Description

Technical Field

[0001] This utility model relates to the field of steel truss technology, and more specifically, to a steel truss assembly. Background Technology

[0002] Steel trusses, also known as steel trusses, are a type of skeleton structure made of welded steel bars. A steel truss typically consists of one top chord and two bottom chords arranged in a triangle, connected by two long, wavy, curved web members to form a steel skeleton with an inverted V-shaped cross-section. Steel trusses are made by welding hot-rolled or cold-rolled ribbed steel bars using fully automated high-frequency resistance welding equipment. They possess advantages such as good stability, high rigidity, and reliable quality. In prefabricated buildings, steel trusses are mainly used in steel truss concrete composite slabs. However, existing technologies have the following shortcomings in their application:

[0003] Traditional steel trusses are typically composed of welded top chord steel bars, bottom chord steel bars, and web steel bars. While they can meet the structural stress requirements to a certain extent, their overall stiffness is often limited, leading to insufficient support strength in practical engineering applications.

[0004] Therefore, there is an urgent need for a steel truss assembly to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel truss assembly that can solve the problem that traditional steel trusses are usually composed of welded upper chord steel bars, lower chord steel bars and web steel bars. Although they can meet the structural stress requirements to a certain extent, they often have limited overall stiffness and insufficient support strength.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The application is as follows:

[0008] A steel truss assembly includes a base plate. A plurality of hat-shaped support plates arranged linearly and equidistantly are fixedly installed on the top of the base plate. Each hat-shaped support plate has a first arc-shaped mounting opening, a second arc-shaped mounting opening, and a third arc-shaped mounting opening. A top chord reinforcement is provided within each of the first arc-shaped mounting openings. A first bottom chord reinforcement is provided within each of the second arc-shaped mounting openings. A second bottom chord reinforcement is provided within each of the third arc-shaped mounting openings. Web reinforcement is fixedly welded between the top chord reinforcement and the first bottom chord reinforcement, as well as between the top chord reinforcement and the second bottom chord reinforcement. A first transverse reinforcing plate is fixedly connected between adjacent hat-shaped support plates. An A-shaped reinforcement member is provided between the first transverse reinforcing plate and the base plate.

[0009] The A-shaped reinforcement includes a V-shaped reinforcing plate welded and fixed to the lower surface of the first transverse reinforcing plate, and a second transverse reinforcing plate is transversely welded to the V-shaped reinforcing plate on its two inner surfaces.

[0010] As a preferred technical solution of this application, two reinforcing rods are welded and fixed between each of the two adjacent hat-shaped support plates, and the two reinforcing rods are respectively located on opposite sides of the A-shaped reinforcement.

[0011] As a preferred technical solution of this application, the second arc-shaped mounting opening and the third arc-shaped mounting opening are symmetrically distributed about the central axis of the cap-shaped support plate, and the first arc-shaped mounting opening is located above the second arc-shaped mounting opening and the third arc-shaped mounting opening.

[0012] As a preferred technical solution of this application, the upper chord steel bar, the first lower chord steel bar, and the second lower chord steel bar are all welded and fixed to the hat-shaped support plate.

[0013] As a preferred technical solution of this application, the upper and lower end faces of the A-shaped reinforcement are welded and fixed to the first transverse reinforcement plate and the base plate, respectively.

[0014] As a preferred technical solution of this application, a plurality of the hat-shaped support plates and a plurality of A-shaped reinforcements are linearly staggered, and the hat-shaped support plates are perpendicular to the base plate.

[0015] As a preferred technical solution of this application, several of the A-shaped reinforcement members are located between two web reinforcement bars, and the two web reinforcement bars are arranged opposite to each other.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By combining the base plate, hat-shaped support plate, first transverse reinforcement plate and A-shaped reinforcement, a multi-layer reinforcement structure is formed, which makes the overall stress of the steel truss more reasonable, effectively disperses the load, and greatly improves the compressive, tensile and shear strength of the steel truss, enabling it to withstand greater building loads.

[0018] 2. By setting A-shaped reinforcement members and stiffening rods, the relative displacement of each component is further constrained, which effectively improves the lateral deformation resistance and overall stiffness of the steel truss, making it less prone to torsional deformation during construction and use, and its structural stability is significantly better than that of traditional steel trusses.

[0027] Example:

[0028] like Figure 1-4As shown, this embodiment proposes a steel truss assembly, including a base plate 1. A plurality of hat-shaped support plates 2, arranged linearly and equidistantly, are fixedly installed on the top of the base plate 1. The hat-shaped support plates 2 are perpendicular to the base plate 1. The hat-shaped support plates 2 have a first arc-shaped mounting opening 3, a second arc-shaped mounting opening 4, and a third arc-shaped mounting opening 5. A top chord steel bar 6 is commonly arranged within each of the first arc-shaped mounting opening 3. A first bottom chord steel bar 7 is commonly arranged within each of the second arc-shaped mounting opening 4. A second bottom chord steel bar 8 is commonly arranged within each of the third arc-shaped mounting opening 5. Web steel bars 9 are fixedly welded between the top chord steel bar 6 and the first bottom chord steel bar 7, and between the top chord steel bar 6 and the second bottom chord steel bar 8. The chord reinforcement 6 bears the upper load and transmits the force to the first lower chord reinforcement 7 and the second lower chord reinforcement 8 through the web reinforcement 9. The first transverse reinforcement plate 10 is fixedly connected between each of the two adjacent cap-shaped support plates 2. The first lower chord reinforcement 7 and the second lower chord reinforcement 8 then distribute the load to the bottom plate 1 and multiple cap-shaped support plates 2. An A-shaped reinforcement 11 is provided between the first transverse reinforcement plate 10 and the bottom plate 1. The upper and lower ends of the A-shaped reinforcement 11 are welded and fixed to the first transverse reinforcement plate 10 and the bottom plate 1, respectively. Several cap-shaped support plates 2 and several A-shaped reinforcement 11 are linearly staggered. Several A-shaped reinforcement 11 are located between two web reinforcement 9, and the two web reinforcement 9 are arranged opposite to each other.

[0029] The A-shaped reinforcement 11 includes a V-shaped reinforcing plate 12 welded and fixed to the lower surface of the first transverse reinforcement plate 10. The V-shaped reinforcing plate 12 is laterally fixed and welded to the two inner surfaces of the second transverse reinforcement plate 13. Through the V-shaped reinforcing plate 12 and the second transverse reinforcement plate 13 in the A-shaped reinforcement 11, the area between the first transverse reinforcement plate 10 and the bottom plate 1 can be reinforced in both diagonal and transverse directions, thereby effectively resisting the lateral deformation of the truss.

[0030] like Figure 3 and Figure 4 As shown, two reinforcing rods 14 are welded and fixed between each of the two adjacent cap-shaped support plates 2. The two reinforcing rods 14 are located on opposite sides of the A-shaped reinforcement member 11. The reinforcing rods 14 further strengthen the connection stability between the adjacent cap-shaped support plates 2 on both sides of the A-shaped reinforcement member 11.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the second arc-shaped mounting opening 4 and the third arc-shaped mounting opening 5 are symmetrically distributed about the central axis of the hat-shaped support plate 2. The first arc-shaped mounting opening 3 is located above the second arc-shaped mounting opening 4 and the third arc-shaped mounting opening 5. The upper chord steel bar 6, the first lower chord steel bar 7 and the second lower chord steel bar 8 are all welded and fixed to the hat-shaped support plate 2. The connection between the components can be ensured by welding.

[0032] The working principle of the above embodiment is as follows: the upper chord steel bar 6 bears the upper load, and the web steel bar 9 transmits the force to the first lower chord steel bar 7 and the second lower chord steel bar 8. The first lower chord steel bar 7 and the second lower chord steel bar 8 then distribute the load to the bottom plate 1 and multiple cap-shaped support plates 2. Through the V-shaped reinforcing plate 12 and the second transverse reinforcing plate 13 in the A-shaped reinforcement member 11, the area between the first transverse reinforcing plate 10 and the bottom plate 1 can be double-reinforced in both diagonal and transverse directions, thereby effectively resisting the lateral deformation of the truss. The first transverse reinforcing plate 10 connects the adjacent cap-shaped support plates 2, which strengthens the longitudinal structural stiffness. The reinforcing rod 14 further strengthens the connection stability between the adjacent cap-shaped support plates 2 on both sides of the A-shaped reinforcement member 11. Through the cooperation of multiple components, a multi-reinforcement structure is formed, which makes the overall stress of the steel truss more reasonable, effectively distributes the load, and greatly improves the compressive, tensile and shear strength of the steel truss, enabling it to withstand greater building loads and achieve higher structural stability.

[0033] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
