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 each building unit is formed by joining each component. The constituent materials of each building unit include columns, 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 the building unit, and is formed by joining each end to the lower end side of an erected support. The floor beams are capable of supporting each end of the small beams and joists, which are the structural members below 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 the building units formed in this way are connected vertically, the constituent members of each unit are joined in the state shown in FIG. 6. FIG. 6 is a structural diagram showing how the building units constituting the upper and lower floors of the conventional system are connected.

A ceiling girder 11 is arranged between the upper ends of the pair of columns 1O of the lower floor building unit. Each end of the ceiling beam 11 is joined to the upper end side of the column 10 with a connecting piece 12 interposed therebetween, and the connecting piece 12 has a larger height than the ceiling beam 11. Ru. Therefore, a gap T1 is formed between the upper end of the pillar lO and the upper part of the ceiling beam 11.

On the other hand, a floor girder 14 is provided between the lower ends of the pair of pillars 13 of the upper floor building unit. Each end of the floor girder 14 is
A connecting piece 15 is connected to the lower end side of the support column 13 with the connecting piece 15 interposed therebetween, and the connecting piece 15 has a larger height dimension than the floor girder 14. For this reason, the pillar 13
A gap T2 is formed between the lower end of the floor girder 14 and the upper part of the floor girder 14.

The upper floor building unit and the lower floor building unit are connected by joining the upper ends of the corresponding columns 10 of the lower end building unit and the upper ends of the corresponding columns 13 of the upper floor building unit. Therefore, in conventional twin-unit buildings, a gap T3, which is the sum of the gap Tl and the gap T2, was formed between the floor beam 14 on the upper floor and the ceiling beam 11 on the lower end.

[Problems to be Solved by the Invention] When the gap T3 is formed between the upper floor and the lower floor as described above, for example, when a load and impact of Wl are applied to the floor surface of the upper floor building unit. , 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 cause floor rumble or vibration noise that is transmitted to lower floors and adjacent upper floor building units, reducing the feeling of walking or living in a unit building.

In the building described in Japanese Utility Model Application Publication No. 5IA-102713, the ends of the floor beam on the upper floor and the ceiling beam on the lower floor are conventionally connected to each other. However, even with such a method, the existence of the gap T3 could not be eliminated, and floor vibration was considered to occur.

The present invention aims to improve the strength and rigidity of the entire unit building, and to prevent floor vibrations on the upper floors of the unit building.

Means for Solving Problem E] In order to achieve the above object, the present invention provides a unit building in which building units arranged above and below are connected to each other. A spacer is interposed in the gap formed between the floor beam of the upper floor building unit and the ceiling beam of the lower floor building unit, and the spacer is connected to the floor beam of the upper floor building unit and the ceiling beam of the lower floor building unit. They are integrally connected using a connector.

[Operation] According to the present invention, the floor beam of the upper floor building unit and the ceiling beam of the lower floor building unit are integrally connected by the connector with a spacer interposed therebetween. This results in
It becomes possible to improve the coupling performance between the upper and lower building units, improve the strength and rigidity of the unit building as a whole, and prevent floor vibrations on the upper floors of the unit building.
