1. The vertical bearing capacity is divided into 39 levels.
2. The design horizontal force of the direction of the movable direction of the two-way movable support is not more than 5% of the vertical bearing capacity of the support.
3. The corner of the support is not less than 0.02 rad.
4. The support is divided into 5 levels according to the displacement.
5. The slope of the cast-in-place beam is adjusted by the embedded steel plate or wedge-shaped concrete block at the bottom of the beam; the slope of the precast beam can be adjusted by the pre-buried steel plate at the upper part of the support beam, or after the flat steel plate is pre-buried at the bottom of the beam. A wedge-shaped sloping plate or a wedge-shaped concrete block is added to the top surface of the support; when the slope is small, the slope can be directly adjusted on the top surface of the upper support plate.
6. The strength grade of beam concrete should not be lower than C45, and the strength grade of supporting cushion concrete should not be lower than C40.
