Description

[Detailed description of the invention] [Industrial application field] The present invention relates to unit buildings.

[Prior Art] A unit building is formed by interconnecting building units arranged vertically or horizontally, and furthermore, each building unit is formed by joining each component. The constituent materials of each building unit are pillars,
There are floor beams, ceiling beams, etc. The pillars are erected at the corners of the building unit; for example, in a rectangular parallelepiped building unit, the pillars can be erected at each of the four corners. The floor girder is a component of the peripheral part of the floor surface of a building unit, and each end is joined to the lower end side of an erected support. The floor girder is capable of supporting each end of the small beams and joists, which are the structural members in the direction of the floor surface. The ceiling girder is a component of the peripheral part of the ceiling surface of the building unit, and each end is joined to the upper end side of the erected support column. The ceiling beam can support each end of the ceiling beam, which is a component of the ceiling section.

By the way, when each building unit formed in this manner is installed at a construction site, it is installed on a foundation that is planted in the ground at the site. FIG. 9 is a structural diagram showing how a conventional building unit is installed on a foundation.

The foundations 11 on the ground 10 can support each end of the building units 12 constituting the lower floor. Therefore, each foundation 11 is placed on the ground at a constant interval L1 corresponding to the length of the building units 12. 10. The building unit 12 is installed on the foundation 11 by supporting the pillar 13, which is a component of the building unit 12, on the foundation 11. The floor beam 14 connected to each lower end side of the pair of pillars 13 is supported by placing the center portion of the floor beam 14 in the longitudinal direction on a bundle 15 planted in the ground 10. As a result, when a load and an impact of W1 are applied to the floor surface above the floor girder 14, these can be supported by the bundle 15.

[Problems to be Solved by the Invention] However, since the bundle 15 and the floor girder 14 were not connected, when the bundle 15 sinks downward in the direction of the arrow, the gap between the bundle 15 and the floor girder 14 A gap T1 will be formed between the two. If an excessive load W1 or impact is applied to the floor surface of the building unit 12 in this state, the floor girder 14 may bend as shown by the two-dot chain line or may vibrate in the direction of arrow A. Such floor vibrations are considered to cause floor rumble or vibration noise transmitted to other building units, thereby deteriorating the walking or living feeling of the unit building.

Conventionally, according to the floor construction method described in JP-A-54-164309, support legs that enable height adjustment are arranged between the flooring material and the ground, and the height of the support legs is Although the adjustment prevents the flooring material from bending and vibrating due to ground subsidence, adjusting the height of the support legs is considered to be complicated.

The present invention aims to improve the strength of the floor portion of a building unit and to reliably and easily prevent floor vibrations of the building unit.

[Means for Solving the Problems] In order to achieve the above object, the present invention arranges opposing floor girders of a plurality of substantially rectangular parallelepiped building units on a line foundation planted in the ground, and
A unit building formed by installing the remaining opposing floor girders of the building unit on a bundle planted in the ground, with a buffer between the bundle and the remaining opposing floor girders. They are connected by a connector via a certain spacer.

[Function] According to the present invention, since the floor beam and the bundle are connected by the connector through the cushioning spacer, it is possible to improve the rigidity of the floor beam in the building unit. In addition to improving the strength of the parts, it becomes possible to reliably and easily prevent floor vibrations of the building unit.
