Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing device for fixing a cable rack horizontally suspended on a beam or other supporting material of a building to the supporting material.

In the conventional cable rack, for example, as shown in Fig. 1, a metal fitting C is engaged with the main girder a of the cable rack at the hook piece at the upper end, and a bolt f and a nut g are attached to the supporting member e at the base piece d at the lower end. Generally, the bolts are tied together and fixed to the support material e, but with this method, drilling at a high place in order to form the insertion hole for the bolt f in the support material e requires work and is dangerous. Moreover, the strength of the supporting material e is reduced due to the holes.

The purpose of the present invention is to provide a metal fitting that eliminates such inconveniences, and the upper end of the metal fitting engages with the main girder 3 of a cable rack 2 horizontally suspended on a beam or other supporting material 1 of a building. A locking metal fitting 6 having a hook L14, a base piece 5 at a lower end facing the upper surface of the support member 1 and extending in the longitudinal direction thereof, and a locking member 6 that sandwiches the base 145 and the support member 1 and is perpendicular to the longitudinal direction. It consists of a substantially U-shaped fastening fitting 9 with upper and lower receiving pieces 7, 8 extending from one side to the other in the direction of a locking piece 11 that engages with the outer edge in the longitudinal direction of the upper receiving piece 7 at the tip of the upper receiving piece 7; and a locking piece that engages with the other side surface of the support member 1 at the tip of the upper receiving piece 7. 12, respectively.

The cable rack 2 includes, for example, a beam member made of a long angle member in the front-back direction as shown in FIGS. 2 and 3, and a supporting member 1.
The fixation is first made by engaging the hook piece 4 at the upper end of the locking metal fitting 6 with the main girder 3, and then by connecting the base piece 5 at the lower end of the locking metal fitting 6 with the support piece 5. This is done by sandwiching between the upper and lower receiving pieces 7 and 8 of the fastening fitting 9 to which the material 1 is inserted from the right side, and pressing the locking screw 10 screwed into the lower receiving piece 7 onto the lower surface of the supporting material 1. .

At this time, the fastening metal fitting 9 has a locking piece 11 at the tip of the base piece 5 that engages with the outer edge of the upper receiver piece 7 in the front-rear direction, and a tip end of the upper receiver piece 7 that engages with the left side surface of the support member 1. The main girder 3 is firmly fixed to the support material 1 through the fastening metal fittings 9 and the fastening metal fittings 6. .

It is also possible to configure the locking metal fitting 6 and the fastening metal fitting 9 in one piece, but in this case, it can only be applied to the support member 1 of a certain width due to the formation position of the locking piece 12. On the other hand, when the fastening metal fittings 9 are prepared separately, only the fastening metal fittings 9 can be replaced and the support material 1 can be applied to various supporting materials 1 such as existing beam materials whose widths are not constant.

In this way, according to the present invention, the locking metal fitting 6 and the fastening metal fitting 9
The cable rack 2 can be firmly fixed to the support member 1 by using the screws 10 and the fixing screws 10 without drilling holes in the support member 1, and the above-mentioned disadvantages of the conventional method can be reliably solved. It has advantages such as being able to be applied to the support material 1.
