Embodiments of the present invention will be described below in detail with reference to the drawings illustrating embodiments of the present invention. FIG. 1 shows an embodiment of a shaft set in which braces are arranged on both sides of a lower end portion of a pipe column erected on a base. As shown in FIG. 1, a pipe column 6 is erected on a base 2 with a pedestal plate 4 therebetween. The pedestal plate 4 is made of a rectangular steel plate as shown in FIG. 2 (a), and has a rectangular length in the center so as not to hinder the insertion of the tenon at the lower end of the tube column 6 into the tenon of the base 2. It is a member in which a hole 8 is formed, and is attached to the base 2. The pillar 6 is erected with a tenon provided at the lower end thereof fitted into a tenon hole of the base 2.
L on both ends of the pedestal plate 4 protruding from both sides of
The character fitting 10 is arranged. The L-shaped bracket 10 is shown in FIG.
As shown in (b), a steel plate having a predetermined width is bent at a right angle to form a bottom surface portion 12 and an upright surface portion 14. The bottom surface portion 12 is on the upper surface portion of the pedestal plate 4, and the upright surface portion 14 is It is attached so as to be in contact with the side surface of the tube post 6.

Further, a bracing bracket 16 is mounted on both L-shaped brackets 10. The bracing bracket 16 is shown in FIG.
As shown in (c), it is a member made of a steel plate having a bottom surface portion 18, a side surface portion 20, and an upright surface portion 22 which are at right angles to each other, and the bottom surface portion 18 and the side surface portion 20 are respectively L-shaped fittings 1.
The bottom surface portion 12 and the upright surface portion 14 are overlapped and attached. Brace 24 and 26 are attached to the outside of the upright surface 22 of each brace 16, respectively, and the column 6 is tightened by a pair of hole-down fittings 28 arranged on both sides thereof. It is firmly attached to the base 2. The hole-down fitting 28 is shown in FIG.
As shown in FIG. 3, the pulling bolt 30 and a pulling fitting 32 capable of engaging the pulling bolt 30 are provided.
2 is a bolt hole for bolting itself to the tube post 3
3 and a bolt engaging part 3 provided with a through hole for a tension bolt 30 at a position at a predetermined height from the mounting part 34.
6. In this embodiment, the pulling fitting 32 is used.
The press-formed steel plate is used, but its thickness, shape and the like are determined so as to secure sufficient strength.

A pair of hole-down fittings 28 arranged on both sides of the tube post 2 are mounted by tightening bolts 40 inserted into through holes penetrating the tube post 6, and bolts of the pull-down fitting 32 at both ends. It is passed through the hole 33 and tightened with a bolt, so that it is firmly fixed. Both hole down fittings 2
The tension bolt 30 of No. 8 has a washer 42 fitted on the head side, is inserted into a through hole penetrating the base 2 from the lower surface side of the base, and an end passed through the bolt hole of the bolt engaging portion 36 is Tightened with nuts. As a result, the column 6 is firmly attached to the base 2 and joined. The vicinity of the head of the tension bolt 30 on the lower surface side of the base 2 is slightly counterbore. The installation of the tension bolt 30 is shown in FIG.
The direction is opposite to that shown in FIG.

As shown in FIGS. 2A to 2C, the pedestal plate 4, the L-shaped bracket 10, and the bracing bracket 16 are provided with long holes 44, 46, and 48, respectively.
0 is not hindered. Braces 24 and 26 have a cross-sectional dimension of a thickness of 1/2 to 1 of tube column 6.
３, the width of which is about the same as or slightly smaller than that of the tube post 6, and the tip has a sharp angle with a narrow angle of about 90 degrees, and both end faces of the tip are L-shaped. It is configured to come into contact with the inner surface of the metal fitting 10. A screw nail is used to attach a connection fitting such as the pedestal plate 4, the L-shaped fitting 10, the bracing fitting 16 to the base, the pipe column, the bracing, etc., and the screw nail hole 50 provided in each member is shown in FIG. ) And (b) are formed in a truncated cone shape.

As the screw nail, for example, a screw having a diameter of about 5 mm and a pitch of about 3.5 mm is used. The depth of the thread valley is about 0.8 mm. Can enter the valley portion of the screw, so on both sides of the screw, the base plate 4 and the L-shaped bracket 1 are doubled by about 1.6 mm.
0, the movement adjustment of the bracing fitting 16 becomes possible. That is, assuming that δ is the deflection of the inner hole of the screw nail hole 50 when the corner of the inner hole contacts the valley portion of the screw nail 51, the total movement amount is 2δ.
Becomes

Normally, the screw hole is a straight hole except for the portion where the screw head directly contacts, and a predetermined gap is usually provided between the screw outer diameter and the screw hole. In this case, as described above, since the conical shape is used, there is an advantage that the movement adjustment range of each member such as the pedestal plate can be increased even if the gap is the same. When the L-shaped bracket 10 is superimposed on the pedestal plate 4 or the bracing bracket 16 is further superimposed thereon and attached, a screw nail is inserted into a screw hole provided at the same relational position of each member, and each screw is screwed. The members are attached integrally.

For example, when the L-shaped bracket 10 is mounted on the pedestal plate 4 in an overlapping manner, the L-shaped bracket 10 is attached to the upright portion 1 thereof.
4 is placed on the pedestal plate 4 in a state where the
Screw holes are provided at the same position on the metal fitting 10 and the pedestal plate 4 and then screwed in. Then, the screw nails are inserted and attached integrally. Since the portion 14 does not come into contact with the tube post 6 and a gap may be formed and a strong attachment may not be possible, it is necessary to finely adjust a relative attachment position between the members. In such a case, as shown in FIG. 3 (c), each screw nail hole 50 is dished into a truncated cone, so that it can be moved and adjusted in the horizontal direction as compared with a normal straight screw nail hole. There is an advantage that the range can be widened. That is, since the tip of the inner hole of the screw hole 51 can enter the valley of the screw nail 50, the adjustment range becomes large. Since the tip of the inner hole of the screw nail hole 50 can enter the valley of the screw nail 51, the adjustment range becomes large. The adjustment may be performed by loosening the screw 51, moving and adjusting each member within a range of the screw hole and the clearance of the screw, and then tightening the screw. The same applies to the case where the bracing fitting 16 is further mounted on the L-shaped fitting 10.

In the embodiment configured as described above,
For example, when a horizontal force is applied to the pipe column 6 rightward due to an earthquake, a typhoon, or the like, the other ends of the braces 24 and 26 are connected to the pipe column 6.
Since it is connected to the upper horizontal member and the like, a tensile force is applied to the braces 24 and a compressive force is applied to the braces 26 (if the force applied to the pipe column 6 is reversed, the tensile force, The compression force is also reversed), but the ends of the braces 24, 26 are
And the bracing bracket 16 is the L-shaped bracket 1
0, since it is fixed to the tube column 6 and the base 2 via the pedestal plate 4, the resistance to the tensile force and the compressive force is increased, and deformation and breakage are unlikely. In addition, a pedestal plate 4, an L-shaped bracket 10,
Since the metal members such as the bracing fitting 16 are arranged, deformation or breakage caused by the end of the pillar or the bracing biting into the base or the waist is less likely to occur. Further, the hole-down fitting 28 for tightening and fixing the pipe post 6 to the base 2 is provided with the pull-down fitting 3 with which the tension bolt 30 is engaged.
0 is firmly fixed to the column 6 by a fastening bolt 40 penetrating the column 6, and an L-shaped metal fitting 10 that contacts the side surface of the column 6 and the upper surface of the base 2 is provided on both lower ends of the column 6. Since the tube column 6 is attached, it is difficult for the column 6 to be detached from the base 2 or to be distorted in the direction in which the column 6 falls. The bracing bracket 16 mounted on the L-shaped bracket 16 has a raised surface 22 that acts as a rib between the bottom surface 12 and the raised surface 14 of the bracing metal 16, and the pipe column 6 falls down. Helps reduce directional distortion. Therefore, as a result of these actions being weighted, the strength of the wall is greatly improved.

08, but the pedestal plate 4 and the L-shaped fitting 1 of the same type as used in
0, a bracing bracket 16 is used. In this experimental example, a steel plate having a thickness of 3.5 mm and a dimension shown in FIG. 8 was used. When a test was performed using the above-described test body (wooden load-bearing wall) by a predetermined method, the wall magnification was 6.3. By the way, the wall magnification is determined for each type of wall by the Building Standard Law Enforcement Ordinance and the Ministry of Construction's notice. In case of split 1.
5, 2.0 for columns and 3.0 for columns of the same size. By the way, in the above-mentioned test body, the wall magnification is three times or more of the standard 2.0 in the case of the above-mentioned split, and the strength of the wall is remarkably large although the bracing 108 is smaller than the split of the pillar. It was proved.

It is.

[0021]

Since the present invention is configured as described above, the following effects can be obtained. Since the metal base plate, L-shaped bracket and braced bracket are arranged around the braced end, the braced works well, the wall magnification of the load-bearing wall increases dramatically, and the strength of the wall increases. improves. The reason is not always clear, but is interpreted as follows. In other words, a metal pedestal plate is attached to the horizontal member or base where the ends of the braces are in contact,
A metal L-shaped fitting is attached in contact with the side surface of the pedestal plate and the column, and a brace fitting is further mounted on the L-shaped fitting, and the end of the brace is attached by the brace fitting. When compressive force is applied to the brace by applying horizontal force to the pillar, the end of the brace is firmly received by the metal brace, L-shaped fitting, and pedestal plate. The end of the brace is prevented by the above-mentioned brace fittings and the like, when damage or deformation of the brace end and its surrounding pillars, base, horizontal members, etc. are prevented, and when the brace is subjected to tensile force, It is considered that the original function of the strut can be exhibited as a result of preventing the strut end and its surrounding members from being damaged at the same time as being stopped against the tensile force.
When the pedestal plate, the L-shaped bracket, and the bracing bracket are integrally formed, if there is a dimensional error in the pillar, the base, the horizontal member, etc., a gap is generated between the above-described parts and the pillar, and the like. Although it is considered that the above-described effects cannot be obtained, in the present invention, since each part is separately formed, by finely adjusting the mounting position, the above-mentioned parts are put in a state where there is no gap between the pillar, the base, It can be attached to a horizontal member, and the above-described effects can be obtained. Also, hole-down fittings and the like are used for connecting the pillar and the base or the pillar and the horizontal member,
It is thought to be somewhat useful for improving the wall magnification, although it is constructed to be sturdy and can be mounted firmly by means of fastening bolts penetrating the column. Each of the above members is attached by piercing a screw hole for attaching a pedestal plate, an L-shaped metal fitting, and a bracing metal into a conical shape and sharpening an inner end portion of the nail hole so as to be able to enter a screw valley of the screw. The advantage is that the time adjustment range is large.
