Example 1:
referring to fig. 1, a waterproof structure at the seam of an assembled side fascia is shown. Preferably, the joints formed by the assembled external wall panels 4 are less than or equal to 20mmm.
The waterproof structure of the present invention includes a primary waterproof structure 1, a decompression cavity structure 2, and a secondary waterproof structure 3.
The primary waterproof structure 1 is arranged at the outer end of the seam formed by each assembled external wall panel 4, and the secondary waterproof structure 3 is arranged at the inner end of the seam formed by each assembled external wall panel 4. The water isolation of the seam is carried out through the primary waterproof structure 1 and the secondary waterproof structure 3.
Preferably, the primary waterproof construction 1 comprises weather-resistant waterproof silica gel 5 and foam strips 6. The foam strips 6 are arranged at the outer ends of the joints formed by the assembled external wall boards 4, and the weather-proof waterproof silica gel 5 is filled in the joints and covers the outer sides of the foam strips 6. The weather-proof waterproof silica gel 5 and the foam strips 6 are arranged to prevent the outer wall water body from penetrating into the seam.
Further, the primary waterproof structure 1 further comprises a drainage conduit 7, and the drainage conduit 7 is arranged to penetrate through the weather-proof waterproof silica gel 5 and the foam strip 6.
Further, the water outlet end of the water drainage conduit 7 is arranged obliquely towards the ground. The water body permeated into the seam can be discharged outwards through the drainage conduit 7, so that the water body is prevented from permeating into the inner side of the wall body.
Preferably, the secondary waterproof construction 3 comprises polyurethane 9 and two pre-embedded rubber waterstops 8. The two pre-embedded rubber water stops 8 are arranged at the inner ends of the splice joints formed by the assembled external wall boards 4 and are mutually extruded and anastomosed, so that the water blocking function is achieved.
And polyurethane 9 fills in the seam and covers in the embedded rubber waterstop 8 inboard, further strengthens the waterproof performance of secondary waterproof structure 3.
Preferably, the pre-embedded rubber water stop belt 8 is pre-embedded in the casting concrete when the assembled external wall panel 4 is prefabricated in a factory.
Preferably, the pressure relief cavity construction 2 is provided with a central end of the seam formed by each of the assembled side fascia panels 4. And the decompression cavity structure 2 is composed of a groove structure and a seam space which are oppositely arranged.
Further, the two groove structures in the decompression cavity structure 2 are respectively arranged on the side walls of the adjacent assembled external wall boards 4.
Furthermore, the bottom space-seam space of the two groove structures in the decompression cavity structure 2 is more than 18mm, so that the decompression cavity structure 2 is ensured to have a sufficiently large decompression chamber.
The decompression cavity structure 2 forms an enlarged cavity in the joint formed by the assembled external wall panels 4, so that the decompression treatment of the water body after the primary waterproof structure 1 is realized, the direct impact of the corresponding water body or the penetration of the water body into the secondary waterproof structure 3 through capillary is avoided, and the service life of the secondary waterproof structure 3 is ensured.
Through the structural design of the decompression cavity structure 2, the decompression cavity structure 2 can block or collect water bodies passing through the primary waterproof structure 1, so that corresponding water bodies are collected in cavities in the decompression cavity structure 2 and flow in the ground direction directly until being led out, and the water bodies are not immersed in the secondary waterproof structure 3 continuously.
For the waterproof solution of the assembled building, the water guide is better than the water blocking and the water drainage is better than the water prevention. The waterproof structure at the joint of the assembled external wall panel solves the quality common problem of serious water seepage of the assembled external wall through the waterproof structure of the three functions of guiding, dredging and preventing. After the waterproof construction of the assembly type outer wall joint is finished, the hidden leakage trouble of the outer wall joint is greatly reduced, and the assembly type outer wall joint is economical, reasonable, safe and reliable.
Example 2
On the basis of embodiment 1, this embodiment also discloses: the waterproof method for the joint of the assembled external wall boards comprises the step of arranging the waterproof structure in the embodiment 1 at the joint between the assembled external wall boards 4 in the process of splicing and installing the assembled external wall boards 4.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
