Trench wall support

1. A trench wall support, comprising;

a board for contacting a support surface to transmit a supporting load thereto;

a load bearing surface for receiving the supporting load from a prop, the prop comprising a telescopic tube extending between opposing transversely extending feet;

a bracket coupled to the board, the bracket arranged to support an end of the prop at a load bearing position on the load bearing surface;

wherein the bracket comprises a guide for guiding the prop to the load bearing position;

wherein the bracket comprises an overhang to accommodate one of the feet of the prop when guiding the tube to the load bearing position;

wherein the guide is formed as a slot formed from an edge of the overhang and dimensioned so as to engage said telescopic tube of the prop, with an end of said telescopic tube adjacent one of the feet of the prop positioned within the slot; wherein the bracket comprises a plurality of tracks, each track arranged to direct the prop to an alternative load bearing position; and

wherein the tracks have the same configuration as the slot; and wherein the edge of the overhang is continuous and also defines an access port for allowing said one of the feet of the prop to pass for contacting the load bearing surface, wherein the access port defines a central hub having the slot and each track extending therefrom.

2. The trench wall support of claim 1 wherein the guide is oriented to guide the tube downwards, in-use, to the load bearing position.

3. The trench wall support of claim 1 , wherein the slot is dimensioned for clearance fit with the tube.

4. The trench wall support of claim 1 , wherein the slot is substantially U-shaped, wherein the bend of the U-shaped slot forms a seat to support the tube of the prop at the load bearing position.

5. The trench wall support of claim 1 , wherein the tracks are oriented in a direction including one or more of upwards, left, and right, in-use.

6. The trench wall support of claim 1 , wherein the tracks are U-shaped slots, wherein the bend of each U-shaped slot of the tracks forms a unique stop for limiting the respective alternative load bearing position to within predetermined limits on the load bearing surface.

7. The trench wall support of claim 1 , wherein the edge is dimensioned to permit passage of one of the feet in a first rotational position of the prop and dimensioned to prevent passage of said one of the feet in a second rotational position of the prop.

8. The trench wall support of claim 1 , further comprising a base plate mounted to the board, the base plate providing the load bearing surface.

9. The trench wall support of claim 1 , made from a plastics material.

10. The trench wall support of claim 9 , wherein the plastics material is glass reinforced plastic (GRP).

11. The trench wall support of claim 9 being made by injection molding so as to form a substantially monolithic structure.

12. A trench support assembly comprising the trench wall support of claim 1 , and the prop.

13. A method of supporting a prop comprising;

providing the trench support assembly of claim 12 ;

erecting the support against a support surface;

guiding the prop to a load bearing position against the load bearing surface, using the guide;

supporting an end of the prop at the load bearing position using the bracket; and

extending the prop to exert a load to the load bearing surface.
