Abstract
A compound truss comprises a hollow pipe type column and a plate type engaging element. The pipe type column at least comprises two supporting pipes. A horizontal connecting element is arranged between the adjacent two supporting pipes. In a radial section of the supporting pipe, a connection between the horizontal connecting element and supporting pipe is arranged at an inner side of the largest polygon formed by the supporting pipes. The plate type engaging elements are fastened in the supporting pipes and at an outer wall of an end close to the any end of the supporting pipe. The plate type engaging element is provided with at least one round hole and one bolt point. The trusses are fastened by fastening elements at the plate type connecting elements, which can finish an engagement of the trusses. The supporting pipe can adopt arc pipe fittings and truss combinations can realize an arc formation, improve application flexibility of the truss and reduce costs.
Description
Technical field:
The utility model relates to a kind of structure of building, particularly a kind of three-dimensional frame structure, especially a kind of composite roof truss.
Background technology:
The scape support of making that is used for stage, exhibition, meeting-place layout in the prior art generally is made up of hardware, the straight ellbeam that described hardware normally is made of metal framework, and described straight ellbeam is inter-connected via a bolt joint the formation support.
Summary of the invention:
Technical problem to be solved in the utility model is: because in the prior art, the scape support of making that is used for stage, exhibition, meeting-place layout generally is made up of hardware, the straight ellbeam that described hardware normally is made of metal framework, described straight ellbeam is inter-connected via a bolt joint the formation support, so it is restricted on the mode of combination, use inconvenience, manufacturing cost is also higher.The utility model is to solve the problems of the technologies described above the solution that is adopted to provide a kind of composite roof truss, described this composite roof truss comprises hollow tubular leg and tabular joint element, wherein, described hollow tubular leg comprises two stay pipes at least, in common application of the present utility model, described hollow tubular leg comprises four stay pipes, be provided with horizontal connecting elements between any adjacent two stay pipes in described stay pipe, fixedly connected with the stay pipe at two ends respectively in the two ends of described horizontal connecting elements, in the radial section of described stay pipe, the junction of described horizontal connecting elements and stay pipe is arranged on the maximum polygonal inboard of described stay pipe and stay pipe formation, between described stay pipe and stay pipe, the stay pipe outer wall place of any end proximal end face of stay pipe, be fixedly connected with described tabular joint element, described tabular joint element is provided with at least one circular hole and at least one bolt hole, edge at described tabular joint element, can also be provided with stiffener, the outer wall of described stiffener and stay pipe is fixed, in any end of any one stay pipe, an inner sleeve can also be set, when truss engages with truss, inner sleeve can extend in the stay pipe in another truss, and fix with tightening member by the screw that is arranged on inner sleeve and the stay pipe, to strengthen the intensity of truss and truss joint, hollow tubular leg in a kind of composite roof truss of the utility model can adopt columniform stay pipe, also can adopt axially curved stay pipe, when adopting columniform stay pipe, described stay pipe is parallel to each other, when adopting axially curved stay pipe, the radian of all stay pipes is identical.The course of work of the present utility model is: truss of the present utility model and truss are connected and fixed with tightening member at its tabular joint element place, can finish engaging of truss and truss, use the truss of straight shape stay pipe to pass through combination, can make truss and truss finish arc structure with the truss that uses the arc stay pipe.The utility model and prior art contrast, because the proximal end face place at stay pipe is provided with tabular joint element, so can realize engaging of truss and truss by tabular joint element, simultaneously, also can realize the connection of the truss that the stay pipe by different numbers constitutes by tabular binding member, easy to use, simultaneously, stay pipe can adopt straight shape and arc, so can realize arc structure after the truss combination, improve the application flexibility of truss, and lowered cost.
