Description

[Detailed description of the invention] A. Purpose of the invention (a) Industrial application field This invention is intended to provide a foundation for raising the height of a wooden building with a new configuration.

(b) Conventional technology and its problems When a wooden building is deformed due to changes in the water level of groundwater due to water and sewage construction, road construction, or ground subsidence due to soft ground, etc., the foundation and foundation (shelter) are integrated as in the past. It is difficult to separate the foundation from the base of a structure that has a flat structure, and since the base is made of wood, it is unstable and expensive when separated from the foundation.

Since the foundation is made of wood, the deformation of the foundation is directly transmitted to the upper house.

There were problems such as.

B. Structure of the invention A. Means for solving the problem The present application attempts to solve the above-mentioned problem with the following structure.

That is, in the present application, a base body 3 made of steel is disposed on the upper surface of the base 2, and lateral slip prevention plates inscribed on the inner surface of the base are attached at predetermined intervals to the inner surface of the base body. At the same time, metal fittings for connection with the foundation are provided on the lower surface of the foundation body at positions corresponding to the front square notches 2A carved at predetermined intervals on the upper surface of the foundation 2, and This foundation for raising the height of a wooden building is provided with a joist support for suspending and fixing a joist on the inside surface, and a hardware for fixing the lower end of a column on the upper surface of the base body.

In this case, the cutout portion 2A can be a front square cutout for attaching a ventilation hole.

B. Example 1 of the invention is a raised foundation for a wooden building according to the invention. 2 is a known foundation, and 3 is a base body disposed on the upper surface of this foundation, which includes vertical members 3A and horizontal members 3B made of rectangular cylindrical steel members, and an outer frame portion 3C connected in a rectangular plane. It is composed of a reinforcing material 3D stretched appropriately within this outer frame portion 3C.

3E is a box-shaped metal fitting attached to the lower surface of this base body 3 at a predetermined interval for connection with the foundation 2, and includes a horizontal part 3E' and both walls 3E'' folded at both ends of this horizontal part. A small hole through which the anchor bolt 7 passes is bored in the horizontal portion 3E'.

The installation position of this box-shaped hardware 3E is the foundation 2.
It can be attached so as to correspond to the square cutout portions 2A cut out at predetermined intervals on the front surface.

In this case, the cutout 2A may be a front square cutout for mounting a known ventilation hole attached to the foundation 2.

3F is a lateral slip prevention plate attached to the outer frame 3C and, if necessary, to the inner surface of the reinforcing material 3D, and the lower portion 3F' is a plate below the lower end of the outer frame so that it can be inscribed on the inner surface of the foundation 2. It is in a state of protrusion.

Reference numeral 4 denotes a well-known joist horizontally suspended within the outer frame portion 3C and reinforcing material 3D, and both ends of the joists are connected to the outer frame portion 3.
It is supported by a box-shaped joist support 3G fixed to the inside of C and the reinforcing material 3D so as to face each other.

This joist support 3G is composed of both walls 3G'' that stand up at both ends of the horizontal portion 3G'.
A nail hole is drilled in G″.

5 is a pillar to be planted on the foundation, and this pillar is a support 3H consisting of a pair of walls 3H', 3H' having nail holes protruding from the outer frame and the upper surface of the reinforcing material.
The lower end of the pillar 5 is fixed by nailing.

6 is used when connecting the vertical members 3A and the horizontal members 3B in the outer frame part in a planar L shape, or when the reinforcing member 3 is attached to the outer frame part.
Plane L used when connecting D into a plane T shape
It is a type of connecting hardware.

C Effect I will explain it along with the effects.

C. Effects of the invention (a) Even if a wooden building is tilted due to ground subsidence or the foundation is destroyed, the raised foundation is placed on top of the foundation, so the raised foundation can be raised using a known method. Repair work can be carried out on the foundation part without affecting the wooden building on the raised foundation while being supported by the method.

Moreover, this repair work can be carried out safely in a short construction period.

In addition, as mentioned above, even if the foundation is destroyed or tilted due to ground subsidence, the wooden building on the raised foundation is less likely to be damaged.

(b) Since a raised foundation, which is a steel structure, is used for the foundation, the so-called foot of the wooden building becomes strong, and it is possible to better fit external walls, window frames, etc.

C. The strength of the foundation can be improved because it uses a raised foundation that is a steel structure.

In other words, since it is a steel structure, the deflection, strength, etc. can be calculated and used according to the wooden building, so it can be used not only as a foundation but also as a structure.

D. Since the lateral slip prevention plates inscribed in the inner surface of the foundation are attached at a predetermined interval to the inner surface of the foundation main body, the foundation main body will not shift from the foundation.

E. Since the joist supports are provided, the joists can be installed easily and reliably.

F Since the upper surface of the above-mentioned foundation body is provided with hardware to fix the lower end of the column, the following effects can be expected.

During on-site construction, steel structures and wooden columns do not fit together well, but this hardware allows the columns to be easily and reliably connected.
