By the way, when construction accuracy is bad, unevenness may occur in the support structure. In order to absorb this unevenness, the support structure was marked with a reference line, and a ceiling base such as a field edge was joined with a screw in accordance with the reference line. For this reason, there is a problem that the portion where the unevenness is large has a small overlapping portion between the support structure and the ceiling base and is difficult to join.
Furthermore, when joining, such as screwing, the work must be performed with the ceiling foundation pressed down, so that the work is complicated and a lot of labor is required.

  From such a point of view, an object of the present invention is to provide a ceiling foundation fixing bracket that can easily adjust the height of the support position of the ceiling foundation and can be joined.

  A ceiling foundation fixing bracket according to an embodiment of the present invention will be described in detail with reference to the drawings. In the present embodiment, a case where the ceiling base fixing bracket is applied to an inclined ceiling will be described as an example.

  As shown in FIG. 1, the ceiling foundation fixture 1 according to this embodiment directly fixes a ceiling foundation 20 to a support structure 10. In the present embodiment, the ceiling base 20 is supported by the ceiling base 20 by joining (for example, screwing) the ceiling base fixing bracket 1 to the support structure 10 and by joining (for example, screwing) the ceiling base 20 to the ceiling base fixing bracket 1. It is fixed directly to the body 10. The joining method is not limited to screwing, and other joining methods such as nail fastening and welding may be used.

  The support structure 10 is suspended from the building structure 2 such as a beam. The support structure 10 includes a plurality of suspension members 11 extending downward from the beam, a first horizontal member 12 attached to a lower end portion of the suspension member 11, and a lower end portion of the first horizontal member 12. And a second horizontal member 13 attached thereto. The first horizontal member 12 is bridged via brackets 14 below the plurality of suspension members 11, 11. The second horizontal member 13 is orthogonal to the first horizontal member 12 in a plan view, and is spanned under the plurality of first horizontal members 12. The second horizontal member 13 is fixed to the first horizontal member 12 via a bracket 12a (see FIG. 3). The second horizontal member 13 is made of, for example, grooved steel with a lip (C-shaped channel).

  As shown in FIGS. 2 and 3, the ceiling base 20 includes, for example, a plurality of field edges 21 and a plurality of field edge receivers 22 arranged orthogonal to the field edges 21 in plan view. . The field edge 21 and the field edge receiver 22 are arranged in a lattice pattern. The field edge 21 is a member that holds the ceiling plate 3 and is disposed on the upper side of the ceiling plate 3. The field edge 21 has, for example, a lip groove shape with a C-shaped cross section, and is arranged so that the web is on the lower side. The ceiling plate 3 is in contact with the lower surface of the field edge 21, and the ceiling plate 3 is fixed by a fixing jig such as a screw (not shown).

  The field edge receiver 22 is a member that holds the field edge 21, and is disposed on the upper side of the field edge 21. The field edge receiver 22 is made of, for example, a channel material having a groove shape in cross section, and is disposed in a state where the pair of flanges 22a and 22b are positioned vertically and the web 22c is standing. The field edge receiver 22 is connected to the field edge 21 with the lower flange 22b in contact with the lip 21a on the upper surface of the field edge 21. The field edge 21 and the field edge receiver 22 are connected via a known connection fitting 23.

  As shown in FIGS. 2 and 3, the ceiling base fixture 1 includes a first member 30 that is locked to the second horizontal member 13 of the support structure 10 and a field receiver 22 of the ceiling base 20. And a second member 50 to be stopped. The second member 50 is attached to the first member 30 such that the attachment height can be adjusted.

  As shown in FIGS. 4 to 7, the first member 30 includes a support structure fixing portion 31 and a second member fixing portion 32. The first member 30 is formed by bending a steel plate material. The support structure fixing portion 31 is a part for hooking the ceiling base fixing bracket 1 to the second horizontal member 13 and screwing. The support structure fixing portion 31 has a U-shaped cross-section, and includes an upper plate portion 31a, a distal end bent portion 31b, and a proximal end bent portion 31c.

  The upper plate portion 31 a is placed on the upper flange 13 a of the second horizontal member 13. The upper plate portion 31a is disposed along the upper flange 13a of the second horizontal member 13, and covers the upper flange 13a.

  The front end bent portion 31b is bent at a right angle downward from the front end side of the upper plate portion 31a. The tip bent portion 31b is disposed on the lip 13b side of the second horizontal member 13 and is in contact with the surface of the lip 13b. The lower end portion of the tip bent portion 31 b extends below the lower end of the second horizontal member 13. A bolt through hole 33 is formed at the lower end portion of the tip bent portion 31b. The bolt through hole 33 is formed below the lower end of the second horizontal member 13.

  The proximal end bent portion 31c is bent at a right angle downward from the proximal end side (the side where the second member 50 is located) of the upper plate portion 31a. The proximal bent portion 31c is disposed on the back surface 13c side of the second horizontal member 13 and is in contact with the surface of the back surface 13c. The lower end portion of the base end bent portion 31 c extends below the lower end of the field edge receiver 22 disposed below the second horizontal member 13. A screw hole 34 for a screw V1 for fixing the ceiling base fixing bracket 1 to the second horizontal member 13 is formed in the base end bent portion 31c. The screw holes 34 are formed at a total of four locations, two in the upper and lower stages, at positions where they contact the back surface 13c of the second horizontal member 13. The periphery of the screw hole 34 is a joint for joining to the second horizontal member 13 (joining to the support structure 10).

  Bolt through holes 35 are formed in the base end bent portion 31c. The bolt through hole 35 is configured by a screw hole, and is formed at a position coaxial with the bolt through hole 33 of the tip bent portion 31b. An opening preventing bolt 36 that passes under the second horizontal member 13 is inserted into the bolt through holes 33 and 35. The opening prevention bolt 36 prevents the bent portions 31b and 31c from opening each other by keeping the distance between the distal end bent portion 31b and the proximal end bent portion 31c constant. Further, since the opening prevention bolt 36 surrounds the second horizontal member 13 by the upper plate portion 31a, the distal end bent portion 31b, and the proximal end bent portion 31c, the ceiling base fixing bracket 1 is the second This prevents the horizontal member 13 from coming off.

  The second member fixing portion 32 is a part for fixing the second member 50 and joining the field receiver 22. In this embodiment, the field edge receiver 22 is screwed to the second member fixing portion 32. The second member fixing portion 32 is raised at a right angle from one end in the lateral width direction (longitudinal direction of the second horizontal member 13) of the proximal bent portion 31c (side surface of the support structure fixing portion 31). That is, the second member fixing portion 32 is continuously orthogonal to the proximal bent portion 31c. The second member fixing portion 32 extends in a direction orthogonal to the back surface 13 c of the second horizontal member 32. The second member fixing portion 32 is formed with a screw hole 37 for the screw V2 for fixing the field receiver 22. The periphery of the screw hole 37 is a joint for joining the field receiver 22. The screw holes 37 are formed at four positions at the apex of the rhombus. At least three screw holes 37 are arranged so as to abut on the web 22c of the field receiver 22 whose position is adjusted up and down. Specifically, when the mounting height of the second member 50 to the first member 30 is an intermediate position, the four screw holes 37 abut against the web 22c of the field receiver 22. When the mounting height of the second member 50 to the first member 30 is a high position, the upper three screw holes 37 abut against the web 22c of the field receiver 22. When the mounting height of the second member 50 to the first member 30 is low, the lower three screw holes 37 abut against the web 22 c of the field edge receiver 22. The number and arrangement of the screw holes 37 are not limited to the above configuration, and may be set as appropriate according to conditions such as the weight of the ceiling material 3. A bolt through hole 38 is formed in the second member fixing portion 32. The bolt through hole 38 is configured by a screw hole, and a bolt B for fixing the second member 50 is screwed therein.

  The second member 50 is fixed to the second member fixing portion 32 with the field receiver 22 locked. The second member 50 is formed by bending a steel plate material. The second member 50 has a U-shaped cross section in a plan view, and includes a back surface portion 51 and a pair of side surface portions 52 and 52.

  The back surface portion 51 has a vertically long rectangular shape with a left-right width dimension equivalent to that of the second member fixing portion 32. A bolt through hole 53 is formed in the back surface portion 51. The bolt through hole 53 is configured by a long hole extending in the vertical direction. A bolt B for fixing the second member 50 to the first member 30 is inserted into the bolt through hole 53. Thus, since the bolt B is inserted through the long hole, the mounting height of the second member 50 can be adjusted with respect to the first member 30. Since the bolt B to be fixed is one, the second member 50 can be fixed in an inclined state with respect to the first member 30. A screw hole 54 is formed below the bolt through hole 53. A screw V3 struck from the second member 50 toward the first member 30 is inserted into the screw hole 54. The screw V3 is struck after adjusting the angle of the second member 50 with respect to the first member 30.

  A bent portion 55 that bends in the same direction as the side surface portion 52 is provided at the upper end of the back surface portion 51. The bent portion 55 serves as a rib that reinforces the back surface portion 51.

  The side surface portions 52 are bent at right angles from both ends of the back surface portion 51 in the width direction. A pair of side surface parts 52 and 52 are the same shapes. The side surface portion 52 extends below the lower end of the back surface portion 51. A slit 56 for locking the field edge receiver 22 is formed in the side surface portion 52. The slit 56 is formed at the lower position of the lower end of the back surface portion 51. The slit 56 has a cut section substantially the same as the cross-sectional shape of the upper flange 22a of the field edge receiver 22, and the flange 22a can be inserted therein. The slit 56 extends in the horizontal direction, and the field receiver 22 is locked to the second member 50 by inserting the flange 22a therein. When the second member 50 is attached to the first member 30, the field receiver 22 is sandwiched between the second member 50 and the second member fixing portion 32 of the first member 30. As a result, the field edge receiver 22 cannot move in the direction in which the slit 56 comes out. That is, the second member fixing portion 32 serves as a prevention portion from the slit 56 of the field edge receiver 22 (ceiling base).

  Next, operational effects will be described while explaining the procedure for attaching the ceiling foundation 20 using the ceiling foundation fixing bracket 1 having the above-described configuration.

  When installing the ceiling foundation 20, first, the first member 30 is lowered from above and locked at a predetermined position of the second horizontal member 13. Thereafter, the opening prevention bolt 36 is attached so that the first member 30 does not fall. In this state, the first member 30 can slide in the longitudinal direction of the second horizontal member 13.

  Next, the second member 50 is brought into contact with the first member 30 in a state where the edge receiver 22 is locked to the slit 56 of the second member 50, and the bolt B is temporarily tightened. Thus, the second member 50 and the field edge receiver 22 are temporarily fixed. At this time, in the field receiver 22, the upper flange 22 a is inserted into the slit 56 and the web 22 c is in contact with the second member fixing portion 32. Therefore, the field edge receiver 22 is sandwiched between the second member fixing portion 32 and the second member 50, and therefore does not fall from the ceiling foundation fixing bracket 1.

  If the second member 50 is temporarily fixed in the ceiling base fixing bracket 1 within a predetermined range, the mounting height of the second member 50 is finely adjusted. Accordingly, the support position of the field receiver 22 is adjusted, so that the field receiver 22 can be installed with high accuracy. Such adjustment of the mounting height of the second member 50 is easily performed since the ceiling base 20 is temporarily fixed, that is, in a state where the field edge receiver 22 is supported by the surrounding ceiling base fixing bracket 1. It can be carried out.

  When the adjustment of the mounting height of the second member 50 (adjustment of the support position of the edge receiver 22) is completed, the first member 30 is fixed to the second horizontal member 13 with the screw V1, and the screw V2 is used. The field receiver 22 is fixed to the first member 30. Further, the second member 50 is fixed to the first member 30 with the screw V3. As a result, the field edge receiver 22 is integrated with the second horizontal member 13 via the first member 30, and the ceiling foundation 20 is directly fixed to the support structure 10.

  Thereafter, the field edge 21 is attached to the field edge receiver 22, and the ceiling board 3 is attached to the field edge 21. Since the position accuracy of the field edge receiver 22 is high, the position accuracy of the field edge 21 and the ceiling board 3 is also increased.

  On the other hand, in the ceiling foundation fixing bracket 1 of the present embodiment, the support structure fixing portion 31 and the second member fixing portion 32 are orthogonal to each other, so that the first member 30 has high rigidity. Moreover, since the bolt insertion hole 53 of the second member 50 is configured by a long hole extending in the vertical direction, the first member can be simply slid in the longitudinal direction of the long hole. The mounting height of the second member 50 relative to 30 can be easily adjusted. At this time, since the second member 50 is held in a state where the bolt B is not pulled out, it does not fall.

  Next, the case where the ceiling base fixture 1 is applied to a curved ceiling will be described. As shown in FIG. 8, the support structure 1 has a first horizontal member 12 spanned below the suspension members 11, 11... Having different heights. The first horizontal member 12 is arranged stepwise in an inclined state or a horizontal state according to the inclination of the ceiling surface. The second horizontal member 13 is fixed to the lower part of the first horizontal member 12. The field edge receiver 25 is curved along the curved surface of the ceiling surface.

  In such a support structure 1, the distance between the second horizontal member 13 and the field edge receiver 25 differs depending on the location. Therefore, the support position of the field receiver 25 is adjusted by changing the mounting height of the second member 50 with respect to the first member 30.

  FIG. 9 illustrates a case where the mounting height of the second member 50 is low. The second member 50 is attached to a lower position with respect to the first member 30, and the bolt B is located at the upper end portion of the bolt insertion hole 53. That is, the upper end portion of the bolt insertion hole 53 has a height corresponding to the bolt insertion hole 38 of the first member 30. If the second member 50 is attached to a low position in this way, the support position of the field edge receiver 25 is lowered, and therefore the distance between the second horizontal member 13 and the field edge receiver 25 can be increased. Along with this, the field edge receiver 25 becomes lower than the second member fixing portion 32. Therefore, the field edge receiver 25 is screwed using the three screw holes 37 on the lower side of the second member fixing portion 32. In the second member fixing portion 32 of FIG. 9, the screw holes 37 are formed at a total of five locations, that is, four vertex positions of the square and one intersection position of the diagonal of the square.

  The field edge receiver 25 of FIG. 9 is configured by a lip grooved steel (C-shaped channel). Therefore, the slit 56a of the second member 50 has a height through which the lip portion 25b of the field edge receiver 25 can pass (see FIG. 9B). A notch 57 into which the lip 25b enters is formed at the tip of the slit 56b. When the lip portion 25b enters the cut portion 57, the upper flange 25a of the field edge receiver 25 is locked to the bottom surface of the slit 56b.

  Since other configurations are the same as those in FIG. 2, the same reference numerals are given and description thereof is omitted.

  FIG. 10 illustrates a case where the second member 50 is attached to the first member 30 while being inclined. When the inclination angles of the second horizontal member 13 and the field edge receiver 25 are different, the second member 50 is attached to be inclined with respect to the second member fixing portion 32 of the first member 30. The second member 50 is inclined around the bolt B. The second member 50 rotates in a direction not interfering with the second horizontal member 13 (right rotation in FIG. 10).

  Also in this case, after the adjustment of the mounting height of the second member 50 (adjustment of the support position of the field edge receiver 22) is completed, the second member 50 is fixed to the first member 30 with the screw V3. Thereby, the inclination angle of the second member 50 is also fixed.

  By tilting the second member 50 with respect to the first member 30 in this manner, the ceiling base 20 is fixed to the support structure 10 in a state where the support structure 10 and the ceiling base 20 are relatively inclined. Can do.

  As mentioned above, although the form for implementing this invention was each demonstrated, this invention is not limited to the said embodiment, A design change, such as a material, a shape, and a magnitude | size, is suitably possible in the range which does not deviate from the meaning of this invention. It is. For example, in the embodiment, the bolt through hole 33 of the first member 30 is a screw hole and the bolt through hole 53 of the second member 50 is a long hole. However, the present invention is not limited to this. The bolt through hole 33 of the first member 30 may be a long hole, and the bolt through hole of the second member 50 may be a screw hole. Moreover, it is good also as a structure tightened by screwing a nut into the front-end | tip part of the volt | bolt B, using a screw hole as a mere through-hole.

  Moreover, in the said embodiment, although the ceiling foundation fixing metal 1 has fixed the field edge receiver 22, it is not limited to this. The ceiling base 20 may be a base material other than the field edge 21 and the field edge receiver 22, for example, a T-bar of the system ceiling.

  Furthermore, although the said embodiment demonstrated the case where a ceiling surface inclined, it is needless to say that it is applicable even if it is a horizontal ceiling surface. Even in this case, there is an effect that the unevenness of the support structure can be absorbed.
