Description

[Detailed description of the invention] This invention relates to a basement formed by integrating multiple precast concrete wall panels into a box shape by post-tensioning. The purpose is to provide a basement that can be used.

An embodiment of this invention is shown in FIGS. 1 and 2. That is, this basement is a basement in which a plurality of precast concrete wall panels 1... are assembled into a box shape using a post-tension method, and the precast concrete wall panels 1...
As a set of precast concrete wall panels whose wall surfaces face each other, the precast concrete wall panels have anchor bolts 2 embedded so as to protrude toward the inward wall surface at the upper end during forming. 1', 1', and a steel beam 3 is horizontally suspended between the wall surfaces constituted by the pair of precast concrete wall panels 1', 1' via the anchor bolts 2... be.

This embodiment shows a basement with an open-air space 4 attached to the outer wall of the basement to be used as a dry area, sunroom, sun garden, etc., and the steel beam 3 is connected to the open-air space 4 and the indoor space 5.
This steel beam 3 is provided at the boundary of the
A part of Shed 6 is supported.

End plates 3 are provided at both ends of the steel beam 3.
a, 3a are formed, and this end plate 3a,
The anchor bolt 2 is inserted into the bolt insertion hole 3a...
It is connected to the wall by inserting it through and tightening the nut.

The floor structure of this basement is made up of a layer of crushed granite 7 and a layer of concrete 8 on the floor foundation.
A solidifying fluid material is poured to form the floor sublayer 9, and a precast concrete floor panel 10 having ribs 10a... formed on the underside is placed on the floor sublayer 9 before hardening.
The gap between the concave portion of the lower surface of the rib-formed precast concrete floor panel 10 and the upper surface of the lower floor layer 9 is used as a drainage hole 11, and this drainage hole 11 is installed on the floor surface of the open-air space 4 to form a water collection pit 1.
The drainage hole 1 is opened to the bottom of the basement floor to provide a drainage structure.
The drainage hole 11 is connected to the ground surface by a ventilation pipe 13, and the drainage hole 11 is used as a ventilation hole to ventilate the basement.
The non-water collecting pit side end of a is cut out so that each drainage horizontal hole 11... communicates with each other at this cutout.

In FIG. 1, 14 is a skylight provided at the upper opening of the open-air space 4, 15 is a sliding door, and 16 is a floor panel that partitions the basement and the shed 6.

In this embodiment, the precast concrete wall panel 1' corresponding to the boundary between the open air space 4 and the indoor space 5 is a panel with anchor bolts.
The installation position of the panel with anchor bolts can be arbitrarily selected according to the partition design, and even when using the steel beam 3 for supporting the shed, the position of the panel with anchor bolts can be selected according to the layout of the shed. By selecting the arrangement, the steel beam 3 can be placed horizontally at any position.

With this configuration, the anchor bolts 2 can be placed at any position on the standard precast concrete wall panel 1, without using the precast concrete wall panel formed according to the position of the partition or the arrangement of the walls of the shed. By protruding, the steel beam 3 can be easily horizontally installed at any position, the basement partition and the support position of the shed can be freely set, and the whole structure can be made lighter while being highly versatile. .

As described above, the basement of this invention is a basement in which a plurality of precast concrete wall panels are integrated into a box shape by post-tensioning. Anchor bolts were installed protrudingly, and the steel beams were horizontally suspended between the pair of precast concrete wall panels via the anchor bolts, so the steel beams could be easily horizontally suspended at the shed support position and the partition position. , the layout of the shed and the partitions of the basement can be freely set, and the weight can be reduced.
