A green roof device

Abstract

The invention belongs to the field of building energy conservation, and particularly relates to a greening phase-change box bridge. The greening phase-change box bridge is used for connecting greeningphase-change boxes and comprises a joint and connectors movably arranged inside the joint; the joint comprises four connecting ports; the connecting ports communicate with one another in the warp andweft directions of the joint; the connectors are inserted in the connecting ports and are made of plastic; cavities are formed inside the connectors; and IXPE foam is arranged inside the cavities. Each greening phase-change box comprises a flower disk, a tray and an energy storage disk which are assembled up and down; and phase-change materials are lid inside the flower disk, the tray and the energy storage disk. According to the bridge, the phase-change materials are lid inside the flower disks, the trays and the energy storage disks, and when the outside temperature changes, the phase-change materials absorb or release heat to play a role in heat insulation for a roof; and the multiple greening phase-change boxes are assembled and combined according to the roof design, so that the lightplanting roof heat insulation system can be formed.

Description

technical field [0001] The invention belongs to the field of building energy saving, in particular to a roof greening device. Background technique [0002] Due to the rapid development of urban industry and transportation, the discharge of all kinds of dust and waste gas, the further aggravation of environmental pollution, the relative increase of building density, and the relative scarcity of green spaces have affected the physical and mental health of the people. Real estate development has intensified the reduction of urban green space, increased the heat island effect and air pollution, increasing the greening rate and beautifying the environment are people's expectations. Roof greening plays an important role in haze control, oxygen release, dust removal and noise reduction, especially in the country In the case of strongly recommending green buildings in sponge cities, most cities across the country have stipulated that the roof greening rate should not be less than on...

Problems solved by technology

[0003] At present, in China, people have made more efforts to solve the problem of roof greening. Some people use concrete and extruded boards to make "sandwich" templates, some people use steel frames to make flower stands, and some people use plastics. Planting trays, etc. Although these methods have solved the problem of roof greening to varying degrees, but at the same time, there are problems that the system cannot meet the thermal performance requirements of the roof, or the process is complicated, or the cost is high, or the versatility is not high, and the flexibility is not high. strong, or it is not convenient for later maintenance, or the fire resistance performance does not meet the requirements, etc.
