Description
Technical Field
The utility model relates to the field of building design of civil building attached civil air defense basements in building engineering, in particular to a foldable collapse-preventing shed frame device for an outdoor entrance and an outdoor entrance of the civil air defense engineering.
Background
At present, the civil air defense engineering level-shifting conversion system is quite mature, and the application of professional equipment can realize rapid and safe level-shifting in use function. Many new technical new devices are continuously updated and put into application, the conversion workload is less and less, the conversion steps are simpler, the operability and the practicability of peace and war conversion are greatly improved, the existing collapse prevention shed frame is divided into a reinforced concrete collapse prevention shed frame and a steel structure assembled collapse prevention shed frame, the former one-step construction is needed, the peace and war conversion is not needed, the main defects are that the number of stairs on the ground is more, the construction is not coordinated with the landscapes of a community, the latter one-step construction is not needed, only embedded parts are needed to be lowered for construction in advance, and other components are assembled and combined to form the collapse prevention shed frame when the construction is needed; the main defects are that professional construction teams are required for assembly construction, assembly members are generally prepared in place during engineering inspection, the assembly members are extremely easy to lose and damage after being placed for a long time, and assembly cannot be carried out once the assembly members are required, so that the collapse-preventing shed frame is invalid.
For the above reasons, a foldable collapse-preventing shed frame device for an outdoor entrance of a civil air defense project has been developed.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, and provides a foldable collapse-preventing shed frame device for an outdoor entrance of a civil air defense project, which combines the advantages of a concrete collapse-preventing shed frame and an assembled collapse-preventing shed frame, has a simple structure, is provided with all components in place at one time, is in a closed and concealed state at ordinary times, is not easy to lose and damage, can be taken up by only needing a small amount of non-professional labor force for simple operation once being started, realizes quick conversion, meets the use requirement of the civil air defense project, and further improves the practicability and reliability of the civil air defense project.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a foldable collapse-preventing shed frame device for an outdoor entrance of a civil air defense project is composed of: the civil air defense entrance, the cover plate, the X-shaped supporting frame, the rocker, the spiral telescopic device and the steel column; the steel columns are evenly distributed on two sides in the upper end of the civil air defense entrance, the lower ends of the steel columns are correspondingly hinged with the civil air defense entrance, a cover plate is arranged on the civil air defense entrance, a pair of X-shaped supporting frames are arranged between the two sides of the cover plate and the civil air defense entrance, a rocker is arranged between the lower ends of the left sides of the pair of X-shaped supporting frames, a rocking handle of the rocker is located on the outer side of the cover plate, a spiral telescopic device is arranged in the middle of the rocking rod, the tail ends of telescopic rods of the spiral telescopic device are connected to a connecting shaft between the pair of X-shaped supporting frames, the rocking rod drives the cover plate to ascend or descend through the spiral telescopic device and the pair of X-shaped supporting frames, and a bolt is arranged between the upper end of the steel column and the cover plate.
The spiral telescopic device is a damping spiral telescopic device with a locking safety mechanism.
The upper surface of the cover plate 2 is paved with landscape decoration.
The beneficial effects of the utility model are as follows: the device is mainly aimed at a civil air defense entrance needing to consider collapse prevention, is in a closing state at ordinary times, and is used for paving the landscape decoration of the turf on the upper part of a cover plate, when the device is needed to be used, a rocker on the side face is rocked to drive a spiral telescopic device, a telescopic rod of the spiral telescopic device stretches outwards to push an X-shaped supporting frame to jack up the cover plate, after the cover plate is lifted to a specified height, steel columns are respectively pulled up, the steel columns are fixed with a top cover plate through bolts after standing, and after all the upright columns are lifted and fixed, the assembly of the collapse prevention shed frame is completed, so that the civil air defense outdoor entrance plane-to-war conversion is completed; when the civil air defense engineering is not used, the outdoor entrance and the outdoor entrance can be closed and beautified, the outdoor entrance and the outdoor landscape are well integrated, when the civil air defense engineering is needed to be used, the anti-collapse shed frame can be quickly assembled, the use requirement of the civil air defense is met, the horizontal conversion can be simply and efficiently completed, and the use requirement of the civil air defense engineering is met, so that the practicability and the reliability of the civil air defense engineering are improved.
