Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for lowering steel truss floor decks with large height difference for lifting platforms. Background Technology

[0002] A steel truss floor deck is a composite load-bearing slab that connects a steel truss to a base plate by resistance spot welding. Its main structure includes steel bars for the top chord, bottom chord, and web members, which are connected by resistance spot welding to form a truss, and then connected to the base plate to form a floor deck.

[0003] A search revealed Chinese patent CN215802558U, which discloses a lifting plate node structure for a steel truss floor deck. The structure includes a lifting plate body, a floor deck body positioned on top of the lifting plate body, and L-shaped connecting plates fixedly connected to the top of both sides of the floor deck body. The bottom of the L-shaped connecting plates contacts the lifting plate body. Moving rings are provided on the front and back sides of the lifting plate body, located on the outer side of the floor deck body. A swing fastening frame is movably connected to the outer side of each moving ring via a pivot. The inner side of the swing fastening frame contacts the L-shaped connecting plates. A horizontal plate is fixedly connected to the top and bottom of the inner side of each moving ring, and the back of the horizontal plate is slidably connected to the lifting plate body.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] The aforementioned patents strengthen the connection between steel truss plates, but the process of manufacturing floor decking requires multiple welding operations and occupies a large area. This not only complicates the operation but also reduces construction efficiency and makes it difficult to guarantee construction quality, thus presenting certain limitations. Utility Model Content

It also includes:

[0026] Side sealing plate 2 is fixedly installed on one side of the steel truss plate 4. The bottom of the side sealing plate 2 is snapped into one end of the steel truss plate 1. The side sealing plate 2 can protect the side of the rib plate 3, prevent it from being damaged, and extend the service life of the rib plate 3.

[0027] Multiple ribs 3 are provided and are fixedly installed between the side sealing plates 2. The ribs 3 can effectively improve the strength and rigidity of the structural components, reduce deformation, and prevent structural instability.

[0028] Furthermore, multiple vertical reinforcing bars 7 are fixedly installed between the steel truss plate 1 and the steel truss plate 2, and each vertical reinforcing bar 7 is fixedly installed with a horizontal reinforcing bar 5, which improves the tightness of the truss plate connection and maintains the stability and firmness of the device.

[0029] Furthermore, studs 6 are fixedly installed between the bottom ends of the steel truss plate 1 and the side sealing plate 2, and multiple transverse steel bars 10 are fixedly installed on the surface of the steel truss plate 1. The studs 6 can be quickly installed using welding equipment, which reduces the complexity and error of manual operation and improves construction efficiency.

[0030] Furthermore, multiple reinforcing ribs 8 are fixedly installed on the steel truss plate 1, and multiple fixing blocks 9 are fixedly installed between the reinforcing ribs 8 and the surface of the steel truss plate 1, thereby improving the load-bearing capacity of the device, enhancing the service life of the steel truss plate 1, and strengthening the connection of the components.

The steel beams of the steel truss plate are reinforced with steel plates with a thickness of 8mm. The ribs 3 perpendicular to the beam span direction and the side sealing plates 2 parallel to the steel truss plate direction are connected by factory welding of the steel beams. The side sealing plates 2 are connected to the bottom plate of the steel truss plate 1 by studs 6. The studs 6 are installed inside the steel truss plate 1 and connected to the steel truss floor deck to form a whole.
