Description

Technical Field

[0001] This invention belongs to the field of screen system structure and installation technology, and in particular relates to a large screen system and its construction and installation method. Background Technology

[0002] In the interior design of five-star and ultra-five-star hotels, the lobby is often considered the core area that best reflects the project's level, aesthetic preferences, and brand character. Among these elements, large screens, as one of the most important spatial dividers and visual focal points in the lobby, have extremely high requirements in terms of design, material quality, structural performance, and long-term stability. For large screens exceeding 3 meters in height, their structural stability, resistance to deformation, and installation precision directly affect safety and lifespan.

[0003] In existing technologies, hotels commonly use a screen structure with a "304 stainless steel outer frame + carbon steel inner frame + wood veneer + suspended metal rod + ordinary glass brick inlay" as the main solution. However, when such screens are used in seaside hotels, environmental factors will significantly amplify the weaknesses of traditional structures. The technical problems with existing technologies are: lobby areas are often places with high concentrations of people and strong airflow; vibrations caused by sea breezes entering the room also require screens with higher structural stability, maintaining their appearance without deformation or swaying over long-term use. Traditional solutions can basically meet decorative requirements in ordinary indoor environments, but in seaside projects, due to the limited strength of the frame, sagging is likely to occur in the middle when the height exceeds 3 meters; the metal rods are suspended installations with no fixed connection between the ends and the frame (5-8mm gap), making them prone to swaying after being blown by sea breezes or touched by people, causing vibrations, noise, and even safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a large-scale screen system and its construction and installation method. The technical problem to be solved is that the frame has limited strength and is prone to sagging in the middle when the height exceeds 3m; the metal rods have gaps due to the suspended installation structure, and are prone to swaying when blown by sea winds or touched by people, resulting in vibration noise and even safety hazards.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A large-scale screen system and its construction and installation method, comprising: The outer frame of the screen is a rectangular structure; The first inner frame is fixed to the inside of the outer frame of the screen.

The lower ends of the first connecting rods are respectively connected to both sides of the top of the screen's outer frame. The upper ends of the first connecting rods and the lower ends of the second connecting rods are connected by the outer sleeve and fastening bolts. The upper end of the second connecting rod is fixedly connected to the roof concrete structure. The lower end of the diagonal brace is fixedly connected to the second connecting rod, and the upper end of the diagonal brace is fixedly connected to the roof concrete structure. The bottom fixing device includes a bottom support rod, a transition square steel and a pre-embedded angle bracket. The pre-embedded angle bracket is fixedly connected to the bottom building structure by bottom fixing bolts and is embedded in the bottom concrete layer. The transition square steel is connected to the pre-embedded angle bracket by angle bracket connecting bolts. The bottom support rod is connected between the bottom of the screen's outer frame and the top of the transition square steel.

[0006] The large screen system described above further includes a horizontal connecting rod, which is fixedly connected between two first connecting rods; the height of the screen's outer frame is greater than or equal to 3 meters.

[0007] The large screen system of the present invention, as described above, further includes the following: the first inner frame includes vertical columns and horizontal beams that are perpendicularly fixed to each other on the inner side of the outer frame of the screen, and two adjacent vertical columns and horizontal beams form a rectangular structure; the second inner frame includes horizontal fixing rods and vertical fixing rods that are perpendicularly fixed to each other on the inner side of the outer frame of the screen, and two adjacent vertical fixing rods and horizontal fixing rods form a grid-shaped segmentation structure, the segmentation structure being located within the rectangular structure, and forming four brick installation spaces at the four apex positions of the rectangular structure.

[0008] In the large screen system described above, the second inner frame's horizontal and vertical fixing rods are stainless steel round tubes. Mounting holes for installing the stainless steel round tubes are provided on the inner wall of the outer frame of the screen. The ends of the stainless steel round tubes are inserted into the mounting holes, and the mounting holes are coated with anaerobic anti-corrosion adhesive.

[0009] The large screen system described above further includes an outer frame and a first inner frame made of stainless steel rectangular steel tubes. An aluminum profile is fixed to the outer wall of the rectangular steel tube. The outer surface of the aluminum profile is covered with a wood veneer layer by a hot-pressing composite process. The joints of the wood veneer layer are made at a 45° bevel and sealed with UV weather-resistant adhesive at the bevel joint.

[0010] The large screen system described above further includes a stainless steel baseboard fixedly installed on the outer wall of the bottom support rod.

[0011] The large screen system described above further includes a lamp mounting plate, which is fixed to the lower end of the first connecting rod, and a lighting fixture is installed inside the lamp mounting plate.

[0012] The present invention also provides a construction and installation method for a large screen system, wherein the large screen system is any one of the large screen systems described above; The manufacturing process includes the following steps: the outer frame, the first inner frame, and the second inner frame of the screen are made of 316L stainless steel. They are first pickled and passivated, and then coated with primer and fluorocarbon topcoat respectively; the aluminum profiles are anodized and coated with primer; the outer frame of the screen is welded using argon arc welding, and after welding, it is treated with stainless steel polishing paste and then coated with fluorocarbon topcoat. Factory pre-assembly steps: Step 1: Assemble the frame. The outer frame of the screen is fixed to the first inner frame with bolts, and the verticality is calibrated with a laser line projector. Step 2: Install the decorative surface. The aluminum profile wood veneer assembly is fixed to the outer wall of the outer frame and the first inner frame of the screen. The flatness of the wood veneer surface is checked. Step 3: Assemble the functional components. The horizontal and vertical fixing rods of the second inner frame are inserted into the mounting holes on the inner wall of the outer frame of the screen for fixation. The glass bricks are embedded in the brick installation space and positioned with adhesive strips. The spacing between the horizontal and vertical fixing rods and the offset of the glass bricks are checked to be within the predetermined range. Step 4: Simulate environmental testing. The pre-assembled screen system is placed in a high temperature and high humidity chamber for 72 hours. After checking for no deformation or cracking, it is disassembled into frame modules, decorative modules, and functional component modules and transported. On-site installation steps: Assemble the frame module, decorative module and functional component module separately on the construction site.

[0013] The construction and installation method of the screen system described above, preferably, includes the following on-site installation steps: S1 Positioning: Use a laser line projector to display the installation baseline of the screen's outer frame; S2 Fixing: Connect and install the screen's outer frame using a top fixing device and a bottom fixing device; S3 Surface Module Installation: Fix the surface modules formed by aluminum profiles and wood veneer layers to the outer frame of the screen and the outer wall of the first inner frame according to the pre-assembly markings; S4 Metal Rod Installation: Insert the horizontal and vertical fixing rods of the second inner frame into the installation holes on the inner wall of the screen's outer frame according to their numbers, and reinforce them with anaerobic adhesive; S5 Glass Brick Installation: After the glass bricks are installed into the brick installation space, fill the gap between the glass bricks and the adjacent frame with transparent weather-resistant silicone sealant.

[0014] The construction and installation method of the screen system described above, preferably, includes a finishing step after the S5 glass brick installation step: cleaning, wiping the wood veneer layer, horizontal fixing rods and vertical fixing rods, and glass bricks with a neutral detergent to remove glue residue and dust; anti-corrosion inspection, inspecting the anti-corrosion coating of weld joints and bolt holes, and applying fluorocarbon topcoat to any damaged areas of the anti-corrosion coating.

[0015] The beneficial effects of this invention are: The overall structural stability is significantly improved. Through the coordinated connection of the top fixing device (first connecting rod + second connecting rod + diagonal brace) with the bottom support rod and pre-embedded corner brackets, a two-way fixing system is formed along the force path, effectively preventing the high-positioned screen from swaying and shifting under strong winds and airflow disturbances. The outer frame and the first inner frame are constructed with stainless steel rectangular tubing to form a rigid main body, enhancing the overall bending stiffness and avoiding the problem of sagging in the middle that is common in traditional large-size screens.

[0016] This invention solves the technical problems of limited frame strength, which can easily cause the middle part to sag when the height of the screen exceeds 3m; and the gaps in the metal rod due to the suspended installation structure, which can easily sway when blown by sea wind or touched by people, resulting in vibration, noise, or even safety hazards.

[0030] This invention also provides a construction and installation method for a large-scale screen system, wherein the large-scale screen system is any of the large-scale screen systems described in the above embodiments; I. Manufacturing Steps: The outer frame 10, the first inner frame 40, and the second inner frame 50 of the screen are made of 316L stainless steel. They are first pickled and passivated, then coated with primer and fluorocarbon topcoat respectively. The aluminum profile 12 is anodized and then coated with primer. The outer frame 10 of the screen is welded using argon arc welding, and after welding, it is treated with stainless steel polishing paste and then coated with fluorocarbon topcoat. Through the above methods, the large screen system can adapt to long-term use environments such as coastal areas, high humidity, and public spaces. The multiple anti-corrosion system, including 316L stainless steel, fluorocarbon topcoat, and anaerobic anti-corrosion adhesive, achieves comprehensive rust prevention, reduces the risk of structural fatigue and appearance aging caused by salt spray corrosion, and extends service life.

[0031] II. Factory Pre-assembly Steps: Step 1: Assemble the frame. The outer frame 10 of the screen is fixed to the first inner frame 40 with bolts, and the verticality is calibrated with a laser line projector. Step 2: Install the decorative surface. The aluminum profile 12 and wood veneer layer 13 components are fixed to the outer walls of the outer frame 10 and the first inner frame 40 of the screen. The flatness of the wood veneer surface is checked. Step 3: Assemble the functional components. The horizontal fixing rods 51 and vertical fixing rods 52 of the second inner frame 50 are inserted into the mounting holes on the inner wall of the outer frame 10 of the screen for fixation. The glass bricks 60 are embedded in the brick installation space and positioned with adhesive strips. The spacing between the horizontal fixing rods 51 and the vertical fixing rods 52 and the offset of the glass bricks 60 are checked to be within the predetermined range. Step 4: Simulate environmental testing. The pre-assembled screen system is placed in a high temperature and high humidity chamber for 72 hours. After checking for no deformation or cracking, it is disassembled into frame modules, decorative surface modules, and functional component modules and transported. In one embodiment, the test conditions are 60℃ and 95%RH to simulate the long-term coastal use environment. Modular pre-assembly design shortens the on-site installation cycle and improves construction accuracy. By pre-assembling in the factory and verifying in a simulated environment before disassembly and transportation, on-site installation only requires positioning, assembly, and plug-in, resulting in minimal construction errors and reducing the risks of high-altitude installation.
