Description

Truss structure

This creation refers to a truss structure, which mainly refers to a structure with better support stability and manufacturing convenience.

The conventional truss is shown in Fig. 5, mainly composed of an upper chord 1', a lower chord 2', and a plurality of webs 3'. The upper and lower chords 1', 2'are arranged in parallel, and the adjacent web 3 'Different oblique directions are provided between the upper and lower chords 1', 2', and the two ends are welded to the bottom surface of the upper chord 1'and the top surface of the lower chord 2', and the position of one end of the adjacent web 3'corresponds to Form a number of consecutive triangular arrangement structure.

When manufacturing the aforementioned truss, the upper and lower chords 1', 2', and the web 3'must be cut before welding, and after welding, pickling and galvanizing procedures will be performed, and the welding point will be incomplete. After galvanizing, the surface treatment must be post-processed, and if the truss exceeds the length of the pickling tank or galvanizing tank (not shown), the truss must be cut again, and then processed and combined after pickling and galvanizing. Inconvenience and high cost are missing.

Moreover, the welding point of the end of the adjacent web 3'and the upper and lower chords 1', 2'are not in the same position, causing the upper chord 1'to produce a force component in the longitudinal direction when the upper chord 1'is stressed. The average force from the 3'component of the web to the 2'of the lower chord results in a loss of reduced stability of the truss.

The purpose of this creation is to provide a structure with better structural strength and convenient manufacturing.

This creation includes an upper chord, a lower chord, and a plurality of abdominal rods. The upper chord is a straight bar. The lower chord is a straight bar. The upper and lower chords are arranged in parallel. The upper chord is aligned parallel to the left. , The first and second sides in the right direction, the lower chord corresponds to the third and fourth sides in the left and right directions; and one of the plurality of abdominal rods is diagonal to its two ends and the upper and lower chords respectively One and three sides are in contact with each other, and the other abdominal rod adjacent to the abdominal rod has a different oblique direction and the two ends are respectively in contact with the second and fourth sides of the upper and lower chords, and the two adjacent abdominal rods One end corresponds to the position, and is hinged by a hinge, and the number of web rods are sequentially combined along the length direction of the upper and lower chords to form a truss with a number of triangular structures.

Further, the hinge member penetrates the end of the adjacent web rod and the upper chord or lower chord hinge combination.

Further, the upper and lower chords and the webs may be pre-plated or pre-coated profiles without post-surface treatment, and the upper chord, the lower chords and the webs may be square bars, C-shaped bars, ㄇ-shaped bars or round bars.

This creation does not need to be welded by articulation, and the upper and lower chords and webs do not need to be pickled and galvanized surface treatment, which can have better manufacturing convenience and texture, and this creation is adjacent to the end of the web It is set at the same point, so that the force of the upper chord can be averaged to the lower chord through the abdominal rod, which can have better support and stability.

Please refer to Figures 1~3. This creation includes an upper chord 1, a lower chord 2, and a plurality of webs 3. The upper and lower chords 1, 2 and web 3 are pre-plated or pre-coated profiles without post-treatment, It can also be a square rod, C-shaped rod, ㄇ-shaped rod, round rod or other profiles.

The upper and lower chords 1 and 2 are straight bars and are arranged in parallel with the upper and lower sides. The upper chord 1 has first and second sides 11, 12 corresponding to the left and right directions, and the lower chord 2 corresponds to the left and right directions With third and fourth sides 21,22.

One of the plurality of abdominal rods 3 is diagonal and the two ends are in contact with the first and third sides 11, 21 of the upper and lower chords 1, 2 respectively, and the other abdominal rod adjacent to the aforementioned abdominal rod 3b 3a presents different oblique directions and the two ends are in contact with the second and fourth sides 12, 22 of the upper and lower chords 1, 2 respectively, and correspond to the position of one end of the two adjacent webs 3a, 3b, and are hinged 4. Insert the ends of the adjacent webs 3a, 3b and the upper chord 1 or the lower chord 2 into a hinge, and sequentially combine the webs 3 along the length of the upper and lower chords 1, 2 to form a truss with a triangular structure.

This creation is combined by articulation without welding, and the upper and lower chords 1, 2 and web 3 do not need to be pickled and galvanized surface treatment, which can have better manufacturing convenience and texture, as shown in Figure 4 It is shown that the ends of the adjacent webs 3 in this work are set at the same point, so that the force of the upper chord 1 can be equally distributed to the lower chord 2 via the web 3, which can have better support and stability.

Therefore, as mentioned above, this creation can enhance the truss with better manufacturing convenience and support stability, and can be suitable for greenhouses or other occasions. The foregoing embodiment is an example of creation, not a limitation of this creation. The equivalent change of the spirit should also fall within the scope of this creation.
