Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ruler for facilitating the marking out of a base edge when fixing a ceiling board with screws.

[0002]

[Prior art]

 Conventionally, when a ceiling board such as a gypsum board is to be laid on the ceiling, first the positions of the field edges are measured on the four corners of the room with a measure, etc., and the ceiling boards are stopped so that they do not fall onto the field edges of the ceiling. Then, as shown in FIG. 7, one end of the black ink thread 1 is aligned with the position of the field edge obtained as described above, and the black ink bottle 2 is held to align with the position of the field edge of the other end. He struck a screw on the position and stopped the ceiling board.

[0003]

[Problems to be solved by the device]

 However, if the ceiling board is stretched and screwed as in the conventional method, if the ceiling board is stretched, the position of the ceiling margin will not be known. It takes a lot of time to put on and make a note of the position, and the work of fixing the ceiling board to the field edge and then marking out it is because each field edge is marked out vertically and horizontally. It is time-consuming and troublesome, and not only is the ink sticking to the ceiling surface, but it can become dirty.Since these positioning operations are performed with the top facing up, the neck and other parts are very tiring and difficult to do. Of.

[0004]

[Means for Solving the Problems]

 The problems to be solved by the present invention are as described above, and in order to solve the problems, an alignment bar is provided on one side of a plate which is a fraction of the size of the ceiling board fixed with screws at the field edge. A drawing hole is provided in the center of the plate at a position corresponding to the pitch from the edge to the field edge.

[0005]

With the above-described structure, the screw-marking ruler 10 is placed on the ceiling board 7 placed on the floor, and the crosspiece 10b and the vertical side 10e are aligned with the end surface of the ceiling board 7 to make the ceiling board. A line is drawn on the vertical side 10e, the horizontal side 10f, and the drawing holes 10c and 10d on the 7 according to the type of the field edge 4, and the stake-out stakeout ruler 10 is moved in parallel and symmetrically to move it on the ceiling board 7. If this is fixed to the ceiling by drawing all lines, the screw fixing position and the field edge will match, and the work time for marking out can be shortened.

【Example】

 The problems to be solved and the means for solving the present invention are as described above. Next, a specific configuration of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a perspective view of a ceiling board with a ceiling board stretched over the edge of the ceiling, Fig. 2 is a perspective view of the marking ruler for screwing according to the present invention seen from below, Fig. 3 is the same plan view, and Fig. 4 is vertical and horizontal. Fig. 5 is a plan view of the markings for screwing on the field edges provided on the floor, Fig. 5 is a plan view of marking the fields on one side for screwing, and Fig. 6 is the marking process. FIG.

In FIG. 1, hanging trees 3.3 ... Are hung vertically via a beam or a hanging tree receiver, and the hanging trees 3.3. On the other hand, the peripheral edges 5 are fixed to the upper four sides of the wall 6 at fixed intervals, and the ceiling boards 7 made of gypsum board are attached to the peripheral edges 5 on the peripheral edges 5. It is fixed to 4 ... with screws 9.

The present invention is to make it easy to recognize the position where the screw 9 is to be hit. As shown in FIG. 2, the marking ruler 10 for screw hitting is a ceiling board at the back end of one side of the plate 10a. A bar 10b having a thickness substantially the same as that of No. 7 is fixed, and elongated drawing holes 10c and 10d are opened in a cross shape in the center. However, the marking-out ruler 10 for screwing may be a wooden plate such as veneer, may be made of metal or synthetic resin, and the crosspiece 10b may be a vertical side or a horizontal side. It may be bent at that position instead of. The horizontal length L1 of the screw-marking ruler 10 is half the horizontal length L5 of the ceiling board 7 (L5 = 2 × L1). The length L2 in the vertical direction from the inside is half of the length L6 in the vertical direction of the ceiling board 7 (L6 = 2 × L2), that is, one-quarter the size of the ceiling board 7 and the crosspiece 10b. With the added size, the marking-out ruler 10 for screwing is moved by changing the position four times so that a marking-out line can be drawn on the ceiling board 7. However, depending on the indexing of the ceiling board, the size may be one-third, one-sixth, or one-eighth according to the indexing.

This marking is at the position of the field edge 4, and in the present embodiment, it is possible to perform marking even when there are two indexing conditions for the field edge 4. For example, when the field edge 4 is made of wood. Is located so that the field edge 4 is located in each of the horizontal quadrant and the vertical half position of the ceiling board 7. In order to match the field edge 4, the screw-marking ruler 10 is in the center. The position of the wire drawing hole 10c is set such that the length L3 from the end side is half (L1 = 2 × L3) of the horizontal length L1 of the screw marking blackout ruler 10. Further, in the case of a steel field edge, the field edge 4 is located at every one-third position of the ceiling board 7 in the vertical direction, so that the field edge 4 corresponds to this field edge. The distance L4 from the inside of the bar 10b of the screw-marking ruler 10 is one-third the length of the ceiling board 7 in the vertical direction (L6 = 3 × L4), and the wire drawing hole 10d is opened in the longitudinal direction. It is.

When the marking-out ruler 10 for screwing configured as described above is used, it is not necessary to carry out the marking-out operation upward, and as shown in FIG. In the case where they are provided at equal intervals vertically and horizontally like a field edge, as shown in FIG. 4, the inside of the bar 10b of the screw-marking ruler 10 is applied to the longitudinal side of the ceiling board 7, When the vertical side 10e is aligned with the vertical side of the ceiling board 7, the vertical side 19e and the horizontal side 10f of the screw-marking ruler 10 are at the position of a quarter of the ceiling board 7, and the central drawing hole. 10c is a horizontal quadrant, and by drawing a line there, it can be aligned with the position of the field, and the marking-out ruler for screwing 10 is moved in parallel and symmetrically, and the remaining ceiling board is reached. If you draw a line on each side, the ink that matches the position of the field edge It can be put out. Further, in the case of only one direction such as a steel edge, as shown in FIG. 5, the inside of the bar 10b of the screw-marking ruler 10 is applied to the long side of the ceiling board 7, Align the vertical side 10e with the vertical side of the ceiling board 7 and draw a line from the drawing hole 10d opened in the longitudinal direction of the marking ruler 10 for screwing to move in parallel and symmetrically, and move it on the ceiling board respectively. If you draw a line, you can mark it according to the position of the field.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. That is, it is a plate that is a fraction of the size of the ceiling board, so it is easy to carry, and since the drawing hole is only opened at the specified position, it can be easily made and can be used many times. Yes, it can be adapted to the indexing of several types of ties, resulting in a low-cost rule. In addition, the marking work could be easily performed in a downward direction, and the time and fatigue could be shortened. Furthermore, it can be used not only for ceiling boards but also for wall boards.
