Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a wall structure for a court used for ball games such as racketball and squash that utilize indoor walls.

Prior Art In this type of racketball court, etc.
As shown in Figure 1, the rooms surrounding the racketball court, etc. are constructed on two floors in total, and the portions of all or part of the four inner walls of the racketball court, etc. that correspond to the two floors or the first floor There are systems in which both floors or only the first floor can be used as a viewing room by constructing walls of transparent tempered glass 1 only in the portions corresponding to the windows.

Most of the conventional wall structures for racketball courts, etc. are applied to the portions of the four inner walls corresponding to the second floor, as shown in FIG.
The upper and lower ends of the transparent tempered glass 1 are temporarily fixed with double-sided tape to a fixture 15 attached to the ceiling A of the building and a fixture 15 attached to the side wall B, respectively, and then adhesively attached with a silicone resin 23. It was hot. When applied to the part corresponding to the first floor, the same method as above is applied to the fixture 15 attached to the side wall B of the building and the fixture 15 attached to the floor C at the upper and lower ends of the transparent tempered glass 1, respectively. It was attached by adhesive. In constructing this wall structure, each of the above-mentioned fixtures 15 is
is attached to the building in advance, and after the building is completed, the vertically erected transparent tempered glass 1 is temporarily fixed to each fixture 15 with double-sided tape, and then the silicone resin 2
3 filled the space between the transparent tempered glass 1 and each fixture 15.

However, the weight of one sheet of the same transparent tempered glass 1 is approximately 150 kg when the height is 3 m, the width is 1.5 m, and the thickness is 12 mm, and it is difficult to temporarily fix the transparent tempered glass 1 with the double-sided tape. There were problems with the adhesive strength and the risk of peeling, and there were other drawbacks such as the inability to adjust the glass mounting position. In addition, since the bonding using the silicone resin 23 is performed with the transparent reinforced glass 1 standing vertically, a lot of time and effort is required, such as curing until the silicone resin 23 hardens.

Moreover, the transparent tempered glass 1 as shown in FIG.
The silicone resin 23 alone supports the impact force when a player collides with the player from inside the court, and the force applied when a spectator presses the transparent tempered glass 1 as shown in FIG. ing. However, the conventionally used silicone resin 23 was developed to prevent the transparent tempered glass 1 from collapsing by absorbing vibrations caused by the impact force etc. in an elastic state without completely hardening. Adhesive strength was not sufficient. That is, as shown in FIGS. 3 and 4, there is a risk that the transparent tempered glass 1 may peel off from the respective fittings 15 due to impact force, etc., and there is a problem with safety during use.

Furthermore, in this wall configuration, the entire weight of the transparent tempered glass 1 is supported on its lower end,
If this continues, the transparent tempered glass 1 will inevitably bend under its own weight.

Therefore, in order to prevent this and increase the strength of the transparent tempered glass 1, a ribbed glass 16 whose edges are adhered to the coated outer surface of the transparent tempered glass 1 is vertically installed. I couldn't avoid the hassle of time.

Furthermore, FIGS. 5 and 6 show the attachment structure of the transparent tempered glass 1 and the ribbed glass 16 used for the back wall of the conventional court, but the L-shaped attachment fittings 17 are applied to both glasses 1 and 16. This is done by tightening the mounting bolts 18, respectively. In this case, in order not to leave any unevenness on the inner surface of the transparent tempered glass 1, a portion of the transparent tempered glass 1 corresponding to the head of the mounting bolt 18 is recessed, and the recessed portion and the head of the mounting bolt 18 are made concave. The gap was filled with silicon-filled resin 8 or the like. Although this construction method uses thick transparent tempered glass, it has the disadvantage that the important attachment parts become thinner and more likely to break.

Furthermore, as another example of the conventional structure, a wall structure in which transparent tempered glass 1 is suspended from the ceiling A of a building as shown in FIG. 7 has been considered. In this structure, the upper and lower two sheets of transparent tempered glass 1 are connected by a joint fitting 19, which is held and suspended by a clamp fitting 21 in a hanging mechanism 20 provided above a ceiling A. The fixture 15 attached to the floor C merely makes it impossible for the transparent tempered glass 1 to move inward and outward directions, and is designed so that the weight of the transparent tempered glass 1 is not applied to it itself.

According to this wall structure, there is no fear that the transparent tempered glass 1 will bend under its own weight. However, as mentioned above, the rib glass 16 is essential in order to unbendably connect the two upper and lower transparent tempered glasses 1 at the connection part and to withstand the impact force, etc.
As in the previous case, this resulted in an unavoidable increase in material costs and labor during construction.

Furthermore, it is quite difficult to construct this wall structure. In other words, a large-area, heavy-weight transparent tempered glass 1 is hoisted to a height of 6.1 m in the case of a racket court, for example, a method for fixing the same transparent tempered glass 1 until the silicone resin 23 hardens, and four at a time. Joint metal fittings 19 for glass sheets
It is not easy to make connections, and an increase in construction costs is unavoidable.

Furthermore, if the transparent tempered glass 1 breaks due to use or other reasons, it will be extremely difficult to replace it.

Purpose This invention was made in order to eliminate the above-mentioned defects in the wall structure of conventional racketball courts, etc., and its purpose is to shorten the construction time by making construction easier and faster. It is an object of the present invention to provide a new wall surface structure for a racket ball court, etc., which can reduce the cost of materials, labor, etc., and improve safety during use.

EXAMPLE The configuration of the wall structure of a racketball court embodying the present invention will be described below with reference to the drawings.

First, the first embodiment shown in Figs. 8 to 12 will be explained.
This figure shows a wall structure in which the first floor of each side wall is covered with transparent tempered glass. In the drawing, a large number of transparent tempered glasses 1 are installed vertically on the wall of the racket ball court, and each glass has a height of about 3 m, a width of about 1.5 m, and a thickness of about 12 m.
It is formed in mm. Reference numeral 2 denotes an upper frame adhesively attached to the upper end of each transparent tempered glass 1 with adhesive resin 3, and the inner side exposed to the coat side and the inner surface of the transparent tempered glass 1 on the coat side are on the same plane. That's what I do. Reference numeral 2a denotes a mounting portion that stands integrally above the upper frame 2, and is adapted to abut from the inside of the court against a recessed portion _B1 formed at the lower end of the side wall B of the building. Reference numeral 2c denotes a large number of elongated holes extending vertically and arranged in parallel in the mounting portion 2c.

Reference numeral 4 denotes a long mounting bracket with an L-shaped cross section that is buried in the recessed portion _B1 , and its vertical portion is provided with a plurality of through holes 4a, and a plurality of through holes 4a are provided so as to correspond to each through hole 4a. Nut 5 is welded to. Reference numeral 6 denotes a large number of mounting bolts for fixing the upper frame 2 to the mounting bracket 4 and thereby suspending the transparent tempered glass 1 via the upper frame 2, each of which is connected to the elongated hole 2c of the upper frame 2. It passes through the through hole 4a of the mounting bracket 4 and is screwed into the nut 5. Reference numeral 7 denotes a bolt cover attached to the mounting portion 2a so as to cover the heads of the mounting bolts 6, and the inner side of the bolt cover is arranged so that the side wall B and the inner side of the upper frame 2 are on the same plane. . 8 is a silicon-filled resin filled between the bolt cover 7 and the side wall B and the upper frame 2, and its inner exposed surface is the same as the side wall B, the inside of the bolt cover 7, and the inside of the upper frame 2. It appears to be on a flat surface.

9 is an adhesive resin 3 attached to the lower end of the transparent tempered glass 1.
a lower frame adhesively attached by
The inside thereof and the inner surface of the transparent tempered glass 1 are made to be on the same plane, and a recess 9a is formed in the lower part. Reference numeral 10 denotes a fixed rail that is attached by anchor bolts 11 to a position corresponding to the lower frame 9 on the floor C of the building, and includes a long rail base 10a that abuts on the floor C and a fixed rail that is located above the rail base 10a. A part of the upper surface is formed with a plurality of rail members 10b formed as slopes (recesses). The fixed rail 10 has a rail member 10b fitted into the recess 9a of the lower frame 9, and a plurality of fixing bolts 12 screwed into the lower frame 9 from both the inside and outside of the court are brought into contact with the lower frame 9. This fixes the lower frame 9 so that it cannot move in the inward and outward directions. The weight of the transparent tempered glass 1 is not applied to the fixed rail 10.

To explain the construction method of this embodiment, first, when constructing the building itself, the mounting bracket 4 is buried in the position corresponding to the recessed part _B1 of the side wall B, and
As described above, the fixed rail 10 is fixed to the floor C at a position corresponding to the lower frame 9 with the anchor bolts 11. Further, an upper frame 2 and a lower frame 9 are adhesively attached to the upper and lower ends of the transparent tempered glass 1, respectively, using adhesive resin 3 to form both frames 2,
9 so that their inner sides are flush with the inner surface of the transparent tempered glass 1. This adhesion process is
Since it can be done in the factory instead of on-site, the gluing work can be done more easily and quickly than in the case of conventional racketball court wall structures, reducing construction time and ancillary work such as temporary construction costs and curing costs. It is possible to achieve significant cost reductions. Furthermore, since the adhesive resin 3 is made of a material that has a higher degree of curing and stronger adhesive force than the conventional silicone resin 23, there is less risk of the transparent tempered glass 1 peeling off from the frames 2 and 9 due to the impact force or the like. It is also possible to improve safety in use.

Next, as shown in FIG. 11, from inside the racketball court, while aligning the recess 9a of the lower frame 9 with the clearance of the upper surface of the rail member 10b,
The transparent tempered glass 1 is placed obliquely on a fixed rail 10 via the lower frame 9, and then raised to stand vertically on the fixed rail 10. Next, as shown in FIG. 12, the transparent tempered glass 1 is slightly lifted upward so that its weight does not fall on the rail stand 10a, and the mounting portion 2a of the upper frame 2 is placed in the recessed portion _B1 of the side wall B. Make it correspond. Next, when the mounting bolt 9 is passed through the elongated hole 2c and the through hole 4a and screwed onto the nut 5, the transparent tempered glass 1 is attached through the upper frame 2.
It is fixed to the side wall B in a suspended state. next,
By screwing the fixing bolt 12 into the lower frame 9 and bringing its tip into contact with the rail member 10b, the lower frame 9 is fixed to the fixed rail 10 so as not to be movable in the inward and outward directions. After that, the bolt cover 7 is attached to the attachment part 2a of the upper frame 2 so as to cover the heads of the plurality of attachment bolts 6, and then the silicon-filled resin 8 is inserted between the bolt cover 7, the side wall B, and the upper frame 2. The inner side is the same bolt cover 7, side wall B and upper frame 2.
It suffices to make it flush with the inside of the .

In this way, in this embodiment, at the construction site, the lower frame 9 and the upper frame 2 are simply attached to the fixed rails 10 and the mounting brackets 4 of the side wall B, respectively, which have been previously attached to the building, so the construction can be carried out easily and quickly. Therefore, it is possible to shorten the construction period and reduce costs such as construction costs. Furthermore, in this embodiment, since the transparent tempered glass 1 is suspended from the side wall B via the upper frame 2, there is no risk that the transparent tempered glass 1 will bend under its own weight.
Since the upper and lower glasses are not joined like in the wall structure using the hanging method shown in Figure 7, it is also possible to reduce the cost of materials by omitting the ribbed glass that was previously indispensable for this joining. can.

Next, another example of the first embodiment will be described with reference to FIG. 13. This example differs from the first embodiment in that the lower frame 9 is not used. That is, in this other example, the lower end of the transparent tempered glass 1 is adhesively attached using the adhesive resin 3 to a long fixture 15 attached to the floor C of the building.

To explain this alternative construction method, first, the mounting bracket 4 is buried in the side wall B of the building at a position corresponding to the recessed part B ₁ , and the mounting bracket 15 is buried in the position corresponding to the lower end of the transparent tempered glass 1 on the floor C. bury it. Further, an upper frame 2 is adhesively attached to the upper end of the transparent tempered glass 1 with an adhesive resin 3 so that the inside of the frame 2 is flush with the inner surface of the transparent tempered glass 1. This gluing process is the same as that of the first embodiment, and the gluing work can be performed more easily and quickly than in the conventional racket ball court wall structure, reducing construction time, temporary construction costs, and curing costs. It is possible to achieve significant cost reductions in incidental construction costs such as

Next, the lower end of the transparent tempered glass 1 is loosely inserted obliquely into the fixture 15 from inside the racket ball court, and then the transparent tempered glass 1 is stood vertically. Then, the transparent tempered glass 1 is fixed to the side wall B in a suspended state via the upper frame 2 in the same manner as in the first embodiment. Next, the lower end of the transparent tempered glass 1 is adhesively attached to the fixture 15 using the adhesive resin 3. Attachment of the bolt cover 7 and filling of the silicon filling resin 8 are performed in the same manner as in the first embodiment.

In this way, since the transparent tempered glass 1 is suspended from the side wall B via the upper frame 2 in this other example, no weight is applied to the lower end of the transparent tempered glass 1, so the adhesive resin 3 at the lower end of the transparent tempered glass 1 is suspended. The curing time required for the material to harden is reduced. Therefore, similar to the first embodiment, construction can be carried out easily and quickly, and therefore the construction period can be shortened and costs such as construction costs can be reduced.

In addition, even if the distance between the side wall B and the floor C of the building is uniform in the width direction of the transparent tempered glass 1 due to construction problems, etc., the distance between the lower end of the transparent tempered glass 1 and the fixture 15 should be uniform. Since this is permissible, there is no fear that the transparent tempered glass 1 will be impossible to attach.

Next, a second embodiment of the present invention will be described with reference to FIG. 14. This embodiment differs from the first embodiment in the attachment structure of the upper frame 2 to the side wall B. That is, in this embodiment, a recess 2b is formed above the upper frame 2. Reference numeral 13 denotes a hanging rail that is attached to the lower surface part B ₂ from below by mounting bolts 6 and adhesive just below the inner surface of the side wall B of the building, and includes a rail base 13a corresponding to the lower surface part B ₂ and a rail base 13a below it. It consists of a rail member 13b which is positioned and screwed to the rail base 13a. Same rail member 1
3b is a fixing bolt 1 that fits into the recess 2b of the upper frame 2 and is screwed into the upper frame 2.
By bringing the upper frame 2 into contact with the upper frame 2, the upper frame 2 is fixed so as not to be movable in the inner and outer directions. The transparent tempered glass 1 is suspended via the upper frame 2 by bonding the upper frame 2 to the rail stand 13a using silicone adhesive resin 3. Reference numeral 14 denotes a spacer inserted from the inside and outside into the gap created between the lower end of the lower frame 9 and the rail stand 10a of the fixed rail 10 when the transparent tempered glass 1 is suspended through the upper frame 2 as described above. , the inside of the court and the inside of the lower frame 9 and fixed rail 10 are made to be on the same plane. Further, the weight of the transparent tempered glass 1 is not applied to the spacer 14 itself.

Next, to explain the construction method of this second embodiment, first, when constructing the building itself, the mounting bracket 4 is buried in a position corresponding to the lower surface part _B2 of the side wall B, and as in the first embodiment, Fix the fixed rail 10 on C. Further, the process of bonding the upper frame 2 and lower frame 9 to the transparent tempered glass 1 is performed in the same manner as in the first embodiment. This allows for easier and faster gluing work than with conventional racketball court wall configurations, shortening the construction period and significantly reducing costs for incidental construction such as temporary construction costs and curing costs. can be achieved.

Further, a hanging rail 13 is attached to the upper frame 2 with fixing bolts 12 and adhesive resin 3.

Next, as in the first embodiment, the lower frame 9 is vertically placed on the fixed rail 10, and then the transparent tempered glass 1 to which both frames 2 and 9 are bonded is lifted upward, and the hanging rail 13 is placed on the side wall. Bottom part of B B ₂
If it is fixed from below with mounting bolts 6 and adhesive, the transparent tempered glass 1 is fixed to the side wall B in a suspended state via the upper frame 2. Next, by screwing the fixing bolt 12 into the lower frame 9 and pressing its tip onto the rail member 10b, the lower frame 9 is fixed to the fixed rail 10 so as not to be movable in the inward and outward directions. Thereafter, a spacer 14 may be interposed in the gap between the lower frame 9 and the rail stand 10a of the fixed rail 10 so that the inside thereof and the inside of the fixed rail 10 and the rail stand 10a are on the same plane.

Therefore, in this second embodiment as well, construction can be carried out easily and quickly in the same way as in the first embodiment, and the ribbed glass, which was indispensable in the past, can be omitted, thereby shortening the construction period and reducing material costs. It is possible to reduce costs such as construction costs, and it is also possible to improve safety during use.

In addition, in this second embodiment, by fixing the upper frame 2 to the ceiling A of the building so that the transparent tempered glass 1 is suspended through the upper frame 2, it is possible to use the racket ball court. It can also be used on the second floor of the four walls.

Next, a third embodiment of the present invention will be described with reference to FIG. 15. This embodiment differs from the second embodiment in the intervening position of the spacer 14. That is, the lower frame 9 is made to stand vertically on the fixed rail 10 as in the first and second embodiments, and then the transparent tempered glass 1 is placed so that the weight of the transparent tempered glass 1 reaches the fixed rail 1.
When the lower surface B ₂ of the wall surface B and the rail base 1 of the hanging rail 13 are lifted slightly to the extent that the
3a, a gap is created between the two. In this embodiment, a spacer 14 is interposed in this gap, and the spacer 14
The upper and lower surfaces of are bonded to the lower surface portion _B2 of the wall surface B and the rail stand 13a, respectively.

Therefore, in this third embodiment as well, construction can be carried out easily and quickly in the same way as in the first embodiment, and the ribbed glass, which has been indispensable in the past, can be omitted, thereby shortening the construction period and reducing material and labor costs. It is possible to reduce costs, etc., and improve safety during use.

Note that this third embodiment also has the same features as the second embodiment.
By attaching the upper frame 2 to the ceiling A of a building and supporting the transparent tempered glass 1 so as to suspend it, it can also be used on the second floor of the four walls of a racketball court.

Next, a fourth embodiment of the present invention will be described with reference to FIG. 16. This embodiment differs from the first embodiment in the position of the side wall to which the upper frame 2 is attached. That is, the lower surface of side wall B
A mounting member 24 having a through hole 24a is attached to B ₂ by being fixed to the mounting bracket 4 with a mounting bolt 6. The upper frame 2 is attached to the attachment member 24 with attachment bolts 6 and nuts 5, thereby fixing the transparent tempered glass 1 to the side wall B in a hanging state from below.

Next, to explain the construction method of this fourth embodiment, first, when constructing the building, the lower surface of the side wall B is
The mounting bracket 4 is buried in a position corresponding to B ₂ , and the mounting member 24 is fixed to the mounting bracket 4 with a mounting bolt 6 . Furthermore, a fixture 15 is buried in the floor C at a position corresponding to the lower end of the transparent tempered glass 1. The step of adhering the upper frame 2 to the upper end of the transparent tempered glass 1 is performed in the same manner as in each of the above embodiments. This allows for easier and faster gluing work than with conventional racketball court wall configurations, shortening the construction period and significantly reducing costs for incidental construction such as temporary construction costs and curing costs. can be achieved.

Next, similarly to the modification of the first embodiment, the lower end of the transparent tempered glass 1 is loosely inserted obliquely into the fixture 15 from inside the racket ball court, and then
The same transparent tempered glass 1 is made to stand vertically. Next, the transparent tempered glass 1 is slightly lifted upward to such an extent that its weight does not rest on the rail stand 10a, so that the mounting portion 2a of the upper frame 2 corresponds to the mounting member 24. Next, when the mounting bolt 6 is passed through the elongated hole 2c and the through hole 24a and screwed onto the nut 6, the transparent tempered glass 1 is attached to the side wall B from below through the upper frame 2 and the mounting member 24. Fixed in a suspended position. Next, the lower end of the transparent tempered glass 1 is adhesively attached to a fixture using adhesive resin 3. Attachment of the bolt cover 7 and filling of the silicone-filled resin 8 are performed in the same manner as in the first embodiment.

In this way, since the transparent tempered glass 1 is suspended from the side wall via the upper frame in this fourth embodiment as well, as described in the other example of the first embodiment,
The same effects as in each of the embodiments described above are achieved.

In this fourth embodiment as well, the upper frame 2 is attached to the ceiling A of the building to support the transparent tempered glass 1 in a suspended manner, and the shape of the fixture 15 is changed, so that the four wall surfaces of the racketball court can be fixed. It is also possible to use the second floor of the building.

In each of the above embodiments, transparent reinforced glass was used as the transparent plate material for the wall structure, but a transparent plate material such as transparent reinforced plastic may also be used instead.

Further, although the conventional ribbed glass is omitted in each of the above embodiments, the ribbed glass can be attached from the outside of the transparent tempered glass in order to further increase the strength.

Furthermore, the present invention can be applied not only to racketball courts, which are the object of each of the above embodiments, but also to courts for ball games such as squash courts.

Effects As described in detail above, the present invention has an upper frame 2 attached to the upper end of the transparent plate material 1 for wall structure provided vertically.
is fixed with adhesive resin 3 so that the inside of the upper frame 2 is flush with the inner surface of the transparent plate 1, and the upper frame 2 is attached to the ceiling A of the building.
Alternatively, the transparent plate 1 is fixed to the side wall B so as to be suspended via the upper frame 2, and the lower end of the transparent plate 1 is attached to the floor C of the building using a mounting mechanism so as to be movable in and out directions. As a result, construction can be carried out easily and quickly, thereby shortening the construction period and reducing costs such as material costs and construction costs. Moreover, it has an excellent effect of improving safety during use.
