Description

{Four-way binding bracket of single binding means for hanging bridge inspection facilities}

The present invention is not limited to the shape of the pier as a single binding means, and by simply and conveniently fitting and binding the components of the inspection facility to the top and bottom, front and rear, left and right, regardless of the position and direction, it is hung on the pier without bolting by a separate anchor means. It relates to a four-way binding bracket of a single binding means for a hanging bridge inspection facility that can be constructed and installed by transplantation, and more specifically, a pier in which the components of the inspection facility, which is a bridge inspection facility, are installed and bound to the pier in a hanging manner. It is a common binding means that unifies all the components of the inspection facility that are inserted and tied to the sidewall by anchor method of pre-buried or post-buried without a separate complex anchoring means. It relates to a four-way bundling bracket of a single binding means for a bridge inspection facility that allows for quick fitting and fastening and installation and construction.

In general, inspection facilities installed on the side walls of piers of bridges are designed to improve bridge management efficiency, such as checking and inspecting functional conditions, aging and defects in each part of the bridge structure, and improving the bridge management efficiency. installed on the side wall. This is a bridge safety inspection, maintenance, facility repair, reinforcement work facility, and fitting work facility, which is useful for the maintenance and management of bridge construction. to be.

And in the case of the bridge inspection facility, first, in the case of an anchor-type construction structure, the vertical support is basically coupled and fixed to the side wall of the pier through the anchor means (normally anchor bolts are applied) by pre-burial or post-burial, and the support is interposed. As the horizontal pedestal is coupled and fixed to the lower part of the pier, the vertical balustrade is coupled and fixed to the outer end of the pedestal, and the inspection foot, which is the floor passage of the inspection facility where the operator works while moving, is usually bolted on the pedestal. In addition, it is common to form an inspection facility for the side wall of a pier by installing a horizontal balustrade rod at regular intervals on the balustrade to prevent an operator's fall accident.

In addition, the bridge inspection facility differs from the cumbersome and difficult anchor-type construction structure in which the vertical support on the side wall of the pier is first bound and fixed by the anchor means installed in a separate pre-buried or post-buried, vertical support and handrail applied in the anchor type. Inspection facilities on piers by additionally configuring horizontal hangers and reinforcing bars in the upper part of the pier in addition to the horizontal pedestal and installing and applying different types of components that form these inspection facilities to the relevant binding site. It can also be configured to be installed in a hanging manner.

On the other hand, the anchorage facility of the bridge embeds the anchor means in the side wall of the pier, bolts the basically vertical support through the anchor means, and integrates the inspection facility with other components by bolting normally. In this case, since the support, which is a steel structure, is usually fixed to the wall of the pier as an anchor bolt, damage to the pier is easy to occur. Not only cannot the fixed state be maintained, but in some cases, there is even a risk of falling due to structural instability such as shaking of the inspection facility.

In other words, although there are differences depending on the size of the existing anchor-type inspection facility, dozens of anchor bolts are first inserted into the pier and the inspection facility is formed around the support together with the support of the side wall of the pier. It is usually installed by combining elements and bolts. As a long time passes after installation of the inspection facility, damage and corrosion of the anchor bolts connected to the piers, which are concrete structures, occur, eventually lowering the load-bearing capacity of the piers, reducing the safety factor as well as aesthetically. bad results may occur.

On the other hand, the existing hanging inspection facility, which was improved to solve the various inconveniences and problems of the anchor-type inspection facility due to the coupling method of the anchor bolt described above, can prevent corrosion or damage to the cement of the pier by the use of the anchor bolt. , the structural safety of the inspection facility is inevitably weak as it has no choice but to install the supports avoiding the shoe on the upper side of the pier. There are many problems that occur with

Also, in the case of a bridge in which the upper part of the pier to which the shoe is attached has a step as a whole, the installation itself is structurally difficult due to the configuration of the hanging type inspection facility so far, and even if it is installed with difficulty, the amount of work required will increase more than necessary. In addition, structurally, it is difficult to maintain a stable support state, so there is a problem in durability.

In particular, the construction method of both the anchor-type inspection facility as well as the previously introduced hanging type inspection facility is very complicated, and the binding means for the components of each length of the inspection facility are also used for binding parts and bindings. Since a number of binding means of various structures and shapes are required depending on the location, the number of parts of the total components is larger than necessary and cannot be interchanged or standardized. As a result, additional parts for improving the bonding strength between the components As the number of types of parts for insertion and coupling increases, the construction work is complicated and difficult, and there are various inconveniences such as a decrease in overall workability and waste of construction cost, as well as the inability to achieve standardization and compatibility at all.

An inner central separation portion of a certain length (height) in the form of a ruler (square) is formed to protrude, and the inner central separation portion has an open end so that the corresponding structure of the inspection facility can be inserted and bound in only one horizontal or vertical direction,
The outer binding protrusions are respectively formed to protrude at the same height as the protrusion height of the inner central septum in the closed lateral direction on the four side around the inner central septum, and the outer binding protrusions limit the horizontal or vertical direction of the corresponding structure of the inspection facility. The cross-section is protruded in the shape of a 'C' in both horizontal and vertical directions so that it can be inserted and bound without being inserted.
In order for the corresponding structure of the inspection facility to be inserted and bolted to the end of a certain length in the vertical or horizontal direction, the main body-damping flat part, which is a closed entire surface of one side of the four-way binding bracket, has a '+' shape in cross section as a whole. and the outer binding protrusion of the oblique part with both vertical and horizontal ends open together with the main body closing flat part of the central part with the opposite end open is generally configured as a right-angled '#' shape in cross section. A four-way binding bracket of a single binding means for a hanging bridge inspection facility. The method according to claim 1,
The four-way binding bracket is installed and configured so that all of the structures of the inspection facility 20 can be inserted and bound as a single binding means without being limited in vertical and horizontal directions,
On the upper side of the side wall of the pier, the four-way binding bracket is installed in the horizontal direction, and among the structures of the inspection facility, the horizontal hanger and the reinforcing means for preventing separation are inserted in different directions (right angle) to the horizontal outer binding protrusion, respectively. bound,
On the lower side of the side wall of the pier, the four-way binding bracket is installed in the vertical direction, and the vertical support and the inner handrail among the structures of the inspection facility are inserted and bound in different directions (right angle) to the outer binding protrusion in the vertical direction, respectively.
The four-way binding bracket is installed in a horizontal direction in parallel with a certain distance from the vertical direction four-way binding bracket, and the outer handrail is arranged at a right angle at regular intervals in the horizontal direction on the outer binding protrusion in the horizontal direction. While being inserted and bound to the pier, it is inserted and bound to the inner central septum of the four-way binding bracket on the side wall of the pier in the vertical direction,
At a predetermined distance from the support, the handrail in the vertical direction is inserted and bound with respect to the inner central separation of the four-way binding bracket in the lower horizontal direction,
All of the structures of these inspection facilities are inserted and bound with respect to the four-way binding bracket regardless of the position and direction and bolted, so that the four-way binding bracket is basically fastened with a binding bolt and a binding nut to each outer binding protrusion on the four sides. A four-way binding bracket of a single binding means for a hanging bridge inspection facility, characterized in that a plurality of bolt holes are formed through it.
