Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a reinforcement arrangement method for columnar reinforcement.

(Prior art) Column reinforcements for reinforced concrete structures include: - a plurality of column main reinforcements erected in a membrane, and a plurality of hoop reinforcements arranged at predetermined intervals in the vertical direction around the outer periphery of the column main reinforcements. These reinforcing bars are integrally bound together by wire.

In such a column reinforcement structure, a method of assembling the inside of the membrane at the construction site has been adopted, and the reinforcement has conventionally been arranged using the method described below.

First, the spacing of hoop reinforcements is set by each company, so after attaching a mark that matches the spacing to the main reinforcement of the column,
Insert the required number of annular hoop reinforcements from above the erected column main reinforcements.

Then, the inserted hoop reinforcements were pulled upward one by one, placed at the above-mentioned landmarks, and tied to the column main reinforcements. This process was repeated.

However, the column reinforcement arrangement method performed in such a process has the following technical problems.

(Problem to be Solved by the Invention) In other words, in the conventional reinforcement method described above, circular hoop reinforcements are tied sequentially from the upper side of the column main reinforcement, but two or three stages of hoops are connected to the upper side of the column main reinforcement. When you tie the muscles together,
The main column reinforcement is positioned on the inner periphery of the hoop reinforcement, and the mutual spacing is regulated.

For this reason, if you try to lift the hoop reinforcement upwards after that, the inner periphery of the hoop reinforcement will come into contact with the outer periphery of the column main reinforcement, making it difficult to raise it to the set position, and construction efficiency will not increase. There was a problem.

Further, there was also the problem that the work of attaching a plurality of marks to the main column reinforcement according to the installation intervals of the hoop reinforcement was troublesome and prone to mistakes.

This invention was made in view of these conventional problems, and its purpose is to enable accurate reinforcement without any troublesome work, and to greatly improve construction efficiency. The purpose of this invention is to provide a method for arranging columnar reinforcement.

<Means for Solving the Problems> In order to remotely achieve the above object, the present invention arranges a plurality of annular hoop reinforcements at predetermined intervals in the vertical direction on the outer periphery of a plurality of erected column main reinforcements. In the method for arranging column reinforcements that binds the hoop reinforcements and the column main reinforcements, a gauge member is provided with a step-shaped locking part that can be retracted and retracted at a position corresponding to the interval on the outside of the column main reinforcements. are installed facing each other, and after the hoop reinforcement is locked to the locking portion, the hoop reinforcement and the column main reinforcement are tied together.

(Operation and Effect of the Invention) According to the reinforcement arrangement method having the above configuration, a cage member provided with a retractable locking portion is installed at a position corresponding to the installation interval of the hoop reinforcement, and the hoop reinforcement is attached to the locking portion. Since the hoop reinforcements are locked, the hoop reinforcements can be accurately placed in relation to the column main reinforcements.

In addition, the hoop strips are sequentially lifted upward with the locking portions of the cage member retracted, and then the locking portions are pulled out and locked, and after all the hoop strings to be installed are locked, they are tied together. Therefore, it is avoided that the main reinforcement of the column is restricted by the bundling of the hoop reinforcements, which makes it difficult to install the hoop reinforcements, as in the conventional method, and the efficiency of reinforcing reinforcement is greatly improved.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1 and 2 show an embodiment of the method for arranging column reinforcement according to the present invention.

The reinforcement arrangement method shown in the figure is applied to the reinforcement arrangement of a column member formed into a substantially square shape, and four main column reinforcements 10 are placed upright at each corner of the square. ing.

A necessary number of rectangular annular hoop reinforcements 12 are inserted from above into the erected column main reinforcements 10 and stacked on the floor.

Next, the column main reinforcing bars 10 are extended upward by pressure welding, joints, mechanical joints, or the like.

In this state, in the reinforcement arrangement method according to the present invention, a pair of cage members 14 are installed at opposing positions outside the column main reinforcement 10.

The cage member 14 includes a seating plate 14a installed on the floor;
A pair of pillars 14b are erected to face each other on the seating plate 14a, and a locking pin 14 is provided on each pillar 14b.
It is composed of c.

A plurality of locking pins 14c are provided in a stepped manner along the longitudinal axis of the column 14b, and the vertical interval of each locking pin 14C is equal to the interval between the hoop reinforcements 12 installed on the outer periphery of the main column reinforcement 10. The intervals between the horizontally adjacent locking bins 14c are narrower than the intervals between the column main reinforcements 10.

Further, each locking pin 14c has a stop bar formed at both ends, and is configured to be inserted into a hole formed in the support column 14b so as to be able to come out and retract.In the installed state of the cage member 14, each locking pin 14c The column main reinforcement 10 has a column 1.4 on the outside side.
It is recessed so as to protrude from b.

When the installation of the cage member 14 is completed, one or two cage members are inserted from the upper side of the stacked hoop bars 12.
Lift up the three bars at the same time, and make them protrude in sequence from the upper locking pin 14c toward the column main reinforcement 10 side, so that the hoop reinforcement 12
Each book is locked and supported between the locking bins 140.

When all of the hoop reinforcements 12 are locked and supported by the locking pins 14c, each hoop reinforcement 12 is tied to the column main reinforcement 10 by wire, and when the cage member 14 is removed, the reinforcement arrangement of the column reinforcement is completed.

Here, when removing each cage member 14, if a plate material for height adjustment is inserted between the seating plate 14a and its installation surface, by removing this plate material, each locking member can be adjusted by that amount. Since the position of the pin 14c is shifted downward, the locking pin 14c can be easily removed without being recessed.

Now, in the reinforcement arrangement method performed in the above steps, what is particularly noteworthy is the locking pin 14 that locks and supports the hoop reinforcement 12.
Since the vertical spacing of c corresponds to the spacing between the hoop bars 12 to be installed, not only can the spacing be set accurately just by supporting the locking pins 14c, but also each of the locking pins 14c The hoop reinforcements 12 are recessed and retracted to the outside of the column main reinforcement 10, so they do not become an obstacle when lifting the hoop reinforcements 12. For these reasons, the construction method is significantly easier than the conventional reinforcement reinforcement method. Improves efficiency.

In addition, although the above-mentioned example illustrated the case where the present invention is applied to a column member of 6 shapes, the implementation of the present invention is not limited to this, and the reinforcement arrangement of a column member of other shapes such as circular It can also be applied to
