Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden cantilever type carport, and more particularly to a support structure for a roof portion of a wooden cantilever type carport.

[0002]

2. Description of the Related Art When a relatively small carport is installed, a cantilever type carport is often used in which a support is provided only on one widthwise end of the roof. Such a cantilever type carport is usually made of a metallic material.

[0003]

However, metal carports are often lacking in luxury, and users who want to give a carport a luxury look by configuring the cantilever carport as a wooden one. Is relatively large.

However, in the cantilever type carport made of wood, it is necessary to use a metal connecting plate for the connection portion in order to secure sufficient anti-rotation strength at the connection portion between the support pillar and the beam of the roof portion. However, if such a metal plate is fixed to the outer surface of a pillar or a beam, the high-class feeling of wood deteriorates.

Therefore, an object of the present invention is to provide a cantilever type carport made of wood, which has a sufficient strength at a connection portion between a pillar and a beam of a roof portion and which does not impair the high-class feeling of wood. To do.

[0006]

The carport of the present invention for achieving this object comprises a roof portion having a wooden beam,
A carport having an upper end connected to one end in the lengthwise direction of the beam and supporting the roof part in a cantilevered manner, wherein the beam is two wooden beam members. Is configured in accordance with the thickness direction, between the beam members, at a connection position with the column, a metal connection plate is fixedly arranged without protruding or largely protruding, and One in which (usually a plurality of) connecting bolts are passed through the upper end portion of the pillar and the connection portion between the pillar and the pillar, and the pillar and the beam are connected by using, for example, a nut. Is. The beams are arranged so as to extend in the width direction of the carport space, for example. By using a connecting plate fixed to the beam and a plurality of connecting bolts (coupling means: connecting bolts), at the connecting portion between the beam and the support, the other side of the carport space ( Sufficient detent strength can be given to the roof part that extends long on the side opposite to the pillar). Moreover, since the metal connecting plate is not exposed to the outside or hardly exposed to the outside, the carport is not deteriorated in quality. The connecting bolt penetrates the support column and the beam along the front-rear direction of the carport space, for example, and connects the support column and the beam.

The structure of the connecting portion between the beam and the column is such that the connecting plate is fixed to the beam at both ends in the length direction (both ends along the length direction of the beam), and connecting bolts (usually a plurality of bolts are used). )
However, if the upper end portion of the column and the beam are penetrated so as to penetrate the intermediate portion of the connecting plate, sufficient connection strength can be secured with a simple structure. The connecting bolt is combined with, for example, a nut to connect the beam and the column.

In order to secure a greater anti-rotation strength for the roof part, a reinforcing column having an upper end connected to one end of the beam and a lower end fixed to the lower end of the column is connected to the column. It is preferable to further provide.
