 242a is attached to the door stop portion 242. The seal packing 242a attached to the door stop portion 242 abuts the outer surface of the end of the sleeve portion 4 on the indoor side Y2 in the left-right direction.

As shown in Figure 5B, a seal packing 232a is attached to the door stop portion 232 facing the peripheral edge of the door body 3 via a metal cover material 232b and a resin extrusion 232c. As shown in Figure 5B, the resin extrusion 232c has two hollow portions 2321c on the left and right, and the seal packing 232a is fixed to the portion of the resin extrusion 232c inside the frame 2 (to the right in Figure 5B).

As shown in Figure 5B, the metal cover material 232b has two hollow portions 2321b on the left and right, and the inner and outer ends of the metal cover material 232b relative to the frame body 2 have outward extension portions 2322c extending to the outside, similar to the metal cover material 212b. The outward extension portion 2322c at the right end of the metal cover material 232b shown in Figure 5B covers the portion of the resin extruded member 232c at the center of the frame body 2, i.e., the right end of the resin extruded member 232c shown in Figure 5B, thereby hiding the resin extruded member 232c from view of people passing through the opening 80 of the building fixture 1. The right surface of the metal cover material 232b is powder coated.

As shown in Figure 5A, a seal packing 242a is attached to the door stop portion 242 facing the peripheral edge of the door body 3 via a metal cover material 242b and a resin extrusion 242c. As shown in Figure 5A, the resin extrusion 242c has two hollow portions 2421c on the left and right, and the seal packing 242a is fixed to the portion of the resin extrusion 242c inside the frame 2 (to the left in Figure 5A). The metal cover material 242b has two hollow portions 2421b on the top and bottom.

As shown in Figures 5A and 5B, decorative materials 236, 246 are provided on the outdoor side Y1 surfaces of the vertical frames 23, 24. The decorative materials 236, 246 extend from the inside in the left-right direction of the outdoor side Y1 surfaces of the vertical frames 23, 24 to the outside in the left-right direction, and extend further outward beyond the outer left-right ends of the vertical frames 23, 24. The decorative materials 236, 246 extending outward in the left-right direction from the vertical frames 23, 24 comprise vertical frame outdoor side decorative materials 237, 247 and panel body constituent decorative materials 238, 248 (decorative material 141).

The exterior vertical frame decorative material 237 of the hanging-side vertical frame 23 is positioned from inside the inner left-right edge of the exterior Y1 face of the hanging-side vertical frame 23 to the outer left-right edge. The exterior vertical frame decorative material 247 of the door-end vertical frame 24 is positioned from the inner left-right edge to the outer left-right edge of the exterior Y1 face of the vertical frame 24.

The panel body structural design materials 238, 248 (design material 141) are formed continuously with the vertical frame exterior design materials 237, 247, and extend outward in the left-right direction from the outer left-right ends of the vertical frame exterior design materials 237, 247 (the left-right ends of the vertical frames 23, 24). As shown in Figures 5A and 5B, the panel body structural design materials 238, 248 (design material 141) are positioned on the outdoor side Y1 of the panel body 14 on the outdoor side Y1 of the side structure 83, and form the surface material of the panel body 14 formed on the outdoor side Y1 of the side structure 83. The side wall portion 12 and the panel body 14 are wall portions provided adjacent to the sides of the building fixture 1.

The vertical frame exterior decorative materials 237, 247 and the panel body decorative materials 238, 248 (decorative material 141) are integrally formed from the same decorative materials 236, 246. Because they are composed of decorative materials with at least one of the same material, surface treatment, and paint, the exterior Y1 surfaces of the vertical frame exterior decorative materials 237, 247 and the panel body decorative materials 238, 248 (decorative material 141) have the same type of exterior design and are unified. Furthermore, the surfaces of the vertical frame exterior decorative materials 237, 247 attached to the exterior Y1 sides of the vertical frames 23, 24 and the surfaces of the panel body decorative materials 238, 248 (decorative material 141) attached to the panel body 14 positioned on the left-right outside of the building fixture 1 are located on the same plane.

The door body 3 is installed in a so-called outward-opening position, which means that it can rotate from a closed position toward the outside Y1. As shown in Figure 5B, the door body 3 is a swing door that can be opened and closed by rotating around the rotation axis of a hinge 25 attached to the vertical frame 23 on the hanging side.

The hinge 25 rotatably supports the door body 3 on the hanging side of the door body 3. One end of the hinge 25 is attached to the end face 33 on the hanging side of the door body 3 in the left-right direction, and the other end is attached to the surface of the hanging-side vertical frame 23 on the door body 3 side. The hanging-side end face 33 on the left-right direction of the door body 3 is a visible surface formed at the end of the hanging side of the door body 3 in the left-right direction, facing outward in the left-right direction. The visible surface that constitutes the hanging-side end face 33 of the door body 3 extends in the depth direction (prospective direction).

As shown in Figures 1, 2, and 9, the door body 3 is formed in the shape of a generally rectangular plate that is long in the vertical direction. An exterior handle 27 is provided on the surface of the exterior side Y1 of the door body 3. An interior handle 28 is provided on the surface of the interior side Y2 of the door body 3. The exterior handle 27 and the interior handle 28 function as opening and closing operation parts that can be grasped by a user who opens or closes the door body 3. The user can grasp the exterior handle 27 or the interior handle 28 and push or pull the door body 3 to open or close it.

As shown in Figure 3, a decorative material 31 is provided on the surface of the exterior side Y1 of the door body 3. The decorative material 31 provided on the surface of the exterior side Y1 of the door body 3 is arranged to extend in the left-right and up-down directions. As shown in Figure 5B, the decorative material 31 provided on the surface of the exterior side Y1 of the door body 3 has an extension portion 31a formed on the end side of the hanging point in the left-right direction that extends outward in the left-right direction of the door body 3 so as to cover the hinge 25. As a result, the hinge 25 is covered by the extension portion 31a, making it difficult to see the hinge 25 when viewed from the exterior side Y1.

The decorative material 31 on the exterior Y1 surface of the door body 3 and the decorative materials 236, 246 on the exterior Y1 surfaces of the hanging vertical frame 23 and the leading vertical frame 24 are made of at least one of the same material, surface treatment, and paint, so the exterior Y1 surfaces of the door body 3, hanging vertical frame 23, and leading vertical frame 24 have a unified appearance design of the same type. The surface of the decorative material 31 on the exterior Y1 surface of the door body 3 and the surfaces of the decorative materials 236, 246 on the exterior Y1 surfaces of the hanging vertical frame 23 and leading vertical frame 24 are located on the same plane.

Furthermore, as shown in Figure 6, the decorative material 31 provided on the exterior side Y1 surface of the door body 3 and the decorative material 216 provided on the exterior side Y1 surface of the upper frame 21 are made of decorative materials having at least one of the same material, the same surface treatment, and the same paint, so that the exterior side Y1 surfaces of the door body 3 and the upper frame 21 are unified with the same type of external design. The surface of the decorative material 31 provided on the exterior side Y1 surface of the door body 3 and the surface of the decorative material 216 provided on the exterior side Y1 surface of the upper frame 21 are located on the same plane.

In addition, a decorative material 32 is provided on the surface of the indoor side Y2 of the door body 3. The decorative material 32 provided on the surface of the indoor side Y2 of the door body 3 extends in the left-right and up-down directions. The decorative material 32 provided on the surface of the indoor side Y2 of the door body 3 and the decorative material 31 provided on the surface of the outdoor side Y1 of the door body 3 are composed of decorative materials having at least one of the same material, the same surface treatment, and the same paint, so that the outdoor side Y1 and indoor side Y2 surfaces of the door body 3 are unified with the same type of exterior design.

As shown in Figure 6 and other figures, the exterior side portion of the top end surface of the door body 3 has a convex portion 301 that protrudes upward relative to the interior side portion. The convex portion 301 protrudes upward from the hanging side of the exterior side portion of the top end surface of the door body 3 to the door tip side. A corner resin member 35 is fixed to the convex portion 301. The corner resin member 35 is fixed to the corner formed by the connection between the upper end surface of the convex portion 301 of the door body 3 and the exterior side surface so as to cover the corner, and this portion constitutes a resin core material 352 with insulating properties. As shown in Figure 6, the resin core material 352 is made of hard resin that is L-shaped in cross section.

A water-stopping material 351, made of a softer resin than the resin core 352 and extending upward, is combined and integrated with the resin core 352 at the indoor end of the resin core 352, i.e., the portion of the resin core 352 located above the indoor end of the convex portion 301. As shown in Figure 6, the water-stopping material 351 slopes upward toward the outdoor side, i.e., it slopes upward toward the outdoor side Y1, which is the left side of Figure 6. This sloped configuration prevents rainwater from seeping indoors beyond the location where the water-stopping material 351 is provided.

A recessed groove, or concave groove 302, is formed in the interior-facing portion of the upper end surface of the door body 3, in the center between the hinge side and the door edge side. The groove-forming member 36 and the connection part 215b that connects the closer body 215a of the concealed door closer 215 to the door body 3 are fixed in the recess 302. Because the connection part 215b is located in the recess 302, it is not necessary to position the connection part 215b on the upper frame 21 side, and the lower surface 21a of the upper frame 21 is configured as a flat surface. The groove-forming member 36 is formed in a rectangular parallelepiped shape that opens upward, and gaps 303 are formed at the two corners of the longitudinal ends of the groove-forming member 36, as shown in Figure 11.

Rainwater that has penetrated beyond the water-stopping material 351 and entered the interior of the room flows through the groove formed by the groove-forming member 36, as shown by the arrows in Figure 10, and flows downward through the gaps 303 at the two corners of the longitudinal ends of the groove-forming member 36, entering the interior of the door body 3, and then flows from the interior of the door body 3 downward to be drained. In other words, the door body 3 is formed with a drainage flow path that allows rainwater to be drained.

As shown in Figure 5A, the sleeve 4 is located within the frame 2 adjacent to the door edge of the door body 3 and is fixed to the upper frame 21, lower frame 22, and vertical frame 24 on the door edge side of the frame 2.

The groove 403 extends toward the leading edge of the sleeve portion 4 that faces the leading edge of the door body 3 (the left side of the sleeve portion 4 in Figure 24), and is blocked at the leading edge of the sleeve portion 4 by a side wall 431, which is a wall that constitutes the leading edge of the sleeve portion 4. As shown in FIG. 4, with the sleeve fixing bracket 225 inserted into the groove 403, the lower part of the side wall 431 of the sleeve portion 4 that faces the leading end of the door body 3 when the door body 3 is in the closed position is fixed to the sleeve fixing bracket 225 with a screw 2251 (see FIGS. 4 and 27). More specifically, the lower part of the side wall 431 of the sleeve portion 4 is sandwiched between the fixed portion 225c of the sleeve fixing bracket 225 and a screw fixing member 2252 (see FIG. 29) with a U-shaped cross section, and is fixed to the sleeve fixing bracket 225 with a screw 2251. In this way, the sleeve portion 4 is fixed to the upper frame 21 and lower frame 22 of the frame body 2.

The side wall 431 and screws 2191, 2251 are covered and concealed by a cover member 432 (see Figures 25, 27 to 30), which is a vertically long rectangular plate-shaped member fixed to the leading edge of the sleeve section 4. That is, as shown in Figure 27, when the cover member 432 is not fixed to the leading edge of the sleeve section 4, the screws 2191, 2251 are exposed, but when the cover member 432 is fixed to the leading edge of the sleeve section 4, the screws 2191, 2251 are covered and concealed by the cover member 432, as shown in Figure 28. The cover member 432 has a hook-shaped engaging portion 4321 (see Figure 29) on the hanging side of the sleeve section 4. Additionally, as shown in Figure 29, the side wall 431 of the sleeve section 4 is provided with a fixing member 433 having a locking portion 4331 on the leading edge side of the sleeve section 4. The locking portion 4331 of the fixing member 433 locks the locking portion 4321 of the cover member 432, thereby fixing the cover member 432 to the leading edge end of the sleeve section 4.

As shown in Figure 8, a hollow core material 405 extending in the vertical direction is fixed to the portion of the sleeve portion 4 on the side of the vertical frame 24 of the frame body 2, i.e., the end of the sleeve portion 4 facing the vertical frame 24 in the left-right direction along the visible surface of the sleeve portion 4. The internal space 406 of the hollow core material 405 extends from the upper end to the lower end of the sleeve portion 4.

As shown in Figure 15, a wall fixing member 144 is fixed to the upper end of the panel body 14. The lower part is hollow and the upper part is open upward. The wall fixing member 144 is provided at the upper end of the panel body 14, extending from the left end to the right end in the left-right direction along the visible surface.

As shown in Figures 31 and 32, the fixed member 144 is fixed to the side wall 12 by fixing brackets 161 and 171, each bent into an L-shape. Specifically, fixing bracket 161 has a base 1611 and an extension 1612. Fixing bracket 171 has a base 1711 and an extension 1712. The base 1611 of fixing bracket 161 is fixed to the side surface of the wall fixed member 144 with a bolt. The base 1711 of fixing bracket 171 is fixed to the panel fixing portion 121 provided at the upper end of the side wall 12 with a bolt. The extension 1612 of fixing bracket 161 and the extension 1712 of fixing bracket 171 are then fixed with a bolt 1615, thereby fixing the panel body 14 in a suspended state to the side wall 12.

Connecting convex members 143 are provided on the lower frame members 1422 and vertical frame members 1423 of the panel body 14. As shown in Figures 14, 16, and 18, the connecting convex member 143 has a U-shaped fixed base 1431 and a connecting convex portion 1432 that protrudes from the center of the fixed base 1431 in the direction opposite the opening of the fixed base 1431. The lower frame member 1422 or the vertical frame member 1423 is inserted into the opening of the fixed base 1431, and the fixed base 1431 is fixed to the lower frame member 1422 or the vertical frame member 1423. The connecting convex portion 1432 is inserted into the groove of the connecting concave portion 1482, described below, with a clearance formed between the connecting convex portion 1432 and the connecting concave portion 1482, described below. Alternatively, as shown in FIG. 19, the fixed base 1431 is a rail 15 arranged below the panel body 14, which has a groove forming portion 151 at its top that forms a groove that opens upward and a hollow portion 152 at its bottom, and is inserted into the groove of the groove forming portion 151 with a clearance formed between the groove forming portion 151 and the connected protrusion 1432.

The vertical frame member 1424 has a connecting recess 148. As shown in Figures 17 and 18, the connecting recess 148 has a U-shaped fixed base 1481 and a connecting recess 1482 that protrudes from the center of the fixed base 1481 in the direction opposite the opening of the fixed base 1481.

The connecting protrusion 1432 is inserted into the groove of the connecting recess 1482, with a clearance formed between the connecting recess 1482 and the connecting protrusion 1432. This connects two adjacent panel bodies 14 together.

Next, the method for installing the fixture will be described. The method for installing the fixture described below is a method for installing the fixture 1 configured as described above, particularly for positioning the sleeve portion 4 on the frame body 2. In the sleeve portion installation method, the sleeve portion 4 is first positioned closer to the vertical frame 23 of the frame body 2, closer to the vertical frame 23 than the sleeve fixing bracket 219 of the upper frame 21 and the sleeve fixing bracket 225 of the lower frame 22. Next, the sleeve portion 4 is moved along the upper frame 21 and lower frame 22 toward the vertical frame 24, inserting the sleeve fixing bracket 219 of the upper frame 21 into the groove 401 and inserting the sleeve fixing bracket 225 of the lower frame 22 into the groove 403. Furthermore, as shown by the arrows in Figure 24, the sleeve portion 4 is moved along the upper frame 21 and lower frame 22 toward the vertical frame 24. At this time, the side surfaces of guide plate portion 219b and guide plate portion 225b form guide surfaces that guide sleeve portion 4 to fixed portion 219c and fixed portion 225c.

Next, the side wall 431 facing the sleeve fixing bracket 219 and sleeve fixing bracket 225, which is the leading edge portion of the sleeve section 4 that faces the leading edge of the door body 3 when the door body 3 is in the closed position, is abutted against the fixed portion 219c and fixed portion 225c, respectively, and the side wall 431 of the sleeve section 4 is fixed to the sleeve fixing bracket 219 and sleeve fixing bracket 225 with screws 2191 and 2251. Then, as shown by the arrow in Figure 25, a cover member 432 composed of a rectangular plate member that is long in the vertical direction is used to cover the side wall 431 and screws 2191 and 2251, and the cover member 432 is fixed to the leading edge end of the sleeve section 4. In addition, the outdoor cover material 41 and indoor cover material 42 of the sleeve section 4, which serve as cover members, are changed from the open state shown in Figure 26 to the closed state shown in Figure 1.

Next, we will explain the maintenance method for the electrical wiring in the sleeve section of the building fixture 1. The electrical wiring maintenance method described below is a maintenance method for replacing wiring made up of conductors electrically connected to the authentication device and electric locking device 6 when a malfunction occurs, such as the authentication device and electric locking device 6 installed in the sleeve section 4 not operating properly.

First, the sleeve portion 4 is removed from the frame body 2. In the above-mentioned fitting installation method, the sleeve portion 4 was installed on the frame body 2, but the sleeve portion 4 is removed from the frame body 2 by reversing the steps of that installation method.

That is, the outdoor cover material 41 and the indoor cover material 42 of the sleeve portion 4 are opened as shown in Figure 26, and the cover member 432 is removed to expose the screws 2191 and 2251 that secure the sleeve fixing brackets 219 and 225 to the side wall 431. Then, loosen and remove the screws 2191 and 2251, and move the sleeve portion 4 along the upper frame 21 and lower frame 22 toward the vertical frame 23. When the sleeve portion 4 has moved to a position closer to the vertical frame 23 than the sleeve fixing brackets 219 and 225, the sleeve portion 4 is removed from the frame body 2.

Next, the core material 405 is removed from the sleeve portion 4, and the conductor 44 that constitutes the wiring stored in the internal space 406 of the core material 405 is replaced. The core material 405 is then returned to the sleeve portion 4 and secured in place, and the steps in the construction method for the sleeve portion 4 of the fitting 1 described above are carried out to secure the sleeve portion 4 to the frame 2. This completes the maintenance method for the fitting.

Next, a method for installing the exterior wall panel will be described. The method for installing the exterior wall panel described below is a method for installing an exterior wall panel made up of the panel body 14 having the above-mentioned configuration.
First, fixing brackets 145 are fixed to the vertical frame members 1423, 1424, the upper frame member 1421, and the lower frame member 1422, and fixing brackets 146 are fixed to the upper frame member 1421, the lower frame member 1422, and the central frame member 1425. Fixing brackets 146 are also fixed to the vertical frame members 1423, 1424, and the horizontal frame member 1426, and fixing brackets 147 are fixed to the central frame member 1425 and the horizontal frame member 1426. Furthermore, sealant 1402 is applied to the peripheral edges of the vertical frame members 1423, 1424, the upper frame member 1421, the lower frame member 1422, the central frame member 1425, and the horizontal frame member 1426, and the decorative material 141 is fixed to the frame 142 with double-sided tape. In addition, the connecting protrusion member 143 and the connecting recess 148 are fixed to the frame 142, and the process of assembling the panel body 14 is carried out.

Next, the assembled panel body 14 is transported to the installation site. Next, the connected convex portion 1432 of the connecting convex member 143 at the lower end of the first frame 142 of the panel body 14 transported to the installation site is inserted into the groove of the groove forming portion 151 of the rail 15. The panel body 14 is then slid along the rail 15 to a predetermined position. The fixed member 144 of the panel body 14 is then fixed to the side wall portion 12 with the fixing brackets 161 and 171.

Next, the connected convex portion 1432 of the connecting convex member 143 at the lower end of the frame 142 of the second panel body 14 is inserted into the groove of the groove forming portion 151 of the rail 15. Then, the panel body 14 is moved along the rail 15 toward the first panel body 14, and the connected convex portion 1432 of the connecting convex member 143 of the vertical frame member 1423 of the second panel body 14 is inserted into the groove of the connected recess 1482 of the connecting recess 148 of the first panel body, thereby connecting them.

Next, the third, fourth, etc. panel bodies 14 are connected in the same way as the first and second panel bodies 14, completing the exterior wall panel installation method.

According to the present embodiment described above, the following effects are achieved.
In this embodiment, the building fixture 1 comprises a resin profile 212c arranged in the upper frame 21 and a pair of vertical frames 23, 24, which are opposite the peripheral edge of the door body 3 as the door body main body, and a metal cover material 212b covering the portion of the resin profile 212c on the central side of the frame body 2.

As a result, the inclusion of the resin profile 212c makes it possible to improve thermal insulation. Furthermore, the resin profile 212c can be covered and concealed so that it is not visible to people passing through the opening, improving the design. As a result, it is possible to achieve both improved thermal insulation and improved design.

In addition, in this embodiment, the fitting 1 is installed in an opening 80 in a side wall 12 made of reinforced concrete. This allows the fitting 1 installed in a side wall 12 made of reinforced concrete to have improved thermal insulation.

In addition, in this embodiment, the frame 2 is fixed to anchors 214, which serve as fixed parts, provided on the side wall 12 made of reinforced concrete. This makes it possible for the building fixture 1 to be fitted with reinforced concrete (RC).

In addition, in this embodiment, a crank fitting 213 is fixed to the frame body 2 as an anchor fixing member that is fixed to the fixed portion anchor 214. As a result, by fixing the crank fitting 213 to the anchor 214 in an offset positional relationship where the resin extrusion 212c avoids the crank fitting 213, the frame body 2 can be securely fixed to the reinforced concrete.

In addition, in this embodiment, the surface of the cover material 212b is powder coated. This makes it possible to perform powder coating, whereas resin cover members cannot be powder coated due to their low heat resistance.

In addition, in this embodiment, the panel body comprises an aluminum lattice-shaped frame 142 and decorative material 141 arranged on the outdoor side of the frame 142. With this configuration, the frame 142 is made of an aluminum lattice-shaped material, making it possible to reduce the weight of the panel body 14. Furthermore, the panel body 14, consisting of the lattice-shaped frame 142 and the decorative material 141 arranged thereon, can be assembled in a factory in advance and then transported to the construction site for construction, thereby reducing the amount of construction work required on site and improving workability.

In addition, in this embodiment, the upper part of the panel body is supported and suspended from above. This configuration makes it possible to ensure a clearance between the lower frame member 1422 and the rail 15. As a result, the clearance can absorb dimensional changes in the frame 142 due to temperature changes.

In addition, in this embodiment, insulation material 1401 is placed in the space surrounded by the frame and decorative material. This makes it possible to improve the thermal insulation of the panel body 14. The insulation material 1401 also makes it possible to suppress noise, etc., that would be generated if the thin decorative material were struck.

In addition, in this embodiment, sealing 1402 is applied between the decorative material 141 and the peripheral edges of the vertical frame members 1423, 1424, upper frame member 1421, lower frame member 1422, central frame member 1425, and horizontal frame member 1426 that make up the frame 142. This makes it possible to make the space between the frame 142 and the decorative material 141 watertight.

In addition, in this embodiment, the decorative material 141 is fixed to the frame 142 with double-sided tape. This makes it possible to simply and firmly fix the decorative material 141 to the frame 142.

In addition, in this embodiment, one of the left and right ends of the frame 142 is connected by being inserted into an adjacent frame 142, and the lower end of the frame 142 is connected by being inserted into the rail 15 located below the lower end of the frame 142. This makes it possible to ensure clearance between the lower frame member 1422 and the rail 15, as well as between the connected convex portion 1432 of the connecting convex member 143 and the connected concave portion 1482 of the connecting concave portion 148. In addition, the gap between the panel bodies 14, known as the clearance, can easily be made uniform, for example, to about 5 mm.

In addition, in this embodiment, the method for installing exterior wall panels includes the steps of transporting the assembled panel body 14, which has been assembled by fixing the decorative material 141 to the frame 142, to the installation site, inserting the lower end of the frame 142 of the panel body 14 transported to the installation site into the rail 15 arranged below the lower end of the frame 142 and sliding it to a predetermined position relative to the rail 15, and supporting the upper part of the panel body 14 in a suspended state at the predetermined position.
This eliminates the need to assemble the panel body 14 at the construction site, making it possible to improve workability at the construction site.

In addition, in this embodiment, the fitting 1 is equipped with a seal packing 221b as a sealing member arranged on the lower frame 22 so that it can abut against the door body 3 as the door body, and a cover member 222 attached to the lower frame 22 and covering at least the upper surface of the lower frame 22. This allows the cover member 222 to cover the upper surface of the lower frame 22, making it possible for people passing through the opening 80 to see the cover member 222 instead of the upper surface of the lower frame 22. This allows for improved design.

In addition, in this embodiment, the end of the outdoor-facing cover member 222 is folded back toward the indoor side. This makes it possible to prevent the cover member 222 from being damaged by being kicked by the feet of a person passing through the opening 80.

In addition, in this embodiment, the cover member 222 covers the upper surface of the seal packing 221b. This allows the seal packing 221b to be covered by the cover member 222, and makes it possible to hide the seal packing 221b with the cover member 222 so that it is not visible to people passing through the opening 80. This makes it possible to improve the design.

In addition, in this embodiment, the cover member 222 is fixed to the lower frame 22 using double-sided tape 222c. This makes it possible to simply and firmly fix the cover member 222 to the lower frame 22.

In addition, in this embodiment, the cover member 222 is made of stainless steel. This allows for a luxurious metallic feel and enhances the design.

In addition, in this embodiment, an oxide coating is formed on the surface of the cover member 222. This allows the oxide coating to exhibit a luxurious feel and enhances the design.

In addition, in this embodiment, the lower frame 22 is made of aluminum. This makes it possible to reduce the weight of the frame body 2 and improve the design of the lower frame 22.

In addition, in this embodiment, the upper frame 21 and lower frame 22 are provided with sleeve fixing brackets 219, 225 to which the sleeve portions 4 are fixed, and grooves 401, 403 are formed at the upper and lower ends of the sleeve portions 4 through which the sleeve fixing brackets 219, 225 can pass. This makes it possible to install the sleeve portions 4 by inserting the sleeve fixing brackets 219, 225 into the grooves 401, 403 to guide the sleeve portions 4.
