The present invention relates to a mobile multipurpose temporary bridge comprising: a support block (10) having a cabinet-shaped body, and both sides of which have respective support surfaces (12) and the lower surface of which has a shaft hole (14); and a locking shaft (20) secured to the shaft hole (14) of the support block (10) to connect and lock the support blocks (10) together such that the support blocks (10) are rotatable. Each of the support surfaces (12) is tapered as it goes toward an end thereof. A locking portion (13) has a recess and a protrusion which are symmetrically formed at both sides thereof. The shaft hole (14) is formed through the protrusion of the locking portion (13). The support blocks (10) are interconnected, and locking shafts (20) are secured into the respective shaft holes (14). Then, ends of the locking shafts (20) are fixed by means of respective anti-escape members (21) such that the support blocks (10) are folded or unfolded about the respective locking shafts (20). In addition, the support surfaces (12) formed at both sides of each of the support blocks (10) have protrusions (15) and grooves (16) arranged alternately with one another such that the support blocks (10) can be fitted together, thus increasing the strength of the product. |
