Description

  The present invention relates to a connector used for connecting structural materials of a simple building.

  In simple buildings such as terraces and carports, frameworks are formed by connecting columns made of aluminum alloy extruded members and cross members such as beams with a connector. In a simple building, depending on the location, the column and the cross member are simply connected in an L shape, and only the cross member is connected so as to intersect the L shape, the T shape, and the cross shape in a plan view. , T-shaped, cross-shaped and connected to each other, and there is a place to connect the strut to the crossing part of the crossing, and each of these connecting points uses a dedicated connector, there are many types of connectors Therefore, the cost has increased and the assembly work has become complicated.

Patent Document 1 includes a block-shaped connecting member to which end portions of rod-shaped structural members are connected, and a block-shaped connecting member having the same size as the connecting member, as a connecting tool used when assembling a rack or the like. The thing which can comprise the joint of the various forms which connect a structural material in 2-6 directions by selectively connecting a connection member to each surface of a connection member is disclosed. In a simple building, if a heavy load is applied to the beam that supports the roof (especially when the beam is cantilevered) and the above-mentioned coupler is used, the connection member that connects the beam and the end of the column, and the connection Since the connecting member that connects the members is another member, the strength may be insufficient. Moreover, since both the connecting member and the connecting member are block-shaped, the weight of the connecting tool is increased.
JP 2000-304018 A

  The present invention has been made in view of the circumstances described above, and it is an object of the present invention to eliminate the need for a dedicated connector according to the attachment location, and in particular to make it possible to firmly connect a lateral member to which a load is applied to a column.

  In order to achieve the above object, a connector according to the first aspect of the present invention includes a connector main body and a connector, and the connector main body includes an insertion portion to a support column that protrudes downward, and a side. An insertion part to the first cross member provided so as to protrude, and a connection tool attachment part provided at least on two side surfaces perpendicular to the protruding direction of the insertion part to the first cross member and capable of attaching the connection tool. The connecting device has a connecting portion of the second cross member arranged at right angles to the first cross member and a fixing portion of the connecting device attaching portion, and attaches at least one connecting device according to the attachment location. It is attached to the part. In addition, a 1st cross member and a 2nd cross member make the cross member of a direction where load more applies among the cross members of the two directions arrange | positioned in the front-back direction and the left-right direction as a 1st cross member.

  In addition to the structure of the invention described in claim 1, the connector according to the invention described in claim 2 is substantially U-shaped having two upper and lower connecting parts and a fixing part that connects the two connecting parts. Choose between fixing the fixed part to the connector mounting part and inserting the connecting part into the second cross member, and fixing the fixed part to the side of one cross member and inserting the connecting part into the other cross member It is possible to do it.

  According to a third aspect of the present invention, there is provided a connecting tool comprising a connecting tool main body and a connecting tool, wherein the connecting tool main body is provided on a plurality of side faces and inserted into a support column protruding downward, and the connecting tool is provided. The connecting tool has a generally U-shaped connection part having two upper and lower connecting parts and a fixing part that connects the two connecting parts, and the fixing part is fixed to the connecting tool attaching part. It is possible to select one of inserting the connecting portion into the cross member and fixing the fixing portion to the side surface of one cross member and inserting the connecting portion into the other cross member. One connecting tool is attached to the connecting tool mounting portion.

  According to a first aspect of the present invention, there is provided a connector according to the first aspect of the present invention, in which the insertion portion of the connector main body is inserted into the cross member (first cross member) to which a load is more applied among the two cross members in the front and rear direction and the left and right direction. By inserting the connector, the first cross member and the support column can be firmly connected, and the connector main body has at least two side surfaces perpendicular to the protruding direction of the insertion portion to the first cross member, and the connector can be attached freely.
