Description

Technical Field

[0001] This invention relates to the field of LED screen installation technology, specifically to an installation structure and process for an indoor ski resort LED screen. Background Technology

[0002] With the progress of the times, people are quite satisfied with their basic needs for food, clothing, housing, and transportation, and are becoming increasingly interested in sports and entertainment. Indoor skiing has been a popular activity in recent years. To provide a better entertainment experience for the public, some indoor ski resorts have installed large LED screens for viewing.

[0003] The installation structure of the LED screen needs to pass through the insulation area and be connected and fixed to the main structure of the building. The current installation structure does not have cooling and airtight treatment. After the connectors pass through the insulation board, it causes problems such as poor heat insulation, poor airtightness, and easy condensation, which affects the insulation performance of the ski resort and the service life of the structural components. Summary of the Invention

[0004] The purpose of this invention is to provide an installation structure and process for an indoor ski resort LED screen, aiming to solve the problems of poor heat insulation, poor airtightness, and easy condensation in existing installation structures.

[0005] To address the aforementioned problems in the prior art, the present invention adopts the following technical solution:

[0006] An installation structure for an indoor ski resort LED screen includes an insulated wall and square tubes. The insulated wall is assembled from multiple insulated panels, which are fixed to vertical purlins using fixed angle brackets. Each insulated panel has an opening at a predetermined position.

[0007] The square tube is filled with polyurethane material; an anchoring steel plate is welded to the root of the square tube, and the anchoring steel plate is fixed to the wall structure of the ski resort using chemical anchors; the front end of the square tube passes through the opening and is connected to an adapter, which is used to install an LED screen.

[0008] The opening and the square tube have a gap, and the gap and the side wall of the square tube are uniformly sprayed with polyurethane foam. The outer surface of the polyurethane foam is wrapped with an aluminum alloy protective plate. A galvanized sheet is provided on the inner side of the gap for sealing, and a galvanized sheet is provided on the outer side of the gap. One end of the galvanized sheet on the outer side of the gap is connected to the insulation board, and the other end is connected to the aluminum alloy protective plate.

[0009] Preferably, the galvanized sheet metal part is fixed to the insulation board by rivets; a continuous butyl tape is pasted around the connection between the galvanized sheet metal part and the insulation board; and the connection between the galvanized sheet metal part and the aluminum alloy protective plate is sealed with weather-resistant adhesive.

[0010] Preferably, the square tube has multiple ribs around its root.

[0011] An installation process for an indoor ski resort LED screen installation structure as described above includes: positioning and installation steps for anchoring steel plates and square tubes.

[0012] Measure the elevation and axis position of the wall structure, locate the placement position of the chemical anchors, drill holes to install the chemical anchors and anchoring steel plates; locate the connection position of the square tube on the anchoring steel plate, and weld the square tube;

[0013] Installation steps for insulated walls:

[0014] The location of the opening is determined based on the square tube already installed on site, wherein the size of the opening is 100mm larger than each side of the square tube;

[0015] The insulation boards are installed horizontally by interlocking and vertically by butt joints, starting from the bottom layer; wherein...

[0016] Before installing the upper insulation board, apply sealant to the tongue and groove of the lower insulation board and apply polyurethane foam to the horizontal contact position.

[0017] The upper insulation board is vertically lifted and horizontally moved. When it is on the same plane as the lower insulation board, the upper insulation board is slowly lowered so that it accurately falls on the tongue and groove of the lower insulation board, and the polyurethane foam is squeezed out from the transverse seam between the two insulation boards.

[0018] Weld the fixing brackets of the insulation board to the vertical purlins, and complete the installation of the insulation board in sequence;

[0019] After the insulation board is fixed, the adapter is welded to the end of the square tube;

[0020] The steps for interrupting cooling:

[0021] The gaps around the inside and outside of the opening are sealed with the galvanized sheet metal using rivets, and polyurethane foam is sprayed from the outside of the opening to seal the opening and evenly wrap the square tube, and the polyurethane foam is filled inside the square tube.

[0022] The aluminum alloy protective plate is wrapped with polyester foam around the outer periphery of the square tube;

[0023] Apply sealant to the connection between the galvanized sheet fold and the aluminum alloy protective plate, and arrange butyl tape along the entire length of the connection between the galvanized sheet fold and the insulation plate.

[0024] Preferably, when installing the insulation board corresponding to the square tube, the insulation board is lifted and stopped when its lower edge is 20mm higher than the insulation board below. The insulation board is then moved horizontally towards the square tube so that the holes in the insulation board pass through the square tube.

[0025] Preferably, the step of "applying sealant to the tongue and groove of the insulation board" includes: first applying a layer of self-adhesive to the tongue and groove of the insulation board, and then applying a layer of weather-resistant sealant.

[0026] The advantages of this invention are:

[0027] The installation structure and process for indoor ski resort LED screens provided by this invention solve the problems of poor heat insulation, poor air tightness, and easy condensation in existing installation structures, and improve the sealing and heat insulation performance of the insulation board, thereby extending the service life of the installation structure.

[0030] Figure 3 This is a schematic diagram illustrating the installation process of an insulation board corresponding to a square tube according to the present invention. Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] See appendix Figure 1 , Figure 1 An example is shown illustrating the main structure of an indoor ski resort LED screen installation structure. For example... Figure 1 As shown, the indoor ski resort LED screen installation structure provided in this embodiment includes an insulated wall 1 and a square tube 2. The insulated wall 1 is assembled from multiple insulated panels 3, which are fixed to vertical purlins 5 using fixing brackets 4. An opening 11 is provided at a predetermined position on each insulated panel 3. The insulated panels 3 are located indoors in the ski resort; in other words, they are located on the inner side of the ski resort wall structure 6.

[0033] The square tube 2 is a structural component used to install the LED screen. An anchoring steel plate 7 is welded to the base of the square tube 2, and multiple ribs 8 are provided around the base of the square tube 2 to increase structural strength. The anchoring steel plate 7 is fixed to the wall structure 6 of the ski resort using chemical anchors 9. The front end of the square tube 2 passes through the opening 11 of the insulation board 3 and connects to a connector 10, which is used to install the LED screen. There is a gap between the opening 11 and the square tube 2. The gap and the sidewall of the square tube 2 are uniformly sprayed with polyurethane foam 12, and the outer surface of the polyurethane foam 12 is wrapped with an aluminum alloy protective plate 13. A galvanized sheet folding piece 14 is provided on the inner side of the gap for sealing, and another galvanized sheet folding piece 14 is provided on the outer side of the gap. One end of the galvanized sheet folding piece 14 on the outer side of the gap is connected to the insulation board 3, and the other end is connected to the aluminum alloy protective plate 13. The square tube 2 is filled with polyurethane material.

[0034] The galvanized sheet metal part 14 is fixed to the insulation board 3 by rivets. A continuous length of butyl tape is applied around the connection between the galvanized sheet metal part 14 and the insulation board 3. The connection between the galvanized sheet metal part 14 and the aluminum alloy protective plate 13 is sealed with weather-resistant adhesive 15.

[0035] Based on the above-described indoor ski resort LED screen installation structure, this invention also provides an installation process for the indoor ski resort LED screen installation structure, which mainly includes the following steps:

[0036] Positioning and installation steps for anchoring steel plate 7 and square tube 2:

[0037] First, measure the elevation and axis position of wall structure 6 to determine the placement of chemical anchors 9, ensuring a positional error of no more than 5mm. Drill holes to install the chemical anchors 9 and anchoring steel plates 7. The chemical anchors 9 are φ14*160mm in size, with a hole depth of 125-130mm. Before installing the chemical anchors 9, use an air pump to blow away any ash or debris from the holes. After installation, wait for the anchoring agent to harden according to the time specified in Appendix 1 before installing the anchoring steel plates 7. The dimensions of the anchoring steel plates 7 are 250*250*12mm.

[0038]

[0039] After the anchoring steel plate 7 is installed, the accurate position of the positioning and connecting square tube 2 is measured again, and the connecting square tube 2 is welded. The dimensions of square tube 2 are 120*80*5. Before welding, the bevel is prepared according to the design drawings. After the positioning is correct, the welding operation is carried out. The weld joint must be fully welded to ensure the weld strength. Before the installation of square tube 2, a V-shaped bevel is prepared with a blunt edge thickness of 1-1.5mm. The bevel penetration weld is a secondary weld, and ultrasonic testing is performed on 20% of the weld joints. The four rib plates 8 adopt double-sided bevel penetration welding.

[0040] Installation steps for insulation wall 1:

[0041] The location of the opening 11 is determined based on the already installed square tube 2 on site, where the size of the opening 11 is 100mm larger than each side of the square tube 2. Specifically, after the square tube 2 is installed, the insulation board 3 is installed. The location of the opening 11 of the insulation board 3 is determined based on the already installed square tube 2 on site, where the size of the opening 11 of the insulation board 3 is 100mm larger than each side of the square tube 2. The location of the opening 11 of the insulation board 3 must be accurate. If the hole position is deviated or too small, it will affect the installation of the insulation board 3 and will also prevent the square tube 2 from passing through the insulation board 3 smoothly. If the opening 11 is too large, it will affect the strength and insulation performance of the insulation board 3. Therefore, the location and size of the opening 11 of the insulation board 3 must be accurately determined before construction.

[0042] Insulation boards 3 are installed horizontally by interlocking and vertically by butt joints, starting from the bottom layer; among them, insulation wall 1 uses rock wool insulation boards 3, with a thickness of 240mm and a density of 135kg / m³. 3 The length is 5-9 meters, and the height is 1000 mm. When installing the insulation board 3 corresponding to the position of the square tube 2, two coats of white sealant should be applied to the tongue-and-groove groove of the lower insulation board 3 before installation. Figure 2 As shown, first apply the self-adhesive 16 and then the weather-resistant sealant 15 (the sealant should be applied to the corner of the tongue and groove of the insulation board 3). The sealant applied to the tongue and groove should have a certain height and should be dense, continuous and uniform. At the contact position of the rock wool in the horizontal seam between the upper and lower insulation boards 3, first apply polyurethane foam 12 to foam it. After the application is completed, vertically lift the insulation board 3 to be installed. When the lower edge of the installed insulation board 3 is 20mm higher than the lower insulation board 3, stop lifting and move it horizontally inward towards the square tube 2 so that the square tube 2 passes through the reserved opening 11 of the insulation board 3. When it is on the same plane as the lower insulation board 3, stop moving and slowly lower the insulation board 3, accurately placing it on the tongue and groove of the lower insulation board 3. Squeeze the polyurethane foam 12 from the horizontal seam between the insulation boards 3 to ensure that the foam is dense. Weld the corner bracket 4 of the insulation board 3 to fix the insulation board 3 to the vertical purlin 5. Complete the installation of each insulation board in sequence. The installation process for the insulation boards is as follows: Figure 3 As shown. After the insulation board 3 is fixed, the LED screen adapter 10 can be welded to the end of the square tube 2 according to the drawing requirements.

[0043] The steps for interrupting cooling:

[0044] After all the insulation boards 3 are installed, the seams around the openings 11 on both sides of the insulation boards 3 are sealed with galvanized sheet metal fittings 14 using rivets. Before fixing with rivets, butyl tape is applied along the entire length of the junction between the galvanized sheet metal fittings 14 and the insulation boards 3, and weather-resistant adhesive 15 is applied around the galvanized sheet metal fittings 14 before rivet fixing. Foam is used to seal the openings 11 through the pre-drilled holes in the galvanized sheet metal fittings 14 on the outside of the insulation boards 3, ensuring the foam is dense. Simultaneously, polyurethane foam 12 is uniformly sprayed onto the outer wall of the square tube 2 to form an insulation layer. The insulation layer thickness is not less than 50mm, and the insulation layer is continuous and of uniform thickness. The interior of the square tube 2 is filled with polyurethane foam 12. In this embodiment, B1 grade polyester foam is used for the outer wall of the square tube 2. Then, an aluminum alloy protective plate 13 is wrapped around the outer periphery of the polyester foam surrounding the square tube 2. Apply sealant (weatherproof sealant 15) to the joint between the galvanized sheet fold 14 and the aluminum alloy protective plate 13.

[0045] It should be noted that airtightness has a significant impact on the performance of insulation board 3. The airtightness construction around the perimeter of the square tube 2 after it passes through insulation board 3 is crucial. Airtightness at this location is mainly ensured by butyl tape and weather-resistant sealant. The sealant and weather-resistant sealant 15 must be applied continuously, with sufficient overlap to ensure a tight, airtight joint. The inner side of insulation board 3 is the interior of the ski resort, a cold zone; the outer side of insulation board 3 is one side of the wall structure 6, a warm zone.

[0046] In summary, the indoor ski resort LED screen installation structure and installation process provided by this embodiment of the invention connect the square tube 2 to the wall structure 6 in a primary structure. After the square tube 2 passes through the insulation board 3 into the cold zone, it is welded to the LED screen adapter 10. The construction process incorporates cold treatment and airtightness treatment, thereby solving the problems of poor heat insulation, poor airtightness, and easy condensation in existing installation structures, improving the sealing and heat insulation performance of the insulation board 3, and thus extending the service life of the installation structure.

For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
