Description
Technical Field
The invention relates to the technical field of flat roofs and assembled buildings, in particular to an energy-saving assembled structure flat roof and a construction method thereof.
Background
The information disclosed in the background of the invention is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an admission or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
Flat roofs do not have a closed top layer and therefore have a poorer insulating ability than sloping roofs.
The top layer is mainly in the structure of sloping roof, it is located on the roof and forms a closed air space with the roof. The air interlayer can effectively prevent heat transfer, so that the heat insulation performance of the roof is improved.
At high temperatures in summer, the heat of solar radiation will first heat the outer layer of the roof and then be transferred to the inner layer by means of heat conduction. In this process, if the roof has a topped layer, the air in the air space will act as a heat shield, reducing the transfer of heat to the inner layer and thus lowering the indoor temperature.
The flat roof is not covered with the top layer, so that the whole roof can be directly heated by the heat of solar radiation, and the indoor temperature is increased. In addition, the flat roof has a small thermal resistance, that is, poor heat insulation, which is one of the causes of the increase in indoor temperature.
Therefore, in order to improve the heat insulation performance of the flat roof, measures such as laying heat insulation materials on the roof, arranging a layer for empty space, installing a black sun screen, etc. are generally taken to reduce the influence of solar radiation on indoor temperature and improve the comfort of living.
However, laying the heat insulating material easily causes the roofing bulge, and setting up the layer of empty and installing black sun screen all can need construction many times, increases the cost, moreover, still has the potential safety hazard. In addition, periodic maintenance is required, and the aesthetics of the building construction is affected.
