Description

[Detailed explanation of the invention] This design creates a space between the base material laid on the main roof and the field material supported by the step part of the support material, thereby blocking outdoor noise and noise, as well as having a heat insulation effect. The aim is to provide roofs for tall buildings.

As is well known, the roof of a typical house is constructed by installing rafters at appropriate intervals above the main building, sloping downward toward the eaves.
A field material is laid on the rafters, a waterproof sheet material is attached to the upper side of the field material, and a metal roof plate is secured to the surface of the waterproof sheet material.

However, with the above-mentioned roof, the sound insulation effect is negligible because, for example, the sound of rain during rain and outdoor noise directly affect the inside of the room.

Furthermore, since thicker insulation materials must be used to increase the insulation effect, the construction cost increases significantly. Also, as in Japanese Patent Application Laid-open No. 53-30127, roofs with an air layer between the roof board and the shedding board are known, but since the upper surface of the air layer is only the roof board, it does not have a sufficient sound insulation effect. and insulation effect cannot be expected.

This proposal has been devised in view of the above, and below, the present proposal will be explained with reference to examples of drawings regarding the roof of a wooden house. 1 is a base material made of a material that has a sound absorbing function and is fixed to the main building 3 of the house 2. , the base material 1
The board is made of, for example, a relatively soft wood wool board that also has a heat insulating function, and is spread over the top surface of the main building 3 and fixed at appropriate intervals by, for example, nailing.

Reference numeral 4 denotes a plurality of elongated metal supports arranged in multiple rows at appropriate intervals on the upper surface of the base material 1, and are arranged in a downward slope from the ridge toward the eaves. This support material 4
It has a step shape consisting of a wide portion 5 and a narrow portion 6 protruding from the upper surface of the wide portion 5, and step portions 7 extending in the length direction are provided on both sides.

A mounting piece 8 extending outward is provided on the lower edge of the wide portion 5.

In order to fix the supporting material 4 described above to the base material 1, for example, attach a bolt rod whose lower end is fixed to the main building 3 to the base material 1.
It passes through the supporting material 4 from above and fastens the upper surface of the supporting material 4 with a nut screwed from the upper end.

In this way, by tightening each support material at appropriate intervals along the length direction, the support material 4 is firmly fixed to the surface of the base material 1.

In each of the several supporting members 4 arranged in this manner, field material 9 is laid between adjacent supporting members 4, 4.

This field material 9 is a relatively hard material made of pulp cement board or other material, and has a thickness approximately equal to the height of the top surface of the step part 7 and the top surface of the support material 4, so it has sufficient sound insulation and heat insulation functions. have

In order to lay this field material 9 between the supporting materials 4, 4, the left and right side edges of the field material 9 are connected to the stepped portions 7 of each supporting material 4.
When the field material 9 is supported in this way, a space 10 having the height of the wide portion 5 is formed between the upper surface of the base material 1 and the bottom surface of the field material 9. Ru.

For example, to fix the Naono material 9 to the support material 4,
A screw driven from the top surface of the field material 9 may be screwed into a tapping hole formed in the stepped portion 7, or
A protruding notched claw piece may be driven into the lower surface of the field material 9 from below.

The space 10 constructed by laying the field material 9 between the supporting materials 4 and 4 in this way becomes an air layer, so the insulation effect is significantly increased, and especially if the space is communicated with the atmosphere at the eaves and ridge In this case, since the atmosphere flows, the insulation effect can be further enhanced.

Further, even if this space 10 is filled with glass wool or the like, a sufficient heat insulation effect can be expected.

After the shedding material 9 is laid between the supporting materials 4 as described above, the upper surface of the shedding material 9 is laterally covered with a horizontally elongated roofing material 11, but the roofing material 11 is arranged orthogonally to the supporting material 4. Then, it can be fixed to the top surface of the support material using a hanger, screws, nails, etc.

In this way, according to the present invention, indoor sounds (for example, noises from pianos, records, etc.) are absorbed by the base material and blocked by the field material, so they do not leak outside. Noise and the sound of rainwater hitting the roof panels are blocked by the base material and shedding material and do not reach the interior. Therefore, the sound insulation effect between indoors and outdoors is extremely good, resulting in a comfortable building that is easy to live in. Furthermore, there is a base material below the space,
Since there is field material above the space at a height that is approximately equal to the height of the stepped part of the support material and the top surface of the support material, the solar heat irradiating the roof board is blocked by the field material and the space.
In addition, indoor heat is not released to the outside due to the base material and the space. Therefore, the insulation effect of the roof is extremely good, resulting in a room that is cool in the summer and warm in the winter.

In addition, since there is field material on the bottom of the roof, it is extremely strong against loads from the top, and even if a worker stands on the top of the roof during roof construction or repair, it will not dent or get damaged, and it can withstand heavy snowfall. It can withstand quite a lot. Therefore, the building can withstand long-term use and has great practical value.

[Scope of utility model registration request] A base material with sound-absorbing and heat-insulating functions is densely laid on the main roof, and on top of the base material, a large number of supporting members with steps formed in the middle of the height of the left and right sides are installed in parallel. Field material with a thickness that is approximately equal to the height of the top surface of the step and the top surface of the support material and has sound insulation and heat insulation functions is laid between adjacent support materials, and the bottom surface of the side edge of the field material is By supporting the top surface of the base material and forming a space between the top surface of the base material and the bottom surface of the field material, and by fixing the roofing board on the top surface of the field material to the top surface of the support material, the sound insulation and heat insulation functions are significantly improved. The roof of a building has been improved.
