Description

Technical Field

[0001] This invention relates to the field of curtain wall technology, and more specifically to an adjustable building curtain wall structure that is easy to install. Background Technology

[0002] During the installation of building curtain wall structures, embedded parts are typically first installed in the wall. Then, the columns and beams are fixed to the embedded parts in sequence. After adjusting the curtain wall frame formed by the columns and beams, the curtain wall body needs to be aligned with the curtain wall frame and directly connected to the wall. The installation process is quite complex, requiring workers to handle tedious procedures at heights. Furthermore, the heat generated during welding of the frame can easily cause chemical decomposition, material deformation, and thermal expansion of the bolts that fix the embedded parts, affecting the structural integrity and fixing capacity of the bolts. Once welding is completed, modifications or repairs are difficult and may require destructive operations to replace the curtain wall or connecting components.

[0003] While modular prefabricated curtain walls can be used in existing technologies, the fixed angle of the curtain wall panels during installation cannot meet the needs of curtain walls with different building processes. When dealing with curtain walls that require tilting, the overall size and angle of the frame must be adjusted to achieve the tilt, which involves a large amount of work. Furthermore, it is not possible to adjust the panel angle after installation without changing the frame. Therefore, an adjustable building curtain wall structure that is easy to install is provided. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable building curtain wall structure that is easy to install, so as to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An easy-to-install adjustable building curtain wall structure, including an insulation and sealing panel;

[0007] The frame is composed of crossbeams and columns, with two crossbeams and two columns. A connecting plate is fixedly connected to the side of the crossbeam near the external wall. A connecting block that engages with the column is provided on the side of the connecting plate near the crossbeam. The inner wall of the cavity formed by the connecting plate and the crossbeam is in contact with the outer surface of the thermal insulation sealing board. A panel is rotatably connected to the column through a limiting groove opened on its inner wall. The panel is located in the space enclosed by the crossbeam and the column. An adjustment component for adjusting the panel angle is provided on the inner side of the lower crossbeam.

[0008] The adjusting component adopts a separable structure. The adjusting component includes a ring, which is rotatably connected to the middle position inside the crossbeam. Positioning shafts are rotatably connected to both sides inside the crossbeam. There are two positioning shafts, which are symmetrically distributed around the ring. The outer circumference of the positioning shaft is threaded with a positioning plate that is slidably connected to the inside of the crossbeam. The top of the positioning plate is movably connected to the bottom of the panel.

[0009] As a preferred embodiment of the present invention, a rotating block is detachably connected to the side of the panel, the rotating block is rotatably connected to a limiting groove, and the limiting groove is located in the upper half of the column.

[0010] The bottom of the panel is detachably connected to a locking block, and the bottom of the locking block has a slot that engages with the top of the positioning plate.

[0011] In a preferred embodiment of the present invention, the ring is slidably connected to a positioning block through a through hole formed inside it;

[0012] The positioning block includes a long rod that is slidably connected to the through hole. The side of the long rod near the center of the ring is set as an inclined surface, and an arc-shaped toothed block is fixedly connected to the side of the long rod away from the center of the ring. The arc-shaped toothed block is a semi-ring structure. Two arc-shaped toothed blocks can fit together to form a closed toothed ring. A return spring connected to the inside of the ring is sleeved on the outer circumference of the long rod.

[0013] As a preferred embodiment of the present invention, the positioning shaft includes a lead screw threadedly connected to the outer side of the positioning plate, and a gear is fixedly connected to the other end of the lead screw, the gear meshing with the arc-shaped toothed block of the positioning block.

[0014] As a preferred technical solution of the present invention, a driving component is inserted into the outer side of the crossbeam below. The driving component includes a plug that engages with the inner side of the ring, and a rotating handle is fixedly connected to the other end of the plug.

[0015] The insert consists of a stop block and a retaining strip. Two retaining strips are symmetrically fixed to the outside of the stop block, and the stop block is shaped like a frustum.

[0016] As a preferred technical solution of the present invention, a sealing element is rotatably connected inside the connecting plate to compress the rear side of the thermal insulation sealing plate. The sealing element includes a push plate slidably connected to one side of the connecting plate. An arc-shaped groove is provided on one side of the push plate. A connecting rod that slides inside the connecting plate is slidably connected inside the arc-shaped groove. A convex block that is rotatably installed inside the connecting plate is fixedly connected to the other end of the connecting rod. A rack is fixedly connected to the outside of the convex block.

[0017] The rotation center axis of the convex block does not coincide with the center axis of the connecting rod;

[0018] The length of the arc-shaped groove is greater than the diameter of the connecting rod, and the connecting rod can move radially inside the arc-shaped groove.

[0019] As a preferred technical solution of the present invention, the column is provided with a second sealing element for pressing the side of the panel. The second sealing element includes a ball shaft located on the side of the column. In the initial state, the ball shaft is embedded in the hemispherical groove of the column. The spherical surface of the ball shaft is connected to a push block 1 that slides with the inside of the column through a straight rod. The inclined surface of the push block 1 is in contact with the second push block that slides with the inside of the column. The side of the push block 2 away from the push block 1 is provided with a sealing strip that is in contact with the side of the panel.

[0020] As a preferred technical solution of the present invention, the connecting block has a rectangular groove on the side near the column for engaging with the side of the column, and irregular grooves are provided on both sides of the connecting block.

A toothed plate is fixedly connected to the side of the connecting strip near the connecting plate. The connecting strip is engaged in the inner side of adjacent irregular grooves. The toothed plate and the toothed strip are meshed together.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By adjusting the settings, the drive unit can be inserted into the ring after the device is installed on the wall. At this time, the positioning block on the outside of the ring moves away from the ring until the outside of the positioning block engages with the positioning shaft. Then, the drive unit is rotated. The rotation of the drive unit can drive the positioning shaft to rotate, and the rotation of the positioning shaft can drive the positioning plate to move. The movement of the positioning plate can drive the bottom end of the panel to move through the locking block. The top end of the panel rotates around the limiting groove, thereby achieving the purpose of adjusting the angle of the installed panel. Attached Figure Description

[0036] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0037] refer to Figure 1 , Figure 6 and Figure 5 Two sets of perpendicular beams 21 and columns 22 together form the frame 2. A panel 3 is placed within the cavity formed by the beams 21 and columns 22. Each of the two columns 22 has a limiting groove 221 at its top edge on one opposite side. The inner side of the limiting groove 221 can be rotatably connected to a rotating block 51, which can engage and fix the side of the panel 3. The limiting groove 221, rotating block 51, and panel 3 are all detachable structures. After panel 3 is disassembled, the rotating block 51 can still engage with the top edge of a subsequently installed panel 3.

[0038] refer to Figure 1 , Figure 3 and Figure 4 A locking block 52 is detachably connected to the bottom of panel 3. The bottom of locking block 52 has a slot, the inner side of which engages with the positioning plate 212 of the adjusting component. The slot size is slightly larger than the positioning plate 212, ensuring that the rotation of locking block 52 does not interfere with the positioning plate 212. The symmetrically arranged positioning plates 212 are slidably connected in the slots on both sides of the crossbeam 21. The bottom of the positioning plate 212 is threadedly connected to the lead screw of the positioning shaft 213, the other end of which is fixedly connected to the positioning shaft 213. The positioning shaft 213 is rotatably connected in a groove inside the crossbeam 21, and the outer side of the positioning shaft 213 can engage with the outer side of the opened positioning block 215. The positioning block 215 includes a long rod that is slidably connected to the through hole of the ring 214. The side of the long rod near the center of the ring 214 is set as an inclined surface. An arc-shaped toothed block is fixedly connected to the side of the long rod away from the center of the ring 214. The arc-shaped toothed block is a semi-ring structure. Two arc-shaped toothed blocks can fit together to form a closed toothed ring. The arc-shaped toothed block is connected to the outside of the ring 214 through a return spring. The ring 214 is rotatably mounted in the internal channel of the crossbeam 21. Symmetrically symmetrical through holes are provided on the outer side of the ring 214 to restrict the sliding trajectory of the positioning block 215. The through holes pass through the ring 214. Two semi-circular grooves are provided on another symmetrical position on the inner wall of the ring 214. These semi-circular grooves can engage with the retaining strip on the outer side of the insert block 61. The retaining strip and the abutment together constitute the insert block 61, which can be embedded in the cavity of the ring 214. The abutment is frustum-shaped, with one end of the frustum-shaped abutment having a large diameter fixedly connected to the insert block 61. The diameter of the other end of the frustum-shaped abutment is equal to the initial distance between the inclined surfaces of the two long rods. When the abutment is inserted into the cavity of the ring 214, the side of the abutment always fits against the inclined surfaces of the long rods. The insert block 61 and the rotating handle 62 together constitute the driving component 6. The driving component 6 and the crossbeam 21 are separate structures, and the driving component 6 can be pulled out when not in use.

[0039] Before the curtain wall is installed on the wall, the positions of the horizontal beams 21 and the columns 22 are adjusted according to requirements so that the cavity size they form meets the installation requirements of the panel 3. Then, the rotating block 51 and the locking block 52 are installed at the limiting groove 221 and the positioning plate 212 respectively, and then the panel 3 is snapped into the cavity of the frame 2. After the unit curtain wall is installed, the curtain wall structure is connected to the anchor bolts through existing chemical anchor bolts and connectors. When the curtain wall appearance requires a tilt angle to enhance its artistic appeal, the worker can insert the drive component 6 at the lower crossbeam 21. The insert block 61 of the drive component 6 engages with the ring 214 via a locking strip. Simultaneously, the tilted side of the insert block 61 presses against the long rod of the positioning block 215, causing the long rod of the positioning block 215 to slide in the through hole until the insert block 61 is fully inserted into the cavity of the ring 214. The distance the long rod moves is equal to the distance from the outer side of the positioning block 215 to the outer side of the gear of the positioning shaft 213. At this point, the long rod drives the arc-shaped toothed block of the semi-ring structure to move to engage with the gear of the positioning shaft 213. The arc-shaped toothed block, which was in a complete ring state with the outer side of the ring 214 in contact with the ring, moves to a state of two semi-rings with a certain gap in the middle. The two semi-rings can still... The positioning shaft 213 is driven to rotate cyclically, and the inner groove of the crossbeam 21 meets the size requirements for the opening and rotation of the positioning block 215. The screw threads of the two positioning shafts 213 are opposite in direction. When the positioning block 215 rotates and drives the gears of the two positioning shafts 213 to rotate in the opposite direction, the screws of the two positioning shafts 213 can drive the positioning plate 212 to move in the same direction. The positioning plate 212 slides smoothly in the slots on both sides of the crossbeam 21, which can drive the locking block 52 and the bottom end of the panel 3 that is engaged with the locking block 52 to move. At this time, the top of the panel 3 rotates around the rotating block 51, so that the frame 2 and the panel 3 do not need to be disassembled as a whole, or the frame 2 needs to be structurally adjusted. The angle of the panel 3 can also be adjusted. After the adjustment is completed, the side of the panel 3 can be filled and sealed.

[0040] like Figure 1 , Figure 2 and Figure 7As shown, after multiple curtain walls are installed, the expansion joints between adjacent curtain walls need to be filled. This is typically done using a seismic-resistant component 4, which consists of a connecting strip 41 and a toothed plate 42. The connecting strip 41 is a polygon with the same shape as the gap between adjacent curtain walls, and the bottom end of the connecting strip 41 is fixedly connected to a toothed plate 42 that engages with a sealing component. The gap between adjacent curtain walls is formed by two fitting connecting blocks 24. The outer side of the horizontal beam 21 is fixedly connected to the connecting plate 23 via two symmetrically arranged connecting blocks 24. A rectangular groove is provided on the side of the connecting block 24 near the column 22 to engage with the side of the column 22. Irregular grooves 241 are provided on both sides of the connecting block 24, and on the other two sides as well. One of the irregular grooves 241 of the connecting block 24, the connecting plate 23, and the horizontal beam 21 form a cavity for insulation. The sealing plate 1 can be inserted into the cavity. The side of the thermal insulation sealing plate 1 near the panel 3 is made of flexible material. After being inserted into the cavity, it can fit against the rear side of the panel 3 to achieve sealing of the rear side and side of the panel 3. The length of the cavity is greater than the size of the crossbeam 21. Therefore, the thermal insulation sealing plate 1 can fully cover the rear side of the crossbeam 21 and the column 22. The irregular groove 241 away from the cavity and the irregular groove 241 on the side of the adjacent frame 2 together form an expansion joint. The expansion joint is into which the seismic component 4 is inserted.

[0041] like Figure 8 and Figure 9 As shown, a sealing element 1, which compresses the rear side of the thermal insulation sealing plate 1, is rotatably connected inside the connecting plate 23. The sealing element 1 includes a push plate 231 slidably connected to one side of the connecting plate 23. An arc-shaped groove is formed on one side of the push plate 231, and a connecting rod 233, which slides inside the connecting plate 23, is slidably connected inside the arc-shaped groove. The length of the arc-shaped groove is greater than the diameter of the connecting rod 233, and the connecting rod 233 can move radially inside the arc-shaped groove. The lateral movement of the connecting rod 233 can drive the push plate 231 to move. A convex block 234, which is rotatably installed inside the connecting plate 23, is fixedly connected to the other end of the connecting rod 233. A rack 235 is fixedly connected to the outside of the convex block 234, and the rotation center axis of the convex block 234 does not coincide with the center axis of the connecting rod 233.

[0042] like Figure 2 and Figure 10As shown, the column 22 is equipped with a second sealing element that presses against the side of the panel 3. The second sealing element includes a ball shaft 222 located on the side of the column 22. The ball shaft 222 consists of a ball, a straight rod, and a second return spring. In the initial state, the ball of the ball shaft 222 is embedded in the hemispherical groove of the column 22. The inner surface of the hemispherical groove of the column 22 is connected to the ball of the ball shaft 222 through the second return spring. The second return spring is sleeved on the outside of the straight rod. The spherical surface of the ball shaft 222 is connected to the column 22 through the straight rod. Push block 1 223 slides internally. Push block 1 223 has a slope that is attached to push block 224 that slides internally with column 22. The outer side of push block 224, opposite to push block 1 223 and push block 224, is also set as a slope. The inclination angle of the two slopes changes the direction of the push force of push block 1 223 to a vertical direction. This vertical force can push push block 224. A sealing strip is provided on the side of push block 224 away from push block 1 223, which is attached to the side of panel 3.

[0043] In this embodiment, while the seismic damping component 4 is inserted into the expansion joint, the toothed plate 42 fixedly installed at the bottom end of the connecting strip 41 contacts the toothed rack 235 of the sealing component 1 above and below in sequence. As the toothed plate 42 moves down, the toothed rack 235 that meshes with it drives the convex block 234 to rotate. The rotation of the convex block 234 causes its top end to move from the inner wall of the connecting plate 23 away from the crossbeam 21 to the inner wall close to the crossbeam 21. The rotation of the convex block 234 drives the connecting rod 233 to move synchronously. The longitudinal displacement caused by the rotation causes the connecting rod 233 to slide in the arc groove. The lateral displacement caused by the rotation causes the connecting rod 233 to move the push plate 231, which is completely embedded in the inner side of the connecting plate 23. This causes the push plate 231 to apply pressure to the corners of the insulation sealing plate 1. The fixed-size insulation sealing plate 1 undergoes a certain deformation after being pressed at all four corners. Under the pressure of the push plate 231, the four corners are further tightly fitted to the sides of the insulation sealing plate 1. The sides of the insulation sealing plate 1 are also tightened due to the deformation of the four corners, so that the sides of the insulation sealing plate 1 can also be tightly fitted to the sides of the panel 3.

[0044] When the seismic-resistant component 4 moves down to the middle height of the frame 2, the connecting strip 41 can contact the ball shaft 222 and squeeze the ball shaft 222, causing the ball shaft 222 to move towards the column 22. The ball shaft 222 drives the push block 1 223 to move. The movement of push block 1 223 applies a force to the inclined surface of the mating push block 224. Push block 1 223 and push block 224 form a wedge mechanism, converting the force pushing push block 1 223 into the force pushing push block 224. Push block 224 applies a force to the sealing strip, making the sealing strip tightly fit with the side of the panel 3, further sealing the side of the panel 3. This also strengthens the sealing performance of the panel 3 when connecting adjacent curtain walls.
