AI Technical Summary
Steel structures in factory buildings are prone to deformation after being subjected to various loads, which leads to a decrease in rigidity. In particular, the stress distribution in the beams is uneven, affecting the structural stability and vibration resistance.
A tensioning structure using prestressed steel tie rods and cables is adopted. By installing prestressed steel tie rods and cables on the local second-floor beams, the axial tensile force is transferred to the rigid frame columns through the tension and fixing effect of the prestressed steel tie rods, reducing the bending moment caused by external loads, enhancing the bending resistance of the local second-floor beams, and avoiding resonance through the tensioning of the steel cables.
It effectively reduced the deformation and vibration of the steel structure of the factory building, improved the stability and vibration resistance of the structure, reduced fatigue damage, and enhanced the overall rigidity of the steel structure.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure building technology, and in particular to a steel structure for factory buildings that maintains structural rigidity through tensioning. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. With advantages such as easy installation and short construction period, steel structure factory buildings have become one of the mainstream forms of factory building construction.
[0003] In actual use, the following shortcomings were found in the steel structure of the factory building:
[0004] Because steel structures in factory buildings typically have large spans and need to withstand various loads, such as self-weight, equipment weight, wind load, and snow load, steel structures in factory buildings are prone to deformation caused by external loads (such as equipment weight and wind load) after being put into use. Large-span structures lead to uneven stress distribution in steel structures, mainly concentrated on steel beams. Beams are prone to deformation due to sagging or vibration, resulting in a decrease in the rigidity of the entire steel structure of the factory building.
[0005] Therefore, this application provides a tensioned steel structure for factory buildings to maintain structural rigidity in order to meet the requirements. Utility Model Content
[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a factory steel structure that maintains structural rigidity by tensioning.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A steel structure for factory buildings, designed to maintain structural rigidity through tensioning, includes: rigid frame columns, partially double-layer beams, partially double-layer columns, corbels, rigid frame beams, fixed seats, prestressed steel tie rods, supports, anchor bolts, steel cables, and connecting seats. Partial double-layer beams are installed at the inner middle of the rigid frame columns. Several sets of partially double-layer columns are installed at the bottom of the partially double-layer beams on the sides of the rigid frame columns. Corbels are welded to the upper ends of the sides of the rigid frame columns. Rigid frame beams are installed at the top of the rigid frame columns. Fixed seats are installed at the upper middle of the partially double-layer beams. The surface of the fixed seats is provided with… The frame has a placement groove, and the fixing seat has an installation hole at the outer end of the side of the placement groove. A prestressed steel tie rod is installed in the placement groove of the fixing seat. A first anchoring plate is installed at one end of the prestressed steel tie rod, and a second anchoring plate is installed at the other end of the prestressed steel tie rod. A damper is installed in the middle section of the prestressed steel tie rod, and a bracket is installed at the outer end of the prestressed steel tie rod. An anchor rod is installed inside the bracket, and a steel cable is bound to the other end of the anchor rod. A connecting seat is welded to the upper end of the rigid frame column.
[0009] Preferably, the fixing seat is rectangular, and the surface of the fixing seat is provided with four sets of mounting holes. The fixing seat is fixed to the transverse frame beam of the partial second-layer beam by bolts.
[0010] Preferably, two sets of prestressed steel tie rods are installed on the upper end of the fixed base, and the second anchoring plates of the two sets of prestressed steel tie rods are respectively vertically installed in the placement grooves on the left and right sides of the fixed base.
[0011] Preferably, the prestressed steel tie rod extends vertically through the bracket to the upper end of the bracket, and a first anchoring plate is installed on the upper surface of the bracket.
[0012] Preferably, the bracket is rectangular and is parallel to the fixed base via a prestressed steel tie rod.
[0013] Preferably, the anchor rods are provided in two sets, and the two sets of anchor rods are respectively installed on the left and right sides of the upper end of the bracket, and the anchor rods are located at the outer side of the prestressed steel tie rod.
[0014] Preferably, the connecting seat is L-shaped and is installed at the upper corner where the corbel connects to the rigid frame column. The other end of the steel cable is inclined upward and straightened, passing through the rigid frame column and connecting to the connecting seat.
[0015] Preferably, the steel cable is equidistant from the end angles of the rigid frame column and the partial second-floor beam, forming two sets of triangles.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, two sets of prestressed steel tie rods are installed at the upper middle of the second-floor beam. A bracket is installed at the upper end of the prestressed steel tie rod, and an anchor rod for binding steel cables is installed at the upper side of the bracket. The other end of the steel cable is inclined upward and straightened through the rigid frame column and connected to the connecting seat. The steel cable is tensioned to a predetermined tension value using tensioning equipment, which converts more of the load into tension and reduces the compression area. The tensioning structure of the steel cable usually has a higher natural frequency, which can avoid resonance with the operating frequency of the equipment in the plant, thereby reducing structural vibration, reducing fatigue damage, and improving structural stability.
[0018] In the above scheme, prestressed steel tie rods are arranged at the support ends of the steel structure. These prestressed steel tie rods can support the steel cables and can be supported at the upper middle of the local second-floor beam. Through tension and fixation, they have a certain load-bearing capacity and deformation capacity. Due to the combined effect of prestress and the new external load, axial tensile force is generated in the tie rod. This force is eccentrically transmitted to the rigid frame column through the steel cable anchored at the end of the rod, generating eccentric compression in the rigid frame column. This action overcomes part of the bending moment generated by the external load, reduces the effect of the external load, and can compensate for the deformation of the local second-floor beam caused by vibration, thereby improving the bending resistance of the local second-floor beam.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention discloses a steel structure for a factory building that maintains structural rigidity through tensioning. An embodiment of the present invention includes: a rigid frame column 1, a partially double-layer beam 2, partially double-layer columns 3, corbels 4, a rigid frame beam 5, a fixing seat 6, prestressed steel tie rods 7, supports 8, anchor bolts 9, steel cables 10, and connecting seats 11. A partially double-layer beam 2 is installed at the middle of the inner side of the rigid frame column 1. Several sets of partially double-layer columns 3 are installed at the bottom of the partially double-layer beam 2 on the side of the rigid frame column 1. Corbels 4 are welded to the upper end of the side of the rigid frame column 1. A rigid frame beam 5 is installed at the top of the rigid frame column 1. A fixing seat 6 is installed at the middle of the upper end of the partially double-layer beam 2. The surface is provided with a placement groove 601. The fixing seat 6 is provided with an installation hole 602 at the outer end of the side of the placement groove 601. A prestressed steel tie rod 7 is installed in the placement groove 601 of the fixing seat 6. A first anchoring plate 701 is installed at one end of the tie rod of the prestressed steel tie rod 7, and a second anchoring plate 702 is installed at the other end of the tie rod of the prestressed steel tie rod 7. A damper 703 is installed in the middle section of the tie rod of the prestressed steel tie rod 7. A bracket 8 is installed at the outer end of the tie rod of the prestressed steel tie rod 7. An anchor rod 9 is installed inside the bracket 8. A steel cable 10 is tied to the other end of the anchor rod 9. A connecting seat 11 is welded at the upper end of the rigid frame column 1.
[0031] In this embodiment, the fixing seat 6 is rectangular in shape, and four sets of mounting holes 602 are provided on the surface of the fixing seat 6. The fixing seat 6 is fixed to the transverse frame beam of the partial second-layer beam 2 by bolts. The four corners of the fixing seat 6 are respectively fixed to the transverse frame beam of the partial second-layer beam 2, so that the stability of the installation between the fixing seat 6 and the partial second-layer beam 2 is guaranteed.
[0032] In this embodiment, two sets of prestressed steel tie rods 7 are installed on the upper end of the fixed base 6, and the second anchoring plates 702 of the two sets of prestressed steel tie rods 7 are respectively vertically installed in the placement grooves 601 on the left and right sides of the fixed base 6. The prestressed steel tie rods 7 can support the bracket 8.
[0033] In this embodiment, the prestressed steel tie rod 7 extends vertically through the bracket 8 to the upper end of the bracket 8, and the upper surface of the bracket 8 is equipped with a first anchoring plate 701.
[0034] In this embodiment, the support 8 is rectangular in shape and is parallel to the fixed seat 6 via a prestressed steel tie rod 7. This can compensate for the local deformation of the second-layer beam 2 caused by vibration. The prestressed steel tie rod 7 can be supported at the middle of the upper end of the local second-layer beam 2. Through tension and fixation, it has a certain load-bearing capacity and deformation capacity. Due to the combined effect of prestress and the new external load, an axial tensile force is generated in the tie rod. This force is eccentrically transmitted to the rigid frame column 1 through the steel cable 10 anchored at the end of the rod, generating an eccentric compression effect in the rigid frame column 1. This effect overcomes part of the bending moment generated by the external load, reduces the effect of the external load, and thus improves the bending resistance of the local second-layer beam 2.
[0035] In this embodiment, two sets of anchor rods 9 are provided. The two sets of anchor rods 9 are respectively installed on the left and right sides of the upper end of the support 8, and the anchor rods 9 are located at the outer side of the prestressed steel tie rod 7. As the tie rod and support 8 transmit the pressure to the rigid frame column 1 to both sides through the anchor rods 9 and steel cables 10, the pressure is relieved and controlled, and the shear bearing capacity of the inclined section is also improved, which can improve the vibration resistance of the steel structure workshop.
[0036] In this embodiment, the connecting seat 11 is L-shaped and is installed at the upper corner where the corbel 4 connects to the rigid frame column 1. The other end of the steel cable 10 is pulled straight upward and passes through the rigid frame column 1 to connect with the connecting seat 11. The L-shaped connecting seat 11 is installed at the end corner, which makes it more stable under force.
[0037] In this embodiment, the steel cable 10 is equidistantly separated from the end angles of the rigid frame column 1 and the partial second-layer beam 2 into two sets of triangles. The steel cable 10 is tensioned to a predetermined tension value using a tensioning device, which converts more of the load into tension and reduces the pressure area. The tensioning structure of the steel cable 10 usually has a higher natural frequency, which can avoid resonance with the operating frequency of the equipment in the factory and reduce fatigue damage.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
