Description

  The present invention does not cause the attached external structure to be blown away by strong winds or gusts such as typhoons, and does not impose a burden on the roof tiles that constitute the tile roof, and can obtain a stable strength. The present invention relates to a method for constructing an external structure on a tile roof to which a system, a greening structure, and the like can be attached, and an exterior structure.

In recent years, combined with social and political conditions, the expectations for solar energy conversion modules are increasing, and the demand for mounting solar panels on the roof of existing structures and buildings has also increased. Yes.
On the other hand, in order to reduce carbon dioxide, attempts to reduce the temperature and perform photosynthesis by greening the roof surface are also actively conducted.

  Conventionally, as a structure for mounting a solar energy conversion module on a tile roof, for example, as described in Patent Document 1, a roof tile at a predetermined location is replaced with a special support tile, and a vertical support is attached to the attached special support tile. A structure in which a crosspiece and a horizontal crosspiece are fixed and a functional panel is attached to these crosspieces has been proposed.

JP 2006-144267 A

However, in Patent Document 1, since the functional panel is attached above the roof surface made of roof tiles, the functional panel is attached so as to protrude upward (one step higher) from the roof surface made of roof tiles. Thus, when a strong wind such as a typhoon or a gust of wind blows, wind pressure acts on the functional panel from the side or from the lower side, so that there is a problem that it is easily blown away.
Moreover, in the said patent document 1, it replaces with the existing roof tile as mentioned above, and a support tile is attached, As this support tile, in order to support a vertical beam, a horizontal beam, etc. on it, it is special. It was necessary to use roof tiles, and could not handle any roof tiles.
Furthermore, although the weight of the function panel is main here, the total weight has to be received by several supporting roof tiles, and the addition to the individual supporting roof tiles is large. Furthermore, when existing roof tiles are partially removed and fixed, there is also a problem that a stable strength cannot be obtained because the base structure is wooden (plywood).

  Therefore, the present invention provides an external structure to the tile roof that can obtain a stable strength without imposing a burden on the roof tile that constitutes the tile roof, and can also be attached to a solar cell system or a greening structure. The purpose is to propose construction method and exterior structure.

  The present invention has been proposed in view of the above, and a step (first step) of exposing a substantially rectangular region of a base by removing a plurality of roof materials constituting a tiled roof, and an exposed bottom On the ground, a step of constructing a waterproof layer and disposing a protruding takeout fitting (second step), and a step of arranging a crosspiece so as to span the plurality of takeout fittings (third step) And a step of constructing an external structure between the crosspieces (fourth step). The present invention relates to a method for constructing an external structure on a tiled roof.

  Furthermore, the present invention is an exterior structure in which an external structure is constructed in a substantially rectangular area of a tile roof, and the external structure is provided under a substantially rectangular area where a plurality of roof materials are removed and exposed. On the ground, a waterproof layer is constructed, and protruding takeout fittings are arranged, and a crosspiece is placed over a plurality of takeout fittings, and is constructed between the crosspieces. A characteristic exterior structure is also proposed.

The present invention is a method for constructing an external structure to a tile roof in which the tile roof is partially removed (substantially rectangular region) and an external structure such as a solar cell system or a greening structure is constructed in the substantially rectangular region. Since the external structure is not constructed so as to be placed on the tile roof, the plane height can be kept low. For this reason, the surface of the external structure can be formed at substantially the same height as the surface of the tile roof, the external structure does not become a wind and rain resistance, and there is no risk of being blown away by strong winds or gusts such as typhoons. .
The first step of exposing the substantially rectangular region of the foundation by removing a plurality of roofing materials constituting the tile roof also constructs a waterproof layer on the exposed foundation, and has a protruding takeout metal fitting. The second step of disposing, the third step of disposing the crosspieces so as to cross over a plurality of carry-out brackets, and the fourth step of constructing an external structure between the crosspieces are special. Since it can be easily constructed without using any other member or device, the workability is extremely high.
Furthermore, a burden is not given to the roof material (roof tile) which is not removed in the first step.
Also, it can be applied to tiled roofs with different specifications, and even if there is damage to the existing vertical rails and groundwork, a waterproof layer can be constructed while repairing in the second step. It is also possible to construct an external structure such as a solar cell panel with specifications.
In addition, the overall weight can be reduced, and the housing is not affected as compared with the case of construction on a tile roof. And it can construct | assemble without giving load, such as a weight and rain, to a tile roof.
Furthermore, since it does not protrude from the roof surface, it has excellent design properties, and solar cells and the like can be arranged without impairing the design properties of the tile roof.

  Furthermore, the exterior structure to be constructed by the construction method of the external structure on the tile roof is constructed and disposed on the ground exposed by removing the roof material (roof tile) as described above. Since the crosspieces are bridged between the carry-out brackets and an external structure is constructed between the crosspieces, there is no risk of being blown away by strong winds or gusts such as typhoons. Etc. can be installed.

The construction method of the first embodiment of the present invention comprising the above steps is to remove the tile roof partially (substantially rectangular region 1A) and use the solar cell system 9 as an external member in the substantially rectangular region 1A. Since it is to be mounted and not placed on the tile roof, the plane height can be kept low, and the surface of the external structure can be formed to be approximately the same height as the surface of the tile roof. Does not become a resistance against wind and rain, and there is no risk of being blown away by strong winds such as typhoons or gusts.
In addition, since any of the first to fourth steps can be easily performed without using any special member or apparatus, the workability is extremely high.
Furthermore, no burden is given to the roof material (roof tile) 2 that is not removed in the first step.
It can also be applied to tiled roofs with different specifications, and even if there is damage to the existing vertical rails and groundwork, it is possible to attach the vertical covering exterior material while repairing it in the second step. It is also possible to construct an external structure of a solar cell panel with various specifications.

  In the second embodiment shown in FIG. 6, the crosspiece 8 is not directly attached to the takeout fitting 7A similar to the first embodiment, but the L shown in FIG. 5 (e) is attached to the takeout fitting 7A. A vertical beam member 7B shown in FIG. 5 (d) is fixed via a character material 7C, and the horizontal beam member 8 and the solar cell similar to those of the first embodiment are arranged at arbitrary positions in the longitudinal direction of the vertical beam member 7B. The configuration is such that the panel 9 is attached, and the other configuration is substantially the same as that of the first embodiment, so the same reference numerals are given and the description is omitted.

The vertical beam member 7B used in the second embodiment has a substantially rectangular cross section including a side adjustment groove 75 that opens on the side and an upper adjustment groove 76 that opens on the upper side. In 76, the heads of the couplers 7i and 7f, which are hexagon bolts, are fitted and held, so that the couplers 7i and 7k can slide in the longitudinal direction.
The width of each adjustment groove 75, 76 is smaller than the length connecting the opposing angles of the top surfaces of the heads of the respective connectors 7i, 7f, and larger than the distance between the opposing sides. , 7k are fitted and held in the respective adjustment grooves 75 and 76, and are held without rotating during tightening. Further, the opening width is smaller than the heads of the couplers 7i and 7f with respect to the groove widths from which the heads of the couplers 7i and 7f can be recessed from the adjustment grooves 75 and 76, and the legs of the couplers 7i and 7f. Since it is formed larger than the thickness of the portion (male screw portion), for example, the head does not fall off during sliding.
Then, the fasteners 7j and 7g, which are tightening nuts, are screwed and fastened to the leg portions (male screw portions) of the connecting tools 7i and 7f, so that they can be adjusted and fixed at arbitrary positions. These mechanisms are the same for the groove 81 and the mounting bolt 8c (nut 8d) of the crosspiece 8 and can be adjusted in a state of being fitted in a groove formed continuously in the length direction. Since it can be fastened and fixed at an arbitrary position, it is effective as an adjustment mechanism in the length direction.

The method of attaching the solar cell panel 9 to the tile roof in the second embodiment is substantially the same as that of the first embodiment, but also uses a different configuration from the first embodiment as described above. The procedure using the crosspiece 7B and the L-shaped material 7C is shown below.
First, the first step of exposing the substantially rectangular region 1A of the base, the exterior material 3 is attached as a waterproof layer on the exposed base 1A, and the mounting bracket 6 is fixed to the connection portion of the exterior materials 3 and 3 The process up to the second step of fixing the take-out metal 7A to the mounting metal 6 is exactly the same as in the first embodiment.

As the third step, in the first embodiment, the crosspieces 8 are arranged so as to be bridged over the plurality of carry-out fittings 7A. However, in this second embodiment, each piece of the carry-out fitting 7A has a piece material. The L-shaped material 7C is fixed (connector 7k, fastener 7l), and the vertical beam member 7B is bridged and fixed (connector 7i, fastener 7j). At that time, the L-shaped material 7C may be fixed in advance before the attachment of each takeout fitting 7A.
In this state, the vertical beam member 7B can be (finely) adjusted to an arbitrary position in the length direction by loosening the fastener 7j.

Thereafter, the horizontal beam member 8 is attached to the fixed vertical beam member 7B. The attachment method itself is exactly the same as in the first embodiment, and the hexagon held in the upper adjustment groove 76 of the vertical beam member 7B. A fixing bracket 8B having a hook-shaped locking portion is attached to the bolt 7f, and the nut 7g is engaged with the hook-shaped locking portion of the fixing bracket 8B engaged with the engaging portion 831 of the crosspiece 8. As a result, the head of the hexagon bolt 7f is locked in the upper adjustment groove 76, and the fixing portions 83, 83 of the horizontal beam 8 are integrally fixed to the upper surface of the vertical beam 7B.
In this state, by loosening the nut 7g, it is possible to (finely) adjust and fix the horizontal beam member 7A to an arbitrary position in the length direction of the vertical beam member 7B.

  Subsequently, as a fourth step, an external structure is constructed by attaching the solar cell panel 9 as an external member between the crosspieces 8 and 8 just as in the first embodiment.

  In the second embodiment constructed in this way, the horizontal crosspiece 8 is not directly attached to the carry-out fitting 7A, but includes adjustment mechanisms in the length direction (side adjustment grooves 75, upper adjustment grooves 76). Since it is the structure attached via the vertical crosspiece 7B, it is suitable when constructing | assembling a solar cell system (external structure) over a wide area.
