Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a connection structure of sound insulation and noise reduction panels in construction projects. Background Art

[0002] Existing steel-structured buildings typically use metal corrugated wall panels or rock wool sandwich panels as exterior wall panels. However, while existing sandwich panels and metal corrugated wall panels offer excellent thermal insulation, they offer poor noise reduction when used as walls in industrial plants, logistics buildings, and office buildings. They fail to isolate most sounds within the building, thus failing to meet practical needs. Enclosures are devices that isolate the construction site from the external environment during construction, creating a relatively enclosed space. Enclosures are available in a variety of materials, are stable and aesthetically pleasing, and improve construction site safety. The use of enclosure devices is indispensable at construction sites, but most of the current enclosure devices have fixed structures. Although they can achieve sound insulation and noise reduction, they are not convenient to disassemble and assemble due to the large area they occupy. For example, Chinese patent document No. CN208618928U discloses a construction site noise reduction enclosure, which includes a frame, an outer baffle and a porous sound-absorbing panel. The outer baffle is provided on the side of the frame away from the construction site, and the porous sound-absorbing panel is provided on the side of the frame facing the construction site. The porous sound-absorbing panel can absorb the noise generated at the construction site, thereby reducing the impact of the construction process on surrounding residents. However, the frame of the noise reduction fence includes multiple unit frames and baffles. The frame components have a complex structure, are time-consuming and labor-intensive to assemble, have poor waterproof performance, and have limited connection strength. In addition, since the existing steel structure component steel plates are relatively thick, a large number of holes are required during on-site drilling and installation, which results in a large workload. In addition, the construction environment is limited, and the accuracy of the hole positions is difficult to guarantee. Limited by the structural characteristics of the noise reduction fence, it can only be used as a fence for enclosure and isolation, and cannot be directly connected to existing steel structure columns. It cannot be used as an exterior wall panel in the external protection of industrial plants, logistics buildings, and office buildings, which greatly limits its scope of use.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1:

The steel column 1 is an H-shaped steel column, and the steel column 1 includes a web 10 and flanges on both sides of the web 10. The fixing plate through hole 4 is located on the flange 6 on the front side of the web 10, and the fixing plate nut 3 is welded and fixed on the inner side of the flange 6 corresponding to the position of the fixing plate through hole 4. The central axis of the fixing plate nut 3 remains coaxial with the central axis of the fixing plate through hole 4. After the steel column 1 of the present invention is assembled and formed, a fixing plate through hole 4 is processed on the flange 6 of the steel column 1 by a CNC machine tool according to design requirements. After the fixing plate through hole 4 is drilled, the fixing plate nut 3 is welded. In order to ensure the welding position accuracy and welding quality of the fixing plate nut 3, a matching screw is installed when welding the fixing plate nut 3, and the screw is removed after welding is completed. Through factory prefabrication, processing errors are reduced, work efficiency is improved, and the workload of on-site drilling is greatly reduced, which can significantly speed up the construction progress and ensure construction quality. The noise reduction panel 2 riveted with the perforated sound-absorbing aluminum plate 17 has a simple structure and is quick and easy to install. In order to improve the sound absorption and noise reduction effect of the noise reduction panel 2, a perforated sound-absorbing aluminum plate 17 is fixed to the middle part of the inner side surface of the noise reduction panel 2 by rivets. The perforated sound-absorbing aluminum plate 17 can be made by opening sound-absorbing holes on an aluminum plate with a thickness of 0.25-0.7 mm. The diameter of the sound-absorbing holes can be selected in the range of 16 to 32 mm, and the opening rate is greater than or equal to 50%. By installing a sound-absorbing filler between the perforated sound-absorbing aluminum plate 17 and the inner side surface of the noise reduction panel 2, after the noise enters the cavity between the perforated sound-absorbing aluminum plate 17 and the noise reduction panel 2, the noise is further eliminated by the sound-absorbing filler, thereby reducing the impact of the noise in the building on nearby residents. The sound-absorbing filler can be specifically urethane foam plastic, rock wool or mineral wool according to the use occasion and needs. The sound-absorbing filler can also be micro-perforated foam ceramics. Micro-perforated foam ceramics have strong sound absorption and noise reduction capabilities and good fire resistance. Through the steel column 1 with the fixing plate through hole 4 and the fixing plate nut 3, and the noise reduction plate 2 with the perforated sound-absorbing aluminum plate 17, the utility model has a simple component structure, time-saving and labor-saving assembly, excellent noise reduction, heat preservation and waterproof performance, and high connection strength.
