メージがかなり大きいものとなっていた。By the way, as shown in the figure, there is a structural line for preventing falling off in a fence installation portion for installing and installing a protective measure. Therefore, the above-mentioned Japanese Patent Application Laid-Open
In the conventionally known mounting method including the construction method of No. 331830, a core material such as a fixing bolt is fixedly provided on the lower surface of the fence post on the same axis as the axis of the post, and the fence installation portion is provided. Since there is a construction method of bonding and fixing to fixing holes, for example, at a construction site where a protective fence is installed vertically and extends from several meters to several tens of meters, structural bars (for fall prevention) are installed in the fence installation part where the fixing holes are drilled. When the transverse line exists, the structural line becomes an obstacle, and the fixing hole cannot be formed. For this reason, it is necessary to perform additional work that requires labor and labor, such as the fact that it is necessary to cut and remove structural bars that exist at the position where the fixing hole is drilled, which not only causes an increase in the construction period In particular, the damage to the fence installation part (concrete building) due to the cutting and removal of structural bars was considerably large.

えていた。[0004] In any of the conventional construction methods, the fixing of the core material such as the fixing bolt to the lower end of the fence post is performed by welding or screwing, and after the fixing to the fixing hole by the adhesive. Since the core and part of the core are directly exposed to the inside and outside of the fence post without being covered by the adhesive, the exposed part of the core and the weld are prolonged. There is a problem such as rusting during use, which may cause looseness of the connection between the fence post and the core material and rattling, etc., and the protective fence shakes and gives psychological uneasiness to people. I had a problem.

In general, a steel material that is cheaper than a stainless steel material is used as a main material of the core material because of its high cost and high cost. For this reason, there is a problem of a service life due to rust due to intrusion of rainwater or the like. In addition, in the conventional construction method, since the connection between the fence post and the fixing bolt is performed only by welding or screwing, sufficient strength for connecting the fence post and the core material cannot be obtained. That is, the horizontal strength required for the protective fence cannot be sufficiently obtained.

And That is, since many accessory parts are required, there is a problem that the workability is poor, such as a time-consuming installation, and the cost is high.

In the present embodiment, a reinforcing bar is used, and cut into a required length according to both the insertion range L2 to be internally provided in the fence support 1 and the insertion range into the fixing hole 2, that is, the depth range L3. As shown in the figure, a rust-preventive coating 11 is formed on the entire surface or on the entire surface except for one end side (lower end side) inserted into the fixing hole by an appropriate method such as applying a liquid or dipping in the liquid. And
It prevents rust caused by rainwater and other intrusions, and prevents deterioration due to rust (see Fig. 3).

It goes without saying that the connection strength between the fence installation portion B and the fence support 1 by the connection support 12 having the core material 3 formed can be further enhanced. That is, by changing the insertion range L2 of the core material 3 which is provided inside the fence support 1, the coupling strength of the fence support 1 to the fence installation portion B can be arbitrarily changed, and high strength can be realized. High strength can be maintained for a long time.

強度が期待できる。The method and apparatus for mounting the protective fence for concrete buildings according to the present invention have the following functions and effects because they are configured as described above. In the present invention, since the core material inserted into the fixing hole formed in the fence installation portion and inserted inside the fence post is free, the structural hole becomes an obstacle and the fixing hole is placed at intervals of the fence post installation. Even in the case where it is impossible to pierce perpendicularly to the blackened axis, it is possible to pierce the fixing hole avoiding the structural muscle without cutting and removing the structural muscle. In addition, by injecting and filling an adhesive filler made of, for example, non-shrink mortar having excellent fluidity from the inside of the fence post to the fixing hole, a connection having a core material rising inside the fence post integrally from the fixing hole. Since the fence post can be integrally fixed to the fence installation part by the support, the connection strength of the fence post to the fence installation part is effectively increased. Therefore, according to the present invention, since it is possible to drill a fixing hole in the fence installation portion avoiding the structural bar, it is possible to damage the concrete building by cutting and removing the structural bar as in the related art. The problem can be solved.
In addition, since the additional work for removing the structural bar becomes unnecessary, the labor and labor given to the contractor can be reduced. In addition, since the work of injecting the adhesive filler only needs to be performed once, the construction period can be shortened. Furthermore, since the fence post can be firmly fixed to the fence installation part in a state where the fence installation part is integrated with concrete, high strength of horizontal strength against a horizontal load can be expected.

る。In the present invention, a mold block formed in a ring shape by using silicon or urethane foam or both is used.
The gap between the lower end opening and the fence installation part is closed by setting the fence installation part having the drainage gradient and the fence support that stands upright on the outer periphery of the fence support, and the flowability from inside the fence support to the fixing hole is reduced. It is possible to install a protective fence by injecting and filling the adhesive filler. That is, by the development of a mold block capable of completely closing the gap and completely preventing the flow of the adhesive filler having fluidity to the outside, as described above, the filling from the inside of the fence post to the fixing hole is performed. In this way, it is possible to attach and install a protective fence that integrally fixes the fence post to the fence installation part.
