Description
Technical field
The utility model belongs to architectural engineering sealing protection technical field, and in particular to a kind of industrialized building joint seal
Waterproof construction.
Background technology
Large number of seam is will produce after assembled PC external walls hanging plate or Exterior Wall Components splicing, inevitably
Encounter the problem of seam waterproof processing.In JGJ 1-2014《Prefabricated concrete structure technical regulation》In the 5.3.4 articles regulation：
" waterproofs such as the seam of prefabricated outer wall panel and door-window opening weak part preferably uses what material waterproofing and constructional waterproofing be combined to do
Method ".
The prefabricated outer wall panel seam waterproof form generally used in practice at this stage mainly has following two：
（1）The prefabricated outer wall panel (i.e. PCF plates) of inner deposited and outer hung mainly uses outside draining cavity and gluing, inside to rely on existing
Pour the seam waterproof form of part concrete self-waterproof.This Side fascia seam waterproof form is current with a kind of most shapes
Formula, its benefit are that simpler speed of constructing is fast, the disadvantage is that waterproof quality is difficult to control, cavity stopping state happens occasionally,
Once cracking, which occurs, for inside concrete directly results in the failure of wallboard waterproof.This mode is gradually eliminated.
（2）The closed line waterproof form that external hanging type prefabricated outer wall panel uses.This wallboard waterproof form mainly has 3 to prevent
Water measure, it is the pressure reduction space that physics cavity is formed that outermost, which uses the weather-proof water-proof silica-gel of high-tension, middle section, and inside makes
It is compressed mutually up and down to play waterproof effect, at the cruciform joint between metope with the water proof rubber bar in advance in concrete
It is further added by one of fluid sealant waterproof except rubber fastening band, is set at one on exterior wall water-proof silica-gel every 3 layers or so of distances
The rainwater for penetrating into pressure reduction space effectively can be directed to outdoor by drainpipe.In the water proof structure of closed line waterproof uses
Outer three waterproof dredges the stifled method being combined, and water proof structure is very perfect, therefore waterproof effect is also very good, disadvantage
Required precision is very high when being construction, otherwise wallboard dislocation, which cannot be more than 5mm, can not compress watertight rubber item, and the weather-proof of use is prevented
The performance requirement of glue is relatively high.
When construction, loose porous for concrete surface, effective bond area reduces and component surface is stained with releasing agent
The problems such as, Seal Design has used primary coat processing, water-fast to improve fluid sealant and concrete binding power, closing dust and raising
Property.
Above-mentioned design and construction measure improves joint seal quality and waterproof effect, but according to industrialized building industry
So far engineering seam waterproof situation in 2005, seam infiltration is at common fault, the assembly of the cities 2013-2015 Nian Duimou of certain construction engineering group
Formula is built（Prefabricated rate 16%-30%）Seam leakage scenarios are investigated, and seam seepage control leakage passed examination rate of quality only has
84.8%（Highest 86%）, by the comprehensive improvements measure such as structural design optimization, assembling Quality Control, but still have 5% or more seam
There are leakage hidden troubles.In addition, the limitation of industrialized building prefabricated panels technique, installations and facilities etc. more leads to jigsaw matrix surrounding
Seam quality is difficult to reach the intensity of design requirement, rigidity and compactness, while also easily in production, transport and assembling process
By breakage, not only the waterproof water-resisting ability of its own is insufficient, but also the capillary siphon side effect itself brought can cause seam outer
Moisture, tube chamber mobile moisture can be infiltrated along concrete surface layer, be spread, and do not only resulted in and blocked water unsuccessfully, can also be led under long-term etch
Surface layer's concrete aging, charing and dusting are caused, causes seal failure so as to cause more serious leakage problem, to industrialization
Building shapes up brings very big puzzlement with living standards of the people and Quality advance and guarantee.
Based on the above issues, it is necessary to invent a kind of industrialized building joint waterproofing structure to utilize sealing and dredge
Water, the comprehensive function to block water ensure that waterproof construction is weather-proof for a long time, sealing waterproof is reliable, so that it is guaranteed that building joint protects waterproof
Quality prevents seam flow and penetrates into interior, has good economic and social profit.

Layer, jigsaw b removing surface layers, jigsaw b matrixes.The outer surface of the waterproof sealing glue-line is equipped with one layer of decoration protective layer.It is described
The roughness of jigsaw a removing surfaces layer and jigsaw b removing surface layers is 30-50 μm, the jigsaw a removing surfaces layer and jigsaw b
The range of removing surface layer includes horizontal joint, vertical seam, ribbet faulting of slab ends and cavity surface.The jigsaw a surface water-repellent layers and spelling
Plate b surface water-repellent layers are hydrophobic silane coatings, spraying dipping depth 1-2mm, and the hydrophobic silane coating range covers including water
Flush joint, vertical seam, ribbet faulting of slab ends and cavity surface.Jigsaw a surface priming coats and the surfaces jigsaw b priming coat are that assembled is built
The special primary coat product of building waterproofing fluid sealant, primer thickness are 10-30 μm, and the priming coat ranging from seam both sides need to seal
The surface of bonding.
The beneficial effects of the utility model：The utility model ensure that anti-using sealing and comprehensive function that is hydrophobic, blocking water
Water-bound is weather-proof for a long time, sealing waterproof is reliable, so that it is guaranteed that building joint protects waterproof quality, prevents seam flow and gos deep into room
It is interior, there is good economic and social profit.
