Description

Technical Field

[0001] The utility model relates to the technical field of steel components, in particular to a high-strength compression-resistant steel component. Background Art

[0002] Steel components refer to composite steel structure components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected by connectors. They are widely used in automobiles, railway vehicles, building doors and windows, transportation, shelves, electrical cabinets, highway guardrails, building steel structures, containers, steel formwork and scaffolding, solar brackets, shipbuilding, bridges, transmission towers and other fields.

[0003] The existing Chinese patent (publication number: CN220506484U) discloses a recyclable circulating steel member with strong radial compressive resistance, including a lower cross plate, a support plate is fixedly installed on the upper end of the lower cross plate, an upper cross plate is fixedly installed on the upper end of the support plate, a corrugated support frame is fixedly installed between the lower cross plate and the upper cross plate, a through hole one is opened on the lower cross plate, a through hole two is opened on the upper cross plate, vertical support plates are fixed at the crest and trough of the corrugated support frame, the vertical support plate fixedly installed at the crest of the corrugated support frame is fixedly connected to the lower cross plate, and the vertical support plate fixedly installed at the trough of the corrugated support frame is fixedly connected to the upper cross plate, and the through hole one is symmetrically distributed on both sides of the axis of the lower cross plate.

[0004] The above-mentioned steel components rely on the wavy support frame to disperse the pressure during use. However, this structure can only disperse the pressure to a certain extent in the vertical direction through the wave-like ups and downs. The ability to disperse the pressure from different angles and directions, especially the lateral pressure, is relatively weak. Although the wavy support frame is fixed with vertical support plates at the crests and troughs, these support plates mainly provide support force in the vertical direction, and have limited effect on dispersing the pressure at the edges and key connection parts of the steel components. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength compression-resistant steel component to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides a high-strength compression-resistant steel member, including an upper transverse plate, a lower transverse plate and a connecting plate, wherein the upper transverse plate, the lower transverse plate and the connecting plate constitute an I-shaped support structure, including:

[0007] A plurality of first support members are symmetrically arranged on both sides of the connecting plate with the axis of the connecting plate as the center, and the plurality of first support members are evenly spaced and distributed in a linear array along the transverse axis direction of the connecting plate, the opening directions of two adjacent first support members are opposite, and the shape of the first support member is an arch;

[0008] A plurality of second support members are connected inside the first support member, and the opening direction of the second support members is the same as the opening direction of the second support members. The second support members are arranged in a trapezoidal shape.

[0009] Furthermore, a reinforcement piece is provided between two adjacent first support members, and the two ends of the reinforcement piece are respectively connected to the upper horizontal plate and the lower horizontal plate. The inclination angles of the two adjacent reinforcement pieces are opposite and they cooperate with the upper horizontal plate and the connecting plate to form a trapezoidal support structure.

[0010] Furthermore, a fixing member is detachably connected to the second supporting member, a third positioning plate is connected to one side of the fixing member, a third positioning bolt is provided on the third positioning plate, and the fixing member is detachably connected to the second supporting member via the third positioning bolt.

[0011] Furthermore, first positioning plates are connected to the four corners of both ends of the first support member, and first positioning bolts are arranged on the first positioning plates. The first positioning plates are detachably arranged between the upper horizontal plate and the lower horizontal plate by using the first positioning bolts.

[0012] Furthermore, two second positioning plates which are symmetrical to each other are connected inside the second support member, and second positioning bolts are arranged on the second positioning plates. The second positioning plates are detachably arranged between the upper horizontal plate and the lower horizontal plate by the second positioning bolts.

[0013] Furthermore, the upper transverse plate and the lower transverse plate are both provided with a plurality of connecting through holes, and the plurality of connecting through holes are distributed in a rectangular array.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The arched design and linear array distribution of the first support can effectively disperse the pressure after being transmitted from the upper and lower horizontal plates. Multiple first support members work together to evenly disperse the pressure along the length of the steel member, reducing the risk of local deformation or damage due to excessive pressure. At the same time, the design of the opening directions of adjacent first support members in opposite directions allows the first support members on both sides of the steel member to restrain each other when the steel member is subjected to lateral force, thereby enhancing the lateral stability of the steel member.

[0016] 2. The trapezoidal structure of the second support is connected to the inside of the first support, providing strong internal support for the first support. When the first support is subjected to external pressure, the hypotenuse and bottom edge of the second support bear the pressure together, enhancing the compressive capacity of the first support, thereby improving the strength of the entire steel structure. When the external pressure is transmitted to the second support through the first support, its trapezoidal structure can disperse the pressure again, so that the pressure can be more evenly distributed throughout the steel structure.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a high-strength compression steel member, including an upper transverse plate 1, a lower transverse plate 2 and a connecting plate 3, wherein the upper transverse plate 1, the lower transverse plate 2 and the connecting plate 3 constitute an I-shaped support structure, including:

[0024] A plurality of first support members 4 are symmetrically arranged on both sides of the connecting plate 3 with the axis of the connecting plate 3 as the center, and the plurality of first support members 4 are evenly spaced and distributed in a linear array along the transverse axis direction of the connecting plate 3, and the opening directions of two adjacent first support members 4 are opposite, and the shape of the first support members 4 is an arch;

[0025] A plurality of second support members 5 are connected to the first support member 4, and the opening direction thereof is the same as the opening direction of the second support member 5. The second support member 5 is arranged in a trapezoidal shape.

[0026] In specific implementation: when subjected to external pressure, the upper horizontal plate 1 and the lower horizontal plate 2 first bear the pressure and transfer it to the connecting plate 3. Since the first support member 4 is symmetrically arranged on both sides of the connecting plate 3 with the axis of the connecting plate 3 as the center, the pressure will be further transmitted to the first support member 4 at this time. The arched shape of the first support member 4 enables it to be like an arc-shaped force transmission channel. When the pressure acts on the top of the arch, according to the principle of mechanics, the force will be dispersed along the curve of the arch, and part of the pressure will be transmitted to both sides along the tangent direction of the arch, thereby reducing the concentration of pressure on the steel structure. Since multiple first support members 4 are distributed in a linear array with equal spacing along the transverse axis direction of the connecting plate 3, they can work together to evenly disperse the pressure in the length direction of the entire steel structure, avoiding deformation or damage caused by excessive local pressure. The opening directions of two adjacent first support members 4 are opposite. When the steel structure is subjected to lateral force, the first support member 4 on one side will be squeezed, while the first support member 4 on the other side will be stretched;

[0027] The second support member 5 is connected to the inside of the first support member 4, and its trapezoidal shape provides internal support for the first support member 4. The trapezoidal structure has the characteristics of high stability. When the first support member 4 is subjected to external pressure, the hypotenuse and the bottom edge of the second support member 5 can jointly bear the pressure. The second support member 5 not only enhances the strength of the first support member 4, but also participates in the force transmission and dispersion process. When the first support member 4 transmits the external pressure to the internal second support member 5, the trapezoidal structure of the second support member 5 can disperse the pressure again.

[0028] refer to Figures 1 to 3 A reinforcing member 6 is arranged between two adjacent first supporting members 4, and the two ends of the reinforcing member 6 are respectively connected to the upper horizontal plate 1 and the lower horizontal plate 2. The inclination angles of the two adjacent reinforcing members 6 are opposite, and they are used in conjunction with the upper horizontal plate 1 and the connecting plate 3 to form a trapezoidal supporting structure.

[0029] In specific implementation, the setting of the reinforcement 6 increases the support force of the steel member in the lateral direction. When the steel member is subjected to vertical pressure, the distance between the upper horizontal plate 1 and the lower horizontal plate 2 may be shortened due to the pressure, and the reinforcement 6 connected between the two can effectively resist such deformation; when subjected to lateral force, the reinforcement 6 can provide additional lateral support. The inclination angles of two adjacent reinforcements 6 are opposite, so that they can restrain each other in the horizontal direction and resist the deformation caused by the lateral force.

[0030] refer to Figure 3 and Figure 4 The second support member 5 is detachably connected to a fixing member 7 , one side of the fixing member 7 is connected to a third positioning plate 12 , the third positioning plate 12 is provided with a third positioning bolt 13 , and the fixing member 7 is detachably connected to the second support member 5 through the third positioning bolt 13 .

[0031] During specific implementation, the fixing member 7 is first provided to facilitate better pressure dispersion and further improve the compressive resistance. Secondly, the fixing member 7 is detachably connected to the second support member 5 through the third positioning bolt 13, so that the installation operation can be carried out very conveniently when assembling the steel structure.

[0032] refer to Figure 3 The first support member 4 is connected to first positioning plates 8 at both ends and four corners, and the first positioning plates 8 are provided with first positioning bolts 9. The first positioning plates 8 are detachably arranged between the upper horizontal plate 1 and the lower horizontal plate 2 by means of the first positioning bolts 9.

[0033] In specific implementation, when installing the steel structure, the first support member 4 with the first positioning plate 8 is connected to the upper cross plate 1 and the lower cross plate 2 through the first positioning bolt 9, and the operation is simple and quick.

[0034] refer to Figure 3 Two second positioning plates 10 symmetrical to each other are connected in the second support member 5 , and second positioning bolts 11 are provided on the second positioning plates 10 . The second positioning plates 10 are detachably arranged between the upper horizontal plate 1 and the lower horizontal plate 2 through the second positioning bolts 11 .

[0035] In specific implementation, this arrangement facilitates fixing the second support member 5 by using the second positioning plate 10 in cooperation with the second positioning bolt 11 .

[0036] refer to Figure 1 A plurality of connecting through holes 14 are provided on both the upper horizontal plate 1 and the lower horizontal plate 2, and the plurality of connecting through holes 14 are distributed in a rectangular array.

[0037] Specifically, this arrangement facilitates the connection of the utility model with other supporting workpieces.

[0038] Working principle: When subjected to external pressure, the upper horizontal plate 1 and the lower horizontal plate 2 first bear the pressure and transfer it to the connecting plate 3. Since the first support member 4 is symmetrically arranged on both sides of the connecting plate 3 with the axis of the connecting plate 3 as the center, the pressure will be further transmitted to the first support member 4. The arched shape of the first support member 4 enables it to be like an arc-shaped force transmission channel. When the pressure acts on the top of the arch, according to the principle of mechanics, the force will be dispersed along the curve of the arch, and part of the pressure will be transmitted to both sides along the tangent direction of the arch, thereby reducing the concentration of pressure on the steel structure. Since multiple first support members are distributed in a linear array with equal spacing along the transverse axis direction of the connecting plate 3, they can work together to evenly disperse the pressure in the length direction of the entire steel structure, avoiding deformation or damage caused by excessive local pressure. The opening directions of two adjacent first support members 4 are opposite. When the steel structure is subjected to lateral force, the first support member 4 on one side will be squeezed, while the first support member 4 on the other side will be stretched;

[0039] The second support member 5 is connected to the inside of the first support member 4, and its trapezoidal shape provides internal support for the first support member 4. The trapezoidal structure has the characteristics of high stability. When the first support member 4 is subjected to external pressure, the hypotenuse and the bottom edge of the second support member 5 can jointly bear the pressure. The second support member 5 not only enhances the strength of the first support member 4, but also participates in the force transmission and dispersion process. When the first support member 4 transmits the external pressure to the internal second support member 5, the trapezoidal structure of the second support member 5 can disperse the pressure again.
