[0027] The following is a further detailed description of the specific implementation of the present utility model in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the related art, the truss has very high requirements on the placement of chords during processing. Adjacent chords need to be placed on the same horizontal plane and parallel to each other. However, the flatness of the workshop or construction site is difficult to grasp, and the conventional device for fixing the chords cannot adjust the height of the chords. It is difficult to meet the requirements for chord placement, resulting in inaccurate truss processing and affecting the normal use of the truss.

[0030] In view of this, if Figures 1 to 3 As shown, some embodiments of the utility model provide a truss fixing device, including a base 2 and a support cap 1; the support cap 1 is sleeved on the base 2, the support cap 1 and the base 2 are detachably connected, and the side of the support cap 1 away from the base 2 abuts against the chord 13.

[0031] In the above embodiment, the support cap 1 can be made of metal material, such as steel. Figure 1 In the direction shown, the cross-section of the support cap 1 in the horizontal direction is circular or rectangular. At the same time, the size of the end of the support cap 1 away from the base 2 is larger than the size of the end of the support cap 1 close to the base 2. The support cap 1 is sleeved on the upper end of the base 2 and can be slidably connected to the base 2 so that the support cap 1 can slide along the length direction of the base 2. At the same time, the support cap 1 can be detachably connected to the base 2 so that the support cap 1 can be connected to the base 2 at different heights. Further, on two adjacent chord rods 13, a plurality of support caps 1 and bases 2 are arranged below each chord rod 13, and each base 2 is sleeved with a support cap 1, as shown in FIG. Figure 2 and Figure 3 As shown, after the support cap 1 arranged above the base 2 is adjusted along the height direction of the base 2, the ends of all the support caps 1 close to the chord rod 13 are on the same plane and can be aligned with the base 2. Figure 1 The horizontal planes shown are arranged in parallel so that adjacent chord rods 13 are in the same horizontal plane, and the distance between two adjacent chord rods 13 can also be made consistent by setting the position of the base 2.

[0032] Optionally, the position requiring support can be determined by the chord 13, and a coordinate system can be established to obtain coordinate information of the position requiring support determined by the chord 13, and the placement position of each base 2 can be determined by the coordinate information, and then the chord 13 can be fixed by adjusting the height of the support cap 1.

[0033] Optionally, the height of the base 2 and the support cap 1 after being connected can be set between 0.5m and 1m. Exemplarily, the height of the base 2 and the support cap 1 after being connected can be set to 0.5m, 0.6m, 0.8m, 1m, etc., to facilitate construction workers to connect adjacent chords 13 through the web members 14.
