Description

  The present invention relates to an attachment structure for attaching a joinery frame to an opening of a structural frame, an attachment method for a joinery frame using the attachment structure, and an attachment fitting.

Conventionally, in order to attach a joinery frame that accommodates a joinery to the opening of the structural housing, for example, as shown in FIG. 17, an anchor 4 is previously attached to a mold (not shown) for molding the opening 3 of the structural housing 2. After placing the concrete, the exposed portion 5 of the anchor 4 and the connecting portion 6 of the joinery frame 7 are welded through the welding material 8, and the mortar is placed in the gap between the joinery frame 7 and the structural frame 2. The fitting frame 7 was fixed to the opening 3. In addition, as shown in FIG. 18, the angle (section steel) 19 provided in the lightweight cellular concrete structural frame (ALC) 2 </ b> A and the connecting portion 6 of the joinery frame 7 are welded through the welding material 8. In such a conventional method, since the joinery frame is fixed by welding, for example, when working on a high floor, sparks scatter to the lower floor and damage the joinery such as glass already attached. There is a fear. For this reason, in recent years, a mounting structure has been proposed in which a fixture is embedded in the opening of the structural frame in advance and welding is not used, and the fixture and the joinery frame are attached. As shown in FIG. 19, this attachment structure is formed with a slit 9A in which the nut 8 cannot be pulled out on the upper surface of the box-shaped anchor 9 in which the nut 8 is loaded in advance so that the nut 8 can be moved. A bolt (not shown) is inserted, and the bolt and the nut 8 are screwed together (see Patent Document 1).

FIG. 1 is a perspective view showing an attachment structure according to a first embodiment of the present invention. As shown in FIG. 1, the mounting structure 10 according to the present embodiment includes a mounting tool 11 and a connection fitting (connecting tool) 12 that is attached to the mounting tool 11. As shown in FIGS. 2A to 2D, the fixture 11 includes an elongated box-shaped metal main body 13, and an upper surface portion 14 having a flat upper surface is formed on the main body 13. The upper opening is closed. The upper surface part 14 is formed such that both ends 14A, 14B in the longitudinal direction protrude from both end walls 13A, 13B in the longitudinal direction of the main body 13 to form a temporary fastening part. Temporary fastening holes 15 and 16 are formed in the temporary fastening portions 14A and 14B at both ends of the upper surface portion. The upper end of the J-shaped anchor 18 is welded to the bottom surface 17 of the main body 13. A space is formed in the main body 13 by an upper surface portion 14, end walls 13 </ b> A and 13 </ b> B, side walls 13 </ b> C and 13 </ b> D and bottom surfaces 17 formed on both sides in the width direction.

  By the way, a guide 20 is formed on the upper surface portion 14 between the temporary fixing portions 14A and 14B. The guide 20 has a slit 21 drilled along the center of the upper surface portion 14, and an introduction port 22 that is continuous with the slit 21 and formed in the width direction of the upper surface portion 14 at one end of the slit 21. . A latching portion 31 of the connection fitting 12 to be described later is inserted into and removed from the introduction port 22 (see FIG. 4). The slit 21 guides with play without dropping the latching portion 31 of the connection fitting 12.

  As shown in FIGS. 3A to 3B, the connection fitting 12 is composed of an L-shaped fitting whose lower end is bent, and the width is formed so as to substantially match the width of the upper surface portion 14. And a bent lower part 32 having a dimension L2 (L1 <L2) longer than the width dimension L1 of the slit 21 between the bent part and the end part. The connection part 31 is formed with a screw hole 33 connected to the attachment parts 41A and 42A of the joinery frames 41 and 42 (see FIGS. 6A and 6B) through screws 43. A hooking portion 35 is provided in the bent lower portion 32. The hook 35 is screwed with a screw 34 from above into a screw hole formed in the bent lower portion 32, and a square plate 36 is separated from the bent lower portion 32 at a predetermined distance M1 at the lower end of the screw 34. It is formed by screwing. The plate 36 has a dimension L3 (L1 <L3) in which each side passes through the gap of the introduction port 22 and is longer than the width dimension L1 of the slit 21. The outer diameter of the screw portion 34A of the screw 34 is smaller than the width dimension L1 of the slit 21 and can move along the slit 21 with play. The hooking portion 35 inclines the connection fitting 12 and inserts the plate 36 into the introduction port 22, and when the screw portion 34 </ b> A of the screw 34 is guided to the slit 21, the plate 36 is guided to the inside of the main body 13, and the connection fitting 12 is attached to the fixture. 11 is attached. The distance M1 of the screw screw portion 34A between the bent lower portion 32 and the plate 36 is set to be longer than the thickness dimension of the upper surface portion 14 so that the connection fitting 12 can be freely moved along the slit 21. It has become. Moreover, even if the connection fitting 12 is upside down with respect to the main body 13 and may be positioned on the lower side, the plate 36 prevents the connection fitting 12 from falling off.

  In this manner, the latching portion 35 can be inserted into and removed from the introduction port 22 and is guided by the slit 21 so as to be movable along the longitudinal direction of the main body 13. For this reason, a desired connection fitting 12 can be selected and attached to the fixture 11 from the outside. Therefore, even if the positions of the attachment portions 41A and 42A of the joinery frames 41 and 42 are slightly deviated, the connection tool 12 can be accurately attached according to the positions of the attachment portions 41A and 42A. Can be done. Further, the hooking portion 35 is fixed to the fixture 11 when the screw 34 is screwed to bring the plate 36 into close contact with the inside of the upper surface portion 14.

  Next, the attachment frame attaching method using the attachment structure will be described based on the action of the attachment structure according to the embodiment and the action. Of the mounting structure 10 according to the above embodiment, the mounting tool 11 is temporarily secured to the mold 40 in advance as shown in FIG. Temporary fastening is performed by attaching a curing tape (not shown) to the upper surface portion 14 of the fixture 11 and bringing it into contact with the mold 40, and temporarily fastening it with the nail 44 through the temporary fastening holes 15 and 16. The position of temporary attachment is determined corresponding to the position of the attachment parts 41A and 42A of the joinery frames 41 and 42 to be built in the opening 3 of the structural housing 2. After the fixture 11 is attached to the mold 40, concrete is cast, and after curing, the mold is removed, and when the curing tape (not shown) is peeled off, the fixture 11 is in a state where the upper surface portion 14 is exposed to the opening 3. It is embedded in the structural housing 2 (see the first step, FIG. 6). The nail 44 is buried. In addition, it is not necessary to stick a curing tape if concrete does not have a possibility of entering from the slit 21 and the inlet 22 at the time of placement. Next, the connection fitting 12 in which the screw holes 33 are fitted to the attachment portions 41A and 42A of the joinery frames 41 and 42 is selected, and the connection fitting 12 is led from the introduction port 22 to the slit 21 and attached to the attachment 11 (second). Process).

  Next, the screw holes of the attachment portions 41A and 42A and the screw holes 33 of the connection fitting 12 are combined and connected by screws 43, and the joinery frames 41 and 42 and the attachment 11 are connected through the connection fitting 12 (third Process). At this time, even if the positions of the attachment portions 41 </ b> A and 42 </ b> A and the connection fitting 12 are deviated, the connection fitting 12 can be moved along the slit 21, so that the connection can be reliably made at an accurate position. For example, even when the connection fitting 12 does not fit the attachment portions 41A and 42A, the connection fitting 12 can be removed from the attachment 11 and another appropriate connection fitting 12 can be replaced. Moreover, since the latching part 35 has a play and is latched by the slit 21, even if there exists a slight position shift about the width direction of the upper surface part 14, the attachment part 41A is reliably ensured by inclining the connection metal fitting 12. , 42A.
