2. Description of the Related Art The applicant of the present invention has already filed Japanese Utility Model Publication Sho 63-2536.
A concrete anchor for mounting a ramp described in Japanese Patent No. 6 is proposed. In this anchor, the anchors are arranged on the axes of both legs of the gate main body that is bent in a gate shape, and the anchor portions are engaged with the concrete drilling holes.
The trumpet having such a structure is excellent in supporting a moment load applied to the root portion of the trump body by a vertical load applied thereto in an ideal state. However, it is desired that the structure is simpler and the cost can be reduced. For example, in various construction works, a temporary trap provided on a wall surface used only during the construction may be a trap having an extremely simple structure.

The simple trap having the plate 12 as shown in FIG. 6 has the following drawbacks. First, if there are irregularities on the concrete wall surface, there is a partial gap between the plate 12 and the wall surface, which is bad for the appearance. In particular, there is a drawback in that a gap is apt to be formed between the plate 12 and the wall surface at the anchor attachment portion, which reduces the supporting force of the anchor. That is, when a load in the direction of gravity is applied to the trap body 2, the moment generated at the root portions of both legs of the trap body 2 cannot be effectively supported.
Also, the anchor bolt hole 4 for mounting the anchor is a plate.
Since it exists on the center line parallel to the longitudinal direction of 12, when the excessive gravity is applied to the trap body 2, the root portion thereof is easily twisted, and the tip portion of the trap body 2 tends to drop downward. Furthermore, the trap body 2 and the plate 12
It is a separate member, and there is a drawback that it is relatively troublesome to firmly connect the root portion. At the same time, there has been a drawback that the root portion is corroded during many years of use, and the plate and the trap body are easily separated from each other.

The operation and effect of the present invention is such that the side surface of the wall surface abutting portion 3 which is orthogonal to the plane formed in the gate shape of the main body 2 of the tapping is brought into contact with the concrete wall surface so as to project from the wall surface. The anchor bolt is inserted into the anchor bolt hole 4 and the main trap is fixed to the wall surface. By mounting one or more such traps in the vertical direction, they can be used as footrests when moving up and down the wall surface. As described above, the trumpet of the present invention has wall contact portions 3 and 3 integrally bent at both ends of the trump body 2, and the anchor bolt holes 4 are formed therein in the gate-shaped plane of the leg portion 1. Since it is provided so as to be separated from each other in the direction orthogonal to, the main trap can be easily fixed by the anchor. At the same time, when used, the anchor supports the trump at a position distant upward from the root portion, so that the moment load applied to the root portion of the leg portion 1 and the wall surface abutting portion 3 is relatively small. Even a small anchor can be sufficiently supported.

That is, the load in the direction of gravity applied to the trap body 2 is applied as a moment load to the root portion thereof and acts in the direction of pulling out the anchor, but between the anchor and the root portion of the trap body 2, the trap body is provided. Since they are arranged in a direction orthogonal to the gate-shaped plane of 2,
The separation distance becomes a part of the arm length of the opposite moment against the moment. Therefore, in comparison with the conventional simple trap (having a connecting plate) shown in FIG. 6, the trap of the present invention can sufficiently support with a relatively small anchoring force due to its structure. Further, as another drawback of the conventional type, it is not affected by the above-mentioned unevenness between the two leg portions.
That is, even if there are irregularities between the two leg portions of the trap body 2, the wall abutting portions 3 projecting from both leg portions of the trap body 2 make the main trap adhere to the wall surface regardless of the irregular portions. And can be easily fixed. Moreover, since the turret body 2 and the wall surface abutting portion 3 are made of an integrally formed body in which the long material is bent and deformed, the number of parts is extremely small and mass production is excellent and can be provided at low cost. Further, since the trap body 2 and the wall surface abutting portion 3 are made of the same material, there is no joint portion between them, and a high strength trap can be configured.

Next, the round bar material is bent to form the trap body 2 and the wall surface abutting portion 3, and the flat wall enlarged portion 7 is provided with a flat enlarged portion 7, and the flat enlarged portion 7 is anchored. In the case where the bolt hole 4 is formed, bending deformation at each part is easy at the time of manufacturing the trap, and since the anchor bolt hole 4 is provided in the flat enlarged portion 7, the strength of the anchor bolt hole 4 peripheral part is increased. Can be maintained. Further, in the structure in which the thickness direction of the flattened expanded portion 7 is substantially aligned with the axis of the wall surface abutting portion 3, there is an effect that the flattened expanded portion 7 can be easily deformed and its strength can be maintained high. Furthermore, in the case where the end surface on the wall surface side of the flattened enlarged portion 7 and the outer peripheral surface on the wall surface side of the other wall surface abutting portion 3 are formed so as to substantially coincide with each other, a wall washer is not required on the wall surface side. The contact length between the contact portion 3 and the wall surface can be increased to provide a trap with a small number of components and easy mounting.
