Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a bracket that can be easily and quickly and firmly mounted on a structural material such as a cross beam.

[0002]

[Prior Art]

 Conventionally, there are various shapes and structures of brackets for mounting folded plate-like construction boards. Currently, most of the brackets are attached by welding to structural members such as horizontal beams. It is stuck. The welding work involved many work steps.

[0003]

[Problems to be solved by the device]

 In the above work, it is necessary to set up a welding machine at the site, perform the actual welding work, then remove the slag at the welding location and apply rust-preventive paint to the work procedure. The 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 due to the danger of electric shock on rainy days. ..

Further, there is a drawback that a certain strength cannot be ensured due to the difference in skill of welding workers. In addition, simply fixing the bolts and nuts can be fixed to any worker with a certain level of attachment strength, but with long-term use, there was a major defect that they could come loose due to vibrations and the like.

Under these circumstances, there is a demand for a receiving metal fitting that can be easily and quickly attached, firmly, and securely.

[0006]

[Means for Solving the Problems]

 Therefore, the present invention has been earnestly studied in order to solve the above-mentioned problems, and as a result, the present invention has been proposed in which two leg pieces having a restoring property are provided from both ends of the top surface in the width direction, and the leg pieces are placed inward from the lower ends of the both leg pieces. It consists of a bracket main body with a stop, and a structural material with a locking through-hole in which the locking part can be inserted and locked on the side surface facing each other in the width direction. With the mounting structure of the receiving metal fittings that can be locked, it is possible to easily, quickly and firmly attach to the structural material without using fasteners such as bolts and nuts. It is a thing.

[Effect of the device]

 According to the first aspect of the present invention, both leg pieces 1b, 1b having a restoring property are provided from both ends in the width direction of the top surface 1a, and the locking portions 2, 2 are formed inward from the lower ends of the leg pieces 1b, 1b. It is composed of a bracket main body A and a structural member B having locking through holes 8 and 8 into which the locking portions 2 and 2 can be inserted and locked in side surface parts 7b and 7b facing each other in the width direction. Due to the mounting structure of the receiving metal fitting capable of locking the locking portions 2 and 2 in the through holes 8 for use, first of all, it can be easily and quickly attached to the structural member B such as a cross beam. Secondly, regardless of the skill level, any worker can always fix the bracket to the structural material B with a constant strength, and thirdly, the structure of the bracket main body A and the structural material B. Is extremely simple, and each has the effect that it can be provided at a low price.

To describe these effects in detail, first, the engaging portions 2 and 2 formed at the lower ends of both leg pieces 1b and 1b of the receiving metal body A are formed on both side surface portions in the width direction of the structural material B such as lip channel steel. 7b, 7b are inserted and locked in the locking through holes 8, 8 to fix the bracket main body A to the structural member B. The work is simply performed on both legs as shown in FIG. This is a process of inserting the locking portions 2 and 2 into the locking through holes 8 while slightly expanding the pieces 1b and 1b, which is extremely short and easy. Moreover, since the two leg pieces 1b, 1b have a restoring property, even if the two leg pieces 1b, 1b are expanded, the restoring force of the two side surface portions 7b, 7b of the structural member B causes an appropriate force. There is also an advantage that the restoring force acts to prevent the slipping out by pressing with.

In conventional welding work, there are many work steps. Specifically, a welding machine is set on the spot, actual welding work is performed, and then slag is dropped at the welded portion to prevent rust. It is not possible to work because there is a need for work procedures such as applying paint, welding work at temperatures below 0 degrees Celsius, or in the presence of wind. Although there was the inconvenience of not being able to work due to the danger of electric shock, etc., the present invention can be constructed regardless of such weather conditions and can solve the above-mentioned drawbacks.

Further, unlike the means of fixing with fixing tools such as bolts and nuts, the work of fixing the locking portions 2 and 2 to the structural material B can be done instantly, which is a quick and simple work, and welding There is no difference in the finish depending on the skill of each worker unlike the fixing means, and it is possible to always secure a constant mounting strength regardless of which worker works.

Next, in claim 2, both leg pieces 1b, 1b having a restoring property are provided from both ends in the width direction of the top surface 1a, and the locking portions 2, 2 are provided inward from the lower ends of the leg pieces 1b, 1b. And a structural member B in which side walls 7b, 7b facing each other in the width direction are formed with through holes 8 for locking into which the locking portions 2, 2 can be inserted and locked. The leg portions 1b, 1b are formed by a fastening ring body 9 capable of engaging the engaging portions 2, 2 in the engaging through-holes 8, 8 and tightening the leg members 1b, 1b inward. Has a structure for mounting a metal fitting that can be pressed against both side portions 7b, 7b of the structural material B, so that after the main body A of the metal fitting is mounted on the structural material B, the tightening / combining frame pieces 9a, 9a By installing the two leg pieces 1b, 1b of the receiving metal body A so as to press them inward, the both leg pieces 1b, 1b can be spread over a predetermined width or more. As a result, the distance between the locking portions 2 and 2 does not increase, and it is possible to prevent the locking portions 2 and 2 from coming off the locking through holes 8 and 8 and secure the fixing. can do.
