Description

Technical Field

[0001] This utility model relates to the technical field of beam fixing equipment, and in particular to an I-beam beam fixing device. Background Technology

[0002] In building construction, bridge construction, and the erection of various industrial structures, I-beam supports are widely used to support and transfer gravity loads. However, some problems exist in the existing technology that urgently need to be addressed. Because the beam base needs to be installed on the I-beam, and the bolts are not evenly distributed, bolts on one side may be closer to the upright beam than on the other. In actual working conditions, although this uneven bolt distribution may superficially appear to result in the same fixing force on both sides, the stress at the contact point between the I-beam and the upright beam will differ due to the different supporting forces of the upright beam and the different points of force application of the fasteners. Therefore, when the I-beam supports the beam base, the side farther from the upright beam is more prone to damage. As part of the overall structure, widespread damage to this area will inevitably lead to safety accidents.

[0003] Chinese patent document 202020504607 discloses an I-beam fixing device. This device uses insert steel plates, a first inclined steel plate, and a second inclined steel plate, all positioned in slots on the left and right sides of the I-beam, to ensure stable left-right fixing. Furthermore, by providing socketing protrusions with socketing grooves on their surfaces to accommodate the sides of the I-beam, it ensures stable vertical fixing. Each socketing protrusion is equipped with a connecting component, which includes a fixing washer and a fixing bolt. The fixing bolts can be adjusted to accommodate I-beams of different flange thicknesses.

[0004] However, the above-mentioned solutions have at least the following technical problems during implementation: Uneven stress distribution: Uneven bolt placement leads to different stresses at the contact points between the I-beam and the vertical beam, making them prone to damage. Risk of bottom beam displacement: The bottom beam is prone to sliding or displacement under stress, affecting construction safety. Inconvenient installation and adjustment: Traditional fixing methods require complex installation steps and are difficult to dynamically adjust. Risk of structural damage: Large-scale similar damage could lead to safety accidents. Therefore, there is an urgent need to propose an I-beam support beam fixing device. Summary of the Invention

[0005] In view of the above technical problems, this disclosure provides an I-beam support beam fixing device, which solves the technical problem in the prior art where uneven bolt arrangement leads to different forces at the contact points between the I-beam and the vertical beam, making it prone to damage and causing safety accidents.

[0006] According to one aspect of this disclosure, an I-beam support beam fixing device is provided, comprising at least two parallel I-beams; the I-beams are mounted on an upright; a bottom beam limiting block is installed on the top of the I-beam for placing the bottom beam; an adjustable slot is correspondingly opened on the I-beam, and a bolt is installed in the adjustable slot for adjusting the position of the bolt to fix the I-beam; the upright has threads for screwing on a tray to support the I-beam.

[0007] In some embodiments of this disclosure, the tray is provided with multiple holes, and a cable is installed between the holes of adjacent uprights.

[0008] In some embodiments of this disclosure, the tray includes an upper disc and a lower ring that are fixedly connected. The lower rings of adjacent uprights are connected by a cable. Two clamping nuts are installed on the outer side of the lower ring, and the end of the cable passes between the two clamping nuts to clamp the cable.

[0009] In some embodiments of this disclosure, the cable has a two-section structure, with a break in the middle and a turnbuckle connection.

[0010] In some embodiments of this disclosure, the turnbuckle includes a connecting sleeve, the inner walls of both ends of which are threaded to accommodate a left-handed screw and a right-handed screw.

[0011] In some embodiments of this disclosure, the bottom beam limiting block includes claws for locking the top two sides of the I-beam, and the claws pass through the mounting and fixing part to fix the claws on the I-beam.

[0012] In some embodiments of this disclosure, an anti-slip structure is provided at the contact point between the top of the I-beam and the bottom beam.

[0013] The beneficial effects of this utility model are as follows:

[0014] The combination of cables and turnbuckles achieves multi-point uniform tension on the I-beam. This effectively distributes stress, preventing structural damage caused by uneven stress and significantly improving the stability of the entire support beam fixing device. The tray is screwed onto the uprights, a connection method that is not only secure and reliable but also allows for height adjustment to further optimize structural stability. The bottom beam limiting block engages with the top two sides of the I-beam using claws and is securely installed via a fixing part. This effectively prevents the bottom beam from shifting or sliding under load, ensuring its stability during operation. The anti-slip structure at the contact point between the top of the I-beam and the bottom beam further increases friction, preventing slippage under load and enhancing the reliability of the bottom beam fixation. The adjustable slots on the I-beam allow the bolts to move within a certain range, enabling flexible adjustment of their position according to actual needs. This not only facilitates installation but also allows for dynamic adjustment based on stress conditions during operation, ensuring the structure remains in optimal condition. The turnbuckle's left-hand and right-hand screw design allows for easy adjustment of the cable tension. The system is dynamically adjusted based on actual stress conditions to ensure the cables maintain appropriate tension at all times. The entire I-beam support structure remains stable under load, preventing safety accidents caused by structural instability. This design significantly improves construction safety, especially in high-risk environments such as building construction. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0020] This example discloses a fixing device for an I-beam support beam; see [link / reference]. Figures 1 to 3It includes at least two parallel H-beams 1; the H-beams 1 are installed on the uprights 2; a bottom beam limiting block 3 is installed on the top of the H-beams 1 for placing the bottom beam 4; an adjustable slot 5 is opened on the H-beams 1, and a bolt 6 is installed in the adjustable slot 5 for adjusting the position of the bolt 6 to fix the H-beams 1; the uprights 2 are threaded to screw on the tray 7 to support the H-beams 1.

[0021] Multiple holes 8 are provided on the tray 7, and a cable 9 is installed between the holes 8 of adjacent uprights 2.

[0022] The bottom beam limiting block 3 includes a claw 17 for locking the top two sides of the I-beam 1. The claw 17 passes through the mounting and fixing part 18 to fix the claw 17 on the I-beam 1.

[0023] An anti-slip structure is installed at the contact point between the top of the I-beam 1 and the bottom beam 4.

[0024] During operation, firstly, the upright 2 is installed in the predetermined position, ensuring its vertical stability to provide sufficient support. The tray 7 is then screwed onto the upright 2. Bolts 6 are installed through the adjustable slot 5 on the I-beam 1. The adjustable slot 5 is an elongated slot that allows the bolts 6 to move within a certain range. The position of the bolts 6 is adjusted according to actual needs to ensure even fixation of the I-beam 1 and avoid uneven stress. Cables 9 are installed between the trays 7 of adjacent uprights 2. The bottom beam limiting block 3 is installed on the top of the I-beam 1. The bottom beam limiting block 3 includes claws 17, which are used to hold the top sides of the I-beam 1, ensuring the bottom beam limiting block 3 is firmly fixed to the I-beam 1. The claws 17 are fixed to the I-beam 1 through a through-mounted fixing part 18. The fixing part 18 can be bolts or other fixing devices, ensuring the bottom beam limiting block 3 is firmly fixed to the I-beam 1. The bottom beam 4 is placed between the bottom beam limiting blocks 3. Ensure that the bottom beam 4 is stably placed on top of the I-beam 1. An anti-slip structure is provided at the contact point between the top of the I-beam 1 and the bottom beam 4 to increase friction and prevent the bottom beam 4 from sliding under load. The anti-slip structure can be an anti-slip mat, anti-slip texture, or other anti-slip device. Example 2

[0025] The principle of this example is the same as that of Example 1, but the specific differences are as follows:

[0026] The pallet 7 includes an upper disc 10 and a lower ring 11 that are fixedly connected. The lower rings 11 of adjacent uprights 2 are connected by a cable 9. Two clamping nuts 12 are installed on the outer side of the lower ring. The end of the cable 9 passes between the two clamping nuts 12 to clamp the cable 9.

[0027] The cable 9 has a two-section structure, with the middle section broken and connected by turnbuckles 13.

[0028] The turnbuckle 13 includes a connecting sleeve 14, the inner walls of both ends of which are threaded to accommodate a left-hand screw 15 and a right-hand screw 16.

[0029] During operation, the pallet 7 is securely mounted on the upright 2 by engaging the internal thread of its upper disc 10 with the external thread of the upright 2. Two parallel I-beams 1 are placed on the upper disc 10 of the pallet 7. The bottom of the I-beams 1 contacts the upper disc 10 of the pallet 7, ensuring stable placement. The cable 9 has a two-section structure, connected in the middle by a turnbuckle 13. The tension of the cable 9 is adjusted by the left-hand screw 15 and the right-hand screw 16 of the turnbuckle 13. The inner walls of the connecting sleeve 14 of the turnbuckle 13 are threaded at both ends, and the left-hand screw 15 and the right-hand screw 16 are screwed in respectively. By rotating the turnbuckle 13, the length of the cable 9 can be adjusted, thereby evenly distributing the force. The end of the cable 9 is passed between the two clamping nuts 12 on the outside of the lower ring 11 of the pallet 7. By tightening the clamping nuts 12, the cable 9 is securely clamped between the clamping nuts 12, preventing the cable 9 from loosening. If uneven stress or other problems are found during operation, the structure can be dynamically adjusted by adjusting the position of bolt 6 and the tightness of turnbuckle 13 to ensure that it is always in the best working condition.
