Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology in building construction, specifically a large H-shaped steel beam stacking anti-overturning structure. Background Technology

[0002] Steel structures are increasingly being used in modern buildings, especially in public buildings and factories, where the spans and beam dimensions are often quite large. The larger the height-to-width ratio of an H-beam, the more prone the beam is to overturning, posing a significant safety hazard to on-site construction workers.

[0003] Common anti-tipping measures for large H-beams involve welding reinforcing bars or angle steel to the upper flanges of the H-beams, thus welding multiple H-beams together as a single unit. For independent H-beams, diagonal bracing is welded to the upper flanges of angle steel or I-beams as an anti-tipping measure. However, these measures have the following drawbacks: 1) Welding to the upper flanges of the H-beams damages the beam structure and surface coating, requiring rework and repair later, leading to potential quality issues and cost waste. 2) On-site welding involves hot work, which is cumbersome and increases safety hazards. 3) The anti-tipping measures are at their most vulnerable during welding and dismantling for hoisting purposes, as they are not yet fully formed or are being removed. Utility Model Content

[0004] Based on the above technical problems, this utility model provides a stacking anti-tipping structure for large H-beams. It solves the problem of inconvenient installation and dismantling of traditional anti-tipping measures for large H-beams, reduces safety hazards during implementation, eliminates damage to the steel structure coating caused by extensive welding on the steel beam surface, and avoids economic waste due to rework and repairs. The purpose of this utility model is achieved through the following technical solution: A large H-beam stacking anti-overturning structure includes two sets of anti-overturning components symmetrically resting on both sides of the web of the H-beam. Each set of anti-overturning components includes multiple individual steel frames arranged parallel to the span of the H-beam and connecting rods connecting the individual steel frames. Each individual steel frame consists of two right-angled sides and one hypotenuse. The vertical right-angled side fits into the web of the H-beam, and the bottom right-angled side has a tongue and groove joint on the side closest to the right angle that fits into the lower flange of the H-beam. Bolt holes are provided at the same height at both ends of the hypotenuse. The connecting rod has one bolt hole at fixed intervals. Each set of anti-overturning components has one connecting rod at the top and one at the bottom. Bolts are passed through the connecting rods and the bolt holes on the hypotenuse and tightened to connect the individual steel frames into a whole.

[0005] Further optimization involves welding the individual steel frame from angle steel.

[0006] Furthermore, the connecting rod is made of angle steel.

[0007] Furthermore, the height of the vertical right-angled side of the single steel frame is the same as the height of the web of the H-beam.

[0008] Furthermore, the length of the bottom right-angled side of the single steel frame is 0.8 times the height of the web of the H-beam.

[0009] Furthermore, the fixed spacing is no greater than 2m.

[0010] Furthermore, each overturning assembly contains no fewer than three parallel-arranged individual steel frames.

[0011] Advantages and beneficial effects of this utility model: The anti-tipping components in this invention can be pre-welded and directly installed in place, with bolts used for connection, which is convenient and quick, greatly reducing the risk of H-beam overturning. It also avoids on-site welding and hot work, further reducing on-site safety hazards. Furthermore, it avoids directly welding anti-tipping measures onto the H-beam, protecting the integrity of the H-beam structure and surface coating, reducing quality risks and repair costs.

[0015] Example 1: like Figure 1 , 2 As shown, a large H-beam stacking anti-overturning structure includes two sets of anti-overturning components symmetrically resting on both sides of the web of the H-beam 1. Each set of anti-overturning components includes multiple individual steel frames 2 arranged parallel to each other along the span of the H-beam 1, and connecting rods 3 connecting each individual steel frame 2; as shown Figure 3As shown, the single steel frame 2 consists of two right-angled sides and one hypotenuse. The vertical right-angled sides are fitted with the web of the H-beam 1, and the bottom right-angled side has a tongue and groove joint 5 on the side closest to the right angle that fits into the lower flange of the H-beam 1. Figure 4 As shown, bolt holes are provided at the same height at both the top and bottom ends of the inclined side; as Figure 5 As shown, the connecting rod 3 has one bolt hole at fixed intervals, which is consistent with the spacing between two adjacent individual steel frames 2. Each anti-tipping assembly has one connecting rod 3 at the top and one at the bottom. Bolts 4 are passed through the bolt holes on the connecting rod 3 and the inclined side and tightened to connect the individual steel frames 2 into a whole. The upper and lower connecting rods 3 are both horizontal. There are no fewer than three parallel individual steel frames 2 in each anti-tipping assembly.

[0016] In this embodiment, the single steel frame 2 is welded from L50*3mm angle steel. The connecting rod 3 is also made of L50*3mm angle steel. The height of the vertical right-angle side of the single steel frame 2 is the same as the height of the web of the H-beam 1. The length of the bottom right-angle side of the single steel frame 2 is 0.8 times the height of the web of the H-beam 1. The tongue and groove joint 5 is 80mm high and its length is the flange width of the H-beam 1. One bolt hole is made at each end of the single steel frame 200mm away. One bolt hole is made on the connecting rod 3 every 1m. During installation, the single steel frames 2 are arranged along the span of the H-beam 1 on both sides at 1m intervals.

[0017] Working principle: Individual steel frames 2 are arranged at certain intervals along the span of the H-beam 1 to both sides, and lean against the web of the H-beam 1 to serve as anti-overturning supports. Connecting rods 3 are used to connect the individual steel frames 2 into a whole to prevent individual steel frames 2 from tilting or deforming due to uneven stress. Tongue and groove joints 5 are provided at the front end of the individual steel frames 2 to prevent the lower flange of the H-beam 1 from causing the individual steel frames 2 to be placed unevenly or unable to lean against the H-beam 1.

[0018] This invention reduces the incidence of safety hazards such as H-beam overturning and welding fires, while also accelerating construction speed. It eliminates the need to directly weld anti-overturning measures onto the H-beams, increases the protection of the finished H-beams, and reduces rework and repair costs.

[0019] Finally, it should be noted that the above is only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model.
