Description

[Detailed description of the invention] Industrial applications The present invention relates to a column base device for a house.

Conventional technology Fig. 7 shows the structure of a conventional column base in a prefabricated house with a frame structure, in which an anchor bolt (52) is projected onto a concrete foundation (51). , fixing the frame base (53). (54) is the pillar of the framework (55). and,
An outer wall plate and an inner wall plate are respectively attached to the outer and inner surfaces of the frame assembly (55) attached in this manner.

In a column base with such a structure, the base at! (51)
It has a structure in which the and frame (55) are directly connected to each other, and as a result, shaking during an earthquake is transmitted directly from the ground to the frame (55) through the foundation, making it susceptible to earthquake damage. In addition, if a hole for an anchor bolt (52) is previously provided on the base (53) side, the positional accuracy of the anchor bolt (52) can be adjusted by checking the foundation concrete (51) in order to align with this hole. The drawback is that it must be taken out at the time of setup, and it is extremely difficult to ensure accuracy. In addition, if the entire building sinks unevenly, the anchor bolt (52) (56)
It is necessary to loosen the and lift the frame (55) side,
When the building is completed, this Natsu} (56)
is blocked by the above-mentioned outer wall board or inner wall board, which is inconvenient in that the outer wall board or inner wall board must be partially destroyed.

Therefore, the inventors of this application have solved these drawbacks by fixing a base having a U-shaped cross section on a concrete foundation with anchor bolts, and further fixing a framework to the upper part of the base with bolts. He invented the
It was announced as No. 28.

Problems to be Solved by the Invention According to the invention disclosed in the above-mentioned publication, the foundation concrete and the framework are not directly connected, and the shaking during an earthquake can be absorbed to a certain extent, and furthermore, the position of the anchor bolt is not necessarily determined with high precision. This is not necessary, or there is an advantage that the base can be lifted directly by inserting a jack or the like into the opening of the base. However, in such a structure, the framework, that is, the entire building, is supported only by the U-shaped cross-sectional foundation, so the thickness of this foundation must be thickened to provide sufficient strength. However, there was a drawback that the overall cost was high.

The object of the present invention is to provide a footnote device for a house that uses a foundation having a U-shaped cross section and can be implemented at a low cost overall by reducing the cost of the foundation.

Means for Solving the Problems In order to achieve the above object, in this invention, a base having a U-shaped cross section is placed on the foundation, the lower piece thereof is fixed with an anchor bolt protruding from the foundation, and the lower piece is also placed on the upper piece. The frame assembly and the upper piece are fixed to each other, and load-bearing members are provided between the upper piece and the lower piece, respectively, corresponding to the column parts of the frame.

Furthermore, in the above, the load-bearing member interposed between the upper piece and the lower piece may be a load-bearing bolt, a load-bearing box, or the like.

The strength of the working foundation only needs to be ensured in the column parts; therefore, by providing load-bearing members in these parts, the entire foundation can be made of thin materials such as lightweight thin plates.

Effects of the Invention As described above, according to this invention, in addition to the effects of the invention of Japanese Patent Publication No. 61-27528, which uses a base having a U-shaped cross section like the present invention, Since load-bearing members such as load-bearing boxes and bolts are installed, it is possible to sufficiently support the load of the building with these load-bearing members, and the foundation itself can be made of inexpensive materials such as lightweight thin plates. It has the advantage that it can be implemented at low cost. In this case, if a box-shaped load-bearing member is used, it will be somewhat expensive due to its manufacturing cost, but if a load-bearing bolt is used, it can be manufactured at a lower cost. Also, it is possible to provide the foundation only at the position corresponding to the column, for example, but in that case,
There is nothing to connect the lower end of the frame to the wall, which makes it weak in strength. However, in this invention, the foundation is placed around almost the entire circumference of the building, so this disadvantage can be avoided. You can get something with high strength.
