Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described in detail:
A kind of staircase structure slip energy dissipating support, as shown in Figure 1, every layer of stair stringer 1 with above adjacent gangboard 2 lower end between be provided with one group of support body, this support body includes cushioning members, cushioning members upper, lower surface is connected to upper junction plate 7 and lower connecting plate 7 ', two widthwise edges at upper junction plate 7 are vertically arranged with multiple upper anchorage bolt 8, two widthwise edges at lower connecting plate 7 ' are vertically arranged with multiple lower anchor bolt 8 ', upper junction plate 7 is by upper anchorage bolt 8 and gangboard 2 anchor connection, lower connecting plate 7 ' is by lower anchor bolt 8 ' and stair stringer 1 anchor connection, it is provided with prearrangement of deformation amount district 9 in the both sides of cushioning members. being provided with implant in prearrangement of deformation amount district 9, implant is the one in hollow thin type steel plate or hollow plastic flitch or foam or rock-wool heat insulation plate or polypropylene extruded sheet. when implant is hollow thin type steel plate or hollow plastic flitch, by folding for plate make one hollow box-like, be then attached to the inwall place in prearrangement of deformation amount district 9, it is prevented that concrete falls into wherein.
The embodiment 1 of cushioning members is rubber blanket (not shown). Rubber blanket is connected with the cantilevered plate 4 of stair stringer 1 by lower connecting plate 7 ' and lower anchor bolt 8 '.This rubber blanket should meet the engineering objectives such as durability, intensity, rigidity, deformation.
The embodiment 2 of cushioning members as shown in Figure 2 and Figure 3, including power consumption central layer, has several power consumption central layer holes 5 on power consumption central layer, forms power consumption stem stem 6 between the power consumption central layer hole 5 that each two is adjacent. According to practical situation, power consumption central layer hole 5 may be designed as rectangle, hexagon or cydariform (namely upper and lower two bases are straight line, and limit, the left and right sides is cambered outwards camber line) or other can make stem stem fully surrender the shape of power consumption. Power consumption central layer is made up of any one in the mild steel such as Low Yield Point Steel LY100, Low Yield Point Steel LY160, Low Yield Point Steel LY225 or mild steel Q235. Power consumption stem stem 6 is connected with the cantilevered plate 4 of stair stringer 1 by lower connecting plate 7 ' and lower anchor bolt 8 '.
The quantity of upper anchorage bolt 8 and lower anchor bolt 8 ' is determined according to calculating.
For precast stair, it is reserved with prefabricated gangboard hole to be provided 3 in the bottom of gangboard 2, during installation, upper anchorage bolt 8 is inserted in prefabricated gangboard hole to be provided 3, then block again through grouting, accomplish that prefabricated gangboard is connected with bearing.
During for guaranteeing earthquake, gangboard 2 can level slide, and arranges prearrangement of deformation amount district 9 in bearing both sides, and implant is the one in steel plate or plastic plate or foam or rock-wool heat insulation plate, in order to avoid the concrete built or building coats can stop.
This utility model, by arranging based on the cushioning members of rubber blanket or power consumption central layer, while gangboard " bridging effect ", can provide redundant constaint for staircase structure when earthquake laying down staircase structure, it is ensured that the big shake safety of staircase.
