Description

  The present invention relates to an apparatus for joining columns in a wooden building, in which a column base is interposed between the column and the foundation concrete in order to directly fix the column of the wooden building to the foundation concrete.

  An anchor bolt projecting from the foundation concrete and a nut screwed to the tip of the anchor bolt are used to fasten the hardware body to the foundation concrete, and a connection plate is erected on a receiving plate provided on the hardware body. There is a structure that is inserted into a pillar placed on the receiving plate and fixed with a drift pin (for example, Patent Document 1). In this conventional example, a hardware body is fastened to basic concrete with anchor bolts and nuts, A connecting plate protruding from a receiving plate at the upper end of the main body is inserted into a slit provided on the lower surface, and a column is placed on the receiving plate to be used upright.

JP 2002-167868 A

  In the conventional structure, when connecting the column to the connecting plate, the connecting plate is assembled so that the connecting plate is inserted into the slit provided on the column side, but there is no special mark. The unloading operation is complicated. In addition, it is desirable to perform slit forming work in the field in order to correspond to the situation in the field, but processing to make a straight edge shape at the back end of the slit using a circular saw that matches the straight edge shape of the tip (upper end) of the connection plate It requires skill and skill, and is actually a processing work in the factory.

  This invention pays attention to the fault of such a prior art example, and created it in order to provide the joining apparatus of the pillar in the wooden building which can aim at the workability | operativity of construction on the spot.

  A main body frame that is fastened to the foundation concrete by an anchor bolt and a nut that is screwed to the anchor bolt, and the pillar that is erected on the main body frame and that is fitted into a slit provided on a lower surface of the pillar that is erected on the main body frame. A connection plate for fastening the connection plate, a substantially V-shaped notch provided in the center of the upper end of the connection plate, and the rear wall of the slit engaged with the center portion of the notch being substantially V-shaped in front view. .

  According to the present invention, when assembling the column to the connection piece on the main body frame fixed on the foundation concrete with the anchor bolt, the notch provided on the connection piece side is provided with the V-shaped back wall of the slit provided on the column side. The column portion constituting the central portion can be engaged to expect a positioning function for the connecting piece of the column. Therefore, labor saving of the assembling work for the connecting piece of the column can be achieved.

  Moreover, since the slit whose V-shaped wall is formed on the column can be easily formed by a so-called circular saw, the column can be improved in workability without inconvenience in field construction even if the labor saving is expected. Can be provided.

  The drawings show an embodiment of a column joining apparatus in a wooden building of the present invention. A column base metal A of the embodiment includes a main body frame 1 and a connection plate 2 erected on a receiving plate 3a of the main body frame 1. Consists of.

  The main body frame 1 has a pair of leg plates 3c and 3c which are erected on the upper surface of a square substrate 3b having an assembly hole 4 in the center, with the assembly hole 4 interposed therebetween, and the leg plates 3c and 3c. The receiving plate 3a is placed and fixed so as to pass through, and the receiving plate 3a, the substrate 3b, and the leg plate 3c are welded together to form the main body frame 1.

  The connecting plate 2 is a vertically long rectangular plate having a width that fits within the diameter of the column 101, and has a V-shaped configuration in which the opposite side edges 5a and 5a form a gentle arc shape at the center of the upper end. A notch 5 is provided, and a square piece 2a is provided in a tongue shape at the center of the lower end.

  A long hole 6 is provided in the center of the receiving plate 3a of the main body frame 1 in a direction in which the leg plates 3c and 3c face each other, and the piece 2a of the connecting plate 2 is passed through the long hole 6 so that the leg plate 3c, The connecting plate 2 is erected on the receiving plate 3a of the main body frame 1 to be a column base metal A.

  This column base metal A is engaged with the anchor bolt 21 protruding from the foundation concrete 102 in the assembly hole 4 (so that the anchor bolt 21 penetrates the assembly hole 4), and the anchor bolt 21 is connected to the substrate 3b. The nuts 22 are screwed together and fastened to the ends of the anchor bolts 21 protruding from the assembly holes 4 (substrate 3b), and fixed to the foundation concrete 102.

  The column 101 was placed on the receiving plate 3 a so that the connection plate 2 of the metal object A was engaged with the slit 7 provided at the lower end, and provided in the through hole 23 provided in the column 101 and the connection plate 2. The column 101 is supported and fixed to the column base metal A by passing the connection bolt 25 through the through hole 24 and screwing the nut 26 to the tip of the bolt 25.

  The slit 7 provided in the column 101 is formed with a circular groove s on one side along the vertical (longitudinal) direction of the column 101 to form a cutting groove (upper edge is arcuate), and then on the other side opposite to the one side. By cutting the back end side of the one-side cutting groove with a circular saw s, the back wall 7a is formed to have a substantially V shape when viewed from the front, and the center V-shaped bottom portion 7a 'formed by the back wall 7a is formed. Is engaged with the notch 5 and guided there, so that the connecting work of the connecting plate 2 and the slit 7 erected on the foundation concrete 102 is performed relatively smoothly.
