Abstract

PURPOSE:To facilitate the work of a framework, by inserting core rods fixed saliently on to structure framework into the struts of a handrail main-body, and by fixing both ones with the injection of a hardener. CONSTITUTION:In holes bored through a structure framework 6, core rods 7 are saliently fixed by an adhesives. A handrail main-body 1 has cylindrical struts 2, a head frame 3, a bottom frame 4, and rail members 5, and the struts 2 are externally fitted on the core rods 7. Then, by injecting the hardener through the slots 12 of the head frame 3 of the upper section of the struts 2, the core rods 7 and the struts 2 are firmly fitted on each other. After that, by fitting a coping on the head frame 3, the slots 12 are covered with the coping.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a handrail constructed using a retrofit construction method.

(Prior Art) Conventionally, in order to attach a handrail to a building frame, as shown in Figs. 6 to 9, a formwork 31 is provided before concrete is poured into the building frame, and anchors 32 are placed at predetermined locations. A fence 33 is provided above the anchor, and then concrete 34 is poured (FIG. 6). As a result, building frame 3
5 is formed by burying an anchor 32, and a space 36 without concrete is formed above the anchor (FIG. 7). In this space 36, the anchor 32
A column reinforcing material 37 is welded to the upper surface via a support metal fitting 38, and a column 39 is fitted onto the column reinforcing material 37 (Fig. 8). After that, the space 36 is filled with resin mortar 40 to finish it (Fig. 8). Figure 9). As a result, the pillar 39 is connected to the pillar reinforcement member 37.
and resin mortar 40 for reinforcement and support.

(Problems to be Solved by the Invention) The conventional method of installing handrails mentioned above is one in which the handrails are planned to be installed in advance when the building frame is poured. It was constructed using the construction method shown below.

In this construction method, the mounting bracket 22 is fixed to the building frame 21 with bolts and nuts 23, and the lower part of the support 25 of the mounting bracket 22 (ζ handrail body 24) is fixed with bolts 25 and nuts 26. The above retrofitting method uses the mounting bracket 22 and two types of bolts and nuts 23 and 25.2.
6, the reliability of the installation was lacking, and the assembly was troublesome.

The present invention has been made to provide a handrail and a method for manufacturing the same that solves the above problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a first invention comprising: a mandrel protrudingly fixed to a building frame; a pair of cylindrical pipes attached to the mandrel; It consists of a pillar, a top and bottom frame, a cap that is attached to the upper azusa, and a handrail body equipped with a sash wood.
The pillar has the mandrel inserted in its lower part and is fixed to the mandrel through a fixing agent, and the upper frame has a handrail having a hole for injecting the adhesive at a portion where the upper end of the pillar abuts. In addition, as a second invention, a hole is bored in a building frame, a mandrel is inserted in a chain type, and then the mandrel is protruded and fixed to the building frame with an adhesive. A handrail main body is formed which includes an upper frame having a hole for injecting a fixing agent at a portion where the upper end of the support comes into contact, a lower frame disposed between the support supports, and a slat material. It is an object of the present invention to provide a method for manufacturing a handrail in which a support post is fitted onto the mandrel, a fixing agent is injected through the hole in the upper frame, and then a cape is attached to the upper frame.

(Function) A hole is drilled in the building frame, adhesive is injected in a chain style, and a mandrel is inserted in a chain style, so that the mandrel protrudes and is fixed to the building body by the adhesive. - On the other hand, since the support of the handrail body is cylindrical, it can be attached by simply fitting the support onto the mandrel. Since a hole is provided in the upper part of the part where the upper end of the strut comes into contact, if the adhesive is injected through the chain hole, the adhesive will flow into the external fitting part of the mandrel, and this adhesive will cause the mandrel and the strut to be connected. Fixation is made.

After that, by attaching a cap to the upper frame, the hole is hidden by the cap, and a handrail with a good appearance and strong mounting strength is obtained. Furthermore, in the present invention, there is no need for screwing work at all, and there is no need to prepare mounting fittings depending on the building frame.

(Example) Hereinafter, the present invention will be explained based on one example diagram of FIGS. 1 to 4.

Figure 1 is an overall perspective view, Figure 2 is a perspective view showing how the mandrel is fixed, Figure 3 is a partially cutaway perspective view showing how the handrail is constructed, excluding the cap, and Figure 4 is the cap and upper frame. FIG.

In the figure, reference numeral 1 indicates a handrail main body, and the handrail main body 1 is composed of a pair of left and right supports 2, 2, upper and lower frames 3, 4, and a plurality of beams 5 fixed between the upper and lower frames 3, 4. ing.

Reference numeral 6 indicates a building frame, and 7 indicates a shaft protrudingly fixed to the building frame 6. Specifically, the mandrel 7 is made by drilling a hole 68 in the building frame 6, injecting adhesive 9 into the hole 8, and inserting the mandrel 7 into the hole 8 of the same size. It is fixed to the building frame 6 as a protrusion from the building frame 6.

The handrail main body 1 is attached to the building frame 6 via the above-mentioned mandrel 7 and a fixing agent 11 such as resin mortar, which will be described later.

That is, the hollow part 1 serves as the support 2.2 of the handrail main body 1.
0 is used, the mandrels 7, 7 are inserted into the lower parts of the struts 2.2, respectively, and under this condition the struts 2, 2 are inserted.
A fixing agent 11 such as resin mortar is injected into the inside, and the handrail body 1 is attached to the building frame 6 via the mandrel 7 and the fixing agent 11.

12 is a fixing agent injection hole, and the fixing agent injection hole 12 is
It is inserted through the upper frame 3 in order to inject the adhesive 11 into the column 2.2. Reference numeral 18 denotes a cover, which is formed at the upper end fixed portion of the support column 2.2.

Therefore, in the above-mentioned embodiment, although the fixing agent injection hole 12 is formed in the upper frame 3 and the fixing agent 11 can be easily injected, there is a problem that it is unsightly. In order to solve this problem, a cap 13 is fitted onto the upper frame 3. In the illustrated embodiment, in order to facilitate the attachment of the cap 13 to the upper frame 3, the cap attachment structure of the upper frame 3 and the cap 13 is devised.

Specifically, a locking portion 14 facing outward is provided on the upper surface of the upper frame 3.
A wedge strip 15 is provided protrudingly having
A flexible curved system 17 is formed with inwardly directed locking portions 16. After the handrail body 1 is attached, the cap 13 is fitted onto the upper frame 3 by pressing it from above.

Note that the adhesive injection hole 12 may be provided through the side wall of the support column 2.2, and in this case, the cap 13 is not necessarily required.

(Effects of the Invention) As explained above, according to the present invention, there is no need for mounting fittings and there is no need to perform screwing work. The length and diameter of the mandrel used in place of the mounting bracket is determined by its relationship with the support column, and only one type needs to be prepared to match the handrail itself, regardless of the building frame. Advantages include: Injecting adhesives and fixing agents is easier than using screws. Furthermore, the adhesive injection hole is hidden by the cap, making it possible to obtain a handrail with good appearance and appearance.
