Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reinforcement arrangement method for a reinforced concrete structure, and more particularly, to a reinforcement arrangement method for a reinforced concrete structure in which a large number of reinforcing bars are arranged based on a reinforcement drawing.

(Conventional technology) Generally, when constructing a building with a reinforced concrete structure, first, after the foundation work is completed, a large number of hoop reinforcements are placed on the column main reinforcements to be erected at the column positions, and wall reinforcements are placed to construct the walls. ,
Formwork for the pillars and walls is provided, and formwork for the beams and floor are subsequently installed, and after the formwork work is completed, reinforcement is placed for the beams and the floor, and concrete is poured.

By the way, when placing hoop reinforcement on the main reinforcement of the column, when placing reinforcement on the main reinforcement of the column, or on walls and floors, check the reinforcement arrangement diagram on reference members near the walls and floors. Mark the reinforcement position of each reinforcing bar according to It was fastened with a binding wire.

(Problem to be solved by the invention) However, it is necessary to mark a large number of reinforcing bar placement positions in places with poor footing, and the accuracy of marking varies depending on the skill of the person making the marks. In the case of structures that stand up vertically, such as walls, it is necessary to support the heavy reinforcing bars by hand, match them to the mark positions, and tie up the intersecting reinforcing bars using wire binding lines, which requires an extremely large number of binding points. In addition to requiring a large amount of time and manpower to perform the tying work, there were problems in that the tying work could damage the wrists, and the pressure of the concrete loosened the tying points, making it difficult to improve construction accuracy.

Therefore, the present invention aims to provide a method for arranging reinforcing bars for concrete structures that can reduce the time and manpower required to place reinforcing bars in a regular schedule, and also improve construction accuracy even by people with low skill. be.

(Means for Solving the Problems) The present invention provides a plurality of reinforcing bar holding portions (82
)...(84)...(86)... Reinforcement members (8a to 8
e), and a plurality of reinforcement parts tt (8a to 8e) are arranged at predetermined intervals in a direction perpendicular to the reinforcement direction, and each of the reinforcement members (8a to 8e) (8a ~8e

While holding the reinforcing bars (5a to 5e)..., the iron 1i7i (
5a to 5e)... at predetermined intervals to the reinforcing bars (5a to 5e) arranged orthogonally to the reinforcing bars (5a to 5e),
Moreover, the reinforcement is arranged in a certain direction.

It is something.

(Function) The reinforcement members (8a to 8e) are linear and rigid, and have a plurality of reinforcing bar holding portions (82) at intervals according to the reinforcement pitch.
) ...(82) ...(84) ...(86) ...(86) A plurality of the reinforcing bar holding members (82)...(84)...(8) are attached at intervals.
6) Place the reinforcing bars (5a to
5e), the pitch of the reinforcing bars (5a to 5e) in the longitudinal direction of the reinforcement members (8a to 8e) naturally becomes a predetermined reinforcement pitch, and the reinforcing bars (5a to 5e) Since they are held by the holding parts (82), (84), and (86), there is no need to tighten the reinforcing bars (5a to 5e) with wire binding lines.

There is no need for it.

(Example) The method of the present invention will be described in detail below based on FIGS. 1 to 5.

Figure 1 shows reinforced concrete columns (1), walls (2), and floors (
3) is an explanatory diagram of the reinforcement arrangement when constructing, where (4)... is the column main reinforcement rising above the foundation, (5a)... is the main reinforcement (
4) These are reinforcing bars called hoop reinforcements, which are arranged so that the main reinforcing bars (4) do not open from each other, and are arranged at predetermined intervals in the length direction of the main reinforcing bars (4). To arrange reinforcement in this way, first, as shown in Figure 2, one side of the straight angle material is punched out at a reinforcement pitch based on the reinforcement diagram, and a large number of locking pieces (81) are provided. , this locking piece (81) is bent outward to form an oval shape to form a reinforcing member (8a) in which the bottom of the locking piece (81) serves as reinforcing bar holding II (82)... Then, two reinforcement members (8a) are erected in the same direction as the main reinforcements (4), that is, in a direction orthogonal to the hoop reinforcement direction, and a predetermined distance is set between the reinforcement members (8a) (8a). It's about keeping an interval.

In other words, as shown in the column (1) part of Fig. 1, the column main reinforcement (4
)... In the rectangular cross section of the column (1) formed by..., the two reinforcement members (8a) are placed at positions corresponding to two adjacent sides.
(8a) is placed.

Then, the positions of the reinforcement members (8a) (8a) are adjusted so that the reinforcing bar holding portions (82) of each reinforcement member (8a) are located at the reinforcement positions of the reinforcing bars (5a) that become hoop reinforcements. While adjusting and placing the reinforcing bars (5a) on the foundation and holding the reinforcing bars (5a) in each of the reinforcing bar holding parts (82), bend the outside of the main reinforcing bars (4) so as to wrap them around the column (1). The main reinforcement located at the corner (
In 4), both ends of the reinforcing bars (5a) are further bent inward of the column (1).

Therefore, as in the past, the reinforcing bars (5a) are placed in line with the mark position.
It is only necessary to support the weight of the reinforcing bars (5a) on the reinforcing bar holding part (82) and bending the reinforcing bars (5a) without having to support them by hand. Therefore, the reinforcing bars can be arranged easily and in a short time. The reinforcing bars (5a) can be attached to the reinforcing bar holding part (82)
), the reinforcement will automatically be placed at intervals in the column (1) direction according to the reinforcement drawing.

Next, for the wall (2) reinforcement, first, the reinforcement members (8b) that hold the horizontal reinforcing bars (5b) are placed vertically along the upright direction of the wall (2) and at a predetermined interval. Each reinforcing bar holding portion (8b) provided on each reinforcing member (8b) is
2) The horizontal reinforcing bars (5b) are held one after another, like hanging a pole on a clothesline. On the other hand, in order to hold the reinforcing bars (5C) in the vertical direction, approximately U-shaped notches (83) are placed in the elongated plate at intervals according to the reinforcement pitch in the length direction, as shown in Fig. 3. Reinforcement members arranged in multiple rows (
8C), and the bottom of the cutout (83) serves as a reinforcing bar holding portion (84). Then, this plate-shaped reinforcing member (8C) is welded perpendicularly to the reinforcing member (8b) that supports the horizontal reinforcing bars (5b). At this time, as shown in FIG. 5, the bottom of the notch (83) is connected to the notch (83) by the horizontal reinforcing bar (5b) when looking at the reinforcing member (8C) in the form of a horizontal rod from above.
83) from the open side.

After doing this, the vertical reinforcing bars (5C) are held at the bottom of the notch (83), that is, the reinforcing bar holding portion (84). Thus, horizontal and vertical reinforcing bars (
5b) (5c) to each of the reinforcing bar holding parts (82)...(84)
By holding the reinforcing bars (5a)...(5c) at intervals according to the reinforcement pitch in each direction, horizontally and vertically.
... will be reinforced, and moreover, the intersecting reinforcing bars (5b
) (5c) can be reinforced without tightening with binding wires.

Furthermore, in the case of floor (3) reinforcement, as shown in Figure 4, approximately U-shaped notches (85) are made on one side of the angle material at intervals corresponding to the reinforcement pitch in the length direction. A large number of reinforcing members (8d) and (8e) are arranged in rows, and the bottom of the cutout (85) serves as a reinforcing bar holding portion (86).

Therefore, the reinforcement members (8d) and (8e) are arranged in two directions, vertically and horizontally, so that the open end of the notch (85) is located upward, and the reinforcing bars are held. Part (8
6) are positioned at each reinforcement position in the reinforcement diagram, and then sequentially attach the reinforcing bars (5d)...(5e) to each of the reinforcing bar holding parts (86)...
By holding the reinforcing bars (5e) (5d), it is possible to easily arrange the reinforcing bars (5e) (5d) in the vertical and horizontal directions at intervals according to the reinforcement drawing, and the reinforcing bars (5d) (5e) (8b)
While being supported at the bottom of the reinforcing bars (5d) (5e), the horizontal movement of the reinforcing bars (5d) (5e) is restrained.
There is no need to tighten the intersection e) with a binding wire.

In addition, punch out one side of the angle material and make an L-shaped locking piece (81
) to form the reinforcement members (8a) and (8b), channel materials may be used, and the cross-sectional shape is not limited to an angle.

In addition, when the locking piece (81) holds the reinforcing bars (5a) and (5b), the tip of the locking piece (81) is hit with a hammer or the like to hold the reinforcing bars (5a) and (5b). By attaching them, the reinforcing bars (Sa) and (5b) can be held even more reliably. Also, the locking piece (81) is
zz＼Can be installed side by side. In addition, when arranging reinforcing bars (5a) as hoop bars to the main bar (4) of the column (1), a large number of hoop bars are assembled to the reinforcement member (8a) to form an hB shape, and then this Alternatively, it may be dropped from above the column main reinforcement (4) so as to surround the main reinforcement (4). In this way, work at heights can be reduced and work can be carried out safely. Furthermore, in the case of wall (2) reinforcement, the order of reinforcing bars (5c) and (5b) in the vertical and horizontal directions may be reversed, or the reinforcing members arranged in the horizontal and vertical directions may be reversed. After forming a framework with (8c) and (8b) and positioning this framework at the position of the wall (2), the reinforcing bar holding part (82) of each reinforcement member (8b) and (8c)... and (8
4) may hold the reinforcing bars (5b) and (5c).

(Effects of the Invention) As described above, according to the present invention, a plurality of reinforcing bar holding portions (82)...(84) are provided at intervals according to the reinforcement pinch in the length direction of a linear member of a predetermined length to provide rigidity. ...(86)... are formed to form reinforcement members (8a to 8e), and these reinforcement members (8a to 8e) are formed.
8e) are arranged at predetermined intervals in a direction perpendicular to the reinforcement direction, and each of the reinforcement members (8a to 8e)
(8a to 8e) each of the holding parts (82)...(84)...(
86) Hold the reinforcing bars (5a to 5e)... to the reinforcing bars (5a to 5e) arranged in a direction perpendicular to the reinforcing bars (5a to 5e). Since the reinforcement is arranged at predetermined intervals and in a fixed direction, there is no need to mark many reinforcement positions in places with poor footing as in the past, so the accuracy of the reinforcement position depends on the skill of the person marking it. There is no variation, and when arranging horizontal reinforcing bars in vertical columns and walls, there is no need to manually support the reinforcing bars according to the mark position and tie them to the vertical reinforcing bars with binding wires. Therefore, compared to conventional reinforcement work, reinforcement can be placed in a shorter time and with fewer people without injuring the wrists.
Construction accuracy is improved because there is no displacement of reinforcing bars due to loosening of binding wires during concrete pouring.
