Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure for burying a hanging metal fitting buried in a concrete wall, ceiling, etc., for hoisting a machine or the like using a pulley or the like.

[Problems to be solved by conventional techniques and ideas]

Buried metal fittings that are buried in the walls and ceilings of concrete buildings and are used as means for lifting machinery, etc. generally consist of a flat mounting plate and a stud dowel or anchor bolt fixed to one plane of this mounting plate. It is configured.

This buried metal fitting is attached to the formwork etc. via a mounting plate before pouring concrete, and then the concrete is poured, and after the formwork etc. are removed, the flat surface of the mounting plate is exposed on the concrete surface. ing.

In addition, when using a buried metal fitting buried in a wall, ceiling, etc. as a means for hoisting a machine, etc., weld the hook or other hanging metal fitting onto the flat surface of the mounting plate exposed on the surface of the wall, ceiling, etc. A pulley or the like is then hooked to this latch, and the machine or the like is lifted up via the pulley or the like.

However, when welding hooks and other latching fittings must be performed at high places,
Since it is dangerous, the work must be done carefully, which reduces work efficiency.

In addition, if the hook is welded onto the flat surface of the buried fitting before concrete pouring, holes must be made in the formwork, etc. used during concrete pouring to allow the hook to pass through. Efficiency decreases.

Furthermore, if buried metal fittings are buried in a part of reinforced concrete that is not reinforced,
There is a problem in that it is not possible to lift machines with large loads because they do not have enough strength to lift machines with large loads.

The present invention takes the above-mentioned facts into account, and aims to provide a structure for embedding lifting metal fittings that can improve work efficiency and ensure sufficient strength to lift heavy-loaded machines, etc.

[Summary and operation of the device]

The hanging metal embedding structure according to the present invention has a pipe-shaped hanging metal body bent so that both ends thereof face in the same direction, which straddles a reinforcing bar buried in solidified concrete, and the both ends are on the surface of the concrete. It is characterized in that it is buried in the concrete so as to be substantially flush with the concrete.

According to the above configuration, both ends of the hanging fitting main body are
It is buried so that it is almost flush with the surface of the solidified concrete, so when lifting a machine, etc., a wire is inserted from one end of the lifting fitting body to the other end, and a pulley etc. is attached to this wire. Machines, etc. can be lifted up via the pulley by hooking the pulley.

In addition, the lifting fitting itself is buried in the concrete so as to straddle the reinforcing bars buried in the solidified concrete, so even if the load of the above-mentioned machine, etc. is large, the strength required to lift the machine, etc. is Secured.

〔Example〕

1 to 3 show a hanging fitting according to this embodiment.

As shown in FIGS. 1 and 2, this embodiment includes a pipe 10 as a hanging fixture body and a mounting plate 12.

The pipe 10 has a hollow cylindrical shape. Also,
The pipe 10 has a semicircular axis with a middle portion bent such that both ends thereof face in the same direction. Both ends of the pipe 10 are opened to form openings 14.

Furthermore, mounting plates 12 are provided at four locations in each of the openings 14 of this pipe 10.

These mounting plates 12 are bent into an L-shape, and one plane is arranged on the same plane as the end face of the pipe 10 to form a flange, and the other plane is fixed to the outer peripheral surface of the pipe 10. ing.

Further, nail holes 16 for attaching the pipe 10 to a formwork or the like are bored in the one plane forming the flange.

As shown in FIG. 3, when the pipe 10 is buried in the concrete 18, the pipe 10 is located across two reinforcing bars 23. Further, both end surfaces of the pipe 10 and the surface of the solidified concrete 18 are flush with each other.

The operation of this embodiment will be explained below through the process of embedding the pipe 10 in concrete 18.

First, before pouring the concrete 18, the pipe 10 is positioned so as to straddle the reinforcing bars 23 buried near the inside of the formwork 20, as shown in FIG. Next, nails 22 are driven into the formwork 20 with both end surfaces of the pipe 10 in close contact with the flat surfaces of the formwork 20, and the pipe 10 is attached to the formwork 20 via the mounting plate 12. After that, concrete 18 is placed.

After the concrete 18 hardens, the formwork 20 is poured out. As a result, the mounting plate 1 forming the flange
2 and the opening 14 of the pipe 10 are flush with the surface of the concrete 18.

As described above, in this embodiment, even when the reinforcing bars 23 are buried near the inside of the formwork 20, the pipe 10 can straddle the reinforcing bars 23, so the work of attaching the pipe 10 to the formwork 20 requires It will not cause any trouble. Therefore, the work efficiency of the worker can be improved.

Further, when pouring the concrete 18, since the opening 14 of the pipe 10 is covered by the formwork 20, the concrete 18 does not block the opening 14. For this reason, the pipe 10 is connected to the concrete 1

can be inserted.

On the other hand, when using the hanging fitting according to this embodiment buried in the concrete 18 as a means for lifting a machine or the like (not shown), the wire 24 is connected from one opening 14 of the pipe 10 to the other opening 14.
By inserting the middle part of the wire 24 into the pipe 1 buried inside the concrete 18,
It can be supported within 0. Therefore, by hooking a pulley or the like (not shown) to both ends of the wire 24, it becomes possible to easily lift a machine or the like (not shown).

At this time, since the pipe 10 is buried so as to straddle the reinforcing bars 23, its support strength is high. For this reason,
Even if the load of the machine, etc. to be lifted is large, the machine, etc. can be surely lifted.

Furthermore, since the pipe 10 is supported by the concrete 18, if the pipe 10 has a large diameter, it is possible to lift a machine or the like (not shown) with a larger load.

In the above embodiment, the pipe 10 is formed into a hollow cylindrical shape, but it is not limited to this, and may have other shapes such as a rectangular tube shape, and a plurality of pipes 10 may be arranged in parallel. May be placed.

Furthermore, in the above embodiment, the mounting plates 12 forming flanges at both ends of the pipe 10 are fixed to the outer peripheral surface of the pipe 10, but the mounting plates 12 and the pipe 10 may be integrally molded. Alternatively, instead of the mounting plate 12, a pair of flat plates may be used, and both ends of the pipe 10 may be penetrated through these plates and then fixed to the pipe 10.
Other structures, such as forming flanges at both ends, may also be used.

Further, in the above embodiment, both end surfaces of the pipe 10 are arranged on the same plane as the mounting plate 12 forming the flange, but the present invention is not limited to this.
0 may be arranged inside the through hole of the flat plate, and the opening may be formed by the through hole of the flat plate. Alternatively, both end surfaces of the pipe 10 may be made to protrude from the flat plate and come into contact with the flat surface of the formwork 20, and the pipe 10 may be attached to the formwork 20 via the flat plate.
