Description

The present invention relates to a building ceiling and a construction method thereof.

In the construction of the ceiling of a building, the ceiling surface material is attached to the ceiling base material such as the field edge by fixing means (screws, screws, etc.) using a special tool in the upward work. Installation of this ceiling surface material requires experience and skill, and it is not a task that anyone can do. Nowadays, labor shortages are being criticized and labor saving technology is eagerly desired, and the development of technology that allows anyone to easily construct a building ceiling has become an issue.

On the other hand, ceiling surface materials such as gypsum board are generally constructed by abutting, but there is a problem that the gaps are conspicuous when a gap is generated between adjacent ceiling surface materials in the abutting construction. In order to eliminate the occurrence of gaps, measures such as interposing a joint material between the ceiling surface materials are taken, but the construction of the joint material also requires experience and technology as described above, and the construction period is lengthened and the materials are used. New challenges such as increased costs arise.

Here, a suspended ceiling construction method has been proposed that achieves labor saving, eliminates the generation of waste materials, and provides a base material with a simple and clean finish. Specifically, a suspended ceiling base material is constructed of a base material piece that is bonded to the field edge and the ceiling material mounting surface of the field edge in a size that secures at least a ceiling material mounting allowance, and this suspended ceiling. This is a method in which the base material is arranged on the suspension member at appropriate intervals to form a base frame for laying the ceiling material, and then the ceiling material is attached to one side of the adjacent base base material (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 8-27942

Since the ceiling constructed by the suspended ceiling construction method described in Patent Document 1 is constructed by abutting adjacent ceiling materials, the above-mentioned problem, that is, a problem that a gap is likely to occur between ceiling surface materials is solved. It cannot be resolved.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a building ceiling in which there is no gap between adjacent ceiling surface materials and a method for constructing a building ceiling in which anyone can easily construct the building ceiling. It is supposed to be.

In order to achieve the above object, one aspect of the building ceiling construction method according to the present invention is
A plurality of field edges extending in the second direction have a width extending over the plurality of field edges with respect to the ceiling base arranged at intervals in the first direction, and are rectangular in a plan view. It is a construction method of the building ceiling to which the ceiling surface material of
The ceiling surface material includes a pair of facing first end sides extending in the first direction and a pair of facing second end sides extending in the second direction, and the pair of first ends. One of the one end sides is provided with at least one notch, and the other end side is provided with at least one hole in the vicinity of the first end side.
A first row of leading ceiling surface materials is constructed by arranging the plurality of ceiling surface materials in the second direction and fixing them to the field edge while overlapping the ends of the plurality of ceiling surface materials. Process and
It has a step B of constructing the trailing ceiling lumber group in the second and subsequent rows on the side of the preceding ceiling lumber group.
In the A step and the B step,
In both the leading ceiling surface material group and the trailing ceiling surface material group, the first ceiling surface material first attached to the field edge is fixed to the field edge by fixing means through the notch and the hole. death,
The second and subsequent ceiling surface materials attached to the field edge are the first ceiling surface material or the first ceiling surface material in which the notch provided in the second ceiling surface material is previously fixed to the field edge. It is characterized in that it is inserted into the fixing means above the second ceiling surface material and fixed to the field edge by another fixing means through the hole provided in the second ceiling surface material.

According to this aspect, the pair of first end sides of the ceiling surface material having a rectangular shape in a plan view are provided with notches and holes, respectively, and the first ceiling surface material to be first attached to the field edge is provided through the notches and holes. The second ceiling surface material that is fixed to the field edge by fixing means and attached to the field edge after the second is the first ceiling surface material or the second ceiling that is fixed to the field edge in advance of the notch. After inserting it into the fixing means above the face material, it is fixed to the field edge by another fixing means through the hole provided in the second ceiling face material, and the leading ceiling face material group in the first row and the second and subsequent rows. A group of trailing ceiling surface materials will be constructed. By this construction method, in the place where two ceiling surface materials are overlapped by the fixing means and fixed to the field edge, one of the ceiling surface materials fixed in advance is located below by its own weight. The other ceiling surface material, which is supported by being depressed to the fixing means side and is inserted in the post-construction, is similarly depressed by its own weight and is superposed on the one ceiling surface material. Therefore, it is possible to construct the building ceiling while superimposing the ends of the adjacent ceiling surface materials without gaps by a simple construction method.

Here, the building ceiling to be constructed is composed of a first row of leading ceiling surface materials and one or both of the left and right trailing ceiling surface materials (that is, two or three rows of ceiling surfaces). A form composed of a group of leading ceiling surface materials in the first row and two or more rows of trailing ceiling surface materials on either or both of the left and right sides (that is, three or more rows of ceiling surfaces). It is composed of a group of materials).

Further, as the fixing means, a form consisting of a male snap button and a female snap button fitted to the male snap button, a male snap button, a relay snap button fitted to the male snap button, and a relay are used. A form consisting of a female snap button fitted to a snap button, a form consisting of a rivet hole and a rivet, a form consisting of a screw hole and a screw, a hanging piece, and an overhang piece protruding laterally at the lower end of the hanging piece. , The ceiling surface material is inserted and attached on the overhanging piece, and there is a form consisting of the insertion material.

Further, the ceiling surface material attachment may be slidably attached to the field edge, and various types of fixing means described above may be attached below the ceiling surface material attachment. This ceiling surface material attachment has a substantially U-shape with a cross-sectional shape that opens upward, has a through hole in the bottom piece, and is slidably locked to the ceiling base material. The loose fitting body has a mounting material provided with a loose fitting body that is loosely fitted into the through hole from above the bottom piece and a mounting piece that is above the free fitting body and is mounted on the upper surface of the bottom piece. A fixing means is provided on the bottom surface to which the ceiling surface material is attached.

Here, in this ceiling lumber attachment, it is preferable to set the cross-sectional dimension of the idle fit body to be smaller than the cross-sectional dimension of the through hole. Since the loose fitting body of the mounting material is loosely fitted to the through hole in the bottom piece of the locking material with play, for example, the field edge is installed with a construction error. Even in this case, by sliding the mounting material with respect to the locking material within the play range, the ceiling surface material can be easily attached to the fixing means of the mounting material. For example, once the field edge is assembled, if the field edge is attached in a manner having a construction error, in order to attach the ceiling surface material to the field edge having this construction error, After performing the construction to change the mounting position of the field edge, it is necessary to reattach the ceiling surface material to the field edge, which requires time and effort for adjustment. However, since the cross-sectional dimension of the idle fit is set smaller than the cross-sectional dimension of the through hole, the mounting position of the field edge is often set with respect to the field edge that can be installed with a construction error. The ceiling surface material can be easily attached to the fixing means without modification.

Further, in the ceiling surface material mounting tool, a counterbore groove is provided on the upper surface of the bottom piece, a through hole is provided in the center of the counterbore groove, and among the mounting materials, the mounting piece is housed in the counterbore groove. It is more preferable that the loose fitting body is configured to loosely fit into the through hole. According to this form, the mounting piece of the mounting material is accommodated in the counterbore groove, so that the area around the counterbore groove on the upper surface of the bottom piece of the locking material is brought into contact with the bottom surface of the ceiling base material. Therefore, the ceiling surface material fixture can be stably fixed to the field edge.

Further, the ceiling surface material attached to the field edge via the ceiling surface material attachment is formed of, for example, a lightweight and thin plate material.

In addition, another aspect of the construction method of the building ceiling according to the present invention is as follows.

Even with this construction method, in the place where two ceiling surface materials are overlapped by the fixing means and fixed to the field edge, one of the ceiling surface materials fixed in advance is positioned below by its own weight. The other ceiling surface material, which is supported by being depressed to the fixing means side, is similarly depressed by its own weight and is superposed on the one ceiling surface material. Therefore, it is possible to construct the building ceiling while superimposing the ends of the adjacent ceiling surface materials without gaps by a simple construction method.

Further, in the construction method of this embodiment, since the ceiling surface material has only a notch, the manufacturability of the ceiling surface material is improved.

Further, in another aspect of the construction method of the building ceiling according to the present invention,

It is characterized in that the sides are overlapped with each other, the corresponding notches are aligned to form a communication notch, and the notches are fixed to the field edge by the fixing means via the communication notches.

According to this aspect, the ceiling surface material having a rectangular shape in a plan view is provided with notches at the center of a pair of first end sides, the center of a pair of second end sides, and four corners in total. The ceiling surface material is fixed to a total of three field edges, two field edges along the pair of second end edges and one field edge passing through the center of the pair of first end edges, and adjacent ceiling surfaces.

A total of three places in the center of the second end side of the above can be fixed by a common fixing means. If the first end side of the ceiling surface material provided by the adjacent ceiling surface material group is not shifted, the corners of the four ceiling surface materials, that is, the four locations will be fixed by a common fixing means, and the four sheets will be fixed. The thickness of the fixed portion becomes thicker due to the overlapping of the ceiling surface materials, but since the three ceiling surface materials need only be overlapped as in this embodiment, it is possible to eliminate the thickness of the fixed portion becoming too thick.

Moreover, one aspect of the building ceiling according to the present invention is
A plurality of field edges extending in the second direction have a width extending over the plurality of field edges with respect to the ceiling base arranged at intervals in the first direction, and are rectangular in a plan view. It is a building ceiling to which the ceiling surface material of

The field edge 31 extending in the second direction is arranged and supported in the first direction at a predetermined interval with respect to the field edge receiver 32. In FIG. 7, five field edges 31A to 31E are illustrated. Here, the field edge receiver 32 and the field edge 31 are formed by metal fittings having a U-shaped cross section. Further, the field edge 31 is supported by a screw, a clip, or the like with respect to the field edge receiver 32. In FIG. 7, the upper part of the ceiling base material 30 is the ceiling space side, and the lower part of the ceiling base material 30 is the indoor space side.

After the ceiling base material 30 is installed as shown in FIG. 7, the upper portions of the two hanging pieces 11 of the locking material 10A are opened sideways to widen the upper opening, and the inside of the locking material 10A is opened through the openings. By passing the field edge 31 and returning the hanging piece 11 opened to the side, the two locking claws 13 are locked to the left and right upper ends of the field edge 31, and the locking material 10A is attached to the field edge 31. It can be slidably attached in the Y1 direction. At this time, the counterbore groove 16 and the through hole 15 provided in the bottom piece 12 of the locking material 10A are loosely fitted with the mounting piece 17 and the loose fitting body 18 of the mounting material 10B, respectively, with play. Only the male snap button 22 forming the fixing means 21 is fixed to the bottom surface of the loose fitting body 18, and the female snap button 23 is removed. In addition to the method of attaching the locking material 10A to the field edge 31 after constructing the ceiling base material 30, the ceiling base material 10A is attached to the field edge 31 in advance with a predetermined number of locking materials 10A. 30 may be constructed.

In FIG. 7, the locking material 10A and the mounting material 10B are attached to the three adjacent field edges 31 at positions corresponding to the fixing points of the ceiling surface material to be attached. As an example, in the field edges 31A to 31C, the region A1 indicated by the alternate long and short dash line is the region corresponding to the ceiling surface material to be first attached, and at the eight fixing points of the ceiling surface material, eight sets of locking members 10A and eight sets of locking members 10A and The mounting material 10B is arranged. Further, in the construction method of the building ceiling according to the embodiment, since the ends of the adjacent ceiling surface materials are overlapped with each other and fixed by the common fixing means 21, as shown in the figure, the area A1 indicated by the alternate long and short dash line is used. Area A2 wraps. In the field edges 31A to 31C, a row of ceiling surface materials is formed by superimposing ceiling surface materials (not shown) on the field edges 31A to 31C according to the dimensions of the ceiling. do.

Then, while sharing the field edges 31C, ceiling surface materials are attached to the regions A3 and A4 indicated by the alternate long and short dash lines also in the field edges 31C to 31E to form a separate row of ceiling surface materials.

As is clear from FIG. 7, the row-shaped ceiling surface material group is formed by overlapping a plurality of ceiling surface materials, which are its constituent elements, with each other, and is formed in a separate row-like shape adjacent to each other. Similarly, in the ceiling surface material group, a plurality of ceiling surface materials are formed by superimposing their ends on each other. Further, the adjacent rows of ceiling surface materials also have their ends overlapped with each other to form a building ceiling.

Next, the ceiling surface material attached to the field edge 31 via the ceiling surface material attachment 20 will be described. First, the ceiling surface material 40 shown in FIG. 8A has a rectangular shape in a plan view having a pair of first end sides 41 and 42 and a pair of second end sides 43 and 44, and is formed of a lightweight and thin plate material. ing. Specifically, an ultra-lightweight ceiling material manufactured by Nohara Holdings, Inc .: CARLTON, an ultra-lightweight ceiling material manufactured by ABC Trading Co., Ltd .: Karuten, and the like can be applied. Here, the "thin thickness" means, for example, a thickness in the range of 1 mm to several mm.

The ceiling surface material 40 is provided with a notch 48 at the center position of one first end side 41, each center position of a pair of second end sides 43, 44 with the other first end side 42, and four corners. The portion 45 is provided with a total of seven holes 49.

When the building ceiling is constructed using the ceiling surface material 40 shown in FIG. 8A, for example, in the area A1 (see FIG. 7), the male snap button 22 located above the central field edge 31B is female. The snap button 23 is fitted to form the fixing means 21. Next, the notch 48 is inserted into the gap G (see FIG. 6) of the fixing means 21, and the seven holes 49 are passed through the corresponding male snap buttons 22 in the region A1. Finally, by fitting the female snap button 23 to the male snap button 22 located below the field edge 31B to form the fixing means 21, the ceiling surface material 40 in the area A1 is formed by the two fixing means 21. Can be fixed. After that, in the area A2 (see FIG. 7), the end portion of the separate ceiling surface material 40 can be overlapped with the end portion of the ceiling surface material 40 in the area A1 and fixed in the area A2 in the same manner.

On the other hand, the ceiling surface material 40A shown in FIG. 8B has basically the same configuration as the ceiling surface material 40, but does not have holes 49 and has notches 48 and 48A at all eight locations. It differs from the ceiling surface material 40 in that it is present.

The notches 48 at the center positions of the first end sides 41 and 42 and the second end sides 43 and 44 have a half-track-like planar shape, but the notches 48A at the corners 45 are 1/4. It has a circular planar shape. As shown in FIG. 7, since the ceiling surface material 40 is attached to the three field edges 31, the ceiling surface material 40 is provided with two holes 49 and one notch 48 on the first end sides 41 and 42. When the ceiling surface material 40 is attached to, for example, four field edges 31, the ceiling surface material has two holes 49 and two notches 48 on the first end sides 41 and 42, and the ceiling surface material 40 is attached. The number of holes 49 and the number of notches 48 are set according to the number of 31. This also applies to the ceiling surface material 40A, and when the ceiling surface material 40A is attached to, for example, four field edges 31, two notches 48 and 48A are provided on the first end sides 41 and 42. It becomes the ceiling surface material. Further, the ceiling surface material 40 has three holes 49 on the second end sides 43 and 44, and the ceiling surface material 40A has two notches 48A and one notch 48 on the second end sides 43 and 44. However, when the length of the ceiling surface materials 40, 40A in the second direction becomes long, the ceiling surface materials 40, 40A attached to the field edge 31 are spaced so as not to bend, and four or more holes 49 or , It is preferable to have two notches 48A and two or more notches 48. In the following description, the construction method of the building ceiling when the ceiling surface material 40A is applied will be described.

As shown in FIG. 9, the fixing means 21 is formed by fitting the female snap button 23 in the Y2 direction to the male snap button 22 located above the region A1 in the field edge 31B.

Next, as shown in FIG. 10, the ceiling surface material 40A (first ceiling surface material 40Aa) is inserted in the gap G of the fixing means 21 in the Y3 direction by inserting the notch 48 in the center of the first end side 41 into the gap G. Slide to. At this time, by appropriately deforming the first ceiling surface material 40Aa, the other notches 48 and 48A are fitted into the corresponding male snap buttons 22 to expose each male portion 22a downward. Although not shown here, an operator holds the first ceiling surface material 40Aa from below toward the field edge 31 side.

In the construction of the ceiling base material 30 shown in FIG. 7, for example, when there is a construction error when mounting the field edge 31, as shown in FIG. 10, with respect to the male snap button 22 provided in each mounting material 10B. When trying to insert the notch 48,48A of the first ceiling surface material 40Aa, the notch 48,48A cannot be inserted into the male snap button 22 due to the construction error of the field edge 31. Can occur.

However, in the illustrated construction method, the mounting material 10B is attached to the locking material 10A with play, and as shown in FIG. 10, the mounting material 10B is slidable in the Z direction, which is the 360-degree direction. As a result, the mounting member 10B can be slid within the range of this play, and the notches 48 and 48A can be inserted through the male snap button 22.

Next, as shown in FIG. 11, by fitting the female snap button 23 in the Y4 direction to the male snap button 22 into which the notch 48 in the center of the first end side 42 is inserted, the fixing means 21 is formed, and the first ceiling surface material 40Aa is fixed by two fixing means 21. In this fixed state, the male portion 22a of the male snap button 22 into which the other notches 48 and 48A are inserted is in a state of being exposed downward.

Next, as shown in FIG. 12, the second ceiling surface material 40Ab is placed in the center of the first end side 41 with respect to the gap G of the lower fixing means 21 fixing the first ceiling surface material 40Aa. Slide it in the Y5 direction by inserting a certain notch 48. At this time, in the gap G, the first ceiling surface material 40Aa fixed in advance falls to the female snap button 23 side located below due to its own weight and is supported, and is inserted in the post-construction. (Ii) The ceiling surface material 40Ab is similarly depressed by its own weight and is superposed on the first ceiling surface material 40Aa. In FIG. 12, the first end side 41 of the second ceiling surface material 40Ab inserted in the post-construction is shown by a alternate long and short dash line.

Even in the second ceiling surface material 40Ab inserted in the post-construction, by appropriately deforming the other notches 48 and 48A, the other notches 48 and 48A are fitted into the corresponding male snap buttons 22 to expose each male portion 22a downward. ..

Then, as shown in FIG. 13, the female snap button 23 is attached to the male snap button 22 into which the notch 48 in the center of the first end side 42 of the second ceiling surface material 40Ab that has been post-constructed is inserted. By fitting in the direction, the fixing means 21 is formed, and the second ceiling surface material 40Ab is fixed by the two fixing means 21.

In this way, in the three field edges 31A to 31C, the plurality of ceiling surface materials 40A are sequentially fixed while wrapping their ends with each other, whereby the leading ceiling surface material group 50A in the first row is formed. Install (step A). Although only two ceiling surface materials 40A are shown in FIG. 13, a plurality of ceiling surface materials 40A are attached to both ends of the field edges 31A to 31C in the second direction, and the preceding ceiling surface materials are attached. Group 50A is formed.

Next, as shown in FIG. 14, in the three adjacent field edges 31C to 31E, a plurality of ceiling surface members 40A are sequentially fixed while wrapping their ends with each other by the same method. As a result, the trailing ceiling surface material group 50B in the second row is constructed. Then, the trailing ceiling surface material group in the third and subsequent rows is also constructed by the same method. In FIG. 14, only one row of trailing ceiling lumber group 50B is shown on the right side of the leading ceiling lumber group 50A, but a plurality of rows of trailing ceiling lumber group 50B may be installed. Further, a single row or a plurality of rows of trailing ceiling lumber group 50B may be installed on the left side of the leading ceiling lumber group 50A (the above is step B).

Here, the trailing ceiling surface material group 50B is constructed so as to be offset by half the length of the ceiling surface material 40A in the second direction with respect to the preceding ceiling surface material group 50A. By shifting the trailing ceiling surface material group 50B in this way, the trailing ceiling surface material group 50B is provided to the overlapping portion of the two ceiling surface materials 40A constituting the leading ceiling surface material group 50A. It is only necessary to superimpose only one ceiling surface material 40A to be formed, and three ceiling surface materials 40A are overlapped in the gap G at the rating point P.

If the first end side 41 of each ceiling surface material 40A provided by the adjacent leading ceiling surface material group 50A and the trailing ceiling surface material group 50B is not shifted, the corners of the four ceiling surface materials 40A, that is, four locations Will be inserted into the gap G of the common fixing means 21. By overlapping the four ceiling surface materials 40A in this way, the thickness of the fixed portion becomes thick, and there is a risk that the four ceiling surface materials 40A cannot be inserted into the gap G, and the four ceiling surface materials 40A Overlapping may result in poor appearance. As shown in the illustrated example, these problems are solved by constructing the first end side 41 of each ceiling surface material 40A provided by the leading ceiling surface material group 50A and the trailing ceiling surface material group 50B so as to be displaced from each other. However, the first end side 41 of each ceiling surface material 40A provided in the leading ceiling surface material group 50A and the trailing ceiling surface material group 50B may be constructed without shifting as shown in the illustrated example.

Next, as shown in FIG. 15, the female snap button 23 is fitted to the male snap button 22 at the rating point P in the Y7 direction to form the fixing means 21, and the leading ceiling surface material group 50A and the trailing ceiling are formed. The building ceiling 60 is constructed by fixing the overlapping portion of the face material group 50B with the fixing means 21.

As is clear from FIG. 15, in the building ceiling 60, since the edges of the adjacent ceiling surface materials 40A are overlapped with each other, there is no gap between the ceiling surface materials as in the case of butt. In particular, in the place where the two ceiling surface materials 40A are overlapped by the fixing means 21 and fixed to the field edge 31 by the construction method shown in the figure, one of the ceiling surface materials 40A fixed in advance is used. The other ceiling surface material 40A, which is supported by falling down to the female snap button 23 side located below by its own weight and inserted in the post-construction, also falls down by its own weight and overlaps the one ceiling surface material 40A. It will be combined. Therefore, the building ceiling 60 can be constructed by superimposing the ends of the adjacent ceiling surface materials 40A without gaps by a simple construction method.

Further, since the ceiling surface material 40A is formed of a lightweight and thin plate material, the installation of the ceiling surface material 40A can be facilitated, and the influence of the weight of the ceiling surface material 40A on the building frame can be suppressed. ..

Further, since the ceiling surface material 40A is thin, the step at the overlapping portion between the ends of the adjacent ceiling surface materials 40A becomes inconspicuous, and a neat overlapping line can be formed.

Further, since the ceiling surface material 40A is formed of a plate material, the ceiling surface material 40A has a certain degree of rigidity, and therefore, when fastening the overlapping portion of the ceiling surface materials 40A with a snap button, Good fastening performance is guaranteed.

The illustrated building ceiling 60 may be applied to either a temporary building or a main building. Examples of temporary buildings include temporary arenas for outdoor events, temporary housing that requires immediate construction after the earthquake, and temporary accommodation facilities. In addition, examples of the main building include large stores such as commercial facilities and leisure facilities, factories, office buildings (system ceilings), medical / welfare facilities, government offices, hotels and accommodation facilities, educational facilities, and the like.

It should be noted that the configuration and the like described in the above embodiment may be other embodiments in which other components are combined, and the present invention is not limited to the configuration shown here. .. This point can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form thereof.
