It is provided with an extending coping 101, a crosspiece 102 horizontally mounted slightly above the skeleton S at the lower part of each support 1, and a panel 103 fitted in a space surrounded by the support 1, coping 101 and crosspiece 102. .

As shown in FIGS. 1 and 2, the column 1 is made of a hollow shape made of aluminum and extends vertically. However, as will be described later, the column 1 is held by the core material 2, the column 1 is not in contact with the skeleton S, and the lower end of the column 1 is located slightly above the upper surface of the skeleton S. The cross-sectional shape of the strut 1 is symmetrical in the front-rear and left-right directions, and is substantially rectangular with front and rear strut viewing surfaces 11 and left and right strut viewing surfaces 12. The front-rear length is approximately twice the left-right length. In addition, the column facing surface 11 is formed thicker than the column viewing surface 12. - 特許庁In addition, two tapping holes 13 are formed on the inner peripheral sides of the left and right post projection surfaces 12 so as to protrude toward the inner peripheral side. The tapping holes 13 are formed at a position approximately 30% rearward of the front end of the column 1 and approximately 30% forward of the rear end of the entire length.

The support 1 is held from the inside by a core material 2. - 特許庁That is, the core material 2 is inserted into the hollow part of the column 1, and the upper end of the core material 2 is located below the upper end of the column 1 (approximately 25% lower than the upper end of the column 1). position), and the lower end of the core member 2 protrudes below the lower end of the column 1 . Approximately the entire length of the portion of the core material 2 protruding from the column 1 is embedded in the skeleton S. As shown in FIGS. 1 and 2, the core member 2 is made of hollow aluminum and extends vertically. The cross-sectional shape of the core material 2 is symmetrical in the front-rear and left-right directions, and is a substantially rectangular shape having front and rear core material viewing surfaces 21 and left and right core material viewing surfaces 22 . However, the core material prospective surface 22 is composed of an enlarged portion 23 located in the center in the front-rear direction and an expected surface main portion 26 located in front and behind the enlarged portion 23 . The front view surface body portion 26 extends rearward from the end of the front core material viewing surface 21 , and the rear view surface body portion 26 extends toward the rear end of the core material viewing surface 21 . It extends from the front side. Further, the bulging portion 23 has a shape that bulges outward from the front and rear projection surface main portions 26, the details of which will be described later. The front and back length of the core material 2 is approximately three times the length between the left and right projection surface main body portions 26, and the core material projection surface 21 is formed thicker than the core projection surface 22. - 特許庁A concave portion 211 opening toward the inner peripheral side is formed in the center in the left-right direction of the inner peripheral surface of the core material facing surface 21 . The front and rear length of the core material 2 is slightly shorter than the front and rear length of the inner dimension of the column 1, and the left and right length of the core member 2 including the left and right enlarged portions 23 is the same as the inner dimension of the column 1. It is slightly shorter than the left and right length of the dimension.

The enlarged portion 23 is formed in a range of approximately 1/3 of the total length of the center of the left and right core material prospective surfaces 22 in the front-rear direction. . That is, the enlarged portion 23 is positioned at the center of the core member 2 in the front-rear direction, and is formed to face the left and right core member prospective surfaces 22 that are the two long sides of the core member 2 . More specifically, the cross-sectional shape is composed of a bottom side portion 231 parallel to the viewing surface main body portion 26 and positioned on the outer peripheral side of the viewing surface main body portion 26, and oblique side portions 232 formed on both front and rear sides of the bottom side portion 231. The oblique side portion 232 extends from the front end of the bottom side portion 231 toward the front and inner peripheral side to the rear end of the front side projection surface body portion 26, and the rear side oblique side portion 232 extends from the rear end of the bottom side portion 231 to the rear and It extends toward the inner peripheral side to the front end of the rear projection surface main body portion 26 and has a substantially trapezoidal shape with a bottom portion 231 and front and rear oblique portions 232 . A recessed portion 233 that opens toward the outer peripheral side is formed on the outer peripheral surface of the bottom portion 231 . Each oblique side portion 232 is inclined at approximately 45 degrees with respect to the projection surface main portion 26, and the four oblique side portions 232 in total of the two bulging portions 23 form part of a substantially square cross section. are arranged as In FIG. 2, a virtual square is indicated by a two-dot chain line, and each hypotenuse 232 is positioned on each side of this square. Projections 24 are formed on the inner sides of the left and right enlarged portions 23 that protrude toward the outer periphery. The projecting portion 24 forms a tapping hole and protrudes from the inner peripheral surface of the bottom portion 231 toward the inner peripheral side. The tip of the projecting portion 24 is flush with the inner peripheral surface of the projection surface body portion 26 , and the entire projecting portion 24 is housed inside the enlarged portion 23 .

The post 1 and the core member 2 configured in this manner are fixed by screws 6 . The screws 6 are attached at two upper and lower positions, and pass through a hole drilled in the front-back direction center of one of the supporting support surfaces 12 (the left side in FIG. 2) of the supporting support 1, The base portion 231 of the enlarged portion 23 and the projection portion 24 (tapping hole) are screwed together. The tip of the screw 6 is housed inside the enlarged portion 23 , that is, on the outer peripheral side of the inner peripheral surface of the projection surface main portion 26 . In addition, when the column 1 and the core member 2 are fixed, the swollen portion 23 of the core member 2 is accommodated between the tapping holes 13 on the front and rear sides of the column 1. 12 and the expected surface body portion 26 of the core material expected surface 22 .

Further, a plate-like reinforcing member 3 is inserted into the hollow portion inside the core member 2 . The reinforcing member 3 is made of steel and has a rectangular cross-sectional shape that is long in the front-rear direction. The length is slightly shorter than the inner dimension between the left and right prospective surface main body portions 26 . The vertical length is approximately half the length of the core material 2 . The protrusions 24 (tapping holes) of the core material 2 protrude from the inner peripheral surface of the core material 2 toward the outer peripheral surface of the opposed reinforcing material 3, but the protrusions 24 are housed inside the enlarged portion 23. Therefore, it does not interfere with the reinforcing member 3.

A seat plate 4 is attached to the lower end of the core member 2 . The seat plate 4 is made of stainless steel and has an octagonal plate shape when viewed from above. long. That is, the seat plate 4 is larger than the core member 2 in plan view. A sealing material 41 made of butyl tape is attached to the upper surface of the seat plate 4 . The sealing material 41 is large enough to cover the entire lower end surface of the core material 2 . A seat plate 4 is attached to the lower end of the core member 2 so as to sandwich a sealing material 41 between the lower end of the core member 2 and the seat plate 4 . It is screwed to the protrusion 24 (tapping hole). The seat plate 4 attached in this manner closes the opening at the lower end of the core member 2 , and the lower end of the reinforcing member 3 abuts the seat plate 4 via the seal member 41 .

The core material 2 and the reinforcing material 3 are integrated by the resin portion 5 . The resin portion 5 is made of hardened epoxy resin, and fills from the inner lower end of the core member 2 to a position higher than the upper end of the reinforcing member 3 . It fills the gap between the outer peripheral surfaces of the

Here, the procedure for constructing the core member 2, the reinforcing member 3, and the seat plate 4 will be described with reference to FIG. First, as shown in (a), the seat plate 4 is screwed to the lower end of the core member 2 , and the reinforcing member 3 is inserted from the upper end of the core member 2 . The reinforcing material 3 is positioned at the lower end of the core material 2 . Next, as shown in (b), liquid epoxy resin is filled from the opening at the upper end of the core material 2 . The epoxy resin penetrates into the gap between the core material 2 and the reinforcing material 3, but the opening at the lower end of the core material 2 is closed by the seat plate 4 (sealed by the sealing material 41). So the epoxy resin will not leak. The epoxy resin is filled up to a position higher than the upper end of the reinforcing material 3 . Then, as shown in (c), the epoxy resin is cured to form the resin portion 5, whereby the core member 2 and the reinforcing member 3 are integrated. After that, a through hole is formed as a drainage hole 25 in a portion of the core material expected surface 22 of the core material 2 above the resin portion 5 . The drain hole 25 is formed in the base portion 231 of the expanded portion 23 of one of the core material prospecting surfaces 22 . That is, the drain hole 25 is positioned at the center of the core material 2 in the front-rear direction. By forming the drainage hole 25 above the reinforcing member 3 in this manner, the reinforcing member 3 is prevented from coming into contact with water and corrosion of the reinforcing member 3 is prevented.

Next, a procedure for constructing the handrail 100 itself will be described with reference to FIGS. 1 and 5. FIG. The core member 2 to which the reinforcing member 3 and the seat plate 4 are attached as described above is fixed to the column 1 by screws 6, and the column 1, the coping 101, the crosspiece 102 and the panel 103 are assembled to form the handrail 100. . Further, as shown in FIG. 5( a ), pilot holes H are formed on the surface of the skeleton S at positions corresponding to the support columns 1 . The prepared hole H has a rectangular cross section and is larger than the seat plate 4 . Next, as shown in FIG. 5(b), the core material 2 at the lower end of each post 1 of the handrail 100 is inserted into each prepared hole H. Then, as shown in FIG. At this time, a spacer 200 is sandwiched between the surface of the skeleton S and the crosspiece 102, and as shown in FIGS. is located above the bottom surface of the pilot hole H. Then, the pilot hole H is filled with a grout material G made of non-shrink mortar or epoxy resin and cured. In this way, the lower end portion of the core member 2 and the seat plate 4 are embedded in the skeleton S, and the handrail 100 is erected.

According to the handrail of the present invention constructed in this manner, the seat plate 4 is attached to the lower end of the hollow core member 2 and the opening is closed, so that the reinforcement inserted into the core member 2 can be removed. The lower end of the material 3 abuts on the seat plate 4 and is easily and reliably positioned. In addition, when forming the resin part 5, by pouring the epoxy resin from the opening at the upper end of the core material 2, the leakage of the epoxy resin is prevented by the seat plate 4, and the core material 2 is filled with the epoxy resin. The core material 2 and the reinforcing material 3 are integrated into the resin part 5 by being hardened and hardened. In this way, since the reinforcing member 3 is inserted under the core member 2, the legs of the core member 2 where the maximum bending moment is generated when a horizontal force is applied to the handrail are efficiently and reliably reinforced. be. Further, since the seat plate 4 is larger than the core material 2, when the lower end portion of the core material 2 and the seat plate 4 are embedded in the frame S, the seat plate 4 is caught to prevent the frame from floating up. The core material 2 is securely fixed to the S. Further, since the post 1 and the core member 2 are fixed by the screws 6, and the screws 6 penetrate through the post projection surface 12 of the post 1 and are screwed into the core member 2, when a load is applied in the projection direction, There are no holes in the column facing surface 11 or the core facing surface 21 where the stress is maximum. Normally, a load acts on the handrail in the expected direction, such as when a person leans on it, so such a structure substantially increases the strength of the handrail. In addition, the core material 2 has an enlarged portion 23 that bulges toward the outer peripheral side in its cross-sectional shape, the screw 6 is screwed into the enlarged portion 23, and the tip of the screw 6 that is screwed into the core material 2 is inside the enlarged portion. Therefore, the screw 6 does not interfere with the reinforcing member 3, and the cross-sectional area of the plate-shaped reinforcing member 3 is set to the inner dimension of the main body portion 26 of the core material viewing surface 21 and the core material viewing surface 22. It is made as large as possible and has a higher strength.

Moreover, the core member 2 has projections 24 that protrude from the inner peripheral surface toward the outer peripheral surface of the opposing reinforcing member 3 . As a result, the contact area of the core material 2 with the resin portion 5 is increased, so that the core material 2 and the reinforcing material 3 are more strongly integrated.

Further, the post 1 has a substantially rectangular cross-sectional shape that is long in the viewing direction, and the core member 2 has a substantially rectangular cross-sectional shape that is long in the viewing direction. As a result, the load acts on the handrail in the expected direction, so the handrail has a higher strength against the load.

In addition, the enlarged portion 23 is formed to face both of the two long sides of the core material 2 (core prospective surface 22), and the cross-sectional shape thereof is a bottom side portion 231 parallel to the long sides of the core material 2. and oblique side portions 232 formed on both sides of the base portion 231 in the prospective direction. are arranged so as to form As a result, the strength against torsion around the longitudinal axis of the core material 2 is increased.

Further, the enlarged portion 23 is positioned at the center of the core material 2 in the front-rear direction (projection direction). As a result, the screw holes for the screws 6 that fix the support 1 and the core 2 are formed on the neutral axis (position where no stress is generated) when a load acts in the prospective direction, so the strength is higher. becomes.

The protrusion 24 forms a tapping hole, and the seat plate 4 is attached to the core member 2 by screwing into the tapping hole. This makes the mounting work of the seat plate 4 very easy.

In addition, the drain hole 25 is positioned at the center of the pillar projection surface 12 in the front-rear direction (projection direction). As a result, there is no hole in the support support surface 11 where the stress is maximized when the load acts in the direction of projection, and the drain hole 25 is the neutral axis ( Since it is formed on a position where stress does not occur), the strength is higher.

Next, another embodiment of this handrail will be described. Another embodiment shown here differs from the previous embodiment in the cross-sectional shape of the core material 2, and only the core material 2 will be described here. As shown in FIG. 6, the core material 2 of another embodiment has a core material viewing surface 21 and a core material viewing surface 22 (a viewing surface main body portion 26 and an enlarged portion 23) in the same manner as the core material 2 of the previous embodiment. ), and the shape of the outer peripheral surface is the same. The inside of the bulging portion 23 is solid, and the inner peripheral surface of the bulging portion 23 and the inner peripheral surfaces of the front and rear projection surface body portions 26 are flush with each other. It is made thicker than A wavy protruding portion 24 is formed over the entire inner peripheral surface of the enlarged portion 23 and the projection surface main portion 26 . The projecting portion 24 is formed by arranging a plurality of projections of the same shape in the front-rear direction, and the height of the projections is lower than the thickness of the viewing surface main body portion 26 .

Also in another embodiment configured in this manner, the contact area of the core material 2 with the resin part 5 is increased by the wavy protrusions 24 , so that the core material 2 and the reinforcing material 3 are more firmly integrated.

Further, the core member 2 having the outer shape as in the above-described embodiment corresponds to the strut 1 having a different shape of the inner peripheral surface. That is, the core member 2 has an enlarged portion 23 formed in the center in the front-rear direction, and a gap is formed between the projection surface main body portion 26 and the post projection surface 12 in the front and rear of the enlarged portion 23 . The inner peripheral surface of the strut 1 may be of any shape as long as it fits in the gap. As an example, as shown in FIGS. 7A and 7B, there is a case where the tapping holes 13 formed on the inner peripheral surface of the supporting support surface 12 are different in position. In the case of FIG. The hole 13 is formed at a position distant from the central enlarged portion 23, and in the case of FIG. 7B, the tapping hole 13 is formed at a position close to the central enlarged portion 23. FIG. In addition, in the case of FIG. 7(a), a substantially L-shaped bracket 7a is screwed and fixed to the supporting support surface 11. As shown in FIG. In the case of FIG. 7B, brackets 7b sandwiching the support 1 from the left and right are screwed and fixed to the support support surface 12 from the left and right at the positions of the tapping holes 13. As shown in FIG.

Furthermore, when the column 1 and the core member 2 are fixed by the screw 6, it is desirable to pass the screw 6 through and screw into the projection surface of the column 1 and the core member 2 as described above. Alternatively, the screw 6 may be passed through and screwed into the viewing surfaces of the support 1 and the core member 2 . Such a case includes, for example, the case of attaching metal fittings 8a for attaching furring strips to the pillar expected surface 12 as shown in FIG. 12 to which the vertical frame 8b is attached. In the case of FIG. 8(a), the screws 81a for attaching the metal fittings 8a are positioned on the front and rear sides of the bulging portion 23 of the core material 2, and the tips of the screws 81a are projected onto the pillar projected surface 12. Positioning between the surface body portions 26 prevents the screw 81 a from interfering with the core member 2 . In the case of FIG. 8(b), the screw 81b for attaching the vertical frame 8b is positioned at the same front and back position as the bulging portion 23 of the core material 2, but the tip of the screw 81b 233 prevents the screw 81b from interfering with the core member 2. As shown in FIG.

The present invention is not limited to the above-described embodiments, and the shape and structure of each part can be changed as appropriate within the scope of the invention, taking into consideration the situation of the installation location, the design, and the like.
