Prefabricated assembly-type balcony

Abstract

The invention discloses a prefabricated assembly-type balcony which comprises a solar panel 1, a vertical baffle 2, a horizontal balcony plate 3 and a rainwater collecting box 8. The vertical baffle 2and the horizontal balcony plate 3 are perpendicularly arranged and prefabricated into a whole through a steel bar structure, and the inner side of the horizontal balcony plate 3 is fixed to a building main body. The outer side of the horizontal balcony plate 3 is sequentially provided with a balcony rabbet 12, a first convex groove 13 and a second convex groove 15. One end of the solar panel 1 is fixed to the vertical baffle 2, and the other end of the solar panel 1 is fixed into the first convex groove 13 through a hinging part 21 reserved at the bottom of the solar panel 1. The middle of the solar panel 1 is connected with an automatic telescopic device 24 which is arranged in a reserved space of the second convex groove 15 and used for controlling the angle of the solar panel 1. The vertical baffle 2, the horizontal balcony plate 3 and the solar panel 1 are combined, thus the heat preservation and insulation effects are improved, assembly-type integration development of the building industry can be further improved, the construction efficiency is improved, and building energy consumption is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an energy-saving and environment-friendly prefabricated balcony. Background technique [0002] my country's existing total construction area is more than 40 billion square meters, and it is estimated that by 2020, an additional construction area of ​​about 300 square meters will be added. Building components occupy a large amount of land, and the energy directly consumed in the process of construction and use accounts for 30% of the total energy consumption of the whole society; 30% of the country's steel consumption, cement accounted for 25%. my country's building energy consumption is high, and reducing building energy consumption is an important way to build a conservation-oriented society. Therefore, comprehensive energy conservation in the construction industry is imperative. The energy conservation of buildings should first be valued by designers. ...

Problems solved by technology

[0004] Chinese patent document CN206090814U discloses a "prefabricated balcony panel", which is to fix the solar photovoltaic panel on the outside of the balcony panel, pour the external insulation material between the solar photovoltaic panel and the balcony panel, or directly use the solar photovoltaic panel Instead of external heat preservation, the solar panel plays a blocking role in the heat transfer from the outdoor to the indoor, reducing the heat transfer to the indoor, but there are still the following problems: (1) The function of the solar photovoltaic panel is only to irradiate the outer surface of the building The solar energy is converted into electric energy, which has the effect of heat insulation, but cannot play the role of heat preservation, and cannot directly replace the external insulation structure of the balcony slab. Insulation treatment, the insulation effect is not ideal; (2) The solar photovoltaic panel is fixed on the outside of the balcony panel vertical to the ground, and can only use the solar energy irradiated on the solar photovoltaic panel. The local sun's illumination angle changes, which cannot make full use of solar energy and improve the conversion rate of light energy. Moreover, there is no thermal insulation device on the horizontal surface of the balcony, which is not practical and has limitations.

(3) The service life of the main body of the building is greater than the service life of the solar photovoltaic panels, which has the problem of how to replace the solar photovoltaic panels if they are partially or overall damaged. It is inconvenient to disassemble, and it is easy to damage the structure of the balcony plate, which increases the cost
