Problems solved by technology

Another study proposed that in order to further reduce the impact of the stairwell structure on the seismic performance of the main structure, measures to separate the intermediate rest platform from the main structure can be taken, such as the four-pillar support scheme, which can effectively reduce the vibration coupling between the stairwell structure and the main structure However, under rare earthquakes, the structure of the stairwell will have a large horizontal displacement. When the prefabricated stair slab is supported, there will be problems such as free displacement constraints, plastic deformation concentration, and node connection failure.

Embodiment Construction

[0019] refer to Figure 1-Figure 4 , the present invention proposes a prefabricated staircase of grinding, sliding and shock-absorbing type, which includes a prefabricated stair 1, a fixed platform 2 and a sliding platform 3, one end of the prefabricated stair 1 is connected to the fixed platform 2 through a fixed hinge mechanism and the other end is passed through The milling sliding guide reset mechanism is connected with the sliding platform 3 .

[0020] In the present invention, the prefabricated ladder board is connected with the sliding platform through the milling sliding guide reset mechanism, and the connection structure is realized. During the elastic deformation of the structure under frequent earthquakes, the prefabricated ladder board 1 and the sliding platform 3 do not produce relative displacement, and the connection structure is realized. During the elastic-plastic deformation of the structure under fortification intensity earthquakes and rare earthquakes, the ...

Abstract

The invention provides a grinding sliding damping type prefabricated staircase. The grinding sliding damping type prefabricated staircase comprises a prefabricated staircase plate, a fixed platform and a sliding platform, wherein one end of the prefabricated staircase plate is connected with the fixed platform through a fixed hinge mechanism, and the other end of the prefabricated staircase plateis connected with the sliding platform through a grinding sliding guide reset mechanism. The grinding sliding damping type prefabricated staircase has the advantages of being simple in structure, clear in mechanism, easy and convenient to construct and the like, is suitable for staircase units of frame parts in frame structures and frame-shear structures, and is particularly suitable for staircaseunits with middle rest platforms and main body frames connected in a separated mode, and the supporting mode of a movable hinge support of the prefabricated staircase plate is changed into the supporting mode of a sliding damping support, so that the problems that when an existing separated connection technology is applied to an assembly type building, the staircase plate has vibration jumping and overlarge horizontal displacement are effectively solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a grinding slip shock-absorbing prefabricated staircase. Background technique [0002] Stairs have the functions of vertical traffic passages and escape routes during earthquakes in multi-storey and high-rise buildings. In the connection mode of integral pouring, the ladder slabs form a diagonal brace effect and participate in the structure's lateral force resistance, resulting in complex stress on the stairwell. During an earthquake, the stairwell is often destroyed first because it absorbs more energy, forming the first earthquake-resistant structure. The line of defense did not realize the aforementioned anti-earthquake and disaster relief functions as expected. [0003] In order to solve the seismic problem of stairwells in frame structures, the current seismic design codes and related atlases propose a separate connection technology for stair slabs, that is...
