[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an architectural foundation installed on the ground to support a building, and a foundation block used for the construction.

[0002]

[Prior art]

 The work of building the foundation on the ground is very important for buildings. Of these foundations, cloth foundations are often created for ordinary houses. Although there are I-shaped and inverted-T cross-sections of the fabric foundation, it is preferable to use the inverted T-shaped in order to withstand a large load. The widened bottom surface of the inverted T-shaped fabric base is called a footing, and a portion which is vertically raised on the footing is called a rising portion.

[0003] The installation work of such a cloth foundation will be described below with reference to FIGS. It is necessary to embed anchor bolts on the cloth foundation to fasten the wood that will be the foundation of the building, but the explanation of this work is omitted. That is, first, as shown in FIG. 9, a root cutting operation for digging a groove 1 along a line for forming a fabric foundation is performed on the ground on which a building is to be built. Then, split rubble stones 2 are laid vertically on the bottom of the groove 1, and crushed gravel (not shown) for filling the gap is put. Further, the surface is compacted by a rammer as a compacting machine, a mortar kneaded with water is poured from above, and the surface is solidified so that the surface is horizontal, thereby forming the base 3. Complete the business.

Next, as shown in FIGS. 10 and 11, flat plate-shaped base frames 4 are vertically set on the left and right inner side surfaces of the groove 1, respectively. Then, the spacer block 5 having a substantially rectangular parallelepiped shape is appropriately arranged on the horizontal surface of the base 3, and the braided reinforcing bar 6 in which the horizontal reinforcing bar 6 a and the vertical reinforcing bar 6 b are welded or fastened by wire is placed thereon. . Further, as shown in FIG. 12, concrete is poured to the height of the base form 4 so that the lower part of the reinforcing bar 6 is embedded, and the footing 9a is solidified by leveling the surface so as to be horizontal. Create.

[0005] As shown in FIG. 13, two rising mold frames 7 are erected on both sides of a vertical reinforcing bar 6b protruding from the footing 9a. The upper portions of the two rising mold frames 7 are fastened by a plurality of spacers 8 so that the thickness of the rising portions can be secured. As shown in FIG. 14, concrete is poured into the rising formwork 7 assembled as described above and solidified to form a rising portion 9b on the footing 9a. Further, the concrete is cured for several days after the above-mentioned concrete casting, and when it is sufficiently hardened, the rising formwork 7 is removed and the soil is buried back so that the footing 9a is hidden, thereby completing the construction of the building foundation.

[0006]

[Problems to be solved by the invention]

 However, the architectural foundations created by the above procedure had the following points to be improved. That is, after the concrete of the footing 9a is cast, and after it is solidified, the rising form 9 is assembled and the concrete setting of the rising portion 9b is performed, so that the driving work is troublesome and the required time for forming the foundation is required. The days are longer.

In addition, since the raised portion 9b is formed on the surface of the footing 9a after the footing 9a is solidified, the integration of the surface of the footing 9a and the bottom surface of the raised portion 9b is not always sufficient. Then, since a certain degree of unevenness occurs on the joint surface between the footing 9a and the rising portion 9b, when a building is constructed on the rising portion 9b, the force applied to the footing 3 from the rising portion becomes uniform. Hateful.

[0008] Furthermore, the line on which the fabric foundation is formed is used below the outer peripheral wall of the building and the main partition wall, around a room using water such as a bathroom, and stands up. The positioning of the mold 7 must be performed accurately. However, it is difficult to determine the reference on the surface of the solidified footing 9a, and there are irregularities on the surface, so that accurate alignment is not always easy.

[0017]

[Embodiment of the invention]

 An embodiment of the foundation block and the building foundation of the present invention will be described below with reference to the drawings. In addition, about the same part as the prior art shown in FIGS. 9-14, description is partially simplified.

(1) Configuration of Basic Block First, the configuration of the basic block in the present embodiment will be described. That is, as shown in FIG. 1, the base block 10 is formed by integrally forming the main body 11 and the projections 12 by concrete. The main body 11 has a rectangular parallelepiped shape, and its longitudinal direction has a length corresponding to the width of the footing 9a. The protrusions 12 have a substantially rectangular parallelepiped shape, and two protrusions 12 are formed on the upper surface of the main body 10 at a predetermined interval. The lateral width of the upper part of the convex part 12 is formed longer than the lateral width of the lower part. Therefore, the opposing side surfaces of the two convex parts 12 are inclined upward and away from each other.

Here, the interval between the upper portions of the two convex portions 12 corresponds to the thickness of the rising portion 9b. The upper surface 12a of each convex portion 12 corresponds to the form setting portion described in the claims, and is a horizontal surface on which the rising form 7 can be placed. The upper surface 11a of the main body 11 other than the convex portion 12 corresponds to the reinforcing bar mounting portion described in the claims, and is a horizontal plane on which the reinforcing bar can be mounted. Further, inside the basic block 10, reinforcing bars 13 are embedded in the width direction of the main body 11 and the height direction of the projections 12.

The dimensions of the basic block 10 can be freely set. As an example, the dimensions can be designed as follows. That is, as shown in FIG. 2, the main body 10 has a height of 70 mm, a width of 450 mm, and a depth of 60 mm. The protrusion 12 has a height of 80 mm, an upper width of 70 mm, a lower width of 75 mm, and a depth of 60 mm. The interval between the upper portions of the convex portions 12 is 110 mm, the interval between the lower portions is 100 mm, and the length from both ends of the main body 10 to the two convex portions 12 is 100 mm.

(2) Creation of Architectural Foundation A procedure for installing an architectural foundation using the above-described foundation block 10 will be described below. That is, first, as in the conventional technology shown in FIG. Next, as shown in FIG. 3 and FIG. 4, flat base molds 4 are vertically set on the left and right inner surfaces of the groove 1, respectively. Then, a plurality of base blocks 10 are arranged at equal intervals on the base 3 between the base forms 4, and each of the base blocks 10 is provided with a horizontal reinforcing bar 6a and a vertical reinforcing bar 6b by welding or wire. Place the fastened rebar 6 on it. At this time, among the horizontal reinforcing bars 6a at the lower part of the braided reinforcing bar 6, the reinforcing bars 6a in the longitudinal direction of the footing 9a are placed on the upper surface 11a of the main body 11 of each base block 10. Deploy. Also, the reinforcing bar 6b is arranged so that the vertical reinforcing bar 6b protrudes upward from between the two convex portions 12.

Further, as shown in FIGS. 5 and 6, the rising formwork 5 is placed on the upper surface 12 a of each of the two convex portions 12 in each basic block 10. At this time, the thickness of the rising portion 9b is ensured by matching the position of the two rising mold frames 5 with the end of the upper surface 12a of the convex portion 12. The two rising mold frames 5 are fastened by a plurality of spacers 8. Then, as shown in FIG. 7, concrete is poured into the inside of the rising formwork 5 installed as described above to form the footing 9a and the rising portion 9b at one time. At this time, the amount of concrete poured is adjusted so that the height of the footing 9a is the same as the height of the convex portion 12 of the foundation block 10. When the concrete thus poured is sufficiently solidified, the rising formwork 5 is removed to complete the construction of the building foundation.

(3) Effects of the Embodiment The effects of the present embodiment as described above are as follows. That is, since the concrete casting of the footing 9a and the concrete casting of the rising portion 9b can be performed at one time, the number of days required for forming the building foundation is shortened. In particular, it is advantageous when the temperature is hard to solidify concrete or when it is desired to shorten the period of rent for rebuilding.

In addition, since the preparation for driving is completed only by arranging the plurality of basic blocks 10 and placing the rising formwork 7, the rising formwork 7 is driven rather than assembled on the already solidified footing 9 a. The work does not take much time and the burden on the workers is reduced.

Further, since the base blocks 10 can be arranged on the basis of the width of the base 3 or the interval between the base forms 4, each base block 10 can be positioned more accurately and quickly than the conventional spacer block 5. Can be arranged. Further, since the base block 10 disposed on the base 3 is held from the left and right sides by the groove 1 or the base form 4, the displacement is less likely to occur than the conventional spacer block.

In addition, since the work of placing the rising mold frame 7 can be performed using the end of the upper surface 12 a of the projection 12 as a guide or as a reference, accurate positioning becomes easy. In addition, since the upper surface 12a of the convex portion 12 is a horizontal surface without unevenness, the rising mold frame 7 is hardly displaced, and the rising mold frame 7 is easily detached. Further, since the height of the footing 9a may be based on the upper surface 12a of the projection 12, the concrete striking can be performed accurately.

Since the reinforcing bar 6a only needs to be placed on the upper surface 11a of the main body 11, the installation work of the reinforcing bar 6a is simplified. In particular, since the upper surfaces 11a for placing the reinforcing bars 6a are alternately arranged with the convex portions 12, alignment for securely embedding the reinforcing bars 6a and 6b in the footing 9a and the rising portions 9b is performed. It can be done easily.

Further, since the footing 9a and the rising portion 9b can be completely integrated without a joining surface, excellent strength and durability can be obtained. Since the reinforcing bar 13 is embedded in each foundation block 10, the strength and durability of the building foundation are improved. Further, since the foundation blocks 10 are arranged at equal intervals, when a building is constructed on the rising portion 9b, the force applied from the rising portion 9b to the footing 9a is made uniform, so that the strength and the strength are further improved. The durability can be improved. In addition, since the shape and structure of the basic block 10 are simple, the production is easy, mass production is easy, and the production cost is low. This is particularly advantageous when used in large quantities for building houses.

(4) Other Embodiments The present invention is not limited to the above-described embodiments, and the shape, number, size, material, and the like of each member can be appropriately changed. That is, the shape of the basic block 10 does not necessarily have to be the same as in the above embodiment. For example, in the above-described embodiment, the facing surfaces of the two convex portions 12 are inclined to improve the flow of concrete, but may be vertical surfaces. Further, the main body 11 or the protrusion 12 is not limited to a rectangular parallelepiped shape, and may be, for example, a polygonal column shape or a columnar shape. Also, as shown in FIG. 8, if the upper surface 11a of the main body 11 is provided with a curved recess so that the placed reinforcing bar 6a naturally comes to the center of the upper surface 11a, the alignment of the reinforcing bar 6a becomes better. It becomes even easier.

The number of reinforcing bars 6a, 6b, 13 embedded in the footing 9a, the rising portion 9b, and the foundation block 10 can be freely increased or decreased at the design stage. Also, if the material used for the architectural foundation composed of the footing 9a and the rising portion 9b, the foundation block 10 and the foundation 3 is also a concrete material, its component ratio and material can be freely changed at the design stage. It is possible. The component ratios and materials of the building foundation, the foundation block 10, and the foundation 3 can be different or all the same. For example, the basic block 10 can be formed of ceramics or stone.

If the rising formwork 7 can be removed after the concrete has solidified, the rising formwork 7 can be fastened to the upper surface 12a of the projection 12 of the base block 10 with bolts or the like when pouring concrete. Is also good. With this configuration, it is possible to prevent the rising mold 7 from being displaced when the concrete is poured. The space for forming the footing 9a, which extends from the lower part of the rising formwork 7 to the left and right, is open at the upper part. However, when pouring concrete, it is possible to attach a lid to cover the upper part. With this configuration, the lid can prevent the concrete from overflowing from between the base forms 4.

In the above-described embodiment, the straight portion of the fabric foundation has been described. However, the corner portion may use the rising formwork 7 or the reinforcing bar 6 bent along the corner, or a plurality of rising portions. What formed the corner part along the corner by combining the formwork 7 and the rebar 6 may be used. In addition, some members in the above-described embodiment can be omitted, and the labor and cost for manufacturing can be saved. For example, the reinforcing bar 13 embedded in the base block 10 can be omitted. It is also possible to build a foundation without using the base formwork 4.
