Description

Technical Field

[0001] The utility model relates to the technical field of building design, in particular to a nearly zero-energy consumption building roof. Background Art

[0002] Energy conservation and emission reduction are the major trends in the development of the world today. Low-energy buildings create a harmonious environment between man and nature, guide the progress of building energy-saving technology, and the corresponding technology will also have a wide range of application needs.

[0003] There are many devices on the building roof, such as air source heat pump equipment, air conditioning outdoor equipment, etc. The equipment foundation is in direct contact with the structural plate, interrupting the insulation. A thermal bridge is formed at this location, and the insulation layer cannot be continuous. When the equipment foundation area is large, it has a greater impact on the overall energy-saving effect of the building and increases the building energy consumption. In addition, the waterproofing at this location is also difficult to handle. Once the waterproofing is damaged, it is difficult to find the exact location.

[0004] However, it still has the following disadvantages in actual use:

[0005] The existing near-zero buildings, passive buildings, and ultra-low energy consumption buildings are the development direction of buildings, and are also the inevitable development trend of future buildings. With the rapid development of such buildings, their applications will become more and more extensive. The traditional roof equipment foundation approach has little consideration for the treatment measures of insulation and blocking thermal bridges. The common approach of waterproofing + mortar is generally adopted, which cannot guarantee the continuity of the roof insulation layer; at the same time, the problem of equipment foundation waterproofing is also a location where hidden dangers are prone to occur in buildings. The reserved embedded parts of the equipment foundation also have a certain impact on the insulation and waterproofing structure. After the holes are punched in the roof of the building, there are certain hidden dangers in insulation and waterproofing, which have high requirements for construction and testing, and the leakage points are not easy to find. In the past, waterproofing could be added to prevent leakage in the rain, but there was a gap between the screws and the holes, which required high waterproofing technology. If the waterproofing is too thick, it will affect the installation. If it is thin, it will not work, and this post-remedy measure is often not very reliable.

[0006] Therefore, a new near-zero energy consumption building roof is proposed to solve the above problems. Utility Model Content

The common approach of waterproofing + mortar is generally adopted, which cannot guarantee the continuity of the roof insulation layer; at the same time, the equipment foundation waterproofing problem is also a location where hidden dangers are prone to occur in the building. The equipment foundation reserves embedded parts, which also have a certain impact on the insulation and waterproofing structure. After the building roof is punched, there are certain hidden dangers in insulation and waterproofing, which have high requirements for construction and testing, and the leaking point is not easy to find. In the past, waterproofing can be added to prevent water leakage in rain, but there is a gap between the screws and the holes, which requires high waterproofing technology. If the waterproofing is too thick, it will affect the installation. If it is thin, it will not work. This kind of post-remedy measure is often not very reliable.

Therefore, the thermal bridge treatment measures and waterproofing measures of the equipment foundation on the roof were studied.

[0036] After the roof structure layer 9 and the concrete equipment foundation 8 are set in position, the equipment foundation can be prefabricated or cast-in-place.
