PURPOSE:To enable branch line blocks to be carried without bulking easily and also make them withstand great loads by a method in which a branch line bar having a connecting ring on its upper end is fixed to a base plate with nuts, and three resisting plates matching the regulating ribs of the base plate and a presser plate are provided. CONSTITUTION:A pair of coupling holes 8 are fitted with plural pairs of projections 11 on the upside of a base plate 10, and resistor plates 5 are set orthogonally to the base plate 10. The notches 16 formed on both side lower edges of the presser plate 14 are coupled orthogonally to nearly central upper part of the resistor plates 5. The threaded portion 3 of the branch line bar 1 is thrust through the hole 15 of the plates 14 and connected with nuts 13 fixed to the back side through the central hole 12 of the plate 10. Necessary space for the blocks prior to assembling can thus be greatly reduced, and the blocks can withstand great loads. |
