Description

Technical Field

[0001] This application relates to the field of steel structure building technology, and in particular to an integrated wall panel and its installation method. Background Technology

[0002] Steel structure construction is a new type of building system. It typically includes a load-bearing structure composed of beams, columns, trusses, and other components supported by steel profiles, as well as an enclosure structure such as roofs, floors, and walls. Compared to traditional concrete buildings, steel structure buildings have higher strength and better earthquake resistance. Furthermore, their components can be prefabricated in factories and installed on-site, significantly shortening the construction cycle. Steel can be reused, greatly reducing construction waste and making it more environmentally friendly. Steel structure construction has gradually become a mainstream building technology and represents the future direction of architectural development.

[0003] After the main steel structure of a steel structure building is completed, wall panels are installed on the interior and exterior facades. Traditional installation methods generally use riveted exterior wall installation, I-beam clamp installation, or dry-hanging installation. These methods typically involve first installing a keel on the main steel structure, then installing fasteners for fixing the wall panels on the keel, and finally installing and fixing each wall panel to the keel one by one.

[0004] The aforementioned technologies require each wall panel to be installed and fixed individually, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0005] To improve construction efficiency, this application provides an integrated wall panel and its construction method.

[0006] On the one hand, this application provides an integrated wall panel, which adopts the following technical solution:

[0007] An integrated wall panel includes columns, a frame, inner wall panels, and outer wall panels. The frame is a rectangular frame with external fasteners on its exterior side. Two or more outer wall panels are connected to one side of the frame via the external fasteners. The frame has internal fasteners on its interior side, with two or more inner wall panels connected to the other side of the frame via the internal fasteners. The bottom of the frame has a plug, and the top of the frame has a slot corresponding to the plug. The frame also has connectors, and multiple frames are connected vertically in sequence via connectors. Both ends of the frame are connected to the columns.

[0008] By adopting the above technical solution, the columns are installed vertically on the construction site, the inner wall panels and outer wall panels are installed on both sides of the frame, and the frame is installed on the columns. The frames are installed sequentially in the vertical direction, and the inserts at the bottom of the upper frame are inserted into the slots of the lower frame. At the same time, connectors are used to connect two adjacent frames. The frame, inner wall panels, and outer wall panels are all prefabricated and assembled in the prefabrication yard. At the construction site, multiple frames are spliced ​​and installed from bottom to top. Therefore, it is not necessary to install each wall panel one by one on the construction site, shortening the construction cycle and improving construction efficiency.

[0009] Optionally, the external fastener includes an upper clip and a lower clip. The upper clip has an L-shaped cross-section, with its vertical section fixedly connected to the frame and its horizontal section extending away from the frame. A snap-fit ​​strip is provided at the end of the horizontal section of the upper clip facing the ground. The lower clip has a J-shaped cross-section, with one vertical section fixedly connected to the frame and the other vertical section extending vertically upward and directly opposite the snap-fit ​​strip. The edge of the exterior wall panel is provided with a snap-fit ​​groove. The snap-fit ​​strip snaps into the exterior wall panel through the snap-fit ​​groove at the top of the exterior wall panel, and the lower clip snaps into the exterior wall panel through the snap-fit ​​groove at the bottom of the exterior wall panel. The upper and lower clips of two adjacent frames in the vertical direction are fitted together.

[0010] By adopting the above technical solution, the edges of the exterior wall panel are surrounded by slots, and the exterior wall panel is fastened between the upper and lower clips through the slots, achieving the effect of facilitating the installation of the exterior wall panel on the frame; the horizontal sections of the upper and lower clips extend a certain distance, separating the exterior wall panel from the frame. The space between them reduces the infiltration of rainwater from the outside and reduces the impact of frame deformation on the exterior wall panel; the upper and lower clips of two adjacent frames in the vertical direction fit together. The upper clip is L-shaped, and when rainwater seeps in between the upper and lower clips, it is blocked by the upper clip and cannot continue to seep into the room, thus controlling the rainwater seepage path and achieving a waterproof effect; the lower clip is J-shaped, and the rainwater seeping along the exterior wall panel collects at the bottom of the lower clip and then drains away from both ends of the lower clip, preventing rainwater from seeping into the room and achieving a waterproof effect.

[0011] Optionally, the internal fastener includes an upper limit strip and a lower limit strip. The upper limit strip has an I-shaped cross-section and is horizontally connected to the frame facing the interior. The lower limit strip has an L-shaped cross-section. The interior wall panel is snapped between the upper limit strip and the lower limit strip. The upper limit strips and lower limit strips of two adjacent frames in the vertical direction are abutted together.

[0012] By adopting the above technical solution, the upper side of the inner wall panel is engaged with the upper limit strip, and the lower side is in contact with the lower small limit strip, thereby securing the inner wall panel between the upper and lower limit strips, achieving the effect of facilitating the installation of the inner wall panel on the frame.

[0013] Optionally, the frame is vertically provided with an external reinforcing strip on the side facing the outer wall panel. The cross-section of the external reinforcing strip is T-shaped, and two adjacent outer wall panels on the same frame are respectively snapped onto the two sides of the external reinforcing strip.

[0014] By adopting the above technical solution, a reinforcing strip is installed between two adjacent exterior wall panels on the same frame. The reinforcing strip has the effect of limiting the linearity of the gap between the two exterior wall panels, and at the same time, it can also serve to reinforce and support the exterior wall panels. In addition, when the exterior wall panel is damaged and needs to be replaced, the middle of the exterior wall panel can be actively broken open to facilitate the replacement of the exterior wall panel, which is convenient to operate.

[0015] Optionally, the frame is vertically provided with an inner reinforcing strip facing the interior. The cross-section of the inner reinforcing strip is I-shaped, and two adjacent interior wall panels on the same frame are respectively snapped into the two sides of the inner reinforcing strip.

[0016] By adopting the above technical solution, the internal reinforcing strips reinforce two adjacent inner wall panels on the same frame, thereby improving the structural stability of multiple inner wall panels on the frame.

[0017] Optionally, there is a gap between the outer wall panel and the frame, and the frame is provided with multiple support plates on the side facing the outer wall panel. The two ends of the support plates are respectively connected to the upper and lower sides of the frame, and the middle part of the support plate protrudes towards the outer wall panel and is connected to the outer wall panel.

[0018] By adopting the above technical solution, the middle part of the support plate is raised and connected to the outer wall panel, which plays a role in supporting and reinforcing the outer wall panel and reducing the shaking of the outer wall panel.

[0019] Optionally, a reinforcing rod is provided inside the frame, and the frame is filled with thermal insulation material.

[0020] By adopting the above technical solutions, reinforcing rods are installed inside the frame, which improves the structural stability of the frame. At the same time, the insulation material improves the building's thermal insulation performance, achieving the effect of energy saving.

[0021] Optionally, the column is provided with an L-shaped first corner bracket, and both sides of the frame are provided with L-shaped second corner brackets, with the first corner bracket and the second corner bracket connected together.

[0022] By adopting the above technical solution, when installing the frame, the second corner bracket on the frame is attached to the first corner bracket on the column, and the first corner bracket and the second corner bracket are connected and fixed, so as to facilitate the installation of the frame on the column.

[0023] Optionally, the connector includes a snap-fit ​​block, a lever block, a first piston rod, and a second piston rod. The lever block is slidably mounted on the frame and located on one side of the slot. One end of the lever block extends into the slot. The snap-fit ​​block is mounted on the top of the frame. A snap-fit ​​groove is formed at the bottom of the frame opposite to the snap-fit ​​block. A first oil cavity is formed inside the frame, and a second oil cavity is formed inside the snap-fit ​​block. The first oil cavity and the second oil cavity are connected. The first piston rod is slidably mounted in the first oil cavity, and its output end is connected to the lever block. A receiving groove is formed on the side of the snap-fit ​​block, and a snap-fit ​​plate is provided in the receiving groove. The bottom of the snap-fit ​​plate is hinged to the inner wall of the receiving groove. The second piston rod is slidably mounted in the second oil cavity, and its output end passes through the snap-fit ​​block and is hinged to the snap-fit ​​plate. A rectangular groove is formed on the side of the snap-fit ​​plate away from the snap-fit ​​block. A snap-fit ​​roller is slidably mounted on the snap-fit ​​plate and located in the rectangular groove. A spring is provided on the bottom side wall of the rectangular groove, and the spring causes the snap-fit ​​roller to always have a tendency to slide upward along the rectangular groove.

[0024] By adopting the above technical solution, during the installation of the frame, the insert block at the bottom of the upper frame is inserted into the slot at the top of the lower frame. At this time, the snap-fit ​​block on the lower frame is located in the snap-fit ​​groove of the upper frame. As the two frames approach each other, the insert block pushes the push block away from the slot. At this time, the first piston rod moves and pushes the hydraulic oil in the first oil chamber to move. The hydraulic oil flows into the second oil chamber and pushes the second piston rod to move. The second piston rod pushes the snap-fit ​​plate away from the snap-fit ​​block to rotate. At the same time, the upper frame pushes the snap-fit ​​roller to move downward along the rectangular groove. The gap between the snap-fit ​​roller and the upper frame tends to increase, allowing the upper frame to move closer to the lower frame. When the upper frame is driven to detach from the lower frame, the snap-fit ​​roller, under the action of the spring, abuts against the inner wall of the snap-fit ​​groove, and the gap between the snap-fit ​​roller and the inner wall of the snap-fit ​​groove tends to decrease, thereby fixing the upper frame to the lower frame and achieving the effect of facilitating the connection of two adjacent frames.

[0025] On the other hand, this application provides a method for installing an integrated wall panel, including the following steps:

[0026] S1: Prefabricate the columns, frames, interior wall panels, and exterior wall panels at the prefabrication yard, and install the interior wall panels and exterior wall panels on the frames; S2: Install the columns vertically at the construction site, and connect and install the frames between two columns; S3: Install multiple frames sequentially from bottom to top, insert the inserts at the bottom of the upper frame into the slots at the top of the lower frame, and fix adjacent frames together with connectors.

[0027] By adopting the above technical solutions, columns, frames, inner wall panels and outer wall panels are prefabricated in the prefabrication yard. At the same time, the inner wall panels and outer wall panels are installed on the frame in the prefabrication yard, so that the wall panels are not installed on the outer wall surface one by one on the construction site, thus shortening the construction cycle and improving construction efficiency.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The frame, interior wall panels, and exterior wall panels are all prefabricated and assembled in the prefabrication yard. At the construction site, multiple frames are spliced ​​and installed from bottom to top; thus, it is not necessary to install each wall panel one by one on the construction site, shortening the construction cycle and improving construction efficiency.

[0030] 2. The horizontal sections of the upper and lower retaining strips of the frame extend a certain distance to separate the exterior wall panel from the frame. The space between them reduces the infiltration of rainwater from the outside and also reduces the impact of frame deformation on the exterior wall panel.

[0031] 3. The upper and lower clips of two adjacent frames in the vertical direction are fitted together. The upper clip is L-shaped. When rainwater seeps in between the upper and lower clips, it is blocked by the upper clip and cannot continue to seep into the room, thus controlling the seepage path of rainwater and achieving a waterproof effect.

[0032] 4. The bottom retainer is J-shaped. Rainwater seeping along the exterior wall panel collects at the bottom of the bottom retainer, which can temporarily collect some of the rainwater before it drains away from both ends of the bottom retainer, preventing rainwater from seeping into the room and achieving a waterproof effect.

[0041] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0042] This application discloses an integrated wall panel, as shown in the embodiments below. Figure 1 An integrated wall panel includes columns 1, a frame 2, inner wall panels 3, and outer wall panels 4. The frame 2 is a rectangular frame made of welded square tubing. External fasteners are installed on the exterior-facing side of the frame 2, and the outer wall panels 4 are installed on the exterior-facing side of the frame 2 via these external fasteners. Internal fasteners are installed on the interior-facing side of the frame 2, and the interior wall panels 3 are installed on the interior-facing side of the frame 2 via these internal fasteners. In this embodiment, two interior wall panels 3 and two outer wall panels 4 are each installed on the frame 2. In other embodiments, multiple exterior wall panels 4 and multiple interior wall panels 3 are installed on the frame 2. Insert blocks 21 are welded to both ends of the bottom of the frame 2, and slots 22 are provided at both ends of the top of the frame 2. The slots 22 are adapted to the insert blocks 21. Multiple frames 2 are installed vertically from bottom to top, with the insert blocks 21 at the bottom of the upper frame 2 inserted into the slots 22 at the top of the lower frame 2. Connectors are also installed on the frame 2. When two frames 2 are connected vertically through the engagement of the insert 21 and the slot 22, the connectors fix the two frames 2 together. The column 1 is made of I-beam and is vertically fixed in the construction position. Two columns 1 are installed in parallel, and multiple frames 2 are installed between the two columns 1 in sequence.

[0043] In the prefabrication yard, columns 1, frames 2, inner wall panels 3, and outer wall panels 4 are prefabricated. Simultaneously, inner wall panels 3 and outer wall panels 4 are installed on frames 2. Columns 1 and frames 2 are then transported to the construction site. According to the site requirements, columns 1 are installed, and frames 2 are installed sequentially from bottom to top between two columns 1. During frame 2 installation, frames 2 are connected to columns 1, and the inserts 21 at the bottom of the upper frame 2 are inserted into the slots 22 at the top of the lower frame 2. This eliminates the need for individual wall panel installation and fixing on-site, shortening the construction cycle and improving efficiency. Depending on the design requirements of different steel structure buildings, columns 1, frames 2, inner wall panels 3, and outer wall panels 4 of different sizes can be prefabricated. The number of inner wall panels 3 and outer wall panels 4 installed on the same frame 2 can also be adjusted according to design requirements, making it widely applicable.

[0044] Reference Figure 1 An L-shaped first angle bracket 11 is installed on the column 1. The vertical section of the first angle bracket 11 is fixedly connected to the column 1. An L-shaped second angle bracket 27 is installed on both sides of the frame 2. The vertical section of the second angle bracket 27 is fixedly connected to the end face of the frame 2. The horizontal sections of the first angle bracket 11 and the second angle bracket 27 are perpendicular to each other and overlap. A waist-shaped hole is opened on the horizontal section of the first angle bracket 11 and the second angle bracket 27. The first angle bracket 11 and the second angle bracket 27 are fixedly connected by bolts.

[0045] Reference Figure 3 and Figure 4 A reinforcing rod 26 is installed at an angle inside the frame 2 to enhance its structural strength. The frame 2 is filled with thermal and sound insulation material (not shown in the diagram), which improves the thermal and sound insulation performance of the integrated wall panel, achieving energy conservation and emission reduction. Lifting lugs are installed on both ends of the frame 2, facilitating mechanical connection and lifting. A column base is installed at the insertion block 21 of the bottom frame 2, and the slot 22 of the top frame 2 is sealed.

[0046] Reference Figure 2 and Figure 3The external fasteners include an upper retaining strip 51 and a lower retaining strip 52. The upper retaining strip 51 is an L-shaped plate that is fixedly installed on the frame 2 along its length. The upper retaining strip 51 is located at the top of the outdoor-facing side of the frame 2. The vertical section of the upper retaining strip 51 is flush with and fixedly connected to the frame 2, while the horizontal section extends away from the frame 2. A rectangular retaining strip 53 is fixedly connected to the end of the horizontal section of the upper retaining strip 51 facing the ground. The lower retaining strip 52 is a J-shaped plate that is parallel to the upper retaining strip 51. One side of the lower retaining strip 52 is fixedly connected to the frame 2, with its opening facing upwards and its lower end extending beyond the frame 2. The end of the lower retaining strip 52 is vertically aligned with the retaining strip 53. The outer wall panel 4 has a groove 41 around its edge. The snap-fit ​​strip 53 snaps into the outer wall panel 4 through the groove 41 at the top of the outer wall panel 4, and the lower snap-fit ​​strip 52 snaps into the outer wall panel 4 through the groove 41 at the bottom of the outer wall panel 4. When the two frames 2 are connected in the vertical direction, the lower snap-fit ​​strip 52 on the upper frame 2 fits into the upper snap-fit ​​strip 51 on the lower frame 2.

[0047] By creating a groove 41 around the edge of the exterior wall panel 4, it is easy to snap the exterior wall panel 4 between the upper clip 51 and the lower clip 52, thus facilitating the installation of the exterior wall panel 4 onto the frame 2. The horizontal sections of both the upper clip 51 and the lower clip 52 extend away from the frame 2 by a distance. When the exterior wall panel 4 is installed between the upper clip 51 and the lower clip 52, there is a gap between the exterior wall panel 4 and the frame 2. This gap reduces the infiltration of outdoor rainwater into the room, and also prevents the frame 2 from directly contacting the exterior wall panel 4 when it deforms, reducing the impact of frame 2 deformation on the exterior wall panel 4. In rainy weather, rainwater seeps in through the gap between two adjacent exterior wall panels 4. When the rainwater seeps into the gap between the upper clip 51 and the lower clip 52, the lower clip 52 blocks the rainwater from further infiltrating into the room, achieving a waterproof effect. Meanwhile, the lower retaining strip 52 is J-shaped, and rainwater that seeps in along the outer wall panel 4 will collect at the bottom of the lower retaining strip 52 and then drain away from both ends of the lower retaining strip 52, resulting in good overall waterproofing.

[0048] Reference Figure 3An external reinforcing strip 23 is installed on the outdoor-facing side of the frame 2. The external reinforcing strip 23 is a T-shaped plate, with both ends connected to the two sides of the frame 2. The flanges of the external reinforcing strip 23 and the snap-fit ​​strip 53 are on the same vertical plane. When the exterior wall panel 4 is snapped between the upper snap-fit ​​strip 51 and the lower snap-fit ​​strip 52, the exterior wall panels 4 on both sides of the external reinforcing strip 23 are snapped with the flanges of the external reinforcing strip 23 through the snap-fit ​​groove 41. It should be noted that in this embodiment, there are two exterior wall panels 4, and the external reinforcing strip 23 is installed between the two exterior wall panels 4. In other embodiments, when there are multiple exterior wall panels 4, the number of external reinforcing strips 23 installed on the same frame 2 is one less than the number of exterior wall panels 4.

[0049] Reference Figure 2 The horizontal section of the upper retaining strip 51 and the horizontal end of the lower retaining strip 52 both extend away from the frame 2 by one distance. There is a gap between the outer wall panel 4 and the frame 2. Multiple support plates 25 are installed on the side of the frame 2 facing the outer wall panel 4. The two ends of the support plates 25 are fixedly connected to the upper and lower side frames of the frame 2, respectively. The middle part of the support plate 25 protrudes towards the outer wall panel 4 and abuts against the outer wall panel 4. Adhesive is applied at the position where the support plate 25 abuts against the outer wall panel 4, and the support plate 25 and the outer wall panel 4 are connected and fixed by adhesive.

[0050] The outer reinforcing strip 23 has its flanges interlocking with two exterior wall panels 4 on both sides. The outer reinforcing strip 23 serves a waterproof function, preventing water seepage onto the exterior wall panels 4. Simultaneously, the outer reinforcing strip 23 provides support to the exterior wall panels 4, limiting the shape of the gaps between the two panels and ensuring neat and aesthetically pleasing joints. The support plate 25 holds the exterior wall panels 4 firmly between the upper clamping strip 51 and the lower clamping strip 52, and is fixedly connected to the exterior wall panels 4. The support plate 25 reduces the swaying of the exterior wall panels 4, improving their stability.

[0051] When the exterior wall panel 4 is damaged and needs to be replaced, the damaged exterior wall panel 4 can be actively dismantled to facilitate replacement. At the same time, since there is a gap between the exterior wall panel 4 and the frame 2, dismantling the exterior wall panel 4 can, to some extent, avoid damage to the frame 2 and the thermal insulation and sound insulation materials inside the frame 2.

[0052] Reference Figure 4The internal fasteners include an upper limit strip 61 and a lower limit strip 62. The upper limit strip 61 has an I-shaped cross-section and is horizontally fixed to the side of the frame 2 facing the interior, located at the top of the side of the frame 2. The lower limit strip 62 has an L-shaped cross-section and is parallel to the upper limit strip 61, located at the bottom of the frame 2 and extending beyond it. The interior wall panel 3 is snapped between the upper limit strip 61 and the lower limit strip 62. When the two frames 2 are connected vertically, the horizontal section of the lower limit strip 62 of the upper frame 2 fits against the web of the upper limit strip 61 on the lower frame 2.

[0053] Reference Figure 4 An inner reinforcing strip 24 is vertically installed on the interior side of the frame 2. The cross-sectional shape of the inner reinforcing strip 24 is I-shaped. The upper end of the inner reinforcing strip 24 is fixedly connected to the upper frame of the frame 2 and the upper limit strip 61, and the lower end of the inner reinforcing strip 24 is fixedly connected to the lower frame of the frame 2 and the lower limit strip 62. The outer flange of the inner reinforcing strip 24 and the outer flange of the upper limit strip 61 are located on the same horizontal plane. The inner wall panels 3 on both sides of the inner reinforcing strip 24 are respectively snapped onto both sides of the inner reinforcing strip 24. It should be noted that in this embodiment, there are two inner wall panels 3, and the inner reinforcing strip 24 is installed between the two inner wall panels 3. In other embodiments, when there are multiple inner wall panels 3, the number of inner reinforcing strips 24 installed on the same frame 2 is one less than the number of inner wall panels 3.

[0054] The inner wall panel 3 is snapped onto the frame 2 by the upper limit strip 61 and the lower limit strip 62, which facilitates the installation of the inner wall panel 3. At the same time, an I-shaped inner reinforcing strip 24 is installed between the two inner wall panels 3 to reinforce and support the inner wall panels 3 and improve the structural stability of the inner wall panels 3.

[0055] Reference Figure 5 and Figure 6The connector includes a snap-fit ​​block 71, a lever block 72, a first piston rod 73, and a second piston rod 74. The frame 2 is a frame made of square tubes. Both ends of the two long sides of the frame 2 are solid. A groove is formed on the long side of the frame 2 near the slot 22, and the groove is connected to the slot 22. The lever block 72 is slidably mounted on the frame 2 and located in the groove. One end of the lever block 72 extends into the slot 22, and the end of the lever block 72 extending into the slot 22 is set at an angle. When the insert block 21 is inserted into the slot 22, the insert block 21 abuts against the angled surface of the lever block 72 and pushes the lever block 72 into the groove along the angled surface. A first oil cavity 75 is formed on the frame 2 and on one side of the groove. The first piston rod 73 is slidably mounted in the first oil cavity 75, and the end of the first piston rod 73 extends into the groove and is fixedly connected to the lever block 72. The snap-fit ​​block 71 is fixedly installed on the top of the frame 2. The snap-fit ​​block 71 is a rectangular block. A second oil cavity 76 is formed inside the snap-fit ​​block 71. An oil passage is formed between the first oil cavity 75 and the second oil cavity 76. Both the first oil cavity 75 and the second oil cavity 76 are filled with hydraulic oil. A snap-fit ​​groove 28 is formed at the bottom of the frame 2 opposite to the snap-fit ​​block 71, which is adapted to the snap-fit ​​block 71. A receiving groove 711 is formed on the side of the snap-fit ​​block 71. A snap-fit ​​plate 77 is installed on the snap-fit ​​block 71 and located in the receiving groove 711. The bottom of the snap-fit ​​plate 77 is hinged to the inner wall of the receiving groove 711. The second piston rod 74 is slidably installed in the second oil cavity 76, and the output end of the second piston rod 74 slides through the snap-fit ​​block 71 and is hinged to the snap-fit ​​plate 77. A rectangular groove 771 is formed on the side of the locking plate 77 opposite to the second piston rod 74. A locking roller 78 is slidably installed in the rectangular groove 771. The locking roller 78 is cylindrical, and its diameter is greater than the depth of the rectangular groove 771. Slider blocks are coaxially installed at both ends of the locking roller 78. Grooves are formed on both sides of the rectangular groove 771 along the length of the locking plate 77. The sliders on both sides of the locking roller 78 slide and engage in the grooves. A spring 79 is installed on the bottom side wall of the rectangular groove 771. One end of the spring 79 is connected to the locking plate 77, and the other end extends toward the locking roller 78. The spring 79 ensures that the locking roller 78 always has a tendency to slide upward along the rectangular groove 771. When the top of the locking plate 77 is rotated to be flush with the surface of the locking block 71, part of the locking roller 78 is outside the locking block 71.

[0056] A compression spring is also installed on the skeleton 2 and located in the slide groove. The compression spring is sleeved on the output shaft of the first piston rod 73. The compression spring causes the push block 72 to always tend to move toward the slot 22, so that the snap plate 77 is always located in the receiving groove 711 in the initial position.

[0057] In other embodiments, the fastener can also be a self-tapping screw. After the insert 21 of the upper frame 2 is fully inserted into the slot 22 of the lower frame 2, the frame 2 and the insert 21 are fixedly connected by the self-tapping screw.

[0058] When multiple frames 2 are installed sequentially from bottom to top on the column 1, the insert 21 of the upper frame 2 is inserted into the slot 22 of the lower frame 2. At this time, the snap-fit ​​block 71 on the lower frame 2 is inserted into the snap-fit ​​groove 28 on the upper frame 2. As the insert 21 is inserted, it abuts against the push block 72 and pushes the push block 72 to move into the slide groove. At this time, the first piston rod 73 pushes the hydraulic oil in the first oil chamber 75 into the second oil chamber 76. The hydraulic oil drives the second piston rod 74 to move, and the second piston rod 74 drives the snap-fit ​​plate 77 to rotate outward toward the snap-fit ​​block 71. The top of the snap-fit ​​plate 77 rotates until it is flush with the side wall of the snap-fit ​​block 71. At this time, the snap-fit ​​plate 77 abuts against the inner wall of the snap-fit ​​groove 28. The upper frame 2 is driven to move closer to the lower frame 2. At this time, the upper frame 2 pushes the snap-fit ​​roller 78 downward, and the gap between the snap-fit ​​roller 78 and the inner wall of the snap-fit ​​groove 28 tends to increase. After the two frames 2 are connected and installed in place, the two frames 2 are driven to separate. The upper frame 2 drives the snap-fit ​​roller 78 to slide upward. The gap between the snap-fit ​​roller 78 and the side wall of the snap-fit ​​groove 28 tends to decrease, thereby snapping the snap-fit ​​block 71 into the snap-fit ​​groove 28, so as to facilitate the fixation of the two adjacent frames 2.
