Description

The present invention is installed between a lower folded plate roof and an upper folded plate roof in a two-layer type folded plate roof, increases the distance between the lower folded plate roof and the upper folded plate roof in the height direction, and It relates to a heat insulating support for construction and a two-story folded plate roof having a function of preventing a fall.

Conventionally, there are many two-layer type roofs including a lower-layer folded plate roof and an upper-layer folded plate roof. These roofs include a new two-story type roof (or wall) and a renovated roof with a new roof added to the existing roof (including the wall). The lower folded plate roof is constructed with a metal folded plate type roof plate material.

In this type of roof, it is composed of a folded plate roof plate material having a lower plate portion and an upper plate portion, and the lower plate portion and the upper plate portion of the adjacent folded plate roof plate materials are fastened to each other to form a folded plate roof. There are some that connect the plate materials to each other to construct a folded plate roof or the like. A support is provided between the upper folded plate roof and the lower folded plate roof, and the support is mounted on the lower folded plate roof, and the upper folded plate roof is placed on the lower folded plate roof by the support. It is supported. As a heat insulating method for folded-plate roofs, double-folded-plate roofs are currently the mainstream. However, as a result of recent weather conditions and strengthening of measures against global warming and energy saving measures, there is an increasing demand for high heat insulation performance of double-folded plate roofs or higher even for metal roofs, depending on the use of the building.

The current countermeasures for a folded plate roof system having a high insulation specification of a double folded plate roof (insulation layer H100 mm) or more are as follows. First of all, make a triple folded plate roof. Secondly, in addition to the double-folded roof, a heat-insulated ceiling system should be used. Thirdly, in addition to the double-folded plate roof, the folded plate is backed. However, these countermeasures are not as effective as the cost, and also impair the light weight (seismic performance), which is an advantage of the metal roof.

Are arranged and fixed at predetermined intervals on a structural material 100 such as a main building and a furring strip, and a plurality of folded plate roof plate materials 71, 71, ... Are arranged side by side via the metal fittings 200. Then, the lower plate 71d and the upper plate 71e of the adjacent folded plate roof plate materials 71 and 71 are fastened together and connected to construct a roof or a wall (see FIG. 1).

Next, as shown in FIGS. 1 and 2 (A), the upper folded plate roof B2 has the same configuration as the lower folded plate roof B1, and the same folded plate roof plate materials 72, 72, ... Are used. The roof. The folded plate roof plate materials 72, 72, ... Have the same or substantially the same structure as the folded plate roof plate material 71 constituting the lower folded plate roof B1. That is, the rising side portions 72b and 72b are formed from both sides of the main plate 72a in the width direction.

Upper pieces 72c, 72c that are substantially flat are formed at the upper ends of the rising side portions 72b, 72b. The upper piece portion 72c is inclined outward and upward at a slight angle.

A heat insulating material 91 is provided between the lower folded plate roof B1 and the upper folded plate roof B2 in the two-layer folded plate roof B. The heat insulating material 91 is made of glass wool or the like and is formed in a futon shape. In the present invention, in order to fill a larger amount of the heat insulating material 91 than the normal two-layer heat insulating roof, the distance between the lower folded plate roof B1 and the upper folded plate roof B2 in the height direction is increased. Therefore, the height of the heat insulating support A for construction is set according to the height thereof. The distance in the height direction of a normal two-story folded plate roof is about 100 mm. In the present invention, the height is at least about 1.5 times higher than usual and about twice as high. In a normal two-layer folded plate roof, the futon-shaped heat insulating material has one layer, but in the present invention, it has two layers [see FIG. 1 (A)].

Therefore, the overall height of the building insulation support A in the present invention is about 200 mm. As the overall height of the heat insulating support A for construction increases, a gap occurs between the lower folded plate roof B1 and the upper folded plate roof B2 during thermal expansion and contraction of the two-layer folded plate roof B, and the upper folded plate roof B2 tends to fall. The fall prevention portions 52 and 52 of the sandwiching plate material 5 attached to the heat insulating support A prevent or prevent the building heat insulating support A from falling in the front-rear direction.

The distance in the height direction of a normal two-story folded plate roof is about 100 mm. In the present invention, the height is at least about 1.5 times or more the normal height, and the height is about twice as high, specifically about 200 m. In a normal two-layer folded plate roof, the futon-shaped heat insulating material 9 is usually made up of one layer, whereas in the present invention, it is made up of two layers [see FIG. 1 (A)]. FIG. 7 shows an embodiment in which the space between the lower folded plate roof B1 and the upper folded plate roof B2 of the two-layer folded plate roof B is further widened to form the heat insulating material 91 as three layers. In this embodiment, the height dimension of the first holding member 1 and the second holding member 2 constituting the building heat insulating support A is set to be higher than usual [see FIG. 7B]. .. In this way, by setting the height of the heat insulating support A for construction to be even higher, it is sufficiently possible to make the heat insulating material 91 into four or more layers.

Further, in the present invention, one folded plate roof may be added to the two-layer folded plate roof B to form a three-layer folded plate roof [see FIG. 8 (A)]. In this case, a middle-layer folded-plate roof B3 exists between the lower-layer folded-plate roof B1 and the upper-layer folded-plate roof B2, forming a three-layer folded-plate roof. Lower folded plate roof B1 and middle folded plate roof B3
The height spacing of the middle-layer folded plate roof B3 and the height direction spacing of the upper folded plate roof B2 are basically the same. In addition, the positions of the fastening portions J of the lower folded plate roof B1, the middle folding plate roof B3, and the upper folding plate roof B2 are all the same (including substantially matching), and the fastening portions J are aligned in the upper, middle, and lower parts. Two upper and lower heat insulating supports A for construction are used at the location [see FIG. 8 (A)].

Next, the sandwiching plate member 5 is configured as two independent members, the fall prevention plate member 5A and the connecting plate member 5B, and there is an embodiment (see FIG. 9). In this embodiment, the fall prevention plate member 5A has a substantially rectangular shape, the central portion in the front-rear direction thereof is the central support portion 51, and the fall prevention plates 52 and 52 are present on both sides in the front-rear direction.

The lower ends of both fall prevention portions 52 and 52 and both sides in the front-rear direction are provided with holding pieces 521 and 521 [see FIG. 9 (A)]. Further, the fall prevention plate member 5A has fixing through holes 51a, 51a, ... For being fixed between the first holding member 1 and the second holding member 2 by the fastener 3. [See FIG. 9 (A)]. Specifically, the fall prevention plate member 5A and the connecting plate member 5B have two fixing through holes 51a and 51a, respectively.

Further, the fixing through hole 16 of the first holding member 1 and the fixing through hole 26 of the second holding member 2 corresponding to this embodiment are each four, and two fixing through holes located on the lower side are used. The through holes 16 and 26 are dedicated to the fall prevention plate member 5A, and the two fixing through holes 16 and 26 located on the upper side are dedicated to the connecting plate member 5B [see FIGS. 9A and 9B). ].

The connecting plate member 5B has a substantially rectangular shape like the fall prevention plate member 5A, and the central portion in the front-rear direction thereof is the central support portion 51, and the connecting arms on both sides in the front-rear direction, the upper end thereof, and both sides in the front-rear direction. The shape portions 53 and 53 are present. Locking portions 53a and 53a for locking the connecting member 54 are provided at the upper ends of both connecting arm-shaped portions 53 and 53 [see FIG. 9A].

See FIG. 9 (A)].

The sandwiching plate material 5 is configured to include two independent members, a fall prevention plate member 5A and a connecting plate member 5B, which are independent of each other. Can be used. First, both of these two members can be used, or only one of them can be used. Therefore, if only the purpose of preventing the building insulation support A from falling in the front-rear direction is sufficient, it is possible to use only the fall prevention plate member 5A.

In addition, the building insulation support A can be prevented from collapsing in the width direction, and the upper folding plate roof B2 of the two-layer folded plate roof B can be supported from the lower surface by the building insulation support A so that the upper folded plate roof B2 is covered. For the purpose of allowing the worker to walk with peace of mind, it is possible by using the connecting plate member 5B and the connecting member 54.

Further, by using both the fall prevention plate member 5A and the connecting plate member 5B, it is possible to prevent or suppress the fall of the building heat insulating support A in the front-rear direction and the width direction. Further, it can be used according to the type of the folded plate roof plate material 71 of the lower folded plate roof B1 and the folded plate roof plate material 72 of the upper folded plate roof B2 due to the difference in size in the height direction.

In this way, the use of building insulation supports can be diverse. At this time, the number of the fixing through holes 16 of the first holding member 1 and the fixing through holes 26 of the second holding member 2 is 4 or more, preferably 5 or more, so that the building heat insulating support A can be used. The mounting positions of the mounted fall prevention plate member 5A and the connecting plate member 5B in the height direction can be adjusted, and the sizes of the folded plate roof plate material 71 of the lower folded plate roof B1 and the folded plate roof plate material 72 of the upper roof B2 vary. Can be used.

Further, if the structure is such that the lower end of the fall prevention plate member 5A can be prevented from falling by simply contacting the lower end of the fall prevention plate member 5A on the tightening portion J, the lower end side of the rectangle is simply processed for the holding piece 521. It can be used as a vertical plate as it is. Therefore, the connecting plate member 5B can be used as it is as the fall prevention plate member 5A. In this case, the fall prevention plate member 5A and the connecting plate member 5B have substantially the same shape, and only one type of mold is required to manufacture them, which has an advantage that the manufacturing cost can be remarkably reduced.

Next, in the building heat insulating support A, there is an embodiment in which the cushion material 92 is provided on the pedestal portion 15, 25 and the lower surface of the fall prevention portion 52, and the cushioning piece 521 [see FIG. 4 (E)]. The cushion material 92 is in the form of a sheet, and rubber, a soft synthetic resin, or the like is used. The cushion material 92 is attached to the pedestals 15 and 25 of the building heat insulating support A and the sill holding piece 521 on the lower surface of the fall prevention portion 52 with an adhesive, adhesive tape, or the like. Alternatively, when the building heat insulating support A is installed on the lower folded plate roof B1, the pedestals 15, 25 of the building heat insulating support A, the sill holding piece 521 on the lower surface of the fall prevention portion 52, and the lower folded plate roof B1 The cushion material 92 may be arranged between the and.
