A waterproof structure is arranged in the joint 140, the waterproof structure comprises a first waterproof part 120, a second waterproof part 130 and a water absorption part 103, and the waterproof structure is matched with the joint 140, namely, the mutual matching of material waterproofing and structural waterproofing is realized, which is beneficial to improving the waterproof performance of the joint of the prefabricated slab 101.
The utility model discloses technical scheme is through setting up waterproof construction in prefabricated plate 101 seam crossing, because be formed with seam 140 between the prefabricated plate 101, rivers can be indoor through this seam 140 infiltration, consequently set up waterproof construction in seam 140 department, can improve the waterproof performance of prefabricated plate 101 seam crossing, this waterproof construction is including the waterproof portion of multichannel, the waterproof portion of multichannel cooperates with seam 140, can effectually play the hindrance effect to rivers, the biggest restriction rivers permeate indoorly, the service function to improving the durability of prefabricated plate 101 structure and ensureing the building has important meaning.
In this embodiment, referring to fig. 2, the seam 140 includes a normal pressure drainage cavity 142 extending along a horizontal direction, the normal pressure drainage cavity 142 communicates the outdoor end 141 and the indoor end 143, and the water absorption portion 103 is disposed in the normal pressure drainage cavity 142; the outdoor end 141 is inclined upward in a direction toward the atmospheric drain chamber 142, and/or the indoor end 143 is inclined downward in a direction toward the atmospheric drain chamber 142.
Specifically, seam 140 includes normal pressure drainage chamber 142, outdoor end 141 and indoor end 143, outdoor end 141 is for being close to outdoor one end, indoor end 143 is for being close to indoor one end, be provided with normal pressure drainage chamber 142 between outdoor end 141 and the indoor end 143, the normal pressure drainage chamber 142 about both ends respectively with outdoor end 141 and indoor end 143 intercommunication, known by fig. 2, outdoor end 141 is the contained angle setting with the horizontal direction, indoor end 143 also is the contained angle setting with the horizontal direction, forms corresponding slope, and this slope makes seam 140 possess certain waterproof ability for 2% -5% with horizontal direction contained angle scope.
Further, the first waterproof portion 120 includes a first sealing body 122 disposed at the outdoor end 141, a backing material 121 is disposed on a side of the first sealing body 122 away from the outdoor end 141, and the first sealing body 122 is formed by a sealant.
Specifically, the first waterproof unit 120 is provided in the outdoor end 141, the first waterproof unit 120 includes a first sealing body 122 provided in the outdoor end 141, a backing material 121 is provided at one end of the first sealing body 122 near the atmospheric water discharge chamber 142, and the backing material 121 is provided with a deformable material for controlling the caulking depth of the first sealing body 122 and preventing the first sealing body 122 and the bottom of the joint from being bonded.
The first sealing body 122 is filled in the outdoor end 141 and is respectively connected with the upper prefabricated plate 101 and the lower prefabricated plate 101 which are adjacent to each other, and the first sealing body 122 is made of sealing glue, so that the sealing glue has certain sealing property and waterproof property, and the outdoor end 141 is obliquely arranged, so that the sealing glue can prevent water from penetrating into the seam 140 to the maximum extent at the outdoor end 141.
Referring to fig. 3, the second waterproof portion 130 includes steel nails 132 and water stop strips 131, two ends of the steel nails 132 are respectively abutted to two adjacent prefabricated panels 101, and the water stop strips 131 are inserted into the steel nails 132.
The water stop strip 131 is a rubber water stop strip. Because the water stop strip 131 is made by mixing polyurethane material and rubber, wherein the polyurethane material has hydrophilicity, when the water stop strip 131 is soaked in water, the hydrophilic group in the water stop strip 131 is combined with hydrogen bonds, so that the acting force between molecules of the water stop strip 131 is weakened, the volume of the water stop strip 131 is increased, the indoor end 143 is blocked, and water flow is prevented from permeating into a room.
Referring to fig. 3, the second waterproof portion 130 further includes a second sealing body 133, the second sealing body 133 is located on a side of the water stop bar 131 away from the outdoor end 141, a waterproof coating 102 is disposed on a side of the second sealing body 133 away from the water stop bar 131, and the second sealing body 133 is formed by polymer cement mortar; the waterproof coating 102 is made of polymer cement-based waterproof paint or polyurethane waterproof paint.
It can be understood that, since the second waterproof section 130 is disposed at the indoor end 143, the second waterproof section 130 includes a steel nail 132 disposed between two adjacent prefabricated panels 101, a water stop 131 is penetrated through the steel nail 132, and a side of the water stop 131 away from the outdoor end 141 is filled with a second sealing body 133, the second sealing body 133 is made of polymer cement mortar, and the second sealing body 133 is tightly filled between the adjacent prefabricated panels 101, when water flows to the position of the water stop 131, the water stop 131 immediately swells when it meets water, and the indoor end 143 is completely blocked, preventing water from penetrating into the indoor through the indoor end 143 due to the self-swelling property of the water stop 131.
Further, a containing groove 109 is formed in the bottom of the normal pressure drainage cavity 142, the containing groove 109 is communicated with the normal pressure drainage cavity 142, and the water absorbing portion 103 is contained in the containing groove 109.
It should be noted that the normal pressure drainage cavity 142 is respectively communicated with the outdoor end 141 and the indoor end 143, so that water flow must pass through the normal pressure drainage cavity 142 before penetrating into the second waterproof portion 130, and therefore, the accommodating groove 109 is disposed at the bottom of the normal pressure drainage cavity 142, and the accommodating groove 109 is filled with a water absorbing material, so as to stabilize the waterproof performance of the waterproof structure.
Specifically, the water absorption portion 103 is a bentonite rubber water stop. Because the swelling rate of the bentonite rubber water stop strip can reach 400-500% after meeting water, the bentonite rubber water stop strip can be filled in the accommodating groove, has certain water absorption, can evaporate water under the condition of no rainwater, recovers the original shape, and cannot influence the quality of the bentonite rubber water stop strip under the condition of repeated swelling, a large amount of water flow is prevented from permeating into the second waterproof layer, the impermeability and the waterproofness of the waterproof structure are improved, and the durability of the prefabricated plate 101 is improved.
It should be noted that the depth of the receiving groove 109 is h, where h is 50mm, because the expansion rate of the commercially available (10 × 20) bentonite rubber sealing strip is 400% -500%, the receiving groove can be filled up after the bentonite rubber sealing strip absorbs water and expands, and the normal pressure drainage cavity 142 is not blocked. When h is less than 50mm, the depth of the accommodating groove 109 is smaller, and the bentonite rubber water stop strip exceeds the range of the accommodating groove 109 after expanding with water; when h is greater than 50mm, because the receiving groove 109 is disposed in the lower prefabricated panel 101, the structure of the prefabricated panel 101 may be unstable when the depth of the receiving groove 109 is too large.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
