The invention discloses a connecting joint between a hollow steel tube concrete column and a steel girder and a construction method thereof. The joint comprises a hollow steel tube concrete column, a steel girder, an end plate and a high-strength bolt, wherein the end plate is welded at the steel girder end; the steel girder end at the joint is connected with the hollow steel tube concrete column through the end plate and a bolt and is connected with a column through the prestressed high-strength bolt. In the construction method, the concrete in the steel tube can be prefabricated or cast in situ; the end plate can be welded in a factory; bolt holes on the end plate and the steel tube are preformed in the factory; and only bolt connection needs on-site construction. The joint structure has the advantages of economy, practicality, definite force transmission, simple manufacture, high prefabrication degree, convenient construction, and capacities of avoiding on-site welding and improving joint shock resistance and construction benefit.
