[0001] The utility model relates to the field of steel structure support trusses, in particular to a high-safety torsion-resistant steel structure support truss. Background Technique

[0002] A steel truss refers to a truss made of steel. In industrial and civil buildings, roof structures, crane beams, bridges, and hydraulic gates, etc., steel trusses are commonly used as the main load-bearing members. Various types of tower structures, such as mast towers, television towers, and transmission line towers, etc., are commonly composed of three-sided, four-sided or multi-sided planar trusses to form a space steel truss.

[0003] The existing steel structure support trusses have relatively small torsional resistance, especially in steel roof trusses, which is more significant. During the construction and use of these trusses, due to external force factors, the trusses are deformed, greatly reducing the safety of the trusses, and causing potential safety hazards in the buildings constructed with them.

During the construction and use of these trusses, due to external force factors, the trusses are deformed, greatly reducing the safety of the trusses, and causing potential safety hazards in the buildings constructed with them. The utility model proposes a high-safety torsion-resistant steel structure support truss.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a high-safety torsion-resistant steel structure support truss, including a truss body. The truss body includes a cross beam, and both ends of the cross beam are fixedly connected with vertical frames. The surface of the cross beam is movably connected with a torsion-resistant mechanism;

One side of the support rod is fixedly connected with a limit stud. The surface of the limit stud is threadedly connected with a rotating block. One side of the rotating block is movably connected with a mounting block. One side of the mounting block is fixedly connected with one side of the cross beam.

[0007] Preferably, a fixing hole is opened inside the cross beam. The number of fixing holes is multiple. A positioning hole is opened inside the concave block. Positioning bolts are movably connected inside the fixing hole and the positioning hole.

[0008] Preferably, an installation groove is opened on one side of the concave block. The upper and lower ends of the fixed column are fixedly connected with the inside of the installation groove.

[0009] Preferably, springs are sleeved on both the top and bottom of the surface of the fixed column. One end of each spring is fixedly connected to one end of the installation groove, and the other end of each spring is fixedly connected to one end of the rotating column.

[0010] Preferably, a concave groove is formed on one side of the concave block. The shape of the concave groove is concave, and the inner wall of the concave groove is movably connected to the surface of the cross beam.

[0011] Preferably, a clamping groove is formed inside the installation block. The height of the clamping groove is the same as the diameter of the limit stud, and the inside of the clamping groove is movably connected to the surface of the limit stud.

[0012] Preferably, a clamping nut is threadedly connected to the rear end of the surface of the positioning bolt, and the front side of the clamping nut is movably connected to the back side of the cross beam.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The following will further elaborate on this application Figures 1-4 in further detail.

[0023] The embodiments of this application disclose a high-safety anti-torsion steel structure support truss. Refer to Figure 1 and Figure 4 , a high-safety anti-torsion steel structure support truss includes a truss body 1. The truss body 1 includes a cross beam 101. Vertical frames 102 are fixedly connected to both ends of the cross beam 101. An anti-torsion mechanism 2 is movably connected to the surface of the cross beam 101;

[0024] The anti-torsion mechanism 2 includes concave blocks 204. The number of concave blocks 204 is four. A fixed column 210 is movably connected to one side of the concave block 204. A rotating column 203 is movably connected to the surface of the fixed column 210. A support rod 202 is fixedly connected to the surface of the rotating column 203. A limit stud 208 is fixedly connected to one side of the support rod 202. A rotating block 207 is threadedly connected to the surface of the limit stud 208. A mounting block 201 is movably connected to one side of the rotating block 207. One side of the mounting block 201 is fixedly connected to one side of the cross beam 101.

[0025] Refer to Figure 2 and Figure 4, fixing holes 206 are formed inside the cross beam 101, and the number of the fixing holes 206 is multiple. Positioning holes 212 are formed inside the concave block 204. Positioning bolts 205 are movably connected inside both the fixing holes 206 and the positioning holes 212. Through the arrangement of the fixing holes 206 and the positioning holes 212, the positioning bolts 205 can be inserted into the inside of the concave block 204 and the cross beam 101, thereby connecting the concave block 204 and the cross beam 101 and fixing their positions;

[0026] Referring to Figure 4 , an installation groove 211 is formed on one side of the concave block 204. The upper and lower ends of the fixing column 210 are fixedly connected to the inside of the installation groove 211. Through the arrangement of the installation groove 211, the position of the fixing column 210 can be fixed, so that the rotating column 203 will not break away from the concave block 204 when rotating on the surface of the fixing column 210;

[0027] Referring to Figure 4 , springs 209 are sleeved on the top and bottom of the surface of the fixing column 210. One end of the spring 209 is fixedly connected to one end of the installation groove 211, and the other end of the spring 209 is fixedly connected to one end of the rotating column 203. Through the arrangement of the spring 209, when receiving an outward pulling force, the spring 209 undergoes elastic deformation, driving the limit stud 208 to disengage from the clamping of the clamping groove 215. When not affected by external forces, the elastic action of the spring 209 can drive the limit stud 208 to always be inside the clamping groove 215;

[0028] Referring to Figure 1 and Figure 4 , a concave groove 214 is formed on one side of the concave block 204. The shape of the concave groove 214 is concave, and the inner wall of the concave groove 214 is movably connected to the surface of the cross beam 101. Through the arrangement of the concave groove 214, the concave block 204 can be tightly attached to the surface of the cross beam 101, further enhancing the torsional resistance of the cross beam 101;

[0029] Referring to Figure 4 , a clamping groove 215 is formed inside the installation block 201. The height of the clamping groove 215 is the same as the diameter of the limit stud 208, and the inside of the clamping groove 215 is movably connected to the surface of the limit stud 208. Through the arrangement of the clamping groove 215, the position of the limit stud 208 is limited, so that the limit stud 208 can be clamped into the inside of the installation block 201;

[0030] Referring to Figure 2, a clamping nut 213 is threadedly connected to the rear end of the surface of the positioning bolt 205. The front side of the clamping nut 213 is movably connected to the back side of the cross beam 101. Through the setting of the clamping nut 213, when the positioning bolt 205 is inserted into the positioning hole 212 and the fixing hole 206, the threaded connection of the positioning bolt 205 is tightened by the clamping nut 213, so that the two concave blocks 204 can firmly fit against the cross beam 101.

[0031] Working principle: When the front and rear concave blocks 204 are fitted against the cross beam 101, the positioning bolt 205 is inserted into the positioning hole 212 and the fixing hole 206, and then the threaded connection of the positioning bolt 205 is carried out through the clamping nut 213, so that the two concave blocks 204 can move inward until the cross beam 101 is clamped. Then, the rotating column 203 will rotate on the surface of the fixed column 210 through the elastic action of the spring 209. The support rod 202 is driven to move by the rotating column 203, and the limiting stud 208 is driven to move into the clamping groove 215 through the support rod 202. Then, through the threaded connection of the rotating block 207 to the limiting stud 208, the rotating block 207 rotates to one side of the mounting block 201, thereby fixing the limiting stud 208.

[0032] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
