Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention mainly applies to the connecting part between the foundation and columns (column tenon and foundation) in wooden buildings. (mortise part) to prevent the column part of the foundation from being compressed due to fixed load or live load. Related to auxiliary fittings for wooden constructions that prevent them from forming or buckling. It is.

0002

[Conventional technology]

In wooden buildings, the method of connecting the foundation and columns is generally done by connecting the foundation to the foundation as a conventional construction method. The old method of fitting the tenon at the bottom end of the pillar into the mortise hole and connecting it as one piece is an old method. It has been adopted since then.

[Problem that the idea aims to solve]

By the way, in wooden buildings, the foundation is the essential part that supports the house, and it does not rot. Since ancient times, the foundation has been made of cypress with a core. It is said to use wood. However, due to rising land prices and rising prices of construction materials, etc. Due to the significant increase in housing prices, expensive materials such as cypress are being used for foundations. Recently, rice hemlock wood, which grows better and has fewer annual rings than inland wood, is being used as an injected material ( Products injected with anti-termite materials and preservatives are useful because they are cheap, lightweight, and easy to work with. As a result of being widely used in pre-built houses, etc., the load (the weight of the building itself) is reduced at the column support part. To receive concentrated loads such as easy fixed loads, live loads of tatami mats, furniture, etc., snow loads, etc.) The incidence of compressive deformation and buckling in the foundation is noticeably increasing. Especially for three-story wooden buildings. Since construction was permitted, the fixed and live loads on the foundation have increased and there has been a strong tendency for this to occur. It has become. With conventional construction methods, there are spans of 2.73m, 3.64m, etc. between columns. Columns are susceptible to concentrated loads, and holes such as mortises or other The strength of the soil is weakened due to the use of grooves such as dovetail grooves. Buckling of the stand is particularly large. The same applies when using cypress wood etc. for the base. Ru. Once the foundation buckles, etc., the columns will gradually fall downward and damage various parts of the building. Not only will this cause distortion and distortion, but the sills, etc. connected between the pillars will curve upward. This prevents the smooth movement of doors, shoji screens, doors, etc. Also, partially If buckling occurs, even if you try to repair it by lifting only the buckled part, it will be a mistake. The pillar part is integrally connected and reinforced with other parts, so partial lifting, etc. is extremely difficult to repair.

[Means to solve the problem]

The present invention was devised in view of the above-mentioned actual situation, and is intended for use with nails, bolts, etc. Provide multiple insertion holes, and cut into the protruding end of the top piece each into which the tenon of the pillar fits. Form a pair of left and right U-shaped spacers with cutout grooves, and insert the spacers into the tenons of the base. Insert it into the hole formed part from both the left and right sides, and securely hold the base around the entire circumference and slide it. The gist of this is that the spacer is interposed between the joint surface of the foundation and the column. Ru.

[0005]

[Effect]

Insert the U-shaped spacer from both the left and right sides of the base, aligning the notch with the mortise. After inserting the spacer and fixing the top piece of the spacer to the base with nails, etc., insert the tenon of the column into the mortise of the base. Insert the spacer into the spacer and drive a nail, etc. through the side piece of the spacer to fix the tenon. This allows the base The upper side of the spacer is interposed between the joint surface of the column and the column, and the spacer is connected to the column of the foundation. It is integrated with the foundation while holding the part around almost the entire circumference, and the concrete The bottom piece of the spacer will also be interposed on the joint surface of the cloth foundation and the column, so the column cannot be passed through. The fixed load and live load applied to the foundation will be absorbed by the spacer. Become. Therefore, the column connecting part of the foundation becomes extremely strong, and the foundation part compresses due to the load. Deformation and buckling are prevented.
