Abstract

Claims (45)

1. A splice plate assembly for connecting at least two cable trays to effect an angle transition comprising:

a splice plate configured to connect inner side rails of the at least two cable trays to form an inside corner, the splice plate including:

an intermediate member;

first and second bendable members connected by the intermediate member at a joint angle; and

first and second mounting members connected to the first and second bendable members via first and second ribs, respectively;

a bendable strap configured to connect outer side rails of the at least two cable trays to form an outside corner; and

a rung adapted to be connected between the splice plate and the bendable strap.

2. The splice plate assembly of claim 1 , wherein the first and second ribs provide a bending mechanism of the splice plate.

3. The splice plate assembly of claim 1 , wherein each of the first and second bendable members defines a plurality of bendable member openings to facilitate easy bending of the splice plate.

4. The splice plate assembly of claim 1 , wherein each of the first and second mounting members defines a plurality of mounting member holes through which connectors could be inserted to affix the splice plate to the inner side rails of the at least two cable trays.

5. The splice plate assembly of claim 1 , wherein the intermediate member defines a plurality of intermediate member holes through which connectors could be inserted to secure the rung to the splice plate.

6. The splice plate assembly of claim 1 , wherein the first and second bendable members, the first and second mounting members, and the intermediate member have equal heights.

7. The splice plate assembly of claim 1 , wherein the first and second bendable members, the first and second mounting members, and the intermediate member are substantially rectangular in form.

8. The splice plate assembly of claim 1 , wherein the bendable strap defines a plurality of bendable strap holes through which connectors could be inserted to affix the bendable strap to the outer side rails of the at least two cable trays.

9. The splice plate assembly of claim 1 , wherein the bendable strap is a flexible substrate.

10. The splice plate assembly of claim 1 , wherein the bendable strap is substantially rectangular in form.

11. The splice plate assembly of claim 1 , wherein the rung includes:

first and second end plates; and

an elongated channel configured to be connected between the first and second end plates.

12. The splice plate assembly of claim 11 , wherein each end of the channel is connected to the first and second end plates by welding.

13. The splice plate assembly of claim 12 , wherein each of the first and second end plates includes a plurality of embossments such that they can fit into the channel and hold it while the welding is performed.

14. The splice plate assembly of claim 11 , wherein:

the intermediate member defines a plurality of intermediate member holes through which connectors are insertable to secure the rung to the splice plate;

the bendable strap defines a plurality of bendable strap holes through which connectors are insertable to affix the bendable strap to the outer side rails of the at least two cable trays; and

each of the first and second end plates defines an end plate hole that can be aligned with one of the plurality of intermediate member holes or one of the plurality of bendable strap holes to connect the rung to the splice plate and the bendable strap.

15. The splice plate assembly of claim 11 , wherein a plurality of channel holes are defined on the channel to allow cable attachment therethrough.

16. The splice plate assembly of claim 1 , wherein the splice plate, the bendable strap, and the rung are made out of aluminum.

17. A splice plate assembly for connecting at least two cable trays to effect an angle transition comprising:

a splice plate configured to connect inner side rails of the at least two cable trays to form an inside corner, the splice plate including:

an intermediate member;

first and second mounting members;

a first bendable portion having a plurality of first bendable members, the first bendable portion connected between the first mounting member and the intermediate member; and

a second bendable portion having a plurality of second bendable members, the second bendable portion connected between the second mounting member and the intermediate member;

a bendable strap configured to connect outer side rails of the at least two cable trays to form an outside corner; and

a rung adapted to be connected between the splice plate and the bendable strap.

18. The splice plate assembly of claim 17 , wherein a plurality of first and second ribs connect each of the plurality of first bendable members and the plurality of second bendable members, respectively, such that the plurality of first and second ribs provide a bending mechanism of the splice plate.

19. A method of installing a splice plate assembly, the method comprising:

preparing cable trays having a same length;

affixing a splice plate to the cable trays, the splice plate including:

an intermediate member;

first and second bendable members connected by the intermediate member at a joint angle; and

first and second mounting members connected to the first and second bendable members via first and second ribs, respectively;

connecting inner side rails of the cable trays via the first and second mounting members of the splice plate to form an inside corner;

connecting outer side rails of the cable trays via a bendable strap to form an outside corner; and

securing a rung between the splice plate and the bendable strap.
