Description

Technical Field

[0001] This invention relates to the field of architectural decoration, specifically to a prefabricated building curtain wall and its application method. Background Technology

[0002] A building curtain wall is a building envelope or decorative structure composed of a supporting structural system and panels. It has a certain displacement capacity relative to the main structure and does not share the loads of the main structure. It is hung like a curtain, hence also called a suspended wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It consists of a structural frame and inlaid panels, and does not bear the loads and forces of the main structure.

[0003] Modern curtain wall panels are directly embedded in the structural frame, making the installation and removal process extremely complicated. Furthermore, due to the gaps in the embedded structure, the panels can rub against the frame in windy weather, easily leading to damage. Additionally, modern curtain walls often use long bolts to fix them to the building's exterior, which generally have a short lifespan, resulting in high maintenance costs. Moreover, rusted bolts can weaken the connection between the curtain wall and the building's exterior, posing a significant risk of curtain wall detachment. Summary of the Invention

[0004] (I) Technical Solution

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated building curtain wall and its usage method, comprising a curtain wall body, a fixing frame, and a support mechanism. The curtain wall body is vertically arranged on the periphery of the building and parallel to the periphery of the building. The curtain wall body is fixedly connected to the periphery of the building through four sets of fixing frames. The support mechanism is fixedly connected to the side of the curtain wall body adjacent to the periphery of the building.

[0006] Preferably, the curtain wall body includes an installation frame, an installation groove, a fixing hole, a fixing plate, a wall panel, and a limiting groove. The installation groove is opened on the side of the installation frame adjacent to the building perimeter. The wall panel is installed inside the installation groove. The fixing plate is fixedly connected to the top of the installation groove on the side away from the building perimeter. The limiting groove is opened at the bottom of the fixing plate. The fixing hole is opened on the side end face of the installation frame.

[0007] Preferably, the wall panel is inside the mounting groove, and the lower part of the wall panel is inside the limiting groove. The upper end face of the wall panel is 5cm higher than the lower end face of the fixing plate. The height of the fixing plate is 10cm. The width of the limiting groove is twice the thickness of the mounting groove, so that the wall panel is limited inside the fixing plate, and the installation and removal of the wall panel and the mounting groove are very convenient.

[0008] Preferably, the fixing holes are symmetrically arranged in four groups at the four corners of the side end face of the mounting frame, and the fixing holes penetrate through the side end face of the mounting frame, thereby facilitating the fixing between the fixing frame and the curtain wall body.

[0009] Preferably, the fixing frame includes a connecting block, a fixing groove, a long bolt, a nut, a connecting rod, a fixing block, a buffer groove, a limiting post, and a rubber pad. The connecting block is fixedly connected to one end of the connecting rod. The fixing groove is formed on the upper end face of the connecting block. The long bolt passes through the side end face of the connecting block, and the connecting block passes through the fixing groove. Two sets of nuts are fixedly connected to both ends of the connecting block. The fixing block is rotatably connected to the end of the connecting rod opposite to the connecting block. The buffer groove is formed on the upper end face of the fixing block. The limiting post is fixedly connected to the end of the connecting rod opposite to the connecting block. The rubber pad is slidably connected to the side end face of the connecting rod.

[0010] Preferably, two sets of fixing grooves are respectively opened on the upper and lower end faces of the connecting block. The size of the fixing grooves is adapted to the mounting frame. The fixing grooves lock the mounting frame, and the long bolts pass through the fixing holes. The two sets of nuts fix the long bolts to the connecting block. Washers and rubber washers are provided on the side of the nuts adjacent to the connecting block, so that the long bolts are not affected by wind and rain when fixed to the connecting block, and the long bolts are not affected by corrosion, thus affecting the tight connection between the long bolts and the connecting block.

[0011] Preferably, the limiting post and the rubber pad are both inside the buffer groove, and the size of the limiting post and the rubber pad is adapted to the buffer groove, so that the connecting rod fixes the curtain wall body through the connecting block. When subjected to external wind force, the rubber pad effectively prevents the connection between the connecting rod and the fixing block from being rigidly pulled, thereby improving the service life of the fixing frame. Each side of the fixing block is provided with a set of fixing ears, which facilitates the fixing of the fixing block to the building perimeter.

[0012] Preferably, the support mechanism includes a support frame, a pressure plate, an electric push rod, and a connecting column. The electric push rod is fixedly connected to the side of the support frame away from the building's perimeter. One end of the connecting column passes through the support frame and is fixedly connected to the output end of the electric push rod. The pressure plate is fixedly connected to the end of the connecting column away from the electric push rod.

[0013] Preferably, the pressure plate has two layers, with the side that is fixedly connected to the connecting column being made of rubber and the other side being made of sponge. This ensures that the pressure plate will not damage the wall panel when it presses against it, and also provides a certain amount of cushioning to prevent the wall panel from colliding and being damaged with the mounting groove in windy weather.

[0014] Preferably, during use, the wall panel is first installed inside the fixing plate, with the lower part of the wall panel inside the limiting groove and the adjacent side of the wall panel and the fixing plate abutting each other. Then, the pressure plate is driven by the electric push rod and connecting column to hold the wall panel in place, and the sponge side of the pressure plate is kept completely flat, so that the wall panel is fixed and secure inside the installation groove. Then, the four sets of fixing brackets are used to clamp the installation frame through the fixing groove. Long bolts are passed through the fixing holes and then the long bolts are fixed with nuts, so that the entire curtain wall is integrated. Finally, the fixing ears on both sides of the fixing block are fixed to the outer perimeter of the building using through bolts.

[0015] (II) Beneficial Effects

[0016] This invention provides a prefabricated building curtain wall and its usage method, which has the following advantages: The wall panels are installed inside the mounting groove via limiting grooves and fixing plates, improving the convenience of wall panel installation and disassembly; the wall panels are held in place by a pressure plate, which has two layers, one side for fixing to the connecting column is made of rubber, and the other side is made of sponge material. This prevents damage to the wall panels when the pressure plate holds them in place and provides a certain degree of cushioning, ensuring that the wall panels will not collide with the mounting groove and be damaged in windy weather. The fixing frame is used to fix the curtain wall body by fitting with the mounting frame and fixing holes through fixing grooves and long bolts. The long bolts are secured at both ends with nuts, ensuring a tight fixation between the fixing frame and the curtain wall body. Simultaneously, one end of the connecting rod is limited inside the buffer groove by a limiting post and a rubber pad, allowing the connecting rod to rotate and connect with the fixing block. The rubber pad effectively prevents wear and tear at the connection point between the limiting post and the fixing block under prolonged external tension, thus affecting the fixing effect of the curtain wall. This extends the service life of the fixing frame and reduces the maintenance cost of the curtain wall. Attached Figure Description

[0029] This invention provides a prefabricated building curtain wall, including a curtain wall body 1, a fixing frame 2, and a support mechanism 3. The curtain wall body 1 is vertically arranged on the periphery of the building and parallel to the periphery of the building. The curtain wall body 1 is fixedly connected to the periphery of the building through four sets of fixing frames 2. The support mechanism 3 is fixedly connected to the side of the curtain wall body 1 adjacent to the periphery of the building.

[0030] Preferably, the curtain wall body 1 includes an installation frame 4, an installation groove 5, a fixing hole 6, a fixing plate 7, a wall panel 8, and a limiting groove 9. The installation groove 5 is opened on the side of the installation frame 4 adjacent to the building perimeter. The wall panel 8 is installed inside the installation groove 5. The fixing plate 7 is fixedly connected to the top of the installation groove 5 on the side away from the building perimeter. The limiting groove 9 is opened at the bottom of the fixing plate 7. The fixing hole 6 is opened on the side end face of the installation frame 4.

[0031] Preferably, the wall panel 8 is inside the mounting groove 5, and the lower part of the wall panel 8 is inside the limiting groove 9. The upper end of the wall panel 8 is 5cm higher than the lower end of the fixing plate 7. The height of the fixing plate 7 is 10cm. The width of the limiting groove 9 is twice the thickness of the mounting groove 5, so that the wall panel 8 is limited inside the fixing plate 7, and the installation and removal of the wall panel 8 and the mounting groove 5 are very convenient.

[0032] Preferably, four sets of fixing holes 6 are symmetrically opened at the four corners of the side end face of the mounting frame 4, and the fixing holes 6 penetrate through the side end face of the mounting frame 4, thereby facilitating the fixing between the fixing frame 2 and the curtain wall body 1.

[0033] Preferably, the fixing frame 2 includes a connecting block 10, a fixing groove 11, a long bolt 12, a nut 13, a connecting rod 14, a fixing block 15, a buffer groove 16, a limiting post 17, and a rubber pad 18. The connecting block 10 is fixedly connected to one end of the connecting rod 14. The fixing groove 11 is opened on the upper end face of the connecting block 10. The long bolt 12 passes through the side end face of the connecting block 10, and the connecting block 10 passes through the fixing groove 11. Two sets of nuts 13 are fixedly connected to both ends of the connecting block 10. The fixing block 15 is rotatably connected to the end of the connecting rod 14 away from the connecting block 10. The buffer groove 16 is opened on the upper end face of the fixing block 15. The limiting post 17 is fixedly connected to the end of the connecting rod 14 away from the connecting block 10. The rubber pad 18 is slidably connected to the side end face of the connecting rod 14.

[0034] Preferably, two sets of fixing grooves 11 are respectively opened on the upper and lower end faces of the connecting block 10. The size of the fixing grooves 11 is adapted to the mounting frame 4. The fixing grooves 11 are locked in the mounting frame 4, and the long bolts 12 pass through the fixing holes 6. Two sets of nuts 13 fix the long bolts 12 to the connecting block 10. Washers and rubber pads are provided on the side of the nuts 13 adjacent to the connecting block 10, so that the long bolts 12 will not be affected by wind and rain when they are fixed to the connecting block 10, and the long bolts 12 will not be affected by corrosion and have a tight connection with the connecting block 10.

[0035] Preferably, the limiting post 17 and the rubber pad 18 are both inside the buffer groove 16, and the limiting post 17 and the rubber pad 18 are adapted to the size of the buffer groove 16, so that the connecting rod 14 fixes the curtain wall body 1 through the connecting block 10. When subjected to external wind force, the rubber pad 18 effectively prevents the connecting rod 14 from being rigidly pulled on the connection with the fixing block 15, thereby improving the service life of the fixing frame 2. A set of fixing ears is provided on each side of the fixing block 15, which facilitates the fixing of the fixing block 15 to the building perimeter.

[0036] Preferably, the support mechanism 3 includes a support frame 19, a pressure plate 20, an electric push rod 21, and a connecting column 22. The electric push rod 21 is fixedly connected to the side of the support frame 19 away from the outer perimeter of the building. One end of the connecting column 22 passes through the support frame 19 and is fixedly connected to the output end of the electric push rod 21. The pressure plate 20 is fixedly connected to the end of the connecting column 22 away from the electric push rod 21.

[0037] Preferably, the pressure plate 20 is divided into two layers, one of which is made of rubber and the other of which is made of sponge. This ensures that the pressure plate 20 will not damage the wall panel 8 when it holds it against the wall panel 8, and also has a certain buffering capacity to ensure that the wall panel 8 will not collide with the mounting groove 5 in windy weather.

[0038] Preferably, in use, the wall panel 8 is first installed inside the fixing plate 7, so that the lower part of the wall panel 8 is inside the limiting groove 9, and the side of the wall panel 8 adjacent to the fixing plate 7 abuts against each other. Then, the pressure plate 20 is driven by the electric push rod 21 and the connecting column 22 to hold the wall panel 8 against it, and the sponge side of the pressure plate 20 is completely flattened, so that the wall panel 8 is fixed and securely fixed inside the mounting groove 5. Then, the four sets of fixing brackets 2 are clamped into the mounting frame 4 through the fixing groove 11, and the long bolts 12 are passed through the fixing holes 6 and then the long bolts 12 are fixed with nuts 13, so that the entire curtain wall is integrated. Finally, the fixing ears on both sides of the fixing block 15 are fixed to the outer perimeter of the building with through bolts.

[0039] In summary, this prefabricated building curtain wall, firstly, improves the ease of installation and disassembly of the wall panel 8 by installing it inside the mounting groove 5 through the limiting groove 9 and the fixing plate 7; secondly, the wall panel 8 is held in place by the pressure plate 20, which is divided into two layers, with the side that is fixedly connected to the connecting column 22 being made of rubber and the other side being made of sponge. Thus, the pressure plate 20 will not damage the wall panel 8 when it holds it in place, and it also has a certain buffering capacity to ensure that the wall panel 8 will not collide with the mounting groove 5 and be damaged in windy weather. The fixing bracket 2 is adapted to the mounting frame 4 and fixing hole 6 through the fixing groove 11 and the long bolt 12 to fix the curtain wall body 1. The two ends of the long bolt 12 are fixed by the nuts 13, so that the fixing bracket 2 is fixed and fastened to the curtain wall body 1. At the same time, one end of the connecting rod 14 is limited in the buffer groove 16 by the limiting post 17 and the rubber pad 18, so that the connecting rod 14 is rotatably connected to the fixing block 15. The rubber pad 18 can effectively prevent the connection point between the limiting post 17 and the fixing block 15 from being worn by external tension for a long time, which would affect the fixing effect of the curtain wall. As a result, the service life of the fixing bracket 2 will be longer, and the maintenance cost of the curtain wall will be reduced.
