Description

Technical Field

[0001] This utility model relates to the field of steel structure installation equipment technology, and in particular to an auxiliary positioning device for connecting steel structure beams. Background Technology

[0002] In the field of steel structure construction, vertical connections between steel beams are a common construction step. Traditionally, when two steel beams need to be vertically connected (e.g., a T-connection between a main beam and a secondary beam), hoisting equipment is typically used in conjunction with lifting ropes or temporary supports for positioning and installation. However, existing technologies have the following problems: insufficient stability, as the steel beams are easily affected by wind or external forces during hoisting, making it difficult to quickly align the joint ends, especially in high-rise or large-span construction, posing significant safety hazards; and due to the lack of reliable auxiliary positioning devices, misalignment or gaps may occur during steel beam connection, requiring repeated adjustments, which not only affects construction efficiency but also the quality of welding or bolt fixing, and may even lead to substandard structural strength.

[0003] Therefore, there is an urgent need for an auxiliary positioning device for steel beam connection that can provide support for the installation of steel beams, ensure construction quality, and improve construction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary positioning device for steel structure beam connection, which can provide support for steel beam connection and installation, ensure construction quality, improve construction efficiency, and reduce safety hazards.

[0005] The present invention adopts the following technical solution:

[0006] A steel structure beam connection auxiliary positioning device includes a vertically arranged support frame, a support plate vertically arranged on the side wall of the support frame, a support beam vertically arranged on the support frame below the support plate, and a receiving plate arranged on the support beam, wherein the receiving plate can be adjusted in height relative to the support beam.

[0007] Preferably, the support plate is provided in two sets, upper and lower, on the support frame.

[0008] Preferably, the support plate located below is adjustablely mounted on the support frame.

[0009] Preferably, rollers are rotatably provided on the opposite end faces of the upper and lower support plates.

[0010] Preferably, two support beams are provided.

[0011] Preferably, the bottom of the receiving plate is provided with a screw, each of the supporting beams is provided with a through hole for the screw to pass through, and nuts are threaded on the screws at the upper and lower ends of the supporting beams.

[0012] Preferably, a reinforcing plate is provided between the supporting beam and the support frame.

[0013] Preferably, a reinforcing plate is provided between the support plate and the support frame.

[0014] Preferably, a top plate is vertically provided at the top of the support frame, and an L-shaped limiting plate is provided on one side of the top plate.

[0015] Preferably, the top plate and the limiting plate are integrally formed, and the width of the top plate gradually decreases from the end near the support frame to the end near the limiting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: By placing the support plate on the top of the lower flange of the non-connecting side of the steel beam to be connected, the support beam can extend from the bottom of the steel beam to be connected, and the receiving plate is located on the support beam on the outside of the steel beam to be connected, providing stable support for the steel beam to be connected, which greatly ensures the docking effect and connection efficiency when the two steel beams are connected; at the same time, it reduces the probability of the steel beam shaking due to external forces, and improves the safety of construction; the height of the receiving plate can be adjusted to adapt to the needs of steel beams with different cross-sectional sizes or installation heights, which is highly versatile and reduces the cost and time of replacing special tools.

[0019] Figure 3 This is a diagram showing the usage status of the auxiliary positioning device according to an embodiment of this application. Detailed Implementation

[0020] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0021] like Figures 1 to 3As shown, the auxiliary positioning device for connecting steel structure beams according to this utility model includes a vertically arranged support frame 1, which consists of two vertically arranged steel pipes and a steel cross brace set between the two steel pipes. Support plates 2 are vertically arranged on the side wall of the support frame 1. There are two support plates 2, located on the two steel pipes respectively. Support beams 3 are vertically arranged on the support frame 1 below the support plates 2. The length of the support beams 3 is greater than the width of the steel beams 4 to be connected. There are two support beams 3, which are connected to the corresponding steel pipes by welding. A receiving plate 5 is provided on the support beam 3. The receiving plate 5 can be adjusted in height relative to the support beam 3 to adapt to the needs of steel beams with different cross-sectional dimensions or installation elevations, ensuring the connection effect of the steel beams, expanding the applicability of this device, and reducing the cost and time of replacing special tools. Specifically, the bottom of the receiving plate 5 is provided with two screws 6, and each support beam 3 is provided with a through hole for the screws 6 to pass through. Nuts 7 are threaded on the screws 6 at both ends of the support beam 3. By adjusting the position of the nuts 7 on the screws 6, the height of the receiving plate 5 can be adjusted to meet the usage requirements under various working conditions.

[0022] Furthermore, the support plate 2 is provided on the support frame 1 in two sets, upper and lower. Preferably, the two sets of support plates 2 are arranged symmetrically, with a slot structure formed between the upper and lower support plates 2 on each side. This slot structure allows the support plate 2 to engage with the lower flange of the steel beam to be connected, completing the installation of the support frame 1 onto the steel beam 4. Preferably, the lower support plate 2 is adjustable on the support frame 1 to allow for adjustment of the slot size, accommodating various types of steel beams. Specifically, the lower support plate 2 is provided with a threaded rod, and the support frame 1 has an adjustment slot. The threaded rod passes through the adjustment slot and a nut is installed thereon, achieving a fixed connection between the lower support plate 2 and the support frame 1. It is worth noting that the steel beam to be connected mentioned in this example refers to... Figure 3 The steel beams in the middle, the steel beams to be connected are with Figure 3 The steel beams vertically connected in the diagram are not shown and are used to connect to the steel beams mounted on the same structure via bolts. Figure 3 The connecting plates in the upper and lower flanges of the steel beam 4 are connected.

[0023] In addition, rollers 8 are rotatably installed on the opposite end faces of the upper and lower support plates 2. The two symmetrical rollers 8 are located on the upper and lower sides of the lower flange of the connected steel beam 4, respectively. The rollers 8 are made of steel to ensure their load-bearing strength. The rollers 8 are installed to facilitate the sliding support frame 1 to move along the length of the connected steel beam 4 to the next location after the steel beams are connected at one point, thus improving the convenience of operation. It also facilitates the sliding support frame 1 after the two steel beams are connected, so that the receiving plate 5 can be removed from the bottom of the steel beam to be connected, making it convenient for the positioning device to be removed from the connected steel beam 4.

[0024] In this embodiment, reinforcing plates 9 are provided between the support beam 3 and the support frame 1, and between the support plate 2 and the support frame 1, to ensure the strength of the connection between the support beam 3 and the support frame 1, and between the support plate 2 and the support frame 1, and to enhance its load-bearing capacity.

[0025] Furthermore, a top plate 10 is vertically installed at the top of the support frame 1, and an L-shaped limiting plate 11 is installed on one side of the top plate 10. A limiting groove is formed between the limiting plate 11 and the top plate 10. The limiting groove is used to lock onto the upper flange of the connecting side of the connected steel beam 4, increasing the stability of this positioning device during use. Both the top plate 10 and the limiting plate 11 are integrally formed from steel plates, and the width of the top plate 10 gradually decreases from the end near the support frame 1 to the end near the limiting plate 11. This reduces weight and minimizes the impact on the connection of the steel beams. By placing the limiting plate 11 on one side of the top plate 10, the connection point of the two steel beams can be avoided, thus preventing interference with the normal installation of the steel beams.

[0026] In use, this utility model first uses the limiting groove formed by the limiting plate 11 and the top plate 10 to lock onto the upper flange of the connecting side of the steel beam 4. Then, the distance between the upper and lower support plates 2 is adjusted according to the flange thickness of the steel beam 4, so that the lower flange of the upper steel beam 4 is located between the upper and lower rollers 8 and in contact with the rollers 8. At this time, the installation of the positioning device is completed. Finally, the height of the receiving plate 5 is adjusted according to the size of the steel beam to be connected. By placing the steel beam to be connected on the receiving plate 5, the stability of the steel beam connection is greatly guaranteed, which improves both construction efficiency and construction quality. At this time, the hoisting rope does not need to be removed, which can realize double insurance for construction and improve construction safety. After the steel beams are connected, adjust the lower rollers 8 to increase the distance between the upper and lower rollers 8. At the same time, push the support frame 1 to move it towards the connected steel beam 4 (because the support plate has a certain length, a gap is stored between the support frame 1 and the connected steel beam 4 after installation to reserve space for the support frame 1 to move towards the connected steel beam 4). This forces the limiting plate 11 to move out from the lower part of the upper flange of the connected steel beam 4. At this time, lift the support frame 1, and the limiting plate 11 will be located on the upper part of the connected steel beam 4. Then pull the support frame 1 back. If there are connecting components on one side of the connected steel beam 4, the support frame 1 can also be slid to slide off from the connected steel beam 4.
