Summary of the Invention

Problems to be Solved by the Invention

[0004] In the handrail fence shown in FIG. 12 (Patent Document 1), in the assembled (completed) state, the auxiliary frame 53 was conspicuous from the outdoor side at the joint position of the glass plates 51 and 51, which impaired the aesthetic sense.

[0005]

[0006] Therefore, as shown in FIG. 13, an auxiliary frame 54 is fixed to the outdoor surface of the main pillar 52, and the glass plates 51, 51 are adhered to the outer surface of the auxiliary frame 54 via a sealing agent 56 in a state where the joints 60 of the glass plates 51 and 51 are brought closer to each other. However, in the structure of FIG. 13, there remain the following problems: (i) Since it is a so-called wet method, it takes several days for the sealing agent 56 to solidify; (ii) Skilled labor and time are required to apply the sealing agent on-site, making on-site construction troublesome and inefficient; and (iii) The cost is high.

[0007] Therefore, an object of the present invention is to solve such problems, enable efficient construction in a short time by a so-called dry method, reduce costs, and set the joint between glass plates to a sufficiently small gap dimension when viewed from the outside. When viewed from the outside, the glass surfaces are continuously in the same vertical plane, providing a handrail fence with excellent appearance.

Means for Solving the Problems

[0008] Therefore, the present invention includes a plurality of columns erected at a predetermined interval; and a panel structure body that is inserted and attached from above to below to the outdoor side end surfaces of adjacent columns via a male-female insertion mechanism. The panel structure body has a glass plate and a metal upper frame and lower frame fixed to the upper and lower sides of the glass plate. The left and right sides of the glass plate directly face each other with a small gap dimension. Further, the metal upper frame and the upper end of the column are covered with a metal upper capping piece.

[0009] Also, the small gap dimension is set to 8 mm or less. The upper frame has a downward-opening recess. The upper side of the glass plate is inserted into the outdoor end of the recess, and two wedge members having gradient surfaces that are slidably in contact with each other are fitted into the recess. The wedge member on the indoor side of the recess is moved upward by a screw that screws in from above, and the wedge member on the outdoor side presses the upper side of the glass plate by sliding contact with the gradient surface. The upper side of the glass plate is fixed to the metal upper frame by being clamped between the inner surface on the outdoor side of the recess and the wedge member on the outdoor side.

[0010] In addition, the lower frame has an upwardly open recess. At the outdoor end of the recess, the lower edge of the glass plate is inserted, and two wedge members having gradient surfaces that are slidably in contact with each other are fitted into the recess. The wedge member on the indoor side of the recess is moved downward by a screw that is screwed in from below, and the outdoor side wedge member presses the lower edge of the glass plate by sliding contact with the gradient surface. The lower edge of the glass plate is fixed to the metal lower frame by being clamped between the inner surface on the outdoor side of the recess and the outdoor side wedge member.

[0011] In addition, double-sided tapes are adhered to the inner and outer surfaces of the upper edge of the glass plate to be clamped. In addition, double-sided tapes are adhered to the inner and outer surfaces of the lower edge of the glass plate to be clamped. In addition, the cross-sectional shape of the upper wall portion of the metal upper cill is a triangular peak shape having a peak at a position above the upper frame of the panel structure and gently sloping downward in the outdoor direction and the indoor direction.

Advantages of the Invention

[0012] According to the present invention, on-site work can be efficiently carried out in a short time (by a dry construction method) without using an adhesive or the like that requires a long drying time (hours). When viewed from the outside, no auxiliary frame can be seen at the position of the joint between the glass plates, and it is possible to obtain a handrail fence with an excellent appearance as a vertically continuous glass surface with a sufficiently small gap on the left and right.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, the present invention will be described in detail based on the illustrated embodiments. As shown in FIG. 6, a plurality of support columns 1 erected on a weir wall (body) 11 at a predetermined interval are provided, and panel structures P are sequentially attached between adjacent support columns 1.

[0015] As shown in FIG. 9, the support column 1 is composed of a steel inner column 2 having high strength and an outer column 3 made of extruded aluminum and having a substantially rectangular cylindrical cross-sectional shape (excellent in external design). Then, the outer column 3 is connected and fixed to the inner column 2 with a fixing tool such as a bolt 25 (see FIGS. 1 and 2).

[0016] Also, as shown in FIGS. 9 to 11, ant grooves 4, 4 are formed on one short side 3A of the substantially rectangular cylindrical cross-sectional shape of the outer column 3. The one short side 3A on which these ant grooves 4, 4 are formed is erected on the weir wall 11 at a predetermined interval so as to be the outdoor side end face 5 as shown in FIG. 6.

[0017] In FIGS. 6, 8, and FIGS. 10, 11, the arrow N0 indicates the outdoor direction. On the left and right end faces 6, 6 of the panel structure P, there are fixed attachment members 7 each having a T-shaped male portion 8 that protrudes indoors in the direction N1 and is inserted into the dovetail groove 4 of the support column 1 from above.

[0018] That is, via the male-female insertion mechanism Z composed of the dovetail groove 4 and the T-shaped male portion 8, the panel structure P is attached to the outdoor end faces 5 of the adjacent support columns 1, 1. And as shown in FIGS. 1 to 5, the panel structure P has a glass plate 10 and metal upper and lower frames 12 and 13 fixed to the upper side 10A and the lower side 10B of the glass plate 10.

[0019] And as shown in FIGS. 1, 2, and 8, the metal upper coping 20 covers the metal upper frame 12 and the upper end 1A of the support column 1.

[0020] Also, as shown in FIGS. 7 and 11, the left side 10L and the right side 10R of the adjacent glass plates 10, 10 face each other directly with a small gap dimension W 10 That is, a part of the support column 1, an auxiliary vertical frame, and "other members" such as packing do not intervene between the left and right side edges 10L, 10R of the glass plate 10 and face each other directly.

[0021] The small gap dimension W 10 is set to 8 mm or less. Desirably, 3 mm ≤ W 10 ≤ 7 mm. More desirably, 4 mm ≤ W 10 ≤ 6 mm. If it is less than the lower limit value, it becomes difficult to attach the attachment member 7 (see FIG. 11). Conversely, if it exceeds the upper limit value, the continuous planar aesthetic feeling (appearance) of the glass plate 10... as seen from the outside decreases.

[0022] And in FIGS. 1 to 5, the method and configuration (structure) for fixing the upper and lower frames 12 and 13 to the upper side 10A and the lower side 10B of the glass plate 10 will be described. First, a configuration in which the upper frame 12 is attached to the upper side 10A of the glass plate 10 will be described. The upper frame 12 is made of an extruded profile having a downward-opening recess 14. Specifically, the upper frame 12 forms the downward-opening recess 14 with a ceiling wall portion 12A, an outdoor hanging piece 12B, and a cornered J-shaped indoor hanging piece 12C. Further, the ceiling wall portion 12A has an expanded wall portion 12E that forms a horizontally inverted U-shaped hollow hole 12D on its upper surface.

[0023] The upper side 10A of the glass plate 10 is inserted in a state approaching the hanging piece 12B on the outdoor end side of the recess 14 of the upper frame 12. Double-sided tapes 18 are adhered to both the inner and outer surfaces of the upper side 10A of the glass plate 10 in advance.

[0024] And two wedge members 16, 17 having gradient surfaces X that are slidably in contact with each other 16 , X 17 are fitted into the recess 14 shown in FIGS. 5 to 4. Specifically, as shown in FIG. 5, the outdoor wedge member 16 is first fitted into the recess 14. Next, the indoor wedge member 17 is pulled upward, as indicated by arrow Y (see FIG. 5), by a tapping screw 19 that penetrates the hollow hole 12D from above (screws in from above).

[0025] The gradient surface X of the indoor wedge member 17 17 abuts against the gradient surface X of the outdoor wedge member 16 16 to move this wedge member 16 in the outdoor direction and press the upper side 10A of the glass plate 10. The upper side 10A of the glass plate 10 is clamped (held) between the inner surface 14A on the outdoor side of the recess 14 ── that is, the inner surface of the hanging piece 12B ── and the outdoor wedge member 16. By being clamped (held) in this way, the upper side 10A of the glass plate 10 is fixed to the metal upper frame 12.

[0026] In this clamped state, the hanging piece 12B of metal and the metal wedge member 16 prevent the upper edge 10A of the glass plate 10 from being locally and intensively pressed against and damaged, and the double-sided tapes 18, 18 (described above) serve to prevent this, and also serve to ensure that they are firmly adhered to each other. By the way, in FIGS. 4 and 5, the wedge member 17 integrally has an L-shaped extending piece portion 17A in the indoor direction, wraps the above-described hanging piece 12C, and always maintains a stable posture.

[0027] Next, a configuration for attaching the lower frame 13 to the lower edge 10B of the glass plate 10 will be described. The lower frame 13 is made of an extruded profile having an upwardly open recess 15. Specifically, the lower frame 13 forms the above-described upwardly open recess 15 by a bottom wall portion 13A, an outdoor standing piece 13B, and an angularly inverted J-shaped indoor standing piece 13C. Further, the bottom wall portion 13A has an inflated wall portion 13E that forms a horizontally inverted U-shaped hollow hole 13D on its upper surface. The lower edge 10B of the glass plate 10 is inserted in an approaching state into the standing piece 13B on the outdoor end side of the recess 15 of the lower frame 13. Double-sided tapes 18 are attached in advance to the inner and outer surfaces of the lower edge 10B of the glass plate 10.

[0028] And a gradient surface X 16 , X 17 having two wedge members 16, 17 are inserted into the recess 15 shown in FIGS. 5 to 4. Specifically, as shown in the lower half of FIG. 5, the outdoor wedge member 16 is first inserted into the recess 15. Next, the indoor wedge member 17 is pulled downward as indicated by the arrow Y' (see FIG. 5) by a tapping screw 19 that penetrates the hollow hole 13D from below (screws in from above).

[0029] The gradient surface X 17 of the indoor wedge member 17 16 abuts against the gradient surface X of the outdoor wedge member 16, and moves this wedge member 16 in the outdoor direction to press the lower edge 10B of the glass plate 10. The lower edge 10B of the glass plate 10 is clamped (held) by the inner surface 15A on the outdoor side of the recess 15 ─── that is, the inner surface of the upright piece 13B ─── and the outdoor wedge member 16. By being clamped (held) in this way, the lower edge 10B of the glass plate 10 is fixed to the metal lower frame 13.

[0030] In this clamped state, the metal upright piece 13B and the metal wedge member 16 are prevented from locally and intensively pressing against the lower edge 10B of the glass plate 10 and causing damage or breakage by the double-sided tapes 18, 18 (described above), and also serve to securely adhere to each other.

[0031] By the way, in FIGS. 4 and 5, the lower wedge member 17 integrally has an inverted L-shaped extension piece 17B extending in the indoor direction, encloses the above-described upright piece 13C, and always maintains a stable posture.

[0032] In this way, as shown in FIGS. 5 to 4, the upper frame 12 and the lower frame 13 are attached to the upper edge 10A and the lower edge 10B of the glass plate 10. Moreover, by screwing in the (tapping) screw 19, the gradient surface X of the wedge member 16 16 and the gradient surface X of the wedge member 17 17 are slidably contacted and tightened, enabling the work to be carried out quickly and easily. However, in FIGS. 5 and 4, the actual work may be carried out with the top and bottom reversed or in a 90° lying-down state (horizontal plane state).

[0033] For the four sides of the glass plate 10, the upper frame 12 and the lower frame 13 are attached to the upper edge 10A and the lower edge 10B as shown in FIGS. 5 and 4, but no such metal frame members are attached to the left and right sides. Simply, a thin attachment member 7 is merely attached to such an extent that it is not noticeable (see FIG. 11).

[0034] Next, referring back to FIGS. 1, 2, and 3. 21 is a lower capping piece, which is attached to cover the upper surface of the weir wall 11. A reinforcing pipe body 22 is inserted into the hollow part closer to the indoor side of the upper capping piece 20 and fixed to the upper end of the outer column 3 by a screw 23 from below.

[0035] Incidentally, as shown in FIG. 2, the upper wall portion 20A of the metal upper coping 20 has a cross-sectional shape of a triangular mountain shape with a low vertical height. Moreover, the apex 20P of the triangular mountain shape is correspondingly located above the upper frame 12 of the panel structure P.

[0036] In other words, the apex 20P exists outside the house side rather than at half (1 / 2·W) of the thickness dimension W shown in FIGS. 1 and 2. Thus, the upper wall portion 20A of the upper coping 20 has a triangular mountain shape that gently slopes downward in the outdoor direction N0 and the indoor direction N1. At the outer end of this upper wall portion 20A, there is also a hanging wall portion 20B with a small vertical dimension H B continuously provided.

[0037] Incidentally, the two-dot chain line L 20 shows the shape of the upper wall portion of the upper coping that has been generally used in the past. That is, in the conventional upper coping, as shown by the two-dot chain line, the vertical dimension H of the outdoor end face F is large, and it can be seen that in the past, when viewed from outside the house, the upper coping was conspicuous.

[0038] In contrast, in the present invention, the vertical dimension H of the hanging wall portion 20B B is smaller than the conventional vertical dimension H F by 30% to 60%. When looking up from outside the house, the presence of the upper coping 20 is eliminated (not conspicuous), and it is possible to give a neat aesthetic feeling.

[0039] In particular, the gradient portion 20Z that slopes downward from the apex 20P in the outdoor direction N0 is not visible when a person looks up from below outside the house. Therefore, the upper coping 20 gives a neater feeling (appears thinner).

[0040] Note that the "glass plate" in the present invention may be any of transparent, translucent, and opaque, and is not limited to a single glass sheet, and may be laminated glass as well.

[0041] As described in detail above, the present invention includes a plurality of columns 1 erected at a predetermined interval; and a panel structure P that is inserted and attached from above to below to the outdoor side end faces 5 of the adjacent columns 1, 1 via a male-female insertion mechanism Z. The panel structure P has a glass plate 10 and metal upper and lower frames 12 and 13 fixed to the upper side 10A and lower side 10B of the glass plate 10. The left side 10L and right side 10R of the glass plate 10 face each other directly with a small gap dimension W 10 Since the metal upper frame 12 and the upper end 1A of the column 1 are covered with a metal upper coping 20, it can be efficiently carried out in a short time. That is, a so-called dry construction method is sufficient, and troublesome and skilled operations such as the application and drying of a sealing agent as described in FIG. 13 of the prior art can be omitted. In particular, when viewed from the outside, an auxiliary (column) frame attached from the outside (see reference numeral 53 in FIG. 12) can be omitted at the joint of the glass plates, and the glass plates 10 and 10 can be made into a handrail fence with excellent appearance as a continuous vertical plane. In other words, all of the columns 1... are present on the indoor side surface of the glass plate 10 and are completely hidden and inconspicuous from the outside.

[0042] In the present invention, since the small gap dimension W 10 is set to 8 mm or less, the column 1 is not visible at all from the gap between the left and right side edges 10L and 10R of the adjacent glass plates 10 and 10 (when viewed from the outside), and the glass plate 10 appears as a continuous vertical plane, exhibiting excellent aesthetic feeling.

[0043] The upper frame 12 has a downward-opening recess 14. At the outdoor end of the recess 14, the upper side 10A of the glass plate 10 is inserted, and two wedge members 16 and 17 having gradient surfaces X 16 , X 17 that are in slidable contact with each other are fitted into the recess 14. The wedge member 17 on the indoor side of the recess 14 moves upward by a screw 19 screwed in from above, and the wedge member 16 on the outdoor side is on the gradient surface X 16 , X 17By the butt joint, the upper side 10A of the glass plate 10 is pressed; the inner surface 14A on the outdoor side of the recess 14 and the wedge member 16 on the outdoor side clamp the upper side 10A of the glass plate 10, so that the upper side 10A of the glass plate 10 is fixed to the metal upper frame 12. Therefore, the glass plate 10 and the upper frame 12 can be easily, quickly and efficiently assembled.

[0044] Further, the lower frame 13 has a recess 15 with an upward opening. At the outdoor end of the recess 15, the lower side 10B of the glass plate 10 is inserted, and a gradient surface X that is in slidable contact with each other 16 ,X 17 Two wedge members 16 and 17 having are fitted into the recess 15; the wedge member 17 on the indoor side of the recess 15 moves downward by a screw 19 screwed in from below, and the wedge member 16 on the outdoor side is on the gradient surface X 16 ,X 17 By the butt joint, the lower side 10B of the glass plate 10 is pressed; the inner surface 15A on the outdoor side of the recess 15 and the wedge member 16 on the outdoor side clamp the lower side 10B of the glass plate 10, so that the lower side 10B of the glass plate 10 is fixed to the metal lower frame 13. Therefore, the glass plate 10 and the lower frame 13 can be easily, quickly and efficiently assembled.

[0045] In addition, double-sided tapes 18 are adhered to the inner and outer surfaces of the upper side 10A of the glass plate 10 to be clamped. Therefore, the upper side 10A of the glass plate 10 is clamped between the inner surface 14A on the outdoor side and the wedge member 16 through the double-sided tape 18 as an appropriate "buffer material", so that minute unevenness between the pressure contact surfaces can be absorbed and the impact resistance is excellent.

[0046] In addition, double-sided tapes 18 are adhered to the inner and outer surfaces of the lower side 10B of the glass plate 10 to be clamped. Therefore, the lower side 10B of the glass plate 10 is clamped between the inner surface 15A on the outdoor side and the wedge member 16 through the double-sided tape 18 as an appropriate "buffer material", so that minute unevenness between the pressure contact surfaces can be absorbed and the impact resistance is excellent.

[0047] Further, the cross-sectional shape of the upper wall portion 20A of the metal upper coping 20 is a triangular mountain shape having a vertex 20P and gently sloping downward in the outdoor direction N0 and the indoor direction N1 at a position above the upper frame 12 of the panel structure P. Therefore, when a person looks up from the outside, the vertical width dimension of the upper coping 20 appears small, and the upper coping 20 becomes hardly noticeable, giving a neat aesthetic feeling.
