Description

Technical Field

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

[0002] A wide variety of steel structural components are used in various construction projects, including bridges, subways, and buildings. Among them, steel support structures, as a common component, play a crucial role in providing temporary or permanent support to other structures during the construction process.

[0003] During the construction of the main beams and columns of a building, the prestress of the existing steel supports is usually applied all at once during construction, which makes it difficult to adjust according to the actual situation during use. The accuracy of prestress application is difficult to guarantee. For beams and columns with irregular load distribution, the adaptability is poor and it is difficult to meet the diverse architectural design requirements.

[0004] After the beams and columns of different models are supported, they need to be fixed to prevent them from shifting under stress and causing safety hazards. Existing steel supports are generally connected by high-strength bolts, welding, anchor plates and anchor bolts. These connection methods are complicated to operate, increase construction time, and are inconvenient to disassemble if disassembly is required later.

[0005] In view of this, the present invention is proposed to solve the above-mentioned technical problems. Utility Model Content

[0018] Furthermore, pressure plates are provided on multiple pads near the fixing component, and the fixing component is fixedly mounted on the pressure plates.

[0019] Furthermore, the fixing component includes a lower fixing ring disposed on the pressure plate;

[0020] An upper fixing ring is coaxially disposed above the lower fixing ring;

Detailed Implementation

[0040] The specific embodiments of this utility model will be described in further detail with reference to the accompanying drawings.

[0041] See Figures 1 to 6 As shown in the embodiment of this application, a steel support structure is provided, including: a main support frame 1, an auxiliary support truss assembly, multiple prestressing adjustment components, and a fixing component 5. The main support frame 1 includes four vertically arranged first square tube columns 11. The upper and lower ends of two adjacent first square tube columns 11 are fixedly connected by second square tube columns 12 to form the main support frame 1. The auxiliary support truss assembly includes multiple triangular outer trusses 2 and multiple triangular inner trusses 3. The multiple triangular outer trusses 2 are respectively arranged on multiple outer surfaces of the main support frame 1. The multiple triangular inner trusses 3 are respectively arranged at the connection between the first square tube columns 11 and the second square tube columns 12. The multiple prestressing adjustment components are respectively arranged inside the multiple first square tube columns 11 and the multiple second square tube columns 12. The fixing component 5 is arranged on the main support frame 1. Under normal use, the multiple first square tube columns 11 and the multiple second square tube columns 12 bear the main vertical and horizontal loads. The multiple triangular outer trusses 2 enhance the overall stability and lateral resistance of the steel support structure. The multiple triangular inner trusses 3 are used to improve the stability of the main support frame 1 structure.

[0042] In the above scheme, four first square tube columns 11 are connected to multiple second square tube columns 12 to form a stable frame structure, providing stable support for the beams and columns. The prestress adjustment components installed in the first square tube columns 11 and the second square tube columns 12 facilitate the workers to adjust the prestress of the steel supports at any time during construction, thereby adapting to beams and columns with irregular load distribution and construction environment. The fixing components 5 replace the existing connection methods of high-strength bolts, welding, anchor plates and anchor bolts, thereby reducing the difficulty of fixing and positioning beams and columns, improving construction efficiency, and also facilitating the disassembly of steel supports.

[0043] See some possible implementations. Figure 4 and Figure 5 As shown, both ends of the first square column 11 are provided with pads 6. The pads 6 at the lower end of the first square column 11 can be fixed to the ground or building foundation by bolts. The prestressing adjustment component includes prestressed steel strand bundles 7 installed in the first square column 11 or the second square column 12. The two ends of the prestressed steel strand bundles 7 in the first square column 11 are respectively fixed to the two pads 6. The two ends of the prestressed steel strand bundles 7 in the second square column 12 are respectively fixed to the outer wall of the adjacent first square column 11. The inner wall of the first square column 11 or the second square column 12 is provided with tension members 8. The output end of the tension member 8 is connected to the corresponding prestressed steel strand bundle 7.

[0044] It should be noted that the tensioning component 8 is an electric tensioner or a bolt with a U-shaped clamp. When the steel support structure is permanently supported, the tensioning component 8 is a bolt with a U-shaped clamp. In this case, the U-shaped clamp is sleeved on the prestressed steel strand bundle 7. Threaded bolts are provided on the outer wall of the first square tube 11 or the second square tube 12. One end of the bolt penetrates the outer wall of the first square tube 11 or the second square tube 12 and is located inside the first square tube 11 or the second square tube 12. The end of the bolt located inside the first square tube 11 or the second square tube 12 is movably connected to the U-shaped clamp. When the vertical or horizontal prestress of the steel support needs to be adjusted, the bolts on the first square tube column 11 or the second square tube column 12 are rotated. The end of the bolt located inside the first square tube column 11 or the second square tube column 12 drives the U-shaped clamp to extend or retract. The U-shaped clamp stretches or relaxes the prestressed steel strand bundle 7, thereby adjusting the internal prestress of the first square tube column 11 or the second square tube column 12. This allows the steel support structure to be in a more favorable stress state under load, and the prestress can be adjusted in real time according to the deformation and stress of the steel support structure, thereby effectively controlling the displacement and internal force distribution of the steel support structure. When the steel support structure is temporarily supported, the tensioning member 8 is an electric tensioner. The electric tensioner is electrically connected to an external power source. When the vertical or horizontal prestress of the steel support needs to be adjusted, the electric tensioner is activated. The output end of the electric tensioner drives the prestressed steel strand bundle 7 to stretch or relax, thereby adjusting the internal prestress of the first square tube column 11 or the second square tube column 12.

[0045] See some possible implementations. Figure 6 As shown, both the first square tube column 11 and the second square tube column 12 have reinforcing baffles 9 along their length on their inner walls. The reinforcing baffles 9 are used to improve the load-bearing capacity and stability of the first square tube column 11 and the second square tube column 12.

[0046] See some possible implementations. Figure 1As shown, multiple pads 6 near the fixed component 5 are provided with pressure plates 4. The fixed component 5 is fixedly installed on the pressure plates 4. The pressure plates 4 are used to increase the bearing area of ​​the main support frame 1, thereby improving the bearing capacity and stability of the main support frame 1.

[0047] See some possible implementations. Figure 2 As shown, the fixing component 5 includes a lower fixing ring 51 disposed on the pressure plate 4, and an upper fixing ring 52 coaxially disposed above the lower fixing ring 51. The lower fixing ring 51 and the upper fixing ring 52 have the same structure and size. Multiple supports 53 are evenly disposed on the lower fixing ring 51 along its circumference, and each support 53 is provided with an elastic element.

[0048] The elastic element includes a horizontal support shaft 54 ​​fixedly mounted on the support 53. A rotatable pressure rod 55 is mounted on the horizontal support shaft 54. The pressure rod 55 is located at the lower end of the upper fixed ring 52. A spiral spring 59 is sleeved on the horizontal support shaft 54 ​​on both sides of the pressure rod 55. One end of the spiral spring 59 is fixed on the horizontal support shaft 54, and the other end of the spiral spring 59 is located at the bottom of the pressure rod 55.

[0049] In the above scheme, the pressure rod 55 is located at the lower end of the upper fixing ring 52, and under the action of the spiral spring 59, the upper surface of the pressure rod 55 abuts against the bottom edge of the upper fixing ring 52. When it is necessary to fix the beam and column, the upper fixing ring 52 is controlled to move down. The downward movement of the upper fixing ring 52 drives multiple pressure rods 55 to rotate clockwise synchronously, so that multiple pressure rods 55 abut against the outer wall of the beam and column at the same time, thereby completing the fixation of the beam and column.

[0050] See some possible implementations. Figure 2 As shown, multiple pressing members are evenly arranged between the lower fixing ring 51 and the upper fixing ring 52. The pressing members include a vertical rod 57 arranged on the lower fixing ring 51. The upper end of the vertical rod 57 is provided with an external thread. The upper end of the vertical rod 57 passes through the upper fixing ring 52, and a nut 56 that mates with the external thread is provided at the upper end of the vertical rod 57. The nut 56 is located on the side of the upper fixing ring 52 away from the lower fixing ring 51. The nut 56 is in contact with the upper surface of the upper fixing ring 52. A spring 58 is sleeved on the vertical rod 57 between the lower fixing ring 51 and the upper fixing ring 52.

[0051] In the above scheme, when providing permanent support for the beam and column, the upper fixing ring 52 is manually moved downward in order to save costs. When fixing the beam and column, the two symmetrical nuts 56 are rotated at the same time, so that the nuts 56 rotate spirally on the external thread and move downward, which drives the upper fixing ring 52 to move downward. The upper fixing ring 52 moves downward to compress the spring 58. At the same time, the downward movement of the upper fixing ring 52 drives multiple pressure rods 55 to rotate clockwise, so that multiple pressure rods 55 simultaneously abut against the outer wall of the beam and column, thereby fixing the beam and column.

[0052] In some possible implementations, the pressing component also includes a plurality of hydraulic rods (not shown in the figure) disposed on the lower fixing ring 51. The plurality of hydraulic rods are evenly arranged along the circumferential direction of the lower fixing ring 51, and the output end of the hydraulic rods is fixedly disposed at the bottom of the upper fixing ring 52.

[0053] In the above scheme, when providing temporary support for beams and columns, in order to improve the efficiency of fixing and supporting, hydraulic rods are used to drive the upper fixing ring 52 to move downward. At this time, it is only necessary to control multiple hydraulic rods to start synchronously, so that the output ends of multiple hydraulic rods retract, thereby driving the upper fixing ring 52 to move downward. When the upper fixing ring 52 moves downward, the lower surface of the upper fixing ring 52 compresses the spring 58. At the same time, the downward movement of the upper fixing ring 52 drives multiple pressure rods 55 to rotate clockwise, so that multiple pressure rods 55 simultaneously abut against the outer wall of the beam and column, thereby completing the fixing of the beam and column.

[0054] This specific embodiment is merely an explanation of the utility model and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection of this utility model.
