Description

Technical Field

[0001] The present invention relates to the technical field of assembled building structures, and in particular to an assembled composite frame, which can conveniently replace components and is of great significance for saving the cost required for reconstruction. Background Art

[0002] The assembled RCS beam-column composite frame is generally composed of prefabricated reinforced concrete columns and prefabricated steel beams. In order to ensure the stability of the connection between the prefabricated reinforced concrete columns and the prefabricated steel beams, it is necessary to use corresponding connection mechanisms to fix the prefabricated steel beams to the outer steel plates of the prefabricated reinforced concrete columns.

[0003] Research shows that the assembled RCS beam-column composite frame with strong columns and weak beams has good seismic performance. For assembled RCS composite frames, they are often made into "strong columns and weak beams" structures, so when encountering earthquakes, it is often the steel beams that are damaged, while the concrete columns are not damaged. Since there are not many obstacles during the initial installation of steel beams, the installation is relatively convenient. However, when they are replaced later, due to the obstacles of many buildings, such as the floor slabs set on the upper part of the prefabricated steel beams, the difficulty of replacement is actually quite large. In many cases, it is not feasible to operate at all.

[0004] Therefore, the research purpose of the present invention is to design an assembled composite frame that can quickly replace prefabricated steel beams when they are damaged, so as to conveniently replace the damaged prefabricated steel beams and significantly reduce the cost of reconstruction.

[0024] During the installation of the prefabricated steel beam, the corresponding rotary cylinder can be driven to lift the prefabricated steel beam upward until the web of the prefabricated steel beam is inserted into a group of clamping steel plates through the plug-in groove, and then the web of the prefabricated steel beam is fixedly installed between a group of clamping steel plates through the corresponding high-strength locking bolts; during the disassembly of the prefabricated steel beam, it is only necessary to remove all the high-strength locking bolts, and then start the reverse rotation of the rotary cylinder to directly lower and recover the prefabricated steel beam, so that the prefabricated steel beam can be quickly replaced when it is damaged, so that the damaged prefabricated steel beam can be replaced conveniently, thereby significantly reducing the cost required for reconstruction.

[0025] 2) Based on the fixed combination of the web of the prefabricated steel beam and a group of clamping steel plates, the present invention further intervenes with an upper fixing plate and a lower fixing plate to significantly improve the overall connection stability between the prefabricated steel beam and the connecting mechanism, thereby effectively ensuring the practical effect of the present invention.

[0026] 3) The drive shaft of the present invention is mainly fixed by a mounting box fixed to the outer steel plate. Therefore, except for the force applied during the lifting process, the drive shaft will not be subjected to external force at other times. Even when an earthquake occurs, it is not easy to be damaged as a single component. Therefore, the service life of the drive mechanism components of the present invention can be ensured, thereby further effectively ensuring the practical effect of the present invention.

[0027] 4) A rotating cylinder mounting plate is fixedly connected to one side of the mounting box of the present invention, and the rotating cylinder is detachably fixedly mounted on the rotating cylinder mounting plate, and the driving shaft is detachably connected to the output shaft end of the rotating cylinder by flange docking; in this way, after completing the lifting and locking operations of the prefabricated steel beam, the rotating cylinder can be disassembled in time, thereby improving the utilization turnover rate of the rotating cylinder, so as to further effectively ensure the practical effect of the present invention.

[0028] 5) The installation box of the present invention is fixedly connected with a fixing sleeve sleeved on the driving shaft, and a tightening bolt is installed on the fixing sleeve by a threaded connection. After the driving shaft winds the lifting wire rope into place, that is, after the prefabricated steel beam is hoisted into place, the tightening bolt is rotated inward to tighten and fix the driving shaft, thereby ensuring the stability of the lifting wire rope and the driving shaft under normal conditions, so as to ensure that when the prefabricated steel beam needs to be replaced later, the lifting wire rope and the driving shaft can be directly put into use.

[0029] 6) The top of the outer end of the web of the prefabricated steel beam of the present invention is arranged in a slanted groove shape to facilitate the installation of the wire rope fixing hook. The bottom of the wire rope fixing hook is fixed to the top of the outer end of the web of the prefabricated steel beam by a threaded connection, and the connection between the wire rope fixing hook and the web of the prefabricated steel beam is also fixed by a corresponding weld. The intervention of two fixings ensures the installation stability of the wire rope fixing hook. BRIEF DESCRIPTION OF THE DRAWINGS
