Embodiment 1

[0055] This embodiment provides a cantilever-type balcony reinforcement method for sound insulation reconstruction. The original fence 3 is retained, and the original fence 3 is added along the top of the original fence 3 and the outer sides of the original fence 3, the original cantilever 4, and the original sealing beam 5. 10 sound-insulating window caps, 7 additional layers of fence panels, 8 additional layers of cantilever beams, and 9 additional layers of sealing beams, 10 sound-insulating window caps, 7 additional layers of fence panels, 8 additional layers of cantilever beams, and additional layers of sealing beams 9 Through the reliable connection of steel bars and steel bars to the original components, it is formed by integral pouring, which improves the overall rigidity, bearing capacity and sound insulation performance of the balcony slab.

[0056] Further, the original fence 3 is retained, and mechanically drilled after accurate positioning, and U-shaped stirrups g ...

Embodiment 2

[0074] This embodiment provides a cantilever-type balcony reinforcement structure for sound insulation reconstruction, which includes a sound-insulating window cap plate 10 , an additional layer of railings 7 , an additional layer of cantilever beams 8 and an additional layer of sealing beams 9 . Wherein, the sound-insulating window cap plate 10 is designed according to the size of the sound-insulating window member 14; the fence adding layer 7 is arranged on the outside of the original fence 3, and is firmly combined with the original fence 3, so that the total fence meets the requirements of sound insulation. Requirements; the cantilever beam plus layer 8 is laid with two layers of horizontal steel bars, and is reliably connected with the original cantilever beam 4, the ring beam 6, and the wall body 13; the described sealing beam plus layer 9 is designed according to the upper load, and the The plate plus layer 7 and the cantilever plus layer 8 are reliably connected.

Abstract

The invention discloses an outrigger-type balcony reinforcing method and structure for sound insulation reformation. The method includes: with original breast boards retained, chiseling surfaces of the original breast boards, original outriggers and original seal beams; adding sound-insulating window bearing sheets, breast board added layers, outrigger added layers and seal beam added layers to the tops of the original breast boards, outer sides of the original breast boards, outer sides of the original outriggers and outer sides of the original seal beams, respectively, by integral casting; connecting the breast board added layers to the original breast boards through U-shaped stirrups and to a wall by bar embedding; connecting the outrigger added layers to the original outrigger beams, ring beam and wall by bar embedding; connecting the seal beam added layers to the original seal beams by bar embedding and to the outrigger added layers by bar bending and anchoring; and connecting the sound-insulating window bearing sheets to the original breast boards by bar embedding. The original breast boards are made effective use, bearing capacity and stability of a balcony are greatly improved, sound insulation of balcony breast boards is greatly improved, and the method and the structure are applicable to existing building balcony reinforcement projects.

Description

technical field [0001] The invention relates to a reinforcement method and a reinforcement structure for a beam-hanging balcony for sound insulation reconstruction of existing residential buildings, and belongs to the technical field of civil engineering reinforcement. Background technique [0002] The sound insulation renovation of balconies is an important part of the sound insulation renovation of existing residential buildings, including the installation of balcony sound insulation windows and the improvement of sound insulation performance of balcony railings. Among them, the cantilevered balcony is one of the most widely used types of balconies. Due to various reasons such as congenital design reasons, construction quality, and improper use in the later period, it is easy to cause damage to the cantilever beams, balcony slab cracks, and deflection deformation at the end of the slab. The phenomenon of exposed bars or broken steel bars seriously reduces the bearing capac...
