Registered Utility Model No. 3164020

  The metal fitting of Patent Document 1 is well received because it is easy to fix without dropping mounting bolts during the fixing operation, and a strong fixing state can be obtained while having a simple configuration.

  However, in the fixed state of the metal fitting, the lower end of the sandwiching piece is in contact with the upper surface of the folded plate roof and the upper end of the sandwiching piece is flattened as described above. It can be fixed, but it cannot be fixed properly for folded-plate roofs that are slightly different in size.

  In view of the above, the main object of the present invention is to make it possible to fix even a roof having a different mountain size.

  The means for that purpose is a roof top structure support bracket that is fixed on a roof having a recess recessed left and right in the left and right direction below the top surface of the mountain portion protruding upward, and supports the roof top structure. A fixing member that has a support portion for supporting the roof structure on the upper surface and is placed on the top surface of the mountain portion, and a pair of left and right clamping members that are held on the left and right sides of the fixing member And a fastening shaft portion for holding the intermediate portion in the vertical direction of the fixing member and the holding member to couple the fixing member and the holding member and tightening the holding member in the direction of the fixing member. An engagement structure that allows relative rotation in the vertical direction and the horizontal direction to allow relative rotation is formed between the sandwiching member, and the roof of the roof is formed by tightening the fastening shaft portion at the lower part of the sandwiching member. On the roof where clamping pieces that press against the recess are formed It is a creation support bracket.

  In this configuration, the engagement structure between the fixing member and the holding member and the fastening shaft portion that couples the fixing member and the holding member allow the left and right holding members to rotate with respect to the fixing member. In the engaging structure portion, the clamping member is movable in the vertical direction and the horizontal direction with respect to the fixed member. Between the clamping member and the fastening shaft portion, the clamping member is disposed on the fastening shaft portion with the axis of the fastening shaft portion. Can rotate in the direction. For this reason, even if it has a fastening shaft part, the clamping member can be rotated within a certain range in the direction of opening and closing the lower part of the clamping member on both the left and right sides of the fixing member. To fix the structural support bracket on the roof to the roof, open the lower part of the clamping member to the left and right, place it on the top of the roof and place the fixing member on the top surface, and tighten it with the fastening shaft Do.

  In the state where the structure on the roof is fixed, the clamping piece of the clamping member is pressed against the concave portion of the roof, and is fixed in a retaining state. Since the sandwiching piece is configured to press contact with the recess, an appropriate press-contact state and sandwiching state can be obtained even if the angle of the sandwiching member is not constant.

  The upper surface of the fixing member supports the roof structure. Since the upper surface of the fixing member is constant and flat regardless of the angle of the holding member, the structure on the roof can be reliably supported.

  According to this invention, since it can fix appropriately also with respect to the roof from which the magnitude | size of a mountain part differs, the fixation object can be expanded and the convenience can be improved.

FIG. 1 is a front view of a use state of a roof structure support bracket 11 (hereinafter referred to as “support bracket”) for mounting a roof structure on a roof 51, and FIG. 2 is a perspective view of the support bracket 11. FIG. 3 and FIG. 3 are exploded perspective views thereof. In FIG. 1, illustration of a tight frame for fixing the roof 51, a base material for supporting the tight frame, and the structure on the roof is omitted for convenience.

  As shown by the phantom lines in FIG. 1, the support metal fitting 11 of the present invention is configured to be able to be fixed to the roof 51 having different shape dimensions.

First, the shape of the roof 51 will be briefly described.
The roof 51 is made of a folded plate, and a plurality of peak portions 52 protruding upward are spaced apart in the left-right direction. The mountain portion has a flat top surface 53 and a skirt portion 54 that extends from the head having the top surface 53 in a laterally diverging manner. On both the left and right sides below the top surface 53, there are recesses 55 that are recessed in the left-right direction. The recess 55 has a triangular shape when viewed from the front, and the bottom portion 54 is continuously formed below the recess 55. For this reason, the peak part 52 is a shape which has the constriction part which consists of the said recess 55 below the head as a whole.

  The size and shape of each part of the peak portion 52, specifically, the shape of the top surface 53, the length (width) of the top surface 53 in the left-right direction, the height of the recess 55 with respect to the top surface 53, and the left and right recesses 55 There is a difference in the interval between the folded plates.

Next, the support metal fitting 11 will be described.
The support 11 is fixed to the mountain portion 52 of the roof 51 to support the structure on the roof, and the fixing member 21 placed on the top surface 53 of the mountain portion 52 and the fixing member 21 on the left and right sides. A pair of left and right clamping members 21 held so as to be sandwiched from both sides, and a fastening shaft portion 41 that couples the fixing member 21 and the clamping member 31 are provided.

  The fastening shaft portion 41 includes a fastening bottle 42 having a length penetrating the whole of the one fixing member 21 and the two sandwiching members 31 in the left-right direction, and a fastening nut 43 screwed into a male screw of the fastening bolt 42. It consists of The fastening bolt 41 includes a washer 44 and a spring washer 45 in addition to the fastening nut 43.

  The fixing member 21 is formed by pressing a metal plate, and has a hat-shaped longitudinal section. That is, the fixing member 21 has a flat support portion 22 for supporting the roof structure on the upper surface, and has leg portions 23 extending downward from both left and right sides of the support portion 22. The lower end has a shape having a ground contact portion 24 that extends outward in the left-right direction and contacts the top surface of the peak portion 52.

  The length of the support portion 22, the leg portion 23, and the ground contact portion 24 in the direction corresponding to the gradient direction of the roof 51 (hereinafter referred to as “front-rear direction”) is the same, and is set longer than the height of the fixing member 21. Yes.

  The support part 22 has a through hole 22a at the center (center in the front-rear direction and the left-right direction). The through hole 22a is for holding the fixing bolt 15 for fixing the roof structure, and the fixing bolt 15 is inserted and held from below the support portion 22. In order to make the held fixing bolt 15 non-rotatable, the width (inner) in the left and right direction of the lower surface of the support portion 22 is set to a length corresponding to the insertion length connecting the planes of the head 15a of the fixing bolt 15 to each other. Is set.

  Engagement holes 25 for detachably engaging the clamping member 31 are provided at the upper end corner of the fixing member 21, that is, both the left and right ends of the support 22 and the upper end of the leg 23. The engagement hole 25 is a part of an engagement structure that engages the fixing member 21 and the clamping member 31. The engagement hole 25 is formed by cutting out a range of a predetermined height of the upper end portion of the leg portion 23 into a substantially square shape by the thickness of the leg portion 23. At the lower end position of the engagement hole 25, there is a cut groove 25a that cuts inward in the front-rear direction.

  The engagement holes 25 having such a shape are formed on both side portions of the fixing member 21 in the front-rear direction with a space therebetween.

  The leg portion 23 includes a circular insertion hole 26 through which the fastening bolt 42 is inserted at an intermediate portion in the vertical direction and in the intermediate position in the front-rear direction. The size of the insertion hole 26 is a size corresponding to the thickness of the fastening bottle 42.

  The grounding portion 24 has an area that is appropriately wide so that the fixing member 21 can be stably placed.

  The clamping member 31 is held on both the left and right sides of the fixing member 21 so as to be relatively rotatable in the direction of opening and closing the lower portion, and is formed by pressing a metal plate in the same manner as the fixing member 21. The two clamping members 31 arranged on the left and right have the same shape. The length in the front-rear direction of the clamping member 31 is the same as that of the fixing member 21.

  A clamping piece 32 that is pressed against the recess 55 of the roof 51 by tightening with the fastening shaft portion 41 is formed in the lower part of the clamping member 31. The sandwiching piece 32 is formed to be bent so as to form one corner of a triangular shape in front view so as to fit into the recess 55.

  A connecting piece 33 extending upward when the holding piece 32 is pressed against the recess 55 of the roof 51 so as to be prevented from coming off is continuously provided on the holding piece 32. Includes a gap holding piece 34 that extends toward the fixing member 21 and is spaced from the fixing member 21 at an appropriate interval. The connecting piece 34 is substantially formed in a flat plate shape, and has an insertion hole 36 through which the fastening bolt 42 is inserted at an intermediate portion in the vertical direction and in an intermediate position in the front-rear direction. An abutting portion 35 that abuts against the fixing member 21 is formed at the tip of the interval holding piece 34. The length of the interval holding piece 34 is such that the connecting piece 34 is vertical or substantially vertical when fixing is applied to the peak portion 52 of the roof 51 to be fixed and the interval between the concave portions 55 is the narrowest. Length is set.

  The insertion hole 36 of the connecting piece 33 is substantially circular having a size corresponding to the thickness of the fastening bolt 42, and has a rounded corner 36a at the corner of the fixing member 21 as shown in FIG. The corner round portion 36 a is a portion for allowing the clamping member 31 to relatively rotate in the axial direction of the fastening bolt 42. That is, the corner radius portion 36 a contributes to permitting the relative rotation of the clamping member 31 with respect to the fixing member 21. Since the rectangular round portion 36a has a circular cross-sectional shape, it can maintain a stable interrelationship regardless of the angle with the clamping member 31. A chamfered portion may be formed instead of the corner rounded portion 36a.

  Around the insertion hole 36, specifically, above, a convex anti-rotation portion 33 a that makes contact with the hexagonal head portion 42 a of the fastening bolt 42 to prevent rotation is formed by cutting and raising.

  The connecting piece 33, the sandwiching piece 32, and a portion between them have an integral rib 33b that is bulged for reinforcement. The rib 33b is formed in an appropriate shape. In addition to the ribs 33b, the connecting piece 33 is provided with folded pieces 33c that bend in a direction opposite to the fixing member 21 at both ends in the front-rear direction in order to improve strength.

  An engagement piece 37 inserted and held in the engagement hole 25 of the fixing member 21 is provided at a position corresponding to the engagement hole 25 of the fixing member 21 at the tip of the interval holding piece 34. The engagement piece 37 is connected to the engagement piece main body 38 having a width that can be inserted into the engagement hole 25, and one end in the width direction of the distal end edge of the engagement piece main body 38. It has the retaining piece 39 which enters 25a.

  At the base of the engagement piece main body 38, there is a step 38a that is thicker than the support 22 of the fixing member 21, and a horizontal portion 38b and an inclined portion 38c are connected to the tip of the step 38a. The length of the horizontal portion 38b is a length that allows the engagement piece 37 to be relatively displaced in the left-right direction within the engagement hole 25, as shown in FIG. The retaining piece 39 is formed at the tip of the inclined portion 38c.

  The height of the engagement hole 25 is the thickness of the horizontal portion 38b of the engagement piece 27 so that the engagement piece 37 can be relatively displaced in the left-right direction in the engagement hole 25 and also in the vertical direction. It is set higher (see FIG. 5).

  The abutting portion 35 is suspended from a portion between the engagement pieces 37 at the tip of the interval holding piece 34. The contact portion 35 has a plate shape parallel to the connecting piece 33.

  Since the engagement hole 25 has the cut groove 25 a and the engagement piece 37 has the retaining piece 39, even if the engagement piece 37 is inserted into the engagement hole 25, it cannot be inserted from above. For this reason, when the clamping member 31 is engaged with the fixing member 21, as shown in FIG. 6, the lower part of the clamping member 31 is inclined toward the fixing member 21, and then the engagement piece 37 is inserted into the engagement hole 25. Insert. When the retaining piece 39 is inserted and passes through the cut groove 25a, the clamping member 31 can be rotated in a posture aligned with the side surface of the fixing member 21, and can be engaged.

  The support metal fitting 11 having such a configuration is assembled to the fixing member 21 with the clamping member 31 and the fixing bolt 15 and is carried into the site in an integrated state by the fastening shaft portion 41, and used as follows.

First, the fastening shaft part 41 is loosened so that the lower part of the clamping member 31 is opened.
As described above, the engagement piece 37 is allowed to move in the vertical direction and the horizontal direction within the engagement hole 25, and the corner round portion 36a is formed at the corner of the insertion hole 36 of the connection piece 33 on the fixing member 21 side. Therefore, the clamping member 31 rotates relative to the fixing member 21 while being supported by the fastening bolt 42 in a state where the upper end portion of the abutting portion 35 is in contact with or close to both the left and right side surfaces of the fixing member 21. Is possible.

  Since the engagement structure between the fixing member 21 and the clamping member 31 has the retaining piece 39 and the cut groove 25a, even if the clamping member 31 is opened, it is greatly rattled as long as it is held by the fastening shaft portion 41. It will not happen, and it will not be separated unexpectedly. Similarly, during transportation, rattling and unforeseen separation can be prevented, so on-site work can be carried out smoothly.

  The fixing bolt 15 is inserted and held from below the fixing member 21. However, since the fastening bolt 42 exists below the fixing bolt 15, the fixing bolt 15 does not drop off unexpectedly.

Next, the lower part of the clamping member 31 is opened and placed on the mountain part 52 of the roof 51.
The grounding portion 24 of the fixing member 21 comes into surface contact with the top surface 53 of the peak portion 52, and the clamping piece 32 of the clamping member 31 can come into contact with the recess 55 of the peak portion 52 from the left-right direction. When the fastening nut 43 of the fastening shaft portion 41 is tightened in this state, the fixing to the roof 51 is completed. That is, when clamping is performed, the clamping member 31 moves the clamping piece 32 into contact with the recess 55 while moving to the fixing member 21 side. At this time, if the abutting portion 35 of the clamping member 31 is not in contact with the fixing member 21, the clamping member 31 is rotated on the fastening bolt 42 to change the angle by further tightening, and the abutting portion 35 is changed to the fixing member 21. When in contact, a tightened state is obtained. The rotation of the clamping member 31 is displaced so as to lift the clamping piece 32 upward. Since the insertion hole 36 of the clamping member 31 that is in contact with the fastening bolt 42 is provided with the corner rounded portion 36a, the clamping member 31 is smoothly rotated, and the relative relationship with the fastening bolt 42 is obtained at any angle. Is highly stable.

  In the clamped state, the support fitting 11 is in a state of holding the head portion of the mountain portion 52 and is in a state of being prevented from coming off, and the fixing member 21 is stabilized on the top surface 53. FIG. 7 is a sectional view in a fixed state with respect to the roof 51 in which the interval between the recesses 55 of the mountain portion 52 is narrow, and FIG. 8 is a roof 51 in which the interval between the recesses 55 is wider than in the case of the roof 51 in FIG. It is sectional drawing of the fixed state with respect to. As shown in these drawings, a stable and strong fixed state can be obtained in any case even though the support bracket 11 is the same.

  Thereafter, the roof structure is fixed by using the fixing bolt 15 held by the fixing member 21.

  Thus, in order to fix the support metal fitting 11 to the roof 51, it is only necessary to loosen the fastening shaft portion 41 and place it on the mountain portion 52, and then tighten the fastening shaft portion 41. Therefore, the operation is very simple. In the fixing operation, the fixing bolt 15 and the clamping member 31 are not separated, so that the operation is not complicated and can be performed very smoothly.

  In addition, the clamping member 31 having the clamping piece 32 rotates on the outer side in the left-right direction of the fixing member 21, so that the vertical direction relative to the rotation amount is higher than that in the case where the clamping member 31 rotates about the intermediate position in the left-right direction of the fixing member 21. The amount of movement can be reduced. In other words, the entering angle of the holding piece 32 that moves toward the recess 55 with the rotation of the holding member 31 becomes loose. For this reason, the range of the height of the recess 55 and the position in the left-right direction that enables proper pressing of the clamping piece 32 is expanded. As a result, the support fitting 11 can be fixed also to the roof 51 having the ridges 52 in which the height of the recess 55 and the position in the left-right direction are different.

  Moreover, in the fixed state, the flat support portion 22 of the fixing member 21 supports the structure on the roof regardless of the angle of the clamping member 31, so that the structure on the roof can be supported stably. In addition, the fixed state is obtained by pressing so that the holding piece 32 enters the recess 55, so that a desired fixed state is obtained regardless of the angle of the holding member 31.

  Therefore, appropriate fixing can be performed even on the roof 51 having the mountain portions 52 having different sizes. For this reason, the fixed object which can use one support metal fitting 11 expands, and the convenience improves.

  Further, the support metal fitting 11 is mainly composed of three types of members, and the pair of right and left clamping members 31 have the same shape. Therefore, the configuration is simple and the number of parts is small, so that it can be manufactured at low cost.

  Such an effect is that the size of the portion that holds the head portion 15a of the fixing bolt 15 is set to a size capable of preventing rotation, and the head portion 42a of the fastening bolt 42 is attached to the connecting piece 33 of the clamping member 31. This is also obtained by providing the anti-rotation portion 33a for preventing the rotation, thereby eliminating the need for using a square bolt for the fixing bolt 15 and the fastening bolt 42.

  Hereinafter, other examples will be described. In this description, parts that are the same as or equivalent to those in the previous configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  FIG. 9 is a front view (FIG. 9A) and a side view (FIG. 9B) of a clamping member 31 according to another example. In this clamping member 31, the rotation preventing portion 33 a of the connecting piece 33 is provided not only above the insertion hole 36 but also below. The lower detent portion 33d is formed by cutting and raising as in the above example. On the other hand, the upper anti-rotation part 33e is formed to bulge out by punching. In the illustrated example, an example in which an ellipse is bulged is shown, but a point shape may be used.

  In this way, when the upper and lower convex detents 33d and 33e are provided, the inclination of the washer 44 provided on the fastening bolt 42 can be suppressed when the fastening shaft 41 is occupied, unlike the case where only the one is provided. .

  Further, the reinforcing rib 33b formed on the connecting piece 33 and the sandwiching piece 32 has a bulging portion wider than the shape of the rib 33b and a more complicated shape. If the desired strength is obtained in this way, the folded piece 33c can be omitted.

In correspondence between the configuration of the present invention and the configuration of the one aspect,
The engagement structure of the present invention corresponds to the engagement hole 25 and the engagement piece 37,
Similarly,
The upper end portion of the fixing member corresponds to the support portion 22,
The present invention is not limited to the above-described configuration, and other configurations can be employed.

  For example, the support fitting 11 does not have to fix a roof structure with bolts. That is, the support part 22 of the fixing member 21 may hold a part other than the fixing bolt 15 or may be provided with a part only to be locked.

  In addition, the fastening bolt 42 is not a structure that penetrates the entire support fitting 11 in the left-right direction, but can also constitute two fastening bolts that extend from the left and right sides of the fixing member 21 outward in the left-right direction.

  The abutting portion of the clamping member can be formed in a circular arc shape in the longitudinal section instead of a plate shape.
