Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a sliding window with excellent sound and heat insulation functions.

(Prior art) In order to improve the soundproofing effect of a sliding window equipped with a pair of inner and outer window shoji that are fitted into the window frame and can be opened and closed from left and right, grooves in the shoji frame into which single-pane glass is inserted have traditionally been used. Then, the adapter was fitted, and a pair of glass plates were fitted into the grooves of the adapter with a spacer interposed therebetween at a distance of about 6 mm.

In addition, a special shoji frame for double-glazed windows was made, and a pair of glass plates were fitted into the shoji frame with a distance of 6 mm to 12 mm to create a soundproof window.

(Problem that the invention aims to solve) However, in conventional soundproof sliding windows, the air layer formed between a pair of glass plates is 6 mm.
or 12 mm, it caused resonance transmission in the low frequency range and did not have sufficient sound insulation performance. Furthermore, when using a shoji stile for double-paned windows, a special shoji stile must be used, which has the disadvantage of increasing construction costs due to lack of versatility.

This invention was devised to solve the above-mentioned problems, and the purpose of this invention is to be able to use the conventional single-pane glass shoji shoji frame, but to be able to move it back and forth, and to improve sound insulation and heat insulation performance. Located in providing excellent soundproofing sliding windows.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a pair of inner and outer window shoji of a sliding window, each of which has two sheets of glass attached to the inner circumferential side of the stile via a holder. At the same time, the sheet glass on the indoor side is removably attached along with a part of the holder from the indoor side, and one of the two laminated glass sheets is attached to the indoor side for the inner window shoji, and for the outer window. The shoji should be gripped with the outdoor side protruding outward, and the average distance between each laminated glass should be 40 mm.
The thickness was set to 100 mm or less, and a sound absorbing material was attached to the periphery of the air layer formed between the laminated glass plates using a perforated board.

(Function) Because the holder that holds the pair of glass plates is attached to the inner circumference of the stile, the stile and sash frame can be used for conventional single-pane glass, providing versatility. Part of the holder can be removed freely, increasing the average distance between glass plates to 40 mm or more.
The air layer formed below 100mm shifts the resonant transmission frequency in the low temperature range to lower frequencies than the lower limit of the audible range, resulting in high soundproofing performance.

(Example) Examples will be described below based on the accompanying drawings.

FIG. 1 shows a front view of the soundproof double sliding window according to the present invention, and 1 in the figure consists of an upper frame 2, a lower frame 3, and left and right side frames 4, 5, and a pair of window shoji 6a, 6 inside.
This window frame 1 is fitted and fixed to the wall of a building.

As shown in FIG. 2, an upper frame guide rail 21 is provided on the upper frame 2 of the window outer frame 1 to project downward, and a lower frame guide rail 31 is provided on the lower frame 3 to project upward. .

On the other hand, the window shoji 6a on the outdoor side A fitted in the window frame 1 has a shoji stile 7 on the outermost periphery, and the shoji stile 7 includes an upper stile 71, a lower stile 72, and left and right side stile 73, 74.
Consists of. An upwardly open groove 71a is formed on the upper edge of the upper stile 71, and the groove 71a is engaged with the upper frame guide rail 21, and the lower edge of the lower stile 72 is connected to the lower frame through the door roller T. It is mounted in a position where it is placed on the guide rail 31.

A glass groove 73 with an open inner side is formed on the inner peripheral side of the shoji frame 7, and a holder 8 for holding a glass plate is fitted into the groove 73 via a beat 9 having a sealing function. The holder 8 has an upper part 8
1. Consists of a lower part 82, left and right side parts 83, 84,
The angle members 10 are connected into a rectangular shape. Each part 81, 82, 83, 84 is a mounting part 81a, 82a, 83a, 84 attached to the groove part 73, respectively.
a, horizontal wall portions 81b and 82 extending to the outdoor side A;
b, 83b, 84b and side wall portions 81b, 82b, 8
3b, 84b to inclined wall portions 81c, 82c, 83
Hanging wall portions 81d, 8 extending through c, 84c
2d, 83d, 84d and hanging wall portions 81d, 82
It consists of holding parts 81e, 82e, 83e, and 84e that are formed continuously from d, 83d, and 84d. The glass plate G ₁ is attached to the holding portions 81e, 82e, 83e, and 84e via the beats 11 and 11 at the rim 12.
It is installed by

Holding pieces 81f, 82f, 83 are provided on the inner periphery of each part 81, 82, 83, 84 on the indoor side of the holder 8.
f, 84f and hook-shaped locking parts 81g, 82g, 83
g, 84g are formed, and locking portions 81g, 82g,
A rectangular holder 13 for holding the glass plate _G2 is detachably attached to 83g and 84g from the indoor side B. The holder 13 is formed in a substantially channel cross-sectional shape with an open outdoor side, and has hook-shaped locking portions 13a on the outer peripheral side that are engaged with the locking portions 81g, 82g, 83g, and 84g, and has a hook-shaped locking portion 13a on the inner peripheral side. A holding portion 13b is provided on the side, and the glass plate G ₂ is attached by a ridge 14 via the beats 11, 11.

With the above configuration, glass plate G ₁
An air layer S having an air layer interval d is formed between the glass plate G2 and the glass plate _G2 .

It is generally known that the air space interval d exhibits the relationship fr≒267/√md, where fr (Hz) is the low-frequency resonant transmission frequency and m (g/cm ² ) is the surface density of the glass.

Therefore, as shown in the above equation, the air layer spacing d affects resonance transmission in the bass range, and as d increases, fr becomes smaller, shifting the resonance transmission frequency fr in the bass range to a low frequency region outside the audible range. The wider the air space interval d, the better. That is, in order to stay out of the audible range, the air space interval d needs to be 40 mm or more.

However, if the air layer spacing d is too wide, problems will occur in terms of the window function, ie, the installation of screen doors and rain shutters, so it is preferable that the air layer spacing d be 100 mm or less.

In addition, since it has an air layer S, it has not only the above-mentioned soundproofing performance but also an excellent heat insulating effect.

In this example, the optimum air layer spacing d was set to 50 mm from the viewpoint of sound insulation performance and construction performance. Further, in this embodiment, each of the glass plates G ₁ and G ₂ is a single plate with a thickness of about 3 to 5 mm, but one of the glass plates may be a soundproof laminated glass with a thickness of about 6 to 8 mm. By using the soundproof laminated glass in this way, it is possible to reduce the drop in the coincidence effect in the high frequency range.

A water-repellent glass wool sound absorbing material 15 is attached to the periphery of the air layer S using a perforated board 16. The sound absorbing material 15 enhances the sound absorption between the glass plates G ₁ and G ₂ and prevents the sound pressure level from increasing due to repeated reflections. Furthermore, by changing the hole diameter, pitch, and thickness of the perforated board 16, the sound absorption of a specific frequency can be increased, and the sound insulation properties can be further improved.

Although the window shoji 6a on the outdoor side A has been described above, the window shoji 6b on the indoor side B has a similar configuration, and the window shoji on the indoor side is designed so that each window shoji 6a, 6b can be opened and closed in the sliding direction. The indoor side glass plate 6b is projected to the indoor side and is detachably held and fitted into the window frame 1.

Although the glass plates G ₁ and G ₂ are parallel in the above embodiment, they may be parallel or non-parallel. That is, the fourth
As shown in the figure, the air layer S' may be formed into a wedge shape by making the upper end of the glass plate _G1 protrude outward by a holder 8', and the air layer spacing d' in such a non-parallel case is:
By setting the average value of the distance d ₁ between the upper end and the distance d ₂ between the lower end and setting the air layer distance d', which is the average distance, to 40 mm or more and 100 mm or less, the same sound insulation performance as in the first embodiment can be obtained.

Also, by protruding the upper end of the glass plate G ₁ on the outdoor side and tilting it at a predetermined angle,
Summer sunlight S is totally reflected when the angle of incidence θ _s on the glass surface of glass plate G ₃ is close to the critical angle, so that almost no light energy reaches the inside of the room, which is advantageous for cooling, and also Light W
is almost incident on the inside of the room, which is advantageous for heating purposes.

(Effects of the invention) Because the glass plates are laminated and attached to the frame of the window shoji using a holder, conventional single-pane glass can be used for the window frame and frame, and the construction cost is low. , the average spacing of laminated glass plates is 40mm
Since it is 100 mm or less, it has excellent soundproofing and heat insulation performance.

Further, since the plate glass on the indoor side is attached so that a part of the holder can be removed from the indoor side, it can be easily and safely removed for cleaning work.

Furthermore, since the sound-absorbing material is attached to the periphery of the air layer formed between the laminated glass plates using a perforated board, the sound-absorbing material increases the sound absorption between the glass plates and prevents an increase in the sound pressure level due to repeated reflections. Ru. Note that by changing the hole diameter, pitch, and thickness of the perforated board, the sound absorption of a specific frequency can be increased, and the sound insulation performance can be further improved.
