This invention relates to a top level adjustment body for a cloth foundation that can be formed accurately and efficiently.

(Conventional technology) The top of a building's cloth foundation needs to be finished horizontally to improve the seating of the foundation. After pouring concrete and demolding the concrete after a curing period to form a cloth foundation base, placing fixed trees on both sides of the upper end of the cloth foundation base,
The top of the cloth foundation was finished with leveled mortar.

(Problems to be solved by the invention) In such conventional construction methods, when constructing a cloth foundation,
Two works were required: forming the cloth foundation base and then leveling the crown, which required a lot of work and caused an increase in construction costs, as well as prolonging the construction period. .

The object of the present invention is to provide a top level adjuster for a cloth foundation that is configured to eliminate the need for the above-mentioned top leveling work, thereby reducing construction costs and shortening the construction period.

(Means for Solving the Problems) A cloth foundation top level adjuster (hereinafter referred to as an adjuster) 1 according to the present invention is fixed to opposing side surfaces 9, 9 of a main body 7 having a smooth base receiving surface 6. protrusion 10,
10 is provided in a protruding manner, and the main body 7 is placed in a protruding state at a required height between the opposed formworks 2 for forming a cloth foundation, due to the elastic force caused by the deformation of the fixing protrusion 10. It is characterized by being fixed with.

10 is installed protrudingly. In this embodiment, a wooden formwork is used, and the adjusting body 1 is an integrally molded product made of synthetic resin.

The adjusting body 1 of the present invention will be explained in more detail as follows. That is, as shown in FIGS. 1 and 2, the main body 7 is a base support piece 12 having a slightly elongated rectangular plate shape approximately equal to the top width of the cloth foundation to be formed, and having a smooth upper surface portion 11. A plurality of these are arranged side by side at required intervals, and adjacent base support pieces 12, 12 are connected to each other by a connecting piece 13 at the lower side of both ends thereof, and the upper surface of each base support piece 12... 11... is the foundation 15
This becomes the base receiving surface portion 6 that receives the lower surface portion 16 of the base (see FIG. 6). The thickness of the foundation support piece 12 is determined by considering the amount of shrinkage of the concrete 3 placed between the formworks 2, 2, etc., and as shown in FIG. The lower part 17 of the support piece 12 (for example, the part below the upper surface of the connecting piece 13) is embedded in the concrete 3, and the upper surface part 11 of the base support piece 12 is slightly above the concrete upper surface part 20. It is said that it is located at

Further, on both end surfaces of each base receiving piece 12, for example, whisker-shaped protrusions 21, 21 made of semi-hard synthetic resin or soft synthetic resin are protruded, and the opposing side surfaces 9, 9 of the main body 7 Each protrusion 2 protruding in

The fixing protrusions 10, 10 on both sides of the main body 7 are attached to the formwork 2, 2.
in contact with the inner surfaces 22, 22 of the fixing protrusion 1
Due to the deformation of 0 and 10, the main body 7
(See Figure 4).

In this embodiment, fixing pieces 23, 23 are provided at both ends of the outermost base receiving pieces 12a, 12a (see FIG. 1), and anchor pieces 25 are provided at both ends of the lower surfaces of the base receiving pieces 12a, 12a. , 25 (see FIG. 2), and an anchor bolt holding portion 26 (first to
(see FIGS. 2 and 5), each of which is provided integrally with the main body 7. The fixing piece 23 is used as necessary to further securely fix the adjusting body 1 to both the formworks 2, 2, and is used when the adjusting body 1 is in a tensioned state. Formwork 2 in a state fixed between
(see FIG. 4), and its lower edge 27 is connected to the upper edge 30 of the end of the base receiving piece 12 via a thin connecting portion 29. (See FIG. 1), and a nail hole 31 is provided in the center thereof. Note that a notch 32 is provided on the inside of the continuous portion, so that the fixing piece 2 can be removed during demolding.
3 and the base receiving piece 12 are easily separated at the thin connecting portion 29. The anchor piece 25 is formed into a dovetail shape that becomes wider as it goes downward. Further, the anchor bolt holding portion 26 is formed of two parallel parts separated by a small interval at the lower edges of the opposing center portions of the adjacent base receiving pieces 12, 12.
The book holding pieces 33, 33 are protruded so as to face each other,
As shown in FIG. 5, four holding pieces 33, 33,
The upper end portion of the anchor bolt 35 can be elastically held by the anchor bolts 33, 33.

Next, an example of how to adjust the top level using the adjustment body 1 according to this embodiment will be explained.

That is, first, as shown in FIGS. 3 to 6, concrete 3 is poured to a required height between formworks 2 and 2 for forming a cloth foundation. It should be noted that on the inner surfaces of the formworks 2, 2, after curing of the poured concrete 2, a portion slightly above and below the top surface of the connecting piece 13 of the adjusting body 1 is covered with concrete 3.
Marking lines (not shown) are provided in consideration of the degree of shrinkage of the poured concrete and the thickness of the adjustment body 1 so that the adjustment body 1 is embedded in the concrete.

Thereafter, when the concrete is soft, the adjusting body 1 is positioned in line with the marking line so that its base receiving surface 6 is horizontal, and is pushed between the formworks 2 at a required interval. Regulator 1
As shown in FIG. 4, the fixing protrusions 10, 10
Due to the elasticity caused by the deformation of the molds 2 and 2, a tension is created between the formworks 2 and 2, and furthermore, the fixing protrusion 1
0 and 10 are stably fixed by biting into the inner surfaces of the wooden forms 2 and 2. If necessary, as shown in Figures 3 and 4, fixing piece 2
3 is nailed to formwork 2. Further, when the adjusting body 1 of the present invention is attached to the location where the anchor bolt 35 is installed, the upper end portion of the anchor bolt 35 can be held by the anchor bolt holding portion 26 until the poured concrete hardens.

When the cast concrete is removed from the mold after curing, a horizontal base mounting surface 5 for receiving the lower surface 16 of the base 15 is automatically formed as shown in FIG. In addition, since the upper and lower parts of the upper surface of the connecting piece 13 are embedded in the concrete 3, in this embodiment, the anchor piece 25 and the holding piece 26... are stuck in the concrete 3. Therefore, lifting of the adjustment body 1 is reliably prevented. Furthermore, in the constructed cloth foundation, since the base mounting surface portion 5 is located slightly above the concrete upper surface portion 20, a ventilation gap 36 is formed between the foundation 15 and the concrete upper surface portion 20. In addition, in this embodiment, the adjusting body 1 has a plurality of relatively narrow rectangular plate-shaped base receiving pieces connected by connecting pieces at intervals, and each connecting piece 13 has whisker-like shapes on both end surfaces. Since the fixing protrusions 10, 10 consisting of protrusions are provided, even if air is present between the main body 7 and the poured concrete 2, the air will flow through the base support piece 1.
2, and the gap formed between the side surface 9 of the base support piece 12 and the inner surface 22 of the formwork 2 due to contact between the fixing protrusions 10, 10 and the inner surface 22 of the formwork 2. It is smoothly discharged from g, etc. Therefore, a dense cloth foundation can be constructed without requiring any special defoaming work.

In the adjustment body 1 of the present invention, the shape of the main body 7 is as follows:
It is not limited to what was shown in the above embodiments, but any type may be used as long as it has a smooth base receiving surface 6, and may be formed as a rectangular plate or the like. In particular, when the anchor bolt holding part 26 is provided as shown in the embodiment, the holding part 2
Reference numeral 6 denotes an elastic material for the upper end portion of the anchor bolt 35, such as a pair of retaining pieces installed at intervals between the base receiving pieces, or an assembly of triangular retaining pieces formed by radial cuts. It is possible to employ various configurations for holding the memory.

In addition, contrary to the case shown in the above embodiment, concrete may be poured between the formworks 2 and 2 after the adjusting body 1 is fixed between the formworks 2 and 2.

(Effect of the invention) The adjusting body of the present invention has a fixing protrusion made of an elastic body protruding from the opposite side surface of the main body having the base receiving surface. By fixing the formwork in a tensioned state to the required part of the formwork for forming the cloth foundation using the elastic force, the foundation mounting surface of the top of the cloth foundation can be easily fixed without requiring the leveling work of the top as in conventional construction methods. can be formed accurately and efficiently, reducing construction costs and shortening the construction period. In addition, since the adjustment body is fixed by utilizing the elastic force caused by the deformation of the fixing protrusion, the adjustment body can be positioned and fixed easily and quickly. Even if there is variation in the fixing protrusion, the variation is automatically absorbed by slightly changing the deformation state of the fixing protrusion.

As shown in the embodiments, when the main body is provided with an anchor bolt holding portion, the following special effects are produced. That is, conventionally,
When placing anchor bolts in the foundation, the anchor bolts were pressed into the concrete while waiting for the appropriate time for the concrete poured between the formwork to harden. It was difficult. Incidentally, if you misjudge the timing of this pushing, the concrete will harden too much, making it difficult to push in, and the constructed fabric foundation will have uneven strength. Alternatively, the concrete may be too soft and the anchor bolts pushed in may sag or tilt under their own weight. The anchor bolt holding portion solves this problem by holding the upper end portion of the anchor bolt in a stable fixed state until the concrete hardens.
