Abstract

PURPOSE:To reduce manhours required for execution at a construction site and to improve the accuracy and quality of the execution. CONSTITUTION:The whole of a bundle foundation A is made of precast concrete. Its periphery is provided with a frame 10, and its center is provided with an anchor bolt holding part 11. A connecting part 12 is provided between the frame 10 and the anchor bolt holding part 11. A concrete filling space 13 is formed in a part enclosed by the frame 10. The bundle foundation A formed in this way is set at a construction site, and concrete is filled up into the concrete filling space 13 for executing a foundation.

Description

[Detailed description of the invention]

0001

FIELD OF THE INVENTION This invention relates to the construction of large bundle foundations used to support large bundles of floors.

0002

2. Description of the Related Art Conventionally, this type of large bundle foundation was formed as shown in FIG. A rectangular concrete formwork 3 is assembled on the concrete surface 2 provided on the chestnut stone 1, reinforcing bars 7 are placed on the concrete surface 2 within the concrete formwork 3 via spacer blocks 4, and the concrete formwork 3 is assembled. Anchor bolt support plate 5 is constructed and installed on top of the anchor bolt support plate 5, and anchor bolt 6 is attached to anchor bolt support plate 5.
support. In this state, concrete is poured into the area surrounded by the concrete formwork 3 to form a bundle foundation, and after the concrete hardens, the concrete formwork 3 is removed.

0003

[Problems to be Solved by the Invention] However, in such a conventional example, there is a problem that the concrete formwork 3 etc. must be assembled and constructed on site, requiring a large number of man-hours for construction, and also has the problem of accuracy. There is a problem that the quality is not constant. The present invention has been made in view of the above problems, and an object of the present invention is to provide a bundled foundation that can reduce the number of on-site construction steps and improve accuracy and quality.

0004

[Means for Solving the Problems] In order to achieve the above object, the bundle foundation A of the present invention is entirely made of precast concrete, and includes a frame 10 on the outer periphery, an anchor bolt holding part 11 in the center, and a frame 12. and the anchor bolt holding part 11, and a concrete filling space 13 provided vertically penetrating the part surrounded by the frame 10.
It is characterized by having the following.

[0005]

[Operation] According to the above structure, construction can be carried out by simply placing the bundle foundation A made of precast concrete on the concrete surface 2 on the chestnut stone 1 and filling the concrete filling space 13 of the bundle foundation A with concrete. This reduces on-site construction man-hours and improves accuracy and quality.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The bundle foundation A is made of precast concrete and is formed as shown in FIG. A rectangular frame 10 is provided on the outer periphery of the bundle foundation A, an anchor bolt holding part 11 is provided approximately in the center of the frame 10, and a connecting part 12 is provided between the frame 10 and the anchor bolt holding part 11. is provided. The inside of the frame 10 is a concrete-filled space 13 that penetrates vertically except for the portion where the anchor bolt holding part 11 and the connecting part 12 are located. The anchor bolt 6 is attached to the anchor bolt holding portion 11 so as to pass through the anchor bolt 6.

[0007] The bundle foundation A constructed as described above is manufactured in a factory and constructed on site as follows. The bundle foundation A is placed on the concrete surface 2 of the chestnut stone 1, concrete is filled into the concrete filling space 13 of the bundle foundation A, and the concrete is hardened. As a result, the bundle foundation A with good accuracy and quality can be constructed by simply filling it with concrete on site. In other words, by using the bundle foundation A made of precast concrete, the accuracy of the pitch of the anchor bolts 6 and the horizontality of the top of the anchor bolts 6 is improved, and the quality is improved by being formed to standard dimensions and reducing damage to the appearance. can.

[0008]

[Effects of the Invention] As described above, the bundle foundation of the present invention is made of precast concrete, so it can be constructed by simply setting it at a predetermined location on site and filling the concrete filling void with concrete. This method simplifies on-site work and reduces the number of construction man-hours, and since it is pre-manufactured in a factory, accuracy and quality are improved.Furthermore, when manufactured in a factory, concrete-filling voids are free of space. Even if it is large, it is lightweight and easy to handle.
