摘要: A web member for a truss with high sectional strength and an assembled truss is formed by transforming ends of an M-shaped web member into two double-layer connecting plates for connection through end transformation, grooving and drilling while steel consumption is not increased; and connection joints of a conventional truss are usually controlled by bearing capacities of bolts of which the sectional strength is insufficient, the thickness of bolt connections on ends of the web member is increased by flattening, and thus, pressure bearing capacities of the bolts will be greatly improved. The truss provided by the present utility model is a fully-bolted truss, connections of two adjacent web members and chord members are connected to intersection points of center-of-gravity lines of the web members and the chord members.
