Description

  The present invention relates to a window frame structure for constituting a daylighting wall.

  There are various types of curtain walls, roofs, etc. that can be used for daylight that constitute the outer wall of the building. Their structure is that a plurality of vertical beams extending vertically and a plurality of horizontal beams extending horizontally are crossed in a lattice pattern, and are surrounded by the verticals and the voids. A lighting wall is formed by fitting a wall material made of a glass plate, a decorative panel or a synthetic resin into the opening.

  Conventionally, an opening for a daylighting wall is a joint material used as a cushioning material and a connecting material for a window frame structure that can be independently present as a set of window frame structures formed by vertical and invisible. Through the arrangement, a plurality of sets are continuously arranged in the vertical direction and the horizontal direction.

  In addition, a material having a different coefficient of thermal expansion is often used between the material of the window frame structure such as aluminum and the material of the support member (mainly the building frame) that supports the window frame structure. For this reason, stress is generated between the window frame structure and the support member that supports the window frame structure due to the difference in coefficient of thermal expansion, and various proposals for absorbing the stress have been made (for example, Patent Documents). 1).

  However, since it was necessary to form a joint with a large width between the window frame structure and the adjacent window frame structure, the ratio of the frame material of the window frame structure in the entire daylighting unit is increased, which contributes to the design of the daylighting unit. There was a bug that affected it.

  Also, due to the difference in coefficient of thermal expansion, stress is generated between the window frame structure and the support member that supports the window frame structure. Especially when the interval between the vertical beam and the horizontal beam is widened, the window frame structure is caused by such stress. There are problems such as distortion and deterioration of the combined state of the window frame structure and the support member.

  In addition, when a fragile member such as glass is used as a daylighting material for a large window frame structure, the daylighting material is prevented from being damaged by the deformation of the window frame and the building frame due to interlayer displacement. For this reason, the width of the window frame can be widened, but the ratio of the window frame to the daylighting wall is increased, which affects the design.

  Then, an object of this invention is to provide the window frame structure which can solve the malfunction mentioned above.

  Moreover, an object of this invention is to provide the window frame structure which improves the designability of a lighting part by making the part which connects the frame material of a window frame structure thin.

  In the window frame structure according to the present invention, the horizontal beam coupled to the housing has at least one fitting portion for directly fitting with the horizontal beam of another window frame continuously provided in the vertical direction of the window frame. Therefore, the ratio of the window frame to the daylighting wall surface can be reduced to improve the design.

  In the window frame structure according to the present invention, the vertical beam coupled to the housing has at least one coupling part for directly coupling to the vertical beam of another window frame continuously provided in the horizontal direction of the window frame. Therefore, the ratio of the window frame to the daylighting wall surface can be further reduced to improve the design.

  In the window frame structure according to the present invention, each of the vertical beam and / or the horizontal beam has a joint for absorbing stress generated between the window frame and the support member, and thus the window frame having a large opening. It became possible to construct the structure.

The joints 40, 42, 44, and 46 are disposed between the vertical and invisible lines that form the vertical beam or the horizontal beam. The window frame structure 1 can be a substantially square of 5 [m] squares, for example.

  Although not clearly shown in FIG. 2, the window frame structures 101 to 801 that form continuous openings with the window frame structure 1 also have the same structure as the window frame structure 1. For example, the window frame structure 101 has vertical 110, 112, 114, and 116 that are arranged in parallel in the up-down direction, invisible eyes 120, 122, 124, and 126 that are arranged in parallel in the left-right direction, and a joint 140. , 142, 144, and 146.

The joint 44 is disposed between the upper end of the vertical 14 and the lower end of 16, and the joint 46 is disposed between the right end of the eyeless 24 and the left end of 26.

  The joints 40, 42, 44 and 46 are configured to have a function of absorbing the expansion / contraction length when members constituting the window frame structure expand / contract due to a change in ambient temperature.

  In FIG. 2, the frame of the window frame structure is formed by using two vertical or invisible shapes having the same shape, but the vertical length or the invisible length of the members may be different. good. That is, the position of the joint can be arranged at an arbitrary position of the crosspiece. It is also possible to form a window frame structure by connecting two or more joints of three or more vertical or invisible eyes.

  The daylighting materials 30a to 30e are fitted into the openings formed by the window frame structure 1. Similarly, the daylighting materials 130a to 130e, which are not partly illustrated, are fitted in the opening formed by the window frame structure 101, and the part is not illustrated in the opening formed by the window frame structure 201. The daylighting materials 230a to 230e are fitted into the openings formed by the window frame structure 301, and the daylighting materials 330a to 330e, which are not denoted by reference numerals, are fitted into the openings, and the openings formed by the window frame structure 401 are partially Are not fitted in the daylighting materials 430a to 430e, and the openings formed by the window frame structure 501 are partially fitted with the daylighting materials 530a to 530e not shown in the figure and the window frame structure 601 is formed.

  As the daylighting material composed of a polycarbonate resin, a material provided with a functional layer such as weather resistance, antifouling property or scratch resistance on the surface of a base material made of polycarbonate resin can be used. The weathering layer can be formed, for example, by coextrusion of a resin excellent in weather resistance such as an acrylic resin or a polycarbonate resin with an ultraviolet absorber added thereto and a base material made of a polycarbonate resin. .

  FIG. 3 is a diagram illustrating an example of a combined state of the window frame structure 1 and some bars of the adjacent window frame structure and the daylighting materials 30 a to 30 e and the housing 68 of the building 3.

  The building 3 includes a foundation 70, housings 68 a and 68 c of the building 3 that are disposed vertically on the foundation 70, buildings 68 b and 68 d of the building 3 that are installed in a direction parallel to the foundation 70, and the foundation 70. Torso edges 72a and 72b, etc., which are installed in a parallel direction.

  The vertical frame 10 of the window frame structure 1 and the vertical frame 114 of the window frame structure 101 are coupled by a coupling portion 5 a formed between the vertical frame 10 and the vertical frame 114, and the vertical frame 12 of the window frame structure 1 The vertical frame 116 of the window frame structure 101 is coupled by a coupling portion 5b formed between the vertical frame 12 and the vertical wall 116, and the vertical frame 14 of the window frame structure 1 and the vertical frame 510 of the window frame structure 501 are connected to each other. Are connected by a connecting portion 5c formed between the vertical 14 and the vertical 510, and the vertical 16 of the window frame structure 1 and the vertical 512 of the window frame structure 501 are the vertical 16 and the vertical 512. Are coupled by a coupling portion 5d formed between them (see FIG. 2).

  The mesh 20 of the window frame structure 1 and the mesh 324 of the window frame structure 301 are fitted by a fitting portion 6a formed between the mesh 20 and the mesh 324, and the window frame structure 1 has no mesh. 22 and the mesh 326 of the window frame structure 301 are fitted by a fitting portion 6b formed between the mesh 22 and the mesh 326, so that the mesh 24 of the window frame structure 1 and the window frame structure 701 The vertical 720 is fitted by a fitting portion 6c formed between the blank 24 and the vertical 720, and the blank 26 of the window frame structure 1 and the vertical 722 of the window frame structure 701 are empty. It fits by the fitting part 6d formed between the eyes 26 and the vertical 722 (refer FIG. 2).

  In the left frame of the window frame structure 1, the vertical 10 is coupled to the vicinity of the housing 3 b of the building 3 by a coupling portion 7 a formed near the lower end of the vertical 10, and the coupling is formed near the upper end of the vertical 12. The vertical 12 is connected to the vicinity of the housing 3a of the building 3 by the portion 7b, and the right rail of the window frame structure 1 is connected to the lower portion of the vertical 14 by the connecting portion 7c formed on the right frame of the window frame structure 1c. The vertical 16 is connected to the vicinity of the housing 3 d of the building 3 by a connecting portion 7 d formed near the upper end of the vertical 16.

  The lower frame of the window frame structure 1 has a joint 20 formed in the vicinity of the frame 3b of the building 3 and a joint formed in the vicinity of the right end of the joint 22 by a joint 8a formed near the left end of the joint 20. The joint 22 is connected to the vicinity of the housing 3c of the building 3 by the portion 8b, and the top rail of the upper frame of the window frame structure 1 is formed from the joint 8c formed near the left end of the joint 24. The joint 6 is joined to the vicinity of the housing 3 d of the building 3 by the joint 8 d formed near the right end of the joint 26.

  As shown in FIG. 3, the window frame structure 1 is coupled to the housing 68 of the building 3 by coupling portions 7 a to 7 d and coupling portions 8 a to 8 d.

  Further, the daylighting materials 30 a to 30 e are directly supported not only by the window frame structure 1 but also by the building 3. That is, the daylighting materials 30a to 30e are respectively supported by the frame 68 of the building 3 at two locations of the trunk edges 72a and 72b. In addition, the number of the coupling | bond places for supporting the lighting materials 30a-30e can be made into an appropriate number in consideration of the magnitude | size, weight, intensity | strength, etc. of the lighting materials 30a-30e. For example, when a daylighting material made of polycarbonate having a length in the longitudinal direction of about 5600 mm, a length in the lateral direction of about 500 mm, and a width of about 40 mm is used, it is preferable that the number of joints be five.

  The body edges 72a and 72b and the daylighting materials 30a to 30e connected to the building 3 are fastened to the connecting members installed on the daylighting materials 30a to 30e and the body edges 72a and 72b with fastening members such as screws, bolts, and nuts. To be combined.

  By connecting the body edges 72a and 72b connected to the building 3 and the daylighting materials 30a to 30e, even when a member that is easily damaged such as glass is used as the daylighting material of the large window frame structure, the daylighting is caused by the interlayer displacement. The material can be prevented from being damaged. That is, when the trunk edges 72a and 72b and the daylighting materials 30a to 30e are coupled, when the interlayer displacement occurs, the daylighting materials 30a to 30e are inclined so as to follow the deformation of the housing 68 of the building 3. . Since the window frame 1 is also coupled to the housing 68 or the trunk edge 72 of the building 3, the window frame 1 is also deformed following the housing 68 of the building 3 due to the interlayer displacement. For this reason, since the lighting materials 30a-30e can follow the deformation | transformation of the window frame 1 by interlayer displacement, and the lighting material 30 does not contact the deformed window frame 1, the lighting materials 30a-30e are damaged. It is not. In order to prevent the lighting material from being damaged, it is preferable to use a lighting material made of synthetic resin.

  FIG. 4 is a diagram illustrating an example of a method of joining the daylighting materials 30b to 30d and the trunk edge 72a.

  The daylighting material 30b and the daylighting material 30c are connected by fitting the convex portion 30b1 of the daylighting material 30b and the concave portion 30c2 of the daylighting material 30c. Similarly, the daylighting material 30c and the daylighting material 30d are connected by fitting a convex portion 30c1 of the daylighting material 30c and a concave portion 30d2 of the daylighting material 30d. The coupling member 32a is attached to the fitting portion between the convex portion 30b1 of the daylighting material 30b and the concave portion 30c2 of the daylighting material 30c, and the coupling member 32b is the concave portion 30d2 of the convex portion 30c1 of the daylighting material 30c and the daylighting material 30d. Are attached to the daylighting materials 30b to 30d. By fastening the coupling members 32a and 32b and the trunk edge 72a with bolts 64d to 64k, the daylighting materials 30b to 30d are directly supported by the trunk edge 72a. Although not shown in FIG. 4, the connecting portion between the daylighting materials 30a and 30b and the connecting portion between the daylighting materials 30d and 30e are also coupled to the trunk edge 72a in the same manner. Moreover, the coupling | bonding of the lighting materials 30a-30e and the trunk edge 72b is also the same.

  In this way, the daylighting materials 30a to 30e are configured to be supported by the housing 68 of the building 3 by being coupled to the trunk edges 72a and 72b of the building 3. For this reason, unlike a window frame structure such as a glass window sash that is generally used, the window frame structure 1 loads the lighting materials 30a to 30e installed in the opening formed by the window frame structure 1. It is not necessary to have a supporting function. Therefore, the members constituting the window frame structure 1 do not need strength to support all the loads of the daylighting materials 30a to 30e.

  Hereinafter, the vertical and seamless structures and the coupling method will be described.

  FIG. 5 is a cross-sectional view taken along the line A-A ′ of FIG. 2.

  As shown in FIG. 5, the stand 10 of the window frame structure 1 and the stand 114 of the window frame structure 101 are connected using a back surface coupling member 80.

  The vertical 10 has a face portion 10a having a decorative surface, a coupling portion 10b formed in contact with one end portion of the surface portion 10a so as to be orthogonal to the surface portion 10a and having a hole 10e, and the surface portion 10a. It has the recessed part 10c formed in the edge part with which the part 10b is couple | bonded, and the fitting part 10d formed in the other edge part of the surface part 10a.

  The vertical 114 has a face portion 114a having a decorative surface, a coupling portion 114b formed in contact with one end of the surface portion 114a so as to be orthogonal to the surface portion 114a and having a hole 114f, and the surface portion 114a. A concave portion 114c formed at an end portion to which the portion 114b is coupled, a first fitting portion 114d formed at the other end portion of the surface portion 114a, and a second for fitting with the rear coupling member 80. And a fitting portion 114e.

  The back coupling member 80 includes a back surface portion 80a, a first fitting portion 80b formed so as to be in contact with one end portion of the back surface portion 80a and orthogonal to the back surface portion 80a, and the other end portion of the back surface portion 80a. A second fitting portion 80c formed so as to be perpendicular to the back surface portion 80a, and a third fitting portion 80d formed so as to be perpendicular to the back surface portion 80a from a substantially central portion of the back surface portion 80a. have.

  The verticals 10 and 114 are coupled to each other by a coupling portion 5a including a hole 10e formed in the vertical 10, a hole 114f formed in the vertical 114, and a screw 62a. Further, the vertical 114 and the back coupling member 80 are fitted by the second fitting part 114 e of the vertical 114 and the third fitting part 80 d of the back coupling member 80.

  The sealing material 52 is press-fitted into a U-shaped recess formed by the recess 10 c of the vertical 10 and the recess 114 c of the vertical 114.

  The stand 10 of the window frame structure 1 and the stand 114 of the window frame structure 101 are directly coupled by the screw 62a in the coupling portion 5a, and a joint is formed only by the sealing material 52. For this reason, compared with the normal window frame structure, the ratio which occupies for the whole lighting part of the frame material including a joint can be made small, and it became possible to improve the designability.

  In addition, although a sealing material can be used for the clamping member which clamps the lighting materials 30a and 130e, it is preferable to use a gasket. This is because when the gasket is used as the clamping member, the window frame structure and the daylighting material are not completely fixed, and the daylighting material is displaced, so that it is possible to follow the thermal expansion or thermal contraction of the daylighting material. .

  The coupling structure of the vertical frame 10 of the window frame structure 1, the vertical frame 114 of the window frame structure 101, and the back coupling member 80 has been described above with reference to FIG. 5. It should be noted that the other vertical structures 12, 14 and 16 of the window frame structure 1 and the connection structure of the other vertical window frame structures adjacent to each other have the same structure as the connection portion of the vertical structures 10 and 114. Have.

Moreover, it has the 2nd flange 81c formed in the lower end part of the flat plate 81a so as to be orthogonal to the flat plate 81a.

  The seamless 20 and the seamless 324 are formed by a fitting portion 6a configured by the second fitting portion 20b4 of the second member 20b of the seamless 20 and the first fitting portion 324b of the seamless 324. Are mated. Further, the second member 20b of the seamless 20 and the back coupling member 81 are formed of a hole 20b5 formed in the second member 20b of the seamless 20 and a first flange 81b of the first coupling 81 of the back coupling member 81.

Moreover, the lighting material 30b is also supported by the housing 68 of the building 3 as shown in FIG. For this reason, since it is not necessary to support the entire load of the daylighting material 30b, the seamless 20 can be made of aluminum or the like and can have a simple structure.

  The daylighting material 330b is sandwiched between the gasket 355a fitted to the second fitting portion 324c of the seamless 324 and the gasket 355b fitted to the third fitting portion 324e of the seamless 324.

  The sealing material 53 b is press-fitted into a gap formed in the vicinity of the second fitting portion 20 b 4 of the second member 20 b with the seamless 20 and the first fitting portion 324 b of the seamless 324.

  The joint 20 of the window frame structure 1 and the joint 324 of the window frame structure 301 are directly coupled by a fitting portion, and the joint for visually dividing the window frame structure 1 and the window frame structure 301 is only the sealing material 53b. It is formed. For this reason, compared with the normal window frame structure, the ratio which occupies for the whole lighting part of the frame material including a joint can be made small, and it became possible to improve the designability.

  When the daylighting material 330b expands due to thermal expansion and contraction, the thermally stretched portion is accommodated by the gap J formed between the lower surface of the first fitting portion 324b of the seamless 324 and the upper end of the daylighting plate 330b. be able to. For example, when a daylighting material having a longitudinal side length of about 5 m using a polycarbonate material is used, it is preferable that the thermal elongation of about 15 mm is accommodated.

  Moreover, although a sealing material can be used for the clamping member which clamps the lighting material 330b at a substantially upper end, it is preferable to use a gasket. This is because when the gasket is used as the holding member, the window frame structure and the daylighting material are not fixed, and the daylighting material is displaced, so that the thermal expansion or contraction of the daylighting material can be followed.

  Moreover, the fitting part (30c1 and 30d2 of FIG. 4) between the back side gaskets (55a of FIG. 6 etc.) fitted to the seamless 20, 20, 24, and 26 and the daylighting materials 30a to 30e. It is preferable to press-fit the sealing material in the vicinity of the intersection with the fitting portion, etc. This is because the watertightness of the window frame structure 1 can be further enhanced by press-fitting the sealing material into the portion.

  Further, by forming a drainage hole or slit in a part of the support portion 20b3 and the second fitting portion 20b4 of the second member 20b of the seamless 20, the rainwater that has entered the seamless 20 is made outside. It becomes possible to discharge.

It has the same structure as the part.

  A sealing material 52 is press-fitted into the gap formed at the joint between the vertical 10 of the window frame structure 1 and the vertical 114 of the window frame structure 101, and the window frame structure 1 and the window frame structure 101 are: It is divided in appearance and structure. Similarly, the other vertical wall is press-fitted with a sealing material between adjacent vertical walls, and is divided from the adjacent window frame structure in terms of appearance and structure. In addition, a seal material 53b is press-fitted into a gap formed in the vicinity of the fitting portion between the mesh 20 of the window frame structure 1 and the mesh 324 of the window frame structure 301, and the window frame structure 1 and the window frame The structure 301 is divided in appearance and structure. Similarly, the seals are press-fitted between the other blanks and the adjacent blanks, and are structurally divided from the adjacent window frame structure.

  As described above, in the window frame structure 1, it is possible to simplify the coupling structure with the adjacent window frame structure, and to form a continuous window frame structure divided in appearance and structure. With the window frame structure 1, it is possible to reduce the proportion of the frame material of the window frame structure to the entire daylighting wall and to form a daylighting wall with improved design.
