Guardrail fixing structure (3)

The invention relates to a guardrail fixing structure (3), in particular to a combination of an impact resistant guard rail and a fixed seat, and then an auxiliary fixing seat and a fixed seat are combined, and the combined angle of the fixed seat and the auxiliary fixed seat can be adjusted, The fixed column is maintained in an upright shape, and the guardrail fixing structure of the guardrail is conveniently installed in the state of the road in a slope state.

According to the conventional guardrail, for example, Taiwan Patent No. I224643 "Guardrail fixing structure" is provided with a guard rail joint surface in the fixed seat, which is provided as a guard rail and a fixed block. The fixed block can be placed on the front side of the guard rail and then bolted. The fixing block, the guardrail and the fixing seat are fixed; and the column fixing surface can be fixed for the column column, and then the column column and the fixing seat are fixed by bolts; the guard rail can be fully fixed to the side of the road.

Or, as in Taiwan's new patent No. M353262, "Structure of guardrails" is composed of a combination of plural columns, joints and fences.

The common shortcoming of the foregoing prior art is that when the road is in a state of showing various slopes, when the column is installed on the side of the road, it still needs to maintain the erect state. At this time, the fixed seat still maintains a flat state with the column. In combination, the problem of how the guardrail will be fixed to the fixed seat will cause difficulties in construction.

To this end, the inventors of the present invention have accumulated years of experience in the design and research and manufacture of related products, and have studied and invented the case in view of the current conventional guardrail.

The object of the present invention is to provide a guard rail fixing structure which can adjust the joint angle of the fixed seat and the auxiliary fixed seat freely according to the slope of the road, and can smoothly fix the guard rail to the side of the road side and can be adjusted at any angle.

The guard rail fixing structure of the present invention mainly adopts a supporting shaft hole after the extending portion of the fixing portion to be arranged with the supporting shaft of the auxiliary fixing seat, and a plurality of holes are arranged on the wall surface after the rear extending portion, so that the bolting component is used The arc hole of the auxiliary fixing seat is combined, and the central fulcrum formed by the combination of the supporting shaft of the auxiliary fixing seat and the supporting shaft hole of the rear wall of the extending portion of the fixing seat is used as the adjusting fixing seat and The angle of the auxiliary fixing seat is matched with the slope of the road. After the adjustment is completed, the plurality of arc-shaped holes are formed on the joint surface of the auxiliary seat, and the plurality of holes are formed on the wall surface of the extending portion after the fixing seat to bolt the component. , you can install the guardrail smoothly.

The fixing base 1 is provided with a guard rail joint surface 10, and the guard rail joint surface 10 is provided with a plurality of holes 11 for combining the guard rail 3 with the fixing base 1 by the bolting element 2, and has the function of connecting adjacent guard rails to each other (Fig. 8 and 9)). The above-mentioned guard rail joint surface 10 is provided with a joint groove 12 on the upper and lower sides to be combined with the upper and lower extension faces 30 of the guard rail 3, so that the fixed seat and the guard rail can be fully combined (as shown in FIGS. 8-10).

The guard rail joint surface 10 is provided with a rear extension portion 13, and the rear extension portion 13 forms a plurality of holes 14 to form a reinforcing structure. The rear extension portion 13 is provided with a rear wall surface 15, and the rear wall surface 15 is provided with a support shaft hole 150. Preferably, the shaft hole 150 is provided at a center position, and the rear wall surface 15 is provided with a plurality of holes 151, and the holes 151 are used to engage the auxiliary fixing base 4 with the bolting elements.

The auxiliary fixing base 4, as shown in FIGS. 2 to 4, is provided with a joint surface 40 which is coupled with the rear wall portion 15 of the extending portion 13 after the fixing base 1, and the joint surface 40 is provided with a support shaft 41, and the support shaft 41 is disposed at a central position. Or the shaft hole 150 of the extending portion 13 of the fixing base 1 can be matched (as shown in FIGS. 4 and 5), so that the shaft shaft 150 of the rear wall portion 15 and the rear wall portion 15 of the extending portion 13 can be obtained. The combination (as shown in FIGS. 8-10) serves as a central fulcrum for changing the angle at which the fixing seat 1 and the auxiliary fixing base 4 are combined (see FIGS. 6 and 7).

The joint surface 40 of the auxiliary fixing base 4 is provided with a plurality of arcuate holes 42 which are distributed at the outer ring circumference of the joint surface 40, and the rear wall surface 15 of the extending portion 13 after the fixing seat 1 is provided. All of the plurality of holes 151 are bolted by the bolting member 5, but the angle of engagement between the aforementioned fixed seat 1 and the aforementioned auxiliary fixed seat 4 must be adjusted before bolting. The fulcrum can be used to adjust the joint angle of the fixed seat and the auxiliary fixed seat to fit the road state to install the guardrail.

A joint portion 43 is provided on the rear side of the joint surface of the auxiliary fixing base 4, and the joint portion 43 is used for the fixing post 6 and is therefore provided with a recessed portion 430. The recessed portion 430 is defined as a cylindrical or square pillar. Formed in a shape or other shape, and the extending surface 431 on both sides of the joint portion 43 is provided with a hole 432. After the joint portion 43 and the side cover 44 jointly cover the fixing post 6, the auxiliary fixing seat 4 can be The fixing column 6 is combined. The invention can be combined with the actual construction requirements to form a single or double guardrail 3 structure.

In summary, the present invention can utilize the change and adjustment of the joint angle between the fixed seat 1 and the auxiliary fixed seat 4, so that the guardrail can be constructed in accordance with the difference of the slope of the road, and the joint between the guardrail and the fixed seat can be maintained well. The combination of the state, and the installation of the guardrail at various angles, to enhance the practical value of the impact barrier, is the composition of the case.
