Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column base joining apparatus and method for a wooden column member, and more particularly, to an installation adjustment of a column member.

[0002]

2. Description of the Related Art Conventionally, when joining a column base of a wooden column member to a concrete foundation, the end face of the column base that is formed flat and the upper end face of the foundation concrete that is formed horizontally are brought into contact with each other in a plane contact. After that, the joint was formed using, for example, a metal bolt or a metal plate. Generally, it is relatively easy to secure the flatness of the end face of the column base of the wooden column member, but it is difficult to secure the flatness of the upper end face of the foundation concrete. Therefore, when the pillar member is placed on the upper end surface of the foundation concrete, the axis of the pillar member tends to be inclined with respect to a desired direction (generally, the vertical direction). This inclination must be corrected in advance when joining the two members.

[0003]

As described above, in the conventional column base joining apparatus and method for wooden column members,
The end face of the column base and the top face of the foundation concrete are in plane contact. Therefore, there is an inconvenience that it is difficult to slightly adjust the building (adjust the axial direction of the pillar member in a predetermined direction) and slightly adjust the level (adjust the position of the pillar member along the axial direction). .

Particularly, in the column base joining method recently proposed, unlike the conventional column base joining method that allows so-called backlash, the column member is almost rigidly joined to the base member. In this case, if rigid connection is performed without adequately adjusting the installation or level of the column member, there is the inconvenience that the installation error of the column base adversely affects other member connection parts.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a column base joining apparatus and method capable of adjusting the construction of wooden column members. It is another object of the present invention to provide a column base joining apparatus and method that allow level adjustment as well as placement adjustment.

[0006]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram schematically showing the configuration of a column base joining apparatus according to the first embodiment of the present invention. The device shown is
It is provided with a plurality of reinforcing bars 2 embedded in a pillar member 1. The reinforcing bars 2 are preferably four deformed reinforcing bars arranged at positions corresponding to the four corners of a square, for example, and are fixed to the column member 1 with an adhesive.

Further, in the concrete foundation member 3 to which the column member 1 is to be joined, four holes 4 are formed at positions corresponding to the above-mentioned reinforcing bars 2. Each hole 4 has a corresponding deformed bar 2
In the inserted state, a filler 5 such as non-shrink mortar is injected. Further, a projecting portion 7 is formed at the center of the column base end surface 8 of the column member, and a recess 8 is formed at a corresponding position on the upper end surface 9 of the base member 3. Note that, in FIG. 1, for the sake of clarity of the drawing, the pillar member 1 and the base member 3 are illustrated as being separated by a certain distance, but in reality, this distance is as small as possible. Is configured as follows.

2 and 3 are diagrams showing the structures of the projecting portion 7 and the recessed portion 8 in detail, respectively. In FIG.
The protrusion 7 comprises a plate 21 fixed to the column base end face 6 of the column member 1 by suitable fastening means such as self-tapping screws 22. The plate 21 is preferably made of metal, and the female screw 2 is provided at a substantially central portion thereof.
6 is engraved.

A bolt member consisting of a head 23 having a spherical surface convex downward in the drawing and a male screw portion 25 is screwed into a female screw 26 formed on the plate 21 via a washer 24. On the other hand, in FIG. 3, the recess 8 is provided with a receiving member 32 made of, for example, a metal, which is embedded in a cylindrical hole 31 formed in the concrete foundation 3. As shown in the figure, the upper surface of the receiving member 32 has a spherical shape that is convex downward in the figure. In this way, the receiving member 32 is configured to make spherical contact with the head 23. It is preferable that the surface of the concave spherical surface 33 of the receiving member 32 be made of a material having a small frictional resistance (for example, Teflon) to reduce the swing resistance.

A column base joining method according to the first embodiment of the present invention constructed as above will be described. The projecting portion 7 formed on the column base end surface 6 of the column member 1 is placed in contact with the concave portion 8 formed on the upper end surface of the concrete foundation by spherical contact. In this state, each of the deformed reinforcing bars 2 protruding from the column member 1 is inserted into the corresponding reinforcing bar insertion hole 4 of the foundation 3. Further, by accurately performing the positioning of the projecting portion 7 and the recessed portion 8 respectively in advance, it becomes possible to accurately perform the positioning of the column member in the horizontal plane only by engaging the projecting portion 7 with the recessed portion 8 when building. .

Next, the installation of the swingable column member 1 is adjusted to a desired position while measuring with an appropriate optical device or the like. Further, if necessary, by rotating the head 23, the protrusion 7 can be appropriately expanded and contracted in the axial direction of the pillar member 1 to adjust the level of the pillar member 1. At this time, the washer 24 may be used for height adjustment. While the pillar member 1 is held at the desired position by the erection member, the reinforcing bar insertion hole 4 of the foundation 3 is filled with, for example, non-shrink mortar 5. The rigid member is removed until the non-shrink mortar 5 is solidified until it reaches a predetermined strength, and the rigid connection of the column base is completed.
