Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a brace fixing bracket for wooden construction.

[0002]

[Prior art]

 To fix the end of the brace to the intersection where the horizontal members such as the foundation of the wooden construction, cross beams, girders and the vertical members such as columns cross at right angles, make the end face of the end of the brace perpendicular to the horizontal member. Keep the shape close to the corners of the timber crossing and fix it by diagonally striking the nail from the bracing material to the horizontal or vertical material, or by tapping the side with a short metal fitting. It is reinforced.

[0003]

[Problems to be solved by the device]

 When the building shakes back and forth, left and right, twists, and vibrates up and down due to an earthquake, the true value of the brace of the building is demonstrated. At that time, the joints between the brace members and the foundations, beams and columns are alternately subjected to compression and tension. When it is pulled, the diagonally driven nails loosen and the brace does not work. The reason why the nails loosen is that the wood is easily broken at the ends of the wooden brace. There is a reinforcing effect if a short metal fitting is struck on the side surface of the joint, but the bracing material is fixed on the side surface of the base or column, and since the metal fitting is generally flat, it can be attached to the left, right, top, and bottom. The base, columns, and brace members cannot be firmly fixed to a severe earthquake that is subject to external forces such as tension, compression, and torsion, and they are weak. The purpose of this invention is to enhance the reliability of wooden construction brace members to the level of reinforced concrete construction.

[0004]

[Means for Solving the Problems]

 This invention is a bracing member that has one horizontal surface and four vertical surfaces integrally by making a cut in a part of one metal plate, bending it up and down and laterally, and fixing the overlapping part by welding. It was used as a fixture. One horizontal surface and one vertical surface are applied to the corners of the building horizontal members, two vertical surfaces are applied to the building vertical members and the bracing members, respectively, and fixed with nails or bolts, and the remaining one vertical surface is the bracing vertical surfaces. It becomes the reinforcement bone of.

[0005]

[Embodiment of the invention]

 This bracing material fixing metal fitting for wooden construction is a fixing metal fitting for fixing the end portion of the bracing material to the crossing portion where the horizontal and vertical materials of the wooden construction directly intersect with each other. By making a cut and bending it in the vertical and horizontal directions, one horizontal plane (4a) and one of the two sides that sandwich the right angle of the horizontal plane are folded down, and the other is folded up. (4b), the folded vertical plane (4c) and a part of the folded vertical plane (4c) are bent at a right angle in the lateral direction onto the horizontal plane (4a), and the lower edge thereof is on the horizontal plane (4a). The horizontal bending vertical surface (4d) and the portion of the horizontal bending vertical surface (4d) extending from the horizontal surface (4a) are bent horizontally along the edge of the horizontal surface (4a). A horizontal bending vertical surface (4e) for reinforcing the lower edge of which is welded to the edge portion, and the horizontal surface (4a) and The lower vertical surface (4b) is applied to the corner of the horizontal member, the folded vertical surface (4c) is applied to the side surface of the vertical member, and the lateral bending vertical surface is applied to the end surface of the brace member. The feature is that it is fixed.

【Example】

 Fig. 1 shows a part of wooden construction to which the present invention is applied. No. 1 is a horizontal member (base, cross beam, cross girder), 2 is a vertical member (column), 3 are brace members, 4 and 4 are brace fixing fittings. FIG. 2 is an enlarged cross-sectional view of FIG. 1, and the thicknesses of the horizontal members 1 and the vertical members 2 and the thickness and arrangement of the brace members 3 can be seen. 3 and 4 show the AA cross section and the BB cross section of FIG. 1, and show how to use two kinds of fixing fittings 4 and 4'with FIG.

In FIGS. 1 to 4, since the shapes of the fixing brackets 4 and 4 ′ are difficult to understand, a perspective view (A) and a plan view (B) of the metal plate before bending are shown in FIGS. 5 and below. The fixing bracket 4 in FIG. 5 (A) is composed of only one horizontal surface 4a, a vertical folding surface 4b, a vertical folding surface 4c, a lateral bending vertical surface 4d, and a reinforcing lateral bending vertical surface 4e. . Looking at the metal plate 4p before bending in FIG. 5 (B), it is a flat plate with only the cuts 5 and the folds are indicated by chain lines at the boundaries of the surfaces 4a to 4e. When these folds are folded at right angles, it becomes as shown in FIG. 5 (A), and the fixing metal fitting 4 is completed by providing the welded portion W between the lower edge of the reinforcing horizontal bending vertical surface 4e and the edge of the horizontal surface 4a. In this embodiment, the lower edge of the lateral bending surface 4d is also welded to the horizontal surface 4a by welding W. However, the presence / absence of welding at this portion may be determined according to the operating conditions. Simple temporary welding may be used.

The fixture 4'of FIG. 6 is a perspective view of that of FIGS. As can be seen clearly in FIGS. 1 and 2, one of the two intersecting brace members 3 is fixed by a fixing member 4 and the other is fixed by a fixing member 4 '. Comparing the two fixing brackets 4 and 4'in FIGS. 5 and 6, the so-called right-handed and left-handed parts are made, and the reinforcing lateral bending vertical surfaces 4e and 4'e are opposite in direction. I understand. The reason for this is that the fixing member 4 is attached to the right side vertical member 2 shown in FIG. 2 and the fixing member 4'is attached to the left side vertical member 2. Since both of the reinforcing vertical bending vertical surfaces 4e and 4'e stand on the front side and the back side of the brace 3, the shapes are as shown in FIGS. 5 (A) and 6 (A).

Although the driving positions of the nails 6 are illustrated in the respective drawings, it is possible to leave it to a field engineer how to arrange the nails 6 and from which side the nails 6 are driven. When driving the nail 6 from the side of the fixing metal (lower part of FIGS. 3 and 4), the nail hole 7 showing the arrangement of the nails may be opened, but when driving from the timber side (upper side of FIGS. 3 and 4) Is useless. When the nail 6 driven in from the timber side penetrates the plate surface of the fixing metal piece as in the upper part of FIGS. 3 and 4, the burr of the through hole holds the nail 6 and becomes difficult to come off. In the fixing fittings 4 and 4'of the above embodiment, nail holes 7 are provided on the horizontal planes 4a and 4'a, the folding vertical planes 4b and 4'b, and the folding vertical planes 4c and 4'c. Only the mark may be used instead of the hole.

The inventor of the present invention has already developed a similar brace member fixing bracket, and has already registered it as a utility model No. 3 025693. The present invention further strengthens the rigidity of the lateral bending vertical surface 4d for fixing the brace by adding the reinforcing lateral bending vertical surface 4e. Although the embodiment of FIGS. 5 and 6 has achieved the above-mentioned object, the embodiment of FIGS. 7 and 8 has the lateral bending vertical surface 4d or 4'd in order to further increase the rigidity of the lateral bending vertical surface. It has both vertical and horizontal reinforcing bones.

Referring to FIG. 7, this is because the metal plate 4p of FIG. 5B is provided with new cuts 5a, 5a as shown in FIG. 7, and the cuts are made as shown in FIG. 5a and 5a are horizontally folded to form a reinforcing horizontal surface 4f as shown in FIG. 7 (A). It goes without saying that the reinforcing horizontal surface 4f is bent in such a direction that it does not interfere when fixing the bracing member to the laterally bent vertical surface 4d. In FIG. 8, new cuts 5a and 5a are added to the metal plate 4'p of FIG. 6 (B) to form the reinforcing horizontal plane 4'f of FIG. 8 (B), and after folding as shown in FIG. 6 (A), As shown in FIG. 8 (A), the reinforcing horizontal surface 4'f is folded in a direction that does not interfere with the brace members.

Although a few embodiments have been described above, it goes without saying that the present invention can be variously changed depending on the execution conditions without changing the gist thereof. The outer shape of the metal plate before bending, each horizontal surface, and the vertical surface are not necessarily all rectangular as illustrated. Instead of drilling multiple nail holes, it is naturally possible to drill a small number of bolt holes. The above-mentioned embodiment was considered only the strength aspect for development, and the consideration of the product as a practical product is left to the practitioner of this invention.

[Effect of the invention]

 The present invention focuses on the weakness of the traditional wooden construction braces, which is the resistance to the force that separates the ends of the braces from the intersections of horizontal and vertical timbers of the building, and proposes strengthening measures. It was Since the fixing bracket of this invention is made of a single metal plate, when the bracing member tries to be released from the fixed position, the fixing bracket 4 is bent through the laterally bent vertical surface 4d and the folded vertical surface 4c so that The vertical member 2 stops. When the vertical member 2 of the building tries to rise, the horizontal member 1 of the building comes to a stop through the folded vertical surface 4c, the horizontal surface 4a, and the folded vertical surface 4b. Further, since the laterally bent vertical surface 4d is fixed to the horizontal surface 4a, the lifting of the brace members 3 can be directly stopped by the horizontal members of the building. The greatest effect of the present invention is that by adding a reinforcing lateral bending vertical surface 4e obtained by folding the free end of the lateral bending vertical surface 4d for fixing the bracing member 3 and welding the lower edge thereof to the horizontal surface 4a. The rigidity of the laterally bent vertical surface 4d is remarkably increased to facilitate the nailing work of the brace members 3 and to improve the earthquake resistance.
