Description

Technical Field

[0001] The invention relates to the field of building decoration, and in particular to a method for installing an outer surface of an ultra-high structural column. Background Art

[0002] In some large exhibition halls, concert halls and other places, due to the large internal area and high internal height of the buildings, the single-story height of some buildings can reach more than 20 meters. Columns are usually installed as structural supports. In the later decoration process, the outside of the columns will also be decorated. Common ones include painting the outside of the columns and installing decorative panels.

[0003] Common decorative panels such as stone, aluminum panels, and composite decorative panels require a lot of work to install due to the high height of the columns. Although the installation workload is reduced by using relatively large decorative panels, the weight of a single decorative panel increases, making it more difficult to position and install at high altitudes.

[0004] When using relatively large-area decorative panels for installation, it is also necessary to use lifting equipment and climbing equipment for assistance. Common lifting equipment includes cranes, and climbing equipment includes articulated boom aerial work platforms. During the installation process, the decorative panel is lifted by the crane to the installation position. The construction personnel use the climbing equipment to adjust the position of the decorative panel to the installation position and fix it. Since the area of ​​a single decorative panel is relatively large and the weight is relatively heavy, the size of some decorative panels can reach 2420×3740mm and the weight can reach 700kg, which makes it difficult to adjust the positioning and install and fix.

[0005] In addition, during the construction process, since the ceiling, walls and other areas around the structural columns also need to be constructed, a full-floor scaffolding will be set up around the structural columns, which makes it impossible to use a crane to lift the decorative panels around the structural columns. Summary of the invention

[0006] In order to solve the problem that it is difficult to install the outer side decorative panels of high structural columns and it is inconvenient to use a lifting crane, the present invention provides a method for installing the outer side finishing of an ultra-high structural column, which is convenient for hoisting and installing and adjusting the decorative panels in a relatively narrow space.

A steel frame 2 is installed on the outer side of the structural column 1, and a decorative panel 6 is installed on the outer side of the steel frame 2.

[0040] More specifically, the steel frame 2 forms a functional space 5 for laying out the air duct 3 and the fire-fighting pipe system 4 on one side of the structural column 1. The air duct 3 and the fire-fighting pipe system 4 are integrated and installed in the functional space 5. The fire valve system of the fire-fighting pipe system in the functional space is provided with a fire door 7. The fire door 7 is arranged at a position close to the ground for easy operation of the fire-fighting pipe valve system after opening.

[0041] like Figure 5 and Figure 6 As shown, the decorative panel 6 includes a decorative surface layer 6-1, a metal back plate 6-2, and a supporting frame 6-3. The decorative surface layer 6-1 is fixed to the front side of the metal back plate 6-2, and the supporting frame 6-3 is fixed to the rear side of the metal back plate 6-2; hangers 6-4 are symmetrically installed on both sides of the supporting frame 6-3, and a decorative panel is provided with hangers 6-4 on at least the upper two sides and the lower two sides; the hanger 6-4 includes a plate structure and a mounting groove 6-5 which is provided with a downward opening of the plate structure.

[0042] In one embodiment, the decorative surface layer 6-1, such as an inorganic artificial stone panel, can be fixed on the metal back plate 6-2 by bonding or screw connection. The metal back plate 6-2 is such as a honeycomb aluminum panel. The support frame 6-3 is welded with galvanized steel pipes to form a frame structure, and the support frame 6-3 and the honeycomb aluminum panel are connected by angle codes.

[0043] like Figure 7 and Figure 8 As shown, a transversely arranged screw rod 2-1 and a mounting plate 2-2 for mounting the screw rod 2-1 are arranged on the outer side of the steel frame 2 corresponding to the hanger 6-4, two mutually parallel mounting plates 2-2 are arranged corresponding to each screw rod 2-1, and a mounting hole 2-3 for mounting the screw rod 2-1 is arranged on the mounting plate 2-2.

[0044] Each decorative panel 6 is pre-layouted and installed at a certain position in the early design stage. The position of the installation panel is preliminarily determined according to the layout position. During the process of adjusting the position of the decorative panel, the position of the decorative panel is measured with the help of a total station and adjusted to the set position. Layout can be achieved through BIM means, such as common tools such as Autodesk Revit software and Rhino software.

[0045] The steel frame 2 forms a rectangular frame on the outside of the structural column 1. The height of the rectangular frame is set along the height direction of the structural column, the width of the rectangular frame is set along the width direction of the structural column, and the length of the rectangular frame is set along the direction of the structural column toward the functional space 5. A splicing groove is set on the edge of the decorative surface layer 6-1 at the corner position of the steel frame.

[0046] The steel frame 2 is arranged along the height direction of the structural column, and the upper end of the steel frame 2 extends to a position close to the upper end of the structural column. An electric hoist 8 is installed near the top of the steel frame 2. A cantilever bracket 9 for hanging the electric hoist 8 is arranged near the top of the steel frame 2. The cantilever bracket 9 is cantilevered relative to the outer side of the steel frame 2, and the electric hoist 8 is suspended and installed below the cantilever bracket 9. Figure 1 As shown; the decorative panel 6 is lifted to a preset installation height by an electric hoist 8, the decorative panel 6 is moved relative to the screw 2-1 so that the decorative panel 6 is at a set installation position, the decorative panel 6 is moved so that the installation groove 6-5 of the hanger 6-4 is buckled on the screw 2-1 from above, and the decorative panel 6 is installed sequentially from bottom to top along the structural column 1.

[0047] The overhang bracket 9 can be fixed to the side of the steel frame by welding. Considering that the overhang bracket 9 will basically no longer be used after the decorative panel 6 is installed, a transverse mounting frame 10 is installed near the upper end of the steel frame 2 in this embodiment, and the overhang bracket 9 is assembled and installed on the side of the transverse mounting frame 10. The transverse bracket can be a part of the steel frame itself or a structure installed separately on the basis of the steel frame.

[0048] like Figure 2 and Figure 3 As shown, the transverse mounting frame 10 includes two parallel horizontal bars, and the cantilever bracket 9 includes a first support bar 9-1, a second support bar 9-2 and a third support bar 9-3. One end of the first support bar 9-1, one end of the second support bar 9-2 and one end of the third support bar 9-3 are perpendicular to each other and connected and fixed; the third support bar 9-3 is perpendicular to the first support bar 9-1 and the opposite end of the second support bar 9-2, and a hanging part for hanging the electric hoist 8 is provided. The hanging part, such as a ring, a column, a hole and other structures, provides a connection for the installation of the electric hoist; the first support bar 9-1 and the second support bar 9-2 are respectively installed with a clamping member 11, and the clamping member 11 is clamped and fixed on the cross bar. In this embodiment, the cantilever bracket 9 is made of square steel pipes welded.

[0049] In one embodiment, the suspension portion is Fig.11 As shown, a downwardly opening U-shaped groove 9-4 is provided at the end of the third support rod 9-3, an H-shaped groove wheel 9-6 is provided in the U-shaped groove 9-4, a fixing plate 9-7 is welded and installed along the outside of the U-shaped groove, the fixing plate 9-7 is arranged in a U-shape along the outside of the U-shaped groove, the fixing plate 9-7 extends downward near the opening of the U-shaped groove on both sides of the U-shaped groove 9-4 and forms a central axis mounting hole 9-8, a central axis spanning the opening of the U-shaped groove is installed in the central axis mounting hole 9-8, the central axis passes through the axis center of the H-shaped groove wheel 9-6, and the H-shaped groove wheel 9-6 is installed in the U-shaped groove 9-4 through the central axis; the upper end of the electric hoist 8 is matched with the H-shaped groove wheel 9-6 to provide a hanging ring 8-1, and the hanging ring 8-1 is suspended on the H-shaped groove wheel 9-6.

[0050] Preferably, the H-shaped wheel groove 9-6 should maintain a certain safety distance from the end of the third support rod 9-3. In one embodiment, the H-shaped wheel groove 9-6 maintains a distance of 60-80 mm from the end of the third support rod 9-3.

[0051] Preferably, a reinforcing diagonal brace 9-5 is connected between the first support rod 9-1 and the second support rod 9-2, between the first support rod 9-1 and the third support rod 9-3, and between the second support rod 9-2 and the third support rod 9-3, respectively, so as to form a stable triangular support structure on three mutually perpendicular surfaces, avoid deformation of the overhanging bracket when the decorative panel is adjusted laterally, and increase the stability and safety of the hoisting process. In this embodiment, the reinforcing diagonal brace 9-5 is welded with a square steel pipe to connect the first support rod 9-1, the second support rod 9-2, and the third support rod 9-3.

[0052] A clamping member 11 is respectively provided at a position close to both ends of the first support rod 9-1 and at an end of the second support rod 9-2 away from the first support rod 9-1.

[0053] The clamping member 11 is in a U-shaped structure with its opening downward, and is buckled onto the crossbar through the U-shaped structure. Then, through bolts are installed at the opening of the U-shaped structure to clamp and fix the clamping member 11 onto the crossbar.

[0054] As a preference, Figure 7 As shown, the longitudinal depth of the mounting groove 6-5 is greater than the diameter of the screw rod 2-1; a threaded barrel 6-6 is provided above the mounting groove 6-5 on one side of the plate structure, and a height adjustment bolt 6-7 which is threadably matched with the threaded barrel 6-6 is installed in the threaded barrel 6-6. The decorative panel 6 is moved laterally along the screw rod 2-1 to a set position in the horizontal direction. After the mounting groove 6-5 is buckled on the screw rod 2-1, the lower end of the height adjustment bolt 6-7 presses against the screw rod 2-1 from above. The height adjustment bolt 6-7 is adjusted to adjust the height of the decorative panel 6 to the set position in the height direction.

[0055] Furthermore, if Figure 8 As shown, a locking nut 2-4 is also provided on the screw rod 2-1, and the locking nut 2-4 is located on one side of the threaded tube 6-6 provided on the plate structure. After the position adjustment of the decorative panel 6 is completed, the locking nut 2-4 is screwed relative to the screw rod 2-1 so that the locking nut 2-4 is against the height adjustment bolt 6-7.

[0056] When installing decorative panels, within the same height of the rectangular frame, a single decorative panel is set along the width direction of the rectangular frame, and at least two decorative panels are set along the length direction of the rectangular frame; priority is given to installing decorative panels close to the structural columns.

[0057] When installing the decorative panel 6, a single decorative panel 6 is set along the width direction of the rectangular frame within the same height of the rectangular frame, and at least two decorative panels 6 are set along the length direction of the rectangular frame; the decorative panel 6 close to the structural column 1 is installed preferentially to facilitate the adjustment of the height adjustment bolts 6-7 when installing a circle of decorative panels within the same height range. The decorative panels of the same circle in the height direction are located close to the functional space, and personnel can enter the functional space to operate the height adjustment bolts 6-7.

[0058] When the decorative panel 6 is hoisted, the electric hoist 8 is connected to the decorative panel 6 through the strap 12 or the plate clamping mechanism 13. In order to make the process of hoisting the decorative panel by the electric hoist more clear, the hoisting process is schematically described as follows:

[0059] In one embodiment, the electric hoist is connected by a strap, such as Fig. 9 As shown, the strap 12 passes through the bottom of the decorative panel and is connected to the strap 12 through the hook of the electric hoist. The decorative panel 6 is lifted up and close to the set installation position. The personnel adjust the horizontal position of the decorative panel at the corresponding height. For example, in the case of a full-house scaffold, the personnel can stand on the scaffold to operate. In the case of a relatively open area, the personnel can use a height-adjusting vehicle to operate. After the installation slot 6-5 of the decorative panel is buckled on the screw rod 2-1, the strap is removed, and the height position of the decorative panel 6 is fine-tuned by the height adjustment bolt 6-7.

[0060] In another embodiment, Fig.10 As shown, the plate clamping mechanism 13 is clamped at the upper end of the decorative panel 6, and the plate clamping mechanism 13 is such as a curtain wall lifting clamp. The rest of the process is basically the same as the lifting by the strap, and the clamping of the plate clamping mechanism 13 can be removed after the mounting groove 6-5 of the decorative panel is buckled on the screw 2-1.

[0061] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
