An assembly-type barricade comprising a base stand and an upstanding wall both of which are nearly rectangular parallelpipedal. Protruding means is provided in one of the base stand and the upright wall, and receiving means is provided in the other. By positioning the protruding means in the receiving means, the upright wall is detachably mounted on the base stand.

Claims

1. An assembly-type barricade comprising a base stand which is set as desired, and an upright wall which is mounted detachably on the base stand, wherein

a plurality of assembling protrusions spaced from each other in a predetermined direction are provided in the bottom surface of the upright wall,

a plurality of assembling through holes spaced from each other in a predetermined direction are formed in the base stand in correspondence to the plural assembling protrusions

linking lateral holes are formed respectively in the plural assembling protrusions so as to extend therethrough, linking lateral holes are formed in the upper end portion of the upright wall so as to extend therethrough, and linking lateral holes are formed in the plural assembling through holes of the base stand so as to extend therethrough,

linking vertical holes extending vertically through the upright wall and the plural protrusions are formed in the upright wall in correspondence to the plural protrusions,

said plural protrusions of the upright wall being detachably insertable through the plural through holes of the base stand to a position where the linking lateral holes formed in the plural assembling protrusions and the linking lateral holes formed in the base stand are aligned laterally, and at the same time the plural linking vertical holes communicate with the plural through holes of the base stand,

said plural protrusions of the upright wall being detachably insertable through the plural linking vertical holes of another said upright wall to a position where the linking lateral holes formed in the plural protrusions of the upright wall and the linking lateral holes formed in said another upright wall are aligned laterally, and at the same time the plural linking vertical holes of the upright wall and the plural linking vertical holes of said another upright wall communicate with each other vertically.

2. The barricade of claim 1 wherein the plural assembling through holes are provided in plural pairs in spaced-apart relationship in a direction substantially perpendicular to said predetermined direction.
