Description

Technical Field

[0001] This invention belongs to the field of carbon fiber plate and cable structure technology, and particularly relates to a carbon fiber plate and cable and its production method. Background Technology

[0002] In recent years, with the development of the industry, cable structures have been widely used in curtain wall projects of large public buildings such as exhibition halls, libraries, and high-speed railway stations. Compared with the main structure, curtain wall steel structures mostly adopt light steel structure systems, with smaller steel specifications and high decorative requirements, which significantly affects the overall aesthetics of the building. Due to its material properties, carbon fiber materials have superior mechanical properties along their fiber direction. Compared with ordinary cables, it can achieve a smaller design cross-section under the same tensile force requirements, thus meeting the aesthetic needs of buildings. Therefore, it has been introduced into the field of curtain wall and light steel engineering.

[0003] However, high-tensile carbon fiber plate cables place high demands on anchorages. Existing carbon fiber plate cable anchorages generally rely on the friction of the connecting plates or the shear strength of the fasteners to achieve anchor heads. In order to meet the tensile requirements of the design, the anchor heads are usually relatively large and the manufacturing process is complex. When used in curtain walls and light steel engineering, this greatly affects the appearance of certain parts of the building. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a carbon fiber plate cable and its production method to solve the problems of large anchor heads, complex manufacturing process, and negative impact on the appearance of buildings in the prior art.

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

[0006] The present invention provides a carbon fiber cable, including a carbon fiber cable body and an anchor. The carbon fiber cable body has a hinged ball near the end. The anchor includes a connecting sleeve and an anchor head. The anchor head is sleeved on the outer wall of the connecting sleeve and fixedly connected to the connecting sleeve. The hinged ball is hinged to the connecting sleeve.

[0007] Furthermore, the inner wall of the connecting sleeve is provided with an annular protrusion, the connecting sleeve is fitted onto the outer wall of the end of the carbon fiber cable, the hinge ball is located in the connecting sleeve and the annular protrusion is located on the side of the hinge ball away from the end of the carbon fiber cable, the diameter of the hinge ball is larger than the inner diameter of the annular protrusion, and the connecting sleeve and the hinge ball form a ball-joint structure.

[0008] Furthermore, the anchor head includes an anchor body sleeve and a lug connected to the anchor body sleeve, wherein the anchor body sleeve is fitted onto the outer wall of the connecting sleeve.

[0009] Furthermore, an anchor head connection hole is opened on the anchor head, and a sleeve connection hole is opened on the connecting sleeve. The anchor also includes an anchor connector, which passes through the anchor head connection hole and the sleeve connection hole in sequence and is fixedly connected to the anchor head and the connecting sleeve.

[0010] Furthermore, the carbon fiber cable includes a top end, a composite plate, and a bottom end that are stacked sequentially, and the composite plate includes alternating and fixedly connected carbon fiber layers and structural layers.

[0011] Furthermore, the sides at both ends of the structural layer have arc-shaped enlargements, and the top end, the enlargements of the structural layer, and the bottom end constitute a hinged ball.

[0012] Furthermore, the thickness of the carbon fiber layers gradually increases from top to bottom.

[0013] Furthermore, the fiber orientation in the carbon fiber layer is the same as the length orientation of the carbon fiber strand.

[0014] Furthermore, the distance between the side of the articulated ball facing the end of the carbon fiber cable and the end of the carbon fiber cable is 100–300 mm.

[0015] Furthermore, it also includes a sealing sleeve that abuts against the hinged ball; the other end of the sealing sleeve is provided with a head plate, the outer diameter of which is larger than the inner diameter of the connecting sleeve.

[0016] The present invention also provides a method for producing carbon fiber plates and cables, for producing the aforementioned carbon fiber plates and cables, the method comprising the following steps:

[0017] The carbon fiber cable body, connecting sleeve, and anchor head are sequentially fitted together to obtain the carbon fiber plate cable.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects.

[0019] The carbon fiber plate cable provided by this invention improves the end of the carbon fiber cable by adopting a pressure-bearing end force-bearing method. The hinge ball on the carbon fiber cable interacts with the annular protrusion on the connecting sleeve to form a ball-joint structure. 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-joint structure bears the tensile force generated by the carbon fiber cable during later use. The structure is simple, reliable in force bearing, and easy to assemble. It can not only effectively reduce the size of the carbon fiber plate cable, but also reduce the shear force caused by human factors during installation and temperature loads during use, while taking into account the aesthetic requirements of building curtain walls and light steel engineering.

Detailed Implementation

[0032] 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.

[0033] Example 1

[0034] This embodiment provides a carbon fiber plate cable, see [link / reference] Figures 1 to 3 The system includes 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.

[0035] Compared with the prior art, the carbon fiber plate cable provided in this embodiment improves the end of the carbon fiber cable body 1 by adopting a pressure-bearing end force-bearing method. The hinge ball on the carbon fiber cable body 1 interacts with the annular protrusion 25 on the connecting sleeve 2 to form a ball-joint structure. 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 body 1. The ball-joint structure bears the tensile force generated by the carbon fiber cable body 1 during 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 carbon fiber plate cable, but also reduce the shear force caused by human factors during installation and temperature loads during use, while taking into account the aesthetic requirements of building curtain walls and light steel engineering.

[0036] 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.

[0037] 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. The anchor connector 33 passes through the anchor head connection hole and the sleeve connection hole in sequence and is fixedly connected to the anchor head 3 and the connecting sleeve 2, so that the anchor connector 33, the anchor head 3 and the connecting sleeve 2 constitute a structural whole.

[0038] 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 5 to 6 The two can be detached and fixedly connected to form a connecting sleeve 2.

[0039] 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.

[0040] 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.

[0041] To ensure the structural strength of the carbon fiber cable 1, and in order to effectively save on the amount of carbon fiber used and reduce costs, the structure of the carbon fiber cable 1 is described in detail below. Figure 4 Specifically, 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] To reduce the reverse slippage of the articulated ball, the aforementioned carbon fiber plate cable 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.

[0047] It is understandable that, in order to achieve a fixed connection between the sealing sleeve 4 and the connecting sleeve 2, the carbon fiber plate cable 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.

[0048] In order to reduce the contamination of the ball joint structure by external pollution during the use of carbon fiber plates and cables, a head plate 5 is provided at the other end of the sealing sleeve 4. 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.

[0049] For example, the anchor connector 33, cable connector 15 and sealing connector are made of metal or composite materials, and these components are bolts or rivets, etc.

[0050] Example 2

[0051] This embodiment provides a carbon fiber plate, the structure of which is basically the same as the carbon fiber cable provided in Embodiment 1, the difference being:

[0052] For the structure of carbon fiber cable 1, see Figure 7 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).

[0053] Compared with the prior art, the carbon fiber plate and cable provided in this embodiment has a central reinforcement 16 at the center of the carbon fiber cable body 1. The central reinforcement 16 is an upright trapezoid, meaning that the cross-section of the central reinforcement 16 gradually increases from top to bottom, and the strength gradually increases, thereby effectively reducing the creep of the carbon fiber plate and cable during use. In addition, 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 can effectively reduce the occurrence of delamination.

[0054] Example 3

[0055] This embodiment provides a carbon fiber plate cable, whose structure is basically the same as that of the carbon fiber plate cable provided in Embodiment 1, the difference being:

[0056] For the structure of carbon fiber cable 1, see Figure 8 Specifically, it includes a carbon fiber frame 17, with multiple parallel structural cavities formed within the carbon fiber frame 17 along its length. The lower surface of each structural cavity is convex arc-shaped, meaning that the surface of the carbon fiber frame 17, which serves as the lower surface of the structural cavity, is convex arc-shaped. The structural layer 14 is located within the structural cavity and is fixedly connected to the carbon fiber frame 17 (e.g., bonded).

[0057] Compared with the prior art, the carbon fiber plate and cable provided in this embodiment uses the carbon fiber frame 17 as the main structure of the carbon fiber cable body 1. The surface of the carbon fiber frame 17, which serves as the lower surface of the structural cavity, is convex and arc-shaped. This effectively increases the thickness of the carbon fiber at the center of the carbon fiber cable body 1, thereby effectively reducing creep during use. Furthermore, since the carbon fiber frame 17 is a one-piece molded structure, it effectively reduces the occurrence of delamination in practical applications.

[0058] Example 4

[0059] This embodiment provides a method for producing carbon fiber plates and cables, used in the production of the carbon fiber plates and cables provided in Embodiment 1, Embodiment 2, or Embodiment 3. The production method includes the following steps:

[0060] Step 1: Provide a carbon fiber cable;

[0061] Step 2: Place the connecting sleeve on the outer wall of the carbon fiber cable, with the hinge ball located on the side of the annular protrusion away from the center of the carbon fiber cable. The hinge ball and the annular protrusion form a ball-joint structure.

[0062] Step 3: Insert the connecting sleeve into the anchor head, and fix the anchor head and the connecting sleeve in place.

[0063] Specifically, in step 1 above, the carbon fiber cable of Example 1 includes a top end, a composite plate, and a bottom end stacked sequentially. Accordingly, the production method of the carbon fiber cable includes the following steps:

[0064] Step 11: Provide a top end, a bottom end, and multiple carbon fiber layers and multiple structural layers;

[0065] Step 12: Alternately stack and bond multiple layers of carbon fiber and multiple layers of structural material to the designed thickness to obtain the board to be cured;

[0066] Step 13: Attach the top and bottom ends to the board to be cured to obtain the cable body to be cured;

[0067] Step 14: Cure the cable body to be cured to obtain a cured cable body;

[0068] Step 15: Grind the top end, bottom end, and enlarged portion of the cured cable to form an articulated ball, thus obtaining the carbon fiber cable.

[0069] In order to accurately and stably fit the connecting sleeve onto the outer wall of the carbon fiber cable, step 2 above includes the following steps:

[0070] 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;

[0071] 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;

[0072] Step 23: Insert the screw into the threaded hole and fix it to the threaded hole to complete the fixed connection between the first arc-shaped plate and the second arc-shaped plate. The hinge ball is located on the side of the annular protrusion away from the center of the carbon fiber cable. The hinge ball and the annular protrusion form a ball-hinge structure.

[0073] Step 24: Remove the through-connector.

[0074] To ensure that the connecting sleeve is accurately and stably inserted into the anchor head, step 3 above includes the following steps:

[0075] Step 31: Insert part of the anchor head into the connecting sleeve and screw it on until the through hole at the front end (i.e. the insertion end) of the connecting sleeve is aligned with the anchor head connection hole of the anchor head;

[0076] Step 32: Insert one of the anchor connectors into the through hole at the front end of the connecting sleeve and the anchor head connecting hole, 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.

[0077] 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.

[0078] 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.

[0079] It is understandable that when carbon fiber sheets and cables include sealing sleeves, the following steps are included after step 3 above:

[0080] Step 4: Screw the sealing sleeve into the connecting sleeve until the sealing sleeve abuts against the hinge ball on the carbon fiber cable.

[0081] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
