Description

Technical Field

[0001] The utility model relates to the technical field of engineering prefabrication, in particular to a superimposed prefabricated balcony with a flower bed. Background Art

[0002] With the rapid development of the construction industry, more and more buildings are prefabricated. The factory implements standardized production components to improve work efficiency and reduce energy consumption. As an important part of prefabricated buildings, prefabricated balconies have been studied by many engineers. Traditional prefabricated balconies are generally lighter because they have to consider their connection with the main structure. In the existing technology, prefabricated balconies do not have decorations or flower beds for growing flowers and plants. Flowers and plants can only be grown in flower pots. In order to better adapt to the current construction market demand, if you want to add flower beds as decoration, the load of the prefabricated balcony will be further increased. The existing technology has become increasingly unable to meet the growing needs of life, and it needs to be achieved through structural optimization.

[0003] Traditional plate-type cantilevered prefabricated balconies do not need to deal with the problem of beam node connection. Cantilevered ribs are laid in the superimposed layer of the floor slab and can be used for prefabricated structures. However, the plate-type cantilevered balconies are subject to large deformation under stress and low bearing capacity, which makes it difficult to meet the bearing capacity requirements. They can only be used for relatively light and small balconies. Traditional beam-type cantilevered prefabricated balconies are difficult to apply to fully prefabricated structures due to the difficulty in handling the connection of the beam end nodes. They are generally more common in the main cast-in-place structure. In addition, there are problems such as the beam reinforcement diameter is too large and the reinforcement is too dense. When sleeve connections are used, the sleeves cannot be placed. Utility Model Content

[0004] The purpose of the utility model is to provide a prefabricated overlapping balcony with a flower bed, so as to solve the problem that the prefabricated balconies in the prior art are not suitable for decoration or can only be used to grow flowers and plants in flower pots, and at the same time solve the problem of low bearing capacity caused by unreasonable structural aspects of the prefabricated balconies.
