[0033] like Figure 1-Figure 4As shown, this embodiment provides a device for adjusting an assembled truss beam structure, which includes a first adjustment mechanism 1 and a second adjustment component 2. A plurality of first adjustment mechanisms 1 are provided, and the plurality of first adjustment mechanisms 1 are arranged at intervals along the first direction. Among two adjacent first adjustment mechanisms 1, one is used to connect the upper chord 100 of the truss beam, and the other is used to connect the lower chord 200 of the truss beam. The upper chord 100 of the truss beam and the lower chord 200 of the truss beam are arranged at intervals along the second direction. The first adjustment mechanism 1 is configured to adjust the self-width of the upper chord 100 of the truss beam and the lower chord 200 of the truss beam respectively along the third direction. A second adjustment component 2 is provided between each two adjacent first adjustment mechanisms 1, and the two ends of the second adjustment component 2 are respectively rotatably connected to the adjacent first adjustment mechanisms 1. When the first adjustment mechanism 1 adjusts the width of the upper chord 100 of the truss beam and the lower chord 200 of the truss beam along the third direction, the second adjustment component 2 can adjust the spacing between the upper chord 100 of the truss beam and the lower chord 200 of the truss beam along the second direction.

[0034] In this embodiment, a plurality of first adjustment mechanisms 1 are provided, and the plurality of first adjustment mechanisms 1 are arranged at intervals along the first direction. Among two adjacent first adjustment mechanisms 1, one is used to connect the truss beam upper chord 100, and the other is used to connect the truss beam lower chord 200, so as to meet the installation requirements of the truss beam upper chord 100 and the truss beam lower chord 200. The truss beam upper chord 100 and the truss beam lower chord 200 are arranged at intervals along the second direction. Compared with manual operation by construction personnel, the first adjustment mechanism 1 can more accurately adjust the width of the truss beam upper chord 100 and the truss beam lower chord 200 respectively along the third direction, thereby improving the installation accuracy. A second adjustment component 2 is provided between each two adjacent first adjustment mechanisms 1, and the two ends of the second adjustment component 2 are rotatably connected to the adjacent first adjustment mechanisms 1. When the first adjustment mechanism 1 adjusts the width of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction, the second adjustment component 2 can adjust the spacing between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction, thereby realizing the flexible adjustment of the spacing between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction, shortening the construction period and improving the overall construction efficiency. Through the above-mentioned settings, the device for adjusting the assembled truss beam structure of this embodiment can efficiently and conveniently adjust the installation spacing of the truss beam, and the installation accuracy rate is higher.

[0035] It should be noted that, in this embodiment, the first direction and the third direction are both horizontal directions and perpendicular to each other, and the second direction is a vertical direction. In other embodiments, the above directions can be adjusted according to the actual installation requirements of the beam body, and no excessive restrictions are made here.

[0036] The specific structure of the device for adjusting the assembled truss beam structure is described below:

[0037] Specifically, Figure 1-Figure 3As shown, the first adjustment mechanism 1 includes a guide assembly 11, a sliding assembly 12 and a locking assembly 13. Two sliding assemblies 12 are provided, and the two sliding assemblies 12 are respectively slidably arranged on the guide assembly 11 along the third direction, ensuring that the sliding assembly 12 can maintain linear motion when sliding along the third direction, avoiding deviation or shaking, thereby ensuring the accuracy of adjustment. The truss beam upper chord 100 includes two first chord rods 101 spaced apart along the third direction, and the truss beam lower chord 200 includes two second chord rods 201 spaced apart along the third direction. For the first adjustment mechanism 1 connected to the truss beam upper chord 100, the two sliding assemblies 12 can be respectively connected to the two first chord rods 101, and the sliding assembly 12 slides relative to the guide assembly 11, thereby adjusting the spacing between the two first chord rods 101 along the third direction, thereby accurately adjusting the width of the truss beam upper chord 100 along the third direction. For the first adjustment mechanism 1 connected to the lower chord 200 of the truss beam, the two sliding components 12 can be connected to the two second chord rods 201 respectively, and the locking component 13 can lock the sliding component 12 on the guide component 11. The sliding component 12 slides relative to the guide component 11, thereby adjusting the spacing between the two second chord rods 201 along the third direction, thereby accurately adjusting the width of the lower chord 200 of the truss beam along the third direction.

[0038] Specifically, Figure 2 and Figure 3 As shown, in this embodiment, the sliding assembly 12 includes two clamping plates 121, which can be interlocked and detachably connected to each other, and the first chord 101 and the second chord 201 can be clamped between the two clamping plates 121, and the clamping plates 121 abut against the first chord 101 and the second chord 201, ensuring that the first chord 101 and the second chord 201 will not shake or fall off during the adjustment process. In other embodiments, the sliding assembly 12 includes a clamping block, which is clamped on both sides of the first chord 101 and the second chord 201, that is, the specific structure of the sliding assembly 12 is not limited.

[0039] More specifically, if Figure 3 As shown, in this embodiment, a groove is provided on the clamping plate 121. When the two clamping plates 121 are buckled with each other, the two grooves face each other and form a connecting groove, so that the first chord 101 and the second chord 201 can be inserted into the connecting groove. Bolts are inserted into the two clamping plates 121 and screwed to nuts, so that the two clamping plates 121 can be clamped on both sides of the first chord 101 and the second chord 201, thereby improving the connection stability of the overall structure. Among them, the groove is U-shaped, as long as it is adapted to the shape of the first chord 101 and the second chord 201, and the specific shape of the groove is not too much limited here. In other embodiments, the two clamping plates 121 are detachably connected by buckles, and the specific detachable connection method of the above components is not too much limited here.

[0040] More specifically, Figure 1 and Figure 3 As shown, an ear plate is also provided on the clamping plate 121, a through hole is opened on the ear plate, a connecting piece is passed through the through hole, one end of the connecting piece is locked on the ear plate by a nut, and the other end is configured to be rotatably connected to the second adjustment component 2 to ensure rotational cooperation between the second adjustment component 2 and the clamping plate 121, so as to facilitate the adjustment of the spacing between the upper chord 100 of the truss beam and the lower chord 200 of the truss beam.

[0041] Specifically, Figure 3 As shown, the guide assembly 11 includes two guide plates 111, and the two guide plates 111 are spaced apart along the second direction between the two sliding assemblies 12. Two slots 122 are provided on the sliding assembly 12, and the two slots 122 are both extended along the third direction and slideably matched with the two guide plates 111 one by one. Through the sliding connection between the slots 122 and the guide plates 111, the sliding assembly 12 can slide smoothly along the third direction relative to the guide assembly 11, thereby adjusting the spacing between the two first chord rods 101 and the spacing between the two second chord rods 201, and the adjustment is more convenient and flexible.

[0042] More specifically, if Figure 2 and Figure 3 As shown, in this embodiment, the guide plate 111 is provided with a slide groove 1111 extending along the third direction, and the locking assembly 13 includes a bolt member 131 and a nut member 132. The bolt member 131 can be inserted into the clamping plate 121 of the sliding assembly 12 and the slide groove 1111, and is threadedly connected to the nut member 132, so that the sliding assembly 12 and the guide plate 111 are firmly connected. Since the bolt member 131 can slide in the slide groove 1111 along the third direction, the relative position between the sliding assembly 12 and the guide plate 111 along the third direction is adjusted. When the sliding assembly 12 is adjusted to the desired position, the nut member 132 is rotated to gradually approach and tightly abut against the surface of the guide plate 111, thereby generating sufficient clamping force, that is, the nut member 132 abuts against the guide plate 111, and the sliding assembly 12 can be locked on the guide plate 111. This locking method is not only simple and reliable, but also convenient for quick installation and disassembly. Through the above arrangement, the position of the sliding assembly 12 relative to the guide assembly 11 can be adjusted, thereby achieving the width adjustment and fixation of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction.

[0043] More specifically, in other embodiments, the locking assembly 13 includes a screw, a nut and a locking pin. The screw is inserted into the sliding assembly 12 and the slide groove 1111. The screw slides in the slide groove 1111 along the third direction to adjust the relative position of the sliding assembly 12 relative to the guide plate 111. When the sliding assembly 12 slides to the desired position, the two ends of the screw are screwed to the nut so that the nut presses against the guide plate 111, and the locking pin is inserted into the openings at the two ends of the screw to prevent the screw from rotating relative to the nut, thereby achieving the locking effect between the sliding assembly 12 and the guide assembly 11. It can be understood that there is no limitation on the specific structure of the locking assembly 13, as long as the above-mentioned functions can be achieved.

[0044] Specifically, Figure 1 and Figure 4 As shown, the second adjustment component 2 includes two connecting rods 21, and the two connecting rods 21 are cross-arranged between two adjacent first adjustment mechanisms 1 and are rotationally connected at the intersection axis. The two ends of the connecting rods 21 are rotationally connected to the adjacent first adjustment mechanisms 1 respectively. When the first adjustment mechanism 1 adjusts the width of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction, it can drive the connecting rod 21 to rotate around the intersection axis. Through the cross-arrangement and rotational connection of the two connecting rods 21, the second adjustment component 2 can cooperate with the adjacent first adjustment mechanism 1 to jointly realize the width adjustment of the truss beam upper chord 100 and the truss beam lower chord 200 in the third direction, and the spacing adjustment between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction, thereby improving the flexibility and adaptability of the entire adjustment device and ensuring the stability and accuracy of the adjustment process.

[0045] Specifically, Figure 4 As shown, one of the two connecting rods 21 is provided with a first groove 211, and the other is provided with a second groove 212. The shape and size of the second groove 212 are adapted to the first groove 211, and can be accurately embedded in the first groove 211. The second groove 212 can abut against the first groove 211, so that the two connecting rods 21 are located in the same plane. When the first adjustment mechanism 1 starts to adjust the width of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction, the connecting rod 21 will rotate accordingly. Due to the close fit between the second groove 212 and the first groove 211, the rotational movement of the connecting rod 21 is smooth and controllable, thereby avoiding adjustment errors caused by misalignment or shaking.

[0046] More specifically, a rotating shaft 213 is provided in the first groove 211, and the extension direction of the rotating shaft 213 is parallel to the extension direction of the cross axis. The second groove 212 is rotatably connected to the rotating shaft 213, ensuring that the second groove 212 can stably rotate around the extension direction of the rotating shaft 213, so that the two connecting rods 21 can realize the rotation around the cross axis. The second adjustment component 2 also includes a limiter 22, which is arranged on the rotating shaft 213 so that the second groove 212 is located between the rotating shaft 213 and the first groove 211, thereby limiting the movement range of the second groove 212 on the rotating shaft 213 to prevent it from excessively rotating or disengaging from the rotating shaft 213. Among them, the limiter 22 is a nut or a sleeve, which is screwed to one end of the rotating shaft 213 through the limiter 22, thereby playing a role in limiting the second groove 212 and preventing the two connecting rods 21 from disengaging from each other during the rotation process.

[0047] More specifically, Figure 4 As shown, the end of the connecting rod 21 is threaded with a connecting ear plate 214, so that the construction personnel can easily remove the connecting ear plate 214 from the connecting rod 21 when necessary for maintenance, replacement or adjustment. The connecting ear plate 214 is configured to be rotatably connected to the first adjustment mechanism 1, so that the connecting rod 21 can flexibly follow the first adjustment mechanism 1 to move during the adjustment process, while maintaining a stable connection state. Among them, due to the threaded connection between the connecting ear plate 214 and the connecting rod 21, when the connecting ear plate 214 rotates relative to the connecting rod 21, the extension length of the connecting ear plate 214 relative to the connecting rod 21 can be adjusted to adapt to the connection between the first adjustment mechanisms 1 with different spacings, meet the installation operation of the truss beam, and have stronger adaptability.

[0048] Specifically, Figure 1 As shown, along the first direction, the extension directions of two adjacent second adjustment components 2 are set at an angle, that is, between the first adjustment mechanisms 1 at both ends of the first direction, multiple second adjustment components 2 are set in a wave-like bending manner. When the first adjustment mechanism 1 adjusts the width of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction, the second adjustment components 2 can shrink or stretch, thereby adjusting the spacing between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction. It can be understood that, as Figure 1-Figure 4As shown, when the clamping plate 121 slides relative to the guide plate 111 along the third direction, it can drive the two first chords 101 to move toward or away from each other, and the two second chords 201 to move toward or away from each other, thereby realizing the self-width adjustment of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction. At the same time, the movement of the clamping plate 121 will cause the connecting rod 21 to rotate around the cross axis, so that the spacing between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction changes, that is, when the self-width of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction increases, the spacing between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction decreases, and when the self-width of the truss beam upper chord 100 and the truss beam lower chord 200 along the third direction decreases, the spacing between the truss beam upper chord 100 and the truss beam lower chord 200 along the second direction increases.

[0049] It should be noted that when the device for adjusting the assembled truss beam structure is installed on the truss beam upper chord 100 and the truss beam lower chord 200, gaskets are provided at the connection between the bolts and nuts to improve the connection stability of each component and prevent loosening.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
