BEST MODE FOR CARRYING OUT THE INVENTION

[0009] In the following embodiments of the present invention, when necessary, they will be described separately in a plurality of sections and the like. In principle, they are not unrelated to each other, and one is related to a modification, details, etc. of a part or all of the other. For this reason, in all the figures, members having the same function are denoted by the same reference numerals, and the repeated description thereof is omitted. Also, regarding the number of components (including the number, numerical value, amount, range, etc.), unless otherwise specified or limited to a specific number in principle, it is not limited to that specific number, and it may be more than or less than the specific number. Also, when referring to the shape of components and the like, unless otherwise specified and unless it is considered otherwise in principle, it includes those substantially approximating or similar to the shape and the like.

[0010] (First Embodiment) An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a fastener receiving fitting 10 according to this embodiment. FIG. 2 is a front view of the fastener receiving fitting 10, and FIG. 3 is a plan view of the fastener receiving fitting 10.

[0011] The fastener receiving fitting 10 has a first plate portion 11 and a second plate portion 12. The first plate portion 11 and the second plate portion 12 are formed in a flat plate shape and are made of a metal such as steel. The width, length, and plate thickness of the first plate portion 11 and the second plate portion 12 can be arbitrarily set.

[0012] The first plate portion 11 has a connecting portion 15. FIG. 4 is an explanatory diagram of the connecting portion 15. The connecting portion 15 has a connecting hole 16 and is fixedly provided on the first plate portion 11. The connecting portion 15 is provided along any side of the first plate portion 11. Further, the connecting hole 16 is provided so as to face that side. Any number of connecting portions 15 can be provided on the first plate portion 11. In this embodiment, the case where three connecting portions 15 are provided on the first plate portion 11 will be described. When three or more connecting portions 15 are provided on the first plate portion 11, it is preferable to arrange them at equal intervals from each other.

[0013] The second plate portion 12 has a connecting hole 17. The connecting holes 17 are provided on the second plate portion 12 in the same number, size, and interval as the connecting holes 16 of the first plate portion 11. The first plate portion 11 and the second plate portion 12 are connected by inserting a connecting tool 18 such as a bolt through the connecting holes 16 and the connecting holes 17.

[0014] The first plate portion 11 and the second plate portion 12 have screw holes 19 and are fixed to a beam B which is a building frame with screws 20. FIG. 5 is a diagram showing a state where a fastener receiving fitting 10 is fixed to the beam B. More specifically, the first plate portion 11 is fixed to the horizontal plane Bh of the beam B, and the second plate portion 12 is fixed to the vertical plane Bv of the beam B. The first plate portion 11 and the second plate portion 12 are fixed to the beam B in a state of being connected to each other. Therefore, the second plate portion 12 is fixed to the beam B with the connecting holes 17 protruding from the horizontal plane Bh of the beam B.

[0015] The fastener receiving fitting 10 has a fastener fixing portion 25. The fastener fixing portion 25 is provided on the same surface of the first plate portion 11 as the surface where the connecting portion 15 is provided. The fastener fixing portion 25 is made of a metal such as a steel material formed in a U shape and is fixedly provided on the first plate portion 11.

[0016] The fastener fixing portion 25 has a base portion 26 for fixing the curtain wall mounting fastener F. FIG. 6 is a view showing a state in which the curtain wall mounting fastener F is fixed to the fastener fixing portion 25. The curtain wall mounting fastener F is fixed to the base portion 26 with a high-strength bolt or the like. A separate plate may be provided on the base portion 26 to adjust the mounting position of the fastener F.

[0017] The procedure for fixing the fastener receiving fitting 10 to the beam B will be described. First, the operator connects the separated first plate portion 11 and second plate portion 12 with the connecting tool 18. More specifically, the connecting tool 18 is screwed into the connecting hole 16 of the first plate portion 11 and the connecting hole 17 of the second plate portion 12 and fastened. When fastening the connecting tool 18, nuts and washers may be appropriately used as lock washers.

[0018] Next, the connected first plate portion 11 and second plate portion 12 are arranged on the beam B. When the fastener receiving fitting 10 is arranged at a position where the first plate portion 11 and the second plate portion 12 abut against the beam B, screws 20 are screwed into the respective screw holes 19 to fix the first plate portion 11 and the second plate portion 12 to the beam B. Thus, the operation of fixing the fastener receiving fitting 10 to the beam B is completed.

[0019] The effects of this embodiment will be described. Since the fastener receiving fitting 10 can be fixed without welding to the beam B, the workability at the construction site is excellent. Further, since the first plate portion 11 and the second plate portion 12 can be transported in a separated state, the delivery to the construction site and the carrying into the upper floors of the building can be efficiently performed.

[0020] When an L-shaped metal fitting for attachment to beam B is transported to a construction site, it may be distorted or warped due to impacts during transportation or the like, and may become unusable. In the fastener receiving fitting 10, even if distortion or warping occurs in the first plate portion 11 or the second plate portion 12, only the side where the distortion or warping has occurred can be replaced, and less member waste is required. Further, the fastener receiving fitting 10 is easier to correct the intersection angle between the vertical portion (first plate portion 11) and the horizontal portion (second plate portion 12) than an L-shaped metal fitting in which the vertical portion and the horizontal portion with respect to beam B are integrally joined, and has excellent workability.

[0021] Normally, since an L-shaped metal fitting is manufactured by welding two plates, welding distortion is likely to occur at the intersection portion. Regarding such distortion of the metal fitting, at a construction site, for example, as shown in FIG. 13, the L-shaped metal fitting is corrected to be horizontal with respect to beam B using the head of a screw or the like. Needless to say, such precise work is a burden on the operator. Since the fastener receiving fitting 10 according to the present embodiment is not welded at the portion in contact with beam B, welding distortion that becomes an obstacle to attachment does not occur. Therefore, less labor is required for correction, and workability is excellent.

[0022] Since the first plate portion 11 and the second plate portion 12 are connected in a vertically intersecting posture, they can be arranged in a state of being properly in close contact with a prismatic beam B such as a beam made of fire-resistant coated laminated wood. Different from the L-shaped metal fitting, the fastener receiving fitting 10 is less likely to have an error in the intersection angle due to welding distortion or the like during the manufacturing process, and is easy to attach in a state of being properly in close contact with the bent portion of the prismatic beam.

[0023] Since the first plate portion 11 and the second plate portion 12 can be attached to beam B in a state of being properly in close contact, it is possible to prevent the situation where the first plate portion 11 and the second plate portion 12 bite into the fire-resistant coating of beam B. Thereby, the fastener receiving fitting 10 can maintain the thickness of the fire-resistant coating required for beam B. Due to the features of being attachable to beam B without welding and being able to prevent biting into the fire-resistant coating, the fastener receiving fitting 10 is particularly suitable as a member to be attached to a wooden beam.

[0024] Since the first plate portion 11 is separated from the second plate portion 12, the position of the fastener fixing portion 25 on the beam B can be flexibly determined according to the attachment position of the curtain wall or the shape of the fastener F. For example, when it is desired to move the position of the fastener fixing portion 25 in the front-rear direction of the beam B (for example, the left-right direction in FIG. 5), the connector 18 may be tightened or loosened. If the fastener fixing portion is pre-welded or the like to an L-shaped jig, it is not easy to correct the position of the fastener fixing portion at the site. That is, the fastener receiving fitting 10 is excellent in workability.

[0025] When metal fittings, screws, etc. are embedded in the beam for connecting the column and the beam, usually, the L-shaped metal fitting is attached at a position where it does not interfere with the metal fittings, screws, etc. Even in such a case, since the first plate portion 11 and the second plate portion 12 of the fastener receiving fitting 10 are separated and the positions of the first plate portion 11 and the second plate portion 12 can be appropriately adjusted by tightening the connector 18, it is easy to attach while avoiding the metal fittings embedded in the beam. That is, the fastener receiving fitting 10 is excellent in workability.

[0026] The connecting portion 15 and the fastener fixing portion 25 can be fixed to the first plate portion 11 by various methods. When welding, for example, the first plate portion 11 may be made thicker than the second plate portion 12 to ensure sufficient thickness of the first plate portion 11. Welding distortion of the first plate portion 11 can be prevented, and the fastener receiving fitting 10 can be brought into close contact with the beam. The connecting portion 15 and the fastener fixing portion 25 may be bolted to the first plate portion 11. Welding distortion is not generated in the first plate portion 11, and the fastener receiving fitting 10 can be brought into close contact with the beam.

[0027] (Second Embodiment) Another embodiment of the present invention will be described. FIG. 7 is a side view of the fastener receiving fitting 10A according to this embodiment. FIG. 8 is a front view of the fastener receiving fitting 10A, and FIG. 9 is a plan view of the fastener receiving fitting 10A.

[0028] The fastener receiving fitting 10A has a first plate portion 11A and a second plate portion 12A formed on a flat plate. The second plate portion 12A has a connecting portion 40, and the first plate portion 11A has a connecting portion 42. FIG. 10 is an explanatory diagram of the connecting portion 40 and the connecting portion 42. The connecting portion 40 has a connecting hole 41 and is fixedly provided on the second plate portion 12A. The connecting portion 42 is a protrusion provided on the plane of the first plate portion 11A and has a diameter corresponding to the opening diameter of the connecting hole 41. The first plate portion 11A and the second plate portion 12A are connected by the fitting of the connecting portion 40 and the connecting portion 42.

[0029] The procedure for fixing the fastener receiving fitting 10A to the beam B will be described. FIG. 11 is a diagram showing a state where the fastener receiving fitting 10A is fixed to the beam B. First, the operator places the first plate portion 11A on the beam B, and then connects the first plate portion 11A and the second plate portion 12A in a separated state. More specifically, the connecting portion 40 and the connecting portion 42 are fitted and connected.

[0030] Next, screws 20 are screwed into the respective screw holes 19 to fix the first plate portion 11A and the second plate portion 12A to the beam B. Thus, the operation of fixing the fastener receiving fitting 10A to the beam B is completed.

[0031] The effects of this embodiment will be described (note that the effects described in the first embodiment will be omitted because they are repetitive). Since the fastener receiving fitting 10A does not require a connecting tool for connecting the first plate portion 11A and the second plate portion 12A, the connection is easy and the workability is excellent.

[0032] (Third Embodiment) Another embodiment of the present invention will be described. FIG. 12 is an explanatory diagram of a fastener receiving fitting 10B according to this embodiment. The fastener receiving fitting 10B has a first plate portion 11B formed on a flat plate, a second plate portion 12B, and a fastener fixing portion 25B as a connecting portion. The fastener fixing portion 25B is made of a metal such as a steel material formed in a U-shape and is fixed to the first plate portion 11B.

[0033] The fastener receiving fitting 10B has a groove capable of sandwiching the second plate portion 12B, and the first plate portion 11B and the second plate portion 12B can be connected by fitting them together. Since the fastener receiving fitting 10B does not require a connecting tool for connecting the first plate portion 11B and the second plate portion 12B, the connection is easy and the workability is excellent.

[0034] The fastener fixing portion 25B may be fixed to the second plate portion 12B, and the first plate portion 11B may be sandwiched by the fastener fixing portion 25B.

[0035] As described above, the present invention has been specifically described based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist thereof. For example, a fitting or the like may be attached to the second plate portion 12 so that other members can be fixed to the second plate portion 12. The fastener receiving fitting 10 may be used for purposes other than attaching the curtain wall. Thus, the fastener receiving fitting 10 is versatile and has excellent expandability of functions, and is particularly suitable for work at a construction site.
