The present invention relates to a bridge inspection path integrally formed in the head of the pier, more specifically to the work scaffold that can move the worker along the pier or the circumference for the repair, reinforcement or defect inspection of the bridge, work to prevent accidents A bridge inspection path including access facilities such as railings and circular ladders installed along the circumference of the scaffold.

In order to periodically check and maintain the new bridge or the existing bridge, the bridge typically installs the bridge inspection path 101 along the pier head 103 'or the circumferential head as shown in FIG.

The bridge inspection road 101 is formed around the pier head 103 'formed on the top of the pier 103, in particular, the floor plate to help the passage of the access facility 113 and the worker so that it can be checked at all times without traffic restrictions. And a handrail 111 extending lengthwise from the bottom plate 112 vertically,

Typically, the bridge inspection is installed by assembling and attaching a channel, a section steel or a bottom plate of steel or aluminum material along the pier head 103 'concrete structure.

That is, the bridge inspection path 101 provided for the safety of the inspector to inspect the bridge along the pier head (103 ') or the worker to repair it is typically anchor bolt (around the tip of the pier head 103') After anchoring the H-beams 114 vertically via an Anchor Bolt (not shown), the other H-beams 115 are inclined at an appropriate angle upwards in the vertically positioned H-beams 114. Brackets are installed by tilting, and the bridge inspection path is installed by fixing the bottom plate 112, which is generally made of aluminum, over the bracket composed of both H-beams 114 and 115. In addition, handrail 111 is also generally fixed to the position through a variety of fastening means such as brackets and bolts or welding perpendicular to the bottom plate (112).

Furthermore, the bridge inspection path 101 has a ladder-shaped access facility extending from the side of the slab 104 to the bottom plate 112 so that the inspector can safely access the bottom plate when inspecting the bridge 102. 113) will be installed.

This allows the inspector or worker to move along the work path provided by the bottom plate 112 fixed around the pier head 103 'and check the state of the main components of the bridge.

In this way, the conventional method of installing the bridge inspection path follows the installation method after completing all the shifts, bridges, and slabs, so that a separate working means for installing the bridge inspection path is required. However, as a means of work, a separate scaffold is used, and a work bench installed in a vehicle is installed around a shift or a pier to install a bridge inspection path, which is complicated in both types of work, increases installation costs, and works at heights. There was a safety problem. Furthermore, in order to easily install the bracket, the bottom plate, and the railing constituting the bridge inspection path, it is common to use an aluminum product in consideration of light weight, durability, and external appearance for ease of transportation and installation work. In other words, if it is made of steel, corrosion is caused by long-term oxidation of air pollutants and air, and the melt flows along the bridge, causing aesthetic sensation, and in addition to the burden of maintaining the bridge periodically. This is because additional costs for maintenance of the inspection furnace 101 must be secured.

In addition, once the failure occurs in the bridge inspection road 101 itself must be reinstalled. In general, since the upper slab 114 supported by the pier 103 is held high from the ground, high work is essential for the maintenance and repair of the facility. As a result, there was a problem of safety accidents and additional costs required for the installation of temporary facilities, for example, work scaffolding, due to high-working.

In addition, the installation and dismantling of the bracket and the floor board and the work for arranging the bottom plate 112 around the piers are not able to avoid some damage to the already formed structure, and thus there is a problem in that structural problems and deterioration in construction are inevitable. .

Most of these problems are due to the following method of installing the bridge inspection road after the completion of the bridge, the present invention has developed a bridge inspection road installation method to solve these problems fundamentally.

An object of the present invention is to provide a bridge inspection path for installing the bridge inspection path on the bridge more economically and easily.

Another object of the present invention is to provide a bridge inspection path that is easy to reinstall work and maintenance.

In order to achieve the technical problem, the bridge inspection road according to the present invention is characterized in that the bridge inspection path may be installed together when the bridge or the bridge is formed, so that the additional installation of the bridge inspection path may be omitted later. .

In addition, when the bottom plate constituting the pier inspection path is to be formed integrally together with concrete when placing alternating or pier concrete, the workability can be greatly improved, and in the case of handrails, it can be installed simply by inserting it into the concrete floor plate. The technical feature is that bridge inspection can significantly reduce installation air.

In order to explain the present invention more clearly and easily described in detail by the accompanying drawings the best embodiment of the present invention, the embodiment according to the present invention can be modified in various other forms, the scope of the present invention Is not limited to the embodiment described below.

1 is a front view of the bridge inspection path according to the present invention installed in the head of the bridge in a bridge direction.

As shown, the bridge 2 can be broadly divided into a superstructure and a substructure, which refers to a structure seated on an alternating or pier 3, and generally refers to girders and slabs ( Slab, 4) and so on. In addition, the upper slab 4 and the lower structure which serves to safely transmit the load applied to the superstructure to the ground is provided with a bridge device 5 between the alternating and the piers (3).

The upper slab 4 of the bridge 2 is seated above the bridge 3 and the alternating substructure, in which the upper part of the bridge 3 (here A bridge inspection path 1 is provided to provide a worker's passage around the head. Due to the bridge inspection path (1) is secured a work space that can confirm the safety of the bridge without restricting the traffic of vehicles or people passing over the bridge (2).

Unlike the prior art, the bridge inspection furnace 1 according to the present invention is characterized in that it is integrally formed with the head of the bridge 3 at the time of construction of the bridge 3.

The bridge inspection path 1 is composed of a bottom plate 12 that secures a passage of a pedestrian and a handrail 11 that extends vertically upward from the bottom plate 12. In addition, an access facility 13 is provided to move the inspector from the upper slab 4 to the bottom plate 12.

FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1 and is a plan view of the structure of the bridge 2 viewed downward while the upper slab 4 is removed.

Four scaffolding devices 5 are shown which support the upper slab 2 (see FIG. 1) onto the pier head 3 'which is rectangular in shape and are integrally radially circumferentially around the pier head 3'. It consists of a bridge inspection path 1 including a bottom plate 12 extending outward and formed of reinforced concrete. In addition, as described in FIG. 1, a railing 11 for worker safety is installed around the periphery of the bridge inspection path 1.

3 is an installation state diagram of the bridge inspection path (1) according to the present invention. Bridge inspection path 1 formed integrally extending around the pier head 3 'is composed of a bottom plate 12 made of concrete and a handrail 11 made of steel, preferably aluminum having corrosion resistance. .

Figure 4 schematically shows the installation procedure of the bridge inspection path according to the present invention.

Although not shown in the drawing, in the main reinforcement and secondary reinforcing bars in the interior of the pier head (3 '), additional reinforcement is installed almost parallel to the upper slab (4) and the formwork is installed, the concrete for the bottom plate pour concrete And pour together simultaneously. After the concrete undergoes curing, railings 11 are placed along the outer edge of the bottom plate 12 and fixed. Preferably, the handrail 11 is inserted into the insertion hole 16 formed spaced apart at predetermined intervals along the outer end of the bottom plate 12 and the mortar is filled in the insertion hole to ensure that the handrail is fixed to the bottom plate. You can do that.

Specifically, the pier head (3 ') is provided with a support (not shown) for forming the pier head, using the support for installing the bottom plate 12 of the present invention, but the bottom plate forming operation It can be installed to extend more outward than the intelligence. As a result, since the conventional support for forming the pier head is used, there is no need to install a separate support for the support.

Next, after adding and installing additional reinforcing bars inside the concrete for the bottom plate, formwork is installed, and additionally, holes for block-out are formed to insert a railing to be positioned at the outer end by bridge inspection. In order to install a pipe and the like having a predetermined diameter and cross-sectional shape so as to form an insertion hole 16 to facilitate the entry of handrails.

Next, a first pouring step (A) is performed in which the concrete is integrally poured together with the pier head to the height (H) of the bottom plate, and then the pier head concrete is completely cured after the first pouring. The second casting step (B) is to be poured.

After disassembly of the temporary facility (for example, formwork and scaffolding) after placing, the railing is inserted into the insertion hole 16 formed of a pipe embedded in the outside of the bridge inspection table. The reason for separating and placing the piers 3 in the steps A and B is that the height H of the bottom surface 12 of the inspection road when the piers 3 are continuously placed to the upper end of the piers 3 'when placing the piers 3 is placed. This is to prevent the concrete from rising higher than the poured concrete. At this time, the old and broken handrail 11 can be dismantled from the insertion hole and the new handrail 11 can be inserted into the insertion hole 16 for maintenance of the handrail 11, which may be generated later. Is advantageous.

As described above, according to the present invention, when the bridge head is formed, the bridge inspection path formed integrally with the bridge by concrete does not need to be installed separately later, so the installation work is very excellent as bridge inspection, and the maintenance is easy as well. In addition, the construction cost can be saved much more than installing the bridge inspection path separately, and it can be installed together with the pier head to reduce the labor, and provide the beautifulness of the structure by integral construction with the pier head. Therefore, maintenance costs can be reduced.
