Description
Technical field
The present invention relates to the stair of building, be specifically related to a kind of spacing bearing of concrete staircase damping and work progress.
Background technology
Traditional construction design method does not accounts for the impact on integrality performance of the structure of the stair stress, does not the most consider stair
Earthquake load effects.Wenchuan earthquake earthquake shows, under big shake effect, the staircase of building destroys serious, including waist slab, ladder
Beam and the heavy damage of cleat stanchion.
The 6.1.15 article regulation of " seismic design provision in building code " GB50011-2010: " for frame structure, staircase component with
Agent structure is whole when watering, and should count staircase component to geological process and the impact of effect thereof, should carry out staircase component antidetonation carrying
Power checks ".And after staircase component participates in structure overall calculation, staircase component size and the area of reinforcement add senior general and cause staircase
Local stiffness amplifies again, and the shearing that geological process is distributed between going downstairs increases again.In order to weaken stair with integrally-built
Connecting, " the board-like stair of cast-in-place concrete " (11G101-2) proposes the way of slip stair, is connected with low side ladder beam in bench
Place's design sliding support.And the stair that slide design sliding support in bench and low side ladder beam junction, whole bench then becomes outstanding
Arm member, under geological process, bench low side just produces violent jump phenomena of encorbelmenting, and easily makes bench with high-end ladder beam even
Meet place by drawing crack.Notification number is that CN 203569719 U Chinese patent has been invented energy-dissipating and shock-absorbing on the basis of slip stair and propped up
Seat, designs energy-dissipating and shock-absorbing bearing in bench with low side ladder beam junction.But energy-dissipating and shock-absorbing bearing is placed in structure, becomes structure
A part, causes the energy-dissipating and shock-absorbing bearing later stage cannot to be overhauled and change, and energy-dissipating and shock-absorbing pedestal configurations is complicated, difficulty of construction
Greatly." national building standard design atlas " (G310-1～2) give also precast concrete stair according to stair connecting structure
Be slidably connected structure way.But the structure way interior joint that is slidably connected of precast concrete stair connects complexity, difficulty of construction
Greatly.
