In the aspect of arrangement of the steel plates, the steel plates are pressed one by one from the starting point and extend backwards, 1cm of dense splicing is lapped at the joint, and the steel plates are fixedly connected through a rivet with the distance of 50 cm. The points of the vibration isolation blocks need to be checked one by one before being laid, steel plates are placed on the vibration isolation blocks after the detection is qualified, and the steel plates are placed in a horizontal and light manner to prevent collision. When the vibration isolation block is placed, any sundries are strictly checked along with the cleaning and strict inspection of the steel plate, and the vibration isolation block which is fixed according to a positioning diagram is strictly prohibited to move. The steel plate surface needs to be smooth, the edge is neat, and the steel plate surface needs to be paved in a staggered mode.
In the aspect of the waterproof coiled material, the waterproof coiled material needs to be laid and pasted flatly without warping, the joint is tight, the adjacent positions are overlapped for 5 centimeters, the joint is tightly bonded, and no gap is left. And the waterproof layer 5 is rolled to the upper opening of the peripheral isolation plate as necessary and turned up by 15cm to prevent mortar from flowing into the lower layer to form an acoustic bridge. The upturning waterproof coiled material on the periphery needs to be pasted with the template structure column to be smooth and firm, and a cavity is avoided when concrete is poured.
In the aspect of the edge sealing vibration isolator, the edge sealing vibration isolator extends into the floating ground, is flush with the bottom surfaces of the vibration isolators 3 and the rock wool, is adhered to the template and the structural column smoothly and firmly, needs to be cut in advance, and leaves a gluing depth below the concrete surface with the height of 100.
