Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a column reinforcing metal fitting and a reinforcing method used to reinforce a joint to a base and a column, a column and a beam, and a column and a body difference.

[0002]

[Prior art]

 Conventionally, mounting parts such as bases and columns, columns and beams, columns and body gaps, etc. are generally reinforced with reinforcing metal fittings. For example, FIG. 9 is a perspective view showing various conventional examples in one drawing, in which reference numeral 21 is a foundation, 22 is a base, A, B, C, D and E are columns, 23 is a waist difference, Reference numeral 24 denotes an anchor bolt.

[0003] As reinforcing metal fittings, column A shows the case of a chamfer 25, columns B and D show the case of a corner hardware 26, column C shows the case of a palm hardware 27, and column E shows the case of a chevron plate 28. Show the case.

[0004]

[Problems to be solved by the invention]

 However, with the above-mentioned reinforcing metal fittings, the sharpening portions 25 are attached by sharpening the sharp portions at both ends into nails, and the corner fittings 26, the palm fittings 27, and the chevron plate 28 are attached with screws or nails. Therefore, the loads (loads) received from the columns A, B, C, D, E, the stud 23 and the like are the sharp portions at both ends which are driven in the cap 25, and the corner metal 26, the palm metal 27 and the angle plate Numeral 28 is supported by screws or nails.

[0005] That is, the supporting portion, whether it is a sharp portion, a screw or a nail, at both ends of the cap 25 is a striated body, and the contact area with the column is a striated line in the axial direction of the column. Less. Therefore, when a load is applied, the filaments are thin and thin, so that the fiber of the column is broken and it is easy to move in the axial direction of the column. As a result, there is a problem that the support strength decreases or the support capacity is lost, and the reliability of the reinforcement is low.

[0006] In particular, as in the case of the conventional metal fittings 26, 27, and 28, those joined by screws (bolts) or nails from the outside of the pillar (wood) have a large variation due to the holding force. At present, there is a limit in the reinforcement of pipe columns, foundations and beams used for load-bearing walls, and there is a limit to increasing the wall magnification of load-bearing walls.

This invention has been proposed in order to solve such a problem, and the purpose is to support the load with a sheet-like body so that the wood fibers of the column are not easily broken and the shearing force is large. Another object of the present invention is to provide a column-reinforcement metal fitting that is strong against earthquakes and has high reliability in reinforcement.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the column reinforcing metal fitting of the present invention has a nut body or a bolt fixed to the base end side, a long hole is drilled in place, and a plate body inserted in the axial direction of the column, A wedge plate fitted into a long hole of the plate main body inserted in the axial direction of the column from a direction perpendicular to the axial direction of the column, and screwed to a nut or bolt of the plate main body, And a bolt or a nut that is fixed to the member to be mounted.

The plate body 1 has a nut 2 fixed at the center of the base end (lower end) side, and an elongated hole 3 formed in a horizontal direction above the plate body 1. Later, it is inserted in the axial direction from the bottom (end) surface of the pillar 8. The wedge plate 4 has an inclined surface 5 on at least one end side, and is inserted into the elongated hole 3 of the plate body 1 inserted in the axial direction of the column 8 in a direction perpendicular to the axial direction of the column from outside the column. It is to be inserted into. The bolt 6 is inserted from the back side (bottom side) 7 b of the base 7, which is an attached member, and is screwed into the nut 2 of the plate main body 1 erected on the upper surface 7 a of the base 7, and the plate main body 1 is 7 is fixed.

Next, a method of using the column reinforcing metal fitting 100 will be described with reference to FIGS. 2 and 3. FIG. First, the plate body 1 is erected on the upper surface of the base 7 which is a member to be attached. The bolt 6 is inserted from the lower surface (bottom side) of the base 7 toward the nut 2 of the plate body 1 and screwed together, and the plate body 1 is fixed to the base 7. When the bolt 6 is inserted into the base 7, a hole 10 is previously formed in the base 7, and the bolt 6 is screwed into the nut 2 through the hole 10.

Next, a column 8 is erected on the plate main body 1 fixed to the base 7 and erected. At this time, a hole 11 is bored in the column 8 from the bottom surface (end surface) in the axial direction, and the column 8 is inserted into the hole 11 and stands up by inserting the plate body 1.

Finally, the wedge plate 4 is fitted into the elongated hole 3 of the plate body 1 inserted in the axial direction of the standing column 8 in a direction perpendicular to the axial direction of the column 8 from outside the column 8. At this time, a hole 9 is formed in the column 8 toward a portion corresponding to the long hole 3 of the plate body 1, and the wedge plate 4 is fitted through the hole 9. When the wedge plate 4 is fitted, the pillar 8 is pushed down toward the base 7 by the inclined surface 5 at the tip end of the wedge plate 4 and comes into close contact therewith.

Next, a modified example of the present invention will be described. FIG. 4 is a cross-sectional view showing a modified example of the present invention. In this example, the plate body 1 is buried and erected in a base 7 which is a member to be attached, and the others are the same as in the above-described embodiment.
