Description

[Technical field]

[0001] The present invention relates to end support fittings for supporting both ends of a ceiling base material that constitutes the ceiling of a building. [Background technology]

[0002] Conventionally, known ceiling structures for buildings include a suspended ceiling, in which ceiling surface materials (hereinafter referred to as "ceiling panels") are suspended from structural frames such as beams, and a vertical ceiling structure, in which ceiling panels are fixed directly to the structural frame above.

[0003] A suspended ceiling prevents vibrations from the upper floor from being transmitted to the floor below. On the other hand, with a straight ceiling structure, the height of the ceiling structure can be reduced, but because the ceiling boards on the first floor are fixed directly to the floor joists on the second floor, vibrations from the second floor are transmitted directly to the floor below.

[0004] The ceiling structure described in the following patent document utilizes a ceiling underlayment made of a metal frame between the floor joists and the ceiling panels in order to prevent the transmission of vibrations from above, and improves the structure of this ceiling underlayment.

[0005] That is, it is a ceiling board fixing structure, in which the ceiling underlayment has a first fixing plate portion fixed to the floor joist via a screw, a second fixing plate portion formed approximately parallel to the first fixing plate portion and to which the ceiling board is fixed via a screw, a connecting plate portion connecting the first fixing plate portion and one end side of the second fixing plate portion, and a rising portion rising from the other end side of the second fixing plate portion toward the floor joist, and the rising portion is characterized in that it extends to a position close to the floor joist.

[0006] [Patent Document 1] JP 2013-32660 A Summary of the Invention [Problem to be solved by the invention]

[0007] FIG. 5 is an explanatory diagram showing a state in which a plurality of the ceiling base materials are fixed to floor joists in approximately parallel relation, and FIG. 6 is an enlarged explanatory diagram of one end of the ceiling base material. The conventional ceiling underlayment materials 50 are arranged in multiple rows perpendicular to the floor joists 40, 40, ... which are installed approximately in parallel, and ceiling panels are screwed to the second fixing portions 50t (Figure 6), which are the bottom surfaces of these ceiling underlayment materials 50.

[0008] As can be seen from Figure 6, the ceiling base material 50 consisting of the metal frame is attached to beams 41, etc. by wooden pieces 42 made by cutting long pieces of wood to an appropriate size, and both ends of the ceiling base material 50 are fixed to the wooden pieces 42 of the specified size with screws, etc. Even when both ends were fixed, the ceiling base material 50 was screwed to the wooden piece 42 only at one side edge of the first fixing portion 50d in a cantilever manner.

[0009] Therefore, the first objective of the present invention is to make it possible to easily attach and secure the ends of the metal ceiling underlayment material using metal fittings, rather than using wood.

[0010] Furthermore, the objective of the present invention is to make it easy to position the ceiling base material for installation, to provide a temporary placement or fastening effect for the ceiling base material, to make installation and fixing easy, and to manufacture the hardware itself, thereby improving the ease of manufacturing the hardware itself, and the ease of handling and workability of the hardware. [Means for solving the problem]

[0011] In order to solve the above problems, the first aspect of the present invention is an end support fitting for supporting an end of a ceiling underlayment material, the end support fitting comprising a fixed frame portion made of a long metal frame body, one longitudinal side edge of the frame body being fixed to a floor joist on an upper floor, an upright portion standing upright downward from the fixed frame portion, a ceiling board fixing portion extending from the upright portion in a substantially horizontal direction, and a bent portion bending upward from the ceiling board fixing portion in the direction of the floor joist, This end support fitting comprises a mounting portion that is placed on the upper surface of the beam portion, a back portion that is bent downward at a substantially right angle from the mounting portion, side portions that are disposed on both sides of the back portion, and a ceiling underlayment mounting portion on which the ceiling fixing portion of the ceiling underlayment is placed, When the mounting portion is placed on the beam portion, the rear surface portion comes into contact with the side surface of the beam portion, and a screw hole for fixing is provided in a lower portion of the rear surface portion, This results in an end support bracket for a ceiling underlayment, characterized in that the ceiling fixing portion of the ceiling underlayment is clamped and held by the lower edge portions of both side portions and the ceiling underlayment mounting portion.

[0012] The second aspect of the present invention is an end support bracket for a ceiling underlayment, characterized in that, in the first invention above, the angle formed between the upper surface of the ceiling underlayment mounting portion and the back surface portion is less than 90 degrees.

[0013] The third aspect of the present invention is an end support bracket for a ceiling underlayment, characterized in that, in the first or second invention above, the ceiling underlayment material mounting portion is formed by cutting and raising the central part of the back portion toward the front in an approximately rectangular shape.

[0014] The fourth aspect of the present invention is an end support fitting for a ceiling underlayment, characterized in that, in each of the first to third inventions above, the two side portions are formed by bending both side portions of the back portion toward the front.

[0015] A fifth aspect of the present invention is an end support fitting for a ceiling underlayment, characterized in that in the fourth aspect described above, one or more reinforcing ribs are provided at the bent portions of both side surfaces.

[0016] A sixth aspect of the present invention is an end support fitting for a ceiling underlayment, characterized in that in each of the above inventions, a positioning notch or marking is provided in the center of the placement portion. Effect of the Invention

[0017] In the first aspect of the present invention, it is easily possible to clamp and hold the ceiling panel fixing portion of the ceiling underlayment between the lower edges of both side edges of the end support bracket and the ceiling underlayment mounting portion. In other words, both ends of the ceiling underlayment can be clamped and temporarily placed. Thereafter, the fixing frame portion of the ceiling base material can be easily screwed to the multiple floor joists in sequence.

[0018] In addition, with this end support bracket, the entire ceiling panel fixing portion of the ceiling underlayment can be supported from below by the ceiling underlayment mounting portion, so that, unlike the floor joist fixing portion which fixes the ceiling underlayment in a cantilever manner, no rotational moment force is applied due to the cantilever support.

[0019] In the second invention, the angle between the upper surface of the ceiling underlayment mounting portion and the back portion is made less than 90 degrees, so that the front edge of the ceiling underlayment mounting portion is positioned higher than the lower edges of both side edges of the support bracket, thereby making the clamping between the two more solid and improving the temporary placement or temporary fastening effect.

[0020] In the third aspect of the present invention, the manufacturing method of the present metal fitting is made easier, and the ceiling base material mounting portion is formed by cutting and raising the center portion of the back portion toward the front in a substantially rectangular shape. It is.

[0021] In the fourth aspect of the present invention, like the third aspect, the manufacturing method of the metal fitting is made easier, and the side portions are formed by bending both side portions of the back portion toward the front.

[0022] In the fifth aspect of the present invention, one or more reinforcing ribs are provided at the bent portions of both side surfaces of the metal fitting to improve the strength of the bent portions. It is.

[0023] In the sixth aspect of the present invention, a positioning notch or engraving is provided in the center of the mounting portion of the metal fitting, and this notch or engraving makes it easy to determine the installation position of the ceiling underlayment material.

[Figure 6] FIG. 13 is an enlarged explanatory diagram of one end portion of a conventional ceiling underlayment material. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 illustrates one embodiment of an end support bracket for a ceiling underlayment according to the present invention, where (A) is a plan view, (B) is a left side view, (C) is an oblique view, and (D) is a front view.

[0026] The end support fitting 10 according to the present invention (hereinafter also simply referred to as "support fitting") is manufactured by cutting a metal plate material and appropriately performing press working. This support bracket 10 is composed of a mounting portion 11 located at its upper end, a back portion 12 bent downward at approximately a right angle to this mounting portion 11, side portions 13, 13 bent toward the front on both sides of this back portion 12 at approximately a right angle, and a ceiling underlayment mounting portion 14 formed by cutting approximately the center of the back portion 12 toward the front in a rectangular shape.

[0027] A screw hole 15 is drilled in the center of the lower part of the back part 12 for inserting a screw therethrough. Reinforcing ribs 13r, 13r are provided at the bent portions of both side portions 13, 13 and the back portion 12. Further, the placement portion 11 has a positioning notch 11k at the center of the side edge thereof.

[0028] The angle between the upper surface of the ceiling board mounting portion 14 and the back surface portion 12 is less than 90 degrees; that is, as can be seen from Figure 1(B), the tip portion of the ceiling board mounting portion 14 (the right end portion in the figure) is formed so as to be slightly inclined upward. The ceiling fixing portion of the ceiling base material is clamped between the lower edges of both side portions 13 and the ceiling base material mounting portion 14, and is therefore firmly clamped by the above-mentioned configuration. The ceiling fixing part of the ceiling underlayment is clamped at the part indicated by arrow Y in Figure 1(B).

[0029] The end support bracket 10 having the above configuration can support the end of the ceiling underlayment material at the beam portion, as shown in Figure 2 in the next figure.

[0030] FIG. 2 is an explanatory diagram showing a state in which an end portion of a ceiling underlayment is supported by the support fitting according to the embodiment. As can be clearly seen from this figure, the support bracket 10 according to the present invention is capable of supporting the end of the ceiling base material 50 with the beam portion 41 .

[0031] In other words, the mounting portion 11 of this support bracket 10 is placed on the upper surface of the corner of the beam portion 41, and its back portion 12 is joined to the front surface of the corner of the beam portion, and it can be fixed to the beam portion 41 with a screw using the screw hole 15 provided in the lower part of the back portion 12.

[0032] Since the mounting portion 11 of the support bracket 10 is provided with a positioning notch 11k, the mounting position of the support bracket 10 can be marked in advance, and the support bracket 10 can be attached and fixed in the specified position by aligning the notch 11k with the marked position.

[0033] From FIG. 2, the configuration of the ceiling underlayment material 50 supported by the support bracket 10 according to the present invention can be clearly seen. As already mentioned, the ceiling underlayment material 50 is formed from a metal frame and has a first fixed plate portion (fixed frame portion 50d) that is fixed to the floor joists by screws through the screw holes 50r, a second fixed plate portion (ceiling board fixing portion 50t) that is formed approximately parallel to the first fixed plate portion (fixed frame portion 50d) and to which the ceiling board is fixed by screws, a connecting plate portion (upright portion 50k) that connects one end of the first fixed plate portion (fixed frame portion 50d) and the second fixed plate portion (ceiling board fixing portion 50t), and a rising portion (bent portion 50s) that rises from the other end of the second fixed plate portion (ceiling board fixing portion 50t) toward the floor joist, and the rising portion (bent portion 50s) extends to a position close to the floor joist.

[0034] In the above configuration, the presence of the bent portion 50s allows the upper edge of the bent portion 50s to abut against the floor joist, thereby suppressing the clockwise rotation moment force of the ceiling board fixing portion 50t in FIG.

[0035] On the other hand, in the end support bracket 10 of the above embodiment, the clamping between the lower edge portions of the side portions 13, 13 on both sides and the ceiling base material mounting portion 14 makes it possible to almost completely resist the above-mentioned rotational moment force.

[0036] FIG. 3 is an enlarged explanatory view showing the opposite end of the embodiment shown in FIG. 2 as viewed from above. The diagram shown in FIG. 3 shows a state in which a ceiling board 60 is fastened from below to the underside of a ceiling board fixing portion 50t of the ceiling base material 50 by screws 60r.

[0037] In this way, the end of the ceiling board fixing portion 50t of the ceiling base material 50 is clamped and held on both sides by the lower edges of the side portions 13, 13 on both sides of the end fixing bracket 10 and the ceiling board mounting portion 14.

[0038] FIG. 4 is an explanatory diagram showing the assembled state of the end support fitting and the ceiling base material according to the above embodiment. As can be clearly seen from this figure, the ceiling fixing portion 50t of the ceiling base material 50 is clamped and held between the side portions 13, 13 on both sides of the end support bracket 10 and the ceiling base material mounting portion 14.

[0039] At the lower portion of the back surface portion 12 of the end support bracket 10, the support bracket 10 is screwed to the beam portion 41 by a screw 15r. In this way, the ceiling base material 50 is clamped and held at both ends by the support fittings 10, 10, and then the fixing frame portion 50d of the ceiling base material 50 is screwed to the floor joists in sequence.

[0040] Although one embodiment of the present invention has been described above, the present invention can be modified in various ways as described below.

[0041] First, the size of the support bracket and the size of each part can be appropriately changed as needed. In the above embodiment, the shape of the ceiling underlayment material mounting portion is also approximately rectangular, but this is because the back portion is cut and raised, but it can also be a different shape. However, because it is necessary to increase the support area of ​​this ceiling underlayment material, a rectangular shape is optimal, and this shape is also optimal when the cutting and forming processes are taken into consideration.

[0042] In the above embodiment, the side surfaces on both sides are also formed in a trapezoidal shape when viewed from the side, but the shape may also be substantially rectangular or may be another shape. In the above embodiment, a notch is provided in the center of the side edge of the mounting portion, but this notch may be omitted and an imprint may be formed in the center of the mounting portion instead.

[0043] As described above, the present invention provides an end support bracket with a simple structure that can be easily manufactured from metal plate material by cutting and pressing, and that can properly clamp and hold both ends of a cantilever-type ceiling underlayment material.
