[Industrial applications]

 The present invention relates to a top level adjusting body for a cloth foundation, which enables the base mounting surface of the top of the cloth foundation to be formed accurately and efficiently.

[0002]

[Prior art]

 The top of the cloth foundation of the building needs to be finished horizontally in order to make the base sit better, but in the conventional construction method, concrete is placed between the confronting cloth foundation forming frames. After the concrete curing period has elapsed, the concrete was removed from the mold to form a cloth base substrate, and then fixed wood was applied to both upper ends of the cloth base substrate, and the top of the cloth foundation was finished with leveling mortar. .

[0003]

[Problems to be solved by the device]

 In such a conventional construction method, construction of the fabric foundation requires two works, that is, a work for forming the fabric base substrate and a subsequent work for leveling the top of the base, which requires a lot of time and effort for the construction work. In addition to the rise in the strike, there was a problem that the construction period was prolonged.

An object of the present invention is to provide a top level adjuster for a cloth foundation which is configured to reduce the construction cost and the construction period without the need for the top leveling work. .

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 5, the adjusting body 1 of the present invention is attached to a required height portion between the oppositely placed molds 2 and 2 for forming a cloth foundation (see FIG. 2), and the adjusting body 1 is driven between the molds 2 and 2. After curing the installed concrete 3, the horizontal base mounting portion 5 is formed (see FIG. 5), and as shown in FIGS. 1 to 3, the main body 7 having the smooth base receiving surface portion 6 faces each other. Fixing pieces 10 are provided on the upper edges of the side surface portions 9, 9 to be projected. In this embodiment, the adjusting body 1 is an integrally molded product of synthetic resin.

The adjusting body 1 of the present invention will be described in more detail as follows. That is, as shown in FIG. 1, the main body 7 has a plurality of base receiving pieces 12 each having a rectangular plate shape having a top end width that is substantially equal to the top width of the cloth foundation to be formed. The base receiving pieces 12, 12 are arranged side by side at a required interval, and the adjacent base receiving pieces 12, 12 are connected to each other by connecting pieces 13 on the lower sides of both end portions thereof. The base receiving surface portion 6 receives the lower surface portion 16 of the base 15 (see FIG. 5).

The thickness of the base receiving piece 12 is set in consideration of the shrinkage amount of the concrete 3 cast between the molds 2 and 2, and as shown in FIG. After curing the concrete, the lower part 17 of the base receiving piece 12 is in a state of being embedded in the concrete 3, so that the upper surface portion 11 of the base receiving piece 12 is located slightly above the concrete upper surface portion 19. Has been done.

Further, at the upper edges 20 of both ends of the base receiving pieces 12a, 12a located on the outermost side, the fixing piece 10 is provided with a bendable thin connecting piece (for example, parallel thin thin pieces) 21. It is projected to the side through. As shown in FIGS. 1 and 3, the fixing piece 10 is formed as a thin rectangular piece that can come into contact with the inner surface portion 22 of the form 2 when the thin connecting piece 21 is bent. A nail hole 25 is provided.

In this embodiment, dovetail-shaped anchor pieces 27, 27 are provided at both end portions of the lower surface of the base receiving pieces 12a, 12a, and an anchor is provided at a central portion of the adjacent base receiving pieces 12, 12 facing each other. A bolt holding portion 29 is provided. The anchor bolt holding portion 29 has two holding pieces 30, 30 which are parallel to each other and are spaced apart from each other at a lower edge portion of a central portion of the base receiving pieces 12, 12 facing each other so as to face each other. As shown in FIG. 4, the upper end portion of the anchor bolt 31 can be elastically held by the four holding pieces 30, 30, 30, 30.

Next, an example of how to adjust the crown level using the adjuster 1 according to this embodiment will be described. That is, first, as shown in FIGS. 2 to 5, concrete 3 is poured between the molds 2 and 2 for forming the cloth foundation to a required height.

After that, when the concrete is in a soft state, the fixing piece 10 that is projected upward by bending the thin connecting piece 21 is aligned with the marking line (not shown) attached to the inner surface of the formwork. When the adjusting body 1 is nailed to the inner surface portion 22, the adjusting body 1 is stably fixed at a required height portion between the molds. When the adjusting body 1 of the present invention is attached to the installation site of the anchor bolt 31, the upper end portion of the anchor bolt 31 can be held by the anchor bolt holding portion 29 until the cast concrete hardens.

When the fixing piece 10 is separated from the main body 7 by the thin-walled connecting piece 21 at the time of releasing the casting concrete after curing, as shown in FIG. 5, a horizontal base for receiving the lower surface portion 16 of the base 15 is obtained. The mounting surface portion 5 is naturally formed.

Since the portion of the connecting piece 13 lower than the upper side of the upper surface is embedded in the concrete 3, the anchor piece 27 and the holding pieces 30 ... Are placed in the concrete 3 in this embodiment. Since it is in the bite state, the lifting of the adjusting body 1 is reliably prevented.

Further, in the constructed cloth foundation, since the base mounting portion 5 is located slightly above the concrete upper surface portion 19, a ventilation gap 32 is formed between the base 15 and the concrete upper surface portion 19.

Further, in the present embodiment, since the adjusting body 1 is configured to connect a plurality of base receiving pieces in the shape of a rectangular plate having a relatively narrow width with the connecting pieces at intervals, the adjusting body 1 is connected to the main body 7. Even if the air is present between the concrete 3 and the concrete, the air is smoothly discharged from the side end of the base receiving piece 12. Therefore, a fine cloth foundation will be constructed without the need for special defoaming work.

Particularly, in this embodiment, since the anchor bolt holding portion is provided mainly on the main body, there are the following advantages. That is, in the past, when anchor bolts were planted on the foundation, the anchor bolts were pushed into the concrete in anticipation of an appropriate hardening time for the concrete placed between the formwork. It was very difficult to measure.

By the way, if this pushing time is mistaken, the concrete will be hardened too much, making it difficult to push in, and the constructed fabric foundation will be uneven in strength. Or the concrete is too soft, and the anchor bolt pushed in may fall or tilt under its own weight. The anchor bolt holding portion solves such a problem by holding the upper end portion of the anchor bolt in a stable fixed state until the concrete is hardened.

6 to 7 show another embodiment of the adjusting body 1 of the present invention, which is integrally molded of synthetic resin as a whole. The adjusting body 1 has a rectangular plate shape substantially equal to the top end width of the cloth foundation and has a lattice-like ventilation groove 35 on the upper surface portion 33. The fixing piece 10 is provided so as to project laterally via a thin connecting piece 21 (which is composed of parallel thin thin pieces).

As shown in FIG. 7, the adjusting body 1 configured in this way has a thin connecting piece 21 according to a mark such as a marking line attached to the form 2 as in the case of the above embodiment. When the fixing piece 10 that is protruded upward by bending is nailed to the inner surface portion 22 of the mold 2, the adjusting body 1 is fixed at a required height portion between the molds.

Then, when the fixed piece 10 is separated from the main body 7 by the thin connecting piece 21 during the demolding after the curing of the cast concrete, the horizontal base mounting surface portion 5 is formed in the same manner as shown in FIG. Will be formed. In this embodiment, as shown in FIG. 6, projecting pieces 37 are provided at the lower ends of both end surface portions 36, 36 of the main body 7 and the end surface portions 36, 36 are fitted with the projecting pieces 37. The recess 39 is formed.

The projecting piece 37 functions as an anchor (see FIG. 7) and fits with the fitting recess 39 to stabilize the stacking of the adjusting body 1. An elongated hole 40 extending in the width direction is provided in the central portion of the upper surface portion 33 of the main body 7 near both ends, and an anchor bolt 31 is elastically attached to the opposite edge portion of the elongated hole 40 as shown in the figure. An anchor bolt holding portion 29, which is composed of a pair of elastic small projections, is provided to hold the anchor bolts.

In addition, in the adjusting body 1 of the present invention, the shape of the main body 7 is not limited to that shown in the above-mentioned embodiment, and may be any shape as long as it has the smooth base receiving surface portion 6. In particular, when the anchor bolt holding portion 29 is provided as shown in the embodiment, the holding portion 29 holds the upper end portion of the anchor bolt 31 such as an assembly of elastic triangular holding pieces formed by radial cuts. Various configurations can be adopted.

Contrary to the case shown in the above-mentioned embodiment, the adjusting body 1 may be fixed between the molds 2 and 2, and then concrete may be poured between the molds 2 and 2. .
