[Other Embodiments of Door Structure]
In the door structure 1 provided with the mounting bracket 27 according to the present invention described above, the pipe-like rail 6a is laid below the entrance / exit m of the greenhouse H (below the entire width of the door body M) as shown in FIG. Although the embodiment has been shown, the door structure 100 according to the embodiment described below may be used.

  First, in FIG. 12, the pipe-shaped rail 6 using the mounting bracket 27 is laid so as to be slightly positioned on the end side of the door main bodies Ma and Mb. That is, the protruding portion 105 is formed by slightly projecting the pipe-shaped rail 6 to the door main bodies Ma and Mb from the vertical column lower ends 4-1 of the vertical columns 4 and 4 erected on the left and right of the house entrance m. Yes. Further, a region without the pipe-shaped rail 6 is a rail-less portion 106.

  When the pipe-shaped rail 6 is laid in this way, even if the door body M is opened and closed to the left and right in a normal use state, the protruding portion 105 of the pipe-shaped rail 6 falls within the range corresponding to the width of the door body M. The pipe-shaped rail 6 can be surrounded by the inner and outer plates 18 and 19 of the frame 10 (base frame K). That is, the door main body M can be guided so as to be slidable to the left and right even if the lower portion of the house entrance m is the rail-less portion 106. In this description, the protruding portion 105 is formed, but the protruding portion 105 is not provided, and only the mounting bracket 27 may be used.

  Further, when the door main body M is closed by providing the rail-less portion 106, the pipe-shaped rail is formed by the inner and outer plates 18 and 19 of the base frame K in the vicinity of the central portion of the house doorway m where the left and right door main bodies Ma and Mb abut. 6 is not surrounded, there is a possibility that the movement of the door main body M becomes unstable due to the influence of the outside wind or the like, or swaying at the time of sliding.

  In such a case, as shown in FIG. 13, when the door main body M is closed, a part of the lower edge of the door main body M is guided from the front and rear to the ground G side which is the central portion of the wife surface.

  The guide locking unit 140 is disposed on the track where the lower edge of the door body M slides, and the end surfaces of the left and right door bodies Ma and Mb abut when the door body M is closed. Two guide locking units 140 are arranged to face each other so as to straddle the position.

  Note that the distance between the inner sides of the guide plates 141 and 141 of the guide locking units 140 and 140 arranged opposite to each other is set to be approximately the same width as the width of the door body M in the thickness direction, thereby holding the door body M without play. Can be locked.

  As described above, by configuring the guide locking units 140 and 140, the lower frame 10 of the door main body M is necessarily involved with either the guide locking units 140 and 140, the protruding portion 105, or the mounting bracket 27. Therefore, it is possible to restrict the door body M from being tilted in and out of the greenhouse H also by the influence of the outside wind on the door body M and the influence of positive / negative pressure in the greenhouse H.

  Further, since most of the lower portion of the house entrance / exit m is the rail-less portion 106, it is possible to prevent a worker from getting caught in the pipe-shaped rail 6 when the worker enters / exits the house entrance / exit m, and to bother the pipe. A cart (not shown), a tractor (not shown), etc. can be moved into the greenhouse H without removing the rail 6.

  Here, the pipe connector 91 that can be easily connected when the pipe-shaped rail 6 needs to be connected will be described with reference to FIGS.

  The pipe connector 91 is particularly effective, for example, when it is desired to construct the pipe-shaped rail 6 on the railless portion 106 described above. In FIG. 7, the end portion of the protruding portion 105 is inserted into about half of the area inside the pipe connector 91, and the pipe-shaped rail 6 a is inserted into the pipe connector 91 so that the end surface of the pipe-shaped rail 6 a comes into contact with the end surface of the protruding portion 105. insert. Then, two pipes can be connected by screwing butterfly head bolts 92 and 92 screwed to the pipe connector 91.

  The two pipes can be brought into contact with each other at the center of the pipe connector 91 by working while visually confirming the end portions of the two pipes from the confirmation hole 93 formed in the center portion of the pipe connector 91. .

  Specifically, as shown in FIG. 15, the pipe connector 91 is formed by a pipe insertion part 94 formed in a cylindrical shape with both ends opened, and projecting from the outer peripheral wall of the pipe insertion part 94 along both openings. The bolt insertion wall 95 has a rectangular cubic shape, and the pipe insertion portion 94 has an insertion hole 97 through which the pipe-shaped rail 6 can be inserted, and is formed at the center of the outer peripheral wall facing the bolt screwing wall 95. A confirmation hole 93 penetrating the insertion hole 97 is formed, and the bolt screwing wall 95 has pipe fixing female screw holes 96 and 96 penetrating the insertion hole 97 in the vicinity of both openings of the insertion hole 97.

  The pipe connector 91 configured in this manner can connect two pipes with the bolt screwing wall 95 disposed below, so that the upper part can suppress a step with the pipe-shaped rail 6, and the pipe shape Since the curved surface integrated with the rail 6 can be formed, the door body M can be smoothly and slidably guided without contacting the inner and outer plates 18 and 19 of the lower frame 10.

  Further, since the bolt screwing wall 95 is formed in a rectangular cubic shape and has a certain thickness, a high-strength tap can be formed in the pipe fixing female screw holes 96.

[Effect of mounting bracket]
As described above, the mounting bracket 27 according to the present embodiment and the door structure 1, 100, 200 have been described. However, the mounting bracket 27 according to the present invention is provided when the pipe-shaped rail 6 is laid at the entrance / exit m of the greenhouse H. The rail insertion and fixing portion so that the axis of the rail insertion hole 81 formed in the rail insertion and fixing portion 29 on the left and right vertical columns 4 and 4 erected on the left and right of the doorway m through the spacer mounting base frame 28 is substantially horizontal. 29 is erected, and the pipe-like rail 6 is inserted into the rail insertion hole 81 and is formed in the rail insertion fixing portion 29 and is formed in the pipe shape via the rail fixing bolt 83 by the rail fixing female screw hole 82 passing through the rail insertion hole 81. Since the pipe-shaped rail 6 can be fixed to the left and right vertical columns 4, 4 by pressing and fixing the outer peripheral surface of the rail 6, a plurality of pipe-shaped rails 6 are connected with an extremely simple structure of a single member. The pipe-shaped rail 6 can be fixed very simply simply by inserting the pipe-shaped rail 6 through the rail insertion hole 81 and pressing and fixing with the rail fixing bolt 83, thereby improving the assembly workability. Can do.

  Further, since the pipe-like rail 6 can be used as a guide when the door body slides, gravel, rainwater, snow and other foreign matters do not enter the inside of the pipe-like rail 6 and are advantageous in terms of corrosion damage. Since the pipe-like rail 6 has a curved surface shape, these foreign substances are unlikely to accumulate on the pipe-like rail 6, and the smooth sliding of the door main body M can be maintained for a long time.

  Further, even if a load is applied to the pipe-shaped rail 6 from the outside, the pipe-shaped rail 6 uniformly distributes the load, so that the pipe-shaped rail 6 is not easily deformed, and the smooth sliding of the door body M can be maintained for a long time.

  In addition, the mounting bracket 27 divides a spacer mounting base frame 28 for fixing to the vertical column 4 and a rail insertion fixing portion 29 for connecting and fixing the pipe-shaped rail 6 and for guiding the door body M in the vertical direction. Thus, the guide structure on the door body M side can be constructed without being affected by the fixing of the mounting bracket 27 to the vertical column 4.

  Furthermore, the strength of the rail insertion fixing portion 29 formed integrally with the spacer mounting base frame 28 is high, and the door main body M can be guided slidably to the left and right with only the mounting bracket 27.

  Further, the spacer mounting base frame 28 is formed to have a predetermined cross-sectional rectangular length, and the spacer mounting base frame 28 and the spacer mounting base frame 28 are surrounded by the front and rear walls 30, 31 of the spacer mounting base frame 28 by surrounding the left and right vertical columns 4, 4.

  In addition, the rail insertion fixing portion 29 is offset and connected to the rear wall 31 side of the spacer mounting base frame 28, and the rail insertion hole 81 is formed in a substantially annular shape. Since the rail insertion and fixing portion 29 is disposed so as to be separated from the back surface, the pipe-shaped rail 6 can be installed with a predetermined amount away from the vertical column 4 and the position of the door body M with respect to the vertical column 4 can be easily moved to an appropriate location. Can be arranged.

  The rail insertion hole 81 has an upper half forming a rail abutting wall 84 having substantially the same curvature as that of the pipe-shaped rail 6, and a lower half facing the upper surface 85 of the spacer mounting base frame 28. Since the offset space 86 is formed so that the pipe-shaped rail 6 can be stably and surely inserted and fixed to the rail insertion hole 81, the rail insertion hole 81 to the rear wall 31 side of the spacer mounting base frame 28 can be provided. The offset structure is simplified, and the manufacturing cost can be kept low.

  Further, since the rail fixing female screw hole 82 is formed in the rail insertion fixing portion 29 on the rear wall 31 side of the spacer mounting base frame 28, the rail fixing bolt 83 can be attached and fastened without the vertical column 4 interfering. It can be done easily.

  Further, the outer peripheral wall of the upper half portion of the rail insertion fixing portion 29 forms an upper outer wall 87 having substantially the same curvature as that of the pipe-shaped rail 6, and the thickness of the upper outer wall 87 and the rail abutment wall 84 within the allowable strength. The outer peripheral wall of the lower half portion is formed thin and extends obliquely upward and outward from the upper corner portion of the rear wall 31 of the spacer mounting base frame 28 and penetrates the offset space 86 so that the center of the pipe-shaped rail 6 is the axial direction. A lower inclined outer wall 88 that has a predetermined thickness that allows a rail fixing female screw hole 82 to be drilled to form a tap having sufficient strength for screwing the rail fixing bolt 83 into the upper outer wall 87. Since the lower vertical outer wall 89 standing on the upper surface 85 of the spacer mounting base frame 28 and continuing to the other upper outer wall 87 is formed, the step between the outer peripheral surface of the pipe-shaped rail 6 and the upper outer wall 87 is kept low. Can be pulled Takes can be prevented.

  Further, the screwing strength of the rail fixing bolt 83 with respect to the rail fixing female screw hole 82 can be increased, and the pipe-shaped rail 6 can be pressed and fixed with the rail fixing bolt 83 in a direction advantageous in terms of strength.

  Furthermore, since the upper outer wall 87 has a curved shape, gravel, rainwater, snow, and other foreign matters are unlikely to accumulate on the pipe-like rail 6, and the smooth sliding of the door body M can be maintained for a long period.

  In this description, the embodiment in which the mounting bracket 27 is installed below the house entrance m is shown. However, for example, the pipe-shaped rail 6 is installed at the corresponding position instead of the suspension guide rail 7, and the pipe-shaped rail is installed.
