Description

  The present invention relates to a smoke-proof wall and a panel for the smoke-proof wall used therein.

  In general, a sheet glass is used for a smoke-proof hanging wall provided on a ceiling of a building such as an office building or a shopping mall so as not to obstruct the field of view. However, the smoke-proof hanging wall using plate glass may cause a serious accident because the glass may be damaged and dropped due to an earthquake, or the glass may be dropped and greatly damaged and scattered. Therefore, attempts have been made to increase the earthquake resistance of the plate glass mounting structure as an earthquake countermeasure, but the plate glass cannot be completely prevented from falling. In addition, an aluminum panel is also used in place of the plate glass. However, since the aluminum panel is opaque, there is a problem that the visual field is obstructed and the appearance is poor compared to the plate glass.

The smoke proof dripping wall panel of the invention according to claim 7 is a resin for forming the resin coating layer using the glass composition constituting the glass fiber fabric as E glass in the smoke proof dripping wall panel having the above-described configuration. Is a vinyl ester resin.

The smoke-proof hanging wall of the invention according to claim 8 is formed by arranging the smoke-proof hanging wall panels having the above-described configuration.

Since the panel for smoke-proof hanging walls of the invention according to claims 1 to 6 of the present application has a glass fiber sheet attached to the frame to form a panel, it can be handled in the same manner as plate glass, and smoke-proof dripping using plate glass is used. The smoke-proof hanging wall can be formed using the same mounting structure as that of the wall, and the workability is further improved because it is lighter than the plate glass. The glass fiber sheet used in this panel comprises a resin coating layer formed by impregnating and curing a resin in 20 to 70% by weight of a glass fiber fabric, and a resin per unit area of the glass fiber sheet. Since the coating layer has a mass of 10 to 500 g / m ² , the glass fiber fabric is reliably impregnated with the resin, and the resin layer is formed on the surface layer. There is almost no appearance of whitening due to poor impregnation of the resin. Moreover, the difference in refractive index between the glass composition constituting the glass fiber in the glass fiber fabric and the curable resin is ± 0.02 or less, the total light transmittance of the glass fiber sheet is 80% or more, and the glass fiber sheet because there the haze as 30% or less, almost no visible glass fiber fabric, sheets Ri is Do transparent, that have and with excellent optical transparency. For this reason, the smoke-proof hanging wall formed using this smoke-proof hanging wall panel can give an excellent aesthetic appearance without blocking the visual field. Furthermore, since the glass fiber sheet uses a non-combustible glass fiber fabric, the non-combustibility required for a building can be imparted. In addition, when used as a smoke-proof hanging wall, even if it falls during an earthquake or the like, it is safe because it does not break like a glass plate and scatters around. Furthermore, since the shape of the smoke proof dripping wall panel of the present invention is given by the frame body, it is possible to easily provide a hole for passing a pipe, and to form a curved panel. It can respond to various requests.

By the way, glass fiber sheets formed by impregnating and curing glass fiber fabrics are not stretchable, so wrinkles tend to occur when attached to a frame, and when wrinkles occur, the appearance deteriorates and the transparency also decreases. To do. Therefore, in the invention according to claim 1, the frame body is provided with opposed side portions forming long sides and opposed side portions forming short sides, and long sides in a free state before the glass fiber sheet is attached. The side portion on the side has a shape curved outward, the side portion on the short side has a linear shape, and the side portion on the long side is elastically deformed in a substantially linear shape The glass fiber sheet is fixed and the tension by the elastic restoring force of the side portion is applied to the glass fiber sheet, whereby the glass fiber sheet can be kept in a constantly stretched state and has an excellent appearance. Can be given.

Furthermore, in the invention according to claim 2, since the opposing side portions on the short side of the frame body are curved inward instead of being linear, the curved side portion on the long side is inward. When pressurizing and deforming linearly, even if the side portion on the short side is deformed outward, it is not curved outward and a panel having a good appearance can be formed.

In the invention which concerns on Claim 3, the frame is provided with the opposing side part which forms a long side, and the opposing side part which forms a short side, The said side part of a long side is in the said side part of a short side On the other hand, in a form that is movably connected in the longitudinal direction of the side member on the short side, and that the interval between the opposing side portions on the long side can be expanded between the opposing side portions on the long side. Since it is configured to include the interval adjusting means to be coupled, after attaching the glass fiber sheet to the frame body, the interval between the opposing side portions is widened by the interval adjusting means, thereby applying tension to the glass fiber sheet and wrinkling. Can be eliminated.

In the invention according to claim 4, the gap adjusting means, between the opposing side portions of the long sides of the frame body, and a strut member arranged to support the該辺part, at least of the opposite side portions It is configured to have a screw provided on one side and capable of adjusting the position of the column member in the longitudinal direction with respect to the side portion of the column member, and the interval adjusting means of this configuration includes a column member having a simple structure Since only a screw is used, it can be manufactured at a low cost, and by simply rotating the screw, it is possible to widen the interval between the opposing side portions, and the adjustment work can be easily performed.

In the invention which concerns on Claim 5, the said support | pillar member is arrange | positioned at the at least both ends vicinity of the edge | side part which the said frame opposes. When a glass fiber sheet is attached to the frame, wrinkles are likely to occur near the corners of the frame, so by placing strut members near both ends of the opposing side portions, wrinkles that tend to occur near the corners can be efficiently performed. Can be prevented.
In the invention according to claim 6, since the difference in the Abbe number between the glass composition and the resin coating layer is 30 or less, the scattering in the visible light region is reduced at the interface between the glass fiber fabric and the coating resin layer, and coloring is performed. Ki de be suppressed can be formed excellent smoke hanging wall in one layer aesthetics.

Invention, because it is smoke hanging wall which is formed by arranging a smoke hanging wall panels of the above-described configuration, without interrupting the view, while providing excellent aesthetics, function as a smoke hanging wall according to claim 8 Even if it falls in the event of an earthquake or the like, it is safe because it does not break like a glass plate and scatters around.

As described above, the panel for smoke-proof hanging wall of the present invention is obtained by attaching a glass fiber sheet having transparency to a frame, and the glass fiber sheet is impregnated with a resin in a glass fiber fabric to form a sheet. Molded.

  A glass fiber fabric is a material which becomes the base fabric of a glass fiber sheet. As glass fiber which is a material of glass fiber fabric, general-purpose non-alkali glass fiber (E glass), acid-resistant alkali-containing glass fiber (C glass), high strength / high elastic modulus glass fiber (S glass, T glass, etc.) ), Alkali-resistant glass fibers (AR glass), etc., but non-alkaline glass fibers having high versatility are preferably used. The refractive index of the glass composition constituting the glass fiber is such that the difference from the refractive index of the resin used for impregnation is ± 0.02 or less. If the refractive index on the resin side can be selected as desired, glass A composition having any refractive index may be used. As the glass composition, for example, those having a refractive index of about 1.4 to 1.7 are preferred, and those having a refractive index of 1.5 to 1.6 are more preferred. When glass fiber made of non-alkali glass is used, the refractive index is about 1.55 to 1.57.

  Examples of the weave structure of the glass fiber woven fabric include plain weave, satin weave, twill weave, oblique weave, and woven weave. Of these, plain weave, oblique weave and woven weave are preferred. Both the gap between adjacent warps and the gap between adjacent wefts in the glass fiber fabric are preferably 0.5 mm or less, and more preferably 0.2 mm or less. This is because when the gap between adjacent warp yarns or the gap between weft yarns in the glass fiber fabric is narrow, the flame is difficult to pass through the glass fiber fabric. The filament constituting the glass fiber fabric preferably has a diameter of 1 to 20 μm, more preferably 3 to 12 μm. Moreover, 5-70 tex is preferable and the count of glass fiber has more preferable 10-35 tex.

  The glass fiber fabric may be woven with one type of glass fiber, or may be woven with two or more types of glass fibers. For example, the warp and the weft may have the same glass fiber composition and may have different glass fiber counts.

  The glass fiber fabric is preferably surface-treated with a silane coupling agent usually used as a glass fiber treating agent for the purpose of improving the durability of the glass fiber sheet. As a result, the glass fiber fabric and the cured resin can be satisfactorily bonded. In addition, since only a small amount of the silane coupling agent adheres to the surface of each glass fiber, it does not substantially affect the light transmission characteristics and air permeability of the glass fiber fabric.

  The fiberglass fabric may be subjected to a fiber opening treatment. The volume and area occupied by warps and wefts formed by glass fibers by spreading the glass fibers that make up the glass fiber fabric or flattening the cross-sectional shape of the glass fibers by opening the fiber. The range can be increased or deformed. By reducing the thickness of the glass fiber fabric by the fiber opening treatment, the total light transmittance can be increased. At the same time, the fiber can be deformed into a shape suitable for resin impregnation by the fiber opening process.

  The resin coating layer is formed by impregnating a resin into a glass fiber fabric and curing it. The resin coating layer enters a gap between the glass fibers of the glass fiber fabric and forms resin layers on the front and back surfaces. Various resins such as a thermoplastic resin and a thermosetting resin can be used as the resin coating layer. Particularly, the resin can be cured by heat curing or by irradiation with light such as ultraviolet rays. It is preferable to use a curable resin such as a photo-curing type. Such a heat or photo-curing type resin has an advantage that it is easy to be impregnated into a glass fiber woven fabric in an uncured state at about room temperature, with a low viscosity.

  As the material of the resin coating layer, a material having a refractive index difference of ± 0.02 or less from the glass composition of the glass fiber fabric is used. Thus, by making the difference in refractive index between the glass fiber woven fabric and the resin coating layer sufficiently small as ± 0.02 or less, the glass fiber woven fabric cannot be visually recognized in the resin coating layer. Therefore, in the glass fiber sheet, the portion formed by the glass fiber fabric and the resin coating layer can be made transparent to sufficiently increase the total light transmittance of the glass fiber sheet. The method for measuring the refractive index of the resin coating layer is in accordance with “Method for measuring refractive index of plastic” in JIS K7142.

  As the curable resin used for forming the resin coating layer, it is preferable to use a vinyl ester resin, an unsaturated polyester resin, an epoxy resin, etc., because it has excellent heat resistance, chemical resistance, mechanical strength, and curing characteristics. More preferred are vinyl ester resins. The curable resin impregnated into the glass fiber fabric may contain additives such as a flame retardant, an ultraviolet absorber, a filler, and an antistatic agent. Examples of the flame retardant include aluminum hydroxide, magnesium hydroxide, trichloroethyl phosphate, triallyl phosphate, ammonium polyphosphate, and phosphate ester. Examples of the ultraviolet absorber include benzotriazole. Examples of the filler include calcium carbonate, silica, and talc. Examples of the antistatic agent include surfactants. These additives may be in the form of particles, and in the case of particles, the particle size is preferably 10 μm or less, more preferably 5 μm or less. This is because when the particle size is small, the total light transmittance is improved and the haze is lowered.

  The ratio of the glass fiber fabric and the resin coating layer in the glass fiber sheet is 20 to 70% by weight for the glass fiber fabric and 80 to 30% by weight for the resin coating layer. When the glass fiber fabric is less than 20% by weight, the amount of resin increases, and the incombustibility of the obtained glass fiber sheet decreases. On the other hand, when the glass fiber woven fabric exceeds 70% by weight, the amount of resin in the surface layer of the obtained glass fiber sheet is decreased, and the pattern of the glass fiber woven fabric may be raised, and whitening due to poor impregnation may occur. It may occur, and transparency is further reduced.

The mass of the glass fiber fabric per unit area of the glass fiber sheet is determined in consideration of the strength, durability and resin impregnation property of the glass fiber sheet. For example, it may be about 10 to 300 g / m ^2. In particular, in order to improve the strength and durability of the glass fiber fabric and the impregnation property of the resin into the glass fiber fabric, the mass of the glass fiber fabric is preferably ²⁰ to 300 g / m ² . By setting the mass of the glass fiber fabric to 20 g / m ² or more, the strength of the glass fiber sheet can be sufficiently increased. In addition, by setting the mass of the glass fiber fabric to 300 g / m ² or less, the ratio of the glass fiber fabric per unit area of the glass fiber sheet is decreased, the gap between the glass fiber fabrics is sufficiently increased, and the resin impregnation is poor. Can be prevented. When the mass of the glass fiber fabric per unit area of the glass fiber sheet is set to 150 g / m ² or more, one thick glass fiber fabric may be used, or a plurality of thin glass fiber fabrics may be used. May be. From the viewpoint of improving the impregnation property, it is preferable to use a plurality of thin glass fiber fabrics.

Mass of the resin coating layer per unit area of the glass fiber sheet, and 10 to 500 g / m ^2. By setting the mass of the resin coating layer to 10 g / m ² or more, it is possible to prevent the pattern of the glass fiber fabric from being raised or the resin from appearing whitened due to poor impregnation. In addition, by setting the resin mass to 500 g / m ² or less, the ratio of the resin, which is a relatively flammable part of the glass fiber sheet, is kept low, and the glass fiber sheet has excellent flame retardancy Can do.

It is preferable to select the material of the resin forming the resin coating layer so that the difference in Abbe number between the glass composition constituting the glass fiber in the glass fiber fabric and the resin coating layer is 30 or less. By suppressing the difference in Abbe number to 30 or less, scattering in the visible light region can be reduced at the interface between the glass fiber fabric and the resin coating layer, and coloring at the interface can be suppressed. The Abbe number is a numerical value for evaluating the chromatic aberration of the transparent body, and is represented by the Abbe number V = (n _D −1) / (n _F −n _C ). Here, n _D is a refractive index for light having a wavelength of 589.2 nm, n _F is a refractive index for light having a wavelength of 486.1 nm, and n _C is a refraction for light having a wavelength of 656.3 nm. Rate. In addition, although there is no restriction | limiting in particular in the Abbe number of a glass composition, For example, it is preferable that it is the range of 35-75, and it is still more preferable that it is the range of 50-70.

The glass fiber sheet has a total light transmittance of 80% or more and a haze of 30% or less . Among them, the total light transmittance is 85% or more and the haze is 20% or less. preferably not more, it is preferable to select a resin material so that these numerical ranges. Here, the total light transmittance and haze are numerical values indicating how transparent the sheet is. The greater the total light transmittance and the smaller the haze, the higher the transparency. In addition, the measuring method of the total light transmittance of a glass fiber sheet follows JIS K 7105 "Optical characteristic test method of plastic", "5.5 Light transmittance and total light reflectance". The haze measurement method follows JIS K 7105 “Testing method for optical properties of plastic” and “6.4 haze”.

  The glass fiber sheet having the above-described configuration can be manufactured using a conventional method for manufacturing a fiber-reinforced resin sheet. For example, a glass fiber fabric is continuously run, and a first carrier film coated with an uncured resin is pressed against one surface of the glass fiber fabric while continuously running, and the other side of the glass fiber fabric is pressed. The second carrier film is pressed against the surface while continuously running, and the glass fiber fabric and uncured resin are sandwiched between the first and second carrier films, and the resin is cured. It can be manufactured using a continuous forming method for forming into a glass fiber sheet. It can also be manufactured by a batch method using a mold.

  The frame body used for the panel for smoke proof dripping wall of this invention is for giving the desired shape suitable for forming a smoke proof dripping wall to this panel while supporting a glass fiber sheet. For the frame, a material that has nonflammability and can secure the required strength may be used. Specifically, metal materials such as stainless steel and aluminum, and nonflammable inorganic fibers such as glass fibers are used. A fiber-reinforced resin molded article or the like can be used.

  Hereinafter, preferred embodiments of the panel for smoke-proof hanging wall of the present invention will be described. FIG. 1 (a) is a schematic perspective view of a panel for smoke proof hanging walls (hereinafter abbreviated as a panel) according to an embodiment of the present invention, FIG. 1 (b) is a schematic plan view of the panel, and FIG. 1 (c). Is a schematic sectional view of the panel, FIG. 2 is a schematic plan view showing the frame body in a free state before attaching the glass fiber sheet, and FIG. 3A is a state when attaching the glass fiber sheet to the frame body. FIG. 3B is a schematic plan view of a panel formed by attaching a glass fiber sheet to the frame. The panel denoted as a whole by reference numeral 1 has a rectangular plane, is arranged on the frame 2, the glass fiber sheet 3 disposed on one surface thereof, and fixed to the frame 2, and fixed to the frame 2. The outer frame 4 attached to the outer side of the frame body 2 is provided so as to protect the glass fiber sheet 3 in the portion. This glass fiber sheet 3 has the above-described configuration, and has excellent transparency, incombustibility, and the like. A metal material such as aluminum is used for the outer frame 4.

  The frame 2 is formed of a hollow rectangular pipe made of a metal material having high strength and rigidity such as stainless steel. In addition, you may use not only a hollow square pipe but a solid square-shaped material. In a free state before the glass fiber sheet 3 is attached, the frame body 2 has a generally rectangular shape as shown in FIG. 2, and opposed side portions 2a and 2a that form long sides. And opposing side portions 2b and 2b formed by short sides. The opposing side portions 2a, 2a on the long side are curved outward as shown exaggeratedly in FIG. This bending amount will be described later.

  When assembling the panel 1, as shown in FIG. 3 (a), the opposed side portions 2a, 2a on the long side of the frame 2 are pressed inward by a jig (not shown) such as a press. In this state, the glass fiber sheet 3 is disposed on one surface of the frame body 2, and the glass fiber sheet is attached to the side portions 2a and 2a and the side portions 2b and 2b. The attachment of the glass fiber sheet 3 to the frame 2 is optional, such as fixing with an adhesive (including an adhesive), fixing with a screw, etc., but using an adhesive (for example, using a double-sided tape) Since it becomes easy, it is preferable. The glass fiber sheet 3 may have a structure in which the glass fiber sheet 3 is positioned and fixed only on the upper surfaces of the side portions 2a and 2a and the side portions 2b and 2b of the frame body 2, and as shown in FIG. And it may be arranged and fixed so as to go around the back surface. After the glass fiber sheet 3 is attached to the frame 2, the jig that pressurizes the side portions 2a and 2a inside is removed, and the outer frame 4 (see FIG. 1) is attached. Thus, the rectangular panel 1 shown in FIG. 1 is formed.

  Here, as shown in FIG. 3 (b), after fixing the glass fiber sheet 3 to the frame body 2, after removing the jig that pressed the side portions 2a, 2a, the side portions 2a, 2a are themselves The elastic restoring force tries to return to the original shape (the shape curved outward as shown in FIG. 2), but the side portions 2a and 2a are restrained by the glass fiber sheet 3 having a small elongation, It is held in a straight line. On the contrary, the glass fiber sheet 3 is given a perpendicular tension to the long side of the frame 1 as indicated by the arrow T by the outward elastic restoring force generated in the side portions 2a and 2a. As a result, the glass fiber sheet 3 is always held in a stretched state, and a wrinkle that tends to occur when the glass fiber sheet 3 having a small elongation is stuck to the frame 2 does not occur, and a panel having a good appearance is obtained. It is done. The amount of bending to be applied to the side portions 2a and 2a of the frame 2 is such that the elastic restoring force of the side portions 2a and 2a is fixed after the side portions 2a and 2a are elastically deformed linearly and the glass fiber sheet 3 is fixed. What is necessary is just to determine so that the tension | tensile_strength which can suppress generation | occurrence | production of wrinkles can be added to the glass fiber sheet 3, for example, when the length of the side part 2a is 1500 mm, the maximum amount of bending (dimension d of FIG. 2) May be about 8 mm.

  In the frame 2 shown in FIG. 2, the side portions 2a and 2a on the long side are curved outward, and the side portions 2b and 2b on the short side are linear. In this structure, when the curved side portions 2a and 2a are pressed inward and deformed linearly, the short side portions 2b and 2b may be slightly curved outward. Since this curvature is slight, it is not a problem in many cases. However, when the curvature is not negligible, the side portions 2b and 2b on the short side are not curved outward when the glass fiber sheet 3 is attached. What is necessary is just to regulate by pressing an appropriate jig. Alternatively, a frame 2A having the shape shown in FIG. 4 may be used. In this frame 2A, the side portions 2a and 2a on the long side are curved outward, and the side portions 2b and 2b on the short side are curved inward. In this way, when the side portions 2b and 2b on the short side are curved inward in advance, when the side portions 2a and 2a curved outward are pressed inward and deformed into a linear shape, The side portions 2b and 2b are not curved outward, and a panel having a good appearance can be formed.

  5A, 5B, and 5C are a schematic plan view, a schematic back view, and a schematic cross-sectional view of a panel according to another embodiment of the present invention. FIG. 6 is a schematic plan view of a frame used for the panel. 7A is a schematic cross-sectional view taken along the line AA in FIG. 6, FIG. 7B is a schematic cross-sectional view taken along the line BB in FIG. 6, and FIG. 8 is a glass fiber sheet attached to the frame. It is a schematic sectional drawing explaining the operation | movement which removes the wrinkle of a glass fiber sheet. The panel 11 according to this embodiment also includes a frame 12, a glass fiber sheet 13 attached to the frame 12, and a protective outer frame 14. The glass fiber sheet 13 has the above-described configuration, and has excellent transparency. And nonflammability. A metal material such as aluminum is used for the outer frame 14.

  The frame body 12 is made of a metal material such as an aluminum material. The frame 12 has a generally rectangular planar shape, and opposing side portions 12a and 12a that form long sides and opposing side portions 12b and 12b that form short sides are linear. And it is made as a separate part. The end portion of the side portion 12a is disposed at a position where it abuts against the end surface of the side portion 12b. As can be clearly understood from FIG. 7A, the end portion of the side portion 12b and the end portion of the side portion 12a have the side portion 12b. In the free state, a connecting member 15 having a C-shaped cross section having a diameter larger than that of the hole is inserted to connect the side portion 12a and the side portion 12b. With this connection structure, the side portion 12a is fixed to the side portion 12b, but is movable when a large force in the longitudinal direction of the side portion 12b is applied to the side portion 12a. For this reason, the side portions 12a and 12a facing each other on the long side of the frame body 12 can increase or decrease the distance between them. On the inner side of the opposed side portions 12a and 12a on the long side of the frame body 12, a space adjusting means 17 is provided for connecting the side portions 12a and 12a in a form in which the space between them can be enlarged.

  The interval adjusting means 17 includes a plurality of support members 18 arranged so as to support the side portions 12a and 12a between the side portions 12a and 12a facing each other. This strut member 18 is provided with screws 18a and 18b whose screw directions are opposite to each other at both ends as an integral structure, and the screw holes 18a and 18b are formed in opposing side portions 12a and 12a. The screws 19a and 19b are respectively engaged with screws. With this configuration, the interval between the opposing side portions 12a and 12a can be increased by rotating the column member 18 in one direction, and the interval can be reduced by rotating in the opposite direction. Grooves are formed in the tip surfaces of one or both of the screws 18a and 18b so that they can be rotated by a screwdriver. The strut member 18 is disposed in the vicinity of both ends of the opposing side portions 12a and 12a (for example, a region having a distance of 50 mm or less from the side portion 12b connected to the end portion of the side portion 12a) and suitable for the intermediate region. It is arranged with a wide space. Further, the support member 18 is attached in the thickness direction of the frame body 12 so as to enter the thickness of the frame body 12 and not to come out of the frame body. The outer frame 14 is perforated so that a screwdriver can be passed through the outer frame 14 at a position facing the screw holes 19a, 19b of the frame 12 when the outer frame 14 is attached to the frame 12.

Next, a method for manufacturing the panel 11 using the frame body 12 having this configuration will be described. First, the frame body 12 is assembled as shown in FIG. At this time, the interval between the opposed side portions 12 a and 12 a is set so that it can be expanded by the rotation of the support member 18. Next, the glass fiber sheet 13 is disposed on one side of the frame body 12, and the peripheral portion thereof is fixed to the side portions 12a and 12a and the side portions 12b and 12b with an adhesive or the like. At this time, even if the glass fiber sheet 13 is stretched and fixed to the frame body 12, the glass fiber sheet 13 hardly stretches, and thus wrinkles are likely to occur. In particular, wrinkles may occur near the corners of the frame body 12. Many. Then, after sticking the glass fiber sheet 13, while observing the wrinkles occurring in the glass fiber sheet 13, the strut member 18 of the wrinkled portion is rotated while grasping the intermediate region, or the screw 18 a. Or it rotates with a driver using the groove | channel formed in the end surface of 18b, and as shown in FIG. 8, the space | interval of the opposing side parts 12a and 12a is expanded. Thereby, the tension | tensile_strength of the direction shown by the arrow is added to the glass fiber sheet 13, and a wrinkle is eliminated. Thereafter, the outer frame 14 is attached. Thus, the rectangular panel 11 shown in FIG. 5 is formed.
