The installation method of the cylindrical steel structure bracket comprises the following steps: the top frame 2 is hung at a certain height above the bottom frame 1, the distance between the two ends of the top frame 2 and the bottom frame 1 is shortened by equipment, the width of the top gap 21 and the width of the bottom gap 11 are reduced, and the bending radian of the top frame 2 and the bottom frame 1 is increased. Referring to fig. 5 and 6, when the distance between each group of the second bottom limit plates 14 and the second top limit plates 24 is enough for the support frame 4 to enter, the support frame 4 is taken to move to a position between the corresponding top clamping plate 22 and the corresponding bottom clamping plate 12 along the horizontal direction until the assembly of all the support frames 4 with the top frame 2 and the bottom frame 1 is completed. At the moment, the bending limitation on the top frame 2 and the bottom frame 1 is released, the top frame 2 and the bottom frame 1 rebound due to elasticity, the radian of the top frame 2 and the bottom frame 1 is reduced, the bottom limiting plate II 14 limits the support frame 4 to leave the bottom frame 1, and the top limiting plate II 24 limits the support frame 4 to leave the top frame 2.
And then, the distance between the two ends of the top frame 2 and the bottom frame 1 is increased by using equipment, so that the widths of the top notch 21 and the bottom notch 11 are increased, the bent radian of the top frame 2 and the bottom frame 1 is reduced, the distance between each group of top clamping plates 22 and bottom clamping plates 12 is reduced, and the top clamping plates 22 and the bottom clamping plates 12 generate abutting force on the two sides of the support frame 4. Then the abutting frame 3 is taken out and arranged in the top gap 21 and the bottom gap 11, the bending limitation to the top frame 2 and the bottom frame 1 is loosened, the top frame 2 and the bottom frame 1 are kept in an expanded state due to the limit of the abutting frame 3, and abutting force is always kept between the top clamping plate 22 and the supporting frame 4 and between the bottom clamping plate 12 and the supporting frame 4. At the moment, the upper end of the support frame 4 is reliably limited by the top clamping plate 22, the first top limiting plate 23 and the second top limiting plate 24, the lower end of the support frame 4 is reliably limited by the bottom clamping plate 12, the first bottom limiting plate 13 and the second bottom limiting plate 14, and even if welding or bolt fixing is not carried out, the support frame 4 is firmly combined with the top frame 2 and the bottom frame 1.
And finally, welding and fixing the contact positions of the components to finish the installation of the steel structure support. In another embodiment, the components are fixed by drilling holes and screwing bolts. No matter which kind of fixed mode, because between top splint 22 and support frame 4, remain throughout between bottom splint 12 and support frame 4 and support the power of supporting, its steadiness has reduced the requirement to welding or bolt fastening steadiness, even welding quality has the flaw, has a small amount of bolts and insufficiently screws up, this steel structure support still has high steadiness.
Can further increase the steel construction in order to improve the steadiness on this steel structure support's basis. Riveting iron sheet, installation door or discharge gate outside this steel structure support, at top installation roof, behind bottom mounting plate, this steel structure support further forms the container and supplies in-service use.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
