Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a node structure device for energy-saving retrofitting of glass curtain walls. Background Technology

[0002] With the rapid development of urban architecture, glass curtain walls have been widely used in various public buildings and high-rise buildings due to their transparency, aesthetics, and modern feel. However, with the increasing requirements for building energy conservation, the design of the node structure in the energy-saving renovation of existing glass curtain walls is often unreasonable, resulting in problems such as inconvenient installation, poor sealing performance, and weak adaptability, which affect the effectiveness and efficiency of energy-saving renovation.

[0003] Current glass curtain wall technologies mostly employ a hook-and-loop installation method to reposition the glass curtain wall. However, this hook-and-loop method cannot effectively guarantee the airtightness between the glass curtain wall and the curtain wall windows, failing to ensure a tight seal. It necessitates the installation of additional frame panels for joint sealing, resulting in poor sealing and leading to heat transfer and air infiltration, thus impacting the energy-saving performance of the glass curtain wall. Furthermore, current ventilation technologies rely on opening the entire glass curtain wall for indoor and outdoor ventilation. Prolonged open / closed operation can compromise the airtightness, leading to heat transfer and air infiltration over extended periods, again affecting energy efficiency. Therefore, there is an urgent need for a glass curtain wall that provides a tight seal without requiring the curtain wall to be opened for ventilation. This necessitates further improvements to the joint structure of the glass curtain wall. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution:

[0005] A node structure device for energy-saving renovation of glass curtain walls includes vertical poles and horizontal poles. The horizontal poles are slidably installed between adjacent vertical poles. A receiving mechanism is slidably installed on the back of the horizontal pole and sleeved around the bottom periphery of the glass curtain wall. Adjustment mechanisms are provided on both sides of the horizontal pole to adjust the position of the receiving mechanism and securely seal the glass curtain wall to the vertical poles and horizontal poles. A ventilation mechanism is detachably installed on the horizontal pole, with one end of the ventilation mechanism penetrating through the glass curtain wall and the receiving mechanism. A blocking mechanism for rotating and sealing the ventilation channel is provided on the inner wall of the ventilation mechanism near the front. The windward side of the blocking mechanism has an arc-shaped structure. An air blowing mechanism that rotates with the wind is rotatably installed on the inner wall of the ventilation mechanism.

[0006] As an improvement to the above technical solution, the receiving mechanism includes a bearing plate and a positioning block. The back of the crossbar is provided with a groove for the bearing plate to slide. The positioning block is fixedly connected to both sides of the bearing plate. The inner walls of the groove are provided with sliding grooves for the positioning block to slide. The top surface of the bearing plate is provided with a placement groove that fits around the bottom edge of the glass curtain wall.

[0007] As an improvement to the above technical solution, the adjustment mechanism includes an adjustment screw and a second spring. The adjustment screw is threadedly connected to the positioning block. One end of the adjustment screw is rotatably connected in the slide groove, and the other end of the adjustment screw passes through the crossbar and is rotatably connected to the crossbar. The second spring is fixedly connected between the slide groove and the positioning block and is sleeved around the adjustment screw.

[0008] As an improvement to the above technical solution, the ventilation mechanism includes a ventilation pipe, a positioning ring, and an adjusting ring. The crossbar has an insertion hole for the ventilation pipe to be inserted, and the insertion hole passes through the glass curtain wall and the supporting plate. The positioning ring is fixedly connected to the periphery of the ventilation pipe. A retaining ring that engages with the positioning ring is fixedly connected to the crossbar. The adjusting ring is rotatably disposed on the periphery of the end of the ventilation pipe. An intermittent stop mechanism is provided between the periphery of the ventilation pipe and the adjusting ring.

[0009] As an improvement to the above technical solution, the intermittent stop mechanism includes a limit rod, a first spring, and a positioning bead. The ventilation pipe has a slot for the limit rod to slide around its periphery. The slot is equidistantly arranged along the circumference of the ventilation pipe. The first spring is fixedly connected between the bottom of the slot and the adjacent limit rod. The positioning bead is fixedly connected to the limit rod. The inner wall of the adjusting ring has a positioning groove for the positioning bead to be inserted.

[0010] As an improvement to the above technical solution, a lead screw is rotatably installed at the axis of the inner wall of the ventilation pipe. One end of the lead screw is rotatably connected to a second bracket, which is fixedly connected to the inner wall of the ventilation pipe. The other end of the lead screw is fixedly connected to a first bracket, which is fixedly connected to the inner wall of the adjusting ring. The air blowing mechanism is rotatably installed around the lead screw.

[0011] As an improvement to the above technical solution, a frustum-shaped gas diffuser and a gas concentrator are fitted around the lead screw. The gas diffuser is located between the gas concentrator and the second support. The gas diffuser is rotatably mounted around the lead screw via a bearing. The gas concentrator is slidably mounted on the inner wall of the ventilation pipe and is fitted around and passes through the outer periphery of the gas diffuser. A connecting rod is fixedly connected to one side of the gas concentrator, and a collar is fixedly connected to one end of the connecting rod. The collar is threadedly connected to the lead screw.

[0012] As an improvement to the above technical solution, the blocking mechanism is provided in multiple sets. The blocking mechanism includes a blocking plate and a fixing plate. Both the blocking plate and the fixing plate are fan-shaped arc plates. The outer periphery of the fixing plate is fixedly connected to the inner wall of the ventilation pipe. The fixing plate is rotatably connected to the outer periphery of the lead screw through a bearing. The blocking plate and the fixing plate are rotatably connected and are in a close fit with each other. The outer periphery of the blocking plate is rotatably connected to the inner wall of the ventilation pipe. The blocking plate is fixedly connected to the outer periphery of the lead screw. The space enclosed by the adjacent fixing plates is a ventilation space.

[0013] As an improvement to the above technical solution, the air blowing mechanism includes a first fan blade and a second fan blade. Both the first fan blade and the second fan blade are rotatably connected to the outer periphery of the lead screw through bearings. The first fan blade is disposed between the second bracket and the air diffuser, and the second fan blade is disposed near the baffle plate.

[0014] As an improvement to the above technical solution, sliding blocks are fixedly connected to both sides of the crossbar, and a positioning screw is threaded between the sliding block and the upright. A square-structured limiting block is fixedly connected to one end of the positioning screw, and a limiting groove is opened on one side of the sliding block, which is slidably sleeved around the limiting block.

[0015] The beneficial effects of this invention are:

[0016] By incorporating and adjusting mechanisms, a tight seal between the glass curtain wall and the vertical and horizontal bars is ensured, preventing heat transfer and air infiltration. This guarantees effective sealing of the glass curtain wall's edge nodes and enhances its energy-saving effect. Furthermore, the ventilation and air-blowing mechanisms enable effective indoor and outdoor ventilation without opening the glass curtain wall, preventing a decrease in sealing performance due to prolonged open / closed operation. Additionally, the blocking mechanism seals the ventilation channels when ventilation is not required, and its curved windward surface reduces noise when ventilation is not needed. Therefore, this invention offers both energy-saving and noise-reduction benefits. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Please refer to Figures 1-14 As shown, the present invention provides a node structure device for energy-saving renovation of glass curtain walls, including a vertical pole 1 and a horizontal pole 2, wherein the horizontal pole 2 is slidably arranged between adjacent vertical poles 1.

[0034] A receiving mechanism is slidably installed on the back of the horizontal bar 2 and sleeved around the bottom edge of the glass curtain wall. Adjustment mechanisms are provided on both sides of the horizontal bar 2 to adjust the position of the receiving mechanism and secure the glass curtain wall to the vertical bar 1 and the horizontal bar 2.

[0035] A ventilation mechanism is detachably installed on the crossbar 2, with one end of the ventilation mechanism passing through the glass curtain wall and the housing mechanism;

[0036] The ventilation mechanism has a rotating sealed ventilation channel blocking mechanism on the inner wall near the front. The windward side of the blocking mechanism has an arc-shaped structure. The ventilation mechanism also has a rotating air blowing mechanism on the inner wall that rotates with the wind.

[0037] In this case, the uprights 1 and horizontal bars 2 form a support frame for installing the glass curtain wall. The horizontal bars 2 are slidably installed between adjacent uprights 1, which facilitates changing the height of the horizontal bars 2 to accommodate different glass curtain walls. A receiving mechanism for the glass curtain wall is slidably installed on the back of the horizontal bars 2, allowing the glass curtain wall to be placed on the receiving mechanism for pre-fixation. This avoids workers constantly having to lift the glass curtain wall during installation, reducing labor intensity, installation difficulty, and improving construction efficiency. Adjustment mechanisms are provided on both sides of the horizontal bars 2 to adjust the position of the receiving mechanism, ensuring that the edges of the glass curtain wall tightly abut against the uprights 1 and horizontal bars 2, achieving a seal between the glass curtain wall, uprights 1, and horizontal bars 2, ensuring airtightness and preventing air leakage. The inherent insulation effect of the glass curtain wall, combined with the enhanced sealing, reduces heat transfer and air infiltration, enhancing the energy-saving effect of the glass curtain wall and making installation convenient.

[0038] Supplement: The overall size of the glass curtain wall is larger than the size of the so-called curtain wall window between adjacent vertical poles 1 and horizontal poles 2. This ensures that the glass curtain wall is tightly and securely sealed to vertical poles 1 and horizontal poles 2 during installation, guaranteeing a good sealing effect.

[0039] The ventilation mechanism is installed on the crossbar 2 to facilitate indoor and outdoor ventilation. The ventilation mechanism runs through the glass curtain wall and the housing mechanism, which can confine the glass curtain wall to the housing mechanism and prevent the glass curtain wall from shifting or swaying. A blocking mechanism is installed inside the ventilation mechanism near the interior. By rotating the blocking mechanism, the ventilation channel can be sealed. Therefore, the ventilation can be turned off when ventilation is not needed. The windward side of the blocking mechanism is set with an arc structure. When the ventilation is not in the ventilation state, the arc structure can disperse the gas blown into the ventilation channel to reduce noise.

[0040] Additional explanation: Multiple ventilation mechanisms are provided. One end passes through the glass curtain wall and the housing mechanism, communicating with the outside, while the other end passes through the front of the horizontal bar 2, communicating with the interior. Although the overall width of the horizontal bar 2 is limited, the multiple ventilation mechanisms still function effectively. For example, the heat dissipation holes used in machinery, when blown by a fan, can achieve heat dissipation. In this invention, multiple ventilation mechanisms are used in conjunction with the air blowing mechanism to achieve effective indoor and outdoor ventilation, ensuring the ventilation effect. Furthermore, in existing technologies, considering safety issues, the opening angle of the glass curtain wall is limited, thus limiting the ventilation area. Therefore, the ventilation method in this invention can meet the ventilation requirements and achieve effective ventilation.

[0041] The ventilation system is designed to be detachable, allowing for easy disassembly and replacement after prolonged use. It also facilitates the cleaning of the internal ventilation channels, ensuring its lifespan and enabling indoor and outdoor ventilation without opening the glass curtain wall.

[0042] By incorporating and adjusting mechanisms, a tight seal between the glass curtain wall and the vertical poles 1 and horizontal poles 2 is ensured, preventing heat transfer and air infiltration, guaranteeing effective sealing of the glass curtain wall edge nodes, and enhancing the energy-saving effect of the glass curtain wall. Furthermore, by incorporating ventilation and air-blowing mechanisms, effective indoor and outdoor ventilation can be achieved without opening the glass curtain wall, preventing a decrease in sealing performance due to prolonged open or closed operation. Simultaneously, by incorporating a blocking mechanism, the ventilation channel can be sealed when ventilation is not required, and the windward surface of the blocking mechanism has an arc-shaped structure, which reduces noise when ventilation is not needed. Therefore, this invention has both energy-saving and noise-reducing effects.

[0043] like Figure 4 , Figure 5 and Figure 8 As shown, the receiving mechanism includes a bearing plate 4 and a positioning block 41. A groove 24 for the bearing plate 4 to slide is provided on the back of the crossbar 2. The positioning block 41 is fixedly connected to both sides of the bearing plate 4. Slide grooves 25 for the positioning block 41 to slide are provided on both sides of the inner wall of the groove 24. A placement groove 42 for the bottom periphery of the glass curtain wall is provided on the top surface of the bearing plate 4.

[0044] The sliding arrangement of the support plate 4 facilitates its movement, allowing the placement groove 42 to be moved outward. This makes it easier to insert the bottom of the glass curtain wall into the placement groove 42, providing pre-fixed support for the glass curtain wall and preventing it from always being in a raised state, thus facilitating the installation of the glass curtain wall.

[0045] Among them, such as Figure 8As shown, a socket groove 43 is provided on the bottom surface of the bearing plate 4. The socket groove 43 is fitted around the top edge of the glass curtain wall. When the bottom end of the glass curtain wall is inserted into the placement groove 42, another set of horizontal bars 2 is slid so that the socket groove 43 is fitted onto the top edge of the glass curtain wall. By limiting the bottom and top edges of the glass curtain wall, the sealing at the joint of the glass curtain wall, the vertical bar 1 and the horizontal bar 2 are ensured, and the sealing effect is improved.

[0046] like Figure 4 and Figure 8 As shown, the adjustment mechanism includes an adjustment screw 411 and a second spring 412. The adjustment screw 411 is threadedly connected to the positioning block 41. One end of the adjustment screw 411 is rotatably connected in the slide groove 25, and the other end of the adjustment screw 411 passes through the crossbar 2. The adjustment screw 411 is rotatably connected to the crossbar 2. The second spring 412 is fixedly connected between the slide groove 25 and the positioning block 41, and the second spring 412 is sleeved around the adjustment screw 411.

[0047] By turning the adjusting screw 411, the positioning block 41 can be driven to slide within the slide groove 25, pressing against the second spring 412. The positioning block 41 drives the bearing plate 4 to move, causing the placement groove 42 on the bearing plate 4 to protrude, which facilitates the installation of the glass curtain wall. After the glass curtain wall is placed, turning the adjusting screw 411 again can drive the positioning block 41 to return. The positioning block 41 drives the bearing plate 4 to move, and the bearing plate 4 drives the glass curtain wall to move, so that the edges of the glass curtain wall are tightly sealed to the uprights 1 and the crossbars 2, achieving a seal at the joint.

[0048] Supplement: The purpose of the second spring 412 is to prevent the adjusting screw 411 from becoming loose due to unscrewing. When the threads between the adjusting screw 411 and the positioning block 41 become loose due to long-term use, the second spring 412 will still exert a squeezing effect on the positioning block 41, ensuring the sealing between the glass curtain wall and the vertical pole 1 and horizontal pole 2, thus achieving the purpose of secondary reinforcement.

[0049] like Figure 2 , Figure 5 , Figure 8 and Figure 9 As shown, the ventilation mechanism includes a ventilation pipe 3, a positioning ring 31, and an adjusting ring 32. A socket 21 for inserting the ventilation pipe 3 is provided on the crossbar 2. The socket 21 passes through the glass curtain wall and the supporting plate 4. The positioning ring 31 is fixedly connected to the outside of the ventilation pipe 3. A retaining ring 22 that engages with the positioning ring 31 is fixedly connected to the crossbar 2. The adjusting ring 32 is rotatably set on the outside of the end of the ventilation pipe 3. An intermittent stop mechanism is provided between the outside of the ventilation pipe 3 and the adjusting ring 32.

[0050] The ventilation duct 3 is designed to facilitate indoor and outdoor ventilation without opening the glass curtain wall. A positioning ring 31 is provided around the ventilation duct 3 to engage with the retaining ring 22. After the glass curtain wall is placed into the placement groove 42 on the support plate 4, the insertion hole 21 is connected by sliding the glass curtain wall. At this time, it is easy to insert the ventilation duct 3 into the insertion hole 21. The outer radius of the ventilation duct 3 is the same as the inner radius of the insertion hole 21, which can achieve a seal after insertion and seal the insertion hole 21. Then, the positioning ring 31 is engaged with the retaining ring 22 to fix the ventilation duct 3.

[0051] Among them, ventilation pipe 3 can not only provide ventilation, but also fix the glass curtain wall to prevent it from shifting.

[0052] like Figure 12 , Figure 13 and Figure 14 As shown, the intermittent stop mechanism includes a limit rod 331, a first spring 332, and a positioning bead 333. The ventilation pipe 3 has a slot 33 for the limit rod 331 to slide on its outer periphery. The slot 33 is equidistantly arranged along the outer circumference of the ventilation pipe 3. The first spring 332 is fixedly connected to the bottom of the slot 33 and the adjacent limit rod 331. The positioning bead 333 is fixedly connected to the limit rod 331. The inner wall of the adjusting ring 32 has a positioning groove 322 for the positioning bead 333 to be inserted into.

[0053] By setting the positioning bead 333, rotating the adjusting ring 32 can press the positioning bead 333, which can retract under the action of the first spring 332. After moving to communicate with the positioning groove 322, the adjusting ring 32 can be positioned, realizing the intermittent rotation positioning of the adjusting ring 32.

[0054] like Figure 9 and Figure 10 As shown, a lead screw 5 is rotatably installed at the axis of the inner wall of the ventilation pipe 3. One end of the lead screw 5 is rotatably connected to a second bracket 51, which is fixedly connected to the inner wall of the ventilation pipe 3. The other end of the lead screw 5 is fixedly connected to a first bracket 321, which is fixedly connected to the inner wall of the adjusting ring 32. The air blowing mechanism is rotatably installed around the lead screw 5.

[0055] A frustum-shaped diffuser hood 54 and a concentrator hood 56 are fitted around the lead screw 5. The diffuser hood 54 is located between the concentrator hood 56 and the second support 51. The diffuser hood 54 is rotatably mounted around the lead screw 5 via a bearing. The concentrator hood 56 is slidably mounted on the inner wall of the ventilation pipe 3 and is fitted around and passes through the diffuser hood 54. A connecting rod 57 is fixedly connected to one side of the concentrator hood 56. A collar 55 is fixedly connected to one end of the connecting rod 57. The collar 55 is threadedly connected to the lead screw 5.

[0056] By setting the lead screw 5, rotating the adjusting ring 32 can drive the first support 321 to rotate, and the first support 321 drives the lead screw 5 to rotate. Under the support of the first support 321 and the second support 51, the lead screw 5 can maintain stability. The rotation of the lead screw 5 can drive the collar 55 to move around the lead screw 5. The collar 55 drives the connecting rod 57 to move, and the connecting rod 57 drives the gas-gathering hood 56 to move, thereby changing the position of the gas-gathering hood 56 and exchanging the positions of the gas-gathering hood 56 and the gas-dispersing hood 54, changing from gas dispersion first and then gas gathering to gas gathering first and then gas dispersing.

[0057] Additional information: Screw 5 is corrosion-resistant and will not rust even when wetted by rainwater. It can be made of titanium alloy, which has strong corrosion resistance and extends its service life.

[0058] like Figure 10 and Figure 11 As shown, the blocking mechanism is provided in multiple sets. The blocking mechanism includes a blocking plate 58 and a fixing plate 59. Both the blocking plate 58 and the fixing plate 59 are fan-shaped arc plates. The outer periphery of the fixing plate 59 is fixedly connected to the inner wall of the ventilation pipe 3. The fixing plate 59 is rotatably connected to the outer periphery of the lead screw 5 through a bearing. The blocking plate 58 and the fixing plate 59 are rotatably connected and are in a close fit with each other. The outer periphery of the blocking plate 58 is rotatably connected to the inner wall of the ventilation pipe 3. The blocking plate 58 is fixedly connected to the outer periphery of the lead screw 5. The space enclosed by the adjacent fixing plates 59 is the ventilation space.

[0059] With the setting of the baffle plate 58 and the fixed plate 59, the baffle plate 58 and the fixed plate 59 are connected in a close-fitting rotational manner, and the adjacent fixed plates 59 form a ventilation space. When ventilation is needed, the rotation of the screw 5 can drive the baffle plate 58 to rotate, so that the baffle plate 58 rotates in the ventilation pipe 3, thereby allowing the baffle plate 58 to rotate to the point where it coincides with the fixed plate 59, so that the gas can pass through the ventilation space and achieve indoor and outdoor ventilation. When ventilation is not needed, the rotation of the baffle plate 58 can block the ventilation space and prevent air convection from the ventilation space.

[0060] When ventilation is needed, the rotation of the lead screw 5 causes the baffle plate 58 to rotate, and at the same time, the air-gathering hood 56 also shifts. The air entering the ventilation duct 3 first passes through the air-diffusing hood 54 and then through the air-gathering hood 56. After passing through the air-gathering hood 56, it enters the room through the ventilation space. The air-gathering can accelerate the airflow and increase the air velocity, thereby accelerating air convection and improving ventilation efficiency. When ventilation is not needed, the rotation of the lead screw 5 causes the baffle plate 58 to block the ventilation space. At this time, the air entering the ventilation duct 3 first passes through the air-gathering hood 56 and then through the air-diffusing hood 54. The process of the air-diffusing hood 54 dispersing air around the air box can reduce some noise and has a noise reduction effect. Therefore, by changing the position of the air-gathering hood 56, noise generation can be reduced when ventilation is not needed.

[0061] Among them, such as Figure 10 As shown, both the air-gathering hood 56 and the air-diffusing hood 54 are frustum-shaped structures. The windward side of the air-diffusing hood 54 is the short side, which diffuses air in all directions, thus reducing noise. The windward side of the air-gathering hood 56 is the long side, and the radius of the inscribed circle of the short side of the air-gathering hood 56 is larger than the radius of the circumscribed circle of the long side of the air-diffusing hood 54, so that the air-gathering hood 56 can pass through the air-diffusing hood 54.

[0062] like Figure 10 As shown, the air blowing mechanism includes a first blade 52 and a second blade 53. Both the first blade 52 and the second blade 53 are rotatably connected to the outer periphery of the lead screw 5 via bearings. The first blade 52 is disposed between the second bracket 51 and the air diffuser 54, and the second blade 53 is disposed near the baffle plate 58.

[0063] With the arrangement of the first blade 52 and the second blade 53, both of which are rotatably mounted on the outer periphery of the lead screw 5 via bearings, when outdoor wind blows into the ventilation duct 3, it can cause the first blade 52 and the second blade 53 to rotate. The rotation of the first blade 52 and the second blade 53 can blow air into the room, causing the gas to flow into the room and achieving a ventilation effect. In the ventilation state, after the air is gathered, it rushes towards the second blade 53, which can accelerate the rotation speed of the second blade 53 and increase the air flow rate. In the non-ventilation state, after the air is dispersed, it rushes towards the second blade 53, which can reduce the rotation speed of the second blade 53. On the one hand, it reduces the noise generated when blowing air, and on the other hand, it reduces the air flow rate to prevent a large impact load on the baffle plate 58.

[0064] Supplement: The first blade 52 and the second blade 53 rotate by wind and can be connected to an external power system to achieve wind power generation. A power-conducting sleeve is installed around the ventilation duct 3, and the ventilation duct 3 is then connected to the socket 21 to connect to the wind power generation system. This wind power generation system generates current through the rotation of the first blade 52 and the second blade 53. This type of power generation system is existing technology, and its structure will not be described in detail. Alternatively, magnetic power generation can be used. Magnetic rods are installed at the ends of the first blade 52 and the second blade 53, and magnetic plates are installed on both sides inside the ventilation duct 3. The magnetic rods rotate within the magnetic power generation space enclosed by the magnetic plates. This power generation method is an earlier method, so generating electricity using the rotation of the first blade 52 and the second blade 53 is feasible.

[0065] like Figure 5 , Figure 6 and Figure 7As shown, sliding blocks 23 are fixedly connected to both sides of the crossbar 2. A positioning screw 11 is threaded between the sliding block 23 and the upright 1. A square-structured limiting block 111 is fixedly connected to one end of the positioning screw 11. A limiting groove 231 is opened on one side of the sliding block 23, which is slidably sleeved around the limiting block 111.

[0066] The positioning screw 11 facilitates the fixing of the crossbar 2 between adjacent uprights 1. The limiting block 111 allows the crossbar 2 to be pre-fixed when another set of uprights 1 and crossbar 2 needs to be connected. By sliding the crossbar 2, the limiting groove 231 on a set of sliding blocks 23 on the crossbar 2 is fitted around the outer edge of the previous set of limiting blocks 111, thus completing the pre-fixation of the crossbar 2. Then, the positioning screw 11 is used to fix the other set of sliding blocks 23, achieving a neat and orderly arrangement of the crossbar 2.

[0067] Additional information: After the horizontal bars 2 are neatly arranged, screws can be used to fix the limiting block 111 and the sliding block 23 together for reinforcement. The installation is convenient, and only one set of horizontal bars 2 needs to be installed. It is urgent to ensure the neat arrangement of the horizontal bars 2.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
