Description

  The present invention relates to a connecting member for connecting a girder member arranged vertically and horizontally, which is a framework of a building, and a column member arranged vertically, and more specifically, used in an event where a large load is applied. The present invention relates to a connecting member that can also be used for a stage used as a storage shelf for goods in a stage or a warehouse.

  Conventionally, a stage used in an event, etc., or a stage used as an article storage shelf in a warehouse, is placed on a girder member of a support base composed of girder members arranged vertically and horizontally and strut members arranged vertically. Appropriate floor panels are installed, and a large number of the same support bases are used.

  In addition, since the support base must safely support the stage against vibrations caused by loads and vibrations on the stage, when the support base is manufactured at the factory, the girders arranged in the vertical and horizontal directions of the support base Since the members and the column members arranged in the vertical direction are connected by welding, the girder member and the column members are firmly fixed without looseness, and people and articles on the floor panel of the stage It can be safely supported.

  However, when transporting or storing the support table, the beam members arranged in the vertical and horizontal directions of the support table and the column members arranged in the vertical direction are connected by welding, so that the beam members and the column members are separated. Therefore, when transporting, the quantity that can be transported at one time is limited, and when storing, a large space is required, and further, the length of the column member is appropriately selected according to the desired height. There was no degree of freedom.

  From this, for example, as described in Patent Document 1, two strut members of the four strut members are integrated with the truss structure to give strength, and the girder member and the strut member Although the stage can be separated, the stage should allow the transporter to pass at least in the front-rear or left-right direction of the stage when putting in and out the article placed on the stage installation floor below the floor panel in the stage. As a result, there is a risk of rattling in a direction perpendicular to the passing direction of the transporter.

Since the end of the column member to be connected next to the connecting body integrated with the connecting body can be inserted into the gap, and the side walls of the column member are tightened by the both side walls of the connecting body narrowed by the tightening means, so at least the connection The side wall corner on the side wall upper end portion side of the connecting body of the support member is firmly held by the both side wall surfaces of the main body, and the support member is pressed against the bottom of the groove of the connecting body. It can be supported in the entire area of the bottom of the groove in the connection main body serving as a support site, and therefore the column member can be equally supported without backlash.

  In addition, since the connection main body and the column member are connected and fixed, the both side wall surfaces of the connection main body press and fix the side wall corner on the side wall upper end of the connection main body of the column member. The width between both side walls of the connection body can be made wider than the width of the support member inserted into the connection body. Therefore, the support member can be smoothly inserted into the groove of the connection body during assembly.

  Furthermore, since the support of the beam member by the column member is supported by the block body fixed to the column member, as compared with the conventional example in which the beam member is supported by the bolt connecting the column member and the beam member, It is possible to stably and firmly support a girder member to which a large load is applied.

  And, since the girder member and the support member can be separated and the support members are provided one by one, when transporting the support base, the quantity that can be transported at a time can be increased, and the space required for storage is sufficient. Can be stored.

  From these, it can be applied not only to the stage used in an event where a large load is applied and the stage used as a storage shelf for goods in a warehouse, but also as a connecting member when connecting a framework in a building such as a prefab house. .
