Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cloth that is wrapped around the main reinforcing bars disposed within the cloth foundation in order to strongly reinforce it when constructing a cloth foundation for a wooden house, etc. This invention relates to a method of arranging lattice bars for foundations and lattice bars for fabric foundations.

[Technical background of the invention and its problems] Conventionally, this type of lattice reinforcement for fabric foundations has been used for its transportation,
For convenient storage and organization, a spiral band 1 is made by forming curved parts at each corner and winding the wire in a spiral shape with no gaps between the straight parts in the direction of the winding axis to shorten the overall length.
0 (see Figure 1 (a)), this was wrapped around the main reinforcement 13.13 at the work site, and then forcibly stretched to arrange the reinforcement (see Figure 1 (b)) However, when the spiral band muscle 10 is stretched, the curved part 11 is not deformed and the straight part 12, which is weaker in strength than the curved part 11, is deformed, so the spiral band muscle 10 is stretched as a whole while being slightly twisted. In this case, the wrapping around the main reinforcement 13 is not neatly arranged, and this must be repaired later.Furthermore, it is difficult to obtain a uniformly stretched state with a uniform pitch, and it is also difficult to fully stretch the reinforcement, making it difficult to arrange the reinforcement. It was very troublesome and the work efficiency was low.

In particular, since the spiral band reinforcement 10 is forcibly deformed plastically, plastic strain remains within the spiral band reinforcement 10, which becomes a major obstacle to repair work and causes a decrease in work efficiency. In addition, when arranging this spiral tie reinforcement 10 for a cloth foundation, first, each spiral tie reinforcement 10 is slightly stretched to create a gap between the straight parts 12, and another spiral tie reinforcement is placed in this gap. 10, and insert the spiral band 11 into the spiral band 1.
0 are superimposed on each other, and then the curved portion 1 of the spiral band 10 is
After inserting the main reinforcing bars 13 into each of the main reinforcements 13, the spiral ties 10 are fully stretched and arranged, but it is difficult to overlap the spiral ties 10 in an orderly manner, and the handling is difficult, making the reinforcement work very difficult. It was becoming a hassle.

Furthermore, the conventional spiral band reinforcement 10 is formed by processing a wire material (burn coil) that is appropriately wound into a roll shape.
This wire rod wound into a roll has a fixed length (maximum 12
It was about 20% more expensive per unit length than a steel bar (about 300 ft), so it was not very economical.

[Object of the Invention] Therefore, the present invention aims to solve the conventional problems as described above, and to improve the work efficiency by making it possible to quickly and easily perform the work of arranging lattice reinforcement for cloth foundations. It is an object of the present invention to provide a lattice strip for fabric foundations that is extremely economical and easy to handle.

Summary of the Invention] The lattice strip for fabric foundation according to the present invention has the following features:
A spirally curved part that can circumscribe a pair of main reinforcing bars is formed at each corner, and the steel bar is spirally wound at an appropriate pitch when winding around the main reinforcing bars so that the spirally curved parts are connected by a straight part. The gist is that a spiral lattice muscle is formed by winding, a plurality of spiral lattice muscles are overlapped in a direction connecting the winding axis of the spiral lattice muscle and a spiral curved part, and these are bundled by an appropriate binding means, In addition, in the method for arranging lattice reinforcements for fabric foundations according to the present invention, the lattice reinforcements for fabric foundations, which are bundled by overlapping a plurality of spiral lattice reinforcements, are untied, and the first spiral lattice reinforcements are Remove the second spiral lattice muscle in its overlapping state, insert the first main reinforcement into each spiral curved part of one of the first spiral lattice muscles,
Furthermore, a second main reinforcement is inserted through each of the spiral curved portions of one of the second spiral lattice muscles, and a third main reinforcement is inserted through each of the other spiral curved portions of the second spiral lattice muscle. The second main reinforcement is moved to the winding axis position of the spiral lattice reinforcement, and the first spiral lattice reinforcement is moved so that each of the other spiral curved parts is circumscribed by the second main reinforcement in a encapsulated manner. The helical curved part of the spiral lattice muscle is temporarily fixed with an appropriate means, and the first spiral lattice muscle is brought into an erect state with respect to the second spiral lattice muscle, and one spiral curved part of the second spiral lattice muscle is The purpose of the above-mentioned objective was to be achieved by inserting a fourth main reinforcement into each section.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the lattice reinforcement for the fabric foundation according to the present invention is suitably made of a standard length bar I.
I (Length of about 12 m even for II size) with suitably uniform pitch, and the shape of -pitch in the direction of the winding axis is approximately a flat oval ring shape (for example, the long axis is about 60α and the short axis is the main bar). A spirally curved part 1 is formed at each corner of the main bar B by winding it in a spiral shape, and forming a spirally curved part 1 that can circumscribe a pair of parallel main bars B in an enveloping manner. , a spiral lattice muscle A is formed by connecting the spirally curved portions 1 with the straight portions 2.

By the way, the pitch of this spiral lattice muscle A is the pitch when winding the spiral lattice muscle A around the main reinforcement B (for example, 3
00), and its total length is approximately 3 m in consideration of transportability and the like. Then, a plurality of spiral lattice muscles A1. A2゜A3. While overlapping A4 and A5 (in the illustrated example, there are five, but any number is fine),
These are formed by bundling them together via a binding tool 5.

In addition, the steel bar to be wound can be of various sizes, and the shape and size of the spiral lattice bar A can be
- The spacing between the bits can be set freely depending on the size, shape, etc. of the cloth foundation.

Furthermore, a binding device 5 for binding a plurality of spiral lattice muscles A is provided.
As shown in the example shown in the figure, a small piece is brought into contact with the inner ring surface of the straight part 2 (so that it is located within the spiral to the spiral lattice muscle), and together with this small piece, the straight part 2 is connected with a wire, string, etc. It may be configured to be tied as appropriate, or it may be configured to have any other arbitrary configuration as appropriate.

In addition, the method for arranging lattice reinforcement for a fabric foundation according to the present invention includes untying the binding tool 5 for lattice reinforcement for a fabric foundation configured as described above, and connecting the first spiral lattice reinforcement A1 and the second spiral lattice reinforcement A1 to the second spiral lattice reinforcement. The lattice muscle A2 is removed in its superimposed state, and the first main muscle B1 is inserted through each of the spiral curved parts 1a of the first spiral lattice muscle A1, and then the second spiral lattice muscle A is inserted into the second spiral lattice muscle A.
The second main reinforcement 82 is inserted into each of the spirally curved portions 1b of the second spiral lattice reinforcement A2, and the third main reinforcement B3 is inserted into the other spirally curved portion 1b' of the second spiral lattice reinforcement A2.
(See Figure 3).

The first main reinforcement 81 and the second main reinforcement B2 are connected to one of the spiral curved portions 1a of the first spiral lattice reinforcement A1 and one of the second spiral lattice reinforcement A2 before untying the binding tool 5. They may be inserted into the spirally curved portions 1b in advance so that the first spiral lattice muscle 'AI and the second spiral lattice muscle A2 can be removed in a superposed state without coming apart.

Then, the second main IB2 is moved to the winding axis position of the second spiral lattice muscle A2 (the central part of the second spiral lattice muscle A2), and this second main reinforcement B2 is moved to each of the spiral curved portions 1a. Move the first spiral lattice muscle A1 so that it circumscribes the spiral lattice muscle A, and tie the spiral curved part 1 of the spiral lattice muscle A and the main reinforcement B with a wire or the like and temporarily fasten them as appropriate (Fig. 4). reference).

Next, the first spiral lattice muscle A1 is slightly raised in the upright direction relative to the second spiral lattice muscle A2, which is the foundation of the footing, and four spiral lattice muscles The second main muscle B4 is inserted through the main muscle B4 (see FIG. 5), and the first spiral lattice muscle A1 is placed in an erect state relative to the second spiral lattice muscle A2 (see FIG. 6).

After this, the contact portion between the main reinforcement B and the spiral lattice reinforcement A is fixed with wire or the like, or by spot welding, and then concrete 1 is poured.

[Effects of the Invention] Therefore, according to the lattice reinforcement for cloth foundations according to the present invention, since the steel bar is spirally wound at the pitch used when winding it around the main reinforcement B in advance, the lattice reinforcement can be wound like a conventional spiral reinforcement. The entire spiral lattice muscle A is not twisted, and each of the spiral curved parts 1 of the spiral lattice muscle A can be arranged neatly on a straight line,
The work of inserting the main reinforcement B into each of the spirally curved portions 1 can be performed smoothly, and the reinforcement for the cloth foundation can be quickly and easily performed.

Furthermore, since each spiral lattice reinforcement can be formed in advance to have a uniform pitch, it becomes possible to wrap it around the main reinforcement B uniformly, and the fabric foundation can be reinforced almost uniformly, increasing the strength. Balanced reinforcement becomes possible. Further, a large number of spiral lattice muscles A can be polymerized in an orderly manner without becoming too tense, and handling thereof becomes extremely easy.

Moreover, since each spiral lattice muscle A is bound by the binding device 5, transportation, storage, and organization thereof are facilitated. Furthermore, by winding the steel bar in a spiral shape and making the entire length of the spiral lattice muscle A about 37FL, its transportation,
It will not cause any problems in storage and organization.

In particular, since the spiral lattice striations A are formed from steel bars, they can be formed at a lower cost than those conventionally formed by processing wire rods wound into rolls (burn coils). This type of lattice reinforcement for fabric foundations, which is used in large quantities, is very economical.

Further, according to the method of arranging lattice reinforcement for cloth foundations according to the present invention, reinforcement work for cloth foundations can be performed extremely easily and quickly.
The work efficiency of reinforcement work can be further improved.

Moreover, the spiral lattice reinforcement A itself does not need to be bent or repaired at all, making it much easier to insert the main reinforcement B into the spiral curved portion 1 than with conventional reinforcements, and it also allows for straight alignment. Reinforcement is easy to perform, and it is the best method for arranging reinforcement for cloth foundations.

Furthermore, anyone can easily assemble the main reinforcement B and the spiral lattice reinforcement in an orderly manner, and a strong reinforcement arrangement can be reliably obtained.

As explained above, according to the present invention, it becomes possible to arrange reinforcement for concrete foundations extremely easily and quickly, which greatly helps improve the work efficiency of reinforcement work, and furthermore, the reinforcement is arranged in a solid state with uniform strength. This makes it possible to uniformly reinforce the cloth foundation, and has excellent effects such as being simple in structure, easy to manufacture, and inexpensive to provide.
