Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a primary and secondary beam connection structure. Background Technology

[0002] With social progress and development, construction technology is constantly improving, and existing prefabricated frame structures with primary and secondary beam connections basically meet people's needs. However, currently, the connection between primary and secondary beams in steel structure buildings mainly adopts a fully welded method to form the connection node structure. Such a frame structure requires very precise alignment between components. Steel structures are large and heavy, and once welded, they cannot be moved; moreover, on-site welding efficiency is low, which can easily affect the progress of the project. In addition, welding requires heating to a certain temperature before it can be carried out, and the heating process can cause problems such as deformation and cracking due to thermal stress. Therefore, to address the shortcomings of current prefabricated frame structures with primary and secondary beam connections, a new type of primary and secondary beam connection structure has been invented. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a main and secondary beam connection structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A primary and secondary beam connection structure includes a primary beam and a secondary beam. The primary beam includes a main plate and side plates located on the upper and lower sides of the main plate. One side plate is bent to form a first connecting plate, and the other side plate is bent to form a second connecting plate. A first riveting steel plate is provided on the main plate, and a second riveting steel plate is provided on the secondary beam. The second riveting steel plate is riveted to the first riveting steel plate. The upper and lower ends of the secondary beam are bent to form a third connecting plate and a fourth connecting plate, respectively. The third connecting plate is riveted to the first connecting plate, and the fourth connecting plate is riveted to the second connecting plate.

[0006] Preferably, three riveting points are provided between the first riveting steel plate and the second riveting steel plate.

[0007] Preferably, the upper and lower ends of the riveted steel plate are arc-shaped.

[0008] Preferably, the riveting steel plate is concave on the outside and convex on the inside.

[0009] Preferably, the cross-section of the secondary beam is a right trapezoidal shape.

[0010] Preferably, the secondary beam is provided with a plurality of fixing holes.

[0011] Preferably, the side plate is provided with through holes.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting a first riveting steel plate on the main beam and a second riveting steel plate on the secondary beam, a piercing rivet, driven by a hydraulic piercing rivet punch, pierces the first riveting steel plate. Simultaneously, the piercing rivet causes the second riveting steel plate to plastically deform and enter the piercing riveting die. Under the action of the punch and boss, the legs of the piercing rivet expand to both sides and embed into the second riveting steel plate, thus making the first and second riveting steel plates tightly connected. By setting a first and second connecting plate on the main beam and a third and fourth connecting plate on the secondary beam, the piercing rivet, driven by the piercing rivet punch, tightly connects the first and third connecting plates, and the second and fourth connecting plates, preventing loosening between the main beam and the secondary beam, thus making the connection between the main beam and the secondary beam even stronger.

[0014] 2. By setting the upper and lower ends of the riveted steel plate to be arc-shaped, stress can be better dispersed, reducing stress concentration in the connection part and the risk of damage to the connection parts due to stress concentration, thereby improving the strength and stability of the connection. By setting the cross-section of the secondary beam to a right-angled trapezoidal shape, this inclined connection method allows for a tighter connection between the main beam and the secondary beam, thereby improving the stability and load-bearing capacity of the entire structure.

Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] like Figures 1 to 7 As shown, a main-secondary beam connection structure includes a main beam 1 and a secondary beam 2. The main beam 1 includes a main plate 11 and side plates 12. The side plates 12 are vertically located on the upper and lower sides of the main plate 11. The side plates 12 have a size of 90mm. The upper side plate is bent vertically downward to form a first connecting plate 13, and the lower side plate is bent vertically upward to form a second connecting plate 14. The first connecting plate 13 and the second connecting plate 14 are mainly used to connect the main beam 1 and the secondary beam 2 into a whole, thereby achieving a more efficient structural connection and functional integration. In addition, four through holes 121 are equidistantly arranged on the side plates 12. The through holes 121 not only facilitate installation and ensure that the steel plates are securely fixed in the required positions, but also reduce the amount of material used, thereby reducing the self-weight of the structure.

[0028] Furthermore, the main board 11 is provided with a plurality of riveting steel plates 15, the upper and lower ends of which are arc-shaped. The arc-shaped riveting steel plates 15 can better disperse stress, reduce stress concentration in the connection part, and reduce the risk of damage to the connection components due to stress concentration, thereby improving the strength and stability of the connection. In addition, the arc-shaped riveting steel plates 15 not only improve aesthetics but also enhance the safety and durability of the connection components.

[0029] refer to Figure 3 , Figure 4 , Figure 7 As shown, the secondary beam 2 includes a second riveted steel plate 21. The main plate at the middle position of the secondary beam 2 is vertically bent to form the second riveted steel plate 21. The second riveted steel plate 21 is riveted to the first riveted steel plate 15. That is, the piercing rivet is pre-pressed vertically downward under the drive of the hydraulic piercing rivet punch. When the hydraulic piercing rivet punch moves downward, it pushes the piercing rivet to force it to pierce the first riveted steel plate 15. At the same time, the piercing rivet causes the second riveted steel plate 21 to plastically deform and enter the piercing riveting die. As the riveting proceeds, the second riveted steel plate 21 gradually fills the piercing riveting die due to plastic deformation. Under the action of the punch and the boss, the legs of the piercing rivet expand to both sides and embed into the second riveted steel plate 21, so that the piercing rivet is tightly connected with the first riveted steel plate 15 and the second riveted steel plate 21. The riveting of the second riveting steel plate 21 to the first riveting steel plate 15 enhances the tightness and stability of the connection between the main beam 1 and the secondary beam 2, enabling it to withstand greater pressure. The first riveting steel plate 15, driven by the hydraulic piercing riveting punch, exhibits a "concave outer side and convex inner side" configuration, which not only further tightens the connection between the main beam 1 and the secondary beam 2 but also improves the aesthetics of the steel connection. Furthermore, three riveting points are provided between the first riveting steel plate 15 and the second riveting steel plate 21, which better disperses and withstands external forces, thereby improving the stability and safety of the connection between the main beam 1 and the secondary beam 2, and allowing the use of higher-strength steel to suit the structural system.

[0030] refer to Figure 1 , Figure 5 , Figure 6As shown, the secondary beam 2 is provided with a third connecting plate 22 and a fourth connecting plate 23 at both ends. The upper end of the secondary beam 2 is bent downward by 30mm to form the third connecting plate 22, and the lower end of the secondary beam 2 is bent upward by 30mm to form the fourth connecting plate 23. The third connecting plate 22, which is at the same height as the first connecting plate 13, abuts against the first connecting plate 13, and the fourth connecting plate 23, which is at the same height as the second connecting plate 14, abuts against the second connecting plate. That is, the piercing rivet, driven by the hydraulic piercing rivet punch, pierces the third connecting plate 22 and the fourth connecting plate 24 respectively. At the same time, the piercing rivet causes the first connecting plate 13 and the second connecting plate 14 to undergo plastic deformation and enter the piercing riveting die. The piercing riveting die has a punch and a boss. Under the action of the punch and the boss, the legs of the piercing rivet expand to both sides and embed into the first connecting plate 13 and the second connecting plate 14 respectively, so that the first connecting plate 13 and the third connecting plate 22 are tightly connected, and the second connecting plate 14 and the fourth connecting plate 23 are tightly connected. The third connecting plate 22 is riveted to the first connecting plate 13, and the fourth connecting plate 23 is riveted to the second connecting plate 14. This prevents the main beam 1 and the secondary beam 2 from loosening after the riveting steel plates 15 and 21 are connected, making the connection between the main beam 1 and the secondary beam 2 more secure. Furthermore, the riveting of the main beam 1 and the secondary beam 2 uses a cold treatment method, avoiding the risk of igniting flammable materials during welding, and the riveted connection has better ductility under impact or vibration. The riveting of the main beam 1 and the secondary beam 2 allows for large-scale mass production, greatly improving the efficiency of the processing.

[0031] refer to Figure 6 As shown, the secondary beam 2 has a right-angled trapezoidal cross-section. This inclined connection method allows for a tighter connection between the main beam 1 and the secondary beam 2, thereby improving the stability and load-bearing capacity of the entire structure. Furthermore, the secondary beam 2 is provided with several fixing holes 24. The edges of the fixing holes 24 have cross-sections with through holes. The secondary beam passes through the fixing holes 24 and is placed within them. The through holes in the cross-sections prevent the secondary beam from moving or deforming during processing and use, thus ensuring its accuracy and stability.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
