Description

[Detailed description of the invention]

[Field of Industrial Application] The present invention relates to glass blocks and the construction structure of glass blocks, and more specifically, when constructing walls of buildings, small glass members in the shape of a rectangular parallelepiped, that is, glass blocks are stacked together to form a wall surface. The present invention relates to a glass block used in a method for constructing a glass block, and a construction structure for constructing a glass block wall surface using this glass block.

2. Description of the Related Art Conventionally, glass blocks have been widely used to construct wall structures that have practical effects such as heat insulation and soundproofing, and high interior design. Glass blocks are constructed by stacking rectangular parallelepiped glass blocks, filling the gaps between the glass blocks with mortar, etc., and joining the glass blocks together to form a wall with glass blocks arranged vertically and horizontally. Ta.

[0003] Glass blocks have the disadvantage of being brittle and easily broken, and if excessive stress or distortion is generated during construction of the glass blocks, there is a problem that the glass blocks will be damaged. Therefore, in order to absorb the stress mentioned above, gaskets are installed between the glass blocks, but even so, it is necessary to prevent the stacking of glass blocks from bending or distorting.
There were problems in that it had to be constructed extremely carefully, required high technical ability and skill from the workers, and took a long time to construct.

[0004] Furthermore, wall structures made of glass blocks must also have mechanical resistance against external factors, which is required for building wall structures. It is necessary to install reinforcing measures such as arranging reinforcing bars in the gaps and filling and sealing the gaps with mortar, which also requires time and effort when constructing glass blocks. It was the cause.

In order to solve the above-mentioned problems in glass block construction, a glass block or glass unit has been proposed as disclosed in Japanese Patent Publication No. 1-29944. FIG. 13 shows the structure of the glass unit of the above-mentioned prior art. On the outer periphery of the glass block main body G, which has a rectangular parallelepiped shape similar to conventional glass blocks,
It is formed by integrating a square frame-shaped frame F, and on each side of the frame F, there is a fitting uneven part is provided. By stacking the glass units vertically and horizontally and connecting the fitting uneven parts X and X formed on the sides of adjacent glass units to each other, the glass units are automatically and accurately positioned. , are accumulated. Note that the fitting uneven portions X of the frame F are formed in the same shape on all four sides, so in order to fit and connect the fitting uneven portions X, X of adjacent glass units, it is necessary to The front and back sides are arranged alternately, and the adjacent fitting concave and convex portions X are connected so that the concave and convex portions of X are opposite to each other.

[0006] According to this glass unit, the positioning of the glass units can be easily and accurately set by the above-mentioned fitting structure, so compared to conventional glass blocks,
Construction is easy and efficient, and the finish is also good. It does not require a high degree of technical ability or skill from the worker. In addition, the glass units are mechanically and firmly connected by the above-mentioned fitting structure, so the mechanical strength and durability required for the wall structure can be ensured sufficiently, and unlike conventional glass blocks, there can be no gaps between the glass units. It is said to have the advantage of eliminating the need for troublesome work such as inserting reinforcing bars between them and sealing them with mortar.

[0007]

[Problem to be Solved by the Invention] However, if a wall structure made of glass blocks is to have high structural strength and durability, or to increase safety, reinforcement with reinforcing bars becomes necessary. In the glass units of the prior art described above, there was a problem in that it was impossible to arrange reinforcing bars because the fitting unevenness of the frame existed in the connecting portions between the glass units.

In the glass units of the prior art, the glass units are connected to each other only by the fitting action of the fitting unevenness X of the frame F, so that all the external force applied to the glass wall structure is absorbed by the fitting unevenness. The load will be placed on part X. No matter how strong a material is used for the frame F,
It is not possible to significantly increase the strength of the joint between the fitting uneven parts Why is it inferior in strength compared to placing reinforcement?

Therefore, even in the glass unit of the prior art, it would be sufficient if reinforcing bars could be arranged inside, but as can be seen from FIG. Since the uneven portions X and X are provided, there is no space provided for arranging reinforcing bars. As a result, the glass block wall structure using this glass unit had the disadvantage that the structural strength could not be increased very much and the durability was also poor.

Furthermore, in the conventional glass block wall structure, an illumination mechanism is built inside or between the glass blocks, and the illumination mechanism is turned on by being energized from an external power source. Although a wall structure has been proposed, in order to construct such a glass block wall structure with lighting, it is necessary to run wiring for lighting inside the glass block wall structure. However, in the glass unit provided with the fitting structure as in the prior art, there is no space for the wiring to pass through, so it is not possible to construct a glass block wall structure with lighting.

[0011] Therefore, an object of the present invention is to further improve the glass unit of the prior art, so that reinforcing bars and wiring can be passed inside the glass block wall structure, thereby increasing the structural strength and improving durability. The purpose of the present invention is to provide a glass block that can improve safety and incorporate a lighting mechanism within the wall structure. Another object of the present invention is to provide a construction structure that can be constructed simply and with a good finish using such glass blocks.

0012

[Means for Solving the Problems] A glass block according to the present invention which solves the above problems is composed of a glass block main body and a polygonal annular frame surrounding the outer periphery of the side surface of the glass block main body. In a glass block having a fitting uneven part on the side for connection, a groove extending over the entire length of the side is formed on the surface of the fitting uneven part, and the glass blocks can be fitted together at the fitting part of the frame. When the frames are connected together, a through space is formed by the recessed groove on the opposing surface of the fitting uneven portion of the adjacent frame bodies.

[0013] The glass block main body can be made of the same material and structure as a normal glass block. The outer shape of the glass block body is a thick rectangular parallelepiped with a square front view, or other polygonal three-dimensional shapes. The frame is made of inorganic materials such as cement and concrete, metal, synthetic resin, wood, and other ordinary building structural materials. Excluding the back side,
It has a polygonal ring shape that surrounds the upper, lower, left, and right sides. The frame body can be simply fitted to the glass block body, or it can be glued or engaged with an appropriate engagement part,
They can also be integrally joined by fixing them using fasteners.

[0014] The outer periphery of the frame is provided with fitting concavo-convex portions for connection on each side. The shape of the mating uneven portion is basically the shape of the fitting unevenness in various ordinary construction members consisting of protrusions and grooves, or protrusions and holes, etc., which are used in the glass units of the prior art described above. The shape of the part can be adopted. If a female or concave fitting part is formed on one side of the upper and lower or left and right opposing sides of the frame, a male or convex fitting part is formed on the other side. It is preferable to form fitting concave and convex portions with opposite concavities and convexities, such as forming a fitting portion having a shape. In this way, glass blocks of the same shape can be freely connected vertically and horizontally while keeping the front and back sides in the same direction, without having to take the trouble of arranging the front and back sides alternately. However, if male and female mating concave and convex portions of the same shape are formed on all sides of the top, bottom, left and right, and these are arranged alternately on the front and back to connect them, or if the glass has only a mating concave portion. It is also possible to alternately connect blocks and glass blocks having only fitting projections. Further, one or more sets of fitting protrusions and fitting recesses are provided side by side on one side of the frame, and similar fitting protrusions and fitting recesses are provided on the side opposite to the side. of,
Even if the arrangement is reversed, the glass blocks can be connected to each other without changing the front and back sides.

[0015] Recessed grooves are formed on the surface of the fitting uneven portion. The recessed groove is continuously formed over the entire length of one side. The recessed groove may be provided in any portion of the fitting uneven portion, such as the top surface of the convex portion or the valley surface of the recessed portion. The shape of the recessed groove can be freely set according to the diameter and shape of the reinforcing bars, electric wires, and other objects to be inserted into the recessed groove. The position and number of grooves to be formed can also be freely set depending on the purpose and use. For example, the cross-sectional shape of the recessed groove can be semicircular, U-shaped, square, trapezoidal, triangular, or other shapes. However, the recessed groove needs to be provided at a position that does not interfere with the fitting and connecting function of the fitting uneven portion.

[0016] When the glass blocks are fitted and connected to each other by the fitting uneven portions, on the opposing surfaces of the fitting uneven portions, the surfaces of the fitting uneven portions contact each other without a gap in the portions other than the recessed grooves; At the location where the groove is formed, a through space is formed that is surrounded by the surface of the mating groove and the mating groove, or is surrounded by the grooves facing each other. The fitting concavo-convex portions that are fitted and connected to each other may have the same number of grooves formed and the same formation position, or may have different numbers of grooves formed or positions at which they are formed. However, if the recessed grooves of the fitting concavo-convex portions that are fitted and connected to each other are connected to form one through space, the through space can be made larger.

[0017] The penetrating space is formed by arranging any linear or rod-shaped member inside the glass block wall structure, such as reinforcing bars made of reinforcing bars, or the above-mentioned wiring for lighting, wiring for audio equipment such as speakers, etc. It can be used for. In order to place reinforcing bars, it is necessary to provide a penetration space that runs through the entire glass block wall structure vertically and horizontally, but if you just want to run the power supply wiring for lighting, you can connect the lighting system from outside the wall structure. Penetration spaces may be provided only at the locations where they communicate. In addition, the arrangement of the penetrating space can be changed freely according to the purpose of use and the structure of the wall.

[0018] The glass block having the above structure connects the glass blocks to each other by fitting the fitting uneven portions provided on the sides of each frame body in the same way as ordinary glass blocks. , stack the glass blocks side by side horizontally and vertically to construct the desired glass block wall structure. At the connection points between glass blocks, it is sufficient that the fitting uneven parts are simply fitted to each other, but it is possible to connect the connecting points by gluing the contact surfaces of the fitting uneven parts or by filling and hardening mortar etc. It is preferable to firmly join them together. Since the end face of the frame body is exposed between adjacent glass blocks, the end face of the frame body may be finished as a kind of pattern or design in an exposed state,
Appropriate joint material or decorative material made of rubber, plastic, etc. may be attached to the front surface of the frame.

[0019] Next, the construction structure of the glass block according to the present invention includes an outer frame body that is attached and fixed to a building structure surrounding the outer periphery of the construction range of the glass block, and a frame body that is fitted vertically and horizontally in the inner space of the outer frame body. The outer frame comprises the glass blocks according to claim 1, which are laid in a connected manner, and reinforcing bars which are inserted into the through space formed between the adjacent glass blocks and whose both ends are attached and fixed to the outer frame body. The body consists of a hollow frame material with a rectangular cross section consisting of an outer side, an inner side, and left and right sides.The outer side is fixed to the building structure with mounting screws, and the inner side opposite to the mounting position of the mounting screw is is provided with an opening for operating the mounting screw, and a locking hole is provided on the inner side for inserting and locking a locking nut screwed into the end of the reinforcing bar. An opening for operating the locking nut is formed on the side at a position corresponding to the attachment point of the locking nut.

The outer frame body is made of a hollow frame material made of steel, aluminum, synthetic resin, or the like, and has a rectangular cross section consisting of an outer side, an inner side, and left and right sides. This hollow frame material is installed in the shape of a rectangular frame along the outer periphery of the construction surface, that is, along the inner surface of the architectural structure. To attach and fix the outer frame to the building structure, use mounting screws. In order to rotate the mounting screw, an opening for operating the mounting screw is provided on the inner surface of the outer frame at a position opposite to the mounting position of the mounting screw. The shape and size of the opening are set according to the structure of the mounting screw and the structure of a tool such as a driver for operating the mounting screw.

[0021] The inner surface of the outer frame may be provided with a fitting uneven portion for fitting and connecting the side edges of the glass block. Further, the fitting uneven portion may not be provided on the inner surface of the outer frame, and a spacer, a holding frame, or the like may be used to fill in the space between the inner surface of the outer frame and the fitting uneven portion of the glass block. The reinforcing bars are made of the same steel material as in conventional glass block wall structures, and have a male thread cut on at least one end.
A locking nut is screwed into this male thread. This locking nut is attached and fixed to the inner side of the outer frame body, and a reinforcing bar is attached. The ends of the reinforcing bars on which the locking nuts are not screwed may be fixed to the outer frame using various fixing means used in ordinary reinforcing bar construction.

A locking hole through which the locking nut is inserted and locked is provided on the inner side of the outer frame. The locking hole has a size that allows the locking nut to be inserted therethrough, and a portion of the locking nut can be locked to the edge of the locking hole. The specific shape of the locking hole is, for example, an insertion part that is larger than the outside diameter of the locking nut, a cut formed on the edge of the insertion part, and a hole that is smaller than the outside diameter of the locking nut but outside the reinforcing bar. It is preferable to have a notch larger than the diameter. .

When the locking nut of the reinforcing bar is inserted into the locking hole of the outer frame and the locking nut is rotated, the reinforcing bar is drawn into the outer frame. If the opposite end of the reinforcing bar is fixed, the reinforcing bar will be tightened and fixed under tension. If locking nuts are screwed into both ends of the reinforcing bars, you can rotate both locking nuts to tighten the reinforcing bars, or leave one locking nut fixed and tighten the other locking nut. It is sufficient to rotate only the locking nut. To rotate the locking nut, on either the left or right side of the outer frame,
An opening for operating the locking nut is provided at a position corresponding to the mounting position of the locking nut. The position and shape of the operation opening are set according to the structure of the locking nut and the operation tool such as a spanner or wrench.

[0024]

[Operation] A recessed groove is formed on the surface of the fitting uneven part of the glass block, which extends the entire length of the side, so that when the glass blocks are fitted and connected at the fitting part of the frame, the adjacent frame If a through space is formed by the recessed groove on the opposing surface of the mating uneven part, the through space can be used to install reinforcing bars or insert lighting wires. You can Moreover, since there is no effect on the fitting connection function of the fitting uneven portion itself, all the effects of the glass block provided with the above-described fitting uneven portion can be satisfactorily exhibited.

[0025] As for the construction structure of the glass block, the outer frame body interposed between the glass blocks and the building structure that are fitted and connected vertically and horizontally is made of a hollow frame material with a rectangular cross section, and the outer frame made of this hollow frame material The construction of a glass block wall structure is possible by screwing the outer side of the body to the building structure and inserting and locking the locking nuts of the reinforcing bars into the locking holes formed on the inner side of the outer frame. Strength and durability can be increased, and the finish or appearance of the boundary between the glass block wall structure and the architectural structure can be improved.

However, the mounting screws that attach and fix the outer frame to the building structure and the locking nuts that attach and fix the reinforcing bars to the outer frame must be operated in the internal space of the outer frame made of hollow frame material. Until now, it has not been possible to operate from the outside of the outer frame made of hollow frame material. Therefore, if an opening for operating the mounting screw is provided on the inner surface of the outer frame and an opening for operating the locking nut is provided on either the left or right side, the mounting screw can be accessed from the outside of the outer frame. and locking nuts.

It shows the connection structure with. The figure shows a structure in which the lower side of the glass block 1, that is, the side of the frame 20 in which the fitting recess 24 is formed, is connected to the outer frame 30a on the lower side. The outer frame body 30a is made of a hollow frame material made of shaped steel material, shaped aluminum material, etc., and has a flat rectangular cross section. The outer side of the outer frame 30a is in contact with the inner surface of the building structure 9, and the mounting screws b1 are inserted from the inside of the outer frame 30a and fixed to the building structure 9 with screws. Outer frame body 30
An operating opening 32 having a circular shape or the like is formed through the inner side of a so that the internal mounting screw b1 can be rotated with a screwdriver or the like.

[0036] A fitting convex portion 31 protruding from the surface is provided on the inner side of the outer frame body 30a. This fitting convex portion 31
Then, the fitting recess 24 of the glass block 1 is fitted and connected. If this fitting part is joined with adhesive, the connection can be made more securely. Reinforcing bars 40 are attached and fixed to the inner side of the outer frame 30a. The reinforcing bars 40 are made of steel bars or the like.
External threads 42 are cut only at a certain length at both ends. A locking nut 44 is screwed into the male thread 42 at one end of the reinforcing bar 40 . The locking nut 44 on this side may be simply rotatably screwed into the male thread 42, but the locking nut 44 may also be caulked to the male thread 42 or fixed by welding or the like. Also, this part has 4 male screws.
2, a locking member larger than the outer diameter of the reinforcing bar 40 may be fixed to the end of the reinforcing bar 40 by welding or the like.

FIG. 8 shows a structure for attaching the reinforcing bars 40 to the outer frame 30a. A locking hole 34 is formed through the inner side of the outer frame 30a. The locking hole 34 has a circular insertion portion 35 that is larger than the outer diameter of the locking nut 44, and a U-shaped notch that is smaller than the outer diameter of the locking nut 440 but larger than the outer diameter of the reinforcing bar 40. It consists of a section 36. The two notches 36 extend symmetrically from the edge of the insertion part 35 at a constant angle. Left and right notches 36
The distance between the tips of the above-mentioned central pair of concave grooves 23
, 23 or 26, 26.

To attach the reinforcing bar 40 to the outer frame body 30a, the locking nut 44 is screwed into the end of the reinforcing bar 40, and then the locking nut 44 is inserted into the outer frame body through the insertion portion 35 of the locking hole 40. Insert it inside 30a. Next, reinforcing bar 40
When is moved from the insertion part 35 to the back of the notch part 35,
Since the locking nut 44 is caught on the inner edge of the locking hole 40,
The reinforcing bars 40 cannot be pulled out.

With the above-described mounting structure, all the mounting structures such as the mounting screw b1 and the locking nut 44 are housed inside the outer frame 30a, so these structures are not exposed to the outside. It looks good in appearance. In the above explanation, the lower side of the glass block 1 is attached to the outer frame 30a placed at the lower end of the construction surface, but the right side of the glass block 1 equipped with the fitting recess 24 of the same structure is A similar structure is also employed when attaching to the frame 30. Therefore, in FIG. 5, of the outer frame 30 arranged in a rectangular frame shape, the outer frame 30a having the fitting convex portion 31 formed on the inner side is arranged on the lower side and the right side. do.

Next, FIGS. 9 and 10 show a structure in which the upper side or left side of the glass block 1 is attached to the outer frame 30. In this case, an outer frame 30b having a partially different structure from the outer frame 30a is used. Outer frame body 30
The outer side of b is attached and fixed to the building structure 9 with the mounting screw b1 in the same manner as the case of the outer frame 30a, and the operation opening 32 of the mounting screw b1 is also provided on the inner side of the outer frame 30b.
is formed through it. Furthermore, a locking hole 34 similar to that shown in FIG. 8 is formed through the inner surface of the outer frame 30b, and a locking nut 44 of the reinforcing bar 40 is inserted and locked therein.

Upper outer frame 30a and lower outer frame 30b
, or the outer frame body 30a on the left side and the outer frame body 30b on the right side
In between, reinforcing bars 40 are arranged vertically and horizontally, and locking nuts 44 at both ends are locked to the respective outer frames 30a and 30b. In this state, no tension force is introduced into the reinforcing bars 40, and the reinforcing function for the glass block 1 cannot be exerted, and the reinforcing bars 40 are shifted from the cutout part 36 of the locking hole 34 toward the insertion part 35. , the locking nut 44 is connected to the locking hole 34
There is a possibility that it will come off. Therefore, the locking nuts 44 at either or both ends of the reinforcing bars 40 are rotated to attract and tighten the reinforcing bars 40 to the outer frames 30a, b, thereby introducing tension to the reinforcing bars 40. The reinforcing bars 40 are securely fixed to the outer frames 30a and 30b.

Therefore, as shown in FIG. 10, the outer frame body 30b on the upper and left sides has a mounting position for the locking nut 44, that is, either the left or right side that is lateral to the position where the locking hole 34 is formed. A rectangular opening 38 is formed through the side. The locking nut 44 can be rotated by inserting a spanner or the like through the opening 38 from the outside of the outer frame 30b.

The opening 38 for operating the locking nut 44 may be formed on either the left or right side of the outer frame 30b, which is convenient for operating the locking nut 44.
It may be formed on both the left and right sides. In addition, even if the operation opening 38 is provided in one of the outer frames 30b and 30a disposed facing each other, and only the locking nut 44 on this side is rotated, the reinforcement 40 can be tightened, but there is no operation opening 38 in the other outer frame 30a.
may be provided.

[0044] No fitting convex portion is formed on the inner side of the outer frame body 30b, and it is flat. A thin spacer 62 having the same width as the fitting projection 22 is installed between the fitting projection 22 of the glass block 1 and the outer frame 30b. The spacer 62 is provided with an insertion hole or an insertion groove through which the reinforcing bar 40 is inserted, or the spacer 62 is installed intermittently avoiding the location where the reinforcing bar 40 is placed.

[0045] A generally L-shaped holding frame 60 is attached to both sides of the fitting convex portion 22 and the spacer 62. The spacer 62 and the holding frame 60 are made of synthetic resin, aluminum profile, or the like. The holding frame 60 is arranged so as to cover the inner side and the outside of the side sides of the outer frame body 30b, and the mounting screw b2 is inserted into the outer frame body 30 from the outside of the holding frame 60.
b to fix the holding frame 60. Holder frame 6
A decorative plate 52 is adhered to the side surface of the 0 to hide the mounting screw b2. The operation opening 38 of the locking nut 44 provided on the side of the outer frame body 30b is also covered and hidden by the holding frame 60 and the decorative plate 52, so that it is not exposed to the outside.

In the above embodiment, the fitting convex portion 22 of the glass block 1 is fitted into the concave portion formed by the spacer 62 and the holding frame 60, but the outer frame 30
It is also possible to form a fitting recess directly on the inner side of b. However, in this case, the opposing outer frame body 30
It becomes difficult to insert and attach the glass block 1 between a and 30b without leaving a gap. That is, in order to connect by concave-convex fitting, there must be a gap that allows the mating concave-convex parts to move in the direction facing each other, so it is not possible to spread the glass blocks 1 between the outer frames 30a and 30b without any gaps. It is.

On the other hand, the spacer 62 and the holding frame 60
When interposed between the outer frame body 30b and the glass block 1, the above problems are solved. That is, FIG.
As shown in the figure, when stacking the glass blocks 1 one after another from bottom to top and fittingly connecting the last glass block 1 to be connected to the outer frame 30b to the glass block 1 below it, the spacer 62 The holding frame 60 is not attached. In this state, between the lower glass block 1 and the outer frame 30b, the fitting uneven portion 22 of the glass block 1,
There is a gap L wider than the total height including 24. Therefore, if the last glass block 1 is inserted into the gap and the fitting recess 24 on the lower side of the glass block 1 is fitted into the fitting protrusion 22 of the lower glass block 1, the glass block 1 can be easily fitted and connected. In this state, there will be a gap between the upper end of the glass block 1, that is, the top surface of the fitting convex portion 22, and the lower side of the outer frame body 30b, so the spacer 62 is attached here.

In this way, the decorative board 52 can be attached simply by fitting the engagement projections 54 of the decorative board 52 into the engagement holes 61 of the holding frame 60. In addition, the outer frame body 30
When the engagement protrusion 54 of the decorative board 52 comes into contact with the side of the outer frame 30b, a relief hole 39 into which the engagement protrusion 54 is inserted may be provided on the side of the outer frame 30b.

In each of the above-described embodiments, attachment of reinforcing bars 40 and It becomes easier to attach the glass block 1. Specifically, the insertion part 35 of the locking hole 34 is arranged in the advancing direction of fitting and connecting the glass blocks 1,
Preferably, the notch 36 is arranged in the opposite direction.

For example, in the construction procedure shown in FIG. 5, for the vertical outer frames 30a and 30b, the glass blocks 1 are stacked from bottom to top, so the insertion part 35 faces upward and the cutout part 36 faces downward. The locking hole 34 is arranged in such a manner that it faces. Then, glass blocks 1 and 1 are lined up in a row.
When installing the horizontal reinforcing bar 40 on top of..., first insert the reinforcing bar 40 into the insertion part 35, and it will be inserted smoothly without getting caught on the upper end of the glass block 1... (The state of the reinforcing bars 40a indicated by the two-dot chain line in FIG. 5). After that, the reinforcing bar 40 is inserted into the insertion portion 3.
5 toward the notch 36, the reinforcing bar 40 is smoothly inserted into the groove 23 of the glass block 1.

Furthermore, in the horizontal outer frames 30a and 30b, the glass blocks 1 are arranged from right to left, so that the insertion portions 35 face to the left and the notches 36 face to the right. A locking hole 34 is arranged in advance. When inserting and attaching the glass block 1 between the plurality of reinforcing bars 40 arranged in the vertical direction, the reinforcing bars 40 that will be on the outside when inserting the glass block 1 are temporarily inserted into the insertion portion 35. The reinforcing bars 40b are pushed away toward each other to increase the gap between the reinforcing bars 40 and the adjacent reinforcing bars 40 (the state of the reinforcing bars 40b indicated by the two-dot chain line in FIG. 5). After inserting the glass block 1 into this gap and fittingly connecting it with the adjacent glass block 1 or the outer frame 30a, if the reinforcing bar 40 is pushed back from the insertion part 35 toward the notch part 36, the reinforcing bar 40 is inserted into the glass. Recessed groove 23 of block 1
inserted into.

[Effects of the Invention] According to the glass block according to the present invention as described above, the glass blocks can be sequentially fitted and connected using the fitting uneven portions provided on the sides of the frame. , Glass block walls can be constructed with very simple work and a good finish. Moreover, a groove is formed on the surface of the mating uneven part, and when the glass blocks are fitted and connected, a through space is formed on the opposing surface of the mating uneven part, so this through space can be used. This makes it possible to insert reinforcing bars such as reinforcing bars and to run wiring for built-in lighting.

As a result, glass block walls can be constructed with extremely simple work, and various functions can be added, such as reinforcing the glass block walls with reinforcing bars, improving durability, and incorporating built-in lighting and audio equipment. The performance and functionality of glass block walls can be improved, making it possible to construct glass block walls with superior functions that are impossible to achieve with conventional glass blocks.

Next, according to the construction structure of the glass block according to the present invention, a glass block having the above-mentioned excellent features is used, and there is a gap between the construction surface of the glass block wall and the surrounding architectural structure. The outer frame is mounted and fixed, and glass blocks are laid in the inner space of this outer frame and reinforcing bars are placed, so it is possible to directly connect to the building structure.
Compared to installing glass blocks with mating uneven parts or fixing reinforcing bars, the work is much easier, and the glass block wall structure can be easily constructed in any part of the building structure. becomes possible. By arranging reinforcing bars and attaching glass blocks based on the outer frame, you can accurately set the spacing and position of reinforcing bars and glass blocks, simplify dimensioning, and improve construction efficiency. and the finish is also better.

In particular, the outer frame has openings for operating mounting screws for attaching and fixing the outer frame to the building structure, and openings for operating locking nuts for attaching and fixing reinforcing bars to the outer frame. Since these mounting structures can be hidden inside the outer frame made of hollow frame material, the external appearance can be improved, and the mounting screws can be inserted using the openings. Also, the locking nut can be operated freely, resulting in extremely good workability.

Since the glass blocks, reinforcing bars, and outer frame can all be attached and fixed by fitting or screwing, it is easy to disassemble the glass block wall once it has been constructed.
