[0024] <Example>

[0025] like Figure 1 As shown, a round column facing structure 100 is wrapped around the outside of a steel column body 20 , and includes two GRC column facing units 10 and two curved stainless steel facing panels 30 .

[0026] like Figure 2 As shown, the GRC column facing unit includes a skeleton and a GRC decorative panel 16 fixed to the periphery of the skeleton. The skeleton includes multiple layers of semi-encircling hoops 11, and arc brackets 12 are welded and fixed on each layer of semi-encircling hoops 11, and arc brackets 12 of all layers are welded and connected to axially arranged connecting brackets 13. The semi-encircling hoop 11 is a 10mm thick steel plate hoop semi-ring, the arc bracket 12 adopts a bent hot-dip galvanized square tube, and the connecting bracket 13 adopts a straight hot-dip galvanized square tube. The inner side of the GRC decorative panel 16 is provided with a plurality of embedded parts 15, and the embedded parts 15 are embedded in the GRC decorative panel 16 when it is cast. The length of the GRC decorative panel 16 is equal to the height of the column area to be decorated. A plurality of mounting brackets 14 are provided on each layer of the arc bracket 12, and the mounting bracket 14 is a hot-dip galvanized angle steel. The embedded parts 15 are welded to the mounting bracket 14 or fixed by bolts, so that the GRC decorative panel 16 is installed and fixed on the skeleton.

[0027] The two ends of the GRC decorative panel 16 are provided with a snap-in edge 16a protruding inward, forming a groove-shaped snap-in position. The semi-circular hoop 11 is bolted to form a full circle, so that the two GRC column decorative units 10 are connected and wrapped around the surface of the column 20. Figure 1As shown, in the round column facing structure 100, a curved stainless steel facing panel 30 is installed at the gap between two GRC column facing units 10 through the snap-fitting edge as a closure.

[0028] This embodiment also provides a GRC column covering installation system for the above-mentioned round column covering structure. Figures 4 to 6 The GRC column cladding installation system shown illustrates the installation of one GRC column cladding unit, omitting the same installation of another GRC column cladding unit.

[0029] See also Figure 3 and Figure 5 The GRC column facing installation system includes: a GRC column facing unit 10, a top clamp 40, a guide pulley 50, a wire rope 60, a winch 70, a directional guide groove device 80, and an auxiliary pull rope 90.

[0030] The top hoop 50 is installed and fixed on the top of the column 20, and the guide pulley 50 is installed and fixed on the top hoop 50 by conventional means such as bolt connection or welding.

[0031] The winch 70 is fixed to the ground by chemical bolts, and the winch is an electric winch with a load-bearing capacity of 4 tons.

[0032] The directional guide groove device 80 is fixed at the root of the column 20. Figure 7 As shown, the directional guide groove device 80 includes an embedded plate 81 fixed to the ground by bolts, and a vertical slot is arranged on the embedded plate 81. The slot is composed of two channel steels 82 welded and fixed on the embedded plate 81. The two channel steels 82 are arranged opposite to each other in a notch and form a accommodating square cavity 83b, and two gaps 83a are formed between the two channel steels 82 in the vertical direction.

[0033] The top end of the GRC column facing unit 10 is provided with a hanging ring structure 1, and the bottom end 2 is provided with a plug-in structure 2. Figure 7 As shown, the plug-in structure 2 includes a plug-in square rod part 2a, and the square rod part 2a can be a length of a connecting bracket 13 set to an extended length, and the extended connecting bracket 13 is used as the plug-in square rod part 2a. The left and right sides of the plug-in square rod part 2a are welded and fixed with guide shafts 2b. The plug-in structure 2 is plugged in with the slot of the directional guide groove device 80: the plug-in square rod part 2a is inserted into the accommodating square cavity 83b, and the guide shafts 2b on both sides are respectively located at the gap positions on both sides. During the hoisting process, since the plug-in structure 2 is plugged in with the slot, it can play a role as a guide rail to ensure that there will be no position deviation during the hoisting process.

[0034] In the GRC column cladding installation system, Figure 3 and Figure 5As shown, one end of the wire rope 60 is connected to the winch, and the other end is passed around the guide pulley 50 and connected to the lifting ring structure 1. The lifting ring structure 1 is connected with an auxiliary pull rope 90, which is a nylon pull rope and is used for workers to perform auxiliary operations, control the lifting to proceed smoothly, and avoid violent shaking.

[0035] The round column-wrapped facing structure 100 of this embodiment is constructed by the following column-wrapped facing assembly construction method, which includes the following steps:

[0036] Step 1: Use 3D scanning technology to measure the 3D size data of the column to be covered on site, merge the 3D model obtained after scanning with the design model, find out the error, adjust the drawing, and then generate the surface layer mold processing drawing and the skeleton processing drawing.

[0037] Step 2: prepare a casting mold according to the surface layer mold processing drawing, use the casting mold to cast the GRC decorative panel 16 as a whole, and embed the embedded parts 15 in the GRC decorative panel when it is cast and formed. Then perform decorative spraying.

[0038] Step three, making a frame according to the frame processing drawing, and assembling the frame and the GRC veneer panel into a GRC column veneer unit 10 in a factory.

[0039] Step 4: transport the GRC column facing unit 10 to the construction site, where a transport vehicle 200 may be used to assist in transportation and hoisting.

[0040] Step five, two sets of guide pulleys 50 are installed and fixed on the top of the column 20 through the top clamp 40, two directional guide groove devices 80 are correspondingly installed and fixed at the root of the column 20, and two winches 70 are correspondingly installed and fixed on the ground.

[0041] Step six, insert the bottom ends 2 of the two GRC column facing units 10 into the slots of the directional guide groove device 80, and hoist the top ends by connecting the winch 70, the guide pulley 50 and the wire rope of the lifting ring structure 1.

[0042] Step seven, after hoisting, each column is assembled with two GRC column finishing units 10: the semi-encircling hoops 11 of the two GRC column finishing units 10 are connected by bolts to form a full circle, so that the two GRC column finishing units 10 are connected and wrapped around the surface of the column 20, and the arc-shaped stainless steel decorative panels 30 are installed between the two GRC column finishing units for closing.

[0043] After the round column facing structure is installed, the GRC column facing just wraps the decoration area, and the GRC is cast from top to bottom as a whole, without joints. There is no joint between the two GRC column facing units 10, which avoids the problem of cracks in the later stage caused by the on-site splicing of GRC materials. In addition, after the round column facing structure is installed, after removing the top hoop 40 and the guide pulley 50, other construction can be carried out on the top of the column, such as ceiling construction.

[0044] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
