Description

  The present invention relates to a fabric foundation for wooden construction. More specifically, the present invention relates to a combination of a sloped reinforcement at the top of the fabric foundation and a cylinder for the air hole, and an underfloor ventilation method for the foundation with two air holes.

Traditionally, in a private house over a hundred years, the bottom of the base tree was transparent, and the pillars of the base were only placed on the foundation stone, but even when exposed to wind and rain, they escaped from corrosion due to ventilation.
In recent years, when concrete cloth foundations were used, it was natural that many square wind windows were set in consideration of ventilation by making use of the experience of past carpenters.
However, for the purpose of cost reduction, the number of wind windows is set to be small. Recently, the wind windows are omitted, and the upper surface of the upright portion is made flat, and a large number of cushioning materials are placed to ventilate the gaps.
As a result of such cut-out work, the durability of Japanese wooden buildings has been shortened to 30 to 50 years. Last year, a two hundred-year housing concept was launched by the government. There are no proposals for technological innovation in the fabric foundation part of wooden buildings.
Furthermore, since the cushioning material of the fabric foundation is rapidly deteriorated, there is a possibility that the uneven settlement of the house will cause problems within 100 years, and the box-type air hole is troublesome and is no longer used in terms of cost. There is a problem.

  The present invention has (1) a low cost, (2) wind ventilation structure at the top of the fabric foundation, (3) a circular cylindrical air hole with a circular cross section in two upper and lower stages, and (4) a cylinder for the air hole. It is easy to attach to the reinforcing bar by installing a locking tool on the top, ▲ 5 ▼ simplify the removal of the cylindrical frame, ▲ 6 ▼ incline the reinforcing bar in the upper part to save the reinforcing bars and increase the strength, ▲ 7) To set the cylinder stably between the inclined reinforcements.

The present invention
In Claim 1, the reinforcement of the main part of the upright is a fabric foundation upright comprising at least upper and lower horizontal bars and inclined support bars that are inclined and coupled to the upper and lower horizontal bars,
According to a second aspect of the present invention, the bar arrangement of the main part of the upright part is at least one of the upper and lower horizontal bars, and the upper and lower horizontal bars are adjacent to or joined to the ends of the bent bars bent at a predetermined angle at the center. A fabric foundation comprising an upright portion constructed by welding to the horizontal streaks and bending portions to the other horizontal streaks,
According to the third aspect of the present invention, a plurality of air hole cylinders or air hole cylindrical frames are formed between the inclined support bars of the uprights or between the inclined support bars and the upright bars, and a loop-shaped hook is formed on the wire-like locking tool. It is a wind hole construction method of the cloth foundation upright according to claim 1 or 2 configured to be locked by a method,
According to a fourth aspect of the present invention, a large number of the air hole cylinders or the air hole cylindrical molds are arranged in two upper and lower stages on the cloth foundation standing by a method other than forming a loop-like hook portion on the wire-like locking tool. Claim 5 is an underfloor ventilation method based on the air hole construction method of the fabric foundation according to claim 1 or claim 5. Claim 5 is a wire-like engagement between the adjacent reinforcing bar and the air hole cylinder or the air hole cylindrical formwork at the lower limit lowering by gravity. It is a cloth foundation construction method consisting of an upright portion that is configured to be locked to the bar arrangement by a method other than forming a loop-shaped hook portion on the stopper,

In the early days of using concrete foundations for wooden construction, there were many box-shaped large wind windows due to the experience of the traditional under-floor see-through building, but in recent years it has tended to be abolished. The present application is A. The cylindrical form for the air hole can be easily used by cutting a predetermined dimension of the resin pipe,
B Cylinder air hole cylinders can be used by cutting with predetermined dimensions as well as molds, and C disk-shaped ventilation lids can be manufactured at low cost.
D Outer diameter reduced formwork is easy to extract,
E The upper and lower air hole two-stage arrangement has excellent ventilation.
F Tilting support bar makes it easy to set the cylinder temporarily.
G In summer, the cool air of the earth blows on the lower surface of the floor to cool the room. In winter, the lower surface of the ground is warmed at a temperature of 10 ° C. or more, so the cold is relieved.

Although the air hole cylinder may be a piece of earthen pipe, it is possible to use a commercially available resin long pipe in the use of a material that can be reused repeatedly for the air hole cylindrical form in consideration of cost. In order to facilitate extraction, it is desirable to spray and lock an oily liquid on the outer surface. An annealed wire can be used as the locking tool. There is a method of making a loop so that it can be pulled out by hooking on the loop, but other than that method may be locked to the reinforcement, for example, it may be fixed to the reinforcement by turning around the ring around the outer periphery, Two holes are drilled close to each other, and both ends of the external reinforcement are inserted one by one and bound inside, or from the inside to the outside, it can be bound to the reinforcement and wired. It is obvious that various means such as fixing the clip to the outer periphery can be considered although not shown.
The outer peripheral wall reduced cylinder can be produced individually and pulled out easily.
As for the reinforcement in the upper part, if a large number of reinforcing bars inclined to the upper and lower horizontal bars are bent at a predetermined interval and bent at a predetermined angle at the center as shown in the figure, the number of welds will be reduced. It can save labor. It is desirable to add a horizontal streak at the center when high strength is required. Vertical compression strength can be increased by adding an upright streak.
These will be described in more detail with reference to one embodiment,

In FIGS. 1 and 2, the reinforcement of the raised portion of the conventional foundation is an assembly that forms a quadrangle, and the intersecting portion is bound with a welded or annealed wire, and as shown in FIG. Assembling, the binding with the reinforcement for setting the cylinder for the air hole was unstable (FIG. 2).
If the bar arrangement is inclined, it is easy to stabilize by simply twisting the bifurcated portion 2 of the locking tool (FIG. 3).
3 to 5, the balance of the center of gravity is good, and it is easy to assemble the form of the entire bar arrangement, and the cylinder can be locked stably. In FIG. 5, the bifurcated portion 2 of the locking tool 5 protrudes from the locking hole 4 to the outside of the peripheral wall and is easy to be coupled to the bar arrangement. The part 3 is in close contact with the inner wall of the cylindrical mold 1 but is held in that position (FIG. 7). And it can be temporarily fastened between the inclined muscles in a balanced manner in terms of weight (FIG. 8).
The cylinder is stable between the upright and slanted muscles or between the slanted and slanted muscles, when it is lifted to the limit by gravity, or lifted and locked at the upper limit, so that the position does not shift at the time of feeding the raw control.
Therefore, the cylindrical form having the configuration shown in FIG. If a liquid with a good sliding property is sprayed or applied to the outer periphery of the cylindrical form frame 1 before setting, the work of extracting is easy.

  In FIG. 6, the horizontal streaks are arranged in the middle to increase the strength, and this is a configuration of the upright portion that is convenient for partial excision.

In FIG. 7, vertical compression strength can be increased by adding upright bars between the inclined bars, and it is relatively convenient for setting the surrounding bars after partial cut removal.
The present invention is not limited to the above example.

  In the present invention, as the basic structure, the underfloor is transparent and the ventilation is improved, so that the durability of the lower part of the wooden building can be dramatically improved, and the long life of an old Japanese house over two hundred years old I'll be Therefore, it saves timber and leads directly to forest protection. This technology contributes to environmental protection by protecting forests and promoting coastal fisheries.
