[0002]
[Prior art]
This type of horizontal beam is generally connected to a hollow side beam made of aluminum extruded material using a synthetic resin-integrated joint member with protruding side beam fitting parts that fit into the horizontal beam hollow part on both sides of the board. , Each side beam fitting part is fitted and disposed in the hollow part of the horizontal beam so that the end surfaces of each side of the joint member are butt-matched, and screwed into the horizontal beam fitting part of the joint member from one side of the horizontal beam This is done by fixing with screws.
[0003]
[Problems to be solved by the invention]
In this case, since the joint member is premised on a horizontal beam having a hollow portion made of an aluminum extruded material, for example, the aluminum extruded material is made as thin as possible and a synthetic resin, for example, a foamed resin, is used for reinforcement. Or a solid crosspiece that is also filled with foamed resin for reinforcement in the molded outer shell formed by roll forming of a thin metal plate. In addition to the complicated work of removing the foamed resin filled at the expense of reinforcement, the screws fix the crosspiece fitting part in close contact with the outer side of the thin crosspiece. Therefore, depending on the state of the horizontal beam or the horizontal beam fitting portion, the portion may be broken or uneven.
[0004]
The present invention has been made in view of such circumstances, and a solution to that problem is that it can be suitably used for a thin-walled solid horizontal beam using the above-mentioned foamed resin as a reinforcing means.
