Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a rapid assembly tool for steel structures. Background Technology

[0002] As a crucial component of building steel structures, steel columns require high verticality during construction, directly impacting the overall verticality, horizontality, and stability of the steel structure. The verticality of a steel column refers to its deviation from the vertical plane. During construction, straightening and installation are necessary to ensure that the verticality of the connected steel column sections meets the requirements.

[0003] In traditional steel column installation, straightening relies on the auxiliary fixing of guy ropes or the use of auxiliary tools and jacks. When using guy ropes, they must be securely connected to the structure and fixed with specialized securing devices to prevent loosening and falling off. The tension of the guy ropes must also be maintained within an appropriate range; excessive or insufficient tension will affect safety. Simultaneously, collisions between the guy ropes and the tower crane must be prevented, making the operation quite difficult. Furthermore, this method is not conducive to straightening the steel column and the installation speed is slow. When using jacks for auxiliary straightening, especially under heavy loads, slippage or tipping may occur, increasing safety hazards. Achieving high-precision control of jack straightening is also quite challenging, sometimes even leading to slight deviations in the verticality and position of the column. Another part of the operation involves welding connecting lugs onto the installed steel columns and the steel columns to be installed. The connecting lugs are then connected by connecting plates to achieve a vertical connection between the two sections of the steel columns. After the connection is completed, the lugs need to be cut. This operation is quite cumbersome, and the welding and cutting of the lugs can easily damage the steel columns.

[0004] Therefore, there is an urgent need for a rapid steel structure assembly tool that is simple in structure, easy to operate and use, can improve construction efficiency, reduce labor intensity, and improve construction safety, without damaging the steel columns. Utility Model Content

[0005] The purpose of this utility model is to provide a quick assembly tool for steel structures. It has a simple structure, is easy to operate and use, can effectively improve construction efficiency, reduce labor intensity and improve construction safety, and will not damage the steel columns. It is reusable and highly practical.

[0006] The present invention adopts the following technical solution:

[0007] A rapid assembly tool for steel structures includes two fixed corner plates arranged diagonally. Each fixed corner plate has outwardly extending connecting plates on both sides. Connecting screws are passed through the connecting plates on the same side of the two fixed corner plates, and locking nuts are provided at both ends of the connecting screws. An operating space is formed between the two connecting plates on each side.

[0008] Preferably, the horizontal cross-section of the connecting plate is a right-angled trapezoid.

[0009] Preferably, the connecting plate can be slidably adjusted relative to the fixed angle plate.

[0010] Preferably, a slider is provided on one side of the connecting plate, a fixing screw is provided on the slider, a sliding groove is provided at the end of the fixing angle plate that contacts the connecting plate, a movable hole communicating with the sliding groove is opened on the side wall of the fixing angle plate, and a positioning nut is provided on the fixing screw after it moves out of the movable hole.

[0011] Preferably, the slider and the connecting plate are integrally formed.

[0012] Preferably, the fixing screw is detachably mounted on the slider.

[0013] Preferably, the fixing screw is threadedly connected to the slider.

[0014] Preferably, the bottom of the chute is open.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This utility model only requires two fixing angle plates to be symmetrically arranged at the diagonal points of the installed steel column and the steel column to be installed, and the two fixing angle plates are connected by connecting screws to achieve the alignment and connection of the steel column to be connected with the installed steel column. Then, the connection seam of the two steel columns can be welded in the operating channel formed between the two connecting plates, which is simple and quick to operate; This utility model can quickly achieve precise alignment of two steel columns, providing favorable assistance for welding operations and avoiding safety hazards during steel column shaking and straightening; At the same time, the tool can be disassembled and reused after welding, saving usage costs.

[0017] Figure 2 This is an exploded view of the fixed corner plate and the connecting plate in an embodiment of this application;

[0018] Figure 3 This is a structural schematic diagram of the fixed corner plate in an embodiment of this application. Detailed Implementation

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 3 As shown, the present invention provides a rapid assembly tool for steel structures, comprising two diagonally arranged fixed corner plates 1. Each fixed corner plate 1 has outwardly extending connecting plates 2 on both sides. Connecting screws 3 are threaded through the connecting plates 2 on the same side of the two fixed corner plates 1. The number of connecting screws 3 is matched to the height of the connecting plates 2. Adjacent connecting screws 3 are spaced apart. Locking nuts 4 are provided at both ends of each connecting screw 3. The two fixed corner plates 1 are fixedly connected by screwing the locking nuts 4 onto the connecting screws 3. An operating space is formed between the two connecting plates 2 on each side, which facilitates the connection of two steel sections. The connection gap 6 between the already installed steel column 5 and the steel column 5 to be connected is exposed to facilitate welding. After the exposed part is welded, the two steel column sections 5 are initially fixed. At this time, the fixing angle plate 1 can be removed, and welding can be performed on the area covered by the fixing angle plate 1 and the connecting plate 2. The whole process will not damage the steel column 5, ensuring that the strength of the steel column 5 is not affected. By fixing the two steel column sections 5 with two fixing angle plates 1, the two steel column sections 5 can be quickly aligned and connected, reducing the excessive equipment required for straightening and the safety hazards in the existing technology. It is convenient to operate and highly practical.

[0021] Furthermore, the horizontal cross-section of the connecting plate 2 is a right-angled trapezoid to ensure its structural strength. In this embodiment, both the connecting plate 2 and the fixed angle plate 1 are made of steel plates of a certain thickness. Preferably, the connecting plate 2 can be slidably adjusted relative to the fixed angle plate 1 to adjust the spacing between adjacent connecting plates 2 along the side of the steel column 5, thereby accommodating the assembly of steel columns 5 of multiple sizes. Specifically, a slider 7 is provided on one side of the connecting plate 2, and a fixing screw 8 is provided on the slider 7. A groove 9 is provided at the end of the fixed angle plate 1 that contacts the connecting plate 2. A moving hole 10 communicating with the groove 9 is opened on the side wall of the fixed angle plate 1. The slider 7 slides within the groove 9. After the fixing screw 8 moves out from the moving hole 10, a positioning nut 11 is provided on it. By tightening the positioning nut 11, the adjusted connecting plate 2 can be positioned to ensure its stability. When it is necessary to slide the connecting plate 2, simply loosen the positioning nut 11 so that the fixing screw 8 slides along the length direction of the moving hole 10.

[0022] The slider 7 and the connecting plate 2 are integrally formed to ensure structural strength. The fixing screw 8 is detachably mounted on the slider 7, preferably with a threaded hole on the slider 7, and the fixing screw 8 is threaded into the threaded hole. This detachable mounting facilitates disassembly, allowing the slider 7 to be removed from the groove 9, which is convenient for manufacturing and subsequent replacement of parts, reducing maintenance costs. Furthermore, in this embodiment, the bottom of the groove 9 is open, meaning the fixing angle plate 1 at the bottom of the groove 9 is open. This ensures that after the slider 7 is installed in the groove 9, it contacts the surface of the steel column 5, increasing the contact area between the assembly tool and the steel column 5, ensuring the stability of the connection between the tool and the steel column 5, and improving its load-bearing capacity.

[0023] In use, this invention first involves simply installing two fixed angle plates 1 diagonally above the already installed bottom steel column 5 without tightening. Then, a hoisting device lifts the steel column 5 to be installed above the already installed steel column 5. The hoisting device is controlled to lower the steel column 5 along the space between the two fixed angle plates 1, making contact with the already installed steel column 5 below. Finally, the locking nuts 4 on the connecting screws 3 are tightened to secure the two fixed angle plates 1, thus completing the temporary fixed connection between the upper and lower steel column sections 5. Due to the constraint of the fixed angle plates 1, the two sized steel column sections 5 will achieve precise alignment. At this point, welding is first performed at the joint of the two steel column sections 5 through the operating space formed between the two connecting plates 2 on each side. After welding, the two steel column sections 5 achieve a preliminary fixed connection. Then, the fixed angle plates 1 are removed, and welding is performed on the area covered by the fixed angle plates 1. The structure is simple, the operation is convenient, it can be reused multiple times, and it is highly practical.
