The waterproof material of the terrace should be coiled material, which can effectively avoid the damage of ultraviolet rays to the waterproof layer and the damage of temperature difference to the waterproof layer. It is best to waterproof the terrace with coiled material twice, and don't destroy the waterproof layer when decorating the surface.
Second, the bearing capacity.
To consider the bearing capacity of the terrace, the bearing capacity of the whole terrace should be calculated according to the drawings of the original building (if there is no original data, it can be calculated according to 550 kilograms per square meter), and the bearing capacity of the unit area should also be considered, otherwise the accident of bearing more than the load will cause harm to the whole building and people.
Third, the drainage system
Terrace drainage should adopt straight slope drainage, and trench drainage is not recommended. The main problem of trench drainage is that the waterproof layer is easily damaged by temperature factors, resulting in water leakage. The size of the drainage outlet should be determined according to the size of the terrace area (one square meter diameter is calculated according to one kilogram flow), so as to avoid blockage due to the small drainage outlet. In summer, when the rain is too heavy, the whole terrace becomes a pond, and the rain is reinjected into the room.
Fourth, the balcony is flooded.
Sheung Shui on the terrace means that tap water is left on the terrace. It is convenient to clean the terrace when living and using. This method is not recommended in principle. The main reason is that water resources are wasted. You can prepare a big bucket on the terrace to collect rainwater. The terrace is dirty, so you can wash it with the water in the bucket. However, if running water is installed, we should consider the problem of antifreeze in winter. Install tee joints, valves and faucets indoors. Before winter comes, drain the water from the water pipes leading to the outdoor terrace to prevent the water pipes, especially the outdoor faucets, from freezing and cracking.
Fifth, the circuit.
The circuit of terrace mainly refers to the circuit of installing dew lamp. There are two issues to consider. One is that the problem of pipeline should consider the phenomenon of water accumulation in the pipeline caused by condensation caused by "cold bridge", which is easy to cause short circuit after water accumulation. The other is that the waterproof and antifreeze performance of lamps is better.
