Description

  The present invention relates to a method for constructing a horizontal roof that can be safely and reliably laid from the water side to the water side along the slope of the roof base, and can be applied to both new installations and repairs, and Regarding the roof.

Conventionally, in the construction of a horizontal roof in which a heat insulating material is disposed on the back surface of the roof material, a construction method in which the roof is rolled up from the water side to the water side along the slope gradient of the roof base has been common.
However, the construction method has a problem that an operator steps on, stains or damages a roof material that has already been constructed. Further, since a scaffold is required, there is a problem that the cost is increased and the construction period is prolonged.

  Therefore, the present applicant has found a construction method disclosed in Patent Document 1 as a construction method that can be lowered from the upper side of the slope to the lower side. In this construction method, as shown in FIG. 6, the horizontal roofing board member 1 is rotated and attached to the hanging member 11 along the water upper end portion of the backup material 41.

JP-A-4-146356

  However, in the construction method described in Patent Document 1, it is necessary to transport the roofing material and the heat insulating material separately to the site, and if the roofing material is not attached so as not to be scattered by strong winds at the stage where the heat insulating material is disposed. Therefore, workability was extremely poor. In addition, if you try to install both members at the same time by attaching an insulating material to the back of the roofing material using an adhesive, the insulating material may interfere with the installation of the roofing material (mating work) and may not work. .

  Therefore, the present invention can be laid safely and reliably from the water side to the water side along the slope gradient of the roof foundation, and a method for constructing a horizontal roof that can be applied to both new installations and repairs, and The purpose is to propose a thatched roof.

The present invention has been proposed in view of the above, and a horizontal roof formed by arranging a heat insulating material on the back surface side of a side wall covering material having molded portions that engage with each other on the water upper side and water lower side of the face plate portion. A first step of fitting and temporarily attaching a protruding portion provided at the water lower end of the heat insulating material to the back surface side of the underwater molded portion of the side facing exterior material, and the above step A second side facing exterior material temporarily attached with a heat insulating material is faced in an inclined manner, and the water-side molded portion is engaged with a water-side molded portion of the side facing exterior material attached to the roof surface while rotating. A step and a rotating space in the next stage on the back surface side of the water-shaped molding part of the side covering material by pressing the water lower end of the heat insulating material of the side covering material attached in the step And a third step of providing the outer side of the underside molding portion attached in the above-mentioned step. A fourth step of fixing the roof member in a state where the engaged while rotating, to a horizontal-roofing method of constructing a roof, characterized in that it consists of.
In addition, although expressed as “turning”, it refers to a state in which the side covering material facing in an inclined shape as shown in FIG. 1A is laid in a substantially flat shape after construction, In addition, the “turning space” means that the water-side molding part of the side-laying exterior material is engaged with the water-side molding part of the water-side side covering material that has already been attached during the “turning”. It refers to the space to be.

  Furthermore, the present invention is characterized in that a continuous exterior surface is formed by the adjacent lateral exterior materials by repeatedly performing the first to fourth steps of the construction method on the roof surface. It also proposes a horizontal roof.

  The construction method of the side roof according to the present invention can be easily laid from the water side in the flow direction to the water side, and does not require an adhesive or the like. It can be applied in new construction and renovation. That is, there is no need for adjustment or application of the adhesive, and each of the first to fourth steps can be easily performed without the operator stepping on, smearing, or damaging the installed outer covering material. Scaffolding costs can be reduced, construction period can be shortened, and construction safety can be improved.

Moreover, since the horizontal roof of this invention is formed by repeating the said construction method, a continuous exterior surface will be formed beautifully.
In particular, when it is constructed so that the heat insulating material is disposed without a gap between adjacent holding members, the heat insulating layer continuous with the heat insulating material adjacent to the back surface side of the exterior surface (= heat insulating layer without heat insulating defect) Is formed.

The side view of the heat insulating material used for (d) It is a side view which shows the holding member in 1st Example.

The construction method of the horizontal roof of this invention consists of the following 1st-4th processes.
In the first step, a protruding portion provided at the water lower end of the heat insulating material is fitted to and temporarily attached to the back surface side of the water-side molded portion of the side facing exterior material.
In the second step, the side facing exterior material temporarily attached with the heat insulating material in the above step is faced in an inclined manner, and the water-side molded part attached to the roof surface is rotated under the water while the water-side molded portion is rotated. Engage with the side molding.
In the third step, the bottom end of the heat insulating material of the side covering material attached in the step is pressed and slid to the water side, and on the back side of the underwater molding part of the side covering material in the next stage. A rotating space is provided.
A 4th process fixes to a roof surface in the state engaged while rotating a holding member so that it may be arrange | positioned at the back surface side of the underwater shaping | molding part of the horizontal covering material attached in the said process.

  Before explaining each step of forming the construction method of the present invention, the side covering material, the heat insulating material, and the holding member used in the present invention will be described.

First, the side covering material has a fitting receiving portion that is a space in which a protruding portion provided at the water lower end of the heat insulating material can be fitted on the back surface side of the underwater molding portion as described above. It is provided with a rotating space for the horizontal covering material in the step. As described above, the horizontal covering material has a water-side molded part, but of course, on the water side thereof, there is a water-side molded part that engages with the water-side molded part.
Such a horizontal covering material is not particularly limited in material or shape, and is typically about 0.4 to 1.6 mm surface-coated steel sheet, laminated steel sheet, plated steel sheet, stainless steel sheet, aluminum. A known metal material such as an alloy plate, a titanium alloy plate, or a copper plate formed into a predetermined shape by roll forming, extrusion forming, or other means can be appropriately used. Furthermore, a backing material such as polyethylene foam or glass wool sheet may be attached to the back surface of the newly installed exterior material as necessary for reasons of preventing condensation, soundproofing, and fireproofing.

Moreover, the said heat insulating material has the protrusion part which can be temporarily attached by fitting to the fitting receiving part of the said exterior material in the water lower end as mentioned above.
The protrusion of the heat insulating material is not particularly limited as long as it can be fitted to the fitting receiving portion of the exterior material, but maintains a stable fitting state when fitted. For this purpose, it is preferable to provide a groove-like part adjacent to the projecting part, into which the underwater molding part of the side covering material can be inserted, as in the illustrated embodiment described later.
Such a heat insulating material is preferably a water-impermeable material or a material that has been subjected to water-impermeable treatment on at least the surface side, but is made of a synthetic resin such as foamed polystyrene or foamed polyethylene, or a known heat-insulating material such as glass wool board. It may be a single layer or a laminate. Moreover, you may give cosmetics, such as a glass fiber sheet, to the back surface of this heat insulating material as needed.

In addition, the holding member is a member that is arranged on the back surface side of the underwater molding portion of the side-laying exterior material as described above, and is used for attaching the side-laying exterior material to the existing roof in the mounting base or refurbishment.
As this holding member, for example, a high-strength aluminum extrusion mold material may be used, and a stainless steel plate or a plated steel plate usually having a thickness of about 0.6 to 3.2 mm depending on the size of the side covering material and the required strength. It may be formed by pressing or the like, and is not particularly limited.

First, in the first step, a protruding portion provided at the lower end of the heat insulating material is fitted and temporarily attached to the back surface side of the underwater molded portion of the side covering material.
As described above, the heat insulating material preferably has a groove-like portion adjacent to the protruding portion, but in this aspect, the protruding portion is fitted to the fitted receiving portion of the outer packaging material. At the same time, a stable fitting state can be maintained by inserting the underwater molded portion of the outer covering material into the groove-like portion.

Next, in the second step, the horizontal covering material temporarily attached with the heat insulating material in the first step is faced in an inclined manner, and the water-side molded portion is attached to the roof surface while rotating ( Engage with the underwater molded part of the front covering material.
The front side covering material is attached to the base by a holding member (hanger) as shown in the illustrated embodiment described later. However, the holding member does not interfere with the rotation in the process. Holds thatched exterior material.

Subsequently, in the third step, the lower end of the heat insulating material of the horizontal covering (attached to the step) attached in the second step is pressed and slid to the upper side of the water. A rotation space (of the side facing exterior material) in the next stage is provided on the back side of the underwater molding portion of the facing exterior material.
Immediately before the third step (that is, immediately after the second step), the heat insulating material of the side facing exterior material of the step is in contact with the mounting base (the existing roof in the renovation) in a mounting manner. In this state, even if pressed to the water side, the heat insulating material is not dropped, and can be stably slid along the mounting base (the existing roof in the repair).
The rotation space (of the side covering material) in the next stage is a space that allows the rotation in the second step, that is, the rotation for engagement, when the next side covering material is constructed. I mean.

Finally, the fourth step is engaged while rotating the holding member so as to be arranged on the back surface side of the underwater molding portion of the side facing exterior material (at the corresponding step) attached in the third step. Fix it to the roof surface in the state where
Immediately before the fourth step (that is, immediately after the third step), the heat insulating material temporarily attached to the horizontal covering material is slid to the water side, and the space in which the protruding portion of the heat insulating material is fitted ( Since the fitting receiving part) is opened, the upper end of the holding member can be fitted in the space. Note that the upper end of the holding member is a portion that engages with the fitting receiving portion of the horizontal covering material as described above, but the gobing portion of the next horizontal covering material is used as in the illustrated embodiment described later. It is desirable to also serve as a holding part for holding.

As described above, the method for constructing the horizontal roof of the present invention can be easily constructed regardless of whether the mounting base is a roof surface or an existing roof, and a beautiful exterior surface can be easily and safely. It can be constructed in a short time, and can be applied to new establishments and repairs. That is, since no adhesive is used to integrate the heat insulating material on the back surface of the exterior material, there is no need for adjustment or application work. In addition, since construction is performed from the upper side to the lower side of the flow gradient, workers will not step on, taint, or damage the existing side covering material, reducing scaffolding costs, shortening the construction period, and ensuring construction safety. Also improves.
In particular, when it is constructed so that the heat insulating material is disposed without a gap between adjacent holding members, the heat insulating layer continuous with the heat insulating material adjacent to the back surface side of the exterior surface (= heat insulating layer without heat insulating defect) Is formed.

  1 (a) to 1 (c), the construction method of the side roof of the first embodiment of the present invention uses the existing roof formed by laying the existing side roof material 6 as a mounting base. Each member shown in FIG. 2, the horizontal covering material 1, the heat insulating material 2, and the holding member 3 is used.

First, as shown in FIG. 2 (a), the lateral covering material 1 is formed by forming the water-side molded portion 12 by folding the edge of the substantially flat face plate portion 11 on the water-side (left side in the drawing). The water-side molded part 13 is formed by folding up the edge of the water-side (right side of the drawing), and the molded parts 12 and 13 are molded to engage with each other. On the back side, a metal forming plate is provided with a fitting receiving portion 14 that is a space in which the protruding portion 22 provided at the water lower end of the heat insulating material 2 can be fitted, and also provided with a rotation space for the horizontal covering material 1 in the next stage It is.
Next, as shown in FIG. 2 (c), the heat insulating material 2 has a groove-like portion 22 that opens to the lower side of the substantially rectangular main body portion 21, and on the surface side (upper side) thereof. The protruding portion 23 that can be temporarily attached by fitting to the fitting receiving portion 14 of the exterior material 1 is a backup material having a pressing portion 24 that protrudes longer than the protruding portion 23 on the back surface side (lower side).
Further, as shown in FIG. 2D, the holding member 3 has an engagement holding portion 31 whose front end is bent downward, and is fixed to an installation base (existing roof) to be fixed in a construction state. It is the aluminum extrusion material which has 32 and the vertical piece-shaped connection part 33 which connects them, and is shape | molded by a general C-shape.

  Briefly describing the existing roof, a rafter 5 continuous in the flow direction is disposed on the surface of the inclined base 4 via a waterproof sheet 4B, and the existing roof is installed by a plurality of hanging elements 7 attached to the rafter 5. A horizontal roofing material 6 is attached, and an existing heat insulating material 8 having a rectangular cross section is disposed on the back side of each horizontal roofing material 6 to form a stepped roof surface.

1st-4th process which forms the construction method (renovation method) of the horizontal roof of this invention based on Fig.1 (a)-(c), respectively is demonstrated.
First, as a first step, as shown in FIG. 1A, a protrusion 23 provided at the lower end of the heat insulating material 2 is fitted on the back surface side of the water-side molding portion 12 of the side-laying exterior material 1. Tentatively.
In this first embodiment, as described above, the groove-shaped portion 22 is formed adjacent to the protruding portion 23 of the heat insulating material 2, so that the protruding portion 23 is lined and the fitting receiving portion of the outer packaging material 1 is fitted. 14, and a stable fitting state was maintained by inserting the underwater molding portion 12 of the outer covering material 1 into the groove-like portion 22.

Next, as the second step, the side facing exterior material 1 temporarily attached with the heat insulating material 2 in the first step is faced in an inclined manner, and the water-side molded portion 13 is already roofed while rotating. It is made to engage with the underwater molding part 12 of the side facing exterior material 1 attached to the surface (front stage).
In addition, the front side covering material 1 of the front stage is already attached by the holding member 2 on the water upper side (right side) of the drawing.

Subsequently, as the third step, the bottom end (pressing portion 24) of the heat insulating material 2 of the side facing exterior material 1 attached in the second step is pressed and slid to the water side, and the side facing exterior material On the back surface side of the 1 water-side molding part 12, a rotation space for the horizontal covering material 1 in the next stage is provided.
Immediately before the third step (that is, immediately after the second step), the heat insulating material 2 temporarily attached to the side covering material 1 is in contact with the existing roof 6 so that it is placed in this state. Therefore, the heat insulating material 2 can be stably slid along the existing roof 6 without dropping the heat insulating material 2 even when pressed upward. Further, since the heat insulating material 2 is formed slightly longer than the arrangement interval between the adjacent holding members 3, 3, the water upper end of the slidable heat insulating material 2 comes into contact with the connecting portion 33 of the holding member 3. Just slide it up.
The rotation space of the horizontal covering material 1 in the next stage is a space that allows the rotation in the second step, that is, the rotation for engagement, when the next horizontal covering material 1 is constructed. I mean.

Finally, as a fourth step, the holding member 3 is rotated and engaged so as to be disposed on the back surface side of the water-side molding part 12 of the side covering material 1 attached in the third step. Fix to the roof surface in the state.
Immediately before the fourth step (that is, immediately after the third step), the heat insulating material 2 temporarily attached to the side covering material 1 is slid to the water side, and the protruding portion 24 of the heat insulating material 2 is fitted. Since the space (the fitting receiving portion 14) that has been opened is opened, the engagement holding portion 31 of the holding member 3 can be attached to the space 14 in an engaged state. At this time, the engagement holding portion 31 of the holding member 3 is engaged with the fitting receiving portion 14 of the side covering material 1, but the gouge portions 12 and 13 of the next side covering material 1. It also serves to hold

  Thus, the construction method (renovation method) of the side roof of the present invention can easily lay the side roof material 1 from the water side in the flow direction to the water side, and each of the first to fourth steps can be performed. It can be easily performed, and the operator does not step on, taint, or damage the side covering material 1 that has already been constructed, the scaffolding cost can be reduced, the construction period can be shortened, and the construction safety can be improved.

  In particular, in the first embodiment, since the heat insulating material 2 is formed slightly longer than the disposition interval between the adjacent holding members 3, 3, the heat insulating material 2 is constructed so as to be disposed without a gap. A heat insulating layer (= a heat insulating layer having no heat insulating defect) is formed continuously by the heat insulating materials 2 and 2 adjacent to the back surface side of the exterior surface.
