It meets the requirements of rapid construction of the main steel structure, can provide a firm working platform in a short time, and can adopt the flowing construction method of laying profiled steel plates on multiple floors and pouring concrete slabs layer by layer. The installation and laying of floor slabs are also required in large cantilevered building structures.

[0003] During the installation of the existing floor slabs, the bundled profiled steel plates are first stacked neatly according to the paving sequence. The plates are hoisted using soft slings or steel wire ropes. After the hoisting is in place, the floor slab starts from the starting paving line popped out by the steel beam and is positioned one by one along the paving direction. After reaching the control line, the plate joints should be appropriately adjusted, and the floor slab is positioned through one-time hoisting.

[0009] A separation component is installed on the upper side of the installation groove. The separation component includes an installation shell, a sliding shaft, a bottom plate, a pressing plate, a separation plate, and a pushing plate. The installation shell is fixedly connected to the upper side of the installation groove, and two sliding grooves are symmetrically formed inside. Both ends of the sliding shaft are slidably arranged inside the two sliding grooves. The middle parts of the bottom plate and the separation plate are staggered on the sliding shaft, with the bottom plate located below and the separation plate located above, and the sides are in a scissor shape. The bottom plate is fixedly connected to the sliding shaft, and the separation plate is rotatably connected to the sliding shaft. The front ends of the separation plate and the pushing plate are triangular, and the tails are also inclined. The pressing plate is triangular and fixedly connected to the top wall of the installation shell, with the tip facing the inside of the installation shell. The pushing plate is vertically and fixedly connected below the sliding shaft. During the rotation of the transmission plate, the pushing plate is driven to move.

[0010] Preferably, a reset component is arranged between the bottom plate and the installation shell, and the reset component is used to drive the separation component to move.

[0011] Preferably, the reset component includes a connecting plate and a reset spring. The connecting plate is vertically and fixedly connected to the end of the bottom plate, and the reset spring is fixedly connected between the connecting plate and the inner wall of the installation shell.

[0012] Preferably, a shaping component is arranged on the short side of the frame body, and the shaping component is used to shape the floor bearing plate.

[0013] Preferably, four vertically symmetric sliding openings are symmetrically formed on the short side of the frame body. The sliding openings are rectangular. The shaping component includes a shaping plate, side plates, and telescopic rods. The shaping plate is slidably arranged inside the four sliding openings, the side plates are fixedly connected to the ends of the four shaping plates, and the telescopic rods are fixedly connected between the middle of the side plates and the frame body.

[0014] Preferably, a plate placing component is arranged below the placing rack, and the plate placing component is used to move and lay the floor bearing plate.

[0015] Preferably, the plate placing component includes a bottom frame, a rotating shaft, a laying plate, and guide wheels. Two bottom frames are symmetrically and fixedly connected to the lower side of the short side of the frame body. The rotating shaft is rotatably arranged below the bottom frame. The side of the laying plate is fixedly connected to the side of the rotating shaft. Installation strip openings are equidistantly formed on the laying plate, and a plurality of guide wheels are rotatably arranged inside the installation strip openings.

[0016] Preferably, hanging frame components are symmetrically and rotatably arranged on the long sides of both sides of the frame body.

The bottom shaft is rotatably connected to the lower end of the limiting plate and is rotatably installed on the frame body. The connecting column is vertically and fixedly connected to the upper end of the limiting plate.

[0017] A usage method of an installation device for a large cantilevered steel bar truss floor bearing plate is as follows:

[0018] S1: Stack the floor slabs to be laid on the steel bar truss. Use a crane to stack the floor slabs inside the placement rack. The transmission plates at the four corners are used to provide a placement surface for placing the floor slabs. Limit the floor slabs by rotating the limit plates on the four sides. At the same time, connect the placement rack to the crane through the connecting columns;

[0019] S2: During the laying process, drive the placement rack to move horizontally through the crane, and the controller drives the drive shaft to rotate intermittently to drive the floor slab to move up and down;

[0020] S3: During the rotation of the conveyor belt, the transmission plate pushes the push plate to move, so as to insert the bottom plate and the separation plate that are merged at the front end into the gap between two floor slabs. As the sliding shaft moves, the upper end of the separation plate contacts the extrusion plate during the sliding process, so that the inner ends of the separation plate and the bottom plate approach each other, and the outer ends move away from each other, so as to separate the two overlapping floor slabs. The floor slab located below moves down as the transmission plate moves. When the bottom plate and the separation plate are retracted, the floor slab located above falls on the new transmission plate;

[0021] S4: When the floor slab located below moves to the middle, drive the shaping plate to move through the telescopic rod, so as to reshape the floor slab that may be deformed during the transfer process and ensure the laying and use effects;

[0022] S5: Drive the laying plate to be inclined through the rotating shaft. As the transmission component drives, the floor slab located at the bottommost falls onto the placement plate component. The multiple guide wheels on the laying plate drive the inclined floor slab to slide, and the floor slab moves with the crane and is smoothly laid on the steel bar truss.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. Adjust the distance between adjacent transmission plates according to the thickness of the floor slab. When the transmission plate at the top contacts the push plate, the tips of the bottom plate and the extrusion plate are exactly located at the gap between the two floor slabs. When the conveyor belt rotates and the separation component slowly retracts, the floor slab located above after separation falls on another transmission plate during the falling process, so as to separate the floor slabs. The effect of separating and driving the floor slab is achieved through one drive shaft, and the structure is simple and the effect is obvious;

[0025] 2. Drive the separated floor slabs apart through the transmission component, so as to perform different treatments. Transport the floor slabs by transmission, and a large number of floor slabs can be processed at the same time, reducing the installation and disassembly time and improving the transfer efficiency of the floor slabs;

[0026] 3. Since some floor decks may be deformed during transportation, in order to ensure the connection between the floor decks, the floor decks need to be reshaped to ensure the use effect. The shaping components are used to shape the floor decks moved to the middle. The floor decks are reshaped by the shaping plates moving on both sides, which improves the laying effect of the floor decks;

[0027] 4. The floor deck at the bottom falls onto the plate-setting assembly. Multiple guide wheels on the laying plate drive the inclined floor deck to slide. The floor deck moves with the crane and is laid steadily on the steel bar rack. The floor deck can be laid quickly, which improves the efficiency of installation. BRIEF DESCRIPTION OF THE DRAWINGS
