Description

Technical Field

[0001] This utility model relates to a modular building curtain wall unit. Background Technology

[0002] As the exterior enclosure structure of a building, the curtain wall not only has a decorative function but also needs to meet performance requirements such as waterproofing, windproofing, and thermal insulation. With the development of industrialized construction, modular curtain wall units have been widely used because they can improve construction efficiency and reduce on-site labor intensity.

[0003] In existing technologies, modular curtain wall units are mostly installed using welding, bolting, or snap-fit ​​methods. When using bolting, on-site drilling is required, and the tightening process is cumbersome, which not only reduces installation efficiency but also makes the exposed bolts susceptible to corrosion, affecting connection stability. Furthermore, the operation may damage the curtain panel or frame.

[0004] Curtain wall units with simple snap-fit ​​structures typically connect via a single groove and protrusion. However, this structure is prone to loosening due to vibration, temperature changes, and other factors during long-term use, posing a safety hazard. Furthermore, existing snap-fit ​​structures require high precision in the fit between the curtain panel and the frame; even slight dimensional deviations can lead to installation difficulties or loose connections, affecting the overall performance of the curtain wall. Utility Model Content

[0005] The purpose of this invention is to solve the problems of low installation efficiency and unstable connection in the existing technology, and to provide a modular building curtain wall unit.

[0006] A modular building curtain wall unit includes a frame body fixed to the exterior wall, the frame body including horizontal beams and vertical beams, and the surface of the frame body is covered with a plurality of curtain panels arranged in an array.

[0007] Several fixing blocks are provided on both sides of the vertical beam. Each fixing block includes a square body and a pin protruding from the square body. The pin includes a head and a tail. The diameter of the head gradually increases, and the maximum diameter of the head is greater than the diameter of the tail.

[0008] The back of the curtain panel is provided with several embedded blocks that match the fixing blocks. The embedded blocks are formed together with the main body of the curtain panel. The embedded block includes an embedded body. The surface of the embedded body is provided with a gourd-shaped groove. The inside of the gourd-shaped groove is provided with a retaining ring. The retaining ring is connected to the upper surface of the embedded body by a rivet.

[0009] The gourd-shaped groove includes a first groove and a second groove from bottom to top. The inlet of the first groove has the same diameter as the internal cavity, and the diameter at the inlet is slightly larger than the maximum diameter of the pin. The cross-sectional area at the inlet of the second groove is smaller than the cross-sectional area of ​​the internal cavity, and the diameter at the inlet of the second groove is smaller than the maximum diameter of the pin.

[0010] Furthermore, the number of pins is at least two. Two pins create a multi-point load-bearing structure, significantly improving the stability of the connection between the curtain panel and the frame, preventing the curtain panel from tilting, loosening, or even falling off due to uneven stress, ensuring the curtain wall unit maintains structural integrity during long-term use, and providing a reliable connection foundation for modular installation.

[0011] Furthermore, the square main body is connected to the vertical beam via Phillips head screws. The square main body has through holes on its side, through which the Phillips head screws pass and connect to the side wall of the vertical beam. This Phillips head screw connection method is simple to operate, suitable for quick on-site tightening, and ensures a secure connection between the square main body and the vertical beam. It simplifies the installation process and improves the accuracy and stability of the fixing block installation.

[0012] Furthermore, the retaining ring includes two symmetrically arranged elastic plates. The free ends of the elastic plates have inwardly protruding points. The protrusions of the two elastic plates are connected by a ring buckle. The outer side of the protrusion has a beveled transition, and the inner side has a right-angle transition. This design ensures smooth pin installation and provides a reliable limiting effect after installation, significantly improving the stability of the connection. Moreover, because the inner side has a right-angle transition, the pin is difficult to slip out after installation.

[0013] Furthermore, the horizontal beams and vertical beams are connected perpendicularly. This perpendicular intersecting structure allows the forces on the main frame to be evenly distributed in both longitudinal and transverse directions, effectively dispersing external loads.

[0014] Furthermore, the square body of the fixing block is made of aluminum alloy, and the pin is integrally formed with the square body, with an anti-corrosion coating on the outer surface of the pin. This anti-corrosion coating further enhances the pin's resistance to rust, extends its service life, reduces the risk of connection failure due to rust, and lowers maintenance costs.

[0015] Furthermore, the first and second grooves of the gourd-shaped slot are connected by an arc-shaped transition surface, the radius of curvature of which is 1.2-1.5 times the maximum diameter of the pin head. This arc-shaped transition makes the installation of the curtain panel under its own weight smoother, reducing installation resistance and operational difficulty, while also preventing structural damage to the pins or slots caused by hard impacts, thus improving installation efficiency and component durability.

[0016] Beneficial effects:

[0017] 1. The installation process of this modular building curtain wall unit is efficient and convenient. The pins of the fixing block and the gourd-shaped grooves of the pre-embedded block are precisely matched. During installation, the pins only need to be inserted into the first groove. With the help of the weight of the curtain panel, it can naturally slide into the second groove and be limited by the retaining ring. There is no need to precisely align the installation holes, which significantly shortens the on-site operation time and greatly improves the installation efficiency.

[0018] 2. The connection is stable and reliable. The second groove entrance of the gourd-shaped slot is smaller than the maximum diameter of the pin. Combined with the elastic limiting structure of the retaining ring, it can effectively prevent the pin from falling off. Even under the action of external forces such as vibration and wind, it can still ensure that the curtain panel and the frame body are firmly connected, thus improving the overall safety performance of the curtain wall.

[0019] 3. High versatility: The connection position of the fixing block with the vertical beam can be finely adjusted through the through hole. The embedded block is formed synchronously with the curtain panel and the size is standardized, so that curtain panels and fixing blocks from different batches can be interchanged and adapted to modular mass production and rapid on-site assembly.

These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0030] Example 1: As Figure 1-8 As shown, a modular building curtain wall unit includes a frame body, a curtain panel 6, a fixing block 3, and a pre-embedded block 5.

[0031] The main frame is used to fix it to the exterior wall, serving as the installation base for the curtain panel 6. It includes horizontal beams 1 and vertical beams 2. The horizontal beams 1 and vertical beams 2 are connected perpendicularly to form a grid structure.

[0032] The surface of the main frame is covered with several arrayed curtain panels 6. In this embodiment, the surface of the curtain panels 6 is covered with tempered glass, which enhances the aesthetics. The edges of the curtain panels 6 are provided with EPDM rubber sealing strips (not shown in the figure). The sealing strips have a U-shaped cross-section, wrap around the edges of the curtain panels 6, and have a width of 10mm, which can effectively enhance the sealing between adjacent curtain panels 6.

[0033] Several fixing blocks 3 are provided on both sides of the vertical beam 2. The number of fixing blocks 3 is determined according to the size of the curtain panel 6. In this embodiment, each curtain panel 6 corresponds to 4 fixing blocks 3. The fixing block 3 includes a square body 31 and pins 33. The pins 33 are integrally formed with the square body 31, and there are 2 of them, which are evenly distributed along the length of the square body 31. The pins 33 include a head and a tail. The head is shaped like a frustum cone with a maximum diameter of 8 mm, and the tail has a diameter of 6 mm and a length of 20 mm. The outer surface of the pins 33 is coated with a zinc-nickel alloy anti-corrosion coating with a thickness of 8-10 μm, and the salt spray resistance can reach more than 1000 hours.

[0034] The square body 31 is connected to the vertical beam 2 by a cross screw 4. The side of the square body 31 is provided with a through hole 32, the diameter of which is 6.5mm. The cross screw 4 passes through the through hole 32 and is threaded into the side wall of the vertical beam 2.

[0035] The back of the curtain panel 6 is provided with four embedded blocks 5 that match the fixing blocks 3. The embedded blocks 5 are pre-set in the bottom layer of the curtain panel 6. The embedded block 5 includes an embedded body 51. The surface of the embedded body 51 is provided with a gourd-shaped groove 52. The gourd-shaped groove 52 includes a first groove 521 and a second groove 522 from bottom to top. The first groove 521 and the second groove 522 are connected by an arc-shaped transition surface.

[0036] The gourd-shaped slot 52 has a retaining ring 54 inside. The retaining ring 54 is made of 65Mn spring steel with a thickness of 0.8mm and includes two symmetrically arranged elastic plates. The free end of the elastic plates has an inwardly protruding point 541. The protruding points 541 of the two elastic plates are connected by a ring buckle 542. The embedded body 51 has a rivet hole 53, and the retaining ring 54 is connected to the upper surface of the embedded body 51 by a rivet 55.

[0037] The installation process in this embodiment is as follows:

[0038] S1. Frame main body installation: According to the design dimensions, the horizontal beam 1 and the vertical beam 2 are connected by connecting grooves and connecting protrusions and fixed by welding to form a complete frame main body. Then the frame main body is fixed to the outer wall.

[0039] S2. Fixing block installation: According to the calculated position, place the square body 31 of fixing block 3 next to the vertical beam 2, and connect it to the side wall of the vertical beam 2 by passing the cross screw 4 through the through hole 32. Tighten the cross screw 4 to complete the installation of fixing block 3.

[0040] S3. Curtain panel installation: Move the curtain panel 6 with the pre-embedded block 5 to the installation position, align the gourd-shaped groove 52 of the pre-embedded block 5 with the pin 33 of the fixing block 3. The pin 33 first extends into the gourd-shaped groove 52 through the first groove 521. Release the curtain panel 6. Under its own weight, the curtain panel 6 moves downward with the pre-embedded block 5. The pin 33 slides from the first groove 521 into the second groove 522 along the arc transition surface and pushes open the protrusion 541 of the retaining ring 54. After the pin 33 is fully inserted into the second groove 522, the elastic piece of the retaining ring 54 returns to its original position, and the ring buckle 542 limits the pin 33 in the second groove 522, completing the installation of a single curtain panel 6.

[0041] S4. Repeat the above curtain panel installation steps to cover the entire frame body with all curtain panels 6, and make sure the sealing strips on the edges of adjacent curtain panels 6 fit together to achieve a seal.

[0042] This device significantly improves installation efficiency and connection stability through optimized structural design of the fixing block and the embedded block. The pin of the fixing block and the gourd-shaped groove of the embedded block cooperate, and the curtain panel can slide from the first groove to the second groove by its own weight, without the need for precise alignment of the mounting hole, greatly simplifying on-site operation; the elastic limit of the retaining ring and the size design of the second groove can effectively prevent the pin from falling off, ensuring a firm connection and resisting the influence of external forces such as vibration and wind.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
