Description

  The present invention relates to a roof accessory fixing bracket used to fix a roof tile to a roof base material.

  When fixing the roof tiles to the base material of the roof, fixing the roof tiles only with wiping soil usually takes a long time to dry, and it is difficult to make the height of the roof tiles uniform. It is constructed with a purlin and a roof fitting fixture.

  Some of these roof fitting fixing brackets can be adjusted in height, and when used, the purlin can be fixed in a straight line even if the roof ridge is wavy up and down.

  The roof accessory fixing bracket capable of adjusting the height generally includes a first member for fixing a purlin and a second member for fixing to a base material. The first member has a U-shaped receiving part opened on the upper side, and the second member has a C-shaped leg part opened on the lower side, so that the height of the purlin can be adjusted. One member and the second member are connected.

  As a roof accessory fixing metal fitting capable of such height adjustment, a metal fitting (Patent Document 1) simply connecting the first member and the second member with a pin, or a fitting protrusion of the first member of the second member A metal fitting that simply fits into the fitting hole (Patent Document 2) has been proposed.

  However, the conventional roof accessory fixing bracket has the following problems. That is, the first member and the second member that are simply connected by a pin are easy to connect, but the load from the roof tile is concentrated on the pin, so that the strength and durability are poor. Moreover, although the thing which just fits the fitting convex part of a 1st member in the fitting hole of a 2nd member is easy to connect, there exists a possibility that a connection may be released by the load of a direction opposite to a fitting direction. Therefore, there is a problem that strength and durability against earthquakes and typhoons are inferior.

  On the other hand, what connects the 1st member and the 2nd member with a volt | bolt is excellent in intensity | strength and durability, but connection is troublesome.

Japanese Patent Laid-Open No. 11-172857 JP 2000-145038 A

  The problem to be solved by the present invention is to provide a roof accessory fixing metal fitting that can be height-adjusted, can be easily connected, and is excellent in strength and durability.

  In order to solve the above-mentioned problem, a first member having a receiving part for supporting a purlin and a supporting pillar part extending downward from the receiving part, a leg part fixed to a base material, and a supporting pillar part extending upward from the leg part The first and second members have pillar portions each having a substantially U-shaped cross section including opposing walls facing each other and a connecting wall connecting the opposite walls, and the first and second members. The opposing wall of one of the members is fitted between the opposing walls of the other member, and the one member is provided with a projecting piece extending from the U-shaped open side edge of the opposing wall. Provided is a roof accessory fixing bracket in which a plurality of openings for inserting the protruding pieces are provided at intervals in the vertical direction on the connecting wall of the member.

Such a roof accessory fixing bracket becomes more preferable when the following configuration is added.
1) A hole penetrating in the thickness direction of the protruding piece is provided in a protruding portion of the protruding piece from the opening of the connecting wall.
2) The protruding pieces are provided so as to form a pair on at least both sides.
3) The one member is provided with a guide piece that protrudes outward from the end of the connecting wall and bends to the opposite wall side, and the other member has an auxiliary wall that projects outward from the U-shaped open end of the opposite wall. A plurality of notches or openings for locking the guide pieces are provided in the auxiliary wall at intervals in the vertical direction.
4) A relief portion for avoiding interference with the base material is formed at the lower end of the connecting wall of the one member or the lower end of the connecting wall of the other member.

  Since the roof accessory fixing bracket of the present invention has a plurality of openings into which the projecting pieces are inserted at intervals in the vertical direction, the height of the purlin is adjusted stepwise by changing the openings into which the projecting pieces are inserted. be able to.

  Further, in this roof accessory fixing bracket, the opposing wall of one of the first and second members is fitted between the opposing walls of the other member, and the projecting piece of the one member is fitted to the other member. Since the structure is inserted into the opening of the connecting wall, the load from the roof tile can be distributed and supported by the opposing wall, connecting wall, and protruding piece, and the strength and durability are excellent.

  Furthermore, the protrusion of the protruding piece from the opening of the connecting wall provided with a hole penetrating in the thickness direction of the protruding piece can easily bend the protruding portion of the protruding piece from the opening. In addition, since a nail or the like can be inserted into the through hole, the connection reliability is high.

  Furthermore, since the protrusions provided so as to form a pair on at least both sides distribute and support the load from the roof tiles on both sides, the posture of the first member becomes more stable.

  Further, the one member is provided with a guide piece that protrudes outward from the end of the connecting wall and bends to the opposite wall side, and the guide piece is locked to a notch or an opening provided in the other member. Since the received piece receives the load by the roof tile at a position where the guide piece and the protruding piece are separated from each other, the strength and durability are further improved.

  Furthermore, what formed the escape part which avoids interference with a base material in the lower end of the connection wall of said one member or the lower end of the connection wall of said other member can be reliably fixed to a base material.

  The purpose of providing a roof fitting fixing bracket that can be adjusted in height, is easy to connect, and has excellent strength and durability has been realized with a minimum of members.

  FIG. 1 is a perspective view of the roof accessory fixing bracket of the first embodiment, and FIG. 2 is an exploded perspective view. The roof accessory fixing bracket includes a first member 10 and a second member 20.

  The first member 10 includes a receiving portion 11 that supports the purlin and a support column 12 that extends downward from the receiving portion 11.

  The receiving portion 11 has a U-shape with the upper side opened in FIG. 2, but may have other shapes that can receive and support purlins. The facing wall portions 11a of the receiving portion 11 are each provided with a through hole 11b through which a nail, a screw, or the like for fixing a purlin is passed.

  The support column 12 has a substantially U-shaped cross section including an opposing wall 13 and a connecting wall 14 that connect the opposing wall 13. In FIG. 2, the support column 12 is formed by bending a metal plate into a U shape, but may be formed by further bending the open end of the U shape inward as shown in FIG. 3, for example. If it does in this way, it will become difficult to deform | transform the support | pillar part 12, and an intensity | strength and durability will improve.

  The 1st member 10 has the protrusion 15 extended from the edge of the U-shaped open side of the opposing wall 13 so that it may become 1 pair (a figure is 2 pairs) at both sides.

  The second member 20 includes a leg portion 21 that is fixed to the base material, and a support column portion 22 that extends upward from the leg portion 21.

  The leg portion 21 has a square shape with the lower side opened in FIG. 2, but may have other shapes that can be fixed to the base material. Each of the wings 21a of the leg 21 is provided with a through hole 21b through which a base material fixing nail, a screw or the like is passed.

  The support column 22 has a substantially U-shaped cross section including an opposing wall 23 facing each other and a connecting wall 24 connecting the opposing wall 23.

  The facing wall 23 has a structure in which the facing wall 13 is fitted in such a manner that the U-shaped open sides of the column portion 12 and the column portion 22 face each other.

  The connecting wall 24 has an opening 25 into which the projecting piece 15 of the first member is inserted.

  The connecting wall 24 has a plurality of openings 25 (four pairs in the figure) with an interval in the vertical direction, and the arrangement interval is the same as the arrangement interval of the protrusions 15 in the vertical direction. As a result, the height of the purlin can be adjusted step by step for each arrangement interval in the vertical direction of the projecting piece 15 by changing the locking position of the projecting piece 15.

  The projecting piece 15 extends horizontally in FIG. 2, but may extend obliquely downward as shown in FIG. 4, for example. If it does in this way, it will become difficult to remove the protrusion 15 from the opening part 25 of the 2nd member by the weight of the roof tile which acts on the receiving part 11, and the reliability of connection with a 1st member and a 2nd member will increase.

  The projecting piece 15 has a structure that is inserted into the opening 25 as it is in FIG. 2, but may be a structure that is elastically deformed and inserted as shown in FIG. 5, for example. If it does in this way, after the protrusion 15 passes through the opening part 25, it will be elastically restored and it will become difficult to come out from the opening part 25, and the connection of a 1st member and a 2nd member will become stronger.

  The projecting piece 15 has a hole 15 a penetrating in the thickness direction of the projecting piece 15 at a protruding portion from the opening 25. This makes it easy to bend the projecting piece 15 in the vicinity of the through hole 15a, and allows a nail 30 or a pin to be inserted into the through hole 15a. The projecting piece 15 has only the through hole 15a in FIG. 2, but may further include, for example, a slit 15b as shown in FIG.

  The first member 10 has a guide piece 16 that protrudes outward from the end of the connecting wall 14 and bends toward the opposing wall 13. Although the guide piece 16 may be cut and raised as shown in FIG. 2, it may be formed by connecting another member.

  The guide pieces 16 are preferably provided so as to form a pair at least on both sides. If it does in this way, since the load by a roof tile is distributed and supported on both sides, the posture of the 1st member 10 becomes more stable. Further, a structure in which the guide piece 16 fits the opposing wall 23 is preferable. This is because the opposing wall 23 is also restrained from the outside by the guide piece 16, and the connection between the first member 10 and the second member 20 becomes stronger.

  The second member 20 has an auxiliary wall 26 projecting outward from the end of the opposite wall 23 on the U-shaped open side. The auxiliary wall 26 may be formed integrally with the opposing wall 23 as shown in FIG. 2, but may be formed by connecting another member.

  The auxiliary wall 26 has a plurality of cutouts 26a (three in the figure) spaced apart in the vertical direction for locking the guide piece 16. The notch 26a may be replaced with an opening 26b as shown in FIG. If it does in this way, the guide piece 16 will also be restrained from the outer side by the auxiliary wall 26, and the connection of the 1st member 10 and the 2nd member 20 will become stronger.

  Each of the connecting wall 14 and the connecting wall 24 has escape portions 14a and 24a that avoid interference with the base material at the lower ends thereof. In FIG. 2, the escape portion 14 a has a shape that gradually becomes deeper toward the center of the connection wall 14, but when the protrusion 15 is passed through the lowermost opening 25, the connection wall 14 and the connection wall 24 are the base. Other shapes that do not interfere with the material may be used.

If the roof accessory fixing bracket of the first embodiment is used, the following effects are obtained.
1) Even if the roof ridge is wavy up and down, the height of the ridge can be adjusted stepwise by changing the insertion position of the projecting piece 15, and the ridge can be fixed linearly.
2) Since the load from the roof tile is distributed and supported by the opposing wall 13, the connecting wall 14, the projecting piece 15, and the guide piece 26, it is excellent in strength and durability.
3) If the projecting piece 15 is bent in the vicinity of the through hole 15a, or if a nail 30 or the like is inserted into the through hole 15a, the first member 10 is affected even if a load in the direction opposite to the penetrating direction of the projecting piece 15 acts on the first member 10. And the connection between the second member 20 is not broken and the reliability of the connection is increased.
4) Since the projecting piece 15 receives and supports the load from the roof tiles on both sides, the posture of the first member 10 becomes more stable.
5) Since the projecting piece 15 and the guide piece 16 are separated from each other, even if a moment load is applied to the first member 10, the load is not easily concentrated on the projecting piece 15 or the guide piece 16 and is not easily broken.
6) Since the connecting walls 14 and 24 do not interfere with the base material, the roof accessory fixing bracket can be reliably fixed to the base material.

  The first member 10 and the second member 20 can be connected by simply locking the protruding piece 15 and the guide piece 16 to the opening 25 and the opening 26a, respectively, and further connecting the protruding piece 15 to the through hole 15a as required. It is only necessary to bend the vicinity or insert the nail 30 or the like into the through hole 15a. Therefore, connection with the 1st member 10 and the 2nd member 20 is easy, and efficient construction is possible.

  The first member 10 has a strut portion having the same structure as the strut portion 22 of the second member 20, and the second member 20 has a strut portion having the same structure as the strut portion 12 of the first member 10. The same effect can be obtained.
