Abstract
Entrance to a cave safety device is reserved to the reinforced concrete floor for the safety protection at the entrance to a cave is reserved to the horizontal plane among the large -scale reinforced concrete frame structure, and it comprises protective steel plate, expansion bolts, articulated elements, connecting plate, and characterized by protective steel plate passes through the articulated elements with the connecting plate and is connected, and expansion bolts fixes and is reserving entrance to a cave next door for the connecting plate, protective steel plate will with reserve that the entrance to a cave covers and protective steel plate's neighboring than reserving the at least big 100mm in entrance to a cave limit. The utility model discloses simple structure, convenient to use, the cost is lower, can have enough to meet the need the use.
Description
Technical field
The utility model is applicable to the security protection of reinforced concrete floor reserved opening, is specially adapted to the security protection of horizontal plane reserved opening in the middle of large-sized reinforced concrete frame construction.
Background technology
Along with the fast development of China's economy, in the work progress of civilian construction and industrial construction, there are many large-scale reinforced concrete frame constructions.Have pipeline or equipment to need through floor in these large-sized reinforced coagulation frame constructions, therefore will reserve many holes on the floor of these frameworks, these holes have from 100mm to several meters.In work progress, these holes can cause safely hidden danger very to the life of constructor.In construction in the past, common way adopts plank or steel plate to cover.But the method in operation plank or steel plate often can be moved or lose, the plank that especially size is less or steel plate, protection effect is bad.
Summary of the invention
In order to reach the reliable protection to reinforced concrete floor reserved opening safety, turnover can be reached again use, save the requirement of material, the utility model provides and can have enough to meet the need use, lower-cost a kind of instrument for the security protection of reinforced concrete floor reserved opening.
Reinforced concrete floor reserved opening safety device, be made up of shoulder guard, expansion bolt, articulated elements, junction plate, it is characterized in that shoulder guard is connected by articulated elements with junction plate, junction plate expansion bolt is fixed on reserved opening side, and reserved opening will cover and the neighboring of shoulder guard 100mm at least larger than reserved opening limit by described shoulder guard.
The utility model structure is simple, and easy to use, cost is lower, can have enough to meet the need use, not easily be moved.It not only ensure that the safety of reinforced concrete floor reserved opening but also can have enough to meet the need use, and improves the installation effectiveness in the installation process such as pipeline, equipment.
