Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a base member for a horizontal roof that is laid on a main roof.

[Conventional technology]

Conventionally, as shown in Utility Model Application Publication No. 56-155028,
A large number of lower layer materials are laid closely together in the vertical direction (direction of the eave ridge) and horizontal direction (left and right direction perpendicular to the direction of the eave ridge) on the main roof, and rafters are supported and fixed on the lower layer materials. A horizontal roof was constructed by supporting and laying a base material between the rafters, and covering the rafters and the base material with long metal roofing sheets.

In addition, as shown in Utility Model Application Publication No. 54-114424,
There was a base plate member in which a back-up material having an upper surface shape of continuous right triangles in the vertical direction was integrally provided on the base material.

[Problem that the invention attempts to solve]

However, if the aforementioned conventional base plate members are used on the aforementioned conventional roof, the lower layer materials are laid on the main roof, the rafters are supported and fixed on top of these materials, and then the lower layer materials are supported on these rafters and lowered between the rafters. Since the base plate member is laid, the lower layer material and the base plate member must be laid in two parts at the roof construction site, which is not efficient. In addition, in conventional base plate members, the upper surface of the backup material provided on the base material is shaped like a series of right triangles in the vertical direction (direction of the eave ridge), so the vertically adjacent metal roof plate If the back-up material is made of a material with low strength such as styrofoam, a large amount of force will be concentrated and damaged when joining the roof sheets, and the back-up material may be damaged. There was a problem in that there was little freedom in selecting the materials for the backup materials, and they tend to be expensive.

The present invention solves the above-mentioned problems, allows for easy installation at roof construction sites, and allows the use of low-strength and inexpensive materials as back-up materials.
Furthermore, it is an object of the present invention to provide a base plate member for a horizontal roof that is relatively inexpensive as a whole.

[Means for solving problems]

The base plate member for a horizontal roof of the present invention is such that the lower layer material laid on the main roof is made of a material with heat insulating properties, and a plurality of base materials are laterally arranged in parallel on the lower layer material. A rafter installation interval is formed in between, and a rafter support part is formed on both side edges of the underlayer material to protrude laterally outward of the underlayment material with a width of 1/2 of the width of the rafter installation interval, and A plurality of backup materials having heat insulation and soundproofing properties and having a right triangular cross section with a high eave side are arranged in parallel in the vertical direction, and spaces for roof plate joints are formed between these backup materials, A support part for the roof plate joint part is formed on the ridge side end of the base material and protrudes from the ridge side of the back up material at the ridge side end with the same width as the spacing for the roof plate joint part, and further the lower layer material and the base material It is an integrated product of back up material and back up material.

[Effect]

The base plate member for horizontal roofs according to the present invention integrates the lower layer material, the base material, and the backup material, so at the roof construction site, the lower layer material can be used vertically or vertically.
It is sufficient to lay a large number of materials on the main roof in close contact with each other in both horizontal directions.
The cables can be laid in one go, and these can be laid with good work efficiency. In addition, a spacing for the roof plate joints is provided between the plurality of backup materials provided on the base material, and
A support part for the roof plate joint without backup material is provided at the eave side end of the base material, and the metal roof plate is joined on the joint spacing and joint support part. Because large forces are not concentrated on the backup material during work such as joining roof panels, it is possible to use materials such as polystyrene foam, which is inexpensive, has good heat insulation and soundproofing properties, but has low strength. can be used. Then, all you have to do is integrate the lower layer material, base material, and backup material at the factory, and because there is a large degree of freedom in selecting these materials, it is possible to obtain base plate members with excellent heat insulation properties using inexpensive materials. can.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In Figures 1 and 2, reference numeral 1 indicates a base material made of a rectangular planar wood wool board, Century Board (trade name), etc., 2 is a back-up material made of a foam such as polystyrene;
A plurality of these are fixed to the upper surface of the base material 1 with adhesive in the longitudinal direction along the vertical direction (eave ridge direction) at a predetermined interval 3 for the roof plate joint, and the back up material 2
Each of the base materials 1 is formed in a right triangular cross-section along the vertical direction with a high height toward the eaves. At the ridge-side end of the base material 1, a support portion 3a for a roof plate joint portion is formed which protrudes toward the ridge side of the back-up material 2 at the ridge-side end.
The width of this joint support part 3a is the same as the width of the roof plate joint interval 3. Further, the width of the back-up material 2 is formed to correspond to the width of the face plate excluding the engaging portion of the metal roof plate, which will be described later.

A plurality of base materials 1 are fixed with adhesive on a lower layer material 4 made of a plate-shaped heat insulating material at intervals 5 for installing rafters, and on both sides of the lower layer material 4 there are 1/1/2 of the interval 5 for installing rafters.
A rafter support portion 5a having two widths and no base material 1 is formed. Furthermore, the lower layer material 4, the base material 1, and the backup material 2 are integrated, and a base plate member 6 for a horizontal roof is constituted by these.

Then, as shown in Figures 3 and 4, the main building 7
The lower layer material 4 is positioned and supported on top, and is fixed to the main building 7 with fixing tools 9 such as nails, and a large number of the plate members 6 bring these lower layer materials 4 into close contact with each other.
It can be laid both vertically and horizontally without any gaps. A wooden rafter 8 is fitted between the base material 1 of the base plate member 6 using the rafter installation interval 5 and the rafter support portions 5a on both sides of the base material. The rafters 8 are supported on the lower layer material 4 and are fixed on the main building 7 through the lower layer material 4 with fixing tools 9 such as nails passing through the lower layer material 4 so as to be perpendicular thereto. Further, the roof plate 10 is formed by bending and forming a metal plate to form a face plate 10a having a width dimension and a cross-sectional shape corresponding to the width dimension and shape of the backup material 2.
Ridge-side and eaves-side engaging portions 10b and 10c are provided on both sides. One roof plate 10 is used for each backing material 2 arranged in the direction of the eaves,
The inner surface of the face plate 10a is closely aligned with the rafters 8 and the backup material 2, and the roof plate 10 is placed on the plural base plate members 6 so as to be perpendicular to the longitudinal direction thereof.
These are horizontally roofed as they are being passed over.

In this case, the roof panels 10 are fixed to the rafters 8 using locking devices (not shown) called hangers, and the roof panels 10 adjacent to each other in the direction of the eaves are connected to the roof panels of the backup material 2. At the interval 3 for the part and the support part 3a for the roof plate joint part, the ridge side and eave side engaging parts 10b,
This is done by a conventionally known means of engaging 0c.

The eaves and ridges of the roof will be treated in the same manner as conventional roofs. In Figure 4,
11 is the arabesque at the eaves.

In the base plate member 6 of the above-described embodiment, a backup material 2 made of foam is fixed on a base material 1 in advance at a factory, and the base material 1 is fixed to a lower layer material 4. Then, at the construction site, the lower layer material 4 of the base plate member 6 is positioned and fixed on the main building 7 with close contact in both vertical and horizontal directions, and the rafter installation interval 5 between the base materials 1 and the rafter support part 5a are used to install the base material 4. Since it is only necessary to fix the rafters 8 between the materials 1, the base material 1, backup materials 2, and rafters 8 can be easily and with less effort, and the mounting position of the roof board 10 can be adjusted by laying the base material 6. Coupled with this, work efficiency is improved.

Furthermore, the base plate member 6 is arranged in the vertical direction (in the direction of the eave ridge)
A plurality of pieces are butted against each other at the ends and laid between the main buildings 7, but if there is an irregularity during laying, the 7th
As shown in the figure, a plate member 6 of all shapes and sizes can be cut in half in the longitudinal direction to form a plate member 6a, or cut into 1/3 to form a plate member 6b,
The plate member 6c can be made smaller and used by reducing the size to 1/6.

The base plate member of the present invention, as shown in FIG.
The lower layer material 4 is laid on the main building 7, and the metal rafters 16 having a hat-shaped cross section are inverted and fitted between the base materials 1 at the rafter installation intervals 5 and the rafter support portions 9 of the base material 1, and the above-mentioned The flange portions 16a of the rafters 16 may be supported on both sides of the base material 1.

Further, in the present invention, as illustrated in FIG. 5, the width of the backup material 2 fixed to the base material 1,
The spacing 3 and number of rafters can be changed as appropriate depending on the width of the roof board.

[Effects of the invention] As explained above, in the horizontal roof base member of the present invention, the lower layer material laid on the main roof is made of a heat-insulating material, and a plurality of base materials are laid horizontally on the lower layer material. A rafter installation interval is formed between these base materials, and 1/2 of the width of the rafter installation interval is formed on both side edges of the base material on the outside of the base material in the lateral direction.
A plurality of back-up materials having a right triangular cross-section with high eaves sides and having thermal and sound-insulating properties are arranged vertically in parallel on the base material to form rafter support parts that protrude in width. A roof plate joint space is formed between the materials, and a roof plate joint space that protrudes from the ridge side end of the base material to the ridge side of the back-up material at the ridge side end with the same width as the roof board joint space. Since the supporting portion is formed and the lower layer material, base material and backup material are integrated, the following effects can be obtained.

In other words, since the base plate member for horizontal roofs according to the present invention integrates the lower layer material, base material, and backup material, the lower layer materials can be brought into close contact both vertically and horizontally at the roof construction site. It is only necessary to lay a large number of them on the main roof, and the lower layer material, base material, and backup material can be laid at one time, and these can be laid with good workability. In addition, an interval for a roof plate joint is provided between a plurality of back-up materials provided on the base material, and a support portion for the roof plate joint without a backup material is provided at the ridge side end of the base material, and the Since the metal roof panels are joined at the spacing between the sections and on the support sections for the joints, large forces are not concentrated on the back-up materials when joining these roof panels, thereby reducing back-up. As the material, a material such as expanded polystyrene which is inexpensive, has good heat insulation and soundproof properties, but has low strength can be used. All that is required is to integrate the lower layer material, base material, and backup material at the factory, and because there is a large degree of freedom in selecting these materials, it is possible to obtain base plate members with excellent heat insulation properties using inexpensive materials. can.
