Description

  The present invention relates to a ceiling board temporary fixing tool that allows an operator to easily attach a ceiling board by itself.

  It is usually necessary to install a large number of ceiling boards on the ceiling of a building. At the time of the installation work, it is necessary to install the ceiling boards against the gravity from below, and it is also a work at a slightly high place, which is efficient. It is a bad and dangerous task. A ceiling board is arrange | positioned along the field edge suspended, for example with the hanging tree from the beam, and is screwed and fixed in the part which overlaps with these field edges. Such a ceiling board may be doubled and attached depending on the necessity for soundproofing or heat insulation reinforcement.

  Similar to the floor, the shape and size of the ceiling are various. Usually, a ceiling having a shape according to the plan is configured by sequentially bonding a plurality of ceiling boards. The ceiling board which is a unit member constituting such a ceiling is not limited to a wooden board from the viewpoints of sound absorption and heat insulation, and a variety of other materials such as a gypsum board are also employed. In addition, the ceiling board is not uniform in terms of size, but many are relatively thin board materials that do not require strength like floor boards, and those of a slightly large size are also frequently used. Therefore, it is difficult to perform the installation work alone, and one worker of the ceiling board to be normally attached is supported by one worker and the other worker is supported by the other worker. Such a work mode causes an increase in work cost.

  Therefore, in order to solve the above problems, a ceiling board temporary fixing tool for temporarily fixing the ceiling board has been proposed. The first example is a board support that is locked to a ceiling bar and temporarily holds one end of the ceiling board (Patent Document 1). A second example is an attachment jig that is locked to a field edge and temporarily holds a side portion of a ceiling board (Patent Document 2). The third example is a ceiling board fixture using a fixture that is selectively used depending on two types of application locations (Patent Document 3). The fourth example is a ceiling board tensioning auxiliary tool and auxiliary metal fittings whose front surface is open, whose side surface is U-shaped and whose upper surface can be moved up and down (Patent Document 4).

  The operator attaches the ceiling board temporary fixing tool described above to a field edge or crosspiece close to one end of the ceiling board to be attached, and then lifts the ceiling board. The one end of the ceiling board is locked to the top, and the work can be performed in the procedure of fixing the ceiling board to the field edge with screws or the like. Therefore, if these ceiling board temporary fixing tools are used, it is certain that the operator can attach the ceiling board alone.

  However, the temporary fixtures of the above examples have various concerns as follows. In other words, since each of them is used by engaging with a field edge or a crosspiece of the ceiling portion, for example, when the same field edge is shared by adjacent ceiling boards, a situation where it is impossible or difficult to cope with may occur. Also, since the size of the field edge is not necessarily uniform, it is necessary to prepare a size corresponding to the size of the field edge. Also, there are some which are difficult or impossible to remove after the ceiling board is attached like the ceiling board fixture of Patent Document 3. In this case, a part of the fixture remaining between the field edge and the ceiling board causes unevenness on the lower surface of the ceiling board, and a part of the fixture remaining between adjacent ceiling boards is the part. There is also a possibility of generating a problem such as generating a gap in the surface.

  The present invention solves the above-mentioned problems of the prior art, and provides an easy-to-use and easy-to-configure ceiling board temporary fixture capable of easily and efficiently mounting a ceiling board alone. It is what.

1 of the present invention is a quadrilateral substrate portion having one or more locking holes penetrating between the front and back surfaces;
An auxiliary support plate part suspended from one end of the substrate part at an angle of about 90 degrees;
An introductory inclined plate portion extended from the other end of the substrate portion to a descending inclined state;
It is a ceiling board temporary fixture composed of

  According to a second aspect of the present invention, in the ceiling board temporary fixing tool according to the first aspect of the present invention, one or more hooks that hang from the lower surface of the base plate portion are configured.

  According to a third aspect of the present invention, in the ceiling board temporary fixing tool according to the first or second aspect of the present invention, the leading end of the auxiliary support plate portion is obliquely bent toward the substrate portion side to constitute the introduction portion.

  4 of the present invention is the ceiling board temporary fixture of the present invention 1, 2 or 3, wherein the side plate of the board portion is suspended downward by a dimension exceeding the thickness of the ceiling board, and the side plate An adjustment guide portion is configured which includes a slide guide plate extending from the lower end in parallel to the surface of the substrate portion and on the opposite side of the substrate portion.

  According to the ceiling board temporary fixing tool of 1 of the present invention, at the time of attaching the ceiling board, one or more ceilings are provided at the end or both ends or other parts farther from the part supported by the operator. It can be temporarily fixed using a board temporary fixing tool. Therefore, an operator can easily and efficiently attach the ceiling board alone.

  According to the ceiling board temporary fixing tool of 2 of the present invention, various tools such as an electric screwdriver are suspended from the hook of the ceiling board temporary fixing tool temporarily fixed as necessary during the ceiling board mounting operation. Therefore, troublesome operations such as placing and picking it up under each foot are eliminated, and efficient installation work can be performed. Further, when the work is performed until late in the evening or until night and the surroundings become dark, it can be used to illuminate the surroundings by suspending an electric lamp or the like on the hook.

  According to the ceiling board temporary fixing tool of the third aspect of the present invention, when the ceiling board mounting operation is started from the portion in contact with the wall, the ceiling board temporary fixing tool is temporarily attached to the auxiliary support plate portion of the ceiling board temporary fixing tool temporarily fixed to the wall surface. The tip of the ceiling board can be easily inserted, and the ceiling board installation work can be started more smoothly.

  According to the ceiling board temporary fixing tool of 4 of the present invention, when the dimensions of the ceiling board are adjusted at the site, it is possible to reduce the burden on the operator and perform it efficiently.

  The ceiling board temporary fixing tool of the present invention basically includes a substrate portion having an engaging hole, an auxiliary support plate portion configured at one end thereof, and an introduction inclined plate portion extended from the other end of the substrate portion. It is composed.

  The substrate portion is basically a quadrilateral plate-like member as viewed from above, and normally a metal strip member having a width of 10 mm, a length of 50 mm, and a thickness of 1 to 2 mm is adopted as it. Is appropriate. Of course, it is possible to adopt a relatively large metal plate having a width of about 200 mm and a length of about 500 mm, and this size can be freely determined according to the convenience of the user. Note that the material of the substrate portion is not limited to metal as long as necessary strength can be secured.

  The locking hole is a hole element used when locking means such as a screw or a wood screw is screwed and fixed to an object to be temporarily fixed therethrough. Temporary fixing of this ceiling board temporary fixing tool shall be done with screws etc. using the part where screws etc. will be screwed in to fix the ceiling board, so as not to cause unnecessary screw holes etc. in the target ceiling board Therefore, the locking hole should be configured as a hole having a dimension capable of using a screw for a ceiling board to be temporarily fixed. The number should be determined appropriately according to the size of the substrate portion.

  The auxiliary support plate portion is a component that is suspended at an angle of approximately 90 degrees from one end of the substrate portion, and may be configured to be joined to the corresponding end portion of the substrate portion. It is appropriate to bend the part. This auxiliary support plate portion, when starting the installation work of the ceiling board from the part in contact with the wall, with this part up, and a gap slightly exceeding the thickness of the target ceiling board is provided above this part The ceiling board temporary fixing tool provided with the above is a part to be used by temporarily fixing it to the wall surface, and temporarily supports the ceiling board inserted thereon, so that the purpose can be achieved appropriately What is necessary is just to comprise to a dimension. For example, the width is the same as that of the substrate part, and a length of about 10 to 20 mm is usually sufficient. The angle between the substrate portion and the substrate portion is suitably about 90 degrees for the above purpose, but any angle before and after that is applicable.

  Moreover, it is preferable that the front end of the auxiliary support plate portion be bent obliquely toward the substrate portion side to constitute the introduction portion. By configuring in this way, when the ceiling board temporary fixture is temporarily fixed to the wall surface, it becomes possible to easily insert the tip of the target ceiling board onto the auxiliary support plate part, This is because a smooth ceiling board mounting operation can be started.

  As described above, the introduction inclined plate portion is a component extended from the end portion of the substrate portion on the side opposite to the auxiliary support plate portion to a downward inclined state. The purpose of the downward inclination is to guide the one end of the target board well when inserting one end of the target ceiling board onto the board part from the end side, and it is usually slightly inclined downward. A degree angle is sufficient.

  A hook that hangs down from the lower surface of the substrate portion can be formed. The number of hooks does not matter. You can configure as many as you need. However, when the substrate size is about 10 mm wide and 50 mm long, it is actually inconvenient to provide two or more, and it is appropriate to provide a plurality of substrates when the size of the substrate is larger than that. . In addition, the shape of the hook is generally the shape of a generally used fishhook. However, the shaft-shaped base portion prevents mutual interference when locking various tools to the hook portion. For the purpose of making it difficult to occur, it is appropriate to make it sufficiently longer than the length of the auxiliary support plate.

  The material of the hook is appropriately a metal from the viewpoint of necessary strength in many cases, but is not limited to a metal as long as it has a strength suitable for the purpose. Further, the means for coupling the hook to the substrate portion is not limited to a specific one. Means such as welding or screwing can be freely employed.

  In addition to the above-described constituent elements, auxiliary elements can be added to the substrate portion. It is needless to say that the addition of the largest number of elements should be limited to an appropriate limit because it may cause the above important functions to be hindered.

  As a specific example of the auxiliary element, a side plate suspended from the side of the board part to a lower side slightly exceeding the thickness of the ceiling board, and a slide guide plate extending in parallel to the surface of the board part from its lower end There is an adjustment guide.

  For example, when a ceiling board is attached to the wall, the size may be determined on site. In such a case, the adjustment guide part can be used. The board part is brought into contact with the corresponding part of the ceiling board previously attached and temporarily fixed, and the slide guide is moved forward and backward while a part of the side part of the ceiling board attached on the site is intruded on the slide guide plate. It is used to check the dimensions while pressing against the corresponding part to be attached. Cut the unnecessary part of the target ceiling board with a saw and repeat the same procedure. This is repeated until the ceiling board is accurately placed in the corresponding part, but by using this adjustment guide section, the forward and backward movement of the ceiling board at this time is performed without feeling a burden on the operator. It will be possible to do.

  As a specific example of the auxiliary element, there is a handle extended obliquely downward from the side portion of the substrate portion.

  Therefore, according to the ceiling board temporary fixing tool of the present invention, a single operator can easily attach the ceiling board by using it as follows.

  First, the ceiling board temporary fixing tool is temporarily fixed to the upper part of the wall surface on the attachment start side so that the auxiliary support plate portion side faces upward. This temporary fixing is performed by screwing a screw or the like through a locking hole opened in the substrate portion. When temporarily fixing in this way, the gap between the upper surface of the auxiliary support plate portion and a field edge or the like which is a support material of the ceiling board is left slightly wider than the thickness of the ceiling board. When the width of the ceiling board is relatively wide, it is preferable to attach temporary ceiling board fasteners to a plurality of locations on the upper surface of the wall so that the ceiling board can be supported at a plurality of locations according to the width. These ceiling board temporary fixing tools are the same when temporarily fixed to the ceiling portion described later, but are arranged at positions that overlap with the pillars or the studs on the wall surface so that the temporary fixing can be ensured. .

  After the ceiling board temporary fixing tool is temporarily fixed in this way, when the hook is formed on the board portion, the electric driver used for the temporary fixing (the electric screwdriver can be used for screwing the screw) Although it is not a condition, it is usual to use this, and it is also realistic from the viewpoint of work efficiency.

  Next, the ceiling board is lifted, and one end of the ceiling board is inserted and placed on the auxiliary support plate portion of the ceiling board temporary fixing tool attached to the wall surface. In the case where the leading end of the auxiliary support plate part is bent obliquely toward the board part side to form the introduction part, at this time, even if the corresponding end part of the ceiling board is bent slightly, The corresponding end portion is easily guided to the introduction portion, and is pushed in until it comes into contact with the wall surface.

  After one end of the ceiling board is thus supported by the auxiliary support plate portion, the electric driver is removed from the hook, and the portion overlapping the field edge of the ceiling board is sequentially fixed with screws. It is appropriate to start screwing from a site away from the wall surface. After the ceiling board is fixed in a manner leaving a part near the end opposite to the wall surface, or at another appropriate stage, a new ceiling board temporary fixing tool is attached to the wall surface of the ceiling board. Temporarily fix it on the opposite end. This temporary fixing is performed in a state in which the introduction inclined plate portion is directed in a direction opposite to the wall surface, and a part of the substrate portion and the introduction inclined plate portion are protruded from the ceiling board.

  The ceiling board temporary fixing tool temporarily fixed to the end of the ceiling board opposite to the wall surface to be installed is not limited to the above, but at any stage prior to the next ceiling board installation work due to work convenience. It may be temporarily fixed. If this is temporarily fixed at an early stage, the remaining screw fixing work for fixing the ceiling board is subsequently performed. After this is temporarily fixed, the next ceiling board installation work may be started before all the remaining screwing operations are completed, and the remaining screwing may be performed later for convenience.

  When the next ceiling board mounting operation is started, as described above, when the hook is formed on the board portion, the electric driver is suspended from the hook and then the operation is started.

  In the same way as described above, the operator lifts a new ceiling board and temporarily mounts one end of the ceiling board on the end opposite to the wall surface of the previously installed ceiling board. Support. This support is performed by pushing and inserting the one end portion from the introduction inclined plate portion of the ceiling board temporary fixture to a part of the substrate portion, and placing the end portion thereon. Thereafter, as described above, the electric screwdriver is removed from the hook and the required portion is screwed using the ceiling board temporary fixing tool while supporting one end portion thereof on the ceiling board temporary fixing tool. Thereafter, as described above, at an appropriate stage, another ceiling board temporary fixing tool is temporarily fixed to the opposite end portion of the current target ceiling board in the same manner as that previously fixed.

  Thereafter, the same work cycle is repeated, and the worker can easily and independently fix the ceiling board to all necessary areas of the ceiling.

  Note that the temporarily fixed ceiling board temporary fixing tool can be removed at any stage after the ceiling board is secured by screws or the like. If it is removed at the earliest possible stage, it can be used repeatedly during the ceiling board mounting operation, and the number of ceiling board temporary fixing tools to be prepared can be reduced. After removing the ceiling board temporary fixing tool, if the screw for fixing the ceiling board is screwed into the temporary fixing screw hole and used for fixing, the useless hole does not remain on the ceiling board.

  Therefore, if the ceiling board temporary fixing tool of the present invention is used, the ceiling board can be easily and efficiently attached by one worker. In addition, if the ceiling board temporary fixing tool is configured with a hook, even if it becomes dark after work such as in the evening or at night, a lighting means such as an electric light is hung on the hook to illuminate the surrounding area. Can work while.

  The ceiling board temporary fixing tool 1 according to the first embodiment is a board portion having two oblong holes 14 and 14 which are elongated and rectangular as shown in FIGS. 1 (a), 2 (a) and 2 (b). 10, an auxiliary support plate portion 11 configured by bending one end portion of the substrate portion 10 at a right angle to be in a suspended state, and an introduction inclined plate portion 12 configured by bending the other end portion in a downward inclined state of about 20 degrees. And a hook 13 fixed at the center of the substrate 10 is a basic component.

  As shown in FIGS. 1 (a) and 2 (a), the hook 13 is arranged by fixing the shaft-like base portion to the center portion of the substrate portion 10 by welding. The shaft-like base portion is configured to be sufficiently longer than the hanging length of the auxiliary support plate portion 11 so that mutual interference is less likely to occur when an electric driver D or the like described later is locked to the hook portion. Further, as shown in the figure, the hook portion is formed by rounding in a semicircular shape toward the auxiliary support plate portion 11 side.

  The substrate portion 10 is made of a metal plate material having a width of about 10 mm, a length of about 50 mm, and a thickness of about 2 mm. The auxiliary support plate portion 11 is bent at one end by 90 degrees and suspended about 10 mm. As described above, the introduction inclined plate portion 12 is configured in a descending inclined state by bending the other end side at an angle of about 20 degrees. Thus, in the first embodiment, the substrate portion 10, the auxiliary support plate portion 11, and the introduction inclined plate portion 12 are integrally formed of the same metal plate material.

  The auxiliary support plate portion 11 is configured such that the lower end portion side thereof is obliquely bent toward the substrate portion 10 side to constitute the introduction portion 11a.

  Therefore, according to the ceiling board temporary fixing tool 1 of the first embodiment, when the ceiling board P is attached to the ceiling, it can be usefully used as follows.

  First, as shown in FIG. 1 (a), the ceiling board temporary fixing tool 1 is temporarily fixed to the upper part of the wall surface W with the auxiliary support plate part 11 facing upward. At that time, it is assumed that the gap between the upper surface of the auxiliary support plate portion 11 and the lower surface of the field edge T has a margin with respect to the thickness of the ceiling board P to be attached. Since the width of the ceiling board P is considerably wider than the width of the ceiling board temporary fixture 1, the ceiling board temporary fixture 1 is temporarily fixed to both sides thereof as shown in FIG.

  Needless to say, these ceiling board temporary fixing tools 1 should be disposed in a portion overlapping the field edge T in order to secure temporary fixing. This temporary fixing is performed using a screw B used for fixing the ceiling board P, and the electric screwdriver D is also used in the first embodiment for screwing. The temporary fixing of the ceiling board temporary fixing tool 1 is performed by screwing the screws B and B into the locking holes 14 and 14 opened in the substrate portion 10 respectively.

  After temporarily fixing the pair of ceiling board temporary fixtures 1 and 1 in this manner, the electric driver D used for the temporary fixing is suspended on the hook 13 of the ceiling board temporary fixture 1 on either side in preparation for the subsequent work. Keep it down. This suspension can be performed using a strap attached to the electric driver D. When the work is continued even after dark in the evening or at night, an electric lamp (not shown) is hung on the hook 13 of the other ceiling board temporary fixing tool 1 to illuminate the work area. To do.

  Next, the ceiling board P to be attached is lifted, and as shown in FIG. 1 (b), the upper ends of the auxiliary support plate portions 11 of the ceiling board temporary fixtures 1, 1 on both sides with one end attached to the wall W. Insert and mount. Since the introduction part 11a which inclines below is formed in the front-end | tip part of this auxiliary | assistant support plate part 11 and 11, even if the applicable edge part of this ceiling board P is bent slightly and it hangs down, it mounts on it easily. If the operator pushes while supporting this, the corresponding end portion is guided to the auxiliary support plate portions 11 and 11 and can move until it contacts the wall surface W.

  Thereafter, the electric driver D is removed from the hook 13 of the ceiling board temporary fixing tool 1 and a portion overlapping the field edge T of the ceiling board P is used with screws B, B. Fix it. In Example 1, after fixing the ceiling board P except for two places near the end opposite to the wall surface W, the ceiling board temporary fixtures 1, 1 temporarily fixed to the wall surface W are removed, When it is necessary to fix the screw at the position where the auxiliary support plate portions 11 and 11 face each other, after that, as shown in FIG. 1 (c), the vicinity of the end opposite to the wall surface W The ceiling board temporary fixing tool 1 is temporarily fixed at each of the two locations.

  The ceiling board temporary fixtures 1, 1 are located at the above two positions of the ceiling board P, that is, at two positions opposite to the wall surface W of the ceiling board P that is not screwed. Temporarily fasten near the end. Temporarily fixing the introduced inclined plate portion 12 and a part of the substrate portion 10 to a state in which they protrude from the end portion of the ceiling board P. These temporary fixings are performed by screwing screws B and B into the locking holes 14 and 14 of the substrate part 10 in the same manner as described above. This is performed using the electric driver D.

  After temporarily fixing the ceiling board temporary fixtures 1 and 1 in this way, the electric driver D used for fixing the ceiling board P and temporarily fixing the ceiling board temporary fixtures 1 and 1 is as shown in FIG. In preparation for the subsequent work, the ceiling board temporary fixtures 1 and 1 are hung on one of the hooks 13. When the work is performed in the dark, such as at night, as described above, the electric lamp hung on the hook 13 of the other temporary fixing of the ceiling board 1 is temporarily placed near the new work area. The suspended ceiling board temporary fixtures 1 and 1 are replaced with other hooks 13 of the ceiling board temporary fixtures 1 and 1 to illuminate a new work area.

  Thereafter, as described above, the operator lifts a new ceiling board P, and temporarily fixes one end of the ceiling board P to the end of the ceiling board P attached in advance as shown in FIG. 1 (c). The ceiling board temporary fixtures 1 and 1 are supported. This support is performed by pushing and inserting the one end portion from the introduction inclined plate portion 12 of the ceiling board temporary fixtures 1 and 1 to a part of the substrate portion 10 and placing the end portion thereon. Thereafter, as described above, the electric driver D is removed from the hook 13 and used while the one end portion is supported by the board portion 10 of the ceiling board temporary fixing tool 1, 1. Screw the required part. This screwing is performed in the same manner as described above.

  Thereafter, at the same stage as described above, the temporarily fixed ceiling board temporary fixtures 1 and 1 are removed, and these are described in advance at the opposite end of the ceiling board P that is currently the object. Temporarily fix in the same manner as the temporary fix. In addition, the ceiling board temporary fixing tool 1 that suspends the electric lamp is temporarily fixed as it is, or, as described above, from the relationship with the illumination area, the electric lamp is newly temporarily fixed to the ceiling. It is also possible to change the hook 13 of the temporary board fixing tool 1 and remove it.

  Thereafter, the same work cycle is repeated, and the operator can easily and independently fix the ceiling board P to all necessary areas of the ceiling.

  As shown in FIGS. 3A, 3B, 3C, and 3D, the ceiling board temporary fixing tool 1 according to the second embodiment is provided on the side of the board portion 10 with the target ceiling board P. An adjustment guide portion 16 is provided which includes a side plate 16a that is suspended downward by a dimension slightly exceeding the thickness, and a slide guide plate 16b that extends in parallel to the surface of the substrate portion 10 from its lower end. All other configurations are the same as in the first embodiment.

  Therefore, the ceiling board temporary fixing tool 1 of the second embodiment can be used basically in the same manner as in the first embodiment and can provide the same effect. By having comprised, it can be used as follows and the corresponding outstanding effect can be acquired.

  The ceiling board P may not be attached with the original size at the wall or the like. Even if this is the case, it is not always realistic to cut to an appropriate dimension in advance, and the size may have to be determined by an on-site matching operation. In this case, the ceiling board P is abutted while sliding it to a predetermined part such as a wall surface several times, the dimensions are confirmed and cut, and the cut ceiling board P is slid again and abutted to confirm the dimensions. If there is an error, the work of cutting that is performed.

  The adjustment guide 16 can be used effectively in such a case. As shown in FIG. 3 (d), the ceiling board temporary fixing tool 1 is temporarily fixed to a field edge T or the like with a screw B in a state where the direction of the adjustment guide portion 16 is aligned with the sliding direction of the ceiling board P. The ceiling board P is slidably placed on the slide guide plate 16b of the adjustment guide unit 16. Thereafter, as described above, the ceiling board P is slid, the required size is confirmed, and the work for cutting the ceiling board P is performed. Since this work is performed in a state where the target ceiling board P is placed on the slide guide plate 16b of the adjustment guide part 16, the work becomes light and the burden on the operator can be reduced. Therefore, it is possible to focus on more accurate dimensional alignment.

  As shown in FIGS. 4A, 4B, and 4C, the ceiling board temporary fixing tool 1 according to the third embodiment is configured such that a handle 17 is formed on the side portion of the substrate portion 10, and this handle is provided. Reference numeral 17 denotes an elongated rectangular plate-like member extending obliquely downward from the side portion of the substrate portion 10 as shown in FIG. The ceiling board temporary fixing tool 1 of the third embodiment is the same as that of the first embodiment in all other configurations.

  Therefore, the ceiling board temporary fixing tool 1 of the third embodiment can be used basically in the same manner as in the first embodiment and achieve the same effect. In addition, the handle 17 is configured. Therefore, the ceiling board temporary fixing tool 1 can be easily handled by grasping it.
