Description

TECHNICAL FIELD

[0001] The utility model relates to building structure technical field especially relates to a reinforced building balcony cantilever beam structure. BACKGROUND

[0002] As an important expansion part of building space, the stability and bearing capacity of the structure of balcony are directly related to the safety and use function of building, and the cantilever beam of balcony as the key structural component of supporting balcony bears the weight of balcony itself, crowd activity and possible other loads, so the performance requirement thereof is extremely high.

[0003] The traditional cantilever beam structure of balcony usually adopts relatively simple reinforced concrete structure form, in this structure, the arrangement mode of steel reinforcement framework is relatively conventional, and the spacing of stirrup is often uniformly arranged, so it is impossible to strengthen the key stress position of cantilever beam, which makes the end and other weak areas of cantilever beam prone to cracking, deformation and other problems when bearing large load for a long time, resulting in the gradual decline of bearing capacity, which seriously affects the safety and service life of balcony.

[0004] Meanwhile, the connection mode between the traditional cantilever beam of balcony and shear wall and floor slab is relatively single, and is mostly dependent on the combination of simple steel anchoring and concrete pouring, and the stability of connection is insufficient when facing natural disasters such as earthquake, gale and large dynamic load, and the connection part is prone to looseness, separation and other situations, thereby causing the overall instability of balcony structure.

[0005] In terms of improving bearing capacity, the traditional structure rarely adopts prestressed technology, and even if it is applied, there are problems such as great construction difficulty and inconvenient operation. For example, in the process of concrete pouring, the pre-stressed tendon is difficult to set and fix, and the post-prestressed tension and grouting operation is complex, which affects the construction efficiency and quality, and the traditional mortar sealing anchor method is not only complicated in construction, but also difficult to guarantee the sealing anchor effect, and is prone to problems such as corrosion of the end of pre-stressed tendon, which further weakens the structure performance.

[0006] With the development of building industry, people put forward higher requirements on the safety, durability and functionality of building structure, and the existing cantilever beam structure of balcony is difficult to meet these needs, and a new type of reinforced building balcony cantilever beam structure is urgently needed to improve the bearing capacity, enhance the connection stability, and optimize the construction process and post-maintenance performance.
