Detailed Description
In order to make the content of the present invention more easily and clearly understood, the present invention will be further described in detail with reference to the following embodiments in conjunction with the accompanying drawings.
Referring to fig. 1 to 2, the back supporting surface includes a horizontal supporting frame 1, which is a square frame having four corners in this embodiment. The horizontal supporting frame is made of profile steel. High-strength bolts 11 are welded to the lower portions of the four corners of the horizontal support frame, respectively. One end of the oblique supporting rod 2 is fixed below one corner of the horizontal supporting frame through welding, and the other end of the oblique supporting rod is fixed on the periphery of the top supporting pipe 3 located below the central portion of the horizontal supporting frame. In this embodiment, there are four diagonal braces, one diagonal brace being disposed below one corner of each horizontal support frame.
The support column includes support column and bottom suspension dagger, and its material is hollow steel pipe. And internal threads are respectively tapped on the inner walls of the upper support column and the lower support column. The upper end of the upper support column 4 is inserted into the top support tube 3 and fixed by a pin. Or may be secured by threads. A small section of steel pipe with an outer diameter larger than that of the upper support column is welded on the periphery of the lower end of the upper support column 4 to serve as a limiting boss 41. High-strength bolts 42 corresponding to four corners of the horizontal support frame are fixedly welded to the outer peripheral surface of the upper support column above the limit boss 41. The umbrella ribs 5 are inclined rods, the upper ends of the umbrella ribs are horizontally bent, and the lower ends of the umbrella ribs are vertically bent. The upper end of the umbrella rib 5 is fixed on the horizontal supporting frame through a bolt and a nut fixed on the horizontal supporting frame, the lower end of the umbrella rib is fixed on the upper supporting column through a bolt and a nut fixed on the periphery of the upper supporting column, and the limiting boss is supported by the lower end face of the umbrella rib to limit the support of the umbrella rib. Thus, the diagonal support rod 2 is positioned obliquely above the umbrella ribs. In this embodiment, the number of the ribs corresponding to the four corners of the horizontal support frame is four. The number of the oblique supporting rods and the umbrella ribs can be changed according to the shape of the horizontal supporting frame.
The lower extreme of lower support bar 6 is provided with base 7, and base 7 is horizontal plate column structure, and its area is bigger, can carry out the load diffusion, avoids stress concentration to cause ground destruction. If necessary, bolt holes are formed in the base 7, and the base is fixed on the ground by additionally arranging embedded foundation bolts 71 to fix the lower support columns.
The connecting rod 8 is provided with reverse external threads on the upper part and the lower part thereof respectively. A rotating handle 81 is provided at the central portion of the outer periphery of the link 8. The upper part of the connecting rod 8 extends into the lower end of the upper support column and is connected with the upper support column through threads, and the lower part of the connecting rod 8 extends into the upper end of the lower support column and is connected with the lower support column through threads. The distance between the upper and lower supporting columns can be adjusted by rotating the connecting rod 8 so as to adapt to different ground warehouse heights.
The horizontal support frame can be of a square structure, a round structure or other polygonal structures, and is directly contacted with the top plate of the basement to support the horizontal support frame. The horizontal supporting frame is supported by the oblique supporting rod, the umbrella ribs and the supporting columns, and the supporting strength is enhanced through the oblique supporting rod and the umbrella ribs. Because the ground storehouse is high different, realize the length adjustment of support column through the connecting rod, adaptable not high ground storehouse construction. The umbrella-shaped basement roof back-jacking reinforcing device is detachable, is assembled together when in use, can be detached into a plurality of small parts to be placed when not in use, and is convenient to process, place and transport.
When the top-returning reinforcing device is installed after the construction and the form removal of the top plate of the ground warehouse are completed, the upper supporting columns are pushed into the top supporting tubes and fixed through pins or other modes, then the umbrella ribs are fixed through bolts and nuts, the upper supporting columns and the lower supporting columns are connected together through the rotating connecting rods, and the heights of the supporting columns are adjusted to appropriate positions to form the complete top-returning reinforcing device for reinforcing the top plate of the ground warehouse.
Before each ground depot project is constructed, the load statistics and analysis (dead weight, vehicle load, construction load and the like) of a top plate of the ground depot are carried out, and the proper component size (profile steel, an oblique supporting rod, an umbrella rib, an upper supporting column, a lower supporting column, a connecting rod bolt and the like) and the required quantity, plane arrangement distance and position of the device are calculated. And after the concrete pouring and the form removal of the ground depot are finished, installing an umbrella-shaped ground depot top plate back-jacking reinforcing device at the designated position according to the design. The full framing can be installed in the erecting process, and only the full framing is dismantled when the formwork is dismantled. And after the integral construction of the three-star ground depot is finished, the top plate back-jacking reinforcing device of the three-star ground depot is dismantled.
