The specific embodiment

Please refer to Fig. 1, Fig. 2, common joists support of the present utility model, the carrier unit 1 identical by several structures is spliced to form, and carrier unit 1 is to be made of the front shell 11 that is square box shaped, rear portion housing 12 disjunctors, and the material of housing 11,12 can be plastics.The cross section of these front shell 11 gabarits is less than the cross section of rear portion housing 12 gabarits, one hyoplastron 111 is arranged on the leading flank of this front shell 11, on this hyoplastron 111 through hole 112 is arranged, have one horizontal ribbed 121 in the rear portion housing 12, this floor 121 has the wing plate longitudinally 122 of disjunctor towards a side of rear portion housing 12 tail end directions, on this wing plate 122 through hole 123 is arranged, one horizontal base plate 124 is arranged on the afterbody bottom surface of rear portion housing 12, this base plate 124 forms a groove 125 with the end face and the two sides of rear portion housing 12, and the cross section size of the cross section of this notch 125 and described front shell 11 is corresponding; This notch 125 aligns with the position of described front shell 11, has a cross section that projects upwards that is used for the tongued and grooved flooring piece to be "T"-shaped card article 126 on housing 12 end faces of described rear portion.

Please refer to Fig. 3, Fig. 4, amalgamation structure between each carrier unit 1 is: the position after the front shell 11 of carrier unit insert position adjacent the preceding in the notch 125 of carrier unit rear portion housing 12 afterbodys, the position after the hyoplastron 111 of carrier unit on through hole 112 and position adjacent hang with extension spring 2 between the through hole 123 on the carrier unit wing plate 122 the preceding.

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, on the two sides of rear portion housing 12 jagged 127.Its effect is to be used for cotton covered wire.

Please refer to Fig. 5, Fig. 6, the end face of rear portion housing 12 has the screw base 128 of disjunctor downwards, and screw base 128 is used to place screw or bolt, so just can carrier unit be fixed on the ground by screw or Luo bolt, and screw base 128 has counter sink 129.Counter sink 129 is a through hole, can be threaded, can be not threaded yet, counter sink 129 can make bolt head or head of screw not protrude in the end face of rear portion housing 12, keep rear portion housing 12 surfacings, thereby floor board block can be installed, during enforcement, the carrier unit that has screw base 128 can be used with the carrier unit with screw base not, just can be with the assembly overall fixed of carrier unit in ground.
