Abstract This wooden synthetic beam comprises an integral connection of a pair of upper and lower wooden flange members and a web member comprising a pair of wooden web plates which are provided between the flange members and inwardly curved so that central portions thereof are adhered to each other. The adhesion of the central portions of the pair of inwardly curved wooden web plates can be achieved by providing a vertical web plate lengthwise in a central portion between the curved web plates to adhere them each other through the vertical web plate or directly adhering the central portions together of the curved webs. In the case where the central portions of the curved webs are directly adhered together without provision of the central vertical web, the lengthwisely curved webs are divided in a suitable spaced relation, and a connecting bolt for reinforcement is provided on the divided portion. For the purpose of reinforcement, vertical web plates can be provided on opposite sides of the curved web plates.
A wooden synthetic beam comprising an integral connection of upper and lower wooden flange members and a web member comprising a pair of wooden web plates which are affixed, at their opposite ends, respectively, at spaced positions relative to each other, to said upper and lower wooden flange members and are accurately curved inwardly relative to each other with the central portions of said arcs of said arcuate plates adhered to each other, said pair of inwardly curved wooden plates being divided lengthwise in a suitable spaced relation, and a connecting bolt which extends through the pair of upper and lower wooden flange members being provided at said divided portion.
