[Problems to be Solved by the Invention] However, in the conventional example described above, it is necessary to pour concrete twice, at the footing foundation and at the rising foundation, and furthermore, the concrete must be poured twice at the footing foundation and at the rising foundation. It is necessary to perform the framework, curing the concrete after pouring, removing the formwork, etc., resulting in a problem that the number of man-hours increases, the construction is time-consuming, and the construction period is long.

The present invention is intended to solve the above problems, and its purpose is to provide a cloth foundation structure that can reduce the number of man-hours and significantly shorten the construction period.

[Measures Pi for solving problem i11] In order to achieve the above object, the structure of the cloth foundation in the present invention includes a rising part raised from the footing foundation part 1 of the cloth foundation A formed of concrete. 2 is formed by a rising base portion 3 having a lattice structure.

[Operation] The base tIA is formed by providing a rising base part 3 having a lattice structure on a rising part 2 raised from the footing base part 1. By forming the rising part 2 with the rising foundation part 3 of the lattice structure in this way, it is not necessary to form the rising part 2 by pouring concrete, and it can be formed by a dry construction method, and it is possible to form the rising part 2 by using a dry method. The labor required for curing, formwork, and removal can be omitted, and the number of man-hours can be significantly reduced.

Embodiment 1 FIG. 1 is a sectional view of an embodiment of the present invention. The footing foundation part 1 constituting the cloth foundation A is formed by pouring and curing concrete in a formwork in which reinforcing bars 4 are arranged. Standing base VR with metal lattice structure! Part 3
It is installed protrudingly.

The rising 9 base part 3 of this lattice structure consists of an upper chord member 3a and a lower chord member 3, such as channel steel, which are arranged to face each other.
It is constructed of a lattice structural member 3' shaped like JR by arranging diagonal members 3c such as reinforcing bars in a zigzag pattern in the opening between b and b.
The lower part of this lattice structural member 3' is connected to the footing base part 1.
A rising base part 3 having a lattice structure is provided to protrude upward from the footing base part 1 so as to be buried within the footing base part 1. An external finishing material 5 is provided on the side surface of this lattice structural member 3'.
Panel mounting plates 6 are mounted across the gap between the upper chord member 3a and the lower chord member 3b at a constant pitch along the direction of the hand force so that the panel 5a can be easily attached later. h provided on plate 6
Reference numeral 68 designates a ventilation opening so that the panel 5a can be attached using a screwdriver 7 through the screw hole 6a.

Moreover, on the upper surface of the upper chord material 3a, there is a base II! I! Attachment holes 9 for attaching anchor bolts for attaching the base to A are provided at a constant pitch. If the mounting holes 9 for installing anchor bolts are provided in the upper surface of the upper chord member 3a that is manufactured in advance in a factory in this way, the positioning accuracy of the anchor bolts will be improved, and it will be possible to improve the positioning accuracy of the anchor bolts. There is no need to reposition the anchor bolt. In addition, if the rising foundation part 3 is formed of the lattice structure member 3' formed by providing the diagonal members 3c in a zigzag shape between the upper chord member 3a and the lower chord member 3b, the rising foundation part 3 will be ventilated. When providing the opening 8, as shown in FIG.
The ventilation opening 8 can be provided at any position of the opening without providing a reinforcing member. In other words, conventionally, when providing the replacement hexagon 8 in the rising portion 2, no reinforcing member is provided in the diagonal direction, so as shown in FIG. However, in the lattice structure member 3', reinforcement is unnecessary because the diagonal members 3c are provided, and ventilation holes 8 can be installed at any position on the exterior finishing material 5.
It is possible to set the position of

Moreover, at this time, if the rising base part 3 is formed of the lattice structure member 3', only the ventilation opening 8 is provided in the panel 5a as the external finishing material 5, and the rising base part 3
It is possible to form a ventilation hole 8 that communicates between the inner surface and the outer surface.

Therefore, during construction, the split stone or crushed stone 10 provided at the installation position of the cloth foundation A is compacted, and then concrete 11 is poured partially or continuously, and the footing of the cloth foundation A is placed here. We marked out the markings for the installation of the foundation part 1, and installed a height adjustment jig that can adjust the height in the vertical direction to level the top of the cloth foundation A (the top of the rising foundation part 3) on the waste concrete 11. Install the tool 12. Next, on this height adjustment jig 12, the column walls 13 connected to both ends of the lattice structure member 3' in the direction of the force direction at a 4:7 joint are sequentially placed, and as shown in FIG. As shown in Fig. 1, concrete is poured and the lower part of the lattice structural member 3'' is buried in the footing foundation 1 to form the footing foundation 1. At this time, the formwork 14 for pouring concrete is placed. may be attached to the lattice structural member 3' in advance, and if the formwork 14 is previously installed on the lattice structural member 3' in this way, the concrete can be placed immediately after the lattice structural member 3' is installed. In this way, the cloth curtain t!A with the lower part of the lattice structural member 3' buried in the footing foundation 1 is constructed as shown in FIG. There is also a lattice M located on the outer periphery.
The structural member 3' is provided with an external finishing material 5 as shown in FIGS. 5 and 6.
