BACKGROUND OF THE INVENTION
The present invention relates to a floor panel and a building unit using the floor panel.
[0002]
[Prior art]
The building unit method, which is a method for industrial production of houses, is to assemble a three-dimensional building unit of a predetermined size that can be transported at a factory and join the multiple units at the construction site to complete the building. This building unit is usually constructed by assembling a floor panel, a wall panel, and, if necessary, a ceiling panel.
[0003]
Conventionally, for example, as shown in FIG. 3, the floor panel 10 used in a building unit is a joist in a state where it is perpendicular to the joists 11, 11,. 13 and 13 are joined by a nail 27 to form a rectangular frame, and receiving members 14, 14... Bridged between the joists 11, 11,. The face material 15 is attached to the upper surface of the floor frame.
[0004]
Further, on the back side of the floor panel 10, a joint frame 22 is attached to the lower side of the end joist 13 along the length direction of the end joist 13, and one side edge portion 23 of the end joist 13 is longer than the end joist 13. Is also projected to the inside of the floor panel 10. Usually, the joint lower frame 22 is provided with a plurality of bolt insertion holes (not shown) at predetermined intervals along the length direction thereof. A connection bolt that connects the building units of the floor and the lower floor is inserted, and a solid frame structure is configured by fastening the anchor bolt or the connection bolt.
[0005]
[Problems to be solved by the invention]
When a space such as a stairwell is required for the floor panel, for example, as shown in the floor panel 101 shown in FIG. Opening A is provided.
However, since the opening A is provided and the joist 11 is reduced, the floor panel becomes weak against bending and twisting from the outside, and the lateral width of the end joist 131 can be increased for this reinforcement. Although necessary, due to the increased width of the end joist 131, the side end portion 23 of the joint frame 22 that protrudes from the conventional end joist 13 to the inside of the floor panel 10 is hidden under the end joist 131. There arises a problem that the load applied to the joists 12 and 12 cannot be supported by the joint lower frame 22.
[0006]
In order to solve this problem, there is a method using a beam bracket or the like. However, this method increases the number of extra parts and their mounting work, impedes productivity, and increases the cost.
[0007]
Further, as shown in FIG. 5 (only one corner B in FIG. 4 is shown), the end joist 131 is shortened, the end portion of the side joist 12 is placed on the joint lower frame 22, and the end joist 131 from the side surface of the side joist 12. Although a method of joining to the end of a wood with a nail 27 is also conceivable, this method must change the direction of nailing by 90 °, cannot use a conventional floor panel manufacturing apparatus, and requires a change in work space. This causes new problems.
[0008]
