Description

  TECHNICAL FIELD The present invention relates to a double floor structure mainly applied to a detached house and a collective house, and a floor panel used therefor.

  As a first floor of a detached house, a double floor is known in which a plurality of floor panels are supported at a predetermined height by a plurality of support legs installed on soil concrete, and such a double floor is adopted. By doing so, it is possible to abolish Oki and jota.

  When constructing this type of double floor, install a plurality of support legs on the soil concrete, and attach a plurality of strips in parallel so as to straddle between the upper surfaces of the support legs. A plurality of floor panels are arranged so as to straddle.

  However, in the construction as described above, the support legs, the strips, and the floor panels are attached while being positioned in sequence, so that troublesome work is required and a lot of time is required.

  Therefore, a construction method has been proposed in which the floor panel and the strip are attached at the same time by using a floor panel in which the strip is integrally attached in advance, thereby simplifying the construction (for example, patents). Reference 1).

JP-A-6-346577

  FIG. 11 shows a construction state of a general double floor, which is connected to the joint portions 42... Connected via the strips 41... Between the ends of the adjacent floor panels 40. The joint portions 43 are not formed, and the joint portion 43 has a problem that it is weak in strength and easily forms a step. For this reason, in many cases, a joint plate member is separately prepared for the joint portion 43 and the joint portion 43 is coupled via the plate member.

  The same applies to the case of using a floor panel in which the strips are integrally attached as described above. For example, as disclosed in Patent Document 1, the ends of adjacent floor panels that are not connected by the strips are connected to each other. , And connected by a post-installed plate material.

  However, in this case, after the floor panel is attached, a connection work using a plate material is further required, resulting in deterioration of workability.

  Therefore, the present invention aims to provide a double floor structure that solves the above-mentioned problems, is easy to construct, and can firmly and stably connect adjacent floor panels and a floor panel used in the double floor structure. And

  In order to solve the above problems, the double floor structure of the present invention is formed by arranging a plurality of floor panels 1... In a state where they are supported at a predetermined height by a plurality of support legs 2. The floor panel 1 extends in a direction orthogonal to the one end portion 10 while being fixed along the substantially rectangular or substantially square floor base material 5 and the one end portion 10 of the floor base material 5. A band plate 6 and a connecting plate 7 projecting in a direction orthogonal to the other end portion 11 while being fixed along the other end portion 11 orthogonal to the one end portion 10 of the floor base material 5. The band plate 6 is installed on the support leg 2, and the end portion of the floor base material 5 of the adjacent floor panel 1 is installed on the overhanging portion 15 of the band plate 6, The end of the floor base material 5 of another adjacent floor panel 1 is installed on the overhanging portion 17 of the connecting plate 7. The features.

  Further, the strip 6 is extended so as to extend in a direction orthogonal to the other end portion 11 of the floor base material 5, and the extension portion 16 is provided with the other adjacent floor panel 1. The end of the floor base material 5 is installed.

  The floor panel 1 according to the present invention is arranged side by side in a state of being supported at a predetermined height by a plurality of support legs 2. The base material 5, the strip 6 that is fixed along the one end portion 10 of the floor base material 5, and projects in a direction perpendicular to the one end portion 10, and the one end portion 10 of the floor base material 5 A connecting plate 7 projecting in a direction perpendicular to the other end portion 11 in a state of being fixed along the other end portion 11 orthogonal to the other end portion 11 is integrally assembled, and the band plate 6 is attached to the support leg 2. In addition to installing on the overhanging portion 15 of the strip 6, the end of the floor base material 5 of the adjacent floor panel 1 is installed, and another adjacent floor is mounted on the overhanging portion 17 of the connecting plate 7. An end of the floor base material 5 of the panel 1 is installed.

  Further, the support leg 2 is assembled integrally with the back surface of the strip 6, or the heat insulating material 8 is assembled integrally with the back surface of the floor base material 5.

  According to this invention, since the floor panel formed by integrally assembling the floor base material, the band plate, and the connecting plate is used, the band plate and the connecting plate can be attached at the same time only by laying these floor panels. This makes it possible to connect the floor panels stably without causing a step in the joint between adjacent floor panels while simplifying the construction.

  In addition, by installing the end of the floor base material of another adjacent floor panel in the extended portion formed by extending the strip, the position of the support leg is somewhat shifted along the longitudinal direction of the strip. Even then, another adjacent floor panel can be laid stably.

  Furthermore, by assembling the support leg and the heat insulating material integrally with the floor panel, the floor panel can be laid, and at the same time, the support leg and the heat insulating material can be attached at the same time, thereby further improving the workability.
