Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel beam support device. Background Technology

[0002] With the development of urban construction and the advancement of building technology, large-span buildings have become one of the main directions of building structure development. Steel-reinforced concrete structures give full play to the characteristics of both steel and concrete. Compared with reinforced concrete structures, they have the advantages of strong deformation capacity and good seismic performance; compared with steel structures, they have the characteristics of high structural stiffness and high overall stability.

[0003] Chinese invention patent application publication number CN118498743A discloses a positioning and adjustment support system for H-beams with steel frame and its usage method. This system consists of a plate surface support device and a beam bottom support device. The plate surface device includes a fixed base, rotatable support rods, and a grooved fulcrum adjustment screw; the beam bottom device includes a clip, a bottom adjustment screw, and a long nut. Precise positioning is achieved through screw adjustment, reducing the operating time of tower cranes, effectively limiting the horizontal and vertical displacement of the H-beam, and ensuring it is in the correct stress position. This system fills the gap in the technology of addressing the inability to adjust steel frame beams after installation.

[0004] However, the invention's adjustment mechanism is highly complex and relies on the coordinated operation of the fulcrum adjustment screw, the bottom adjustment screw, and multiple sets of nuts. It requires repeated adjustments to the horizontal and vertical positioning, involves many steps, and is complex, requiring a high level of precision from the operator.

[0005] Chinese Utility Model Patent Publication No. CN211691465U discloses a formwork support device for steel-concrete beams, including side formwork and bottom formwork fixing devices. The bottom formwork is supported by a disc-lock bracket and a support plate; the side formwork includes main joists, secondary joists, and tie bolts, which fix the side formwork by bolts, eliminating the need to drill holes in the steel beam, avoiding strength loss, and resulting in a stable and efficient structure.

[0006] However, this utility model side template requires the sequential installation of secondary keels (closely attached to the template), main keels (outer support), and tie bolts, with each of the three components needing to be positioned and fixed layer by layer. In actual operation, it is necessary to repeatedly adjust the fit between the secondary keels and the template, the perpendicularity between the main keels and the secondary keels, and the bolt holes need to be precisely aligned, which is time-consuming. Therefore, the implementation of this utility model patent depends on the skill of the operators and requires a high degree of precision in their operation.

[0007] The two patents mentioned above respectively solve the technical problems of positioning and adjustment during steel beam construction and avoiding the need for formwork with openings in the steel beams. However, they share the common problem of over-reliance on precise manual operation. In the reality of complex construction site environments and varying worker skill levels, their theoretical advantages may be difficult to fully realize. Therefore, a simple and easy-to-operate steel beam support device is needed to address the technical problems of steel beams being tall, narrow, and prone to tipping due to poor self-stability. Utility Model Content

[0008] To address the shortcomings of existing technologies, the present invention provides a steel beam support device that solves the problem of poor self-stability and easy tilting of steel beams.

[0009] To solve the above problems, the technical solution adopted by this utility model is: a steel beam support device, including a bottom support, a connecting rod, a vertical rod, and a top horizontal rod. The bottom support includes a bottom horizontal rod and a diagonal brace, which are fixedly connected to form an isosceles triangle stable structure. The connecting rod is fixedly connected to the top of the bottom support, and the connecting rod and the bottom horizontal rod are perpendicular in space. The length of the connecting rod is the same as the width of the concrete formwork. The lower end of the vertical rod is fixedly connected to the connecting rod, and the upper end of the vertical rod is fixedly connected to the top horizontal rod. The net spacing between the vertical rods is equal to the flange width of the steel beam. The top horizontal rod is flush with the upper surface of the formwork and is fixed to the formwork. The top horizontal rod and the connecting rod belong to the same vertical plane and are parallel.

[0010] Furthermore, transverse connecting rods are fixedly connected between the bottom crossbars. These transverse connecting rods are on the same plane and perpendicular to each other, forming a grid-like support system. This enhances the overall anti-overturning capability.

[0011] Furthermore, the bottom support also includes a vertical strut, which is positioned at the midpoint of the bottom horizontal bar, dividing the isosceles triangle stable structure into two symmetrical triangles. The vertical strut is fixedly connected to the bottom support.

[0012] Furthermore, at least two bottom supports are provided along the cross-sectional direction of the beam.

[0013] Furthermore, at least two support devices should be used side by side along the longitudinal direction of the beam.

[0014] Furthermore, the material of the support device is steel bars or structural steel.

[0015] The beneficial effects of this solution are: 1. The triangular stable structure design of the bottom support effectively improves the bottom's anti-overturning capacity; 2. The layout of the vertical bar spacing matching the flanges of the steel beam achieves directional support for both sides (key stress points) of the upper and lower flanges of the steel beam, forming a three-dimensional stable frame; 3. The design of the connecting rods being the same width as the template not only allows the connecting rods to act as internal supports, but also, in conjunction with the top horizontal bars fixed on the template, allows the connecting rods and the top horizontal bars to form a double constraint, effectively suppressing displacement deviations during construction; 4. Constructing a three-dimensional stable system of "bottom triangular support → vertical bar positioning → top template locking" ensures that the steel beam is fixed at the design elevation; 5. This device has a simple structure, is easy to operate, and requires relatively low skill levels from workers. Attached Figure Description

Detailed Implementation

[0023] The following detailed description illustrates the specific implementation method:

[0024] Example 1

[0025] As attached Figure 1 , 3As shown in Figure 5: A steel beam 5 support device includes a bottom support 1, a connecting rod 2, a vertical rod 3, and a top horizontal rod 4. The bottom support 1 includes a bottom horizontal rod 11 and two diagonal braces 12. The bottom horizontal rod 11 and the two diagonal braces 12 are welded and fixed to form an isosceles triangle stable structure. The connecting rod 2 is welded and fixed to the top of the bottom support 1, and the connecting rod 2 and the bottom horizontal rod 11 are perpendicular in space. The length of the connecting rod 2 is the same as the width of the concrete formwork 6, so that the connecting rod 2 plays the role of internal support. The lower end of the vertical rod 3 is welded and fixed to the connecting rod 2, and the upper end of the vertical rod 3 is welded and fixed to the top horizontal rod 4. The net spacing of the vertical rods 3 is equal to the flange width of the steel beam 5 to ensure that the flange of the steel beam 5 can be embedded between the vertical rods 3 and stably limited. The top horizontal rod 4 is flush with the upper surface of the formwork 6 and is fixed to the formwork 6 by clips. The top horizontal rod 4 and the connecting rod 2 belong to the same vertical plane and are parallel.

[0026] The supporting device uses steel bars or structural steel commonly found on construction sites.

[0027] During construction, firstly, weld the bottom horizontal bar 11 and the diagonal brace 12 to form an isosceles triangle bottom support 1. Distribute at least two bottom supports 1 evenly along the beam cross-section. Then, determine the length of the connecting rod 2 based on the width of the formwork 6, and weld the connecting rod 2 to the upper end of the bottom support 1. Next, weld the vertical bars 3, ensuring their spacing matches the flange of the steel beam 5. Finally, weld the top horizontal bar 4 to the vertical bar 3 and fix the top horizontal bar 4 to the formwork 6 using clips. At least two support devices should be used to fix the same section of the steel beam 5.

[0028] Example 2

[0029] As attached Figure 2 , 4 As shown in Figure 6, the support device structure differs from that in Embodiment 1 in that a transverse connecting rod 13 is welded and fixed between the bottom crossbars 11. The transverse connecting rod 13 and the bottom crossbars 11 are on the same plane and perpendicular to each other, forming a grid support system. The bottom support 1 also includes a vertical support rod 14, which is located at the midpoint of the bottom crossbars 11, dividing the isosceles triangle stable structure into two symmetrical triangles. The vertical support rod 14 is welded and fixed to the bottom support 1.

[0030] By adding a horizontal connecting rod 13 and a vertical strut to the bottom support 1, the stability of the bottom support 1 is enhanced, and the overall anti-overturning ability is improved.
