[Action]

 The ceiling plate is pushed up onto the horizontal member that is bridged between the support shaft member that is fixed to the wall that surrounds the ceiling and the support shaft member that is fixed to the ceiling base provided on the ceiling of the building. Since the elastic presser member is supported, it is not necessary for a craftsman to press the ceiling plate by using this ceiling plate retainer when attaching the ceiling plate to the lower surface of the ceiling base during construction of the ceiling. The horizontal member is supported so as to be rotatable about the support shaft member as an axis, and is supported by the support member so that the angle can be adjusted with respect to the wall. With the base end of the horizontal member supported, if the fixing point of the support member is appropriately changed so that the support member makes one round along the wall, and the horizontal member is swiveled, it will be attached to the ceiling base. It becomes possible to hold down all the ceiling boards that should be in sequence.

Since the horizontal member is expandable and contractible, if the horizontal member is used, the horizontal member is hung between the support member and the support member regardless of the length of the length. Not only is it possible to bridge the members, but also when not in use, the ceiling plate retainer can be made compact by contracting the lateral members.

The pressing member has an upper end portion that is lifted to press the ceiling plate against the ceiling base material, and an upper end portion is moved downward between the upper end portion and the ceiling base material. The ceiling plate is convertible into a lowered state in which an insertion allowance is formed so that the ceiling plate can be inserted from the lateral direction, and at the bottom of the pressing member, there is provided return means for returning the pressing member to the lowered state. Therefore, by using this pressing member, it is possible to easily insert the ceiling plate between the ceiling substrate and the ceiling plate retainer after the ceiling plate retainer is bridged between the ceiling substrate and the wall. Become.

Since the holding member is detachably attached to the horizontal member, not only can the holding member be attached to any position of the horizontal member, but the holding member can be removed when not in use. This makes the ceiling board retainer compact.

Since the screw fastening portion provided on the upper end portion of the support shaft member is screwed into the ceiling base by the operation handle detachably attached to the lower end portion of the support shaft member, By using this support shaft member, the support shaft member can be easily attached to the ceiling substrate.

An example of how to use the ceiling board retainer 100 configured as described above will be described below. First, as shown in FIG. 2, a procedure for bridging the ceiling board retainer 100 to the ceiling base 210 and the wall 300 will be described. The support shaft member 1 is fixed to the ceiling base 210. This is done by attaching the operation handle 15 to the lower end of the support shaft body 10 of the support shaft member 1, supporting the support shaft body 10 with one hand, and rotating the operation handle 15 with the other hand. As shown in FIG. 2 or FIG. 11, the support shaft member 1 is attached to the ceiling 200 at a substantially central portion thereof and to a corner portion of a ceiling plate to be attached, for example, a corner portion of the ceiling plate 221. Is preferred. As shown in FIG. 5, pay attention so that the spindle body 10 extends vertically downward and the screw fastening portion 13 is screwed to the root (lower end). When the work of fixing the support shaft member 1 is completed, the operation handle 15 is removed from the support shaft body 10. The support member 2 is fixed to the wall 300 with the screw member 28. The position where the support member 2 is attached is not particularly limited, but it is preferably a position where a large number of ceiling plates 220 (221, ...) Can be pressed at one time. Here, as shown in FIG. 2 or FIG. 11, the two ceiling plates 220 and 221 are set at positions where they can be pressed. As shown in FIG. 6, be careful to abut the support member 2 on the ceiling rim 230. If the ceiling rim 230 is not attached, the ceiling rim 230 is abutted against the ceiling base 210. As shown in FIG. 2, a horizontal member 3 is bridged between the support shaft member 1 and the support member 2. This is because the receiving portion 33 of the horizontal member 3 is loosely fitted to the spindle body 10 from below, the screw member 18 is screwed, and the horizontal member 3 is slightly lifted to move the spindle body 37 of the spindle portion 36. This is performed by loosely inserting it into the receiving portion 23 of the support member 2. At this time, the horizontal member 3 which has been contracted in advance is extended. An appropriate number of pressing members 4, for example, two as shown in FIG. 2, are attached to the horizontal member 3. As shown in FIG. 8, after inserting the crimping plate 47 of the mounting portion 45 into the channel material 30 (31) from the opening 30f (31f) of the channel material 30 (31) in a lying state, the mounting portion 45 Putting a finger on the rotary operation part 48, the rotary operation part 48 is rotated so as to erect the crimping plate 47 as shown in FIG. Here, the crimping plate 47 is rotated clockwise. In this state, the pressure contact plate 52 is in a lowered state, and an allowance 5 for inserting the ceiling plates 220 and 221 can be provided between the pressure contact plate 52 and the ceiling lower portion 210. When the ceiling plate retainer 100 is ready as described above, the ceiling plate 220 is inserted from the insertion allowance 5 while keeping the ceiling plate 220 in a substantially horizontal state. Simultaneously with the insertion, the upper half of the handle 40 is erected, the press plate 52 is pressed against the ceiling plate 220, and the holding part 60 is hooked on the lip part 30e (31e). The same applies to the ceiling plate 221. The state thus far is shown in FIGS. 2 and 11. The ceiling plates 220 and 221 are fastened to the ceiling base 210 with nails 240 or the like. Next, as shown in FIG. 3, a procedure for bridging the ceiling board retainer 100 to the ceiling base 210 and the wall 301 will be described. The horizontal member 3 is slightly lifted to remove the support shaft body 37 of the support shaft portion 36 from the receiving portion 23 of the support member 2 and remove the support member 2 from the wall 300. The support member 2 is fixed to the wall 301, and the ceiling boards 222 and 223 are fastened to the ceiling base 210 according to the same procedure as the ceiling boards 220 and 221. The state thus far is shown in FIGS. 3 and 12. Hereinafter, as shown in FIGS. 13 to 16, the ceiling plates 224 to 229 can be attached by changing the attachment position of the support member 2. It is also possible to prepare a plurality of support members 2 and attach them to the wall surrounding the ceiling 200 at appropriate intervals beforehand. After the installation of all the ceiling boards 220 to 229 is completed, the support member 1 is removed using the operation handle 15. In the case of the above example, it goes without saying that the corners of the ceiling plates 221, 222, 227, 228 are cut out in advance in order to allow the support shaft member 1 to escape. The notched portion and the hole of the screw member 28 used for fixing the support member 2 may be filled with putty before finishing.

According to the above-described embodiment, the holding member 4 for pushing up the ceiling plate 220 (221, ...) Is supported by the horizontal member 3 that is bridged between the support shaft member 1 and the support member 2, and the holding member 4 is pushed. Since the pressure contact plate 52 of the member 4 is kept in pressure contact with the ceiling plate 220 (221, ...), when the ceiling 200 is constructed, the ceiling plate 220 ( (221, ...) If the ceiling plate retainer 100 is used when attaching the ceiling plates 220 (221, ...), it is not necessary for the craftsman to hold down the ceiling plate 220 (221, ...) By himself, one craftsman can easily attach the ceiling plate 220 (to the ceiling substrate 220). 221, ...) can be attached, and workability and work efficiency are dramatically improved. The horizontal member 3 is swung with the support shaft member 1 as an axis by the support portion 33 loosely fitted to the support shaft body 10 of the support shaft member 1 and the support shaft body 37 loosely inserted in the support portion 23 of the support member 2. Since it is supported so that it can be obtained and the angle is freely adjustable with respect to the wall, all the ceiling plates 220 to 229 to be attached can be sequentially pressed by turning the horizontal member 3, Excellent workability is expected. Since the horizontal member 3 is expanded and contracted by the combination of the two channel members 30, 31, etc., regardless of whether the length between the support shaft member 1 and the support member 2 is short or long, Since the horizontal member 3 can be bridged between them, positioning of the mounting position of the ceiling board retainer 100 is unnecessary, and not only is excellent workability expected, but the horizontal member 3 can be contracted. Since it can be carried, the ceiling board retainer 100 can be easily carried. By the weight 55, the pressing member 4 is returned to and kept in the lowered state unless an external force is applied, and the displacement of the connecting portion 53 and the stopper 41 cause the pressing plate 52 to be substantially horizontal. Since it is kept in a state, even one craftsman can put the ceiling plate 220 (221, ...) On the insertion allowance 5 after the ceiling plate retainer 100 is laid between the ceiling substrate 210 and the wall. It can be easily inserted to convert the pressing member 4 to the raised state, and excellent construction efficiency is expected. Since the presser member 4 is detachably attached to the horizontal member 3 via the attachment portion 45, the presser member 4 can be attached to any position of the horizontal member 3, so that the presser ceiling can be attached. Not only can the mounting position of the pressing member 4 be adjusted according to the position of the plates 220 (221, ...), but also the pressing member 4 can be removed and transported, so that the ceiling plate retainer 100 can be easily transported. Become. Since the screw fastening portion 13 of the support shaft member 1 is screwed into the ceiling base 210 by the operation handle 15 which is detachably attached to the support shaft member 1, the support shaft member 1 is attached to the ceiling base 210. It can be easily fixed.

The ceiling plate retainer 100 is not limited to the one in the above-described embodiment, but the ceiling plate retainer 100 is laterally provided between the ceiling base 210 and the support shaft member 1 and the support member 2 fixed to the wall 300 (301), respectively. In particular, if the frame member 3 is bridged, the pressing member 4 is supported by the horizontal member 3, and the ceiling plate 220 (221, ...) Is pressed against the ceiling base 210 by the pressing member 4, The configuration does not matter.

Further, in the above embodiment, the returning means is constituted by the weight portion 55, but the present invention is not limited to this. For example, a spring is provided between the handle 40 and the mounting portion 45. If the pressure contact portion 50 is returned to the lowered state by being inserted, and the handle portion 40 is rotated and returned by the spring so that the pressure contact portion 50 is in the lowered state, no matter what the configuration is, Good.

Further, in the above-described embodiment, the pressure contact portion 50 can be converted into the raised state and the lowered state by the rotation of the handle portion 40, but the invention is not limited to this. A spring that urges the pressure contact portion 50 to rise is interposed between the pressure contact portion 50 and a locking mechanism that holds the pressure contact portion 50 in the lowered state. As long as it is converted into the ascending state and the descending state and is held in the descending state, it does not matter in which the vertical movement can be performed.

Furthermore, in the above embodiment, the holding member 4 is detachably attached to the side portion of the horizontal member 3, but it can be slid on the horizontal member 3 along its longitudinal direction. May be attached to.

In the above embodiment, the case where the ceiling board 220 (221, ...) Such as a plaster board is attached to the lower side surface 210a of the ceiling base 210 made of a ceiling margin or the like has been described. The ceiling board retainer 100 can also be used when a decorative ceiling finishing board is attached to the lower surface of a gypsum board or the like.

[Effect of the device]

 According to the ceiling board retainer according to the present invention, the ceiling plate retainer is mounted on the ceiling base of a building, and the upper end of the support shaft member is fixed between the supporting member and the supporting member fixed to the wall surrounding the ceiling. Since the pressing member that pushes up the ceiling plate is supported by the horizontal member that is passed over, if this ceiling plate holder is used when installing the ceiling plate on the lower surface of the ceiling base during construction of the ceiling, the craftsman himself will be able to use the ceiling plate. Since it is not necessary to hold down, it is possible for one craftsman to easily attach the ceiling plate to the lower part of the ceiling, which dramatically improves workability and work efficiency. The horizontal member is supported so as to be rotatable about the support shaft member as an axis, and is supported by the support member so that the angle can be adjusted with respect to the wall. With the base end of the horizontal member supported, if the fixing point of the support member is appropriately changed so that the support member makes one round along the wall, and the horizontal member is swiveled, it will be attached to the ceiling base. Excellent workability is expected because all the ceiling plates that should be used can be pressed in sequence.

Since the horizontal member is stretchable, if this horizontal member is used, regardless of the length between the support member and the support member, the horizontal member is stretched between them. Since the members can be bridged, it is not necessary to position the ceiling plate retainer at the mounting position, so not only is excellent workability expected, but the horizontal members can be contracted for transportation. The ceiling board retainer can be easily transported.

Between the upper end of the pressing member is lifted to press the ceiling plate against the ceiling base, and when the upper end is moved down between the upper end and the ceiling base. The ceiling plate is convertible into a lowered state in which an insertion allowance is formed so that the ceiling plate can be inserted from the lateral direction, and at the bottom of the pressing member, there is provided return means for returning the pressing member to the lowered state. Therefore, even if only one craftsman uses this pressing member, the ceiling plate can be easily inserted between the ceiling substrate and the ceiling plate retainer after the ceiling plate retainer is laid between the ceiling substrate and the wall. The pressing member can be converted to the raised state, and excellent construction efficiency is expected.

Since the pressing member is detachably attached to the horizontal member, the pressing member can be attached to any position of the horizontal member, so that the pressing member can be attached to the position of the ceiling plate to be pressed. Not only can the mounting position of the presser member be adjusted, but the presser member can be removed for transportation, so that the ceiling plate retainer can be easily transported.

Since the screw fastening portion provided on the upper end portion of the support shaft member is screwed into the ceiling base by the operation handle detachably attached to the lower end portion of the support shaft member, By using this support shaft member, the support shaft member can be easily attached to the ceiling base.
