Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of H-shaped steel connection tools, and specifically to a right-angle connection device. Background Art
[0002] In steel structure buildings and projects, the H-shaped steel, named after its cross-sectional shape similar to the English letter "H", is a highly efficient and economical section steel. It is widely used in beam and column members of industrial and civil structures, as well as in multiple fields such as underground engineering, petrochemical industry, electric power, bridges, ships, and machinery manufacturing. With its excellent mechanical properties and reasonable cross-sectional design, the H-shaped steel has the advantages of strong bending resistance, simple construction, light structural weight, and cost savings, and has become an important part of modern steel structure buildings.
[0003] Since the H-shaped steel is long and strip-shaped, when connecting two H-shaped steels, especially when the ends of two H-shaped steels are perpendicularly connected to each other, there is always a gap at the ends of the two H-shaped steels. The traditional connection method is to directly fix and install the H-shaped steel on the corresponding plate body, leaving this gap area as it is and not using a connection device to connect the gap area. At this time, there will be a lack of connecting parts at the corner parts of two adjacent H-shaped steels, which not only affects its stability but also affects the matching accuracy between the two H-shaped steels. In view of this, we have proposed a right-angle connection device. Summary of the Utility Model

[0026] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a right-angle connection device, including a connection component 2, the connection component 2 is used to be connected at the corner part of two H-shaped steel bodies 1 spliced perpendicularly to each other. The connection component 2 includes two symmetrically arranged flat plates 20 up and down. A cross plate 21 is fixedly installed between the two flat plates 20. There are four welding grooves 22 between the cross plate 21 and the two flat plates 20. Rectangular plates 23 are fixedly installed on the bottom and top walls of the welding grooves 22 on the left and right sides. An end plate 231 is fixedly installed at the end of each rectangular plate 23. A first compression plate 24 is fixedly installed between the two end plates 231 distributed up and down. Fixed plates 26 are fixedly installed on the bottom and top walls of the welding groove 22 at the middle position of the front side. Top plates 27 are fixedly installed on the front two side surfaces of each fixed plate 26. A second compression plate 28 is fixedly installed between the two top plates 27 distributed up and down. There is a plate insertion gap 29 between the second compression plate 28 and the first compression plate 24 on the adjacent same side. The end plates 231 and the top plates 27 are slidably connected to the upper and lower side plates of the H-shaped steel body 1. After the end of the steel body 1 is inserted between the end plates 231 and the top plates 27, the end plates 231 and the top plates 27 can abut against the inner surface of the H-shaped steel body 1, thereby realizing the connection and assembly operations.
[0027] In this embodiment, the top surface of the upper flat plate 20 and the bottom surface of the lower flat plate 20 are respectively in the same plane as the upper surface and the lower surface of the H-shaped steel body 1, making the overall surface smoother and achieving an aesthetic effect.
[0028] Specifically, the vertical plate body 10 of the H-shaped steel body 1 can be inserted into the plate insertion gap 29 and is in plug-in fit with the plate insertion gap 29. The size of the vertical plate body 10 is adapted to the size of the plate insertion gap 29. The first compression plate 24 and the corresponding second compression plate 28 are respectively located on both sides of the corresponding vertical plate body 10, thereby realizing the connection operation of normal insertion.
[0029] Furthermore, through holes are provided with first bolt holes 11 on the upper and lower surfaces of the end plate body of the H-shaped steel body 1. Through holes are provided with second bolt holes 271 on the end plates 231 and the top plates 27.

[0030] In addition, two symmetrically arranged cross bars 25 are fixedly installed between the upper and lower corresponding rectangular plates 23 and end plates 231. The cross section of the cross bar 25 is in an "X" shape. The cross bar 25 can provide compressive support between the rectangular plate 23 and the end plate 231. A compressive column 262 is fixedly installed between the upper and lower fixing plates 26. The compressive column 262 is a solid columnar structure, and the compressive column 262 can provide compressive support for the upper and lower fixing plates 26.
[0031] It should be noted that a cross compressive bar 261 is fixedly installed between the upper and lower fixing plates 26. The end of the cross compressive bar 261 is located at a position close to the side of the fixing plate 26 to perform the compressive support operation on the fixing plate 26.
[0032] When the right-angle connection device of the present utility model is in use, the two H-shaped steel bodies 1 are normally joined at a right angle, ensuring that the end plates of the two H-shaped steel bodies 1 are abutted together. Then, the end plate 231 and the top plate 27 are aligned with the left and right sides of the vertical plate 10 on the H-shaped steel body 1 and inserted into the H-shaped steel body 1. At the same time, ensure that the vertical plate 10 is inserted into the plate clamping gap 29. At this time, the end plate 231 and the top plate 27 are abutted against the inner surfaces of the upper and lower plates of the H-shaped steel body 1 to complete the support operation. Finally, the H-shaped steel body 1 is fixed to the end plate 231 and the top plate 27 with fastening bolts to complete the fixing operation.
