Description

An easy-to-install sound barrier

technical field

The utility model relates to an easy-to-install sound barrier, belonging to the field of traffic environmental protection, in particular to a sound barrier.

Background technique

Sound barriers are mainly used for sound insulation and noise reduction of highways, highways, elevated composite roads and other noise sources, which can significantly reduce the impact of road noise on the surrounding environment.

There is a huge demand for sound barriers on expressways or high-speed railways. In many cases, it is necessary to continuously install sound barriers for tens of hundreds of kilometers. At present, the sound barriers are mainly composed of columns and unit panels. During the installation process of the sound barriers, the staff must install the columns After it is fixed on the ground, the unit board is fixed on the column with nuts or iron wires.

The height of the sound barrier is higher than the height of the average person, but during the installation process, the bolts on the top of the sound barrier must be firmly fixed, otherwise the unit plate will fall off, which is very likely to cause the car to crash and die. The consequences are unimaginable, but the staff installed piece by piece The sound barrier even needs to climb to a higher position to fix the unit board, which is time-consuming and labor-intensive, and the work efficiency is poor.

Utility model content

In order to overcome the above technical problems, the utility model proposes an easy-to-install sound barrier.

In order to achieve the above-mentioned technical purpose, the technical solution provided by the present utility model is: an easy-to-install sound barrier, comprising: a column, a card slot, a unit plate and a fixing card; two of the columns are vertically arranged, and the two columns are symmetrical on top of each other. Two card slots are provided, the card slots can be rotated relative to the upright column, a unit plate is installed between the two opposite card slots, and a fixed card is installed between the upright column and the card slot to prevent the card slot from rotating.

The left and right ends of the card slot are provided with several fixed ends, and the fixed ends are provided with through holes matched with the fixed cards.

The upright column is provided with an open slot adapted to the fixed end.

The fixing card includes: an anti-falling bolt group and a fixing frame; the fixing frame is arranged vertically, and several anti-falling bolt groups are fixed on the fixing frame from top to bottom, and the anti-falling bolt group includes a sliding connection with the column. The guide piece and two anti-drop bolts fixed on the guide piece, the anti-drop bolts are adapted to the through holes.

The lower end of the card slot is provided with an opening for installing the unit board, and a closing plate is arranged at the opening of the card slot.

A plurality of reinforcing members are arranged between the two oppositely arranged card slots, and the reinforcing members are used to fix the unit board.

Nuts are installed on the anti-fall bolts at the lowermost end of the anti-fall bolt group.

Compared with the prior art, the utility model has beneficial effects as follows:

1. The utility model adopts a rotatable card slot for installation, which is convenient for the staff to quickly install the unit board in the card slot during the installation process. At the same time, combined with the fixed card, two personnel can achieve rapid installation, saving work Personnel need to climb to a high place to fix the unit board, which improves the work efficiency and safety factor without reducing the stability of the installation.

2. The fixing card of the utility model adopts the form of an anti-falling bolt group and a fixing frame, so that the staff can quickly insert the anti-falling bolt into the through hole, and at the same time, the lowermost anti-falling bolt has the function of fixing the anti-falling bolt group. In addition, the fixed end mainly bears the force between the unit plate, the slot and the column, and the anti-drop bolt mainly prevents the fixed end and the column from falling off, which can ensure the stable connection between the slot and the column.
