Description

  The present invention relates to a structure for attaching a sash frame in a steel frame wall construction method.

  As a lightweight steel frame assembly wall construction method suitable for prefabricated houses and the like, the present applicant has developed and put into practical use a mounting structure of a steel framework and an outer wall panel as shown in Patent Documents 1 to 3, for example. In this mounting structure, as shown in FIGS. 5 and 6, a lip groove steel 10 is rectangularly framed to form a shaft assembly panel 1, and the shaft assembly panel 1 is built adjacent to each other to be paired. The lip channel steel 10 constitutes a shaft column 100 which is connected with the openings of each other back to back. And as shown in FIG. 6, the outer wall panel 3 which provided the groove 31 in the side edge part is being fixed to the shaft assembly through the outer wall panel mounting bracket 2 hung on this axial pillar 100. As shown in FIG. The axial column 100 and the outer wall panel 3 are allocated in accordance with a predetermined module core N. Thereby, the standardization of the member which comprises a wall body, and the improvement of workability are aimed at.

  By the way, in such a steel frame assembly, when the sash for the opening is attached to the inside of the shaft assembly panel 1, the opening of the shaft column 100 (lip channel steel 10) is directed to the sash side. For example, it is difficult to attach a commercially available wooden shaft sash as shown in Patent Document 4 to the shaft column 100, and a special fit is required for mounting the shaft column 100 and the sash frame.

  FIG. 7 shows an example of a mounting structure of the exclusive sash frame 4 that has been conventionally adopted by the applicant. In the illustrated mounting structure, a mounting piece 41 is provided on the outer side of the sash frame 4 so as to project outward from the opening surface, and the mounting piece 41 is extended to a position covering the outdoor-side finding surface of the shaft column 100. The mounting piece 41 is fixed to the shaft column 100 by engaging with the outer wall panel mounting bracket 2 hung on the shaft column 100. Further, a decorative frame portion 42 is integrally formed on the outdoor side of the mounting piece 41, and the decorative design is arranged so that the decorative frame portion 42 is continuous with the exterior material 32 of the outer wall panel 3.

However, as described above, it is uneconomical in terms of time and cost to prepare the dedicated sash frame 4 that matches the shaft column 100 made of the lip groove steel 10. In addition, since a wide variety of commercially available sashes provided by a sash maker cannot be easily used, the degree of freedom of selection in terms of design and functionality is limited.

It is characterized in that an airtight waterproof tape is applied over the surface.

  The mounting structure of the sash frame of the present invention is configured so that the base wood attached to the opening of the shaft column made of lip groove steel is used as a base for fixing the sash frame. And, using a prospective surface, a general commercially available type wooden frame sash can be accommodated well.

  Furthermore, from the outdoor side finding surface of the lip groove steel to the outdoor side finding surface of the base wood, an appropriate auxiliary frame such as an outer wall panel, a shutter shutter rail frame or the like is preferably covered so as to cover these surfaces. Can be attached.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 2 show a first embodiment of the present invention. Reference numeral 10 denotes a shaft column constituting a part of the shaft panel. The shaft column 100 is configured by connecting a pair of lip groove steels 10 so that their openings are back to back. The outer wall panel 3 is attached to the outdoor side of the shaft assembly panel via an outer wall panel mounting bracket 2 that is attached to the shaft column 100.

  As shown in FIG. 2A, the outer wall panel mounting bracket 2 has two pressing pieces 22 that are rotatably attached to the substrate 21, and a concave provided on the side edge of the outer wall panel 3. The outer wall panel 3 is fixed so as to be pressed against the shaft column 100 by engaging the holding piece 22 which is turned sideways with the groove 31. The substrate 21 includes a positioning projection 23 inserted into a gap between the pair of lip groove steels 10 and a spring steel plate clip member 24 fitted to one of the lip groove steels 10. Mounted on the outer face. However, in the present invention, the means for fixing the outer wall panel mounting bracket 2 to the shaft column 100 is not particularly limited. Moreover, the outer wall panel 3 is previously attached to the lip groove steel 10 of each axle panel 1 using the outer wall panel mounting bracket 2 having one holding piece 22 as shown in FIG. It is also possible to construct a shaft assembly by incorporating this. On the indoor side of the shaft assembly panel 1, an interior material 13 is stretched through an appropriate heat insulating material 11, interior base material 12, and the like.

  The main part of the present invention resides in the base wood 5 attached to the lip channel steel 10 on one side (right side in FIG. 1) of the shaft column 100 close to the opening side of the wall surface. As shown in FIG. 1, the base wood 5 includes a fitting convex portion 51 having a substantially convex cross section on one side surface, and the fitting convex portion 51 is fitted into the opening of the lip groove steel 10. In this manner, the shaft column 100 is attached. In the illustrated form, in order to improve the insertion property and adhesion of the lip channel steel 10 into the opening, one side end surface of the fitting convex portion 51 is tapered and the other side end surface is a contact surface. It is formed to be orthogonal.

  The base wood 5 and the shaft column 100 are coupled by a bolt member 61 that passes through these in the in-plane direction of the shaft assembly. The bolt member 61 is inserted into a plurality of bolt insertion holes (not shown) formed at appropriate intervals in the vertical direction on the web of the lip groove steel 10 and the base wood 5 constituting the shaft column 100. The outer wall panel mounting bracket 2 is attached so as not to interfere. Further, a counterbore 52 for sinking the head of the bolt member 61 is formed in the base wood 5. An airtight waterproof tape 62 is attached as needed from the outdoor side finding surface of the lip groove steel 10 to the outdoor side finding surface of the base wood 5.

  The sash frame 40 and its peripheral members are attached to the shaft column 100 and the base wood 5 thus integrated. Many of the commercially available sash frames for wooden frames are screwed from the inside of the opening to the appropriate base member placed outside the opening, and the outside direction of the sash frame. A structure is adopted in which the mounting piece protruding from the outside is screwed to the base member or the like from the outdoor side. The illustrated sash frame 40 is a heat-insulating sash frame in which an outdoor half and an indoor half are joined via a heat-insulating resin, but a mounting piece 41 projects outwardly from the outdoor half. . The base wood 5 is formed so that its outdoor-side finding surface just contacts the mounting piece 41 protruding from the sash frame 40, and these overlapping portions are fixed by screws 63 from the outdoor side. In addition, the indoor half of the sash frame 40 is fixed to the expected surface of the base wood 5 by screws 64 from the inside of the opening surface. The indoor frame material 14 is also attached between the indoor half of the sash frame 40 and the base wood 5.

  In this way, by adopting a housing in which the sash frame 40 is fixed to the base wood 5 attached to the shaft column 100, the workability of the sash frame 40 is improved in each stage. The cross-sectional shape of the base wood 5 needs to be designed so that the outdoor-side finding surface and the prospective surface when attached to the shaft column 100 are appropriately positioned in accordance with individual wooden frame sash frames. Although it is wood, individual processing is much easier than metal materials.

  When the shaft column 100 and the sash frame 40 are thus connected, the exterior of the sash frame 40 is finished. Since the shaft column 100 is arranged in a predetermined module core N, and there is a gap between the shaft column 100 and the sash frame 40, it is necessary to cover this part with an exterior material or a cosmetic member and further waterproof it. There is. In the illustrated embodiment, a narrow outer wall panel 3 </ b> A is stretched between the shaft column 100 and the sash frame 40. Similar to the outer wall panel 3 for the general part, the outer wall panel 3A for the narrow width has the groove 31 on both side edges, and the groove 31 located on the module core N side is hooked on the shaft column 100. It engages with the outer wall panel mounting bracket 2 that is worn. Further, the concave groove 31 positioned on the sash side is engaged with the clip member 7 screwed to the base wood 5 together with the attachment piece 41 of the sash frame 40. The clip member 7 includes a base piece 71 fixed to be overlapped on the outdoor side of the mounting piece 41, an arm piece 72 protruding to the outdoor side from the edge of the base piece 71, and a cross-section reversed from the tip of the arm piece 72. The claw piece 73 is configured to hold the outer wall panel 3 by being elastically engaged with the concave groove 31. A waterproof sealing material 65 is fitted into the joint between the outer wall panel 3A for the narrow width and the outer wall panel 3 for the general portion, and the gap between the outer wall panel 3A for the narrow width and the sash frame 40.

  According to such a configuration, the outer wall panel 3 can be continuously stretched up to the immediate vicinity of the sash frame 40. Therefore, for example, it is convenient for a design that wants to emphasize the design of the exterior material 32 without making the design of a commercially available wooden frame sash frame more noticeable than necessary.

  3 to 4 show a second embodiment of the present invention. FIG. 4 is an exploded view of each member in order to make the shape of the member shown in the cross-sectional view of FIG. 3 easier to understand. A configuration of a shaft column 100 made of a pair of lip channel steels 10, a configuration in which the outer wall panel 3 is fixed to the shaft column 100 via the outer wall panel mounting bracket 2, a configuration in which the base wood 5 is attached to the shaft column 100, and a sash The structure in which the frame 40 is screw-fixed to the base wood 5 is the same as in the first embodiment, and a detailed description thereof is omitted. In addition, the base wood 5 which concerns on this 2nd Example partially cut off the indoor side half part of the prospective surface on the relationship with the frame material on the indoor side.

  In this embodiment, a shutter shutter rail frame 81 is attached between the shaft column 100 and the sash frame 40 instead of the outer wall panel 3. The shutter shutter rail frame 81 is attached via an auxiliary base material 82 and an attached frame attachment 83.

  The auxiliary base material 82 has a substantially rectangular cross-sectional shape, and is fixed to the outdoor-side finding surface of the base wood 5 with screws 65 so as to contact the outside of the sash frame 40.

  The accessory frame attachment 83 has a shaft assembly side fixing piece 84 having a substantially L-shaped or substantially U-shaped cross section at one side edge portion thereof, and a sash side fixing having a substantially L-shaped cross section at the other side edge portion. It has a piece 85. Then, the shaft assembly side fixing piece 84 is engaged and fixed to the outer wall panel mounting bracket 2 hung on the shaft column 100, and the sash side fixing piece 85 is fixed to the outdoor side finding surface of the auxiliary base material 82. It is fixed by screws 66. A waterproof sealing material 65 is fitted into the joint between the auxiliary frame attachment 83 and the outer wall panel 3 for the general part, and the gap between the auxiliary frame attachment 83 and the sash frame 40. Then, on the outdoor side of the incidental frame attachment 83, an appropriate incidental frame such as a shutter shutter rail frame 81 and other equipment and decorative materials attached to the sash frame 40 is attached. The cross-sectional shape of the accessory frame attachment 83 and the accessory frame can be appropriately designed according to the purpose and application.

  In addition, without attaching an incidental frame to the incidental frame attachment 83, the surface of the incidental frame attachment 83 can be exposed as it is as a cosmetic finish. Regardless of whether the attached frame is attached or not, the use of the attached frame attachment 83 makes the sense of design variation in the case of using the commercially available wooden frame sash frame 40 inconspicuous. Thus, it is easy to form a unity in the appearance design around the opening.
