Description

Technical Field

[0001] This utility model relates to the field of building structural components technology, specifically to an adjustable stiffened steel column head protection device. Background Technology

[0002] As a composite structural component integrating high strength, high rigidity, and excellent seismic performance, rigid steel columns have become an indispensable core load-bearing component in modern construction engineering. They are widely used in engineering fields with stringent requirements for structural load-bearing capacity and seismic fortification, such as high-rise buildings, long-span bridges, heavy industrial plants, and super high-rise complexes. Through the synergistic work of the steel frame and concrete, they effectively leverage the high tensile strength of steel and the excellent compressive strength of concrete, significantly improving the overall mechanical performance and disaster resistance of the structure.

[0003] With the development of materials science and construction technology, the manufacturing process of reinforced steel columns has undergone multi-dimensional upgrades. For example, high-strength low-alloy steel is used to optimize the strength of the frame, advanced welding technologies such as submerged arc welding and laser welding ensure the quality of component connections, and digital layout and modular processing technologies improve production precision, resulting in continuous improvements in load-bearing capacity, durability, and construction adaptability. Meanwhile, various countries have established corresponding standards and specifications for the design and construction of reinforced steel columns, clearly defining their design parameters, construction processes, and quality acceptance standards. This further promotes the application of reinforced steel columns in green building and intelligent construction—the recyclable nature of their steel aligns with the concept of sustainable development, while their integration with BIM technology and prefabricated construction effectively shortens the construction cycle.

[0004] However, during the on-site installation and construction of reinforced steel columns, contamination of the column heads can have a significant negative impact on the installation accuracy and welding quality of the next layer of steel columns. Specifically:

[0005] During the concrete pouring process of this layer, due to the lack of effective protection for the column heads, concrete slurry can easily adhere to the column head surface through formwork gaps, vibration splashes, or pouring overflows, forming hardened deposits. This contamination directly leads to a decrease in the fit accuracy of the joint surfaces during the installation of the next layer of steel columns due to the presence of concrete residue, resulting in excessive gaps. This, in turn, causes problems such as deviation of the steel column axis and verticality exceeding tolerances, disrupting the overall stress transmission path of the structure.

[0006] The temporary protective measures currently used, such as covering with plastic film and wrapping with asbestos cloth, are prone to falling off or being damaged by vibration and impact due to their unstable protective effect. Customized steel protective covers have a better protective effect, but they need to be designed and processed separately for column heads of different sizes, which has poor versatility and high cost, and cannot effectively solve the installation and welding quality problems caused by column head contamination.

[0007] The aforementioned technical problems not only restrict the improvement of the construction quality and efficiency of reinforced steel columns, but may also have a potential impact on the long-term safety of the structure. Therefore, it is urgent to develop an improved technical solution that can effectively solve column head contamination and ensure the quality of installation and welding. Utility Model Content

[0008] In view of this, the present invention provides an adjustable stiffened steel column head protection device, which can avoid column head contamination, ensure installation and welding quality, and meet the needs of steel columns of different sizes.

[0009] The technical solution adopted in this utility model is as follows:

[0010] An adjustable stiffened steel column head protection device includes a protection fixing component, a web plate protection sliding component, and a flange protection sliding component;

[0011] The protective fastener is divided into a flange portion and a web portion. The flange portion is used to be fitted onto the head of the rigid steel column, and the web portion covers the web of the head of the rigid steel column. The web protective sliding member has the same cross-sectional shape as the web of the rigid steel column and is used to be fitted onto the web portion of the protective fastener. The flange protective sliding member is fitted onto both ends of the flange portion of the protective fastener.

[0012] Furthermore, the bottom end of the protective fastener is bent upward to form a U-shaped groove, and the bottom ends of the web protective sliding member and the flange protective sliding member are provided with folded edge ribs, which are limited by the U-shaped groove.

[0013] Furthermore, the folded edge rib has a wavy topological configuration, including concave arc segments and convex arc segments, with a smooth transition between the concave and convex arc segments, and the convex arc segments are fitted onto the outer side of the U-shaped groove.

[0014] Furthermore, the outer wall of the convex arc segment extends downward from the bottom end of the protective fastener.

[0015] Furthermore, the concave arc segment extends 2-3 cm into the U-shaped groove.

[0016] Furthermore, the width of the protective fixing member is 5-10 mm larger than the thickness of the stiffened steel column, and the width of the web protective sliding member and the flange protective sliding member is 3-5 mm larger than the width of the web portion and the flange portion of the protective fixing member, respectively.

[0017] Furthermore, the protective fastener, the web plate protective sliding member, and the flange protective sliding member are all made of galvanized steel sheet with a thickness of 0.5 to 1 mm.

[0018] Beneficial effects:

[0019] 1. The protective fixing parts, web plate protective sliding parts, and flange protective sliding parts of this utility model can realize the recyclability of the protection of steel column heads of different sizes, reducing the use and waste of protective parts; at the same time, they can effectively avoid the contamination of steel column heads during concrete pouring, and maximize the installation accuracy and welding quality of the lower steel columns.

[0020] Moreover, this utility model can be mass-produced, is convenient and quick to install, and is easy to operate. While ensuring construction safety, it can reduce construction costs and achieve green and sustainable construction.

[0021] 2. The bottom end of the protective fastener is bent upward to form a U-shaped groove. The bottom end of the web plate protective sliding component and the flange protective sliding component are provided with folded edge ribs. The folded edge ribs are limited by the U-shaped groove to ensure that the fastener and the sliding component can be tightly connected, and to prevent too much cement material from entering the U-shaped groove during concrete pouring, which would affect the recycling of the fastener.

[0022] 3. The concave arc section of this utility model extends 2-3cm into the U-shaped groove, which can further prevent mortar from entering the U-shaped groove during concrete pouring.

[0023] 4. The material of this utility model is galvanized steel plate, which can be made very thin without affecting the pouring construction. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] This utility model provides an adjustable stiffened steel column head protection device, including a protective fixing component 1, a web plate protective sliding component 2, and a flange protective sliding component 3.

[0037] The protective fastener 1 is divided into a flange portion and a web portion. The flange portion is used to fit onto the flange of the stiffened steel column head, and the web portion covers the stiffened steel column head. The web protective sliding component 2 has the same cross-sectional shape as the web of the stiffened steel column and is used to fit onto the web portion of the protective fastener 1. The flange protective sliding component 3 is fitted onto both ends of the flange portion of the protective fastener 1. It should be noted that the "sliding" in the technical names of the web protective sliding component 2 and the flange protective sliding component 3 refers to the relative movement of the web protective sliding component 2 and the flange protective sliding component 3 between stiffened steel column heads of the same model but different sizes, relative to the protective fastener 1.

[0038] like Figure 9 , Figure 10 As shown, the bottom end of the protective fastener 1 is bent upward to form a U-shaped groove 4. The bottom ends of the web protective sliding member 2 and the flange protective sliding member 3 are provided with folded edge ribs 5. The folded edge ribs 5 are limited by the U-shaped groove 4 to ensure that the fastener and the sliding member can be tightly connected, and to prevent too much cement material from entering the U-shaped groove 4 during concrete pouring, which would affect the turnover and utilization of the fastener.

[0039] Specifically, the folded edge rib 5 has a wavy topological structure, including a concave arc segment 6 and a convex arc segment 7. The concave arc segment 6 and the convex arc segment 7 have a smooth transition, and the convex arc segment 7 is fitted onto the outer side of the U-shaped groove 4. The outer wall of the convex arc segment 7 extends downward from the bottom end of the protective fastener 1.

[0040] Preferably, the concave arc segment 6 extends 2-3 cm into the U-shaped groove 4.

[0041] The width of the protective fastener 1 is 5-10 mm larger than the thickness of the stiffened steel column. That is, the width of the flange of the protective fastener 1 is 5-10 mm larger than the thickness of the flange of the stiffened steel column, and the width of the web of the protective fastener 1 is 5-10 mm larger than the thickness of the web of the stiffened steel column, so as to facilitate the protective fastener 1 to be fastened on the stiffened steel column.

[0042] The widths of the web plate protection sliding member 2 and the flange protection sliding member 3 are 3-5 mm larger than the widths of the web plate portion and the flange portion of the protection fixing member 1, respectively, so that the web plate protection sliding member 2 and the flange protection sliding member 3 can be easily locked onto the protection fixing member 1.

[0043] The protective fastener 1, the web plate protective sliding component 2, and the flange protective sliding component 3 are all made of galvanized steel sheet with a thickness of 0.5 to 1 mm.

[0044] This utility model's adjustable stiffened steel column head protection device can be widely applied to H-beam steel columns, cross-shaped steel columns, T-beam steel columns, box-shaped steel columns, and irregularly shaped steel columns. For example... Figure 1 , Figure 5 , Figure 6 As shown, taking a cross-shaped rigid steel column as an example, the protective fastener 1 includes four T-shaped structures, which can be rolled and welded together using a specific mold, such as... Figure 2 As shown, each T-shaped structure is divided into a flange section and a web section. These four T-shaped structures can be respectively fitted onto the four protruding parts of the cruciform stiffened steel column capital. Figure 3 As shown, the web plate protection sliding member 2 is cross-shaped and is pressed into the web plate portion of the protection fixing member 1 from above. Figure 4 As shown, the flange protection sliding member 3 includes eight flange units with the same cross-sectional shape as the flange of the cross-shaped rigid steel column. Each pair forms a group, corresponding to one flange of the cross-shaped rigid steel column, and are pressed into the two ends of the flange of the protection fixing member 1 from above. Similarly, the web plate protection sliding member 2 and the flange protection sliding member 3 can also be rolled and welded together using specific molds.

[0045] like Figure 7 , Figure 8 As shown, the folded edge rib 5 of the web plate protective sliding member 2 is engaged with the U-shaped groove 4 of the web plate of the protective fixing member 1, and the folded edge rib 5 of the flange protective sliding member 3 is engaged with the U-shaped groove 4 of the flange of the protective fixing member 1, thereby preventing excessive cement material from entering the U-shaped groove 4 during concrete pouring.

[0046] For cross-shaped stiffened steel columns of the same model but different sizes, it is only necessary to adjust the relative positional relationship between the web plate protection sliding member 2, the flange protection sliding member 3 and the protection fixing member 1. That is, adjust the web plate protection sliding member 2 and the flange protection sliding member 3 to slide relative to the protection fixing member 1 respectively. This can achieve full coverage of the column head of cross-shaped stiffened steel columns of different sizes, thereby adjusting the protection device to meet the needs of stiffened steel columns of different sizes.

[0047] For other rigid steel columns such as H-type, T-type, box-type, and irregular-shaped columns, it is only necessary to customize the fixed protective fastener 1, web plate protective sliding component 2, and flange protective sliding component 3 according to their cross-sectional shape.

[0048] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
