Description

Technical Field

[0001] This utility model relates to the field of steel structure construction, and in particular to a high-altitude precision installation device for large steel stacked beams. Background Technology

[0002] Large steel truss beams are heavy structural components used in building and bridge engineering. They are usually composed of multiple layers of steel stacked together to provide sufficient strength and rigidity. This type of structure is characterized by its ability to withstand large loads and has good spanning capacity. When installing large steel truss beams at high altitudes, special lifting equipment and techniques are usually required to ensure the accuracy and safety of the installation.

[0003] A search revealed that Chinese Patent Publication No. CN220351531U discloses an adjustment device for high-altitude precision installation of large steel stacked beams. A jack is installed between the lifting device and the upper steel beam. The jack lifts the lower steel beam, ensuring coordinated deformation between the lower and upper steel beams. This guarantees the bolt alignment accuracy of the upper and lower steel beams, ensuring the high-altitude alignment accuracy of the left and right sections of the upper steel beams, as well as the overall high-altitude installation accuracy of the upper and lower steel beams, thereby improving the bolt hole alignment rate of the upper and lower steel beams.

[0004] In the above technical solution, the bolts of the upper and lower steel beams are aligned by the lifting and adjusting devices to facilitate installation. However, when the steel beams need to be assembled, there is a lack of temporary fixing function, which will cause swaying when they are installed close to each other at high altitude, increasing the risk of structural instability. It is impossible to ensure the precise position and alignment of the steel beams, thereby reducing the efficiency of subsequent welding or bolting between steel beams. Therefore, a high-altitude precision installation device for large steel stacked beams is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-altitude precision installation device for large steel stacked beams, which aims to improve the problem that the existing high-altitude precision installation devices for large steel stacked beams cannot provide temporary fixing functions for the steel beams, resulting in the inability to ensure the alignment between the steel beams and reduce the subsequent installation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a large steel stacked beam high-altitude precision installation device, comprising a steel beam one, a steel beam two disposed on the outside of the steel beam one, a lifting lug fixedly connected to the top of the steel beam two, an installation structure disposed on the surface of the steel beam one, the installation structure including a screw hole, a bolt threadedly connected to the inner wall of the screw hole, a positioning component disposed on the surface of the steel beam one, and a locking component disposed on the surface of the steel beam one.

[0007] As a further description of the above technical solution:

[0008] A through plate is fixedly connected to the outer wall of the steel beam, and the surface of the through plate has fixing holes.

[0009] As a further description of the above technical solution:

[0010] The positioning component includes an inclined block 1, and the inclined block 2 is fixedly connected to the side wall of the steel beam 2. The inclined block 2 has a clearance groove on its surface and an installation hole on its surface.

[0011] As a further description of the above technical solution:

[0012] The locking assembly includes a thrust plate, the bottom of which is fixedly connected to a protruding beam, and the surface of the second inclined block is provided with a matching groove.

[0013] As a further description of the above technical solution:

[0014] The side wall of the first inclined block is fixedly connected to the side wall of the first steel beam, and the clearance groove is opened on the side of the second inclined block away from the second steel beam.

[0015] As a further description of the above technical solution:

[0016] The side of the inclined block one that is away from the steel beam one is in contact with the side of the inclined block two that is away from the steel beam two.

[0017] As a further description of the above technical solution:

[0018] The lower surface of the thrust plate is fixedly connected to the upper surface of the inclined block, and the outer wall of the convex beam is adapted to the inner wall of the matching groove.

[0019] As a further description of the above technical solution:

[0020] The thrust plate is located on the outer wall of the steel beam near the inclined block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up an inclined block one and an inclined block two, and fixing the two to steel beam one and steel beam two respectively by bolts and mounting holes, the compatibility of the inclination of the two, together with the convex beam and matching groove, can make steel beam one and steel beam two accurately positioned. The temporary fixing reduces the deviation of subsequent installation, ensures the alignment between the two, reduces the risk of collision or structural damage during installation, and thus improves the safety of the construction site.

[0023] 2. In this utility model, the steel beam one and steel beam two can be installed and fixed by providing an insert plate and fixing holes, which facilitates subsequent welding between the two or welding with other structures. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a large-scale steel stacked beam high-altitude precision installation device, including a steel beam 1, a steel beam 2 on the outside of the steel beam 1, a lifting lug 3 fixedly connected to the top of the steel beam 2, the lifting lug 3 can lift the steel beam 1 and the steel beam 2 through an external lifting device, the surface of the steel beam 1 is provided with an installation structure, the installation structure includes screw holes 4, the inner wall of the screw holes 4 is threaded with bolts 8, the steel beam 1 and the steel beam 2 are provided with equally spaced screw holes 4 on the side close to each other, the surface of the steel beam 1 is provided with a positioning component, and the surface of the steel beam 1 is provided with a locking component.

[0033] Reference Figures 3-5 The positioning assembly includes an inclined block 5, the side of which is away from the steel beam 1 and the side of an inclined block 9 away from the steel beam 2 are attached. The sidewall of the inclined block 5 is fixedly connected to the sidewall of the steel beam 1, and the sidewall of the steel beam 2 is fixedly connected to the inclined block 9. A clearance groove 6 is provided on the surface of the inclined block 9, located on the side of the inclined block 9 away from the steel beam 2. The materials of the inclined blocks 5 and 9 are the same as those of the steel beams 1 and 2. The center point of the clearance groove 6 is on the same horizontal line as the center point of the mounting hole 7. The clearance groove 6 allows the bolt 8 to be tilted... The surfaces of inclined block 1 5 and inclined block 2 9 are not in a protruding state. The surface of inclined block 2 9 is provided with mounting holes 7. The locking assembly includes a thrust plate 10. The thrust plate 10 is located on the outer wall of steel beam 1 near inclined block 1 5. The lower surface of the thrust plate 10 is fixedly connected to the upper surface of inclined block 1 5. The bottom of the thrust plate 10 is fixedly connected to a protruding beam 11. The outer wall of the protruding beam 11 is adapted to the inner wall of the matching groove 12. The surface of inclined block 2 9 is provided with a matching groove 12. The matching groove 12 allows the protruding beam 11 to be embedded inside, so that steel beam 2 2 and steel beam 1 1 are positioned.

[0034] Reference Figure 3 and Figure 5 A through plate 13 is fixedly connected to the outer wall of steel beam 1. The surface of the through plate 13 is provided with fixing holes 14. There are two sets of through plates 13, and the two sets of through plates 13 are respectively alternately located on the outer wall of steel beam 1 and steel beam 2 on the opposite side. The fixing holes 14 can be connected by external screws.

[0035] Working principle: The inclined block 5 is placed close to the side wall of steel beam 1. Bolts 8 are inserted into the clearance groove 6 until they gradually connect with the mounting hole 7 and are then fixed to the screw hole 4. Since inclined block 5 is inclined, the bolts 8 are gradually lengthened according to the degree of inclination to fix inclined block 5 to the surface of steel beam 1. The above steps are repeated to fix inclined block 9 to steel beam 2. Steel beam 1 is first lifted using lifting lugs 3, and then steel beam 2 is lifted in the same way. Steel beam 2 gradually moves upward towards steel beam 1, and inclined block 5 and inclined block 9 gradually come together until they bulge. Beam 11 is inserted into the matching slot 12 until steel beam 2 can no longer rise or move. At this time, the two sets of through plates 13 are in a close fit, and steel beam 1 and steel beam 2 are temporarily fixed. External screws are used to fix them between the two sets of through plates 13. Then, external equipment is used to weld steel beam 1 and steel beam 2 together. Accurate positioning can reduce the adjustment time of the steel in the air and ensure the alignment between steel beam 1 and steel beam 2. This provides convenience for subsequent construction steps, such as welding, bolting, or installation of other building components, and ensures the smooth progress of subsequent work.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
