Seam is put into dedicated vulcanization adhesive tape；
Step 3：Close up two panels hot-melt plate, tighten the supporting bolt of fixture, the temperature for needing to heat well is debugged on temperature controller
Degree；
Step 4：The continuous adjustment jack in heating process, makes two pieces of die gaps just reach sealing tape thickness to be
Only, heat time 10min ± 5min, it is to be cooled to can be taken off to room temperature.
Preferably, in the step 1, vulcanization adhesive tape length is 10cm.
Preferably, in the step 2, two sealing belt ends will welding are polished 15cm respectively, the mutual lap of splice
For 10cm.
Preferably, in the step 3, temperature controller debugging temperature is set to 195 DEG C ± 10 DEG C.
The beneficial effects of the invention are as follows：The tunnel longitudinal direction longitudinally connected method of construction joint rubber fastening band is reasonable in design, with
Sulfide film welds longitudinal rubber fastening band as electric heating element, using hot-melt welding machine, waterstop hot-melt welding machine be by mould and
Control cabinet two parts form, and the electric heating element being connected with control cabinet are provided with mould, the interface shape of mould is with being heated member
Part is adapted, and the middle part of mould is provided with thermometric facility, and sulfide film is similar to the vulcanization glue material of waterstop joint, parent
Big with effect, the vulcanizing agent in sulfide film diffuses to joint interface, and reaction is crosslinked with the remaining double bond of vulcanizate, is formed
Co-vulcanization system, makes joint be connected as a single entity, and the present invention welds longitudinal direction using sulfide film as electric heating element, using hot-melt welding machine
Rubber fastening band, it is simple to operate, it can guarantee that the joint quality of rubber fastening band.
