Description

A waterproof drainage system of assembled roofing for modular building

Technical Field

The utility model relates to a waterproof drainage system for assembled roofing of module building belongs to the building field.

Background

With the development and maturity of social economy, the national attention on environmental protection, production transformation of building industry and development and application of novel building materials are met with very good market opportunities and vigorous development opportunities. The modular building is a result form of building industrialization industry, and a development direction for advocating green environmental protection and energy conservation becomes a hot topic and a sunward industry of the building market at the present stage. Since the market for modular buildings began later, development was rapid but the related art was still immature. The existing modular building mainly comprises a container type modular house, a wood structure type modular house and a steel framework type modular house. And designing the single box body module in a factory, and then assembling, splicing and stacking on site. The existing roof waterproof traditional method of the three module buildings is that each module single body is provided with an independent roof drainage system, a drainage roof is formed by welding traditional roof box boards or combining a framework and a waterproof board, then drainage grooves are reserved around the single body box, and drainage pipes reserved in box body columns are drained from the drainage grooves to the outside, so that the drainage measure has no great problem for the single module body.

When several module box bodies are spliced and combined, the splicing treatment among the module bodies cannot be carried out with a targeted independent treatment measure. One of the current methods is to install rubber strips between boxes and then glue the rubber strips, and this method is very easy to cause water leakage due to aging of rubber and rubber strips and the reason that the construction operation is easy to miss and leak, and also can cause serious water leakage due to glue damage and failure caused by displacement, deformation and vibration between the module boxes. The water leakage problem cannot be completely solved even if the repair is performed again. In another common method, after the module box is assembled, an integral roof is installed on the module building for water prevention, and the steel skeleton is usually erected and then the color steel plate is laid. Although the waterproof method can solve the water leakage problem caused by the assembly of the box body, the existing problems are also obvious: firstly, the overall cost is increased, and the construction timeliness and economic economy of the module building are greatly reduced; secondly, the whole roof needs to be heightened, and a parapet is additionally arranged, so that the original design and the shape of the building are greatly damaged and influenced; thirdly, the whole roof is of an integral design, the module building is of a separated design, and when displacement and deformation are generated among the modules or under the action of an earthquake, the modules are easy to damage, so that the waterproof failure is caused.
