Description

[Detailed Description of the Invention] The present invention relates to a building block with windows for lighting that is lightweight, has lighting properties, and has improved heat insulation properties.

Conventionally, this type of block has a window hole penetrated from the front side to the back side in the approximate center thereof, and two glass plates are placed in the window hole with an appropriate space between the glass plates. By opening and extending the window hole, it was possible to provide daylight without impairing the insulation properties of the window hole, but in this case, since the outer periphery of the window hole in the block is made of cement mortar, It is heavy and difficult to handle when transporting it, and cement mortar has poor insulation properties, so the insulation of the outer periphery of the block is poorer than that of the window holes, and as a result, the insulation of the block as a whole is insufficient. I couldn't say yes.

In the present invention, a window hole penetrating from the front side to the back side is provided approximately at the center of the block piece, and a transparent material is stretched in the middle part of the window hole in the depth direction. On the back side, a recessed part opening into this is formed so as to surround the window hole, and these block pieces are made into a pair, and the pair of block pieces is coated with a heat-resistant light-transmitting material at the window hole location of both block pieces. With the boards sandwiched together, they are glued back to back to each other so that the recess becomes an independent sealed hollow part within both block pieces, and the inside of the sealed hollow part is sealed in advance from the surface side of the building block. To provide a building block with a window for lighting, which is lightweight, has lighting property, and has improved heat insulation property by installing a heat insulating material so as to partition the block from the back side.

Next, the present invention will be explained based on the drawings. Reference numeral 1 denotes a building block made of a fire-resistant heat insulating material such as cement mortar, and the building block 1 is made up of a pair of block pieces 1' and 1', which will be described later. ing.

Reference numerals 1' and 1' denote a pair of block pieces, and each block piece 1' has a window hole 2 penetrated from the front side A to the back side B in the approximate center thereof.

In this embodiment, the window hole 2 is formed in a tapered shape that widens from the back side B to the front side A of the block piece 1', as shown in FIG.

3 is an uncolored or colored transparent material such as organic glass such as polymethyl methacrylate, unsaturated polyester, or polystyrene, or inorganic glass. In this example, the transparent material 3 is dish-shaped and has a The transparent body 3 is integrally provided with an outer peripheral edge 4 that can come into contact with the inner wall surface of the window hole 2, and the transparent body 3 is stretched so as to cover the middle part of the window hole 2 in the depth direction. The outer peripheral edge 4 of the light body 3 is fixed to the inner wall surface of the window hole 2 with adhesive or the like.

5 is open on the back side B of each block piece 1',
In addition, a recess is formed on the outer periphery of the window hole 2 of each block piece 1' so as to surround the window hole 2, and the recess 5
In this embodiment, each block piece 1' is tapered toward the front side A of the block piece 1'.

The pair of block pieces 1', 1' are placed back to back with the heat-resistant transparent plate 7 sandwiched between the two window holes, and the end surfaces of the outer peripheral edges of the back sides of the pair of block pieces 1', 1' are aligned with each other. By bonding the back end surface of each block piece 1' and the outer peripheral surface of the heat-resistant transparent plate 7, the recesses 5, 5 in both the block pieces 1', 1' are separated from the window hole 2. It is formed into an independent sealed hollow part 8. Prior to the adhesion, a heat insulator is installed in the recess 5 of either one of the pair of block pieces 1', 1' to partition the sealed hollow part 8 into a front side A and a back side B of the block piece 1'. This is to fix the material 6.

The building blocks 1 with lighting windows constructed in this way can be used for building exterior walls of rooms in buildings, etc. by inserting reinforcing bars between the blocks and stacking them up while filling the joints, similar to conventional concrete blocks. A wall constructed in this way receives light from the window holes 2 of each block 1, so there is no need to attach glass windows to the wall.

Incidentally, when making the block piece 1', the strength of the block 1 can be significantly improved if fibers such as glass or asbestos are mixed into a fireproof heat insulating material such as cement mortar.

Further, instead of the above embodiment, the heat insulating materials 6, 6 may be stretched in the recesses 5, 5 of the pair of block pieces 1', 1' in the same manner as described above, and the block pieces 1'
It goes without saying that a concave portion 5 partitioned by a rib may be provided at the outer peripheral portion of the window hole 2 so as to surround the window hole 2 and open on the back side B of the block piece 1'. do not have.

In summary, the present invention consists of a pair of block pieces made of a refractory heat insulating material such as cement mortar, etc. Each block piece has a window hole penetrating from the front side to the back side in the approximate center of the block piece. A translucent material is stretched over the window hole in the middle of the depth direction, and a recessed portion opening into the recess is formed on the back surface of the block piece so as to surround the window hole, and a recessed portion is formed in the back surface of the block piece so as to surround the window hole. A heat-resistant transparent plate is sandwiched between the window holes of the blocks, and the blocks are bonded back to back, so that the concave portion becomes an independent sealed hollow portion within the pair of blocks. A heat insulating material is provided in the recess of one or both of the pieces to partition the sealed hollow part into the front side and the back side of the block piece. Light can be let in through the hole, and it is lightweight because a sealed hollow space is formed inside the outer periphery of the window hole.In addition, there is a sealed hollow space inside the outer periphery of the block that is independent of the window hole and that surrounds the window hole. Since a hollow part is formed and the hollow part is partitioned into the front side and the back side of the block with a heat insulating material, the heat insulation of the outer periphery of the block is significantly improved, and the window hole of the block is
It is partitioned by two transparent bodies and one heat-resistant transparent plate, and the space between the heat-resistant transparent plate and each transparent body, that is, the front side and the back side with the heat-resistant transparent plate in between. Since a sealed space is provided in each of the blocks, the heat insulation properties of the window holes are also improved, and the combination of the two has the effect of significantly improving the heat insulation properties of the entire block.
