[0007] Step three, one-side cantilever cover plate and settlement joint plugging, after the one-side cantilever cover plate is maintained to reach the design strength, the formwork is removed and cleaned, and then the one-side cantilever cover plate and the reverse ridge top are injected with the building sealant for plugging after drying

[0008] Step four, setting of the waterproof layer, a layer of waterproof layer is covered on the formed one-side cantilever cover plate, so as to improve the overall waterproof effect.

[0009] Further, in the step one, the height of the settlement joint reverse ridge after the formwork installation is greater than or equal to 200mm.

Therefore, the features defined as “first”, “second” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of those skilled in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the application.

[0018] Reference Figures 1-3In the present application, a construction method for preventing leakage of a roof settlement joint comprises the following steps: Step 1, roof measurement and line laying, after completion of roof scaffold support and template installation, measurement and positioning of roof water and electricity pre-burial and settlement joint position are carried out, and at the same time, in order to ensure one-time forming of the roof and the main structure of the settlement joint, roof reinforcement and settlement joint reinforcement are bound, and one-side overhanging cover plate reinforcement is pre-buried, after pre-burial of water and electricity, formwork installation of the settlement joint is carried out; the settlement joint is installed by formwork, after installation of the formwork, the height of the settlement joint counterfort is greater than or equal to 200 mm, and the reinforcement is completely installed and the water and electricity pre-burial is completed, after completion of the formwork installation, acceptance is carried out, and after acceptance, roof concrete is poured.

[0019] Step 2, one-side overhanging cover plate template installation, one-side overhanging cover plate 4 template is installed, the one-side overhanging cover plate 4 is arranged on the overhanging support 5, and the slope from the root part B to the end part A is arranged, the root part and the end part are arranged with a drip line, the drip line comprises an overhanging end drip line 1 and an overhanging support drip line 2, then reinforcement is made, template installation is completed, cover plate concrete is poured, and C30 fine stone concrete is used for pouring of the concrete. The one-side overhanging cover plate solves the problem of cracking and leakage caused by uneven settlement of two buildings in the traditional concrete cover plate; the principle of the one-side overhanging cover plate is to both block rain by the cover plate and completely separate the two buildings without any connection, so as to achieve the purpose of preventing cracking and leakage; the one-side overhanging cover plate solves the drawbacks of leakage caused by warping deformation of the traditional metal cover plate, so as to achieve the purpose of preventing cracking and leakage; and the cost of the cast-in-place one-side concrete cover plate is much lower than the procurement and installation cost of the metal cover plate, so as to achieve the purpose of cost saving.

[0020] Step 3, sealing of the one-side overhanging cover plate and the settlement joint 7, after the one-side overhanging cover plate reaches the design strength after maintenance, the formwork is removed and cleaned, and after drying, the one-side overhanging cover plate and the counterfort top are injected with building sealant 3 for sealing.

[0021] Step 4, setting of a waterproof layer, a waterproof layer is arranged on the formed one-side overhanging cover plate, so as to improve the overall waterproof effect.
