Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a glass sheet that suppresses glare by an inexpensive and simple method.
[0002]
[Prior art]
The cutting of the plate glass is performed by making a cut with a glass cutting tool such as a diamond cutter on the surface at a predetermined cutting location, and folding the cut by applying an external force. The edge that is the cut surface of the plate glass cut in this way is not smooth when viewed microscopically, and has a concavo-convex shape composed of an infinite number of surfaces facing various directions. When applied to partitions, door plates, furniture doors, etc. without applying any treatment to the edge of such a sheet glass, light is diffusely reflected at the edge having innumerable fine irregularities, so that it is viewed from the surface side of the sheet glass. Will cause glare. Therefore, it has been conventionally practiced to reduce the fine unevenness as much as possible by performing a smoothing process by rough machining called roughing on the edge of the plate glass as much as possible to suppress glare. In particular, a thick plate glass is used in the partition that applies a plate glass having a height from the floor surface to the ceiling over the entire surface. Roughing is required.
[0003]
[Problems to be solved by the invention]
However, such a smoothing process cannot be performed unless a dedicated device is used in a factory, and tends to be expensive. In addition, for example, when the size of the plate glass does not match at the construction site of the plate glass used for partitioning etc., the installer often scratches and folds the surface of the plate glass at the site to adjust the size of the plate glass. However, since it is not possible to smooth the edge at the construction site, either work with the minute unevenness left in the mouth, or carry the plate glass again to the factory and perform the smoothing treatment, and then again at the construction site. I have to go back to In other words, glare can not be suppressed if the cut glass is applied as it is to match the size at the site, and if the smoothing process is performed again at the factory, glare will be suppressed, but extra cost, time and labor will be required. .
[0004]
SUMMARY OF THE INVENTION In order to solve the above-described problems, an object of the present invention is to make it possible to easily carry out an anti-glare process at a construction site at a very low cost.
[0005]
[Means for Solving the Problems]
That is, the plate glass for use in the present invention is obtained by sticking a resin film to a small edge that is a cut end surface of a plate-like glass body that has not been subjected to a smoothing treatment.
[0006]
If this is the case, a large number of minute irregularities formed on the small edge just scratched and broken on the glass body are absorbed by the resin film attached to the small edge to bring it closer to a smooth state. Therefore, glare can be suppressed without performing a smoothing process for the mouthpiece at the factory. In addition, since only a very simple process of sticking the resin film to the fore edge is required, the cost for it can be effectively reduced.
[0007]
Moreover, the plate glass for use in the present invention may be one in which a liquid or paste-like resin is applied to a small edge that is a cut end surface of the plate-like glass body that has not been smoothed. That is, in this case as well, it is possible to easily prevent glare of the plate glass because it can be absorbed by the resin coated with innumerable minute irregularities in the fore edge by an inexpensive and simple treatment, so that it can be brought close to a smooth state. From the above, for example, even when the installer cuts the glass body to a predetermined size for size adjustment at the construction site of sheet glass, glare can be prevented by applying a resin film or applying resin to the cut edge As a result, it is possible to eliminate the need to carry the plate glass into the factory again and perform a smoothing process using dedicated equipment.
[0008]
Even in the case of a plate glass in which the cut end portion including the edge of the glass body is inserted into a part of a holding member that holds the glass body, glare due to a rough edge occurs, so a resin film may be attached to the edge. It is effective to apply a liquid or paste resin. In this case, particularly when the insertion depth dimension of the glass main body to the holding member is set to be equal to or smaller than the thickness dimension of the glass main body, glare due to a rough edge tends to occur. In order to prevent glare, it is effective to apply a resin film to the forehead or to apply a liquid or paste-like resin.
[0009]
The present invention as a suitable application example of the plate glass as described above is a partition formed by making the height dimension of the glass body substantially correspond to the height from the floor surface to the ceiling and holding the four sides of the glass body by a frame. It is applied to a wall, and part or all of the frame is configured from the holding member. That is, the partition according to the present invention includes a plate glass mainly composed of an adjacent plate-shaped glass body, and a frame body that holds the glass body, and the height of the glass body is determined from the floor surface. Applying a resin film or applying a liquid or paste-like resin to a small edge which is a cut end surface of the glass body that is not smoothed so as to substantially correspond to the height to the ceiling. Part or the whole is constituted by a holding member that holds a cutting end including a small edge of the glass body, and the holding member is adjacent to each other in a posture of sandwiching from both surface sides of adjacent glass bodies. At the same time to hold the two sheets of plate glass transparent or translucent joint member der composed of is, the joint member includes a first joint element arranged on one surface side of the glass body, other And the second joint element disposed on the surface side of the glass plate, and the second joint element is engaged with the first joint element, so that the glass sheet is smaller than the thickness dimension of the glass body from both surface sides. It is characterized in that two adjacent glass plates are held at the same time in a posture sandwiched in depth . In such a partition, the upper end and lower end of the plate glass are far away from the human eye, so there is less glare from the edge of the upper and lower ends of the plate glass to the person in front of the partition wall, but compared to that People often feel glare from the edge of the side edge of the glass sheet. Therefore, in order to effectively suppress such glare, it is possible to apply the resin film or apply a liquid or paste-like resin to the edge that forms at least the side end of the glass body. preferable.
[0010]
In this way, in the case of a partition in which a plate glass is held by a frame, a thick plate glass is often used, so that the area of the fore edge becomes large, and if a plate glass that is simply cut is used, diffuse reflection at the fore edge It is easy to cause glare by. Therefore, the partition which suppressed glare can be easily comprised by sticking a resin film to the edge of a glass main body as mentioned above, or apply | coating liquid or paste-like resin. Note that glare tends to occur when the insertion depth of the glass body into the frame is less than or equal to the thickness of the glass body. In such a case, a resin film is applied to the small edge or a resin is applied. Is extremely useful.

And between opening part 33B2 which adjoins, the opening part 33B3 which makes a planar view U-shape and opens outside is formed. Then, the side end 13 of the glass sheet 1 is inserted from the side into the opening 33B3, and the glass beads 35 are inserted into the gap between the opening 33B3 and the front and rear surfaces 2a of the glass body 2. The plate glass 1 is held by the side frame member 33B so as to suppress the movement of the plate glass 1 in the front-rear direction. A resin cover 33B4 is attached to the opening 33B3 of the side frame member 33B that does not hold the plate glass 1 to maintain the appearance. Here, as shown in an enlarged view in FIG. 4, the insertion depth L1 of the side frame member 33B at the side end 13 of the glass sheet 1 into the opening 33B3 is larger than the thickness t (about 10 mm) of the glass body 2. For example, it is about 7 mm so as to be small. The side end 13 of the glass sheet 1 is also inserted into the opening 33A3 of the side frame member 33A by about 7 mm, but the enlarged illustration is omitted.
[0017]
Moreover, as shown in FIG.1, FIG3 and FIG.5, the joint material 34 is arrange | positioned between the side edge 13 parts of the adjacent plate glass 1, and all are the height dimensions from the floor surface F to the ceiling R. And the first joint element 341 disposed on the one surface 2a side of the glass body 2 and the second joint element 342 disposed on the other surface 2a side. The first joint element 341 has a partial arc shape, and a pair of opposing walls extending from the inner surface of the base wall 341a in the thickness direction of the glass sheet 1 with both end portions being in contact with the surface 2a of the adjacent glass body 2 respectively. The wall 341b is integrally formed by extrusion molding of transparent or translucent ABS resin or the like. A claw portion 341c is formed at the tip of each facing wall 341b so as to project to the opposite side. The second joint element 342 has a shape similar to that of the base wall 341a of the first joint element 341, and a base wall 342a that makes both ends abut against the surface 2a on the opposite side of the adjacent glass body 2, respectively. A single protruding wall 342b extending in the thickness direction of the glass sheet 1 from a substantially central portion on the inner surface of the base wall 342a is integrally formed by extrusion molding of a transparent or translucent ABS resin or the like. The tip of the protruding wall 342 is formed in an arrow shape. Then, the front end portion of the protruding wall 342b of the second joint element 342 is inserted between the opposing walls 341b of the first joint element 341 and is engaged with the claw portions 341c, respectively, so that the plate glass 1 is placed on both surfaces 2a side.

The side edge part 13 of the plate glass 1 is inserted with the depth dimension L2 of about 5 mm.
[0018]
Here, the “surface roughness measuring machine (model number SE3500) of the roughness of the surface of the small mouth 21 to which the film 22 of the glass body 2 is not attached and the roughness of the surface of the film 22 opposite to the attachment side after the film 22 is attached. ) "Shows the measurement results. That is, the surface roughness of the forehead 21 of the glass body 2 to which the film 22 is not attached, that is, the maximum width of the unevenness in the direction orthogonal to the surface of the forehead 21 was about 0.405 mm, The surface roughness of the film 22 affixed to 21 was about 0.126 mm. Moreover, the uneven | corrugated cycle at the time of sticking the film 22 on the small edge 21 was significantly small with respect to the uneven | corrugated cycle in the small edge 21 of the glass main body 2. In addition, when the surface roughness in the plate glass which rough-processed the edge was measured for the comparison, the measured value near zero was obtained infinitely.
[0019]
From the above, in the glass plate 1 inserted at the depths L1 and L2 smaller than the thickness dimension t with respect to the openings 33A3 and 33B3 of the side frame member 33 of the frame 3 and the opening 343 of the joint member 34, When the small edge 21 side is viewed from the surface 2a of the glass body 2, glare caused by irregular reflection of light can be effectively suppressed even though the small edge 21 is not roughened. It is inferred that this is due to the interaction between the surface roughness being reduced and the unevenness cycle being reduced by secondarily covering the edge 21 of the glass body 2 with the resin film 22. .
[0020]
For this reason, the small edge 21 of the glass body 2 cut by a normal method of applying an external force after scratching the surface 2a with a diamond cutter is subjected to roughing processing in a factory that requires a lot of labor and cost. Even if it is not, glare of the side end portion 13 of the plate glass 1 in the movable partition wall A can be prevented by an extremely simple method of sticking the film 22 to the fore edge 21. Therefore, for example, in the construction site of the movable partition wall A, if the size of the plate glass 1 does not match the frame 3, even if the plate glass 1 is cut and the size is adjusted at the site, the film 22 is applied to the cut edge 21. Since it only has to be pasted, the labor and cost of construction can be reduced extremely effectively.
[0021]
In addition, the glare prevention measure of the plate glass by this invention is not restricted to the said embodiment of sticking the resin film 22 to the glass main body 2. FIG. That is, as shown in FIG. 6, the same effect as that of the above embodiment can be obtained by applying silicon rubber 23 to the small edge 21 of the glass body 2 that is simply cut. The silicone rubber 23 is preferably transparent or semi-transparent. Here, for example, a room temperature curable liquid silicone rubber used for bonding, sealing, coating, etc. (for example, Shin-Etsu Silicone RTV, trade name “Shin-Etsu Silicone RTV”). “Rubber”, model number KE445) is applied to the small mouth 21 with a brush or the like. Thus, as a result of measuring the surface where the silicon rubber 23 was applied to the fore edge 21 with the surface roughness measuring device as in the above embodiment, the measured value was about 0.340 mm. Moreover, the uneven | corrugated cycle was also small like the said embodiment. From this, it is possible to suppress the glare of the plate glass 1 by applying silicon rubber 23 to the fore edge 21 of the glass body 2 instead of applying the resin film 22. In addition to the above-mentioned silicon rubber, a general liquid or paste-like resin that is cured after coating used as a coating agent, sealing agent, adhesive, etc. may be applied to the mouth. The same effect can be obtained.
[0022]
Further, the present invention can be applied to various furniture and building materials in which plate glass is used, such as partitions such as partition panels, glass windows, and glass cases, in addition to the partition walls as in the above embodiment. In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
[0023]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0024]
That is, according to the present invention, the surface of the fore edge can be obtained by applying a resin film to the fore edge that is a cut end face that has not been smoothed in the plate-like glass body, or by applying a liquid or paste-like resin. The roughness is reduced and the uneven cycle is reduced, so that the glare of the plate glass due to the rough edge can be effectively suppressed. Therefore, it is possible to prevent glare easily and inexpensively at the construction site without performing the smoothing processing of the glass edge in the factory, and it is possible to extremely effectively reduce the construction work time, labor and cost. .
[0025]
Moreover, if it is a partition which stuck the resin film to the edge as mentioned above, or was hold | maintained to the frame with the plate glass which apply | coated liquid or paste-like resin, the suitable which suppressed the glare by the irregular reflection of the light in a edge is effectively suppressed. Therefore, it is possible to configure the partition with a low cost. In particular, in the case of a movable partition wall that uses full-surface glass with a size that roughly corresponds to the height from the floor to the ceiling, the resin is applied to the edge at the side edge of the plate glass that corresponds to the height of human eyes. By applying a film or the like, glare prevention can be made more effective.
