Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a CFRP hanger installation guide device. Background Technology

[0002] During the installation of CFRP (Cable Reinforced Plastic) hangers for tied arch bridges, the hangers are often fabricated on-site. Upon arrival, the reinforcement is already in place, and the tensioning and fixing ends are installed. In this case, due to slight twisting of the cable, the anchor head and cable of the CFRP hanger are prone to friction with the outer casing during installation and lowering, potentially causing jamming or damage to the anchor head. To ensure structural safety and quality, it is essential to minimize contact and friction between the anchor head and cable of the CFRP hanger and the outer casing. Utility Model Content

[0003] This invention provides a CFRP hanger installation guide device that can overcome some or all the defects of the prior art.

[0004] According to the present invention, a CFRP hanger installation guide device includes a sleeve connected to the anchoring end of the CFRP hanger. The sleeve includes a fixing part and a connecting sleeve. The anchor head of the anchoring end of the CFRP hanger is located inside the connecting sleeve. A guide auxiliary rope is provided at one end of the sleeve.

[0005] This invention relates to a method for constructing CFRP (Cable Reinforced Plastic) hangers for tied arch bridges. The process involves removing the mounting nut from the anchoring end of the CFRP hanger, installing a guide device on the anchoring end, and tightening it for reinforcement. The anchor head is completely enclosed by the guide device. A truck crane is used to lift the tensioning end of the CFRP hanger, raising it above the hanger's outer sleeve. The device body at the anchoring end is aligned with the outer sleeve, and its position is adjusted to place it inside the sleeve. The CFRP hanger is then slowly lowered. Once the guide rope protrudes from the bottom opening of the outer sleeve, the guide device body and the CFRP hanger are manually pulled to guide their descent until the anchoring end protrudes from the sleeve. The device body is then removed, the mounting nut on the anchoring end is reinstalled, and finally, the anchoring end of the CFRP hanger is secured.

[0006] The guide device ensures the safety and quality of CFRP rod installation, reduces contact and friction between the CFRP rod anchoring end and the cable body and the outer sleeve. The guide device is easy to install and remove, and it can be reused, making it economical and environmentally friendly.

[0007] Preferably, the fixing part has internal threads that connect to the anchoring end of the CFRP hanger.

[0008] This invention provides a CFRP (Cable Reinforced Plastic) rod anchoring end that includes a mounting nut. Before installing the guide device, the mounting nut needs to be removed. The internal threads of the fixing part match the threads of the removed mounting nut on the CFRP rod anchoring end. This threaded connection provides a robust mechanical connection, ensuring the stability of the connection between the CFRP rod anchoring end and the guide device, and preventing loosening during installation or use. Simultaneously, the threaded connection facilitates quick disassembly for inspection or maintenance, making replacement or repair easier.

[0009] Preferably, a conical guide head is provided between the sleeve and the guide auxiliary rope, with the bottom of the conical guide head connected to the sleeve and the apex of the conical guide head connected to the guide auxiliary rope.

[0010] This invention utilizes a conical guide head design to provide excellent guidance during the installation of CFRP (Cable Reinforced Plastic) booms, helping them smoothly enter the outer sleeve and reducing friction and damage caused by directional deviations. During the CFRP boom's descent, the conical guide head minimizes jamming caused by friction between the cable and the outer sleeve, ensuring the CFRP boom is smoothly installed in place.

[0011] Preferably, a nut is welded to the apex of the guide head, and the guide auxiliary rope passes through the nut and is secured by multiple rope clips on the rope body.

[0012] This invention utilizes a guide rope that passes through a nut, allowing operators to precisely control the position of the CFRP boom during installation, ensuring it is installed smoothly along the predetermined path. The rope clamp is detachable, making inspection and maintenance of the guide rope more convenient. Furthermore, adjusting the position of the rope clamp allows for adaptation to different CFRP boom lengths and installation requirements.

[0013] Preferably, the fixing part and the connecting sleeve, as well as the connecting sleeve and the guide head, are welded together.

[0014] This invention provides a robust mechanical connection through welding, ensuring that the guide device will not loosen or detach during installation and use. Welding reduces the number of parts requiring individual assembly, simplifies the installation process, and saves installation time and labor costs.

[0015] Preferably, the fixing part and the connecting sleeve are cylinders with the same outer diameter, and their outer diameter is larger than the maximum outer diameter of the CFRP hanger and smaller than the inner diameter of the outer sleeve.

[0016] The outer diameter design of the fixing part and connecting rod ensures that the guide device can be properly matched with the CFRP hanger and the outer sleeve. It is neither too large to pass through the outer sleeve nor too small to protect the hanger well, thus increasing the adaptability of the guide device. Attached Figure Description

[0027] like Figure 1-8 As shown, this embodiment provides a CFRP rod installation guide device, which includes a sleeve 100 connected to the anchoring end 110 of the CFRP rod. The sleeve 100 includes a fixing part 101 and a connecting sleeve 102. The anchor head 160 of the anchoring end 110 of the CFRP rod is located inside the connecting sleeve 102. One end of the sleeve 100 is provided with a guide auxiliary rope 104.

[0028] In this embodiment, when installing the CFRP hanger 130 in the tied arch bridge, the mounting nut 150 on the anchoring end 110 of the CFRP hanger is removed, and the guide device is installed on the anchoring end 110 of the CFRP hanger and tightened for reinforcement. The anchor head 160 is completely wrapped by the guide device. The tensioning end 140 of the CFRP hanger is lifted by a truck crane, and the CFRP hanger 130 is lifted. The CFRP hanger 130 is lifted above the hanger outer sleeve 410, and the device body 100 at the anchoring end 110 of the CFRP hanger is aligned with the hanger outer sleeve 410. Then, the position is adjusted and the device body 100 is placed inside the hanger outer sleeve 410. Slowly lower the CFRP boom 130. When the guide rope 104 is exposed at the bottom opening of the boom outer tube 410, manually pull the guide device body 100 and the CFRP boom 130 to guide their descent direction until the anchor end 110 is exposed through the outer tube 410. Remove the device body 100, reinstall the mounting nut 150 on the CFRP boom anchor end 110, and finally fix the CFRP boom anchor end 110.

[0029] The guide device ensures the safety and quality of CFRP rod 130 installation, reduces contact and friction between the CFRP rod anchor end 110 and cable body 120 and outer sleeve 410, and the guide device is easy to install and disassemble and can be reused, which is economical and environmentally friendly.

[0030] In this embodiment, the fixing part 101 has internal threads and is threadedly connected to the anchoring end 110 of the CFRP rod.

[0031] In this embodiment, the CFRP rod anchoring end 110 includes a mounting nut 150. Before installing the guide device, the mounting nut 150 needs to be removed. The threads inside the fixing part 101 match the threads of the removed mounting nut 150 on the CFRP rod anchoring end 110. The threaded connection provides a robust mechanical connection, ensuring the stability of the connection between the CFRP rod anchoring end 110 and the guide device, preventing loosening during installation or use. Simultaneously, the threaded connection facilitates quick disassembly for inspection or maintenance, making replacement or repair easier.

[0032] In this embodiment, a conical guide head 103 is provided between the sleeve 100 and the guide auxiliary rope 104. The bottom of the conical guide head 103 is connected to the sleeve 100, and the top of the conical guide head 103 is connected to the guide auxiliary rope 104.

[0033] In this embodiment, the conical guide head 103 design provides excellent guidance during the installation of the CFRP boom 130, helping it smoothly enter the outer sleeve 410 and reducing friction and damage caused by directional deviations. During the descent of the CFRP boom 130, the conical guide head 103 reduces jamming caused by friction between the cable 120 and the outer sleeve 410, ensuring the CFRP boom 130 is smoothly installed in place.

[0034] In this embodiment, a nut 210 is welded to the apex of the guide head 103, and the guide auxiliary rope 104 passes through the nut 210 and is fixed by multiple rope clips 220 on the rope body.

[0035] In this embodiment, the guide rope 104 passes through the nut 210, allowing the operator to precisely control the position of the CFRP boom 130 during installation, ensuring that the CFRP boom 130 is installed smoothly along the predetermined path. The rope clamp 220 is detachable, making it easier to inspect and maintain the guide rope 104. Furthermore, by adjusting the position of the rope clamp 220, it can accommodate CFRP booms 130 of different lengths and various installation requirements.

[0036] In this embodiment, the fixing part 101 and the connecting sleeve 102, as well as the connecting sleeve 102 and the guide head 103, are welded together.

[0037] In this embodiment, the welded connection provides a robust mechanical link, ensuring that the guide device will not loosen or detach during installation and use. The welded connection reduces the number of parts requiring individual assembly, simplifies the installation process, and saves installation time and labor costs.

[0038] In this embodiment, the fixing part 101 and the connecting sleeve 102 are cylinders with the same outer diameter, and their outer diameter is larger than the maximum outer diameter of the CFRP hanger 130 and smaller than the inner diameter of the outer sleeve 410.

[0039] In this embodiment, the outer diameter design of the fixing part 101 and the connecting rod 102 ensures that the guide device can properly match the CFRP rod 130 and the outer sleeve 410. It is neither too large to pass through the outer sleeve 410, nor too small to protect the rod well, thus increasing the adaptability of the guide device.

[0040] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
