Description

High-rise building house balcony protection device

Technical Field

The utility model belongs to the technical field of the architectural design technique and specifically relates to a high-rise building house balcony protector is related to.

Background

With the rapid development of society, various civil high-rise buildings are more and more. High-rise civil buildings generally refer to residential buildings with 10 floors and more than 10 floors, or buildings with height greater than 28m and other high-rise civil buildings with height greater than 24 m. For the use function, there are a residential building, an apartment building, an office building, and the like. The balcony guard bar of the existing residential building is generally an external edge protection facility arranged on a balcony, is generally formed by welding or assembling a glass protection plate and a metal alloy pipe, mainly plays an important role in safety protection of people and articles living in a high-rise building and plays an important role in daily use of the high-rise building. However, the conventional protective devices such as guard rails cannot meet the requirements of various building types and different application scenarios due to single structure and single function.

For example, in the prior art, chinese utility model patent document CN213539529U discloses a safety protection balcony fence, which includes a first vertical support rod, a first protection plate is fixedly connected to one side of the first vertical support rod, and a second vertical support rod is fixedly connected to one end of the first protection plate far away from the first vertical support rod. This safety protection balcony rail, it is good to use the security, can avoid children to cross the rail when playing to be difficult for dropping during the sunning. However, it is mainly suitable for living balconies and protection of ordinary single-layer, rectilinear balconies, and not very suitable for other balcony types. This kind of rail device protects the balcony through setting up the guard plate, but it is in the in-service use process because there is the clearance usually between the guard rail, and pets such as the cat dog that raises at the resident family fall from the clearance of guard rail very easily, brings very big potential safety hazard for the bottom resident, and children also can be easily with the head card in the guard rail when playing simultaneously, cause the injury for children easily.

The existing residential balconies of high-rise buildings are classified from the aspect of functions, and generally, 1-2 living balconies and 1-2 service balconies are arranged to meet different requirements of people. The life balcony generally refers to the balcony that plants flowers and plants on it, puts some leisure equipment, has functions such as vwatching and leisure, links to each other with sitting room or bedroom usually, supplies people to have a rest and leisure amusement, and the area is generally great, and the protector of this kind of balcony not only requires practicality, still needs beautifully. The service balcony has functions of washing clothes, storing and the like, is connected with a kitchen or a dining room, and is used as a cooking operation room by a small house type with a small area, so that an oil smoke area and an oil smoke-free area are distinguished, and an original narrow kitchen space is not crowded. The area of the utility model is much smaller than that of the living balcony, and the functions are much smaller.

The existing residential balconies of high-rise buildings are classified from the aspects of building appearance and structure, and the balconies can be divided into the following three types: 1. corner formula balcony, corner arcuation balcony are located the special part of building body, and this kind of balcony form has been used more and more in the design to present building dish. Mainly for the needs of building facade design, what's more, be that the vision is wide brings a brand-new impression to people. In order to make a house with lighting on all sides, developers have balconies on both the east and south sides of the house, and then connect the channels of the two balconies together, which is called a corner balcony. 2. The raised balcony has the advantages that the floor of the balcony is higher than the floor of the hall connected with the balcony, the feeling of two or three steps staggered is formed, the space change has rich layering, and the balcony is popular with young people of fashion and literature. 3. The double-layer balcony is divided into an inner balcony and an outer balcony, the outer balcony is provided with a fence terrace and the light wind with a brushing surface can be enjoyed; the inner balcony is also called a glass sunshine room and is used for shielding wind and sand indoors.

In conclusion, the existing protective devices such as the balcony fence of the high-rise building cannot meet the requirements of various balcony functions and structures, cannot adjust the size and the structure, and cannot better meet the individual requirements in various application scenes such as attractiveness, decoration and scale change.
