Description
Technical Field
The utility model belongs to the technical field of building sandwich heat preservation wall, especially, relate to a waterproof connected node structure of prefabricated side fascia of assembly type structure.
Background
In the assembly type building industry, the external wall panel is produced in a factory in a prefabricated mode and then assembled on site, so that standardization can be realized, quality can be controlled, and high efficiency and rapidness are realized. However, during the field assembly process of the prefabricated external wall panel, the spliced part of the prefabricated external wall panel is subjected to waterproof treatment, rainwater is prevented from permeating into the interior of the room along the spliced seam of the external wall panel, meanwhile, if the water seepage phenomenon is serious, the connected part is loosened, the effective bearing capacity of the prefabricated external wall is reduced due to long-term use, and great engineering hidden danger is brought. The traditional external wall panel is usually waterproof glue applied to the joint, so that the construction workload is large, the waterproof glue can age along with the long time, and finally the water leakage phenomenon is caused, and the waterproof performance and the building quality of the fabricated building are influenced.
At present, the outer wall panel is usually waterproof by adopting a rabbet, namely, a joint of the wall panel is provided with a waterproof rabbet with a high inner side and a low outer side, so that outdoor rainwater is prevented from leaking indoors, and the existing outer wall panel is waterproof by adopting the mode in the application technical specification; in the prior art, patent 205116466U discloses a waterproof structure of an assembled building outer wall dry-hanging node, in which a waterproof tongue-and-groove with a height difference of inside height and outside height is molded at the joint of the upper end of a lower prefabricated dry-hanging outer wall panel and the lower end of an upper prefabricated dry-hanging outer wall panel for waterproof treatment. However, after the waterproof rabbet is arranged on the outer wall board, the transportation of the inner partition board of the outer wall board is not facilitated, the waterproof rabbet is easy to damage in the transportation or construction process, the rabbet part is easy to damage in the butt joint process, and therefore the waterproof effect is affected.
In summary, it is highly desirable to develop a waterproof connection node structure for an external wall panel, which is simple and feasible, has strong versatility, good waterproof effect, and simple production mold.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the not enough of above-mentioned prior art, invented an assembly type structure prefabricated external wall panel waterproof connection node structure.
In order to achieve the above object, the utility model adopts the following technical scheme:
a waterproof connecting joint structure of an assembly type building prefabricated external wall panel comprises an external wall panel, transverse grooves, connecting strips and vertical grooves, wherein the transverse grooves are formed in the middle line positions of horizontal joints of the external wall panel; the connecting strip is arranged in the transverse groove and is used for connecting the upper external wall panel and the lower external wall panel; and vertical grooves are formed in vertical joints of the external wall panels.
The utility model discloses an innovation point lies in linking together two piece upper and lower side fascia and realizing water-proof effects through adopting the connecting strip, and the water of outside internal infiltration can be blockked and discharge along the vertical recess of horizontal recess flow direction by the connecting strip.
Further, the width of the transverse groove is 2-3cm, and the preferred width is 3 cm.
