Details of the Example As shown in FIG. 1, a metal roof truss 10 includes a lower chord element 12, and a pair of upper chord elements 14, 10 are connected to opposite ends thereof. The metal roof truss 10 also includes several elongated reinforcing bars, such as 18, 20, whose opposite ends are connected to one of the lower chord element 12 and the upper chord element 14. In this embodiment, one of the reinforcing bars is a compression bar 18 and the other reinforcing bar is a force bar 20. The metal roof truss 10 of this embodiment is substantially rectangular in which adjacent ends of the upper chord members 14, 16 are connected at a top connection point 22. The opposite ends of the upper chord elements 14, 16 are at respective heel portions, such as 24, which are connected to the opposite ends of the lower chord element 12. However, it should be understood that the shape of the metal roof truss structure may be different from that described, but still within the scope of the present invention. For example, the bottom chord may include a chord element, and similarly, the pair of upper chord elements may extend to several Chords. As shown in Figure 2, the lower and upper strings 12 to 16 and reinforcing bars, such as 18, 20, are cold-formed from steel bars "including a long strip 26 and a relatively paired flange, such as 28 and 30" -Groove section profile. The flanges 28, 30 include free edges and edges that bend outwardly from each other. The bottom and top of the strings 12 to 16 and the reinforcing bars 18 and 20 are made of steel bars of a relatively light gauge and a thickness of substantially 0.75 mm, such as those sold in the Australian market. According to a feature of Ben Ming, in the configuration of the opposite ends of the reinforcing bars such as 18 and 20, the 'reinforcing bars 18 or 20 each connect one of the lower string 12 and the upper string 14 respectively. The paper size is suitable for money_ 绪 准 (⑽ 514693 A7 __________B7_ V. Description of the invention (6) This feature is clearly shown in Figure 3. According to an embodiment, the contact or connection of the flange 28 '30 of the compression strip is to increase the roof The structural performance of the truss 10. The lower and upper chords 12 to 16 and the reinforcing bars 18, 20 are arranged on the same plane, and each of the reinforcing bars 18, such as 26 and chord elements, such as 12, are at the same height. One more important thing is that the flange of the compression strip 18, such as 28, 30, is cut on the opposite end or pre-formed to engage or contact the strings 12 and 14, respectively. The flange, such as 28, 30 ,, The depth 〃 depends on the orientation of the reinforcing bars relative to the string elements, such as 18, 20. The reinforcing bars, such as 18, 20, and the lower or upper string elements 12 to 16 include pre-formed holes, such as 32, 34, which are aligned with each other To fix the roof truss 10. With a fairly rough thread, such as screw fasteners sold under the trademark TRUSSTITE in the Australian market, engage the alignment holes, such as 32 or 34, to fix the reinforcement bar to the lower chords 18 and 20. Alignment holes, such as 32, 34 pre-drilled holes in the steel bar, and then rolled to form a chord element Such as 12 or reinforced strips, such as 18. As shown in Figure 4, the relative flanges of the upper chord element 14, such as 28 and 30 | are similarly preformed on one end to form the heel connection 24. The flanges 28 and 30 It is cut or pre-formed on the opposite end of the upper chord element 14. Among them, the flange _ ♦ · 28, 30 connects or contacts the lower chord 12. The lower and upper chords 12 and 14 also include pre-formed and aligned holes such as 38, which are formed by a TRUSSTITE or other fasteners are connected to fix the lower and upper strings 12 and 14. The connection or contact of the flanges 28, 30 of the upper string 14 with a corresponding flange of the lower string 12, such as 28, also increases the structural function of the roof truss 10. The depth of the cut-out or pre-formed flanges 28, 30 of the upper chord 14 or 16 is determined by the configuration of the roof truss 10, especially the angle of the upper chord 14 or 16 relative to the lower chord element 12.

Description of the Invention (7) " '-, Concave additions The groove section chords 12 to 16 and the contour of the wearing surface such as ^ and the reinforced strip are asymmetric. For example, one of the opposite edges of 28 is opposite to the other flange, such as 30. The height is relatively low. The strips such as 12 and 8 are designed to be interconnected to form a chord or reinforced strip m to 16 with a closed cross section and / or the reinforced strips 18 and 2 () may include one or more longitudinally extending reinforcing ribs. Preferably, the reinforcing ribs are formed on a strip 26 having a grooved section. Another feature according to the present invention is a method of forming elongate reinforcing strips such as 18 and 20 and string elements such as 12 to 16. As shown in Fig. 5, this embodiment of the present invention involves preforming a pair or several pairs of opposite dents on the long steel bar 40, such as 36,38. Opposite pairs of indentations, such as a fragile connection at the junction of adjacent reinforcement strips such as 18, 20 in this embodiment, 36,38. The shape of the pre-formed relative indentations 36 and 38 makes: 毗邻 The adjacent reinforcing strips 18 and 20 of this embodiment can be manually separated or repeatedly bent to the adjacent strips after the cross-section rolling is formed. Separate; (ii) When the roof truss 10 is lifted, the opposite edges of the respective reinforcement strips 18 or 20 such as 28, 30 contact the lower chord 12 or the upper chord 16. In this embodiment, the relative indentations, such as 36 and 38, extend into strips such as 26 corresponding to the reinforcing strips 18 or 20. Thus, the strip 26 is sufficiently weakened at the junction of the reinforcing strips 18, 20 to allow the reinforcing strips 18 and 20 to be separated. However, the frangible joints are sufficiently strengthened to maintain the connection between adjacent metal roofs such as the reinforcement strips 18 and 20 during the roll forming process. Therefore, different members of the metal roof truss, such as the reinforcing strips 18, 20 can be made into a beam. For example, reinforced strips such as 18, 20 and other reinforced strips of roof truss 10 can be made into a single paper with a standard of China Paper (CNS) A4 (210X297 public love) -10-514693 'V. Description of the invention ( 8) The bundles are separated before the metal roof truss 10 is lifted. Similarly, in the case of relatively small trusses, for example, the upper and lower chords of 12 to 16 can be connected into a bundle. This increases the speed of manufacturing metal roof truss members, reduces the risk of missing components, and facilitates the lifting of metal roof trusses such as 10. : Pre-marked strings, such as 12 to 16 and reinforcement strips 18 and 20 are also pre-punched-first add holes to facilitate the next assembly. In this embodiment, firmware holes such as 32 and 34 are formed on the opposite ends of the respective reinforcing bars such as 18 and 22, and in this embodiment > mutually aligned firmware holes are formed on the bottom chord 12. Fixing holes, such as 32 and 34, are pre-formed on individual roof truss members, such as 26, when steel bars such as 40 are pre-dented. Then, the strip 40 previously nicked and perforated in advance is formed in the cross section of the groove as shown in Fig. 2 by cold rolling. The roll former is relatively inexpensive, and has no features, and the steel strip can be formed in advance with scoring and pre-punching. This will ensure that when the metal roof truss, such as 10, is fixed and raised, the flanges of the reinforcement strips 18 and 20, such as 28, 30 will lean against the lower and upper chords, 14, respectively. Figure 6 shows a top plate 42 included on the top connection 22. The top plate 42 is elongated and includes a reinforced flange 44 along one of its longitudinal edges. The strengthening flange 44 is defined by a lip, and the lip is bent at a right angle to the top plate 42. The top plate 42 is screwed or otherwise fixed to the strip adjacent to the top chords 14,16. The roof panel 42 is generally oriented toward the reinforcing flange 44 positioned between the roof chords 14 and 16 and faces the interior of the roof truss 10. The top plate 42 fits up to 40 degrees. Range of the top connection. The top plate 42 includes a plurality of pre-formed holes, such as 46, configured to hold the top plate 42 to the upper chord members η and 12 and a strip such as 20. Figure 7 is related to the design and manufacture of the metal roof truss as described above. This paper is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). 11 A7 ----- £ 1. Description of the invention (9) Asynchronous 骡The flow chart of the block diagram is as follows: (1) Design the data input structure to form a processor that outputs control data to a device that is pre-added with nicks and holes; (ii) feed the steel bar in advance A device for scoring and holes, which forms a steel bar according to the control data of the processor; (ill) fixed details generated and output by the processor are printed on the steel bar with scoring and holes in advance; and (iv) the steel bar It is rolled by a conventional inexpensive roll former. The fixing details are preferably printed on the members of the string 12 or reinforcement strips to which the details are applied. For example, the reinforcement strip 18 may include fixing details or instructions, where it requires two pieces of firmware, each end of which is fixed to a properly designed one. Upper and lower chords. In addition, the roof street structure can include valid data of the column assembly checked by a third party, and the component marking is also assisted by the complete design of the roof truss and its combined speed. The processor includes software, which A CAD, operating in the environment, and determine the better configuration of the metal roof truss according to the dimensions and weight data related to the building structure. In addition, the program accurately determines the angle of different roof street frame components. The requirements of dents and holes are added in advance. This point can particularly ensure that 'for example, the flanges of the reinforcing strip are in contact with the upper and lower strings. 2. I. Those skilled in the art can understand that the invention can be modified differently. For example, Yao Yao The structural benefits of connecting the opposite flanges of the string element can be achieved, and the wearing profile of the reinforcing strip and / or the string element can be changed. As long as the field of the metal roof street frame is adjacent to the adjacent member, such as strong A fragile connection is provided between the strips, which can change the pre-scores added on the steel strips.
