Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to an anchor device.

[Background technology]

In a prefabricated house, in order to connect the wall panel 1 to the fabric foundation 2 as shown in FIGS. An intermediate bolt 7 is screwed into the bolt 5 that has been inserted, and the intermediate bolt 7 is inserted into the bolt insertion hole 4 of the anchor member 4 through the plate 8.
Pass through a and tighten nut 9. After the wall panel 1 is installed, the recess 3 of the cloth foundation 2 is filled with mortar.

In this case, the formation of the recess 3 of the cloth foundation 2 and the embedding of the anchor member 4 into the cloth foundation 2 are performed as shown in FIGS. 3 to 6. That is, as shown in FIG. 3, concrete 11 is poured between formworks 10, and while the concrete 11 is not hardened, the anchor member 4 is embedded into the concrete 11 together with the foamed polystyrene 12 arranged on the top thereof. . As shown in FIGS. 4 to 6, this Styrofoam 12 has a width equal to the width of the cloth foundation 2, and is embedded so that the upper surface 12a is flush with the top end 2a of the cloth foundation. After the concrete 11 hardens, the formwork 10 is removed, the Styrofoam 12 is removed, and a recess 3 is formed behind the area where the Styrofoam 12 is provided.

However, since the Styrofoam 12 must be removed by breaking the Styrofoam 12, the removal work is difficult, and the Styrofoam 12 cannot be reused. In addition, the recess 3 of the cloth foundation 2 is
Therefore, when the recess 3 is filled with mortar, it feels uncomfortable with the concrete 11 and spoils the aesthetic appearance.To prevent this, conventionally, mortar is further coated on the concrete 11 and the outdoor surface of the mortar. There was also the problem that the mortar application process was complicated.

Therefore, in order to omit the mortar application work, the width of the cloth foundation 2' is set slightly larger than the width of the Styrofoam foam 12, as shown in FIGS. 7 and 8, and the Styrofoam 12 is then A proposal has been made to prevent the concave portion 3' after removing the Styrofoam 12 from being exposed to the outdoor side of the fabric foundation 2' by locating it on the outdoor side.
However, in order to save on the amount of concrete used, the width of the cloth foundation cannot be made large, and the width of the cloth foundation transition section 13 corresponding to the recess 3' becomes narrow, and this transition section 13 is likely to be damaged when the Styrofoam 12 is removed. I had a new problem. Of course, removing the Styrofoam 12
The same problem as the conventional example shown in FIGS. 4 to 6 remains, in that the removal work is difficult because the foam 12 must be destroyed, and the foamed polystyrene 12 cannot be reused.

[Purpose of invention]

The purpose of this invention is to make it possible to easily remove concrete removal blocks such as styrofoam, to reuse the concrete removal blocks, and to omit the work of applying mortar on the outdoor surface of the cloth foundation. An object of the present invention is to provide an anchor device that can also prevent damage to the anchor.

[Disclosure of the Invention]

The anchor device of this invention consists of an anchor member with a hole for connecting wall panels drilled in the main body and anchor legs protruding around the hole on the bottom surface of the main body, and an anchor member whose height is lower than the anchor legs and extends from one side to the other. A linear groove for insertion is cut into the anchor leg, and by inserting the anchor leg in a removable manner along the linear groove, the area including the hole on the lower surface of the main body is covered, and the other side of the anchor leg is positioned on the indoor surface of the fabric foundation. It is equipped with a concrete removal block that is embedded from approximately the center of the top of the cloth foundation to the indoor side. In this way, since the concrete removal block has a straight groove for inserting anchor legs, the concrete removal block can be easily removed by simply pulling it out to the indoor surface of the fabric foundation along the straight groove for inserting anchor legs after the concrete has hardened. Moreover, since there is no need to destroy the concrete removal block, it can be reused. Furthermore, since the concrete removal block is placed from approximately the center of the top of the cloth foundation to the indoor side, the transition part of the cloth foundation can be made thicker to prevent damage, and the work of applying mortar on the outdoor surface of the cloth foundation can be omitted. .

An embodiment of this invention will be described with reference to FIGS. 9 to 11. That is, as shown in FIG. 9, this anchor device is composed of an anchor member 14, a thick polystyrene foam 15 and a thin polystyrene foam 16, which are concrete removal blocks.
The anchor member 14 has a bolt insertion vertical hole 14b formed in the center of a flat metal main body 14a, and anchor legs 14c protruding around the vertical hole 14b on the lower surface of the main body 14a.

The thick styrofoam 15 has a height lower than the anchor legs 14c, and has a main body fitting recess 15 on one side of the upper surface.
a, and a straight groove 15b for inserting an anchor leg is formed from one side 15c toward the other side. As shown in FIGS. 10 and 11, this thick Styrofoam 15 has a width approximately half the width of the cloth foundation 17, and the anchor leg 14c is removably inserted into the straight groove 15b for inserting the anchor leg. , covering the area including the vertical hole 14b on the lower surface of the main body 14a.

The thin Styrofoam 16 has a body fitting recess 16a formed on one side of the upper surface, and a body fitting recess 16a formed on one side 16c.
Anchor leg insertion straight groove 16b toward the other side.
, whose width is the thick styrofoam 15
The width is approximately 1/3 of that of the original.

The construction procedure is as shown in FIGS. 10 and 11 after pouring concrete into a formwork (not shown) and while the concrete is still uncured.
While holding it in step 6, push it into the concrete.
In this case, the other side 15 of the thick styrofoam 15
d coincides with the interior surface 17a of the cloth foundation. Once the concrete has hardened, remove only the thick Styrofoam 15 by pulling it toward the indoor side of the fabric foundation 17 along the straight groove 15b, and anchor the wall panel (not shown) in the same manner as in Figures 1 and 2. Part 1
4 through a vertical hole 14b. Finally, the recess 18 formed by removing the thick Styrofoam 15
Then, fill with mortar and complete the construction.

As described above, since the straight grooves 15b for inserting anchor legs are provided in the thick styrene foam 15, the thick styrene foam 15 can be easily removed by simply pulling out the thick styrene foam 15 along the straight grooves 15b after the concrete has hardened. I can do it, and also.
Since the thick styrofoam 15 can be removed without breaking it, it can be reused. Further, since both the polystyrene foam 15 and 16 are buried on the indoor side of the cloth foundation 17, a concrete transition portion 19 can be formed on the outdoor side of the anchor member 14, and mortar finishing work on the outdoor surface 17b of the cloth foundation can be omitted. Moreover, since the width of the thin styrofoam 16 is set thin, the width of the transition portion 19 can be increased, and the width of the transition portion 19 can be increased.
This increases the strength of the material and prevents it from being damaged. Although the thin Styrofoam 16 will be left behind in the cloth foundation 17, since its width is extremely thin compared to the width of the cloth foundation 17, no problem will arise in terms of the strength of the cloth foundation. However, the thin styrofoam 16 is not necessarily necessary and may be omitted.

In the above embodiment, foamed polystyrene was used as the concrete removal block, but the material is not particularly limited.

[Effect of idea]

According to the anchor device of this invention, the concrete removal block can be easily removed and the concrete removal block can be reused, and the work of applying mortar on the outdoor surface of the cloth foundation can be omitted, and the work of applying mortar to the outside surface of the cloth foundation can be removed. This has the effect of preventing damage to the
