BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold plate connecting member for connecting scaffold plates and a passage formed using the scaffold plate connecting member.

[0002]

2. Description of the Related Art In the construction of a tunnel using a shield excavator, the earth and sand excavated at the tip of the tunnel are conveyed backwards and discharged, and materials and equipment are conveyed to the tip of the tunnel. It is common to have a track vehicle that can reciprocate in the axial direction of the tunnel. On the other hand, in the tunnel, it is necessary to form a passage through which a worker can walk.In this passage, a large number of scaffolding plates are connected to the sleepers of the railroad vehicle by scaffolding clamps or number lines. It is formed by installing.

[0003]

By the way, in recent years, in the construction of a tunnel using a shield excavator, an AGV (Automatic, Guided, Vehicles) system is adopted in which a traveling wheel is a tire system and automatically travels instead of the track vehicle. The one adopted is known. This is to install a high-frequency voltage-guided wire on the downhole segment to automatically steer the traveling vehicle using electromagnetic induction, and to send signals such as start and stop by the induction wireless transmission system. , Enables automatic control operation of the entire system.

Therefore, in the AGV system, there is no sleeper as in the rail car system, and a scaffolding plate cannot be installed on the sleeper to form a passage. Was there. In other words, when constructing a tunnel using a shield excavator, since the tunnel cross section is circular, it is difficult to form a passage having a horizontal walking surface over the entire length of the tunnel, and the passage is If you try to form by connecting many scaffolding boards, you can not connect the scaffolding board on the sleepers, so with conventional scaffolding clamps and number lines, it takes time and labor to connect the scaffolding boards stably. Difficult to do.

The present invention has been made in view of the above circumstances, and can easily and reliably connect a large number of scaffold plates when the AGV method is used in the construction of a tunnel using a shield excavator. It is intended to provide a scaffolding plate connecting member and a passage formed by using the scaffolding plate connecting member.

[0006]

In order to achieve the above object, the scaffolding plate connecting member according to claim 1 of the present invention connects upper and lower plates which are vertically spaced apart from each other in parallel with each other. The upper and lower plates and the connecting plate are formed of a connecting plate, and a pair of concave grooves facing in opposite directions are formed.

A scaffold plate connecting member according to a second aspect of the present invention is the scaffold plate connecting member according to the first aspect, wherein the length of the groove is set to be at least twice the width of the scaffold plate to be connected.

The passage according to claim 3 is not substantially L-shaped, and both ends thereof are fixed to the inner wall surface of the tunnel, so that the support member having one side horizontally provided at predetermined intervals in the axial direction of the tunnel. The scaffolding plate connecting member is arranged on one side of these supporting members so that the pair of concave grooves are arranged in the axial direction of the tunnel, and each end of the scaffolding plate is adjacent to the axial direction of the tunnel. The scaffold connecting member is inserted into the mutually facing concave grooves.

[0009]

In the scaffolding plate connecting member according to the first aspect of the present invention, the scaffolding plates can be easily and reliably connected by inserting the ends of the scaffolding plates to be connected into the pair of recessed grooves facing in opposite directions. Can be connected. In addition, a plurality of scaffolding board connecting members are installed at predetermined intervals, and the scaffolding boards are easily inserted to connect the scaffolding board connecting members from the lateral direction into the mutually facing concave grooves of the scaffolding board connecting members. To form a passage.

In the scaffolding plate connecting member according to a second aspect of the present invention, the length of the groove is at least 2 times the width of the scaffolding plate to be connected.
By setting the scaffolding plate more than twice, it is possible to insert two or more scaffolding plates in the lateral direction into the groove, so that the scaffolding plate should be two
Connections can be made in more than one row, which allows the width of the passages to be increased to more than one row. In addition, a plurality of scaffolding plate connecting members are installed at a predetermined interval, and by inserting two or more scaffolding plates from the lateral direction in the concave grooves facing each other of the adjacent scaffolding plate connecting members while sequentially sliding, A plurality of scaffolding boards can be easily connected laterally and longitudinally to form a passage having a width of two or more rows.

According to the third aspect of the present invention, since the support member has a substantially L-shape, one end of the support member is made horizontal by fixing both ends of the support member to the inner wall surface of the tunnel. Can be placed. Therefore, a large number of supporting members are arranged at predetermined intervals in the axial direction of the tunnel, and the scaffolding plate connecting member is arranged on one side of each supporting member so that the pair of concave grooves are oriented in the axial direction of the tunnel. By inserting the respective end portions of the scaffolding plates into concave grooves facing each other of the scaffolding connection members adjacent to each other in the axial direction of the tunnel, a passage formed by simply and stably connecting a large number of scaffolding plates is formed. be able to.
