Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a protective fence for concrete structures such as concrete structures (frames) and concrete retaining walls and a mounting device therefor, and more particularly to balconies, balconies, corridors of concrete structures, etc. The present invention also relates to a mounting method and a mounting device for protective fences such as handrails and fences that are installed in places required for safety measures.

[0002]

2. Description of the Related Art Conventionally, various construction methods have been proposed for mounting this type of protective fence and are widely known. For example, as disclosed in Japanese Patent Application Laid-Open No. 7-331830, a fixing bolt is provided at the center of the lower end surface of the fence in a fixed state by screwing, while a fence is installed on a balcony of a concrete building. the section was drilled by the fixing hole drilling and the like for fixing the fixing bolt, after allowed injecting an adhesive such as Ebokishi resin to the fixing holes, contact with plugging the fixing bolt to the fixing hole
There is a mounting method in which the lower end of the fence pillar is fixed to the fence installation portion by flooding and filling the material between the upper surface of the fence installation portion and the lower surface of the fence pillar.

[0003]

By the way, FIG. 1 and FIG.
As illustrated in 2, fence installation to install and install a protective fence
Within the part B, there are structural muscles 13 that prevent the falling off . Therefore, in the conventionally known mounting methods including the above-mentioned Japanese Laid-Open Patent Application No. 7-331830, a core material such as a fixing bolt is fixed on the lower surface of the fence pillar and coaxially with the shaft axis of the pillar pillar. Since there is a construction method that adheres to the fixing hole of the fence installation part and is installed on the fence, for example, at the construction site where the protection fence is installed vertically and extends from several meters to several tens of meters, the fence installation to drill the fixing hole When structural muscles (lateral muscles for preventing falling) are present in the part, the structural muscles obstruct and the fixing holes cannot be formed. Therefore, it is necessary to cut and remove the structural muscles existing at the positions where the fixing holes are to be drilled and remove them, which requires additional work requiring labor and labor, which not only causes extension of the construction period. ,
In particular, the damage caused to the fence installation part (concrete structure) by cutting and removing the structural muscles was quite large.

In any of the conventional construction methods, the fixing of the core material such as the above-mentioned fixing bolt to the lower end of the fence post is performed by welding or screwing, and moreover, after fixing to the fixing hole by the adhesive material . Also, since a part of the core material and the welded part exist without being covered by the adhesive so as to be directly exposed to the inside and outside of the fence support, the exposed part of the core material and the welded part are long-term. There is a problem such as rusting during use, which causes looseness of the connection between the fence post and the core material and rattling, and the protective fence shakes, which causes psychological anxiety to people. I was holding a problem.

Further, as a core material such as a fixing bolt for fixing the fence post to a fixing hole of the fence installation portion through an adhesive , it is conceivable to use a stainless steel material excellent in corrosion resistance and corrosion resistance, but the stainless steel material is expensive. Because of the high cost and high cost, it is common to use a steel material that is cheaper than a stainless steel material as the main material of the core material. Therefore, there is a problem of service life due to rust due to infiltration of rainwater or the like. Further, in the conventional construction method, since the connection between the fence post and the fixing bolt is only by welding or screwing, sufficient strength cannot be obtained for connecting the fence post and the core material. That is, the horizontal strength required for the protective fence cannot be obtained sufficiently.

[0006] Further, in the conventional construction methods require feet cap to hide the base (foot) of including the extravasated Ebokishi resin fence posts corresponding to the lower surface of the fence post of the fence installation part an adhesive And That is, since many accessory parts are required, there is a problem in that the workability is poor, such as time-consuming attachment, and the cost is high.

[0007] In view of such conventional circumstances, the present invention has been accomplished by conducting research for many years, and an object of the present invention is to fix a fixing hole to a fence installation portion avoiding structural streaks. It is possible to pierce, and it is also possible to install and install fence posts that are integrated with the fence installation section. Also, the construction period can be greatly shortened and the cost can be reduced. An object of the present invention is to provide a mounting method and a mounting device for a protective fence for a concrete structure capable of adjusting the level of each fence pillar regardless of the finished state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific example of the embodiment of the present invention will be described with reference to the drawings. 1 to 6 show the mounting method and the mounting method of the present invention .
An example of a construction mode in which a protective fence A, a so-called handrail, is attached and installed on a fence installation portion B such as a veranda of a concrete building by a mounting device , and the installation interval of the fence posts 1 by the known installation method on the fence installation portion B is shown. bored by the dude and Sakuno part drilling such a fixing hole 2 in a straight line along the B, the fixing hole 2
The core material 3 is inserted into the housing in a loose fit and positioned in the fixing hole 2.
It intersects with the structural muscles 13 in the installation section B and projects from the fixing holes 2.
Put it out . Then, the protruding side of the core 3 protruding from the fixing hole 2 is freely inserted into the lower end of the fence column 1 to make the fence column 1 stand upright on the fence installation portion B, and in this state, the lower end opening of the fence column 1 is opened. Part and fence installation part B with draining slope
The form block 4 is set from the outer periphery of the lower end of the fence column 1 to the fence installation portion B so as to close the gap 14 formed between the fence block 4 and the fence block 4. Next, from the injection port 5 opened on the side surface of the fence post 1 to the fixing hole 2 at the filling level where the core material 3 is completely buried in the fence post 1 and the opening height L1 of the injection port 5 is reached. at least by an appropriate adhesive filler 6 having fluidity is injected filling, the lower end of the fence post 1 is fixed to the fence installation portion B, so as to place mounting the safety barrier a to該柵installation portion B over a I am doing it. After the adhesive filling material 6 is hardened, the mold block 4 is cut and removed.

In the figure, 7 is a head tree, 8 is a lower beam, and 9 is this head tree 7.
Is a grid between the lower crosspiece and the lower crosspiece, and 10 is an aluminum mold material or the like which is fixedly inserted in an appropriate range from the vicinity of the lower end opening to reinforce the fence post 1 itself. It is a square or round hollow reinforcing material.

The fence post 1 has a well-known structure which is made of aluminum and has a square shape and a hollow cylinder shape with an appropriate thickness. The post wall is located at the lower end side of the fence post, particularly above the upper end of the core 3 included therein. The injection port 5 is opened at the same time, and the adhesive filling material 6 is injected from the injection port 5 to the inside of the fence support 1 and the fixing hole 2 in a height range reaching the injection port 5.

The structure and material of the core material 3 are not particularly limited, and examples thereof include inexpensive steel pipe materials and bar materials, and other reinforcing bars. In the present embodiment, a reinforcing bar is used, and it is cut into a required length according to both the insertion range L2 to be incorporated in the fence support 1 and the insertion range into the fixing hole 2, that is, the depth range L3, and the epoxy resin is used. liquid as its entirety or illustrated by a suitable method such as dipping in the coating or the solution in its entirety, except for the inserted one end (lower end) to form a rust preventing film 11 in the fixing hole 2 ,
It is designed to prevent rust due to infiltration of rainwater and the like, and to prevent deterioration due to rust (see FIG. 3).

The rust preventive coating 11 may be applied by hot dip galvanizing or using any other material. in short,
Any material can be used as long as it can protect the core material 3 from invading rainwater and the like, and can form the rust preventive coating 11 on the surface of the core material 3 easily and at low cost.

Further, the longer the insertion range L2 of the core material 3 to be present inside the fence post 1 is, the more the adhesive filling material 6 is injected and filled to extend from the fixing hole 2 of the fence installation portion B to the inside of the fence post 1. It goes without saying that the joint strength between the fence installation portion B and the fence pillar 1 can be further strengthened by the joint pillar 12 formed and having the core 3 inside . In other words, by changing the insertion range L2 of the core 3 to be provided inside the fence post 1, it is possible to arbitrarily change the coupling strength of the fence post 1 with respect to the fence installation portion B and to realize high strength. High strength can be maintained for a long time.

Further, the thickness (outer diameter) of the core material 3 is not particularly limited, but as shown in FIG. When the fixing hole 2 is bored so as to cross over the structure, or when the fixing hole 2 is bored so as to pass the side of the structural muscle 13 while avoiding the structural muscle 13 as shown in FIG. , And the horizontal strength required for the installation location, for example, when the horizontal strength required for each floor is different, such as in an apartment house, the thickness corresponding to the horizontal strength required for those installation locations, for example, D10, D13, D16
Etc. are selected as appropriate. In other words, the strength of the joint pillar 12 formed by the adhesive filling material 5 injected and filled over the inside of the lower end side of the fence pillar 1 and the inside of the fixing hole 2 is set to D10 according to the horizontal strength required for each floor. , D13, D16 and the like, and the thickness is such that it can be reinforced by using one or several wires, and is not particularly limited.

The formwork block 4 closes a gap 14 formed between the lower end opening of the fence post 1 and the face B of the fence installation section,
It is intended to prevent the adhesive flowing out of the filling material 6 from 14. The mold block 4 is made of a material having a proper elasticity and a wettability to which the adhesive filler 6 is hard to adhere, for example, silicon, and has an inner surface shape substantially conforming to the outer peripheral shape of the fence post 1 and having an appropriate thickness. A formed inner frame 4-1 having a height, and this inner frame 4-1
To form a square ring (see FIG. 4) with an outer frame 4-2 that is also formed to have an appropriate thickness and height using urethane foam or the like having an appropriate elasticity (see FIG. 4). After the fence support 1 is inserted into the fixing hole 2 and the fence support 1 is made to stand upright on the fence installation part B, the gap 14 between the lower end opening of the fence support 1 and the fence installation part B is closed and a rough surface ( Uneven fence installation part B
The inner frame 4-1 made of silicon is set on the surface while being pressed against the fence installation section B (see the enlarged view of FIG. 3B).

In addition, one of the four sides of the frame material block 4 has a circular cut, and the form block 4 is opened from this cut. In this state, the lower end opening of the fence support 1 is opened. It is also possible to set so as to close the gap 14 generated between the fence installation section B and the fence installation section B. Then, it allowed injecting an adhesive filler material 6 from the inlet 5 of the fence post 1 filled with the same filler material 6 into the fixing hole 2 from the lower end side inside the fence post 1, after which the filling material 6 is allowed to cure It is removed by cutting (Fig. 3
(See (d)). As a result, the base of the fence post as in the past
There is no accessory such as a foot cap to hide the
What makes it possible to install and install a protective fence with a good finish
(See FIG. 6).

The form block 4 may be formed of silicon or urethane foam in the shape of a square ring, but it is of course free, but in order to increase the strength against horizontal load, adhesive filling of the fence support 1 is performed. When the filling level of the material 6 (the opening height L1 of the injection port 5) is increased, it is preferable that the material 6 is formed of silicon alone or a composite of silicon and urethane foam as described above. That is, by using silicon, the mold block 4 can be set so as to fit into the fence installation portion B having a rough surface (unevenness), and thereby the filling level of the adhesive filler 6 can be increased to increase the fence. Prop 1
Although the pressure of the adhesive filling material 6 inside becomes high,
Even if such a pressure change occurs, it is possible to reliably prevent the adhesive filler 6 from leaking.

The adhesive filling material 6 used in the present invention is not particularly limited, but it has excellent fluidity so that it can fill even a small gap, and the fixing hole 2 of the fence installation portion B can be filled with it. When filled, it fits into the fixing hole 2. That is, a milk cement that is partly infiltrating into the concrete on the inner peripheral surface of the fixing hole 2 and adapted to be integrated with the concrete is desirable, and non-shrink mortar is particularly desirable. Incidentally, the desirable consistency range of this non-shrink mortar is 7 to 13 (J ₁₄ funnels / second).

Next, claims 1 and 5 as described above
A method of attaching the protective fence A according to the present invention will be described.
First, the fixing holes 2 are bored at the installation intervals of the fence posts 1 of the fence installation section B of the stake out concrete building. At this time, when the structural muscles 13 become an obstacle and the fixing hole 2 of the depth range L3 corresponding to the strength requirement cannot be drilled at the marking position, the structural muscles 13 still erect the fence post 1. When it exists substantially directly below the axial center, as shown in FIG. 2 (a), a large hole is drilled to the depth reaching the structural muscle 13, and then the structural muscle 13 is crossed so as to cross it. By forming the Y-shaped fixing holes 2 in a substantially opposite direction by obliquely forming the holes, two core materials 3 having a required length and thickness are selected to form a substantially X-shaped shape.
Insert into the fixing hole 2 in a loose fitting manner so that the fixing hole 2
Crossing the structural muscles 13 in the fence installation section B located at
Both are made to project from the fixing hole 2 . Also, structural muscle 13
If there is a part outside the axis of the fence column 1, the crossing of the side of the structural muscle 13 is performed as shown in Fig. 5.
The fixing hole 2 is provided vertically so that the core member 3 having the required length and thickness is selected and inserted into the fixing hole 2 and fixed.
While crossing the structural muscles 13 located in the hole 2, the fixing hole 2
From the outside .

Then, the protruding side of the core material 3 protruding from the fixing hole 2 is freely inserted into the lower end of the fence post 1 to make the fence post 1 stand upright on the fence installation section B, and the lower end of the fence post 1 The formwork block 4 is set over the outer periphery of the lower end of the fence column 1 and the fence installation portion B so as to close the gap 14 formed between the opening and the surface of the fence installation portion B (state in FIG. 3B). At this time, by pressing the mold block 4 toward the fence installation section B side, as shown in the enlarged view, the inner frame made of silicon is set so that it fits into the rough surface (uneven) fence installation section B , and is bonded. The filler 6 is prevented from leaking surely.

After that, the adhesive filler 6 made of non-shrink mortar or the like is poured into the fence support 1 and the fixing hole 2 into which the core 3 is inserted by injecting it from the inlet 5 using the filling container C or the like. Filling is performed up to the filling level that reaches the opening height L1 of the inlet 5 (states of FIG. 2 (c) to (d)). At this time, the adhesive filling material 6 having excellent fluidity quickly flows into the gap between the core material 3 and the fixing hole 2 to fill the gap, and at the same time, the fixing hole 2
Part of the inner surface concrete is infiltrated so that it is integrated with the inner surface concrete.

After the injection work of the adhesive filling material 6 is completed, the filling operation is completed.
By cutting and removing the mold block 4 after the material 6 is completely hardened (the state of FIG. 2D), a series of installation and installation work of the protective fence A to the fence installation section B is completed.

Therefore, according to the mounting method and the mounting device configured as described above, the fixing hole 2 bored in the fence installation portion B and the core 3 to be inserted into the fence post 1 are free,
The structural muscle 13 becomes an obstacle and the fixing hole 2 is placed on the axis line of the fence post 1.
Structural muscles even when they cannot be drilled vertically along
By opening the fixing hole 2 avoiding the structural muscles 13 without cutting and removing the structure 13 and injecting and filling the adhesive filling material 6 made of non-shrinkable mortar or the like, the opening in the fence support 1 from the fixing hole 2 is formed. The fence pillar 1 is fixed to the fence installation portion B by the joint pillar 12 formed in the height L1 range. That is, since the fence support 1 rises up integrally from the fixing hole 2 of the fence installation part B and is integrally fixed to the fence installation part B by the joint support 12 having the core material 3 inside, the fence of the fence support 1 is fixed. The bond strength with respect to the installation portion B is effectively increased.

Further, since the core material 3 existing in the joint column 12 is protected by the anticorrosion coating 11, even if rainwater or the like enters the joint column 12 from the space between the fence installation section B, it does not rust. It does not cause. Therefore, there is no concern that the core material 3 will deteriorate due to rust or the like. In addition, a joint pillar formed in the fence pillar 1
When the top plate of 12 exists at the opening position of the inlet 5, rainwater or the like enters the fence post 1 through the upper end opening of the fence post 1 that is temporarily connected to the headstock 7. , Inlet 5
Functions as a drain. Therefore, it is possible to prevent rainwater or the like from accumulating in the fence support 1 and soaking into the connection support 12, thereby preventing the connection support 12 from deteriorating.
Therefore, the joint strength of the fence post 1 is maintained for a long period of time.

EFFECTS OF THE INVENTION Since the method of mounting the protective fence for a concrete structure and the mounting device thereof according to the present invention are constructed as described above, the following operational effects are achieved. In the present invention, it is inserted into a fixing hole formed in the fence installation portion in a loose fitting manner to cross the structural muscles.
By core material is inserted inherent in fence the strut protruding side which projects from the solid Teiana with is free, axial structural muscle the fixing holes becomes an obstacle, which is out ink at the installation interval of the fence posts Even when it is not possible to vertically pierce the structure, it is possible to pierce the structural hole without cutting and removing the structural muscle. In addition, by bonding and filling an adhesive filler made of, for example, non-shrinkable mortar, which has excellent fluidity, from the inside of the fence post to the fixing hole, the core material is built up inside the fence post from the fixing hole. Since the fence pillar can be integrally fixed to the fence installation portion by the pillar, the coupling strength of the fence pillar to the fence installation portion is effectively increased. Therefore, since it is possible to drill a fixing hole in the fence installation part avoiding the structural reinforcement, it is possible to solve the conventional big problem of damaging a concrete structure by cutting and removing the structural reinforcement. it is possible, proof
Several meters to several tens of meters along the fence installation section
It will be possible to install and install over. This allows the structure
By eliminating the need for additional work to remove the muscles, the contractor
The labor and effort to give can be reduced. In addition,
Since it is only necessary to inject the filling material once, the construction period can be shortened.
I can wait. Furthermore, the fence installation section should be integrated with the concrete.
From the fixing holes, rise up integrally inside the fence column and
Since it is possible to firmly fix the fence support to the fence installation part in the state where it is planned by the connecting support having the crossing core material ,
High horizontal strength against horizontal load can be expected.

Further, in the present invention, since the core material existing in the joint column is protected by the rust preventive film, even if rainwater or the like enters the joint column from the fence installation portion, it causes rust and the like. There is no. Therefore, there is no concern that the core material will deteriorate due to rust or the like.

In addition, in the present invention, the top plate of the connecting pillar formed in the supporting pillar is present at the opening position of the injection port, so that the upper end opening of the supporting pillar, which is temporarily connected to the umbrella, etc. When rainwater or the like infiltrates into the fence support from the above, the inlet functions as a drainage port. Therefore, rainwater etc. collects in the fence pillars,
Since it is possible to prevent the deterioration of the connecting columns caused by soaking into the connecting columns, it is possible to maintain the connection strength of the fence columns by the connecting columns for a long period of time.

In the present invention, a ring-shaped mold block made of silicon or urethane foam or both is used.
By setting over the outer periphery of the lower end of the fence post that stands upright with the fence installation part having a drainage slope, the gap generated between the lower end opening and the fence installation part is closed, and the fluidity is extended from the inside of the fence post to the fixing hole. It became possible to install a protective fence by injecting and filling the existing adhesive filler. That is, by developing a form block that can completely block the gap and completely prevent the flow of adhesive filler having fluidity to the outside, as described above, injection filling from the inside of the fence column to the fixing hole is performed. This enables the installation and installation of a protective fence that integrally fixes the fence support to the fence installation section.

Therefore, according to the present invention, it is possible to form the fixing holes while avoiding the structural streaks, while the fence installation part is integrated with the concrete by the connecting support pillar so that the fence support pillar is installed in a strong state. High strength can be expected because it can be fixed to. Moreover, since problems such as rust due to infiltration of rainwater and the like, loosening due to deterioration of concrete, and rattling are eliminated at all, it is possible to maintain the connection state of the fence columns with high strength for a long period of time. Therefore, the quality of the fence is stable for a long period of time without the swinging of the protective fence and causing psychological anxiety to the person, and there is no accessory part such as a foot cap for hiding the root of the fence post, unlike the conventional case. It is possible to provide an epoch-making method and device for mounting a protective fence for a concrete structure that enables installation of a protective fence with a good finish.
