[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] Example 1, please refer to Figure 1 The present invention provides a technical solution: a composite waterproof closing strip based on non-curing rubber asphalt, comprising a parapet 1, a house roof 2, a waterproof strip 3, a waterproof coating 4, and a waterproof roll 5. The waterproof coating is coated on one side wall of the waterproof strip, and the waterproof strip is fixed to the parapet by a fixing screw 6. The side of the waterproof strip coated with the waterproof coating contacts the parapet, and the waterproof roll is bonded to the left surface of the parapet and the upper surface of the house roof. The upper end of the waterproof roll is pressed onto the left side wall of the parapet by the waterproof strip, and a reinforcing glue 7 is applied between the waterproof strip and the parapet. The upper end of the waterproof roll can be sealed by utilizing the viscosity of the waterproof coating and the cold adhesion effect of the reinforcing glue. A plurality of fixing screws are nailed on the waterproof strip at a fixed interval so that the waterproof strip will not loosen naturally and fall off. Holes will be generated when the fixing screws pass through the waterproof strip, and the waterproof coating will seal the holes, thereby preventing water seepage at the holes.

[0015] Specifically, the waterproof pressure strip is a galvanized sheet waterproof pressure strip or an aluminum alloy waterproof pressure strip. The galvanized sheet waterproof pressure strip or the aluminum alloy waterproof pressure strip has the advantages of being rust-proof and durable, and is suitable for use in the device.

[0016] Specifically, the waterproof coating is a non-curing rubber asphalt coating, and the thickness of the waterproof coating is 1.5mm-2.5mm. The non-curing rubber asphalt coating is a new type of waterproof material that can maintain a viscous paste for a long time in the application state and has creep properties. The non-curing rubber asphalt coating can close the capillaries, thereby making the device more waterproof.

[0017] Specifically, the waterproofing membrane is an SBS modified asphalt waterproofing membrane, which has a good waterproofing effect.

[0018] Example 2, please refer to Figure 2 The difference between this embodiment and embodiment 1 is that: the lower end of the waterproof strip is installed with an insulation laminate 8 and a rubber insulation layer 9 by screws, the rubber insulation layer is bonded to the waterproof coiled material, and a foam insulation block 10 is filled between the rubber insulation layer and the insulation laminate. In some northern regions, the winter temperature is too low, possibly below minus 25 degrees Celsius. Under such low temperature conditions, the waterproof coiled material may be damaged, so the combined effect of the rubber insulation layer and the foam insulation block can slow down the temperature change and enhance its low temperature resistance.

[0019] Working principle: The present invention uses multiple fixing screws to nail the waterproof strip at a fixed interval to prevent the waterproof strip from loosening naturally and falling off. The fixing screws will produce holes when passing through the waterproof strip, and the waterproof coating will seal the holes to prevent water seepage in the holes. The combined action of the rubber insulation layer and the foam insulation block can slow down temperature changes and enhance its low-temperature resistance.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
