Balcony protective frame convenient to contract

Abstract

The invention discloses a balcony protective frame convenient to contract, and relates to the technical field of building engineering. The balcony protective frame convenient to contract comprises twoprotective frame bodies, wherein each protective frame body is of an L-shaped structure; side protective plates are installed on one sides, opposite to each other, of the two protective frame bodies;front baffle plates parallel to vertical parts of the two protective frame bodies are installed at the ends of horizontal parts of the two protective frame bodies; and expansion bolts are fixed at the four corners of the vertical parts of the two protective frame bodies. According to the balcony protective frame convenient to contract, through the arrangement of first plate bodies, second plate bodies, inserting rods, inserting slots and inserting plates, the side protective plates form a telescopic structure; and through the arrangement of a first protective plate, a second protective plate,clamping holes, clamping blocks, a connecting plate and return springs, outer protective plates form a telescopic structure, so that the protective frame is adjusted according to the wall structure of a balcony, the applicability of the protective frame is effectively improved, and the application range of the protective frame is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a balcony protective frame which is easy to shrink. Background technique [0002] With the continuous development of society, people's living standards are rapidly improving, and at the same time of development, especially the continuous acceleration of urbanization, the population is constantly concentrated in specific areas, especially in large and medium-sized cities with better infrastructure. In places where the population is increasingly concentrated, in order to provide housing for people and save land to the greatest extent, high-rise buildings have become the first choice for housing and commercial real estate, while prefabricated buildings are built quickly and are less restricted by climatic conditions, saving labor and can Improving the quality of the building, and the production cost is low, and it has been rapidly promoted all over the w...

Problems solved by technology

[0003] In the Chinese patent with the patent number CN201721090474.5, a stereotyped outer protective frame system for prefabricated building construction is mentioned. The structure is equipped with stainless steel back bolts, and plastic Spacers reduce the damage to the decorative surface of the wall when the protective frame is collided or squeezed. At the same time, the device is equipped with chute and slider so that the height of the angle steel frame can be adjusted at any time, thereby adjusting the height of the protective frame , in order to meet different needs. At the same time, the device is installed with cross connectors and wires, so that the horizontal bar, the vertical bar and the steel mesh can be firmly fixed to prevent damage and cause material fall and cause casualties. At the same time, the steel mesh inside There is an insulation layer and a waterproof layer, which can not only keep heat and prevent leakage, but also avoid the danger caused by small tools slipping from the gaps in the steel mesh. However, the protective frame cannot be adjusted according to the structural requirements of the balcony wall. The structure of different protective frames is poor in applicability, resulting in limited scope of application, and it is not convenient for the shrinkage of the protective frame, resulting in a large space occupied by the protective frame, which is not convenient for the storage or handling of the protective frame. In addition, the protection of the protective frame The performance is poor, and the balcony wall cannot be protected from wind and rain, causing the balcony wall to be easily corroded and aging, which affects the service life of the balcony
