Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Examples
As shown in fig. 1-2, the present embodiment provides an underground large-span space disaster-response structure device (generally, the span is above 36m, called an underground large span), which includes a hidden-type upright column 2 and a control device;
The periphery of the hidden type upright post 2 is wrapped by flexible materials and is provided with a striking mark.
The contact place of the hidden upright post 2 and the middle plate adopts strengthening treatment.
The top of the hidden type upright post 2 is hinged with the bottom of the top large span structure 1, so that the hidden type upright post 2 can rotate along the hinged point (the bottom of the hidden type upright post 2 can be connected with the structure post 3 when the hidden type upright post is in a vertical position), and the bottom of the hidden type upright post 2 is connected with the middle plate.
The hidden upright post is hinged with the bottom of the large-span structure 1 at the top, so that the hidden post can be put down more conveniently.
