Description
Technical field
The present invention relates to the stair of building, and in particular to a kind of spacing bearing of concrete staircase damping and work progress.
Background technology
Traditional construction design method does not account for influence of the stair stress to integrality performance of the structure, without considering stair yet
Earthquake load effects.Wenchuan earthquake earthquake shows that the staircase of the big lower building of shake effect destroys seriously, including waist slab, ladder
The heavy damage of beam and cleat stanchion.
《Seismic design provision in building code》The 6.1.15 articles regulation of GB50011-2010：" for frame structure, staircase component with
Agent structure is whole when pouring, and should be included in influence of the staircase component to geological process and its effect, should carry out staircase component antidetonation carrying
Power checks ".And after staircase component participates in structure overall calculation, staircase component size and area of reinforcement increasing will cause staircase
Local stiffness amplify again, the shearing that geological process is distributed between going downstairs increases again.In order to weaken stair and overall structure
Connection,《The board-like stair of cast-in-place concrete》(11G101-2) proposes the way for sliding stair, connects in bench and low side ladder beam
Connect place's design sliding support.And slide stair then becomes in bench and low side ladder beam junction design sliding support, whole bench
Cantilever member, bench low side just produces violent overhanging chattering under geological process, easily make bench with high-end terraced beam
Junction is by drawing crack.Notification number has invented energy-dissipating and shock-absorbing for 203569719 U Chinese patents of CN on the basis of stair are slided
Bearing, in bench and low side ladder beam junction design energy-dissipating and shock-absorbing bearing.But energy-dissipating and shock-absorbing bearing is placed in structure, is become
A structure part, causes the energy-dissipating and shock-absorbing bearing later stage can not overhaul and replace, and energy-dissipating and shock-absorbing pedestal configurations are complicated, construction
Difficulty is big.《National building standard designs atlas》(G310-1~2) also give concrete Tulou according to stair connecting structure
The construction way that is slidably connected of ladder.But the construction way interior joint connection that is slidably connected of precast concrete stair is complicated, construction
Difficulty is big.
