Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fixing tool for boards used when attaching boards such as a heat insulating panel or a plaster flat board or a fiber board to a mounting base such as a wall or a ceiling. More specifically, a female member and a male member that are engageable with each other are provided, a locking recess is formed in the female member, and the male member is elastically engaged with the locking recess of the female member. By forming a locking protrusion that prevents the male member from slipping out of the female member, one of the members has a mounting portion for the mounting base, and the other has a mounting portion for the mounting base. The present invention relates to a board fixture that has a holding portion capable of pressing and fixing boards.

[Conventional technology]

Conventionally, this type of board fixture has the mounting portion formed on the male member and the pressing portion formed on the female member so that the mounting portion projects to the side portion of the male member. There is one in which a plurality of screw holes are formed in the mounting portion so that a plurality of screws for mounting the mounting portion on the mounting base can be individually inserted (for example, see Japanese Utility Model Publication No. 57-15946). It was

[Problems to be solved by the invention]

In the case of this conventional fixture for boats, when the male member is mounted on the mounting base, at the construction site, the male member is pressed against the mounting base with one hand, or temporarily fixed with an adhesive. In this state, the screw must be inserted into the screw hole of the mounting portion of the male member, and the screw must be screwed in with care so that the screw does not fall off, so that there is a problem that it takes a lot of time and labor to mount the boards.

Further, since the mounting portion is arranged so as to project to the side portion of the male member so that the screw can be easily inserted into the screw hole, the projecting mounting portion becomes bulky and the handleability of the male member becomes poor. There was also a problem.

An object of the present invention is to provide a fixture for boards that is easy to handle without being bulky and can be easily installed at a construction site.

[Means for solving problems]

The fixing structure for boards according to the present invention is characterized in that a female member of the female member and the male member, which are provided so as to be engaged with each other, has a mounting portion for a mounting base and a locking recess of the female member. A pressing portion is formed on the male member, which is formed with a locking protrusion that prevents the male member from slipping out of the female member by elastically engaging it, and is capable of pressing and fixing boards or the like with the mounting base. Then, the mounting portion is arranged at a position facing the outside through the locking projection engagement portion of the locking recess, and a screw for mounting the mounting portion on the mounting base is attached to the mounting portion so as to be rotatable only. There is a place.

[Action]

According to the characteristic configuration of the board fixing device according to the present invention, the female part is previously provided with a screw for mounting the mounting part on the mounting base so as to be rotatable only.
At the construction site, it is not necessary to bother to attach a screw to the attachment part or take care not to drop the screw, and the female member can be attached to the attachment base by a simple operation of simply screwing the screw. . Therefore, as in the past, with the male member being pressed against the mounting base with one hand (or temporarily fixed with an adhesive), a screw is inserted into the screw hole of the mounting portion of the male member, and the screw is Compared to screwing in carefully so that it does not fall off, it is possible to perform the mounting work more efficiently.

Further, the female member is formed with a mounting portion for the mounting base, and the male member is formed with a holding portion, and the mounting portion is arranged at a position facing from the outside through the locking projection engaging portion of the locking recess. Therefore, for example, the screw attached to the mounting portion can be tightened by passing a screwdriver through the locking projection engaging portion, and the space in the locking recess can be effectively used as a screw tightening space. As a result, it becomes possible to easily carry out the mounting work without providing an extra projecting portion for mounting the screw on the female member, and the mounting portion is bulky and the handleability of the member is impaired. It becomes possible to prevent that.

[Effect of device]

As a result, it becomes possible to perform the mounting work of the female member at the construction site efficiently and easily with a small amount of labor, and it is possible to realize both the process shortening and the cost reduction of the board fixing work as a whole. It was
