繋ぎ梁よりなるコンクリート基礎を構築している。[Prior Art] Conventionally, in concrete foundations for large buildings such as factories, warehouses, or condominiums, underground footings are provided underground at each column location to support the column load pressure, and underground footings are provided at each wall location underground. An underground connecting beam to support the wall load pressure is constructed on-site using reinforced concrete and connected to each other, and a column is erected on the top of the underground footing, and a wall is constructed on top of the underground connecting beam to connect the column. The concrete foundation consisting of underground footings and underground connecting beams supports the entire load of the building, and prevents damage caused by the building's subsidence, tilting, etc., thereby increasing its durability. It is something. When constructing the concrete foundation mentioned above, holes for underground footings and grooves for underground connecting beams are drilled in the ground, and concrete is poured to an appropriate thickness at the bottom of these holes and grooves to form underground footings and underground connecting beams. The reinforcing bars for the connecting beams are arranged and assembled, a formwork is framed on the outside of these reinforcing bars, and concrete is poured inside to construct a concrete foundation consisting of underground footings and underground connecting beams. .

Grooves are excavated that are shallower than the holes for arranging the connecting beams and that communicate with each other. An underground footing is constructed by casting reinforced concrete into a predetermined shape in the hole. Next, an underground connecting beam that has been formed into a predetermined shape with reinforced concrete and has horizontal reinforcing bars protruding from the end face is fitted into the groove, and the vertical reinforcing bars protruding from the upper surface of the underground footing and the underground connecting beam in the longitudinal direction are fitted into the groove. The horizontal reinforcing bars protruding from the end surfaces are arranged to intersect with each other on the top surface of the underground footings, and then concrete for connecting them is poured to connect each underground footing and the underground connecting beam to complete the construction of the concrete foundation. . Therefore, since the underground connecting beams are formed in advance in a factory, etc., various work such as assembling reinforcing bars, formwork, and concrete pouring on site can be simplified to only the underground footing inside the hole, which can be done efficiently with a small number of workers. It will be possible to construct it. Additionally, since the amount of concrete poured is small, the pouring work is not affected by the weather, and there is little loss of concrete flowing out, resulting in significant savings in construction costs.

的な施工ができ、施工経費が大幅に節約される。As explained above, according to the method for forming a concrete foundation for a building according to claim 1, holes for constructing underground footings are formed in the ground where each pillar of the building is located, and A groove for placing an underground connecting beam is excavated in the ground that will be the wall location so that it communicates with the ground, and an underground footing made of reinforced concrete is cast on-site in the hole, and multiple vertical reinforcing bars protrude from the top surface. On the other hand, an underground connecting beam with a plurality of horizontal reinforcing bars protruding from the longitudinal end face is molded with reinforced concrete, and the formed underground connecting beam is fitted into the excavated groove to remove the horizontal reinforcing bars of the underground connecting beam. By intersecting the longitudinal reinforcing bars of the underground footings and the longitudinal reinforcing bars of the underground footings, and then pouring concrete for connecting them on the top surface of the underground footings and connecting the underground connecting beams to each underground footing, it is possible to assemble the reinforcing bars on-site, formwork, Various tasks such as concrete pouring are simplified, and construction can be carried out efficiently with a small number of workers.
Construction costs are significantly reduced. In addition, because the amount of concrete placed on site is small, construction is not delayed due to weather, etc., and there is little loss of concrete flowing out. Next, according to the concrete foundation structure of a building according to claim 2, reinforced concrete is cast on-site in a predetermined shape in a hole drilled in the ground where each column of the building is located, and a plurality of vertical reinforcing bars are installed on the top surface. It comprises a protruding underground footing, and an underground connecting beam that is connected to the hole and is fitted into a groove excavated in the ground that serves as the wall of the building, and that is pre-formed into a predetermined shape with reinforced concrete. , a plurality of horizontal reinforcing bars are provided protruding from the longitudinal end face of the underground connecting beam, and the vertical reinforcing bars of the underground footing and the horizontal reinforcing bars of the underground connecting beam are arranged to intersect with each other on the upper surface of each underground footing, and then By pouring connecting concrete on the top surface of the footings and connecting underground connecting beams to each underground footing, various works such as assembling reinforcing bars, formwork, and concrete pouring on site can be simplified, and can be done by a small number of people. Workers can perform construction efficiently and construction costs can be significantly reduced.
