Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to a handrail that is installed and fixed to a building frame, such as a rooftop parapet such as reinforced concrete or ALC, or a rising wall of a balcony or hallway. This relates to a substantially U-shaped handrail holder in Kasagi.

(Background technology) Conventionally, in this type of handrail cap, mounting bases are fixed at predetermined intervals in the longitudinal direction of the building frame, and a handrail holder is placed and fixed on the mounting space position via a long cap, and the handrail pillar is erected. There are known methods for setting and fixing. However, from the viewpoint of safe installation of the handrail, this handrail holder is a painted box-shaped integral cast product with an opening only at the top for receiving the handrail post. This has no problem in that it has excellent handrail holding strength and is easy to achieve dimensional accuracy, but its manufacturing cost is high, so regardless of the product grade, there is not much difference in cost for the handrail holder part, and it is difficult to develop the product. It was becoming a bottleneck.

In addition, since handrail-equipped caps are installed outdoors, they are exposed to wind and rain, but with the box-shaped integral cast holder, rainwater that has entered the holder is difficult to drain even if drainage holes are provided, and it accumulates at the bottom. In addition, the handrail posts and holders themselves are at risk of corrosion, which poses a safety problem, especially on handrails on which people may place their weight.

(Objective of the Invention) The present invention enables the material change of the conventional handrail holder of this kind, and also provides a new handrail cap that is relatively low in cost and free from accumulation of rainwater and therefore free from corrosion. The object of the present invention is to provide a substantially U-shaped handrail holder.

(Structure of the Invention) In view of the above-mentioned objects, the present invention makes a handrail holder made of a molded material by extrusion molding of various materials, molds this molded material to obtain two upper and lower handrail holders, and cuts the molded material. In other words, the present invention uses a predetermined long extrusion-molded material such as aluminum alloy, synthetic resin, or ceramic material, which has a substantially H-shaped cross section with side walls on both sides of a central thick substrate and is vertically symmetrical. A capstone with a handrail, characterized in that the short material is cut into lengths, the central thick-walled substrate of the short material is cut diagonally at the intermediate portion, and a predetermined process such as hole cutting is performed thereon. The gist is a substantially U-shaped handrail holder.

By the way, the reason why the present invention employs a structure in which the above-mentioned two handrail holders, upper and lower, are formed and separated by diagonal cutting is as follows. That is, the cap of a handrail-equipped cap is generally sloped from the outside to the inside so that rainwater does not flow toward the outside wall of the building, which is not waterproofed, and instead guides rainwater to the inside, which is waterproofed. Since the handrail holder is placed and fixed on this capstone, its lower surface should have a slope that matches the slope of the capstone to stabilize its fixation, but it is necessary to provide the slope of the lower surface of the handrail holder, especially in the longitudinal direction of the shape material. Sometimes, in extrusion-molded materials having the same cross section in the longitudinal direction, this cannot be obtained directly, and it is unavoidable to process the gradient later. Therefore, the present inventor obtained this as a molded material with upper and lower parts integrated, and then converted it into -
This is because the separation and installation of the slope are to be performed at the same time in one cutting.

The present invention will be described below with reference to drawings showing embodiments. In FIGS. 1 to 4, 1 is an extrusion-molded elongated member made of aluminum alloy, and this elongated member 1 is attached to a central thick substrate 2. A cross-sectional path H is integrally formed with side walls 3 and 3 on both sides, respectively.
It is shaped like a letter and is vertically symmetrical. This elongated member 1 is further provided with a narrow groove 4 on the opposite surface of the side wall 3.3, and its dimensions are approximately 15 mm in height and approximately 6 mm in width.

This extrusion-molded elongated material 1 has a predetermined length in its longitudinal direction.
For example, it is cut into about 11 cIn to obtain the short shape material 5. Then, as shown in FIG. 2, the four corners of the short material 5 are cut and removed before or after the ear portions 6 are removed. Mold material 1
The substrate 8 is cut diagonally in the longitudinal direction of the blade, that is, in the extrusion direction, and is separated into upper and lower parts into each handrail holder 7.7, and the lower surface of the substrate 8 in each handrail holder 7 is provided with an inclined slope. Furthermore, the board 8 has two elongated holes 9 for bolt insertion, and the side wall 3.3 has through holes 10 and 10 for screws, respectively.
By drilling and providing two holes on each side, a substantially U-shaped handrail holder 7 is completed.

The handrail holder 7 thus provided is used as shown in FIG. That is, the handrail holder 7 is mounted on a mounting base 12 which is fixed to a steel angle member 11 forming the building frame by welding or hole-in anchors, with a top plate portion of a long aluminum upside-down U-shaped cap 13 interposed therebetween. 13
These kings are placed on top of the handrail holder 1 perpendicularly to the longitudinal direction, and are fixed integrally by bolts and nuts 14. A handrail post 15 is inserted between the side walls 3, 3 of the handrail holder 1, and a handrail post 15 is inserted from the outside of each side wall 12. They are used by being fixed to iron cores 16 inserted into the inside of the handrail column 15 through the through holes 10 with threaded screws 17, respectively.

In the figure, reference numeral 18 denotes a cap that is fitted between the narrow grooves 4, 4 of the handrail holder 7 at the front and back thereof and also serves as a cover for the bolt nuts 14.

On the other hand, FIGS. 5 and 6 show other embodiments,
Since their basic configuration is the same, they are indicated by the same numbers as above with a dash, but to explain the difference, this approximately U-shaped handrail holder 7' is attached to the left and right side walls 313'.
A groove 19 facing upward is provided in the groove 19...
The open end of the handrail holder 7' is closed with a separate member by fitting wedge-shaped closing plates 20, 20 into the grooves 21 in an erected manner, and the mounting base 12 to the building frame.
' is fixed by a hole-in anchor 22, and a blind plate 24 is fitted between the upper and lower fitting grooves 23 of the side walls 3, 3 on the outside of the threaded screw 17'. Of course, in this case, the extrusion-molded elongated material is made by combining the handrail holders 7' vertically, but compared to the handrail holders, processing is not limited to hole drilling, but requires groove processing.

By the way, in addition to aluminum alloy, the handrail holder of the present invention uses a material that can be extruded, such as a hard synthetic resin containing glass fiber or a ceramic material. The diagonal cutting to obtain the handrail holder is not limited to the diagonal cutting in the longitudinal direction of the elongated material in the above two embodiments, but can also be diagonal cutting in a direction perpendicular to this.

At this time, the orientation of the handrail holder is changed by 90 degrees, and the open end side is installed with its open end facing the handrail hat in the left-right direction. In this case, each single extrusion molded elongated member can be formed with a slope on the bottom surface during molding, but according to the present invention, twice as many handrail holders can be obtained per extrusion molding, so production is reduced. There is a big cost advantage.

On the other hand, when making a short profile material, diagonal cutting at the middle part of the central thick board can be done with a cutter, and other processing can be done using general mold processing, but when cutting the edge part is required, this method is used. The order can be changed, and some or all of them can be performed at the same time.

It goes without saying that the present invention is not limited to the above-described embodiments, and that the material, specific shape and structure, addition of other parts, etc. can be changed in various ways as long as they do not go against the gist of the invention.

(Effects of the Invention) The present invention is made by cutting an extrusion-molded long shape material into a predetermined length into a short shape material, which has an 8-section shape with 4 side walls on both sides of a central thick substrate and is vertically symmetrical. , the central thick board is diagonally cut at the middle part, and the predetermined processing is performed on it, so that the diagonal cutting described above separates the two upper and lower handrail holders and installs the bottom surface in a single cut. The production is extremely efficient as both can be achieved simultaneously. Furthermore, by using extruded material, it is easy to achieve precision in each part, including the dimensions between the side walls, and together with the above-mentioned increase in production efficiency, the production cost can be reduced. Furthermore, in addition to the simple U-shape, it is relatively easy to design and produce by attaching parts etc. to give it a high-class feel. suitable for

On the other hand, since the handrail part of the handrail with a cap can be held on at least two sides, its fixing strength can be ensured without any worries, and
Even if rainwater or the like gets inside the handrail holder, even if the end face is blocked, drainage is good because it is a separate member, and it is possible to prevent water from accumulating inside and corroding the handrail post.
