Description

Technical Field

[0001] This application relates to the technical field of steel structure building reinforcement, and in particular to a steel structure building reinforcement structure and reinforcement method. Background Technology

[0002] Steel structures are structures primarily made of steel and are a common structural form in modern construction engineering. Steel has the characteristics of high strength, light weight, good overall rigidity, and strong deformation capacity. It is usually used to construct large-span, super-high, and super-heavy buildings. Some steel structure connection nodes are generally welded. After long-term use, under stress, the stability and strength of these connection nodes will weaken. Therefore, reinforcement structures are used to strengthen the connection nodes to ensure the overall stability of the steel structure.

[0003] Existing Chinese patent CN220790709U discloses a reinforcement structure for beams in steel structures, comprising an L-shaped steel plate, a load-bearing column, and a load-bearing beam. The L-shaped steel plate is fixedly installed on the load-bearing column by fixing bolts. The end of the L-shaped steel plate away from the load-bearing column is fixedly installed on the bottom of the load-bearing beam by fixing bolts. A first mounting plate is fixedly installed at the end of the L-shaped steel plate located on the load-bearing column, and a diagonal brace is fixedly installed on the first mounting plate. By installing an L-shaped steel frame between the load-bearing beam and the load-bearing column, and fixing the L-shaped steel frame to the load-bearing beam and the load-bearing column at the bend of the L-shaped steel frame, the load-bearing column can effectively share part of the load-bearing pressure of the load-bearing beam, and the load-bearing column makes the L-shaped steel plate a stable triangle.

[0004] In the aforementioned technologies, diagonal bracing columns can effectively distribute some of the load-bearing pressure from the load-bearing beams. However, their installation relies on welding or clamps, posing a high risk of component slippage and potential safety accidents. Furthermore, installation requires multiple adjustments and temporary fixation, making the installation of a single diagonal bracing column time-consuming, challenging high-altitude operations, and incompatible with bracing installations at different angles. This results in poor versatility, as the fit of the contact surfaces depends on worker experience, and bolt hole misalignment necessitates enlarging, weakening the joint strength. Moreover, it is impossible to monitor the diagonal bracing column for deformation in real time after reinforcement. Therefore, there is room for improvement beyond the existing technology.

The threaded head of the pin head is threadedly connected to the connecting cap. The snap-fit ​​component, which is squeezed by the pin head, is inserted into the horizontal groove.

[0030] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0031] This application discloses a steel structure building reinforcement structure. The application first clamps and positions the H-shaped steel beam with the clamping member 1. The reinforcement rod 4 is rotated with the clamping member 1 as the rotation base point, so that the positioning member 5 connected to the upper end of the reinforcement rod 4 gradually fits into the H-shaped beam until it is completely fitted. The H-shaped beam is marked with color by the marking member 6. Then the reinforcement rod 4 and the positioning member 5 are rotated and removed, and holes are drilled in the marking. Subsequently, the predetermined holes are locked to the positioning member 5 with bolts. The whole process does not require multiple adjustments, and the overall structure maintains the original rigid support.

[0032] Reference Figures 1-8 As shown, this embodiment discloses a steel structure building reinforcement structure, including a clamping component 1, a connecting component 2, a rotating component 3, a reinforcing rod 4, a positioning component 5, a marking component 6, and a support warning component 7. The clamping component 1 has connecting components 2 symmetrically installed at its left and right ends, and the clamping component 1 provides a thickened positioning connection for the H-shaped steel beam. The rotating component 3 is internally rotatably connected to the connecting component 2. The reinforcing rod 4 is connected between the rotating component 3 and the positioning component 5. The positioning component 5 has a detachable marking component 6 around its periphery, which marks the H-shaped beam. The support warning component 7 is installed at the lower end of the reinforcing rod 4. When deformation occurs during the steel structure support process, the structure of the support warning component 7 changes, thereby providing a warning.

[0033] In the actual reinforcement process, after determining the height of the clamping part 1 at the H-shaped steel beam, holes are drilled. Then, the clamping part 1 is fixed at the designated height of the H-shaped steel beam. The rotating part 3 is inserted laterally into the connecting part 2. Using the rotating part 3 as a reference, the reinforcement rod 4 is rotated until the positioning part 5 is tightly attached to the lower end face of the H-shaped crossbeam. At this time, the marking part 6 is squeezed and marks the lower end face of the H-shaped crossbeam with color. After the marking operation, the reinforcement rod 4 is rotated away and the marking part 6 is removed from the positioning part 5. Holes are drilled at the marked positions. After the drilling is completed, the reinforcement rod 4 is rotated again until the positioning part 5 moves back to the marked position. At this time, the positioning part 5 is locked to the hole position by bolts. At this time, the positions of both ends of the reinforcement rod 4 are locked. The building is reinforced by the reinforcement rod 4. During the reinforcement process, the support warning part 7 is used to further support and reinforce the reinforcement rod 4 and to provide timely warnings in case of collapse.

[0034] Reference Figure 2 As shown, the clamping member 1 includes a thickened plate 11, which is respectively attached to the left and right positions of the H-shaped steel beam. The thickened plate 11 and the H-shaped steel beam are locked in position by the lateral insertion of the threaded member 12.

[0035] Reference Figure 2 As shown, the threaded component 12 consists of a threaded post and a nut. The threaded post is inserted laterally into the thickened plate 11 on the right side, the H-shaped steel beam, and the thickened plate 11 on the left side. The threaded structure of the threaded post is threadedly connected to the nut.

[0036] In the actual installation process, after determining the height of the clamping part 1 on the H-shaped steel beam, it is marked and drilled. Then, the thickened plate 11 is attached to the left and right positions of the H-shaped steel beam respectively, and the position of the thickened plate 11 and the H-shaped steel beam is locked by the transverse insertion of the threaded part 12.

[0037] Reference Figure 9 As shown, the connector 2 has a slot in the middle and a snap-fit ​​groove 21 at the lower end of the slot.

[0038] Reference Figure 2 , Figure 9 As shown, the rotating component 3 includes a connector 31, which is inserted laterally into the slot. The interior of the connector 31 is connected to the connecting rod 32 via a pin. The lower end of the connector 31 has an internal groove corresponding to the position of the snap-fit ​​groove 21. A snap-fit ​​block 33 is slidably disposed in the internal groove. The lower inner side of the snap-fit ​​block 33 has a chamfered structure. The middle part of the connecting rod 32 has a sliding groove. A top support rod 34 is slidably disposed in the sliding groove. The length of the top support rod 34 is greater than the length of the connecting rod 32.

[0039] In the actual connection process, the connector 31 is inserted horizontally into the slot. After insertion, the locking block 33 falls into the locking groove 21 under the action of gravity to perform pre-locking (longitudinal locking). The connector 31 and the connector 2 are locked in position by the dual methods of horizontal and longitudinal insertion. At this time, one end of the reinforcing rod 4 is connected. Subsequently, the reinforcing rod 4 can be rotated by the rotational connection between the connector 31 and the connecting rod 32.

[0040] Reference Figures 1-2 As shown, the reinforcing rod 4 includes a support rod 41. The inner end of the support rod 41 is provided with a movable groove 42. The movable groove 42 and the connecting rod 32 are slidably connected. A reinforcing rib 43 is built into the middle of the support rod 41. A thickened rod 44 is installed at the upper end of the support rod 41. The outer end of the support rod 41 is locked to the concave head of the connecting block 45 by a pin 46. The end face of the outer end of the support rod 41 is a beveled structure. The beveled structure makes it easier to remove the support rod 41 after it is separated from the connecting block 45. The beveled structure gradually slopes outward from top to bottom. A connector 47 is installed at the outer end of the connecting block 45.

[0041] Reference Figures 4-5 , Figure 10 As shown, the pin 46 includes a snap-fit ​​member 461, which is horizontally slidably disposed in the horizontal groove 4611 of the connecting block 45. The snap-fit ​​member 461 and the horizontal groove 4611 are elastically connected. The position between the outer end snap-fit ​​member of the support rod 41 and the concave head of the connecting block 45 is locked by the lateral insertion of the pin head 462. The threaded head of the pin head 462 is threadedly connected to the connecting cap. The snap-fit ​​member 463, which is pressed by the pin head 462, is inserted into the horizontal groove 4611 and slides horizontally. The working groove is set in the support rod 41. When the new support rod 41 and the connecting block 45 are reassembled, the specific steps are as follows: rotate the support rod 41 until its outer end snap-fit ​​connector is re-engaged with the concave head of the connecting block 45. Then insert the pin head 462 laterally. Under the pressure of the inserted pin head 462, the snap-fit ​​part 463 is re-inserted into the horizontal groove 4611. Finally, re-thread the connecting cap and the threaded head of the pin head 462. At this time, the support rod 41 and the connecting block 45 are locked again.

[0042] During actual rotation, rotating the support rod 41 causes the positioning part 5 to gradually approach the H-shaped crossbeam. After they contact each other, rotation continues until the positioning part 5 is completely fitted against the lower end face of the H-shaped crossbeam (at this point, the positioning part 5 reaches the installation position). During this process, the relative positions of the support rod 41 and the connecting rod 32 are displaced, causing the outer half of the connecting rod 32 to further retract into the movable groove 42. At this time, the outer end of the top support rod 34 is squeezed by the movable groove 42, causing it to displace relative to the connecting rod 32, so that the inner end of the top support rod 34 extends out and abuts against the upper end of the locking block 33. This allows the snap-fit ​​block 33 and the snap-fit ​​groove 21 to form a final longitudinal snap-fit ​​lock. When the support rod 41 needs to be replaced after the reinforcement is completed (at this time, the support rod 41, as the main support structure, is more likely to bend under pressure, and needs to be replaced if the support rod 41 bends), simply separate the connecting cap from the threaded head of the pin head 462 and pull the pin head 462 out laterally. At this time, the snap-fit ​​part 461 will push the snap-fit ​​part 463 out of the horizontal groove 4611 under the elastic action. At this time, the support rod 41 is separated from the connecting block 45, and the support rod 41 can be easily rotated and removed.

[0043] Reference Figure 3 , Figure 10 As shown, the positioning component 5 includes a connecting plate 51, with a bracket installed on the inner side of the connecting plate 51. The brackets are connected to the rotating shaft 52 via bearings, and the two are rotatably connected to ensure that the positioning component 5 can always be parallel and in contact with the H-shaped crossbeam during the rotation of the support rod 41. The rotating shaft 52 is fixedly connected to the connector 47. A resistance-increasing component 53 is slidably arranged in the middle of the connecting plate 51. A resistance-increasing layer with a concave arc structure is opened on the inner side of the resistance-increasing component 53. After the resistance-increasing layer contacts the arc surface of the connector 47, a resistance-increasing contact is formed. The connecting plate 51 and the bonding frame 54 are slidably connected. A circular hole 55 is opened around the periphery of the bonding frame 54.

[0044] Reference Figure 3As shown, the marking element 6 includes a contact head 61, which is threadedly connected to a threaded hole in the connecting plate 51. The threaded hole corresponds to the position of the circular hole 55. The contact head 61 is connected to the liquid storage frame 62. A piston plate 63 is provided inside the liquid storage frame 62. A spring telescopic element is connected between the piston plate 63 and the liquid storage frame 62. A spray hole is provided at the end of the contact head 61 away from the liquid storage frame 62. The diameter of the spray hole is smaller than the diameter of the inner cavity of the contact head 61, ensuring that the spray hole will not be sprayed when the partition ball 631 moves into the inner cavity. The hole is blocked, and a temporary blockage ball 631 is placed in the ejection hole. A contact 64 is coaxially installed on the outer end of the blockage ball 631. The inner end of the blockage ball 631 is connected to the inner cavity of the contact head 61 through a spring return piece 65. After color marking, the contact head 61 is removed from the threaded hole so that the marking piece 6 is completely removed. Then, holes are drilled at the marked positions. When the positioning piece 5 is connected to the hole, the bolt is passed through the threaded hole, the round hole 55, and the hole in sequence and locked to the cap head. At this time, the positioning piece 5 is locked in position with the H-shaped crossbeam.

[0045] During the actual marking process, the support rod 41 is rotated upward to make the positioning part 5 contact the lower end face of the H-shaped crossbeam. As the rotation angle of the support rod 41 gradually increases, the distance between the bonding frame 54 and the connecting plate 51 gradually decreases. When the positioning part 5 reaches the installation position, the bonding frame 54 and the connecting plate 51 are in contact. The friction-increasing part 53 is squeezed by the bonding frame 54 and makes friction-increasing contact with the arc-shaped surface of the connector 47. The contact part 64 in the contact head 61 is squeezed and completely retracts into the spray hole. The synchronously moving partition ball 631 no longer blocks the spray hole. The marking liquid in the liquid storage frame 62 is sprayed out from the spray hole under the pressure of the elastically connected piston plate 63, thereby marking the color. At the same time, the reinforcing rod 4 is also in the support position.

[0046] Reference Figure 2 , Figure 11 As shown, the supporting warning component 7 includes a warning rod 71. One end of the warning rod 71 is connected to the lower end of the supporting rod 41 via a pin. The other end of the warning rod 71 is equipped with an L-shaped snap hook 72. The L-shaped component 73, which snaps into the snap hook 72, is slidably disposed in the longitudinal rod 74. The upper end of the longitudinal rod 74 is installed in a hidden groove, which is opened in a traction block 75. The traction block 75 is horizontally slidably disposed in a storage groove opened in a connecting seat 76. The connecting seat 76 is installed on the lower end face of the supporting rod 41. A pressing block 77 is installed at the bottom of the storage groove. The upper end of the pressing component 78, which is pressed against the inclined surface of the pressing block 77, is installed at the lower end of the L-shaped component 73.

[0047] In actual operation, after the positions of both ends of the reinforcing rod 4 are determined and installed, the building is reinforced by the reinforcing rod 4. During the reinforcement, the warning rod 71 assists the reinforcing rod 4 in reinforcement support. When the steel structure building collapses and the support rod 41 deforms and bends, the concave bending of the support rod 41 causes the warning rod 71, which is rotatably connected to one end of the support rod 41 (at this time, the warning rod 71 will also deform), to drive the L-shaped part 73 to move in a traction displacement. Under the pressure of the inclined surface of the pressing block 77, the L-shaped part 73 is pulled and moves towards the position of the longitudinal rod 74, so that the locking hook 72 and the L-shaped part 73 gradually separate until they are completely separated. At this time, one end of the warning rod 71 is unlocked, causing the warning rod 71 to rotate downward until it forms a suspended state. The workers below can judge whether the reinforcing rod 4 has deformed by checking whether the warning rod 71 is in a suspended state. When the warning rod 71 is in a suspended state, it needs to be checked in time. The surface of the warning rod 71 is coated with a warning reflective color.

[0048] This application also discloses a method for reinforcing steel structure buildings, specifically including the following steps: S1. Connect the clamping component 1 to the H-beam for height positioning; S2. Make an embedded rotating connection between the rotating part 3 and the connecting part 2; S3. Using the rotating part 3 as a reference, rotate the reinforcing rod 4 until the positioning part 5 is tightly attached to the lower end face of the H-shaped beam. After determining the hole position, mark the lower end face of the H-shaped beam with color using the marking part 6. S4. Drill holes at the marked positions and lock the positioning part 5 to the holes using bolts. S5. The building is reinforced by the reinforcing rod 4. During the reinforcement process, the reinforcing rod 4 is further supported and reinforced by the supporting warning piece 7. When the reinforcing rod 4 bends, the structure in the reinforcing rod 4 changes, thus providing a warning.

[0049] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
