Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a flange beam fixing component. Background Technology

[0002] Before some building construction, a support system needs to be built first. Taking bridge construction as an example, the support system before construction mainly consists of steel pipe columns, flanges, I-beams and crossbeams. During construction, the bottom of the flange is welded to the top of the steel pipe column. There are usually multiple I-beams, which are welded to the top of the flanges one after another. Then, the crossbeams are placed between two adjacent I-beams.

[0003] The above method effectively secures the steel pipe columns, flanges, and I-beams, and the crossbeams also achieve good fixation under the limiting effect of the I-beams. However, this method has the following problems: 1. For ease of transportation and handling, the I-beams need to be welded during the construction of the support system. Welding in the field is inconvenient due to limited electricity and time-consuming, requiring workers to work at heights for extended periods, posing significant safety hazards. 2. After the bridge is built, the support system needs to be dismantled. During dismantling, the welded joints between the I-beams and flanges need to be cut, and then the crossbeams, I-beams, and steel pipe columns are lifted away by crane. Because it is difficult to accurately determine whether the welded joints have been cut, the lifting process can easily become unbalanced, leading to safety accidents. Utility Model Content

[0004] The present invention aims to provide a flange beam fixing assembly to improve the ease of loading and unloading of I-beams and steel pipe columns.

[0005] This solution provides a flange beam fixing assembly, including a flange, a fixing mechanism and two abutment mechanisms connected to the flange. Each abutment mechanism includes a base plate and an abutment plate for abutting the web of an H-beam. The abutment plate is fixedly connected to the top of the base plate, and a connecting plate is fixedly connected to the bottom of the base plate. The top of the flange has two limiting holes that mate with the connecting plate. The two limiting holes are located on the same vertical plane and close to opposite ends of the flange. The connecting plate has a through-hole fixing hole, the extension direction of which is perpendicular to its length direction. The fixing mechanism includes a fixing plate and a bolt rotatably connected to one end of the fixing plate. The diameter of the bolt shank is larger than the width and height of the fixing plate. The flange has a through-hole connecting hole, and the outer wall of the flange has a threaded hole that mates with the bolt shank. After the connecting plate is connected to the limiting hole, the fixing hole and the connecting hole are on the same straight line, and the fixing plate is clearance-fitted with the connecting hole and the fixing hole.

[0006] The working principle of this solution is as follows: When constructing the building support system, the flange is pre-welded to the top of the steel pipe column. After the steel pipe column is transported to the specific location and fixed, the base plate of one of the supporting mechanisms is placed at the required installation position. The connecting plate of the supporting mechanism is aligned with the limiting hole on the top of the flange, and the connecting plate is inserted into the limiting hole. Then, the end of the fixing plate away from the bolt is connected to the fixing hole of the connecting plate through the threaded hole and the connecting hole, so that the supporting mechanism is initially positioned on the flange. At this time, the fixing hole on the connecting plate and the connecting hole on the flange are on the same straight line.

[0007] Next, place the I-beams on top of the flange, with the web of the first I-beam abutting against the abutting plate of the installed abutting mechanism. Then, place the I-beams on top of the flange one by one, with multiple I-beams placed close together in sequence. After the I-beams are placed, place the base plate of the second abutting mechanism at the required installation position. At this time, the abutting plates of the two abutting mechanisms abut against the webs of the two I-beams at the outer ends, respectively.

[0008] Next, insert the fixing plate of the fixing mechanism into another fixing hole, and then rotate the bolt so that the bolt shank is screwed into the threaded hole on the outer wall of the flange. As the bolt is tightened, it pushes the fixing plate to move, and the fixing plate is connected to the connecting plate, thus firmly fixing the fixing plate in the limiting hole, achieving a stable connection between the holding mechanism and the flange.

[0009] When dismantling the support system, turn the bolts in the opposite direction to unscrew them from the threaded holes, then remove the fixing plate, and then pull the connecting plate of the abutment mechanism out of the limiting hole. The abutment mechanism and the I-beam can then be disassembled, which is very convenient.

[0010] The advantages of this solution are as follows: During installation, simply insert the two connecting plates into the corresponding limiting holes, then insert the fixing plate and tighten the bolts to connect the I-beam and the steel pipe column. Disassembly is simple: just loosen the bolts and remove the fixing plate and the supporting mechanism to separate the I-beam from the flange.

[0011] Furthermore, there are two fixing mechanisms and two threaded holes located at both ends of the connecting hole. The two fixing mechanisms can simultaneously apply fixing force from both ends of the connecting hole, making the connection between the supporting mechanism and the flange more uniform. The two fixing mechanisms shorten the length of the fixing plate, making operation more convenient, and the two bolts sealing the connecting hole reduce rainwater ingress, helping to extend the service life of the flange and the fixing plate.

[0012] Furthermore, a connecting rod is integrally formed at the end of the bolt shank away from the head, and the connecting rod is rotatably connected to one end of the fixing plate. The rotatable connection between the connecting rod and the fixing plate ensures that the bolt remains connected to the fixing plate during installation or disassembly, preventing the bolt from accidentally falling off during high-altitude operations.

[0013] Furthermore, the base plate is of a slightly curved shape. This helps increase the bending stiffness of the base plate itself. When subjected to the pressure of the I-beam, the curved structure can distribute the load to the entire base plate, reducing local deformation.

[0014] Furthermore, the supporting plate is welded or integrally formed onto the base plate. This welding or integral forming method ensures high connection strength and stability between the supporting plate and the base plate.

[0015] Furthermore, there are multiple limiting holes, and a limiting mechanism is movably connected to the flange. The limiting mechanism includes a base plate and limiting plates that mate with the limiting holes. There are two limiting plates, which are fixedly connected to the bottom of the base plate. The limiting plates also have through holes. The limiting mechanism is located between two adjacent H-beams, and the length of the base plate is less than the distance between the webs of the two adjacent H-beams. In use, through holes that mate with the limiting plates are pre-drilled in the lower flange of the H-beams. After the limiting plates are inserted into the through holes and limiting holes between adjacent H-beams, the fixing plates can be inserted into the fixing holes of the limiting plates to further limit the H-beams and improve stability.

[0016] Furthermore, the aforementioned limiting mechanism is provided between adjacent I-beams. This further improves the stability of the connection between the I-beams and the flange.

[0017] Furthermore, a rubber pad is fixedly connected to the bottom of the substrate. The elastic material of the rubber pad increases the friction between the substrate and the top surface of the I-beam. More importantly, it prevents the substrate from deforming due to pressure from the crossbeam. Attached Figure Description

Detailed Implementation

[0029] The following detailed description illustrates the specific implementation method:

[0030] Example 1 is basically as shown in the appendix. Figures 1-5 As shown: A flange beam fixing assembly includes a flange 1, which is circular. A fixing mechanism and two abutment mechanisms are connected to the flange 1. Specifically: the flange 1 is provided with a through-hole, and the outer wall of the flange 1 is provided with two threaded holes. The two threaded holes are located at both ends of the connecting hole, and the threaded holes are connected to the connecting hole and are in a straight line.

[0031] The supporting mechanism includes a base plate 3 and a supporting plate 4 for supporting the web of the I-beam 12. The base plate 3 is in the shape of a minor arc. The supporting plate 4 is welded to the top of the base plate 3. A connecting plate 6 is integrally formed at the bottom of the base plate 3. The top of the flange 1 is provided with two limiting holes 8 that cooperate with the connecting plate 6. The two limiting holes 8 are located on the same vertical plane and close to the opposite ends of the flange 1. The connecting plate 6 is provided with a fixing hole that passes through it. The extension direction of the fixing hole is perpendicular to its length direction.

[0032] There are two fixing mechanisms, as shown in the attached document. Figures 3-4 As shown, it includes a fixing plate 5 and a bolt 2 rotatably connected to one end of the fixing plate 5. The bolt 2 is used in conjunction with a threaded hole. Specifically, the end of the bolt 2 away from the head has an integrally formed connecting rod 7, which is rotatably connected to one end of the fixing plate 5 via a bearing. The diameter of the bolt 2 shank is greater than the width and height of the fixing plate 5. After the connecting plate 6 is connected to the limiting hole 8, the fixing hole and the connecting hole are on the same straight line. The fixing plate 5 is clearance-fitted with the connecting hole and the fixing hole, and the two fixing plates 5 are inserted into the corresponding fixing holes.

[0033] Detailed implementation method: When constructing the building support system, flange 1 is welded to the top of steel pipe column 13 beforehand. After transporting and fixing the steel pipe column 13 to a specific location, the base plate 3 of one of the supporting mechanisms is placed at the required installation position. The connecting plate 6 of the supporting mechanism is aligned with the limiting hole 8 on the top of flange 1, and the connecting plate 6 is inserted into the limiting hole 8. Then, the end of the fixing plate 5 of a fixing mechanism away from bolt 2 is connected to the fixing hole of the connecting plate 6 through the threaded hole and the connecting hole. Subsequently, bolt 2 is rotated so that the shank of bolt 2 is screwed into the threaded hole on the outer wall of flange 1. As bolt 2 is continuously tightened, bolt 2 will push the fixing plate 5 to move, thereby firmly fixing the fixing plate 5 in the limiting hole 8, realizing a stable connection between the supporting mechanism and flange 1.

[0034] Next, place the I-beam 12 on top of the flange 1, with the web of the first I-beam 12 abutting against the abutment plate 4 of the installed abutment mechanism. Then, place the I-beams 12 one by one on top of the flange 1, with the three I-beams 12 placed close together. After the I-beams 12 are placed, place the base plate 3 of the second abutment mechanism in the desired installation position. At this point, the abutment plates 4 of the two abutment mechanisms abut against the webs of the two outermost I-beams 12. Next, insert the fixing plate 5 of another fixing mechanism into another fixing hole, and then rotate the bolt 2 so that the shank of the bolt 2 is screwed into the threaded hole on the outer wall of the flange 1. As the bolt 2 is tightened, it pushes the fixing plate 5 to move, thereby firmly fixing the fixing plate 5 in the limiting hole 8, achieving a stable connection between the abutment mechanism and the flange 1. After fixing the I-beam 12, place the crossbeam 11 between the adjacent I-beams 12, and use the limiting effect of the I-beam 12 on the crossbeam 11 to form a stable support system.

[0035] When dismantling the support system, rotate bolt 2 in the opposite direction to unscrew it from the threaded hole, then remove the fixing plate 5, and then pull the connecting plate 6 of the abutment mechanism out of the limiting hole 8. The abutment mechanism and the I-beam 12 can then be disassembled.

[0036] Example 2 is basically as shown in the appendix. Figures 6-7 As shown, the only difference between this embodiment and embodiment 1 is that there are six limiting holes 8 and two limiting mechanisms are movably connected to the flange 1. The limiting mechanism includes a base plate 9 and a limiting plate 10 that works with the limiting holes 8. There are two limiting plates 10, which are integrally formed on the bottom of the base plate 9. The two limiting plates 10 are arranged in parallel. The limiting plate 10 is also provided with a fixing hole that passes through it. The limiting mechanism is located between two adjacent I-beams 12.

[0037] Detailed Implementation: The operation process is basically the same as in Example 1, except that: a through hole for use with the limiting plate 10 needs to be pre-drilled on the lower flange of the I-beam 12; when installing the first fixing mechanism, do not tighten the bolt 2 first, and the fixing plate 5 should just extend beyond the connecting plate 6 of the first abutment mechanism. After the installation of the two I-beams 12 is completed, insert the limiting plate 10 of the first limiting mechanism into the through hole and limiting hole 8 between adjacent I-beams 12, and then push the fixing plate 5 until it passes through the fixing hole of the limiting plate 10. Tighten the bolt 2. Install the third I-beam 12, install the second limiting mechanism, and install the second fixing mechanism. After the I-beams 12 are fixed, place the crossbeam 11 between adjacent I-beams 12, and use the limiting effect of the I-beams 12 on the crossbeam 11 to form a stable support system (as shown in the attached figure). Figure 8 (As shown).

[0038] Example 3 is basically as shown in the appendix. Figure 9 As shown, the only difference between this and Example 2 is that a rubber pad 14 is adhered to the bottom of the substrate 9.

[0039] Detailed Implementation: The installation process in Example 3 is the same as in Example 2. After fixing the I-beams 12, the crossbeams 11 are placed between adjacent I-beams 12. The I-beams 12 limit the crossbeams 11, forming a stable support system (as shown in the attached diagram). Figure 10 (As shown).
