Modular prefabricated concrete circular arc chamfering waterproof system for waterproof paving of roofing coils and construction method of modular prefabricated concrete circular arc chamfering waterproof system

Abstract

The invention discloses a modular prefabricated concrete circular arc chamfering waterproof system for waterproof paving of roofing coils. The modular prefabricated concrete circular arc chamfering waterproof system is applied to a corner at a connection position of a roofing parapet and a roofing board. The waterproof system includes a plastering layer arranged on the roofing parapet and a screed-coat, an insulation layer, an isolating layer, a protective layer and a waterproof layer, wherein the screed-coat, the insulation layer, the isolating layer, the protective layer and the waterproof layer are arranged on the construction roofing board; the waterproof system further includes modular prefabricated concrete circular arc chamfering which is paved at the corner at the connection position of the roofing parapet and the roofing board; the prefabricated concrete circular arc chamfering is internally provided with anti-cracking steel bars; a waterproof flashing closure is arranged at the splicing head position of the prefabricated concrete circular arc chamfering and the plastering layer of the parapet; and a gap is reserved at the splicing head position between the prefabricated concrete circular arc chamfering, a gap is further reserved at the splicing head position of the prefabricated concrete circular arc chamfering and the screed-coat, and the gaps are filled with waterproof ointment. The problems of large randomness, difficult shape control and poor molding quality when the circular arc chamfering is made by adopting cement mortar by plasterers are solved.

Description

technical field [0001] The invention relates to a roof waterproofing system, in particular to a modular prefabricated concrete circular-arc chamfered waterproofing system used for waterproofing of roofing membranes and a construction method thereof. Background technique [0002] In modern buildings, membrane waterproofing is widely used due to its remarkable waterproofing effect and convenient construction. With the advancement of science and technology, the performance of the membrane waterproof material has been further improved, and its durability, high temperature resistance, puncture resistance and corrosion resistance have been improved, making the membrane waterproofing more widely used in building waterproofing. [0003] Due to the rapid change of waterproof performance of membrane, it plays an important role in building roof waterproofing and is widely used. Therefore, more and more attention has been paid to the construction quality and appearance effect of membra...
