Description

[Detailed description of the invention] 3. Scope of claims (Industrial application field) The present invention relates to a mounting structure for a handrail hat.

(Prior art) Generally, Kasagi are installed on a plurality of holders arranged at regular intervals on the upper surface of the parapet of a building frame, but handrail Kasagi where handrail pillars are integrally installed on the top of Zara Kasagi. In some cases, the base of the handrail post is fixed to a mounting member placed on the back side of the top plate of the Kasagi, and the mounting member is usually supported by a holder. However, while the mounting member support part of the holder is formed horizontally with the top surface of the parapet, the top plate of the Kasagi is sloped downward toward the inside of the building frame, so the top plate of the Kasagi and the holder are not parallel. For this reason, the mounting member must be made into a special asymmetrical shape depending on the non-parallel state of the top plate and the holder, which is cumbersome to process, and also when fixing the handrail column to the mounting member.
It was very troublesome because the mounting member had to be aligned in a predetermined direction and the screws 1 had to be screwed in.

(Technical Problem of the Invention) The present invention solves the drawbacks mentioned in -, and provides a simple structure for firmly supporting and holding the mounting member, as well as a handrail cap that can be easily fixed. Its purpose is to provide structure.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the handrail cap mounting structure according to the present invention has a plurality of holders mounted at regular intervals on the upper surface of the balustrade of the building frame, and a plurality of holders mounted on the holders at regular intervals. A capstone with a top plate that slopes downward toward the inside of the building frame is provided relative to the top surface of the parapet and the holder, and both sides of the capstone are secured to both sides of the holder, and handrail posts are installed at predetermined intervals on the top of the capstone. In the handrail kasagi arranged above, a support part having an inclined surface corresponding to the inclination of the kasagi top plate is formed on the upper part of the holder, and a mounting member arranged on the back side of the kasagi is stored and supported on the support part. In addition, the handrail post on the cap is fixed to the mounting member.

(Operations and Effects of the Invention) As described in E, according to the present invention, a support portion having an inclined surface corresponding to the inclination of the Kasagi top plate is formed on the upper part of the holder, so that the relationship between the Kasagi top plate and the holder is This will form a plane parallel to the support surface of the support portion. Therefore, the mounting members for the handrail pillars placed on the back side of the Kasagi top plate can be formed in a symmetrical shape, which simplifies processing, and the orientation of the mounting members is also taken into account when fixing the handrail pillars to the Kasagi top plate. Since there is no need for it, the work can be done easily, and the construction period for Kasagi can be shortened. Also, since the mounting parts are placed and supported on the support part of the holder, they are very stable. death,
Handrail pillars on the Kasagi can be supported reliably.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the symbol A indicates a handrail cap. This handrail cap is made by attaching a plurality of holders 2 at regular intervals to the upper surface of the parabet 1 of the building frame B, and placing a ceiling on these holders 2 that slopes downward toward the inside of the building frame B with respect to the upper surface of the parabet 1 and the holders 2. A cap 3 having a plate 3a is provided, the cap 3 is fixed to the holder 2, and handrail posts 4 are arranged at regular intervals on the top of the cap 3.A handrail is provided at the upper end of each handrail post 4. 5 is provided.

The holder 2 is a short member, and includes a base piece 2a arranged on the upper surface of the parapet l, side pieces 2b, 2b protruding diagonally downward from both sides of the base piece 2a, and a pair formed on the top of the base piece 2a. The base piece 2a is fixed on the parapet 1. The upper surface 6a of the support part 6 is
It is formed so as to be flush with a surface parallel to the inclined surface of the top plate 3a of the Kasagi 3, which will be described next. In addition, both the above-mentioned support parts 6
．． A protrusion 7.7 for positioning is formed at the outer end of 6.

The Kasagi 3 consists of a top plate 3a that slopes downward toward the building frame B side with respect to the horizontal rosette 1, and side edges 3b, 3b that hang down from both sides of the top plate 3a, and the lower ends of the side edges 3b, 3b A bent portion 3C13C is formed.

Next, the handrail post 4 is a cylindrical member made of extruded metal material, etc.
Bisholes 1O are formed inside in the longitudinal direction.

The handrail post 4 is fixed by inserting a mounting member 9 arranged on the back side of the top plate 3a of the Kasagi 3 and screwing a screw 11 passing through the top plate 3a into a screw hole 10.

As shown in FIG. 3, the mounting member 9 is made by bending a metal plate into a U-shape, and includes side pieces 9b facing both sides of a central piece 9a;
A notch is formed in the center of 9b, and a screw 12 for fixing the handrail post 4 is inserted into the screw hole 9c of the center piece 9a.

Holder 2 holds Kasagi 3 with handrail post 4 fixed as described above.
To attach the cap to the parapet 1, press the cap 3 downward from the top of the holder 2 disposed on the parapet 1.
The lower end bent portions 3C13C of the side edges 3b, 3b may be elastically engaged with the side pieces 2b, 2b of the holder 2 while sliding along the outer surfaces of the side pieces 2b, 2b. At this time, the side plates 9b, 9b of the mounting member 9 of the first handrail post 4 are set to be placed on and supported by the upper surfaces 6a, 6a of the support portion 6.6 of the holder 2.

Furthermore, handrails 5 are arranged at the upper end of the handrail column 4 at regular intervals. In this case, for example, as shown in FIGS. 2 and 7(a) and 7(b), a mounting plate 15 is fixed to the upper end of the handrail post 4 with screws 16, and the mounting plate 15 is attached to the bottom surface of the handrail 5. While engaging the recess 17, the mounting plate 1
The screw 18 inserted from below 5 may be fixed by passing through the groove 19 formed in the recess 17 and screwing into the stopper 20.

” Like a double series, a support portion 6.6 having an inclined surface corresponding to the slope of the Kasagi top plate 3a is formed on the upper part of the holder 2, so that the support portion 6.6 of the top plate 3a and the holder 2 support surface 6
a and 6a form parallel surfaces. therefore,
Mounting member 9 for handrail post 4 placed on the back side of Kasagi top plate 3a
can be formed into a symmetrical shape as shown in FIG. Since there is no need to consider the above, the work can be carried out inside the cylinder, and the construction period can be shortened in the construction of the cap 3. In addition, the side pieces 9b of the mounting member 9 are attached to the support part 6 of the holder 2. Since it is placed on and supported by .6, it is well stabilized and can reliably support the handrail post 4 on the cap 3.

Note that the mounting member 9 on the support portion 6.6 is stably held without being displaced by the positioning protrusion 7.7. Further, the protrusion 7.7 also serves as a receiving portion for the Kasagi top plate 3a.

Next, the configuration of the holder 2 is not limited to the above example. For example, as shown in FIG. 4, the side pieces 2b, 2b are further extended obliquely downward from the end positioning/top plate receiving part 7.7 of the support part 6.6 provided on both sides of the base piece 2a. It may be. In this case, the elasticity of the side piece 2b is improved. Alternatively, as shown in FIG.
．． 22, the center holder 21 is formed into a cylindrical or channel shape, and the side holders 22 and 22 have an insertion part 23, a support part 6, a top plate receiving part 7, and a side piece 2b, respectively.
and a central holder 21 fixed to the parapet 1.
The insertion portions 23 of the both side holders 22 may be inserted into both ends of the holder to form an integral structure. Such a long holder 2 is suitable when the parapet 1 is wide. In this case, as shown in FIG. 6, both side holders 22.
