Description

Technical Field

[0001] This utility model relates to the field of support truss technology, specifically a high-strength steel structure support truss. Background Technology

[0002] A truss is a structure consisting of members connected to each other at both ends by hinges. Trusses are planar or spatial structures composed of straight members and generally have triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight and increase stiffness compared to solid beams.

[0003] For example, the patent application CN216276457U discloses a high-strength steel structure support truss, including a first truss, a second truss at the right end of the first truss, a triangular plate at the corner of the first and second trusses, and two first screws fixedly installed on the right end of the triangular plate, located on the front and rear sides of the second truss respectively. The two first screws are externally connected to a first rectangular plate located on the right side of the second truss, and the external threads of the first screws are connected to a first nut located on the right side of the first rectangular plate. This patent states that it possesses the advantage of high strength performance, solving the problem that existing steel structure support trusses tend to twist and deform during long-term use, leading to truss collapse, which adversely affects users and causes economic losses.

[0004] However, the high-strength steel structure support truss mentioned in the patent does not optimize the stability of the frame connection. Therefore, when the whole is subjected to lateral force, the stability of the connection between the frame and the column cannot be guaranteed, which will lead to the connection falling off. At the same time, when subjected to the pressure of the object above for a long time, the pressure of the diagonal brace is large, which will cause damage to the connection and thus fail to guarantee the overall stability. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength steel structure support truss to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-strength steel structure support truss includes a truss top chord, a vertical bar fixedly installed at the bottom end of the top chord, a truss bottom chord fixedly installed on the side of the vertical bar away from the top chord, a connecting mechanism provided at both ends of the top and bottom chords, a diagonal brace fixedly installed between the vertical bars, and a triangular top bar fixedly installed on the diagonal brace, with the triangular top bar fixedly installed on one side of the top and bottom chords respectively.

[0008] Preferably, the connecting mechanism includes a column, an assembly plate is fixedly installed at the bottom of the column, a diagonal brace is fixedly installed between the assembly plate and the column, and an assembly hole is provided on the assembly plate near the diagonal brace.

[0009] Preferably, the upper chord and lower chord of the truss are fixedly installed on the side of the column away from the assembly plate, and a triangular block is fixedly installed on the side of the column away from the assembly plate.

[0010] Preferably, a fixing screw is fixedly installed on the triangular block, and the triangular block is fixedly installed at the upper and lower ends of the upper chord and lower chord of the truss.

[0011] Preferably, a type 7 plate is fixedly installed on the side of the column away from the triangular block, and a connecting screw is fixedly installed between the type 7 plate and the column.

[0012] Preferably, the upper chord and lower chord of the truss are fixedly installed on the side of the 7-type plate away from the connecting screw, and a locking screw is fixedly installed between the 7-type plate and the upper chord and lower chord of the truss.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-strength steel structure support truss improves the stability of the triangular area formed at the connection between the diagonal brace and the vertical bar by using a triangular top bar, which alleviates the diagonal bracing pressure of the diagonal brace and thus ensures the vertical strength of the overall support truss.

[0015] 2. This high-strength steel structure support truss can improve the stability of the connection between the upper and lower chords of the truss and the column by using 7-type plates and triangular blocks. Multiple connections and the generation of triangular support forces can improve the strength of the connection, thereby preventing the connection from falling off when lateral forces are generated.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A high-strength steel structure support truss includes an upper chord 101, a vertical bar 102 fixedly installed at the bottom of the upper chord 101, a lower chord 103 fixedly installed on the side of the vertical bar 102 away from the upper chord 101, a connecting mechanism 104 provided at both ends of the upper chord 101 and the lower chord 103, a diagonal brace 105 fixedly installed between the vertical bars 102, and a triangular top bar 106 fixedly installed on the diagonal brace 105. The triangular top bar 106 is fixedly installed on one side of the upper chord 101 and the lower chord 103 respectively.

[0024] The above scheme provides support for the upper structure through the truss upper chord, buffers the pressure on the truss upper chord with the truss lower chord through the vertical rods, generates diagonal tension through the diagonal bracing to reduce the pressure on the truss upper and lower chords, thus keeping the frame stable, and improves the stability of the triangular area formed at the connection between the diagonal bracing and the vertical rod through the triangular top rod, relieving the diagonal bracing pressure, thereby ensuring the vertical strength of the overall supporting truss.

[0025] In this embodiment, preferably, the connecting mechanism 104 includes a column 201, an assembly plate 202 is fixedly installed at the bottom of the column 201, a diagonal brace 203 is fixedly installed between the assembly plate 202 and the column 201, and an assembly hole 204 is formed on the assembly plate 202 near the diagonal brace 203.

[0026] The above solution allows the frame to be supported by the uprights, and the assembly plates to be fixed by the assembly holes, thus securing the uprights. The diagonal bracing plates can improve the stability of the upright installation.

[0027] In this embodiment, preferably, the upper chord 101 and the lower chord 103 of the truss are fixedly installed on the side of the column 201 away from the assembly plate 202, and a triangular block 205 is fixedly installed on the side of the column 201 away from the assembly plate 202.

[0028] The above solution uses triangular blocks to improve the stability of the connection between the upper and lower chords of the truss, ensuring that the connection will not detach when the entire structure is subjected to lateral forces.

[0029] In this embodiment, preferably, a fixing screw 206 is fixedly installed on the triangular block 205, and the triangular block 205 is fixedly installed at the upper and lower ends of the upper chord 101 and the lower chord 103 of the truss.

[0030] The above method allows the triangular block to be installed and fixed by using a fixing screw.

[0031] In this embodiment, preferably, a 7-type plate 301 is fixedly installed on the side of the column 201 away from the triangular block 205, and a connecting screw 302 is fixedly installed between the 7-type plate 301 and the column 201.

[0032] The above scheme can increase the stability of the connection between the upper chord and lower chord of the truss and the columns by using the type 7 plate, and the columns can be fixed together by using connecting bolts.

[0033] In this embodiment, preferably, the upper chord 101 and the lower chord 103 of the truss are fixedly installed on the side of the 7-type plate 301 away from the connecting screw 302, and a locking screw 303 is fixedly installed between the 7-type plate 301 and the upper chord 101 and the lower chord 103 of the truss.

[0034] The above method allows the upper chord of the truss and the upper chord of the truss to be fixed to the type 7 plate by using locking screws.

[0035] In this embodiment, a high-strength steel structure support truss is used such that the user fixes the assembly plate 202 through the assembly hole 204 to provide vertical support for the column 201. Then, the vertical rod 102 is welded between the upper chord 101 and the lower chord 103 of the truss, and the diagonal brace 105 is welded to the connection points of the vertical rod 102 with the upper chord 101 and the lower chord 103. Simultaneously, the triangular top rod 106 is welded to the upper chord 101 and the lower chord 103 of the truss. After welding, the assembled upper chord 101 and lower chord 103 of the truss are lifted between the columns 201 and welded. Finally, triangular blocks 205 are installed at the connection points of the upper chord 101 and the columns 201, and at the connection points of the lower chord 103 and the columns 201. After connection, the triangular block 205 is fixed by the fixing screw 206. Then, the 7-type plate 301 is installed on the side away from the triangular block 205, and the 7-type plate 301 is fixed to the column 201 by the connecting screw 302 and fixed to the upper chord 101 and lower chord 103 of the truss by the locking screw 303. After fixing, the assembly of the overall support truss is completed. When supporting, the triangular block 205 can improve the stability of the connection between the upper chord 101 and lower chord 103 of the truss and the column 201, so that the connection can be prevented from falling off when lateral force is generated. The triangular top rod 106 improves the stability of the triangular area formed at the connection between the diagonal brace 105 and the vertical rod 102, relieves the diagonal bracing pressure of the diagonal brace 105, and thus ensures the vertical strength of the overall support truss.
