Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a profiled steel beam and a building steel structure. Background Technology

[0002] In the field of steel structure construction, channel steel beams are widely used in applications such as beam bottom formwork reinforcement due to their excellent mechanical properties and structural stability. In the prior art disclosed in CN103711244B, a rectangular steel frame is formed by welding equilateral angle steel between the front and rear crossbeams and the left and right longitudinal beams. Horizontal ribs, secondary crossbeams, upper purlins, lower purlins, and diagonal braces are then installed on the channel steel beams to improve the overall strength of the floor slab and construction efficiency. However, in this technical solution, the strengthening and connection of the channel steel beams mainly rely on welding processes. On-site construction requires high welding quality, and the welding process is easily affected by environmental factors, which may reduce the strength and durability of the connection points.

[0006] Two connectors are provided, one connector is connected to one end of the two profiles along the second direction, and the other connector is connected to the other end of the two profiles along the second direction; the connector is provided with two first receiving grooves on the side near the profile, and the webs of the two profiles are disposed in the corresponding first receiving grooves;

[0007] A first fastener is inserted through the connector and the web along the first direction;

[0013] In one embodiment, the profiled steel beam further includes a first buffer member disposed within the first receiving groove and located between the web and the connecting plate.

[0014] In one embodiment, the flange is provided with a plurality of fourth through holes spaced apart along the second direction; the profile steel beam further includes a positioning pin, which passes through the fourth through hole closest to the connector and abuts against the connector.

[0015] In one embodiment, the groove is provided on the opposite sides of both profiles;

[0016] The groove is provided with a plurality of reinforcing ribs arranged at intervals along the second direction.

[0017] In one embodiment, a second receiving groove is formed between two adjacent reinforcing ribs, and the profile steel beam further includes a second buffer member disposed in the second receiving groove.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] Firstly, referring to Figure 1 As shown, this application embodiment provides a profile steel beam 100, which includes two profiles 10, two connectors 20, a first fastener 30, and a second fastener 40.

[0036] Two profiles 10 are disposed opposite each other along a first direction X; at least one side of each profile 10 along the first direction X is provided with a groove 10a, for example, the profile 10 is provided with a groove 10a on one side along the first direction X, or the profile 10 is provided with grooves 10a on both sides along the first direction X. The profile 10 includes a web 11 and flanges 12 provided on both sides of the web 11 along a second direction Y; the first direction X and the second direction Y are perpendicular. Of the two connectors 20, one connector 20 is connected to one end of the two profiles 10 along the second direction Y, and the other connector 20 is connected to the other end of the two profiles 10 along the second direction Y. Figure 1 and Figure 2 As shown, the connector 20 has two first receiving grooves 20a on the side near the profile 10, and the webs 11 of the two profiles 10 are disposed in the corresponding first receiving grooves 20a. In other words, the end of the web 11 near the connector 20 is embedded (or locked) in the first receiving groove 20a. The first fastener 30 passes through the connector 20 and the web 11 along the first direction X. The second fastener 40 is disposed between the two connectors 20 and passes through the two profiles 10 along the first direction X.

[0037] It is understood that the number of first fasteners 30 is at least four, with at least one first fastener 30 passing through one end web 11 of a profile 10 and the corresponding connector 20. It is also understood that the number of first fasteners 30 can be eight, twelve, or sixteen. When the number of first fasteners 30 is eight, two first fasteners 30 pass through one end web 11 of a profile 10 and the corresponding connector 20. The number of second fasteners 40 can be one or more. When the number of second fasteners 40 is multiple, these multiple second fasteners 40 can be evenly arranged along the second direction Y. For example, the first fastener 30 can be a bolt nut or a stud nut, and the second fastener 40 can be a bolt nut or a stud nut.

[0038] In one embodiment, such as Figure 2 As shown, the connector 20 includes a connecting plate 21, two first extension plates 22, and two second extension plates 23. The two first extension plates 22 are located on one side of the connecting plate 21 along the second direction Y, that is, on the side of the connecting plate 21 near the profile 10. The two first extension plates 22 are respectively connected to both ends of the connecting plate 21 along the first direction X. The two second extension plates 23 are located on one side of the connecting plate 21 along the second direction Y, that is, on the side of the connecting plate 21 near the profile 10. The two second extension plates 23 are spaced apart between the two first extension plates 22. A first receiving groove 20a is formed between the first extension plate 22 and the adjacent second extension plate 23; the first extension plate 22 has a first through hole (not shown), the second extension plate 23 has a second through hole (not shown), and the web plate 11 has a third through hole (not shown). A first fastener 30 passes through the first through hole, the second through hole, and the third through hole to connect the web plate 11 and the connector 20.

[0039] The above configuration can simplify the structure of the connector 20, which helps to improve the structural strength and durability of the profile steel beam 100 while reducing manufacturing difficulty and cost.

[0040] In one embodiment, the connecting plate 21, the first extension plate 22, and the second extension plate 23 are an integral structure.

[0041] In one embodiment, both the first extension plate 22 and the second extension plate 23 are welded to the connecting plate 21.

[0042] It should be noted that the thickness of the connecting plate 21 can be precisely calculated to ensure that it will not deform when subjected to large loads.

[0043] In one embodiment, the profile steel beam 100 further includes a first buffer member 50, which is disposed within a first receiving groove 20a and located between the web 11 and the connecting plate 21. By providing the first buffer member 50, a buffer can be formed between the end of the web 11 and the connecting plate 21, avoiding direct hard contact between the two, and also reducing the impact of impact forces caused by load changes.

[0044] For example, the first buffer 50 may be a rubber buffer. The design principle is to absorb and disperse the impact of external loads through the elastic properties of the rubber material, thereby protecting the connection from excessive stress.

[0045] Understandably, the fastening force of the first fastener 30 and the second fastener 40 can be verified by experiments to ensure that the connection of the profile steel beam 100 is firm and reliable.

[0046] In one embodiment, the flange 12 is provided with a plurality of fourth through holes 121 arranged at intervals along the second direction Y; the profile steel beam 100 also includes a positioning pin 60, which passes through the fourth through hole 121 closest to the connector 20 and abuts against the connector 20. By providing the positioning pin 60, the insertion depth of the web plate 11 in the first receiving groove 20a can be positioned when assembling the connector 20, which facilitates the rapid assembly of the first fastener 30.

[0047] In one embodiment, the diameter of the fourth through hole 121 may be slightly larger than the diameter of the locating pin 60 to facilitate quick positioning and installation.

[0048] Understandably, the position of the fourth through hole 121 can be precisely designed to ensure that after the positioning pin 60 is inserted into the fourth through hole 121, the positioning pin 60 abuts against the connector 20, and the first through hole, the second through hole and the third through hole are aligned.

[0049] In one embodiment, a positioning hole (not shown) may also be provided on the connector 20, and a positioning pin 60 is also inserted into the positioning hole. The positioning pin 60 can be made of high-strength steel, and its hardness and wear resistance can be improved through heat treatment, thereby ensuring that it will not deform or be damaged during long-term use. The end of the positioning pin 60 is designed to be cylindrical, which facilitates quick alignment when inserted into the fourth through hole 121. The fit between the positioning pin 60, the fourth through hole 121, and the positioning hole has been verified through multiple experiments to ensure that it can achieve accurate positioning and form a stable locking structure during installation.

[0050] In one embodiment, reference Figure 1 and Figure 4 As shown, each of the two profiles 10 has a groove 10a on its opposite side. Multiple reinforcing ribs 70 are arranged at intervals along the second direction Y within the groove 10a. By providing the reinforcing ribs 70, the structural strength of the steel beam can be improved.

[0051] It is understandable that the reinforcing rib 70 and the profile 10 can be connected by welding.

[0052] In one embodiment, a second receiving groove 10b is formed between two adjacent reinforcing ribs 70, and the profile steel beam 100 also includes a second buffer member 80 disposed within the second receiving groove 10b. By providing the second buffer member 80, a better buffer can be formed between the profile steel beam 100 and the adjacent structure, and the friction between the profile steel beam 100 and the adjacent structure can be enhanced. In addition, by embedding the second buffer member 80 between the profile steel beam 100 and the adjacent structure, the connection between the profile steel beam 100 and the adjacent structure is made tighter, effectively reducing loosening caused by vibration or load changes.

[0053] For example, the second buffer 80 can be made of a polymer material. In this way, the second buffer 80 has good wear resistance and anti-aging properties, and can maintain stable performance during long-term use.

[0054] In one embodiment, reference Figure 1 and Figure 3 As shown, the end of the second buffer member 80 away from the web plate 11 protrudes from the second receiving groove 10b. In this way, a better buffer can be formed between the profile steel beam 100 and the adjacent structure, while also enhancing the friction between the profile steel beam 100 and the adjacent structure.

[0055] In one embodiment, from the center of the stiffener 70 to both sides along the third direction Z, the distance between the surface of the stiffener 70 away from the web 11 and the web 11 gradually increases; the third direction Z is perpendicular to the first direction X and the second direction Y. Thus, while ensuring structural strength, it is beneficial to reduce the amount of material used for the stiffener 70, thereby reducing costs and overall weight.

[0056] In one embodiment, the profile 10 is an I-beam or a channel steel. Here, channel steel refers to C-shaped channel steel.

[0057] In one embodiment, the installation process of the profile steel beam 100 provided in this application is as follows: First, two symmetrically arranged profiles 10 are placed in predetermined positions. Then, a second buffer member 80 is embedded in the second receiving groove 10b. The size and material of the second buffer member 80 are selected to provide sufficient friction between the profile 10 and adjacent structural members, reducing loosening caused by vibration. Next, the connector 20 is fixed to the end of the profile 10 by the first fastener 30. The tightening force of the first fastener 30 is adjusted to ensure a firm and reliable connection between the connector 20 and the profile 10. The positional relationship between the positioning hole on the connector 20 and the fourth through hole 121 is precisely designed to ensure that the positioning pin 60 can be smoothly inserted and achieve the locking function. Finally, the positioning pin 60 is inserted into the fourth through hole 121 and aligned with the positioning hole on the connector 20 to complete the locking operation. It is understood that the positioning pin 60 can also be assembled before assembling the first fastener 30. In this application embodiment, the entire installation process does not require welding, simplifying the on-site operation process and significantly shortening the construction time.

[0058] During long-term use, the profile steel beam 100 provided in this application embodiment exhibits excellent stability and durability. The application of the reinforcing rib 70 not only optimizes the mechanical properties of the profile 10 but also reduces material costs. The introduction of the first buffer 50 effectively mitigates the impact of load changes, significantly improving structural stability. The precise fit design between the fourth through hole 121 and the positioning pin 60 makes the installation process simpler and faster, meeting the needs of modern buildings for efficient construction. The wear resistance and anti-aging properties of the second buffer 80 further extend the service life of the profile steel beam 100. The thickness of the connector 20 and the position of the bolt holes are precisely calculated to ensure that it will not deform under large loads, further improving construction efficiency.

[0059] Secondly, embodiments of this application provide a building steel structure, including the profiled steel beam 100 in any embodiment of the first aspect. Exemplarily, this building steel structure can be applied in building construction to reinforce the bottom formwork of the beam, thereby ensuring structural stability and safety during construction, with the profiled steel beam 100 serving as a core supporting component.

[0060] The aforementioned steel structure, by incorporating two profiles 10, enhances the structural strength of the profiled steel beam 100. By installing two connectors 20 at each end of the profile 10, the web 11 of the profile 10 can be secured within the first receiving groove 20a of the connector 20. Furthermore, a first fastener 30 passes through the connector 20 and the web 11, connecting the two ends of the two profiles 10. Additionally, a second fastener 40 connects the middle sections of the two profiles 10. In summary, the aforementioned profiled steel beam 100 is easy to assemble, requiring no welding. This not only avoids the problems of insufficient strength and durability caused by poor welding quality but also significantly shortens on-site construction time, thereby improving construction efficiency.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
