Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a snow melting device with a sloped roof suitable for snowy regions.

(Background technology) Snow on sloping roofs can cause damage to buildings if left untreated, or lightning can strike passersby or garden trees, so snow removal is carried out, but this work can also cause falls. , is extremely dangerous. Therefore, it is necessary to eliminate the need for removing snow or reduce the number of times it is removed, and to prevent lightning strikes. To this end, it is desirable to melt snow while preventing snow from falling on the roof.

Conventionally, such snow melting equipment has a flat roof type with a roof that is gently sloped toward the center, and the melting snow is drained from a central duct pipe. This makes it difficult to apply to the desired sloped roof.

In addition, it has been proposed to install a sheet heater on the entire slope of a sloped roof to electrothermally melt snow, but this requires high installation and maintenance costs.

(Objective of the Invention) An object of the present invention is to provide a snow melting device for a sloped roof which is relatively inexpensive and is most suitable for a sloped roof.

(Structure of the Invention) In accordance with the above-mentioned object, the present invention forms a valley gutter section as a heat insulating structure below the sloped roof, and sequentially receives accumulated snow from above, and drains the melted snow in the valley gutter section. In addition, the load in the valley gutter part is supported by the joists, and the valley gutter part etc. is isolated from the inside of the building so that it can be installed outdoors. The front and rear joists interposed between the upper end of the outer wall of the building and the lower end of the slanted barrel on the outer wall are integrally or integrally extended and protruded to the side of the outer wall to serve as a support part;
A rising parapet part is continuously installed at the tip of the support part, and a valley gutter part is provided on the support part from a higher position than the upper end of the parapet part to the parapet part along the sloped surface of the roof, and the valley gutter part is placed on the support part. The gist of the present invention is a snow melting device for a sloped roof, characterized in that a gutter portion and a drainage pipe connected to the gutter portion serve as a heat insulating structure.

Note that the joists of the present invention can be used as floor joists, ceiling joists (
The present invention will be described below with reference to the drawings showing the embodiment. In the embodiment, only the old roof part of an existing frame structure building l is removed and Instead, use a steep slope (45°) using the framed wall construction method.
A new sloping roof 6 (from 6o0 to 6o0) is installed on the eave girder 4 on the pillar 3 forming the outer wall 2 of the building 1 via an architrave 5, and the interior is made into a space 7 for living or storage. Give an example.

This sloping roof 6 is constructed by placing and fixing a large number of (floor) joists 8 made of 2 x 6 inch structural materials at intervals of 45 cm from center to center in the front and back direction with the gable side as a reference on the upper end of the building's outer wall 2. A large number of 2 x 6-inch structural timbers 10 are erected between the upper central ridgepoles (not shown) at intervals of 45 mm, and fall prevention devices (not shown) are placed between the 8 joists and 1 o of the slanted barrels to form a frame. 1 roof base layer of structural plywood is placed on the tarp wood 10, and floor plywood 9 is placed on the joist 8.
It is constructed by extending the . In the figure, 13 is a partition plywood on the indoor side.

The above-mentioned joists 8 are therefore interposed between the upper end of the outer wall 2 of the building 1 and the lower end of the inclined oak tree 1o on this outer wall, but at this time, each joist 8 is longer than the width of the building 10. ,
In this example, each 5o is placed on the side of the outer wall 2, that is, in the needle direction.
cIR is integrally extended and protruded, and the extended protrusion portion forms a support portion 15.

A structural member 16 is erected at the tip of the support portion 15 of each joist 8, upper and lower connecting members 17 and 17 are arranged on the structural member 16, and an exterior member 18 is stretched on the outside. Support part 15
A parapet part 19 extending in the vertical direction is continuously installed perpendicularly to the parapet part 19 at an external height of 60 cm. An eave ceiling 31 is provided between the lower end of the rosette part 19 and the outer wall 2 to cover the gap. On the other hand, the sloped roof 6
The roof sheathing material 13 is stretched over the roof base 11 from the ridge part, but from the lower part of the parapet part 19, which is less than 1 m below, and is higher than the upper end of the parapet part 19, the roof sheathing material 13 is stretched from the lower surface side that overlaps with the roof sheathing material 13. A valley gutter part 21 is formed and provided downward along the roof slope.

This valley gutter section 21 is connected to the parapet section 1 from the roof slope surface.
9, and has a cross-sectional shape that substantially follows the upper surface thereof, and is expanded upwardly and is located on the support part work 5. That is, the valley gutter portion 21 rises through the roof base 11, the bottom plate material 25 on the support portion 15, and the bottom plate material 26 from the intermediate position of the support portion 15 toward the parapet portion 19, and,
It includes a cap wood part 27 that covers the upper end of the parabet part 19,
An integral metal plate 24 is attached to the folded part 2B on the outside of the parapet part 19, and a substantially U-shaped snow melting receiving part 22 is formed inside the central part〇And this metal plate A foamed urethane heat insulating material 23 is lined and filled over the entire lower surface of the 24 to insulate the snow melt receiving part 22, the parapet part 19, the support part 15, and the slope of the roof 6 via the valley gutter part 21. It is considered to be an insulated structure.

Reference numeral 29 in the figure indicates a drainage pipe connected to the valley gutter section 21 at one or more locations, and this drainage pipe 29 communicates with the snow melting receiving section 22 and is introduced into the sewer system. A similar heat insulating material is provided in the entire length direction of the top and bottom, and is covered with this.

A heat insulating material 30 connected to the lower floor is interposed on the indoor side of the slanted oak 100 of the roof 6 to prevent heat dissipation of indoor warm air.

In addition, 20 in the figure is a bent part of the parapet part 19 that closes the valley gutter part 21 at both ends in the front and rear direction.

14 is a ventilation system for 60 sloped roofs, and 32 is a raised edge of the eave ceiling 31.

By the way, it is particularly desirable that the joists forming the support part of the present invention are integral, but they may also be integrally connected, and in this case, if possible, a steel frame or the like is attached along these connecting parts so that the joist is integrated. It is desirable to sufficiently reinforce the connecting parts. Note that additional reinforcement such as steel frames can of course be installed in the case of the above-mentioned integral joist, and in this case, bolts and screws with a length of about 50 to 100 CI11 from the support part of the joist to the indoor side are used. It is best to fix it by stopping it.

Further, although the supporting portion was approximately 50,011 mm in this example, it may be longer than this, for example, approximately 1 m. However, it is not desirable to make the width too narrow. It is more desirable for the appearance of the parapet to extend in the vertical direction of the joists, and its exterior material can be made of the same material as the roof exterior material.

The joists are placed in the front-back direction, but it is not always necessary to use all the joists as supporting parts, and
If there is a shortage of joists, additional joists can be provided. Therefore, whether to use all the joists, to install additional joists, or to install every one or several joists should be determined by taking into consideration the structure of the building and the amount of snow in the area. Note that when there is a gap between the joists used as supporting parts, such as when installing every other joist or every few joists, it is of course possible to install a separate structural member as an auxiliary support.

The gutter section may be constructed on-site or pre-unitized at the factory, but when installing it, it is recommended that the roof sheathing material be placed on top at the upper end of the sloping roof side, polymerized and interposed with a sealant. Effective for waterproofing. Moreover, the present invention.

The reason why it is located higher than the parapet is to prevent drowning. Note that the gold jlFiE in the valley part can be made of aluminum, steel plate, etc., and a painted surface can be further provided on the surface.

In the above embodiment, a steeply sloping roof with a living space provided inside is used, but the roof is not limited to this and can be applied to the roof of an ordinary roof frame. In the above example, the joists are used as floor joists because they have a space for living, etc., but in a normal shed structure that does not have such a space, the joists of the present invention correspond to ceiling joists (beams). , the joist of the present invention is used in a broad sense including these.

The present invention is not limited to the above-described embodiments or explanations, and specific materials, dimensions, shapes, structures, etc. may be variously changed without departing from the gist of the invention.

(Effects of the Invention) The present invention provides for the front and rear joists interposed between the upper end of the building's outer wall and the lower end of the inclined barrel on the outer wall to integrally or integrally extend and protrude to the side of the outer wall to form a supporting part. A rising parapet part is continuously installed at the tip of the support part, and a valley gutter part is provided on the support part from a higher position than the upper end of the parapet part to the parapet part along the sloped surface of the roof, and the valley gutter part is placed on the support part. Since the drain pipe and the drain pipe connected thereto are characterized as a heat insulating structure, it has the following effects.

That is, in the present invention, since the valley gutter part is integrally or physically extended and protruded, the load is distributed to the building side, so that the temperature of the snow on the sloped roof decreases at the boundary with the roof. Even if it slides downward due to sunlight or sunlight and concentrates on the valley gutter, the load can be effectively supported and the valley gutter will not be deformed or damaged.

In addition, the lower layer of snow melts easily, the upper layer is cold like the outside air, and the middle layer has heat retention and separates the upper and lower layers, so the snow that melts at the boundary with the sloped roof gradually becomes sloped. It slides down the surface until it reaches the valley gutter, but this valley gutter stops the snow from falling under the roof in the form of snowflakes.

And the valley gutter part is an insulated structure.

The snow concentrated here is melted by keeping the lower layer of snow covered by the middle layer of snow and the valley gutter warm from the cold air outside, while the drainage pipe connected to the valley gutter drains warm air from the sewers, etc. By guiding and promoting this, the drainage pipe can discharge the melt water in the heat-retaining state, which is advantageous for snow melting.

In addition, the valley gutter is an independent outdoor installation that is completely isolated from the inside of the building, and the sloped roof side of the valley gutter is located higher than the top of the rosette, so it prevents swamping, etc. Get η
It is advantageous on the water.

Further, the rose pet portion has a decorative effect that accentuates the exterior of the building. As described above, the present invention can provide a snow melting device that is suitable for sloped roofs at a relatively low cost.
