Description

Technical Field

[0001] This invention belongs to the field of building facade renovation, specifically a combined glass composite lighting irregular curtain wall system and its construction method. Background Technology

[0002] Building facade renovation is an important part of urban renewal, but traditional solutions for redesigning and modifying the curtain wall structure of the facade have the following problems: First, the renovation process often requires the demolition of the original exterior wall enclosure structure, which not only causes significant construction disruption and takes a long time, but may also affect the safety of the main building structure. Second, the integration of facade lighting and decoration is low. Traditional lighting facilities such as large flat LED screens, light strips, and wall washer lights are often used to meet the floodlighting needs of the facade. This lighting design and installation method often appears superficial and lacks innovation. It has the problems of monotonous appearance and insufficient artistic expression. Moreover, the existing LED screens are only effective at night and require a large number of spotlights, which cannot take into account the visual effect under natural light. Third, traditional curtain wall materials (such as flat glass) increase the load on the original building's exterior walls, which is not conducive to the control of the original building's load. At the same time, they are expensive and have poor economic efficiency. Fourth, the construction process is crude, such as repeated scaffolding erection and a high proportion of on-site component processing, which leads to extended construction period and increased costs.

[0003] To address the aforementioned issues, there is an urgent need for a technology that balances structural safety, adaptability to renovation, economy, and artistic expression in the renovation of existing building facades. This technology should integrate decoration and lighting without damaging the original building envelope, while optimizing construction processes and improving renovation efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a combined glass composite lighting irregular curtain wall system and construction method to solve the technical problems of large disturbance and low safety, low integration of facade lighting and decoration, heavy curtain wall material and high cost, and rough construction process in the existing exterior curtain wall structure renovation construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite glass lighting irregular curtain wall system includes: The steel structure framework rests on the ground, with the number of stories corresponding to the original building. The horizontal projection of the steel structure framework on the same floor forms an irregular wall line with alternating concave and convex sections. The horizontal projection lengths and floor heights of adjacent vertical steel structure frameworks are different. Each layer of the steel structure framework includes a main frame and an installation frame. The main frame is fixedly connected to the outside of the original building structure, and the installation frame extends outward relative to the main frame. The modular glass panels are assembled in sections, side by side. They are enclosed on the outside of the steel structure frame of each layer by interlocking slots located at the outer end of the mounting frame and arranged adaptively along the irregular city wall line. They are formed by the parallel connection of vertical strip-shaped glass units with a channel-shaped cross-section. The interlayer space between the modular glass panels and the main frame forms the lighting installation space for each layer. The composite lighting installation is a modular, parallel assembly that can be adapted to the lighting installation spaces on each floor and placed on the mounting frame at the bottom of each floor. Each assembly unit includes a frame, a lighting fixture, and a diffused light tensile membrane. The frame is rectangular in shape and is set along the outer surface of the main frame and fixedly connected to it. It includes a rear frame for the lighting fixture and a front frame for the membrane fixture, which are set parallel to each other. The rear frame for the lighting fixture and the front frame for the membrane fixture are connected as one unit on both sides by inter-frame tie beams. The lighting fixture is fixedly connected to the front side of the rear frame for the lighting fixture. The diffused light tensile membrane is laid flat and fixedly connected to the front side of the front frame for the membrane fixture, so that the diffused light tensile membrane hangs over the outside of the lighting fixture and maintains a distance from the lighting fixture. The curtain wall sealing panel is set on the outside of the combined glass panel to seal the stepped surfaces formed by the different lengths of the horizontal projection of the steel structure frame of the adjacent vertical layers. Together with the steel structure frame of each layer and the combined glass panel, it forms a box-shaped curtain wall of different sizes and depths on each layer.

[0006] The main frame includes vertical and horizontal keels. The vertical keels include full-height inner keels that are fixedly connected to the pre-embedded steel components of the original building, and floor-height outer keels corresponding to the layer positions of the steel structure frame. The horizontal keels are fixedly connected between adjacent full-height inner keels, adjacent floor-height outer keels, and between corresponding full-height inner keels and floor-height outer keels. Diagonal keels are also provided at the diagonal positions within the keel frame enclosed by the horizontal and vertical keels. The lighting fixture installation space is located on the outside of the outer keel of the floor height, and the rear frame of the lighting fixture is fixedly connected to the outside of the main frame.

[0007] The installation frame includes horizontal cantilever beams arranged in groups at intervals along the top and bottom of each layer of steel structure skeleton, with the inner end of each group of horizontal cantilever beams fixedly connected to the outer side of the main frame of the corresponding layer. The outer ends of each horizontal cantilever beam are connected together by horizontal connecting end beams. Each group of horizontal cantilever beams is fixedly connected to the outer side of a support member arranged vertically, and each support member is fixedly connected to an insertion slot for a combined glass panel arranged vertically.

[0008] The supporting component is an angle steel, including a connecting leg and a supporting leg. The connecting leg is tightly attached to and fixedly connected to the horizontal cantilever beam. The insertion groove includes a groove bottom plate and a groove side plate. Each groove bottom plate is padded with an elastic pad and fixedly connected to the corresponding supporting leg. The thickness of each combined glass panel is less than the width of the corresponding interlocking groove of each layer, the height of the combined glass panel is less than the height between the bottom plates of the corresponding interlocking groove of each layer, an elastic pad is placed between each combined glass panel and the bottom plate of the corresponding layer, each combined glass panel is bonded to the outer side plate of the groove at the corresponding installation position with double-sided adhesive, and the joint between each combined glass panel and the outer side plate of the groove is sealed with weather-resistant sealant.

[0009] The assembly section of the composite glass panel includes straight sections, as well as hot-bending sections located at both ends of the protrusion and on both sides of the splicing straight sections; The opening of the glass unit faces the original building. The glass unit includes a unit base plate and unit side plates on both sides. A transition section is formed between the unit base plate and the unit side plates. The gap between the transition sections of adjacent glass units is sealed with weather-resistant sealant.

[0010] The rear frame of the lamp includes a first frame, within which a set of vertical rods of full height and a set of parallel horizontal rooting rods are provided. The lamp is a point light source emitting strip, which is set and fixedly connected to the outside of the corresponding horizontal rooting rod. Each point light source emitting strip includes a row of connected point light source modules, and each point light source module includes a set of symmetrically arranged point light sources. The front frame of the luminaire includes a second frame. Each assembly unit's frame also includes a device reinforcement frame added to the back side. The width of the device reinforcement frame is adapted to the width of the corresponding device frame. It includes reinforcing uprights respectively set on the back side of the first frame corresponding to the two sides of the first frame. The reinforcing uprights are connected to the corresponding first frame by horizontal inter-bar tie beams. The device reinforcement frame also includes a set of reinforcing horizontal bars connecting the reinforcing uprights in the unit. The device reinforcement frame is fixedly connected to the outside of the main frame.

[0011] The pre-embedded connecting steel components are installed on the end beams of the original building's floor slab. These include rooting panels installed on the outer surface of the end beams. The rooting panels are fixed by rear-expanded anchor bolts anchored into the end beams, or by rooting back plates that cooperate on the back side and tie bolts that penetrate the end beams. The pre-embedded connecting steel components also include channel steel adapters that are vertically fixed to the outer side of the rooting panels and are symmetrically arranged on the left and right. The channel steel adapters are clamped on both sides of the inner keel with their openings facing outwards, and are fastened by connecting bolts that penetrate the inner keel on the left and right.

[0012] The curtain wall panel is made of aluminum single panel. Each end of the curtain wall panel is provided with a panel connector facing the original building. The panel connector is connected to the support, interlocking groove and panel support near the end position of the combined glass panel. The panel support is fixedly cantilevered on the outside of the support. The gap between the curtain wall panel and the support, interlocking groove and panel support is sealed with foam rod and weather-resistant sealant.

[0013] A construction method for a combined glass and lighting irregular curtain wall system, the construction steps are as follows: S1. Pre-construction preparation: BIM modeling is used in conjunction with a total station to perform three-dimensional positioning of the original building facade, lay out the curtain wall grid, and mark and fix the points. Then, the dimensions and installation coordinates of each component of the pre-embedded connecting steel components, steel structure frame, combined glass panels, composite lighting devices and curtain wall sealing panels are exported. The installation coordinates of each component are numbered. According to the box-type curtain wall, each component is divided into installation units according to each layer, concave and convex parts. The assembly units of each component are pre-processed in the factory according to the exported dimensions and transported to the construction site. Among them, according to the lighting requirements, the number of point light source modules on each point light source light strip and the number of point light sources on each point light source module are pre-designed. S2, retain the original enclosure structure on the front side of the original building; The construction was carried out using a combination of aerial work platforms and truck cranes. S3, Installation of pre-embedded connecting steel components: Based on the installation coordinates of the pre-embedded connecting steel components obtained in S1, holes are drilled in the original building for construction. S4, Steel Structure Frame Installation: According to the design drawings, the steel structure frame is divided into assembly units according to each layer, concave and convex parts, and construction is carried out using double cranes in conjunction with a straight boom truck; the installation follows the principle of symmetrical installation from bottom to top and from both sides to the middle; the main frame installation sequence is vertical keel, diagonal keel and horizontal keel, and the inner keel of the full height is close to the original enclosure structure when it is constructed; then the frame is installed on the outside of the main frame, and the construction sequence is horizontal cantilever beam and horizontal connecting end beam; S5, Installation of combined glass panels: S51, Installing the plug-in groove: The support is pre-connected to the steel structure frame, and the plug-in groove is installed on the support; the plug-in groove is a channel steel with hot-dip galvanized surface, and an elastic pad is laid at the bottom of the plug-in groove. S52, the combined glass panels are constructed in assembly sections, one assembly section at a time. Glass units are inserted into the insertion slots 50 of each installation unit in sequence, and then the assembly sections are connected. S53, Sealed composite glass panel, the joints between the interlocking groove and the composite glass panel, between glass units, and between the interlocking groove and the original building are all sealed with weather-resistant sealant. S6, Installation of composite lighting fixtures: S61, place the frame of each assembly unit on the horizontal cantilever beam at the bottom of each floor in sequence, and then fix the back frame of the lamp to the outer keel, horizontal keel or diagonal keel of the main frame. S62, tighten and fix the edges of two adjacent assembly units together; S7, Curtain wall panel installation: Foam rods are filled at the joints of each curtain wall panel and the joints between panels, and weather-resistant sealant is injected for sealing. S8, Lighting Adjustment: Based on the design load requirements, set the number of transformers, switches, and sub-controllers, and ensure that the actual load does not exceed 80% of the rated load; transformers, switches, and lighting fixtures are connected in parallel, and sub-controllers are connected in series, using multi-level control and zone control methods.

[0014] When the device frame has a device reinforcement frame on the back side, during construction S61, the device reinforcement frame is fixedly connected to the outer keel of the main frame, the horizontal keel or the diagonal keel. During construction S62, two adjacent device reinforcement frames are also tightened and fixedly connected.

[0015] Compared with the prior art, the present invention has the following features and beneficial effects: I. This invention retains the original enclosure structure and constructs on the outside of the enclosure structure, thus avoiding damage to the main building structure during the renovation process and reducing the potential impact of construction on building safety.

[0016] II. This invention integrates a steel structure frame, combined glass panels, and composite lighting devices into one unit, successfully solving problems such as the combination of external wall load-bearing capacity and composite lighting devices, as well as the installation of large decorative curtain walls. The irregular design of the steel structure frame, together with the combined glass panels and composite lighting devices, forms an irregularly arranged irregularly shaped curtain wall, resulting in more diverse designs.

[0017] The steel frame provides the main mechanical support, while the combined glass panels serve as decoration and enclosure. The irregular design of the steel frame, combined with the combined glass panels and integrated lighting fixtures, creates irregularly arranged, uniquely shaped curtain walls, resulting in a more diverse aesthetic.

[0018] III. The composite lighting device of this invention comprises an installation module consisting of a device frame, point light source modules, and a diffused light tensile membrane. The device frame is connected to a steel structure frame, providing a foundation for the point light source modules and the diffused light tensile membrane. The surface layer of the diffused light tensile membrane effectively shields the LED beads, possesses sufficient strength, and remains undeformed and colorfast under tension. This invention integrates the lighting system with the curtain wall structure, providing illumination at night. During the day, light passes through the combined glass and, combined with the reflective effect of the diffused light tensile membrane, presents a clear view of the membrane material's color, saving electricity and achieving dual day and night visual performance. This invention breaks the limitation of traditional LED screens that are only effective at night, achieving excellent visual effects while being more cost-effective than solutions using numerous spotlights.

[0019] The existing light box has a relatively short distance between the light source and the surface curtain. This invention redesigns the device frame based on actual construction conditions. On the one hand, it provides strength for the connection with the steel structure frame. On the other hand, it precisely controls the distance between the light source and the tensile membrane to 150mm-250mm. The length of the horizontal cantilever beam controls the distance between the tensile membrane and the combined glass panel to 300mm-500mm. The controlled distance is designed in conjunction with the number of point light source modules per square meter to ensure the effect of nighttime illumination and daytime diffused illumination.

[0020] Fourth, this invention optimizes the glass panel and structural system. Existing glass panels are typically segmented by vertically splicing short strips to form longer strips, creating horizontal back ribs at the splicing points. This can easily align with the point light source of the composite lighting device, obstructing light transmission. This invention, based on actual construction conditions, uses vertically continuous channel-shaped glass units arranged horizontally in parallel, resulting in a stable structure. The segmented splicing points do not form vertical back ribs, replacing traditional flat glass, reducing the cost per square meter of material and lightening the overall weight of the curtain wall system.

[0021] Fifth, all components of this invention are assembled from standard unit parts. The unit parts are standardized and processed in the factory and assembled on site. No scaffolding is required during construction. The unit parts are constructed directly using a double crane and a straight boom truck. The composite lighting device is standardized and manufactured in the factory and installed on site, which greatly improves construction efficiency, shortens the construction period, and controls costs.
