Description

[Detailed explanation of the invention] (Industrial field of application) The invention is based on materials for wooden buildings, especially pillars.
This relates to connection fittings used for connecting beams, etc.

(Prior art) In the construction of wooden houses in Japan, there have been various methods for traditional joints and joints, and skilled carpenters carry out the labor-intensive woodwork for each house according to blueprints. , it was common for them to be built. Recently, construction materials and their connection structures have been unified and standardized, and the processing of joints and joints is intensively carried out in factories, and the processed materials are assembled with various connection fittings, dowels, etc. at the construction site. Attempts have begun to be made to easily construct wooden buildings using chisels.

(Problems to be solved by the invention) As mentioned above, building materials and their connection structures have been simplified and are now being carried out centrally in factories, but the processing of shiguchi, joints, etc. It was also a labor-intensive job, especially since the machined tenons had protruding parts at the end of the wood, and there was a risk of them breaking during storage or transportation, so it was necessary to handle them with great care. Also, battledore, tanzak,
Although it is possible to connect using metal objects such as boxes, it is possible to connect it in the ceiling or under the floor, but it has disadvantages such as the need to avoid connecting it in exposed areas. On July 6, 1985, we submitted an application for the registration of a utility model for materials for wooden buildings that are easy to assemble and do not require processing at the construction site, with the aim of simplifying the construction process. In other words, we have proposed a material in which a special insert with a bolt threading part on the head and a raised corkiscrew on the body is buried in the end of the wood for posts, stems, etc.; To prevent cracks from forming on thick square timbers such as tsukas, especially decorative pillars used in exposed areas indoors, the entire length of the sides of the timbers that are not exposed against walls etc. is split. In this case, it was found that embedding the insert would apply an expanding force to the back split, and the bonding strength between the insert and the lumber would be reduced.

The object of the present invention is to provide a connecting fitting with excellent connection strength, which can be used even with materials that have been subjected to back-splitting processing, such as columns.

(Means for solving the problem) In order to solve the problem, the present invention is based on a study of various types, and a metal plate bent at right angles in the shape of a light mountain section is attached to the nut into which the bolt is screwed. one end face,
This purpose can be achieved by using a connecting fitting that is fixed by welding or the like so that the piece is perpendicular to the outer surface of the nut, and a nail hole is drilled in the other side bent at right angles.

(Embodiment) The present invention will be described according to an embodiment shown in the drawings. As shown in FIGS. One piece 5 of the metal plate 3 bent at right angles in the shape of an angle iron is fixed at the end face by welding or the like so as to be perpendicular to the side surface, and a nail hole 7 is inserted into the other bent piece 6 of the metal plate 3.
This is a connection fitting 1 for drilling. The length of the long nut 2 used here is preferably long, but it may be short as in the other embodiment shown in FIG. 4, and may be cylindrical or prismatic. In addition, the piece 6 for drilling the nail hole 7 of the metal plate 3 is attached to the metal plate as shown in FIG. It is preferable that the distance 1 of the piece 6 of 3 from the axis of the long nut 2 is approximately equal to the radius of the column.

(Effects of the invention) Since the connecting fitting according to the present invention is constructed as described above, for example, as shown in FIG. Screw together in advance,
A pillar 9 having a back split 10 with a nut insertion hole drilled in the end according to the length of the long nut 2 is fitted with the connecting fitting 1, and the connecting fitting 1 is attached with a nail or a wood screw.
Using the nail hole 7 provided in the metal plate 3 of
Since it is only necessary to fix it to the pillar 9, it can be easily installed. Note that the thickness of the metal plate 3 of the connecting fitting 1 is preferably thinner than the width of the back split 10 provided on the pillar 9;
If it becomes thicker than the width of the paper, just widen the width of the back split. Furthermore, since the length of the column and the strength required of the column vary depending on the position of the column in the wooden building, the length of the long nut 2 of the connecting fitting 1 may be changed in accordance with the required connection strength.

By using the connecting fittings according to the present invention,
Even for columns with split backs, the connecting fittings are bent from the center of the pillar to the side of the column along the split, and fixed with wood screws, nails, etc. on the side of the column, so conventional connection methods are not possible. It is even more durable, and since it is tightly fixed to the foundation etc. with bolts, it is easy to assemble one piece at a time in an upright position without the need for horizontal connections or supports. When a wood screw or the like is screwed in from the wood end, it can be installed without fear of expanding the back crack.

The connecting fitting of the present invention can be devised for pillars with a split back, but it can be used widely even for ordinary unprocessed pillars by making a notch in the end of the pillar according to the shape of the connecting fitting. It is applicable.

Claims (1)

[Scope of utility model registration request] The end face of a piece 5 of the metal plate 3 bent at right angles in the shape of an angle iron is welded to the outer surface of the long nut 2 so as to be parallel to the axial direction of the long nut 2 and perpendicular to the outer surface. A connecting fitting for a wooden building, characterized in that a nail hole 7 is bored in the bent other piece 6 of the metal plate 3.
