Description

[Detailed description of the invention] The present invention consists of a mounting member and a fastening member that can hold the board in two stages: a temporary holding state and a complete holding state, and the board is attached to the ceiling base or wall base. The present invention relates to a board mounting tool that streamlines board mounting work and allows for easy correction of construction defects prior to complete board mounting.

As a board mount that can hold a board, such as a ceiling board, by elastic fitting between a locking protrusion and a locking groove, there is a locking protrusion disclosed in, for example, Japanese Utility Model Application No. 53-73717. It is known that a ceiling board is held between clamping pieces that are integrated with the locking protrusions and the locking grooves by elastically fitting the strips and the locking grooves. However, in this type of board mount,
Once the locking protrusion and the locking groove are engaged, it is impossible to release the engaged state, so if a construction defect occurs, for example, the locking protrusion and the locking groove may be installed continuously in a straight line. In cases where the boards to be used are in an irregular state, such as in a zigzag shape, it is difficult to modify the board, resulting in poor flexibility in construction.

The object of the present invention is to provide a board mounting fixture which can solve these problems, and one embodiment of the same will be described below with reference to the drawings.

In the figure, a board mount 1 of the present invention is used to mount a board 2 made mainly of glass wool, for example, and is composed of a mounting member 3 and a fastening member 4. Note that both members 3 and 4 are formed using synthetic resin.

The mounting member 3 is formed by protruding a pair of locking pieces 9, 9 forming a locking groove 7 from the longitudinal center portion of a long mounting board 6 that is attached to the base portion 5 of the ceiling. Edges 10 that bite into the board 2 are protruded from both longitudinal edges of the board.

The fastening member 4 is located at the longitudinal center of the presser plate 11.
Approximately the upper half (outer part) is provided with a protruding engaging protrusion 12 that elastically fits into the locking groove 7, and both side parts 6a, 11a, 6 of the mounting board 6 and the holding plate 11
a, 11a can sandwich opposing end portions 2a, 2a of adjacent boards 2, 2. The both side portions 11a, 11a of the holding plate 11 are gently inclined diagonally upward so that the both side portions 11a, 11a of the holding plate 11 come into close contact with the lower surface of the board 2 due to their spring action during the clamping.

On both sides of the outer part of the engagement protrusion 12, there are saw-blade-shaped small locking protrusions 15 having locking surfaces 13 in multiple stages (four stages in this embodiment) on the inner end side of the engagement protrusion 12.
15, 15, 15... are provided, and a saw-blade-shaped large locking surface 17 having a wider width than the locking surface 13 is provided via the innermost small locking protrusion 15a and the separating part 16. Stop ridges 19, 19 are provided facing each other. Note that the width L1 of the separating portion 16 is the same as that of the small locking protrusion 15.
The height is set slightly larger than the height L2. On the other hand, the entrance portion of the locking groove 7 is formed into a split groove portion 20 in which the separating portion 16 can be accommodated, and the locking groove 7 includes the split groove portion 20.
0, a large locking groove 21 that fits with the large locking protrusion 19 is provided, and a small locking groove 21 that fits with the small locking protrusion 15 is provided following the large locking groove 21. Stop groove 2
2 is provided. In addition, the opposing surfaces of the distal ends of both the locking pieces 9, 9 are connected to the large locking protrusions 19, 19.
Inclined portions 23, 23 are provided which come into contact with the inclined surfaces of.

The dimensions of the small locking protrusion 15 and the large locking protrusion 19 are set as follows. That is, the small locking protrusion 15
Regarding, the small locking protrusion 15 and the small locking groove 22
and are set to engage with each other with an engagement force sufficient to temporarily hold the board 2. The engagement force means that the small locking protrusion 15 can be tightened by twisting the fastening member 4 as necessary.
This refers to the engagement force that is sufficient to release the engagement between the small locking groove 22 and the small locking groove 22. Further, the large locking protrusion 19 is set to such an extent that the board 2 can be completely held firmly and stably by the engagement between the large locking protrusion 19 and the large locking groove 21.

Below, board 2 is installed using board mount 1 of the present invention.
The procedure for attaching this to the ceiling base 5 will be explained based on FIGS. 2 to 5. First, considering the width of board 2,
The mounting members 3 are arranged side by side on the ceiling base part 5 by nailing the mounting boards 6 thereof. After that, both side portions 6a, 11a, 6 of the mounting board 6 and the holding plate 11 are
The end portions 2a, 2a of the board 2 are inserted into the ends a, 11a, and the large locking protrusions 19, 19 are connected to the locking pieces 9, 11a.
The engaging protrusion 12 is inserted into the locking groove 7 until it comes into contact with the opposing surfaces of the inclined parts 23, 23 of 9. In this state, the innermost small locking protrusion 15a is connected to the large locking groove 2.
1 and the other small locking protrusions 15, 15, 15 fit into the small locking grooves 22, 22, 22, respectively, and the boards 2... are temporarily held. In addition, in this embodiment, as described above, the groove width of the split groove portion 20 is smaller than the maximum width of the opposing small locking protrusions 15, 15, and the groove depth is smaller than the height of the small locking protrusions 15. Because it is set to a large size, the innermost small locking protrusion 15
Until a, 15a engages with the large locking grooves 21, 21, the other small locking protrusions 15... and the small locking grooves 2
2. Engagement with... does not occur. Therefore, the outer portion of the engagement protrusion 12 can be smoothly inserted into the locking groove 7 without causing any impact when the small locking protrusion 15 and the small locking groove 22 engage with each other. Then, at the same time as the innermost small locking protrusions 15a, 15a and the dividing groove part 20 are separated, the large locking protrusion 19 is stopped by the inclined parts 23, 23, and the small locking protrusions 19 are stopped, as shown in FIG. The locking protrusions 15a, 15a are large locking grooves 21,
21 and the other small locking protrusions 15 engage with the small locking grooves 22, respectively, so the impact at that time caused the operator to notice that the board fixture 1 was temporarily held. can be known.

In this temporarily held state, as shown by the dashed line in FIG. 6a,1
1a, 6a, 11a, the end portion 2a of the board 2,
2a can be easily inserted, improving work efficiency and avoiding the possibility that the surface of the board 2 will be damaged during the insertion. In addition, when the boards 2... are temporarily attached to the base part 5, there may be defects in construction, such as boards that should be attached in a straight line, but are irregularly arranged, such as in a zigzag shape. If there is, remove the fastening member 4 at the necessary part and modify it. When it is finally confirmed that there are no defects, the large locking protrusion 19 and the large locking groove 21 are fitted together as shown in FIG. 3, and the board 2 becomes strong and stable. , will be fully installed. In addition, if the defect such as the irregular board state is relatively minor, the defect can be corrected in the temporarily held state, and in that case,
Even when using a board 2 which is mainly made of a soft material such as a heat insulating board and subjected to surface treatment, the surface of the board 2 may be damaged at the tips of both sides 11a and 11a of the holding plate 11. I never received it.

As mentioned above, the board mounting tool of the present invention is composed of a mounting member and a fastening member that can hold the board in two stages: a temporary holding state and a complete holding state. In addition to streamlining the installation process, defects in construction can be easily corrected prior to complete installation of the board, providing excellent flexibility in construction. Further, in the temporarily held state, the fastening member can be easily moved in the longitudinal direction, so that the front and rear fastening members can be connected without creating a gap at the connecting portion.

Note that the board mounting tool of the present invention can be used in a wide range of cases, such as when installing a heat insulating board on a wall surface, and when installing a board on a base part. Note that the attachment member may be attached to the base portion by adhesive means.
