Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a reinforced laminated board,
In particular, the present invention relates to a reinforced laminated plate which is resistant to an impact when a frame is sandwiched between a glass plate and a polycarbonate (hereinafter abbreviated as “PC”) plate and whose surface is not easily worn.

[0002]

2. Description of the Related Art Generally, commercially available transparent plates are all made of glass or PC plates.

[0003]

However, the above-mentioned transparent plate has the following drawbacks. Those made of glass have a good surface hardness (reaching a hardness of 7H) and a good light transmittance, and the hardness is high, so that the surface is hard to be worn. However, since it has a low toughness and is easily cracked when an external force is applied, if it is used in a general high risk, it is easily cracked when a higher impact force is applied and a danger is likely to occur. Regarding the above-mentioned drawbacks, generally, safety glass has an increased thickness, or a fireproof glass is used to reduce the risk thereof, but the manufacturing cost is increased.

The transparent plate set made of PC can withstand higher impact force (250 times higher than tempered glass), but its surface hardness is only 0.5H, so the surface is abraded. easy. In order to achieve the purpose of safety and aesthetics, the general gem display box is generally made of tempered glass, but if it is stolen, it will be destroyed if an external force shocks it, so it is almost safe. In addition, since the exhibition space is illuminated for a long time, there is a large temperature difference between the inside and outside of the exhibition box, and water vapor tends to condense.

When machining parts in a machine shop, for example on lathes or CNC machining machines, appropriate protective masks are generally provided at appropriate points to prevent the scattering of metal chips. An observation window is provided at an appropriate portion of the protective mask, and an operator grasps the processing state through the observation window. This observation window is generally provided with one tempered glass, but if the parts on the lathe or the cutting tool are not firmly pinched, the tempered glass will be destroyed, and if it jumps out, an accident may still occur. Further, when the machine tool is cut for a long time, hot air is generated inside the machine, and the protective mask cannot clearly see the machining status inside the machine due to the temperature difference between the inside and outside.

Therefore, an object of the present invention is to provide a reinforced laminated plate having high impact resistance and reduced surface wear.

[0007]

In the reinforced laminated board according to claim 1 of the present invention, a frame is sandwiched between a glass plate and a PC plate which correspond to each other, and the frame has a hollow shape. It has a hollow portion, and the desiccant can be filled in the hollow portion. The frame body has an inner edge surface and an outer edge surface facing the inner edge surface, and a plurality of holes communicating with the hollow portion are formed in the inner edge surface of the frame body.
The size of the frame is smaller than the glass plate and the PC plate, and the outer edge surface of the frame forms a recess between the glass plate and the PC plate. The concave portion is filled with a soft and elastic colloid, and the frame body, the glass plate and the PC plate are bonded together.

In the reinforced laminated plate according to the second aspect of the present invention, the outer edge surface of the frame body extends outward to form a convex shape. In the reinforced laminated board according to claim 3 of the present invention, the surface where the glass plate, the PC plate and the frame are joined is a flat surface. The reinforced laminated board according to the fourth aspect of the present invention may be manufactured into an arcuate surface by bending a desired different shape or size according to different needs of the glass plate and the PC plate.

[0009]

1 to 4 show a reinforced laminated board according to an embodiment of the present invention. The frame body 30 is sandwiched between the glass plate 10 and the PC plate 20 which face each other in the strengthened assembled plate. In this embodiment, the glass plate 10 is made of tempered glass, and the surface where the glass plate 10, the PC plate 20 and the frame body 30 are joined is a flat surface. Glass plate 10 and P
The C plate 20 is separated from the C plate 20 by the frame body 30 at the distance of the frame body 30. The frame 30 is hollow and has a hollow portion 31, and the hollow portion 31 can be filled with a desiccant 40. The frame body 30 has an inner edge surface 32 and an outer edge surface 33 that faces the inner edge surface 32. The outer edge surface 33 extends outward and is formed in a convex shape. A plurality of holes 34 communicating with the hollow portion 31 are formed in the inner edge surface 32 of the frame body 30. The size of the frame body 30 is smaller than that of the glass plate 10 and the PC plate 20, and the outer edge surface 33 of the frame body 30 has a recess 3 between the glass plate 10 and the PC plate 20.
5 is formed. The concave portion 35 can be filled with a flexible and elastic colloid 50. As the colloid 50, for example, thermosol or silicon is used, and the frame body 30, the glass plate 10 and the PC plate 20 are joined together.

The hollow portion 31 of the frame body 30 can be filled with a desiccant 40, and the inner edge surface 32 of the frame body 30 has a plurality of holes 34.
Is formed and communicates with the space formed between the glass plate 10 and the PC plate 20, the air between the plates is dried by the desiccant 40, and the condensation of water vapor is prevented.

Further, since the outer edge surface 33 of the frame 30 has a convex shape, the contact area between the outer edge surface 33 and the colloid 50 can be increased to improve the adhesive effect. In addition to the specific examples described above, the PC plate 20 or the glass plate 10 may be formed into different shapes and sizes with different safety designs, or may be formed into curved surfaces.

This embodiment has the following effects. Since one surface of the reinforced laminated plate is the PC plate and the other surface is the reinforced glass, the impact resistance of the reinforced laminated plate is very excellent. The test results are shown below. (Ii) Plate thickness 3 by impact strength test (ASTM D256A)
12-16ft-lb / in when performing "V" type impact test in mm
And a non- "V" type impact test with a plate thickness of 3 mm yields 60 ft-lb / in.

(B) Depending on the ball drop impact strength, the plate thickness is set to 6 mm, and a ball of φ25 mm and a weight of 5 lb is set to 4 mm.
200ft-lb / when free-falling from a height of 0 feet
is in. (Ha) The impact resistance of PC board is 250 times larger than that of tempered glass. The other side of this tempered transparent plate set is tempered glass, and the surface hardness of tempered glass is excellent (reaching hardness of 7H) and the light transmittance of the surface is high, but when it receives a larger impact force, it breaks. Easy and dangerous, but PC
The advantage of the plate is that it can withstand higher impact force (250 times higher than tempered glass), but its surface hardness is only 0.5
Since the surface is H, the surface is easily worn. If these two kinds of plates are set as a set, the surface can be prevented from being worn, a larger impact force can be endured, and the safety requirement can be achieved.

As shown in FIG. 4, when tempered glass having good hardness is used as a surface layer and a shock-resistant PC plate is used as a back layer, the following advantages can be obtained. When an impact of an external force is received, for example, at a CNC work site, the workpieces on a lathe or the cutting tools on a milling machine are not firmly pinched, and they can jump out during machining, resulting in a considerable impact force. . At this time, it is possible to break the tempered glass plate of the tempered transparent plate set of the present invention, but the PC plate only needs to be dented due to impact resistance, and a protective film that can protect the workpiece and cutting tool that just jumped out Since it is formed, it has a safety protection effect.

The frame is composed of a tempered glass plate and a PC which correspond to each other.
It is sandwiched between the plates and has a hollow portion, and a plurality of holes are provided on the inner edge surface of the frame body, the desiccant fills the hollow portion, and the desiccant penetrates the holes to form a glass plate. The dryness of the air between the PC plates can be maintained, and the condensation of water vapor can be prevented by the temperature difference between the inside and the outside of the strengthened transparent plate set.

Since the size of the frame is slightly smaller than the tempered glass plate and the PC plate, one recess is formed between the outer edge surface of the frame and the strengthened glass plate and the PC plate, and a thermosol or silicon is used to form the recess. Since the thermosol and the silicone are soft and have elasticity, a packing that can absorb and absorb a small amount of vibration and can be buffered can be formed after adhering to absorb a sudden external force impact.

As shown in FIG. 5, since the frame body is sandwiched between the tempered glass plate and the PC plate, a gap is maintained between the two plates and the tempered glass is subjected to an external force.
The gap first absorbs the impact force and has a cushioning effect. Since the frame is sandwiched between the tempered glass plate and the PC plate, when the sound wave hits it, the noise can be reduced through the actions such as reflection, absorption, and transmission, and the sound wave is generated by the glass. The PC board is reached via the board and a sealed air layer. Therefore, the noise isolation effect of the PC board is extremely excellent, and the noise is sufficiently isolated, so that the PC board has an extremely excellent noise isolation effect. Since the design can be flexibly changed, it can be bent into different sizes or various different shapes according to different needs, and the requirements for practical use and aesthetics can be achieved.
