Description

Technical Field

[0001] This utility model belongs to the field of engineering construction technology, and specifically relates to a simple handheld handle for assisting in the installation of connecting plates. Background Technology

[0002] In the current field of bridge construction, bolted steel bridges are increasingly widely used. The design of such bridges not only needs to ensure that the structure can withstand huge loads, but also places higher demands on the connecting components. As the load-bearing capacity of bridges increases, the size and weight of their connecting plates also increase significantly. These large connecting plates are usually assembled by bolting rather than welding during the manufacturing process, mainly to avoid the impact of thermal stress generated during welding on material properties and the possible structural damage.

[0003] However, this design choice also brings new challenges, especially during the handling and installation phases. Since the connecting plates themselves cannot be welded with lifting lugs, additional welding would introduce unpredictable stress distributions into the already precisely calculated structure, potentially leading to material fatigue or structural weakening. Therefore, the traditional method of adding lifting points through welding is no longer applicable. This makes transporting large, heavy connecting plates to the construction site and subsequent installation and positioning significantly difficult, increasing construction complexity and risk.

[0004] Therefore, the above situation urgently needs to be addressed. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a simple hand-held handle for assisting in the installation of connecting plates. As a hand-held handle for installing connecting plates, it can be used in the construction of bridge connecting plates, steel frame connecting plates, etc., so as to meet the needs of installing connecting plates. It is simple to operate and can be reused, thus better meeting the needs of construction.

[0006] Technical Solution: A simple handheld handle for assisting in the installation of a connecting plate includes an angle steel, a steel plate, a handle, and a bolt; an angle steel is provided on one side of the steel plate, and a bolt is provided on the other side of the steel plate, with the bolt perpendicularly inserted into the steel plate; the handle is attached to the bolt. This application features a simple structure and reasonable design, ensuring its lightweight and compact design, which not only facilitates prefabrication but also greatly simplifies the carrying and transportation process. Due to the absence of large components, it also reduces the need for storage space.

[0007] Furthermore, the bolt includes a nut and a threaded rod, with the handle abutting between the nut and the threaded rod; the nut is welded to the side of the steel plate not near the angle steel. By welding the nut to the steel plate, rather than installing it directly near the angle steel, this application avoids structural instability or deformation caused by stress concentration between the angle steel and the steel plate; the handle abutting between the nut and the threaded rod provides additional support when tightening the bolt.

[0008] Furthermore, a connecting plate is placed between the steel plate and the angle steel with a pre-existing gap, and multiple second holes are evenly distributed on the connecting plate. This design allows for flexible adjustment of the position and size of the connecting plate according to actual conditions, adapting to different engineering needs.

[0009] Furthermore, a first hole is provided in the steel plate, and the first hole has the same diameter as a second hole in the connecting plate. The first hole and the second hole are connected by bolts.

[0010] Furthermore, the thickness of the steel plate is at least 10 mm. The increased steel plate thickness in this application significantly improves the overall strength and rigidity of the structure, ensuring its stability even under heavy loads.

[0011] Furthermore, the handle is made of metal and is in the shape of a hollow cylindrical tube. The handle in this application is made of metal, generally steel. Handles made of steel possess extremely high strength and durability, and can withstand significant mechanical stress and impact.

[0012] Furthermore, the handle is at least 60mm long. The handle length described in this application provides better leverage, making it easier to apply force, and a suitable handle length can be selected according to the actual construction situation.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. The present application proposes a simple handheld handle for assisting in the installation of connecting plates, which can be used in the construction of bridge connecting plates, steel frame connecting plates, etc., so as to meet the needs of connecting plate installation. It is easy to operate and can be reused, thus better meeting the needs of construction.

[0015] 2. The present application proposes a simple handheld handle for assisting in the installation of a connecting plate, which aims to provide a simplified structure and convenient operation solution, which not only facilitates quick disassembly and installation, but also greatly improves portability.

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] This embodiment describes a simple handheld handle for assisting in the installation of a connecting plate. Please refer to [reference needed]. Figure 1 As shown, it includes an angle steel 1, a steel plate 2, a handle 3, and a bolt 4; the angle steel 1 is provided on one side of the steel plate 2, and the bolt 4 is provided on the other side of the steel plate 2, with the bolt 4 perpendicularly inserted into the steel plate 2; the handle 3 is sleeved on the bolt 4. The handle 3 is made of metal material and is in the shape of a hollow round tube; the length of the handle 3 is at least 60mm.

[0023] Please refer to Figure 2 As shown, the bolt 4 includes a nut 401 and a threaded rod 402, and the handle 3 abuts against the nut 401 and the threaded rod 402; the nut 401 is welded to the side of the steel plate 2 that is not near the angle steel 1. A connecting plate 5 is placed between the steel plate 2 and the angle steel 1 with a pre-reserved gap, and multiple second holes 501 are evenly distributed on the connecting plate 5. The thickness of the steel plate 2 is at least 10mm.

[0024] Please refer to Figure 3 As shown, the steel plate 2 has a first hole 201, and the first hole 201 has the same diameter as the second hole 501 on the connecting plate 5.

[0025] A specific embodiment of the handheld simple handle for assisting in the installation of the connecting plate includes:

[0026] Step S1: A first hole 201 is provided in the steel plate 2. The diameter of the first hole 201 is the same as the diameter of the second hole 501 in the connecting plate 5. Multiple components can be made for matching according to the different diameters of the second hole 501.

[0027] Step S2: Weld angle steel 1 to one side of steel plate 2 according to the position. The net distance between the flange of angle steel 1 and steel plate 2 should be slightly greater than the thickness of connecting plate 5. Multiple components can be made for matching according to the different thicknesses of connecting plate 5.

[0028] Step S3: Weld the nut 401 of bolt 4 to the front of steel plate 2. The diameter of bolt 4 screw 402 should be slightly smaller than the hole diameter of steel plate 2, and the length of bolt 4 screw 402 should be suitable for hand gripping.

[0029] Step S4: Insert the handle 3 between the nut 401 and the screw 402 of the bolt 4. The diameter of the handle 3 should be smaller than the diameter of the nut of the bolt 4 to prevent the handle 3 from slipping off, making it easy to hold and adjust the tilt angle of the connecting plate 5.

[0030] Step S5: Align the assembled handle 3 assembly with the hole in the connecting plate 5, tighten the bolt 4, so that the screw 402 of the bolt 4 passes through the hole in the connecting plate 5 and presses against the flange of the angle steel 1.

[0031] Step S6: For the connecting plate 5 which is large in size and heavy in weight, multiple hand handles 3 can be set to facilitate manual transportation and installation.

[0032] The above steps complete the installation.
