Description

Technical Field

[0001] The present invention relates to the field of composite material processing for structural engineering, and in particular to a rib tube device with cloth strips wound around it in a circumferential cross direction and a use method thereof. Background Art

[0002] In the field of structural engineering, seawater sand concrete has become an emerging building material due to the shortage of fresh water and river sand resources and the impact on the ecological environment. However, the corrosion of this concrete to traditional steel may lead to structural safety problems. Therefore, people began to seek new building materials compatible with seawater sand concrete. Fiber reinforced polymer (FRP) composites are regarded as ideal alternative materials due to their advantages such as light weight, high strength, good corrosion resistance and designability, especially for marine engineering structures.

[0003] FRP pipes can significantly improve the bearing capacity and ductility of the structure through circumferential fiber reinforcement. At the same time, they can be used as permanent formwork, simplifying the construction process and improving the durability of the structure. However, circumferential fiber FRP pipes are insufficient in resisting lateral forces and usually need to be used in conjunction with longitudinal reinforcement to resist eccentric pressure or horizontal loads. At present, circumferential fiber FRP pipes and longitudinal reinforcements are usually separated and difficult to form into one piece. Even if they are bonded by gluing, the reinforcement is often exposed, affecting the overall quality of the pipe.

[0004] In order to solve this problem, a new type of FRP cloth circumferential cross-woven reinforcement tube has been developed. This tube is made of cylindrical reinforcements arranged at equal intervals, and then cross-woven by 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 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 cloth strip circumferentially cross-wrapped rib tube device and a method of using the same to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 rib tube device for circumferentially cross-wrapping a cloth strip, comprising a rib tube base 1, a placement base 2 and a control base 3, wherein the three bases have the same height, that is, 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 above the control base 3, and the driving gear 7 is supported at the upper center of the control base 3 through 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 connected to the center of the upper part of the rib tube base 1. A rotating platform 4 is rotatably connected to the telescopic end of the first rod 5 (the end away from the rib tube base 1). The rotating platform 4 is cylindrical, and its outer circumference is used to stick and fix the cloth roll 10. A plurality of even-numbered rib tube fixing gears 8 are evenly distributed in an annular manner on the rib tube base 1 on the circumference of the first rod 5. The rib tube fixing gears 8 are meshed with each other, and one of the rib tube fixing gears 8 is meshed with the driving gear 7. The rib tube fixing gears 8 rotate on the rib tube base 1 through the rib tube fixing gear connecting shaft 11. Driven by the driving gear 7, the rib tube fixing gears 8 rotate synchronously in alternating directions. A clamping unit for fixing and installing the rib tube 9 is provided on each rib tube fixing gear 8. A second rod 6 is fixedly connected to the center of the upper part of the placement base 2. The height of the second rod 6 is adjustable. 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 for supporting the cloth roll 10 from the bottom is fixedly connected to the position of the rod near the top end.

[0044] Before using the above-mentioned cloth strip annular cross-winding rib tube device, place the cloth roll 10 on the second rod body placement platform 65 in advance, the cloth roll 10 is sleeved with the second rod body 6 and can rotate freely, and one end of the cloth strip is pasted on the outer periphery of the rotating platform 4; each rib tube 9 is fixed on each of the rib tube fixing gears 8. The rib tube fixing gear 8 is driven to rotate by rotating the driving gear 7, and the rib tube 9 fixed on each rib tube fixing gear 8 rotates with the rotation of the rib tube fixing gear 8. When two adjacent rib tubes 9 are staggered and crossed, the cloth strip that is straightened and pasted on the outside of the rotating platform 4 is wound around the rib tube 9 with the rotation of the rotating platform 4, and the cloth strip falls into the interlaced gap of the rib tube 9. The driving gear 7 is rotated in the reverse direction to drive the rib tube 9 to support the cloth strip and rotate in the reverse direction, so that the rib tube 9 is interlaced in the reverse direction, so that the cloth strip achieves the effect of cross-weaving the rib tube, and the above operation is repeated until the cloth strip cross-weaving rib tube is 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 rib tube base 1 is tangent to the mounting base 2 and the control base 3 respectively; the rib tube base 1 is coaxial with the cross-woven rib tube of the cloth strip, and an axial hole for installing the first rod body 5 is reserved in the center of the rib tube base 1, and axial holes with the same number as the rib tube 9 are reserved on the outer peripheral side of the axial hole, and these outer axial holes are used to install the rib tube fixing gear connecting shaft 11; an axial hole for installing the second rod body 6 is reserved in the center of the mounting base 2; and an axial hole for installing the active 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 with 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 with the control base 3, and the diameter of the lower end is adapted to the diameter 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 latch 53. The first rod outer rod 51 is a hollow tube, and a through hole penetrating the front and rear of the rod body is opened on the rod body near the top. 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 the cooperation of the first rod body latch 53 with the through holes and the first rod body height adjustment hole 54. The height of the first rod inner rod 52 is adjusted by changing the cooperation height between the first rod body latch 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 is similar to the first rod body 5 in structure, including a second rod outer rod 61, a second rod inner rod 62 and a second rod body latch 63. Similarly, the second rod outer rod 61 is a hollow tube, and a through hole penetrating the front and back of the rod body is opened on the rod body near the top. The second rod inner rod 62 is axially inserted into the second rod outer rod 61. A plurality 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 the cooperation of the second rod body latch 63 with 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 cooperation height between the second rod body latch 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 body 6 , a square plug plate is inserted into the square hole, and both ends of the square plug plate extend radially outward from the second rod body 6 to form a second rod body placement platform 65 for placing the cloth roll 10 .

[0052] According to a further optimization scheme, the diameters of the driving gear 7 and the rib tube fixing gear 8 are determined according to the diameter of the cross-woven rib tube and the number of rib tubes 9. The diameters of the driving gear 7 and the rib tube fixing gear 8 are 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 the present 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-sectional shape. 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, and 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 second slot 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 in annular meshing, and the driving gear 7 is meshed 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 meshing, and the rib tube 9 is rotated until the circumferential line formed by connecting the centers of the two adjacent rib tubes 9 and the several circumferentially meshing rib tube fixing gears 8 is slightly staggered and offset, so that the two adjacent rib tubes 9 are in an inner and outer staggered position with respect to the circumferential line.

[0055] Further optimization scheme, such as Fig. 9 As shown, the exterior of the rotating table 4 includes an outer rotating table 42, an inner rotating table 4 and a rotating table roller 41. The rotating table 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 rotating table 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 plurality of rib tube fixing gears 8 after the circumferential meshing. A groove is set between the inner rotating table 4 and the outer rotating table 42. The rotating table roller 41 is cylindrical, and its height is slightly smaller than the inner and outer rotating tables of the rotating table 4. The diameter is consistent with the spacing between the inner and outer rotating table grooves of the rotating table 4. The center of the rotating table 4 has a reserved hole The hole size is slightly larger than the diameter of the first rod body inner rod 52, the middle tube of the cloth roll 10 is inserted into the second rod body inner rod 62, and placed on the second rod body placement platform 65, the cloth roll 10 is partially straightened into a cloth strip, one side of which is pasted on the rotating table outer platform 42, the cloth strip is kept tangent to the rotating table outer platform 42, and the rotating table outer platform 42 is manually rotated until the cloth strip surrounds and fits the rotating table outer platform 42 to form a ring, and the subsequent rolled-in cloth strip is cut at the initial pasting position, and the cloth strip pasted on one side of the rotating table outer platform 42 is removed, and it is pasted with the cloth strip on the cut side, and naturally falls into the interlaced gaps of the plurality of rib tubes 9 below.

[0056] After the cloth roll 10 is cut into a ring and falls into the interlaced gaps of the plurality of 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 roll 10. The cloth roll 10 is then partially straightened into a cloth strip, and one side is pasted to the outer platform 42 of the rotating table until the cloth strip surrounds and fits the outer platform 42 of the rotating table to form a ring. After the cloth strip is cut and pasted and falls naturally, 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 with high accuracy, and the size of the staggered seam can be freely controlled, which is more convenient, quick and efficient. It can be applied to rib tubes 9 of different diameters, different cross-sectional shapes and different lengths, and different numbers and types of rib tubes 9 can also be selected as materials. The device is simple, easy to install and low in cost. 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, and similar cloth strip cross-woven rib tube structure requirements in other fields can also be achieved using this device.

[0057] It should be understood that, in practical 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 can be set as one as the bearing and installation structures respectively, 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] The embodiment of the present invention also 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 so that the strips naturally fall into the interlaced gaps between the rib tubes 9.

[0064] S5, repeat the operations of steps S2, S3, and S4 until the cloth strips are cross-wrapped around the entire rib tube 9, and the rib tube is formed by the circumferential cross-weaving of the cloth strips.
