Description

Technical Field

[0001] This utility model relates to H-shaped cross-section columns, specifically to a high-performance plate non-contact reinforcement method for H-shaped cross-section columns. Background Technology

[0002] The cross-sectional properties of H-shaped sections give them excellent bending resistance, making them suitable for both bending and compression members. Furthermore, H-shaped sections offer high material utilization during manufacturing, reducing material waste, and are therefore used in many engineering projects.

[0003] Ultra-high performance concrete (UHPC) is a cement-based composite material with strain-hardening characteristics, possessing high strength, high toughness, and high durability. Using UHPC to enlarge the cross-section of beam members improves their load-bearing capacity, stiffness, and corrosion resistance, with limited increase in the member's self-weight and lower maintenance costs. Carbon fiber reinforced polymer (CFRP) is lightweight, high-strength, and corrosion-resistant. Wrapping and bonding transverse or longitudinal CFRP to the outside of beams and columns can suppress buckling and improve member stability. High-performance panels (UHPC precast panels, CFRP panels) prepared from these materials are used to strengthen H-section columns, effectively improving the structural performance of the members and offering advantages such as convenient and quick construction, and the reinforcement materials resisting corrosion and fatigue without special treatment. Currently, high-performance panels (UHPC precast panels, CFRP panels) are typically reinforced by bonding them to the surface of components using adhesives. This method has the following limitations: (1) the adhesive layer is susceptible to environmental factors, leading to reduced bonding strength and durability; (2) the reinforcement effect largely depends on the bonding process, making it difficult to strictly control construction quality; (3) when the reinforced component is large, the anchoring ends of the reinforced panels are prone to peeling failure. These limitations prevent the full utilization of the material advantages of high-performance panels. In addition, some researchers have pre-drilled holes in the high-performance panels and the original components, fixing them with bolts to strengthen the end anchoring of the high-performance panels. While this method avoids the problems associated with adhesive reinforcement, drilling weakens both the component and the high-performance panels. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-performance non-contact reinforcement H-section column for sheet metal. This high-performance non-contact reinforcement H-section column for sheet metal allows for full utilization of the material advantages of high-performance sheet metal (UHPC precast panels, CFRP panels) without weakening the sheet metal.

[0005] The purpose of this utility model is achieved through the following technical solution: This high-performance plate non-contact reinforcement H-shaped section column includes an H-shaped section column body and a C-shaped sleeve assembly. Both ends of the wing plate of the H-shaped section column body are provided with high-performance plates, and the H-shaped section column body and the high-performance plates are fixed together by the C-shaped sleeve assembly.

[0006] The C-shaped clamp assembly includes an angle steel and a pair of C-shaped clamps. The two C-shaped clamps are arranged opposite each other and fixed by a first bolt assembly. The angle steel is set at one end of the flange of the H-shaped cross-section column body, and the angle steel is located between the C-shaped clamp and the H-shaped cross-section column body. The corresponding angle steel part that is in contact with the flange of the H-shaped cross-section column body is fixed to the C-shaped clamp by a second bolt assembly. At the same time, the two C-shaped clamps and the angle steel clamp the high-performance plate together.

[0007] Preferably, the C-shaped clamp assembly has multiple sets, and the multiple C-shaped clamp assemblies are evenly distributed along the axial direction of the H-shaped cross-section column body.

[0008] Preferably, each C-shaped clamp assembly has four angle steels, which are located at the four corners of the H-shaped cross-section column body.

[0009] Preferably, the inner side of the angle steel and the outer side that is in contact with the high-performance plate are both provided with a first groove.

[0014] This invention has the following advantages over the prior art:

[0015] This utility model relates to a non-contact reinforcement method for H-section columns using high-performance sheet metal. The high-performance sheet metal and the H-section column are fixed together via a unique C-shaped clamp assembly. This fully utilizes the high strength, high toughness, and strong corrosion resistance of the high-performance sheet metal to enhance the load-bearing and deformation capacity of the H-section column, improve stress distribution within the column member, and increase its stability, thus achieving the reinforcement purpose. Furthermore, on-site installation requires no drilling, welding, or bonding, simplifying construction without weakening the component. Except for the high-performance sheet metal, all components are steel, with no adhesive layer, making it less affected by environmental factors and highly durable. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, this high-performance plate non-contact reinforcement of H-section columns includes an H-section column body and a C-shaped clamp assembly. Both ends of the flange of the H-section column body are provided with high-performance plates, and the H-section column body and the high-performance plates are fixed together by the C-shaped clamp assembly. The C-shaped clamp assembly includes an angle steel and a pair of C-shaped clamps, which are arranged opposite each other and fixed by a first bolt assembly. The angle steel is located at one end of the flange of the H-section column body, between the C-shaped clamp and the H-section column body. The portion of the angle steel in contact with the flange of the H-section column body is fixed to the C-shaped clamp by a second bolt assembly. Simultaneously, the two C-shaped clamps and the angle steel clamp the high-performance plates together.

[0024] Specifically, in this embodiment, both the angle steel and the C-shaped clamps in the C-shaped clamp assembly are made of steel. The angle steel is L-shaped, and each set of C-shaped clamps contains four angle steels. When the high-performance sheet metal is used to set the ends of the flanges of the H-shaped cross-section column body to form a cuboid column, the four angle steels in each set are respectively placed at the four corners of the column body and then fixed by a pair of C-shaped clamps. These pairs of C-shaped clamps are fixed together by a first bolt assembly, while the portions of the angle steels that are in contact with the sides of the flanges of the H-shaped cross-section column body are fixedly connected by a second bolt C-shaped clamp. In this way, there is no need to drill holes in the high-performance sheet metal, thus preserving its performance and fully utilizing its material advantages. Simultaneously, the use of angle steel and C-shaped clamps for clamping and fixing between the H-shaped cross-section column body and the high-performance sheet metal eliminates the need for existing adhesive layers, avoiding problems such as insufficient durability of the adhesive layer and easy peeling of the anchoring end material.

[0025] The C-shaped clamp assembly has multiple sets, and these multiple C-shaped clamp assemblies are evenly distributed along the axial direction of the H-shaped cross-section column body. For example... Figure 1 and Figure 2 As shown, this embodiment uses three sets of C-shaped clamp components. These three sets of C-shaped clamp components anchor high-performance plates along the entire length of the column in the weak axis direction of the H-shaped cross-section column to form a reinforced structure and improve the stress performance of the column components.

[0026] The inner side of the angle steel (i.e., the side facing the H-shaped column body and the CFRP plate) and the outer side in contact with the high-performance plate are both provided with first grooves. The inner side of the C-shaped sleeve (i.e., the side facing the high-performance plate) is provided with a second groove. The grooves increase the friction between the contacting phases, further improving the stability of the structure.

[0027] The first bolt assembly includes two first bolts, and the connection between each pair of C-shaped clamps is achieved by the two first bolts. Each first bolt is equipped with a locking nut. Figure 3 and Figure 4 As shown, the connecting part of the C-shaped sleeve has two screw holes that match the first bolt. The corresponding connecting parts of the two C-shaped sleeves are arranged opposite each other, and the shank of the first bolt passes through the two opposite screw holes in sequence and is locked with a nut, thereby ensuring that the two C-shaped sleeves can clamp and fix the H-shaped cross-section column body and the high-performance plate together.

[0028] Each group of second bolt assemblies has four second bolts, which are arranged in a matrix. For example... Figure 4 and Figure 5 As shown, both the C-shaped sleeve and the angle steel are provided with matrix-distributed screw holes that match the second bolt. The angle steel and the C-shaped sleeve are fixed by the second bolt, thereby further improving the reliability of the structure.

[0029] The connecting end of the C-shaped clamp is equipped with stiffening ribs. The stiffening ribs increase the strength of the C-shaped clamp and further improve its stability.

[0030] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
