Description

Technical Field

[0001] This invention belongs to the technical field of curtain wall systems, and in particular relates to a large-span double-column unit curtain wall system and its installation and construction method. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building. It hangs like a curtain and is a lightweight wall structure commonly used in modern large and high-rise buildings for decorative purposes. To facilitate installation, curtain walls need to be unitized for faster installation. During the installation of curtain wall units, it is generally necessary to connect the installation structure to the load-bearing structure of the wall, such as columns. Therefore, a large-span, double-column unitized curtain wall system is required.

[0003] In existing technologies, curtain wall units are generally lifted to the installation position using lifting equipment. However, the existing installation method not only requires lifting the curtain wall one by one to the appropriate height, which wastes a lot of time and affects construction efficiency, but also requires adequate protection measures for the curtain wall during the lifting process when installing large-span curtain wall units, in order to avoid damage to the curtain wall caused by collisions with the building during the lifting process.

[0004] A search revealed that Chinese patent application number 2021115708978 discloses a large-span double-column unitized curtain wall system. This system comprises several large-span double-column curtain wall units, each consisting of left and right continuous-height small-section columns, a top horizontal beam, a middle horizontal beam, a bottom horizontal beam, left and right inter-story short columns, inter-story glass, and viewing glass. The left and right inter-story short columns and the left and right continuous-height small-section columns form a double-column structure. However, the construction efficiency of this curtain wall system is relatively low. Summary of the Invention

[0005] 1. The problem to be solved

[0006] The purpose of this invention is to provide a large-span double-column unitized curtain wall system and its installation and construction method, so as to solve the technical problems of complex construction operation, low construction efficiency and inconvenience of transportation in existing large-span double-column unitized curtain wall structures.

[0007] 2. Technical Solution

[0008] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0009] The present invention provides a large-span double-column unitized curtain wall system, comprising:

[0010] Two columns spaced apart;

[0011] Two mounting components are installed on one of the columns respectively and are used to fix the curtain wall unit.

[0012] Two support components are connected between the two mounting components and the two columns, respectively, to support and position the mounting components;

[0013] A connecting component is installed at one end of two mounting components that are close to each other, and is used to connect the mounting components. The connecting component includes two connecting brackets and a movable guide. The two connecting brackets are respectively rotatably installed at one end of the two mounting components and can slide relatively linearly along the movable guide.

[0014] Furthermore, the movable guide includes a hollow tube and a sleeve. There are two hollow tubes, which are arranged parallel to each other vertically and pass through the two connecting frames. Both ends of each hollow tube are slidably disposed in a sleeve, and each sleeve is slidably installed on the corresponding connecting frame.

[0015] Furthermore, both ends of the hollow tube are provided with sealing rings, and the hollow tube is connected to the negative pressure equipment through a one-way sealing assembly; the one-way sealing assembly includes a connecting pipe and a one-way valve, wherein the two ends of the connecting pipe are respectively connected to the two hollow tubes, and the one-way valve is installed on the connecting pipe and connected to the connecting pipe.

[0016] Furthermore, each sleeve has a limiting plate on its inner side to prevent the inner side of the sleeve from passing through the connecting frame, and the outer sides of the two sleeves on the same connecting frame are connected by a fixing plate; the connecting frame is a transverse U-shaped frame structure, which is rotatably fitted onto the outside of one end of the mounting assembly.

[0017] Furthermore, the support component includes:

[0018] A ring-shaped plate that can be rotatably mounted on a column;

[0019] The first bracket has one end fixedly mounted on the annular plate, and the other end is detachably and rotatably connected to the connecting frame.

[0020] The second bracket has one end fixedly mounted on the ring plate, and the other end detachably and rotatably connected to the side of the mounting assembly away from the connecting frame.

[0021] Furthermore, the annular plate has two parts, upper and lower, which are rotatably connected to the connecting seat on the column. The first bracket and the second bracket are rotatably connected to the upper and lower ends of the mounting assembly. The first bracket, the second bracket, and the mounting assembly surround each other to form a triangular prism structure.

[0022] Furthermore, the connecting frame is provided with a connecting column, and the free end of the first bracket is correspondingly machined with a notch that engages and rotates with the connecting column; the end of the mounting component away from the connecting frame is machined with a connecting hole, and the free end of the second bracket is correspondingly machined with a round hole, so that the second bracket and the mounting component can be rotatably connected through a connecting shaft.

[0023] Furthermore, the mounting assembly includes a mounting frame with a support plate on it. A connecting rod is mounted through the support plate, and the outer side of the connecting rod is threaded. A threaded hole matching the aforementioned thread is opened on the side wall of the column.

[0024] The present invention discloses an installation and construction method for a large-span double-column unitized curtain wall system, comprising the following steps:

[0025] Step 1: Connect the two mounting components using the connecting assembly, causing the mounting components to rotate relative to the connecting frame, thereby folding the two mounting components for easy transport to the construction site;

[0026] Step 2: Install and fix the curtain wall unit onto the mounting assembly;

[0027] Step 3: Install the mounting components onto the corresponding columns using the support components. During the installation process, the mounting components and the connecting frame rotate relative to each other so that the mounting components are unfolded to 180°.

[0028] Furthermore, the specific installation process is as follows:

[0029] Connect one end of the mounting component to the second bracket, and then rotate the first bracket to engage with the connecting post on the connecting frame;

[0030] Rotate the first and second brackets to extend the two mounting components to 180°;

[0031] Connect the one-way sealing assembly and the negative pressure device, turn on the switch of the negative pressure device, and through the one-way sealing assembly and the sealing ring, extract the gas from the hollow tube and the sleeve, so that the two sleeves at both ends of the hollow tube come closer to each other, and thus bring the two connecting brackets closer to each other, preventing the two mounting components from rotating again.

[0032] Push the connecting rod so that it enters the threaded hole, and rotate the connecting rod to further secure the mounting bracket assembly to the column.

[0033] 3. Beneficial effects

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] (1) The present invention connects two installation components through a connecting component. On the one hand, the two connecting frames of the connecting component are respectively rotatably installed at one end of the two installation components, thus enabling the large-span curtain wall unit to be folded for easy transportation. When the curtain wall is installed on the construction site, the two installation components can be unfolded and driven to move closer to each other through the two connecting frames to prevent relative rotation between the installation components after installation, thus ensuring the stability of the curtain wall installation. On the other hand, the curtain wall system of the present invention can be installed simultaneously on each floor without the need for lifting equipment to lift the curtain wall units one by one, which greatly improves the installation efficiency of the curtain wall units.

[0036] (2) The present invention further optimizes the structure of the connecting components, especially by designing the movable guide as a telescopic sleeve connection structure, and by using the cooperation of the negative pressure device and the one-way sealing component to realize the relative movement of the sleeve and the hollow tube, thereby facilitating the two installation components to approach each other, and also helping to ensure the stability of the installation components after installation, and preventing relative rotation between the two installation components.

[0037] (3) The present invention can make preliminary connection and positioning between the installation component and the column by setting the support component. At the same time, the installation component can be unfolded by rotating the first bracket and the second bracket. Finally, the installation frame and the column can be fixedly connected by the connecting rod. The joint cooperation of the support component, the installation component and the connecting component can effectively ensure the stability of the installation of the large span curtain wall, and the operation is relatively simple.

Detailed Implementation

[0046] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] Combination Figure 1 In one embodiment of the present invention, a large-span double-column unitized curtain wall system includes:

[0049] Two columns 1 are spaced apart. The columns are pre-embedded or installed in the building during construction for subsequent installation of the curtain wall.

[0050] Two mounting components are provided, each corresponding to one of the columns 1, for installing and fixing the curtain wall unit. In this embodiment of the invention, the mounting components include a mounting frame 5, which has multiple mounting columns 6, through which the curtain wall unit is fixed to the mounting frame 5. It should be noted that the connection method between the curtain wall unit and the mounting frame 5 is not limited to the above structure; any method that can achieve a fixed connection of the curtain wall unit is acceptable. Therefore, any existing curtain wall fixing method can be used, such as a magnetic adsorption connection method.

[0051] A connecting component, installed at the ends of two mounting components that are close to each other, is used to connect the mounting components. Figure 1 and Figure 3The connecting assembly includes two connecting frames 4 and a movable guide. The two connecting frames 4 are rotatably mounted on one end of each of the two mounting assemblies and can slide relative to each other along the movable guide. By optimizing the structure of the connecting assembly, on the one hand, the two mounting frames 5 can rotate relative to the connecting frames 4, thus allowing the mounting frames to be folded for easy transport; on the other hand, since the two connecting frames 4 can slide relative to each other along the movable guide, when the two mounting frames 5 are unfolded, the connecting frames 4 can drive the two mounting frames 5 closer together and fix them to the columns, thereby preventing the two mounting frames 5 from rotating relative to each other again and improving the stability of the curtain wall installation. In this embodiment of the invention, the connecting frame 4 is a transverse U-shaped frame structure, which is rotatably fitted onto one end of the mounting frame.

[0052] As a further preferred embodiment of the present invention, such as Figure 4 As shown, the movable guide frame includes hollow tubes 14 and sleeves 13. There are two hollow tubes 14, arranged parallel to each other vertically and passing through two connecting frames 4. Both ends of each hollow tube 14 are slidably disposed within a sleeve 13, and each sleeve 13 is slidably mounted on a corresponding connecting frame 4. Furthermore, each sleeve 13 has a limiting plate on its inner side to prevent the inner side of the sleeve 13 from passing through the connecting frame 4, and the outer sides of two sleeves 13 on the same connecting frame 4 are connected by a fixing plate 12. By moving the connecting frame 4 along the hollow tubes 14 via the sleeves 13, the two mounting frames can be brought closer together.

[0053] As a further preferred embodiment of the present invention, both ends of the hollow tube 14 are provided with sealing rings 17, and the hollow tube 14 is connected to the negative pressure device through a one-way sealing assembly. The one-way sealing assembly includes a connecting pipe 16 and a one-way valve 15, wherein both ends of the connecting pipe 16 are respectively connected to the two hollow tubes 14, and the one-way valve 15 is installed on the connecting pipe 16 and connected to the connecting pipe 16. When the one-way valve 15 is connected to the negative pressure device and the switch of the negative pressure device is turned on, the negative pressure device extracts the gas in the hollow tube 14 and the sleeve 13 through the connecting pipe 16 and the sealing rings 17, so that the two connecting frames can move closer to each other. The above structure facilitates the movement of the mounting frames closer to each other and is simple to operate. On the other hand, it can also effectively prevent the two mounting frames from moving in opposite directions after installation, thus avoiding relative rotation and further improving the structural stability of the entire system.

[0054] As a further preferred embodiment of the present invention, the curtain wall system further includes two support components, respectively connected between the two mounting components and the two columns 1, for supporting and initially positioning the mounting components. Figure 2 , Figure 5 As shown, the above-mentioned support components include:

[0055] The annular plate 8 is rotatably mounted on the column 1; specifically, in this embodiment, the column 1 is provided with a connecting seat 7, and the annular plate 8 is rotatably connected to the outside of the connecting seat 7.

[0056] The first bracket 2 has one end fixedly installed on the annular plate 8, and the other end is detachably and rotatably connected to the connecting frame 4.

[0057] The second bracket 3 has one end fixedly mounted on the annular plate 8, and the other end detachably and rotatably connected to the mounting assembly on the side away from the connecting frame 4.

[0058] The rotation of the annular plate 8 drives the first bracket 2 and the second bracket 3 to rotate as well. This facilitates the pre-positioning and installation of the mounting frame. Furthermore, by pushing the first bracket 2 and the second bracket 3, once both are rotatably connected to the mounting frame 5, the two mounting frames 5 can be fully extended to 180 degrees, making operation relatively simple. At this point, sliding the two connecting brackets along the movable guide towards each other will bring the two mounting frames closer together, thus preventing further rotation of the mounting frames.

[0059] As a further preferred embodiment of the present invention, the annular plate 8 is provided with two parts, upper and lower. The first bracket 2 and the second bracket 3 are rotatably connected to the upper and lower ends of the mounting assembly. That is, the first bracket 2, the second bracket 3 and the mounting assembly surround to form a triangular prism structure, which is conducive to further improving the stability and installation strength of the overall structure.

[0060] As a further preferred embodiment of the present invention, combined with Figure 5 , Figure 6 The connecting frame 4 is equipped with a connecting column, and the free end of the first bracket 2 is correspondingly machined with a notch 19 that engages and rotates with the connecting column. The end of the mounting frame 5 away from the connecting frame 4 is machined with a connecting hole, and the free end of the second bracket 3 is correspondingly machined with a round hole 20. The second bracket 3 is rotatably connected to the mounting assembly via a connecting shaft 21. During installation, the curtain wall unit is first fixed to the mounting frame 5 via the mounting column 6. Then, one end of the mounting frame 5 is connected to the second bracket 3: the connecting shaft 21 is inserted into the connecting hole 20 on the mounting frame 5, thus achieving a rotatable connection between the mounting frame 5 and the second bracket 3. At this time, the first bracket 2 is rotated so that the connecting column on the connecting frame 4 engages with the notch 19, thereby achieving the connection between the first bracket 2 and the second bracket 3 and the mounting frame 5.

[0061] In an embodiment of the present invention, the mounting frame 5 is further provided with a support plate 11, and a connecting rod 9 is installed through the support plate 11. The outer side of the connecting rod 9 is threaded, and a threaded hole 18 matching the aforementioned thread is opened on the side wall of the column 1. The mounting frame and the column are initially connected and positioned by the support assembly, and then the mounting frame and the column are fixedly connected by the connecting rod 9, which helps to further improve the structural and connection stability of the entire system.

[0062] In an embodiment of this invention, the installation process of the large-span double-column unitized curtain wall system is as follows: Two installation components are connected using a connecting assembly, causing the installation components to rotate relative to the connecting frame 4, thereby folding the two installation components for easy transport to the construction site; the curtain wall units are then fixed onto the installation components, and finally, the installation components are installed onto the corresponding columns using a support assembly. During installation, the installation components rotate relative to the connecting frame, allowing the installation components to unfold to 180°. The specific operation process is as follows:

[0063] During use, the two mounting brackets 5 can be folded under the action of the connecting bracket 4, so that the large-span curtain wall unit can be folded for easy transportation. During installation, the curtain wall unit is first fixed to the mounting bracket 5 by the mounting column 6. Then, the end of the mounting bracket 5 is connected to the second bracket 3. The connecting shaft 21 is inserted into the connecting hole on the mounting bracket 5 through the round hole 20 to realize the rotational connection between the mounting bracket 5 and the second bracket 3. Then, the first bracket 2 is rotated. During the rotation of the first bracket 2, the connecting column on the mounting bracket 5 enters the notch 19. The first bracket 2 and the second bracket 3 are rotated again, so that the two mounting brackets 5 can be unfolded and the included angle between the two mounting brackets 5 is 180 degrees.

[0064] Connect the one-way valve 15 to the negative pressure device and turn on the switch of the negative pressure device. When the negative pressure device is working, it extracts the gas from the hollow tube 14 and sleeve 13 through the connecting pipe 16 and the sealing ring 17, so that the two sleeves 13 at both ends of the hollow tube 14 move closer to each other, and then the two connecting frames 4 move closer to each other, initially preventing the two mounting frames 5 from rotating again. Finally, push the connecting rod 9 so that the connecting rod 9 enters the threaded hole 18. The connecting rod 9 is driven to rotate through the transmission block 10. Through the action of the connecting rod 9 and the threaded hole 18, the mounting frame 5 and the column 1 are fixed to complete all the installation work. This allows the curtain wall system to be installed simultaneously on each floor without the need for lifting equipment to lift the curtain wall units one by one, which greatly improves the installation efficiency of the curtain wall units.
