Description

Technical Field

[0001] The invention relates to a tube bundle, in particular to a U-shaped tube bundle structure and a forming method thereof which can simplify assembly, save labor time and process, and can be easily assembled and used. Background Art

[0002] In general, the bundles of multiple pipes (pipes can be water pipes or electric wire pipes, etc.) in a building have certain spacing requirements for fixing each pipe. Please refer to Fig.14 and Fig.15 As shown, the tube bundle 90 of the prior art includes: the tube bundle 90 includes two bent locking clips 91, a bolt 92 and a bolt 93, each locking clip 91 has: a square end 911, which has a notch 912 adjacent to it; and a rounded end 913, which is adjacent to one of the through holes 914. After the locking clips 91 are assembled, they are arranged on the support member 80 to form a tube body 70 in a clamped state. The notch 912 of each locking clip 91 is inserted from both sides of the open end of the support member 80, so that the notch 912 of each locking clip 91 is 12 is clamped on the two hooking parts 81 of the support member 80, and is pressed and installed on the side of the tube body 70 through each rounded end 913, and the connecting bolts 92 and the bolts 93 are passed through the through holes 914 of the two locking clips 91 to loosely limit the tube body 70 in the rounded ends 913. When the tube body 70 is confirmed to be moved to the correct position, the bolts 92 and the bolts 93 are tightened to make the notch 912 hooked in each hooking part 81 of the support member 80, and the rounded ends 913 of each locking clip 91 press the tube body 70 to fix it and limit its sliding.

[0003] Although the tube bundle 90 of the prior art has a fixed limiting tube body 70 when in use, it is inconvenient for the operator to install it because the notches 912 of each locking clip 91 need to be inserted from both sides of the open end of the support member 80 for installation, or the notches 912 of each locking clip 91 need to be rotated at a 45-degree angle to avoid being inserted into the hooks 81 of the support member 80. When there are too many tube bodies in the building, it will cause inconvenience to the operator during installation. Summary of the invention
