Description

Technical Field

[0001] This utility model relates to the field of building construction safety technology, specifically, it is a steel grid frame pole reinforcement device. Background Technology

[0002] Steel space frame structures, especially spatial grid structures, are widely used in large-scale building construction due to their advantages such as rational stress distribution, large span, and light weight. These structures typically consist of a large number of standardized members connected at nodes to form a spatial load-bearing system. However, during long-term use, due to environmental corrosion, material aging, unexpected loads (such as earthquakes, strong winds, and snowstorms), or changes in usage (such as increased equipment loads), some members may experience insufficient load-bearing capacity, deformation, corrosion, or even breakage, posing a serious threat to the safety of the entire structure.

[0003] In the reinforcement of structural members of a building's space frame, external tubing welding fixtures are generally used. However, during the rainy season, welding work is carried out outdoors, which greatly reduces the quality of the welds and makes it difficult to guarantee safety. Utility Model Content

[0004] The purpose of this utility model is to provide a steel grid pole reinforcement device to avoid the use of welding process, improve reinforcement quality, reduce safety risks, and significantly shorten the reinforcement period.

[0005] To achieve the above objectives, the present invention employs the following technical means: A steel space frame pole reinforcement device includes: An external tube is coaxially fitted to the outer wall of the main rod, including a first U-shaped tube and a second U-shaped tube coaxially arranged with the main rod, and the inner walls of the first U-shaped tube and the second U-shaped tube are covered with rubber pads; A clamping mechanism is provided on the outer wall of the outer sleeve tube, which is used to attach the inner arc wall of the first U-shaped tube and the inner arc wall of the second U-shaped tube to the outer wall of the main rod respectively, and keep the first U-shaped tube and the second U-shaped tube in mutual contact and positioning. The clamping gap of the clamping mechanism is staggered with the splicing gap of the first U-tube and the second U-tube.

[0006] Preferably, the inner diameters of the first U-shaped tube and the second U-shaped tube are the same as the outer diameter of the main rod, and the inner arc sides of the first U-shaped tube and the second U-shaped tube are spliced ​​together to form a complete cylindrical channel for clamping the main rod.

[0007] Furthermore, the clamping mechanism includes a third U-shaped tube and a fourth U-shaped tube, the inner diameter of which is the same as the outer diameter of the first U-shaped tube and the second U-shaped tube. Each end of the third U-shaped tube and the fourth U-shaped tube is equipped with a fastening plate, and the fastening plates at both ends of the third U-shaped tube are connected to the fastening plates on both sides of the fourth U-shaped tube by bolts.

[0008] Furthermore, a washer is provided between the nut of the bolt and the fastening plate.

[0009] Furthermore, a reinforcing rib is installed between the third U-shaped tube and the fastening plate.

[0010] Furthermore, a reinforcing rib is installed between the fourth U-shaped tube and the fastening plate.

[0011] Furthermore, the outer wall of the outer casing is provided with a plurality of clamping mechanisms along its axial extension direction.

[0012] This utility model has the following beneficial effects during use: When reinforcing the steel grid frame poles, the first and second U-shaped tubes are directly clamped to the outer wall of the main pole, with their ends abutting against each other. Simultaneously, the rubber pads covering the inner walls of the first and second U-shaped tubes are fully fitted to the main pole. The clamping mechanism, in conjunction with the clamping mechanism, positions the first and second U-shaped tubes, ensuring a tight fit against the outer wall of the main pole. Furthermore, the clamping gap of the clamping mechanism is staggered with the splicing gap between the first and second U-shaped tubes. This allows for reinforcement of the main pole even without welding, giving the main pole better bending resistance. This improves reinforcement quality, reduces safety risks, and significantly shortens the reinforcement period. Moreover, thanks to the rubber pads, even if the clamping mechanism only applies radial force to the outer sheath, the outer sheath maintains good axial stability. Attached Figure Description

[0024] Please refer to Figures 1 to 4 As shown, a steel space frame pole reinforcement device includes: The outer tube 2 is coaxially sleeved on the outer wall of the main rod 1, including a first U-shaped tube 8 and a second U-shaped tube 9 coaxially arranged with the main rod 1. The inner walls of the first U-shaped tube 8 and the second U-shaped tube 9 are covered with rubber pads. A clamping mechanism is provided on the outer wall of the outer wrapping tube 2, which is used to attach the inner arc wall of the first U-shaped tube 8 and the inner arc wall of the second U-shaped tube 9 to the outer wall of the main rod 1 respectively, and keep the first U-shaped tube 8 and the second U-shaped tube 9 in mutual contact and positioning. The clamping gap of the clamping mechanism is staggered with the splicing gap of the first U-shaped tube 8 and the second U-shaped tube 9.

[0025] In this way, when reinforcement of the steel grid frame poles is required, the first U-shaped tube 8 and the second U-shaped tube 9 are directly clamped to the outer wall of the main pole 1, with the ends of the first U-shaped tube 8 and the second U-shaped tube 9 abutting against each other, and the rubber pads covering the inner walls of the first U-shaped tube 8 and the second U-shaped tube 9 completely fitting against the main pole 1. With the clamping mechanism, the first U-shaped tube 8 and the second U-shaped tube 9 are clamped and positioned, ensuring a tight fit between them and the outer wall of the main pole 1. Furthermore, the clamping gap of the clamping mechanism is staggered with the splicing gap between the first U-shaped tube 8 and the second U-shaped tube 9, thus enabling reinforcement of the main pole 1 even without welding, giving the main pole good bending resistance. This improves reinforcement quality, reduces safety risks, and significantly shortens the reinforcement period. Moreover, thanks to the rubber pads, even if the clamping mechanism only applies radial force to the outer covering tube 2, the outer covering tube 2 can still maintain good axial stability.

[0026] Furthermore, the inner diameters of the first U-shaped tube 8 and the second U-shaped tube 9 are the same as the outer diameter of the main rod 1. The inner arc sides of the first U-shaped tube 8 and the second U-shaped tube 9 are spliced ​​together to form a complete cylindrical channel for clamping the main rod 1.

[0027] Furthermore, the clamping mechanism includes a third U-shaped tube 10 and a fourth U-shaped tube 11. The inner diameter of the third U-shaped tube 10 and the fourth U-shaped tube 11 is the same as the outer diameter of the first U-shaped tube 8 and the second U-shaped tube 9. Fastening plates 3 are respectively installed at both ends of the third U-shaped tube 10 and the fourth U-shaped tube 11. The fastening plates 3 at both ends of the third U-shaped tube 10 and the fastening plates 3 on both sides of the fourth U-shaped tube 11 are detachably connected by bolts 4.

[0028] Furthermore, a washer 7 is provided between the nut 5 of the bolt 4 and the fastening plate 3.
