Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is, for example, in a prefabricated house, a field frame receiver to which a field frame member for mounting a ceiling panel is mounted is hung on a horizontal beam with a lip having a C-shaped cross section. The present invention relates to a mounting bracket used for mounting another member to a ribbed bone member in a building such as a case of mounting via a bolt.

[Conventional technology]

As a metal fitting for attaching a field rim receiver to a horizontal beam with a C-shaped cross-section in a building, as a prior art, Shokai 62
As shown in FIG. 9, the Japanese Patent No. 80913 discloses a pair of left and right side plates 4 opposed to a metal fitting body 3 in which a bolt hole 2 for a hanging bolt A for a field support (not shown) is supported. The metal fitting 1 has been proposed in which the narrow width engagement groove 5 to be fitted to the upward lip b of the lateral beam B is cut out and formed on each of the left and right side plates 4 respectively.

The symbol C is a nut for fixing the suspension bolt A.

[Problems to be solved by the device]

However, this conventional metal fitting 1 can be attached to the lip b with one touch by making the groove width dimension of the engaging groove 5 larger than the plate thickness dimension of the lip b. When the hanging bolt A is inserted into the bolt hole 2 from below after the mounting of the fitting or when the hanging edge A is attached to the hanging bolt A mounted on the metal fitting body 3, when the upward force acts on the fitting 1, the fitting 1 lip b It had the drawback that it could easily come off.

On the other hand, it is conceivable that the engaging groove 5 is fitted into the lip b by hitting with a hammer so that the groove width dimension of the engaging groove 5 is slightly smaller than the plate thickness dimension of the lip b. However, in this way, even though the metal fitting 1 can be firmly attached, there is a problem that the mounting work becomes complicated and it becomes difficult to change the mounting position of the metal fitting 1. However, there is a problem in that the ease of attaching the metal fitting 1 and the function of preventing the metal fitting 1 conflict with each other.

The present invention aims to solve this problem.

[Means for Solving the Problems]

In order to achieve this object, in the present invention, a pair of left and right side plates are provided so as to oppose each other on a metal fitting body having a mounting portion for a member supported by a lip-supported bone member in a building, and each of the left and right side plates is A mounting metal fitting formed by cutting open a narrow-width engagement groove to be fitted into the lip of the bone member, wherein the metal fitting body has an elasticity extending toward the open end of the engagement groove between the left and right side plates. The plate is fixed, and the engaging portion for the bone member is bent and formed at the tip of the elastic body.

[Function and effect of device]

In this structure, the engaging portion at the tip of the elastic plate is brought into contact with the outer surface of the lip of the bone member, and the engagement grooves of the left and right side plates are fitted to the lip of the bone member while resisting the elasticity of the elastic plate. By doing so, the metal fitting can be attached to the lip of the bone member with one touch.

Then, when the metal fitting is attached to the lip of the bone member, the elastic plate restores its original posture by its elastic force,
Since the locking portion formed by bending at the tip of the elastic plate contacts the outer surface of the portion of the bone member connected to the lip, the metal fitting is held in a state in which it cannot be removed from the lip.

Therefore, according to the present invention, the metal fitting can be attached to the lip of the bone member with one touch, and the metal fitting can be reliably prevented from falling off the lip of the bone member.
There is an effect that the work of attaching another member to the bone member via the metal fitting can be efficiently performed.

Moreover, since the elastic plate is disposed in the region sandwiched by the left and right side plates, and the elastic plate is protected by the left and right side plates, it is possible that the elastic plate does not touch and deform other objects during transportation. In addition to being able to prevent it, the elastic plate does not get in the way, so that it can be easily handled.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 6). In the drawings, reference numeral 10 indicates a horizontal mounting portion 11a to which a nut C is fixedly attached to a hanging bolt A. The metal fitting body 11 is provided with a metal fitting in which a pair of left and right side plates 12 are extended so as to face each other, and a horizontal beam B is provided on each of the left and right side plates 12.
Narrow engaging grooves 13 and 14 with downward openings to be fitted on the lip b of the
The front and back sides are cut open by two.

In this case, the front and rear two engaging grooves 13, 1 on the left and right side plates 12
4 has a small groove width dimension (e1) of the first engagement groove 13 located near the tip of the side plate 12, and a second groove located near the base end of the side plate 12.
The groove width dimension (e2) of the engaging groove 14 is formed to be large so that the engaging groove 14 can be attached to the two types of horizontal beams B having different plate thickness dimensions (t), and the first engaging groove 13 and The lower end of the intermediate portion 12a sandwiched between the two engaging grooves 14 is made to project downward by a dimension (1) from the lower surface of the tip portion 12b of the side plate 12.

Then, on the inner surface of the metal fitting body 11, elastic plates 16 such as plate springs extending in a substantially horizontal direction toward the front end direction of the left and right side plates 12 are fixed by rivets 17 and the like, and the front and rear midway parts of the elastic plates 16 are fixed. Is bent substantially downward to form the first engaging piece 16a extending toward the open end of the first engaging groove 13, while the first engaging piece 16a is cut and raised to form the second engaging groove. A second locking piece 16b extending toward the open end of 14 is formed, and the tips of both locking pieces 16a, 16b are in a substantially V-shaped engagement with which the lower surface of the horizontal portion b'of the cross beam B can be abutted. The stoppers 16c, 16d are formed by bending them forward.

In order to form the two locking pieces 16a, 16b, as shown in FIG. 7, each locking piece 16a, 16b is formed by a separate elastic plate 16, or in FIG. As shown, make a notch in the elastic plate 16 from the tip,

In order to attach the metal fitting 10 to the cross beam B having a small plate thickness (t) in the above configuration, as shown in FIG.
The locking portion 16c of a is brought into contact with the outer surface of the lip b of the cross beam B, and is pressed toward the cross beam B against the elasticity of the first locking piece 16a as shown by arrow D, As shown by the arrow E, the metal fitting 10 may be slid downward to fit the first engaging groove 13 of the left and right side plates 12 into the upward lip b,
When the first engaging groove 13 fits into the lip b, the first engaging piece 16
The locking portion 16c of a engages with the lower surface of the horizontal portion b'of the horizontal beam B, so that the metal fitting 10 is held upward and cannot be pulled out.

Therefore, even when an upward force is applied to the metal fitting 10 when mounting other members such as a field rim receiver to the hanging bolt A, the metal fitting 10
Does not fall off from the lip b, and the work of attaching the field rim receiver and the like can be performed quickly and reliably.

In addition, in order to attach to the horizontal beam B having a large plate thickness (t), as shown in FIG.
It suffices to fit the second engaging groove 14 of the above into the upward lip b of the transverse beam B, and as a result, as shown in FIG.
The locking piece 16d of 16b is engaged with the lower surface of the horizontal portion b'of the horizontal beam B, and the metal fitting 10 is held upward so that it cannot be pulled out.

In this case, if a plurality of engaging grooves 13 and 14 having different groove widths are formed in the left and right side plates 12 as in the embodiment, one kind of metal fitting 10 can be used to form a plurality of types having different plate thickness dimensions (t). Horizontal beam B
Of the side plate 12 and the middle part 12
When a is projected downward from the lower surface of the tip portion 12b of the side plate 12,
When attaching the metal fitting 10 to the lip b, the lower end of the intermediate portion 12a of the side plate 12 contacts the outer surface of the lip b, so that the first engaging groove 13 and the lip b can be automatically positioned. Easy to do.

When the front and rear engagement grooves 13 and 14 are formed in the side plate 12, as shown by the alternate long and short dash line in FIG. 5, the side plate 12 is located closer to the metal fitting body 11 than the second engagement groove 14. Located proximal end 12
