Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting bracket capable of easily, quickly and firmly attaching a receiving bracket to a structural material such as a cross beam without welding.

[Conventional technology and its problems]

Conventionally, there are various shapes and structures of brackets for mounting folded plate-like construction boards, but at present, most of them are welded to mount the brackets to structural materials such as horizontal beams. It is stuck. The welding work involved many work steps. That is, there is required a work procedure in which a welding machine is set at the site, an actual welding operation is performed, slag is removed from the welded portion, and then a rust preventive paint is applied thereto. The welding work cannot be performed because the welding strength is not sufficient when the temperature is below 0 degrees Celsius or there is wind, and there is the inconvenience that the work cannot be performed on rainy days because of the danger of electric shock. It was Further, there is a drawback that a certain strength cannot be secured due to the difference in skill of welding operators. Further, simply by fixing work such as bolts and nuts, any worker can fix the work with a certain mounting strength, but in a long-term use, there was a big defect that the work loosened due to vibration and the like and came off.

Under these circumstances, there is a demand for a metal fitting and a metal fitting mounting member that can be easily and quickly mounted and that is strong and does not come off.

[Effect of device]

In the invention of claim 1, a metal fitting body A having concave engaged portions 2 formed at both ends of the metal fitting main plate 1, and the concave engaged portion 2
A clip B in which a pressing locking portion 4 which can be locked only from the width direction of the metal fitting main plate 1 is formed at the tip of the elastic U-shaped bending portion 3
Firstly, the receiving metal fitting C can be simply and quickly attached to the structural member 8 without welding, and secondly, when the clip B is attached, it is relatively weak. It is possible to achieve such an effect that the fixing force of the clip B is not deteriorated even after the attachment.

To describe these effects in detail, first, the metal fitting main plate 1 of the metal fitting body A is placed on the bottom portion 7 of the receiving metal fitting C from above, and the mounting surface 8a of the structural member 8 is attached. Bracket main plate 1 and mounting surface 8a
The metal fitting C can be fixed to the structural member 8 by sandwiching and with the pressure locking portion 4 of the clip B made of another material. Therefore, in conventional welding work, this work process has many
Specifically, there is a need for work procedures such as setting a welding machine at the site, performing actual welding work, then dropping the slag at the welding location, and applying rust-preventive paint to it. The work cannot be done when the temperature is below 0 degree Celsius or when there is wind, because the welding strength is not sufficient, and on rainy days there is the inconvenience that the work cannot be done due to the danger of electric shock. In the present invention, regardless of such weather conditions, this mounting work is performed by placing the metal fitting main plate 1 on the mounting surface 8a at the bottom 7 position of the location where the receiving metal fitting C is provided, and sliding the clip B appropriately. It can be easily installed by only stopping it, and solves the above-mentioned drawbacks. Furthermore, unlike construction by means of fixing with fixing tools such as bolts and nuts,
It is only that the clip B is placed and inserted and locked, and in practice, it can be performed almost instantly.

In particular, when the mounting metal fitting of the present invention is used, if the chevron portion 6 and the bottom portion 7 are present, the conventionally known receiving metal fitting C can be used and can be provided at a lower cost. .

Next, at both ends of the metal fitting main plate 1 of the metal fitting body A, there are concave engaged parts.
2 and 2 are formed, and when the metal plate main plate 1 and the mounting surface 8a of the structural member 8 are clamped by the clip B, the press locking portion 4
Is locked to the concave locked portion 2, and since the locking structure is a concave locking, the clip B hardly comes off easily, and the pressing locking portion 4 and the pressing edge are Holds a predetermined gripping force at the elastic U-shaped bent portion 3, and the mounting strength between the concave locked portion 2 and the mounting surface 8a becomes constant, whichever worker does this. This can be realized, and it is possible to always secure a certain mounting accuracy.

Particularly, although the clip B of the present invention is first attached to the structural member 8, it is opened only by the plate thickness of the mounting surface 8a of the structural member 8, and then the clip B is connected to the concave locked portion 2 and the plate thickness. Only the portion is opened, and the pressing engagement portion 4 is engaged with the concave engagement portion 2. Since the amount of deformation is small at the time of mounting in this way, the clip B does not exceed the elastic limit and is not distorted. Has a great effect of being able to be attached to the mounting surface 8a of the structural member 8.

Further, since the pressing engagement portion 4 is engageable with the concave engagement portion 2 only in the width direction of the metal fitting main plate 1, the pressing engagement portion 4 is engaged with the recess engagement portion 2. Therefore, the locking structure is
Due to the concave locking, the clip B hardly drops out (direction orthogonal to the longitudinal direction of the structural member 8) easily, and the pressing locking portion 4 and the pressing portion 4'are made of elastic elastic material. Since the predetermined bending force is held by the character-shaped bent portion 3, the mounting strength between the concave locked portion 2 and the mounting surface 8a becomes constant, which can be realized by any worker. Therefore, there is an advantage that a constant mounting accuracy can always be secured.

Further, in the invention of claim 2, a metal fitting body A in which a concave engagement portion 2 is formed at one end of the metal fitting main plate 1 and a sandwiching bent portion 5 is formed from the other end, and the concave engagement portion. In FIG. 2, the receiving metal fitting C is made of a structural material by using the press fitting portion 4 that can be locked only in the width direction of the metal fitting main plate 1 as the mounting fitting made of the clip B formed at the tip of the elastic U-shaped bent portion. The number of clips B can be reduced by attaching the clip B from one end of the structural material 8 when attaching the clip B to the structure 8.

Particularly, in the mounting bracket of the present invention, one is clamped and fixed by the clamping and bending portion 5, and the other is fixed by the clip B. Not only can the configuration be simplified, but also the mounting construction can be performed more easily and quickly. There is an advantage that can be.

Other configurations are the same as those of the invention of claim 1, and the same effect as this can be exhibited.

In addition, if the spread edge 4a is formed on at least one end in the longitudinal direction of the pressing and locking portion 4, the clip B is inserted into the concave locked portion 2 and
It has the advantage that it is extremely easy to polymerize and easy to mount.
