Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor panel used in building units and the like.

[Prior Art] Recently, unit buildings have become widely used in order to increase the industrial production rate of buildings and reduce the cost required for construction. The unit building is a special public building built in 1982.
As shown in Publication No. 30978, this is a type of building in which a single building is divided into several building units in advance and constructed and assembled at the construction site. A building unit that constitutes each unit of a building is constructed by attaching structural facing materials to each framework such as walls and floors to form wall panels or floor panels, and then erecting wall panels on each side edge of the floor panels. connected in the set state. As a result,
A box-shaped building unit will be completed. The completed building unit is transported to the construction site and installed on a previously prepared foundation.
A plurality of building units are adjacent to each other vertically and horizontally on the foundation, resulting in the construction of a multi-story unit building.

In the case of a unit building using the conventional wall construction method, the building unit is installed on the foundation with each lower side edge of the building unit, that is, each side edge of the floor panel, being placed correspondingly on the foundation. It is done. In addition, when mounting the building units that make up the upper floor to the building units that make up the lower floor, each lower side edge of the building unit that makes up the upper floor, that is, each side edge of the floor panel, makes up the lower floor. This is done in direct correspondence to the top of the wall panel of the building unit. This is the load of the building unit on the foundation, or the load of the building unit on the upper floor against the building unit on the lower floor,
In particular, this is to distribute the load of the wall panels to the building units that make up the foundation or lower floors.

[Problems to be Solved by the Invention] When using the above-mentioned conventional construction method, it is necessary to form the foundation at the construction site in advance so as to be able to support each side edge of the building unit. Furthermore, it is necessary to ensure that the lower side edges of the building units that make up the upper floors correspond to the wall panels that make up the lower floors.
Therefore, the size of the room space formed by the upper and lower building units is constant, and the degree of freedom in the layout of the unit buildings is restricted. Furthermore, the degree of freedom in designing and constructing the foundation is also restricted.

Therefore, a construction method may be considered in which the foundation or wall panels are not placed below the side edges of the floor panels that make up the building unit.

However, if the foundation or wall panel is not placed below the side edge of the floor panel as described above, the load acting on the side edge of the floor panel cannot be transmitted to the foundation or wall panel. As a result, the side edges of the floor panel exhibit an abnormally large amount of deflection, which is not appropriate.

The present invention aims to improve the strength and rigidity of at least one side edge of a floor panel.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a floor panel in which a flooring material is attached to the upper surface of a floor framework,
A floor beam having a height greater than the height of the floor framework is arranged on at least one side edge of the floor framework.

[Function] According to the present invention, since the floor beam having a height greater than the height of the floor framework is provided on at least one side edge of the floor frame, the strength of at least one side edge of the floor panel is increased.
It becomes possible to improve rigidity.
