[0016] The construction method of the assembled platform structure based on the cantilever beam is characterized by comprising the following steps:

[0017] S1. Production of cantilever beams and supporting beams:

[0018] (1) Square steel is welded on a welding table in a processing plant, and a notch is provided on the top of the square steel.

[0019] (2) Place the cantilever beam I-beam on the square steel, and then insert the limit strip into the groove of the square steel. The two limit strips in the same square steel limit the position of the single cantilever beam I-beam. Then, weld the cantilever beam bottom plate on the cantilever beam I-beam, remove the limit strip, and obtain the cantilever beam.

[0020] (3) Place the I-beam of the support beam on another square steel, and then insert the limit strip into the groove of the square steel. The two limit strips in the same square steel limit the position of the single I-beam of the support beam. Then, weld the bottom plate of the support beam on the I-beam of the support beam, remove the limit strip, and obtain the support beam.

[0021] In this operation, the cantilever beam I-beam or the support beam I-beam is limited on the square steel by the limit bar, so as to avoid damage to the cantilever beam I-beam or the support beam I-beam structure, and at the same time ensure the stability of the cantilever beam and the support beam. Moreover, the limit bar is clamped in the notch of the square steel, and the limit bar can be quickly installed or removed, so that the cantilever beam and the support beam can be quickly and batch produced.

[0022] S2. Install the support frame on the foundation layer according to the construction drawings, and keep the support frame vertically set.

[0023] S3. Hang the support beam, hang the support beam on the support frame, then fix the bottom plate of the support beam on the wall, and then fix the I-beam of the support beam on the support frame.

[0024] S4. Hang the cantilever beam onto the supporting beam, and then fix the bottom plate of the cantilever beam on the second wall. At this time, the two adjacent cantilever beam I-beams maintain the same distance.

[0025] S5. Fabrication of concrete support structure in processing plant:

[0026] (1) Punch holes in the support base plate so that the support base plate is provided with evenly distributed through holes 2.

[0027] (2) Install the support base plate onto the vertically placed mounting plate, which is provided with a through hole three and a connecting hole connected to each other. At this time, the limit block of the mounting plate is embedded in the limit groove of the support base plate, and then the adjustment block is embedded in the through hole three of the mounting plate, and the adjustment block is moved to the position in the through hole three of the mounting plate, and then the limit bolt is screwed into the connecting hole, and the limit bolt is tightened against the adjustment block, and then the vertical steel bar is inserted into the through hole two of the support base plate, and the vertical steel bar is supported on the adjustment block, and then the bottom surface of the support base plate and the vertical steel bar are welded and fixed, and then the support base plate is removed from the mounting plate, and then the horizontal steel bar is welded between the vertical steel bars.

[0028] (3) The raised portion 2 of the supporting enclosure is embedded in the limiting groove of the supporting base plate from top to bottom, and then concrete is injected into the cavity of the supporting enclosure. Vertical and horizontal steel bars are arranged in the concrete, and then a connecting pipe is installed in the concrete, and the connecting pipe is supported on the supporting base plate. When the concrete is solidified, the connecting pipe is fixed in the concrete, and then a limiting piece is screwed into the threaded hole 2 of the connecting pipe to obtain a concrete supporting structure.

[0029] In this operation, the length of the vertical steel bars passing through the supporting base plate can be ensured to be consistent, so that the vertical steel bars are evenly stressed in the concrete, ensuring that the concrete has good strength.

[0030] S6. Hang the concrete support structure into the space between the two cantilever beam I-beams. The concrete support structure is supported on the support beam I-beams. Then the support base plate and the cantilever beam I-beams are fixedly connected.

[0031] S7. Turn the limit piece to adjust its height so that the top surface of the limit piece is flush with the top surface of the cantilever beam I-beam.

[0032] S8. Cut the steel plates to the designed size in the processing plant.

[0033] S9. Hang the steel plate and place it on the top surface of the cantilever beam I-beam. At this time, the top surface of the limiter supports the steel plate. Then screw bolt 1 into the steel plate and screw bolt 1 into threaded hole 1 of the limiter.

[0034] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0035] (1) The present invention adopts a support beam to support the cantilever beam, and adopts a support frame to support the support beam, so that the force received by the cantilever beam can be transmitted to the wall 1, and at the same time transmitted to the wall 2 through the support beam, and can also be transmitted to the foundation layer through the support beam and the support frame. The cantilever beam, the support beam and the support frame form an integral structure, and the cantilever beam will not be deformed or bent. When the steel plate is set on the cantilever beam, the bearing capacity of the entire assembled platform structure can be increased, and heavier installation equipment can be placed on the steel plate for factory construction.

[0036] The overall structure composed of the cantilever beam, the supporting beam and the supporting frame has a good bearing capacity. The cantilever beam and the supporting beam both support the concrete supporting structure and can quickly install a concrete supporting structure of a certain weight.

[0037] (2) The present invention sets a stopper in the concrete support structure. When the steel plate is suspended on the top surface of the I-beam of the cantilever beam, the steel plate is supported on the stopper, and then a bolt is screwed into the steel plate from top to bottom. The bolt is threadedly connected to a threaded hole of the stopper, so that the steel plate is fixed on the cantilever beam. This avoids damage to the structure of the cantilever beam, and screwing the bolt in from top to bottom has a large operating space and is convenient for fixing the steel plate.

[0038] (3) In the process of manufacturing cantilever beams and support beams, the present invention uses a limit bar to limit the cantilever beam I-beam or the support beam I-beam on the square steel to avoid damage to the cantilever beam I-beam or the support beam I-beam structure, while ensuring the stability of the cantilever beam and the support beam. In addition, the limit bar is clamped in the notch of the square steel, and the limit bar can be quickly installed or removed, thereby enabling the cantilever beams and support beams to be manufactured quickly and in batches.

[0039] Moreover, the present invention manufactures the concrete support structure in the processing plant, and then suspends and installs the entire concrete support structure, thereby avoiding the potential safety hazards caused by the on-site construction of the concrete support structure. Moreover, the length of the vertical steel bars passing through the supporting bottom plate can be ensured to be consistent, so that the vertical steel bars are evenly stressed in the concrete, ensuring that the concrete has good strength.
