Problems solved by technology

There are many reasons for roof leaks in old houses. The common ones are the age of the house, the aging of the waterproof membrane caused by disrepair, the seepage of the insulation layer, and the cracking of the roof waterproof layer; and a large part of the old houses do not have insulation. There are old houses with overhead insulation layer, the insulation layer is also seriously damaged due to aging, and cannot play the role of thermal insulation in summer, which affects the normal life of residents on the top floor
The existing old roof renovation scheme adopts the traditional inverted roof scheme (first paste the coiled material, then put the extruded board, and finally make the fine stone concrete protective layer), which has the following disadvantages: the construction process is relatively complicated, the cost is high, The waterproof and thermal insulation performance is poor, and the roof is prone to cracking and water seepage. It is neither economical nor practical to apply in engineering practice.
The construction method in this patent requires the use of large-scale pumping equipment, and the steps of configuring foam concrete are cumbersome. For the reconstruction project of the roof of the old house with a small area, its economic efficiency is poor, which is not conducive to popularization and application

Abstract

The invention belongs to the field of engineering building construction, and particularly relates to a waterproof and energy-saving integrated system for old roof reconstruction. A construction process of the waterproof and energy-saving integrated system includes the following steps that an old asphalt layer is removed to enable a base surface to be level, dry and dust-free, and PTB mortar is scraped or brushed on the base surface to modify an interface of a base layer; a bearing waterproof roll / polyethylene polypropylene waterproof roll / polyethylene polyester waterproof roll is paved on a roof gutter, an extruded polystyrene foam (XPS) board is paved, and holes are filled with cement mortar; PTB net paste is brushed, and the bearing waterproof roll / polyethylene polypropylene waterproof roll / polyethylene polyester waterproof roll is paved; and one day later, a 3-5mm thick polymer cement waterproof mortar anti-cracking layer is applied on the surface of the waterproof roll, and a PTB curing agent is sprayed evenly when the surface is dry. The construction period is short, the roof load is small, the construction efficiency can be greatly improved, the waterproof and energy-saving effect is good, energy-saving and waterproof reconstruction can be carried out on an old roof efficiently, and the service life is prolonged, so that the living environment is improved.

Description

technical field [0001] The patent of the present invention relates to the technical field of building construction, in particular to an integrated waterproof and energy-saving system for old roof renovation. Background technique [0002] With the rapid development of my country's economic level, the scale of urbanization continues to expand, a large number of new houses are continuously built, and the number of old houses is also increasing. The problem of roof leakage of old houses has always been a difficult and miscellaneous disease in the field of construction. There are many reasons for roof leaks in old houses. The common ones are the age of the house, the aging of the waterproof membrane caused by disrepair, the seepage of the insulation layer, and the cracking of the roof waterproof layer; and a large part of the old houses do not have insulation. There are old houses with overhead insulation layer, the insulation layer is also seriously damaged due to aging, and can...
