Description

[0001]
[Industrial applications]
The present invention relates to a column reinforcement device for an existing wooden house.
[0002]
[Prior art and problems]
There is no idea to reinforce the pillars of an existing wooden house.
[0003]
Therefore, even if it becomes necessary to reinforce the pillars alone in order to cope with an earthquake, etc., at least, a part of the house to which the pillars belong must be remodeled, and unnecessary burdens and construction time are reduced. I need it.
[0004]
The present invention has been made with the object of providing a device capable of reliably reinforcing a column with a simple structure.
[0005]
[Problems to be solved by the invention]
The first and second fastening brackets are respectively composed of a mounting piece and a fastening receiving piece, and the mounting piece of the first fastening bracket is a pillar of an existing wooden house that is erected on a foundation concrete via a base. An anchor for post-construction (as in the case of the basic concrete 5 of the embodiment), which is fastened to the outer surface of the base with a wood screw, and the mounting piece of the second fastening member is protruded from the outer surface of the basic concrete. , Which can be embedded and fixed at one end into an existing concrete structure, and the other end can be projected from the concrete structure, for example, a chemical rod. With the fixing nut, and a screw is provided between the tightening receiving portions of the first and second tightening receiving members through a through-hole provided in the tightening receiving portion, and a screw protruding from the through-hole is provided. A tightening nut is screwed to the tip.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Drawings show an embodiment of a pillar reinforcement device of an existing wooden house according to the present invention, FIG. 1 is a perspective view, FIG. 2 is an enlarged front view, FIG. 3 is a cross-sectional view of FIG. 2, and FIG. FIG. 5 is a perspective view, and FIG. 5 is an enlarged vertical sectional view of the second embodiment.
[0007]
The reinforcing device for pillars of an existing wooden house according to the present invention includes a second fastening device, on an outer surface 2 ′ of a pillar 2 of an existing wooden house, in which a first fastening member 1 is erected on a foundation concrete 5 via a base 4. The metal fittings 3 are fixed to the outer surface 5 'of the foundation concrete 5, respectively, and the tightening receiving pieces 6, 7 of the tightening metal fittings 1, 3 are provided with through holes 8 provided in the tightening receiving pieces 6, 7, respectively. , 8, a screw rod 9 is provided, and a tightening nut 10 is screwed to the tip of the screw rod 9 and tightened.
[0008]
The first fastening member 1 has the fastening member 6 provided with the through hole 8 at one end of one side (outer surface) of the strip-shaped attachment portion 11, and the attachment portion 11 has a wood screw. Through holes 13, 13, 13 are arranged in a row so as to penetrate the column 12, the mounting piece 11 is overlapped on the outer surface 2 ′ of the column 2, and the wood screw 12 is embedded in the column 2 through the through hole 13 (screw). And fixed to the pillar 2.
[0009]
Although the first fastening member 1 of the embodiment is formed of a so-called hole-down metal member, it is not necessary to limit the structure to the structure of the embodiment. , Or a nail).
[0010]
The second fastening member 3 is formed by welding both ends of a metal piece bent in a U-shape to an intermediate portion of one surface (outer surface) of an elongated plate-shaped mounting portion piece 14 to provide the fastening receiving piece 7. Then, the mounting piece 14 is superimposed on the outer surface 5 'so that the screw rod 15 protruding from the outer surface 5' of the foundation concrete 5 is inserted, and a fixing nut 16 is screwed onto the screw rod 15. It is tightened.
[0011]
The threaded rod 9 is provided with a through hole 8 in each of the fastening member 6 of the first fastening member 1 fixed to the column 2 and the fastening member 7 of the second fastening member 3 fixed to the foundation concrete 5. , 8 through which a fastening nut 10 is screwed to a tip (end) protruding from the through hole 8.
[0012]
The screw rod 9 of the embodiment is constituted by a so-called rod rod provided with screws at both ends. However, the screw rod 9 is constituted by a bolt rod so that the head is engaged with the tightening portion 6 on the first tightening member 1 side. Nevertheless, there is no structural disadvantage. However, if it is constituted by a bolt rod, the bolt-shaped screw rod (bolt rod) requires a complicated operation of penetrating the through holes 8, 8 from the tightening receiving portion 7 side of the second tightening metal fitting 3, so that the actual operation is complicated. The upper portion extends from the first tightening receiving portion 1 side to the tightening receiving portions 6 and 7, and as a result, the tightening nut 10 is attached to the tip of the second tightening receiving member 3 projecting from the tightening receiving portion 7. It has to be screwed and tightened, that is, the tightening operation must be performed at a low position, and the operation is complicated. The screw rod 9 of the embodiment can avoid this (the tightening nut 10 may be simply screwed into one tightening receiving piece 7 side of the screw rod 9).
[0013]
The reason why the tightening portion 7 of the second tightening member 3 is biased to one end of the mounting portion 14 along the longitudinal direction is to avoid interference of the screw rod 15.
[0014]
The screw rod 15 of the embodiment may have any structure as long as it can be fixed to the existing foundation concrete 5 and the screw portion can be protruded from the concrete outer surface 5 '.
[0015]
In the first embodiment shown in FIGS. 1 to 3, when the foundation concrete 5 omits a reinforcing bar, that is, a stainless steel plate 17 is superimposed on the outer surface of the concrete 5 on a plain concrete cloth foundation, and Anchor 18 for post-processing and nuts 19 screwed thereto are tightened to reinforce the foundation concrete 5, and some of the anchors 18,... And nuts 19 used for the reinforcement are denoted by reference numeral 15. , 16, a screw rod 15 and a fixed nut 16 are provided.
[0016]
The second embodiment shown in FIGS. 5 and 6 shows a case in which a foundation concrete 5 that does not require reinforcement as in the first embodiment is used.
[0017]
In each of the first and second embodiments, the first fastening member 1 is fixed to the column 2 through the outer wall 20. However, the metal member 1 may be fixed directly to the column 2 as a matter of course. It is.
[0018]
In the drawing, reference numeral 21 denotes a drainer. The reason why the tightening receiving parts 6, 7 are considerably protruded from the mounting part pieces 11, 14 is that the tightening operation of the nuts 10, 16 can be performed smoothly and this drainer 21 is provided. This is also to avoid interference.
[0019]
【The invention's effect】
Since the present invention is configured as described above, it is possible to easily reinforce columns without damaging existing wooden houses (outer walls and structural members).
