Drain bar is facilitated to install.
Further, the connection trench bottom offers guiding gutter, and the water guide trench bottom offers the connection draining
The leakage hole in channel.
By using above-mentioned technical proposal, when adjacent drainage channel plate stitching portion has water along the junction of link block and link slot
When leaking down, the water to leak down can focus on guiding gutter, then be guided to water in drainage channel by the leakage hole of water guide trench bottom, keep away
Exempt from water and drains to insulating layer, and then broken ring insulating layer from stitching portion.
Further, the adjacent drain bar junction is coated with marine glue.
By using above-mentioned technical proposal, drain bar joining place can be further sealed, the leakage of water is avoided, protect lower section
Thermal insulation board.
Further, the drain bar is both provided with waterproof layer and/or insulating layer junction for improving bonding strength
Rough surface.
By using above-mentioned technical proposal, the setting of rough surface can be improved between connecting plate and waterproof layer and/or insulating layer
Contact area, to improve the bonding strength of junction.
Further, the rough surface includes dot bulge or wavy bulge.
By using above-mentioned technical proposal, the contact area between connecting plate and waterproof layer and/or insulating layer is improved, from
And improve the bonding strength of junction.
Compared with prior art, the utility model has the advantages that：
1, by the setting of drainage blanket, it can stop that water enters insulating layer and with lower structure after waterproof layer is destroyed；Work as row
After water layer is locally destroyed, by the setting of drainage channel, ponding and leak is discharged from drainage channel, avoid seeping phenomenon,
Protect insulating layer and with lower structure；
2. after waterproof layer is destroyed, the marine glue for bonding adjacent drain bar exposes in air, and meeting aging for a long time is led to
The setting of guiding gutter and leakage hole is crossed, the water for draining to adjacent drainage channel plate intersection can be introduced into drainage channel, water is discharged.
