Assembly method for low-layer frame structure system

Abstract

The invention relates to an assembly method for a low-layer frame structure system. The method includes the following steps that 1, a foundation is arranged, and frame pillars are installed; 2, a second-layer beam is assembled, wherein prefabricated beams are lifted, side pillars and middle pillars are fixedly connected with two or more oppositely-arranged prefabricated beams, connecting parts arearranged on the upper portions and the lower portions of the prefabricated beams, the connecting parts at least comprise first connecting plates and second connecting plates, the first connecting plates and the second connecting plates are perpendicular to each other and abut against the frame pillars and the prefabricated beams respectively, horizontally-arranged split bolts penetrate through the frame pillars and then are fixedly connected with the first connecting plates on the two sides of the frame pillars, and vertically-arranged split bolts penetrate through the prefabricated beams andthen are fixedly connected with the second connecting plates on the two sides of the prefabricated beams; 3, a second-layer floor slab is assembled; 4, a roof beam is assembled, and the assembling process is identical with that in the second step; 5, a roof panel is assembled. All the components in the method are connected through a dry method, connecting joints of all the components form dry type connection and form an integral, processes are reduced, construction speed is high, and construction is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an assembly method of a low-rise frame structure system. Background technique [0002] The prefabricated frame structure can greatly improve the construction capacity and construction speed, save a lot of labor and ensure the construction quality. The connection mode in the prefabricated frame structure system is the core issue of the structure, and it is also the weak link of the structure. As long as the joint parts of the prefabricated components are reliably connected, the safety and reliability of the structure can be guaranteed. At present, the conventional beam-to-column connection mainly adopts the method of laminated beams. Although this method can ensure the integrity of the joints and the reliability of the connection, there is a lot of cast-in-place work, and most of the joints are wet operations on site. Complex, difficult to operate, slow ...
