However, the arrangement of the support is to arrange the support between the top of the ladder beam (cantilever plate) and the ladder plate. This arrangement limits the height of the support, and the vertical force of the support itself affects the power consumption of the support. It can work, and it brings great inconvenience to the construction and replacement of the support

Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] The invention proposes a replaceable stairwell structure mild steel-sliding composite damping support, thereby improving the seismic performance of the stairwell. Such as figure 1 , figure 2 As shown, the stairwell structure mild steel-sliding composite shock-absorbing bearing of the present invention includes the ladder beam cantilever plate 3 that is arranged on each layer of ladder beam 2 extending outwards and the ladder plate 6 adjacent to the top (the second The mild steel energy-dissipating support 4 between the steps where the steps are located), and the sliding support 8 arranged between the ladder beam 2 and the ladder plate 6. Utilize the cantilever at the lower part of the ladder beam 2 to increase the space height of the arrangement position of the mild steel energy-dissipating support 4, to a certain extent remove the restricti...

The invention discloses a changeable stair composite damping support and a preparation method thereof. The changeable stair composite damping support comprises a sliding support arranged between a ladder beam and a ladder plate as well as an overhanging plate arranged on the lower part of the ladder beam; a soft steel energy-consuming support is arranged on the overhanging plate; the soft steel energy-consuming support is connected with the ladder plate. Part of the ladder beam is overhung outwards, the soft steel energy-consuming support is arranged between the corresponding overhanging plateand the ladder plate, and limitation to the support height by the original support arrangement form is relieved. The end part of the ladder plate is shelved on the ladder beam, and the sliding support is arranged between the ladder plate and the ladder beam and bears a vertical force, so that the soft steel energy-consuming support only needs to exert energy-consuming effect in a horizontal and staggered way and does not bear the vertical force; through improvement on the arrangement position of the support, the properties of the soft steel energy-consuming support is significantly improved.The changeable stair composite damping support is simple in structure, convenient to design and construct, and low in production cost, and can realize safety and economy coexistence.
Description
technical field [0001] The invention belongs to building anti-seismic structures, and relates to a replaceable energy-dissipating and sliding composite shock-absorbing support for stairwells. Background technique [0002] Earthquake damage shows that frame structure stairwells are seriously damaged during earthquakes, which will cause heavy casualties and property losses. In order to reduce the seismic damage of the stair structure, when carrying out the seismic design of the stair structure, a sliding support is usually set between the stair plate and the lower end of the ladder beam, so that the stair plate can slide in the horizontal direction, and the “scissors support effect” under the earthquake is removed. ", to weaken the adverse effect of cast-in-place reinforced concrete stairs on the seismic performance of the main frame structure. Commonly used sliding bearings generally refer to the practice of the National Building Standard Design Atlas (16G101-2). The degree...
