[0002]

2. Description of the Related Art Conventionally, in molding a foundation of a general house, a technique of integrally forming a base portion and a frame supporting portion into an inverted T-shape has been known. It is also known that the frame of the frame supporting portion is made of metal foam and the base frame is made of a resin plate.

[0003]

Conventionally, the base frame portion has a concrete poured into the inside thereof, which is pushed open by the blowing force, and the concrete squirts from the portion to make the shape of the base portion irregular. There was a problem that the strength of the part was reduced. The present invention solves such a problem and provides a mechanism for fixing the base frame to the lower part of the metal foam.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. In claim 1, the base is downward.

[0006]

Next, the operation will be described. That is, even when the embankment D is not formed on the upper surface of the base frame 3 as in the related art, the gap between the base frame 3 and the metal foam 4 is removed and the fresh concrete C does not blow out. Therefore, since the foundation can be formed without the embankment, the work of backfilling the embankment D and finally excavating again to remove the base frame 3 can be omitted. Further, the holding plate 2 and the base frame 3 can be easily fixed to the metal form 4 simply by inserting the holding metal fitting 1 between the vertical rail 8 and the holding plate 2. Since the presser fitting 1 is simply inserted between the vertical rail 8 and the presser plate 2, it is easy to remove and attach it, and it can be performed by an unskilled person. Further, when there is a U-shaped fastener 5 in a portion where the metal form 4 is adjacent, the U-shaped fastener 5 can be jointly fastened by the U-shaped fastener 5. Therefore, the presser fitting 1 can be omitted in this portion.

Cross-sectional view of a normal integral molding base, Fig. 1
0 is an integrated foundation when the embankment D of the base portion A is small, and is a cross-sectional view of a state where the embankment D is fixed by the presser fitting 1 and the presser plate 2 of the present invention. FIG. FIG. 12 is a sectional view showing a state in which concrete has blown out.
Are the horizontal rail 7 of the metal foam 4, the upright edge 9, and the base frame 3.
FIG. 4 is a cross-sectional view showing a relative position between the press plate 2 and the pressing plate 2.

[0008] In a normal integrated foundation, as shown in FIG. 9, a base portion A is often disposed underground,
The embankment D is filled with the base frame 3 set, and the base frame 3 is pressed against the lower part of the metal foam 4. Therefore, when concrete is poured from the upper part of the metal foam 4, the embankment D Since the pressing force presses the base frame 3 against the lower part of the metal foam 4, even if the concrete blowing force acts from inside the base frame 3, the base frame 3 does not come off and the concrete does not blow out.

However, recently, there is a case where the embankment D is small. In such a case, as shown in FIG. 11, the embankment D hung on the base frame 3 is small and the upper half of the base frame 3 is exposed. It becomes. When the ready-mixed concrete C is cast in this state, the metal foam 4 is firmly fixed, so there is no blow-out part. However, the base frame 3 is placed between the metal foam 4 and the lower part and the soil surface. In many cases, when the blowing force of the concrete acts on the portion, there is a problem that the concrete blows out from between the lower part of the metal foam 4 and the upper part of the base frame 3. is there. As a result of the concrete being blown out from the base frame 3, the appearance of the portion of the base portion A deteriorates, and a gap is formed inside the base portion A to cause a portion having a low strength. . In the present invention, as shown in FIG. 10, a presser fitting 1 for fixing the upper portion of the base frame 3 to the metal foam 4 is provided to solve the problem shown in FIG. Metal foam 4
The pressing plate 2 is configured to press a part in the middle so as not to come off.

Referring to FIG. 1, a description will be given of an integral molding structure in a house foundation. Fresh concrete C is injected between the metal foams 4 from the concrete injection pipe 6.
The metal form 4 is made of an iron plate, and the metal form 4 between the adjacent metal forms 4 can be simply fastened and fixed by a U-shaped fastener 5. The metal form 4
It is placed and fixed on a metal foam mounting table protruding from the reinforcing bar structure, and the lower part of the fixed metal foam 4 is opened, so that the ready-mixed concrete C is injected downward from between the metal foams 4. Then, the base portion A flows to the portion of the base frame 3 that closes the side, and the portion stopped by the base frame 3 constitutes the base portion A.

The base portion A is usually buried in the soil because the embankment D is formed thereon, and is a portion whose appearance is not so pointed out. Normally, since the base frame 3 is buried and killed, there is no problem even if the fresh concrete C blows out so much. However, recently, the hourly wage of construction workers has risen,
Because of the tendency to dislike operations such as the transportation of earth and sand, the tendency to omit the operation of embankment D after laying the base frame 3 has increased. In particular, in the housing foundation, the outer part of the outer wall foundation is easy to move the carrier, so that the embankment D on the base frame 3 is relatively easy. In the part, the outer wall foundation is in the way, so with the metal form 4 set,
This made it impossible for vehicles and unicycles to pass, making it impossible to transport earth and sand for embankment D. For this reason, the entire base frame 3 is not buried under the embankment D, and the fresh concrete C pushes up the base frame 3 and blows out as in the conventional problem.

The present invention provides a base frame 3 which does not come off with the metal foam 4 even if there is no embankment D in order to solve such a problem of the prior art.
In order to achieve the object, first, it is necessary to press and fix the base frame 3 on the horizontal rail 7 below the metal foam 4.
After the upper end of the plate is placed, the presser plate 2 is placed thereon and fixed. The holding plate 2 is shown in FIGS. 5, 6 and 7. First, in the embodiment shown in FIG. 5, the holding plate 2 is used for the linear portion of the metal foam 4, and has a vertical rail recess 2b through which the vertical rail 8 of the metal foam 4 can pass. In addition, presser foot 1
A long hole 2a for engaging with the engaging projection 1a at the lower end is formed. In the holding plate 2 for the straight portion,
Since there is no fixed portion by fastening fitting 5 of the U-shaped fastening bracket clamping piece 2c is not been configured.

In FIG. 6, a holding plate 2 is used at a portion near an outer corner or an inner corner. In this portion, a joining portion of a metal foam 4 is present, and a fastening portion is provided by a U-shaped fastening fitting 5. Therefore, a fastening fitting holding piece 2c is formed on the holding plate 2, and a U-shaped fastening fitting 5 is formed between the adjacent metal forms 4.
At the time of fastening, the clamp 2 is fastened together with the U-shaped fastener 5 to fix the holding plate 2. Even in the state of being fixed by the U-shaped fastening member 5, the locking projection long hole 2a is provided so that the holding member 1 can be interposed. In FIG. 7, the holding plate 2 is used at a special inner corner portion, and fastening metal clamp pieces 2 c are provided at four places. FIG. 8 shows a configuration of the holding fixture 1. The holding fitting 1 has a lower end provided with a locking projection elongated hole 2 a provided on the holding plate 2.
To prevent displacement, the upper part constitutes a bent part 1b, and the bent part 1b is pushed under the upper horizontal bar 7 so that the presser fitting 1 does not come off due to elastic force. Make up.

As shown in FIG. 12, an upright edge 9 is slightly erected at the lower end of the metal foam 4 at the end of the cross bar 7, so that the upper end locking portion 3a of the base frame 3 is It is placed obliquely in such a configuration as to be hooked on the upright edge 9. Upper end locking portion 3 of base frame 3 hooked on standing edge 9
A holding plate 2 having a key-shaped cross section with a downward edge portion 2d bent is further placed on the portion a. Therefore, a gap is generated between the holding plate 2 and the horizontal rail 7, so that it is possible to insert the portion of the locking projection 1a of the holding metal fitting 1 toward this portion, and the displacement of the holding plate 2 is reduced. It can be blocked.

[0015]

As described above, the present invention has the following advantages. With the configuration as in claim 1, even when the embankment D is not formed on the upper surface of the base frame 3 as in the related art, the gap between the base frame 3 and the metal foam 4 is removed, and the fresh concrete C does not blow out. . Therefore, since the foundation can be made without the embankment, the work of backfilling the embankment D and finally excavating again to remove the base frame 3 can be omitted. Further, the holding plate 2 and the base frame 3 can be easily fixed to the metal form 4 simply by inserting the holding metal fitting 1 between the vertical rail 8 and the holding plate 2. Since the presser fitting 1 is only inserted between the vertical rail 8 and the presser plate 2, it can be easily attached and detached and can be performed by an unskilled person.

According to the second aspect of the present invention, if there is a U-shaped fastener 5 in a portion where the metal foam 4 is adjacent, the U-shaped fastener 5 can be used for joint fastening. Therefore, the presser fitting 1 can be omitted in this portion.
