Description

Build-on inspection equipment for fixity of bridge

The present invention relates to a bridge inspection facility, and in particular, the fixed bridge inspection facility is characterized by the assembly type.

The bridge inspection facility provided for the inspection of the lower surface or bridge device of a conventional bridge includes a stationary inspection facility fixed integrally around the bridge, and a mobile inspection facility having self-propelled means for moving between the bridge and the bridge at the bottom of the bridge. There is this.

In the above configuration, the configuration and installation method of the fixed inspection facility is to fix several fixing brackets at a predetermined interval around the top of the pier with an embedded bowl, and then fix the horizontal feet to each of the several fixing brackets by welding. , Weld fixing the horizontal row support on the inner end and the outer end side between the horizontal support, and welding the edge support on the middle outer side to some side pedestals by welding to form a rectangular support frame all around the piers. Steel plate, perforated plate, and perforated net are applied to the upper surface to form a scaffold, and the outer end is fixed by welding a vertical support rod to the upper end of the pedestal by welding, and then the horizontal rail or safety net is welded between the support rods. It was fixed by the structure and formed into a handrail.

Such a fixed bridge inspection facility, except for the components and the installation method, except for a fixed bracket which is fixedly installed by a buried bolt on the upper outer surface of the pier, and a support rod of a handrail fixed to the upper end of the horizontal supports. All members are cut and processed at the construction site in accordance with the installation process between the fixed brackets or the horizontal supporters, which is the first process, and then the horizontal supporters, the horizontal supporters, the corner supporters, the footrests and the handrails are installed after the fixing brackets are installed. It is a configuration that is installed by the site-fitting construction to be fixed integrally by the welding work annually, there were a number of problems in the maintenance and maintenance after construction as well as during ordering and construction.

The first problem is that although most bridge pier standards are standardized in several types, the existing fixed bridge inspection facilities are constructed and configured as on-site and welded fixed as described above. Standardization, construction quantity and standardization of construction work are difficult.

If the standard, construction quantity and construction work of the bridge inspection facility member are de-standardized, the construction orderer shall newly prepare the ordering specification of the inspection facility, construction quantity and construction cost and construction cost for each construction order. Very inefficient in terms of

The contractor also had difficulty in predicting the requirements of the materials and the construction period before the contract was received. Therefore, it was very difficult to purchase construction materials, manage the construction personnel, and distribute the construction work. It takes a lot of time to prepare for the construction, and many processes are custom-made even during the construction work. Therefore, the raw materials of all parts must be transported to the site and then cut and processed step by step according to the process at the site to be fixed by welding. There were problems such as rise, waste of raw materials, excessive site construction facilities, and air delay due to phased construction.

The above problems make it difficult to control the quality management and construction of the contractor as well as the client, thereby increasing the production cost and equipment cost.

The second problem is that the inspection facility is configured to fix all the components by welding, which requires considerable paint cost and process by coating the rust-preventive paint on these welded parts, resulting in high construction cost and continuous maintenance after construction. There was a disadvantage that the painting work should be performed and the aesthetics were poor, and the connection of each member in repair, maintenance, etc. Formed by this welding fixed type, there is a problem that the partial repair work is difficult and the work cost is also considerably high.

The third problem is that the existing fixed inspection facility had a lot of components, and there was a factor of increase in raw material cost and construction cost due to this, and it was difficult for mass production because all members had to be manufactured by welding separately for each construction. Supply and quality control was difficult.

The present invention is provided to solve the problems of the existing fixed inspection facilities as described above, by simplifying the components in forming the fixed bridge inspection facilities, standardizing the members and construction work, and composed of assembled materials, The purpose is to reduce the cost of equipment by standardization of construction and standardization, and to provide an assembly-type fixed bridge inspection facility that can improve the work efficiency of air shortening, construction start-up, order quality control and construction quality, and inspection work.

14 to 15 show the structure of the assembled stationary bridge inspection facility 100a according to another embodiment of the present invention.

This configuration is a type that is installed in the pontoon pier of the railway bridge, all components and their prefabricated technical configuration is the same as the prefabricated fixed bridge inspection facility 100 of the above embodiment, but only the pontoon pier is train Due to the fact that the left and right lengths are slightly longer than those of the main piers, it is not possible to form a protruding passage on the left side of the top of the piers, and thus the configuration of the left pedestals of the right side pedestals 30c and 30d of the embodiment is described. The configuration formed in the same way as the configuration is different, and accordingly, the longitudinal dimension of the floor deck 50 provided on the back of the pier increases, and the quantity of the floor deck 50 provided on the left side is different only in the configuration of decreasing.

One embodiment of the present invention as described above is a configuration applied to one form of the bridge for railroad bridge, the configuration of the present invention is not necessarily limited to the one embodiment. For example, in the case of railway bridges, the same components may be used in different types of planes or road piers. In the case of increasing or decreasing the width direction of the inspection passage to a specific standard, the length of the pedestals can be standardized according to the standard formed in multiples of the floor deck width standard of the standardized bout. In addition to the means for fixing the fixing piece at the bottom, or bolts, nuts can also be fixed.

As described above, the assembled fixed bridge inspection facility of the present invention has a simplified component, with fixed brackets and basic pedestals, left and right side pedestals, corner rests, and ready-made floor decks, handrails, and the like. In comparison with the conventional field-fitting welding fixed inspection facility, it is constructed to be prefabricated by bolts and nuts annually to the fixing bracket.

An important effect is to standardize the subsidiary materials and construction amount that make up the inspection facility in several ways according to the type of piers.

When the inspection facility member and the construction quantity are standardized, the construction orderer can streamline the ordering work by eliminating all the inefficient elements of the facility design and ordering specification for each construction order.

The contractor can mass-produce the subsidiary materials, lower the production cost, facilitate the supply and demand of raw materials and construction materials, and standardize the construction work.

In addition, the construction company can predict the required amount and construction period before the order is received. Therefore, it is very easy to purchase the construction materials, manage the construction personnel, and distribute the construction work. It can be started by this company, and even during the construction work, the inspection facility members standardized in the factory can be transported to the site to complete the construction by simple bolt and nut assembling process. It can reduce the transportation cost and labor cost, and reduce the construction cost by simplifying the construction equipment.

As the construction details are simplified, the client can easily manage supervision during construction and quality control in construction.

Another effect is that the construction of the inspection facility is prefabricated in the field rather than on-site welding, so that the rust-preventive paint should be painted on the welded area in the conventional construction and periodically painted for maintenance after construction. Significantly lowers construction and maintenance costs by eliminating paint and process costs.

After repairing, the bolts and nuts can be loosened only at the connection part of each member to repair or maintain the member due to partial damage of the inspection facility or deterioration of some members. Since repair and replacement work can be carried out, this part also has the effect of saving considerable maintenance work costs.

In addition, the outer surface of the inspection facility by the closing plate has the effect of making the appearance beautiful compared to the conventional configuration.
