Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of anchorage fastening structure, and particularly relates to a fabricated anchorage fastening structure for heavy pipeline support of a steel structure workshop. BACKGROUND

[0002] The steel structure workshop is widely used in the mechanical manufacturing, chemical industry, energy industry and the like due to the advantages of large span, short construction period, high space utilization and the like. A large number of heavy pipelines such as water supply and drainage main pipes, heating and air conditioning trunk lines and process medium conveying pipelines are usually laid in the workshop, and the weight of a single section of the pipelines can reach hundreds of kilograms or even several tons. The long-term stable support of the pipelines depends on the reliable connection of anchorage with the steel beam.

[0003] At present, the fixing of the heavy pipeline and the steel beam usually adopts a single anchorage structure. There are two common forms. One is to directly fasten a metal clamp on the flange of the steel beam through a single group of high-strength bolts, and the pipeline is fixed in the clamp through bolts or buckles. The other is to weld a single metal support rod on the web of the steel beam at one end, and connect the other end with the pipeline through a flange or a clamp. The core commonality of the above two structures is that the weight of the pipeline, the running vibration load (such as fluid impact in the pipeline, equipment linkage vibration) and the temperature deformation stress (such as pipeline expansion caused by environmental temperature difference) are all concentrated to the connection joint of the single anchorage and the steel beam.

[0004] Due to the stress concentration, the steel beam or the anchorage itself is prone to deformation. After the deformation of the anchorage, the fit of the anchorage with the pipeline and the steel beam is reduced, which can cause the pipeline to move slightly or shake, and can easily cause problems such as bolt loosening and welding point cracking, so that the anchorage loses the effective support ability. Not only does it need to be frequently stopped for maintenance and replacement, which greatly increases the operation and maintenance cost, but also shortens the service life of the entire support system. SUMMARY

[0016] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1-4As shown, a prefabricated anchor fastening structure for heavy pipeline support in a steel structure factory includes a steel beam 1. A set of first anchors 2 are installed at each end of the steel beam 1. A second anchor 3 is installed on the steel beam 1 between the two sets of first anchors 2. A first locking screw 2-9 is screwed onto the first anchor 2, and a first locking plate 2-8 is rotatably connected to the top of the first locking screw 2-9. A second locking screw 3-4 is screwed onto the second anchor 3, and a second locking plate 3-3 is rotatably connected to the top of the second locking screw 3-4. A plug 2-2 is fixedly installed on the top of the side wall of each first anchor 2. A guide rod 2-1 is fixedly inserted between two opposite plugs 2-2. Each guide rod 2-1 passes through the second anchor 3 and is slidably connected to it. A first connecting anchor 2-3 is installed below each group of first anchors 2, and a second connecting anchor 3-1 is installed below each group of second anchors 3. Two steel wire ropes 2-17 are installed between the two first connecting anchors 2-3. The two steel wire ropes 2-17 are positioned below the second connecting anchors 3-1 and are kept taut. A lifting frame 4 is fixedly installed at the bottom of the second anchor 3, and a pipe clamp 5 is fixedly installed at the bottom of the lifting frame 4. A pipe is installed inside the pipe clamp 5. The first anchor is initially fixed to the steel beam by the first locking screw and the first locking plate.

[0018] like Figures 1-2As shown, the wire rope 2-17 is made of high-strength alloy material, and each wire rope 2-17 has a locking buckle installed at its end. The ends of two wire ropes 2-17 on the same side are respectively fixedly fitted with locking blocks 2-20. Two telescopic rods 2-19 are fixedly installed at the top of each locking block 2-20. Each telescopic rod 2-19 consists of a cylinder and a telescopic column. A moving block 2-18 is fixedly connected to the top of each telescopic rod 2-19. The moving block 2-18 is fitted onto the corresponding guide rod 2-1 and slidably connected to it. Two... Each spring cylinder 2-4 contains a first spring 2-6, and each spring cylinder 2-4 is slidably connected to a first T-shaped slide rod 2-5. The top of each first T-shaped slide rod 2-5 protrudes from and is slidably connected to the corresponding spring cylinder 2-4. A compression plate 2-7 is fixedly installed at the top of each first T-shaped slide rod 2-5, and the top of each compression plate 2-7 is fitted against the bottom of the corresponding first locking screw 2-9. A plug block 2-21 is fixedly installed on the side wall of the first anchor 2, and the bottom of each plug block 2-21 is inserted into the first connecting... The top of the anchor frame 2-3 is slidably connected to it. A connecting block 2-12 is fixedly installed at the bottom of each first anchor 2. Each connecting block 2-12 passes through the bottom of the first connecting anchor frame 2-3 and is slidably connected to it. A locking anchor rod 2-13 is inserted between corresponding two connecting blocks 2-12. Nuts are screwed to both ends of the locking anchor rod 2-13. A flared sleeve 2-10 is fixedly installed inside the first connecting anchor frame 2-3. A T-shaped rotating rod 2-11 is rotatably connected inside the flared sleeve 2-10. The bottom of the T-shaped rotating rod 2-11 is flared. It is rotatably connected to the inner wall of the trumpet-shaped sleeve 2-10, and multiple bolts are screwed to the top of the T-shaped rotating rod 2-11; the initial connection between the first anchor and the first connecting anchor is achieved through the insert block, connecting block and locking anchor rod; when the end of the wire rope breaks, the swaying range of the broken end of the wire rope is limited by the locking block, telescopic rod and moving block to prevent the broken end from scratching the pipeline; by rotating the T-shaped rotating rod, its top is changed from a vertical state to a horizontal state, which facilitates the first connecting anchor to be inserted through the gap between the two first anchor frames and fixed and limited, thereby improving the stability of the device.

[0019] like Figure 3 , 5As shown, the first connecting anchor 2-3 is U-shaped. A first adjusting screw 2-15 is screwed to the middle of the bottom of one of the first connecting anchors 2-3 along the direction of the crossbeam. One end of the first adjusting screw 2-15 is rotatably connected to a strip plate 2-16. One end of each of the two steel wire ropes 2-17 is fixedly connected to the side wall of the strip plate 2-16. Square guide blocks 2-14 are fixed to both ends of the side wall of the strip plate 2-16. Each square guide block 2-14 passes through the first connecting anchor 2-3 and is slidably connected to it. A U-shaped limiting clamp 2-24 is fitted in the middle of the strip plate 2-16. One side of the U-shaped limiting clamp 2-24 is rotatably connected to a second adjusting screw 2-23. The first connecting anchor 2-3... -3 The bottom end is fixedly connected to the U-shaped frame 2-22, and the strip plate 2-16 is set inside the U-shaped frame 2-22. The second adjusting screw 2-23 passes through the U-shaped frame 2-22 and is threadedly connected to it. The bottom end of the other first connecting anchor 2-3 is fixedly connected to the mounting frame 2-26. The mounting frame 2-26 is U-shaped, and the mounting block 2-25 is inserted into the mounting frame 2-26. The other ends of the two steel wire ropes 2-17 are fixedly connected to the side wall of the mounting block 2-25 respectively. The mounting frame 2-26 is screwed with bolts. The connecting plate is clamped by the U-shaped limiting clamp to prevent the connecting plate from moving back, maintain the prestress of the steel wire rope, distribute the force and avoid local deformation. The double screw limiting fixation ensures its stability.

[0020] like Figure 4 , 5As shown, L-shaped fixing plates 3-2 are fixedly connected to the side walls and bottom of the second anchor 3. The second connecting anchor 3-1 is made of steel and is fitted over the two second anchors 3 and slidably connected to them. Multiple bolts are screwed to the bottom of the second connecting anchor 3-1. Each L-shaped fixing plate 3-2 is inserted into the corresponding slot of the second connecting anchor 3-1. The bottom ends of the second connecting anchor 3-1 are slidably connected to the second T-shaped sliding rods 3-6. Each second T-shaped sliding rod 3-6 is fitted with a second spring 3-9. The bottom ends of the two second T-shaped sliding rods 3-6 are fixedly connected to the moving plate 3-7. Two guide cylinders 3-8 are fixedly installed at the bottom of the moving plate 3-7. The opening of the guide cylinder 3-8 is provided with a chamfer. Two steel wire ropes 2-17 pass through the corresponding guide cylinders 3-8 and are slidably connected to them. Lubricant is applied to the inner wall of the guide cylinder 3-8. An I-shaped top plate 3 is fixedly connected to the two second T-shaped sliding rods 3-6. -5. The top of the I-shaped top plate 3-5 is fitted to the bottom of the steel beam 1. Friction pads are fixedly installed on the tops of the two second T-shaped slide rods 3-6 respectively. The tops of the friction pads are fitted to the bottoms of the corresponding second locking screws 3-4. A pressure sensor 3-10 is fixedly installed on the top of the I-shaped top plate 3-5. The pressure sensor 3-10 outputs pressure values ​​in real time, and the operator can judge the tension of the wire rope 2-17 by the pressure value. The second anchor is initially fixed by the L-shaped fixing plate, the second locking screw, and the second locking plate. The friction pads are fitted to the bottoms of the second locking screws to enhance the anti-slip effect of the second locking screws. The prestress state of the wire rope is monitored by the real-time data of the pressure sensor. If the pressure value is lower than the preset threshold, the first adjusting screw is readjusted to tighten the wire rope. If the pressure value rises abnormally, safety hazards are investigated in time. The pressure sensor transmits wireless signals to the signal transmitter for easy monitoring by the operator.

[0021] The fastening method based on the above fastening structure involves the following specific steps: S1: Place the two sets of first anchors 2 in the preset area below the steel beam 1 respectively. Insert the guide rod 2-1 into the two opposite inserts 2-2. According to the pipeline installation requirements of the plant area, put the corresponding number of second anchors 3 on the guide rod 2-1. Rotate the first locking screw 2-9. The first locking plate 2-8 presses against the bottom of the steel beam 1 to complete the initial fixation of the first anchor 2. Move the first connecting anchor 2-3 close to the first anchor 2 from below. Insert the insert block 2-21 on the side wall of the first anchor 2 into the slot at the top of the first connecting anchor 2-3. At the same time, the connecting block 2-12 at the bottom of the first anchor 2 passes through the through hole at the bottom of the first connecting anchor 2-3. Insert the locking anchor rod 2-13 into the through hole of the two opposite connecting blocks 2-12. Thread nuts to both ends of the locking anchor rod 2-13. Tighten the nuts to complete the initial connection between the first anchor 2 and the first connecting anchor 2-3. S2: The two locking blocks 2-20 on the wire rope 2-17 are connected to the moving block 2-18 on the guide rod 2-1 through the telescopic rod 2-19. If the end of the wire rope 2-17 breaks, the locking block 2-20, through the constraint of the telescopic rod 2-19 and the moving block 2-18, limits the swing range of the broken end of the wire rope 2-17 and prevents the broken end from colliding with the pipeline. The telescopic rod 2-19 and the moving block 2-18 ensure that the wire rope 2-17 remains taut during installation. S3: When the first spring 2-6 inside the spring cylinder 2-4 is in a compressed state, it pushes the first T-shaped slide bar 2-5 and the extrusion plate 2-7 to press against the bottom end of the first locking screw 2-9, thereby enhancing the anti-slip effect of the first locking screw 2-9. S4: Rotate the T-shaped rotating rod 2-11 on the first connecting anchor 2-3, so that its top changes from a vertical position to a horizontal position, making it easier for the first connecting anchor 2-3 to pass through the gap between the two first anchor frames 2 and to fix and limit its position. Then, screw bolts into the bolt holes at the top of the T-shaped rotating rod 2-11 and tighten them. The T-shaped rotating rod 2-11 restricts the vertical displacement of the first anchor 2, further ensuring the stability of the connection. S4: Fix one end of each of the two high-strength alloy steel wire ropes 2-17 to the connecting ring on the side wall of the strip plate 2-16 via a lock, and connect the other end to the side wall of the mounting block 2-25 inside the mounting bracket 2-26 at the bottom of the first connecting anchor 2-3 via a lock. Tighten the bolts on the mounting bracket 2-26 to fix the mounting block 2-25. Then rotate the first adjusting screw 2-15 to push the strip plate 2-16 to move along the direction of the square guide block 2-14, stretching the steel wire rope 2-17 to a taut state. Then rotate the second adjusting screw 2-23 to clamp the strip plate 2-16 through the U-shaped limiting clamp 2-24 to prevent the strip plate 2-16 from shifting back and to maintain the prestress of the steel wire rope 2-17. The double screw limiting fixation ensures its stability. S5: Rotate the second locking screw 3-4 on the second anchor 3, and the second locking plate 3-3 presses against the bottom of the steel beam 1 to complete the initial fixing of the second anchor 3. At this time, the friction pad 3-11 at the top of the second T-shaped slide bar 3-6 is in contact with the bottom of the second locking screw 3-4 to enhance the anti-slip effect of the second locking screw 3-4. The second connecting anchor 3-1 made of steel is placed on the outside of the two second anchors 3 from the side. The L-shaped fixing plate 3-2 on the side wall and bottom of the second anchor 3 is inserted into the corresponding slot of the second connecting anchor 3-1. Tighten the bolt at the bottom of the second connecting anchor 3-1 to fix the second connecting anchor 3-1 and the second anchor 3. S6: During installation, two steel wire ropes 2-17 pass through guide cylinders 3-8 on the moving plate 3-7 below the second connecting anchor 3-1. The number of second connecting anchors 3-1 is set according to the number of second anchors 3 above. The bevel angle at the end of the guide cylinder 3-8 facilitates the insertion of the steel wire ropes 2-17. The lubricant on the inner wall reduces friction when the steel wire ropes 2-17 slide. When the steel wire ropes 2-17 are taut, they push the moving plate 3-7 upward, causing the second T-shaped slide bar 3-6 and the I-shaped top plate 3-5 to rise, so that the pressure sensor 3-10 at the top of the I-shaped top plate 3-5 is in contact with the bottom of the steel beam 1, and the pressure sensor... The pressure sensor 3-10 outputs a pressure value in real time, allowing operators to determine the tension of the wire rope 2-17. During daily use, the prestress of the wire rope 2-17 is monitored through the real-time data from the pressure sensor 3-10. If the pressure value is lower than the preset threshold, it indicates that the wire rope 2-17 is loose. The first adjusting screw 2-15 is then readjusted to tighten the wire rope 2-17. If the pressure value rises abnormally, the pipeline load is checked for overload, and potential safety hazards are promptly identified and addressed. The pressure sensor 3-10 transmits a wireless signal to the signal transmitter, which then transmits the signal to the central control room for easy monitoring by operators.

[0022] The fastening process of this fastening structure adopts an installation-then-positioning procedure, which eliminates the need for precise positioning and measurement in the early stage, followed by the installation of anchors. This simplifies the operation steps and improves the installation efficiency of heavy pipeline support structures.

8. A fastening method based on the fastening structure described in claims 1-7, characterized in that, The specific steps are as follows: S1: Place the two sets of first anchors (2) in the preset area below the steel beam (1), insert guide rods (2-1) into the two opposite inserts (2-2), and according to the pipeline installation requirements of the plant area, fit the corresponding number of second anchors (3) onto the guide rods (2-1), rotate the first locking screw (2-9), and the first locking plate (2-8) presses against the bottom of the steel beam (1) to complete the initial fixing of the first anchors (2). Then, move the first connecting anchor (2-3) from below close to the first anchors (2-2). 2) The insert block (2-21) on the side wall of the first anchor (2) is inserted into the slot at the top of the first connecting anchor (2-3). At the same time, the connecting block (2-12) at the bottom of the first anchor (2) passes through the through hole at the bottom of the first connecting anchor (2-3). The locking anchor rod (2-13) is inserted into the through hole of the two connecting blocks (2-12) and nuts are screwed onto both ends of the locking anchor rod (2-13). Tightening the nuts completes the initial connection between the first anchor (2) and the first connecting anchor (2-3). S2: The two locking blocks (2-20) on the wire rope (2-17) are connected to the moving block (2-18) on the guide rod (2-1) through the telescopic rod (2-19). If the end of the wire rope (2-17) breaks, the locking block (2-20) limits the swing range of the broken end of the wire rope (2-17) through the constraint of the telescopic rod (2-19) and the moving block (2-18), so as to avoid the broken end from colliding with the pipeline. The telescopic rod (2-19) and the moving block (2-18) ensure that the wire rope (2-17) remains taut during the installation process. S3: When the first spring (2-6) inside the spring cylinder (2-4) is in a compressed state, it pushes the first T-shaped slide bar (2-5) and the extrusion plate (2-7) to press against the bottom end of the first locking screw (2-9), thereby enhancing the anti-slip effect of the first locking screw (2-9); S4: Rotate the T-shaped rotating rod (2-11) on the first connecting anchor (2-3) so that its top changes from vertical to horizontal, making it easier for the first connecting anchor (2-3) to pass through the gap between the two first anchor frames (2) and to fix and limit its position. Then, screw the bolt into the bolt hole at the top of the T-shaped rotating rod (2-11) and tighten it. The T-shaped rotating rod (2-11) restricts the vertical displacement of the first anchor (2) and further ensures the connection stability. S4: Fix one end of each of the two high-strength alloy steel wire ropes (2-17) to the connecting ring on the side wall of the strip plate (2-16) through a lock buckle, and connect the other end to the side wall of the mounting block (2-25) in the bottom mounting bracket (2-26) of another first connecting anchor (2-3) through a lock buckle. Tighten the bolts on the mounting bracket (2-26) to fix the mounting block (2-25). Then rotate the first adjusting screw (2-15) to push the strip plate (2-16) to move along the direction of the square guide block (2-14) and stretch the steel wire rope (2-17) to a taut state. Then rotate the second adjusting screw (2-23) to clamp the strip plate (2-16) through the U-shaped limiting clamp (2-24) to prevent the strip plate (2-16) from moving back and to maintain the prestress of the steel wire rope (2-17). The double screw limiting fixation ensures its stability. S5: Rotate the second locking screw (3-4) on the second anchor (3), and the second locking plate (3-3) presses against the bottom of the steel beam (1) to complete the initial fixing of the second anchor (3). At this time, the friction pad (3-11) at the top of the second T-shaped slide rod (3-6) is in contact with the bottom of the second locking screw (3-4) to enhance the anti-slip effect of the second locking screw (3-4). The second connecting anchor (3-1) made of steel is placed on the outside of the two second anchors (3) from the side. The L-shaped fixing plate (3-2) on the side wall and bottom of the second anchor (3) is inserted into the corresponding slot of the second connecting anchor (3-1). Tighten the bolt at the bottom of the second connecting anchor (3-1) to fix the second connecting anchor (3-1) and the second anchor (3). S6: During installation, two steel wire ropes (2-17) pass through the guide tubes (3-8) on the moving plate (3-7) below the second connecting anchor (3-1); the number of the second connecting anchors (3-1) is set according to the number of the second anchors (3) above. The guide angle at the port of the guide tube (3-8) facilitates the insertion of the steel wire rope (2-17). The lubricant on the inner wall reduces the friction when the steel wire rope (2-17) slides. When the steel wire rope (2-17) is taut, it pushes the moving plate (3-7) upward, driving the second T-shaped slide bar (3-6) and the I-shaped top plate (3-5) to rise, so that the pressure sensor (3-10) at the top of the I-shaped top plate (3-5) is aligned with the bottom of the steel beam (1). The pressure sensor (3-10) outputs a pressure value in real time, allowing operators to determine the tension of the wire rope (2-17). During daily use, the prestress of the wire rope (2-17) is monitored through the real-time data from the pressure sensor (3-10). If the pressure value is lower than the preset threshold, it indicates that the wire rope (2-17) is loose. The first adjusting screw (2-15) is then readjusted to tighten the wire rope (2-17). If the pressure value rises abnormally, the pipeline load is checked for overload, and potential safety hazards are promptly identified. The pressure sensor (3-10) transmits a wireless signal to the signal transmitter, which then transmits the signal to the central control room for easy monitoring by operators.
