Therefore, the brace material is provided along the longitudinal direction of the large lumber. Will be. Therefore, the maximum length of the brace material is limited to the length from the bracket to the lower part of the floor support leg arranged across the bracket, and the brace material hits the floor support leg, so make it longer. There is a problem that it cannot be done. If the length of the brace material is limited in this way, for example, the workability is poor because the reinforcement work cannot be performed only because the dimensions of the brace material prepared in advance are different. The mounting angle of the brace material is also limited due to contact with the floor support legs.
Further, since the conventional floor support structure described above has a structure in which a bracket made of a flat plate is fixed to the side surface of the large lumber and one end of the brace material is fixed to the bracket, the mounting direction of the brace material is also limited. For example, the brace material may be provided in a direction orthogonal to the longitudinal direction of the large pulling material, or the brace material may be provided at a certain angle in the horizontal direction with respect to the longitudinal direction of the large pulling material so as to avoid the floor support legs. If it is provided, it is necessary to use brackets having different shapes, and there is also a problem that brackets having a plurality of types are required.
Furthermore, as is the case with Patent Document 1 described above, as the brace material conventionally used as a diagonal material, a brace material having a battledore-shaped portion such as a battledore bolt at both ends is generally used ( Patent Document 2). Then, the above-mentioned brace material is used by fixing the battledore-shaped portions at both ends to a braille racket made of a flat plate with bolts. Therefore, there remains a problem that the strength of the connecting portion between the brace material and the bracket is not so high.
The present invention solves the above-mentioned conventional problems, and there are no restrictions on the length of the brace material, the mounting angle with respect to the horizontal plane, and the mounting direction, and it is possible to use the brace material of any length. The brace material can be fixed to the large pulling material at any mounting angle and mounting orientation, and in the present situation where it is necessary to improve the seismic structure, the conventional floor support for fixing the wing plate-shaped part to the brecket made of flat plate.

The brace fixing unit is fixed to the material so that the fixing metal fittings are at an appropriate angle with respect to the length direction of the large pulling material on the horizontal plane, and the bottom plate portion and the bottom plate are fixed at appropriate positions on the foundation surface. A lower brace fixing bracket having a pair of brackets having brace mounting holes extending upward from both sides of the portion is fixed, and between the pair of brackets of the fixing bracket in the brace fixing unit and the lower brace fixing bracket. In a state where the pair of side surfaces of both ends of the brace material having at least a pair of opposite side surfaces are sandwiched between the pair of brackets in the above, the brace material is paired by a fastener through a brace mounting hole of the bracket. It is fixed to the bracket of. As described above, in the floor support structure according to the present invention, the brace fixing unit and the lower brace fixing bracket each include a pair of brackets, and the pair of side surfaces of the brace material are sandwiched between the brackets of the fixing brackets. Since it is fixed by, it has the same effect as that described for the brace fixing unit described above. Further, in the floor support structure according to the present invention, a steel material having high strength itself such as square steel, H-shaped steel, C-shaped steel or round steel can be used as the brace material, and both ends of the brace material are attached to a pair of brackets. Since it is fixed by sandwiching it between them, the strength at the connecting part of the brace material is increased, compared to the case where the wing plate part is fixed to one bracket with bolts, etc., square steel, H-shaped steel, C-shaped steel, round steel, etc. Combined with the high strength of the material itself having a pair of side surfaces, the support strength of the floor is high.
Further, the fixing bracket in the brace fixing unit is positioned at a predetermined angle in the horizontal plane with respect to the longitudinal direction of the large pulling material, whereby the brace material after mounting holds the floor support leg.

Compared to the brace material having a battledore-shaped portion, its own strength is high. Further, by sandwiching the brace material between the pair of brackets 3 and fixing them from both sides, the supporting strength of the connecting portion is higher than that of the conventional brace material in which the battledore-shaped portion is fixed to one bracket. Therefore, it is possible to increase the support strength of the entire floor support structure. Further, it is not necessary to use a brace material having a special structure in order to increase the support strength of the floor support structure, and general steel materials such as square steel, H-shaped steel, C-shaped steel or round steel can be used. , The cost does not go up.
Further, by arranging a plurality of brace mounting holes 4 in the bracket 3 in a matrix, at least one brace mounting hole 4 is always formed with the brace material regardless of the angle at which the brace material is arranged between the brackets 3. Since they face each other, it is easy to attach the brace material.

Next, the configuration of the support metal fitting 5 in the brace fixing unit X according to the present invention will be described with reference to FIGS. 5 and 6.
The support metal fitting 5 is formed by bending a steel plate into a U shape, and a cushion material 5a is provided on the inner surface thereof. A protrusion 6a that protrudes upward in a cylindrical shape is formed in the central portion of the bottom plate portion 6 of the support metal fitting 5, and a screw groove is formed inside the protrusion 6a. Further, fastening holes 7a and 7a for passing the large pull fastening member 8 made of bolts and nuts are formed in the upper portions of the pair of side plate portions 7 and 7.
The distance T2 between the side plate portions 7 and 7 in the support metal fitting 5 configured as described above is sized according to the width of the large pulling material to be attached.

The assembly of the brace fixing unit X configured as described above will be described with reference to FIGS. 7 and 8.
FIG. 7 is an exploded assembly drawing of the brace fixing unit, and FIG. 8 shows the fixing bracket 1 on the support bracket 5 so that the bracket 3 is oriented orthogonal to the longitudinal direction of the large pulling member 12 in the horizontal plane. It is a figure which shows the fixed state.
As shown in FIGS. 7 and 8, the fixing bracket 1 is a fastening member via a spring washer 9a in a state where the support bracket mounting hole 2a of the support portion 2 and the protrusion hole 6a of the support bracket 5 are combined. It is fixed to the support metal fitting 5 by the bolt 9b.
More specifically, after the support metal fitting 5 is attached to the large pulling member 12, the bolt of the large pulling fastening member 8 is passed through the fastening hole 7a formed in each side plate portion 7 of the support metal fitting 5 and tightened with a nut. As a result, the support metal fitting 5 is fastened to the large pulling material 12.
The fixing metal fitting 1 is arranged on the bottom surface of the support metal fitting 5 in a state where the mounting hole 2a of the support portion 2 and the protrusion hole 6a of the support metal fitting 5 are combined. At this time, since the fixing bracket 1 has not been fixed yet, it can rotate in the horizontal plane around the mounting hole 2a. After defining the angular position of the fixing metal fitting 1 in the horizontal plane, the fixing metal fitting 1 is fixed to the supporting metal fitting 5 using the bolt 9b via the spring washer 9a (see FIG. 8).

Hereinafter, a floor support structure using the brace fixing unit configured as described above as the upper brace fixing unit will be described.

FIG. 9 is a diagram showing an embodiment of the floor support structure according to the present invention.
The floor support structure in this embodiment is
A plurality of floor support legs 11 attached to the floor slab 10 as a foundation surface, and
A plurality of large lumbers 12 supported from below by these floor support legs 11 and
The upper brace fixing unit X fixed to the large pulling material 12 and
The lower brace fixing bracket 20 fixed to the floor slab 10 and
A brace material 13 whose both ends are fixed by the upper brace fixing unit A and the lower brace fixing bracket 20 is provided.
The joist material 14 is arranged on the large lumber 12, and the floor board material 15 is laid on the joist material 14.
As the brace material used in this embodiment, a material having at least a pair of side surfaces is used, and specifically, for example, square steel, H-shaped steel, C-shaped steel, round steel, or the like can be used.

As described above, the support metal fitting 5 of the upper brace fixing unit X is fixed to the large pulling member 12, and the fixing metal fitting 1 is fixed to the support metal fitting 5 by the fastening member 9.
In this embodiment, the fixing bracket 1 is positioned so that the bracket 3 is slightly displaced in the horizontal plane with respect to the longitudinal direction of the large pulling member 12, specifically, at an angle of about 45 degrees. It is fixed. As a result, the brace material 13 supported by the fixing bracket 1 does not interfere with the floor support legs 11.

Next, the lower brace fixing member 20 fixed to the floor slab 10 will be described.

Therefore, when the brace material is arranged along the right side 23a and fixed to the bracket 23, for example, the brace material can be fixed to the floor slab 10 at an angle of 45 °. If the brace material is arranged along the left side 23b and fixed to the bracket 23, the brace material can be fixed at an angle of 60 ° with respect to the floor slab 10. These 45 ° and 60 ° are angles suitable for the arrangement angle of the brace material as the diagonal material. Therefore, according to the lower brace fixing bracket 20 configured as described above, the brace material can be easily attached at a preferable angle only by determining the fixing position of the lower brace fixing bracket 20 with respect to the floor slab 10 in advance. And the construction becomes remarkably easy. The angle between both sides of the bracket 23 and the horizon in the lower brace fixing bracket 20 can be arbitrarily set. For example, both the right side and the left side may have the same angle with respect to the horizon. , 45 ° and a combination of angles other than 60 °. Specifically, for example, the bracket 23 may be formed so that the angle between one side and the horizon is 30 °.

As described above, the side surface 13a is sandwiched between the brackets 3 of the upper brace fixing unit X fixed to the large lumber 12 and the brackets 23 of the lower brace fixing bracket 20 fixed to the floor slab 10. In the state where the upper end portion and the lower end portion of the brace material 13 are arranged, the brace material 13 is fixed to the brackets 3 and 23 by appropriate fasteners such as bolts and screws via the brace mounting holes 4 and 24. As a result, the brace material 13 is fixed at its upper end and lower end with its both side surfaces 13a sandwiched between the pair of brackets 4 and 33.

In the above embodiment, the upper brace fixing unit A is fixed so that the bracket 3 of the fixing bracket 1 is fixed at an angle slightly deviated from the longitudinal direction of the large pulling material 12 in the horizontal plane. Can prevent vibrations that sway in its longitudinal direction.

The fixing direction of the upper brace fixing unit A is not limited to this embodiment, and for example, the bracket 3 of the fixing bracket 1 is fixed so as to be located in a direction orthogonal to the longitudinal direction of the large pulling member 12. Also, by fixing in this way, it is possible to prevent the large pulling material 11 from swaying in the direction orthogonal to the longitudinal direction thereof.
Further, in the above-described embodiment, nine brace mounting holes 4 are provided in a matrix shape in the bracket 3 of the upper brace fixing unit A, but this configuration is not limited to this embodiment, and the brace mounting holes 4 are not limited to this embodiment.
