Description

[Detailed description of the invention] [Industrial field of application] The present invention is useful, for example, in prefabricated houses, where a field edge support for mounting a ceiling panel is suspended from an H-shaped steel cross beam. The present invention relates to metal fittings used when supporting various members with horizontal flanged frame members in buildings.

[Conventional technology]

Generally, the ceiling in a prefabricated house is constructed by attaching a mounting bracket 21 to the horizontal flange 20a of a horizontal beam 20 made of H-shaped steel, and attaching a bottle 23 to the mounting bracket 21 with a nut 29, as shown in FIG. The receiver 22 is suspended, the field edge 25 is fixed to the field edge receiver 22 via the connecting fittings 24, and the field edge 25 is fixed.
It has a structure in which a ceiling plate or ceiling panel 26 is stretched on the lower surface of the ceiling.

In this case, the mounting bracket 21 for suspending the field edge support 22 on the cross beam 20 is
Conventionally, the configuration was as shown in FIG.

That is, this conventional mounting bracket 21 is formed of a metal plate and has a downward U-shaped cross section, and a bottle is inserted into the upper surface plate of one end of the mounting bracket 21 that protrudes outside the free end of the horizontal flange 20a. While a general-purpose through hole 27 is bored in the left and right side plates 21a, 21a at the other end, the left and right side plates 21a, 21a are provided at the other end.
The left and right side plates 21a, 21a are fitted to the horizontal flange 20a by cutting out and forming an engaging groove 28 opened on the other end surface so as to extend horizontally. The horizontal flange 20a can be attached to two types of cross beams 20 with different thicknesses by forming the groove width in two stages, wide at the opening and narrow at the back. It was hot.

[The problem that the idea aims to solve]

However, this conventional mounting bracket 21 can only be attached to two types of cross beams 20 whose horizontal flanges 20a have different thicknesses.
If there are three or more thicknesses of 0a, the engagement groove 2
In addition to the problem of having to create multiple types of 8 with different groove widths, which requires time and effort to manage the mounting brackets 21, there are also issues with mounting workability and mounting strength, as described below. There were also problems in this regard.

That is, since the groove width of the engagement groove 28 is constant to a preset dimension, if the groove width of the engagement groove 28 is even slightly smaller than the wall thickness of the horizontal flange 20a, the mounting bracket 21 must be installed by hitting it with a hammer. If the width of the engagement groove 28 is even slightly larger than the wall thickness of the horizontal flange 20a, The mounting fittings 21 would shift or fall off, reducing the strength of the mounting.

In particular, when the width of the engagement groove 28 is formed in two stages, wide and narrow, if the thickness of the horizontal flange 20a is thick, the mounting bracket 21 has a dimension that is half the depth of the engagement groove 28 relative to the horizontal flange 20a. As a result, the mounting bracket 22 is likely to fall off, and the distance between the through hole 27 of the mounting bracket 21 and the free line of the horizontal flange 20a increases, resulting in an increase in the moment acting on the mounting bracket 21. Therefore, the support strength for the field edge support 22 was significantly reduced.

The object of the present invention is to provide a mounting bracket that eliminates these problems.

[Means to solve the problem]

In order to achieve this object, the present invention provides a fitting body which is disposed on the upper surface of a horizontal flange of a bone member of a building, and a mounting portion for a member supported by the bone member, and a mounting portion on the upper surface of the horizontal flange. A pair of left and right side plates that come into contact are provided so as to extend in a direction that intersects the end surface of the free edge of the horizontal flange in a plan view, and the metal fitting body is further provided with a side plate of the horizontal flange at a lower portion of the metal fitting body. A clamping piece made of an elastic plate that is in contact with the lower surface is integrally provided so as to extend from the free end of the horizontal flange toward the root, and the clamping piece is attached to both left and right sides of the horizontal flange. The vertical gap with the plate is formed in an inclined shape so that it becomes narrower toward the free end of the clamping piece.

[Functions and effects of the idea]

With this configuration, the mounting bracket is placed in a position such that the ends of the left and right side plates and the free end (tip) of the clamping piece touch the free end edge of the horizontal flange on the bone member, and in that state, the mounting bracket is installed. , to attach the mounting bracket to the horizontal flange of the bone member by pushing it in the direction of the base of the horizontal flange against the elasticity of the clamping piece and holding the horizontal flange of the bone member from above and below between the left and right side plates and the clamping piece. In this state, by attaching various members to the attachment portion of the fitting body, various members can be supported by the bone member via the attachment fitting.

In this case, since the clamping piece is formed in an inclined shape such that the vertical gap between the clamping piece and the left and right side plates narrows toward the free end of the clamping piece, the thickness of the horizontal flange is the same as that between the clamping piece and the left and right side plates. The horizontal flange can be elastically held between the left and right side plates and the holding piece if the vertical gap is between the minimum and maximum dimensions of Even if there is an error in the processing of the horizontal flange or mounting bracket, the difference in the thickness of the horizontal flange and the processing error can be absorbed by changing the amount of flexural deformation of the clamping piece. 1
Different types of fittings can be attached to different sizes of bone members with different horizontal flange thicknesses.

Moreover, since the horizontal flange of the frame member is held in three-point contact between the two side plates that contact the upper surface and the clamping piece that contacts the lower surface, the mounting bracket can be mounted without any play. Can be installed in a stable condition.

Therefore, according to the present invention, the mounting bracket can be stably attached to the horizontal flange of the bone member without wobbling by a one-touch operation of pushing the mounting bracket into the horizontal flange of the bone member. , it is possible to efficiently attach various components to the frame members of a building via the mounting brackets, and even if the thickness of the horizontal flange is different, it is possible to support various components with one type of mounting bracket. This has the effect of reducing the effort required to manage the mounting fittings.

[Example] Next, an example of the present invention is shown in the drawings (Figs. 1 to 4).
The explanation will be based on Figure).

In the figure, reference numeral 1 denotes a metal fitting body 2 disposed on the upper surface of the horizontal flange 9a of the cross beam 9.
The fitting main body 2 of the fitting 1 extends substantially perpendicularly to the end surface of the free edge of the horizontal flange 9a in plan view, and comes into contact with the upper surface of the horizontal flange 9a. The metal fitting main body 2 has two side plates 2a, 2a, and is formed into a U-shaped cross section with a downward opening. , Nut 3 is an example of the mounting part.
is caulked to be unrotatable or rotatable, and the field edge receiver 11 is attached via the bolt 10 screwed into the nut 3.
I try to suspend it.

Reference numeral 4 denotes a clamping piece 4 made of an elastic plate attached to the left and right side plates 2a of the metal fitting main body 2, and the clamping piece 4 is formed in a U-shape in side view, opening toward the base of the horizontal flange 9a. A locking piece 5, which protrudes laterally from the tip of a mounting piece 4b connected to the upper end of the vertical portion 4a, is inserted into an engagement groove 6 cut out in the side plate 2a of the metal fitting body 2, and other parts of the metal fitting body 2 A stopper piece 7 is inserted from the end direction and is cut and raised diagonally inward on the side plate 2a of the metal fitting main body 2.
By abutting the inner surface of the vertical portion 4a, the vertical portion 4a is attached to the fitting main body 2 in a manner that it cannot be removed.

By forming the holding piece 4 in an inclined shape so that the vertical gap between the holding piece 4 and the left and right side plates 2a, 2a narrows toward the free end of the holding piece 4, the left and right side plates 2a, The horizontal flange 9a can be held between the holding piece 2a and the holding piece 4.

Note that a diagonally downward guide portion 4c is formed at the free end (tip) of the clamping piece 4 to facilitate pushing in the horizontal flange 9a. In the middle between
An auxiliary clamping piece 8 is cut and raised to extend obliquely upward toward the vertical portion 4a.

In this configuration, the mounting bracket 1 is arranged such that the ends of the left and right side plates 2a, 2a and the clamping piece 4 are in contact with the free edge of the horizontal flange 9a, and in this state, the mounting bracket 1 is attached to the horizontal flange 9a. When pushed toward the base, both side plates 2a of the metal fitting main body 2
The horizontal flange 9a is held between the holding piece 4 and the holding piece 4,
The metal fitting 1 is attached to the horizontal flange 9a.

Then, screw the bolt 10 into the nut 3 of the mounting bracket 1 from below after installation, fix the field edge receiver 11 to this bolt 10 with the nut pair 12, and attach the connecting member 13 to the field edge receiver 11. A ceiling can be formed by fixing the field edge 14 via the field edge 14 and stretching the ceiling panel 15 on the lower surface of the field edge 14.

In this way, since the mounting bracket 1 is attached to the horizontal flange 9a of the cross beam 9 by using the elasticity of the clamping piece 4, the mounting bracket 1 can be installed in a one-touch operation by simply pushing it into the horizontal flange 9a. In addition, the pair of left and right side plates 2a, 2a are in contact with the upper surface of the horizontal flange 9a, and the clamping pieces 4 are in contact with the lower surface of the horizontal flange 9a, respectively.
Since the horizontal flange 9a is held in a three-point contact state, the mounting bracket 1 can be mounted in a stable state without wobbling.

In addition, since the clamping piece 4 is formed so that the vertical gap between it and the both side plates 2a narrows as it approaches the free end, even if the horizontal flanges 9a have different thicknesses, one type of metal fitting main body 2 can be used. Therefore, we can respond accordingly.

In addition, as in the embodiment, the auxiliary clamping piece 8 is attached to the clamping piece 4.
By cutting and raising the horizontal flange 9a,
Since the lower surface of the metal fitting body 2 can be pressed at two places, the attachment strength of the metal fitting main body 2 to the horizontal flange 9a can be further improved.

Note that the means for attaching the clamping piece 4 to the fitting body 2 is not limited to the embodiment, and for example, a single metal plate may be processed into a sheet metal without forming the fitting body 2 and the clamping piece 4 as separate members. Accordingly, the clamping piece 4 may be formed integrally connected to the metal fitting main body 2. Also, nut 3 is used as the mounting part.
In this case, the nut 3 may be attached to the lower surface of the upper plate of the metal fitting body 2.
