AI Technical Summary
The existing connection structure between H-shaped steel and the beam extension arm is difficult to achieve a close fit between the H-shaped steel and the inner wall of the extension arm, resulting in poor reinforcement effect.
The H-shaped steel and the extending arm are connected by long-hand bolts, and through a tightening structure, including a bidirectional threaded rod and a screw pipe, the L-shaped steel plate and angle iron slide, making the inner wall of the extending arm more fit with the H-shaped steel surface.
The tight fit between the H-shaped steel and the inner wall of the extending arm is achieved, which significantly improves the reinforcement effect, and enhances the stability and fastening force of the connection through the setting of the rubber pad ring and the expanded iron sheet.

Technical Field
[0001] The utility model belongs to the technical field of steel structures, and particularly relates to a connection structure of an H-shaped steel on a crossbeam extension arm. Background Technique
[0002] The H-shaped steel is an economic section and high-efficiency profile, which is commonly used in large buildings requiring large load-bearing capacity and good section stability, such as crossbeams, ships, hoisting and transportation machinery, brackets, foundation piles, etc.
[0003] The H-shaped steel is usually fixedly connected to the extension arm of the crossbeam by bolts. In order to make the fit between the H-shaped steel and the inner wall of the extension arm closer to achieve a better reinforcement effect, a connection structure of the H-shaped steel on the crossbeam extension arm is designed. This structure uses long-shank bolts to reinforce the connection between the H-shaped steel and the extension arm, and the long-shank bolts fix the angle iron and the L-shaped steel plate at opposite positions of the extension arm. At the same time, the action of the tight support structure makes the inner wall of the extension arm and the surface of the H-shaped steel fit more fully, so that the fit between the H-shaped steel and the inner wall of the extension arm can be closer to achieve a better reinforcement effect. Content of the Utility Model
[0004] The purpose of the utility model is to provide a connection structure of an H-shaped steel on a crossbeam extension arm, which has the purpose of making the fit between the H-shaped steel and the inner wall of the extension arm closer to achieve a better reinforcement effect, so as to solve the above-mentioned background technical problems.
[0005] The technical solution for the utility model to solve the above technical problems is as follows: A connection structure of an H-shaped steel on a crossbeam extension arm, which includes extension arms welded to both sides of the bottom of the crossbeam: The inner walls of both extension arms are fixedly connected with H-shaped steels by bolts, long-shank bolts are threadedly connected between the H-shaped steels and the extension arms, angle irons are fixedly connected between the two H-shaped steels by long-shank bolts, L-shaped steel plates are rotatably connected to the tops of the opposite sides of the two angle irons, and a tight support structure is arranged between the two L-shaped steel plates.
[0006] Preferably, the tight support structure includes rectangular grooves opened on the inner walls of the L-shaped steel plates, and screw pipes are slidably connected to the inner cavities of both L-shaped steel plates.
[0007] Preferably, a bidirectional threaded rod is commonly threadedly connected between the screw pipes, and a hexagonal iron is fixedly connected to the center of the bidirectional threaded rod.
[0008] Preferably, rectangular blocks are welded to the opposite ends of the screw pipes, and the surfaces of the rectangular blocks are slidably connected to the inner cavities of the rectangular grooves.
[0009] Preferably, the bottom end of the long-shank bolt penetrates into the inner cavity of the angle iron and is threadedly connected with a nut, and a rubber gasket ring is slidably connected to the surface of the long-shank bolt.
[0010] Preferably, the rubber gasket ring is located between the long shank bolt and the inner wall of the H-shaped steel, and widened surface iron sheets are welded to the bottoms of the opposite sides of the two angle irons.
[0011] The beneficial effects of the present utility model are as follows:
[0012] 1. By rotation, the bidirectional threaded rod rotates in the inner cavity of the screw tube. At this time, under the action of the thread, the screw tube pushes the L-shaped steel plate and the angle iron to slide away from each other, so that the inner wall of the extension arm fits more fully with the surface of the H-shaped steel, and thus the fitting between the H-shaped steel and the inner wall of the extension arm can be made closer to achieve a better reinforcement effect;
[0013] 2. Through the setting of the rubber gasket ring, the long shank bolt can be protected by being cushioned from the inner wall of the H-shaped steel, and an auxiliary tightening force can be obtained between the long shank bolt and the inner wall of the H-shaped steel, enabling the connection between the long shank bolt and the H-shaped steel to be more fixed;
[0014] 3. Through the setting of the widened surface iron sheet, the contact area between the L-shaped steel plate and the angle iron can be increased, and it can be more stable when the L-shaped steel plate applies a tightening force to the angle iron. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle: When the utility model is in use, the user fixes the angle iron 5 to the opposite sides of the two telescopic arms 2 through the long handle bolt 4, then rotates the L-shaped steel plate 6 to deflect the L-shaped steel plate 6, and then screws the nut 8 to make the connections between the angle iron 5 and the H-shaped steel 3 and the telescopic arm 2 more fixed.
