Description

  The present invention relates to a roof tile support bracket installed along a roof ridge, in order to support and fix a roof tile beam that supports the same roof tile when the roof tile is provided along the roof ridge. The present invention relates to a ridge tile beam support metal fitting that can stably support a ridge tile beam even if it is installed in the inclined ridge when it has an inclined ridge such as a ridge roof or a dormitory roof.

  A roof tile is a roof tile built along a roof tower, and is constructed by stacking tile roof tiles and roof tiles. Recently, the collapse of roof tiles has become a problem as one of the earthquake damages, and among them, the collapse of ridge tiles has become a problem. In conventional houses, the ridge tiles were fixed with clay or plaster, but it was difficult to prevent the ridge tiles from collapsing due to a large-scale earthquake.

  Therefore, a structure is adopted in which a ridge tile beam is installed along the ridge using metal fittings, and the entire ridge tile is fixed by this ridge tile beam. The ridge roof beam support bracket for erection of such a ridge roof beam is made of steel plate, and is provided with a leg-shaped leg part, a column part standing from the leg part, and an upper part of the pillar part. And a beam support portion having a side U-shape with an open side.

Using such a ridge tile beam support bracket, the ridge tile beam is installed in parallel with the ridge line of the ridge along the roof ridge of the house. Scatter the roof tiles on both sides of the ridge, stack one or more roof tiles along the ridge, and fix it to the ridge roof tiles with metal wires. Furthermore, a tile roof tile, which is a type of round tile, is placed on top of the roof tile so as to cover the ridge tile beam, and fixed to the ridge tile beam to complete the ridge tile. Note that clay such as clay or plaster may be filled in advance so as to fill a gap with the roof tile below the pot roof tile.
When building a roof tile in this way, the height from the ridge portion of the roof base plate to the round roof tile varies depending on each house depending on the number of tile roof tiles to be stacked. In addition, the ridge portion of the field plate may not be a constant height, and a slight difference in height may occur.

  As a means for adjusting the height and laying the building tile beam at a certain height, as described in, for example, Japanese Patent Application Laid-Open No. 2000-145038 and Japanese Patent Application Laid-Open No. 2004-225323, Are separated into separate members. In such a ridge tile beam support bracket, a plurality of slits extending in the width direction at a certain height interval are provided on the side wall of the columnar portion erected from the leg portion of the lower member, and from the beam support portion of the upper member. A plurality of protrusions extending in the width direction at the same height interval as the slit are provided on the suspended columnar portion, and when the columnar portions of the upper and lower members are fitted to each other, the protrusion is inserted into the slit and fixed. Since a plurality of slits and protrusions are provided at a constant height interval, the height of the ridge tile beam support bracket, that is, from the leg to the beam, is selected by selecting the slit and protrusion to be fitted. The height to the support can be varied and adjusted.

  In the ridge tile beam support bracket having such a height adjustment function, because it is a structure in which the slit and protrusion extending in the width direction respectively provided on the side surfaces of the columnar part of the lower and upper members are only fitted from one side, Once inserted, the slits and protrusions are easily removed. For this reason, when attaching these ridge tile beam support brackets to an inclined ridge on the roof of a parlor ridge or in a main building, it is necessary to select the direction of the ridge tile beam support brackets and attach the ridge tile beam support brackets in such a direction that the projections do not come out from the slits. .

  However, in ordinary house building work, roofing work is ordered as a subcontract from the main contractor. Under these conditions, the time that can be spent on roofing work is limited, and roofing work is inevitably performed with an emphasis on efficiency. Therefore, there is no room for selecting the mounting direction of the ridge tile beam support brackets one by one, and the ridge tile beam support brackets are often mounted in a direction in which the slits and protrusions can be easily removed.

  Therefore, as described in Japanese Patent Application Laid-Open No. 2006-219928, when the protrusion is inserted into the slit so that the slit and the protrusion do not come out from any direction by joining the columnar portions of the lower and upper members from any direction, A ridge tile beam support bracket having a stopper for preventing the protrusion from moving in the longitudinal direction has been proposed. For example, a recess in which a protrusion can be fitted one step down is provided in the slit.

  However, if the projections can be fitted into the recesses in the slits, there will be a margin in the slits between the projections and the slits. As a result, in a state where the columnar portions of the lower and upper members are joined together, vertical shaking occurs between the lower and upper members, which becomes an unstable element.

  In view of the problems in the conventional building tile beam support bracket divided into two upper and lower members as described above, the present invention ensures that the upper and lower two members are prevented from coming off during assembly, and that the operation is simple during the assembly work. An object of the present invention is to provide a ridge tile beam support metal fitting that can eliminate up and down shakiness.

In the present invention, in order to achieve the above object, the protrusion 34 is inserted into the slit 13 of the lower member strut portion 10 of the lower member 1 to which the protrusion 34 of the upper member strut portion 30 of the upper member 2 is engaged. A vertical movement restricting portion 18 for restricting the vertical movement of the protrusion 34 is provided outside the retaining portion 15 for preventing the opening 14 and the protrusion 34 from coming off from the insertion opening 14. The protrusion 34 is provided at a position that is lower than the height D of the height h .

That is, the ridge tile beam support metal fitting according to the present invention supports the ridge tile beam that supports the ridge tiles that are spliced along the roof ridge, joined to the lower member 1 fixed to the position of the roof ridge. The lower member 1 includes a leg portion 20 fixed to the base plate across both sides of the roof ridge portion, and a columnar lower member strut portion 10 erected from the leg portion 20. And the upper member 2 includes a beam support portion 40 that supports the ridge tile beam, and a columnar upper member support portion 30 that is suspended from the beam support portion 40, and the lower member support portion 30 of the lower member 1 10 and the upper member strut 30 of the upper member 2 are provided with slits 13 and protrusions 34 that engage with each other when the lower member strut 10 and the upper member strut 30 are joined together. The slit 13 includes an insertion port 14 into which the projection 34 is inserted, a recess 15 that is one step lower in the back of the insertion port 14, and a slit-like vertical movement restricting portion 18 that is provided in the back of the recess 15. Yes, and the upper and lower regulating portion 18 is provided below the insertion port 14 only step D position, the step D is equal to or greater than the height h of the projection 34.

In such a ridge tile beam support metal fitting according to the present invention, when the upper member 2 is attached to the lower member 1, the upper member strut portion 30 of the upper member 2 is fitted into the lower member strut portion 10 of the lower member 1. At this time, the protrusion 34 of the upper member strut portion 30 of the upper member 2 is engaged with the slit 13 of the lower member strut portion 10 of the lower member 1. The protrusion 34 of the upper member support column 30 is first inserted into the slit 13 from the insertion port 14, and inserted into the recess 15 at the back thereof to be prevented from coming off. Further, by inserting the projection 34 into the vertical movement restricting portion 18 in the slit 13, the vertical movement of the lower member strut portion 10 of the lower member 1 and the upper member strut portion 30 of the upper member 2 is restricted.

More specifically, the protrusion 34 is first inserted into the slit 13 from the insertion port 14 and then inserted into the recessed portion 15 that is one step lower in the depth. Here, by pushing the upper member strut portion 30 downward with respect to the lower member strut portion 10, the protrusion 34 is fitted into the recess 15, and the protrusion 34 is prevented from coming out of the insertion port 14. From this state, the upper member strut portion 30 is pushed into the lower member strut portion 10, and the protrusion 34 is inserted further into the slit 13, so that the protrusion 34 is provided at the back of the recess 15 of the slit 13. It is inserted into the up-and-down restricting portion 18 composed of a slit-like portion having a narrow width. Thereby, the vertical movement of the upper member 2 with respect to the lower member 1 is regulated.

  As described above, in the ridge tile beam support metal fitting according to the present invention, when the upper member 2 is attached to the lower member 1, the protrusion 34 of the upper member column portion 30 of the upper member 2 is inserted into the slit 13 of the lower member column portion 10 of the lower member 1. During the work, the upper member column 30 of the upper member 2 is prevented from coming off from the lower member column 10 of the lower member 1 by a simple insertion operation. In addition, it is possible to easily prevent the backlash in the latter vertical direction with respect to the former. Thereby, it is possible to easily realize an assembled state in which the lower member 1 and the upper member 2 are not pulled out or rattled.

It is a perspective view in the state where the lower member and upper member which show the tile beam support metal fitting by the 1st example of the present invention were separated. It is a perspective view of the state in the middle of attaching the upper member to the lower member which shows the tile beam support metal fitting by the Example.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

FIG. 1 is a view separately showing components of a ridge tile beam support fitting according to an embodiment of the present invention. As shown in FIG. 1, the ridge tile beam support bracket includes a lower member 1 and an upper member 2. For example, both are made by punching and bending a metal plate such as a steel plate with a press.
The lower member 1 has a pair of plate-like leg portions 20, 20 that are spread out on both sides in a front “C” shape, and the leg portions 20, 20 are provided with a plurality of nail holes 21. . The inclination angle of the legs 20 and 20 is usually about 30 °, but this is set in accordance with the roof slope. The bending angle may be forcibly changed by hand.

From the highest part of the legs 20, 20, the lower member support column 10 having a plane “U” shape is erected. Side walls 11 on both sides of the lower member support column 10 are integral with the leg portion 20, and reinforcing ribs 22, 22 for increasing rigidity are provided at bent portions thereof.
The side walls 11 on both sides of the lower member support column 10 are provided with a plurality of slits 13 at regular intervals in the vertical direction. Although the number of the slits 13 is three in the illustrated example, it can be an arbitrary number depending on the purpose of use. A recess 13 ′ is provided at the top of the side wall 11 on both sides of the lower member support column 10 instead of the window-shaped slit 13.

The slit 13 is formed on the opposite side of the front side where the side walls 11, 11 of the lower member support column 10 are connected by the front wall 12, that is, on the back side where the plane “U” -shaped “U” is opened. have. This slit 13 is deepened one step downward on the back side of the insertion port 14 and forms a recess 15. The depth of the concave portion 15 , that is, the step D (see FIG. 4A, the same applies hereinafter) with respect to the insertion port 14 is set to be equal to or greater than the thickness of the metal plate constituting the upper member 2 described later. Further, on the back of the recess 15 of the slit 13, that is, on the side opposite to the back side of the lower member support column 10 provided with the insertion port 14, a slit-like vertical regulating portion 18 whose vertical width becomes narrower toward the front side. Is cut. The vertical restricting portion 18 is provided on the extension along the bottom of the concave portion 15, and therefore the vertical restricting portion 18 is at a position lower than the insertion port 14 by the step D. The vertical width of the vertical regulating portion 18 is slightly larger than the thickness of a metal plate constituting the upper member 2 described later, that is, slightly larger than the thickness of the metal plate. The depth, that is, the front and rear dimensions, may be about half or less of the recess 15.

Holes 17 are provided in front of the slits 13 in the side walls 11 on both sides of the lower member support column 10. As shown in FIG. 1, one hole 17 may be provided, but a plurality of holes 17 may be provided at the same interval as the slit 13.
Further, in the illustrated example, a window-like rectangular opening 16 is also provided on the front wall 12 of the lower member support column 10. The vertical distance of the opening 16 is the same as that of the slit 13, and the vertical height of the opening 16 is the same as that of the recess 15 of the slit 13. A concave portion 16 ′ is provided at the top of the front wall 12 of the lower member support column 10 instead of the window-shaped opening 16.

  On the other hand, the upper member 2 has a front horizontal U-shaped beam support portion 40 whose top is opened at the uppermost end, and a columnar upper member support column portion 30 is integrally connected downward from the center of the beam support portion 40 to hang down. doing. The planar shape of the upper member support column 30 is a planar U shape with the back surface opened. Reinforcing ribs 41, 41, 42, and 42 are formed at the bending angle of the beam support portion 40 and the bending angle between the beam support portion 40 and the upper member support column portion 30. In addition, nail holes 43 for fixing the ridge tile beams are formed in both side walls of the ridge support portion 40.

  The front outer width dimension and the side outer width dimension of the upper member strut 30 are slightly smaller than the front inner width dimension and the side inner width dimension of the lower member strut section 10 of the lower member 1. The lower member 1 can be inserted into the lower member strut 10 from the opened rear. Further, the height of the upper member support column 30 is slightly higher than that of the lower member support 10 of the lower member 1.

  On the side wall 31 of the upper member support 30 of the upper member 2, protrusions 34 formed by cutting out a part of the side wall 31 protrude vertically. The upper and lower intervals of the protrusions 34 are the same intervals as the slits 13 and the recesses 13 ′ provided in the lower member support 10 of the lower member 1. In the illustrated embodiment, the two protrusions 34 are provided below the upper member support column 30. However, three or more protrusions 34 or the same number four as the slits 13 and the recesses 13 'may be provided at the same interval.

The tip of the protrusion 34 is wider than the base, and both sides of the tip protrude outward from the base. The width of the base of the projection 34 is slightly narrower than the recess 15 at the back of the slit 13. The width of the tip of the protrusion 34 is wider than the recess 15 at the back of the slit 13. The protrusions 34 are formed by punching and bending a metal plate constituting the upper member 2, and therefore the height h (see FIG. 4A) is equal to the thickness of the metal plate constituting the upper member 2.
These protrusions 34 can be inserted into the slit 13 from the insertion opening 14 of the slit 13 when the upper member support 30 is inserted into the lower member support 10 from behind the lower member support 10. In a state where the upper member support 30 is inserted into the lower member 1 from behind the lower member support 10, the base of the protrusion 34 reaches the position of the recess 15 behind the insertion opening 14 of the slit 13.

Holes 36 are provided in front of these protrusions 34 in the side wall 31 of the upper member support 30 of the upper member 2. The interval between the holes 36 is the same as that of the protrusion 34. In the illustrated example, three holes 36 are provided at the same interval.
Furthermore, in the illustrated embodiment, the front wall 32 of the upper member support 30 of the upper member 2 is also provided with protrusions 35 formed by cutting out part of the front wall 32 at regular intervals vertically. The vertical interval is the same as the opening 16 and the recess 16 ′ provided in the lower member support 10 of the lower member 1. The widths of these protrusions 35 are slightly narrower than the opening 16. In the illustrated embodiment, two projections 35 are provided below the upper member support column 30, but three or more at the same interval or four as many as the slits 13 and the recesses 13 'may be provided. I can do it. The upper and lower positions thereof correspond to the protrusions 34 provided on the side wall 31 of the upper member support 30 of the upper member 2 one by one.

  Such lower member 1 and upper member 2 are assembled as follows. First, the positional relationship as shown in FIG. 1 is set, and then, as indicated by an arrow, the upper member strut portion 30 of the upper member 2 is inserted into the lower member strut portion 10 from behind the lower member 1. At this time, a part of the protrusions 34 provided on the side wall 31 of the upper member support column 30 of the upper member 2 is inserted from the insertion opening 14 of the slit 13 provided on the side wall 11 of the lower member support 10 of the lower member 1. Alternatively, it is fitted into the recess 13 '. Further, when the upper member column 30 of the upper member 2 is slid forward relative to the lower member column 10 of the lower member 1 and the protrusion 34 is inserted into the back of the slit 13, the protrusion 34 is positioned at the concave portion 15 of the slit 13. Reach. At this time, some of the protrusions 35 on the front wall 32 of the upper member support column 30 are inserted into the opening 16 or the recess 16 ′.

  Next, when the upper member 2 is pushed from above into the lower member 1 from above, the base of the protrusion 34 fits into the recess 15 of the slit 13 as shown in FIGS. 2 and 4A. Include. In this state, the base of the protrusion 34 functions as a stopper by fitting into the recess 15 of the slit 13, and the protrusion 34 does not come out of the insertion port 14 of the slit 13, so that the upper member support 30 of the upper member 2 is the lower member. 1 does not come out of the lower member support 10.

  Further, from the state shown in FIG. 2 and FIG. 4A, the upper member strut portion 30 of the upper member 2 is slid forward with respect to the lower member strut portion 10 of the lower member 1 as indicated by the arrow, and the projection 34 Is inserted into the slit 13 as shown in FIGS. 3 and 4B, the tip of the protrusion 34 is inserted into the slit-like vertical regulating portion 18 whose vertical width is narrower than the concave portion 15. Thereby, the vertical movement of the upper member support | pillar part 30 of the upper member 2 with respect to the lower member support | pillar part 10 of the lower member 1 is controlled. Thereby, the attachment of the upper member 2 to the lower member 1 is completed. FIG. 2 is an overall view of the ridge tile beam support fitting with the upper member 2 attached to the lower member 1 in this manner.

Thus, when inserting the upper member support | pillar part 30 of the upper member 2 in the lower member support | pillar part 10 of the lower member 1, the required height from the leg part 20 to the beam support part 40 is determined, and several from below are determined. It is determined whether the projection 34 is inserted into the slit 13. That is, the height from the leg portion 20 to the beam support portion 40 can be selected depending on how many protrusions 34 are inserted into the slit 13 from below.
After the upper member 2 is attached to the lower member 1 in this way, the hole 17 of the lower member support column 10 and the hole 36 of the upper member support column 30 partially coincide with each other. If attached, the lower member 1 and the upper member 2 can be more securely fixed.

The tile beam support bracket can be firmly fixed when it is fixed to the portion of the tree 51 that supports the base plate 52 from below.

Next, a roof tile 53 is spread on the roof base plate 52. The roof tiles 53 are stacked in order from the eaves side of the roof to the ridge side along the roof gradient, that is, from the bottom to the top.
Thereafter, the roof tile is stacked on the frame body 1 of the roof tile 53 and the roof tile support member. For example, face roof tiles, roof tiles 54 and 55, and kanmuri tiles 57 are stacked while being joined together in the longitudinal direction of the ridge to construct a ridge tile.

  For example, although a pair of face roof tiles are attached to both sides of the ridge tile support member, since the face tiles are not used in the illustrated example, the ridge tile support member is divided at the center portion between the ridge tile support member and the side roof tiles 53. Put the unsupported roof tile 54. First, the roof tiles 54 are sown along the roof ridge while the ends of the plurality of roof tiles 54 are attached and joined together along the ridge. Next, on the roof tile 54, a pair of left and right roof tiles 55, 55, which are divided into two parts by removing the central portion in a strip shape, is placed. The pair of left and right roof tiles 55, 55 that have been divided into two by removing the central portion in this way is placed on the installation width of the roof tiles 55, 55 above the lower roof tile 54. This is to make it narrower. The length of the roof tiles 55 and 55 is the same as that of the roof tile 54 below. The roof tiles 55 and 55 are also stacked on a plurality of pairs of roof tiles 54 in order while joining the end portions along the ridge. The roof tiles 55, 55 are provided with holes in the opposite portions of the middle portion thereof, and the pair of roof tiles 55, 55 are bound together and fixed to each other using this hole.

  Further, before and after the roof tiles 54 and 55 are rolled, a roof tile beam 56 made of square or the like is fitted into the beam support portion 40 at the upper end of the upper member 2, and a nail is inserted from a nail hole 43 on the side surface of the beam support portion 56. To fix. As a result, the ridge tile beam 56 is held horizontally and placed between the roof tiles 55, 55.

  Finally, the roof tile 57 is placed on the roof tile 55, and the center portion of the cylindrical portion is almost on the ridge tile beam 56 as shown in FIG. The canopy roof tile 57 is placed on the ridge tile beam 56 while the string portion having a thick end portion is overlapped and joined to the end portion of the cylindrical portion of the other adjacent rim cover tile 57 and joined to both sides of the ridge tile beam 56. It spreads so as to cover a part of the roof tile 55, 55. Then, the roof tile 57 is fixed to the ridge tile beam 56 with a wood screw or the like. Thereby, the construction of the roof tile is completed.

  In the present invention, there is provided a roof tile beam support bracket that can stably support a roof tile beam even if it is installed in the tilted ridge when it has a tilted ridge such as a ridge roof or a dormitory roof. Therefore, it has the industrial applicability that the construction of roof tiles, particularly ridge tiles, can be facilitated.
