Description

Technical Field

[0001] The utility model relates to the technical field of truss beams, and more specifically, to a connecting structure for the chords and web members of a corridor truss. Background Technique

[0002] A truss beam is a structure widely used in bridges and buildings. It consists of many web members. The truss beam is introduced as a large-scale support structure due to its excellent bending resistance and strong deformation coordination ability.

[0003] The existing technical patent (CN213115028U) discloses a truss beam assembling device, which includes a first steel plate and a second steel plate. The two ends of the first steel plate are bent reversely to form two parallel first ends and second ends. The two ends of the second steel plate are bent in the same direction to form two parallel first braces and second braces. The first ends and the second ends are perpendicular to the steel plate body of the first steel plate. An obtuse angle is formed between the first braces and the second braces and the steel plate body of the second steel plate. In the actual use of the above patent, when fixing the web members in the truss beam, most of them use screws and reinforcing ribs for fixation. The fixing points are single. After long-term use, the screws are prone to loosen, resulting in looseness at the connection between the web members connected in pairs and the chords of the corridor truss, making the connection between the two unreliable, thus affecting the stability of the entire truss beam. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a connecting structure for the chords and web members of a corridor truss, aiming at the deficiencies of the existing technology, and it can solve the problems raised in the above background technique.

A fixing member connected to the first mounting hole is installed on the connecting frame. Both vertical sections of the hanger are connected to the connecting frame. A shock-absorbing structure detachably connected to the connecting frame is installed on the side wall of the hanger.

[0007] In some technical solutions of the utility model, the hanger is in a "C" shape. A plurality of first screws threadedly connected to it are installed on the horizontal section of the hanger. A first internal threaded hole for threaded connection with the first screw is opened at the top of the chords of the corridor truss.

[0008] In some technical solutions of the utility model, the fixing member is two second screws arranged in pairs. The second screws extend outwards after passing through the first mounting holes. A second nut threadedly connected to it is installed on the extending end of the second screw.

[0009] In some technical solutions of this utility model, the shock-absorbing structure includes two hydraulic rods arranged in pairs and a clamp. The bodies of the two hydraulic rods are respectively installed on two vertical sections of the hanger, and the clamp is installed at the bottom of the connecting frame. The telescopic ends of the hydraulic rods are all connected to the clamp.

[0023] Example

[0024] This utility model provides a connection structure for the chord 1 and web member 6 of a connecting corridor truss, such as... Figures 1-5As shown, the system includes a hanger 2 installed on the chord 1 of the connecting corridor truss. The hanger 2 is "U"-shaped and integrally formed from a single piece of steel. Several first screws 3 are threadedly connected to the horizontal section of the hanger 2. The top of the chord 1 of the connecting corridor truss has a first internal threaded hole for threaded connection with the first screws 3. The hanger 2 is screwed into the first internal threaded hole at the top of the chord through the first screws 3, forming a rigid fixed connection. Several first mounting holes 10 are provided on the side wall of the chord 1 along its extension direction, and the first mounting holes 10 are equidistantly arranged along the extension direction of the chord 1. An integrally formed connecting frame 4 is installed at the end of the web member 6. The connecting frame 4 is equipped with a fastener that connects to the first mounting hole 10. The connecting frame 4 and the fastener, in conjunction with the first mounting hole 10, allow for flexible connection between the web member 6 and the chord, and change the connection angle between the chord 1 and the web member 6, facilitating position adjustment and adapting to different span requirements. Both vertical sections of the hanger 2 are connected to the connecting frame 4 to enhance the bending and shear resistance of the connecting frame 4 when it is connected to the chord of the connecting corridor truss 1, preventing deformation under stress. A damping structure, detachably connected to the connecting frame 4, is installed on the side wall of the hanger 2. This damping structure dynamically absorbs vibration energy, enabling multi-directional damping adjustment and reducing fatigue damage to various components after the connecting corridor truss chord 1 and web members 6 are connected.

[0025] In some technical solutions of this utility model, the fixing component consists of two paired second screws 5. The second screws 5 extend outward after passing through the first mounting hole 10, and a second nut is installed on the extended end of the second screw 5 for threaded connection. The connecting bracket 4 located at the end of the web member 6 passes through the first mounting hole 10 of the chord member through the second screw 5 and is locked by the second nut, realizing a lateral connection and strengthening the connection strength between the chord member 1 and the web member 6 of the connecting corridor truss.

[0026] In some technical solutions of this utility model, the shock-absorbing structure includes two hydraulic rods 8 arranged in pairs and a clamp 7. The bodies of the two hydraulic rods 8 are respectively installed on two vertical sections of the hanger 2 via lugs and shafts. The clamp 7 is installed at the bottom of the connecting frame 4, and the telescopic ends of the hydraulic rods 8 are connected to the clamp 7. The clamp 7 has a groove inside that is adapted to the connecting frame 4.

[0027] Preferably, the clamp 7 is connected to the connecting frame 4 via the fourth screw 9.

[0028] Tie rods 14 are welded to both vertical sections of the clamp 7. A first adjusting sleeve 13, threadedly connected to the side wall of the tie rod 14, is installed on the side wall of the tie rod 14. An extension rod 11, connected to the extension rod 8 via a connecting sleeve or welding, is installed on the telescopic end of the extension rod 11. A second adjusting sleeve 12, threadedly connected to the extension rod 11, is installed on the outer side wall of the extension rod 11. A connecting rod 15 is detachably provided between the first adjusting sleeve 13 and the second adjusting sleeve 12. The connecting rod 15 is connected to the first adjusting sleeve 13 or the second adjusting sleeve 12 via a pin connection.

[0029] In some technical solutions of this utility model, a sliding groove 16 is provided on the vertical section of the hanger 2, and a slider 17 adapted to the sliding groove 16 is installed on the vertical section of the clamp 7. The slider 17 is slidably disposed in the sliding groove 16. After the sliding groove 16 and the slider 17 are engaged, the clamp 7 is allowed to slide along the vertical section of the hanger 2, which facilitates alignment during installation and improves installation efficiency and accuracy.

[0030] When external loads (such as wind vibration or earthquakes) are applied, the telescopic end of the hydraulic rod 8 transmits the vibration to the body of the hydraulic rod 8 through the clamp 7. The hydraulic rod 8 is used to achieve hydraulic damping energy dissipation, dynamically absorb vibration energy, realize multi-directional vibration reduction adjustment, and reduce fatigue damage. Changing the relative positions of the first adjusting sleeve 13 and the pull rod 14, and the second adjusting sleeve 12 and the connecting rod 15, can adjust the initial preload of the vibration reduction structure to adapt to different amplitudes; and in conjunction with the slide groove 16 and the slider 17, the clamp 7 can be slightly displaced relative to the hanger 2 to avoid stress concentration.

[0031] In some technical solutions of this utility model, a locking block 18 is installed on the inner side wall of the clamp 7, and a locking groove adapted to it is provided on the side wall of the connecting frame 4. The locking block 18 provided on the inner side of the clamp 7 and the locking groove provided on the connecting frame 4 can enhance the stability of the two after assembly and prevent the clamp 7 from shifting during use.

[0032] In some technical solutions of this utility model, the vertical section of the hanger 2 and the side wall of the connecting frame 4 are provided with several third internal threaded holes, and a third screw 19 is provided in the third internal threaded hole for threaded connection. The third screw 19 and the third internal threaded hole provide additional fixing points for the connection of the chord 1 and web member 6 of the connecting corridor truss, and prevent the risk of slippage of the hanger 2, ensuring the stability of the connecting corridor truss chord 1 and web member 6 after connection, while facilitating disassembly and maintenance.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
