As shown in fig. 3, the waterproof layer 4 is covered with a cover seam plate 30, the cover seam plate 30 is preferably an aluminum alloy plate with a thickness of 1mm, and may be a plate with other thickness or material, such as a stainless steel plate, etc., the cover seam plate 30 covers the whole top surfaces of the first partition 8 and the second partition 9, the area directly above the expansion joint is bent into a triangle, meanwhile, two ends of the cover seam plate 30 are fixed at the side 81 of the first partition and the side 91 of the second partition, and when fixed specifically, the two ends of the cover seam plate 30 can be fixed by stainless steel nails 50 embedded into the roof floor 11, and at this time, as the stainless steel nails 50 may penetrate through the waterproof paint layer 13 and the high polymer modified asphalt waterproof coiled material 14, leakage may occur, and therefore, the waterproof glue layer 60 is covered on the periphery of the stainless steel nails 50.
In another embodiment, in order to prevent water from penetrating into the stainless steel nails from the bottom of the cover slit plate 30, as shown in fig. 4, the two ends of the cover slit plate 30 are bent toward the side 81 of the first partition body and the side 91 of the second partition body, and corresponding inclined grooves 82 and 92 are formed at the side 81 of the first partition body and the side 91 of the second partition body, and when the cover slit plate is assembled, sealing rings or other sealing materials are filled in the inclined grooves 82 and 92, and the bent parts 301 and 302 at the two ends of the cover slit plate 30 are inserted into the inclined grooves 82 and 92, so that the waterproof performance is effectively improved.
Of course, in other embodiments, the two ends of the seam cover 30 may be glued to the side of the first partition and the side of the second partition by waterproof glue or the like.
Further, as shown in fig. 5, in order to protect the first drainage ditch 6 and the second drainage ditch 7 and facilitate the traffic, hollow cover plates 60 are provided on the first drainage ditch 6 and the second drainage ditch 7, and the hollow cover plates 60 may be known various feasible cover plates, such as cast iron cover plates, concrete cover plates, etc., which are erected on the first drainage ditch 6 and the second drainage ditch 7 through supporting members 70.
As shown in fig. 5, the supporting member 70 includes two oppositely disposed members, one of which is fixed at the top angle position of the fine stone waterproof layer near the drainage ditch, and the other of which is fixed at the top angle position of the protective cap, each member includes a tip 701 welded integrally, an angle iron 702 and a supporting plate 703, the tip 701 is embedded in the fine stone waterproof layer 16 or on the top plate of the protective cap, two flat plates of the angle iron 702 are positioned at the top angle positions of the fine stone waterproof layer 16, the supporting plate 703 is positioned in the first drainage ditch and the second drainage ditch, one flat plate is parallel to the horizontal plane, and a fixing hook 704 is arranged on the flat plate of the supporting plate 703 in a gap, thereby facilitating the installation of the filter screen below the hollow cover plate 60.
In addition, in order to reduce the risk of infiltration of the water in the drainage ditch into the expansion joint 3, the water discharge opening of the first drainage ditch 6 is positioned at one side of the drainage ditch, which is deviated from the first side wall 201, the water discharge opening of the second drainage ditch 7 is positioned at one side of the drainage ditch, which is deviated from the second side wall 202, and the bottoms of the first drainage ditch 6 and the second drainage ditch 7 respectively find 1% of longitudinal slopes for the water discharge openings thereof.
The protective cap 20 may be integrally built, but the structure of such a masonry is not resistant to deformation at the expansion joint, and thus is likely to itself be cracked or damaged, and once damaged will not be protective, in that, in other embodiments, the top plate 203 is in the form of a fitting, and the thickness of the top plate 203 is not less than 50mm, not more than 100mm, preferably between 80±5 mm.
Specifically, as shown in fig. 6 and fig. 7, the top plate 203 of the protective cap 20 includes a first plate 2031 and a second plate 2032, opposite end surfaces of the first plate 2031 and the second plate 2032 are formed into a clamping groove 2033 and a protruding block 2034 that are matched, a compression-deformed silica gel sealing strip 2035 is disposed in the clamping groove 2033, and top surfaces of the first plate 2031 and the second plate 2032 are covered with a waterproof surface layer 2036, and after the assembly is completed, a seam at the top of the first plate 2031 and the second plate 2032 is sealed by sealant.
At this time, even if the expansion joint 3 generates a translational motion, a certain translational motion can be generated between the first plate 2031 and the second plate 2032, so that the damage of the whole structure can be avoided, and meanwhile, the silica gel sealing strip 2035 between the first plate 2031 and the second plate 2032 can still play a role in waterproof.
As shown in fig. 7, in order to further increase the waterproof performance, a flexible waterproof layer 2039 covering the top surfaces of the first plate 2031 and the second plate 2032 is disposed below the waterproof surface layer, and when in construction, the first plate 2031 and the first plate 2032 may be covered by the flexible waterproof layer 2039, and then the waterproof surface layer 2036 may be constructed on the flexible waterproof layer 2039.
In addition, since the protective cap has a bearing function in addition to a protection function, and when the above-mentioned assembly structure is adopted, the bearing capacity of the top plate 203 is relatively weak, so in order to increase the bearing capacity of the top plate 203, as shown in fig. 7, at least one supporting plate 2037, 2038 abutting against the top surfaces of the first partition portion 8 and the second partition portion 9 is respectively and vertically arranged at the bottom of the first plate 2031 and the second plate 2032.
Meanwhile, the first plate 2031 and the second plate 2032 may be integrally built with the first side wall 201 and the second side wall 202, or may be assembled by an assembly structure, and when the assembly structure is adopted, corresponding connection holes are formed in the first plate 2031, the second plate 2032, the first side wall 201 and the second side wall 202, respectively, and are assembled by bolts; of course, it may be assembled into a whole by glue, concrete, or the like.
Finally, the first side wall 201 and the second side wall 202 may be built together with the bottom 7 of the first drainage ditch 6 and the second drainage ditch, and as shown in fig. 8, raised strips 62 and 72 may be further provided on the fine stone waterproof layers 61 and 71 of the bottoms of the first drainage ditch 6 and the second drainage ditch 7, and at the same time slots 2011 and 2021 matching with the raised strips 62 and 72 are formed on the bottom surfaces of the first side wall 201 and the second side wall 202, and when assembling, sealing elements or sealing paste 80 may be provided on the bottoms of the slots 2011 and 2021, so that the waterproof capability of the joints between the first side wall 201 and the second side wall 202 and the bottom 7 of the first drainage ditch 6 and the second drainage ditch may be effectively improved.
Of course, the first side wall 201 and the second side wall 202 may be connected to the bottoms 7 of the first drainage ditch 6 and the second drainage ditch in a threaded manner, for example, when in a threaded manner, a groove may be formed in the fine stone waterproof layer, and the expansion bolts penetrate through the top plate 203, the side walls 201 and 202 and are embedded into the groove, at this time, the joints between the first side wall 201 and the second side wall 202 and the bottoms 7 of the first drainage ditch 6 and the second drainage ditch may be treated in the above manner.
The invention has various embodiments, and all technical schemes formed by equivalent transformation or equivalent transformation fall within the protection scope of the invention.
