[0023] Embodiment 1
[0024] As Figure 1 shown, the embodiment discloses a kind of assembled prefabricated wallboard with high waterproof sealing, including first wall 100, second wall 200, sealing assembly. First wall 100 with second wall 200 are prefabricated wall, and they are connected by bolt, and there is small joint between first wall 100 and second wall 200. Sealing assembly is arranged in the joint of first wall 100 and second wall 200 connection gap. Sealing assembly includes first sealing unit, second sealing unit and third sealing unit, first sealing unit is arranged in joint and is located the position close to first wall 100 and second wall 200 outside, third sealing unit is arranged in joint and is located the position close to first wall 100 and second wall 200 inside, second sealing unit is arranged in joint and is located the position close to first wall 100 and second wall 200 intermediate. That is, first wall 100 and second wall 200 between joint are provided with three waterproof sealing measures, to improve its sealing property advantageously.
[0025] Among them, second sealing unit uses elastic sealing material, and its two side surfaces that contact with first wall 100 and second wall 200 are the shape of protrusion and groove alternation (similar to wave shape). Under the action of bolt connection, first wall 100 and second wall 200 extrude second sealing unit arranged in joint, second sealing unit occurs elastic deformation, the form of protrusion and groove alternation of its two side surfaces can occur greater deformation, to effectively fill the unevenness of first wall 100 and second wall 200 and second sealing unit contact surface microscopically, to further increase its sealing property.
[0026] As Figure 2As shown, the interior of the second sealing unit is porous. The porous elastic material generates internal stress when compressed and deformed, thereby increasing the extrusion force between the second sealing unit and the first and second walls 100, 200. Combined with the alternating protrusions and grooves on both sides of the second sealing unit, the second sealing unit can effectively fill the microscopic irregularities on the contact surfaces between the first and second walls 100, 200, and the second sealing unit under the action of the extrusion force, preventing liquid from flowing in the contact gaps, thereby achieving the purpose of sealing and waterproofing.
[0027] Specifically, the second sealing unit uses EPDM elastic rubber sealing strip 400. EPDM rubber has excellent aging resistance, high and low temperature resistance, and excellent corrosion resistance to chemicals and acid and alkali resistance. The material's durability can meet the design service life requirements of the building structure. It also serves to fill gaps, absorb / reduce vibration, isolate noise, and prevent moisture from penetrating into the room.
[0028] Optionally, during assembly, both sides of the second sealing unit are first pre-bonded to the first wall 100 and the second wall 200 using a sealing adhesive. Then, the first wall 100 and the second wall 200 are tightened using bolts, thereby squeezing the second sealing unit so that the second sealing unit deforms and fills the gap between the first wall 100 and the second wall 200.
[0029] In this embodiment, the first sealing unit and the third sealing unit both include a filler and a sealant 300. The filler is filled in the joint, and the sealant 300 is coated on the filler to seal.
[0030] Specifically, the filler is a foam strip 310, and the sealant 300 is made of MS-modified silicone. The first sealing unit is positioned near the joint between the first wall 100 and the outside of the second wall 200. The foam strip 310 fills the joint, and the sealant 300 is applied to the foam strip 310. The third sealing unit has the same structure as the first sealing unit and will not be described in detail here.
[0031] like Figure 1 As shown, the first wall 100 is provided with a first embedded part 500, which is a connecting box, and the second wall 200 is provided with a second embedded part 510, which is an embedded sleeve. The embedded sleeve is provided with an internal thread, and the bolt in the connecting box is connected to the embedded sleeve through a thread to provide a fastening force between the first wall 100 and the second wall 200, thereby squeezing the sealing assembly.
[0032] The assembled prefabricated wallboard with high waterproof sealing performance in the embodiment is provided with three waterproof sealing measures in the joint between the first wall body 100 and the second wall body 200, in addition to the first sealing unit and the third sealing unit on the two sides, the EPDM sealing strip 400 is arranged in the middle of the joint, and the two side surfaces of the EPDM sealing strip 400 in contact with the first wall body 100 and the second wall body 200 are in the shape of protrusions and grooves alternately, when the second sealing unit is extruded, the two side surfaces are deformed, and the micro concave-convex on the contact surface of the first wall body 100 and the second wall body 200 with the second sealing unit can be effectively filled, so that the sealing performance is increased. In combination with the porous structure inside, the extrusion deformation force of the EPDM sealing strip 400 can be increased, so that the sealing performance is further increased.
[0033] The assembled prefabricated wallboard with high waterproof sealing performance in the embodiment forms a "one main and one auxiliary" wallboard longitudinal joint waterproof system process with the EPDM sealing strip 400 and the MS modified silicone sealant 300, so that the construction quality is easier to control and inspect, and the construction measures are safer and simpler.
[0034] It can be understood that the above implementation is only an exemplary implementation for illustrating the principle of the utility model, and the utility model is not limited thereto. For ordinary skilled persons in the art, various modifications and improvements can be made without departing from the spirit and essence of the utility model, and these modifications and improvements are also regarded as the protection scope of the utility model.
