Description

Technical Field

[0001] The present application relates to the technical field of prefabricated buildings, and in particular to a prefabricated floor slab installation device and installation method. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories such as floor slabs, wall panels, stairs, balconies, etc. are processed and manufactured in factories, and then transported to the construction site and assembled and installed on site through reliable connection methods.

[0003] When constructing prefabricated floor slabs, a tower crane is usually used to hoist a single prefabricated floor slab to the designed position. Construction workers catch the hoisted prefabricated floor slab on the construction floor and guide the tower crane to move the prefabricated floor slab accurately to the designed position. The tower crane hook is then removed from the prefabricated floor slab, thus completing the hoisting of the prefabricated floor slab.

[0004] Since the work surface of the floor to be installed cannot bear the temporary turnover placement of multiple prefabricated floor panels, usually only one prefabricated floor panel can be hoisted at a time, and the next one can only be hoisted and installed after the floor panel is installed in place by the crane. A building is usually equipped with only one tower crane. It takes a lot of time to accurately move the prefabricated floor panel to the designed position, which will reduce the efficiency of hoisting and assembling the prefabricated floor panel, making the hoisting and installation of the prefabricated floor panel a constraint on the construction period of the prefabricated floor panel project.

After the construction of the second-floor structural columns is completed, the first-floor structural top plate is hoisted and installed, that is, the second-floor structural bottom plate is constructed.

[0038] The efficiency of transporting and installing prefabricated floor slabs by tower crane is low. The prefabricated floor slab installation device of the present application is installed on the structural columns of the second floor to improve the installation efficiency of the prefabricated floor slabs.

The track beam 1 includes a first track 11 and a second track 12 which are arranged horizontally. The first track 11 and the second track 12 are respectively fixed on two adjacent rows of vertical members 100. The first track 11 and the second track 12 are in the same horizontal plane and are arranged correspondingly. The first track 11 and the second track 12 can be steel structures, specifically I-beams, C-shaped steels, square steel pipes or F-shaped steels with inverted cross sections. It should be noted that the vertical members 100 in the present application are not limited to vertical structural columns, but can also be temporary vertical support members or other structures capable of installing and fixing the track beam 1 of the present application. The vertical members 100 in the present application are only used to provide fixing points for the track beam 1, and the structural form is not limited.

[0040] In order to achieve stable installation of the first rail 11 and the second rail 12, the first rail 11 and the second rail 12 are connected to each intersecting vertical member 100 by high-strength bolts, and at least three connection points are set. It can also be achieved by pre-setting a detachable bracket on the vertical member 100.

[0041] A mobile receiving platform 2 and a hoisting truss 3 are installed on the track beam 1. The mobile receiving platform 2 is used to stack the prefabricated floor slabs 200, and the hoisting truss 3 is used to transport and hoist a single prefabricated floor slab 200.

[0042] Specifically, the mobile receiving platform 2 includes a plurality of support groups 21 arranged at intervals, the support group 21 includes a transverse support rod 211 and two vertical suspension rods 212, the two ends of the transverse support rod 211 are respectively connected to the two vertical suspension rods 212, one end of the vertical suspension rod 212 away from the transverse support rod 211 is slidably connected to the first track 11, and the other end of the vertical suspension rod 212 away from the transverse support rod 211 is slidably connected to the second track 12.

[0047] The lifting gantry 3 includes a horizontal drive assembly and a vertical drive assembly.

[0048] The horizontal drive assembly includes at least two sliding rails 31 arranged at intervals, and the two ends of the sliding rails 31 are respectively connected to the first rail 11 and the second rail 12 in a sliding manner. Specifically, the two ends of the sliding rails 31 are fixed with second traction pulleys 311, which are clamped above the first rail 11 and the second rail 12. By controlling the rotation of the second traction pulley 311, the horizontal drive assembly can be driven to move along the track beam 1. It should be particularly noted that the mobile receiving platform 2 and the hoisting truss 3 are respectively connected to different areas of the track beam 1 in a sliding manner. In the embodiment of the present application, the hoisting truss 3 is connected to the top wall of the track beam 1 in a sliding manner, and the mobile receiving platform 2 is connected to the side wall of the track beam 1 in a sliding manner.

[0049] The vertical drive assembly includes a support frame 32 and a hoisting and lifting device 33 for hoisting a single prefabricated floor slab 200.

The stacking height of the prefabricated floor 200 on the mobile receiving platform 2 is controlled, and the length of the branch rope 332 is reasonably set, so that when the main hoisting rope 331 is fully rolled up, the top surface of the prefabricated floor 200 stacked on the mobile receiving platform 2 is located below the prefabricated floor 200 hoisted on the hoisting gantry 3, so that the horizontal movement of the mobile receiving platform 2 and the horizontal movement of the hoisting gantry 3 do not interfere with each other.

[0053] Furthermore, the track beam 1 is arranged below the design height of the floor top plate, and the installation device of the prefabricated floor 200 of the present application does not interfere with the construction of the structural top plate and structural beams of this layer, thereby enabling the installation of the prefabricated floor 200 to be carried out without affecting the construction of the structural beams of this layer.
