Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for a longitudinal frame member such as a column, a stud, or a frame, which is vertically installed with its upper end supported and fixed by a lateral frame member such as a beam.
[0002]
[Prior art and problems to be solved by the invention]
For example, in the case of wooden buildings using the conventional frame construction method or two-by-four construction method, the horizontal direction installed in the lateral direction such as beams, foundations, window sills, lintels, head joints, etc. The frame members and the vertical frame members installed in the vertical direction, such as columns, studs, and eaves frames, are integrated by assembling these ends at a right angle or a predetermined angle, and reinforcement such as bracing The materials will be installed as appropriate to make the frame structure of the wooden building.
[0003]
And various joints are known as the structure of the joint part for fixing and joining and integrating the ends of the frame members such as the transverse frame members and the longitudinal frame members to the other frame members. In particular, it is common to employ a tenon joint structure as a joint for joining the upper end portion of the longitudinal frame member to the lateral frame member. For example, as shown in FIG. 7 and FIGS. 8A to 8C, the joint structure with tenons has a quadrangular cross-section projection (tenon) 50 protruding from the upper end surface on the upper end surface of the longitudinal frame member 53. The tenon 50 is inserted and locked in a tenon hole 52 having a cross-sectional shape substantially matching the tenon 50 formed on the lower surface of the transverse frame member 51 such as a beam, and the vertical frame member 53 is arranged upright. After that, a fixing member such as a fixing nail 54 is driven into the joint portion into which the tenon 50 is inserted, and the upper end portion of the longitudinal frame member 53 is fixed to the lower side portion of the lateral frame member 51.
[0004]
However, according to the conventional joint structure using a tenon, the work of the tenon 50 and the tenon hole 52 is troublesome, and the workability when attaching the longitudinal frame member 53 is poor. That is, in order to project and form the tenon 50 having a substantially box-shaped hexahedron shape from the upper end surface of the longitudinal frame member 53, it is necessary to process and form a plurality of surfaces connected at right angles with high accuracy. In order to form the mortise 52 having the shape on the lower surface of the lateral frame member 51 with high accuracy, a high level of skill is required. And when these processing precisions are inferior, it becomes difficult to insert the tenon 50 into the tenon hole 52, or a gap of a considerable size is generated around the tenon 50 inserted into the tenon hole 52. It becomes easy to produce looseness in the part.
[0005]
Further, since the mortise 52 is formed by hollowing out the lower surface of the lateral frame member 51, the mortise 50 can be inserted and locked only from the lower side of the mortise 52, and is disposed above. Since the space between the lateral frame member 51 and the floor base plate 56 disposed below is generally only the height of the vertical frame member 53, the vertical frame member 53 is erected. Installation work becomes difficult. As shown in FIG. 9, a method of forming a notch 55 in the lower surface of the lateral frame member 51 in place of the mortise 52 is adopted so that the tenon 50 can be slid and locked from the side. However, since a cross-sectional defect is generated on the lower end side of the lateral frame member 51 to which the tensile force acts, a problem in strength occurs.
[0006]
The present invention has been made paying attention to such a conventional problem, and can reduce the labor of processing for the joint structure by the tenon and supports and fixes the upper end portion of the longitudinal frame member to the lateral frame member. An object of the present invention is to provide a mounting structure for a longitudinal frame member that can improve the workability at the time.
