Description

  The present invention relates to a method for attaching a ceiling panel of a building unit.

  There is a unit construction method that enables building to be built in a short period of time by transporting building units pre-manufactured at a manufacturing factory to a building site and combining them at the building site.

  Building units used in the unit construction method include wooden units, and the wooden units have a rectangular parallelepiped shape with a ceiling panel attached to the upper part of the wall panel erected from the side of the floor panel. (For example, refer to Patent Document 1).

  In Patent Document 1, a manufacturing unit manufactures a building unit in a state in which a ceiling panel is temporarily fixed to an upper portion of a wall panel using a temporary fixing metal fitting having a substantially right triangle shape called a cane or the like. It was.

  After the building unit is brought into the building site, for example, the height of the ceiling panel is adjusted using the height adjustment function provided in the temporary fixing bracket, and then the ceiling panel is permanently fixed to the wall panel. However, the temporary fixing metal fittings were removed. In this way, by permanently fixing the ceiling panels at the construction site, for example, height adjustment between the ceiling panels can be performed after the building units are arranged adjacent to each other.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 21 are for explaining this embodiment.

  <Configuration> The configuration will be described below.

  The unit construction method enables building (unit building) to be constructed in a short period of time by transporting building units manufactured in advance at a manufacturing factory to a building site and combining them at the building site.

  In such a unit construction method, a wooden building unit 1 (woody unit) as shown in FIG. 1 is used. The building unit 1 has a rectangular parallelepiped shape in which a ceiling panel 6 is attached to the upper part of wall panels 4 and 5 erected from the side of the floor panel 2.

  Here, the floor panel 2 is made into the substantially rectangular shape etc. which affixed the floor surface material with respect to the at least upper surface of the floor frame material assembled in the rectangular shape. Moreover, the wall panels 4 and 5 are made into the substantially rectangular shape etc. which stuck the wall surface material on both surfaces of the wall frame material assembled in the rectangular shape. The wall panels 4 and 5 have different sizes on the girder side (long-side wall panel 4) and the wife side (short-side wall panel 5). And the ceiling panel 6 is made into the substantially rectangular thing etc. which affixed the ceiling surface material with respect to the at least lower surface of the ceiling frame material assembled in the rectangular shape. A heat insulating material or the like can be attached to the floor panel 2, the wall panels 4, 5 and the ceiling panel 6 as necessary. Details of the floor panel 2, the wall panels 4 and 5, and the ceiling panel 6 will be described as necessary.

  And with respect to the basic configuration as described above, in this embodiment, the method of attaching the ceiling panel 6 to the building unit 1 (ceiling panel attaching method) is as follows.

(1) When the building unit 1 is manufactured by attaching the ceiling panel 6 to the upper part of the wall panels 4 and 5 erected from the side of the floor panel 2, as shown in FIG. A positioning jig 11 having a length corresponding to the mounting position is placed in contact with the inner surface of the wall panels 4 and 5 in an upward direction from the position of the floor panel 2, and as shown in FIG. A positioning piece 12 serving as a reference for the mounting position of the ceiling panel 6 is placed on the upper end of the tool 11, and the positioning piece 12 is fixed to the wall panels 4 and 5 as shown in FIGS. A single attachment process is performed.
Next, as shown in FIGS. 8 and 9, the ceiling panel 6 is placed on the positioning piece 12 from the upper side, and the ceiling panel 6 is temporarily held at a predetermined mounting position with respect to the wall panels 4 and 5 and positioned. A ceiling panel positioning process is performed.
Then, as shown in FIG. 10, a ceiling panel fixing process is performed in which the ceiling panel 6 temporarily held and positioned on the upper portion of the positioning piece 12 is fixed (mainly fixed) to the upper portions of the wall panels 4 and 5.
Furthermore, as shown in FIG. 11, after the ceiling panel 6 is fixed to the wall panels 4, 5, a positioning piece removal step of removing the positioning pieces 12 from the wall panels 4, 5 is performed. That is, in the manufacturing factory, the ceiling panel 6 is permanently fixed by sequentially performing the positioning piece attaching process → the ceiling panel positioning process → the ceiling panel fixing process → the positioning piece removing process.

  Here, as shown in FIG. 11, the mounting position of the ceiling panel 6 is assumed to be near the upper edge of the inner surface side of the wall panels 4 and 5 in the building unit 1 to which the positioning piece 12 is attached. The upper surface of the ceiling panel 6 is the same as or lower than the upper edges of the wall panels 4 and 5. In this embodiment, the ceiling panel 6 is attached until the main panel is fixed to the wall panels 4 and 5. In the conventional case, as shown in FIG. The building unit 1 was manufactured in a state of being temporarily fixed around the upper edge of the wall panels 4 and 5 using a temporary fixing metal fitting 101 having a substantially right triangle shape in side view. Therefore, it is structurally possible that the ceiling panel 6 is attached to the position of the lower edge of the building unit 1A (see FIG. 10) installed on the upper side of the building unit 1 to which the ceiling panel 6 is temporarily fixed. there were. However, in this embodiment, the ceiling panel 6 is always attached in the vicinity of the upper edge of the building unit 1 to which the positioning piece 12 is attached.

  FIG. 10 shows the internal structure of the wall panel 4. The wall panel 4 is obtained by attaching a face material 4c to the inner surface of a wall frame material composed of a vertical frame material 4a and a horizontal frame material 4b. Similarly to the wall panel 4, the wall panel 5 also has a face material 5 c attached to the inner surface of the wall frame material composed of the vertical frame material 5 a and the horizontal frame material 5 b. The internal structure of the ceiling panel 6 is also shown. The ceiling panel 6 is configured such that a face material 6c is attached to the lower surface of a ceiling frame material composed of an end frame material 6a (edge field edge) and a side frame material 6b (side field edge). However, the structure of the wall panels 4 and 5 and the ceiling panel 6 is not limited to the above.

  And as shown in FIG. 9, the above-mentioned positioning jig 11 has a rod-like one shorter by the length of the positioning piece 12 than the length from the upper surface of the floor panel 2 to the mounting position of the ceiling panel 6. Is done. The positioning jig 11 can be a square or lumbar material extending in the vertical direction. The positioning piece 12 can be a positioning wooden cross about 10 cm square. However, the size and material of the positioning piece 12 are not limited to the above. The positioning pieces 12 are preferably attached to the positions of the four corners of the building unit 1.

  When positioning the ceiling panel 6, if necessary, as shown in FIG. 8, a support member 14 that supports the position of an intermediate portion of the side portion of the ceiling panel 6 and the like is used for the building unit 1. You may do it.

  Further, when positioning the ceiling panel 6, a positioning bracket 15 for locking and holding the ceiling panel 6 to the upper edge of the wall panels 4 and 5 may be attached to the ceiling panel 6 in advance. For example, the positioning bracket 15 connects the attachment portion with respect to the upper surface of the ceiling panel 6, the engagement portion that can be engaged with the upper edge portions of the wall panels 4 and 5, and the attachment portion and the engagement portion. It can have a connection part. The connecting portion may be a stepped portion having a step amount corresponding to a difference in height level between the attaching portion and the locking portion in the vertical direction. As a result, the positioning fitting 15 has a substantially Z-shape or a step shape when viewed from the side. The support member 14 and the positioning bracket 15 can be removed after use.

  (2) As shown in FIGS. 6 and 7, the positioning piece 12 may be fixed to the wall panels 4 and 5 using a detachable fixture 21.

  Here, FIG. 6 shows a state where the positioning piece 12 is fixed to the wall panel 4 (on the girder side), and FIG. 7 shows a state where the positioning piece 12 is fixed to the wall panel 5 (on the wife side). ing. The fixing tool 21 fixes the positioning piece 12 directly in contact with the wall panels 4 and 5 (the upper part thereof). The detachable fixture 21 can be, for example, a wood screw. By using the detachable fixture 21, the positioning piece 12 can be attached and detached. Therefore, as shown in FIG. 11, the positioning piece 12 can be removed after use.

  As shown in FIG. 6 (a), the fixture 21 has a wall frame member (upper part of the vertical frame member 4a) located at the upper part of the wall panels 4 and 5 (in this case, the wall panel 4) as shown in FIG. It can be screwed from an oblique direction, or can be screwed from a perpendicular direction as shown in FIG. As shown in FIG. 6A, by screwing the fixture 21 from an oblique direction, the work can be performed from a position away from the orthogonal wall panels 4 and 5 (in this case, the wall panel 5). Therefore (distance 25), the screwing work of the fixture 21 becomes easy. On the other hand, as shown in FIG. 6B, when the fixture 21 is screwed from the direction perpendicular to the surface, the work is performed at a position close to the orthogonal wall panels 4 and 5 (in this case, the wall panel 5). However (distance 26 <distance 25), it becomes possible to securely screw the fixture 21 deeply into the vertical frame member 4a. In addition, when screwing from the diagonal direction as shown in FIG. 6A, it is necessary to use a longer fixture 21 than when screwing from the perpendicular direction as shown in FIG. 6B. In the case of FIG. 6B, the distance 26 from the face material 5c to the fixture 21 is about 12 mm. In the case of FIG. 6A, the distance 25 from the face material 5c to the fixture 21 is 12 mm or more.

  In the case of FIGS. 7A and 7B, the mounting position and the number of the fixtures 21 are changed according to the configuration of the vertical frame member 5a of the wall panels 4 and 5 (in this case, the wall panel 5). I am doing so. That is, as shown in FIG. 7A, when the vertical frame member 5a of the wall panels 4 and 5 has a triple stud structure, the fixtures 21 are respectively attached to the two outer stud members. I am doing so. Further, as shown in FIG. 7B, when the vertical frame member 5a has a double stud structure, the fixture 21 is attached to each of the outer stud members. However, the mounting position and the number of use of the fixing tool 21 are not limited to the above.

  (3) As shown in FIG. 12, the ceiling panel 6 may be fixed to the wall panels 4 and 5 by using a detachable fixture 31.

  Here, the fixture 31 is used for directly fixing the ceiling panel 6 to the wall panels 4 and 5. The detachable fixture 31 can be, for example, a wood screw. The detachable fixing tool 31 is screwed almost straight (in this case, substantially in the horizontal direction) with respect to a wall frame member (vertical frame members 4a, 5a, etc.) located above the wall panels 4 and 5. To do. As described above, by using the detachable fixture 31, the ceiling panel 6 can be partly or entirely attached and detached. Therefore, the height adjustment (fine adjustment) of the ceiling panel 6 can be performed when necessary at the construction site. For example, as shown in FIG. 13, the step adjustment between the adjacent ceiling panels 6 is performed within the range of the adjustment allowance 35 of about 6 mm at the maximum.

  (4) As shown in FIG. 14, when the building unit 1 has an open surface 41 where the wall panel 4 is not provided, the ceiling panel 6 reaches the end 42 on the open surface 41 side of the building unit 1. It's okay. And you may make it attach the edge part 43 of the ceiling panel 6 according to the position of the edge part 42 by the side of the open surface 41 of the building unit 1. FIG.

  Here, the building unit 1 is basically a closed type having four wall panels 4 and 5, but it can be an open type by opening one or two sides. In this case, one side of the girder side is opened. The end portion 42 on the open surface 41 side of the building unit 1 is an end edge portion (on the open surface 41 side) of the wall panel 5 located on both sides of the open surface 41. Up to now, as shown in FIG. 15, the edge 43 a of the ceiling panel 6 has been structured to be retracted and attached rather than the position of the end 42 on the open surface 41 side of the building unit 1 (retraction amount 45). ). The pull-in amount 45 was about 14 mm, for example. Therefore, as shown in FIG. 16, when the building units 1 having the open surfaces 41 are installed side by side, the interval between the adjacent ceiling panels 6 is separated with a wide interval of about 28 mm or more. Therefore, it is difficult to adjust the level difference between the adjacent ceiling panels 6.

  (5) Further, as shown in FIGS. 17 and 18, when a gap 51 is generated between the ceiling panel 6 and the wall panels 4 and 5, a spacer 52 may be interposed in the gap 51. .

Here, for example, in the case of an open-type building unit 1 having a U-shape in a plan view without one of the wall panels 4 on the girder side as shown in FIG.
(Procedure A) First, align with the wall panel 4 on the girder side,
(Procedure B) Next, according to one of the wall panels 5 on the wife side (outside wall 501),
(Procedure C) Finally, it is preferable to perform alignment in the horizontal direction in the order of matching with the other of the wife side wall panels 5 (inner wife wall 502). Therefore, since the gap 51 is mainly generated on the inner gutter wall 502 side, the spacer 52 is interposed at least on the portion of the gap 51 between the inner gutter wall 502 and the ceiling panel 6 to which the fixture 31 is attached. I will let you.

Further, for example, in the case of an open-type building unit 1 in a plan view D-shape without both the girder-side wall panels 4 as shown in FIG.
(Procedure A) First, the edge 43 is aligned with the position of the end 42 on the one open surface 41 side of the building unit 1.
(Procedure B) Next, according to one of the wall panels 5 on the wife side (outside wall 501),
(Procedure C) Finally, it is preferable to perform alignment in the horizontal direction in the order of matching with the other of the wife side wall panels 5 (inner wife wall 502). Therefore, since the gap 51 is mainly generated on the inner gutter wall 502 side, the spacer 52 is interposed at least on the portion of the gap 51 between the inner gutter wall 502 and the ceiling panel 6 to which the fixture 31 is attached. I will let you.

  The spacer 52 may be installed when the gap 51 of 3 mm or more is generated, for example.

  <Functional Effects> The operational effects of this embodiment will be described below.

  In the unit method, the building unit 1 is manufactured in advance at the manufacturing factory, the manufactured building unit 1 is transported to the building site, and the building unit 1 is combined at the building site, so that the building (unit building) can be assembled in a short period of time. Can be built.

  The building unit 1 used in the unit method is manufactured by attaching the ceiling panel 6 to the upper part of the wall panels 4 and 5 erected from the side of the floor panel 2 at the manufacturing factory.

  (Operation Effect 1) At this time, the positioning piece 12 placed on the upper end of the positioning jig 11 having a length corresponding to the mounting position of the ceiling panel 6 is fixed to the wall panels 4 and 5. Thereby, the positioning piece 12 can be attached to the wall panels 4 and 5 easily and accurately.

  The ceiling panel 6 is placed on top of the positioning pieces 12 fixed to the wall panels 4 and 5. Accordingly, the ceiling panel 6 can be temporarily held at a predetermined mounting position, and the ceiling panel 6 can be easily and accurately positioned.

  Therefore, there is no need to hold the ceiling panel 6 temporarily held and positioned on the upper part of the positioning piece 12, so that it can be easily and accurately fixed to the upper part of the wall panels 4 and 5 in the height direction and the horizontal direction. can do. For example, the ceiling panel 6 having a height of about 2.4 m to 3 m from the position of the floor panel 2 can be attached with an accuracy of ± 2 mm. Therefore, the quality of the building unit 1 can be improved.

  Furthermore, the positioning piece 12 is removed from the wall panels 4 and 5 after the ceiling panel 6 is fixed to the wall panels 4 and 5. Thereby, the ceiling panel 6 can be attached without leaving a trace of the positioning piece 12.

  As a result, the ceiling panel 6 can be permanently fixed in the manufacturing factory, and the work process in the manufacturing factory can be rationalized.

  And, when the ceiling panel 6 is permanently fixed at the construction site as before, the ceiling panel 6 is temporarily fixed until the building unit 1 is carried into the construction site. Temporary fastening metal fittings 101 (see FIG. 21) called canes or the like were used. However, by temporarily fixing the ceiling panel 6 at the manufacturing factory, the temporary fastening metal fittings 101 (such as the above-mentioned cane) (FIG. 21). The cost of parts can be reduced.

  In addition, by fixing the ceiling panel 6 at the building unit 1 manufacturing plant, the building unit 1 is built up at the construction site, and the ceiling panel 6 is permanently fixed to temporarily fix the bracket such as a cane. The number of carpenters can be reduced when removing 101 or the like.

  Furthermore, since the factory of the building unit 1 is fixed up to the main fixing of the ceiling panel 6, for example, the electrical wiring that has been performed after installing the roof on the building unit 1 at the construction site so far. Work can be done before the roof is installed at the construction site, and waiting for electrical work can be eliminated. In addition, various operations that have been performed after the main fixing of the ceiling panel 6 at the construction site can be performed at the manufacturing factory after the main fixing of the ceiling panel 6 at the manufacturing factory. As a result, it is possible to reduce the work on the construction site and to construct the building more efficiently.

  In addition, since the ceiling panel 6 is permanently fixed at the manufacturing unit of the building unit 1, the ceiling work at the construction site can be reliably performed on the ceiling panel 6 that is permanently fixed. Therefore, the safety of the ceiling work can be improved.

  (Operation Effect 2) In addition to the above, the positioning piece 12 may be fixed to the wall panels 4 and 5 by using a detachable fixture 21. Thereby, after fixing the ceiling panel 6 to the wall panels 4 and 5, the positioning piece 12 can be easily removed from the wall panels 4 and 5 by removing the detachable fixture 21.

  (Operation Effect 3) In addition to the above, the ceiling panel 6 may be fixed to the wall panels 4 and 5 by using a detachable fixing tool 31. Thereby, when the building unit 1 is installed adjacent to the building site, even if a step is generated between the ceiling panels 6 of the adjacent building units 1, Since the fixed state of the ceiling panel 6 with respect to the wall panels 4 and 5 can be partially released by removing the portion, each of the steps can be eliminated by reattaching the ceiling panel 6 to an appropriate position. It becomes possible to easily adjust the height of the ceiling panel 6.

  (Effect 4) In addition to the above, the edge 43 of the ceiling panel 6 may be attached in accordance with the position of the end 42 on the open surface 41 side of the building unit 1. Accordingly, as shown in FIGS. 15 and 16, it is not necessary to retract the edge 43 of the ceiling panel 6 from the end 42 on the open surface 41 side of the building unit 1, so that the ceiling panel 6 mounting structure is As well as being easy, the troublesome dimensioning work (to accurately retract the edge 43 of the ceiling panel 6) is eliminated, and the alignment of the edge 43 of the ceiling panel 6 is facilitated. The work man-hours and work time can be reduced accordingly.

  Moreover, the vertical frame material of the wall panel 5 located in the both sides of the open surface 41 of the building unit 1 by attaching the edge part 43 of the ceiling panel 6 according to the position of the edge part 42 by the side of the open surface 41 of the building unit 1. The positioning piece 12 and the periphery of the edge 43 of the ceiling panel 6 can be attached by effectively using 5a and the like. Therefore, the positioning piece 12 and the periphery of the edge 43 of the ceiling panel 6 can be firmly fixed to the vertical frame member 5a of the wall panel 5 on both sides of the open surface 41, which is structurally advantageous. In addition, since the vertical frame member 5a is reliably present on the back side, it is possible to prevent the positioning piece 12 and the periphery of the edge 43 of the ceiling panel 6 from being broken, which is structurally advantageous. .

  On the other hand, when the edge 43 of the ceiling panel 6 is attached in a state of being retracted with respect to the end 42 on the open surface 41 side of the building unit 1, the position of the wall panel 5 where the vertical frame member 5 a is not provided. Therefore, there is a high risk that the positioning piece 12 and the periphery of the edge 43 of the ceiling panel 6 will be attached. Therefore, it is difficult to secure the mounting strength and it is difficult to prevent cracks, which is structurally disadvantageous.

  Further, according to the above, when the building units 1 having the open surfaces 41 are arranged adjacent to each other at the construction site, the edge portions 43 of the ceiling panels 6 of the adjacent building units 1 are close to each other and are almost abutted with each other. Therefore, compared with the case where the edge portions 43 of the ceiling panel 6 are separated from each other, the step adjustment between the adjacent ceiling panels 6 can be easily performed.

  (Effect 5) In addition to the above, a spacer 52 may be interposed in the gap 51 between the ceiling panel 6 and the wall panels 4 and 5. As a result, the gap 51 between the ceiling panel 6 and the wall panels 4 and 5 is filled with the spacers 52, and the ceiling panel 6 and the wall panels 4 and 5 are firmly attached by the spacers 52. It is possible to prevent backlash in the vertical direction and horizontal direction.

  As mentioned above, although embodiment of this invention has been explained in full detail with drawing, embodiment is only an illustration of this invention. Therefore, the present invention is not limited only to the configuration of the embodiment, and it goes without saying that design changes and the like within a scope not departing from the gist of the present invention are included in the present invention. Further, for example, when each embodiment includes a plurality of configurations, it is a matter of course that possible combinations of these configurations are included even if not specifically described.
