DETAILED DESCRIPTION
[0035] FIGS. 1 to 11 showcase the all-thread multibracket, meticulously designed to ensure the secure mounting of HVAC equipment on walls or ceilings during installation. Crafted from high-quality metal, this bracket features a precisely determined thickness, guaranteeing strength and reliability. Its ingenious design enhances its functionality and versatility.
[0036] Our all-thread multibracket can be made from a 3 mm-thick rectangular steel plate. The plate measures 103 mm in length and 45 mm in width. To create the shape of the multibracket, one can make two cuts on the plate from the two 45 mm shorter sides of the plate at the top and the bottom. The two cuts are positioned 25 mm from the left longer side of the plate. The two cuts measure 25 mm long. After these cuts, the two sections on the left side of the cuts (one on the top and the other on the bottom) are bent 90 degrees to the front, forming a U-shaped structure that is 53 mm in width and 25 mm in height. On the right side of the cut, the top section is bent 90 degrees to the back. This results in the right side of the steel plate forming an L-shaped structure that is 78 mm in height and 25 mm in width.
[0037] There are 3 special holes (1, 7 and 9) in FIGS. 1-3 that are 12 mm in diameter. These 3 holes make up two pairs of perpendicular holes (1-7 and 7-9) and one pair of concentrical holes (1-9). An M10 standard nut is welded on top of each hole. However, other hole and nut sizes can also be present on the multibracket as well for different requirements. The standard nut will be required to weld on the bracket. To avoid welding, standard nuts can be replaced by rivet nuts.
[0038] The multibracket is ingeniously designed with four M6 circular holes (3, 4, 5, 8 in FIG. 1) strategically placed to facilitate easy fixation to walls, beams, purlins, and timbers using screws, as depicted in FIGS. 8 to 11. Each circular hole has a diameter of 6 mm. These four holes are placed on the L-shaped structure of the multibracket. Hole 3 is on the horizontal section of the L-shaped structure and the other three holes (4, 5 and 8) are on the vertical section of the L-shaped structure. Specifically, hole 3 is at the centre of the horizontal section of the L-shaped structure. The other 3 holes (4, 5 and 8) are lined up 10 mm from the right longer edge of the vertical section of the L-shaped structure. From the bottom up, in order, hole 8 is 8 mm from the bottom edge of the vertical section of the L-shaped structure, hole 5 is 30 mm from hole 8 and hole 4 is 15 mm from hole 5.
[0039] Illustrated in FIG. 5, using its two concentrical nuts (2 and 10), the all-thread multibracket can be used to connect two threaded rods to form a rod with the expected length.
[0040] In FIG. 6, the all-thread multibracket demonstrates its exceptional utility by seamlessly connecting a threaded rod to a steel beam, offering a robust and dependable solution for structural support. An M10 bolt is connected to nut 2. An M10 threaded rod is connected to nut 10.
[0041] Illustrated in FIG. 7, the all-thread multibracket is used to connect a thread rod to a steel purlin, ensuring sturdy and reliable support. Similar to FIG. 6, nut 2 is connected to a M10 bolt and nut 10 is connected to a M10 threaded rod.
[0042] FIG. 8 showcases the all-thread multibracket's ingenuity as it effortlessly connects a threaded rod to the bottom of HVAC equipment, ensuring a secure and stable mounting solution. Two M10 threaded rods are connected to nuts 2 and 10.
[0043] Illustrated in FIG. 9, the all-thread multibracket is used to connect a threaded rod to a steel bar or timber stud. To use our all-thread multibracket in this case, first we place the multibracket to the edge of the timber stud with the L-part touch the surface of the timber stud. Second, we fix the multibracket to the timber stud by nailing or screwing the four holes (3, 4, 5 and 8 in FIG. 1) and the multibracket is ready to use. One or two threaded rods can be connected to nuts 2 and 10. As an example, we connect a threaded rod to nut 10 in FIG. 9.
[0044] Illustrated in FIG. 10, the all-thread multibracket is used to connect a threaded rod to the wall after cutting off the 25 mm bent part of the L shape. As a result, hole 3 is also removed from the multibracket. Three holes (4, 5 and 8) were screwed with M6 screws to fix the multibracket to the wall and then a threaded rod can be connected to nut 10. In FIG. 11, the all-thread multibracket serves its purpose by effectively connecting a threaded rod to the ceiling. The shorter part of the L-shape was removed, similar to FIG. 10. Three holes (4, 5 and 8) were screwed with M6 screws to fix the multibracket to the ceiling and then a threaded rod can be connected to nut 6.
