BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating / sound absorbing material locking method or method, and more particularly to a building material having heat insulating and / or sound absorbing properties such as glass wool or rock wool. TECHNICAL FIELD The present invention relates to a locking tool and a locking method for locking a wall to a wall surface.

[0002]

2. Description of the Related Art As a partition wall for a building or a work, a light-weight steel partition wall of a so-called frame structure in which a building board such as a gypsum board is attached to a stud of a steel stud, or a stud is a self-supporting stud. A partition wall of a so-called non-stud structure of a type omitting is used for practical use. In the partition wall having such a structure, in order to improve the heat insulation performance and / or the sound insulation performance of the partition wall, a molding material of glass wool or rock wool, for example, a mat or a molding plate of glass wool,
Alternatively, a rock wool molding plate or the like is inserted or filled between the board surfaces on both sides facing the space in the wall, for example, between the back surfaces of the facing gypsum boards. In order to fix a building material (hereinafter referred to as a heat insulating / sound absorbing material) having a relatively low hardness surface or a porous surface, such as a glass wool or rock wool molding material, at a predetermined position of a wall, it is generally used. Is a tool such as a tucker or a stapler. For example, the heat insulating / sound absorbing material is fixed to the board surface constituting the wall body by a locking tool such as staples, or is screwed to the board surface.

[0003]

However, since the fasteners such as staples or screws fixed to the board are gradually reduced in fixing ability due to the elastic restoring force of the heat insulating / sound absorbing material, the heat insulating / sound absorbing material is reduced. Is difficult to hold for a long time. In particular, such a locking device is relatively easy to relax with respect to a board made of a relatively weak base material such as gypsum board, and thus it is difficult to secure a perfect fixing state for many years. Therefore, due to incomplete or insufficient locking, the heat insulating / sound absorbing material containing moisture or the like may be displaced downward or droop. Actually, when the board constituting the partition wall is removed after the partition wall is constructed, the locking tool is disengaged or loosened, and the heat insulating / sound absorbing material is displaced downward. Therefore, an improvement measure for preventing downward displacement or drooping of the heat insulating / sound-insulating material is desired. Further, the heat insulating material arranged in the inner space of the outer wall needs to avoid moisture or water. For example, regarding the construction of the heat insulating material, it is necessary to take measures to prevent internal dew condensation. For example, on the outer wall of a house, the heat insulating material is generally arranged so as to be in close contact with the board on the indoor side and form an air layer between the board on the outdoor side and the like. If a gap is created between the indoor board and the heat insulating material due to displacement of the heat insulating material, construction failure, or the like, the problem of internal dew condensation easily occurs. Therefore, there is a demand for a locking device or a locking method capable of reliably disposing the heat insulating material at a desired position in the wall space and holding the position of the heat insulating material to secure a predetermined air layer.
