DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partial cross-sectional view of a solid foundation in this embodiment. 1 is a base member, 2 is an anchor bolt inserted into a plurality of bolt holes provided in the base member 1 in a vertical direction, and the upper end is fixed by a nut or the like. Reference numeral 3 denotes a support block attached to the lower end of the anchor bolt 2 and placed on the ground work surface, 4 denotes slab concrete cast to the height of the lower surface of the base member 1, 6 denotes an outer form, B denotes crushed stone, G Denotes a ground, and P denotes a support plate laid horizontally on a ground work surface.

It is desirable that the support block 3 be as small as possible in order to reduce the manufacturing and transportation costs and improve the workability. In the case of stability, a stabilizer wider than the bottom surface may be suitably attached to the lower surface of the support block 3 by bolting or the like so as to prevent falling. The stabilizer is a PC board, a metal board, a wood board, a resin board, or the like.

Next, the construction procedure will be described. Base member 1
Is an elongated member such as a timber or a C-shaped lightweight steel frame having a plurality of vertical bolt holes at predetermined intervals. The upper end of the anchor bolt 2 is inserted into the bolt hole and fixed to the base member 1 with a nut or the like. A support block 3 is attached to the lower end of the anchor bolt 2 by screw connection or concrete pouring.

FIG. 2 shows an example of a state in which the anchor bolt 2 and the support block 3 are attached to the base member 1. Needless to say, the base member 1 is configured to have a predetermined height in a state where the support block 3 is placed on the ground surface or the support plate P thereon. FIG. 3 is a partial sectional view showing a lower portion of the anchor bolt 2 and the support block 3. (A)
Is an insert nut on the upper surface of the support block 3.
The lower portion of the anchor bolt 2 is screwed into the thread portion of the insert nut 31, and the two are screwed together. On the other hand, the one shown in FIG.
A concave portion 32 is formed on the upper surface of the anchor bolt 2, and a lower portion of the anchor bolt 2 is inserted therein. In this case, although the two are not connected, the anchor block 2 and the upper base member 1 can be supported by the support block 3. Further, the mortar or the like may be poured into the concave portion 32 and the anchor bolt 2 and the support block 3 may be connected in advance.

FIG. 4 is a perspective view showing the support block 3. That is, the support block 3 may be in the shape of an elongated square bar so as to support a plurality of anchor bolts corresponding to the upper base member 1 as shown in FIG. It may be in the form of a die supporting each anchor bolt. Both can be prepared at the same construction site, and can be appropriately selected and used.

Since the support block 3 only needs to be able to support the base member until the slab concrete is cast, the material is not particularly limited. For example, ordinary concrete, lightweight concrete, metal plate, wood, resin or a combination thereof is used. It is. When the anchor bolt 2 and the support block 3 are connected in advance, the foundation member 1 is placed on a ground plane corresponding to the foundation of the building, that is, the ground is cut off and crushed stone is laid, and the ground plane is set at a predetermined level. , An anchor bolt 2 and a support block 3 are mounted. When the support block 3 is not attached to the lower end of the anchor bolt, the support block 3 is arranged on the ground work surface corresponding to the foundation of the building, and the base member 1 and the anchor bolt 2 are integrated. Is placed on this. In particular, when the support block 3 is a dice-shaped one, instead of disposing them directly on the ground work surface, a support plate P such as a fiber-containing concrete plate is laid on the ground work surface, and is arranged thereon. It is more preferable if it can be stably supported.

When these arrangements are completed, the slab concrete 4 is poured into a portion surrounded by the base member 1 on the outer periphery of the building, that is, at least the height of the lower surface of the base member 1 with respect to a range serving as a foundation of the building. . An outer mold frame 6 is used for the outer peripheral portion as appropriate. In this way, both the concrete foundation of the conventional cloth foundation and the solid foundation inside thereof can be cast simultaneously. It is desirable to arrange vertical and horizontal slab streaks as needed in the slab concrete portion.

FIG. 5 shows a base member 1 and anchor bolts 2,
FIG. 9 is a partial perspective view showing a state where a combination of three members of the support block 3 is arranged in advance. This figure shows a portion connecting a partition base member 1b before the outer peripheral base member 1a, but these base members 1a and 1b do not necessarily need to be connected to each other. Generally, the base member 1
Although (1a, 1b) are arranged at the same level, the support blocks 3 do not necessarily have to be at the same level as in other embodiments to be described later.

The concrete of the solid foundation portion in this embodiment is thicker than the conventional general solid foundation. Therefore, although the amount of concrete used will increase, the insulation,
It has excellent advantages such as increased moisture resistance and insect repellency such as ants, and has a large heat storage effect, so that it has excellent advantages such as low energy consumption and is more economical. In addition, it is also possible to reduce the amount of concrete used by appropriately embedding a foam resin box or the like in a portion where the base member 1 is not provided.

Embodiment 2 FIG. 6 is a partial cross-sectional view of a solid foundation showing a second embodiment of the present invention. The difference from FIG. 1 is that the load on the partition portion is relatively light, and The ground work of the solid foundation is higher than that of the outer periphery, for example, the surrounding ground (G.
L.), and the amount of excavation and cast concrete is reduced.

In this case, if the thickness of the slab concrete at the partition is about 200 mm, a commercially available concrete block (standard height: 190 mm) can be used as the support block 3a for the partition as shown in FIG. is there. FIG. 7 is a perspective view showing a state where the support block 3a is attached to the base member 1b via the anchor bolt 2. Fine adjustment of the height is performed by inserting a shim 33 between the support block 3a and the base member 3b. FIG. 8 is a partial sectional view of the solid foundation in this case. The same as the support block 3a for the partition may be used as the support block 3 in the outer peripheral portion,
It may be another. 5 is a slab muscle.

FIG. 9 shows still another example of the support block. The support block 3b is a hollow concrete block whose both sides are open. A hole is made in the center of the top, an anchor bolt 2 with a long nut 21 attached to the tip is inserted into the inside, and the long nut 21 is rotated to extend the entire inside of the support block 3b. If the auxiliary bolts of both screws are screwed into the long nut 21 from above in alignment with the hole at the center of the top, the same thing as the conventional support block can be obtained. Since the support block 3b is hollow, it can be passed through when the slab streaks are arranged later. It is also light to carry. The same thing can be made of a metal plate.

Embodiment 3 Next, unlike the previous embodiments, a preferred construction method of a solid foundation in a case where a base member is not pre-attached to an anchor bolt will be described. Long nut 21 on top of anchor bolt 2
Is screwed, and on the thin plate corresponding to the plane dimension of the base member, a measuring plate 15 provided with a plurality of bolt holes at anchor bolt positions is mounted, and the temporary bolt 22 is screwed into the long nut 21 from above and tightened. For example, as shown in FIG. 10, the construction is the same as that of the anchor bolts with the base shown in FIGS. . After the concrete hardens, loosen the temporary bolt 22 to remove the scale plate 15, and attach the auxiliary bolt 23 having both ends threaded to the long nut 21 as shown in FIG.
Into the base, and the base member can be attached.

Embodiment 4 FIG. 12 is a partial sectional view showing an outer peripheral portion of a solid foundation according to a fourth embodiment of the present invention, and FIG. 13 is a partial sectional view showing a partition part, and 61 is parallel to the base member 1. The top is a weir frame arranged at a height corresponding to the lower surface of the base member 1 (1a, 1b). As shown in FIGS. 12 and 13, the slab concrete 4 is filled up to the lower surface of the base member 1 only on the inside of the weir frame 61, that is, only on the base member 1 side. Only the lower surface of the dam frame 61 is cast. In this way, the work of filling the most important lower surface of the base member 1 with concrete can be performed easily and reliably, and the amount of concrete to be poured is reduced as long as the predetermined slab thickness is secured. it can. Therefore, the distance between the base member 1 (1a, 1b) and the weir frame 61 is
The concrete filling work should be performed easily. The weir frame 61 may be temporarily fixed and supported from the base member 1 (1a, 1b).

In this solid foundation, a gap corresponding to the height of the weir frame 61 is formed between the base member 1 and the slab concrete 4 inside the foundation, so that it is convenient to perform piping and wiring under the floor. The weir frame 61 is removed in principle after the concrete has hardened. Fifth Embodiment FIG. 14 is a partial cross-sectional view showing an outer peripheral portion of a solid foundation according to a fifth embodiment of the present invention, in which a heat insulating material 62 is provided on the outer surface of the foundation, that is, on the outside of a base member or a scale plate arranged on the outer peripheral portion. The PC block 63, which is a concrete block made of PC, is disposed vertically outside the heat insulating material 62.
And the PC block 63 is used to hold the slab concrete 4. PC block
63 is connected appropriately in the longitudinal direction of the foundation, but is fixed to the ground by its own weight. Therefore, it is desirable to lay the support plate P on the lower surface for stability.

Embodiment 6 FIG. 15 is a partial cross-sectional view showing an outer peripheral portion of a solid foundation in a sixth embodiment of the present invention, where 6 is an outer mold, 7 is a mold holder for holding the outer form, and 12 is Base member 1 and form holder 7

That is, in this embodiment, the outer formwork 6 is pressed from outside by the form retainer 7 locked to the base member 1, and the slab concrete 4 is cast by fixing the pile reinforcing bar 73 at the lower portion on the inside. . As the outer mold frame 6, a wooden damping plate or a metal damping plate generally used in the related art may be used, but a veneer plywood generally referred to as a "control panel" is preferable.

FIG. 16 shows an example of the form holder 7. (A) is a lattice reinforcing bar 71 in which reinforcing bars are formed in a lattice shape, and (b) is a columnar reinforcing bar 72.
In each case, drive the vertical reinforcing bar into the ground and fix it.
The outer formwork 6 is pressed by a horizontal reinforcing bar. Seventh Embodiment Next, FIG. 17 is a partial perspective sectional view showing a modified embodiment of the base member 1. Reference numeral 11 denotes a spacer having a constant thickness and wider than the base member 1. FIG. The material of the spacer 11 is not particularly limited, but is preferably an easy-to-handle and inexpensive material such as a foamed resin. Spacers 11 are attached to the lower surface of the base member 1 at predetermined intervals as shown in FIG. At least the lower part of the base member and the periphery of the spacer 11 are cast with the slab concrete 4 up to the lower surface of the base member 1 and, after hardening, the spacer 11 is removed, as shown in FIG. A vent hole V is formed. (C) is the AA in (b)
It is sectional drawing of a sight. The vent hole V is characterized in that the air flow from the outside once hits the concrete inside the base, turns 90 degrees and is blown upward, so that there is no blow-through and the wind pressure is reduced. The ventilation holes V can be appropriately installed as needed on any base of the outer peripheral portion and the partition wall.

When the ventilation hole V is provided on the outer peripheral portion, it is necessary to attach a rat-proof member 14 to the opening of the ventilation hole V so that a small animal such as a mouse does not enter. An example is shown in FIG. This figure is a partial perspective view showing the vicinity of the ventilation hole in the outer peripheral portion, in which 14 is a rat-proof member, and 13 is a support bracket hanging from the base member 1. Assuming that the opening between the base member 1 and the slab concrete 4 is 20 mm in the vertical direction,
As a rat-proof member 14, a stainless steel rod having a diameter of 5 mm may be hung horizontally at almost the middle height.

FIG. 19 is a partial perspective view showing the vicinity of the ventilation hole V in the other outer peripheral portion. The slab concrete 4 inside the outer peripheral portion is lowered by the weir frame as described in the fourth embodiment. Vent straight V in the high part just below 1

The slab concrete 4 is cast and the slab concrete 4 extends only to the lower surface of the base member 1 for a part. By doing so, the floor can be made by directly attaching a flooring material to the surface of the high portion, and the pipe, wiring, etc. can be passed through the low portion.

In each of the embodiments described above, the vertical and horizontal slab streaks are appropriately arranged in the middle slab concrete portion of the base member. A preferred method of arranging the slab streaks will be described with reference to FIGS. 21 to 23. . The horizontal spacing of the slab streaks is preferably 150 to 200 mm. FIG. 21 is a perspective view showing the reinforcing bar support 8, in which U-shaped grooves 82 are formed on the upper surface of a square rod-shaped main body 81 at the above intervals. If the reinforcing bar support 8 is placed at an appropriate position on the ground work surface, and the reinforcing bars are arranged so as to fit into the grooves 82, the slab bars are arranged at predetermined intervals.

FIG. 22 shows a reinforcing bar support 8a in which slab bars are arranged in two upper and lower stages. The main body 81 is substantially the same as that of FIG. 21 including the groove portion 82, except that an appropriate hole is provided in the middle of the groove portion 82, and a reinforcing bar support metal 83 for supporting the upper reinforcing bar is attached. The U-shaped hardware corresponding to the groove 82 is arranged on the reinforcing bar support 83 at the above-mentioned interval. It is preferable that the reinforcing bar support 83 be attached and detached so that the upper bar is arranged after the lower bar is finished.

The upper reinforcing bar is suspended from the reinforcing bar fixing metal 24, and the lower reinforcing bar is supported by the reinforcing bar supporting metal 25. . By doing so, it is possible to efficiently arrange the reinforcing bars using the frame-shaped reinforcing bars 53 manufactured in advance in the factory.

[0035]

According to the present invention, since the concrete on the cloth foundation and the solid foundation can be poured at the same time, not only the efficiency of concrete construction can be improved, but also when the base member is pre-attached to the anchor bolt, the anchor bolt and the base member can be used. Since the combination with the steel is completed at the same time, the construction period of the foundation work is shortened, which is an excellent effect. In addition, since the thickness of the solid base portion is increased, there are excellent advantages such as increased heat insulation, moisture resistance, and insect repellency such as ants, and a large heat storage effect, resulting in low energy consumption.
