Box out mouth safety device solves the problems, such as hole covering, but its structure is complex, and not easy to install and use increases
Add the amount of labour, reduces construction efficiency.
Summary of the invention
In view of the deficiencies of the prior art, technical problem to be solved by the utility model is to provide a kind of construction sites
With reserved opening safety device, production is simple, and easy to use, coverage effect is good, reusable, can be effectively reduced
The security risk of construction site.
The technical scheme adopted by the utility model is that construction site reserved opening safety device, including consolidated by one
Due on the ground of reserved opening side fixed plate and an adjustable cover board composition hinged with the fixed plate for sealing
The capping door body of lid reserved opening, the adjustable cover board include a plate body and one with the work of the scalable connection of the plate body
Movable plate, the interior accommodating chamber being equipped with for accommodating movable plate of the plate body, is equipped with multiple when movable plate protrudes outwardly on plate body
When required length covers reserved opening, by the screw that movable plate is fixed, it is equipped in fixed plate and movable plate side and is convenient for worker
The hang plate of construction and walking.
Above-mentioned construction site reserved opening safety device, the fixed board width is 3 ~ 5cm, in fixed plate
At least provided with two bolts for fixed plate to be fixedly connected with reserved opening side ground, it is equipped with and is used in capping door body
The handle that capping door body is started.
Above-mentioned construction site reserved opening safety device, the screw along adjustable cover board length direction simultaneously
Column setting is two rows of, and the counterbore being adapted to the screw is offered on plate body.
Above-mentioned construction site reserved opening safety device, it is in 60 ° of inclinations that the capping door body, which is equipped with a plurality of,
For warning the warning varnish-treated tape of worker, the wide 25cm of every warning varnish-treated tape.
Above-mentioned construction site reserved opening safety device is equipped with rubber on plate body and movable plate bottom surface
Layer.
The utility model construction site is to pass through a fixed plate and one with the beneficial effect of reserved opening safety device
The capping door body of hinged adjustable cover board composition covers reserved opening with fixed plate, and the safety for avoiding reserved opening is hidden
Suffer from, adjustable cover board is made of a plate body and one with the movable plate of the scalable connection of plate body, is covering different size of reserve
When hole, by the flexible of movable plate, change the length of capping door body, adapt to different reserved openings, it is reusable, it is not necessarily to
It makes again, has saved material, reduce the amount of labour of worker, improve construction efficiency, and structure is simple, can be widely popularized makes
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Fig. 3 is the structural schematic diagram that movable plate is connect with plate body.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the utility model.
