The invention provides a construction method of an anchor ear gusset plate and the ceiling joist. The main body of the upper half anchor ear plate is an inverted sulciform flat steel plate; the two lateral surfaces of the sulciform flat steel plate are symmetrically welded with two angular steel plates, which function as bolt connecting plates, wherein the bottoms of the angular steel plates are provided with bolt holes. The structure of the lower half anchor ear plate is symmetrical with the structure of the upper half anchor ear plate, wherein the bottom surface of the lower half anchor ear plate is connected with the gusset plate; the bottom surface of the gusset plate is connected with the horizontal gusset plate and the vertical gusset plate which intercross vertically; the horizontal gusset plate and the vertical gusset plate are respectively provided with a main keel connecting hole and a secondary keel connecting hole. The upper half anchor ear plate and the lower half anchor ear plate environ the steel truss steel truss; the upper half anchor ear plate, the lower half anchor ear plate and the steel truss are connected with each other fixedly via bolts, the main connecting hole is connected with the main keel via bolts and the secondary keel is connected with the secondary keel via bolts. The fabricated construction product and the construction method are capable of avoiding redundant welding modes, reducing the building energy consumption, speeding up the construction speed, and are widely applicable in the ceiling suspending work of buildings of various steel structures.
Description
(1) Technical field [0001] The invention relates to a building suspended ceiling connecting piece, in particular to a connecting piece between a suspended ceiling keel and a steel truss. (2) Background technology [0002] Terminal 3 of the Capital International Airport is one of the important projects of the 2008 Beijing Olympic capital construction project, and it is the first international hub airport terminal in China. The roof truss of the building is a super-large two-way curved steel grid structure. In the ceiling decoration project of the terminal building, the difficulty is that welding is not required for each joint, and each joint is adjustable, detachable, and easy to replace. In the construction of the suspended ceiling, how to make the connection between the ceiling keel and the steel truss firm, avoid welding and adjust the keel is a technical problem in the construction, and the traditional hugging The hoop cannot achieve the adjustment function. (3) Conten...
