The auxiliary roller 10 is attached to the lower part between the adjacent field edge members 6 by using the arrangement member 108. The ceiling surface material 4 drawn out from the roll material 8 is pulled by the auxiliary roller 10 and conveyed first by the auxiliary roller 10, and the conveying direction is guided toward the groove-shaped holding portion 14 of the holding material 12. ..
According to the auxiliary roller 10, the ceiling surface material 4 unwound from the roll material 8 can be held and conveyed, and the direction of the ceiling surface material 4 can be changed to a direction close to horizontal for guidance. Then, the edge portion 5 of the ceiling surface material 4 can be inserted (fitted) into the groove-shaped holding portion 14 by the holding material 12 in this direction. Therefore, the guide function of the auxiliary roller 10 facilitates the laying of the ceiling surface material 4, such as inserting it into the groove-shaped holding portion 14.

The roll material 8 is preferably arranged in the vicinity of the wall edge 78 on one side of the ceiling portion 2 and slightly below the field edge material 6, and is arranged at a position suitable for feeding out the ceiling surface material 4. The ceiling surface material 4 unwound from the roll material 8 needs to be transported to the lower part of the field edge material 6 arranged on the ceiling portion 2 as it is.
If this transport path is long, the weight of the ceiling surface material 4 will be a burden for the transport work, so an appropriate direction and length should be considered in consideration of workability and the like. Here, the angle from the axial center of the arranged roll material 8 toward the axial center of the auxiliary roller 10 is about 45 degrees from the horizontal. Therefore, the ceiling surface material 4 conveyed from the roll material 8 to the auxiliary roller 10 is about 30 to 45 degrees from the horizontal.

Further, the auxiliary roller 10 is arranged near the lower part of the field edge member 6 and at a position that does not interfere with the rotation of the auxiliary roller 10.

In the arrangement of the roll material 8, first, the attachment 84 of the suspension member 82 is locked and attached to the left and right field edge materials 6 at the place where the ceiling surface material 4 is arranged. The fixture 84 has the tip of the engaging piece portion 92 plunged (fitted) into the recess 23 of the field edge member 6, and the recessed portion of the engaging piece portion 92 is hooked on the side plate portion 22 of the field edge material 6. So it's easy to install.

Then, the hanging rod 86 is attached to the substrate portion 90 of each attachment 84 in a hanging state. At this time, the upper end portion of the suspension rod 86 is inserted into the hole provided in the substrate portion 90, and the nut is screwed into the upper end portion of the suspension rod 86 to fix it to the substrate portion 90. Further, by fixing the upper end portion of the hanging rod 86 to the substrate portion 90 in a state of being in contact with the bottom plate portion 20 of the field edge material 6, the attachment 84 and the hanging rod 86 can be firmly attached to the field edge material 6. Become.

Further, the lower portion of the suspension rod 86 is inserted into the holding hole 96 at the end portion of the shaft member 88, the coil spring 100 is interposed between the lower portion of the shaft member 88 and the lower end portion of the suspension rod 86, and the nut 98 is inserted from below. Is screwed in and one end of the shaft member 88 is attached to the suspension rod 86. Then, the prepared roll material 8 (cover members 32 are arranged at both ends) is lifted, the tubular member 30 of the roll material 8 is fitted from the other end of the shaft member 88, and the roll material 8 is held by the shaft member 88. Get ready.

Next, the lower portion of the suspension rod 86 attached to the other attachment 84 is inserted into the holding hole 96 at the other end of the shaft member 88 to which the roll member 8 is attached first, the coil spring 100 is interposed, and the nut 98 is inserted. The other end is attached by screwing to the hanging rod 86.
As a result, the roll member 8 is rotatably attached to the shaft member 88 of the suspension member 82. According to the suspension member 82, the attachment 84 and the like can be easily attached to the field edge member 6, and can be easily removed as well, so that the work can be performed quickly.

By attaching the roll material 8 between the adjacent field edge materials 6 and in the vicinity thereof, the ceiling surface material 4 from the roll material 8 is arranged in the lower part of the field edge material 6 in both holding materials 12 (grooved holding). It can be laid smoothly and accurately between the parts 14).
In the attachment of the roll material 8, all the members such as the suspension rod 86, the shaft member 88, and the roll material 8 are also attached to the attachment 84, and both attachments 84 are locked to the field edge material 6 as they are. , Nuts and the like may be tightened to adjust each part, and the roll material 8 may be arranged. There are various other mounting procedures for the roll material 8, which may be determined according to the situation at the site.

Subsequently, the auxiliary roller 10 is arranged in front of the roll material 8 attached. The auxiliary roller 10 is rotatably attached to the lower part of both field edge members 6.
As shown in FIG. 6, the auxiliary roller 10 is attached to the lower portion between the two field edge members 6 by using the arrangement member 108. The arrangement member 108 includes an angle member 110 obtained by bending a plate member into an L shape, and a fixing member 112 for attaching the angle member 110 to the field edge member 6. The angle member 110 is provided with a hole for mounting in the laterally oriented portion, and an elongated hole 114 elongated vertically is formed in the vertically oriented portion. The fixing member 112 is a member for fixing the arrangement member 108 to the bottom plate portion 20 of the field edge member 6.

Since the auxiliary roller 10 is removed when the laying of the ceiling surface material 4 is completed, it is desirable that the fixing member 112 can be easily attached to and detached from the field edge member 6. Therefore, as a means for fixing the fixing member 112 to the field edge material 6, adsorption by a magnet, adhesion by an adhesive, screwing by a bolt or nut, or the like is appropriate. Here, the magnet 113 is attached to the upper part of the fixing member 112, and the attraction by the magnet 113 is used as the fixing means.

The fixing member 112 has, for example, a form including an upper joint portion, an intermediate side portion, and a lower attachment portion. The fixing member 112 fixes the attachment portion and the lateral portion of the angle member 110 with bolts and nuts, and attaches the angle member 110 to the lower portion of the fixing member 112. The fixing member 112 may cover a part of the side portion and the mounting portion with a cover material.
For example, a plate-shaped magnet 113 that is attracted to the steel field edge member 6 is fixed to the joint portion of the fixing member 112 with an adhesive or the like. In addition, various joint forms with the field edge material 6 can be adopted for the joint portion of the fixing member 112, such as for bonding or for screwing with screws, bolts and nuts, and the like.

The auxiliary roller 10 is rotatably attached to the lower side of the field edge member 6 by using the arrangement member 108. In the arrangement of the auxiliary roller 10, the arrangement member 108 is attached to the field edge material 6 at the place where the roll material 8 is arranged. First, the fixing member 112 (with the angle member 110 already attached) of the arrangement member 108 is installed and fixed at the lower part (bottom plate portion 20) of the corresponding position of the field edge member 6.
The fixing member 112 can be easily attached to and fixed to the field edge member 6 by the attraction of the magnet 113 at the upper part. The arrangement member 108 is similarly installed at the lower part of the corresponding position of the other field edge member 6. These arranging members 108 are arranged so that the vertically oriented portions of the lower both angle members 110 face each other.

Next, the shaft member 41 is inserted into the through hole provided in the shaft portion of the auxiliary roller 10. Then, each end of the shaft member 41 protruding from the through hole of the auxiliary roller 10 is inserted into the elongated hole 114 of the double-angle member 110, respectively. The height of the auxiliary roller 10 can be adjusted up and down within the range of the elongated hole 114.
Then, when the vertical position of the auxiliary roller 10 is determined, the nut 116 is screwed into the end portion of the shaft member 41, and the shaft member 41 is fixed at a predetermined position of the elongated hole 114. The nut 116 is screwed from both the inside and outside of the elongated hole 114.

The auxiliary roller 10 is rotatable around the shaft member 41 in a state where the arrangement member 108 to which the auxiliary roller 10 is attached is fixed to the lower part of the field edge member 6.
By attaching the roll material 8 and the auxiliary roller 10 at predetermined positions between the adjacent field edge materials 6, the ceiling surface material 4 from the roll material 8 is smoothly attached to the groove-shaped holding portion 14 by the front holding material 12. And it can be placed quickly.

Further, a guide piece 81 that guides the ceiling surface material 4 to the groove-shaped holding portion 14 is attached to the lower portion of the groove-shaped holding portion 14 of the holding material 12. The guide piece 81 is a narrow plate-shaped short material, and is made of a flexible plate-shaped rubber material, a synthetic resin material, or a metal material. The guide piece 81 is attached to the lower end of the holding material 12 by using an adhesive or the like. The other end of the guide piece 81 is curved downward due to the flexibility of the guide piece 81 and is positioned in the vicinity of the auxiliary roller 10.

Next, a construction method of the ceiling surface material will be described based on FIG. 3 and the like. Regarding the construction of the ceiling surface material 4 on the ceiling portion 2, the feeding and transport laying of the ceiling surface material 4 are mainly performed by the workers. As described above, the holding material 12 is attached to the field edge material 6 erected on the ceiling portion 2 along the lower part of the field edge material 6.
The ceiling surface material 4 is continuously transported and arranged from the vicinity of the wall edge 78 on one side of the ceiling 2 toward the wall edge 78 on the other side facing the wall edge 78.

Then, the ceiling surface material 4 is paid out from the arranged roll material 8, and the ceiling surface material 4 passes through the upper part of the auxiliary roller 10 arranged in front of the roll material 8. At this time, the auxiliary roller 10 rotates as the ceiling surface material 4 passes, and at the same time, the auxiliary roller 10 changes the traveling direction of the ceiling surface material 4 to a direction close to horizontal to guide the ceiling surface material 4.

Further, since the lower surface of the ceiling surface material 4 has a corrugated shape and the surface of one auxiliary roller 10 is formed in a gear shape with a corrugated plate attached over the entire circumference, the two are in good mesh with each other. Therefore, when the ceiling surface material 4 passes over the upper part of the rotating material 40 of the auxiliary roller 10, they are engaged with each other and the ceiling surface material 4 can be smoothly conveyed.

At the tip (front part) of the auxiliary roller 10, a holding material 12 is arranged below the field edge member 6, and slightly in front of the auxiliary roller 10, the front side of the holding material 12 (grooved holding part 14). The end of is located. A guide piece 81 is attached to the lower portion of the groove-shaped holding portion 14 of the holding material 12 in a downwardly curved state. Therefore, the ceiling surface material 4 (edge portion 5) smoothly passes through the upper surface portion of the guide piece 81, and the ceiling surface material 4 is guided by the guide piece 81 to the groove-shaped holding portion 14.
The distance between the adjacent holding materials 12 is about the same as the width of the ceiling surface material 4, and the ceiling surface material 4 can be arranged between the holding materials 12 as it is, and can be fitted into the groove-shaped holding portion 14. it can.

The ceiling surface material 4 drawn out from the roll material 8 passes through the upper part of the auxiliary roller 10 and is conveyed, and the left and right edge portions 5 of the end portion 66 (tip portion) of the ceiling surface material 4 are each of the field edge material 6. It is inserted (fitted) into the groove-shaped holding portion 14 by the lower holding material 12 and moved forward. At this time, the orientation of the ceiling surface material 4 is changed by the auxiliary roller 10, and the ceiling surface material 4 can be conveyed toward the groove-shaped holding portion 14 at an angle close to horizontal, and can be easily inserted into the groove-shaped holding portion 14. Work can be speeded up.
At this time, the guide piece 81 naturally guides the ceiling surface material 4 to the groove-shaped holding portion 14, so that the ceiling surface material 4 can be easily transported. Further, since the distance between the roll material 8 and the auxiliary roller 10 can be set to a relatively short distance, the ceiling surface material 4 can be smoothly transferred from the roll material 8 to the auxiliary roller 10.

Then, while the ceiling surface material 4 is unwound (rewound) from the roll material 8, the edge portion 5 is pushed in the depth direction along the groove-shaped holding portion 14, and the holding material 12 is directed toward the elongated direction (front). Transport. In this way, the ceiling surface material 4 is pushed and moved and conveyed until the end portion 66 of the ceiling surface material 4 reaches the front end portion of both the left and right holding members 12, that is, the wall edge portion on the other side.
As a result, the ceiling surface material 4 is supported by fitting both edge portions 5 into the groove-shaped holding portions 14 of the holding material 12, respectively, and the ceiling surface material 4 is supported from the wall edge portion 78 on one side of the ceiling portion 2 to the other side. It is placed near the wall.

FIG. 7 shows a state in which the transport jig 120 is used to assist the transport of the ceiling surface material 4. In this transport jig 120, the corrugated sheet material 124 is fixed to the upper surface of the flat rectangular plate material 122 by adhesion or the like. The corrugated sheet material 124 is a corrugated sheet material formed in a corrugated shape having a cross-sectional shape similar to the corrugated shape of the ceiling surface material 4. Further, a U-shaped handle portion 126 for gripping and operating is attached to the lower portion of the plate member 122.

Normally, the corrugated sheet material of the ceiling surface material 4 is relatively brittle, and therefore, if it is pulled unnecessarily, it may be damaged. Therefore, when the ceiling surface material 4 is transported along the field edge material 6, the transport jig 120 is pressed from below the ceiling surface material 4, and the transport jig 120 is pressed against the corrugated surface of the ceiling surface material 4. The corrugated sheet material 124 is meshed, the transfer jig 120 is operated as it is in the transfer direction, and the ceiling surface material 4 is pulled and conveyed. As a result, the ceiling surface material 4 can be easily conveyed without breaking the corrugated shape of the ceiling surface material 4.

In particular, in the vicinity of the wall edge portion 78 of the ceiling portion 2, it is troublesome to convey the end portion 66 of the ceiling surface material 4. In this case, by using the transfer jig 120, the end 66 of the ceiling surface material 4 can be easily transported toward the holding material 12z of the wall edge 78, and the end 66 of the ceiling surface material 4 can be easily stored in the holding material 12z. be able to.

Further, when the ceiling surface material 4 is conveyed along the field edge material 6, it is also an effective means to use a wire material such as a thread or a string. In this case, for example, as shown in FIG. 8, hook holes (here, two locations) are provided at the tip 66 of the ceiling surface material 4, and the wire 128 extends from the intermediate portion of the wire connecting the holes. , The other end of the wire 128 is arranged in a state of being extended to the wall edge 78 of the transport destination.
Then, by pulling the wire rod 128 from the transport destination, the tip portion 66 of the ceiling surface material 4 can be easily transported, and this can be stored in the holding material 12z of the wall edge portion 78.
When pulling the wire 128, for example, a pulley 129 is attached to a field edge receiving material 72 or the like as shown in the figure, the direction of the wire 128 is changed downward by the pulley 129, and this is pulled from the floor surface or the like to pull the ceiling surface material 4 It is also effective to transport.
Since the ceiling portion 2 has a height from the ground, when the ceiling surface material 4 is transported along the field edge material 6, it is difficult to transport the intermediate portion, but by using the wire rod, the ceiling portion 2 can be transported. The ceiling surface material 4 can be easily transported to the other wall edge portion 78.

Next, the coil spring 100 used for the suspension member 82 will be described. The coil spring 100 expands and contracts up and down according to the load from the shaft member 88 on which the roll member 8 is placed. At the beginning of feeding out the roll material 8, the coil spring 100 contracts because the weight of the roll material 8 is relatively heavy, and the roll material 8 is located relatively downward. Then, after a large amount of the ceiling surface material 4 is unwound from the roll material 8, the weight of the roll material 8 becomes lighter by that amount, so that the coil spring 100 extends, and the roll material 8 is pushed upward and moves together with the shaft member 88.

As a result, the radius of the roll material 8 becomes smaller according to the amount of feeding of the ceiling surface material 4 from the roll material 8, and the feeding position 101 of the ceiling surface material 4 is relatively lowered, while the weight of the roll material 8 is reduced. As a result, the coil spring 100 expands and the roll material 8 is pushed up.
Therefore, the absolute position of the ceiling surface material 4 on the upper surface of the roll material 8 is relatively constant, and the positional relationship between the roll material 8 feeding position 101 and the height position of the auxiliary roller 10 is relatively constant. Is kept relatively constant.

Then, the ceiling surface material 4 unwound from the roll material 8 is conveyed toward the upper portion of the auxiliary roller 10 ahead of the roll material 8, but since the height relationship between the two is kept constant, the ceiling surface material 4 is unwound. The angle and the like are also maintained constant, and the ceiling surface material 4 can be fed out and transported in harmony without any change, which also contributes to workability. Further, since the coil spring 100 has an action of elastically holding the extension of the ceiling surface material 4, an appropriate tension is maintained in the ceiling surface material 4, and the effect of preventing the ceiling surface material 4 from loosening or the like is obtained. is there.

When the arrangement of the ceiling surface material 4 up to the end of the field edge material 6 (holding material 12) on the other side of the wall is completed, the auxiliary roller 10 is first removed from the field edge material 6. In this case, since the auxiliary roller 10 is attached by the attraction of the magnet provided on the fixing member 112, this removal can be easily performed.
Then, a part of the ceiling surface material 4 is left because the ceiling surface material 4 is not arranged such as the mounting position of the auxiliary roller 10 and the roll material 8. Therefore, the ceiling surface material 4 having a corresponding length is drawn out from the roll material 8 and cut at a predetermined position.

After that, the roll material 8 on which the ceiling surface material 4 remains is removed. As for the roll material 8, the fitting 84 or the like which is attached to and engaged with the field edge material 6 can be easily removed by removing the engaging piece portion 92 from the field edge material 6.
Then, the holding material 12 is attached to the lower part of the field edge material 6 at the unarranged portion, and the ceiling surface material 4 is arranged. In this case, the ceiling surface material 4 is first arranged below the field edge material 6, the holding material 12 is pressed against the bottom plate portion 20 of the field edge material 6 from below, and the holding material 12 is kept as it is at the bottom plate portion of the field edge material 6. Screw on 20. As a result, the ceiling surface material 4 can be easily arranged in the non-arranged portion.

Further, the end portion 66 (rear end portion) obtained by cutting the ceiling surface material 4 is arranged at the wall edge portion 78, and in order to hold this, a holding member 12 (12z) is attached to the wall edge portion 78 on one side. The holding member 12 of the wall edge portion 78 is arranged in a direction orthogonal to the field edge member 6, and is erected between the adjacent field edge members 6. In this case, the top portion 46 of one end of the holding material 12 is screwed to the bottom plate portion 20 of one field edge material 6 with a fastener 54, and the other end portion of the holding material 12 is similarly screwed to the other field edge material 6. Is screwed and erected. Then, the end portion 66 of the ceiling surface material 4 is housed in the holding material 12 and supported.
By using the transport jig 120 when moving and transporting the ceiling surface material 4, it is possible to easily move and transport the ceiling surface material 4 and transport the ceiling surface material 4 to the wall edge portion 78, and the ceiling surface material 4 The end 66 can be easily accommodated in the holding material 12 (12z).

Regarding the end portion 66 of the ceiling surface material 4 at the wall edge portion on the other side of the ceiling portion 2, the holding material 12 is similarly arranged on the wall edge portion on the other side, and the end portion 66 of the ceiling surface material 4 is housed therein. Make them support.
As the holding material 12 at the wall edge, a holding material 12z having a Z-shaped cross section is mainly used. The holding material 12z has a shape of one half of the holding material 12a having a hat-shaped cross section, and the top portion thereof is fixed to the bottom plate portion 20 of the field edge material 6.

In this way, the ceiling surface material 4 is arranged and supported between the adjacent field edge members 6 of the ceiling portion 2 and the wall edge portions 78 on one side and the other side of the ceiling portion 2, and the other adjacent field edge members 6 are arranged. Similarly, the ceiling surface material 4 is arranged, and the ceiling surface material 4 is arranged and laid over the entire ceiling portion 2.
