JP3000013U - Precast concrete assembly foundation for stilt buildings - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] The purpose is to provide an underfloor part of a one-story high-rise building by joining and assembling precast concrete products. [Structure] An assembly foundation for a high-floor building in which a precast concrete plate making and a hollow cylindrical column 1 are connected integrally by a PC steel rod 6.

Description

[Detailed description of the device]         [0001]     [Industrial applications]   This invention relates to the foundation of stilt buildings.         [0002]     [Prior art]   If the structure of the underfloor of a conventional high-floor building is a wooden structure, a bundle is built on a bundle stone, and a horizontal material, diagonal Reinforce with concrete and fix the floor material on top of it, or in-situ reinforced concrete on an independent foundation It is common to use a ramen structure.         [0003]     [Problems to be solved by the device]   A structure suitable for the climate of Japan as shown by the existence of many remains that endure wind and snow for hundreds of years. Despite this, stilt buildings are currently used in special buildings such as shrines and temples, and in rough terrain. There is a limited state such as villa construction that makes the structure under the floor solid with wood In some cases, a large amount of good quality material is required. In case of concrete A process is required.         [0004]   The present invention makes such shortcomings of the conventional technology small and makes the precast concrete The joining of the members provides an advantageous foundation and underfloor structure.         [0005]     [Means for Solving the Problems]   In this invention, PC version, lower version (2), upper version ( 3) Bring in the PC-made cylindrical column (1) to the topographical construction site and place the lower plate (2) in place. And fix one end of the PC steel rod (6) to the lower plate (2) and stand it. The hollow cylindrical column (1) Put the PC steel rod (6) through the part. Establish the specified steel rod and pillar, and put them through the holes in the upper plate (3). The upper plate (3) is installed so that the end of the PC steel rod (6) goes out from the upper surface. PC steel rod (6 ) Is tightened and fixed by the fixing plate (4) and nut (5).         [0006]   Fix the base of the upper building to the flat upper surface of the upper plate (3) by means such as Porto. . The space below the ground surface is backfilled. Or use the earth stop and other means to use the space .         [0007]     [Work]   Tension the PC steel rod (6) appropriately to lower plate (2), upper plate (3) and cylindrical column (1). Lower plate (2), upper plate (3) ), If the cylindrical pillar (1) is integrated, the load of the upper building will be more stable on the ground than the lower plate (2). It is transmitted as well as the underlying building.         [0008]     【 Example】   FIG. 1 is a basic embodiment of the present invention, (a) plan view, (b) elevation view, (c) FIG. 1 upper plate, 1 lower plate, 4 columns, PC steel rod, fixing plate, It consists of four pairs of shoes.         [0009]   2 (a) and 2 (b) show an implementation for a larger area by combining the basic embodiments. Here is an example. It is a (a) top view and a (b) elevation view. (C) and (d) are Narrow width of the lower plate (2) and the upper plate (3) for easy loading and installation on site It is a (c) top view and an (d) elevation view in an example at the time of dividing into a plate. In either case Also in the case of plate connection, use a commonly used method such as binding with a PC steel rod. Yes.         [0010]   Fig. 3 shows an example of using the lower space, where earth backstops are installed without backfilling. It is a sectional view at the time of installing a basement in a guard space.         [0011]       [Effect of device]   In the present invention, it is a factory product that is more advantageous than cast-in-place concrete in accuracy and delivery time. Bringing a precast concrete to a construction site and joining it by simple work It provides the underfloor portion of a solid stilt building.         [0012]   Due to the structure with a large contact area, it is possible to cope with soft ground.         [0013]   There is less necessity to make the shape of the foundation the same depending on the shape of the upper building, and more freedom Is high. The floor of the superstructure can be omitted. Use that space for the basement and other It
