Description

Bridge check platform in the direction of bridges {BRIDGE INSPECTION OF LENGTH COURSE}

The present invention relates to a bridge inspection platform in the axial direction that is installed on the lower side of the bridge, and more particularly to a bridge inspection platform in the axial direction that can inspect the main beam and cross beam precisely and in detail.

In general, a bridge is composed of a top plate, which is a plate structure, a girder supporting the top plate, and a pier supporting the girder. Checking is essential.

In other words, the bridge inspection service aims to ensure the safety and smooth traffic flow of users by identifying the phenomenon of bridges, detecting abnormalities and damages early, and taking appropriate measures. It is necessary.

Referring to Figure 1, the longitudinal safety inspection passage of the conventional bridge (Domestic Utility Model Application No. 20-1999-0015892) is provided with a plurality of steel boxes long in the longitudinal direction to support the bridge in the lower part of the bridge, A plurality of cross beams 10 are provided at regular intervals between the steel boxes in the transverse direction. In addition, the cross beam 30 is provided with a safety inspection passage 20 through which an inspector or the like may pass to inspect the lower side of the bridge in the longitudinal direction of the bridge. And a fixing stand 25 fixed to the longitudinal safety check passage 20 and vertically fixed in the direction of the cross beam 10, and fixed up and down at a predetermined distance to an upper end of the fixing stand so that the cross beam 10 of the It consists of two pairs of clamps 30 fitted to both sides.

The longitudinal safety inspection passage of such a conventional bridge has the following problems.

First, the connection of the guard rail and the railing column is fixed by welding or the like, and the fixing stand 25 is fixed to the crossbeam 10 by using a plurality of bolts by using the clamp 30 so that the safety check passage is installed. It takes a lot of time to work. In particular, there is a problem that can cause a serious problem in safety due to cracks generated in the weld portion due to frequent temperature changes.

Second, in general, the bridge is designed to be arched for safety, but since the longitudinal safety check passage is always installed in a horizontal state, the pedestal 23 and the footrest to form a curve corresponding to the bridge Therefore, when the pedestal and the scaffold are installed to be curved in correspondence with the bridge, the pedestal and the scaffold are not in close contact, and one side is lifted, causing a problem of safety in that the load is directed to only one side. (See Figure 1)

The present invention is to solve such a problem, to provide a bridge check platform in the axial direction easy to install and excellent in safety.

According to a feature of the present invention for achieving the above object, the bridge check platform in the axial direction has a pair of hangers installed in the vertical direction from the horizontal bracket installed in the transverse direction below the bridge, this pair of hangers A pedestal having an upper flange on which the passage footrest is mounted is fixedly installed. The pedestal is rotatably installed on the pair of hangers so that it can be fixed inclined. The pedestal is fixed to both ends of the handrail. The pedestal is a handrail fastening portion is fixed to the rail handrail is fitted on both sides; The pair of hangers are fitted at both ends to have a support fastening part fixedly installed.

For example, embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited by the embodiments described below. This embodiment is provided to more completely describe the present invention to those skilled in the art. Accordingly, the shape of the elements in the drawings and the like are exaggerated to emphasize a clearer description.

Hereinafter, an embodiment of the present invention will be described in more detail with reference to FIGS. 2 to 5. In the drawings, the same reference numerals are given to components that perform the same function.

2 is an exploded perspective view of the bridge inspection platform according to the first embodiment of the present invention. 3 is a front view of the present invention shown in FIG. 4 and 5 is a view showing a bridge inspection stand construction state according to the embodiment of the present invention from the front and side, respectively.

2 to 5, the present invention is a bridge check platform that is a structure that is constructed to check the lower side of the bridge in the bridge direction (longitudinal direction) of the bridge, looking at its configuration, horizontal bracket 110, It is composed of a pair of hangers 120, pedestal 130, handrail support 140, handrail 150, and passage scaffold 160.

Both ends of the horizontal bracket 110 are fixed to the girder under the bridge, and are disposed in the transverse direction of the bridge. The horizontal bracket 110 is installed side by side at regular intervals as shown in FIG. The horizontal bracket 110 has a structural feature that the cross section is made of a rod shape.

The pair of hangers 120 is fixed to the horizontal bracket 110 in a vertical direction. Here, the pair of hangers 120 is not fixed to the horizontal bracket 110 using a separate clamp. As shown in the figure, the hanger 120 is fitted to the horizontal bracket 110 in the first hole 122 formed at one end to be suspended to the horizontal bracket (110). And fix it with one bolt to prevent right and left movement. As such, the present invention has a structural feature capable of fixing the hanger 120 to the horizontal bracket 110 very simply and easily and stably.

On the other hand, the pair of hangers 120 is formed at the other end of the second hole 124 for fixing to the pedestal 130.

The pedestal 130 has an upper flange 132 on which the passage scaffold 160 made of a wire mesh or the like is placed so that the inspector can pass safely, and the second hole 124 of the hanger 120 at both ends thereof. The hanger fixing part 134 fitted in the protrusion protrudes. The pedestal 130 is supported by being fixed by bolts while the hanger fixing part 134 is fitted into the second hole 124 of the hanger 120.

Here, the important point is that since the second hole 124 and the hanger fixing portion 134 of the hanger 120 is made of a circular shape, when the pedestal 130 is fixed to the pair of hangers 120 It has a structural feature that can be fixed in a rotated state.

As such, the present invention can be fixed to the hanger 120 in a state in which the inclination of the pedestal 130 fixed to the hanger 120 is inclined, as shown in FIG. There is an advantage that can be installed in a curved state to fit the circumference of the bridge. By constructing the curvature in accordance with the circumference of the bridge, there is an advantage that the load transmission to the pedestal 130 is uniform, and the overall safety of the bridge check platform 100 is improved.

The handrail fixing part 136 to which the handrail strut 140 is fitted is formed on both upper surfaces of the upper flange 132 of the pedestal 130. The handrail prop 140 is fixed by bolts after being fitted to the handrail fixing part 136. The handrail strut 140 has handrail connecting portions 142 to which the handrail 150 is fitted at both sides. As shown in the figure, the handrail connecting portion of the handrail support 140 has a cross shape and a tee shape.

For example, the hanger 120 and the pedestal 130 is integrally formed by extrusion molding of aluminum, the railing 150 is preferably made of stainless steel.

Using the bridge check platform 100 in the axial direction of the present invention as described above, the construction can be carried out quickly, simply and beautifully, and in particular, the bridge check platform can be curvature to fit the circumference of the bridge, passage scaffolding The load transmission from the to the pedestal is uniform, and thus, the safety of the bridge inspection platform is improved.

In the above, the configuration and operation of the bridge check platform in the axial direction according to the present invention is shown in accordance with the above description and drawings, but this is only an example and various changes and modifications within the scope without departing from the technical spirit of the present invention Of course this is possible.

The present invention having the above-described configuration and function is easy to install and excellent in safety. In particular, it is possible to construct the bridge check platform to be curvature to match the circumference of the bridge.
