Description

Technical Field

[0001] This utility model relates to the field of steel structure connection, specifically to an adjustable steel structure connection device. Background Technology

[0002] I-beams are widely used in construction, bridges, machinery, and energy fields due to their advantages such as structural stability, high load-bearing capacity, and low manufacturing cost. They play a particularly important role in high-rise buildings, bridge main beams, and heavy equipment supports. Their good strength and durability enable them to maintain stability for extended periods even in complex working environments, making them an indispensable material in modern engineering construction.

[0003] Straight connections of I-beams are typically achieved through welding, bolting, or riveting. Welding and riveting offer relatively strong connections but are not conducive to disassembly. When bolting I-beams, uneven pressure application is a common defect. At the connection point between the bolt and the I-beam, the contact surface is the threaded surface, leading to uneven stress distribution. This uneven pressure distribution can cause localized stress concentration at the connection, thus affecting the overall structural stability and load-bearing capacity. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] First embodiment:

[0025] See Figures 1-4 As shown, this utility model provides an adjustable steel structure connection device, in which two I-beams 7 extend along the same straight line, and the top frame 1 and the bottom frame 3 are located on both sides of the I-beams 7 respectively, and the connection and clamping of the two I-beams 7 are achieved through the top frame 1 and the bottom frame 3;

[0026] Specifically, the inner top surfaces of the top frame 1 and the bottom frame 3 are provided with pressure plates 5 corresponding to the I-beams 7, wherein the pressure plates 5 on the bottom frame 3 are threadedly connected to the bottom frame 3 via threaded rods 6;

[0027] The top frame 1 is provided with screw rods 2 on both sides, and the base frame 3 is provided with mounting holes 301 corresponding to the screw rods 2. Nuts are threaded on the outside of the screw rods 2 for fixing the top frame 1 and the base frame 3.

[0028] During the specific fixing process, the top frame 1 is placed above the I-shaped steel 7, so that the pressure plate 5 corresponds to the concave position on the I-shaped steel 7. At this time, the bottom surface of the pressure plate 5 on the top frame 1 is in contact with the surface of the I-shaped steel 7. The bottom frame 3 is placed below the I-shaped steel 7, so that the mounting hole 301 corresponds to the screw rod 2. The screw rod 2 passes through the mounting hole 301 and is fixed by the nut, thus connecting and fixing the top frame 1 and the bottom frame 3. At this time, the inner walls of the top frame 1 and the screw rod 2 are in contact with the upper and lower surfaces of the I-shaped steel 7, respectively, thus pressing the two I-shaped steel 7 together. Furthermore, by screwing the threaded rod 6, the pressure plate 5 on the top surface of the threaded rod 6 corresponds to the concave position at the bottom of the I-shaped steel 7. The two concave positions of the I-shaped steel 7 can be pressed by the two pressure plates 5. The top frame 1 and the bottom frame 3 press the upper and lower surfaces of the I-shaped steel 7 respectively, resulting in a good pressing effect on the I-shaped steel 7.

[0029] In a preferred embodiment, both the top frame 1 and the bottom frame 3 are door-shaped structures, with their open ends correspondingly arranged.

[0030] Furthermore, the number of screw rods 2 on each side of the top frame 1 is not less than two. When there are two screw rods 2, the two screw rods 2 correspond to two I-beams 7 respectively. When there are more than two screw rods 2, fixation can be achieved by multiple screw rods 2, which can improve the stability of the connection between the top frame 1 and the base frame 3. In addition, the screw rod 2 is rotatably connected to the top frame 1, and the mounting hole 301 penetrates to the outer wall of the base frame 3. After the screw rod 2 rotates, it can be inserted into the mounting hole 301 through the side of the mounting hole 301. The screw rod 2 is connected by a nut, which can assist in the installation of the screw rod 2 and better fix the screw rod 2 and the mounting hole 301.

[0031] The second embodiment differs from the first embodiment in that:

[0032] Both the top frame 1 and the bottom frame 3 are provided with side screws 4 on their side walls. When the top frame 1 and the bottom frame 3 are set on the outside of the I-beam 7, the inner end of the side screw 4 can be made to contact the outer wall of the I-beam 7 by screwing the side screw 4. With this setting, it is not necessary to use a top frame 1 and a bottom frame 3 with a specific inner wall size according to the size of the I-beam 7, which greatly improves the flexibility of the top frame 1 and the bottom frame 3.

[0033] Furthermore, the number of side bolts 4 on the side wall of the top frame 1 is not less than two, and each corresponds to one of the two I-beams 7, which can improve the fixing stability of the I-beams 7 through multiple side bolts 4;

[0034] The third embodiment differs from the first embodiment in that:

[0035] The pressure plate 5 is concave, and its open side corresponds to the concave position of the I-beam 7. The concave position of the surface of the pressure plate 5 is exactly aligned with the gap between the two I-beams 7. The two convex positions on the pressure plate 5 correspond to the two I-beams 7, thus achieving the pressing of the two I-beams 7.

[0036] In addition, when installing the pressure plate 5 on the base frame 3, the pressure plate 5 is rotatably connected to the threaded rod 6, and the threaded rod 6 is threadedly connected to the base frame 3. The movable end of the threaded rod 6 is provided with a wrench groove. With this setting, the wrench groove can be an internal hexagon or other polygons. After the wrench is inserted into the wrench groove, the threaded rod 6 is rotated. By utilizing the threaded engagement between the threaded rod 6 and the base frame 3, the height of the pressure plate 5 can be adjusted, so that the pressure plate 5 moves toward the I-beam 7, and the two I-beams 7 can be pressed together by the pressure plate 5.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
