A kind of Side fascia waterproofing node
Technical field
This utility model belongs to building structure field, is specifically related to a kind of Side fascia waterproofing node.
Background technology
In assembled architecture industry, Side fascia uses prefabricated mode to carry out factorial praluction, then Assembling, thus
Standardization can be realized, and quality controllable, efficient quick.But, during the assembled in situ of precast wall panel, be to its stitching portion
Carry out water-proofing treatment, it is to avoid rainwater penetrates into indoor along the splicing seams of Side fascia, if infiltration phenomenon is serious simultaneously, connection will be caused
Loosening in position, life-time service causes effective bearing load ability of precast facade to decline, and brings great hidden dangers in project.Tradition
Waterproof being typically of out-hung panel break marine glue at seam crossing, the workload not only constructed is big, and marine glue is over time
There will be aging for a long time, finally result in the generation of drainage, affect water resistance and the construction quality of assembled architecture.
At present, Side fascia waterproof type generally uses tongue and groove waterproof, i.e. the junction moulding at wallboard has inner side height, outside
The waterproof tongue and groove of the low discrepancy in elevation, stops outdoor rain to leak out to indoor, i.e. use this side in existing Side fascia application technology code
Formula carries out waterproof;In prior art, patent 205116466U discloses the waterproof knot of the cladding node of a kind of assembled architecture outer wall
Structure, this waterproof construction is also mainly under prefabricated cladding Side fascia upper end and on the junction of prefabricated cladding Side fascia lower end make
Type has the waterproof tongue and groove of the discrepancy in elevation that inner side is high, outside is low to carry out water-proofing treatment.But, after Side fascia arranges waterproof tongue and groove, one
Aspect is unfavorable for the transport of exterior wall internal partition, and is transporting or easily causing during construction the destruction of waterproof tongue and groove, and should
Mode is not appropriate for external wall insulation and the assembling of decoration panel, for Side fascia warming plate, during docking
Easily knock the bad heat-insulation layer part as tongue and groove tenon, thus affect waterproof effect, for decoration panel, owing to offering
Tongue-and-groove, the architectural surface of the end of decoration panel isolates and comes, easily knocks bad in transport and docking operation, repairs difficulty, seriously
Affect attractive in appearance.
In sum, need exploitation badly a kind of simple, highly versatile, the Side fascia waterproofing node of good water-proof effect.
