Japanese Unexamined Patent Publication No. 2000-27457

The reason why the angle of the connecting part with respect to the bottom is set to a sharp angle is that in the construction work in which the concrete slab is installed upright on the floor slab, this support is provided for the floor slab and the concrete slab connected by the support. Because it is arranged at a sharp angle, even if a load of tensile force or compressive force acts on the support, the support hook base tool can effectively support this load without deformation. .. However, the support is used in various applications, and in some applications, the support is not arranged at an acute angle to the two objects connected by this support, for example, 0 degrees (parallel) or 90 degrees (parallel). It may be arranged at various angles such as (right angle), or it may be arranged at different acute angles. Therefore, even if the support is used in such a usage mode, the support is supported. There is a need for a support hook base that can effectively support the load transmitted between the object and the object.

An object of the present invention is to provide a support hook base that allows a support to be arranged at various angles with respect to two objects connected by the support.

The hooking base for support according to the present invention is for hooking a hook portion provided at an end portion in the length direction of a support that is arranged between two objects and connects these objects, in order to hook the hook portion of the two objects. A support hook base tool that is fastened to at least one of the objects, and is one of a bottom portion that is fastened to the object by the fastener, a hook portion that hooks the hook portion, and one in the length direction. Since one end is connected to the bottom and the other end is connected to the hook, the bottom and the hook are connected and at an acute angle with respect to the bottom. In the support hook base tool configured including the connecting portion, a connecting portion connecting the bottom portion and the connecting portion is provided between the bottom portion and the connecting portion. It is a feature.

As described above, in the support hook base tool according to the present invention, since the connecting portion for connecting the bottom portion and the connecting portion is provided between the bottom portion and the connecting portion, two connecting portions are connected by the support. Even if this support is used in each usage mode in which this support is arranged at an acute angle or at various angles such as 0 degree and 90 degrees with respect to the object, the connecting portion having an acute angle with respect to the bottom is the object. Deformation due to the load acting between the support and the support is prevented by the above connection part, and the support of this load can be effectively performed between the support and the object, whereby the support is connected by this support. It becomes possible to use various angles with respect to the two objects to be formed.

In the above-mentioned support hook base tool according to the present invention, the connecting portion connecting the bottom portion and the connecting portion may be a rod-shaped one, or a wall-shaped one having a width dimension in the length direction of the connecting portion. In other words, it may be a wall part.

Of these, if the connecting portion that connects the bottom portion and the connecting portion is a wall portion having a width dimension in the length direction of the connecting portion, the width dimension of the connecting portion in the length direction of the wall portion means that the connecting portion is connected to the bottom portion. The connection strength with the connecting portion can be increased, so that the load can be supported more effectively between the object and the support.

Further, when the connecting portion connecting the bottom portion and the connecting portion is a wall portion having a width dimension in the length direction of the connecting portion as described above, the width dimension of this wall portion is used as the length of the connecting portion. It may be a dimension of only a part of the total length, or it may be a dimension over the entire length of the connecting portion.

Of these, if the width dimension of the wall portion is set to the dimension over the entire length of the connecting portion, the connection strength between the bottom portion and the connecting portion by the wall portion can be increased accordingly, so that the connection strength between the object and the support can be increased. The load can be supported even more effectively.

Further, in the above-mentioned support hook base tool according to the present invention, the wall portion serving as the connecting portion connecting the bottom portion and the connecting portion bulges to at least one side in the thickness direction of the wall portion. It may be provided with a reinforcing portion.

According to this, the thickness dimension of the wall portion is increased by the amount of the reinforcing portion at the place where the reinforcing portion is provided, so that the strength of the wall portion is also increased, whereby the load acting between the object and the support is increased. Can be effectively received by the wall part.

The reinforcing portion provided on the wall portion may bulge only on one side in the thickness direction of the wall portion, or may bulge on both sides in the thickness direction of the wall portion. If the reinforcing portions are provided on both sides in the thickness direction of the wall portion, the strength of the wall portion can be further increased by these reinforcing portions.

Further, in the support hooking base tool according to the present invention, the above-mentioned connecting portions may be provided on both sides of the hooking portion, and when two connecting portions are provided on both sides of the hooking portion in this way, the hooking portions are provided. The portion is provided with a recess portion that is recessed in the internal direction of the hook portion with respect to both sides of the two connecting portions, and the hook provided in the recess portion at the end portion in the length direction of the support described above. You may try to hook the part.

According to this, the hook portion is hooked on the recessed portion that is recessed in the internal direction of the hook portion with respect to both sides of the two hook portions on the connecting portion side among the hook portions provided on the support hook base tool. Therefore, the hook portion is prevented from shifting on the side of the two connecting portions with respect to the recessed portion by the stepped portions in the inward and outward directions of the hooking portions formed on both sides of the recessed portion. It can be stably hooked in the recess.

Further, in the above-mentioned support hook base tool according to the present invention, when the above-mentioned fastener for fastening the bottom to an object is a bolt, the shaft portion of the bolt is inserted into the bottom. When forming holes, a plurality of holes having different diameters may be provided at the bottom.

According to this, various bolts having different shaft diameters can be selectively used according to the thickness dimension, weight, and the like of the two objects connected by the support.

Further, the above-mentioned support hook base tool according to the present invention can be manufactured by any method using any material or member, and one example thereof is a member forming a bottom, a hook portion and a connecting portion. A hook base tool for support is manufactured by connecting a member to be formed and a member forming a connection portion by welding or the like, and another example is to form a member forming a bottom portion and a hook portion. A hook base tool for support is manufactured by joining a member forming a connecting portion, a member forming a connecting portion, and a member forming a connecting portion by welding or the like, and still another example is a bottom portion and a hooking portion. The entire support hook base including the connecting portion and the connecting portion is manufactured by a forging method.

Of these, when the entire support hook base tool is manufactured by a forging method, the support hook base tool according to the present invention is formed of a forged product as a whole. According to this, it becomes possible to obtain a support hook base tool having sufficiently increased overall strength.

Even if the angle is set to 1, the load transmitted between the hook portion 30A of the support 11 and the hook base tool 10 anchored to the object is between the bottom portion 40 and the hook portion 41 of the hook base tool 10. , The connecting portion 42 connecting the bottom portion 40 and the hooking portion 41 and the wall portion 43 connecting the connecting portion 42 and the bottom portion 40 can effectively receive the wall. Unlike the case where the portion 43 does not exist, the connecting portion 42 is not deformed or the like by the load.

Therefore, according to the hook base tool 10 according to the present embodiment, when the load is transmitted between the support 11 and the object to which the hook base tool 10 is anchored, the support 11 supports the load. This makes it possible to effectively perform the support 11 between the object and the object, so that the support 11 can be used at various angles such as an acute angle, a 0 degree angle, and a 90 degree angle with respect to the two objects connected by the support 11. The support 11 can be used at an angle, and the usefulness of the support 11 can be improved.

Further, according to the hook base tool 10 according to the present embodiment, the connecting portion connecting the bottom portion 40 and the connecting portion 42 is a wall portion 43 having a width dimension in the length direction of the connecting portion 42. The width dimension of the connecting portion 42 in the length direction with respect to the wall portion 43 can increase the connecting strength between the bottom portion 40 and the connecting portion 42, and thus further support the load between the support 11 and the object. You will be able to do it effectively.

Further, since the width dimension of the wall portion 43 is the dimension over the entire length of the connecting portion 42, the connection strength between the bottom portion 40 and the connecting portion 42 by the wall portion 43 can be further increased accordingly. The load can be supported more effectively between the support 11 and the object.

Further, as described above, a part of the wall portion 43 on the hook portion 41 side is a support portion 43A extending from the hook portion 41 to the bottom portion 40, so that the hook portion 41 is connected to the connecting portion 42. The acting tensile force load is supported by the support portion 43A, and therefore a large tensile force load can be effectively supported.

Further, the support portion 43A extends from the hook portion 41 toward the bottom portion 40 at an acute angle β with respect to the bottom portion 40, and the acute angle β is the acute angle formed by the connecting portion 42 with respect to the bottom portion 40. Since it is larger than the angle α of, the support portion 43A is a position in the hook base tool 10 that can effectively support the load of a large tensile force, and the direction of the acute angle angle β is the direction of the acute angle angle α. Since they are the same, the area of the bottom portion 40 does not increase, so that the hook base tool 10 can be attached to an arbitrary position of the object to which the hook base tool 10 is fastened.

Further, in the hook base tool 10 according to the present embodiment, the wall portion 43 serving as the connecting portion connecting the bottom portion 40 and the connecting portion 42 has a reinforcing portion 44 bulging in the thickness direction of the wall portion 43.
