Description

[Detailed description of the invention] This invention relates to an airtight and soundproof structure for doors, etc., and more specifically, mainly for existing general doors, especially general outward-opening sash doors using extruded aluminum. A frame and
To improve the airtight and soundproof structure of doors, etc., in which the contact point with the door frame, which is provided inside the frame so that it can be opened and closed, and the void in the vicinity are soundproofed by airtight members of a desired shape. This is related.

In the case of this type of door that has been commonly used in the past, the frame body consists of an upper frame, a lower frame, and left and right vertical frames, and the inner circumferential surface on the opposite side from the opening/closing direction of the door, In other words, an engaging protrusion with a channel-shaped cross section is provided protruding from the inner circumferential surface of each circumferential area on the inner circumferential surface for an outward-swinging door and on the outer side for an inward-swinging door. The members are attached to each other to achieve airtightness and soundproofing between the door frame and the frame that contacts it, but compared to sliding doors, etc., which are protected from the outside by rain shutters, etc. Therefore, in the case of doors that are directly exposed to the outside at all times, there is the disadvantage that a simple protective measure such as interposing a single airtight member cannot achieve sufficient airtightness and soundproofing. There is an urgent need for early improvement in this regard, especially in areas such as airports, railway lines, and houses near major motorways where high noise levels and strong external noise are noticeable.
It is hoped that a structure will emerge that can effectively provide sufficient airtightness and soundproofing by simply making additional repairs to the existing door, without having to upgrade to an expensive soundproofing sash door.

In view of these conventional circumstances, this idea was developed to create an airtight and soundproof structure for doors, etc., which can be applied to existing outward-opening doors using extruded aluminum to effectively achieve airtightness and soundproofing. This is a new proposal.

The device according to this proposal has a frame body and a door frame body, and the corresponding vertical frame of the door frame body is hinged to one vertical frame of the frame body so as to be able to open and close outward. In addition, the first airtight member is engaged with the engagement protrusion protruding from the inner circumferential end surface of the frame body, and the door frame body is brought into contact with the first airtight member to obtain airtightness and soundproofing effects. In the configuration of the existing outward-opening aluminum sash door, a channel-shaped engagement member is provided at the outer circumferential end surface of each frame closer to the outside than the first airtight member in the door frame body, and in contact with the inside of the outer overhanging piece of each frame. At the same time, an attachment having a mating portion is attached, and a second air-tight member is engaged with the channel-shaped engagement portion to be brought into contact with the inner circumferential end surface of the frame body toward the outside, and an independent air-tight member is attached between these two air-tight members. This is an airtight and soundproof structure for doors, etc., which is characterized by being able to configure a space.

Hereinafter, one embodiment of the airtight soundproof structure according to this invention will be described in detail with reference to FIGS. 1 and 2.

FIGS. 1 and 2 are a vertical sectional view and a cross sectional view showing the general structure of an existing outward-opening aluminum sash door to which this embodiment is applied.

In each of these figures, an existing outward-opening aluminum sash door used in a general house, for example, has an existing frame A consisting of an upper frame 1, a lower frame 2, and left and right vertical frames 3a, 3b, and an upper frame 5. , a lower stile 15 and an existing door frame body B consisting of left and right vertical frames 4a, 4b, and a hinge C is attached to the right vertical frame 3b of the existing frame body A.
The right vertical stile 4b of the existing door frame B is hinged so that it can be opened and closed outward, and the inner peripheral end face of each frame part of the existing frame A has a channel-shaped cross section. In this case, the upper frame 1 has an engaging protrusion 6, the lower frame 2 has an engaging protrusion 7, and the left and right vertical frames 3a, 3b have engaging protrusions 8a, 8b, respectively. The first airtight member 9 is engaged with each engagement protrusion in series or series, and when the door is closed, this first airtight member 9 is attached to each of the frames 5, 15 and 4a, 4b. Pressure is applied to the contact surface of the peripheral edge so that an airtight effect can be obtained.

In the case of this embodiment, in the configuration of the existing outward-opening aluminum sash door described above, the outer periphery of each frame 5, 15 and 4a, 4b on the outside of the first airtight member 9 in the door frame B is At the end face 14,
Attachments 13 having channel-shaped engaging portions 12 are attached to each of the outer overhanging pieces 11 with, for example, screws or adhesive so as to be in contact with the inside thereof, and a For example, a second fin with fins made of vinyl chloride resin, sponge, etc.
When the second airtight member 10 is engaged and the door frame B is closed in the same manner as described above, this second airtight member 10 is attached to the outer side of the frame A, that is, each frame 1, 2, 3a, 3b. The surrounding frame A and the door frame B are made so that they can be brought into contact with the inner circumferential end surface, and an independent space D having a sufficient volume is formed between both the airtight members 9 and 10.
This prevents air gaps from appearing between the two.

Therefore, in this embodiment having the above configuration, when the existing outward-opening door is closed, the first airtight member 9 first performs airtightness and soundproof sealing as set in advance, and this first 1 airtight member 9
The second airtight member 10 provides airtightness and soundproof sealing, which is the purpose of this invention, at a position closer to the outside via the independent space D having a sufficient volume than the position shown in FIG.

In other words, in this case, the noise that attempts to enter from the outside of the existing aluminum sash door is first blocked by the airtight and soundproof sealing in the first stage by the second airtight member 10, and then the noise that tries to enter from the outside of the existing aluminum sash door is blocked by the airtight and soundproof sealing in the first stage, and then it passes through this first stage. When this happens, the intruding noise is once again sufficiently reduced in the independent space D by its buffering and attenuating effects, and then the second air-tight member 9 is again
The airtight and soundproof sealing at this stage completely prevents noise from entering the inside of the door.

Furthermore, in this embodiment configuration, each frame 5, 15
In order to mount the attachment 13 on the outer peripheral end surface 14 of 4a, 4b and in contact with the inside of each outer overhang piece 11, the mounting position of the attachment 13 is specified in an orderly manner with respect to each stile and mutually connected. In addition to preventing misalignment, each outer overhanging piece 11 can be effectively reinforced from the inside, and the second airtight member 10 with fins is engaged with the channel-like engagement portion 12 of the attachment 13. Therefore, there is no risk that the second airtight member 10 will be exposed to the outside and spoil the appearance, and the second airtight member 10 can be easily replaced.

As detailed above, according to this invention, the first airtight member made of a relatively soft material is engaged with the engagement protrusion protruding from the inner peripheral surface of the frame body,
In an existing outward-opening aluminum sash door in which the door frame is brought into contact with this first airtight member,
An attachment having a channel-shaped engagement portion is installed on the outer circumferential end surface of each frame closer to the outside than the first airtight member in the door frame body and in contact with the inside of each frame outer overhanging piece, and the channel-shaped engagement portion is attached. In addition, a second airtight member that is brought into contact with the inner circumferential end face of the outer side of the frame is attached, and an independent space is formed between these two airtight members, so that the second airtight member is able to Soundproofing and airtightness, buffering and damping effects in the independent space, and second airtightness due to the existing first airtightness.
By providing soundproofing and airtightness at each stage, even high-level and powerful external noise can be appropriately and effectively blocked from entering the door, and the attachment can be easily positioned. In addition to being able to reinforce each stile outside overhang, the second airtight member is also extremely easy to replace.Furthermore, it can be easily applied to existing aluminum sash doors. It has practical benefits such as soundproofing of buildings near noisy airports, railway lines, and major motorways by simple and inexpensive additional repairs, without having to retrofit expensive soundproof sash doors, etc. It has various effects.
