Description

Technical Field

[0001] The invention relates to the field of prestressed cables, in particular to a tower prestressed cable connection structure for building construction. Background Art

[0002] The two sections of prestressed cables need to be fixed by a connecting structure and adjusted according to the required position and number of the prestressed cables to meet the needs of the prestressed cables. However, for the sake of reliability and connection strength, the existing connection structure of the prestressed cables generally connects two or more prestressed cables together through cable clamps. Although this connection method can achieve rapid connection and tensioning of the prestressed cables, it still requires manual splicing of the connecting ends of the two sections of prestressed cables, which is too inconvenient. In addition, when the prestressed cables are subsequently replaced or maintained, the two sections of prestressed cables still need to be disassembled again, which is too inconvenient. Summary of the Invention

[0003] The present invention provides a tower prestressed cable connection structure for building construction, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A tower prestressed cable connection structure for construction includes a connection structure body and a fixed arm for connecting the prestressed cables. The prestressed cables extend through the connection structure body and into the fixed arm. A fastener is fixed to the connection end between the connection structure body and the fixed object. The connection structure body includes a twisting channel and a twisting plate. The twisting channel extends to the upper and lower ends of the connection structure body, and the twisting plate is arranged near the middle of the connection structure body. When the prestressed cables are connected, the prestressed cables extend through the twisting channel into the connection structure body and pass through the twisting plate during the extension process.

[0006] The twisted plate is arranged in an inclined manner, and the middle portion of the twisted plate is in a curved structure;

[0007] An L-shaped hole is provided in the fixed arm, and both ends of the L-shaped hole extend to the lower end and side of the fixed arm respectively. The prestressed cable extends from the lower end of the L-shaped hole into the fixed arm and extends outward through the upper end of the L-shaped hole. A card slot is provided on the side of the connecting structure body close to the fixed arm. The fastener is embedded in the card slot and abuts against the surface of the prestressed cable extending outside the fixed arm.

[0008] A preferred technical solution, the twisted channel includes a first channel and a second channel, one end of the first channel extends to the upper end of the connecting structure body, and the other end extends to the surface of the connecting structure body near the middle, one end of the second channel extends to the lower end of the connecting structure body, and the other end extends to the surface of the connecting structure body near the middle, the surface of the twisted plate is provided with a through hole for the prestressed cable to pass through, the level of the through hole is higher than the level of one end near the surface of the middle of the connecting structure body;

[0009] The prestressed cable extends through the second channel, the through hole and the first channel in sequence, and the surface of the prestressed cable near the through hole presents a twisted structure.

[0010] In a preferred technical solution, a lower portion of the channel is bent toward a side away from the corresponding twisted plate.

[0011] A preferred technical solution, the fastening part includes a buckle plate 1, a connecting structure body and a clamping plate. The buckle plate set is arranged outside the fixed arm and is pressed against the surface of the prestressed cable through a clamping groove set at its lower end. The buckle plate 2 is embedded in the clamping groove. The buckle plate 1 and the buckle plate 2 are fixed by a circular array of clamping plates.

[0012] A preferred technical solution is that the upper and lower ends of the connection structure body are respectively provided with bolt grooves for injecting chemical bolts in a circular array. The diameter of the bolt groove at one end close to the middle of the connection structure body is larger than that at the other end. Before the prestressed cable is extended into the bolt groove for fixation, the chemical bolt must first be placed in the bolt groove, and the chemical bolt is broken by inserting the prestressed cable, and the chemical agent in the chemical bolt is used to solidify and fix the end of the prestressed cable.

[0013] In a preferred technical solution, when two connection structure bodies need to be connected, the prestressed cables in the two connection structure bodies are respectively extended into bolt grooves provided on the surfaces of the corresponding connection structure bodies, the first channel and the second channel at both ends of the connection structure body are respectively spaced apart from the adjacent bolt grooves, and the prestressed cables in the two connection structure bodies are staggered.

[0014] The fastening member includes a card plate and a symmetrical second card plate. A second card plate is clamped in each of the card slots provided at the adjacent ends of the two connecting structure bodies, and the two second card plates are fixed together by the card plate.

[0015] Compared with the existing technology, this technical solution has the following advantages:

[0016] The twisted channel is a key part of the connecting structure body. Its two ends extend to the upper and lower ends of the connecting structure body respectively, providing a through channel for the prestressed cable. The prestressed cable enters from the lower end of the twisted channel and extends upward along the channel. During the extension process, the prestressed cable will pass through the twisted plate body. The twisted plate body is set at an angle. This inclination angle enables the prestressed cable to have a certain guiding effect when passing through. At the same time, the middle part of the twisted plate body is a curved structure. This curved design further increases the contact area and friction between the prestressed cable and the twisted plate body. When the prestressed cable passes through the twisted plate body, the curved middle structure will exert a certain constraint force on it, so that the prestressed cable is initially fixed in the channel to prevent it from sliding in subsequent operations.

[0029] like Figures 1 to 7As shown, the present invention proposes a tower prestressed cable connection structure for construction, including a connection structure body 2 and a fixed arm 1 for connecting a prestressed cable 100. The prestressed cable 100 passes through the connection structure body 2 and extends into the fixed arm 1. A fastener 3 is fixed to the connection end of the connection structure body 2 and the fixed object. The connection structure body 2 includes a twisting channel 21 and a twisting plate 22. The twisting channel 21 extends to the upper and lower ends of the connection structure body 2, and the twisting plate 22 is arranged near the middle of the connection structure body 2. When the prestressed cable 100 is connected, the prestressed cable 100 extends into the connection structure body 2 through the twisting channel 21 and passes through the twisting plate 22 during the extension process.

[0030] The twisted plate 22 is arranged in an inclined manner, and the middle portion of the twisted plate 22 is a curved structure;

[0031] An L-shaped hole 11 is provided in the fixed arm 1, and the two ends of the L-shaped hole 11 extend to the lower end and the side of the fixed arm 1 respectively. The prestressed cable 100 extends from the lower end of the L-shaped hole 11 into the fixed arm 1 and extends outward through the upper end of the L-shaped hole 11. A card slot 1 23 is provided on the side of the connecting structure body 2 close to the fixed arm 1. The fastener 3 is embedded in the card slot 1 23 and abuts against the surface of the prestressed cable 100 extending outside the fixed arm 1.

[0032] As can be seen from the above, the twisted channel 21 is a key part of the connecting structure body 2. Its two ends extend to the upper and lower ends of the connecting structure body 2 respectively, providing a through channel for the prestressed cable 100. The prestressed cable 100 enters from the lower end of the twisted channel 21 and extends upward along the channel. During the extension process, the prestressed cable 100 will pass through the twisted plate 22. The twisted plate 22 is set at an angle. This inclination angle enables the prestressed cable 100 to have a certain guiding effect when passing through. At the same time, the middle part of the twisted plate 22 is a curved structure. This curved design further increases the contact area and friction between the prestressed cable 100 and the twisted plate 22. When the prestressed cable 100 passes through the twisted plate 22, the curved middle structure will produce a certain constraint force on it, so that the prestressed cable 100 is initially fixed in the channel to prevent it from sliding in subsequent operations.

[0033] Then, the prestressed cable 100 continues to extend upward along the twisted channel 21 to the L-shaped hole 11 in the fixed arm 1. The special design of the L-shaped hole 11 plays a key locking role. The prestressed cable 100 enters the fixed arm 1 from the lower end of the L-shaped hole 11, and then extends outward through the upper end of the L-shaped hole 11. Since the two ends of the L-shaped hole 11 extend to the lower end and the side of the fixed arm 1 respectively, this L-shaped structure allows the prestressed cable 100 to form a "hook-like" state in the fixed arm 1. When the prestressed cable 100 extends to the upper end of the L-shaped hole 11 and extends outward, the part thereof in the L-shaped hole 11 will be constrained by the side of the fixed arm 1, thereby achieving further locking of the prestressed cable 100.

[0034] In addition, a card slot 23 is provided on the side of the connection structure body 2 close to the fixed arm 1. The fastener 3 is embedded in the card slot 23 and abuts against the surface of the prestressed cable 100 extending outside the fixed arm 1. This setting of the fastener 3 plays an auxiliary fastening role. It further enhances the stability of the prestressed cable 100 in the connection structure by abutting against the surface of the prestressed cable 100. This multi-layer locking and fastening mechanism enables the prestressed cable 100 to be firmly fixed in the connection structure without the need for manual splicing operations. At the same time, this structural design also facilitates subsequent replacement and maintenance without the need to disassemble the two sections of prestressed cable again, which greatly improves work efficiency and solves the inconvenience mentioned in the background technology.

[0035] It should be explained that in the tower prestressed cable connection structure of the present invention, the twisting direction of the prestressed cable 100 combined with the special design of the connection structure provides significant beneficial effects for solving the technical problems mentioned in the background technology.

[0036] First, as the prestressed cable 100 passes through the twisted channel 21 and twisted plate 22, its twisting direction interacts with the structure of the channel and plate. The extension direction of the twisted channel 21 and the tilted and curved design of the twisted plate 22 guide and constrain the prestressed cable 100 along a predetermined path as it enters the connection structure body 2. This guidance prevents the prestressed cable 100 from misaligning or shifting when entering the connection structure, thereby reducing the need for manual adjustment of the prestressed cable position and improving the convenience of the connection process.

[0037] Secondly, the twisting direction of the prestressed cables 100 cooperates with the curved midsection of the twisted plate 22, further enhancing the locking and securing effect of the prestressed cables. As the prestressed cables 100 pass through the twisted plate 22, their twisting direction creates a closer contact between the cables and the plate, significantly increasing friction. This increased friction securely secures the prestressed cables 100 in the connection structure, eliminating the need for additional splicing. This not only simplifies the connection process but also reduces the risk of loosening or failure due to improper splicing.

[0038] In addition, this locking effect not only ensures the stability of the prestressed cables 100 in the connection structure, but also makes subsequent replacement and maintenance more convenient, without the need to splice the prestressed cables 100 during each maintenance.

[0039] Furthermore, the twisted channel 21 includes a first channel 211 and a second channel 212. One end of the first channel 211 extends to the upper end of the connecting structure body 2, and the other end extends to the surface of the connecting structure body 2 near the middle. One end of the second channel 212 extends to the lower end of the connecting structure body 2, and the other end extends to the surface of the connecting structure body 2 near the middle. The surface of the twisted plate 22 is provided with a through hole 221 for the prestressed cable 100 to pass through. The horizontal height of the through hole 221 is higher than the horizontal height of one end of the through hole 221 near the surface of the middle of the connecting structure body 2.

[0040] The prestressed cable 100 extends through the second channel 212 , the through hole 221 and the first channel 211 in sequence. The surface of the prestressed cable 100 near the through hole 221 is twisted, and the lower portion of the first channel 211 is bent toward the side away from the corresponding twisted plate 22 .

[0041] Dividing the twisted channel 21 into channel 1 211 and channel 2 212 can provide a more optimized guiding path for the prestressed cable 100. Channel 2 212 extends from the lower end of the connection structure body 2 to the surface near the middle, while channel 1 211 extends from the upper end of the connection structure body 2 to the surface near the middle. This segmented design allows the prestressed cable 100 to enter the connection structure body 2 from the lower end, pass through channel 2 212 to reach the twisted plate 22, and then extend to the upper end of the connection structure body 2 through channel 1 211. Such a path design can ensure that the prestressed cable 100 can pass through the twisted plate 22 smoothly and smoothly when entering the connection structure, avoiding cable distortion or jamming caused by an excessively long channel or a single path.

[0042] The segmented design enables the prestressed cable 100 to better interact with the structure of the twisted plate body 22 when passing through the twisted plate body 22. The segmented setting of channel 2 212 and channel 1 211 enables the prestressed cable 100 to be better constrained and fixed when passing through the twisted plate body 22. In particular, the two ends of channel 1 211 and channel 2 212 extend to the upper and lower ends of the connecting structure body 2 respectively. This design enables the prestressed cable 100 to form a "double constraint" state in the connecting structure body 2, further enhancing the locking effect of the prestressed cable 100.

[0043] Furthermore, when the prestressed cable 100 needs to be withdrawn, the operator can use a tool or manually lift or pull the prestressed cable 100 exposed on the surface of the connecting structure body 2. Due to the curved design of the lower portion of the channel 1 211, the prestressed cable 100 can be more easily removed from the channel 1 211 when being lifted or pulled without excessive obstruction.

[0044] In addition, the fastener 3 includes a buckle plate 31, a connecting structure body 2 and a clamping plate 33. The buckle plate 31 is mounted on the outside of the fixed arm 1 and is pressed against the surface of the prestressed cable 100 through a clamping groove 311 set at its lower end. The buckle plate 32 is embedded in the clamping groove 23. The buckle plate 31 and the buckle plate 32 are fixed by the clamping plate 33 in a ring array.

[0045] Furthermore, the upper and lower ends of the connection structure body 2 are respectively provided with bolt grooves 24 for injecting chemical bolts in a circular array. The diameter of the bolt groove 24 at one end close to the middle of the connection structure body 2 is larger than that at the other end. Before the prestressed cable 100 is extended into the bolt groove 24 for fixation, the chemical bolt must first be placed in the bolt groove 24, and the chemical bolt is broken by inserting the prestressed cable 100, and the chemical agent in the chemical bolt is used to solidify and fix the end of the prestressed cable 100. Example 2

[0046] Based on the above, when two connection structure bodies 2 need to be connected, the prestressed cables 100 in the two connection structure bodies 2 are respectively extended into the bolt grooves 24 provided on the surfaces of the connection structure bodies 2. The first channel 211 and the second channel 212 at both ends of the connection structure body 2 are respectively spaced apart from the adjacent bolt grooves 24, and the prestressed cables 100 in the two connection structure bodies 2 are staggered.

[0047] The fastening member 3 in this embodiment includes a card plate 33 and a symmetrical second card plate 32. A second card plate 32 is clamped in each of the card slots 23 provided at the adjacent ends of the two connecting structure bodies 2. The two second card plates 32 are fixed together by the card plate 33.

[0048] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
