Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a protective fence for concrete structures such as concrete buildings (frames) and concrete retaining walls, and an attachment device therefor, and more particularly to balconies, balconies, corridors of concrete structures, etc. The present invention also relates to a device for attaching a guard fence such as a handrail or a fence that is installed in a place necessary for safety measures.

[0002]

2. Description of the Related Art Conventionally, various construction examples have been proposed for mounting a protective fence of this type. For example, JP-A-3-
For the mounting disclosed in Japanese Patent No. 5534449, an anchor nut is inserted into a fixing hole drilled by a drilling process in a fence installation portion (parapet) such as a balcony,
While fixing by injecting an adhesive filler such as epoxy resin, a fence support member that is fastened to the anchor nut with bolts and nuts is attached inside the lower end of the fence post by screwing or fitting to fix the fence support. The lower end of the fence pillar is fixed to the fence installation portion by injecting the adhesive filler into the fence pillar through an injection hole provided on the lower end side of the fence pillar until the member is buried.

[0003]

However, in the above-mentioned mounting, the anchor nut is fixed to the fixing hole of the fence installation portion by the adhesive filler made of epoxy resin, and then the fence supporting member is anchored using the bolt and the nut. After tightening the nut, set the fence support member inside the lower end of the fence post, and attach the fence post to the fence support member by screwing, and finally bond it from the injection hole of the fence post into the post. A construction procedure for injecting the filler is required. That is, conventionally, unless the adhesive filler that fixes the anchor nut to the fixing hole of the fence installation portion is cured, the next work such as setting the fence support member to the anchor nut and erecting the fence support cannot be performed. . In addition, the troublesome work of setting the fence support member to the anchor nut using bolts and nuts is troublesome, which causes poor workability and delays the construction period.

Further, conventionally, an anchor nut placed in a fixing hole of a fence installation portion, a fence support member which is internally provided inside a lower end of the fence post and supports the fence post by screwing, and the fence support member is an anchor nut. Since it requires bolts and nuts to be built in and connected to, and a tube that prevents leakage of adhesive, and a foot cover that hides the base of the fence post, it is difficult to install as mentioned above, so workability is poor, Moreover, there is a problem that the cost becomes high as a whole.

The present invention has been made in view of such conventional circumstances, and an object of the present invention is to realize a simplified structure, a shortened construction period, and a low cost. An object of the present invention is to provide a device for mounting a protective fence for a concrete structure, which makes it possible to adjust the level of each fence pillar regardless of the finished state such as the levelness.

[0006]

Injecting and filling a flowable adhesive filler, By Hama material is removed the formwork block after curing, is that which is adapted to secure erected a fence post in the fence installation part. Here, there is no particular limitation on the method of fixedly inserting the coupling head portion of the support member into the fence post. For example, the width of the joint head is formed to be slightly larger than the inner dimension between the both side walls of the fence post, and is fixed by the press-fitting method. Or by forming the width of the coupling head that is the same as or slightly smaller than the inner dimension,
It is optional to insert the wire into the lower end of the fence post and fix it to the fence post by a screwing method using a fixing means such as a small screw.

The material of the supporting member is not particularly limited. For example, an aluminum drawing or extrusion molding material is used to form a substantially T-shape or a substantially T-shape in which the coupling head and the fixed leg are integrally connected. Form in a Y shape. Alternatively, a substantially T-shape or a substantially Y-shape in which the coupling head and the fixed leg are integrally connected by punching (pressing) using a metal plate material having a predetermined thickness that is cheaper than aluminum material It is optional to be formed into Further, it is preferable that a rust preventive coating is applied to the entire surface of the support member, or the surface of the joint head including at least the root portion of the fixed leg portion so as to prevent rust due to infiltration of rainwater or the like. The rust preventive coating is preferably applied using an epoxy resin, hot dip galvanizing, or a non-polluting inorganic heat-resistant, waterproof, touch-proof, anti-condensation paint (trade name: Upcon).

Further, the above mold block is made of silicon or urethane foam and has an inner surface shape substantially conforming to the transverse outer surface shape of the fence post, and has an appropriate height and thickness, or a silicon inner frame and urethane foam outer frame. From both of the above, it is preferable to form, for example, a rectangular ring shape having at least an appropriate height and thickness with an inner surface shape that substantially matches the outer shape of the cross section of the fence column. In addition, one of the four sides of this frame material block has a circular cut, open the frame material block from this cut, and in this state, set it over the outer circumference of the lower end of the fence post and the fence installation part, and adhesive filling material It is preferable to be able to remove it after it has hardened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific example of the embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an example of an embodiment in which a protective fence A, so-called handrail, is attached and installed to a fence installation portion B (parapet) of a veranda or the like of a concrete building by the installation device of the present invention. In the figure, 1 is a fence post, 2 is a support member, 3 is a form block, and 4 is a fixing hole (drill hole) drilled in the fence installation section B at a standing interval of the fence post 1 by a drilling process or the like. The support member 2 is shown inside the lower end of the fence post 1.
The fixed leg portion 2-2 of the support member 2 having the coupling head 2-1 fixedly inserted therein and protruding from the lower end opening of the fence post 1 on the substantially coaxial line is loosely fitted into the fixing hole 4. And install the fence support 1 upright on the fence installation section B. Then, the formwork block 3 is set from the outer periphery of the lower end of the fence column 1 to the fence installation section B so as to close the gap P formed between the lower end opening of the fence column 1 and the fence installation section B having a draining slope. Next, an adhesive filler 6 having at least appropriate fluidity from the inside of the fence column 1 to the fixing hole 4 from the filling port 5 opened on the side wall of the fence column 1 to a filling level reaching the opening height L1 of the filling port 5. By injecting and filling, the fence support 1 is fixed upright on the fence installation section B,
The protective fence A is attached to and installed on the fence installation section B. Then, the mold block 3 is removed after the adhesive filler 6 is cured. Also, in the figure, 7 is Kasaki, 8
Is a lower rail, and 9 is a grid between the headboard 7 and the lower rail 8.

The fence post 1 has a well-known structure which is made of aluminum drawn or extruded molding and has a square shape with an appropriate thickness and a hollow cylindrical shape, and a fixed leg portion of the supporting member 2 is provided from an opening at a lower end thereof.
The supporting member 2 can be attached and equipped in a state in which 2-2 is projected on a substantially coaxial line. In addition, the lower end side of the fence post 1, especially the middle portion in the height direction of the joint head 2-1 of the existing support member 2 or the joint head 2-1 as shown in the figure, is the adhesive filler 6.
The injection port 5 is opened at a predetermined height position such as a portion above the upper end of the coupling head 2-1 which is completely buried in the injection port 5.
The adhesive filler 6 can be injected and filled from the injection port 5 into the rail support 1 and the fixing hole 2 at a filling level reaching the opening height L1 of the above.

Although not shown in the drawings, in order to reinforce the fence pillar 1 itself over substantially the entire length of the inside of the fence pillar 1, an aluminum drawing or extrusion molding material, or a square or round shape made of other molding material. A hollow reinforcing material is fixedly inserted in the housing.

The supporting member 2 may be integrally formed by using an aluminum drawing or extrusion molding die material, but it is cheaper than the aluminum material and punched using a steel or other metal plate material having an appropriate thickness ( By press working), the coupling head 2-1 and the fixed leg portion 2-2 are integrally formed to have a substantially Y shape or a substantially T shape. Further, in this case, it is wasteful to perform punching by alternately changing the punching direction using a strip-shaped plate material having a width from the upper end of the coupling head 2-1 to the lower end of the fixed leg 2-2. It can be made cheaper and cheaper.

The joint head 2-1 serves to support the fence strut 1 by connecting with the fence strut 1, and the width thereof is fixed inside the lower end of the fence strut 1 by press fitting. In order to obtain it, it is punched and formed to have a size slightly larger than the inner size between both side walls 1-1 of the fence post 1.

The fixed leg 2-2 cooperates with the coupling head 2-1 to connect and support the fence post to the fixed hole 4 formed in the fence installation portion B at a predetermined opening and depth. The width is formed so that it can be loosely fitted into the fixing hole 4. The length of protrusion of the fixed leg portion 2-2 from the lower end of the coupling head 2-1 is set to an appropriate length in accordance with the insertion range into the fixing hole 2, that is, the depth range L2 of the fixing hole 4. It is formed by punching, and a retaining portion 2-20 is formed at the lower end thereof.

The supporting member 2 punched and formed in the above-described shape and size is coated with an epoxy resin solution or dipped in the solution, or the like, and the whole surface or the retaining portion is removed.
By forming a rust-proof coating 10 on the surface of the leg 2-2 and the coupling head 2-1 except the lower end side of the fixed leg 2-2 having 2-20, rust due to infiltration of rainwater etc. is prevented. , To prevent deterioration due to rust (see Fig. 2).

The anticorrosive coating 10 may be applied by hot dip galvanizing, or may be applied by using other materials such as non-polluting inorganic heat-resistant, waterproof, touch-proof, anti-condensation paint (trade name: Upcon). Be free. In short, it is only necessary that the support member 2 can be protected from invading rainwater and the like, and the rust preventive coating 10 can be formed on the surface of the support member 2 easily and at low cost.

The supporting member 2 is mounted on the fence support 1 by the above-described press-fitting method at the manufacturing factory and is carried to the construction site. Although not shown in the figure, the coupling head 2 of the supporting member 2 inserted and incorporated in the lower end of the fence 1 is shown.
The width of 2 is formed to be slightly smaller than the above-mentioned inner size, and after being inserted and incorporated inside the lower end of the fence post 1, a small screw or the like is screwed from the fastening holes provided on both side walls of the fence post 1 using a fixing means. It is optional, such as fixing to the fence post 1 by a method. Of course, this fixing means can be freely removed after the fence support 1 is vertically fixed to the fence installation portion B with the adhesive filling material 6.

Further, a connecting window 11 made of the adhesive filling material 6 is opened in the connecting head 2-1 of the supporting member 2, and the connecting window 11 is formed.
The supporting member 2 and the adhesive filling material 6, that is, the filling hardening material 12
Is integrated with. In other words, the coupling strength of the support member 2 to the fence support 1 is effectively increased (see FIG. 1 (b)).

The formwork block 3 closes the gap P formed between the lower end opening of the fence post 1 and the face of the fence installation portion B,
The flow of the adhesive filler 6 from P is prevented, and the level of each fence column 1 can be adjusted while the gap P is closed. That is, the level of each fence support 1 can be adjusted regardless of the finished state such as the levelness of the fence installation section B. The mold block 3 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 that is substantially conformed to the transverse outer peripheral shape of the fence post 1 and has an appropriate thickness. An inner frame 3-1 formed to have a height, and an outer frame 3-2 similarly formed to have an appropriate thickness and height by using urethane foam having appropriate elasticity so as to surround the inner frame 3-1. And to form a square ring shape (see FIG. 3), insert the fixed leg portion 2-2 of the support member 2 protruding from the lower end opening of the fence post 1 into the fixing hole 4, and install the fence post 1 into the fence installation section. In a state in which it is upright on B, the fence installation part B is still rough (uneven) so as to close the gap P between the bottom opening of the fence post 1 and the fence installation part B.
The inner frame 3-1 made of silicon is set on the surface while being pressed against the fence installation section B (see the enlarged view of FIG. 4B).

Incidentally, one of the four sides of the frame material block 3 is provided with a ring slit 13 and the frame material block 3 is opened from this ring slit 13, and in this state the lower end opening of the fence post 1 and the fence It is also possible to set so as to close the gap P generated between the installation portion B. Then, the adhesive filler 6 is added to the fence support 1
The filling material 6 is filled from the inside of the lower end side of the fence post 1 into the fixing hole 4 by injecting it from the filling port 5 of the above, and after the filling material 6 has hardened, the frame material block 3 is opened from the ring slit 13. To be removed (see FIG. 4 (d)).

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, filling and adhering to the fence column 1 is performed. When the filling level of the agent 6 (the opening height L1 of the injection port 5) is increased, it is preferable that the agent 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 3 can be set so that it fits into the fence installation portion B having a rough surface (unevenness), and thereby the filling level of the filling adhesive 6 is increased to increase the fence. Prop 1
Although the pressure of the filling adhesive 6 in the inside becomes high,
Even if such a pressure change occurs, the leakage of the filling adhesive 6 can be surely prevented.

As the adhesive filler 6 used in the present invention,
Is not particularly limited, but fills even small gaps
Has excellent fluidity that can be achieved, and is also a fixing hole for the fence installation part B
When it is filled in 4, it fits in the fixing hole 4. That is,
Part of the concrete on the inner surface of the fixed hole 2 is allowed to penetrate and
Familiar type to be integrated with the interior
Luk cement is preferred, especially non-shrink mortar.
Yes. By the way, the desirable system of this non-shrink mortar
Range of 7 to 13 (J ₁₄Funnel seconds).

Next, a method of mounting the protective fence A (construction example) by the mounting device having the above-described structure and detailed in this embodiment will be described. First of all, the fixed leg portion of the support member 2 protruding from the lower end of the fence post 1 into the fixing hole 4 formed at the installation interval of the fence post 1 at the fence installation portion B of the inscribed concrete building. Insert 2-2 (state of Figure 4 (a)). Next, the form block 3 is opened and set from the circular slit 13 so as to close the gap between the lower end opening of the fence column 1 and the plane B of the fence installation portion while the fence column 1 is upright (Fig. 4 ( State of b)). At this time, by pressing the mold block 3 to the side of the fence installation section B, the inner frame made of silicon is set so as to fit into the rough (uneven) fence installation section as shown in the enlarged view, and adhesive filling is performed. It ensures the prevention of leakage of the agent 6 (see the enlarged view).

After that, the height level of each of the fence supports 1 which are vertically erected in parallel along the fence installation portion B is adjusted within the height (thickness) range of the form block 3. Then, the adhesive filler 6 made of non-shrink mortar or the like is injected from the injection port 5 by using the injection container C or the like, and the fixing hole 4 into which the fixing leg portion 2-2 of the supporting member 2 is inserted in the fence support 1 is inserted. Fill into the interior to a filling level that reaches the opening height L1 of the injection port 5 (Fig. 4
(States from (c) to (d)). At this time, the adhesive filler 6 having excellent fluidity quickly flows into the small gap between the fixed leg portion 2-2 and the fixing hole 4 and is filled in the gap.
A part of the fixing hole 4 is made to penetrate into the inner concrete so that the fixing hole 4 can be integrated with the inner concrete.

After the injection work of the adhesive filler 6 is completed and the filler 6 is completely cured, the mold block 3 is cut into a circular cut 13
When the protective fence A is opened and removed (state of FIG. 4D), a series of installation work for the protective fence A on the fence installation section B is completed.

Therefore, according to the mounting device constructed as described above, the coupling head 2-1 is press-fitted and fixed to the fixing hole 4 formed in the fence installation portion B inside the lower end of the fence post 1 in a manufacturing factory or the like. The fixed leg portion 2-2 of the support member 2 protruding from the lower end opening is inserted into the fence support 1 which is upright on the fence installation portion B, leaving the upper end side of the coupling head 2-2. As shown in the figure, by filling and filling the fixing hole 4 with the adhesive filler 6 made of non-shrinkable mortar or the like until the filling level reaches the opening height L1 of the filling port 5 in which the joint head 2-1 is completely buried. , Installation of protective fence A to fence installation section B is completed.

Further, since the support member 2 is protected by the rust preventive film 10, even if rainwater or the like enters from between the fence installation portion B, it does not cause rust or the like. Therefore,
There is no concern that the strength of the support member 2 will deteriorate due to rust or the like.
In addition, since the top plate of the filling and hardening material 12 is made to exist at the opening position of the injection port 5, rainwater is introduced into the fence post 1 from the upper end opening of the fence post 1 that is temporarily connected to the headstock 7. The inlet 5 functions as a drainage port when infiltrating. Therefore, it is possible to prevent deterioration of the filling and hardening material 12 caused by rainwater or the like being accumulated in the fence and supporting pillar 1 and soaking into the filling and hardening material 12, so that the bonding strength of the filling and hardening material 12 with the filling and hardening material 12 is long-term. Will be maintained for the entire period.

[0029]

Since the mounting device for the protective fence for concrete structures of the present invention is constructed as described above, it has the following operational effects. At the manufacturing plant, the connecting head was fixedly inserted inside the lower end of the fence post, and the fixed leg part of the supporting member provided on each fence post of the protective fence was projected at the fence installation part at the construction site. Insert it loosely into the fixing holes to make it stand upright, and set the formwork block between the lower end periphery of each fence post and the fence installation part to close the gap, then extend from the injection hole of the fence post to the fixing hole. The installation work of installing the protective fence in the fence installation section is completed by injecting and filling the adhesive filler having excellent fluidity, such as non-shrink mortar, from the inside of the fence post to the fixing holes. Therefore, according to the present invention,
Insert the fixed legs of the support member into the fixing holes to erect each fence post of the protective fence, and then inject a bonding filler and attach the protective fence to the fence installation part to continue the series of operations. You can do it. That is, the mounting of the present invention as compared with the conventional apparatus in which the next work such as setting the fence support member by the bolt and the nut on the anchor nut cannot proceed until the adhesive filler for fixing the anchor nut in the fixing hole is cured. The device can perform a series of installation work of the guard fence continuously and rapidly without waiting time. In addition, by eliminating the need for installation work such as connecting the fence support member to the anchor nut with bolts and nuts, it is possible to reduce the labor and labor required for the contractor. Therefore, the construction can be simplified and the construction period can be shortened compared to the conventional equipment.

Further, the support member is stamped from a metal plate material such as steel, and is fixed to the inside of the lower end of the fence post, and the connecting head is made to project downward from the center of the lower end of the connecting head. Since it has a simple structure in which a fixed leg portion to be inserted into the fixing hole is integrally connected and formed in a substantially Y shape or a substantially T shape, it can be manufactured at low cost.
Also, because the support member is protected by the rust-proof coating,
Even if rainwater enters from between the fence installation parts, it will not cause rust. Therefore, there is no concern that the support member will deteriorate due to rust or the like.

According to the present invention, the filling level of the adhesive filling material into the fence column is set at the opening height L1 of the injection port provided in the fence column, so that it is temporarily connected to the headstock. When rainwater or the like enters the fence pillar from the upper end opening or the like, the inlet functions as a drainage port. Therefore, rainwater, etc. will not collect in the fence columns.

Further, according to the present invention, a ring-shaped form block made of silicon or urethane foam or both is set over the outer circumference of the lower end of the fence column which stands upright with the fence installation section having a drainage gradient. The gap P created between the opening and the fence installation part was closed, and it was possible to install and install a protective fence by injecting and filling a fluid adhesive filler from inside the fence post to the fixing hole. That is, by developing a form block capable of completely closing the gap P and completely preventing the flow of the adhesive filler having fluidity to the outside, as described above, injection is performed from the inside of the fence support to the fixing hole. It is possible to install and install a protective fence that fills and fixes the fence support to the fence installation unit.

Further, with the development of the form block, the height level of each of the fence pillars that are made to stand upright in parallel along the fence installation part can be adjusted regardless of the finished state such as the levelness of the fence installation part. It became possible to install and install a protective fence that can be adjusted within the thickness (height) range.
