である。Description: TECHNICAL FIELD The present invention relates to a joint structure of an itching plate used for a work passage at a shield construction site or the like.

ネルを完成させて行く。The shield method is used when constructing subways, water / sewerage systems, and electric power / telegraph facilities to be built in the underground space of the city. The shield mainly consists of steel shell plate (skin plate) and built-in propulsion jack. After pushing the shield into the soil and excavating the sand of the face that hits the front of the shield for a segment length, assemble the segment 1 ring and take the reaction force to this segment to propel the shield by the next ring by the shield propulsion jack. Then, the segment is assembled again. During this time, backfill material is injected into the skin plate of the shield and the gap of the segment to fill the void on the back of the segment to complete the tunnel.

易いように多数のあゆみ板が連接して布設されている。By the way, at such a shield construction site, a battery car and a zlitro are used to discharge excavated soil, and a worker walks and works between a pair of tracks on which the battery car and the zlitro run. For ease of operation, a large number of Ayumi plates are connected and laid.

場コストが上がる。By the way, the conventional sluice board does not consider the segment length (sleeper pitch) in the shield work and is long (3 to 4 m). There was a problem that it could not be laid and the work efficiency of the laying was poor, and in addition, the safety of the scaffolding at the tip of the mine could not be secured. In addition, since the wooden itching boards are laid by connecting them by overlapping and wrapping the ends, there is a level difference (21 to 40 mm) corresponding to the thickness of the itching board at the wrapping point, and falls during walking. Not only will it lead to an accident, but it will cause a balance accident if the wrap location is not set on the sleeper, resulting in a loss of the effective length of the laying for the product length, resulting in poor laying efficiency, and it is difficult to prevent slipping. Therefore, there is a risk of falling accidents due to slippage when soil and sand containing water adhere. Next, since the end portions of the steel and synthetic resin adjoining plates are connected to each other by inserting them, there is no fall accident due to steps such as wooden adjoining plates and loss of the effective length of installation for the product length. However, it is difficult to temporarily remove the intermediate part during cleaning and confirmation of the surveying point in the mine, it takes time to clean, and it is difficult to lay the surveying point installation location. The device has been devised to prevent slippage, but it has not come to the full effect. Further, it is difficult to repair the joint portion of the synthetic resin eddy plate at the time of diversion, the diversion efficiency is poor, the product price is high, and the site cost is high.

板を取外すことが非常に困難である。In addition, there is a steel itinerating plate with expanded metal stretched on the step surface.Since earth and sand etc. do not fall downward and are not deposited on the step surface, a high anti-slip effect is obtained and slippage is prevented. Although it is possible to prevent a fall accident due to the above, since the end portions are connected by being inserted, it is very difficult to remove the swaying plate in the middle when connecting these sequentially.

You can In addition, an L-shaped stopper is provided on the lower surface of one end of the adjoining plate, and a clip formed by bending a round bar into a U-shape is slidable on both sides of the other end on both sides of the pipe. A slide clip formed by inserting the L-shaped stop fitting into the flange portion of the sleeper to lock the slide clip, and the clip portion of the slide clip is driven into another flange portion of the sleeper to clamp the flange portion. By doing so, the Ayumi board is fixed to the sleepers and jointed, so even if the Ayay board is being installed, it can be easily removed temporarily, which is very convenient for cleaning and checking the survey points. Even if the side of the plate is narrow, it can be easily installed and removed, which is convenient when laying the flexible plate between a pair of tracks. Therefore, according to the joint structure of the working path sway plate according to the present invention, higher safety is obtained,
In addition, it is possible to improve work efficiency in a narrow mine.
