Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure supporting frame. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. It has a light weight, simple construction, high degree of industrialization, and can be produced with a high degree of mechanization. Therefore, steel structure support frames are widely used in large factories, venues, super high-rise buildings and other fields.

[0003] Flat steel refers to steel with a rectangular cross section and slightly blunt edges. Flat steel can be finished steel, or it can be used as a blank for welded pipes and thin plate blanks for rolled thin plates. Flat steel as a finished product can be used to make hoops, tools and mechanical parts.

[0004] The utility model with application number 202222192883.3 discloses an earthquake-resistant steel structure support frame, by respectively providing connecting blocks at the top ends of the supporting steel columns, when the supporting steel columns are combined and connected with the transverse steel columns in use, the connecting sleeves fixedly connected to one side of the connecting block are respectively sleeved on both sides of the transverse steel columns, and then the connecting sleeves fixedly connected to the bottom ends of the connecting blocks are respectively sleeved on the top ends of the supporting steel columns, and the connecting sleeves and the transverse steel columns of the supporting steel columns are respectively connected and fixed through the connecting holes, thereby achieving the effect of convenient, fast and stable assembly and connection between the components of the support frame, and by respectively fixing stable slots at the middle positions at the top ends of the fixing seats, when the steel structure support frame is installed, the stable plugs fixedly connected to the bottom ends of the supporting steel columns are respectively inserted into the fixed The inside of the connected stable slot, and the stability of the plug-in is improved by the stable pad. At the same time, the plug-in bolts fixedly connected to the two sides and both ends of the stable plug-in block are respectively inserted into the inside of the reserved slot, and then the locking nuts are respectively sleeved on the outside of the plug-in bolts and tightened, so that the stable plug-in block can be firmly inserted into the inside of the stable slot, thereby achieving the effect of convenient, fast and stable pre-stabilization installation of the support frame. The top of one side of the supporting steel column and the two sides of the bottom end of the horizontal steel column are respectively fixedly connected with the fixing sleeves. When in use, the "U"-shaped fixing sleeves are respectively fixedly connected to the top of one side of the supporting steel column and the two sides of the bottom end of the horizontal steel column, and the reinforcing plates are respectively fixedly connected between one side and one end of the fixing sleeve, and the reinforcing plates are inclined at 45°. The structural stability of the support frame can be effectively improved by the reinforcing plates, and the seismic resistance can be improved.

[0005] However, the above-mentioned earthquake-resistant steel structure support frame needs to lift the transverse steel columns to above the supporting steel columns during assembly, which makes the disassembly and assembly efficiency of the support frame low. The above-mentioned earthquake-resistant steel structure support frame uses an inclined and fixed reinforcement plate rigid structure to improve the earthquake resistance, but the lack of an elastic buffer structure makes the rigid support's earthquake resistance effect limited. Therefore, the utility model proposes a steel structure support frame to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a steel structure support frame, including a base 1, an articulated deployment mechanism, a reinforced support mechanism and an anti-seismic mechanism. The articulated deployment mechanism includes a vertical support frame 2, a first articulated seat 3, a transverse support frame 4, a slide rail 5 and a slider 6. The base 1 is provided with two groups. The base 1 is provided with a vertical support frame 2, a transverse support frame 4 is provided above the vertical support frame 2, and a first articulated seat 3 is articulated at both ends of the transverse support frame 4. The first articulated seat 3 on one side is fixedly connected to the vertical support frame 2 on one side, and a slide rail 5 is fixed on the vertical support frame 2 on the other side. The slide rail 5 A slider 6 is provided on the upper slide, and the slider 6 is fixedly connected to the first hinge seat 3 on the other side. A reinforcing support mechanism is symmetrically provided below the transverse support frame 4, and an anti-seismic mechanism is provided on the reinforcing support mechanism. When the support frame is installed, the vertical support frame 2 is pulled to both sides to make the transverse support frame 4 hinged and unfolded. As the transverse support frame 4 unfolds, the slider 6 is driven to slide upward along the slide rail 5 to the upper end of the vertical support frame 2 on one side, and then the bolts are fixed to complete the unfolding and installation, which solves the problem of lifting the transverse steel column to the top of the supporting steel column when assembling the steel structure support frame, and effectively improves the disassembly and assembly efficiency.

[0020] A limit plate 7 is fixedly provided on the upper end of the vertical support frame 2. Square holes 8 are provided at intervals on the vertical support frame 2 and the horizontal support frame 4. The limit plate 7 limits the stroke of the slider 6 to prevent the slider 6 from slipping. The square hole 8 reduces the weight of the vertical support frame 2 and the horizontal support frame 4, making it convenient for the support frame to be quickly transported and erected.

[0021] The strengthening support mechanism includes a strengthening support frame 10, a second hinge seat 9, and a first bolt hole 11. The strengthening support frame 10 is symmetrically arranged below the transverse support frame 4. The second hinge seats 9 are symmetrically hinged at both ends of the strengthening support frame 10. First bolt holes 11 are provided on both sides below the transverse support frame 4 and in the middle of the inner side of the vertical support frame 2. An anti-seismic mechanism is arranged in the middle of the strengthening support frame 10. The second hinge seat 9 is bolted to the transverse support frame 4 and the vertical support frame 2 through the first bolt hole 11. When the transverse support frame 4 is unfolded, the strengthening support frame 10 is hingedly rotated to form a triangular support with the vertical support frame 2 and the transverse support frame 4, and then is bolted through the first bolt hole 11, thereby improving the stability of the support frame when unfolded.

[0022] The anti-seismic mechanism includes a rotating seat 12, an anti-seismic spring 13, a locking seat 14 and a second bolt hole 15. A rotating seat 12 is rotatably provided on the middle bearing of the reinforced support frame 10, and an anti-seismic spring 13 is fixedly provided on the rotating seat 12. A locking seat 14 is fixedly provided on the upper end of the anti-seismic spring 13. Second bolt holes 15 are symmetrically opened on both sides below the transverse support frame 4, and the locking seat 14 is bolted to the transverse support frame 4 through the second bolt holes 15. When the reinforced support frame 10 is fixed, the anti-seismic spring 13 is rotated to make the upper end locking seat 14 bolted to the transverse support frame 4 through the second bolt holes 15. The anti-seismic spring 13 is used to elastically buffer and resolve the vibration generated during use, thereby solving the problem of limited anti-seismic effect of the rigid connection of the inclined fixed reinforcement plate lacking a buffer structure.

[0023] When the steel structure support frame is unfolded and built, the vertical support frame is pulled to both sides so that the transverse support frame is hinged and rotated to unfold through the first hinge seat, and one side of the transverse support frame rotates upward, and the slider slides upward along the slide rail to move below the limit plate, so that the transverse support frame is horizontally unfolded, and the reinforced support frame is pushed to be hinged and rotated through the second hinge seat to tilt outward, and the second hinge seat at the lower end is bolted and fixed with the vertical support frame through the first bolt hole, and the second hinge seat at the upper end is bolted and fixed with the transverse support frame through the first bolt hole. Then, the anti-seismic spring is pushed to rotate in cooperation with the rotating seat, so that the locking seat is rotated to the position of the second bolt hole and then bolted. When encountering vibration, the anti-seismic spring deforms to absorb vibration, and the bolt fixation of the first bolt hole and the second bolt hole is released during disassembly, pushing the vertical support frame to move toward each other, so that the transverse support frame is hinged and folded to reduce the footprint.

[0024] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
