Abstract

The invention relates to the field of fabricated prefabricated stair construction, and particularly discloses an energy dissipation rotating type connecting method for stair joint connection. The method comprises the following steps of 1 prefabricating parts, 2 laying a horizontal damping seismic isolation layer, 3 placing prefabricated stair ends, 4 connecting a bottom rotating steel plate, 5 filling in gaps and 6 connecting a top rotating steel plate. According to the connecting method, the connected rotating steel plate can supply certain rotation and can also supply vertical restraint andhorizontal restraint, when stairs are vibrated, the damping seismic isolation layer supplies certain deformation, the rotating steel plate can supply a certain rotating amount, the damping seismic isolation layer is matched with the rotating steel plate, and the anti-seismic performance of stairs is effectively improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated staircase construction, in particular to an energy-consuming rotary connection method for stair node connection. Background technique [0002] With the development of society, prefabricated concrete structures are widely used at home and abroad because of their advantages of convenient construction, short construction period and less environmental pollution. In prefabricated housing construction, stairs are used as vertical transportation channels, and the safety and usability of their node connections are particularly important. At present, in residential buildings, industrial buildings, and public buildings, most of the node connections of stairs use cast-in-place connections. The construction process is to set up the formwork at the construction site, bind the steel bars, and pour the concrete. There are a large number of steel bar binding and pouring operations in the cast-in-place con...
