Description

  The present invention relates to a reinforcing bar frame for a foundation, and more particularly to a reinforcing bar frame for a foundation constituted by combining reinforcing bars or the like that reinforce a concrete foundation of a building.

Conventionally, when building a building, a concrete is first placed to construct a foundation, and a foundation, a pillar, and the like are fixed on the constructed foundation.
When constructing a foundation in this way, in order to reinforce the foundation, reinforcement is often arranged in advance at the construction site of the foundation in advance. At this time, the reinforcing bars are cut according to the dimensions of the foundation, and the reinforcing bars of the foundation are constructed by assembling the reinforcing bars whose lengths are adjusted according to the dimensions at the locations where the foundation is to be constructed.

However, in order to prepare rebars of various lengths that match the dimensions of the foundation in this way, it is necessary to measure the size of the rebars one by one at the construction site and perform cutting work. It was complicated.
In addition, the construction contractor checks the length of the reinforcing bars necessary at the construction site, and cuts on the spot, resulting in a large amount of excess reinforcing bars (end materials) after cutting. There was also a problem of wasting it.

As one of solutions to such a problem related to cutting of reinforcing bars at a construction site, a frame for foundation construction disclosed in Patent Document 1 has been proposed.
In the frame for foundation construction disclosed in Patent Document 1, the reinforcing bars that are formed by crossing the reinforcing bars in the horizontal and vertical directions and the reinforcing bars that are formed by crossing the reinforcing bars in the vertical and horizontal directions vertically To form.
In this way, if you rise and rotate the rising streaks that stand up perpendicularly to the horizontal frame that is usually assembled in a horizontal plane, it overlaps with the same plane as the horizontal plane and becomes flat as a whole. It can be preliminarily combined at the factory, so that the rising bars are further compacted by sliding on the above-mentioned reinforcing bars on the horizontal plane and can be easily transported. In addition, at the construction site, the position of the rising bar can be easily adjusted without sliding the reinforcing bar as in the past by sliding the rising bar on the horizontal frame when rising. Can do. At the same time, building materials are not wasted.

<Manufacturing method>
As described above, the foundation reinforcement frame in the present embodiment is configured so that the horizontal and vertical positions of the vertical reinforcement frame 20 that reinforces the wall portion of the foundation can be freely adjusted. There is no need to perform operations such as cutting reinforcing bars in accordance with the dimensions of the foundation to be constructed on site. Therefore, the bar arrangement frame for the foundation can be manufactured in advance at a factory or the like, and can be used by being transported to the construction site.
Next, the process when manufacturing the reinforcing bar frame for foundation in this embodiment in a factory or the like will be described.

First, in order to create the horizontal reinforcing bar frame 10, a plurality of horizontal longitudinal bars 11 having substantially the same length are arranged in parallel with each other at substantially the same position at both ends.
Next, the horizontal horizontal bars 12a, 12b, and 12c are arranged so as to be substantially orthogonal to the plurality of horizontal vertical bars 11 arranged in parallel, and these intersections are fixed by welding or the like. .
Thus, the horizontal bar arrangement frame 10 is completed.

In the created horizontal reinforcement frame 10, the horizontal horizontal bar 12 a is at one end of the horizontal vertical bar 11, and the horizontal horizontal bar 12 b is at the intermediate portion in the length direction of the horizontal vertical bar 11. 12c is bridged to the other end of the horizontal longitudinal bar 11 respectively.
At this time, the horizontal horizontal bars 12a and 12b are bridged on the same surface side in the horizontal reinforcing frame 10 forming a substantially flat shape, and the horizontal horizontal bars 12c are bridged on the opposite side.

Next, in order to create the horizontal reinforcing bar frame 10, a plurality of vertical vertical bars 21 having substantially the same length are arranged substantially parallel to each other with both ends thereof substantially aligned.
Then, the vertical horizontal bars 22a and 22b are bridged to the plurality of vertical vertical bars 21 so as to be substantially orthogonal to each other, and these crossing portions are fixed by welding or the like, so that the frame body (the vertical horizontal bars 22c are still attached). A vertical reinforcement frame 20) that is not attached is created.
Here, the vertical horizontal bar 22a is at the open end of the vertical vertical bar standing part 21A constituting the vertical vertical bar 21, and the vertical horizontal bar 22b is at the intermediate part in the length direction of the vertical vertical bar standing part 21A. Each is laid. In addition, the vertical transverse bars 22a and 22b are spanned on the same surface side in the frame that forms a substantially flat shape.

FIG. 6 is a perspective view showing a process of attaching the created frame to the horizontal reinforcing frame 10 described above.
Next, as shown in the figure, the frame body 200 is horizontally arranged so that the vertical longitudinal bar construction part 21B side end of the vertical longitudinal bar 11 is loosely fitted in the lattice of the horizontal reinforcing frame 10. Insert and install in the muscle frame 10. At this time, the surface to which the vertical horizontal bars 22a and 22b are attached is set to the front side.

Then, with the frame body 200 being loosely fitted, the vertical horizontal bar material 22c is fixed to the entire back side of the vertical vertical bar material erection part 21B whose ends are aligned on a substantially straight line by welding or the like.
The foundation reinforcement frame is thus completed.

As described above, the portions of the vertical horizontal reinforcing bar 22c and the vertical vertical reinforcing bar installation portion 21B to which the load of the reinforcing bar for the foundation and the concrete foundation are applied are not fixed by welding or the like at the point, but firmly on the entire surface. Since it is fixed, it exhibits a remarkable effect in terms of strength resistance.
In addition, since the vertical horizontal bar member 22c and the vertical vertical bar member installation part 21B are fixed over the entire surface, alignment when fixing these members is easier than when fixing them with dots.

  In addition, since the vertical horizontal reinforcing bars 22a, 22b, and 22c are formed longer than the inner width between the horizontal vertical reinforcing bars 11 arranged at both ends of the horizontal reinforcing bar frame 10, the vertical reinforcing bar frame 20 is formed. The position of the vertical bar arrangement frame 20 can be adjusted without falling off the horizontal bar arrangement frame 10.

<Folding method>
When transporting the reinforcing bar frame for foundations manufactured as described above to the construction site, the vertical reinforcing bar frame 20 is turned around the vertical horizontal reinforcing bar member 22c and folded into a substantially flat shape, thereby arranging the reinforcing bar for the foundation. It becomes possible to make the whole frame compact and facilitate conveyance.
Hereinafter, the folding method of the foundation reinforcement frame will be specifically described with reference to the drawings.

FIG. 7 is a perspective view showing a reinforcing bar frame for foundation when folded in the embodiment of the present invention.
As shown in the figure, when folding, first, the vertical reinforcement frame 20 is moved to the front side (horizontal horizontal stripe 12c side).
Then, the vertical reinforcing bar frame 20 is rotated in the direction of the arrow with the vertical horizontal bar member 22c as a rotation axis so that the vertical horizontal bar member 22a approaches the horizontal horizontal bar member 12a. The frame 20 is folded so as to be substantially flush with each other.
FIG. 8 is a perspective view showing the folded state.
As shown in the figure, when the foundation bar arrangement frame is folded, the horizontal bar arrangement frame 10 and the vertical bar arrangement frame 20 form a substantially identical plane, become compact, can be easily transported, and reduce the storage space. Is possible.

  Next, the process up to the folding will be described in detail with reference to a side view of the reinforcing bar frame for foundation.

FIG. 9 is a side view of the foundation bar arrangement frame in a state where the vertical bar arrangement frame 20 is erected in the embodiment of the present invention.
As shown in the figure, when the vertical reinforcement frame 20 is erected, the vertical reinforcement frame 20 is substantially perpendicular to the horizontal reinforcement frame 10 and the installation surface.

FIG. 10 is a side view showing a state in the middle of folding the reinforcing bar frame for foundation in the present embodiment. A dotted line portion indicates the vertical reinforcing bar frame 20 in the upright state.
As shown in the figure, when the vertical reinforcing bar frame 20 in the standing state is moved to the front side (horizontal horizontal reinforcing bar 12c side), the vertical horizontal reinforcing bar 22c is rotated in the direction of the curved arrow in the drawing. The foundation reinforcing bar frame is folded so that the vertical reinforcing bar member 22a of the vertical reinforcing bar frame 20 approaches the horizontal horizontal bar member 12a of the horizontal reinforcing bar frame 10.

FIG. 11 is a side view showing a state in which the foundation reinforcing frame in the present embodiment is completely folded. A dotted line portion indicates the vertical reinforcing bar frame 20 in the upright state.
As shown in the figure, the vertical reinforcing bar construction portion 21B of the vertical reinforcing bar frame 20 is drawn until it abuts against the horizontal horizontal bar member 12c of the horizontal reinforcing bar frame 10, and the vertical vertical reinforcing member standing part 21A contacts the horizontal horizontal bar member 12b. When the above-mentioned rotation is performed until it comes into contact, the reinforcing bar frame for foundation can be folded.

At this time, the horizontal reinforcing frame 10 and the vertical reinforcing frame 20 are folded and overlapped so as to intersect in an X shape in a side view to form substantially the same plane.
In this way, when folded in an X shape when viewed from the side, as shown in the figure, the horizontal horizontal bars 12a, 12b, and 12c sandwich the X-shaped intersections below, below, and below the horizontal vertical frame 11 as viewed from the side. At the top.
On the other hand, the vertical cross bars 22a, 22b, and 22c are arranged above the vertical vertical frame 21 in order, above, and below the X-shaped intersection as viewed from the side.
That is, it is configured such that none of the horizontal bar members 12a, 12b, 12c, 22a, 22b, and 22c is positioned on the surface side sandwiched between the horizontal bar frame 10 and the vertical bar frame 20.
Therefore, when folded, the horizontal bars 12a, 12b, 12c, 22a, 22b, and 22c can be smoothly and thinly folded without coming into contact with the vertical bars 11 and 21.

<Effect in the present embodiment>
As described above, according to the reinforcing bar frame for foundation in the present embodiment, since one whole surface of the vertical vertical reinforcing member laying part 21B is joined to the vertical horizontal reinforcing bar member 22c, the vertical reinforcing bar frame that is most loaded is used. The bottom side of 20 can be firmly fixed, and there is a remarkable effect in terms of strength resistance.
Moreover, since it joins not the point but the whole surface, the alignment at the time of performing welding etc. becomes easy.
Further, when the vertical reinforcing bar frame 20 is erected, the vertical horizontal bar member 22c and the vertical vertical bar member laying part 21B are both in contact with the ground. When positioning before completely fixing the muscle frame 20, the vertical reinforcement frame 20 can be stably erected without unexpectedly falling down.

  Further, according to the reinforcing bar frame for foundation in the present embodiment, the vertical reinforcing bar frame 20 is rotated around the vertical horizontal reinforcing bar member 22c, and the horizontal reinforcing bar frame 10 and the vertical reinforcing bar frame 20 are viewed from the side X. By folding in a letter shape and finally in a substantially flat shape, the entire bar arrangement frame for the foundation can be made thin and compact and can be easily transported. In addition, the space can be reduced during storage.

  Further, according to the reinforcing bar frame for foundation in the present embodiment, when folded as described above, each of the horizontal bar members 12a, 12b, 12c, 22a, 22b, and 22c is arranged vertically with the horizontal reinforcing bar frame 10. Since it is configured not to be located on the side of the surface sandwiched between the muscle frames 20, the horizontal bars 12 a, 12 b, 12 c, 22 a, 22 b, 22 c abut against the vertical bars 11, 21 when folded. Without being able to fold smoothly and thinly.

  Further, according to the basic reinforcing bar frame in the present embodiment, the vertical reinforcing bar frame 20 is not directly fixed to the horizontal reinforcing bar frame 10, but is divided by the horizontal horizontal bar members 12 b and 12 c and the horizontal vertical bar member 11. It is possible to easily adjust the horizontal vertical and horizontal and vertical height positions of the vertical reinforcement frame 20 that reinforces the wall portion of the concrete foundation within the lattice.
