Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an assembled rebar for a building foundation used for construction of a residential cloth foundation or the like.

[Problems to be solved by conventional techniques and devices]

Conventionally, as an assembled reinforcing bar for constructing a wooden house foundation, one having a structure shown in FIG. 3 is known (Japanese Utility Model Publication No. 60-33158).

That is, the base reinforcing bar is constructed by welding both side parts of a plurality of lateral reinforcing bars a and b extending in parallel to each other and a plurality of lateral reinforcing bars c whose central portions are curved upward and downward. And the axial line e parallel to the both side lines a and b is rotatably inserted under and above the horizontal line c, and the lower ends of a plurality of vertical lines f are welded to the axial line e. Further, by welding the g and h extending parallel to the both a and b to the upper end and the central part of these vertical streaks f, respectively, the rising streaks i
Is configured.

The assembled reinforcing bar shown in FIG. 3 can be folded by tilting the rising bar i around the axis e, which is convenient for transportation, and at the site, the standing bar i can be simply rotated to make it vertical. Although good and thus facilitates field work, this rebar has the following drawbacks.

That is, in the foundation work, an assembled rebar in which the rising streak i is shifted in the length direction of the horizontal axis c may be required depending on the situation of the construction site, but the assembled rebar shown in FIG. Since the position of is fixed to the central portion of the horizontal streak c, the rising streak i cannot be displaced along the horizontal streak c, and therefore construction may be difficult depending on the situation of the site.

On the other hand, on the other hand, as an assembled rebar that allows the standing bar to be displaced along the horizontal bar at the site, it is also continuous to the lattice beam rebar with the upper end bar above the inner side of the continuous W-shaped stirrup bar and the lower end bar on the lower inside. The upper part of the W-shaped stirrup bar is arranged above and the lower part of the lattice base is fixed to the lower part, and the lower end bar of the lattice beam rebar is slidably incorporated into the inside of the lattice base bar. A lattice type in which the lattice beam rebar can be raised and lowered is known (Japanese Utility Model Publication No. 52-7053).

However, since the axial reinforcement (the lower end reinforcement of the beam reinforcement) is slidably arranged in the one described in this publication, the axial reinforcement may be displaced from the preset position during construction, which is inconvenient for construction. There are things.

The present invention has been made in view of the above circumstances, and can be manufactured in a state in which the axial muscle of the standing muscle is arranged at a desired position along the longitudinal direction of the lateral muscle of the base muscle, and at the time of construction, the axial muscle is It is intended to provide an assembled rebar that does not shift.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention comprises a pair of lateral muscles provided in parallel with each other and a plurality of lateral muscles whose both ends are alternately fixed to the upper side and the lower side of the both side muscles at predetermined intervals. And a plurality of vertical streaks whose bottom ends are fixed to the axial stirrues at predetermined intervals and which are parallel to the both side stirrers rotatably sandwiched between the upper and lower sides of the horizontal stirrup. In an assembled rebar consisting of a standing bar fixed to the upper end of a bar and having an upper bar parallel to the axial bar, a number of ring-shaped projections are formed on the circumferential surface of the rod-shaped main body as the reinforcing bar forming the lateral bar and the axial bar. While using a different diameter steel bar with a circular cross section
Provided is an assembled reinforcing bar for a building foundation, wherein a bar-shaped main bar having a diameter different from that of the above-mentioned two-sided bar is used as the bar with different diameter of the axial bar. In this case, the difference between the diameters of the axial and lateral muscles is not limited, but it is preferably 1 to 6 mm, particularly preferably 2 to 4 mm.

[Action]

In the present invention, the axial muscles are arranged between the upper and lower sides of the lateral muscles which are alternately fixed on the upper and lower sides of both lateral muscles, and the axial muscles are attached to the base muscles by sandwiching the axial muscles with the lateral muscles. The axial bar can be attached at a desired position along the longitudinal direction of the horizontal bar, and therefore the position of the axial bar is not fixed to the central part of the horizontal bar as in the assembled rebar of FIG. Can be used in the field. Also, by using different diameter steel bar with ring-shaped protrusions on the peripheral surface as the reinforcing bar that constitutes the horizontal bar and the axial bar, and by using a bar with a diameter larger than both side bars, the axial bar is placed between the upper and lower sides of the horizontal bar. When the pinch is clamped, the ring-shaped protrusions of the horizontal muscles and the ring-shaped protrusions of the axial muscles contact each other in an orthogonal state, and these protrusions are engaged with each other, and the axial muscles are Since it is strongly sandwiched between the upper and lower horizontal muscles, the axial muscles and the horizontal muscles do not deviate from each other after fabrication, and therefore the inconvenience that the position of the standing muscles deviates from the base muscles during the construction is surely prevented.

Next, the present invention will be described in detail with reference to examples, but the present invention is not limited to the following examples.

〔Example〕

FIG. 1 shows an assembled reinforcing bar for a building foundation according to an embodiment of the present invention. The assembled reinforcing bar 1 is composed of a base reinforcing bar 2 and a standing reinforcing bar 3 orthogonal to the base reinforcing bar 2.

Here, the base muscle 2 is a pair of side muscles 4, 4 arranged in parallel at a predetermined distance from each other, and a plurality of base muscles 2 are arranged at predetermined intervals orthogonal to the side muscles 4, 4. (Three in this embodiment)
The horizontal bars 5, 5, 5 are fixed by welding both ends thereof to the upper side and the lower side of the side bars 4, 4 alternately.

Further, the standing-up muscle 3 is formed on an axial muscle 6 parallel to the lateral muscles 4, 4 which is rotatably sandwiched between the upper and lower sides of the lateral muscles 5, 5, 5, at predetermined intervals perpendicular to the axial muscle 6. A plurality of (three in the present embodiment) vertical bars 7,7,7 arranged in the above are welded to the lower ends thereof, respectively, and the axial bar 6 is provided at the upper end and the middle part of these vertical bars 7,7,7. The upper end streak 8 and the intermediate streak 9 parallel to the above are respectively welded.

In this case, in the main assembly rebar 1, the horizontal bars 5, 5,
As the reinforcing bars constituting the shaft 5 and the axial bar 6, as shown in FIG. 2, a large number of ring-shaped projections are provided at predetermined intervals on the peripheral surface of the rod-shaped main body 10.
Different diameter steel bar with a circular cross-section with 11 is used (note that different diameter steel bars are also used as other reinforcing bars). Further, as the bar steel having different diameters of the axial reinforcement 6, the diameter of the rod-shaped main body 10 is larger than the diameter of the rod-shaped main body 10 of the above-mentioned both-side reinforcements 4 and 4 (in this embodiment, both-side reinforcements 4 and 4 are used). The diameter is 10 mm, while the diameter of the axial line 6 is 13 mm).

When manufacturing the assembled reinforcing bar 1 of the present embodiment, first, the standing bar 3 is produced, and further, the axial bar 6 of the standing bar 3 is connected to both side bars 4, 4.
The horizontal muscles 5,5,5 are arranged so that the axial muscle 6 is sandwiched between the upper and lower sides, and then the lateral muscles 5,5,5 are placed on both side portions of the lateral muscles.
It is welded to 4,4.

Therefore, the rebar 1 is assembled with the axial bar 6 and the horizontal bar 5,
By disposing the shafts 5 at appropriate positions along the length direction, the axial reinforcement 6 can be attached not only to the central portion of the transverse reinforcements 5, 5, 5 but also to desired positions such as the end portions. Further, after manufacturing, the horizontal bars 5, 5, 5 and the ring-shaped projections 11 of the axial bars 6 are engaged with each other in a state of being orthogonal to each other, and the axial bars 6 and 4 are caused by the difference in diameter between the lateral bars 4, 4 and the axial bars 6. Is strongly pinched by the horizontal muscles 5,5,5,
5,5,5 and the axial muscle 6 are not displaced from each other. Further, the assembled rebar 1 of the present embodiment has the advantage that it can be folded by tilting the rising bar 3 around the shaft bar 6 because the shaft bar 6 is rotatably provided, which is convenient for transportation. Also has.

In the above example, the diameter of the lateral muscle is 10 mm and the diameter of the axial muscle is 13 mm.
However, the diameters of the lateral muscles and the axial muscles are not limited to these. Further, although the base muscles and the standing muscles are formed in the lattice type in the above embodiment, they may be formed in other shapes such as lattice type, and other configurations may be variously changed without departing from the gist of the present invention. Absent.

[Effect of device]

As described above, the assembled reinforcing bar of the present invention can be mounted at a desired position along the longitudinal direction of the transverse bar during manufacturing, and therefore the assembled reinforcing bar can be arranged by arranging the axial bar at the center of the transverse bar. Can be made into a reverse T shape, or by arranging it at the end of the horizontal bar, the assembled rebar can be made into a reverse L shape, so it can be applied to construction sites in all situations, and after manufacturing the horizontal bar and axial bar The ring-shaped protrusions of the different-diameter steel bars that are configured are hooked in an orthogonal state, and the axial reinforcement is strongly sandwiched between the upper and lower sides of the horizontal reinforcement due to the difference in diameter between the two side reinforcements and the axial reinforcement. It is very convenient for construction because it does not shift from each other.
