Description

Technical Field

[0001] The present invention relates to the field of composite material processing for structural engineering, and in particular to a device for circumferentially cross-wrapping a rib tube with a cloth strip and a method for using the device. Background Art

[0002] In the field of structural engineering, seawater-sand concrete has become an emerging building material due to the shortage of freshwater and river sand resources and their impact on the ecological environment. However, the corrosive effects of this concrete on traditional steel can lead to structural safety issues. Consequently, the search for new building materials compatible with seawater-sand concrete has begun. Fiber-reinforced polymer (FRP) composites, with their advantages such as light weight, high strength, good corrosion resistance, and designability, are considered an ideal alternative, particularly for marine engineering structures.

[0003] FRP pipes reinforced with circumferential fibers can significantly improve the bearing capacity and ductility of structures. They can also serve as permanent formwork, simplifying the construction process and improving the durability of structures. However, circumferential fiber FRP pipes are insufficient in resisting lateral forces and typically require use with longitudinal reinforcement to resist eccentric pressure or horizontal loads. Currently, circumferential fiber FRP pipes and longitudinal reinforcement are typically separated, making them difficult to form into an integrated structure. Even when bonded together, the reinforcement is often exposed, affecting the overall quality of the pipe.

[0004] To solve this problem, a new type of FRP cloth circumferential cross-woven reinforcement tube has been developed. This tube is formed into a cylindrical shape by equally spaced reinforcements, which are then cross-woven with FRP cloth strips. It not only inherits the advantages of circumferential fiber FRP tubes, but also enhances the ability to resist lateral and circumferential forces. The reinforcement can be FRP bars or steel bars to improve the ductility of the structure. The woven texture also helps to enhance the bonding between the FRP reinforcement tube and the concrete, thereby improving the performance of the overall component. However, the construction of this type of FRP cloth circumferential cross-woven reinforcement tube currently relies mainly on manual labor, and there are challenges in precision control.

[0005] In order to improve construction accuracy and efficiency, it is necessary to develop a circumferential cross-wrapped rib tube device and a method for using the same to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figures 1 to 9As shown, the present invention provides a device for circumferentially cross-wrapping a cloth strip around a rib tube, comprising a rib tube base 1, a placement base 2, and a control base 3. The three bases are of the same height, that is, they have the same upper bearing surface; wherein the rib tube base 1 is located between the placement base 2 and the control base 3; specifically, a driving gear 7 is rotatably connected to the top of the control base 3, and the driving gear 7 is supported at the center of the top of the control base 3 via a driving gear connecting shaft 12, and the driving gear 7 is rotatably connected to the upper end of the driving gear connecting shaft 12. A first rod 5 is fixedly attached to the center of the upper portion of the ribbed tube base 1. A rotating platform 4 is rotatably connected to the telescopic end of the first rod 5 (the end away from the ribbed tube base 1). The rotating platform 4 is cylindrical, and its outer circumference is used to attach and fix a cloth roll 10. A plurality of even-numbered ribbed tube fixing gears 8 are evenly distributed around the ribbed tube base 1 around the first rod 5. Each ribbed tube fixing gear 8 meshes with each other, and one of the ribbed tube fixing gears 8 meshes with the driving gear 7. Each of the ribbed tube fixing gears 8 rotates on the ribbed tube base 1 via a ribbed tube fixing gear connecting shaft 11. Driven by the driving gear 7, each of the ribbed tube fixing gears 8 rotates synchronously and alternately. Each of the ribbed tube fixing gears 8 is provided with a clamping unit for securing the ribbed tube 9. A second rod 6 is fixedly attached to the center of the upper portion of the placement base 2. The height of the second rod 6 is adjustable, and its top end (the end away from the placement base 2) is used to place the cloth roll 10. Specifically, a second rod placement platform 65 is fixed near the top of the rod to support the cloth roll 10 from the bottom.

[0044] Before use, the aforementioned device for circumferentially cross-wrapping fabric strips around rib tubes is preceded by placing a fabric roll 10 on the second rod mounting platform 65. The fabric roll 10 is coupled to the second rod 6 for free rotation, and one end of the fabric strip is affixed to the outer periphery of the rotating platform 4. Each rib tube 9 is affixed to each rib tube fixing gear 8. Rotating the driving gear 7 drives the rib tube fixing gear 8, causing the rib tubes 9 affixed to each rib tube fixing gear 8 to rotate as the gears rotate. When two adjacent rib tubes 9 intersect, the fabric strips, which have been straightened and affixed to the outside of the rotating platform 4, wind around the rib tubes 9 as the rotating platform rotates, falling into the gaps between the interlaced rib tubes 9. Reverse rotation of the driving gear 7 drives the rib tubes 9 against the fabric strips, causing them to interlace in the opposite direction, resulting in a cross-woven fabric strip. This process is repeated until the cross-woven fabric strips are formed.

[0045] According to a further optimization scheme, the diameter of the rib tube base 1 is the diameter of the cross-woven rib tube plus the radius of the rib tube fixing gear 8, the diameter of the control base 3 is consistent with the diameter of the driving gear 7, and the diameter of the mounting base 2 is slightly larger than the control base 3.

[0046] To further optimize the solution, the centers of the three bases can be on the same straight line, the three bases can be set to a cylindrical structure, and the ribbed tube base 1 is tangent to the placement base 2 and the control base 3 respectively; the ribbed tube base 1 is coaxial with the cross-woven ribbed tube of the cloth strip, and an axial hole for installing the first rod body 5 is reserved in the center of the ribbed tube base 1, and axial holes with the same number as the ribbed tube 9 are reserved on the outer side of the axial hole. These outer axial holes are used to install the ribbed tube fixing gear connecting shaft 11; an axial hole for installing the second rod body 6 is reserved in the center of the placement base 2; and an axial hole for installing the driving gear connecting shaft 12 is reserved in the center of the control base 3.

[0047] Further optimization scheme, such as Figure 5 As shown, the rib-tube fixed gear connecting shaft 11 is a T-shaped cylindrical rod structure with a thin upper end and a thick lower end; wherein, the upper end of the rib-tube fixed gear connecting shaft 11 is a rib-tube fixed gear fixing rod 111, which is used to rotate with the rib-tube fixed gear 8, and its diameter is slightly smaller than the center hole of the rib-tube fixed gear 8 to ensure that the rib-tube fixed gear 8 can rotate freely, and the lower end is used to be fixedly connected to the rib-tube base 1, and the diameter of the lower end is adapted to the diameter of the shaft hole reserved on the rib-tube base 1 to ensure that the two are firmly and tightly connected.

[0048] Further optimization scheme, such as Figure 5 As shown, the driving gear connecting shaft 12 is also a T-shaped cylindrical rod structure with a thin upper end and a thick lower end; wherein, the upper end of the driving gear connecting shaft 12 is a driving gear fixing rod 121, which is used to rotate with the driving gear 7, and its diameter is slightly smaller than the center hole of the driving gear 7 to ensure that the driving gear 7 can rotate freely, and the lower end is used to be fixedly connected to the control base 3, and the diameter of the lower end is adapted to the aperture of the shaft hole reserved on the control base 3 to ensure that the two are firmly and tightly connected.

[0049] Further optimization scheme, such as Figure 7 As shown, the first rod body 5 includes a first rod outer rod 51, a first rod inner rod 52 and a first rod body pin 53. The first rod outer rod 51 is a hollow tube, and a through hole is opened on the rod body near the top, which runs through the front and back of the rod body. The first rod inner rod 52 is axially inserted into the first rod outer rod 51. A plurality of first rod body height adjustment holes 54 with the same size as the through holes on the first rod outer rod 51 are axially evenly arranged on the rod body of the first rod inner rod 52. Axial positioning is performed by matching the first rod body pin 53 with the through hole and the first rod body height adjustment hole 54. The height of the first rod inner rod 52 is adjusted by changing the matching height of the first rod body pin 53 and the first rod body height adjustment hole 54 on the first rod inner rod 52. The height of the first rod body 5 determines the height of the rotating table 4.

[0050] Further optimization scheme, such as Figure 8As shown, the second rod body 6 has a similar structure to the first rod body 5, including a second rod outer rod 61, a second rod inner rod 62 and a second rod body pin 63. Similarly, the second rod outer rod 61 is a hollow tube, and a through hole is opened on the rod body near the top, which runs through the front and back of the rod body. The second rod inner rod 62 is axially inserted into the second rod outer rod 61, and a number of second rod body height adjustment holes 64 with the same size as the through holes on the second rod outer rod 61 are axially evenly arranged on the rod body of the second rod inner rod 62. Axial positioning is performed by cooperating with the second rod body pin 63 and the through hole and the second rod body height adjustment hole 64. The height of the second rod inner rod 62 is adjusted by changing the cooperating height between the second rod body pin 63 and the second rod body height adjustment hole 64 on the second rod inner rod 62. The height of the second rod body 6 determines the height of the cloth roll 10 and can be freely adjusted according to the length of the rib tube 9.

[0051] A horizontal square hole is opened near the top of the second rod 6 , and a square plug plate is inserted into the square hole. Both ends of the square plug plate extend radially outward from the second rod 6 to form a second rod placement platform 65 for placing the cloth roll 10 .

[0052] Further optimization scheme, the diameter of the driving gear 7 and the rib tube fixing gear 8 is determined according to the diameter of the cross-woven rib tube and the number of rib tubes 9. The diameter of the driving gear 7 and the rib tube fixing gear 8 is consistent, and the rib tube fixing gear 8 uses several gears of the same size.

[0053] Further optimization scheme, such as Figure 6 As shown, the clamping unit is arranged at the midpoint of the radius line of each rib tube fixing gear 8. Specifically, in this embodiment, the clamping unit is three square slots opened at the midpoint of the radius line of the rib tube fixing gear 8, namely slot one 14, slot two 15 and slot three 16. Slot two 15 is located in the middle and is the middle slot. The three slots are arranged in a straight line, and the three slots are arranged perpendicular to the radius line of the rib tube fixing gear 8. The cross-section of slot two 15 is square, and the side length is twice the diameter of the rib tube 9. The slot one 14 and slot three 16 located on both sides are of the same size and have a rectangular cross-section. The width is the same as the side length of slot two 15, and the length is slightly larger than the side length of slot two 15. The specific length is determined according to the length of the rib tube fixing bolt 13. The thickness of the partition wall between the two side slots and the middle slot is approximately one-third of the length of the rib tube fixing bolt 13. The center of the partition wall is opened and threaded. The shape of the through hole and the thread form match the rib tube fixing bolt 13.

[0054] The rib tube 9 is placed in the slot 2 15 of the three slots of the rib tube fixing gear 8, and the rib tube fixing bolts 13 on both sides are screwed into the threaded ports to support the rib tube 9 for fixing. The several rib tube fixing gears 8 are engaged in a ring, and the driving gear 7 is engaged with the driving gear 7 of the rib tube 9 closest to the rib tube 9. The driving gear 7 is rotated to drive the rib tube fixing gear 8 to rotate through the gear engagement, and the rib tube 9 is rotated until the circumferential line formed by connecting the adjacent two rib tubes 9 and the centers of the several circumferentially meshed rib tube fixing gears 8 is slightly staggered and offset, so that the adjacent two rib tubes 9 are in an inside-outside staggered position with respect to the circumferential line.

[0055] Further optimization scheme, such as Figure 9 As shown, the exterior of the turntable 4 includes an outer turntable 42, an inner turntable 4 and a turntable roller 41. The turntable 4 is cylindrical as a whole, and its height is slightly greater than the height of the cloth roll 10. The diameter of the outer turntable 42 is consistent with the diameter of the cross-woven rib tube of the cloth strips, and is also consistent with the diameter of the circle formed by the center line of the several rib tube fixing gears 8 after the circumferential meshing. A groove is set between the inner turntable 4 and the outer turntable 42. The turntable roller 41 is cylindrical, with a height slightly smaller than the inner and outer turnstables of the turntable 4, and a diameter consistent with the spacing between the inner and outer turntable grooves of the turntable 4. The center of the turntable 4 is reserved. The hole size is slightly larger than the diameter of the inner rod 52 of the first rod. The middle tube of the cloth roll 10 is inserted into the inner rod 62 of the second rod and placed on the second rod placement platform 65. The cloth roll 10 is partially straightened into a cloth strip, and one side is pasted on the outer platform 42 of the rotating table. The cloth strip is kept tangent to the outer platform 42 of the rotating table. The outer platform 42 of the rotating table is manually rotated until the cloth strip surrounds and fits the outer platform 42 of the rotating table into a ring. The subsequent cloth strip is cut at the initial pasting position, and the cloth strip adhered to one side of the outer platform 42 of the rotating table is removed and glued to the cloth strip on the cut side. It naturally falls into the gap between the several rib tubes 9 below.

[0056] After the cloth roll 10 is cut into a ring and falls into the interlaced gaps of the rib tubes 9, the driving gear 7 is slightly rotated to rotate all the rib tubes 9 toward the position of the cloth roll 10 in the gap until the adjacent rib tubes 9 are slightly staggered in the opposite direction to achieve the effect of interlaced weaving of the cloth rolls 10. Then, the cloth roll 10 is partially straightened into a cloth strip, and one side is pasted on the outer platform 42 of the rotating table until the cloth strip surrounds and fits the outer platform 42 of the rotating table into a ring. After cutting and pasting, it falls naturally, and the driving gear 7 is rotated in the opposite direction to return the rib tube 9 to its initial position. The above steps are repeated until the cloth wraps around the entire rib tube 9. The method can wrap the rib tube 9 quickly and accurately, and the size of the staggered seam can be freely controlled. It is more convenient, quick and efficient, and can be applied to rib tubes 9 of different diameters, different cross-sectional shapes and different lengths. Different quantities and different types of rib tubes 9 can also be selected as materials. The device is simple, easy to install and low in cost. At the same time, it is also suitable for weaving cloth strips of different sizes, and the weaving width can be freely controlled, which effectively reduces manpower and material resources, and can realize factory batch production. It is not limited to the field of engineering technology. Similar cloth strips cross-woven rib tube structure requirements in other fields can also be achieved using this device.

[0057] It should be understood that, in actual applications, the driving gear 7 can be driven by an electric drive mechanism, which can be other drive structures or mechanical devices capable of realizing circumferential motion function / rotational motion / telescopic motion, for example, a stepper motor, a servo motor, a hydraulic cylinder, an electric cylinder, and the like.

[0058] It can be understood that the rib tube base 1, the placement base 2 and the control base 3 are respectively used as bearing and installation structures, and can be set as one, and the shape of the base can be set according to actual production needs. For example, a center hole for installing the first rod body 5 is opened above a base, and several shaft holes 1 for installing the rib tube fixed gear connecting shaft 11 are started on the side of each center hole, and a shaft hole 2 for installing the driving gear connecting shaft 12 is opened on one side of the shaft hole 1, and a shaft hole 3 for installing the second rod body 6 is opened on the other side of the shaft hole 1. The positions of each hole can be reasonably set according to needs.

[0059] An embodiment of the present invention further provides a method for using a circumferentially cross-woven fabric rib tube device, comprising the following steps:

[0060] S1. Rotate the driving gear 7 to drive the rib-tube fixing gear 8 meshing with the driving gear 7 to rotate until two adjacent rib tubes 9 are staggered and crossed.

[0061] S2. Straighten one side of the cloth roll 10 and stick it tangentially to the outer platform 42 of the rotating table. Rotate the outer platform 42 of the rotating table to drive the straightened cloth strip to rotate one circle, so that the cloth strip rotates into a ring.

[0062] S3, cutting and gluing the looped cloth strips in step S2, and then naturally dropping them into the interlaced gaps of the rib tubes 9.

[0063] S4. After the cloth strips in step S3 fall into the gaps between the interlaced rib tubes 9, the driving gear 7 in step S1 is rotated in the opposite direction to drive the rib tubes 9 to rotate in the opposite direction against the cloth strips, so that the rib tubes 9 are interlaced in the opposite direction.

[0064] S5. Repeat steps S2, S3, and S4 until the cloth strips are cross-woven around the entire rib tube 9, and the rib tube is formed by the circumferential cross-woven cloth strips.

[0065] Any details not provided in the present invention are all conventional technical means well known to those skilled in the art.
