The present invention also provides a construction method for the unloading platform, which is used for fixing the unloading platform on the structural beam of the building, including:

lifting the unloading platform to the position of the structural beam;

The unloading platform is fixed to the structural beam by matching the tension bolts with the bolt holes provided on the structural beam.

The on-site installation and removal process of the unloading tool involved in the present invention is as follows:

1. On-site installation

The unloading platform is processed off-site, and the construction site is installed and used by means of overall hoisting and reinforcement.

Assembly process and installation method:

Inspection → Lifting of unloading platform → Reinforcing platform → Installation of multi-layer boards and signs → Acceptance

(1) Check

Before the unloading platform is hoisted and installed, the site acceptance of the unloading platform shall be organized.

(2) Lifting of unloading platform:

Lift the unloading platform to the position of the structural beam.

The unloading platform can be hoisted only after it has passed the acceptance inspection. When hoisting, hang the hooks at the four corners first, and the four lead ropes of the hook should be of equal length to ensure the stability of the platform during the lifting process. When the platform is hoisted to the installation floor, slowly lower the platform, place the platform smoothly on the installation structural beam 3 and make the outer wedge-shaped support base 1022 close to the structural beam 3. After the platform is reinforced, the tower crane sling can be loosened.

(3) Reinforcement platform:

The unloading platform is fixed to the structural beam by matching the tension bolts with the bolt holes provided on the structural beam.

After the unloading platform is hoisted, use the combination of φ16 pair of pull bolts and connecting beams 5 to tighten the connecting beams 5 and structural beams 3 on the platform through the structural bolt holes. The bolts are made of 10mm thick steel plates as fixed gaskets. Use double nuts to fix, and the cantilevered unloading platform should be reinforced with at least three bolts.

After the bolts are tightened, the wedge-shaped support seat 1021 on the inner side of the unloading platform is wedge-fastened with the structural beam 3 using a triangular wooden wedge.

At the same time, a column 105 with a diameter of 48mm plus adjustable drag braces and structural floor slabs are used for fixed top braces. Put the steel pipe on the 200mm long C20 thick steel bar, straighten the steel pipe, and tighten the adjustable drag brace. And use a horizontal pull rod to connect the two uprights 105 to ensure that the platform is stable and free from shaking.

(4) Install hard protection and hang signs:

After the unloading platform is installed and reinforced, a baffle plate of hard material is arranged on the inner side of the inner railing of the protective net 202 . Then, on the obvious part of the platform, hang the signboard of the tonnage limit, the signboard of the platform operation rules and precautions, and the limit plate of the number of blocks.

(5) Check:

After the installation of the unloading platform is completed, a trial hoisting should be carried out first. During the trial hoisting process, if the bolts are loosened, the platform is twisted, the steel pipe supports fall off, etc., the secondary reinforcement should be carried out in time.

It can be officially used only after the acceptance is passed.

It should be noted that when the unloading platform is used to carry out the reverse transportation of the construction materials of the masonry project. Commanded by the signal worker, the tower crane lifts the autoclaved concrete aerated block to the unloading platform. After the materials are stabilized, the workers at the operation floor will transport the autoclaved concrete aerated blocks to the operation floor.

The use of the unloading platform involved in the present invention adopts a layer-by-layer lifting method, and the lifting process is: preparation before lifting → removal of fixing measures → lifting of the unloading platform → installation of the unloading platform → acceptance;

The lifting of the unloading platform involved in the present invention specifically includes the following steps: before lifting, remove the material on the platform, and a special person is responsible for the command, slowly lowering the hook of the tower crane and the lifting hook of the platform, and tightening the suspending rope slightly; The supporting steel pipe is removed, and then the reinforcement measures of the triangular wooden wedge, the tie bolt and the column 105 are removed; the unloading platform is lifted, and when a signal is sent, the platform is first moved horizontally to the outside to a safe distance outside the structure, and then it is steadily lifted to the upper floor at a constant speed. When the unloading platform is lifted, a warning area must be set up on the ground below, with striking signs and guards. The unloading platform shall be re-installed, reinforced, and used after the acceptance is passed.

2. On-site demolition

The on-site dismantling of the unloading platform involved in the present invention includes the following steps: when dismantling, firstly use a tower crane to mechanically pre-tighten the unloading platform, and pay attention to the balance of the lifting point to prevent the platform from falling from instability;

Slowly dismantle the supporting steel pipes and adjustable drag braces at the end of the platform. When dismantling, the operator should stand in the direction of the room, and it is strictly forbidden to stand on the unloading platform to dismantle the pole;

When the unloading platform is dismantled, a warning area must be set up on the ground below, with eye-catching signs and guards; the whole unloading platform is hoisted to the ground.

It should be noted that the unloading platform can be installed after the concrete of the main structure of the building reaches the design strength. The scope of application of the unloading platform is the masonry stage and the decoration stage, which is a relatively dangerous project and requires expert demonstration.

To sum up, the unloading platform used in the construction project according to the present invention does not need to reserve installation conditions in the structural construction stage, and is directly installed at the position of the turning beam on the wall structure. The bolt holes reinforced by the structural construction template are reinforced with steel pipes, adjustable drag braces and other materials, which are convenient for installation and disassembly and easy to use. At the same time, compared with the existing technology of this unloading platform, it also has the technical effects of shortened construction period, better quality perception, less material input and more environmental protection, lower cost, and convenient on-site installation and removal.
