[0026] Example 1:

[0027] like Figures 1 to 5 The diagram illustrates an embodiment of a support structure for truss assembly according to this utility model. It includes multiple support units, each comprising a base, a support frame, an adjusting frame 5, and multiple fixing components. The support frame is connected to the base, and the adjusting frame 5 is movably connected to the support frame to adjust its height. The multiple fixing components are respectively connected to the base and the adjusting frame 5 to cooperate in fixing the truss. Preferably, the support frame is vertically connected to the base, and the adjusting frame 5 is vertically arranged to the support frame. The adjusting frame 5 is height-adjustable and detachably connected to the support frame, providing better support for the upper chord of the truss. The fixing components installed on the adjusting frame 5 and the base provide better fixation for the upper and lower chords of the truss.

[0028] On the other hand, the method of using this utility model includes the following steps:

[0029] In one application scenario, multiple support units form a group, and the multiple support units are spaced apart along the length of the truss. The height of the corresponding adjustment frame 5 is adjusted and the truss is fixed by a fixing component.

[0030] In another application scenario, multiple support units are divided into two groups, which are respectively arranged opposite each other on both sides of the truss. Preferably, the number of support units in each group is the same so that the multiple support units are symmetrically distributed on both sides of the truss. The multiple support units in each group are spaced apart along the length of the truss. The height of the corresponding adjustment frame 5 is adjusted and the truss is fixed by the fixing components. The fixing components on the corresponding adjustment frames 5 on opposite sides can form an inclined support surface, which can be better used for the assembly of trusses of different specifications, such as the support and fixation when assembling triangular trusses or irregular trusses.

[0031] In this embodiment, the base includes a first base 1 and a second base 2, the first base 1 and the second base 2 are connected, the support frame is connected to the first base 1, and the second base 2 and the adjusting frame 5 are located on the same side of the support frame. Preferably, the first base 1 and the second base 2 are arranged vertically in a T-shape and are detachably connected to each other. The base also includes a first connecting plate 11 and a first bolt assembly. The first base 1 and the second base 2 are both made of H-beams. The web of the first base 1 is perpendicularly fixed to the first connecting plate 11, and the fixing method can be welding. The first connecting plate 11 is detachably connected to the web of the second base 2 through at least one set of first bolt assemblies. The support frame is detachably connected to the corresponding flange of the first base 1.

[0032] In this embodiment, the support frame includes a vertical support 3, which is connected to the base. The vertical support 3 has an adjustment hole group for detachable connection with the adjustment frame 5. Preferably, the adjustment hole group includes a plurality of adjustment holes spaced apart along the length of the vertical support 3. The support frame also includes a second connecting plate 31 and a second bolt assembly. The vertical support 3 is also made of H-beam steel, and its end used to connect to the base is fixed to the second connecting plate 31. The fixing method can be welding. The second connecting plate 31 is detachably connected to the corresponding flange plate of the first base 1 through at least one set of second bolt assemblies. The flange plate of the vertical support 3 used to install the adjustment frame 5 has an adjustment hole group. The support unit also includes a third connecting plate 51, positioning bolts, and positioning nuts. The adjustment frame 5 is also made of H-beam steel, and the end of the adjustment frame 5 used to connect to the vertical support 3 is fixed to the third connecting plate 51. The third connecting plate 51 has fixing holes corresponding to the bolt hole group for inserting positioning bolts. The positioning bolts can be connected to the positioning nuts to fix the height of the adjustment frame 5.

[0033] In this embodiment, the support frame further includes at least one diagonal brace 4, with both ends of each diagonal brace 4 connected to the vertical support 3 and the base, respectively. Preferably, both ends of the diagonal brace 4 are detachably connected to the web of the vertical support 3 and the corresponding flange of the first base 1, respectively, so that the diagonal brace 4 can better enhance the stability of the structure.

[0034] In this embodiment, the base and the adjusting frame 5 are slidably connected to their respective fixing components. Specifically, the upper flange of the second base 2 and the upper flange of the adjusting frame 5 are both slidably connected to their respective fixing components.

[0035] In this embodiment, each fixing component includes two opposing clamping plates 6, each clamping plate 6 being slidably connected to a corresponding base or adjusting frame 5. Preferably, the clamping plates 6 are L-shaped and have corresponding holes. The upper flange plates of the second base 2 and the upper flange plates of the adjusting frame 5 both have elongated holes. The spacing and position of the two clamping plates 6 are adjusted to meet the requirements of truss support and positioning, and the corresponding holes are aligned with the elongated holes for fixing by inserting fixing bolts. The spacing between the two opposing clamping plates 6 is adjustable, which can better accommodate upper and lower chords of different diameters.

[0036] In this embodiment, the support unit further includes at least one height adjustment pad 7, which is disposed between the fixing component and the adjusting frame 5, and the height adjustment pad 7 is detachably connected to the adjusting frame 5. The height adjustment pad 7 is also provided with an adjustment elongated hole that matches the elongated hole on the adjusting bracket 5 for inserting fixing bolts. Construction personnel can install one or more height adjustment pads 7 with appropriate thickness as needed to improve the truss assembly accuracy.

[0037] In this embodiment, the components are detachably connected by bolts, which facilitates disassembly and transportation. The number of support units can also be flexibly increased or decreased according to site requirements. The adjustable structure can better improve construction flexibility and ensure construction efficiency.

[0038] The specific usage process of this embodiment is as follows:

[0039] Determine the required number of support units and perform preliminary assembly of each support unit;

[0040] According to the dimensions of the truss drawings, mark the truss projection lines on the ground of the assembly site and lay out the corresponding support units. Usually, adjacent support units are arranged at a standard interval of 4.5 meters along the length of the truss. At the same time, care should be taken to avoid the nodes and web members of the truss to ensure that the truss structure will not be disturbed during construction.

[0041] The height of the adjusting frame 5 is initially adjusted by adjusting the hole group to ensure that the adjusting frame 5 is not higher than the design height of the upper chord of the truss, so as to ensure that the adjusting frame 5 can support the upper chord of the truss; the height adjustment plate 7 of the appropriate specification is selected according to the design size of the truss to achieve millimeter-level positioning.

[0042] The upper and lower chords of the truss are placed on the second base 2 and the adjustment frame 5 respectively. The position of the clamping plate 6 is adjusted and fixed through the pre-drilled holes on the second base 2 and the adjustment frame 5 to ensure that the upper and lower chords are firmly fixed, providing a stable foundation for subsequent assembly work.

[0043] After the truss assembly is completed, multiple support units are dismantled or moved to the next work site to prepare for the next round of truss assembly.

[0044] Example 2:

[0045] like Figure 6 As shown, in this embodiment, the adjustment hole group includes at least one set of composite adjustment holes. The composite adjustment holes include a movable elongated hole 32 arranged along the length of the vertical support 3 and a plurality of vertically arranged locking holes 33. The plurality of locking holes 33 are all located on the same side of the movable elongated hole 32 and each locking hole 33 is connected to the movable elongated hole 32.

[0046] When adjusting the height of the adjusting bracket 5, the bolts and nuts in the second bolt assembly can be loosened, allowing the bolts in the second bolt assembly to move vertically along the moving elongated hole 32 to the appropriate height, and then move laterally into the locking hole 33 and lock with the corresponding nut. This avoids the need to remove the nut in the second bolt assembly before adjusting the bolt position, thus improving the efficiency of installation and disassembly.

[0047] This embodiment can be applied to the assembly needs of trusses of different specifications, can ensure the quality of truss assembly, and is easy to install and disassemble. It has a simple structure, low processing cost, and can be reused.
