An auxiliary noise reduction device for a construction site

Abstract

This utility model provides an auxiliary noise reduction device for construction sites, relating to the technical field of noise reduction devices. It addresses the problem that gaps exist at the flip position of a double-panel structure during use, resulting in reduced noise reduction effectiveness due to gaps in noise blocking. The device includes: an indirect frame; two sets of splicing plates are provided above the indirect frame; inner grooves are formed on the inner sides of the two sets of splicing plates; noise-reducing inner plates are fixedly inserted into the two sets of inner grooves after splicing; and gap-sealing brackets are fixedly connected to the interiors of the two sets of side-fixing slots. The integrated structure of the splicing plates and the noise-reducing inner plates, combined with sound-absorbing and sound-insulating materials, can absorb and block construction noise at multiple levels. The gap-sealing brackets, through the double fixation of the side-fixing slots and constraint grooves, tightly fit the gaps of the splicing plates, effectively preventing noise leakage from the joints. Compared to traditional open barriers, this significantly reduces noise pollution to the surrounding environment.

Description

Technical Field

[0001] This utility model belongs to the field of noise reduction device technology, and more specifically, it relates to an auxiliary noise reduction device for use in construction sites. Background Technology

[0002] With the acceleration of urbanization and the continuous expansion of the construction industry, noise pollution from construction sites is becoming increasingly serious. It can affect the daily lives of surrounding residents and even lead to noise pollution complaints and social conflicts. Currently, common noise reduction measures at construction sites mainly include setting up barriers, using low-noise equipment, and wearing earplugs. Traditional barriers are mostly made of rigid board structures, which can only achieve partial noise reduction through physical barriers and have poor absorption effect on high-frequency noise. Therefore, an auxiliary noise reduction device is needed to facilitate noise reduction at construction sites.

[0003] For example, application number 202420051036.1 relates to a noise reduction device for construction sites, including a lower plate and an upper plate. The beneficial effects are as follows: This utility model, by setting up an electrically controlled drive mechanism consisting of a lower plate, an upper plate, a lower connecting seat, an upper connecting seat, a winding belt, a drive motor, and a winding roller, enables the noise reduction device for construction sites to adopt a double-plate structure, allowing for flexible flipping and folding. During use, the drive motor can wind up the winding belt, generating a pulling force on the upper plate, allowing workers to more easily flip the upper plate with the assistance of this pulling force. The specific tilt angle of the upper plate can also be flexibly adjusted. During storage, the drive motor can unwind the winding belt, gradually reducing the pulling force on the upper plate, allowing it to flip downwards and achieve a folding effect with the lower plate, thus improving the flexibility and convenience of the noise reduction device.

[0004] Based on existing technology, the aforementioned technology improves the flexibility and convenience of noise reduction devices through the folding of a double-plate structure. However, when the double-plate structure is flipped, there are gaps at the flipping position, resulting in gaps in noise blocking and thus reducing the noise reduction effect. In addition, it requires a motor to drive the flipping process, but due to the large area required at the construction site, a large number of motors are needed, making the wiring difficult and costly. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model relates to an auxiliary noise reduction device for construction sites. This device addresses the issue that when a double-plate structure is flipped, gaps exist at the flipping position, resulting in reduced noise reduction effectiveness. Furthermore, the flipping process requires a motor, which, due to the large area required at construction sites, necessitates a large number of motors, leading to high installation costs.

At the same time, the splicing method avoids the use of redundant equipment and effectively reduces the installation cost of the equipment. Attached Figure Description
