摘要： PROBLEM TO BE SOLVED: To simplify a structure of a soil retaining panel and improve the ease of use by fixing a binding plate at a position where a groove opening in an end part of a vertical beam having a groove fixed on fringes on both sides of a face plate is blocked and providing a connection pin of upper and lower panels in an end part of the vertical beam by utilizing the binding plate. SOLUTION: Vertical beams 1, 1 are fixed in the vertical direction along fringes on both sides of an inner face of a face plate which is formed in such a manner that it has the same size and shape as a soil retaining panel and a plurality of horizontal reinforcing rigid members 2 are fixed in parallel across an interval in the right and left directions and in the vertical direction between the vertical beams 1, 1 on the right and left. The vertical beam 1 is provided with a groove 16 of which front is opened in the vertical direction, and a binding plate 4 is fixed at a position where an opening of the groove 16 in an upper end part and a lower end part is blocked by welding. A connection pin 7 which connects soil retaining panels which are accumulated in the vertical direction is provided in such a manner that it faces up or down in at least one part of the upper end part and the lower end part of the vertical beam 1 by utilizing the binding plate 4. The connection pin 7 is inserted into the groove 16, and a set screw 6 is inserted into a through hole 4a in a condition in which a stopper comes into contact with an end face of the vertical beam 1 and is screwed in a screw hole of the connection pin 7.

摘要： PROBLEM TO BE SOLVED: To simplify structure and to make manufacture and execution of work easy by a method wherein channel steels or the like are fixed to both ends of a sheathing plate protecting a side wall of an excavated trench while a reinforcement member is fixed at the center, and vertical frames are formed therewith while the sheathing plates are being heaped up. SOLUTION: Channel steels each having a projected fitting part and a recessed fitting part at its upper and lower part are fixed back to back to both sides of a horizontal stiffness reinforcing member (sheathing plate) 2 made up of a beltlike steel plate or the like by bend-forming, and a reinforcement member 1' made from a channel steel is fixed at the center. The sheathing plates 2 in plural numbers are installed in heaping-up at a side wall of an excavated trench for laying portable water pipes, sewer pipes or the like therein, and thereby a sheathing panel 10 is formed. With the shathing plates 2 heaped up on installation, the projected parts and the recessed parts of the channel steels on both sides are fitted together and a vertical beam 1 is formed thereby while the reinforcement members 1' at the center are connected together to form a vertical beam. Connecting parts of the channel steels are fixed with pins or connecting metal fixtures. The structure of the sheathing plate 2 is simplified while the number of component parts are reduced, making manufacture and transport easy. Thereby, sheathing works can be executed efficiently.

摘要： PROBLEM TO BE SOLVED: To improve efficiency in execution of work by a method wherein a sheathing panel is formed with jack connecting members and distance adjustment members provided at both ends of face plates attached to the surface and the reaverse side of skelton frames formed into a gridlike shape, and the panels are heaped up along a side wall of an excavated trench. SOLUTION: Skelton frames 1' and 2' are attached in a gridlike shape to a space formed by vertical beams 1 and horizontal beams 2 and face plates 3 are stuck to the surface and the reverse side of the skelton frames while jack connecting members 4, distance adjustment members 5, projected fitting members 6 and the like are provided at both ends of the face plates, and thereby an edge-equipped sheathing panel 10 is formed. The sheathing panels 10 in plural numbers are installed in heaping-up at a side wall of an excavated trench for laying potable water pipes, sewer pipes or the like therein. On installation, recessed fitting members of the sheathing panel that comes to the upper tier are fitted onto the projected fitting members 6 at both ends, and both of the panels are connected together with pins or the like inserted through pin holes 6a. The sheathing panels are heaped up similarly until they get to a specified height equivalent to the depth of the trench. Therefore, the structure is simplified for the sheathing panel while the number of component parts therefor is reduced, making manufacture and transport easy. Thereby, sheathing work can be executed efficiently.

CONSTITUTION:T-shaped hooks 15a and 29a of an interlocking member 15 of the basic end spindle receiver 16 and an interlocking member 29 of the front end spindle receiver 30 are fitted in longitudinal slots 1b of guide rails 1 and 1, and they are turned to 90 degree so as to prevent them from loosing. Wedges 14 and 28 are driven, and the interlocking members 15 and 29 are made to adhere to the guide rails 1. After that, a pivot section 8 of a coupling device 9 connected to one end of a spindle main body 4 is connected to a pivot section 11 of the receiver 16 with a pin 10. The other end thereof is covered with a coupling device 23 connected with a pin 17, and both ends are interlocked with both outsides of a cylindrical body 25 in which a pin 24 is inserted. After that, a cylinder of the main body 4 is operated and is expanded, and the guide rails 1 and 1 are maintained in specific trench width. In addition, the main body 4 is sufficiently supported by the long vertical turning support section. According to the constitution, piping work efficiency of the pipe can be promoted.

摘要： PURPOSE:To control the erosion for the stream bed by preventing the run-off of gravels by a method in which a water-permeable dam structure is constructed in the stream bed, a well frame of steel netting is buried in the sand deposite upstream of the dam structure, and a culvert is provided around the well frame. CONSTITUTION:The stream bed 5 is excavated, a concrete footing 6 is constructed, and a water-permable steel frame 7 of a triangle cross section is built up on the concrete footing 6 to construct a dam structure 8. When coarse gravels are refused by th screens 14 and 14' of the steel frame 7 and soil, sand, and gravels are deposited to an extent, sand deposite 17 is excavated in the upstream of the dam structure 8, the well frame 18 of steel netting is set in the stream, and coarse gravels are packed into the inside of the well frame 18. Coarse gravels are placed around and the upside of the well frame 18, a culvert 19 is constructed, and the well frame 18 is buried. Thus, part of water flowing from the upstream of the well frame 18 is directed into the well frame, gradually discharged into the sand deposite 17, and spread.

摘要： PROBLEM TO BE SOLVED: To make the construction work easier in a narrow space when clamping from the outer periphery for reinforcing a rectangular column formworks. SOLUTION: A formwork clamp device comprises two lateral joists 11 facing each other around the rectangular column formwork 8 and two lateral joists 12 facing each other is the direction perpendicular to the joints 11. Each lateral joist 11 or 12 comprises a lever member 15 or 18 contacted to the outer surface of the column formwork 8 and a truss 17 or 20 fixed to the outer side surface of the lever member 15 or 18 in a detachable manner. Connections of these members are performed with bolts and nuts for example. The lateral joists 11 and 12 have trusses 17 or 20 in construction so that a sufficient strength can be obtained with a light weight. Also, the trusses 17 and 20 can be separated from the lever members 15 and 17, so that individual member can be made to a small size and a light weight. Therefore, even tough a working area is narrow as in the case where scaffolding for frameworks is located around it, the members can be carried in easily and the work can be performed easily. If the trusses 17 and 18 are made of a plurality of truss pieces 16 and 19 in construction, then individual member can be made much lighter.
