BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar unit for a building foundation used for construction of a residential cloth foundation.

[0002]

2. Description of the Related Art Conventionally, as a frame for constructing a wooden house foundation,
The configuration shown in FIG. 3 is known (Jitsuko Sho 60-3).
3158). The foundation building muscle frame of FIG. 3 is formed by welding both ends of a plurality of lateral muscles a and b extending in parallel to each other and welding both end portions of a plurality of transverse muscles c whose central portions are curved upward and downward. And a lower end of the horizontal bar c, a shaft bar e parallel to both the bar lines a and b is rotatably inserted, and the lower ends of a plurality of vertical bars f are welded to the shaft bar e. The rising streaks i are formed by welding the streaks g and h extending parallel to the both-side streaks a and b to the upper end and the center of the vertical streaks f, respectively. The muscle frame of FIG. 3 can be folded by tilting the rising muscle i around the axis muscle e, which is convenient for transportation, and the standing muscle i can be rotated to be vertical at the site. Therefore, on-site work becomes easy.

[0003]

However, the above-mentioned foundation building frame of FIG. 3 has the following drawbacks. In the foundation work, depending on the situation of the construction site, it may be necessary to shift the standing muscle i in the longitudinal direction of the horizontal bar c, but in the frame of FIG. 3, the position of the axial bar e is the horizontal bar c. Since it is fixed to the central portion, the rising muscle i cannot be displaced along the lateral muscle c, and therefore construction may be difficult depending on the situation of the site.

In the foundation work, it may be necessary to carry out the construction by appropriately combining the base muscles and the standing muscles of various sizes on site, but the muscle frame in FIG. 3 has the base muscles d and the standing muscles i. Since it is not possible to release the connection, it is impossible to change the specifications by exchanging the base muscles d and the rising muscles i with other ones, and similarly, the construction may be difficult depending on the situation of the site. there were.

[0005] Muscle frame of FIG. 3, to produce a finished product advance factory but is intended to transport in the folded state, will be inevitably bulky because the base muscle d and the rising muscles i is connected, It may be inconvenient for transportation. In such a case, it is desirable to transport the base muscle d by removing the rising muscle i, but since the muscle frame of FIG. 3 cannot release the connection between the base muscle d and the rising muscle i, I couldn't.

The muscle frame of FIG. 3 is constructed at the site with the rising muscle i vertical, but the muscle frame of FIG. 3 only has the axial muscle e inserted below and above the lateral muscle c. The axis muscle e is easily rotated, and therefore, when the rising muscle i is raised, the gravity causes the axis muscle e to rotate and the rising muscle i is easily collapsed. Therefore, it is necessary to maintain the vertical state of the standing muscle i by using an auxiliary muscle or the like, which makes the on-site work troublesome.

The present invention has been made in view of the above circumstances, and it is possible to easily change the position of the standing muscles and replace the base muscles and the standing muscles on site, and further, to connect the base muscles and the standing muscles. An object of the present invention is to provide a reinforcing bar unit for a building foundation, which can be transported in a separated state or in a separated state, and can maintain a vertical state of a standing muscle without using auxiliary muscles or the like.

[0008]

In order to achieve the above-mentioned object, the present invention fixes a plurality of second transverse muscles orthogonal to the first transverse muscles between a plurality of first transverse muscles provided in parallel with each other. And a standing muscle formed by fixing a plurality of second vertical muscles orthogonal to the first vertical muscles between a plurality of first vertical muscles provided in parallel with each other, and a U-shaped bend Forming a curved portion for inserting a transverse line in the middle portion of the wire, and providing a hooking portion having a locking bending portion at one end of the wire, and extending the other end of the wire ahead of the hooking portion, For the insertion of the horizontal muscle, insert the lowermost first vertical muscle of the standing muscle into the U-shaped bend with the lowermost first vertical muscle of the standing muscle being arranged orthogonally on the second horizontal muscle of the base muscle. Insert the second transverse muscle of the base muscle into the curved portion and hook the hooking portion to the first vertical muscle at the bottom of the standing muscle. In both cases, when the other end of the wire is inserted into the locking bent portion, the first vertical line is pressed against the second horizontal line, and the first vertical line is rotated in the circumferential direction. A reinforcing bar unit for a building foundation, comprising a detachable clip that connects a horizontal bar and a first vertical bar.

[0009]

In the present invention, since the detachable clip is used to connect the base muscle and the standing muscle, the standing muscle is connected to the base muscle by once removing the clip and disconnecting the connection between the base muscle and the standing muscle. In addition to being able to be reattached to an arbitrary position, the specifications can be changed by exchanging the base muscles and the standing muscles, and the base muscles and the standing muscles can be separated for transportation.

Further, in the present invention, since the first vertical line is pressed against the second horizontal line by using a clip having a specific shape, the first vertical line is pressed against the second horizontal line and the first vertical line is pressed. The muscles are hard to turn. Therefore, when the rising muscle is raised, the gravity prevents the first vertical muscle from turning and the rising muscle from falling down, and the vertical state of the rising muscle is maintained without using auxiliary muscles or the like.

[0011]

EXAMPLES The present invention will now be specifically described with reference to examples, but the present invention is not limited to the following examples.
FIG. 1 shows an assembled state of a reinforcing bar unit for a building foundation according to an embodiment of the present invention. The unit 1 is formed by connecting a base bar 2 and a standing bar 3 with a clip 4.

The base muscle 2 is provided with a pair of first lateral muscles 5 and 5 arranged in parallel at a predetermined distance from each other.
Both ends of the three second horizontal bars 6, 6, 6 which are arranged at a predetermined interval orthogonal to 5 are fixed by welding. The rising streaks 3 are arranged on the three first vertical streaks 7, 7, 7 which are arranged in parallel at a predetermined distance from each other, and are arranged at predetermined intervals perpendicular to the first vertical streaks 7, 7, 7. Both end portions and the central portion of the three second vertical bars 8, 8 and 8 are fixed by welding. The horizontal bars 5 and 6 and the vertical bars 7 and 8 are deformed iron bars having a circular cross section having a large number of ring-shaped projections on the circumferential surface.

The clip 4 has a wire 9 as shown in FIG.
Is bent into a U-shape, and a bending portion 1 for inserting a transverse muscle is provided at an intermediate portion thereof.
0 and 10 are formed, and one end of the wire 9 is engaged with the tip end and bent portion 1
1 is provided, and the other end of the wire 9 is extended beyond the hook portion 12. The hook portion 12 is formed by bending one end of the wire 9 inward in a substantially right angle direction and bending or bending the bent portion into a substantially semicircular shape so that the first vertical line 7 can be inserted therein. Has become. Further, the hooking bent portion 11 is the hooking portion 1
It is formed by folding the tip of the wire 2 upward, and the other end of the wire 9 can be inserted therein.

When the base muscles 2 and the standing muscles 3 are connected by the clip 4, the lowermost first vertical muscles 7 of the standing muscles 3 are arranged orthogonally on the three second horizontal muscles 6 of the base muscle 2. rear,
The other end of the wire 9 and the hook portion 12 are pulled to both sides to open the clip 4, and then the first vertical bar 7 is inserted into the U-shaped bent part 13, and the second horizontal bar 6 is a curved part 10 for inserting a horizontal bar, 10
After passing the clip 4 under the second horizontal bar 6 so as to enter the inside, hook the hooking part 12 on the upper side of the first vertical bar 7, and insert the other end of the wire 9 into the locking bending part 11. Thus, the first vertical bar 7 is rotatably pressed against the second horizontal bar 6. In this case, the U-shaped bent portion 13 of the clip 4 is in pressure contact with the first vertical muscle 7, and the curved portion 1 for inserting the horizontal muscle 1
0 and 10 are in pressure contact with the second horizontal muscle 6, and the hook portion 12 is in pressure contact with the first vertical muscle 7. Further, the clip 4 can be removed by removing the other end of the wire 9 from the engaging bent portion 11 and removing the hooking portion 12 from the first vertical line 7.

The unit 1 of the present embodiment solves the problems 1 to 3 by using the detachable clip 4. That is, by removing the clip 4 and once disconnecting the connection between the base muscle 2 and the standing muscle 3, the position of the standing muscle 3 is changed, the specifications of the base muscle 2 and the standing muscle 3 are changed, and the base muscle 2 and the standing muscle 3 are changed. Separation and transportation can be performed very easily.

Further, the unit 1 of the present embodiment uses the clip 4 for connecting the second horizontal bar 6 and the first vertical bar 7 so that the first vertical bar 7 is pressed against the second horizontal bar 6. , The above problems are solved. That is, since the first vertical line 7 is strongly pressed against the second horizontal line 6 and the first vertical line 7 does not rotate easily, when the rising line 3 is raised, the first vertical line 7 rotates due to its gravity. Is prevented, and the vertical state of the standing muscle 3 is maintained without using auxiliary muscles or the like.

In this case, as described above, the clip 4 itself is also pressed against the first vertical line 7, which also makes it difficult for the first vertical line 7 to rotate. Therefore, in the unit 1 of this embodiment, the first vertical line 7 is less likely to rotate due to both the pressure contact force between the first vertical line 7 and the second horizontal line 6 and the pressure contact force between the clip 4 and the first vertical line 7. Therefore, the vertical state of the unit is held very firmly and does not fall over easily. Therefore,
The unit 1 of the present embodiment has a remarkable effect that the construction on the site is very simple. Further, in the unit 1 of the present embodiment, the deformed iron bar is used for the second horizontal bar 6 and the first vertical bar 7, so that when the base bar 2 and the standing bar 3 are connected, the clip 4 has a ring-shaped deformed bar. Caught in the protrusion,
Therefore, there is also an advantage that the base muscle 2 and the standing muscle 3 do not shift in the longitudinal direction or the lateral direction.

The base muscles, the standing muscles, and the clips are not limited to the shapes and structures of the above-mentioned embodiments. Further, other configurations may be variously modified without departing from the gist of the present invention.
