BRIDGE PLANK APPLICABLE TO CONSTRUCTION SITES
BRIDGE PLANK APPLICABLE TO CONSTRUCTION SITES A bridge plank applicable to construction sites includes a main board, a left wall and a right wall which are respectively disposed at two sides of the bottom of the main board. The left and right walls are integrally molded with the main board. Front and back ends of the main board are each provided with an end cap. The left and right walls are identical in structure and each includes an outer wall. Bottoms of the outer walls are bent towards the inside of the main board to form footings that are parallel to the main board. Ends of the lower bent footings are then bent upwards to form inner walls. Top edges of the inner walls are in direct contact with the bottom of the main board. Compared with the prior art, this bridge plank is strengthened in rigidity and completely eradicates potential safety hazards. 1>7 i/f k~.d ~- 4'7 4 4 ~ ' '4 4 4 * 4 * (~\* '4 '4 4 KS 4.. 1* * N: 4 (4 \ '4 '~> '\~ I~ * :* i:~ ~ '4> - '7 4 '4 ~±1 '0 ''7 '74 4 '7 4, 4 '4 'S V ~ is,> ii /4: U C
