1. Reinforced concrete wall structure that forms a wall by inserting reinforcing bars and injecting concrete; A vibration-canceling embedded beam characterized by including an embedded beam configured to traverse the long span direction to prevent heavy impact sound without increasing the thickness of the inter-story slab in the above reinforced concrete wall structure, and configured to be combined with the reinforcing bars of the wall.

Description

Vibration-absorbing landfill The present invention relates to a technology for a vibration-canceling embedded beam to prevent gravity impact sound, which is inter-floor noise. Luxury villas generally adopt a frame structure for the basement and a reinforced concrete wall structure for the residential floors above ground. As a result, the increased span of bedrooms and living rooms can lead to vulnerability to heavy impact noise. The following attempts were made to resolve the problems arising from this. The background technology is Korean Intellectual Property Office Patent No. 10-1433663 (August 29, 2014). Accordingly, the explanation is as follows. FIGS. 10a to 10c are perspective views showing a first example of an inter-floor vibration noise absorption device according to the background technology and an installed state. The sound absorption device for inter-floor vibration noise in a multi-story building according to the background invention is equipped with a sound absorption tube (10). This sound absorption tube (10) performs the role of removing noise, such as floor impact sound, intended in the background invention. These sound-absorbing tubes (10) can be made of a lying cylinder or a lying triangular column as first examples. In the background invention, multiple sound-absorbing tubes (10) are stacked toward the bottom surface of the floor slab, and in particular, the sound-absorbing tube (10) located at the bottom layer is fixed to a support plate (20). Accordingly, a certain space must be formed between the base plate (20) and the bottom surface of the floor slab, and sound-absorbing tubes (10) according to the background invention are installed in this certain space. In the sound-absorbing tube (100) of the background invention, which is composed of a lying cylinder or a lying triangular column, a plurality of sound-absorbing holes (12) are formed through the surface. This sound-absorbing hole (12) serves to guide noise traveling downward into the sound-absorbing tube (10) and to cancel out the noise inside. In the background invention, each of the above sound-absorbing tubes (10) is stacked in an intersecting manner. The sound-absorbing tubes (10) made of a lying triangular prism or a lying cylinder have both sides in the longitudinal direction, that is, both bottom surfaces, sealed, and in particular, the bottom surface of the sound-absorbing tube (10) made of a triangular prism is also a closed structure. To form this fixed space, a hanger (30) is installed on the bottom surface of the base plate (200) and the floor slab. In the background invention, the hanger (30) is separated, and a rubber ring (40) is installed between them. The rubber ring (40) is made of an elastic material such as rubber and urethane, and serves to cancel out vibrations transmitted between the hangers (30). In particular, the rubber ring (40) has hook holes (41) formed on both sides for hooking the hanger (30), and a plurality of holes (42) are formed between the hook holes (41), and these holes (42) can be formed in various shapes such as circular or polygonal. Vibrations can be further dampened by these holes (42). In addition, a rubber plate (50) is installed between the base plates (20) to connect them. The rubber plate (50) is made of rubber and urethane and simultaneously performs the role of canceling out shaking or transmitted vibrations of the base plate (20). However, this configuration has an adverse effect on the strength of the slab, which naturally leads to a significant increase in the thickness of the slab, thereby significantly increasing construction costs in row houses with height restrictions. The present invention proposes an invention that has the same effect as substantially increasing the thickness of a slab without increasing the thickness of the slab.
