Description

Safety installing structure of main column for inspection passage {Safety installing structure of main column for inspection passage}

The present invention relates to a safety installation structure of a main post for an inspection road for a bridge inspection route, and in particular, an anchor unit is installed on the pier (alternate) side by an inspection that is detachable in a construction method without iron removal or perforation. Since the main post anchor unit is firmly attached to the bridge by inspection from the iron removal work, construction is possible at the set location of the pier, and after the removal of the iron removal work, the installation of the main post is performed through the main post anchor unit as an inspection. It is related to the safety installation structure of the main post for the inspection route for the bridge inspection route in which the main post is buried in the main pier by coupling and is firmly coupled to the main post anchor unit.

In general, an inspection path is installed in the lower part of the bridge after completion of the construction of the bridge in the bridge pier for future inspection and maintenance of the bridge support. A roadway or sidewalk is installed on the upper slab of the pier, and an inspection path, which is a passage for inspection of the pier, is installed in terms of maintenance and management of the pier.

In order to prevent accidents such as falls due to carelessness when the inspector walks, the main post is installed preferentially to install railings outside the pier. Of course, a footrest that can be passed by workers is installed in the main post. As such inspection paths are simply cut and installed by a welding method by simply cutting the length of steel, the load occupied by the inspection table in the pier is excessive, affecting the design load of the bridge. A post-coating process is required, and there is difficulty in maintenance after installation. In other words, in addition to the main pier inspection, there is an inconvenience in the management work according to the inspection items of the railing for this purpose. Therefore, in recent years, a product that makes it easy to assemble a scaffolding on a railing post made by stamping it in a sand casting type of aluminum material, and has a light weight and good corrosion resistance, has been used.

On the other hand, the main pillar must be firmly and safely installed on the pier for the inspection route facility. For example, when scaffolding is installed, there is a problem that safety is deteriorated and the construction period is prolonged due to high place work.

As a background technology of the present invention, as Korean Patent Registration No. 10-0353882, a'fixing device for installing an inspection table on a pier' has been proposed. This includes rails having guide grooves on the front and rear sides of the longitudinal direction that are buried and installed at regular intervals up and down at a fixed position of the slab of the pier, a bolt through which a head is inserted into the guide groove of each rail, and the bolt is vertically fixed. In order to maintain the gap, a spacer piece having a hole through which the rod of a bolt passes through the upper and lower parts at regular intervals, and a nut is fastened to the rod of the bolt to fix the spacer piece, and guided to the guide groove to It is in contact with the reinforced vertical reinforcing bars and is fixed with welding or binding strings, and a sealing inserted in the front guide groove to prevent filling when concrete is poured into the pier slab formwork, and the guide groove in which the sealing has been removed after the pier slab is placed is a means of fixing objects. , It characterized in that it consists of a nut that penetrates and fixes the object to the bolt that the head is inserted and guided.

However, in the above background technology, it is difficult to accurately install a fixing device at a set position because there is no technical means for firmly fixing the position of the rail before concrete pouring when it is embedded in the pier.

As another technology that serves as the background of the present invention, as Korean Patent Registration No. 10-1453065, a'assembled bridge inspection railing' has been proposed. This is because the railing has a structure in which the railing is installed on the pier through an anchor, so not only may vibration cracks occur in the pier due to the drilling work of the pier for anchor construction, but also it is difficult to trust the anchor fixing force.
