Construction site enclosure wall device capable of falling dust

Abstract

The invention discloses a construction site enclosure wall device capable of falling dust. The construction site enclosure wall device comprises uprights, a wallboard and a rear support; the uprightsare respectively arranged at the left and right sides of the wallboard; the rear side of the lower end of each upright is provided with the rear support; the rear support comprises fixed hinged joints, hinged diagonal bars, a middle base and a screw rod; the fixed hinged joints are arranged at the positions, on the left and right sides of the wallboard, of the uprights; the positions, located on the opposite sides of the two uprights, of the fixed hinged joints are respectively hinged with the hinged diagonal bars; the hinged diagonal bars between two uprights extend backward and downward relatively and the middle base is arranged between the relatively close ends; the screw rod is arranged on the middle base; and a dust falling spray nozzle is arranged above the screw rod. According to the construction site enclosure wall device capable of falling the dust provided by the invention, the phenomenon that an auxiliary supporting point of an existing construction site enclosure wall is arranged right behind uprights is changed, and a supporting point is arranged behind two adjacent uprights, so that the uprights are supported in the front and rear directions, and the uprights are alsosupported in the left and right directions; and besides, the dust falling spray nozzle is arranged to carry out dust falling treatment in an area in the enclosure wall to prevent dust pollution fromdiffusing to the outside of the enclosure wall.

Description

technical field [0001] The invention relates to the technical field of construction site equipment, in particular to a construction site enclosure wall device capable of reducing dust. Background technique [0002] A construction site, that is, a construction site, is a place where construction projects are being developed and civil engineering is being carried out. The scope is often closed by hoardings, barbed wire or walls to restrict the entry and exit of personnel, materials, machinery and vehicles. The construction site fence is an important part of the construction site. According to the "Building Construction Safety Inspection Standard JGJ59-99", the standards for the construction site wall are as follows: the construction site must implement closed management, set up entrance and exit gates, formulate a guard system, and strictly enforce the entry of outsiders registration system. Set fences continuously around the construction site. The height of the fences on the...

Problems solved by technology

[0003] The current construction site fence generally includes uprights, rear brackets and wall panels. The uprights are evenly erected around the edge of the construction site. Wall panels are arranged between two adjacent uprights. , so the direction of the supporting force of the rear support to the column is generally in the front-to-back direction. For the support force in the left-right direction of the column, the rear support generally does not provide it, but is provided by the wall panel. After the extrusion force in the left and right directions is applied, such as the collision caused by material loading and unloading, it is easy to cause a large length of dominoes to collapse. This is a problem that needs to be solved urgently. Due to the flow effect, it is easy to overflow from the top of the fence, so it is best to install multiple dust suppression nozzles inside the extension line of the fence, and the water is supplied by the joint water pipe. Therefore, considering the existing structure of the fence and the functions it needs to achieve, a special design is proposed.
