TECHNICAL FIELD

[0001] The application relates to the technical field of steel trusses, in particular to a high-efficiency assembled steel truss. BACKGROUND

[0002] In the field of building steel structures, traditional steel trusses are mostly assembled by on-site welding or bolt connection. This traditional method not only consumes time and effort, but is also greatly affected by weather conditions, which can easily lead to delays in construction progress and unstable quality.

[0003] In recent years, with the development of prefabricated buildings, more and more research has focused on how to improve the prefabrication rate and assembly efficiency of steel trusses. However, although existing prefabricated steel trusses have improved construction speed to some extent, there are still some deficiencies in node connection strength and overall stability. To solve the above problems, a high-efficiency assembled steel truss is proposed. CONTENT OF THE INVENTION

[0011] Through the above scheme, the relationship between the connection piece and the work-shaped groove is limited, and the relationship between the connection hole and the reserved hole is also limited, so that more efficient assembly can be realized.

[0012] Further, one end of the connection piece is inserted into one end of the standard segment through the work-shaped groove and the reserved hole, and the connection piece is positioned at one end of the standard segment through the two corresponding first double-headed studs and the first locking nuts.

[0013] Through the above scheme, the connection piece can stably connect two standard segments, and the first double-headed stud and the first locking nut can quickly and stably connect two standard segments through the connection piece.

[0014] Further, the size value of the work-shaped block corresponds to the size value of the work-shaped groove, and the diameter value and position of the first fixing hole correspond to the diameter value and position of the reserved hole.

[0015] Through the above scheme, the size values of the work-shaped block and the work-shaped groove are limited, thereby facilitating the splicing work between the standard segment and the secondary beam body.

[0016] Further, the fixing mechanism comprises an L-shaped fixing piece, and four third fixing holes are arranged on the outer surface of the L-shaped fixing piece.

[0017] Through the above scheme, the third fixing hole opened can quickly position the L-shaped fixing piece between the standard segment and the secondary beam body, realizing the effect of efficient assembly.

[0020] Further, the inner wall of the four third fixing holes is respectively provided with two fixing bolts and two second double-headed studs, and the two ends of each second double-headed stud are provided with a second locking nut.

[0021] Through the above scheme, the fixing bolt can position the L-shaped fixing piece on the secondary beam body, and the second double-headed stud and the second locking nut can position the L-shaped fixing piece on the standard segment, thereby further improving the stability of the connection between the main beam assembly and the secondary beam assembly.

Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the application.

[0033] Please refer to Figure 1 , Figure 2 and Figure 4 The high-efficiency assembled steel truss in the embodiment includes a main beam assembly 1, a connecting mechanism 2, a secondary beam assembly 3 and a fixing mechanism 4. Two main beam assemblies 1 are connected through the connecting mechanism 2, and the secondary beam assembly 3 is connected with the main beam assembly 1 through the fixing mechanism 4. The above description can achieve the effect of high-efficiency assembly. The main beam assembly 1 includes a standard segment 101. The standard segment 101 is made of Q345B steel material, has good mechanical properties and corrosion resistance. Channel grooves 102 are arranged at both ends of the standard segment 101. Four through reserved holes 103 are arranged on both sides of the outer surface of the standard segment 101. The reserved holes 103 penetrate the corresponding channel grooves 102. The main beam can be obtained by assembling a plurality of standard segments 101. The standard segment 101 can be mass-produced. The channel grooves 102 and the reserved holes 103 are arranged at specified positions when the standard segment 101 is produced, so that the prefabrication of modularization is realized, and the high-efficiency assembled steel truss is more practical.

[0034] Please refer to Figure 1 , Figure 4 and Figure 5 , the connecting mechanism 2 comprises a connecting piece 201 and two rubber pads 202 fixedly connected to the surface of the connecting piece 201. The rubber pads 202 can improve the anti-vibration effect of the connecting piece 201.

The diameter value and position of the connecting hole 204 correspond to the diameter value and position of the reserved hole 103. By limiting the relationship between the connecting piece 201 and the I-shaped groove 102 and the relationship between the connecting hole 204 and the reserved hole 103, more efficient splicing effect can be achieved. The first double-headed studs 205 are installed on the inner wall of each connecting hole 204. The first locking nuts 206 are installed on the two ends of each first double-headed stud 205.

Two first fixing holes 303 are formed in the two sides of the outer surface of the I-shaped block 302. The diameter value and position of the first fixing hole 303 correspond to the diameter value and position of the reserved hole 103.
