Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and more specifically, to a large facade unit curtain wall for public buildings. Background Technology

[0002] Large-facade unitized curtain walls are curtain wall systems composed of many independent units. All panels within each individual unit are prefabricated and assembled in the factory, and then transported to the construction site for hoisting according to the project installation sequence.

[0003] Existing unitized curtain walls are often used in public buildings that are typically large in size and located in complex environments. They need to withstand various external forces, such as wind and earthquake forces. When they are installed in large quantities, there is inevitably a certain distance between the fixed structures of each assembled curtain wall unit, making each unit relatively independent to a certain extent. When external forces such as wind are applied, these forces will act directly on the installation structure of a single unit. Since there is no effective connection to distribute the load, the load will be concentrated on the fixed structure of the unit, which can easily lead to excessive load and damage.

[0004] Therefore, a large-facade unitized curtain wall for public buildings is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a large-facade unit curtain wall for public buildings to solve the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 4 The large-facade unitized curtain wall shown includes a left connecting steel frame 1, a right mounting steel frame 2, a reinforcing connecting block 4, and a limiting frame 8. The right mounting steel frame 2 is located on the right side of the left connecting steel frame 1. Connecting plates 3 are provided at the upper and lower ends of the opposite faces of the left connecting steel frame 1 and the right mounting steel frame 2. The reinforcing connecting block 4 is welded to the upper and lower ends of the front end face of the left connecting steel frame 1. A connecting hole 5 is opened in the inner cavity of the end of the reinforcing connecting block 4 away from the left connecting steel frame 1. Mounting holes 6 are opened at the upper and lower ends of the front end face of the right mounting steel frame 2. A curtain wall unit 7 is provided on the rear end face of the connecting plate 3.

[0024] Limiting frames 8 are provided on the upper and lower sides of the front face of the curtain wall unit 7. There are four sets of limiting frames 8. A transverse connecting rod 9 is welded to the opposite face of every two sets of limiting frames 8. Hexagonal bolts 10 are provided in the inner cavity at both ends of the transverse connecting rod 9. Limiting grooves 11 are provided on the rear end faces of the left connecting steel frame 1 and the right mounting steel frame 2. Protrusions 12 are provided on both sides of the front face of the curtain wall unit 7. A vertical support rod is provided in the middle of the transverse connecting rod 9, and the vertical support rod is connected to the back of the curtain wall unit 7 by a buckle.

[0025] Among them, the left connecting steel frame 1 and the right mounting steel frame 2 provide basic support for the entire curtain wall structure, bearing the curtain wall unit 7 and various loads acting on the curtain wall, ensuring the stability and safety of the curtain wall. The connecting plate 3 connects the left connecting steel frame 1 and the right mounting steel frame 2 to each other for reinforcement, enhancing the connection strength between the two, making the entire frame structure more stable, and improving the overall integrity of the curtain wall structure. The reinforcing connecting block 4 is welded to the left connecting steel frame 1, and its connecting hole 5 is set to facilitate the matching with the mounting hole 6 on the right mounting steel frame 2 of the adjacent unit curtain wall through bolts and other connecting parts, realizing the reinforced connection of the adjacent left connecting steel frame 1 and right mounting steel frame 2, making the entire steel frame structure form a more stable whole, effectively resisting various external forces. The curtain wall unit 7 is the main component to realize the building envelope function, with multiple functions such as heat insulation, sound insulation, waterproofing and lighting, which can provide a comfortable indoor environment for public buildings, while meeting the building's appearance design requirements and enhancing the overall aesthetics of the building.

[0026] The limiting frame 8 serves to limit the position of the curtain wall unit 7, ensuring that the curtain wall unit 7 remains in the correct position during installation and use, preventing displacement or shaking, and guaranteeing the overall stability and sealing of the curtain wall. Every two sets of limiting frames 8 are connected by a transverse connecting rod 9 to form a limiting structure, further enhancing the limiting effect on the curtain wall unit 7. Simply insert the curtain wall unit 7 directly between the left connecting steel frame 1 and the right mounting steel frame 2, and slide it downwards. This allows the upper and lower ends of the curtain wall unit 7 to be installed and limited on the outer surface of the connecting plate 3 via the transverse connecting rod 9. Hex bolts 10 are used to connect the limiting frame 8 and the transverse connecting rod 9, ensuring the stability and safety of the entire curtain wall structure. The limiting groove 11 cooperates with the protrusions 12 on both sides of the front face of the curtain wall unit 7 to further limit and position the curtain wall unit 7, ensuring that the curtain wall unit 7 can be accurately installed in the predetermined position, improving installation accuracy, and also limiting the lateral displacement of the curtain wall unit 7 during use, thus ensuring the stability of the curtain wall.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the left connecting steel frame 1 and the right mounting steel frame 2 are symmetrically arranged, and the left connecting steel frame 1 is connected to the right mounting steel frame 2 through two sets of connecting plates 3. Furthermore, the symmetrical arrangement of the left connecting steel frame 1 and the right mounting steel frame 2 can make the stress on the curtain wall structure more uniform. This connection method makes the left connecting steel frame 1 and the right mounting steel frame 2 form an integral frame structure. When the curtain wall is subjected to external forces, the left and right steel frames can work together to resist the external forces, thereby improving the integrity and rigidity of the entire structure.

[0030] In a preferred embodiment, the diameters of the connecting hole 5 and the mounting hole 6 are equal, and the connecting hole 5 and the mounting hole 6 are symmetrically arranged. Furthermore, the fact that the diameters of the connecting hole 5 and the mounting hole 6 are equal facilitates the use of bolts of the same specification to connect and fix the reinforcing connecting block 4 on the left connecting steel frame 1 and the right mounting steel frame 2, thereby achieving the reinforcement effect of adjacent units.

[0031] In a preferred embodiment, the two sets of transverse connecting rods 9 are respectively embedded in the outer surface of the transverse connecting rod 9 to achieve positioning. The hexagonal bolts 10 penetrate the inner cavity of the transverse connecting rod 9 and engage with the inner cavity of the transverse connecting rod 9 to achieve fixation. Furthermore, the two sets of transverse connecting rods 9 are embedded in the outer surface of the limiting frame 8 to achieve positioning, accurately defining the position of the transverse connecting rods 9, ensuring their installation accuracy, and making the entire limiting structure more stable and reliable. The hexagonal bolts 10 penetrate the inner cavity of the transverse connecting rod 9 and engage with the inner cavity of the limiting frame 8 to achieve fixation, which can provide a strong connection force, so that the transverse connecting rods 9 and the limiting frame 8 are tightly connected together, can withstand greater external forces, and are not prone to loosening or falling off.

[0032] In a preferred embodiment, when the curtain wall unit 7 is installed on the front end face of the horizontal connecting rod 9, the two sets of protrusions 12 are respectively embedded into the inner cavities of the two sets of limiting grooves 11 to achieve limiting; furthermore, the cooperation between the protrusions 12 and the limiting grooves 11 can accurately limit the position of the curtain wall unit 7, ensure its installation accuracy, and quickly position it, so that the curtain wall unit 7 is in an accurate position in the entire facade unit curtain wall, ensuring the overall flatness and verticality of the curtain wall, which is conducive to improving the appearance quality of the curtain wall.

[0033] In a preferred embodiment, buffer pads 13 are provided at the edges of both sets of protrusions 12, and supports 14 are provided on the upper and lower ends of the left connecting steel frame 1 and the right mounting steel frame 2. The buffer pads 13 are made of silicone rubber, with a thickness of 5-8mm, and continuously cover the entire length of the protrusions 12. Furthermore, when the curtain wall is subjected to external forces such as wind, earthquakes, or other vibrations, the buffer pads 13 can absorb and buffer the impact force between the protrusions 12 and the limiting grooves 11, reducing hard collisions between components, thereby protecting the curtain wall unit 7, the left connecting steel frame 1, and the right mounting steel frame 2, etc. The components are not damaged by vibration, extending the service life of the curtain wall. During installation, the support 14 can serve as a reference point for positioning and fixing, making it convenient for construction personnel to accurately install the steel frame into the predetermined position. It is also convenient to disassemble and move the steel frame during later maintenance or replacement of curtain wall components. Preferably, the reinforcing connecting block 4 is bolted to the left connecting steel frame 1 through the waist-shaped hole. The length direction of the waist-shaped hole is perpendicular to the plane of the curtain wall unit 7. The inner wall of the limiting groove 11 is provided with EPDM rubber pads with a pad thickness of 3-5mm. A 3mm expansion gap is reserved between the convex strip 12 and the limiting groove 11.

[0034] The working process of this utility model is as follows: First, since the left connecting steel frame 1 and the right mounting steel frame 2 are symmetrically arranged and interconnected by two sets of connecting plates 3, they form an integral frame structure. Supports 14 are used as positioning and fixing reference points to ensure the steel frame is accurately installed in the predetermined position. The curtain wall unit 7 is then inserted between the left connecting steel frame 1 and the right mounting steel frame 2, with its upper and lower ends mounted on the outer surface of the connecting plate 3 via transverse connecting rods 9 for installation limitation. During this process, the protrusions 12 on both sides of the front face of the curtain wall unit 7 are embedded into the left connecting steel frame 1. The limiter 11 on the rear end face of the right mounting steel frame 2 is used for further limiting and positioning to ensure that the curtain wall unit 7 can be accurately installed in the predetermined position and improve the installation accuracy. Every two sets of limiter frames 8 are connected by transverse connecting rods 9 to form a limiter structure. During installation, the two sets of transverse connecting rods 9 are respectively embedded into the outer surface of the limiter frame 8 to achieve limiting and accurately define the position of the transverse connecting rods 9. Then, hexagonal bolts 10 are used to penetrate the inner cavity of the transverse connecting rods 9 and engage with the inner cavity of the limiter frame 8 to fix them, thereby firmly restricting the curtain wall unit 7 within the frame.

[0035] Subsequently, during mass installation, each group of adjacent left connecting steel frames 1 and right mounting steel frames 2 are connected and reinforced through reinforcing connecting blocks 4 and mounting holes 6. The reinforcing connecting blocks 4 are welded to the front end face of the left connecting steel frame 1, and their connecting holes 5 are equal in diameter and symmetrically arranged with the mounting holes 6 on the right mounting steel frame 2. Bolts of the same specification are used to connect and fix the two through the connecting holes 5 and mounting holes 6, thereby reinforcing adjacent units and making the entire steel frame structure a more stable whole. The buffer pad 13 can absorb and buffer the impact force between the convex strip 12 and the limiting groove 11, reducing hard collisions between components. The above is the working principle of this type of large facade unit curtain wall used in public buildings.
