Description

Technical Field

[0001] This invention relates to the field of steel structure support truss technology, specifically a steel structure support truss with anti-torsional function. Background Technology

[0002] Steel structure support trusses are trusses made of steel and have a wide range of applications. For example, steel trusses are commonly used as the main load-bearing components in the roofs (roof trusses, etc.) and crane beams (i.e., crane trusses) of industrial and civil buildings, bridges, cranes (their towers, beams or booms, etc.), hydraulic gates, and offshore oil platforms. Various types of steel space frames, which are frequently used in the roof structures of large-span public buildings, belong to space steel trusses. Various types of towers, such as towers for television, power transmission, drilling, and cranes, and mast towers, are often space steel trusses composed of three-sided, four-sided, or multi-sided planar trusses.

[0003] In single-story factory steel frames, roof steel trusses often form single-span or multi-span rigid frames with steel columns. They have high horizontal stiffness and can better adapt to the requirements of large cranes or vibration loads. In existing roof steel truss structures, steel trusses and steel columns are usually assembled by bolting or welding. Regardless of whether bolting or welding is used, the length of the steel truss needs to be standardized and then positioned and drilled to ensure a stable connection between the steel truss and the steel column. Furthermore, the vertical positioning connection between the two gives the steel structure torsion resistance.

[0004] However, as mentioned above, this type of steel truss requires that the mounting holes of the steel columns and steel trusses must correspond when bolting. Furthermore, the length of the steel truss is not adjustable and must be cut to size. During actual on-site installation, the offset position of the bottom cement base causes the steel column installation position to shift, resulting in frequent misalignment of the connection holes between the steel columns and steel trusses. This leads to on-site construction workers spending a significant amount of time adjusting, hindering the ability to achieve rapid installation. Additionally, when the existing steel truss span is large, it requires splicing two or more steel trusses for extension. Current splicing methods mostly involve clamping two plates at both ends of the inner side of the steel truss and connecting them with bolts. Sometimes, to ensure structural stability at the connection point, an inverted triangular bracket is installed at the bottom to reinforce the connection. However, this type of splicing structure requires that the bottom of the steel truss be avoided when installing other mechanical components, thus affecting the subsequent assembly of mechanical parts. Summary of the Invention

[0005] The purpose of this invention is to provide a steel structure support truss with anti-torsion function to solve the problems mentioned in the background art, such as the inconvenience of quick installation of existing steel structure support trusses and the lack of optimization of the connection structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: It includes two sets of mounting bases, each set of mounting bases having an I-beam support column at its top. I-beam beams A and B are spliced ​​together on the sides of the tops of the two sets of I-beam support columns that are close to each other. A positioning and adjustment connecting component is provided between the ends of I-beam beams A and B near the I-beam support columns and the I-beam support columns. The positioning and adjustment connecting component is used to position and adjust the I-beam beams A and B to the I-beam support columns. A support connecting component is provided at the ends of I-beam beams A and B that are close to each other, and the support connecting component is used to bolt I-beam beams A and B together.

[0007] Preferably, the positioning and adjusting connecting component includes two sets of fixed clamping plates welded to the inner side of the top of the I-beam support column. One end of the I-beam beam A is inserted between the two sets of fixed clamping plates. Six sets of adjusting connecting through holes are provided through both ends of the fixed clamping plates. Four sets of movable clamping plates are symmetrically arranged at the ends of the two sets of fixed clamping plates that are far apart from each other. The ends of the two sets of movable clamping plates that are far apart from each other are provided with mounting bolts A that pass through the movable clamping plates, fixed clamping plates, adjusting connecting through holes, and I-beam beam A. An adjusting bolt that passes through the I-beam support column is provided on the side of the movable clamping plate near the I-beam support column. A locking nut B that fits against the I-beam support column is provided on the outside of the adjusting bolt. By adjusting the locking nut B on the outside of the adjusting bolt, the distance between the movable clamping plate and the I-beam support column is adjusted, thereby realizing the function of moving the I-beam beam A or I-beam beam B on the outside of the mounting bolt A.

[0008] Preferably, the adjusting connection through hole is an oblong hole structure, and the two ends of the I-beam A and the movable clamp are provided with circular holes corresponding to the adjusting connection through hole. By adjusting the oblong hole structure of the connecting through hole, the mounting bolt A can drive the I-beam A or I-beam B to perform lateral displacement adjustment.

[0009] Preferably, an L-shaped support plate, bolted to the I-beam support column, is provided on the inner side of the top of the I-beam support column near the bottom of the I-beam beam A. The two ends of the L-shaped support plate away from the I-beam support column are symmetrically provided with mounting bolts B that penetrate the I-beam support column and the L-shaped support plate. A support top plate, tightly fitted to the bottom of the I-beam beam A, is provided on the top of the L-shaped support plate. Four sets of positioning grooves are evenly provided on the bottom of the support top plate. Four sets of internally threaded through holes are symmetrically provided on both ends of the bottom of the L-shaped support plate. A support adjusting bolt, adapted to the internally threaded through holes and extending into the positioning grooves, is provided on the bottom of the L-shaped support plate. An adjusting nut, tightly fitted to the bottom of the L-shaped support plate, is provided on the outside of the support adjusting bolt. By providing an adjustable support adjusting bolt, the horizontal position of the support top plate on either the I-beam beam A or the I-beam beam B can be adjusted.

[0010] Preferably, splicing clamps are provided on both sides of the I-beam A and I-beam B at their respective ends. Two sets of support plates are symmetrically arranged at the middle of the two sets of splicing clamps at their respective ends. A bidirectional threaded rod is provided through the two sets of support plates on their respective ends. A hexagonal nut is provided at the middle of the outer side of the bidirectional threaded rod. A hinged support column is hinged to the top and bottom of the support plate. An extrusion plate that fits tightly against the inner wall of I-beam A and I-beam B is hinged to the end of the hinged support column away from the support plate. Internal threaded sleeves are symmetrically arranged at both ends of the outer side of the bidirectional threaded rod. Adjustable support columns that are hinged to the hinged support columns are provided at the top and bottom of the internal threaded sleeves. The hinged support columns provide support for the extrusion plate, and the position and height of the hinged support columns can be adjusted by the adjustable support columns.

[0011] Preferably, locking nuts A are symmetrically arranged at both ends of the outer side of the bidirectional threaded rod, which fit against the side of the support plate. A smooth through hole adapted to the bidirectional threaded rod is provided in the middle of the support plate. Eight sets of mounting bolts C are provided at the ends of the two sets of splicing clamps that are far apart from each other. The mounting bolts C pass through the middle of the I-beam A and I-beam B respectively. The top and bottom of the splicing clamps fit against the top and bottom of the inner side of the I-beam A and I-beam B respectively. The bolt connection between the two sets of splicing clamps is realized by providing eight sets of mounting bolts C.

[0012] Compared with the prior art, the present invention provides a steel structure support truss with anti-torsional function, which has the following beneficial effects:

[0013] 1. This invention provides adjustable connecting through holes at both ends of two sets of fixed clamping plates. An I-beam A is inserted through the middle of the two sets of fixed clamping plates, thereby clamping a movable clamping plate on the outside of the two sets of fixed clamping plates. An installation bolt A passes through the movable clamping plate, the fixed clamping plates, and the I-beam A. By adjusting the nut on one side of the adjusting bolt, the adjusting bolt and the movable clamping plate are connected to the I-beam support column. Adjusting the displacement space of the connecting through holes allows the movable clamping plate to adjust the position of the I-beam A located on the outside of the installation bolt A. This optimizes the existing structure's problem of fixed-size cutting of the I-beam support column and I-beam A, which makes installation difficult, thus improving installation efficiency. Furthermore, this structure achieves a vertical connection between the I-beam support column and I-beam A, providing them with anti-torsional properties.

[0014] 2. This invention utilizes an L-shaped support plate bolted to an I-beam support column, allowing the top support plate of the L-shaped support plate to support the bottom of the I-beam A. When the horizontal position of the I-beam A needs adjustment, the bolted connection between the adjusting support bolt and the L-shaped support plate is rotated, causing the adjusting support bolt to move up and down. This adjustment bolt then supports the bottom of the top support plate, thereby adjusting the horizontal position of the I-beam A at the top of the top support plate. Tightening the adjusting nut secures the adjusting support bolt and the L-shaped support plate. This invention optimizes the existing steel truss structure where the height cannot be adjusted, improves the adaptability of the device, and further ensures the stable support of the device structure.

[0015] 3. This invention connects the I-beams A and B at their joint using two sets of splicing clamps, and bolts C are used for bolting. Furthermore, adjusting the hexagonal nut rotates the bidirectional threaded rod, causing the internal threaded blocks at both ends to drive the adjusting support column, which in turn supports the hinged support column. The hinged support column then drives the pressing plate to support the inner ends of the I-beams A and B. By transmitting force to the splicing clamps, the supporting force of the splicing clamps on the inner sides of the I-beams A and B is increased, resulting in a more stable structural connection at the joint. This optimizes the existing structure that uses inverted triangular supports at the bottom of the I-beams A and B, without occupying the bottom space of either beam, thus ensuring the rationality of the device's structural design.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1:

[0025] Please see Figure 1-6 The present invention provides a technical solution: a steel structure support truss with anti-torsion function, including two sets of mounting bases 1, each set of mounting bases 1 is provided with an I-beam support column 2 at the top, and I-beam beams A4 and B6 are spliced ​​on the side of the top of the two sets of I-beam support columns 2 that are close to each other. The end of I-beam beams A4 and B6 that is close to the I-beam support column 2 is provided with a positioning adjustment connecting component 3. The positioning adjustment connecting component 3 is used to position and adjust the I-beam beams A4 and B6 to the I-beam support column 2.

[0026] As a preferred embodiment, the positioning and adjusting connecting component 3 includes two sets of fixed clamping plates 10 welded to the inner side of the top of the I-beam support column 2. One end of the I-beam beam A4 is inserted between the two sets of fixed clamping plates 10. Six sets of adjusting connecting through holes 11 are provided through both ends of the fixed clamping plates 10. Four sets of movable clamping plates 8 are symmetrically arranged at the ends of the two sets of fixed clamping plates 10 that are far apart from each other. The ends of the two sets of movable clamping plates 8 that are far apart from each other are provided with mounting bolts A9 that pass through the movable clamping plates 8, the fixed clamping plates 10, the adjusting connecting through holes 11 and the I-beam beam A4. An adjusting bolt 12 that passes through the I-beam support column 2 is provided on the side of the movable clamping plate 8 near the I-beam support column 2. A locking nut B that fits against the I-beam support column 2 is provided on the outside of the adjusting bolt 12. By adjusting the locking nut B on the outside of the adjusting bolt 12, the distance between the movable clamping plate 8 and the I-beam support column 2 is adjusted, thereby realizing the function of moving the I-beam beam A4 or I-beam beam B6 on the outside of the mounting bolt A9.

[0027] As a preferred embodiment, the adjusting connection through hole 11 is an elongated oval hole structure. The two ends of the I-beam A4 and the movable clamping plate 8 are provided with round holes corresponding to the adjusting connection through hole 11. By adjusting the elongated oval hole structure design of the adjusting connection through hole 11, the mounting bolt A9 can drive the I-beam A4 or the I-beam B6 to perform lateral displacement adjustment.

[0028] As a preferred embodiment: An L-shaped support plate 13, bolted to the I-beam support column 2, is provided on the inner side of the top of the I-beam support column 2, near the bottom of the I-beam beam A4. Mounting bolts B15, penetrating the I-beam support column 2 and the L-shaped support plate 13, are symmetrically arranged at both ends of the L-shaped support plate 13 on the side away from the I-beam support column 2. A support top plate 7, tightly fitted to the bottom of the I-beam beam A4, is provided on the top of the L-shaped support plate 13. Four sets of positioning grooves 17 are evenly arranged on the bottom of the support top plate 7. Four sets of internally threaded through holes 18 are symmetrically arranged at both ends of the bottom of the L-shaped support plate 13. A support adjustment bolt 14, adapted to the internally threaded through holes 18 and extending into the positioning grooves 17, is provided on the bottom of the L-shaped support plate 13. An adjustment nut 16, tightly fitted to the bottom of the L-shaped support plate 13, is provided on the outer side of the support adjustment bolt 14. By providing the support adjustment bolt 14 with adjustable position length, the horizontal position of the I-beam beam A4 or I-beam beam B6 can be adjusted by the support top plate 7.

[0029] like Figure 1 , 2As shown in Figures 3 and 4, when it is necessary to connect the I-beam support column 2 with the I-beam crossbeams A4 and B6, the I-beam crossbeam A4 or B6 is lifted by a crane, so that one end of the I-beam crossbeam A4 or B6 is close to the bottom of the I-beam support column 2 and inserted into the inner side of the two sets of fixed clamping plates 10. At this time, the movable clamping plate 8 is attached to the outer side of the fixed clamping plate 10, and the mounting bolt A9 passes through the two sets of movable clamping plates 8 and the fixed clamping plate 10, and at the same time passes through one end of the I-beam crossbeam A4 or B6. At this time, the two ends of the mounting bolt A9 form a positioning through-structure with the two sets of movable clamping plates 8, and the middle part of the outer side of the mounting bolt A9 also forms a positioning through-structure with the I-beam crossbeam A4 or B6. Since the adjustment connection through holes 11 set at both ends of the fixed clamping plate 10 have lateral displacement space, the connection is complete. This allows the mounting bolt A9 to drive the movable clamping plate 8 and the I-beam A4 to adjust their lateral displacement. By adjusting the nut on the outside of the adjusting bolt 12 on one side of the movable clamping plate 8, the distance between the movable clamping plate 8 and the I-beam support column 2 is adjusted. In turn, the movable clamping plate 8 drives the I-beam A4 or I-beam B6 on the outside of the mounting bolt A9 to adjust their lateral displacement. When the predetermined position is reached, the nut on the outside of the adjusting bolt 12 is tightened, and the mounting bolt A9 is tightened, so that the movable clamping plate 8 and the fixed clamping plate 10 fix and clamp the I-beam A4 or I-beam B6. This optimizes the requirement of fixed-size cutting and positioning drilling in the existing assembly structure, making the device more adaptable to the actual installation requirements on site, improving the assembly efficiency of the steel truss structure, and ensuring the stability of the device.

[0030] Meanwhile, the L-shaped support plate 13 is bolted to the I-beam support column 2. When it is necessary to adjust the horizontal position of the I-beam beam A4, the support adjustment bolt 14 is rotated to make it threadedly connected to the L-shaped support plate 13. Then, the length of the top of the L-shaped support plate 13 at the extension of the support adjustment bolt 14 is adjusted. By adjusting the length of the top of the support adjustment bolt 14, the support top plate 7 is supported, thereby adjusting the horizontal position of the I-beam beam A4 at the top of the support top plate 7. This optimizes the actual installation problem of the fixed connection that cannot be adjusted in the existing structure and improves the adaptability of the device.

[0031] Example 2:

[0032] The difference from Embodiment 1 is that: the I-beam A4 and I-beam B6 are provided with a supporting connecting member 5 at their close ends, and the supporting connecting member 5 is used to bolt the I-beam A4 and I-beam B6 together.

[0033] As a preferred embodiment: Splicing plates 21 are provided on both sides of the I-beams A4 and B6 at their closest points. Two sets of support plates 22 are symmetrically arranged at the middle of the two sets of splicing plates 21 at their furthest points. A bidirectional threaded rod 24 is threaded through the two sets of support plates 22 on their furthest sides. A hexagonal nut 23 is provided at the middle of the outer side of the bidirectional threaded rod 24. Hinged support columns 20 are hinged to the top and bottom of the support plates 22, respectively. The hinged support columns 20 are furthest from the support plates. One end of plate 22 is hinged to an extrusion plate 19 that fits tightly against the inner wall of I-beam A4 and I-beam B6. Two ends of the outer side of the bidirectional threaded rod 24 are symmetrically provided with internal threaded sleeves 27. The top and bottom of the internal threaded sleeves 27 are respectively provided with adjusting support columns 25 that are hinged to the hinged support columns 20. The hinged support columns 20 provide support for the extrusion of the extrusion plate 19, and the position and height of the hinged support columns 20 can be adjusted by the adjusting support columns 25.

[0034] As a preferred embodiment: The two ends of the bidirectional threaded rod 24 are symmetrically provided with locking nuts A26 that fit against the side of the support plate 22. The middle of the support plate 22 is provided with a smooth through hole that matches the bidirectional threaded rod 24. The two sets of splicing clamps 21 are provided with eight sets of mounting bolts C28 at their far ends. The mounting bolts C28 pass through the middle of the I-beam A4 and I-beam B6 respectively. The top and bottom of the splicing clamps 21 fit against the top and bottom of the inner side of the I-beam A4 and I-beam B6 respectively. By providing eight sets of mounting bolts C28, the bolt connection between the two sets of splicing clamps 21 is realized.

[0035] like Figure 1 , 5 As shown in Figure 6, two sets of splicing clamps 21 are provided on the inner sides of I-beam A4 and I-beam B6, and the splicing positions of I-beam A4 and I-beam B6 are clamped by the two sets of splicing clamps 21. This, combined with the through-positioning of eight sets of mounting bolts C28, allows the I-beam A4, I-beam B6, and splicing clamps 21 to be bolted together. At this time, rotating the hexagonal nut 23 drives the bidirectional threaded rod 24 to rotate, causing the internal threaded sleeve 27 to move outside the bidirectional threaded rod 24. The internal threaded sleeve 27... The displacement causes the adjusting support column 25 to support the hinged support column 20, which in turn causes the pressing plate 19 to press and support the two ends of the inner side of the I-beam A4 and I-beam B6. Then, the locking nut A26 is tightened to position the bidirectional threaded rod 24, thereby improving the stability of the splicing plate 21 at the splicing position of the I-beam A4 and I-beam B6. This optimizes the existing structure with inverted triangular support frame, avoids the occupation of space at both ends of the I-beam A4 or I-beam B6, and improves the rationality of the steel truss assembly.

[0036] Working principle: The horizontal position of the I-beam A4 or I-beam B6 is adjusted by the adjustable support plate 7. The connection between the I-beam support column 2 and the I-beam A4 or I-beam B6 is achieved by the positioning and adjustment connecting component. This optimizes the existing non-adjustable connection method and improves assembly efficiency. At the same time, the support connecting component ensures a stable connection at the splice of the I-beam A4 and I-beam B6, improving the stability of the structure.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
