What is the difference between indoor and outdoor terraces
Floors are the most common thing in our daily lives. Nowadays, people like to use them to decorate the ground. Floors are not only beautiful, but their low prices can also save us a lot of money. Floors are also durable and can withstand the test of time. Generally, in civil engineering, the flooring can be divided into two types: indoor flooring and outdoor flooring. Outdoor flooring generally refers to the construction layer of the original foundation after leveling (excavation or filling). The construction layer is divided into original soil layer, base layer, intermediate layer, surface layer, etc. The outdoor design floor elevation is the outdoor elevation of the building after delivery, which is determined by the designer based on the original terrain elevation and the functional needs of the building. It is generally represented by a solid triangle and a number.
The construction process of indoor flooring is generally similar to that of outdoor flooring, but due to the influence of usage functions, there are certain differences in strength, thickness, and materials between indoor flooring and outdoor flooring, which is why they are separately referred to as outdoor flooring and indoor flooring.
Some customers may sometimes complain about the poor performance of certain epoxy flooring, but sometimes the various problems with the flooring are not related to the quality of the flooring itself. Part of the reason may be due to environmental factors leading to improper selection and design of the flooring paint system. For example, if many indoor floors are used outdoors, their service life will be greatly reduced. There are differences in the selection of indoor and outdoor flooring.
Generally speaking, outdoor flooring needs to have good weather resistance, while some flooring products may have good wear resistance, high cleanliness requirements, or good anti-corrosion performance. However, their weather resistance is poor, and after prolonged exposure to sunlight, they may experience discoloration, peeling, and cracking, greatly shortening their service life. So when choosing outdoor flooring, it is important to pay attention to its weather resistance, and then choose different flooring products according to different needs. For example, UV resistant and weather resistant flooring has excellent weather resistance, while permeable flooring not only has good weather resistance, but also has good water permeability, and so on.
On the other hand, indoor flooring does not need to consider weather resistance, but only needs to choose suitable flooring according to different needs. If you need ground anti-corrosion, choose anti-corrosion floor paint. If you need an anti-static environment, consider epoxy anti-static flooring, etc. When choosing flooring, including floor paint, we need to choose the corresponding product according to our own needs to achieve the desired effect.
Determination of outdoor ground elevation and indoor ± 0.000 elevation
(1) Coordinate with external transportation and municipal facilities, and facilitate production and usage connections internally. Connect with the surrounding road traffic, with a reasonable slope, maintain smooth traffic, and timely divert traffic when encountering traffic problems
(2) Meet drainage and flood control requirements
1) Flood control and drainage: It should be ensured that the designed ground elevation of the site is 0.5m higher than the designed frequency flood level. Generally, there is a clear minimum site elevation and indoor soil elevation of 0.000 in urban flood control planning. When the site is temporarily connected to urban roads, the elevation at the red line of the land should be 0.20~0.40 higher than the elevation of the urban road centerline.
Coordination between design elevations: Generally, the road design elevation should be lower than the outdoor floor elevation of the building to meet the requirement of no water accumulation on the site.
2) Elevation of municipal sewage pipeline access point: The drainage slope of ground and underground pipelines meets the requirements of drainage specifications. The starting point of underground pipelines should also meet the minimum soil cover depth requirements.
(3) Consider the impact of groundwater level, earthwork volume, foundation burial depth, and building settlement.
Excavation is not suitable in areas with high groundwater levels to reduce the cost of waterproofing construction caused by dealing with groundwater levels. In areas with low groundwater levels, appropriate excavation can be considered to obtain higher endurance and reduce foundation burial depth. It is best to keep the building foundation, equipment foundation, and pipe trench above the groundwater level of 0.5 meters. Reduce the amount of earth and rock filling, excavation, and foundation engineering.
(4) Environmental landscape requirements, determination of indoor and outdoor floor design elevations, should have a forward-looking perspective that is harmonious with adjacent buildings while considering urban development and changes, and create a beautiful landscape.
(5) Determination of indoor elevation of 0.000
The height difference between indoor and outdoor levels of buildings: Generally, it should be determined based on factors such as the nature of use, population requirements, site topography, and geological conditions of various buildings, and the minimum height difference between indoor and outdoor levels should meet relevant regulatory requirements. For buildings with basements, the indoor floor elevation should generally be 0.3, 0.4, 0.6, and 1.00 higher than the outdoor floor to avoid rainwater backflow. It is necessary to consider the convenience of building use.
