Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a veranda, balcony, hallway or six
4. Handrails for buildings made of hardened cement that are installed on rooftops, etc., and in particular, relate to the structure of the Kasagi support bracket above the pillars.

In the case of conventional handrails that have been replaced with hardened cement, in order to attach the cap to the posts, a bolt for securing the cap is installed at the upper end of the post and projects upward, and a hole for engaging the cap that has been drilled in advance is attached to the bolt. By fitting the support l
The common method was to place and fix a Kasagi.

However, in such a case, when external pressure is applied to the cap, the impact load acts on the cap and the support via the bolts, so the impact load is concentrated on the bolts and the hardened cement, which has different physical properties, is likely to be damaged. The part that fixed it to the pillar had become loose, causing the Kasagi to fall off the pillar.

Present invention 61 In view of the above, the pillars and balustrades constituting the handrail are manufactured using a hardened cement material that is highly formable, and panel-shaped or border-shaped balustrades are secured to both sides and above of the pillars. At the time of molding, the engaging part and the bracket part to support the cape are formed in wood, and also part of the anchor for erecting the support is molded at the same time. In addition to being easy to handle, it also eliminates the need for surface treatment to prevent rust, unlike metal supports and balustrades. The object of the present invention is to obtain a handrail that can withstand long-term use without fear of falling off from the support.

The structure of the present invention will be explained with reference to the embodiments shown in the attached drawings.
Reference numeral 1 denotes a column made of hardened cement reinforced by mixing fibers, etc., with two protruding walls 3 protruding from both sides to which balusters 5 are fixed, and the upper side is open. During molding, an engaging part 4 consisting of a groove, a bracket part 7 supporting the cap 6 on the upper side, and an anchor part 8 implanted at appropriate intervals on the mounting base 2 of a balcony etc. on the lower side. It is formed in one piece.

The bracket part 7 has a concave surface 11 that extends from the upper end of the support column 1 and has a concave surface 11 that is approximately the same as the lower half of the cap 6 that is tightly fitted thereinto, and a concave surface 11 on both side edges of the concave surface 11. The end portions of the two caps 6.6 extending from the left and right sides are connected to the concave surface 11.
The bracket cover 13 is placed on the upper surface of the main body 10 and has a concave surface 11 on the lower side which is the same as the outer shape of the upper half of the cap 6, and the bracket cover 13 is fastened with the fasteners 12 to be mounted and supported. Ru.

It should be noted that continuous caps 6 may be used instead of using the caps 6 (separated for each span between one support 1 and supporting each with the bracket part 7 of the upper frame of the support 1).

Anchor part 8 (1) integrally provided at the lower end of the column 1 (1) A collar-shaped pedestal 15 extending laterally from the lower end and a mounting base 2
The column-shaped embedded part 17 is embedded in the mounting hole 14 provided in the mounting base 2, and the embedded part 17 is fitted into the mounting hole 14 provided in the mounting base 2 and is filled with mortar or the like and then erected. Fixed.

The baluster 5 is made of hardened cement reinforced with fibers or the like, similar to the above-mentioned pillar 1, and is made in the shape of a panel or edge rail. It is attached by locking its both ends with appropriate fasteners.

As shown in FIGS. 2 and 3, the engaging portion 4 of the column 1 that locks the handrail 5 has a strip that is continuous in the vertical direction on both sides and has an opening on the upper side. Form the engaging part 4 from the groove and insert the balustrade 5 from above to engage the IJ-
, as shown in FIGS. 4 and 5, the protrusions 18 at both ends of the handrail 5 are dropped or inserted into the engaging portions 4 that protrude laterally at the upper and lower ends of the column 1, respectively. The hooks may be intricately hooked.

Furthermore, as shown in FIG. 6, the bracket part 7 supporting the Kasagi 6 is constructed by dividing the main body part 10 into left and right parts, and providing a bracket cover 13 on each part to repair or replace each span of each column 1. It is also possible to adopt a configuration that enables this.

In addition, as an example of the anchor part 8 for erecting the support 1, (
1. As shown in FIGS. 7 to 9, an embedded portion 17 made of bent reinforcing bars is provided so as to maintain strength against the mortar filled in the mounting hole. ), an insert pin 23 that can slide vertically at the lower end of the column 1
It is optional to provide this in the embedded portion 17 (FIG. 8), or to provide the engaging portion 4 for locking the handrail 5 and the anchor portion 8 integrally (FIG. 9).

The present invention has the above-mentioned configuration, in which the support column and the balustrade are made of a hardened cement material that is highly formable, and the engaging part for fixing the balustrade and the bracket for supporting the hat. Since the parts, etc. are formed integrally when molding the pillars and handrails, the material cost is low and molding is relatively easy, no special storage space is required, and there is no complicated assembly process, making the handrails very inexpensive. can be obtained.

Additionally, installation work at the construction site is very simple and economical, reducing labor costs.

In addition, there is no rust, which is the biggest drawback of conventional metal handrails, and there is no need for surface treatment to prevent rust, and it can withstand long-term use. etc. can be easily performed.

Then, instead of directly fixing the Kasagi to the support using fasteners such as bolts with different physical properties, the Kasagi is mounted by tightly fitting between the bracket part above the support and the concave surfaces of the bracket cover, and the entire concave surface is The structure was designed so that the impact load is dispersed and absorbed and the mounting condition is maintained, so even in the case of a Kasagi that has been replaced with cement hardening, like the pillar, the parts where the pillar and Kasagi are attached will be partially damaged and the Kasagi will be damaged. It can withstand long-term use without fear of causing it to fall off.
