Inner-riveting-type fixing fastener for architectural acoustic reconstruction

Abstract

The invention provides an inner-riveting-type fixing fastener for architectural acoustic reconstruction. The fastener comprises an inner fastening plate, a suspension connecting piece, extension limiting sheets and limiting sheet adjusting mechanisms; a connecting hole is formed in the middle of the inner fastening plate, and limiting grooves are formed in the two sides of the inner fastening plate inwards; the extension limiting sheets are slidably mounted in the limiting grooves; one end of the suspension connecting piece is cooperatively connected with the connecting hole, and the other endof the suspension connecting piece is connected with a connecting screw; each limiting sheet adjusting mechanism comprises a silicon steel sheet, a connecting wire, a power source and a limiting spring; each silicon steel sheet is mounted at the groove bottom of the corresponding limiting groove; each connecting wire spirally winds the surface of the corresponding silicon steel sheet and is connected with the corresponding power source to form a loop; the silicon steel sheets and the extension limiting sheets are connected through the limiting springs. The fastener can be mounted simply by forming a long-strip-shaped mounting hole in a mounting surface, a sound absorbing material is fixedly mounted on the basis of reducing the damage degree of the mounting surface as much as possible, andthe possibility of effective architectural acoustic reconstruction is increased for air film museums and other places with soft mounting surfaces.

Description

technical field [0001] The invention belongs to the field of acoustic reconstruction equipment, and in particular relates to an inner riveted fixing fastener for acoustic reconstruction. Background technique [0002] Air film building refers to a building structure system that uses special architectural membrane materials as the shell, and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air film building and support the main body of the building. With the development of architecture, there is a new way of constructing gymnasiums - inflatable air membrane halls. Since the architectural form of the inflatable dome pavilion is a curved vault, the vault structure is prone to sound focusing and sound reflection, and the reverberation time in the venue is very long, generally as long as 5 seconds, which cannot be used for sound reinforcement. Therefore, a second sound reconstruction is required. However, for buildings...

Problems solved by technology

Since the architectural form of the inflatable dome pavilion is a curved vault, the vault structure is prone to sound focusing and sound reflection, and the reverberation time in the venue is very long, generally as long as 5 seconds, which cannot be used for sound reinforcement. Therefore, a second sound reconstruction is required

However, for buildings with soft installation surfaces such as dome pavilions, it is impossible to install them directly on the surface. Usually, we choose to build floor-to-ceiling columns inside the place, hang attractors or install them directly with adhesive spraying. These two methods All have certain defects (increased load, easy to fall off, and certain safety risks)

At present, the ideal way is to use the suspension structure to install directly on the soft installation surface, but none of the existing suspension structures can be directly used on the soft installation surface
