Description

Technical Field

[0001] The invention relates to the field of building decoration, and in particular to a method for forming a large-area hyperbolic aluminum decorative plate. Background Art

[0002] In the prior art, large-area aluminum panels are usually installed on steel frames fixed with traditional self-tapping screws. It is necessary to bend the keel and the panel to form the final hyperbola. Both bends will form a bending deviation (there are deviations in the two installations and the positioning of the line), which will increase the error of the keel panel installation, increase the difficulty of installation and adjustment, and cause the installation surface to be not smooth. During construction, the keel is installed first, and then the panel block is installed. It is necessary to perform two high-altitude operations, two line layings, and two adjustments. There is an installation deviation in the keel installation, resulting in a large amount of adjustment for the panel installation and increased installation difficulty. If the keel is concave, it is necessary to increase the adapter. If the keel is convex, it will occupy the installation space of the panel. It is necessary to customize the adapter to increase the adjustment space. The convex keel will occupy the installation space of the panel, which will directly cause the panel to be unable to be installed. The panel curvature can only be changed during installation. Changing the panel curvature requires replacing the panel, or rework to change the convex keel to a concave one will affect the installed panel and make the panel difficult to install. Most of them have not achieved fully assembled installation. Due to the deviation of steel frame welding, the surface of aluminum plate often appears uneven, and the hoisting construction of large-area aluminum plate is difficult. Traditionally, steel pipes are used for bending to make the first keel of the curtain wall. The keel will rebound during the bending process, resulting in the bending degree not meeting the design requirements. In order to digest the deviation of keel installation, it is necessary to adjust the panel and splice the aluminum plate, making the curvature of the curved surface difficult to control. In some places, it will cause unsmooth concave and convex splicing angles to digest the deviation of the secondary adjustment installation of the panel, affecting the installation quality and appearance. In order to solve these problems, different installation solutions have also appeared in the industry, and various unsatisfactory places often appear during the installation. Especially for the installation and construction of a large-area hyperbolic aluminum decorative panel, not only is the installation difficult, there are quality problems such as welding deviation and rebound deviation of the bending steel pipe, but it is also difficult to make three-dimensional adjustments, and it is ultimately difficult to form a flat and smooth hyperbolic decorative effect. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide a method for forming a large-area hyperbolic aluminum decorative plate that can be installed flatly, smoothly, firmly, and three-dimensionally adjustable, and that reduces construction difficulty and improves construction quality.

[0004] To solve the above technical problems, the present invention adopts a method for forming a large-area hyperbolic aluminum decorative plate, which is characterized by comprising the following steps:

[0008] Step 4: transport several hyperbolic unit panels to the decoration site, hoist the hyperbolic unit panels one by one, and install them on the hyperbolic steel grid with threads. The hoisting position is adjustable; the adjacent aluminum plate panels between adjacent hyperbolic unit panels can be adjusted and plugged in;

[0009] Finally, a large-area hyperbolic aluminum decorative panel is formed.

[0010] As a preferred embodiment, each of the aluminum plate panels is a flat aluminum plate with both sides bent inward to form 90° edges, and a connecting profile is connected between the edges on both sides at both ends of each of the aluminum plate panels by a first bolt, and a connecting hole is provided on the upper surface of the connecting profile, and one side of an L-shaped angle code is adjustable and locked in the connecting hole on the upper surface of the connecting profile by a second bolt; the other side of the L-shaped angle code is connected to the curved steel plate by a third bolt, and the connecting position is close to the curved edge of the curved steel plate; the connecting hole on the L-shaped angle code is a long hole to facilitate the adjustment of the connecting position.

[0011] The adjustable plug-in structure of adjacent aluminum plate panels between two adjacent hyperbolic unit plates is: the L-shaped corner code on one of the aluminum plate panels extends a plug-in plate outward, and a connecting plate with a U-shaped plug-in groove is connected to the connecting wire profile at the end of the other aluminum plate panel. The plug-in plate is plugged into the U-shaped plug-in groove of the connecting plate 7 and can slide therein, thereby adjusting the position between the two adjacent aluminum plate panels.

[0012] A connecting profile is also provided in the middle of the aluminum plate panel of the hyperbolic unit plate, and a connecting hole is opened on the upper surface of the connecting profile. One side of an L-shaped angle code is locked in the connecting hole on the upper surface of the connecting profile with a second bolt so that the position can be adjusted; the other side of the L-shaped angle code is connected to the curved steel plate by a third bolt, and the connecting position is close to the curved edge of the curved steel plate; the connecting hole on the L-shaped angle code is a long hole to facilitate the adjustment of the connecting position.

[0013] A plurality of first U-shaped semi-threaded screws are movably sleeved outside the straight round steel pipe at intervals, and two screws of each first U-shaped semi-threaded screw pass through the curved steel plate and are fastened by a first nut, so that the curved steel plate can be connected to the straight round steel pipe along the length direction with adjustable connection position.

[0014] Through holes are provided at both ends of the straight round steel pipe; a large round tube of the grid is provided on the hyperbolic steel grid, the U-shaped part of the second U-shaped semi-threaded screw embraces the large round tube of the grid, and its screw passes through the through hole of the straight round steel pipe and is fastened with a second nut.

[0016] Compared with the prior art, the beneficial effects of the present invention are mainly:

[0017] The present invention adopts BIM three-dimensional laser scanning and modeling technology to reduce the problem of difficult layout of complex hyperbolic steel structures. The hyperbolic configuration of each unit plate is bent in one direction with an aluminum plate (bent by the aluminum plate manufacturer), and the curved surface configuration is made with a cut curved steel plate in the other direction. The curved surfaces in the two directions form a hyperbola. The strip-shaped aluminum plate is assembled on the ground along the curved edge of the steel plate, and the straight and curved edges are combined to provide a guarantee for the subsequent overall hoisting. At the same time, the cut curved surface of the steel plate perfectly solves the quality problem of the rebound deviation of the bent steel pipe; the hyperbolic shape of the final surface layer is formed when all unit plates are assembled. The construction technology of overall hoisting and installation of unit plate assembly is adopted, and the one-time hoisting and installation only requires one high-altitude operation and one layout. The installation is adjusted in place at one time, which reduces high-altitude operations, solves the quality control problem of bulk components, simplifies construction, and ensures construction quality. When installing the unit block, it is only necessary to adjust the straight edge of the top of the steel plate or the top round tube according to the angle of the drawing to achieve the design and construction effect. The construction is simple and the construction deviation is easy to control. It is connected to the main structure with a clamp, and the entire assembly and installation is assembled using threaded connections. The full bolt installation structure realizes prefabricated installation and is convenient for three-dimensional adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2-4 The decorative installation structure shown in the figure. In order to form the above decorative effect, the following steps are adopted.

[0029] Step 1: Go to the decoration site and use a BIM three-dimensional laser scanner to perform a structural scan on the hyperbolic steel grid 200 that has been formed; image and model the obtained hyperbolic steel grid structure in the computer; then decompose the aluminum panel according to the unit plates and lay out and cut the materials by computer; model the equally spaced curved steel plates according to the computer-laid hyperbolic shape of the aluminum panel; then cut the curved steel plates into sections and lay out and cut the materials; finally, lay out and cut the straight round tubes accordingly.

[0030] Step 2: Process each aluminum panel 10, curved steel plate 20, and straight round steel tube 30; wherein each aluminum panel 10 is consistent with the hyperbolic surface at its location, and is formed by stretching and bending in the factory; the side edge of each curved steel plate 20 close to the aluminum panel 10 is a curve consistent with the corresponding position of the hyperbolic surface, and is formed in the factory by laser wire cutting, and the straight edge is opposite to the curved edge, and the other two sides are also straight edges; the straight round steel tube 30 is cut into sections according to size and punched with through holes 31.

[0031] Step 3: Use threaded connectors to assemble the aluminum plate panel 10, the curved steel plate 20, and the straight round steel pipe 30 into a plurality of hyperbolic unit panels 100.

[0032] Each curved unit plate 100 includes a plurality of small rectangular aluminum plate panels 10 connected side by side. As a preferred embodiment, each small rectangular aluminum plate panel 10 has a width of 200 cm and a length of 1800 cm. The size of the curved unit plate 100 after being assembled side by side is 1800×1500 cm. Both ends of all aluminum plate panels are connected to the curved steel plate 20 respectively, and each curved steel plate 20 is connected to a straight round steel pipe 30 along the length direction; and the connection height of the aluminum plate panel on the curved steel plate 20 is adjustable, and the connection position between the curved steel plate and the straight round pipe is adjustable.

[0033] Specifically, it is preferred that each of the aluminum plate panels 10 is a flat aluminum plate with both sides bent inward to form a 90° folded edge 11, and a connecting profile 13 is connected between the folded edges on both sides at both ends of each of the aluminum plate panels 10 by a first bolt 12, and a connecting hole is provided on the upper surface of the connecting profile 13, and one side of an L-shaped angle code 14 is locked in the connecting hole on the upper surface of the connecting profile 13 with an adjustable position by a second bolt 15; the other side of the L-shaped angle code 14 is connected to the curved steel plate 20 by a third bolt 16, and the connecting position is close to the curved edge 21 of the curved steel plate 20; the connecting hole on the L-shaped angle code 14 is a long hole to facilitate the adjustment of the connecting position.

[0034] Since the aluminum plate panel 10 is relatively long and tension needs to be applied in the middle, a connecting profile 13 is also provided in the middle of the aluminum plate panel 10. Similarly, a connecting hole is opened on the upper surface of the connecting profile 13, and one side of an L-shaped angle code 14 is locked in the connecting hole on the upper surface of the connecting profile 13 with a second bolt 15 in an adjustable position; the other side of the L-shaped angle code 14 is connected to the curved steel plate 20 by a third bolt 16, and the connecting position is close to the curved edge 21 of the curved steel plate 20; the connecting hole on the L-shaped angle code 14 is a long hole to facilitate the adjustment of the connecting position.

[0035] A plurality of first U-shaped semi-threaded screws 22 are movably spaced apart outside the straight round steel tube 30, and two screws of each first U-shaped semi-threaded screw 22 pass through the curved steel plate 20 and are fastened by a first nut 23, so that the curved steel plate 20 is connected to the straight round steel tube 30 along the length direction in an adjustable connection position.

[0036] Step 4: transport several hyperbolic unit panels 100 to the decoration site, hoist the hyperbolic unit panels 100 one by one, and install them on the hyperbolic steel grid with threads, and the hoisting position is adjustable. A grid large round tube 201 has been set on the hyperbolic steel grid 200, and the U-shaped part of the second U-shaped semi-threaded screw 32 is used to hold the grid large round tube 201, and the holding position is movable and adjustable. The screw passes through the through hole 31 of the straight round steel tube 30 and is fastened with the second nut 33. When forming the overall hyperbolic surface, the adjacent aluminum panels between the adjacent hyperbolic unit plates 100 need to be coordinated and adjusted, so an adjustable plug-in is used: the L-shaped corner code 14 on one of the aluminum panels extends a plug-in board 141 outward, and the connecting wire profile 13 at the end of the other aluminum panel is connected to a connecting board 17 with a U-shaped plug-in groove, and the plug-in board 141 is plugged into the U-shaped plug-in groove of the connecting board 17 and can slide therein, thereby adjusting the position between the two adjacent aluminum panels. Finally, a large-area hyperbolic aluminum decorative panel is formed.
