Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connection structure between a pillar and a horizontal member in a wooden building.

[0002]

[Prior art]

 Conventionally, in a wooden building, columns are connected to horizontal members such as foundations, beams and eaves girders by forming tenons 2 at the upper and lower ends of the columns 1 as shown in FIGS. It is carried out by fitting it into a mortise 4 formed in the horizontal member 3 and fastening the pillar 1 and the horizontal member 3 with a reinforcing metal fitting 5. Reference numeral 6 is a nail for fixing the reinforcing metal fitting 5 to the pillar 1 and the horizontal member 3.

[0003]

[Problems to be solved by the device]

 However, the connection between the pillar 1 and the horizontal member 3 having the above-described structure is performed by fitting the tenon 2 of the pillar 1 and the mortise hole 4 of the horizontal member 3, so that the horizontal member 3 can be easily fitted. If the mortise 4 is made larger than the mortise 2, rattling occurs between the column 1 and the horizontal member 3, resulting in an unstable structure as a frame structure. Therefore, it is necessary to fit the mortise 2 into the mortise hole 4 without any gap, and in this case, the external force is applied by hitting with a hammer or the like. As a result, it is difficult to assemble the pillars 1 and the horizontal members 3 at a factory or the like, and it is difficult to easily assemble the pillars 1 and the horizontal members 3 at a construction site. Further, it is necessary to prepare a reinforcing metal fitting 5 for connecting the pillar 1 and the horizontal member 3 and to drive a large number of nails 6 to fix the reinforcing metal member 5 to the pillar 1 and the horizontal material 3. There was a problem that it took time to work.

The present invention solves such a problem, and an object thereof is to make it possible to easily connect a column and a horizontal member, and also to enable prefabrication.

[0005]

[Means for Solving the Problems]

 In order to solve this problem, the present invention provides a connection structure of a lower end or an upper end of a pillar in a wooden building and a horizontal member such as a base or a beam that abuts on the lower end or the upper end. An upper constricted recess is formed on the lower surface of the horizontal member to be placed on the pillar, and the upper and lower surfaces of the horizontal member at the position where the pillar is placed are smaller than the inner width dimension of the lower end of the recessed portion, A recess with the same inner width in the same direction is formed, and it is formed on the lower end surface of the column or on the lower surface of the horizontal member mounted on the column and on the upper surface of the horizontal member or the upper end surface of the column at the position where the column is mounted. A connecting member having half the same shape as these recesses is fitted into the recessed portion, and the outer width dimension of the upper half portion of the connecting member is formed on the lower end surface of the column or the lower surface of the horizontal member mounted on the column. The outer width of the lower half matches the inner width of the recess The method is such that the lower half part has a margin smaller than the inner width dimension of this recess so that there is play when it is fitted in the recess formed in the upper surface of the horizontal member or the upper end surface of the column at the position where the pillar rests. After confirming that the through holes provided in the horizontal direction at the upper and lower ends of the connecting member match the pin insertion holes formed in the horizontal members and columns, insert the pins into the through holes from the pin insertion holes. The gist is that the horizontal members and columns are fastened together.

[0006]

[Action]

 With this configuration, the recess formed on the lower end surface of the column or on the lower surface of the horizontal member that rests on the column has a slope.Therefore, by inserting the connecting member into this recess, the position of the column and the horizontal member may be slightly different. Positioning can be performed by absorbing the deviation. Also, the outer width dimension of the lower half portion of the connecting member is such that there is play when the lower half portion is fitted into a concave portion formed on the upper surface of the horizontal member or the upper end surface of the column at the position where the column is placed. Since it is set to be smaller than the inner width dimension of the column with a margin, this can also absorb the dimensional error of the connecting portion between the column and the horizontal member. Therefore, it is no longer necessary to hit the tenon with a hammer to fit the tenon into the mortise as in the past, and the pillar and horizontal members can be unitized at a factory or the like to simplify the pillar and horizontal members at the construction site. It can be assembled and can be prefabricated. In addition, there is no need for reinforcing metal fittings to connect the pillars and horizontal members, and it is not necessary to hammer in a large number of nails to fix the reinforcing metal fittings to the pillars and horizontal members, simplifying assembly. Can be converted.
