Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door attached to a general house or a building, and more particularly to a heat insulating / soundproof door that requires soundproofing and heat insulating properties.

[0002]

[Prior Art]

 In recent years, along with the demand for comfort in the living space, it has been emphasized that all rooms are cooled and heated, and soundproofing measures are taken. In order to realize such an indoor environment, it is important to save energy, and sound insulation and heat insulation occupy a large part of the weight of ordinary houses. Therefore, in addition to the structure of the roof and wall surfaces, the structure of the heat insulating / soundproof door including the entrance door is attracting attention as a soundproofing and heat insulating measure, and a material using also a soundproofing is proposed.

As an example of this kind of heat insulating / soundproof door, a plate-like body is used as a core material in a space area formed by joining an outer edge of a rectangular frame and outer edges of inner surfaces of a pair of front panels. The one contained is known. This plate-like body may have a paper core made of aluminum hydroxide paper aligned in the thickness direction to form a number of honeycomb-shaped air holes, or may use a foam. As a result, air can be retained between the front panels, so that the door can be insulated so that the outside air and noise can be shielded.

[0004]

[Problems to be solved by the device]

 However, when the foam or the paper core is used as a main material, the conventional door cannot obtain sufficient effects in terms of fire resistance and heat insulation. Therefore, there has been proposed a method in which glass wool having excellent heat resistance is used as a core material instead of the above-mentioned paper core and the layers are sandwiched and bonded between the surface panels.

However, since this door is formed by only adhering the glass wool core material to each inner surface of the pair of surface panels, it is not possible to obtain sufficient rigidity as a heat insulating / soundproof door, and the left and right vertical strength bones are not formed. In addition to the frame consisting of upper and lower lateral strength bones, reinforcement strength bones had to be added in the longitudinal and lateral directions.

As a result, the weight of the entire door is increased, which causes a problem that the operation of opening and closing the door becomes heavy. In addition, the reinforcing ribs are located between the front panels and can easily transmit sound, and also serve as a heat transfer material on the front and back surfaces, so that there remains a problem that the sound insulation and sound insulation of the door are reduced and the heat insulation effect is reduced. The present invention aims to solve the above problems.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the heat insulating / soundproof door of the present invention has an upper and lower surface of a plate-shaped body in which each fiber of the porous fiber material is arranged in the thickness direction, inside the pair of surface panels, respectively. Characterized by being bonded. The surface panel may be a composite laminated plate, or the composite laminated plate may be arranged on the inner surface of the surface panel, and the plate-shaped body may be arranged in a hollow portion in the frame body.

[0008]

[Action]

 The heat insulating / soundproof door of the present invention is a plate-like porous fiber material in which a large number of fibers are arranged in the thickness direction, and a large number of minute gaps are provided between a pair of surface panels or a composite laminated plate. 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 when a sound wave collides with the surface panel, each fiber vibrates, and the sound energy is converted into heat energy and absorbed. Therefore, the transmission of external noise to the inside is reduced.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a heat insulating / soundproof door. This heat insulating / soundproof door 1 is a single-opening type entrance door provided at the entrance of a house or a mansion, and the left side portion 1a is rotatably attached to one side wall of the opening frame 3 by a hinge 13. .. 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 mail box.

As shown in FIG. 2, the opening frame 3 is provided with stepped portions on opposing surfaces of the left and right vertical frames 4 and 5 to form recessed grooves 4a and 5a. An airtight rubber 6 for cushioning is provided in each of the recessed grooves 4a and 5a for cushioning a shock when the heat insulating / soundproof door 1 is closed.

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 laminated plate may be used instead of the front panel, and the composite laminated plate may be arranged on the inner surface of the front panel and the plate 10 may be bonded to the inner surface.

The frame 7 has a rectangular shape and is formed by arranging lateral force bones 7a and 7b in the upper and lower sides and longitudinal force bones 7c and 7d in the left and right sides, and joining the end portions of the respective force bones 7a to 7d by welding. It As shown in FIG. 2, the left and right vertical force bones 7c and 7d have a U-shaped cross section, and two pairs of small holes are formed in each of the upper and lower portions. The inner side surfaces 8a and 9a of the pair of surface panels 8 and 9 are joined to both side surfaces of each longitudinal force bone 7c and 7d, respectively, and between the surface panels 8 and 9 and the frame body 7 described above. Is provided with a hollow portion.

Each front panel 8 and 9 has its both ends folded back, and the tips 8b, 8c and 9b and 9c are inserted into the small holes along the end faces of the left and right vertical force bones 7c and 7d. It is fixed by the belt 11. A decorative cover 12 having a U-shaped cross section is joined to the front ends 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-back portion of the front panel are bonded to each other. I'm one. The arm portion of the hinge 13 is fixed to the outer surface of the left-side decorative cover 12.

The plate-shaped body 10 is made of a porous fiber material, and rock wool or glass wool is used as the fiber material. This porous fiber material is made by arranging a large number of thin fibers in the thickness direction and applying pressure to make them dense. The plate-like body may be formed by collecting a large number of fibrous materials, forming a block obtained by cutting the fibrous material into the thickness of the plate-like body under pressure, and collecting the blocks. The plate-shaped body 10 is housed in the hollow space, and the upper and lower surfaces 10a and 10b are bonded between the front panels 8 and 9.

The assembly of the heat insulating / soundproof door 1 will be described. First, an adhesive is applied to the inner side surfaces 8a, 9a of the pair of front panels 8, 9. This adhesive is a urethane type two-liquid reaction type.

Next, one surface panel 8 is placed on the table, and the frame 7 is placed on the surface panel 8 and bonded. At this time, since both end edges of the front panel 8 are bent at a right angle, this serves as a guide for the frame body 7, and each end surface is properly positioned at both end edges of the front panel 8.

Subsequently, the plate-like body 10 is housed in the opening of the hollow portion formed by the one surface panel 8 and the frame body 7, and the other surface panel 9 is placed on this. Then, the original shape of the heat insulating / soundproof door 1 is constructed, and this is completed by using a heat press machine. In this case, when the adhesive is thermally reacted by inserting it into the heating part of the hot pressing machine and heating the heat insulating / soundproof door 1, the plate-shaped body 10 is firmly fixed to the front panel 8 or 9 by curing. To be glued. As a result, the entrance door 1 including the porous fiber material in which the fine-fiber-shaped fibers are aligned 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 sound insulation, as well as rigidity. That is, regarding heat insulation, it is known that the smaller the volume of the air layer formed by partitioning the hollow portion, the higher the heat insulation effect. 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 gaps, which are minute gaps, are formed, and a paper core made of aluminum hydroxide paper is used in the honeycomb as in the past. The heat insulation is significantly improved compared to the ones arranged in a shape.

Regarding the fire resistance, when rock wool is used as the porous fiber material, since it is made of a mineral substance, even if it is exposed to high heat, the original shape is maintained without melting. As for soundproofing, when a sound wave collides with the door 1, the linear fibers arranged in the thickness direction vibrate, and the sound energy is converted into heat energy and absorbed. Conventional core materials such as paper cores and foams do not have such an effect, and the porous fiber material of this example can reduce the sound generated outside the door 1 Transmission is greatly suppressed.

Furthermore, since a large number of fibers are formed into a plate shape and firmly bonded to each other 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, when tests such as tensile load and twist were compared with conventional doors, good results were obtained.

[0021]

[Effect of the device]

 As described above, in the heat insulating / soundproof door of the present invention, the upper and lower surfaces of the plate-like body in which the fibers of the porous fiber material are arranged in the thickness direction are bonded to the insides of the pair of front panels, respectively. A large number of air gaps, which are minute gaps, are formed in the plate-shaped body, and the heat insulation properties are significantly improved compared to conventional heat insulation and soundproof doors.

In addition, the plate-shaped body is an assembly of many thin fibers, and when a sound wave collides with the surface panel, the fibers vibrate and convert sound energy into heat energy, which is absorbed. It is possible to significantly reduce external noise and the like. Furthermore, since the plate-shaped body is sandwiched and adhered to the front panel, the rigidity is increased and the strength of the heat insulation / soundproof door is increased.
