Be sticked water-swellable sealing joint strip 5 in water groove 4, then by upper prefabricated components 6（I.e. upper dry wall）It is lifted on lower prefabricated components 1
（Descend dry wall）On, make prefabricated components 6（I.e. upper dry wall）With lower prefabricated components 1（Descend dry wall）Docking forms waterproof
Tongue and groove 3；
3）Cleaning treatment is carried out to the lateral surface piece interface of upper prefabricated components 6 and lower prefabricated components 1, clogs packing material, and
Waterproof gasket cement 2 is injected to the brush primary coat of gluing interface, then to gluing interface；
4）Fluid sealant is applied to the lateral surface of upper prefabricated components 6 and lower prefabricated components 1 and carries out water repellent treatment.
Embodiment 2
With reference to Fig. 3, a kind of prefabricated components piece waterproof construction of the present embodiment, compared with Example 1, there are following differences：
Waterproof groove 4 is longitudinally extended along dry wall upper surface（Extend along the direction of upper surface longer sides, wall as shown in Figure 3
Plate level length direction）It is curvilinear.
What the waterproof groove 4 that curved shape extends was conducive to generate dry wall when the expansion by water-swellable sealing joint strip 5
Active force disperses, and then avoids causing stress on a certain section of dry wall strong because of the excessive expansion of water-swellable sealing joint strip 5
The phenomenon that degree increased dramatically and damage dry wall base material.
1 lateral surface of prefabricated components is tilted down and is set 31 opposing transition surfaces 32 of outer tongue and groove face of the lower prefabricated components 1 downward
It sets.Specifically, the transition face 32 of the lower prefabricated components 1 is vertically arranged, and outer tongue and groove face 31 tilts down extension, in this way, outer tongue and groove
Face 31 is guide face, and the water entered in upper and lower prefabricated components gap is made to flow downward under the effect of gravity, to further carry
The effect of high water resistance.
A kind of construction method of prefabricated components piece waterproof construction of the present embodiment is the same as embodiment 1.
Embodiment 3
With reference to Figure 4 and 5, a kind of prefabricated components piece waterproof construction of the present embodiment, compared with Example 1, there are following differences：
According to the thickness and waterproof requirement of prefabricated components, the quantity of the waterproof groove 4 is two.
A kind of construction method of prefabricated components piece waterproof construction of embodiment, includes the following steps：
1）Lower prefabricated components production 1（Descend dry wall）When, in lower prefabricated components 1（Descend dry wall）Upper surface it is default together
Waterproof groove 4；
2）To lower prefabricated components 1（Descend dry wall）Waterproof groove 4 on the interior tongue and groove face 33 on top carries out removing surface, anti-
Be sticked water-swellable sealing joint strip 5 in water groove 4, then by upper prefabricated components 6（I.e. upper dry wall）It is lifted on lower prefabricated components 1
（Descend dry wall）On, make prefabricated components 6（I.e. upper dry wall）With lower prefabricated components 1（Descend dry wall）Docking forms waterproof
Tongue and groove 3；
3）Cleaning treatment is carried out to the lateral surface piece interface of upper prefabricated components 6 and lower prefabricated components 1, clogs packing material, and
Waterproof gasket cement 2 is injected to the brush primary coat of gluing interface, then to gluing interface；
4）Fluid sealant is applied to the lateral surface of upper prefabricated components 6 and lower prefabricated components 1 and carries out water repellent treatment.
The present invention a kind of prefabricated components piece waterproof construction, transition face 32 can also be serrated face or arc-shaped curved surface, i.e.,
When transition face 32 is in serrated face, then the contour line in its section is broken line；Or when transition face 32 is arc-shaped curved surface, then its section
Contour line is curve, further improves the water resistance of dry wall.
After the completion of assembly, rainwater on the outside of prefabricated panel easily enters from the gap between adjacent dry wall, when rainwater into
When entering gap, transition face 32 mainly plays barrier effect, makes rainwater that can not move on, the transition of serrated face or arc-shaped curved surface makes
The space of the receiving rainwater with bigger, compares the transition face 32 of plane formula, has more preferably waterproof between contiguous prefabricated wallboard
Performance.
In order to further increase the water resistance of waterproof construction, the both ends of transition face 32 are also provided with D font marine glues
Head or polyethylene foam stick, when upper and lower prefabricated components are in lifting, the both ends of transition face 32 are equipped with D font waterproof rubber heads or poly-
Ethylene foaming stick can buffer impact force between the two, can also delay the infiltration of water in upper and lower prefabricated components gap, improve
Its water resistance.
The waterproof groove 4 is along lower prefabricated components 1（Such as dry wall）Upper surface is longitudinally extended（I.e. along upper surface longer sides
Direction extends）In fold-line-shaped（Such as zigzag）, to lower prefabricated components 1 when being conducive to disperse the expansion of water-swellable sealing joint strip 5
（Such as dry wall）The active force of generation, and then avoid leading to lower prefabricated components 1 because of the excessive expansion of water-swellable sealing joint strip 5
（Such as dry wall）Stress intensity increased dramatically on a certain section, and then damage lower prefabricated components 1（Such as dry wall）The phenomenon that base material.
The cross section of the waterproof groove 4 is in inverted trapezoidal or V-groove, convenient for different in it to being placed in waterproof groove 4
The limit of the water-swellable sealing joint strip 5 of size is fixed.
The present invention a kind of prefabricated components piece waterproof construction, apply also for prefabricated components be precast beam and under prefabricated structure
Part is prefabricated panel or upper prefabricated components are seam between prefabricated panel and prefabricated components that lower prefabricated components are precast beam
Gap, the modification of said program, those skilled in the art are appreciated that and are implemented by explanatory note, the application just no longer attached drawing into
Row repeats.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
