In the joint portion 3A, a joint portion arranging part 30 (30A) extended along the end surface 25 of the cap tree 2 cut at 45 ° with respect to the longitudinal direction of the cap tree 2 is arranged, and in the joint portion 3B, the cap tree is arranged. A joint portion arranging component 30 (30B) extending along an end surface 25 of the Kasagi 2 provided in a direction orthogonal to the longitudinal direction of the 2 is arranged.
As shown in FIGS. This will be described as the joint portion arranging component 30.

As shown in FIG. 5, the joint portion arranging component 30 includes a central skeleton installation portion 31, an end skeleton installation portion 33, and a fin portion 35. The central skeleton installation portion 31 and the end skeleton installation portion 33 are made of a semi-hard resin or a hard resin, for example, semi-hard ethylene propylene rubber (EPDM), and the fin portion 35 is made of a soft resin, for example, soft ethylene propylene. It is composed of rubber (EPDM). Therefore, the central skeleton installation portion 31 and the end skeleton installation portion 33 are solid portions, and the fin portion 35 is a sponge portion. The materials of the semi-hard resin, the hard resin, and the soft resin are not limited to EPDM, and may be selected according to the performance and cost required for the joint portion arranging component 30.

The central skeleton installation portion 31 includes a drainage passage portion 310 and a connecting piece portion 320. The drainage passage portion 310 is formed in a gutter shape by a bottom portion 311 and a pair of side wall portions 312, and is provided along the end surface 25 of the cap tree 2 of the joint portions 3A and 3B. In the present embodiment, convex portions 313 continuous in the longitudinal direction of the joint portion arranging component 30 are formed in the width direction of the bottom portion 311, that is, in the left and right central portions in the direction orthogonal to the longitudinal direction of the joint portion arranging component 30. Has been done. As a result, in the drainage passage portion 310, two drainage grooves 314 continuous in the longitudinal direction of the joint portion arranging component 30 are formed by the bottom portion 311 and the convex portion 313 and the left and right side wall portions 312. There is.

The width dimension of the drainage ditch 314 is, for example, 2.5 mm, which is a shape that promotes the capillary phenomenon. As a result, the rainwater that has entered the drainage ditch 314 does not stay in the drainage ditch 314 and is smoothly drained from the end opening in the longitudinal direction of the joint portion arranging component 30.
In the joint portion arranging component 30 of the present embodiment, the width dimension of the convex portion 313 is 2.5 mm, and the width dimension of the side wall portion 312 is 2.5 mm. Therefore, the width dimension of the drainage passage portion 310, that is, the width dimension between the outer surfaces of the side wall portions 312 is 12.5 mm.

A step 315 is formed at the upper end of the side wall portion 312. The step 315 is formed on the inner surface of the side wall portion 312, that is, on the inner surface continuous with the drainage groove 314. In the present embodiment, the bottom surface of the step 315 is located at a height of 3 mm from the bottom surface of the drainage groove 314, and is provided at the same height level as the top surface of the convex portion 313. Further, the width dimension between the side surfaces of the step 315 is set to 10 mm.
Therefore, as shown in FIG. 5, when the end face 25 of the cap tree 2 is aligned with the side surface of the step 315, a gap of 10 mm is set between the end faces 25 of the cap tree 2 in the joint portions 3A and 3B.

The connecting piece portion 320 extends outward from the upper end of the side wall portion 312. The upper surface of the connecting piece 320 is inclined so as to be lowered toward the drainage ditch 314. As a result, the rainwater that has fallen on the upper surface of the connecting piece 320 can be smoothly flowed into the drainage ditch 314.

The end skeleton installation portion 33 includes an extension portion 330 extending downward from the tip end portion of the connecting piece portion 320, and a fixing piece portion 340 protruding outward from the lower end portion of the extension portion 330.
A groove 331 is formed on the surface of the extension portion 330 in the direction along the end surface 25 of the cap tree 2 of the joint portions 3A and 3B, that is, in the longitudinal direction of the joint portion arranging component 30. The groove 331 is formed in the upper end portion of the extension portion 330, that is, the connecting portion with the connecting piece portion 320. Therefore, when the groove 331 is cut out with a cutter or the like, the end skeleton installation portion 33 can be separated from the central skeleton installation portion 31 as shown in FIG.
Further, since the extension portion 330 is formed continuously from the tip end portion of the connecting piece portion 320 and is provided at a position away from the side wall portion 312, a groove portion 332 is formed between the extension portion 330 and the side wall portion 312. There is. The width dimension of the groove portion 332 is, for example, 3.25 mm, and the width dimension between the inner surfaces of the extension portion 330 is, for example, 20 mm.
Therefore, when the end skeleton installation portion 33 is separated from the central skeleton installation portion 31, the base plate 51 can be inserted into the groove portion 332 as shown in FIG. Therefore, the minimum distance between the base plates 51 can be reduced to a dimension close to the width dimension of the drainage passage portion 310, the distance between the columns 52 can also be reduced, and the distance can be set to prevent children from slipping through.

As shown in FIG. 5, the lower surface of the fixed piece portion 340 has the same height level as the lower surface of the bottom portion 311. Therefore, when the joint portion arranging component 30 is installed on the upper surface of the skeleton 1, the bottom surface portion 311, that is, the lower surface of the central skeleton installation portion 31, and the fixed piece portion 340, that is, the lower surface of the end skeleton installation portion 33 are formed on the skeleton 1. It is configured to be in contact with the upper surface.
The upper surface of the fixed piece portion 340 is inclined so as to be lowered toward the outside, that is, toward the tip end side. Therefore, when the joint portion arranging component 30 is installed on the skeleton 1, the step between the tip of the fixed piece portion 340 and the upper surface of the skeleton 1 can be reduced.
A single-sided tape 40 having an adhesive layer on one side is attached from the upper surface of the skeleton 1 to the upper surface of the fixed piece portion 340 and the side surface of the extension portion 330, and the single-sided tape 40 allows the joint portion arranging component 30 to be attached to the skeleton. It is fixed at 1.

The fin portion 35 is formed in a fin shape and stands upright from the upper surface on the tip end side of the connecting piece portion 320. The fin portion 35 is formed so as to be curved outward from the base end portion 351 continuous to the upper surface of the connecting piece portion 320 toward the upper tip portion 352. Therefore, the fin portion 35 is continuously provided from the side wall portion 312 of the drainage passage portion 310 via the connecting piece portion 320.
In the fin portion 35, the surface 353 in contact with the cap tree 2 is coated with a synthetic resin and subjected to a sliding treatment. The surface 353 is a surface that comes into contact with the cap tree 2 when the cap tree 2 is pressed from above. Sliding treatment is applied. Since the surface 353 of the fin portion 35 is slidable, the frictional resistance between the fin portion 35 and the cap tree 2 can be reduced when the cap tree 2 is fitted into the holder 6, and the cap tree 2 can be held in the holder 6. Can be easily fitted into. The synthetic resin used for the sliding treatment may be any as long as it can reduce the frictional resistance of the fin portion 35, and for example, a silicone resin, a fluororesin, or the like can be used.
Further, the tip portion 352 is formed in a substantially arcuate cross section, and it is possible to prevent the tip portion 352 from being caught when in contact with the cap tree 2 and increasing the frictional resistance.

Next, the construction procedure of the Kasagi of the present embodiment will be described.
The operator marks a positioning line or the like on the upper surface of the skeleton 1 on which the holder 6, the joint portion arranging component 30, and the base plate 51 are arranged.
Next, the holder 6, the joint portion arranging component 30, and the base plate 51 are fixed to the upper surface of the skeleton 1 in accordance with the marked positions on the upper surface of the skeleton 1. That is, the holder 6 and the base plate 51 are screwed to the skeleton 1.
On the other hand, among the joint portion arranging parts 30, the joint portion arranging component 30A arranged in the joint portion 3A cuts the end skeleton installation portion 33 portion that interferes with the base plate 51 from the groove portion 332, as shown in FIG. Keep it.
Next, the joint portion arranging component 30 is installed on the upper surface of the skeleton 1 so that the convex portion 313 located at the center in the width direction is aligned with the line marked on the upper surface of the skeleton 1, and the one end skeleton installation portion 33 is installed. A single-sided tape 40 is attached over the upper surface of the skeleton 1 and temporarily fixed. After the temporary fixing, the marking line and the convex portion 313 are aligned again, and another single-sided tape 40 is attached and fixed over the other end skeleton installation portion 33 and the upper surface of the skeleton 1. ..

Next, while inserting the extension portion of the base plate 51 into the opening of the cap tree 2, the cap tree 2 is pushed from above the skeleton 1 and engaged with the holder 6. At this time, by aligning the end surface 25 of the Kasagi 2 with the side surface of the step 315 of the joint portion arranging component 30, the Kasagi 2 can be aligned in the joint portions 3A and 3B.
When the cap tree 2 is pushed in, the fin portion 35 of the joint portion arranging component 30 first comes into contact with the lower surface of the cap tree 2. Then, as shown in FIG. 7, as the cap tree 2 is pushed downward, the fin portion 35 curves in contact with the cap tree 2. Therefore, when the cap tree 2 is pushed in until it engages with the holder 6, the opening at the end portion of the cap tree 2 is closed by the fin portion 35 of the joint portion arranging component 30.
As shown in FIGS. 4 and 8, the cap tree 2 of the present embodiment is inclined so that the inclined surface portion 22 is lower than the central portion 21, so that the fin portion 35 abuts on the inclined surface portion 22. The portion is curved according to the inclined surface portion 22.
As described above, the installation work of the joint portion arranging component 30 and the cap tree 2 is completed, and then the support column 52 is attached to the extension portion of the base plate 51, and the horizontal rail 53 and the vertical rail 54 are assembled between the support columns 52. The handrail unit 5 is assembled by arranging the units and connecting them to the support columns 52.

[Action and effect of the embodiment]
According to the present embodiment, since the fin portion 35 is provided so as to extend outward from the base end portion 351 toward the tip end portion 352, the fin portion 35 hits the cap tree 2 when the cap tree 2 is fitted into the holder 6. While in contact, it is pushed outward and curved. Therefore, the force for pushing the cap tree 2 can be reduced as compared with the case where the cap tree 2 is pushed and compressed as in the conventional wall forming portion, and the construction workability at the site can be improved.
Further, even if the type and dimensions of the cap tree 2 are different, the fin portion 35 can be dealt with by bending, so that the increase in the types of the joint portion arranging parts 30 can be suppressed and the cost can be reduced.
Further, since the pair of side wall portions 312 erected from the bottom portion 311 and the pair of fin portions 35 are provided continuously from the side wall portion 312, the protruding dimension of the fin portion 35 can be appropriately set. That is, when the fin portion 35 is directly provided on the bottom portion 311, the protruding dimension of the fin portion 35 becomes long, so that the fin portion 35 is easily deformed, the contact pressure with respect to the cap tree 2 is weakened, and a gap may be formed. On the other hand, in the present embodiment, since the fin portion 35 is continuously provided on the side wall portion 312, the protruding dimension of the fin portion 35 can be shortened as compared with the case where the fin portion 35 is directly provided on the bottom portion 311. Therefore, it becomes easy to balance the deformability of the fin portion 35 with the contact pressure with respect to the cap tree 2, and it is possible to prevent the occurrence of a gap.

Since the drainage passage portion 310 for draining the rainwater that infiltrates the joint portion is configured by the bottom portion 311 and the pair of side wall portions 312, even if the rainwater invades the joint portion, the drainage passage portion 310 ensures that the drainage passage portion 310 is outside the Kasagi 2. Can be drained.

In the fin portion 35, the surface 353 in contact with the cap tree 2 is subjected to a sliding treatment of applying a synthetic resin to reduce the frictional resistance. Therefore, when the cap tree 2 is fitted to the holder 6, the resistance of the fin portion 35 can be reduced. .. Therefore, the force when pushing the Kasagi 2 can be further reduced, and the construction workability can be further improved.

Since the fin portion 35 is formed in a fin shape and is curved outward, the contact state with the cap tree 2 can be maintained while being further curved as the cap tree 2 is pushed in. Therefore, the contact area between the cap tree 2 and the fin portion 35 can be increased without increasing the thickness dimension of the fin portion 35, and the end opening of the cap tree 2 can be reliably closed by the fin portion 35.
Further, since the tip portion 352 is formed in a substantially arcuate cross section, it is possible to prevent the tip portion 352 from being caught when it comes into contact with the cap tree 2 and increasing the frictional resistance.

The central skeleton installation portion 31 including the drainage passage portion 310 and the end skeleton installation portion 33 are formed of a semi-hard or hard synthetic resin, and the fin portion 35 is formed of a soft synthetic resin. The joint portion arranging component 30 can be easily manufactured by color molding. Further, since the fin portion 35 is made of a soft synthetic resin, it can be easily curved according to the cap tree 2, and the opening of the cap tree 2 can be reliably closed.

Since the joint portion arranging component 30 is configured to include the central skeleton installation portion 31 and the end skeleton installation portion 33, and the groove portion 332 is provided between the central skeleton installation portion 31 and the end skeleton installation portion 33, the central skeleton installation portion 31 A part of the end skeleton installation portion 33 can be cut from the central skeleton installation portion 31 without affecting the drainage ditch 314 of the above. Therefore, even if the end skeleton installation portion 33 is cut, the drainage function of the drainage ditch 314 and the watertightness performance of the fin portion 35 can be maintained.
Further, by cutting a part of the end skeleton installation portion 33 from the central skeleton installation portion 31, a part of the joint portion arranging parts 30 has a configuration in which only the central skeleton installation portion 31 is installed on the upper surface of the skeleton 1. can do. Therefore, in the portion where the end skeleton installation portion 33 is cut, the base plate 51 can be inserted into the groove portion 332 and arranged, and the distance between the base plates 51 arranged across the end skeleton installation portion 33 is minimized, for example, about 12. It can be set to about 5.5 mm. Therefore, the gap size between the columns 52 erected on the base plate 51 can be reduced, and it is not necessary to attach a grid-like design material between the columns to prevent children from slipping through.

Since the groove 331 is formed in the end skeleton installation portion 33, the end skeleton installation portion 33 can be easily and accurately cut along the groove 331. Therefore, a continuous space can be reliably formed in the groove portion 332, and the base plate 51 can be inserted into the groove portion 332.

Since the convex portion 313 is formed at the central portion in the width direction of the bottom portion 311 of the central skeleton installation portion 31, the convex portion 313 can be easily positioned by aligning the convex portion 313 with the line marked on the skeleton 1.
Further, since the convex portion 313 is also used as a central wall portion for forming two drainage grooves 314 between the convex portion 313 and the side wall portion 312, the joint portion arranging component 30 is compared with the case where these are separately provided. The cross-sectional shape can be simplified, and the joint portion arranging part 30 can be easily manufactured by extrusion molding or the like.

Since the drainage ditch 314 has a shape that promotes the capillary phenomenon without generating surface tension, the rainwater that has flowed into the drainage ditch 314 does not stay and can be drained smoothly.

An end skeleton installation portion 33 is formed on the joint portion arranging part 30, and the joint portion arranging part 30 is temporarily fixed with a single-sided tape 40 straddling the skeleton 1 and one end skeleton installation portion 33. Later, the position of the joint portion arranging component 30 can be finely adjusted. That is, since the single-sided tape 40 has elasticity, the position can be adjusted by moving the joint portion arranging component 30 even if the joint portion arranging component 30 is slightly deviated from the marked line. Therefore, as compared with the case where the entire lower surface of the drainage member is used as an adhesive surface, the position of the joint portion arranging component 30 can be adjusted even after the joint portion arranging component 30 is installed on the skeleton 1, and further, one side of the joint portion arranging component 30 can be adjusted. Since the arrangement position of the joint portion arrangement component 30 can be finely adjusted even after being temporarily fixed with the tape 40, workability can be improved.

When the cap tree 2 is attached, the end surface 25 of the cap tree 2 is positioned according to the side surface of the step 315, so that the gap dimension between the end faces 25 of the cap tree 2 is set to the dimension between the side surfaces of the step 315, 10 mm in the above embodiment. can. Therefore, it is not necessary to position the cap tree 2 while measuring the gap dimension between the end faces 25 of the cap tree 2 using a tool such as a steel square, and the cap tree 2 can be easily positioned to improve workability. Can be improved.
