Description

  The present invention relates to a fixing structure for fixing a deck material to a structural material such as joists.

  Conventionally, when fixing a deck material arranged in parallel on a structural material such as joists, for example, it is very common to screw the deck material to the structural material from the top surface. (Refer to FIG. 8 of Patent Document 1), the screw head is not only exposed on the top surface of the deck material to impair the beauty, but also the screw head protrudes on the top surface and the pedestrian is injured on the foot. There is also a danger, and the fixing structure as shown in FIG. 8B is not necessarily a stable fixing although the screw head is not exposed on the top surface of the deck material.

  Furthermore, as disclosed in Patent Document 1 and Patent Document 2, a locking groove of a fixing bracket is provided on the side surface of an adjacent deck material facing, and the deck material is fixed by a fixing bracket that locks in the locking groove. The fixing structure is effective for solving the above-mentioned problem because the screw head is not exposed on the top surface of the deck material. In the case of a construction method that fixes to the deck etc., it is difficult to arrange the adjacent deck materials through joints of a certain width at the time of construction or partial repair of the deck, or both sides facing the adjacent deck materials It is not always easy to install the fixing bracket between the locking grooves on the surface, and it is difficult to arrange the fixing bracket in an appropriate position. There were difficulties. Moreover, although the screw head is not exposed on the top surface of the deck material, the screw head can be visually recognized from above, so that it is not necessarily excellent in aesthetics.

  In addition, since there are people who dislike the anxiety caused by things falling downward or seeing through the bottom of the deck, the joint between the deck materials should be as narrow as possible. Moreover, it is desired that the width of each joint is constant. However, in order to screw the fixing screw for the deck material through the joint, a width corresponding to the diameter of the screw head of the fixing screw is required for the joint.

  On the other hand, for example, like a deck fixing member 4 disclosed in Patent Document 1 or a connecting metal fitting 3B disclosed in Patent Document 2, it is directly fixed to a joist etc. with a screw, and the fixed portion thereof In the structure in which the pressing portion 45 or the locking piece 35 extending on both sides of the deck member is inserted into the locking groove on the side surface of the deck material and fixed, each deck is connected via a joint having a width close to a certain screw head diameter. It is difficult to arrange the materials, and the shape of the locking groove on the side surface of the deck material for fixing the deck material is complicated, and the front and back surfaces of the deck material cannot be used interchangeably as a walking surface. .
