  FIG. 13 is a view for explaining the coupling in the state III in FIG. 6, that is, the case where the end portion of the lining plate 100 is located on the lining girder 120 of the H-shaped steel column at the terminal portion of the construction site. FIG. 13A is a front view of the end portion of the lining plate 100, and FIG. 13B is an enlarged perspective view of the end portion of the lining plate 100.

  In this structure, the two lid portions 130 and 131 cover the end portion of the lining plate 100. The cover part 130 covers the upper part of the edge part of the cover board 100 from the upper surface side. It is almost the same as the lid portion 110A described earlier with reference to FIG. 11 except that the length in the axial direction is different.

By slidably moving along the portion 203 to a predetermined position, it is possible to couple with the lining girder 120 at an intermediate position of the lining plate 100. At this time, the work from the upper side is possible by removing the front plate 210 of the main body.

  Next, FIG. 17 is a diagram illustrating a structure for connecting the cover plates 100 adjacent to each other in the axial direction in the second embodiment.

  In FIG. 17, the end faces of two lining plates 200 adjacent in the axial direction are positioned on the upper flange of the lining girder 120 together. Further, a steel frame 205 similar to that of the square pipes 200a to 200d is inserted into each of the square pipes 200a to 200d. Therefore, the connecting member 207 described above with reference to FIG. 15 provided on each end face of the square pipes 200a to 200d has a through hole into which the frame body 205 is inserted.

  The frame body 205 has a length inserted across both adjacent square pipes, and has a rectangular cross section corresponding to the square pipes 200a to 200d.

  The inserted frame body 205 and the corresponding square pipes 200a to 200d can be connected to each other by a connecting structure 206 such as fixing with bolts and nuts.

  18 and 19 are diagrams for explaining an example of a connection structure 206 between the inserted frame body 205 and the corresponding square pipes 200a to 200d.

  FIG. 18 shows an example in which a square pipe and a frame are connected and fixed with bolts and nuts. A through hole 205a is formed in the frame 205, and a nut 206a is fixed to the inner surface side in advance. On the other hand, through holes 205b are formed in the square pipes 200a to 200d corresponding to the positions of the nuts 206a. Therefore, the bolts 206b are inserted through the through holes 205b of the square pipes 200a to 200d corresponding to the nuts 206a of the inserted frame body 205, and screwed into the nuts 206a to be fixed. Thereby, the connection between adjacent lining boards is possible.

  Here, in the example of FIG. 18, the bolt 206b and the diameter of the through holes 205a, 205b formed in the frame 205 and the square pipes 200a-200d are inevitably toleranced, so that the bolt and nut can be firmly fixed. Even if it exists, backlash may arise in the connection fixation of the square pipes 200a-200d of the lining board 100, and the frame 205. FIG.

  FIG. 19 shows another example of fixing with bolts and nuts, and is a structure that can reduce the possibility of looseness in connection and fixation with respect to the configuration of FIG.

  In this example, a through hole 205 a is provided on the side surface of the frame body 205. On the other hand, nuts 206a are fixed to the outer surfaces of the square pipes 200a to 200d corresponding to the through holes 205a of the frame 205. When fixing, the bolt 206b is screwed into the nut 206a, and the pointed end 206d of the bolt 206b serving as the shaft member is allowed to exist in the through hole 205a on the side surface of the frame 205 so as not to penetrate.

  Further, when a lock nut 206c that is screwed into the bolt 206b is provided so as to be stacked on the nut 206a, the bolt 206b has a pointed shape and applies a pressing force to the through hole 205a on the side surface of the frame 205. Thereby, the square pipes 200a to 200d corresponding to the frame body 205 can be fixed without backlash.

  FIG. 20 is a diagram illustrating a configuration example for connecting the lining plates adjacent to each other in the lateral direction as described above by connecting them in a wrong manner.

  14 is a pin-like protrusion formed on the side surface of the outermost square pipe among the square pipes constituting the lining plate 100, but the configuration shown in FIG. Operability is improved by the pin 113 formed in a movable manner.

  That is, FIG. 20 (1) shows a state in which the connection between the left and right lining plates 100A and 100B adjacent to each other in the horizontal direction is released, and FIG. 20 (2) shows the lining plates 100A and 100B adjacent in the horizontal direction. The state which connected between is shown.

  The pin 113 is provided with an urging means 113b and a hooking portion 113a formed by being bent into a hook shape on the rear end side. On the other hand, an engaging portion 114a formed in the locking plate 114 that allows the latching portion 113a of the pin 113 to be inserted and latched at an appropriate portion against the biasing means 113b.

  Therefore, when the connection between the lining plates 100A and 100B is released, the pin 113 is retracted against the urging means 113b, and the tip is inserted from the hole 200c formed in the square pipe 200d of the adjacent lining plate 100B. Is pulled out, and the latching portion 113a is locked to the engaging groove 114a. Thereby, the release state is maintained.

  When connecting the lining plates, the latching portion 113a of the pin 113 is removed from the engaging groove 114 in advance, and the tip of the pin 113 is protruded. As a result, when the lining plates 100 are continuously aligned and arranged, the connecting operation is particularly easy.

  According to the present invention described above, it is possible to provide a connection structure and a connection structure for a lining plate which can be reduced in weight and can be easily connected to a lining plate and a connection between adjacent lining plates and to a lining girder. Furthermore, in the second embodiment, the worker can work from the upper surface side of the lining plate to fix the lining plate to the lining girder.
