Description

Pier Inspection Platform {Inspection plate for a pier}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a bridge inspection platform for inspecting a bridge device, a bridge portion, or an upper slab of a bridge, etc., installed around the lower slab of a bridge in a bridge. It is related to the pier inspection platform that is easy to install.

In general, bridges and bridges are installed in the upper part of the bridge, and the upper slab, which is placed between each of the upper bridges, is provided with driveways and sidewalks, and steel box girders are interposed on the lower stems. For management purposes, the slab on the stem is provided with a check table including a passage for the check and a handrail to prevent the checker from falling.

Such a conventional check table is usually L-shaped steel is fixed at a certain interval around the piers by anchor bolts, and supports it as a brace, the outer periphery of the end of the c-shaped steel to lay all the coupling site is fixed by welding method.

In addition, handrails are also welded and fixed at regular intervals, so the air in installing the pier inspection stand becomes longer, and maintenance inspection due to partial breakage and corrosion of them, and all the partial coupling elements are welded, thus cutting and rewelding one by one. There were a lot of difficulties.

For these reasons, a technique has been devised by the Applicant to quickly install a pier inspection stand prefabricated using aluminum diecasting material.

The present invention was devised to solve the above-mentioned problems, and an object thereof is to provide an pier check stand that is easy to assemble and to easily repair even if partial breakage occurs.

In order to achieve the above object, the present invention provides a bracket attached to a piers, a square pipe assembled to and fixed to the bracket, a channel bar assembled at the end of the square pipe, a post assembled to the channel bar, and a scaffold between the channel bars. It is divided into an angle, a support plate, etc. to assemble, characterized in that the assembly is configured as if the assembly toy.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A bracket having an assembly groove 11 on the front surface, a protrusion jaw 12 on the lower side, and a hole (H) fixed to the piers on the lower surface thereof and a fixing hole (h) on both side walls of the assembly groove 11. 10,

A square pipe 20 having one end inserted into the assembling groove 11 of the bracket 10 and having at least one structural partition wall 21 at an inner cross section;

The lower part of the rectangular frame 31 has an angle locking cover 32 which covers the end of the rectangular pipe 20 so as to be able to hang, and the upper part has an angled wall 33A at the front and a vertical wall 33B at the rear. A channel bar 30 having a post coupling groove 33 to be formed, and an insertion groove 34 formed as protrusion pieces 34A and 34B extending from the upper and lower frames of the square frame 31 on one side thereof;

An angle 40 having an insertion groove 44 corresponding to the insertion groove 34;

Footrest extending in the longitudinal direction of the piers including a support piece 51 is inserted into the grooves 44, 34 of the angle 40 and the channel bar 30 and supported on the upper surface of the square pipe 20 therebetween. 50,

A pipe clamp 70 having a hole 71 for penetrating the handrail pipe 60 and coupled to an upper portion thereof;

The lower plate 82 is inserted into and fixed to the insertion groove 33 of the channel bar 30, and at least one pair of side holes 81 has a post 80.

In the drawings, reference numeral B denotes a fastening member, and h denotes a hole or a fastening seat for fixing.

The operation of the present invention, which is assembled as described above, will be described according to the assembly procedure.

First of all, the anchor bolt (not shown) for installing the pier inspection stand is formed at a predetermined position around the top of the pier. Of course, the means for making this better has also been filed by the present applicant, but is a matter that is not discussed in the present invention.

Anyway, fit the hole (H) formed on the rear surface of the bracket 10 of the present invention to the anchor bolt installed and fastened and fixed with a nut (not shown).

Then, the front end of the square pipe 20 is inserted into the assembling groove 11 of the bracket 10, and then fastened and fixed to the fastening member B from the holes h on both sides where the assembling groove 11 is formed.

At this time, the square pipe 20 may have a support force having a sufficient support seat plus the length of the portion inserted into the assembly groove 11, and the extended length of the protruding jaw 12.

In addition, the structural partition wall 22 of the square pipe 20 will provide sufficient structural strength to withstand the weight of the supporter 51 and the footrest 50 mounted thereon as well as the load of the person walking thereon.

And the one side edge of the footrest is inserted into the insertion groove 44 of the angle 40, the other edge is in the state of being inserted into the insertion groove 34 of the channel bar 30, the angle locking cover 32 of the channel bar 30 To cover the end of the square pipe 20 to be able to hang. Therefore, this has the effect of covering the end of the square pipe 20.

At this time, the vertical wall 33B of the channel bar 30 will have a barritic function to prevent any small objects from rolling down from the check table.

On the other hand, by fixing the fastening member (B) from the top of the insertion grooves (34, 44) to effectively secure the footrest (50).

Angle 40 and the channel bar 30 in the above will be used as the length of the cut appropriately according to the size of the piers.

And the post 80 is inserted into the post groove 33 at a predetermined interval of the channel bar 30, which is coupled, which is the bottom plate 82 is against the bottom of the post groove 33 and the fastening member (B) Fix and fix. Thereafter, the handrail pipe 60 is completed by using the holes 71 of the pipe clamp 70 fitted to the upper end of the post 80 and the side holes 81 formed in the post 80 itself.

The present invention, which is assembled and assembled as described above, is assembled and fixed to a total of nine parts to form a finished product, and has a shorter air with an installation time that is considerably faster than that for forming a steel pier inspection stand by conventional welding, and in particular, pier inspection As the scope of work by maintaining the base itself becomes narrow, there is an advantage that, for example, simply dismantled and then assembled and repaired only a local part requiring repair and replacement.

The present invention constructed and operated as described above is easy to assemble, and even if partial breakage is provided, it is easy to repair and provides a pier inspection stand that can concentrate only on the original task for pier inspection, maintenance and maintenance effect Provides novelty and inventiveness.
