Description

Technical Field

[0001] This utility model belongs to the field of anchorage structure technology, specifically, it relates to a steel bar anchorage structure for composite columns. Background Technology

[0002] Anchored structures refer to structural forms that connect a structure to the surrounding soil or rock through anchor bolts or anchor cables to enhance its stability and load-bearing capacity. Its main components include: anchor head: the part that connects the structure to the anchor bolt, responsible for transmitting the force to the anchor bolt; anchor body: closely connected to the soil and rock layer, responsible for transmitting the force of the tie rod to the stable stratum through frictional resistance.

[0003] The prior art patent document CN206476683U discloses an anchoring structure in which the helical blades are fixed to the anchor body, making them less prone to detachment due to external forces during rotation. The rods facilitate the rapid and efficient transmission of torque to all parts of the helical blades. A limiting groove is excavated in the ground, and the anchor body is vertically inserted into the limiting groove. The rotary drive device is fixed to the bottom of the limiting groove and drives the anchor body to rotate. Located below ground level, the rotary drive device is unlikely to obstruct the winch during its movement. The limiting groove is divided into a soil holding box and a power unit, separated by the soil holding box. The bottom of the soil holding box is located in the middle of the limiting groove. The rotary drive device is located in the power unit, independent of the soil holding box and less susceptible to contamination from the soil within it. The helical blades are located inside the soil holding box, and the length of the central axis of the helical blades is less than the length of the soil holding box. The depth of the container ensures sufficient space for the soil to move when the spiral blades rotate. The rotary drive device is connected to the bottom of the limiting groove via a spring. When the rotary drive device rotates the anchor body, the spiral blades drive the anchor body up and down. At this time, the spring deforms, allowing the rotary drive device to move up and down with the anchor body. The winding assembly includes a reel coaxially arranged with the anchor body and limiting plates located at both ends of the reel in the vertical direction. When the anchor body rotates, the reel rotates accordingly, driving the connecting cable to be wound up and down. The limiting plates on the reel reduce the possibility of the connecting cable falling off the reel. A pulley is provided at the bottom of the winch, and a groove is provided on the ground to accommodate the pulley. The pulley facilitates pushing the winch to make relative displacement when the length of the connecting cable changes. When the winch is subjected to tension, the tension is directed towards the side of the winch away from the anchor body, tightening the connecting cable. This allows for convenient and quick changes in the relative position between the winch and the ground.

[0004] However, due to the poor protection and fixing capabilities of the existing anchoring structure in the CN206476683U patent, the anchoring structure on the composite column cannot be used for protection as needed during actual use, making it inconvenient to fix the anchoring structure on the composite column and affecting the anchoring effect of the anchoring structure.

[0033] Working principle

[0034] In use, the reinforcing bars are fixed by the longitudinal cylinder 7 and the sealing gasket 8. When the reinforcing bars pass through the longitudinal cylinder, the sealing gasket 8 fills the gap between the reinforcing bars and the cylinder wall through elastic compression, achieving a seal and preventing water from seeping into the anchoring structure. The connecting screw cylinder 9 connects the reinforcing bars installed on the longitudinal cylinder 7 to the anchoring top plate 1, enhancing the connection strength between the reinforcing bars and the anchoring structure and preventing the reinforcing bars from loosening. The waterproof coating fiber layer 10 and polyamide fiber layer 11 form the first waterproof barrier. The dense fiber structure blocks water penetration, improving the waterproof effect of the anchoring structure of the reinforcing bars on the composite column. The cellulose nanofiber layer 12 and polypropylene fiber layer 13 further enhance the waterproofness. At the same time, the high specific surface area of ​​the nanofibers enhances the coating adhesion. The thermoplastic elastomer 14 and high elastic fiber layer 15 give the structure resistance to deformation and can buffer the stress caused by external loads. The carbon fiber layer 16 serves as a high-strength support layer. Its excellent tensile strength enhances the overall load-bearing capacity of the anchoring structure, preventing structural cracking and further improving the strength of the anchoring structure of the reinforcing bars on the composite column.

[0035] The top anchor plate 1 and the bottom anchor plate 6 are respectively connected by bolts 20 passing through the connecting screw holes 18 of each plate and then tightened with connecting nuts 19, so as to achieve rigid fixation of the top anchor plate 1 to the first middle anchor plate 4 and the bottom anchor plate 6 to the second middle anchor plate 5, forming a stable layered structure. Pressing the fixing button 21 on the first middle anchor plate 4 pushes the block 22 to drive the movable locking block 25 to compress the return spring 24 downward, and the movable locking block 25 slides into the limiting groove at the top of the second middle anchor plate 5. After releasing the button, the return spring 24 elastically returns to its original position, pushes the movable locking block 25 out and engages it in the connecting screw hole 18 of the first middle anchor plate 4, so as to achieve quick positioning and splicing of adjacent plates, and the installation can be completed without additional tools. The buffer rubber pad 2 between each plate absorbs the impact of external load through elastic deformation, reducing the connection loosening caused by structural vibration. The transverse groove 3 at the bottom of the buffer rubber pad 2 provides a transverse installation channel for the reinforcing bars, which facilitates the insertion and fixing of the reinforcing bars and optimizes the convenience of construction.
