Description

[Detailed explanation of the idea] The present invention relates to a reinforcing bar support with a synthetic resin cap.

The lower ends of the leg rods of steel wire rebar supports are exposed to the outside from the concrete wall surface after concrete is poured, and rust occurs. This problem of rusting can be solved, for example, by applying a synthetic resin cap to the lower end of the leg rod of the reinforcing bar support. Conventionally, various structures have been proposed as such reinforcing bar supports with synthetic resin caps, but
Conventional models generally have three or more leg rods, which is a large number, and it is necessary to apply a synthetic resin cap to each of the many leg rods, which inevitably results in a complicated structure. A type that can be used for both upper and lower muscles has a more complicated structure and is inevitably expensive.

The purpose of this invention is to provide a reinforcing bar support with a synthetic resin cap that can be used for both upper and lower reinforcement, has an extremely simple structure, and can be provided at low cost. A reinforcing bar receiving main body 1 made of iron wire having an upper reinforcing bar receiving part 2 in the center of the connecting rod 1a at the upper end, both leg levers 1b of the main body 1,
1b', a vertical hole 3a in the center of the upper surface,
Synthetic resin caps 3, 3' inserted at 3a'
The synthetic resin caps 3, 3' have projecting portions 3b on both sides extending in a direction perpendicular to the axis of the connecting rod 1a to provide the main body 1 with erectability.
3b, 3b', 3b', directly facing overhanging parts 3b,
This invention relates to a reinforcing bar support with a synthetic resin cap, characterized in that lower reinforcement receiving portions 4, 4' are formed at the upper end of at least one of the two sets 3b'.

The present invention has the structure as described above, and has a gate-shaped main body 1.
The synthetic resin caps 3, 3' inserted into the lower ends of the leg rods 1b, 1b' have overhanging portions 3b, 3' extending from both ends in a direction perpendicular to the axis of the connecting rod 1a.
In b, 3b', and 3b', since the main body 1 is given standing ability, the main body 1 is gate-shaped and simply has two leg rods 1.
b, 1b', it is possible to obtain the same stable and reliable erectability as the conventional one having three or more leg rods.

According to the present invention, the reinforcing bar receiving body 1 may have an extremely simple structure such as a gate type,
Therefore, it is possible to reduce the amount of iron wire used and facilitate wire processing, and the main body 1 has two leg rods 1b,
1b', the number of synthetic resin caps 3, 3' required is only two, and the overall manufacturing cost can be significantly reduced.

Furthermore, an upper reinforcement is attached to the receiving part 2 of the connecting rod 1a of the reinforcing bar receiving body 1, and an overhanging part 3 of the synthetic resin cap 3, 3' is attached.
The lower reinforcement can be supported on the receiving parts 4 and 4' at the upper ends of b and 3b',
It also has the feature of being able to be used as both an upper and lower reinforcement holder.

In the present invention, the leg rods 1b, 1 of the reinforcing bar receiving body 1
To insert the synthetic resin caps 3, 3' into b',
It is advantageous to do this with the rotation stopped, for example, when the leg rod 1
The lower ends of b, 1b' are made into a square cross section, and this is inserted into the square vertical hole 3 on the top surface of the synthetic resin caps 3, 3'.
A, 3a' may be inserted. In this case, the entire reinforcing bar receiving body 1 may have a square cross section, or the vertical hole 3 may have a rectangular cross section.
Only the portions inserted into a and 3a' may have a rectangular cross section.

Further, the lower reinforcement receiving portions 4, 4' may be formed on any of the two sets of overhanging portions 3b, 3b' as shown in the figure.
In this case, it is advantageous if the heights of the receiving parts 4, 4' of each set are set to be different, so that they can be used depending on the concrete cover thickness.

In addition, when the reinforcing bar support is placed on a base surface lacking in hardness such as styrofoam, in order to prevent it from sinking into the base surface, the lower ends of the synthetic resin caps 3, 3' are attached as shown in Figure 2. Warp portions 5, 5' can be formed in the portions.
