This utility model relates to construction protection articles for use field, is specifically related to the noise control crash helmet of a kind of job site, and it includes headpiece case, reflective membrane, glass fabric, raised body；Described headpiece case is semielliptical shape double layer hollow structure, hollow area between headpiece case bilayer is filled out and is filled with glass fabric, near its bottom end just to the raised body being fixed with two and the cavity of auricular concha shape adaptation of ear on curved wall inside headpiece case, hollow in raised body, hollow area in raised body is also filled out and is filled with glass fabric, the fixing one layer of reflective membrane that be sticked on the outside curve wall of headpiece case.This utility model can effectively reduce the noise intensity that construction operation personnel can hear at the construction field (site), it is prevented effectively from the acoustic trauma that construction operation personnel are subject to because of noise, in addition it can also play, at night, the effect that warning is reminded, and prevents the security incident caused because of the limited of job site lighting level.
Description
[technical field]
This utility model relates to construction protection articles for use field, more particularly to the noise control security header of a kind of job site
Helmet.
[background technology]
During engineering construction, often there is many unsafe factors, such as job site in job site
Noise is the biggest, if construction operation personnel do not take noise control measure, the audition of construction operation personnel to be easily subject to damage, in addition
When carrying on construction work at night, limited due to lighting level, construction safety inspector there is also during night routing inspection and arrived
From the shock potential safety hazard of job site apparatus.
[utility model content]
The technical problems to be solved in the utility model is to provide the noise control crash helmet of a kind of job site, and it can be effective
Reduce the noise intensity that construction operation personnel can hear at the construction field (site), be prevented effectively from construction operation personnel and be subject to because of noise
Acoustic trauma, it can also play, at night, the effect that warning is reminded in addition, prevents because job site lighting level limited
And the security incident caused.
In order to achieve the above object, the technical scheme that this utility model provides is: the noise control safety of a kind of job site
The helmet, it is characterised in that it includes headpiece case, reflective membrane, glass fabric, raised body；Described headpiece case is semielliptical shape
Double layer hollow structure, fills out in the hollow area between headpiece case bilayer and is filled with glass fabric, the song inside headpiece case
Face the wall and meditate upper near its bottom end just to being fixed with the raised body of two and the cavity of auricular concha shape adaptation of ear, during raised body is interior
Sky, also fills out in the hollow area in raised body and is filled with glass fabric, the outside curve wall of headpiece case is fixed being sticked
One layer of reflective membrane, the color of reflective membrane is yellow, and the whole outside curve wall of headpiece case is all wrapped by reflective membrane.
The beneficial effects of the utility model are: this utility model can effectively reduce construction operation personnel institute's energy at the construction field (site)
The noise intensity heard, is prevented effectively from the acoustic trauma that construction operation personnel are subject to because of noise, and it can also rise at night in addition
The effect reminded to warning, prevents the security incident caused because of the limited of job site lighting level.
[accompanying drawing explanation]
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein, 1-headpiece case, 2-reflective membrane, 3-glass fabric, 4-raised body.
[detailed description of the invention]
In example shown in the drawings, as it is shown in figure 1, the noise control crash helmet of a kind of job site, it is characterised in that
It includes headpiece case, reflective membrane, glass fabric, raised body；Described headpiece case is semielliptical shape double layer hollow structure, head
Hollow area between helmet housing bilayer is filled out and is filled with glass fabric, near its bottom on the curved wall inside headpiece case
Place just to being fixed with the raised body of two and the cavity of auricular concha shape adaptation of ear, hollow in raised body, hollow in raised body
Region is also filled out and is filled with glass fabric, the fixing one layer of reflective membrane that be sticked, reflective membrane on the outside curve wall of headpiece case
Color be yellow, the whole outside curve wall of headpiece case is all wrapped by reflective membrane.
After construction operation personnel wear upper this utility model, two protruding physical abilitys on headpiece case inner curve wall are supported
Live the cavity of auricular concha region of ear, owing to the hollow area in raised body and the hollow area between housing double-decker all being filled
Completely there is glass fabric, and glass fabric is a kind of good deadener, in the application of noise reduction appliances for labor protection field especially
Extensively, thus construction operation personnel can effectively reduce construction operation personnel after wearing this utility model and can listen at the construction field (site)
The noise intensity arrived, is prevented effectively from the acoustic trauma that construction operation personnel are subject to because of noise, and this is external when carrying on construction work at night, the helmet
Reflective membrane on hull outside curved wall can reflect the light that job site lighting is launched, and can play warning at night and remind
Effect, reflective membrane is yellow, and the personnel of job site hot work in progress operation can be allowed to identify each other residing position clearly
Put, prevent the security incident caused because of the limited of job site lighting level.
