Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure trusses, and in particular relates to a steel structure truss. Background Art

[0002] The truss is mainly composed of a variety of different modular truss components or elements. It is usually a rigid structure used for object construction. During the truss construction process, the truss length is often extended to meet site needs, and other tools are needed to assist in the connection and extension between the trusses. The extension and fixation between the trusses is also an important point to maintain a stable connection of the trusses.

[0003] In the Chinese patent with publication number CN 219710549 U, it is mentioned that by inserting one end of a solid round rod into the inner cavity of an installation inner slot, the threaded rod and the built-in threaded groove are threadedly connected. When the extension rod is inserted into the inner cavity of the inner slot, the outer wall of the inner slot will be inserted into the inner cavity of the embedded groove, and the penetrating groove and the corresponding groove are fixed and installed using fixing nails. The threaded connection between the threaded rod and the built-in threaded groove and the fixation of the fixing nails can improve the stability of the connection between the truss and the solid round rod.

[0004] However, the solid round rods and the trusses are connected in a plug-in manner. During long-term use, the wear of the solid round rods and the connecting holes in the truss may cause the connection between the solid round rods and the connecting holes in the truss to become loose, resulting in the solid round rods being prone to shaking during use of the truss. The harsh sound generated during the shaking process affects the work experience of people around, and the loose solid round rods have poor safety performance. Therefore, the present application proposes a steel structure truss that can quickly connect to the support rods in the truss, and the components inside the truss are tightly connected and not easy to shake.

[0007] The truss support rod is provided with a first slot at a position corresponding to the groove, and the protrusion is provided with a second slot, the first slot is aligned with the second slot, and the insertion rod penetrates the first slot and is inserted into the second slot;

[0008] It also includes a protective sleeve, and the connecting piece is provided with two threaded parts, and the two threaded parts are respectively threadedly connected to the two protective sleeves;

[0009] The insertion rod comprises a rod portion and a round cap.

[0010] Preferably, a slide groove is provided on the connecting piece at an area between the threaded portion and the center line of the connecting piece, the protective sleeve is inserted into the slide groove, and the protective sleeve is slidably connected to the slide groove.

[0011] Preferably, a sealing groove is provided at the portion of the protective sleeve inserted into the slide groove, an inner sealing gasket is installed in the sealing groove, and the inner ring of the inner sealing gasket fits the outer wall of the slide groove.
