Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for reinforcing a column connecting portion of a framed wooden house.

[0002]

[Prior art]

 Traditionally, wooden houses have been said to be relatively strong against earthquakes, but it was found that they were extremely vulnerable to severe earthquakes with a seismic intensity of 6 or more, or severe earthquakes, as was evident in the previous Great Hanshin Earthquake. The weight of the tile roof peculiar to a wooden house and the deterioration of the skeletons such as foundations, columns, and beams made it even easier to collapse a house, and it became the underlay of the collapsed house, resulting in many dead dead. However, framed wooden houses are suitable for the humid Japanese climate, and because of their attractive appearance, there is a strong demand for stand-alone houses.

[0003]

[Problems to be solved by the device]

 One of the reasons why the frame construction method is inferior in seismic resistance is that the column connection structure is mainly a combination of "tenon joint" and "kasugai". This is because the tenon part becomes weaker as it becomes thinner, and as the building ages, the tenon part becomes weaker due to corrosion, worming, etc.

[0004] Furthermore, a tree has considerable flexibility if it is long, but it is not flexible at a short portion such as a tenon, and when a large force is applied to that portion, it cannot bend and lose the force. It will be destroyed.

[0005] In addition, the braces are used to reinforce the tenon joints in order to withstand the force in the pulling direction, and are not a great reinforcement against the rolling of the house. Leading to destruction.

According to the present invention, a reinforcement connecting metal fitting is covered so as to cover a connection portion of a pillar, and the connection and connection portion of the pillar is reinforced by the metal fitting so as to supplement a pillar connection portion of a wooden house with improved earthquake resistance. It reveals a strong structure.

[0007]

[Means for solving the problem]

 The reinforcing structure of the column connecting portion of the wooden house of the present invention is a reinforcing structure of the column connecting portion of the frame wooden house in which the connecting portions of at least two columns orthogonal to each other are connected by the metal reinforcing connecting metal fittings. , Each reinforcing connecting metal fitting (2) is provided with at least two pillars (1) (11) which are orthogonal to each other by covering members (21) (21a) which are orthogonal to each other, and each covering member (21) (21a) ) Has a contact plate (22) (22) that is in contact with at least two side faces of the opposite pillar, and is a right-angled contact plate (22) on the outer surface of the covering member (21) (21a). A rib plate (4) is joined across the (22) and penetrates the post (1) and the contact plate (22) and is bolted.

[0008]

[Action and effect]

 The connecting portions of the pillars (1) and (11) orthogonal to each other are covered with the reinforcing connecting metal fittings (2), and the metal fittings and the pillars are fixed by tightening bolts, so that the connection between the pillars (1) and (11) is It is strong.

Further, the covering members (21) (21a) covering the columns (1) (11) have at least two contact plates (22) (22) which are orthogonal to the columns and have a right angle. A rib plate (4) is provided so as to straddle the covering member (21) (21a) forming the above. However, metal is more tenacious than wood, and has a larger Young's modulus and yield point than wood, and has a strong ability to restore its original shape.

Therefore, the reinforcing connecting metal fitting (2) can of course reinforce the connection portion of the pillar by the rigidity of the metal fitting itself, but even if a large momentary force acts on the connection portion of the pillar, The reinforcing connecting metal fittings (2) made of metal flex appropriately and return to the original shape immediately, so that the collapse of the house can be effectively prevented.

Except for custom-made pillars, the width standard has been decided, and the reinforcement connecting metal fittings (2) can be produced at the factory according to the standard of the pillar, and unlike the conventional tenon joint, it does not require on-site processing technology. In addition, the construction efficiency can be increased and the construction cost can be suppressed. In the following description, a pillar includes not only a vertical pillar but also a cross bar such as a beam and a base.

[Seventh Embodiment] FIG. 8 shows a reinforcing connecting metal fitting for connecting two orthogonal pillars. In the embodiment, in the same manner as in FIG. Two reinforcing fittings are used to connect the columns (1) and (12) horizontally and vertically, perpendicular to the horizontal columns.

The reinforcing connecting metal fitting (2) is formed by connecting two covering members (21) (21a) made of a channel material with a connecting plate (20) so as to form a right angle. The connecting plate (20) is connected to the end of the side plate (25) (25) of each covering member (21) (21a), and the groove bottom plates (26) of both covering members (21) (21a) are located on the same plane. There is.

Both side plates (25) (25) and the bottom plate (24) of the groove (23) of each covering member (21) (21a) are contact plates (22) that abut the pillars (1) (11).

The rib plate (4) is welded and fixed to the side plates (25) and (25) of both the covering members (21) and (21a), and the rib plate (4) is provided with a brace locking hole (41). It has been opened.

It should be noted that the holes for inserting the bolts in the pillars (1), (11) and (12) may be preliminarily processed before covering with the reinforcing connecting metal fitting (2) if the positional accuracy can be guaranteed. .

However, the connecting portions of the pillars orthogonal to each other are covered with the reinforcing connecting metal fittings (2), and the metal fittings and the pillars are fixed by tightening the bolts penetrating the metal fittings, so that the connection between the pillars is strong. .

The covering member (21) (21a) covering each pillar has at least two contact plates (22) (22) which are orthogonal to each other and has a right angle. A rib plate (4) is provided across the (21a) in parallel with a plane including the covering members (21) and (21a). However, compared to wood, metal is tenacious and has a strong ability to return to its original shape.

Therefore, the reinforcement connecting metal fitting (2) can of course reinforce the connection portion of the column by the rigidity of the metal fitting itself, but even if a large force is momentarily applied to the connection portion of the column, the reinforcement connection metal member (2) is reinforced. Since the connecting metal fitting (2) bends moderately and immediately returns to its original shape, the collapse of the house can be effectively prevented. Except for custom-made pillars, the width standard has been decided, and the reinforcement connecting metal fittings (2) can be factory-produced according to the standard of the pillar, and unlike the conventional tenon joint, there is no need for on-site processing technology. The construction efficiency can be increased and the construction cost can be suppressed.
