Both ends of the roof beam 11 are detachably connected to an anti-seismic component 3, and the roof frame 1 transmits load and stress downward through the anti-seismic component 3. In this embodiment, the detachable connection method adopts bolt connection.

The support frame 2 includes a side column 21, a connecting beam 22 connecting the upper parts of the two side columns 21, and a middle column 23 supporting the connecting beam 22 between the two side columns 21. The side column 21 is the main support of the steel structure workshop, and is resistant to bending. Shear design strength is greater than other steel members. The purpose of connecting the connecting beams 22 between the side columns 21 is mainly to share the stress between the side columns 21 during an earthquake. When the stress is too large, the plastic deformation of the connecting beams 22 can absorb a part of the seismic energy and reduce the risk of overall collapse. Because the span of the connecting beam 22 under the roof beam 11 is relatively large, the central column 23 is mainly used to share the load and enhance the deformation resistance of the connecting beam 22 . The anti-seismic assembly 3 includes a connecting sleeve 31 and a connecting column 34 passing through the connecting sleeve 31 , and the connecting sleeve 31 is connected with the roof beam 11 by bolts.

Materials with different elastic moduli are selected for the shock-absorbing member 32 and the buffer member 35, so that the shock-absorbing component 3 has better buffering and shock-absorbing performance.
