Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curtain wall installation, in particular to a sealing device for semi-unit curtain wall. BACKGROUND

[0002] With the rapid development of the construction industry, the all-steel fireproof curtain wall is widely used in large building projects such as high-rise buildings and commercial complexes due to its excellent fireproof performance, high strength and durability. The semi-unit curtain wall, as a curtain wall form that takes into account the convenience of construction and structural stability, plays an important role in building facade decoration and enclosure by combining curtain wall panels with columns and pressure plates. Currently, the sealing installation of all-steel fireproof semi-unit curtain wall generally uses traditional technology: first, manually align and attach the curtain wall panel with the column, then attach the pressure plate to the other side of the curtain wall panel, and finally connect the column, curtain wall panel and pressure plate with bolts, while setting sealing rubber strips on both sides of the curtain wall panel to achieve sealing between the curtain wall panel and the column, and between the curtain wall panel and the pressure plate.

[0003] However, this traditional installation method has obvious defects. First, the bolt is usually arranged at the central part of the pressure plate. When the bolt is tightened, it is equivalent to applying a single-point vertical pressure to the pressure plate. The bolt exerts a large pressure on the central part of the pressure plate and the curtain wall panel, causing the pressure plate and the curtain wall panel to deform with the central part sinking and the two sides rising. The sealing rubber strip is usually installed at the edge of the contact surface between the pressure plate and the curtain wall panel and the column. Once the pressure plate and the curtain wall panel deform as described above, a gap is easily formed at the sealing rubber strip. Second, it is difficult to control the tightening force of the bolt during installation. If it is tightened too tightly, the compression amount of the sealing rubber strip will exceed the reasonable range, greatly shortening the service life and reducing the reliability of the curtain wall sealing system.

Embodiment 2

[0036] With reference to Figures 1-11 For the second embodiment of the application, the embodiment is based on the previous embodiment.

[0037] Specifically, the trigger 23 comprises a first hanger 23-1 fixedly connected to one side of the inner cavity of the stand column 11, one side of the first hanger 23-1 is provided with a second hanger 23-2 which cooperates with the first hanger 23-1, one side of the movable plate 22 is provided with a first sliding groove 23-3, one side of the second hanger 23-2 is slidably connected with the first sliding groove 23-3, the inner cavity of the first sliding groove 23-3 is fixedly connected with a first spring 23-4 away from one side of the second hanger 23-2, one side of the first spring 23-4 close to the second hanger 23-2 is fixedly connected with the second hanger 23-2, and one side of the second hanger 23-2 away from the first spring 23-4 is fixedly connected with a trigger block 23-5, and one side of the trigger block 23-5 away from the second hanger 23-2 is provided with a slope groove 23-6.

[0038] Through the cooperation of the first hanger 23-1 and the second hanger 23-2, the movable plate 22 is stably limited in the normal state, and the stability of the positions of the components in the early installation stage is ensured, and the first spring 23-4 as an elastic element provides elastic restoring force for the movement of the second hanger 23-2, when the fixing rod 21 rotates and contacts the slope groove 23-6 of the trigger block 23-5, with the gradual decrease of the angle in the slope groove 23-6, the pushing force of the fixing rod 21 can overcome the elastic force of the first spring 23-4, and the trigger block 23-5 is pushed to move, and then the second hanger 23-2 is separated from the first hanger 23-1, so that the limitation of the movable plate 22 is removed, and the conditions for the subsequent movement of the movable plate 22 under the action of the fixing rod 21 and the exertion of force on the curtain wall plate 14 by the connecting rod 24 are created, so that the compaction assembly 2 can be accurately started to work according to the design intention when the fixing rod 21 is rotated to a specific stage, and the basis for the uniform compaction of the curtain wall plate 14 is laid.

[0039] Specifically, the surface of the movable plate 22 is provided with a through groove, and the inner cavity of the through groove is rotationally connected with a rotating ring 23-7. One side of the rotating ring 23-7 is in contact with the fixed rod 21.

[0040] When the fixed rod 21 rotates, if it directly contacts the movable plate 22, frequent friction will cause the surface material of the movable plate 22 to gradually wear, affecting its normal function, and even causing the movable plate 22 to jam and other faults. By arranging a buffer layer between the fixed rod 21 and the movable plate 22 through the rotating ring 23-7, when the fixed rod 21 rotates, the rotating ring 23-7 can rotate with it, converting the original sliding friction into rolling friction, greatly reducing the friction. This not only effectively reduces the wear degree of the movable plate 22 and prolongs its service life, but also ensures that the movable plate 22 can move smoothly under the action of the fixed rod 21, continuously and effectively driving the connecting rod 24 to exert force on the curtain wall plate 14, making the entire compaction process more stable and reliable.

[0041] Specifically, the other side of the surface of the connecting rod 24 is sleeved with a second spring 23-8, one side of the second spring 23-8 is fixedly connected with the movable plate 22, and the other side of the second spring 23-8 is fixedly connected with the inner cavity of the stand column 11.

[0042] When the curtain wall plate 14 needs to be disassembled or adjusted, the second spring 23-8 can generate a restoring force due to its elastic deformation, assisting the connecting rod 24 to reset, reducing the difficulty and workload of manual operation, improving the operability and flexibility of the device, and facilitating the maintenance and adjustment work of the curtain wall in the subsequent use process.

[0043] Specifically, the tensioning member 26 includes a slope block 26-1 slidingly connected to the surface of the connecting rod 24, one side of the slope block 26-1 penetrating the connecting rod 24 is fixedly connected with a third spring 26-2, and the other side of the third spring 26-2 away from the slope block 26-1 is fixedly connected with the inner cavity of the connecting rod 24. One side of the inner cavity of the connecting groove 25 is fixedly connected with a fixed ring 26-3 matched with the slope block 26-1, and the other side of the fixed ring 26-3 is provided with a filling portion 26-4.

[0044] In the installation process, when the connecting groove 25 and the connecting rod 24 are butt jointed, the slope block 26-1 is in contact with the fixed ring 26-3, and under the action of pressure, the slope block 26-1 will shrink into the connecting rod 24, so that the third spring 26-2 is elastically deformed to store energy. With the continuous entry of the connecting rod 24 into the connecting groove 25, when the slope block 26-1 passes the fixed ring 26-3, the third spring 26-2 releases energy to drive the slope block 26-1 to reset, so that it is clamped in the connecting groove 25. This clamping method not only quickly connects the curtain wall plate 14 and the stand column 11, improves the installation efficiency, but also can withstand the force applied to the curtain wall plate 14 during the subsequent compaction of the assembly 2, maintains the stability of the connection, and ensures that the curtain wall plate 14 will not easily loosen or shift during the stress process. Even under the influence of external environmental factors (such as wind load, temperature change, etc.), the tensioning piece 26 can maintain reliable connection between the curtain wall plate 14 and the stand column 11, and protect the overall structural performance of the curtain wall.

[0045] Specifically, the filling part 26-4 includes a movable ring 26-41 arranged on one side of the fixed ring 26-3, both sides of the movable ring 26-41 are fixedly connected with a moving plate 26-42, both sides of the inner cavity of the connecting groove 25 are provided with a moving groove 26-43 which cooperates with the moving plate 26-42, one side of the moving plate 26-42 is fixedly connected with a fourth spring 26-44, one side of the fourth spring 26-44 is fixedly connected with the inner cavity of the moving groove 26-43, the bottom of the moving groove 26-43 is provided with a through groove 26-45, one side of the inner cavity of the through groove 26-45 is fixedly connected with a cylinder 26-46, one side of the cylinder 26-46 is slidingly connected with a piston rod 26-461, one side of the piston rod 26-461 away from the cylinder 26-46 is fixedly connected with the moving plate 26-42, both sides of the cylinder 26-46 are communicated with a pipeline 26-47, one side of the pipeline 26-47 away from the cylinder 26-46 penetrates through the curtain wall plate 14 and is communicated with a first air bag 26-48, the surface of the first air bag 26-48 is covered with a first bonding block 26-49 which is fixedly connected on one side of the curtain wall plate 14, and the other side of the pipeline 26-47 away from the cylinder 26-46 penetrates through the curtain wall plate 14 and is communicated with a second air bag 26-50, the surface of the second air bag 26-50 is covered with a second bonding block 26-51 which is fixedly connected on the other side of the curtain wall plate 14.

[0046] The function of the tensioning member 26 is further optimized and improved by the filling portion 26-4. When the slope block 26-1 is disengaged from the fixed ring 26-3 and is reset, the slope surface of the slope block 26-1 pushes the movable ring 26-41 to move, drives the moving plate 26-42 to slide in the moving groove 26-43 and compresses the fourth spring 26-44, until the slope block 26-1 is retracted into the connecting rod 24 under the pressure, and the third spring 26-2 is elastically deformed to store energy. When the slope block 26-1 passes the movable ring 26-41, the third spring 26-2 releases the energy, drives the slope block 26-1 to reset, and is clamped with the movable ring 26-41. Subsequently, when the fixed rod 21 drives the movable plate 22 to move, the slope block 26-1 is stressed again, drives the movable ring 26-41 and the moving plate 26-42 to drive the piston rod 26-461 to slide in the cylinder 26-46, and fills the gas in the cylinder 26-46 into the first air bag 26-48 and the second air bag 26-50 through the pipeline 26-47. The expanded air bags respectively extend from the reserved gaps of the first building block 26-49 and the second building block 26-51, and accurately fill the fine gaps between the first fitting groove 13 and the first building block 26-49 and between the second fitting groove 17 and the second building block 26-51, to form a double-sealing structure of "adhesive strip sealing + air bag filling", solve the problem of gaps caused by deformation of the traditional adhesive strip, especially have stronger adaptability to complex-shaped gaps, and greatly improve the overall sealing performance of the curtain wall.

[0047] Specifically, the releasing member 30 includes a sliding sleeve 30-1 slidably connected to one side of the cross fixed rod 28. One side of the sliding sleeve 30-1 is fixedly connected with the bent plate 27. A fifth spring 30-2 is fixedly connected to one side of an inner cavity of the sliding sleeve 30-1. One side of the fifth spring 30-2 is fixedly connected with the cross fixed rod 28. A limiting block 30-3 is fixedly connected to a surface of the cross fixed rod 28. A limiting groove 30-4 is arranged in the inner cavity of the sliding sleeve 30-1 and cooperates with the limiting block 30-3.

[0048] In the initial stage of the rotating process of the fixed rod 21, the cross fixed rod 28 is limited by the plugging plate 30-6 and is in a limited state, so as to avoid the cross fixed rod 28 from moving randomly and interfering with the rotation of the fixed rod 21. When the fixed rod 21 is rotated to a proper tightening degree, i.e., the compression amount of the sealing adhesive strip reaches a reasonable range, the fifth spring 30-2 is in action, drives the cross fixed rod 28 to move, and makes the cross fixed rod 28 penetrate through the rotating ring 23-7 to contact the fixed rod 21. The cooperation of the limiting block 30-3 and the limiting groove 30-4 not only provides a guide and support for the movement of the cross fixed rod 28, but also prevents the cross fixed rod 28 from rotating or deviating during the movement, so as to ensure that the cross fixed rod 28 can be accurately aligned with and clamped with the cross groove 29 of the fixed rod 21. Once the clamping is completed, the fixed rod 21 is firmly fixed and cannot continue to rotate, effectively avoiding the problem that the compression amount of the sealing adhesive strip is too large due to excessive rotation of the fixed rod 21, and ensuring the service life of the sealing adhesive strip and the reliability of the curtain wall sealing system.

[0049] Specifically, the second sliding groove 30-5 is arranged on one side of the bent plate 27, the inner cavity of the second sliding groove 30-5 is slidably connected with the blocking plate 30-6, the blocking plate 30-6 is provided with the guide groove 30-7 on one side, the inner cavity of the guide groove 30-7 is provided with the guide block 30-8, and the guide block 30-8 is fixedly connected with the movable plate 22, the sixth spring 30-9 is fixedly connected with the inner cavity of the second sliding groove 30-5 away from the blocking plate 30-6, and the side, close to the blocking plate 30-6, of the sixth spring 30-9 is fixedly connected with the blocking plate 30-6.

[0050] With the movement of the movable plate 22, when the guide block 30-8 is in contact with the guide groove 30-7, the blocking plate 30-6 is moved in the second sliding groove 30-5, the movement of the blocking plate 30-6 can release the limiting of the cross fixed rod 28, so that the cross fixed rod 28 is smoothly moved and in contact with the fixed rod 21 under the action of the fifth spring 30-2, the sixth spring 30-9 plays a role of buffering and resetting in this process, when the blocking plate 30-6 is released from the limiting, the sixth spring 30-9 can absorb part of the energy, avoid the excessive movement of the blocking plate 30-6 due to inertia, and provide power for the resetting of the blocking plate 30-6 when needed subsequently.
