The present invention relates to an integrated traffic sign in which various traffic safety signs, road signs, and auxiliary signs such as pedestrian road signs or bicycle road signs are prefabricated together, and more specifically, are fixed vertically on the ground in a column shape. The base concrete member embedded in the lower part is fixedly attached to the lower part, and the vertical supporter is perforated with the support hole through which the support hole is inclined diagonally in the horizontal direction, and the state is vertically inserted into the support through hole and obliquely inclined in the horizontal direction. A fixed support which is integrally welded to the prop is provided, and the fixing support has a subsidiary sign mounting tool assembled downward at one end thereof, such as a pedestrian road sign or a bicycle road sign on the front and rear surfaces of the sub sign mounting device, respectively. As the auxiliary sign is adjusted up and down, The other end of the fixed support is provided with a fixed support for supporting the sign mounting in a state in which one end of the sign mounting unit is connected integrally, and a sign mounting stand that is extended in the horizontal direction at the other end of the fixed support in a long straight line. The sign mounting stand has a plurality of upper fastening holes and lower fastening holes at a predetermined interval in the transverse direction, respectively, in the upper surface portion and the lower surface portion. Prefabricated integrated traffic signs, characterized in that the assembly is installed in a screwed state and the plurality of upper sign mounting holes and lower sign mounting holes are composed of a sign installation unit is configured to be installed while adjusting the road signs and various traffic safety signs up and down height It is about.

In general, traffic signs are installed on the side of the road, and traffic safety signs such as various regulatory signs, caution signs, and indication signs are installed, and road signs indicating the name of the road are used to provide traffic conditions and traffic guidance to drivers and pedestrians in traffic. As shown in FIG. 5, the conventional traffic sign 28 'is provided with a vertical column 5' installed vertically along a road in a long column shape as shown in FIG. 5, and the vertical column 5 '. In the upper part of), a long rod-shaped sign mounting stand 19 'which is installed in the transverse direction is fixedly attached, and the sign mounting stand 19' is fixed in a state in which it is positioned across the top of the road. A plurality of traffic safety signs 2 ', which are assembled by 29', are provided, and a pair of vertical supports are provided on the upper surface of the sign installation stand 19 '. (30 ') is such that the front is welded various road sign 3' in (a said vertical support 30) from the welded attachment vertically upward state.

However, in the conventional traffic sign 28 'as described above, a plurality of traffic safety signs 2' installed on the sign mounting stand 19 'are fastened by fastening clamps 29', respectively. When an external force is applied, the traffic safety sign 2 'is rotated or skewed, making it difficult to identify a driver or a pedestrian. The traffic safety sign 2' assembled to the sign mounting stand 19 'is illustrated in FIG. As it is always located in accordance with the sign mounting 19 (19 '), when installing a plurality of traffic safety signs (2') of the sign mounting 19 (19 ') is installed on the top of the sign mounting (19'). The road sign 3 'or various traffic lights (not shown) are overlapped or covered by the traffic sign 2', so that a driver or a pedestrian cannot be correctly identified. (3 ') There was a problem that you can not install multiple at once.

In addition, auxiliary signs (not shown), such as pedestrian road signs and bicycle road signs indicating pedestrians or bicycle roads, cannot be installed together with the traffic signs 28 'so that separate traffic signs (28 There was a problem to install an auxiliary sign such as a pedestrian road sign or a bicycle road sign.

The present invention has been made to solve these problems, so that various signs are assembled by screwing without using a separate clamping clamp so that the signs are not crooked or turned by external force, and a plurality of traffic safety signs on the sign installation stand and While the road signs are installed together, the height can be adjusted up and down so that various signs do not overlap or obstruct each other so that easy identification can be achieved. In addition, it can be installed with auxiliary signs such as pedestrian road signs and bicycle road signs. Its purpose is to make it easy to distinguish roads, sidewalks and bicycle paths through a single traffic sign.

In order to achieve this purpose, it is installed vertically fixed on the ground in the form of a column and the vertical support is perforated through the support hole through the inclined obliquely in the horizontal direction, and vertically inserted into the support through the inclined obliquely in the transverse direction in the longitudinal direction. The support is provided with a fixed support integrally welded to the support stand, and the fixing support is assembled at the end of the sub-support plate mounting downwards, and the sub-plates are installed on the front and rear surfaces of the sub-plate mounting holes, respectively. The other end of the fixed support is provided with a fixed support for supporting the sign mounting in a state in which one end of the sign mounting unit is connected integrally, and a sign mounting stand that is extended in the horizontal direction at the other end of the fixed support in a long straight line.
