Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening reinforcing assembly rebar unit used to reinforce the surroundings of openings such as ventilation openings and inspection openings formed in a basic rebar frame for a house.

[0002]

2. Description of the Related Art A cloth foundation made of cast-in-place reinforced concrete is used as a foundation for a house. Cloth foundation
It has a base portion and a rising portion rising vertically from the base portion, and these are arranged continuously along the lower side of the outer peripheral wall, the inner partition wall, and the like. Therefore, in order to form a ventilation port, an inspection port, etc., it is necessary to open an opening for ventilation or inspection at the rising portion. When the opening is formed, the strength of that portion is reduced, and therefore it is necessary to arrange reinforcing bars or the like for reinforcement.

Conventionally, a rebar worker cuts a portion of the rebar frame where the opening is located, and around the formed opening,
Reinforcing reinforcing bars are arranged vertically, horizontally and diagonally, and are connected by a binding bar or the like.

[0004]

In order to save labor and shorten the construction period of foundation bar arrangement work, in recent years, a factory-produced rebar frame for a cloth foundation is brought into a construction site and these are installed. A method of arranging the cloth foundation by arranging them at specified positions and connecting them to each other has been adopted.
According to such a bar arrangement method, it is possible to perform an accurate bar arrangement of the basic rebar by a simple operation without requiring skill.

An object of the present invention is to further improve the efficiency of the work for arranging a cloth foundation using such a factory-produced rebar frame.

[0006]

For that purpose, it is necessary that the reinforcement bar around the opening for ventilation and inspection formed in the rising portion of the cloth foundation can be accurately arranged by a simple operation. There is. In the present invention, focusing on this point,
The reinforcing assembly rebar unit having the following structure is manufactured in advance in a factory, and the reinforcing bar around the opening can be completed only by arranging the reinforcing bar unit around the formed opening at the construction site.

That is, the opening reinforcing reinforcing bar unit used to reinforce the periphery of openings such as ventilation openings and inspection openings formed in the rising reinforcing bar frame arranged at the rising part of the reinforcing bar for the cloth foundation of the present invention is horizontal. A lower rebar extending to
The lower end is spot-welded at both sides of the lower rebar and the left rebar and right rebar that extend vertically upward and vertically, and the lower rebar is lower-end spot-welded and the left rebar. Crossing and extending diagonally upward, the left diagonal reinforcing bar that is spot welded to the left reinforcing bar, and the lower end is spot-welded to the lower reinforcing bar and the right reinforcing bar intersects and extends obliquely upward, the right reinforcing bar. With a right diagonal reinforcing bar that is spot-welded to, so that the lower reinforcing bar, the left reinforcing bar and the right reinforcing bar are located on the lower side and both sides of the opening opened in the rising reinforcing bar frame, respectively. It is characterized by being attached and used.

The periphery of the opening can be reinforced by a simple work of simply attaching the opening reinforcing reinforcing bar unit having this structure to the periphery of the opening opened in the rising reinforcing bar frame arranged at the rising portion of the cloth foundation. . Therefore, it does not require special skill, and since the unit is a standard product manufactured at the factory, the reinforcement can always be performed accurately.

Here, the portion where the opening is formed may be located near the corner portion of the cloth foundation. In this case, there is often no room to arrange the diagonal reinforcing bars on the side near the corner. In this case, an opening reinforcing reinforcing bar unit having the following configuration may be adopted. That is, the right diagonal rebar or the left diagonal rebar near the corner is prepared as a separate item. The diagonal reinforcing bar, which is prepared separately, has a shape in which the upper half part is bent at a right angle so that it can be arranged along the corner part. If the diagonal reinforcing bars of this shape are used, the diagonal reinforcing bars can be arranged even when the opening is located near the corner portion, so that sufficient reinforcement can be realized.

On the other hand, when an opening is formed in the portion of the cloth foundation having an extremely short span, there may be no room for arranging the diagonal reinforcing bars on either side. In this case, an opening reinforcing reinforcing bar unit having the following configuration may be adopted. That is, the left and right diagonal reinforcing bars are prepared separately. These diagonal rebars have a shape in which the upper half portion is bent at a right angle. If the diagonal reinforcing bars of this shape are used, the diagonal reinforcing bars can be arranged on both sides of the opening formed in the portion of the cloth foundation having an extremely short span, so that sufficient reinforcement can be realized.

On the other hand, the present invention relates to a reinforcing bar unit for a cloth foundation which is reinforced as described above, and the unit is a base reinforcing bar frame arranged at the base portion and the rising portion of the cloth foundation reinforcing bar. And a rising rebar frame, and these base rebar frame and standing rebar frame are
Each of the vertical rebars extending in parallel to the longitudinal direction is composed of horizontal rebars joined to these rebars at regular intervals, and one end of the vertical rebars has a constant length from the horizontal rebars. It is characterized by protruding only a little.
When the unit of this structure is used, when the units are connected to each other in an L shape or a T shape, only the portions of the reinforcing bars located inside are overlapped. Therefore, there is an advantage that leveling of both units becomes easy.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a reinforcing bar frame for a cloth foundation to which the present invention can be applied. As shown in this figure, a reinforcing bar frame (unit) 1 for a cloth foundation includes a base reinforcing bar frame 2 arranged in a base part and a rising reinforcing bar frame 3 arranged in a rising part standing upright from the center. It consists of

On one end side of the reinforcing bar frame 1, the ribs 33a of the rising reinforcing bar frame 3 and the horizontal bars 21a of the base reinforcing bar frame 2 are attached. However, on the opposite end, the stirrup bar 3
Main bars 31 and 34 project upward and downward by a constant length L from 3b. Further, the base reinforcement frame 2 also has left and right reinforcing bars 22 and 23 protruding from the horizontal reinforcement 21b by the same length L. These protrusion amounts are, for example, the same as the pitch of the stirrups and the horizontal streaks.

By arranging the reinforcing bar frames 1 having this structure according to the foundation plan view and connecting the adjacent reinforcing bar frames to each other through the joint bar, the reinforcing work of the cloth foundation can be performed.

When the reinforcing bar frame having this structure is arranged, such an opening part is formed in the reinforcing bar frame by cutting the reinforcing bar at the part where the opening for inspection or ventilation is located. For example, the rising rebar frame 3 at the portion where the opening is located
The main muscle upper end muscle 31 and the abdominal muscle 32 are cut by the required width. Further, the stirrup bars 33 extending vertically at regular intervals are also cut by the required number.

FIGS. 2A and 2B show a reinforcing reinforcing bar unit for opening which is a first embodiment of the present invention. This reinforcing reinforcing bar unit for opening 10 has a lower reinforcing bar 11 extending horizontally and lower ends 12a and 13a spot-welded at positions on both sides of the lower reinforcing bar 11 and vertically extending upward. The left side reinforcing bar 12 and the right side reinforcing bar 13 and the lower side reinforcing bar 11 are spot-welded on the lower end side, cross the left side reinforcing bar 12 and extend obliquely upward at an angle of 45 degrees, and the left side reinforcing bar 12 is spot-welded on the left side. The diagonal reinforcing bar 14 and the lower diagonal side of the lower reinforcing bar 11 are spot-welded, and the right diagonal reinforcing bar 15 is spot-welded to the right-side reinforcing bar 13 by crossing the right-side reinforcing bar 13 and extending obliquely upward at an angle of 45 degrees. have.

The lower rebar 11 has five auxiliary rebars 111 attached at regular intervals in the central portion thereof and extends vertically downward, and the lower ends of these rebars 11 are transverse rebars 11.
2 is spot welded. Left and right rebar 1
Reference numerals 2 and 13 have an inverted L shape, which includes vertical portions 121 and 131 and horizontal portions 122 and 132 that are bent and extend at right angles from the upper ends thereof in a direction that spreads to the left and right.

On the other hand, the left diagonal reinforcing bar 14 has an inclined portion 141.
And a horizontal portion 142 continuous to the lower end thereof. The horizontal portion 142 at the lower end is welded to the horizontal reinforcing bar 112. The inclined portion 141 extends across the vertical portions 121 of the lower reinforcing bar 11 and the left reinforcing bar 12, and is spot-welded at the intersecting portions. The upper end of the inclined portion 141 has a horizontal portion 122 of the left reinforcing bar 12.
Spot welded to the tip of. The right diagonal reinforcing bar 15 is
It has a left-right symmetrical shape with the left diagonal reinforcing bar 14. That is, the inclined portion 151 and the horizontal portion 152 continuous to the lower end thereof are provided. The horizontal portion 152 at the lower end is welded to the horizontal reinforcing bar 112. The inclined portion 151 extends so as to intersect the vertical portions 131 of the lower reinforcing bar 11 and the right reinforcing bar 13 and is spot-welded at the intersecting portions. The upper end of the inclined portion 151 is the right reinforcing bar 1
It is spot-welded to the tip of the horizontal portion 132 of No. 3.

FIG. 2C shows an example of reinforcing the opening using the reinforcing bar unit 10 for reinforcing the opening having this structure. As shown in this figure, the abdominal muscles 32 of the standing-up reinforcing bar frame 3 at the portion where the opening is located are cut by the required width. Further, the ribs 33 extending vertically at a constant interval are also cut by the required number (three in the illustrated example). In the figure, the abdominal muscles and stirrups that have been cut are indicated by broken lines. In this way, the portion corresponding to the opening is formed.

With respect to the opening portion thus formed,
An opening reinforcing reinforcing bar unit 10 is attached. That is, the lower reinforcing bar 11, the left reinforcing bar 12, and the right reinforcing bar 13 are attached to the rising reinforcing bar frame so that the lower reinforcing bar 11, the left reinforcing bar 12, and the right reinforcing bar 13 are located below and on both sides of the opening 5 opened in the rising reinforcing bar frame. The attachment and the fixing are performed using, for example, a binding muscle. As described above, if the reinforcing bar unit 10 for opening reinforcement of the present example is simply attached and fixed to the portion of the opening 5, the reinforcing bar arrangement around the opening is completed. Therefore, the reinforcing bar arrangement work can be performed extremely easily as compared with the conventional reinforcing bar reinforcement work. Moreover, since the reinforcing bar unit 10 for opening reinforcement is manufactured at the factory, the reinforcing bar unit 10 is reinforced by using a reinforcing bar having a small diameter, so that there is no problem such as insufficient reinforcement.

Next, FIGS. 3A and 3B show an opening reinforcing reinforcing bar unit according to a second embodiment of the present invention. The reinforcing bar unit 20 for reinforcement shown in this figure is used when there is no room for arranging diagonal reinforcing bars because the openings are formed in the vicinity of the corners.

Since the basic structure of the reinforcing bar unit 20 is the same as that of the reinforcing bar unit 10 described above,
Corresponding parts are designated by the same reference numerals. The different points are that the left diagonal reinforcing bar 14 is not integrally attached, and that the upper part of the left reinforcing bar 12 is bent in a hook shape instead of the horizontal part 122 and a hook-shaped part 123 whose tip side hangs downward. It is the point that is formed.

When this rebar frame unit 20 is used, a diagonal rebar 24 having a shape as shown in FIG. 3 (C) is used. The diagonal reinforcing bar 24 includes an inclined portion 241 and a horizontal portion 242 that is continuous with the inclined portion 241.
On the upper side of the inclined portion 241, the horizontal portion 2
43 are formed. However, this horizontal part 243
Is bent in a direction orthogonal to the plane in which the inclined portion 241 and the horizontal portion 242 are located.

FIG. 3D shows an example of opening reinforcement by the reinforcing bar unit 20 for opening reinforcement having the above structure. As shown in the figure, the opening 5 is located on the side of the reinforcing bar frame 3A near the corners of the rising reinforcing bar frames 3A and 3B forming the L-shaped corners. Therefore, FIG.
Even if the reinforcing reinforcing bar unit 10 having the shape shown in (A) is to be attached, there is no room for disposing the left diagonal reinforcing bar 14 having an integral structure. However, the reinforcing rebar unit 20 of this example is
The left diagonal reinforcing bar 14 is not integrally attached. Therefore, it can be attached around the opening 5 as shown in the figure.

Since the left diagonal reinforcing bar 14 is omitted here, reinforcement on the left side of the opening 5 is insufficient. But,
In this example, the left diagonal reinforcing bars 24 having the shape shown in FIG. 3C are used in pairs. This left diagonal rebar 24
The upper end side of the inclined portion is bent at a right angle and extends horizontally. Therefore, the horizontal portion 243 may be arranged so as to extend along the side surface of the reinforcing bar frame 3B. With this arrangement, the left portion of the opening 5 is also reinforced because the inclined portion 241 of the left diagonal reinforcing bar 24 is located.

As for the position of the opening portion 5, conversely,
It may be near the right corner. In this case, as shown in FIG. 4, it is sufficient to use a unit 30 having a structure symmetrical with the reinforcing reinforcing bar unit 20 described above. Also,
A right diagonal reinforcing bar having a symmetrical shape with the above left diagonal reinforcing bar 24 may be used.

Next, FIGS. 5A and 5B show an example of an opening reinforcing reinforcing bar unit 50 used when there is no room to reinforce the diagonal reinforcing bars on the left and right of the opening portion 5. The reinforcing bar unit 50 includes a left reinforcing bar 12 and a right reinforcing bar 13.
, The hook-shaped portions 123, 133 are formed on the upper side thereof, and the left and right diagonal reinforcing bars 14, 15 are omitted. The other structure is the same as each of the above examples.

This rebar unit 50 is used together with the left diagonal rebar 24 and the right diagonal rebar 54 having the shapes shown in FIGS. 5 (C) and 5 (D). The right diagonal reinforcing bar 54 has a shape symmetrical with the left diagonal reinforcing bar, and includes an inclined portion 541, a lower horizontal portion 542, and an upper horizontal portion 543 bent in a direction orthogonal to each other.

As shown in FIG. 5 (E), in the case where the reinforcing bar frames 3B and 3C are connected to both sides of the basic reinforcing bar frame 3A having an extremely short span in a direction orthogonal to each other, the basic reinforcing bar frame 3A is used. When the opening portion 5 is formed in, the left and right diagonal reinforcing bars cannot be arranged because there is almost no margin on the left and right. However, when the left diagonal reinforcing bar 24 and the right diagonal reinforcing bar 54 as in this example are used, the diagonal reinforcing bars 24, 5 are arranged along the reinforcing bar frames 3B and 3C which are orthogonal to the reinforcing bar frame 3A, respectively.
4 can be placed. Therefore, even in such a case, diagonal reinforcing bars can be arranged on the left and right to sufficiently reinforce the opening portion.

Next, FIG. 6 shows another example of opening reinforcement using the reinforcing bar units 20 and 30 for opening reinforcement shown in FIGS. 3 and 4. As shown in this figure, when the basic reinforcing bar frame 3C is coupled to the basic reinforcing bar frame 3A in a T shape, the opening parts 5A and 5B may be formed on both sides of the basic reinforcing bar frame 3C, respectively. . In this case, the reinforcing bar units 20 and 30 may be attached in a bilaterally symmetrical state. However, in this case, since there is no room in the central portion, the left diagonal reinforcing bar of one reinforcing bar unit 20 and the right diagonal reinforcing bar of the other reinforcing bar unit 30 cannot be arranged. In this example, the diagonal reinforcing bars 65 having the shape shown in FIG. 6 (B) are used. The diagonal reinforcing bar 65 is formed by bending the center into a mountain shape and forming inclined portions 651 and 652 on the left and right. Horizontal portions 653 and 654 are formed continuously from the lower ends of the inclined portions 651 and 652, respectively.

As shown in FIG. 6 (A), the diagonal reinforcing bars 65 of this shape are arranged between the reinforcing bar units 20 and 30 so as to be symmetrically positioned. As a result, the left and right inclined portions 651 and 652 reinforce the diagonal reinforcing bars. Therefore, the reinforcement of the opening in such a portion is sufficient.

[0033]

As described above, according to the present invention, the reinforcing bars for reinforcing the opening are unitized in advance,
By attaching this to the opening, the opening is reinforced. Therefore, according to the present invention, since it is not necessary to attach a large number of reinforcing bars vertically, horizontally, and diagonally to realize opening reinforcement, it is possible to arrange reinforcing bars in a short time without requiring skill. You can Also, since the unit is manufactured at the factory, there is no possibility that the diameter of the reinforcing bar for reinforcement will be too small for sufficient reinforcement.
A proper reinforcement bar can always be realized.
