  In the following, the present invention will be described in more detail with reference to the drawings. A is a carport, 1 is its column, 2 is a beam, 3 is a roof, 4 is between the free end of the roof 3 and the ground surface. A support column is provided which prevents the drooping of the roof 3 due to strong winds or drooping by snow by interposing and supporting the free end of the roof 3.

  The support strut 4 is configured to be adjustable in length, and the support hook side cylindrical fitting 20 disposed at the upper end of the support strut 4 is installed at the free end of the roof 3, in this example, the tip of the beam 2. These are detachably connected to each other by hooking and engaging the hook bracket 30 having the hook 31 disposed at the lower end with the hook receiver 42 of the embedded bracket 40 embedded on the ground surface. Are connected so that the free end of the roof 3 is supported between the free end of the roof 3 and the ground surface, and the free end support of the roof 3 is not required. When the wind and snow are not expected, the support column 4 is removed from the support bracket 10 and the embedded bracket 40, and the upper bracket 1a and the lower bracket 1b are installed on the column 1 arranged on one side of the roof 3. And these And additionally provided a support strut 4 in the strut 1 by supporting the serial cylindrical hook bracket 20 and the hook fitting 30 is intended to perform its housing.

  The roof side support metal fitting 10 has, for example, a metal metal fitting having an attachment base portion 11 that can be attached and fixed to the free end of the roof 3 and a support rod 14 of a predetermined length that is horizontally disposed below the attachment base portion 11. The mounting base portion 11 of the support fitting 10 is formed in a U shape that is fitted on the tip of the beam 2 and fastened and fixed with a bolt and nut, and a support rod 14 is formed in a circular cross section. The pair of opposed projecting pieces 13 projecting from the mounting base portion 11 are installed and installed, and the pair of opposed projecting pieces 13 of the present example hangs down from the bottom plate 12 of the U-shaped mounting base portion 11 and projects. It is assumed that the support rod 14 is arranged in the direction perpendicular to the lower end of the beam 2.

  Therefore, the support bracket 10 of this example is fitted with the U-shaped mounting base 11 from the lower side to the respective ends of the two beams 2 in the carport depth direction in this example, and the mounting base 11, In particular, a bolt is inserted from the side so as to pass through the beam 2 and a nut is screwed to the tip of the bolt, whereby the bolt and nut are fastened and fixed, and the lower side of the tip of each beam 2 is placed from the lower surface. The support rods 14 are arranged so as to be spaced apart downward and directed in a direction orthogonal to the beam 2.

  The support hook side cylindrical hook metal fitting 20 has a cylindrical shape with an outer diameter shorter than the length of the support rod 14 so as to be freely inserted into and fixed to the upper end hollow portion of the support post 4 having a square or rectangular cross section. The receiving groove 22 that opens upward at the upper end of the opposite position and the length of the receiving groove 22 that is continuous with the same length in the same direction of the circumference and that is substantially equal to the outer diameter of the support rod 14 and slightly wider than this. Similarly, for example, a metal fitting having a pair of opposed L-shaped hooking grooves 21 that form an inverted L shape with the horizontal groove 23. In this example, the length of the cylindrical hooking metal 20 in the horizontal groove 23 is the same as the length. , By arranging the receiving groove 22 at a position displaced by an angle of 1/8 circle from the center line in the width direction of the support groove 4 on the side opposite to the side where the lateral grooves are not disposed. Support by turning 1/8 circle There as being a freely hooking engagement to support rod 14 of the tool 10.

  That is, the cylindrical hook metal fitting 20 of this example is a pipe having a circular cross section having an outer diameter that can be fitted in or close to four or two places in the hollow portion of the support pillar 4 having a square or rectangular cross section. It is made of a metal circular pipe that is formed by cutting the L-shaped hooking groove 21 and the screw hole 24 for insertion and fixing, and the lower part is inserted into the upper end of the hollow part of the support column 4, The L-shaped catching groove 21 is positioned so as to protrude upward from the upper end edge of the support column 4 while being fixed in the upper and lower two positions on the front and rear surfaces by screws from the outside of the support column 4. It is.

  At this time, the L-shaped hooking groove 21 of the present example is configured such that the receiving groove 22 and the lateral groove 23 have the same groove width by matching the above-mentioned circular cross-sectional support rod 14 with the receiving groove 22 of the cylindrical hooking metal fitting 20. A vertical groove that opens upward at the opposite end of the circumferential direction at 180 degrees in the circumferential direction, that is, at the opposite position on the center line thereof, and the lateral groove 23 continues from the lower end of the receiving groove 22 in the circumferential direction, particularly in the same direction. This is a horizontal groove arranged horizontally in the present example, with a length of 1/8 circle, that is, an angle of about 45 degrees.

  The support rod 14 and the L-shaped hooking groove 21 of this example are made substantially equal by setting the outer diameter and the groove width of 6 to 7 mm, for example, and at this time, the groove widths of the receiving groove 22 and the lateral groove 23 are about 1 mm. In the following, for example, about 0.5 mm is made slightly wider than the outer diameter of the support rod 14, thereby allowing the support rod 14 to be smoothly received in the L-shaped hooking groove 21 and the support rod 14 and L-shape. The possibility of swinging with the hooking groove 21 is eliminated. The dimension of the L-shaped catching groove 21 that is wider than the outer diameter of the support rod 14 is not particularly limited in the receiving groove 22, but is approximately 1 mm or less in the lateral groove 23, for example, 0. It is particularly preferable to set the thickness to about 0.5 ± 0.2 mm on the basis of several mm, and if it exceeds this, the support rod 14 is loosely fitted into the L-shaped hooking groove 21, so that there is a possibility of swinging. If this occurs, the rotational movement of the support rod 14 may not be smoothly performed.

  The cylindrical hooking metal fitting 20 is fitted into the upper end hollow portion of the support column 4 so that the L-shaped hooking groove 21 protrudes upward, and a screw is screwed into the screw hole from the outside of the support column 4 to fix it. Thus, it is assumed that it is installed at the upper end of the support column 4.

  The support metal fitting 10 and the cylindrical hook metal fitting 20 configured as described above are arranged so that the pair of receiving grooves 22 opposed to the L-shaped hook groove 21 in the cylindrical hook metal fitting 20 are aligned with two positions in the longitudinal direction of the support rod 14 of the support metal fitting 10. When the bracket 20 is lifted, a single support rod 14 is received in the pair of opposed receiving grooves 22, and when the support rod 14 comes into contact with the lower end of the receiving groove 22, the cylindrical hooking bracket 20 is rotated by ¼ circle. By doing so, the support rod 14 may be slid and moved to the lateral groove 23 of the L-shaped catching groove 21 so that the support rod 14 is disposed at the tip of the opposed pair of lateral grooves 23. Then, the L-shaped hooking groove 21 of the cylindrical hooking metal member 20 is hooked and engaged, and the support column 4 is securely connected and supported to the free end of the roof 3, in this example, the beam 2. At this time, the connection support may be achieved by rotating the cylindrical hooking metal 20 by a quarter of a circle, and the rotation is such that the groove width of the L-shaped hooking groove 21 is substantially equal to the outer diameter of the support rod 14. The wide width prevents the support rod 14 from swinging in the L-shaped hook groove 21 without hindering smooth rotation, and the positional relationship between the support bracket 10 and the cylindrical hook bracket 20 is always constant. Therefore, the support column 4 supports the roof 3 securely and firmly, prevents the roof 3 from being turned, and reliably prevents the generation of metal noise caused by the swinging of the support metal fitting 10 and the cylindrical hook metal fitting 20. Can do. In this example, since the horizontal groove 23 of the L-shaped catching groove 21 is a horizontal groove, for example, when the horizontal groove 23 is an upwardly inclined horizontal groove or a downwardly inclined horizontal groove, the end of the beam 2 due to the turning of the roof 3 is used. As a result of the vertical movement, the possibility that the support rod 14 swings in the longitudinal direction in the L-shaped hooking groove 21 to generate metal noise when returning to its home position can be eliminated.

  The support column 4 is interposed by the support bracket 10 and the cylindrical hook bracket 20 by hooking and engaging the support column 4 to the beam 2 to connect to the free end of the roof 3. The hook 31 of the hook metal member 30 disposed at the lower end may be hooked and engaged with the hook receiver 42 of the embedded metal fitting 40 and connected to the ground surface. At this time, the hook engagement of the hook 31 with the hook receiver 42 is the beam 2. In general, the support strut 4 connected to the support rod 14 is rotated to the side surface of the carport A with the support rod 14 as a fulcrum, and the hook engagement of the L-shaped hook groove 21 with the support rod 14 is as follows. , It is necessary to perform the connection so that the support column 4 can be rotated. For this reason, in this example, the support rod 14 of the support fitting 10 is arranged along the longitudinal direction of the roof free end so as to be orthogonal to the tip of the beam 2, while the cylindrical hook fitting 20 has its L-shaped hook groove. The receiving groove 22 is opened at a position displaced by ¼ circle with respect to this, and is installed on the support column 4 so that the support column 4 faces the front by the rotation of the cylindrical hooking metal fitting 20. . The support support 4 of this example has a rectangular or rectangular cross section, so that the receiving groove 22 of the L-shaped hooking groove 21 is arranged between the front and the side, in the case of a square cross section, diagonally and with a lateral groove 23. Are arranged so as to form a groove toward the front and the back, the hook 31 is arranged so as to project the locking piece toward the front side of the support column 4, and the hook receiver 42 is further connected to the carport A. The embedded metal fitting 40 is embedded and installed on the ground surface so as to be arranged in the depth direction on the side surface.

  In the figure, reference numeral 43 denotes an anchor of the embedded metal fitting 40, and 44 denotes a support post 4 that is removed when it is not needed. An openable and rotative cover 45 installed on the embedded metal fitting 40 so as to prevent the heel from being caught and to close the box 41 when the support column 4 is interposed. Opening and closing links are shown, which are supported so that the rotating cover 44 can be pivotally opened and closed on the upper surface of the box 41 and the vicinity of the ground surface by pivotally supporting the other end of the rotating cover 44.

  The example shown in the figure is as described above. However, the support rod of the support bracket should be installed at the free end of the roof at the end of the roof side frame, and the support rod of the support bracket should protrude horizontally or inclined in front of the free end of the roof. The L-shaped hook groove is formed by opening the receiving groove in an upward V-shape to form an L-shaped hook groove, and the lateral groove is inclined upward or downward to form an L-shaped hook groove. Accordingly, a cantilever carport, a roof, etc. can be used in the practice of the present invention, including forming a support rod fitting portion at the tip of the lateral groove to prevent the support rod from swinging as much as possible. , Support struts, support brackets, their mounting bases, support rods, cylindrical hook brackets, their specific materials such as L-shaped hook grooves, receiving grooves, transverse grooves, shapes, structures, relations, additions to these, etc. Various forms can be used as long as they do not contradict the gist of the invention. .
