Detailed Description of the Invention

Industrial application fields

  The present invention relates to a bottom plate surface structure of a tiled bar-roofed roof in which the flow direction of liquid is regulated and flowed in a uniformly distributed state. The liquid is used for roof cooling, heat collection, snow melting or heat dissipation.

[0002]
[Prior art]
The applicant has a history of conducting research and commercialization of various flow regulation sheets that are used by being bonded to the roof surface. As an example, a path that forms an exposed liquid flow that absorbs a part of the flowing liquid and the remaining part slides on the surface, and a sub-flow path with a large liquid impregnation holding amount located on the side of this path are arranged. There is a structure in which the liquid flow has directionality due to the difference in flow velocity of the liquid flow moving through these paths. For example, it is described in Japanese Patent No. 3704591.

Problems to be solved by the present invention

  The bottom plate of a tiled bar thatched roof with such a flow-down regulating sheet is easily deformed to a middle height because the side edges on both sides are fixed in the vertical direction by the tiles. Factors of deformation include thermal deformation of the bottom plate itself due to solar radiation during the wind-tightening work during roofing work, due to the pressing of the bottom plate material on the base plate. The deformation appears in the form of a bowl in the flow direction of the liquid, and the flowing liquid is divided into left and right parts and guided to the side surfaces of the roof tiles to form a flow that converges on both side edges of the bottom plate.

According to the conventional arrangement form of the flow down regulation path, it is difficult to suppress the behavior of the liquid drifting left and right due to the bowl-shaped deformation of the bottom plate. A large amount of liquid that collects toward the side edge of the rod is guided to the side of the rod to form a high-speed flow, and the effect of correction is lost. As a result, the bottom plate surface does not function effectively as a heat exchange surface.
When the roof surface forms a snow melting surface, a cage-like residual snow is generated at the center of the bottom plate. Further, if the roof surface is a heat collecting surface, the amount of heat collected is reduced and the rise in hot water temperature is hindered. If it is a cooling roof, temperature nonuniformity will arise in the baseplate surface, and a cooling effect will fall.

Means for solving the problem

In order to solve the disadvantages of the prior art, the surface structure of the bottom plate of the tiled bar thatched roof according to the present invention is characterized by the arrangement form of the flow path of the liquid. Specifically, less liquid impregnation stockpile, absorbs part of the liquid flowing down the main flow down path the rest forms the mainstream fast flow of liquid exposed sliding surface, the side of the main flow down path And a sub-flow path that has a larger liquid impregnation amount than the main flow path, and forms a sub-flow having a slower flow velocity than the main flow, and the main flow path is located substantially in the center of the bottom plate. A first main flow path, and a second main flow path disposed on both sides of the first main flow path, and the sub flow path is an outer sub flow path in contact with each of the tiles on both sides. The inner sub-flow path is located at the boundary between the first and second main flow paths. The first main flow path has a larger width than the second main flow path.

Action

The liquid-absorbing material forms a flow path with an arbitrary width. The liquid flows down along the flow path of this arbitrary width. The liquid absorption material is composed of a main flow path with a small liquid impregnation holding amount and a side flow path with a large liquid impregnation holding amount located on the side of this main flow path, and on the side of the main flow of the liquid flowing down the main flow path. A side flow is arranged, and the liquid flows in a state of being densely packed over the entire width of the liquid absorbing material.
Since the main flow path has a small amount of liquid impregnation, it forms an exposed main flow that slides along the flow path along the flow direction of the liquid-absorbing material. A slow side flow with a relatively low flow rate is formed.

The first of the main flow paths is in the approximate center of the roof bottom plate. When the bottom plate is deformed in the shape of a bowl, the flow of the first main flow path forms an exposed stream with a thin film at the center and a thick film on the left and right due to this bowl-shaped bulge. The exposed flow with a thin film formed near the center has a relatively slow flow velocity compared to the left and right flows. The left and right mainstream flows on the first main flow path are in contact with a part of the main flow with a slow flow velocity and the substream flow of the inner subflow path, and the boundary between the two is maintained by the speed difference and channeling to the outside is prevented. Hard to occur. Further, the substream of the inner subflow path is in contact with the flow having a high flow velocity that travels along the second main flow path, and the boundary between the two is maintained by the flow velocity difference, and channeling to the outside hardly occurs. Furthermore, since the outer secondary flow path is installed between the second main flow path and the side surface of the tile rod, the flow of the second primary flow path comes into contact with the slow flow of the outer secondary flow path from the side of the tile rod. The flow is isolated, and the flow along the side of the rod is unlikely to occur.
When a flow is generated from the first main flow path to the inner sub flow path, the second main flow path captures this, and the flow of the slow flow velocity of the outer sub flow path is located in contact with the side surface of the tile rod. Therefore, the lateral movement of the liquid is diluted, and it becomes difficult to make a wasteful flow that runs linearly by adhering to the corners of the side surface of the rod. Since the first main flow path is tailored to be wide, the flow rate is large and acts to ensure a sufficient amount of liquid on both sides of the ridge-shaped ridge.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 and 3 are perspective explanatory views showing an example of a bottom plate surface structure of a tiled bar thatched roof according to the present invention.
The bottom plate 1 of the roof tiled roof has a plurality of liquid flow paths formed on the surface. These liquid flow paths are composed of a main flow path and a secondary flow path. The main flow path has a small liquid impregnation holding capacity and absorbs a part of the flowing liquid and forms a main stream of the exposed fast flow liquid in which the remaining part slides on the surface. The sub-flow path is located on the side of the main flow path to form a sub-flow having a slower flow velocity than the main flow, and has a larger liquid impregnation amount than the main flow path.

  In the illustrated example, the main flow path is composed of a first main flow path A located substantially in the center of the bottom plate, and second main flow paths B arranged on both sides of the first main flow path A. Has been. The sub-flow path is composed of an inner sub-flow path C interposed between the first and second main flow paths A and B and an outer sub-flow path D in contact with each of the tiles 2 on both sides. . The first main flow path A has a larger width and a larger flow rate than the second main flow path B. The horizontal width of the first main flow path A in the illustrated example is the sum of the horizontal widths of the second main flow paths B on both sides. The lateral width of the first main flow path A can be set larger by adding the amount corresponding to the width of the undulation than the sum of the lateral widths of the second main flow path B taking into account the undulation of the bottom plate.

  In the example shown in the drawing, the main flow path is thin and forms a main flow in which a large amount of liquid that cannot be impregnated and retained flows down while sliding on the surface of the path. The sub-flow path with a large liquid impregnation holding amount disposed on both sides of the main flow contains more liquid than the main flow path, and a slow sub-flow with a relatively low flow rate is formed along this sub-flow path, The main flow and the sub flow of these liquids are located adjacent to each other and flow down along the entire surface of the liquid absorbing material.

  FIG. 2 shows an example in which at least one recess passage E is provided in the inner sub-flow path. When used as a snow melting roof, if the accumulated snow water is sucked up, this recess passage functions as a makeup water passage.
