Description

Technical Field

[0001] This utility model belongs to the field of positioning fixtures, and specifically relates to a quick positioning fixture for inclined docking of steel plates with variable wall thickness. Background Technology

[0002] In current bridge construction projects, due to structural design characteristics and considerations such as saving steel consumption, some bridge designs use thick-walled steel plates as the connecting material between the cable lugs and the cables, while the parts connected to the bridge structure use thin-walled steel plates.

[0003] However, in current practical applications, the relatively large cross-section of the bridge main structure results in excessively long cable lugs extending from the main structure. Strict restrictions on width and height for road transport further complicate this process. To accommodate these transport conditions, the cable lugs are cut at the wall thickness transition points and then assembled on-site. This process is particularly complex because the cable lugs typically have a certain angle of inclination and involve the joining of steel plates of varying thicknesses. On-site installation suffers from difficulties in adjusting the installation angle, complex joining of plates with varying wall thicknesses, and low installation efficiency.

[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 quick positioning fixture for inclined docking of steel plates with variable wall thickness. It has a simple structure and reasonable design, and can be used for construction such as bridge cable lugs and inclined docking of steel plates with variable wall thickness, so as to meet the needs of inclined docking of different wall thicknesses. It is easy to operate and can be reused.

[0006] Technical Solution: A quick-positioning fixture for inclined butt joint of variable wall thickness steel plates includes a set of first angle steels, a set of adjusting components, a fixture, a limiting baffle, a top supporting angle steel, a first fastener, and a second angle steel. The first angle steels respectively abut against one side of a thin-walled steel plate and a thick-walled steel plate, with the thick-walled steel plate located below the thin-walled steel plate. Adjusting components are mounted on the first angle steels. The fixture is located on the outer sides of the thick-walled steel plate and the first angle steels, clamping them together. One end of the limiting baffle is connected to the first angle steel, and the other end is located on the outer side of the thin-walled steel plate. The top supporting angle steel is connected to the first angle steel via the first fastener. The second angle steel is located between the two first angle steels. This application has a simple structure, reasonable design, small footprint, and can adaptively adjust to any desired positioning angle.

[0007] Furthermore, the clamp is C-shaped and made of steel. The steel used in this application possesses high tensile strength and hardness, and the C-shaped clamp can withstand significant forces without easily deforming or being damaged, making it suitable for fixing or clamping heavy workpieces.

[0008] Furthermore, the clamp is welded to the outer side of the first angle steel flange. By placing the clamp on the outer side of the angle steel flange, this application can distribute the force more evenly on the angle steel, which helps to reduce stress concentration points and avoid material fatigue or damage caused by excessive local stress.

[0009] Furthermore, the limiting baffle is L-shaped and made of steel. The steel used in this application possesses high tensile strength and hardness, and the L-shaped clamp can be applied to steel plates of different thicknesses.

[0010] Furthermore, the limiting baffle is welded to the outer flange of the inclined angle steel. The limiting baffle of this application can serve a limiting and fixing function at the edge.

[0011] Furthermore, the adjusting component includes a screw and a nut. The nut is welded to the first angle steel, and the screw is screwed into the nut, abutting against the thin-walled steel plate and the thick-walled steel plate respectively. This application utilizes the threaded connection formed by the screw and nut to provide strong tensile strength. At the same time, since the nut is directly welded to the angle steel, this further enhances the stability of the entire connection structure.

[0012] Furthermore, the second angle steel is connected to the connecting plate via a second fastener. This fastener connection allows for easy disassembly or reassembly without damaging the materials.

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

[0014] 1. The quick positioning clamp for inclined docking of steel plates with varying wall thickness described in this utility model has a simple structure and reasonable design. By setting steel plate clamps and fasteners on the supporting angle steel and connecting them with the thin-walled steel plate, the inclined supporting angle steel serves as a sliding limiting surface to slide and install the thick-walled steel plate, which plays a role in limiting the inclined positioning of the docking steel plates in terms of structure.

[0015] 2. This application has a wide range of applications and can be used for the construction of bridge cable lugs, inclined joints of steel plates with varying wall thicknesses, etc., so that it can meet the needs of inclined joints with different wall thicknesses. It is simple to operate and can be reused, thus better meeting the needs of construction. Attached Figure Description
