Description

Technical Field

[0001] This application relates to the field of space frame components technology, and in particular to a steel space frame reinforcement device. Background Technology

[0002] Space frame structures are spatial structures composed of multiple members connected at nodes in a specific grid pattern. They offer advantages such as low spatial stress, light weight, high stiffness, and good seismic performance. However, in large-span space frame structures, with increasing service life, some members may experience bending deformation under complex environmental conditions such as roof loads, wind and snow loads, and dust accumulation loads. This is highly detrimental to the normal use of the structure and necessitates reinforcement of these members.

[0003] A search revealed that Chinese patent CN219569680U discloses a reinforcement device for steel space frame members. This device effectively connects a first steel arc plate and a second steel arc plate using multiple fixing bolts, thereby pressing carbon fiber cloth onto the surface of the space frame member. One or more layers of carbon fiber cloth can alleviate the radial pressure on the surface of the space frame member, thus preventing deformation. However, this device uses bolts to fix the first and second steel arc plates, and after prolonged use, the bolts are prone to loosening, affecting the reinforcement effect. Therefore, a steel space frame member reinforcement device is proposed to solve the above problems. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-6 This utility model provides a steel space frame member reinforcement device for reinforcing steel space frame members, which has the function of ensuring reinforcement effect. Technical solution:

[0026] A steel space frame member reinforcement device includes a first steel arc plate 1 and a second steel arc plate 2. The first steel arc plate 1 and the second steel arc plate 2 are connected and fixed by bolts 3 and wrap around the member 4. A stop member 5 is provided on the side of the first steel arc plate 1. The stop member 5 has a stop surface 51, which is in contact with the nut of the bolt 3.

[0027] Specifically, by setting the stop plate 53 of the stop member 5 to fit with the nut of the bolt 3, the bolt 3 is prevented from retracting along its axis, thus avoiding the bolt 3 from becoming loose. This ensures the reinforcement effect of the first steel arc plate 1 and the second steel arc plate 2, thereby enabling the steel grid member 4 reinforcement device to have the function of ensuring the reinforcement effect.

[0028] The first steel arc plate 1 is fixedly connected to the front and rear sides with a first extension ear 11. A first through hole is opened on the side of the first extension ear 11. The second steel arc plate 2 is fixedly connected to the front and rear sides with a second extension ear 21. A welding seat 22 is fixedly connected to the side of the second extension ear 21 away from the first extension ear 11. A second through hole is opened on the side of the second extension ear 21, penetrating the welding seat 22. A nut 6 is welded inside the welding seat 22. The first through hole, the second through hole, and the nut 6 have the same axis. A bolt 3 is set on the inner wall of the first through hole and the second through hole and is threadedly connected to the nut 6. By setting the welding seat 22 to fix the nut 6, the user is prevented from holding the nut 6 during installation, thus improving the portability during installation.

[0029] A limiting rod 7 extending along its length is fixedly connected to the outer side of the first extension ear 11. A stop 5 is sleeved on the outside of the limiting rod 7. A limiting block 71 is fixedly connected to the bottom end of the limiting rod 7. By setting the limiting rod 7, it is convenient to install and remove the stop 5. When tightening or loosening most of the bolts 3, the stop 5 can be removed for easy operation. The cross section of the limiting rod 7 is T-shaped or dovetail-shaped.

[0030] The stop member 5 includes a connecting plate 52 and a stop plate 53 fixedly connected to the end of the connecting plate 52. The stop member 5 has an L-shaped cross section, and the stop surface 51 is formed on the inner side of the stop plate 53. The top of the connecting plate 52 is provided with a limiting groove 54 that extends through the bottom end. The limiting groove 54 is adapted to the limiting rod 7. By setting the stop member 5 in an L-shape, it is ensured that the user can tighten or loosen the bolt 3 without removing the stop member 5, avoiding the need to remove the stop member 5 when operating on a single bolt 3, and improving the portability of operation.

[0031] The stop member 5 also includes a locking part 55. The top end of the first extension ear 11 is provided with a travel groove 12, and the bottom of the travel groove 12 is provided with a locking groove 13. When the locking part 55 moves along the travel groove 12 to the locking groove 13, it locks the stop member 5.

[0032] The locking part 55 includes a fixing block 551 fixedly connected to the stop surface 51. The front of the fixing block 551 is provided with a sliding groove 552. Two locking blocks 553 are slidably connected in the sliding groove 552. The opposite surfaces of the two locking blocks 553 are fixedly connected to the same spring 554. The bottom of the locking block 553 is provided with a chamfer 555. By setting the locking groove 13, with the cooperation of the limiting block 71, the stop 5 is prevented from displacing in the height direction, thus improving stability.

[0033] Carbon fiber cloth 8 is adhered to the surface of the rod 4. The first steel arc plate 1 and the second steel arc plate 2 are set on the outside of the carbon fiber cloth 8. There are multiple carbon fiber cloths 8, and the multiple carbon fiber cloths 8 are bonded together with epoxy resin. The carbon fiber cloth 8 and the space frame rod are bonded together with epoxy resin.

[0034] Working principle: When using this steel grid member reinforcement device, the user first attaches carbon fiber cloth 8 to the surface of member 4, then puts the first steel arc plate 1 and the second steel arc plate 2 on the outer surface of member 4 to clamp member 4 and carbon fiber cloth 8. Then, the first steel arc plate 1 and the second steel arc plate 2 are fixed by bolts 3 and nuts 6. Then, the limiting groove 54 is aligned with the limiting rod 7, and the stop 5 is put on the outside of the limiting rod 7 so that the stop surface 51 fits with the nut of the bolt 3. During this process, the two limiting blocks 71 compress the spring 554 and move closer to each other under the cooperation of the chamfer 555 at the bottom and the travel groove 12, so that the locking part 55 can smoothly enter the locking groove 13. When it reaches the locking groove 13, the spring 554 returns to its original position, so that the two locking blocks 553 pop out and cooperate with the inner top wall of the locking groove 13 to prevent the stop 5 from moving upward, so that the steel grid member reinforcement device has the function of ensuring the reinforcement effect.
