Outside insulation structure of folded-plate roof

The present invention relates to an outer heat insulating structure of a folded-plate roof, and more specifically, in a metal folded-plate roof made up of a valley and a mountain, an outer heat insulating means made of plants and the like in the valley and an outer made of heat insulating material in the mountain. The present invention relates to an outer heat insulating structure of a folded plate roof on which heat insulating means is formed.

The folded plate roof has a structure in which folded metal plates with a mountain-shaped cross section having a peak and a valley are joined and arranged side by side through a tight frame, etc., which is robust and relatively easy to construct. For this reason, it has recently been widely used not only in temporary buildings but also in stores such as suburban convenience stores and factories.

However, the folded-plate roof lacks heat insulation performance, so there is a problem that it is hot in the summer and cold in the winter, and it is difficult to control the temperature inside the building, and it is necessary to bear a high cost for air conditioning. For this reason, the heat insulating double folded plate roof structure that is constructed by stacking folded plate-shaped roof materials in layers and loading the insulation between them can be constructed using the same type of roof materials, so energy-saving buildings Has been used frequently.
However, such a double structure has a high construction cost and requires a long construction period because a special connecting bracket is required to connect the lower roof plate and the upper roof plate at a predetermined interval. Further, such a configuration in which a heat insulating material is interposed between the lower roof plate and the upper roof plate is a so-called inner heat insulating method, and there is a problem that the heat insulating performance is inferior to the outer heat insulating method. Moreover, in order to renovate an existing folded plate roof to make a double roof, it is necessary to bear a considerable cost such as requiring strength reinforcement.
In addition to the above, conventional folded-plate roofs overlook measures against the summer heat island phenomenon regardless of single or double structure.

The present invention is an outer heat insulating structure of a folded plate roof composed of a folded plate in which a valley portion and a mountain portion are continuously formed, and the outer heat insulating structure includes a first heat insulating means of the valley portion and a first portion of the mountain portion. The heat insulating water supply / drainage means formed at the bottom of the valley, the root guard interposed between the bottom of the valley and the water retention / drainage means, It is composed of a planting layer constructed on the water retention / drainage means, and the water retention / drainage means retains and drains rainwater penetrating from above or irrigation by other means, and supplies and holds the retained moisture to the root of the plant. In order to grasp the soil to be made, it consists of a drain plate in which a plurality of water retaining portions and drainage portions are integrally formed, the planting layer is composed of a customer soil layer and plants planted on the customer soil layer, The second heat insulation means in the mountain is a heat insulating material covering the mountain Ri construction was to provide external insulation structure of folded plate roof is intended to solve the above problems.

Moreover, in the outer heat insulation structure of said folded-plate roof, it may be set as the structure which embeds an irrigation pipe in the soil layer of a planting layer .

Further, in the outer heat insulating structure of the folded plate roof, the drainage portion of the drain plate constituting the water retention / drainage means is formed by a straight pipe having a hole portion on the upper surface formed to cross and communicate vertically and horizontally, The water retaining part may be constituted by a recessed space formed by being surrounded by each straight pipe, and the direct pipe may be provided with a plant root engaging part .

Still further, in any one of the above-described outer heat insulating structures of the folded-plate roof, the heat insulating material covered by the mountain portion is composed of a fiber layer in which the branches and leaves of the plant of the planting layer are prone to grow and engage easily, and the heat insulating material It may be configured to improve the heat insulation function by planting on top.

In the first heat insulating means of the valley portion, the drain plate is constituted by a resin plate in which a plurality of water retaining portions and drainage portions are integrally formed, and this is fixed to the bottom surface of the valley portion with a double-sided tape. At this time, it is desirable to stretch a resin-made root guard between the bottom of the valley and the drain plate to prevent the root of the plant from entering.
Light soil is laminated on the drain plate to form a soil layer with a predetermined thickness, and irrigation pipes are installed in the soil. Rainwater penetrating from the upper part of the soil layer or irrigation by the irrigation pipe reaches the drain plate as the water retention / drainage means, and is retained and drained. Is drained through the drainage section.
Since the drain plate has a large number of irregularities formed by small sections such as a water retaining portion and a drainage portion, the drain plate is gripped to prevent random movement. That is, the drainage part of the drain plate constituting the water retention / drainage means is constituted by a straight pipe having a cross section communicating vertically and horizontally and having a hole on the upper surface, and the water retention part is surrounded by each straight pipe. It is constituted by a recessed space to be formed, and the customer's soil is gripped by such a recessed space.

The end of the heat insulating material is located in the soil layer between the peaks and valleys. The heat insulating material of such a material covered in the mountain part makes it easy for the branches and leaves of the plant vegetated on the soil layer in the valley part to advance and engage, and it is easy to realize the overgrowth of the plant also in the mountain part. Make the effect noticeable.

Sedums (succulents) such as Alpum, Giraffe, Mexican perennials or turf are vegetated on the soil layer. In particular, sedum flowers can be enjoyed all year round and maintenance is not required, and from May to September, a beautiful landscape of red, white, yellow and pink flowers blooms in the green leaves. .
From autumn to winter, you can enjoy seasonal changes, such as storing sugar and turning red. In addition, it can withstand severe cold winds in winter, and it has such a strong property that it becomes a summer-shaped needle leaf all summer and germinates in June. Sedums that can be easily vegetated in this way basically do not require fertilizers, they are not necessary except during summer irrigation, and no chemical herbicides are required. And because the load is light, there is no need to reinforce the building, making it suitable for construction of various types of roofs such as sloping roofs.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway cross-sectional view showing an outer heat insulating structure of a folded plate roof composed of a folded plate R in which a valley portion T and a mountain portion Y are continuously formed, and the outer heat insulating structure is a valley portion T. 1st heat insulation means and the 2nd heat insulation means of the mountain part Y are comprised.
The said 1st heat insulation means in the trough part T is comprised from the water retention / drainage means (drain plate D) formed in the lower bottom part 4 of the valley part T, and the planting layer constructed | assembled on this water retention / drainage means, The said water retention / drainage means is In order to hold and drain rainwater penetrating from above or irrigation by other means, to supply the retained moisture to the root of the plant and to hold the soil of the layer S of the customer soil layer, Is composed of a drain plate D integrally formed, the planting layer is composed of a customer soil layer S and plants P planted on the customer soil layer S, and the second heat insulating means in the mountain Y is the upper bottom portion. 3 is constituted by a heat insulating material 5 covering the mountain portion Y.
In addition, between the drain board D and the bottom part of the trough part T, the resin-made root guards 4 for suppressing the influence on the roof of a plant root are interposed.

The heat insulating material 5 as the second heat insulating means is composed of a fiber layer formed of coconut shell fibers, covers the mountain portion Y, and both ends of the heat insulating material 5 extend from the mountain portion Y to the slope portion T to the customer. It is buried in the soil layer S. The heat insulating material 5 and the folded plate R (mountain portion Y) are fixed with a double-sided adhesive tape.
Further, the irrigation pipe 6 is buried in the soil layer S so as to perform irrigation in a timely manner. Rainwater or water that has permeated into the soil layer S from the irrigation pipe 6 reaches the drain plate D as a water retention / drainage means and is retained or drained.

On the soil layer S, plants P such as sedums (succulent plants) or turf are planted, and a planting layer is constituted by this plant P and the soil layer S. The drain plate D as a means constitutes a first heat insulating means in the valley T.

FIG. 2 is a partially cutaway perspective view showing the water retention part 1 and the drainage part 2 constituting the drain plate D as the water retention / drainage means. As shown in the figure, the drainage section 2 is formed by cross-communication in the vertical and horizontal directions, the cross section having a hole h on the upper surface has a trapezoidal shape, and the water retaining section 1 is formed by each straight pipe. Each is integrally formed by a recessed space 1a formed by being surrounded.

The root guard 4 is laid on the bottom surface of the valley T, and the drain plate D is fixed thereon. Next, the ridge shell fiber layer 5 is coated on the mountain portion Y, the fiber layer 5 is suspended at both ends of the mountain portion Y, and the irrigation pipe 6 is installed in the valley T space, and the soil layer S is formed on the drain plate D. Laminate.
The guest soil layer S is a lightweight artificial soil with excellent water retention, drainage, and buffering, which is made of gravel aggregates and other organic matter essential for the permanent growth of plants. The space surrounded by the straight pipe 2 a, that is, the space surrounded by the protrusion 3 a in the water retaining portion 2 or the fixing portion 3, so that the soil layer S is firmly held by the drain plate (water retaining and draining means) D. Therefore, the planting layer is stably held against wind or roof inclination. Plants such as sedums, turf and moss are planted on the soil layer S.

A part of the water is impregnated and held in the soil layer S by precipitation or drainage to the soil layer S, and the other part passes through the soil layer S and reaches the water retention part 1 of the drain plate D and is stored.

When the amount of water that reaches the drain plate D is large and cannot be accommodated in the water retaining portion 1, the water is formed in a gap (joint portion) between the end portions of each drain plate D, Or it drains suitably from the drainage part 2 through the hole h of the straight pipe 2a.

When the amount of water retained in the soil layer D is reduced and dried, the water is replenished to the plant by the water stored in the water retention unit 1.
In addition, since the drainage part 2 by the direct pipe | tube 2a is mutually connected as mentioned above, it always becomes a ventilation path and fresh air is supplied to the root of a plant and prevents various pests. be able to.

By the way, if the thickness of the soil layer S is reduced, the tension of the roots of the plants is limited, and there is a risk that the standing of the plants may be in danger, or the wind may fall down by a small amount of wind. Such inconvenience can be prevented by a large number of holes h provided on the upper surface of the tube 2a.
That is, since the root of the plant that has advanced from the soil layer S is firmly fixed and held around the hole h, the plant can easily collapse even if the soil layer S is thin. There is no.

As the plant P of the soil layer S grows, the upper part of the valley T is covered with the plant P, and the heat insulation performance of the first heat insulating means in the valley T is improved. Further, the growth of branches and leaves due to the growth of the plant P not only positively affects the first heat insulating means, but also promotes the heat insulating effect of the second heat insulating means of the mountain portion T.
That is, since the coconut shell fiber layer 5 covering the mountain portion Y is formed in a nonwoven fabric shape in which the coconut shell fibers are entangled, the branches and leaves of the plant P in the valley portion T advance and engage with the fiber layer to form the mountain portion. Y is also covered, and the heat insulation performance of the second heat insulation means of the mountain portion Y is improved.

As described above, the present invention can realize a heat insulating effect by external heat insulation that is extremely efficient compared to internal heat insulation, with a simple structure and low cost, in a building having a folded plate roof regardless of whether it is existing or newly installed. . In summer, vegetation on the roof can be expected to suppress the so-called heat island phenomenon.
