Description

  The present invention is used in conjunction with a temporary ceiling board fixture that is used by an operator to install the ceiling board alone, facilitating the installation of the ceiling board by itself, and in doing so temporarily for some other work. The present invention relates to a ceiling board auxiliary support device that enables support of a typical ceiling board.

  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. For example, the ceiling board is arranged in a joined state at a field edge attached to a field edge suspended from a beam by a suspended tree, and screws or the like are screwed and fixed to portions of the area overlapping 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 mounting work alone, and one worker is supposed to support one end of the ceiling board to be normally mounted, and the other worker supports the other end. Such a work mode is a factor of 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.

  Therefore, from the viewpoint of solving these problems and providing an easy-to-use and easy-to-configure ceiling board temporary fixture capable of easily and efficiently mounting the ceiling board alone, the applicant of the present invention stated that A quadrangular substrate part having one or more locking holes penetrating therethrough, an auxiliary support plate part suspended from one end of the substrate part at an angle of about 90 degrees, and a downward inclination from the other end of the substrate part The ceiling board temporary fixing tool comprised with the introductory inclination board part extended to the state "was proposed (patent document 5).

  The technique of this patent document 5 is very excellent, and it is considered that there is no problem in itself. However, the applicant of the present application will provide means for further improving the usability and for temporarily holding the ceiling board in the case where some other work is required when the ceiling board is installed using the same. Came to consider it more convenient.

  Item 2 of the present invention is a ceiling board auxiliary support device according to item 1 of the present invention, in which a receiving part for temporarily placing an end of the ceiling board is provided at the lowermost part of the slide guide part. is there.

  A third aspect of the present invention is the ceiling board auxiliary support device according to the first or second aspect of the present invention, wherein the slide guide portion is suspended in a state inclined from the front end of the end portion mounting portion to the rear end side. is there.

4 of the present invention is the ceiling board auxiliary support device of 1 of the present invention, wherein the locking portion includes a short hanging piece in which one end of a horizontal metal strip is bent downward, and the metal strip The top plate piece extended from the upper end of the short hanging piece to a position exceeding the width of the horizontal member intersecting the field edge of the ceiling of the building, and the metal strip corresponding to the upper end of the short hanging piece of the top plate piece It is composed of a long hanging piece that is bent downward from the end opposite to the end, and is suspended beyond the thickness of the horizontal member and the thickness of the target ceiling board.
The end mounting portion is configured as a horizontal piece that is bent so that the lower end of the metal strip constituting the long hanging piece is below the top plate piece and parallel to the top plate piece. ,
The slide guide part is a hanging piece bent so that the front end of the metal strip constituting the top plate piece which is the end placement portion faces downward and the inner angle formed by the top plate piece and this becomes an acute angle. It is composed.

  5 of the present invention is the ceiling board auxiliary support device of 4 of the present invention, wherein the metal strip constituting the slide guide portion is bent at the lower end of the slide guide portion, and the front end thereof is the end portion mounting portion. The receiving portion is configured to be located on the same side as the front end.

According to the ceiling board auxiliary support of 1 of the present invention, when the ceiling board is attached using the ceiling board temporary fixing tool, when one end is supported by the ceiling board temporary fixing tool, the other end is supported. Thus, the part can be supported, and the installation work of the ceiling board becomes easier.
More specifically, when installing the ceiling board, place the end farther than the part supported by the worker on the introduction inclined plate using one or more ceiling board temporary fixing tools. Then, the end portion closer to the operator can be mounted on the end portion mounting portion of the ceiling board auxiliary support tool 1 of the present invention to fix the ceiling board to the field edge. . In this state, the top surface of the ceiling board is not completely in contact with the field edge, but it is in a very close state, and the operator is free of both hands at this time even if working alone. Therefore, it is possible to easily perform the attaching operation to the field edge while slightly pushing up the ceiling board.

  According to the ceiling board auxiliary support tool of 2 of the present invention, when one end of the ceiling board is supported by the introduction inclined plate portion of the ceiling board temporary fixing tool, the other end is positioned slightly lower using the receiving portion. Can be temporarily placed on and supported. Or, conversely, one end of the ceiling board is first placed on the receiving part of the ceiling board auxiliary supporter of the present invention 2 and the other end is placed on the introduction inclined plate part of the ceiling board temporary fixing tool. It is also possible. In this case, it is necessary to temporarily pull the ceiling board toward the ceiling board auxiliary support when inserting the other end into the introduction inclined plate portion. However, the ceiling board auxiliary support swings in that direction. Since this is possible, there is no inconvenience in this regard. If it is not necessary to place the corresponding end of the ceiling board on the receiving part of the ceiling board auxiliary support, the end simply slides up the end and the end slides on the slide guide. It moves to the upper end placement part and can be placed on it. The attachment of the ceiling board to the field edge from this state is as described above.

  According to the ceiling board auxiliary support device of the present invention 3, when the ceiling board having the other end supported by the inclined inclined plate portion of the ceiling board temporary fixing device is to be placed on the uppermost end placement portion When the corresponding end portion is lifted so that the other end portion mounted on the introduction inclined plate portion rotates about the rotation center, the corresponding end portion is placed on the front side of the lower end of the slide guide portion. Needless to move it so that it comes into contact, it comes into contact with the front side of the ceiling board, and the ceiling board auxiliary support is rotated (swinged) about the horizontal member to which it is locked. When the slide rises and rises to the height of the end placement portion, the ceiling board auxiliary support is placed on the end placement portion as the ceiling board auxiliary support returns (returns and swings). . When the receiving portion is configured at the lower end of the slide guide portion, the other end portion of the ceiling board having one end placed on the introduction inclined plate portion of the ceiling board temporary fixing tool is in a state where it does not turn backward. It can be placed on the receiving portion.

  According to the ceiling board auxiliary supporter 4 of the present invention, the configuration of the ceiling board auxiliary supporter 1 of the present invention can be easily configured by appropriately bending a single metal strip. It can be used as well.

  According to the ceiling board auxiliary support 5 of the present invention, it is possible to simply fold a metal strip and configure it with a receiving portion, and it can be used in exactly the same way as 4 of the present invention. it can.

  The ceiling board auxiliary support device of the present invention is configured to have a locking portion that locks on a horizontal member that intersects the field edge of the building ceiling portion so as to be swingable in a direction intersecting with the horizontal member, and immediately below the locking portion. An end placement portion for placing the end portion of the ceiling board, and a slide guide portion that is suspended from the front end of the end placement portion and guides the end portion of the ceiling board to the end placement portion. A quadrangular substrate portion having one or more locking holes penetrating between the front and back surfaces, and an auxiliary support plate portion suspended from one end of the substrate portion at an angle of about 90 degrees; The ceiling board temporary fixing tool configured to include an introduction inclined plate portion extended in a downward inclined state from the other end of the substrate portion.

  The locking portion, the end placement portion, and the slide guide portion of the ceiling board auxiliary support tool can be integrally configured by bending a band-shaped metal member.

  For example, the end of the horizontal band-shaped metal member is bent downward to form a short hanging piece, and a portion separated from the bent portion by a width dimension slightly exceeding the width of the horizontal member to be locked Is bent downward in the same manner to form a long long hanging piece. A portion connecting the short hanging piece and the upper end of the long hanging piece is a top plate piece, and the short hanging piece, the top plate piece, and the long hanging piece constitute the locking portion. The long hanging piece has a hanging dimension slightly exceeding the total dimension of the height dimension of the horizontal member to be locked and the thickness dimension of the ceiling board to be placed, and the top plate piece is positioned above the lower end thereof. A horizontal piece that is bent so as to be parallel to the top plate piece and extends in parallel with the top plate piece thus formed is defined as the end placement portion. This horizontal piece, which is an end placement portion on which the end portion of the ceiling board is placed, extends to a position substantially below the short hanging piece, and is bent and drooped again at this position. This hanging piece constitutes the slide guide portion.

  As described above, the ceiling board auxiliary support of the present invention can be configured by bending a band-shaped metal member. Of course, the ceiling board auxiliary support device of the present invention can be formed by using plastics made in addition to the above-described band-shaped metal member.

  The hanging piece that constitutes the slide guide portion may have a structure in which the tip of the horizontal piece that constitutes the end portion placing portion is bent at a right angle and suspended. It is preferable that the inner angle formed by the horizontal piece constituting the mounting portion is an acute angle, that is, a rearwardly inclined hanging piece inclined toward the rear end side of the horizontal piece.

  Moreover, it is preferable that the lower end of the above slide guide part is configured with a receiving part for temporarily placing the end part of the ceiling board. This is because, as described above, in the case of being constituted by a band-shaped metal member, the lower end of the hanging piece constituting the slide guide portion is bent in the same direction as the front end side of the horizontal piece constituting the end portion placing portion. And configure. The receiving portion is configured in an inclined state in parallel with the horizontal piece constituting the end portion mounting portion or a slightly elevated tip side.

The ceiling board temporary fixing tool used together with the ceiling board auxiliary support tool is briefly described as follows.
As described above, this is basically made up of a substrate portion having a locking hole, an auxiliary support plate portion formed 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 employs a metal strip member. The size can be determined freely 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 performed with a screw or the like using a part where a screw or the like is to be screwed in order to fix the ceiling board. Therefore, the locking hole is a ceiling board to be temporarily fixed. It is configured as a hole of a size that can be used with a screw for use.

  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 Configure to dimensions.

  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 angle of the descending inclination may be set to such an extent that the one end can be satisfactorily guided when the one end of the target ceiling board is inserted onto the substrate from the end side.

  A hook that hangs down from the lower surface of the substrate portion can be formed. The shape of the hook is suitably a generally fish-shaped hook that is generally used, but the shaft-like base portion causes mutual interference when locking various tools to the hook portion. For the purpose of making it difficult, it is appropriate to make it sufficiently longer than the hanging length of the auxiliary support plate portion.

  In addition to the above-described constituent elements, auxiliary elements can be added to the substrate portion.

  Therefore, the ceiling board auxiliary support tool of the present invention can be used as follows together with the above ceiling board temporary fixing tool.

First, the usage of the ceiling board temporary fixing tool will be outlined.
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 is directed upward. This temporary fixing is performed by screwing a screw or the like through a locking hole opened in the substrate portion. At this time, a 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. It is preferable that ceiling board temporary fixtures are attached 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 of the ceiling board.

  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. If the leading end of the auxiliary support plate part is bent obliquely toward the substrate part side to constitute the introduction part, even if the corresponding end part of the ceiling board is slightly lowered due to bending or the like, the corresponding end part is It is easily guided by the introduction part and can be pushed in until it comes into contact with the wall surface.

  Thereafter, for example, an electric screwdriver is used to sequentially fix the portions overlapping the edge of the ceiling board 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 portion 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 fasten 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.

  In the same manner as described above, for the next ceiling board mounting operation, the operator lifts a new ceiling board and temporarily fixes one end of the ceiling board to the end opposite to the wall surface of the previously installed ceiling board. Support the ceiling board temporary fixture. 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, a screwing of a required portion is performed using the electric screwdriver while one end portion is supported 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 of the current target ceiling board in the same manner as that previously fixed.

  Thereafter, the ceiling board can be fixed to all necessary areas of the ceiling sequentially by repeating the same work cycle.

  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 as early as possible, 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.

  As described above, when the ceiling board auxiliary support device of the present invention is attached to the ceiling board using the ceiling board temporary fixing tool, when the one end is supported by the ceiling board temporary fixing tool, the other end is supported. Thus, the ceiling board can be mounted more easily by supporting the portion.

  This will be explained in order. As described above, 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. The ceiling board temporary fixing tool is attached to a plurality of locations on the upper surface of the wall so that it can be supported at a plurality of locations according to the width of the ceiling board. Before and after this, the ceiling board auxiliary support tool is locked to a horizontal member such as a cross bar at a distance of one ceiling board from the wall surface using the locking portion. Naturally, at this time, the ceiling board auxiliary support tool is set so that the front end of the end portion mounting portion faces the wall surface side.

  After this, the operator lifts the ceiling board, and the auxiliary support plate part of the ceiling board temporary fixing tool attached to the wall surface as described above, the end part farther from the part of the ceiling board being gripped by the operator Insert it on top of it. The ceiling board is pushed in until the end portion inserted and placed on the auxiliary support plate portion comes into contact with the wall surface. Thereafter, the other end of the ceiling board is placed on the end placement portion of the ceiling board auxiliary support that is locked to a horizontal member such as a crosspiece as described above. Since the slide guide portion is suspended from the front end of the end placement portion, the other end of the ceiling board is simply lifted up while the other end is slid on the front surface of the slide guide portion. It will be guided to the mounting part. At this time, the ceiling board auxiliary support swings (rotates) around the horizontal member locked by the upper locking portion, and allows the other end of the ceiling board to slide up, When the other end rises to the height of the end placement portion, the ceiling board auxiliary support swings back, and the other end of the ceiling board can be placed on the end placement portion.

  The above-described slide ascending in contact with the slide guide at the other end of the ceiling board is configured so that the inner angle formed by the slide guide and the end mounting portion immediately above it is configured as an acute angle. Since the end can be brought into contact with the front surface of the slide guide portion from the beginning of the pulling up, it is possible to carry out very smoothly.

  In addition, when using that which constituted the receiving part at the lower end of the slide guide part of the ceiling board auxiliary support tool, place one end of the ceiling board on the auxiliary support plate part of the ceiling board temporary fixing tool, and then temporarily The other end can be placed on the receiving portion, and then the other end can be lifted by sliding the slide guide portion and placed on the end placement portion. Or, conversely, place the other end of the ceiling board on the receiving part first, stabilize the other end side, and then place one end side on the auxiliary support plate part of the ceiling board temporary fixing tool, and then It is also possible to take a procedure in which the other end mounted on the receiving portion is lifted by sliding the slide guide portion and placed on the end portion mounting portion.

  After this, as described above, the ceiling board that is supported by being placed on the auxiliary support plate portion of the ceiling board temporary fixing device and the end placement portion of the ceiling board auxiliary support device is screwed using, for example, an electric screwdriver. Secure to the screwed edge. In the above state, since the ceiling board is slightly separated from the field edge, the operator may push it up slightly and screw it. Therefore, the force required for the operator's work is reduced, and the work can be performed easily, accurately and speedily. Needless to say, the screwing is performed on a portion overlapping the edge of the ceiling board.

  After fixing the above-mentioned screws, leaving a part of the ceiling board in the vicinity of the end opposite to the wall surface, or at another appropriate stage, a new ceiling board temporary fixing tool, The ceiling board is temporarily fixed to the end of the ceiling board opposite to the wall surface. 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.

  Furthermore, before and after this, remove the ceiling board auxiliary support that was locked to the crosspiece, etc., and the distance from the end of the ceiling board that was installed immediately before is one distance from the ceiling board that will be installed. It will be locked to a horizontal member such as another cross using the locking portion. Naturally, at this time, the ceiling board auxiliary support is set so that the front end of the end placement portion faces the wall surface side.

  In the next ceiling board installation work, the operator lifts a new ceiling board and supports one end of the ceiling board on a ceiling board temporary fixture that is temporarily fixed to the end opposite to the wall of the ceiling board that was previously installed. Let 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. Next, the other end of the ceiling board is pulled up in the same manner as described above and placed on the end placement portion of the ceiling board auxiliary support. Similarly, the slide guide portion can be slid up and easily placed on the end placement portion.

  The above-described slide ascending in contact with the slide guide at the other end of the ceiling board is configured so that the inner angle formed by the slide guide and the end mounting portion immediately above it is configured as an acute angle. As described above, the end can be brought into contact with the front surface of the slide guide portion from the beginning of the lifting and can be performed very smoothly.

  In this case as well, if a ceiling board auxiliary support is used that has a receiving part at the lower end of its slide guide part, the ceiling board is fixed to the ceiling board part from the inclined board part of the ceiling board temporary fixing tool. Place one end of the board, and then temporarily place the other end on the receiving part, then slide the slide guide part to raise the other end, and then put it on the end part placing part. be able to. Or, conversely, after placing the other end of the ceiling board first on the receiving portion and stabilizing the other end side, after that, one end side from the introduction inclined plate portion of the ceiling board temporary fixing tool to a part of the substrate portion It is also possible to take a procedure in which the other end mounted on the receiving part is further lifted on the slide guide part and placed on the end part mounting part.

  After this, as described above, the ceiling board that is supported on the part of the board part and the end part mounting part of the ceiling board auxiliary supporter from the introduction inclined plate part of the ceiling board temporary fixing tool, for example, electric Screw in the screw with a screwdriver and fix it to the edge. In the above state, since the ceiling board is slightly separated from the field edge, the operator may push it up slightly and screw it. Therefore, the force required for the operator's work is reduced, and the work can be performed easily, accurately and speedily.

  After fixing the above-mentioned screws, leaving a part of the ceiling board in the vicinity of the end opposite to the wall surface, or at another appropriate stage, a new ceiling board temporary fixing tool, The ceiling board is temporarily fixed to the end of the ceiling board opposite to the wall surface. 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. Also, before and after this, the ceiling board auxiliary supporter is attached to a horizontal member such as a crosspiece at a distance of one ceiling board from the end of the ceiling board temporarily fixed to the ceiling board temporary fixing tool. It will be locked using a locking part. Of course, at this time, the ceiling board auxiliary support tool is set so that the front end of the end placement portion faces the ceiling board side fixed immediately before.

  Thereafter, the ceiling board can be fixed to all necessary areas of the ceiling sequentially by repeating the same work cycle.
