Description

Technical Field

[0001] This utility model relates to the technical field of large-span steel structure construction, and in particular to a temporary fixing device for steel beam connecting plates. Background Technology

[0002] Large-span steel structure projects are becoming increasingly common, especially in urban complex buildings. These complexes are characterized by their large spans and deep dimensions. To achieve better views and a better user experience, the cross-sections of their steel beams are much larger than those of conventional commercial or office buildings, and their spans are several times greater than those of conventional components. Due to the increased cross-section of the steel beams, the specifications of the connecting plates also increase, typically weighing around 200-300 kg. If the connecting plates are not securely fixed during the hoisting of the steel beams, they may fall from a great height. If they are too securely fixed, the connecting plates may not be able to be properly connected to the steel beams.

[0003] The existing technical solution involves directly binding the steel beam connecting plate to the upper flange of the H-shaped steel beam. The steel beam connecting plate is lifted directly along with the steel beam. After it is in place, the workers manually untie the steel beam connecting plate from the upper flange of the steel beam, and then connect the steel beam connecting plate to the steel beam. In this construction process, the connecting plate needs to be lifted and transported manually, which is extremely dangerous and inefficient. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a temporary fixing device for steel beam connecting plates.

[0005] This utility model provides a temporary fixing device for steel beam connecting plates, which adopts the following technical solution: A temporary fixing device for a steel beam connecting plate includes a steel beam, hooks, and a connecting plate. The connecting plate has multiple first connecting holes. Multiple hooks are arranged sequentially from top to bottom on the web of the steel beam. Each hook includes an integrally formed fixing part, mounting part, and alignment part. The fixing part is connected to the web of the steel beam. The alignment part and mounting part of the hook pass through one of the first connecting holes. The connecting plate is perpendicular to the web of the steel beam. The web of the steel beam has second connecting holes. The alignment part is aligned with one of the second connecting holes and is perpendicular to the web of the steel beam. The mounting part is perpendicular to the alignment part.

[0006] Optionally, a bracket is provided on one side of the steel beam. Multiple third connection holes are provided on the web of the bracket. After the connecting plate is rotated 90 degrees, the first connection holes on one part of the connecting plate are aligned with the third connection holes on the web of the bracket, and the first connection holes on the other part of the connecting plate are aligned with the second connection holes on the web of the steel beam. High-strength bolts pass through the first connection holes and the third connection holes and are connected with nuts. High-strength bolts also pass through the first connection holes and the second connection holes and are connected with nuts.

[0007] Optionally, a mounting plate is fixed to the fixing part of the hook, and a fixing block is welded and fixed to the web of the steel beam. Each mounting plate corresponds to two fixing blocks.

Detailed Implementation

[0011] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be described in further detail below.

[0012] Embodiment 1 of this utility model Reference Figure 1 , Figure 2 and Figure 3This utility model discloses a temporary fixing device for a steel beam connecting plate, including a steel column 1. A bracket 2 is welded and fixed to the side wall of the steel column 1. A steel beam 3, which is an I-beam, is provided on the side of the bracket 2 away from the steel column 1. The steel beam 3 and the bracket 2 are connected and fixed by a connecting plate 4. The cross-section of the bracket 2 on the side of the bracket 2 closest to the steel beam 3 is the same as the cross-section of the steel beam 3.

[0013] Multiple rows of first connecting holes 41 are provided on the connecting plate 4. Multiple rows of second connecting holes 31 are provided on the web of the steel beam 3 near the corbel 2. Multiple rows of third connecting holes 21 are provided on the web of the corbel 2 near the steel beam 3. The sum of the number of rows of second connecting holes 31 and third connecting holes 21 is equal to the number of rows of first connecting holes 41. The diameters of the first connecting holes 41, second connecting holes 31, and third connecting holes 21 are equal.

[0014] Multiple hooks 5 are welded to the web of the steel beam 3. The multiple hooks 5 are arranged in a row on the web of the steel beam 3. The number of hooks 5 can be set according to the height of the steel beam 3: 2 hooks 5 for beam height of 0.8m-1m; 3 hooks 5 for beam height of 1-1.5m; and 5 hooks 5 for beam height of 1.5-2m.

[0015] The hook 5 includes an integrally formed fixing part 51, mounting part 52, and alignment part 53. The mounting part 52 is located between the fixing part 51 and the alignment part 53. The fixing part 51 is welded and fixed to the web of the steel beam 3. There is a gap between the alignment part 53 and the web of the steel beam 3. The alignment part 53 is aligned with one of the second connecting holes 31 in a row of second connecting holes 31 away from the corbel 2. The axis of the alignment part 53 is perpendicular to the web of the steel beam 3, and the mounting part 52 is arranged perpendicularly to the alignment part 53. The connecting plate 4 is inserted between the hook 5 and the web of the steel beam 3 through the gap. The first connecting hole 41 on the connecting plate 4 is inserted into the alignment part 53, so that the connecting plate 4 is in the mounting part 52 of the hook 5.

[0016] When connecting the bracket 2 and the steel beam 3, first weld the fixing part 51 of the hook 5 to the appropriate position on the web of the steel beam 3 on the ground, so that the alignment part 53 is aligned with the corresponding second connecting hole 31. Then place the connecting plate 4 on the mounting part 52 of the hook 5, and hoist the steel beam 3 and the connecting plate 4 together, with the connecting plate 4 being hoisted along with the steel beam 3. After aligning the steel beam 3 with the bracket 2, rotate the connecting plate 4 along the hook 5 so that the multiple first connecting holes 41 on the connecting plate 4 are aligned with the second connecting hole 31 and the third connecting hole 21 respectively. High-strength bolts pass through the first connecting holes 41 and the second connecting holes 31 to fix the connecting plate 4 and the steel beam 3, and high-strength bolts pass through the second connecting holes 31 and the third connecting hole 21 to fix the connecting plate 4 and the bracket 2. Nuts are connected to the high-strength bolts. Ordinary bolts are installed first for positioning and correction before installing the high-strength bolts, and then the ordinary bolts are replaced with high-strength bolts.

[0017] Embodiment 2 of this utility model Reference Figure 4 and Figure 5 The difference from Embodiment 1 lies in the connection method between the hook 5 and the web of the steel beam 3. An mounting plate 6 is fixed to the fixing part 51 of the hook 5, and a fixing block 61 is welded and fixed to the web of the steel beam 3. Each mounting plate 6 corresponds to two fixing blocks 61, which are arranged vertically. Each fixing block 61 has a mounting groove 62 on its side closest to each other. The mounting plate 6 is inserted into the mounting groove 62, and a limiting plate 63 is fixed to one end of the mounting plate 6. When installing the hook 5, the mounting plate 6 is inserted into the mounting groove 62. When the alignment part 53 is aligned with the second connecting hole 31, the limiting plate 63 contacts the end of the fixing block 61. The mounting plate 6 is detachably connected to the web of the steel beam 3, facilitating the disassembly of the hook 5.

[0018] A limiting sleeve 64 is threaded onto the alignment part 53. The limiting sleeve 64 passes through a second connecting hole 31 aligned with the alignment part 53. The outer diameter of the limiting sleeve 64 is smaller than the diameter of the second connecting hole 31. The alignment part 53 is inserted into the limiting sleeve 64 and threadedly connected to it. The limiting sleeve 64 ensures the stability of the connecting plate 4, preventing it from falling off the hook 5 when the steel beam 3 is lifted. When lifting the steel beam 3, after aligning the steel beam 3 with the bracket 2, the limiting sleeve 64 is unscrewed, and the connecting plate 4 is rotated 90 degrees. The connecting plate 4, bracket 2, and steel beam 3 are then connected using high-strength bolts. Afterward, the hook 5 and mounting plate 6 are disassembled.

[0019] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
