Description

Technical Field

[0001] This invention belongs to the field of curtain wall construction technology, and particularly relates to a method for connecting curtain wall nodes. Background Technology

[0002] Curtain wall engineering is mainly applicable to large public buildings such as exhibition halls, libraries, and high-speed railway stations. A curtain wall typically consists of a main structure and a connecting structure, where the connecting structure can be made of steel or connecting devices.

[0003] However, for node connections requiring high tensile strength, existing plate cables are mainly composed of multiple curved panel components connected by fasteners. They rely on the friction between the curved panel components and / or the shear strength of the fasteners to withstand the tensile force. However, the above structure has weak points at the connection between the fasteners and the curved panel components, resulting in poor connection stability. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a connection method for curtain wall nodes to solve the problem of poor connection stability caused by weak points at the connection between the fasteners used for node connection and the curved panel components in the prior art.

[0005] The objective of this invention is mainly achieved through the following technical solutions.

[0019] Furthermore, the carbon fiber cable includes a top end, a composite plate, and a bottom end that are stacked in sequence;

[0020] The composite board consists of a carbon fiber body and structural layers. The carbon fiber body includes a central reinforcement and multiple layers of carbon fiber.

[0021] The central reinforcement is in the shape of an upright trapezoid. The multi-layer carbon fiber is divided into two groups. One group is located on one side of the central reinforcement and is fixedly connected to the side of the central reinforcement. The other group is located on the other side of the central reinforcement and is fixedly connected to the side of the central reinforcement.

[0022] In each group of carbon fiber layers, adjacent carbon fiber layers are arranged in parallel with gaps, and the structural layer is located in the gaps and is fixedly connected to the carbon fiber layers.

[0023] Furthermore, in step 1, the method for connecting the carbon fiber cables includes the following steps:

[0024] Step 11: Provide a top end, a bottom end, a carbon fiber body, and multiple structural layers;

[0025] Step 12: Adhere the multi-layer structural layers to the adjacent carbon fiber layers respectively, so that the carbon fiber layers and structural layers are stacked alternately to obtain the board to be cured;

[0026] Step 13: Attach the top and bottom ends to the board to be cured to obtain the cable body to be cured;

[0027] Step 14: Cure the cable body to be cured to obtain a cured cable body;

[0028] Step 15: Grind the top end, bottom end, and part of the structural layer on the cured cable to form an articulated ball, thus obtaining the carbon fiber cable.

[0029] Furthermore, the carbon fiber cable includes a top end, a carbon fiber frame, a bottom end, and a structural layer, with the top end, carbon fiber frame, and bottom end stacked sequentially.

[0030] Along the length of the carbon fiber frame, multiple parallel structural cavities are opened inside the carbon fiber frame. The lower surface of the structural cavity is convex arc-shaped, and the structural layer is located in the structural cavity and fixedly connected to the carbon fiber frame.

[0031] Furthermore, in step 1, the method for connecting the carbon fiber cables includes the following steps:

[0032] Step 11: Provide a top end, a bottom end, a carbon fiber frame, and a multi-layer structural layer;

[0033] Step 12: Adhere the multi-layer structural layers to the structural cavity of the carbon fiber frame to obtain the board to be cured;

[0034] Step 13: Attach the top and bottom ends to the board to be cured to obtain the cable body to be cured;

[0035] Step 14: Cure the cable body to be cured to obtain a cured cable body;

[0036] Step 15: Grind the top end, bottom end, and part of the structural layer on the cured cable to form an articulated ball, thus obtaining the carbon fiber cable.

[0037] Furthermore, step 2 includes the following steps:

[0038] Step 21: Place the first arc-shaped plate and the second arc-shaped plate on both sides of the hinge ball, with the first arc-shaped plate and the second arc-shaped plate in contact, and the threads on the first arc-shaped plate and the threads on the second arc-shaped plate aligning to form a threaded hole;

[0039] Step 22: Pass the through-hole connector through the through-hole on the first arc-shaped plate and the through-hole on the second arc-shaped plate to pre-connect and pre-position the first arc-shaped plate and the second arc-shaped plate;

[0040] Step 23: Insert the screw into the threaded hole and fix it in place to complete the fixed connection between the first arc-shaped plate and the second arc-shaped plate.

[0041] Step 24: Remove the through-connector.

[0042] Furthermore, step 3 includes the following steps:

[0043] Step 31: Insert part of the anchor head into the connecting sleeve and screw it until the through hole at the front end of the connecting sleeve is aligned with the anchor head connection hole of the anchor head;

[0044] Step 32: Insert one of the anchor connectors into the through hole at the front end of the connecting sleeve and the anchor head connection hole on the anchor head, and adjust the installation direction of the connecting sleeve and the anchor head so that the axis of the connecting sleeve coincides with the axis of the anchor head.

[0045] Step 33: Remove the anchor connector from the connecting sleeve and continue inserting the anchor head into the connecting sleeve until the through hole at the rear end of the connecting sleeve and the anchor head connection hole are aligned.

[0046] Step 34: Insert the anchor connector into the through hole and anchor head connection hole at the rear end of the connecting sleeve until the anchor connector extends to at least 1 / 2 of the thickness of the connecting sleeve, so that the connecting sleeve and the anchor head are fixedly connected.

[0047] Furthermore, step 3 is followed by the following steps:

[0048] Step 4: Screw the sealing sleeve into the connecting sleeve until the sealing sleeve abuts against the hinge ball on the carbon fiber cable.

[0049] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects.

[0050] The connection method for curtain wall nodes provided by this invention adopts a pressure-bearing end-loaded approach. A ball-and-socket structure is formed by the interaction between the hinge ball on the carbon fiber cable and the annular protrusion on the connecting sleeve. The side of the annular protrusion facing the hinge ball is the pressure-bearing surface. The annular protrusion constrains the displacement of the hinge ball along the length of the carbon fiber cable. The ball-and-socket structure bears the tensile force generated by the carbon fiber cable during later use. The structure is simple, reliable, and easy to assemble. It can not only effectively reduce the size of the connection device, but also reduce the shear force caused by human factors during installation and temperature loads during use of the carbon fiber cable, while taking into account the aesthetic requirements of building curtain walls and light steel engineering.

[0051] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention.

Detailed Implementation

[0064] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0065] Example 1

[0066] This embodiment provides a method for connecting curtain wall nodes. See [link to relevant documentation]. Figure 1 It includes the following steps:

[0067] Step 1: Provide two node plates, fix one node plate to the upper curtain wall node position, and fix the other node plate to the lower curtain wall node position.

[0068] A carbon fiber cable 1 is provided, with hinged balls at both ends near the ends;

[0069] Step 2: The connecting sleeve 2 is fitted onto the outer wall of the end of the carbon fiber cable 1. The inner wall of the connecting sleeve is provided with an annular protrusion 25. The hinge ball is located on the side of the annular protrusion 25 away from the center of the carbon fiber cable 1. The hinge ball and the annular protrusion 25 form a ball-joint structure.

[0070] Step 3: Insert the connecting sleeve 2 into the anchor head 3, and fix the anchor head 3 and the connecting sleeve 2 in place;

[0071] Step 4: Pivot the end of the anchor head 3 away from the carbon fiber cable 1 to the node plate to complete the connection of the curtain wall node.

[0072] Compared with the prior art, the connection method of the curtain wall node provided in this embodiment adopts a pressure-bearing end force-bearing method. The ball joint structure is formed by the interaction between the hinge ball on the carbon fiber cable 1 and the annular protrusion 25 on the connecting sleeve 2. The side of the annular protrusion 25 facing the hinge ball is the pressure-bearing surface. The annular protrusion 25 constrains the displacement of the hinge ball along the length direction of the carbon fiber cable 1. The ball joint structure bears the tensile force generated by the carbon fiber cable 1 in the later use. The structure is simple, the force is reliable, and the assembly is convenient. It can not only effectively reduce the size of the connection device, but also reduce the shear force caused by human factors during installation and temperature load during use of the carbon fiber cable 1, while taking into account the aesthetic requirements of building curtain walls and light steel engineering.

[0073] Specifically, in step 1 above, the carbon fiber cable 1 can adopt the following three structures, and correspondingly, there are also three ways to connect the carbon fiber cable 1.

[0074] The first structure, while ensuring the structural strength of the carbon fiber cable 1, aims to effectively save on the amount of carbon fiber used and reduce costs. For the structure of the carbon fiber cable 1, please refer to [reference needed]. Figure 5Specifically, it includes a top end 11, a composite plate, and a bottom end 12 stacked sequentially. The composite plate includes alternatingly stacked and fixedly connected (e.g., bonded) carbon fiber layers 13 and a structural layer 14. The structural layer 14 can be a metal plate or a composite material plate. The sides of both ends of the structural layer 14 have arc-shaped enlargements. The top end 11, the enlargements of the structural layer 14, and the bottom end 12 form a hinged ball. In this way, since the enlargements are integrally formed with the structural layer 14, the quality of the carbon fiber cable 1 can be ensured, and weak points on the carbon fiber cable 1 can be reduced.

[0075] In order to reduce the creep of the carbon fiber cable 1 during use, the thickness of the carbon fiber layer 13 gradually increases from top to bottom. This is because the creep of carbon fiber material is relatively small, while the creep of the carbon fiber cable 1 is mainly concentrated on the lower surface. By increasing the thickness of the carbon fiber layer 13, the creep of the carbon fiber cable 1 during use can be effectively reduced.

[0076] To facilitate the manufacture and installation of the carbon fiber cable 1, for example, the distance between the side of the hinge ball facing the end of the carbon fiber cable 1 and the end of the carbon fiber cable 1 is 100 to 300 mm, that is, the length of the end of the carbon fiber cable 1 beyond the hinge ball is 100 to 300 mm.

[0077] In order to improve the mechanical strength of the carbon fiber cable 1 along its length, the fiber direction in the carbon fiber layer 13 is the same as the length direction of the carbon fiber cable 1.

[0078] To ensure the connection stability between the multi-layer carbon fiber layer 13 and the multi-layer structural layer 14 in the composite board, the carbon fiber cable 1 also includes a cable connector 15. A structural layer connection hole is formed on the enlarged portion of the structural layer 14, a top connection hole is formed on the top end 11, and a bottom connection hole is formed on the bottom end 12. The cable connector 15 passes through the top connection hole, the structural layer connection hole, and the bottom connection hole, and is fixedly connected to the top end 11, the enlarged portion, and the bottom end 12 respectively, so that the top end 11, the bottom end 12, and the multi-layer structural layer 14 form an integral structure, thereby ensuring the overall stability of the carbon fiber cable 1. Furthermore, during the manufacturing process of the carbon fiber cable 1, the aforementioned cooperating cable connector 15, the structural layer connection hole, the top connection hole, and the bottom connection hole can also position the top end 11, the structural layer 14, and the bottom end 12, ensuring the processing quality of the carbon fiber cable 1.

[0079] For the carbon fiber cable 1 of the first structure, the connection method of the carbon fiber cable 1 in step 1 above includes the following steps:

[0080] Step 11: Provide a top end 11, a bottom end 12, a multi-layer carbon fiber layer 13, and a multi-layer structural layer 14;

[0081] Step 12: Alternately stack and bond the multi-layer carbon fiber layer 13 and multi-layer structural layer 14 to the designed thickness to obtain the board to be cured;

[0082] Step 13: Bond the top end 11 and the bottom end 12 to the board to be cured, respectively, to obtain the cable body to be cured;

[0083] Step 14: Cure the cable body to be cured to obtain a cured cable body;

[0084] Step 15: Grind the top end 11, bottom end 12 and enlarged portion on the cured cable to form an articulated ball, thus obtaining the carbon fiber cable 1.

[0085] For the second structure, regarding the structure of carbon fiber cable 1, see [link / reference]. Figure 8 Specifically, it includes a top end 11, a composite plate, and a bottom end 12 stacked sequentially. The composite plate includes a carbon fiber body and a structural layer 14 (e.g., a metal layer). The carbon fiber body includes a central reinforcement 16 and multiple carbon fiber layers 13. The central reinforcement 16 and the carbon fiber layers 13 are both made of carbon fiber and are integrally formed. The central reinforcement 16 is in the shape of an upright trapezoid. The multiple carbon fiber layers 13 are divided into two groups. One group is located on one side of the central reinforcement 16 and is fixedly connected to the side of the central reinforcement 16. The other group is located on the other side of the central reinforcement 16 and is fixedly connected to the side of the central reinforcement 16. In each group of carbon fiber layers 13, two adjacent carbon fiber layers 13 are arranged in parallel and have a gap. The structural layer 14 is located in the gap and is fixedly connected to the carbon fiber layer 13 (e.g., by bonding). Thus, a central reinforcement 16 is positioned at the center of the carbon fiber cable 1, and the central reinforcement 16 is an upright trapezoid. This means that the cross-section of the central reinforcement 16 gradually increases from top to bottom, resulting in gradually increasing strength, which effectively reduces creep of the connecting device during use. Furthermore, since the central reinforcement 16 is integrally formed with the carbon fiber layer 13, adjacent carbon fiber layers 13 are connected by the central reinforcement 16, and the structural layer 14 is sandwiched between adjacent carbon fiber layers 13. In practical applications, this effectively reduces the occurrence of delamination.

[0086] For the carbon fiber cable 1 of the second structure, the connection method of the carbon fiber cable 1 in step 1 above includes the following steps:

[0087] Step 11: Provide a top end 11, a bottom end 12, a carbon fiber body, and a multi-layer structural layer 14;

[0088] Step 12: Adhere the multi-layer structural layer 14 to the adjacent two carbon fiber layers respectively, so that the carbon fiber layer 13 and the structural layer 14 are stacked alternately to obtain the board to be cured;

[0089] Step 13: Bond the top end 11 and the bottom end 12 to the board to be cured, respectively, to obtain the cable body to be cured;

[0090] Step 14: Cure the cable body to be cured to obtain a cured cable body;

[0091] Step 15: Grind the top end 11, bottom end 12 and part of the structural layer 14 on the cured cable to form an articulated ball, thus obtaining the carbon fiber cable 1.

[0092] For the third structure, see the structure of carbon fiber cable 1. Figure 9 Specifically, it includes a top end 11, a carbon fiber frame 17, and a bottom end 12 stacked sequentially. Multiple parallel structural cavities are formed within the carbon fiber frame 17 along its length. The lower surface of each structural cavity is convexly curved, meaning the surface of the carbon fiber frame 17, which serves as the lower surface of the structural cavity, is also convexly curved. The structural layer 14 is located within the structural cavity and is fixedly connected to the carbon fiber frame 17 (e.g., bonded). By using the carbon fiber frame 17 as the main structure of the carbon fiber cable 1, and the convexly curved surface of the carbon fiber frame 17, which serves as the lower surface of the structural cavity, the thickness of the carbon fiber at the center of the carbon fiber cable 1 is effectively increased, thereby effectively reducing creep during use. Furthermore, since the carbon fiber frame 17 is a one-piece molded structure, delamination can be effectively reduced in practical applications.

[0093] For the carbon fiber cable 1 of the third structure, the connection method of the carbon fiber cable 1 in step 1 above includes the following steps:

[0094] Step 11: Provide a top end 11, a bottom end 12, a carbon fiber frame 17, and a multi-layer structural layer 14;

[0095] Step 12: Adhere the multi-layer structural layers 14 to the structural cavity of the carbon fiber frame 17 to obtain the board to be cured;

[0096] Step 13: Bond the top end 11 and the bottom end 12 to the board to be cured, respectively, to obtain the cable body to be cured;

[0097] Step 14: Cure the cable body to be cured to obtain a cured cable body;

[0098] Step 15: Grind the top end 11, bottom end 12 and part of the structural layer 14 on the cured cable to form an articulated ball, thus obtaining the carbon fiber cable 1.

[0099] To facilitate the connection between the hinged ball and the connecting sleeve 2, the connecting sleeve 2 is a split structure, including a first arc-shaped plate 21 and a second arc-shaped plate 22, see [link to details]. Figures 6-7The two can be detached and fixedly connected to form a connecting sleeve 2.

[0100] In order to position the connecting sleeve 2 of the split structure during the installation process, one end of the first arc-shaped plate 21 and one end of the second arc-shaped plate 22 are provided with threads. The threads on the first arc-shaped plate 21 and the threads on the second arc-shaped plate 22 are joined to form a threaded hole. The connecting sleeve 2 also includes a screw 23, which is threadedly connected to the threaded hole, thereby realizing the fixed connection between the first arc-shaped plate 21 and the second arc-shaped plate 22.

[0101] For example, through holes with corresponding positions are opened on the arc surface of the first arc plate 21 and the arc surface of the second arc plate 22. The connecting sleeve 2 also includes a through connector 24, which passes through the through holes to pre-connect and pre-position the first arc plate 21 and the second arc plate 22. It should be noted that in order to avoid the installation of the sealing sleeve 4 by setting the through connector 24 later, the through connector 24 needs to be removed after the first arc plate 21 and the second arc plate 22 are stably installed.

[0102] Based on the structure of the connecting sleeve 2, in order to accurately and stably fit the connecting sleeve 2 onto the outer wall of the carbon fiber cable 1, step 2 above includes the following steps:

[0103] Step 21: Place the first arc-shaped plate 21 and the second arc-shaped plate 22 on both sides of the hinge ball, with the first arc-shaped plate 21 and the second arc-shaped plate 22 in contact, and the threads on the first arc-shaped plate 21 and the threads on the second arc-shaped plate 22 merging to form a threaded hole.

[0104] Step 22: Pass the through-hole connector 24 through the through-hole on the first arc-shaped plate 21 and the second arc-shaped plate 22 to pre-connect and pre-position the first arc-shaped plate 21 and the second arc-shaped plate 22;

[0105] Step 23: Insert screw 23 into threaded hole and fix it to the threaded hole to complete the fixed connection of the first arc plate 21 and the second arc plate 22. The hinge ball is located on the side of the annular protrusion 25 away from the center of the carbon fiber cable 1. The hinge ball and the annular protrusion 25 form a ball hinge structure.

[0106] Step 24: Remove the through-connector 24.

[0107] In order to ensure that the connecting sleeve 2 is accurately and stably inserted into the anchor head 3, step 3 above includes the following steps:

[0108] Step 31: Insert part of the anchor head 3 into the connecting sleeve 2, and screw it until the through hole at the front end (i.e. the insertion end) of the connecting sleeve 2 is aligned with the anchor head connection hole of the anchor head 3;

[0109] Step 32: Insert one of the anchor connectors 33 into the through hole and anchor head connection hole at the front end of the connecting sleeve 2, and adjust the installation direction of the connecting sleeve 2 and the anchor head 3 so that the axis of the connecting sleeve 2 coincides with the axis of the anchor head 3;

[0110] Step 33: Remove the anchor connector 33 from the connecting sleeve 2, and continue to insert the anchor head 3 into the connecting sleeve 2 until the through hole at the rear end of the connecting sleeve 2 and the anchor head connection hole are aligned.

[0111] Step 34: Insert the anchor connector 33 into the through hole and anchor head connection hole at the rear end of the connecting sleeve 2 until the anchor connector 33 extends to at least 1 / 2 of the thickness of the connecting sleeve 2, so that the connecting sleeve 2 and the anchor head 3 are fixedly connected.

[0112] To reduce the reverse slippage of the articulated ball, the above-mentioned connecting device also includes a sealing sleeve 4. One end of the sealing sleeve 4 is inserted into the connecting sleeve 2 from the end away from the articulated ball and abuts against the articulated ball. In this way, the sealing sleeve 4, the connecting sleeve 2, and the annular protrusion 25 together form a hinge groove for accommodating the articulated ball on the side facing the articulated ball. The hinge groove and the articulated ball cooperate with each other, and the sealing sleeve 4 limits the articulated ball in the reverse direction.

[0113] It is understandable that, in order to achieve a fixed connection between the sealing sleeve 4 and the connecting sleeve 2, the above-mentioned connecting device also includes a sealing connector. The sealing sleeve 4 has a sealing connection hole, and the connecting sleeve 2 has a fixed connection hole. The sealing connector passes through the sealing connection hole and the fixed connection hole and is fixedly connected to the sealing sleeve 4 and the connecting sleeve 2 respectively, so that the sealing sleeve 4 and the connecting sleeve 2 form an integral structure.

[0114] In order to reduce the contamination of the ball joint structure by external pollution during the use of the connecting device, the other end of the sealing sleeve 4 is provided with a head plate 5. The outer diameter of the head plate 5 is larger than the inner diameter of the connecting sleeve 2. In this way, the head plate 5 plays a sealing role, thereby reducing the impact of external adverse factors such as rainwater and dust on the ball joint structure during later use.

[0115] It is understandable that when the connecting device includes the sealing sleeve 4, the following steps are included after step 3 above:

[0116] Step 4: Screw the sealing sleeve 4 into the connecting sleeve 2 until the sealing sleeve 4 abuts against the hinge ball on the carbon fiber cable 1.

[0117] For example, the above connection method employs a connection device with the following structure:

[0118] See Figures 2-4The connecting device includes a node plate, a carbon fiber cable 1, and an anchor. The carbon fiber cable 1 has a hinge ball near its end. The anchor includes a connecting sleeve 2 and an anchor head 3. The anchor head 3 is fitted onto the outer wall of the connecting sleeve 2 and is fixedly connected to the connecting sleeve 2. The inner wall of the connecting sleeve is provided with an annular protrusion 25. The connecting sleeve is fitted onto the outer wall of the end of the carbon fiber cable 1. The hinge ball is located in the connecting sleeve 2, and the annular protrusion 25 is located on the side of the hinge ball away from the end of the carbon fiber cable 1. The diameter of the hinge ball is larger than the inner diameter of the annular protrusion 25, so that the connecting sleeve 2 and the hinge ball form a ball-joint structure. The end of the anchor head 3 away from the carbon fiber cable 1 is pivotally connected to the node plate.

[0119] Specifically, the structure of the anchor head 3 includes an anchor sleeve 31 and an ear plate 32 connected to the anchor sleeve 31. The anchor sleeve 31 is fitted onto the outer wall of the connecting sleeve 2, and the ear plate 32 is connected to the main building structure.

[0120] In order to achieve a fixed connection between the anchor head 3 and the connecting sleeve 2, for example, the anchor head 3 is provided with an anchor head connection hole, the connecting sleeve 2 is provided with a sleeve connection hole, and the anchor also includes an anchor connector 33.
