    摘要： An elongated structural member, which is suitable for use as a joist, beam, girder or the like, comprises first and second webs, each having a generally arcuate cross-sectional shape and, thus, one convex surface and an opposing concave surface. The webs are disposed in generally mutually parallel relation with their respective convex surfaces in confronting relation, one diverging from the other in both an upper region and a lower region. A wedge is interposed between, conforms to, and is intimately joined to the confronting convex surfaces of the webs in at least a portion of each of the upper and the lower regions. The webs are made of plywood and the wedges are made of solid wood. The wedges are capable of bearing substantial compression and tension loads so that together with the portions of the webs to which they are intimately joined, they can accept and support great loads on the member when mounted in span. More particularly, each wedge has a tension or tensile strength on the order of at least 950 pounds per square inch and a compressive strength on the order of at least 950 pounds per square inch.

    摘要翻译： 适合用作托梁，梁，梁等的细长结构构件包括第一和第二腹板，每个腹板具有大体上弓形的横截面形状，因此具有一个凸面和相对的凹面。 腹板以相对的相对平面的关系布置成相互平行的关系，一个在上部区域和下部区域中彼此分开。 在上部和下部区域中的每一个的至少一部分中间插入有楔子，并且紧密地连接到腹板的相对的凸形表面。 纤维网由胶合板制成，楔形物由实木制成。 楔形件能够承受相当大的压缩和拉伸载荷，使得与其紧密接合的腹板的部分一起，当安装在跨度中时，它们可以接受和支撑构件上的大负载。 更具体地说，每个楔具有约至少950磅/平方英寸的抗拉强度和至少950磅/平方英寸的抗压强度。
