Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for erecting supports such as handrail units.

[Conventional technology]

When replacing a balcony handrail, fence, etc. with a new one, a common method is to use the existing handrail supports as anchor members without removing them, and then erect a new handrail on these.

Additionally, recently, when installing handrails and the like in order to improve work efficiency, a method is being used in which pre-assembled finished products are installed in one go, rather than assembling each part one by one. .

An example of this type of construction method is described in Japanese Patent Application Laid-Open No. 57-174574.
A fixed auxiliary column 5 is fixed to the column 1 with the column 1 fitted thereon, and then a column 6 of the newly installed handrail C is fitted on the outside of the fixed auxiliary column 5 so as to fit closely together. It is.

[Problem that the invention seeks to solve]

However, according to this type of construction method, when fixing and positioning the fixed auxiliary column 5, and adjusting the position of the column 6 of the newly installed handrail C, it is necessary to interpose 10 and 10' between the column 1 and the fixed auxiliary column 5. Not only is the work extremely troublesome, but accurate positioning of the support column 6 is not possible.

Furthermore, according to this type of construction method, in some cases, it may not be possible to install handrails or the like in a completed state.

This invention was proposed to solve the above-mentioned conventional problems, and when installing balcony handrails, fences, etc., it is possible to extremely easily install pre-assembled handrail units, etc. The purpose is to provide a method for erecting supports such as handrail units.

[Means for solving problems]

In this invention, an anchor member is provided protruding from a frame, and an adjustment washer having a hole with a diameter larger than the diameter of the anchor member and a fixed washer having a hole with a diameter approximately equal to the diameter of the anchor member are respectively inserted into the anchor member. Then, the adjustment washer is positioned, followed by the anchor member and the adjustment washer.

The above object is achieved by welding between the fixed washers and then bolting the post of the column base hardware and the handrail unit to the adjustment washer.

〔Example〕

Hereinafter, the method for installing a support such as a handrail unit according to this application will be explained step by step.

■ Aco/car members 2 are installed protrudingly at regular intervals on the upper end of the rosette 1 of a balcony, etc. (see Figure 1)
.

Anchor member 2. ... are part of the foundation reinforcement and existing handrail support.

When the anchor member 2 is used as a foundation reinforcement, the foundation reinforcement may be placed in advance during the construction of the balcony frame, or it may be placed after the construction of the skeleton is completed.

■ Next, each anchor member 2. Insert the adjustment washer 3 into ..., and then insert the fixed washer 4 over it (Fig. 1,
(See Figure 2).

The adjustment hole 3a of the adjustment washer 3 is formed to have a much larger diameter than the diameter of the anchor member 2, and as a result, the adjustment washer 3 can be moved back and forth and left and right over a considerably wide range while being inserted into the anchor member 2. It is possible. - On the other hand, the hole 4a of the fixed washer 4 is formed to have a diameter almost equal to the diameter of the anchor member 2, and as a result, although the fixed washer 4 can be inserted into the anchor member 2, it cannot be moved back and forth or left or right. It is.

■ Next, insert the column base metal fittings 5.5 onto the adjustment washers 3.3 into the lower ends of the columns 7, 7 of the handrail 9 unit 6, and while temporarily fixing them with the fixing bolts 8, 8, attach the handrail υ.
Install it together with unit 6 (see diagram 3).

■ Next, move the adjustment washers 3.3 back and forth and left and right with the column base metal fittings 5, 5 slightly lifted, and adjust each adjustment washer 3.
The positions of the adjustment washers 3, 3 are adjusted so that the adjustment washers 3, 3 are located approximately at the center of the column base metal fittings 5, 5. After completing the positioning, mark the mark (see Figure 3).

■ Next, the column base metal fittings 5, 5 are temporarily removed together with the handrail unit 6.

(2) Next, weld the anchor member 2 and the four fixing washers and the fixing washer 4 and the adjusting washer 3 in alignment with the marked position of the adjusting washer 3 to fix the adjusting washer 3 (see FIG. 4).

■ Next, place the column base hardware 5 on top of the adjustment washers 3, 3 again.
5 together with the handrail unit 6, and adjust the adjustment washers 3, 3.
By welding the base metal fittings 5 and 5, respectively, the handrail stem 6 is installed at the upper end of the rosette 1 (see Figure 5).

■ Next, temporarily remove the temporary fixing port 8, drop the handrail unit 6, and then tighten the fixing port 8, 8 again.
The 9-hand Mold unit 6 is permanently fixed by screwing together (
(See Figure 6).

Furthermore, caulking or mortar 9 is applied to the entire circumference of the lower end of each support column 7, 7, and the adjustment washer 3 is completely embedded (see Figures 1' and 6).

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

■ Even if the spacing between the columns of the handrails etc. to be attached and the spacing between the anchor members protruding from the frame are slightly different, this gap can be easily adjusted and the columns of the handrails etc. can be built very easily. Can be attached. Therefore, handrails, fences, etc. can be attached even in the state of a completely assembled finished product, and workability can be improved.

■ It is also extremely easy to replace existing handrails with new handrails.

Claims (1)

[Claims] An anchor member 2 is provided protrudingly from a frame, and the anchor member 2 has an adjustment washer 3 having a hole 3a having a diameter larger than the diameter of the anchor member 2, and a hole 4a having a diameter substantially equal to the diameter of the anchor member 2. Insert each washer 4, then position the adjustment washer 3, then weld the anchor member 2, adjustment washer 3, and fixing washer 4, and then weld the column base hardware 5 to the adjustment washer 3. A method for installing a support for a handrail unit or the like, which comprises: then bolting the support 7 of the handrail unit 6 to the base hardware 5.
