Description

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

Conventional technology Figure 11 shows the structure of a conventional column base in a prefabricated house with a frame structure.
An anchor bolt (52) is made to protrude upward, and the base (53) of the framework is fixed by this anchor bolt (52). (54) is the pillar of the framework (55). Then, outer wall plates and inner wall plates are respectively attached to the outer and inner surfaces of the frame assembly (55) attached in this manner.

In the column base of such a structure, the foundation (5l) and the frame (55) are directly connected to each other, so the shaking during an earthquake passes from the ground through the foundation to the frame (55).
) side, it has the disadvantage of being susceptible to earthquake damage. In addition, if a hole for the anchor bolt (52) is previously provided on the base (53) side, the positional accuracy of the anchor bolt (52) can be adjusted to match the basic 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, loosen the nut <<56>> of the anchor bolt (52),
It is necessary to lift the ring (55) side, but when the building is completed, this nut <<56>> is covered by the above-mentioned external wall board and internal wall board. There is an inconvenience that it is necessary to partially destroy the

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 foundation, so the thickness of this foundation must be increased 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 column base device for a house that uses a U-shaped foundation in 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, an angular plate having a plurality of bolts projecting upwardly is fixed on a foundation with anchor bolts projecting from the foundation, and a cross-sectional fixing the lower piece at each connecting end of the U-shaped base onto the square plate by each bolt of the square plate;
Similarly, a framework placed above the base is fixed with bolts to the upper part of the framework, and a load-bearing member is provided between the upper and lower pieces in the part corresponding to the column of the framework. do.

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 metal fitting, or a combination thereof.

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

Embodiment FIGS. 1 to 3 show a first embodiment of the present invention. In those figures, 《l》 is the pace part 《2》 and the cloth part (

Since the lower piece (10) can be brought into close contact with the lower piece (10), it is possible to reliably support the base (5) even if there is a dimensional error, for example, unlike the previous embodiment. Further, each load-bearing bolt <<44>> is attached to the load-bearing metal fitting <<l2>> in advance, and the whole is brought to the site in a unified state, which has the advantage of facilitating parts management.

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. Furthermore, in this invention, since the bases are connected to each other by the corner plate, it is possible to obtain a device that also serves as a connection between the bases.
