Embodiment Construction
[0037] The invention provides a composite frame and a connecting piece in which the grid frame and the truss are on the same plane, which can realize the connection of the grid frame and the truss formed by the connection of new hub nodes, so as to meet the use requirements of long-span components.
[0038] The present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can accurately understand the technical solution of the present invention.
[0039] Words such as first and second described herein are only used to distinguish different components with the same or similar structure, or different structures with the same or similar structure, and do not represent a special limitation on the sequence.
[0040] Such as figure 1 As shown, the present invention provides a composite frame in which the network frame and the truss are on the same plane, wherein the network frame 7 includes hub nodes 4 and several...

The invention provides a combined framework with a grid frame and a truss being located on the same plane and a connecting piece. The novel grid frame and the truss can be connected so that the use requirement of a large-span member can be met, wherein the grid frame is formed by connecting hub joints. The connecting piece comprises an auxiliary plate, a first inserting-connecting part and a second inserting-connecting part, wherein the auxiliary plate is fixedly connected with the truss; the first inserting-connecting part is provided with a first inserting-connecting end and a first connecting portion detachably connected with the auxiliary plate; and the second inserting-connecting part is provided with a second inserting-connecting end and a second connecting portion matched with the corresponding hub joint of the grid frame in a mortise and tenon joint mode, and the first inserting-connecting is matched with the second inserting-connecting in an inserting-connecting mode. The auxiliary plate, the first inserting-connecting and the second inserting-connecting are all detachably connected, so that the relative positions of the grid frame and the truss are convenient to adjust, and accurate installation is further achieved. Due to the arrangement of the second inserting-connecting part, mortise and tenon joint fit between the second inserting-connecting part and the corresponding hub joint can be achieved, and therefore connection reliability is high, dismounting and mounting convenience is improved, stress is optimized, the carrying capacity and safety are improved, and the large-span requirement is better met.
Description
technical field [0001] The invention relates to the technical field of long-span steel structures, in particular to a composite frame and a connecting piece in which a net frame and a truss are on the same plane. Background technique [0002] In the field of steel structure technology, such as the closed design of coal yards, due to the large span of some projects, grid frames cannot be used alone. At this time, it is necessary to use grid frames and trusses to form the entire structure. [0003] At present, the network frame in the prior art is connected by bolted ball joints, but the bolted ball joints can only bear tension and pressure, and the rods cannot bear lateral loads and bending moments; moreover, the length of high-strength bolts screwed into the bolted ball joints It is difficult to judge with the naked eye, and the quality problem of "false tightening" is very easy to appear, and the safety is poor; since the net frame is usually at a high altitude, purlins are...
