BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door attached to a general house or building, and more particularly to a heat insulating / soundproof door requiring soundproofing and heat insulating properties.

[0002]

2. Description of the Related Art In recent years, with the demand for comfort in living spaces, soundproofing and other measures have been emphasized in addition to cooling and heating all rooms. In order to realize such an indoor environment, it is important to save energy. In a general house, sound insulation and heat insulation occupy a large proportion. Therefore, in addition to the structure of the roof and the wall surface, in addition to the structure of the roof and the wall, attention has been paid to the structure of the heat insulating and soundproof door including the entrance door, and a material using a material that also functions as soundproofing has been proposed.

[0003] As an example of this kind of heat insulating / soundproof door, a plate-like body as a core material is provided in a space region formed by joining an outer edge of a rectangular frame and an outer edge on each inner surface side of a pair of front panels. The containment is known. In this plate-like body, a paper core made of aluminum hydroxide paper is arranged in the thickness direction, a large number of honeycomb-shaped air holes are formed, or a foam may be used. As a result, air can be held between the front panels, so that the doors have heat insulation properties and can block outside air and noise.

[0004]

[Problems to be Solved by the Invention] However, the above-mentioned conventional door is mainly made of foam or paper core.
Sufficient effects could not be obtained with respect to fire resistance and heat insulation. Therefore, there has been proposed a material in which glass wool having excellent heat resistance is used as a core material instead of the paper core, and the core material is sandwiched between the surface panels in a layered manner.

[0005] However, this door merely adheres the core material of glass wool to the inner surfaces of the pair of front panels, so that it is not possible to obtain sufficient rigidity as a heat-insulating / sound-proof door, and the right and left vertical force bones cannot be obtained. In addition to the frame consisting of upper and lower lateral force bones,
Additional reinforcement bone had to be added in the longitudinal and lateral directions.

[0006] Then, the weight of the entire door is increased, and the operation for opening and closing the door becomes heavy. In addition, since the reinforcing bone is located between the front panels and easily transmits sound, and also serves as a heat transfer material on the front and back surfaces, there remains a problem that the sound insulation function and the heat insulation effect of the heat insulation / soundproof door are reduced. The purpose of the present invention is to solve the above problems.

[0007]

In order to achieve the above object, the heat insulating / soundproof door of the present invention comprises a pair of upper and lower surfaces of a plate-like body in which fibers of a porous fiber material are arranged in the thickness direction. Characterized in that they are bonded to the inside of the surface panel.
The front panel may be a composite laminate, or a configuration in which the composite laminate is disposed on the inner surface of the front panel, and the plate-like body may be disposed in a hollow portion in the frame.

[0008]

The heat-insulating and sound-insulating door of the present invention comprises a plate-like porous fiber material in which a large number of fibers are arranged in a thickness direction, and a large number of fibers are provided between a pair of surface panels or composite laminates. Is formed. Since the minute gap is an air layer having a small volume, the heat insulating effect can be enhanced.
Further, the plate-like body is an aggregate of thin fibers, and each fiber vibrates when a sound wave collides with the surface panel, and converts sound energy into heat energy and absorbs it. Therefore, transmission of external noise to the inside is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the heat insulation and soundproof door. The heat insulation / soundproof door 1 is a single-opening door provided at the entrance of a house, an apartment, or the like, and a left side 1 a is rotatably attached to one side wall of the opening frame 3 by a hinge 13. Further, a locking device 2 including a knob and a cylinder key is provided at the center of the right side portion 1b. 14 is a mailbox.

As shown in FIG. 2, the opening frame 3 has recesses 4a and 5a by providing steps on the opposing surfaces of the left and right vertical frames 4 and 5, respectively. These grooves 4a, 5
Airtight rubber 6 for buffering which attenuates the shock when the heat insulation / soundproof door 1 is closed is fitted to each of a.

As shown in FIGS. 2 and 3, the heat insulating / soundproof door 1 has a structure in which a pair of front panels 8 and 9 are joined to a frame 7 and a plate 10 is used as a core material. A composite laminate may be used in place of the front panel, or a composite laminate may be provided on the inner surface of the front panel, and the plate 10 may be joined to the inner surface.

The frame 7 has a rectangular shape, and has lateral force bones 7a and 7b arranged vertically and longitudinal force bones 7c and 7d arranged left and right.
d is formed by joining the ends by welding. The left and right longitudinal force bones 7c and 7d have a U-shaped cross section as shown in FIG.
A pair of small holes is formed in each of the upper and lower portions. The inner surfaces 8a, 9a of the pair of front panels 8, 9 are respectively joined to both side surfaces of the longitudinal force bones 7c, 7d, and a hollow space is formed between the front panels 8, 9 and the frame body 7. A part is provided.

Each of the front panels 8 and 9 has both end edges turned back,
The respective tips 8b, 8c and 9b, 9c are fixed along the end faces of the left and right longitudinal force bones 7c, 7d by rivets 11 inserted into the small holes. A decorative cover 12 having a U-shaped cross section is joined to the tips 8b, 9b and 8c, 9c of the front panel by pressing and press-fitting, and the outer surface of the decorative cover 12 and the folded portion of the front panel are connected to each other. I'm one. An arm portion of the hinge 13 is fixed to an outer surface of the left decorative cover 12.

The plate 10 is made of a porous fiber material, such as rock wool or glass wool. This porous fiber material is formed by arranging a large number of thin fibers in the thickness direction and applying pressure to the fibers. The plate-like body may be formed by assembling a block formed by assembling a large number of fibrous materials and cutting the plate-like body under pressure while applying pressure. In addition, this plate-shaped body 10 is accommodated in the hollow part, and the surface panel 8,
The upper and lower surfaces 10a, 10b are bonded between the nine.

The assembling of the heat insulating / soundproof door 1 will be described. First, the inner surfaces 8a, 9 of the pair of front panels 8, 9 are described.
Apply adhesive to a. This adhesive is a urethane-based adhesive.
A liquid reaction type is used.

Next, one front panel 8 is placed on a table, and the frame 7 is placed on the front panel 8 and bonded. At this time, since both end edges of the front panel 8 are bent at a right angle, these serve as guides of the frame 7 so that each end face is properly positioned at both end edges of the front panel 8.

Subsequently, the plate-like body 10 is accommodated in an opening of a hollow portion formed by one of the front panel 8 and the frame 7, and the other front panel 9 is placed thereon. Then, the original shape of the heat insulating / soundproof door 1 is formed, and this is completed using a hot pressing press machine. In this case, when the adhesive is inserted into the heating part of the hot pressing press machine to heat the heat insulating and soundproof door 1 to cause a thermal reaction of the adhesive, the front panels 8 and 9 are cured.
The plate-like body 10 is firmly bonded. As a result, the entrance door 1 incorporating the porous fiber material in which the fine fibers are arranged in the thickness direction of the heat insulating / soundproof door 1 is manufactured.

Thus, the heat insulation / soundproof door 1 has improved heat insulation, fire resistance and soundproofing, and also has increased rigidity. That is, it is known that the smaller the volume of the air layer formed by partitioning the hollow portion is, the higher the heat insulating effect is. In this example, since a large number of fine filament fibers made of rock wool or glass wool are aggregated, a large number of air layers that are minute gaps are formed,
The heat insulating property is remarkably improved as compared with a paper core made of aluminum hydroxide paper arranged in a honeycomb shape as in the related art.

Regarding fire resistance, when the porous fiber material is made of rock wool, the porous fiber material is made of a mineral substance and maintains its original shape without melting even when exposed to high heat. As for soundproofing, when a sound wave collides with the door 1, the linear fibers aligned in the thickness direction vibrate, and convert sound energy into heat energy and absorb it. Conventional core materials such as paper cores and foams do not have such an effect. According to the porous fiber material of this example, the sound generated outside the door 1 can be reduced and transmitted to the room. Is greatly suppressed.

Further, since a large number of fibers are formed in a plate shape and firmly adhered while being sandwiched between the front panels 8 and 9, the rigidity is increased and the strength of the door 1 is increased. For example, good results were obtained for tests such as tensile load and torsion when compared with conventional doors.

[0021]

[Effects of the Invention] As described above, the heat insulating and soundproof door of the present invention has the upper and lower surfaces of a plate-like body in which each fiber of the porous fiber material is arranged in the thickness direction, and is placed inside a pair of front panels. Since they are adhered to each other, a large number of air layers, which are minute gaps, are formed in the plate-like body, and the heat insulating property is remarkably improved as compared with the conventional heat insulating and soundproof door.

Further, the plate-like body is formed by assembling a large number of fine fibers. When a sound wave collides with the surface panel, the fibers vibrate and convert sound energy into heat energy and absorb it. External noise and the like can be significantly reduced. Further, since the plate-like body is sandwiched and adhered to the front panel, the rigidity is increased, and the strength of the heat insulating / soundproof door is increased.
