Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for striation of circular bars in a No. 1 reinforced concrete structure using circular bars as distribution bars.

[Conventional technology] Center joint lEg type or Grakenote type iron 1 = 1 beam? (11') for iron made of 4, etc., with 2 legs in the 1' direction.
It is being joined to the L to create a steel-framed, reinforced conocrete building.

[The point of inventing or trying to solve]

In this case, an annular nucleus 1) 75 or I! is formed in an annular shape as a distribution reinforcement on the outer periphery of a vertically arranged steel frame. tj,
This type of annular Φj should be used because it is often used as an annular reinforcement that has been pre-articulated into a triangular shape.It is not possible to insert the annular reinforcement between two upper and lower steel beams. Kadeki/, [I.

As shown in Figure 1, it is common for a predetermined reinforcing bar f to be used as a stirrup in a circular shape. However, as shown in Figure 6 (a+), the structure that is separate from the top is 7 nodes, and is 4d or more, 8a or more (edashi,
d is the diameter of the reinforcing bar), and Fig. 6 (bl t7
If it is made of one wooden reinforcing bar like ', it can be used as a hook.
A or more is required, and if it is composed of two reinforcing bars like No. 6
A hook of d or more was required.

The same is true when using the hoop muscle, as shown in Figure 7 fat
(requires a hook of 4a or higher, and
As shown in Figure [bl], when arc welding is used, an overlapping portion of 10 d or more is required for the joint when cutting the annular shape.

In this way, it is necessary to have 7 circles or overlapping parts in the circular muscle, which not only makes the circular muscle heavier, but also makes it difficult to converge. ? There is a drawback of f-wana t and r-nana.

[Means for solving problems]

The present invention has been devised to solve these drawbacks, and involves fitting a large number of annular rings around the outer periphery of a steel frame, and placing beams at different positions i1f in the height direction of the steel frame. In some cases, when fixing a bracket for connecting a beam, a large number of annular bars are divided into sets of rollers, a part of the beam or a bracket for connecting the beam is placed between them, and the bracket is tightened and fixed to the steel frame. Vertical iron inwardly of each circular muscle,! After that, insert the sphenoid muscle of each group so that there is a predetermined interval above and below.
and are connected to the vertical reinforcing bars respectively.

In addition, in this EIElfj [l fJ, the annular reinforcement refers to a thick reinforcement such as a stirrup or a hoop reinforcement whose contacting end portions are marked with @ and are annularized into one ring.

[For production]

When this construction method is adopted, the joint ends must be melted to each other in advance, and the parts that are made into a ring in the vertical direction, which is part of a steel-framed reinforced concrete structural column. This makes it possible to place reinforcement around the steel frame where the reinforcement is placed.

〔Example〕

The invention will now be described based on practical examples and the accompanying drawings.

The steel frame (1) used, which is made of H-beam steel, etc., has a predetermined dimension, for example, the height of the steel frame ill of 2 feet in the direction J as a medium method that fits the height of 2 stories or 31 suspended floors! Beam at position X-2)
In fixing the graget which sells the beam 12), a large number of annular bars (31), which have been made into an annular shape in advance, are fitted around the outer periphery of the steel frame (1) and gathered in one place as shown in Figure 1. Then, as shown in Fig. 2, this large number of circular bars (3) is divided into 4 parts, and between them, beam 2) or beam 2 is separated.
), and then place the bracket that connects the two beams (2) or cylindrical beams (2) at a predetermined position on the mountain face of the steel frame ii':? It is fixed by 9th tangent etc. In the example, a number of annular 6131 t
All cases in which the image is divided into two upper and lower groups such as C3a) and (3b) are shown below. The number of divisions is determined according to the number of floors to be constructed, and the number of annular bars (3) fitted in advance to the iron *+1) is also determined according to the construction W1.

The shape of the annular muscle 31 can be formed into a rectangular frame shape or a perfect circular shape, as shown in FIGS. 4 and 5, but the shape is not limited to this shape.

A large number of steel frames assembled in this way, that is, assembled in the manner shown in Figure 2, were delivered to the site.
: Place the adjacent steel frames (-) in the left and right direction of E3 Me 1. Then, the beams 12° are connected to each other at the center between the left and right steel frames +ll and Il+, or the beam i21 is inserted between the brackets for beam connection to connect the entire steel frame [,'I! To dig. .

In addition, during the erection of the steel frame (1) in the above-mentioned work area or the construction of the joint between the steel frame (1) and the steel frame (1), a large number of annular reinforcements (13) separated into sets are It is a good idea to temporarily tie it with a rope or the like to prevent hyperactivity, and then insert, for example, four wooden vertical irons (41) into the many annular muscles (3) as shown in Figure 3. After that, make the seven rings 1I75+31 into upper and lower negated pitches respectively n'

A steel reinforced conocrete column was constructed by pouring the W frame (concrete 16 inside 51) into the pear R+1511 set as shown by the chain line in FIG. 5.

In addition, as shown by the chain line in Fig. 2, the same annular muscle (1)k as the annular muscle 13) is also fitted on the outer periphery of the beam 1IiJ and 2j, and this After erecting 6 iron "1-j'・1) adjacent to

They may be coupled to f1η, respectively.1. In this way, the steel frame for use is not only for one space, but also for two beams.
), and the same work as in the case of one on the steel frame may be performed on the beam and the beam.

[The young fruits of invention]

In this way, ten:
By fitting a predetermined number of annular reinforcements into the beam or beam joint, which is placed in the direction of the beam, it is possible to create a center joint type. Even in the case of the planknod type, it is a j upper reinforcement or stop of a circular reinforcement whose contact parts are welded to each other in advance to form a single wooden ring, and it is easy to assemble with vertical reinforcement at the construction site. This is a very unique construction method, as it can create a structure with excellent strength.
