Description

Technical Field

[0001] The utility model relates to the field of steel structure connection, in particular to a firmly connected steel structure connection fixing device. Background Art

[0002] Steel structure connection refers to the mutual connection between steel structure members or components. Steel structure connection is usually made by weld connection, bolt connection or rivet connection. Bolt connection is divided into ordinary bolt connection and high-strength bolt connection.

[0003] After searching, the Chinese patent "A steel structure connection and fixing device" with the authorization announcement number "CN 216892828U" was found. This patented technology realizes the vertical connection and fixation between steel sections through pull pieces and supports, which not only reduces the number of openings in the steel sections and improves the structural strength of the steel sections, but also increases the connection area between the steel sections. The horizontal steel sections are firmly fixed in an embracing manner, and the pull pieces and supports are simply and reliably connected to the vertical steel sections, which improves the overall strength and stability, making the steel structure connection more reliable and safe.

[0004] Although the patented technology solves the problem that the connection force between H-shaped steels mainly relies on the tension of bolts, the stress points are small and easy to deform, and the H-shaped steels have a large number of openings, which affects the structural strength, the patented technology requires the use of a crane or a crane to lift the horizontal steel for assembly when fixing the two steel sections. During the assembly process, due to foundation stability, strong wind influence, load distribution and operational factors, the horizontal steel section is difficult to maintain stability, resulting in difficulty in assembling the two steel sections. Therefore, a firmly connected steel structure connection and fixing device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a firmly connected steel structure connection and fixing device in order to solve the above-mentioned problem, thereby improving the problem that during the assembly process, the horizontal steel sections are difficult to maintain stability due to foundation stability, strong wind influence, load distribution and operational factors, resulting in difficulty in assembly between two steel sections.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a firmly connected steel structure connection and fixing device, comprising a transverse steel section; a positioning assembly, wherein the positioning assembly comprises a positioning block fixedly connected to one side of the transverse steel section, one side of the positioning block is provided with four positioning grooves, the positioning block is provided with four rectangular grooves which are axially symmetrically distributed relative to the axis of the transverse steel section, a spring is arranged in the rectangular groove, and the other end of the spring is fixedly connected to a limit plate located in the rectangular groove.

[0007] Preferably, a vertical steel section is provided on one side of the transverse steel section, and the transverse steel section and the vertical steel section are connected together by a positioning assembly to facilitate the assembly of the steel section.

[0008] Preferably, the same threaded hole is opened in the transverse steel section and the vertical steel section, and the threaded hole is connected with an auxiliary positioning bolt, which can position the transverse steel section and the vertical steel section by the auxiliary positioning assembly. When the positioning assembly is installed, the threaded holes opened in the transverse steel section and the vertical steel section correspond to each other, and the auxiliary positioning bolts are installed in the threaded holes, thereby further limiting the transverse steel section and the vertical steel section, so as to facilitate the subsequent assembly work.

[0009] Preferably, four positioning columns are fixedly connected to the inner side of the vertical steel section, and the four positioning columns correspond to four positioning grooves respectively. This can limit the transverse steel section through the positioning columns, thereby ensuring the stability of the transverse steel section and the vertical steel section when connected.

[0010] Preferably, two rectangular openings are opened on one side of the vertical steel section, and the positioning block is connected to the vertical steel section through the rectangular opening, which facilitates the insertion of the positioning block on one side of the transverse steel section into the vertical steel section and can limit the transverse steel section.

[0011] Preferably, limiting grooves are provided at both upper and lower ends of the inner side of the rectangular opening, and the four limiting plates are respectively arranged corresponding to the four limiting grooves, which can play a positioning role for the transverse steel section and the vertical steel section. When the limiting plates are inserted into the limiting grooves, the threaded holes in the transverse steel section will correspond to the threaded holes in the vertical steel section, so as to facilitate the installation of auxiliary positioning bolts.

[0012] Preferably, a lower fixing plate is provided at the bottom of the transverse steel section, and one side of the lower fixing plate is connected to one side of the vertical steel section, which can fix the transverse steel section to ensure the stability and safety of the entire steel section structure.

[0013] Preferably, an upper fixing plate is provided on the top of the transverse steel section, and one side of the upper fixing plate is connected to one side of the vertical steel section, which can fix the transverse steel section and reduce the vertical stress of the transverse steel section to prevent the transverse steel section from being stretched and deformed.

[0014] The beneficial effects of the utility model are:

[0015] 1. Press the limit plate to move it into the rectangular groove, and then insert the positioning block into the vertical steel section through the rectangular opening. The positioning column in the vertical steel section will be inserted into the positioning groove on one side of the positioning block. At the same time, the limit plate in the rectangular groove will correspond to the limit groove. At this time, the limit plate is moved into the limit groove by the elastic stress of the spring, thereby solving the problem that the horizontal steel section is difficult to maintain stability, resulting in the difficulty of assembly between the two steel sections;

[0016] 2. After the positioning assembly is installed, the threaded holes in the horizontal and vertical steel sections correspond to each other, and the auxiliary positioning bolts are installed in the threaded holes to further limit the horizontal and vertical steel sections for later assembly work.
