Description

Technical Field

[0001] This invention relates to the field of lighting decoration technology for irregular building facades, and specifically to a method for laying out and installing point light source troughs for spherical building glass curtain walls. Background Technology

[0002] A spherical building is simply a structure resembling a sphere. The formation of domed buildings is based on the strongest geometric principle of triangles, with intersecting triangles forming a sphere in a 3:8 or 5:8 ratio. Because of this triangular arrangement, it does not rely on typically thick brick or reinforced concrete walls, nor does it require any internal structural support, thus possessing the largest possible interior space and unobstructed natural light. Spherical buildings, combined with glass curtain walls, achieve excellent lighting and visual effects. These iconic buildings are often equipped with lighting systems to provide a superior sensory experience. However, for spherical buildings, how to install a lighting system and ensure its even distribution remains a major challenge for engineers.

[0003] Therefore, developing a method for laying and installing lighting systems on spherical building glass curtain walls is of great practical significance. Summary of the Invention

[0004] Due to the aforementioned deficiencies in existing technologies, this invention provides a method for laying out and installing a lighting system for a spherical building glass curtain wall. Specifically, it is a method for laying out and installing point light source troughs for spherical building glass curtain walls. This method enables precise cutting and production of point light source troughs on the exterior facade of irregularly shaped spherical buildings, greatly reducing on-site workload and improving overall work efficiency. At the same time, the point light source layout is aesthetically pleasing, and the troughs fit perfectly with the aluminum profiles of the curtain wall. After installation, the troughs are flush with the outer surface of the aluminum alloy profile frame of the glass curtain wall, achieving a smooth spherical surface and beautifying the building facade.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for laying out and installing point light source troughs in spherical architectural glass curtain walls includes the following steps:

[0007] (1) A spherical building glass curtain wall model is constructed using BIM technology, wherein the spherical building glass curtain wall includes a component-type glass curtain wall section and a unit-type curtain wall section;

[0008] (2) Analyze the component-type glass curtain wall section and the unit-type curtain wall section of the spherical building glass curtain wall respectively, and extract the design data of the glass panel of the component-type glass curtain wall section and the unit panel of the unit-type curtain wall section. The unit panel includes a rhombus-shaped glass panel and two triangular glass panels located on both sides of the rhombus-shaped glass panel.

[0009] (3) The light troughs for the external facade are produced according to the dimensions of the glass curtain wall profiles at a 1:1 ratio. The light trough cover is designed in detail to determine the position of the light source and the light trough cover is produced.

[0010] (4) Install on the exterior facade of the spherical building, use bolts to fix the light trough of the exterior facade to the profile of the glass curtain wall, and cover the light trough with the cover.

[0011] The present invention relates to a method for laying out and installing point light source troughs for spherical building glass curtain walls. The method features a rationally designed sequence, enabling precise laying out of the light troughs on the exterior facade of irregularly shaped spherical buildings. This solves the problem of producing light troughs for irregularly shaped spherical buildings and avoids reduced construction efficiency due to on-site cutting caused by dimensional deviations. The method also allows for the pre-arrangement of point light sources, resulting in a more orderly and neat arrangement. The point light sources are evenly distributed on the surface of the spherical building, enhancing aesthetics and overall lighting effects, thus demonstrating promising application prospects.

[0012] As a preferred technical solution:

[0013] As described above, the method for laying out and installing point light troughs for spherical building glass curtain walls, step (2) specifically involves using the parametric analysis method of Rhino+Grasshopper to analyze and extract design data.

[0014] The above-described method for laying out and installing point light source troughs for spherical architectural glass curtain walls includes design data such as panel dimensions, keel tilt angle, surface material tilt angle, keel twist angle, and glass twist angle.

[0015] As described above, the method for laying out and installing point light source troughs in a spherical architectural glass curtain wall, wherein the detailed design refers to ensuring that the point light sources are equidistantly embedded in the trough cover.

[0016] The above-described method for laying out and installing point light source troughs for spherical architectural glass curtain walls involves the production of the external facade point light source troughs and trough covers in a prefabrication plant.

[0017] The above-described method for laying out and installing point light source troughs in a spherical architectural glass curtain wall involves fixing the trough cover to the point light source trough on the exterior facade using snap-fit ​​mechanisms.

[0018] As described above, the layout and installation method of a point light source trough for a spherical architectural glass curtain wall is described in which the power lines and signal lines of the point light source are laid in the point light source trough on the exterior facade and are restricted by the trough cover within the point light source trough on the exterior facade.

[0019] The above-described method for laying out and installing point light source troughs in spherical architectural glass curtain walls further includes:

[0020] (5) After installation, the light source is coded and adjusted to achieve the designed lighting effect.

[0021] The above technical solution is only one feasible technical solution of the present invention. The scope of protection of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0022] The above invention has the following advantages or beneficial effects:

[0033] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0034] Example 1

[0035] A method for laying out and installing point light source troughs in spherical architectural glass curtain walls has been applied to the exterior facade of the Sun Hotel in the Nanxun Ancient Town Tourism Service Supporting Improvement Project (Phase I) undertaken by the applicant. Floors 1-3 of the Sun Hotel facade consist of a modular glass curtain wall system, floors 4-18 primarily consist of a unitized curtain wall system, and floors 19 to the dome are mainly composed of a skylight with modular glass curtain walls, consisting of triangular and rhomboid glass, totaling approximately 30,000 m². 2 The project involves a large workload, employing approximately 340,000 sets of LED point light sources and 28,500m² of light troughs. Due to the large quantity and the irregular spherical shape of the building facade, the layout was challenging. Therefore, this method was adopted, and the specific method is as follows:

[0036] (1) Based on the requirements of the building facade effect, a theoretical model of the glass curtain wall is generated using BIM modeling, as shown in the figure. Figure 1 As shown, the spherical building glass curtain wall includes component-type glass curtain wall sections (floors 1-3, floor 19 to the dome) and unitized curtain wall sections (floors 4-18).

[0037] (2) The unit panel consists of a rhombus and two triangular glass pieces. It is analyzed by decomposing it using a model, such as... Figure 2 As shown, parametric analysis using Rhino+Grasshopper was employed to model and analyze the curtain wall, extracting relevant data such as panel dimensions, keel tilt angle, face material tilt angle, keel torsion angle, and glass torsion angle. This data formed the unitized curtain wall design data, with unit panels as follows: Figure 3 As shown in Table 1 below;

[0038] Table 1 (Data on glass panels for unitized curtain walls)

[0039]

[0040] (3) Similarly, the dome-shaped component curtain wall is analyzed and the relevant design data of the glass panels (dimensions, keel tilt angle, face material tilt angle, keel torsion angle, glass torsion angle) are extracted, such as Figure 4 As shown;

[0041] (4) The exterior facade point light source troughs are produced in the prefabrication plant according to the glass curtain wall profile dimensions at a 1:1 scale. The trough cover is designed in detail (ensuring that the point light sources 5 are equidistantly embedded in the trough cover 4) to determine the position of the point light sources. The trough cover is then produced in the prefabrication plant. Figure 5 As shown;

[0042] (5) Installation is carried out on the exterior facade of the spherical building (using aerial spiders and mechanical vehicles to complete the installation in sequence), specifically: the exterior facade point light source trough 3 is fixed to the glass curtain wall profile 1 using bolts 2, and the trough cover 4 is fixed to the exterior facade point light source trough 3 by clips 8. The power line 6 and signal line 7 of the point light source are laid inside the exterior facade point light source trough 3 and are restricted inside the exterior facade point light source trough 3 by the trough cover 4, such as Figure 6 As shown, after installation, the entire system is coded and debugged to achieve the designed lighting effects.

[0043] The above methods are effective, improving construction efficiency, reducing construction costs, saving construction time, and enhancing the lighting effect on the facade.

[0044] Verification has shown that the spherical building glass curtain wall point light source trough layout and installation method of the present invention has a reasonable step sequence design, realizes accurate layout of the spherical irregular building facade light trough, solves the problem of layout and production of spherical irregular building facade light trough, and avoids the reduction of construction efficiency due to on-site cutting due to dimensional deviation during construction; the point light source is arranged in advance, so that the point light source is arranged more orderly and neatly, the point light source is evenly distributed on the surface of the spherical building, the aesthetics are high, and the overall lighting effect is more beautiful, with good application prospects.
