Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a grouting shield material used for embedding an anchor bolt fixed to a base of a building in a base sheath tube.

[Background Art] As shown in FIG. 2, for example, in assembling a unit house 1, a sheath tube 3 is embedded in a foundation 2, and an anchor bolt 8 attached to a beam 7 of a housing unit is installed in the sheath tube 3. In order to prevent the grout material 9 from flowing out of the sheath tube 3 and the foundation 2 when pouring (grouting) the grout material 9 for fixing the grouting material 9, a quadrangular shield material 4 made of sponge is attached to the sheath tube 3. It is arranged on the upper surface of the base 2 so as to surround the upper end opening of the base 2.

On the other hand, when the anchor bolt 8 is fixed, the sheath tube 3
An embedded nut 5 is provided on the foundation 2 near the base 2, and the level adjusting bolt 6 of the housing unit 1 is screwed to the embedded nut 5 at a predetermined height.

[Problems to be Solved by the Invention] As described above, the conventional level adjusting bolt 6 has the foundation 2
Since it is designed to be screwed into the embedded nut 5 of
When the foundation 2 was built, the embedding nut 5 had to be embedded in the foundation 2 at the same time, which took time and work efficiency was lowered.

An object of the present invention is to provide a grouting shield material that can be easily provided with a mounting member for a level adjusting bolt.

[Means for Solving the Problems] The present invention provides a shield material for grouting that is disposed on the upper surface of a foundation of a building so as to surround the upper end opening of a sheath tube embedded in the foundation. The feature is that the mounting member of the level adjusting bolt is fixed.

As for the mounting member of the level adjusting bolt, as long as the female screw portion is carved, the nut itself, the one in which the nut is fixed to the mounting piece, the one in which the female screw portion is carved into the mounting piece, etc. You can choose.

[Operation] Since the mounting member of the level adjusting bolt is fixed to the shield material main body, the mounting member of the level adjusting bolt is provided on the foundation at the same time when the shield material for grouting is arranged on the foundation. The work of installing the mounting member becomes unnecessary, which helps improve work efficiency.

[Embodiment] An embodiment of the present invention will be described with reference to FIG.

The grouting shield material 11 according to this embodiment is a sheath tube embedded in a foundation 12 when a unit house is assembled.
It is provided around the upper end opening of 13.

This grouting shield material 11 includes a shield material body 14 that surrounds the vicinity of the sheath tube 13 in a quadrangular shape, and a mounting member 17 for a level adjustment bolt 16 that is fixed to one corner 15 inside the shield material body 14. Composed.

The shield material main body 14 has a width and a height capable of sufficiently blocking the grout material flowing out from the sheath tube 13.
The material should have appropriate elasticity so as not to interfere with level adjustment and to prevent the grout material from being deformed. For example, sponge is preferable.

The mounting member 17 of the level adjusting bolt 16 is made of a rectangular metal member, and a female screw portion (not shown) into which the level adjusting bolt 16 is screwed is cut in the center thereof.
The mounting member 17 is fixed to one corner portion 15 inside the shield material main body 14 with an adhesive or the like.

Such a grouting shield material 11 is used as follows in assembling a unit house.

First, in the foundation 12 building process, the sheath tube 13 is embedded in the foundation 12 on which the anchor bolts should be installed at the same time as the foundation 12 is constructed.

Next, in the step of burying the anchor bolt attached to the bottom of the housing unit in the sheath tube 13, the grouting shield material 11 of the present embodiment is bonded onto the foundation 11 so that the sheath tube 13 is located at the center. To do. By providing the shield material 11 on the foundation 12, the mounting member 17 of the level adjusting bolt 16 fixedly provided on the shield material 11 is also provided on the foundation 12. Then, the level adjusting bolt 16 is screwed into the female screw portion of the mounting member 17 to adjust to a predetermined height.

Next, after pouring grout material made of, for example, cement mortar into the sheath tube 13, the housing unit is lowered while the anchor bolts of the housing unit lifted by a crane are embedded in the grout material. The housing unit is positioned at a predetermined height when the bottom of the housing unit comes into contact with the level adjusting bolt 16, and then the lower part of the anchor bolt is embedded in the sheath tube 13 by hardening the grout material.

According to the grouting shield material 11 of this embodiment, since the mounting member 17 of the level adjusting bolt 16 is fixed to the shield material body 14, the grouting shield material 11 is arranged on the foundation 12 and at the same time the level adjusting bolt is arranged. 16 mounting members
17 will also be provided in Foundation 12. Therefore, it is not necessary to separately provide a mounting member for the level adjusting bolt on the foundation 12 such as an embedded nut, which helps to improve the efficiency of the assembly work of the unit house.

In addition, since the grouting shield material 11 can be manufactured simply by fixing the mounting member 17 of the level adjusting bolt 16 to the shield material body 14, the grouting shield material 11 can be manufactured easily and can be provided at low cost.

In the above-mentioned embodiment, the mounting member for the level adjusting bolt has a female mounting portion into which the level adjusting bolt 16 is screwed, which is cut in the center of the metallic mounting member 17. It is optional, and may be, for example, the nut itself, or the one in which the nut is fixed to the mounting piece.

[Advantage of the Invention] According to the shielding material for grouting according to the present invention, the mounting member for the level adjusting bolt can be easily provided on the base.
