[0023] (2) Installing the first roofing polymer sheet 01 and the second roofing polymer sheet 02;

[0024] The material of the roofing polymer sheet joint waterproofing device 03 is the same as that of the first roofing polymer sheet 01 and the second roofing polymer sheet 02;

[0025] The width of the roofing polymer sheet joint waterproofing device 03 is the same as the width of the first roofing polymer sheet 01 and the second roofing polymer sheet 02;
