Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting components on a ceramic wall, and more particularly to a method for mounting a component such as a gutter fitting on a ceramic wall finished by laying a large-sized ceramic plate on an outer wall of a building. The method is intended for mounting.

[0002]

2. Description of the Related Art There is known a technique of finishing an outer wall of a building such as a general house with a ceramic cladding plate having a relatively large tile shape. The wall surface finishing structure using the ceramic armor plate has advantages such as excellent weather resistance, less susceptibility to scratches and dirt, and easy cleaning of dirt.

[0003] To finish the wall with a ceramic exterior plate,
A method has been adopted in which a base panel made of plywood or gypsum board is laid and attached to the surface of a wall drive made of concrete, steel frame or wood, and a ceramic exterior plate is joined using an adhesive. The ceramic armor plate has a rectangular shape having a certain dimension of about several tens of cm, and the rectangular ceramic armor plates are arranged vertically and horizontally in a grid or in a staggered manner.

[0004]

In order to attach, for example, a downspout to a wall surface on which a ceramic armor plate has been installed, it is necessary to fix a downspout mounting bracket to the wall surface using mounting screws. However, since the ceramic exterior plate has the property of being hard and brittle, and has a small thickness, if the mounting screws such as wood screws are directly screwed into the ceramic exterior plate to fix the metal fittings, the work of screwing in the mounting screws is difficult. In this case, the ceramic exterior plate may be cracked or broken by the impact or vibration of an external force applied from a tool or the like. In a typical construction site, the mounting screws are often mounted with a machine tool, and it is difficult to adjust the screwing force, so that the ceramic exterior plate is frequently damaged.

[0005] For this reason, it has been difficult to attach parts such as metal fittings to the wall surface on which the ceramic armor plate has been installed. An object of the present invention is to make it possible to easily and surely attach components such as the metal fittings to a ceramic wall using the above-mentioned ceramic armor plate.

[0006]

A method of mounting a component on a ceramic wall according to the present invention is a method of mounting a component on a finished ceramic wall by attaching a ceramic plate to a wall via a base plate. Forming a mounting hole penetrating the plate and the base plate, and inserting an expanding plug having a substantially cylindrical screw hole at the center and having an expandable tip into the mounting hole, Step (b) in which the front end of the expansion plug protrudes from the back side of the base plate, and the rear end of the expansion plug protrudes from the surface of the ceramic plate. The process of fixing the parts to the base plate via the expansion plug by expanding the tip
(c).

[Wall surface] The present invention is applied to a wall surface similar to a building such as an ordinary general house or an apartment house. Any of a concrete structure, a steel frame structure, a wooden structure, and a combination thereof may be used. The wall surface may be an outer wall surface or an inner wall surface on the indoor side. For the wall surface, a base plate is attached to a wall drive such as a concrete structure.

As the base plate, the same base plate as used for ordinary wall construction is used, and examples thereof include plywood, gypsum board, and fiber board. On the back side of the base plate, there is provided a gap in which the tip of the expanding plug can be arranged. By attaching the base plate to the surface of the wall driving body via a bar, a gap can be provided on the back side of the base plate. A space serving as a gap may be provided in the wall drive.

[Ceramic plate] The same ceramic plate as that used for ordinary wall surface finishing is used. The ceramic plate is manufactured by forming a ceramic material such as glass into powder, granulated powder, or slurry, forming the plate into a plate shape, and then firing. If a foamable material is used as the ceramic material, a ceramic plate made of foamed ceramic can be obtained.

[0010] As the ceramic plate, a laminate of layers of different materials can be used. For example, a ceramic plate in which a main body layer exhibiting basic characteristics such as strength and a decorative layer exhibiting surface texture and characteristics are laminated can be used. There is also a ceramic plate in which another material is embedded in a pattern on the surface. The ceramic plate usually has a rectangular plate shape having a certain standard dimension. Those manufactured in an L-shape or a U-shape according to the structure of the building in advance, or those having an arc-shaped outer shape can be used. In the corners of buildings and the like, a three-dimensional ceramic plate having an L-shaped or arc-shaped cross section may be used.

The dimensions of the ceramic plate are set appropriately.
For example, a ceramic plate having an outer diameter in the largest direction among the passing diameters of the ceramic plates, that is, a maximum outer diameter of 300 mm or more is used. In the case of a rectangular plate-shaped ceramic plate, one having a length of 300 mm or more in both the vertical and horizontal directions can be used. The thickness of the ceramic plate varies depending on the material used, the required strength characteristics, and the like, but is usually set in the range of 5 to 30 mm, and preferably about 7 to 18 mm.

The ceramic plate is bonded and fixed to the base plate via an adhesive. By scattering the adhesive in spots, it is possible to allow a certain deformation between the ceramic plate and the base plate, thereby preventing the ceramic plate from being damaged due to thermal deformation or displacement with time. it can. If an elastic adhesive is used as the adhesive, the above function is further improved. The arrangement pattern of the ceramic plates can be freely set, and they can be arranged vertically and horizontally in a lattice pattern or in a staggered pattern.

A joint finish can be performed by providing a joint gap between adjacently arranged ceramic plates and filling a joint agent or inserting a joint material made of synthetic resin, rubber, or the like. [Parts and Mounting Screws] As the parts, any exterior and interior housing parts that need to be attached to the wall of the building are used. The parts are made of materials such as synthetic resin, metal, ceramic, and wood. Specific examples include mounting fittings such as downspouts, cables, pipes, and wires, illuminating lights and security devices or their mounting fittings, mounting fittings for shelves and shelves, and hanging fittings.

[0014] In addition to ordinary screws or bolts, wood screws, screw screws, tap screws,
A device equipped with a mechanism that is screwed while cutting a screw by itself is also used. The mounting screw may be provided separately from the component, or may be a component in which the mounting screw is integrally formed.

A sealing ring made of a sealing material such as rubber can be attached to the lower surface of the head of the mounting screw. The sealing ring closes a gap formed between the lower surface of the head portion of the mounting screw and the component or the expansion plug, and can improve the sealing performance. [Expanding plug] Conventionally, a plug which is known as a component used for attaching a screw component to a gypsum board or a plywood is used.

Usually, it is made of a flexible synthetic resin, a relatively soft metal or the like, and has a substantially cylindrical shape. The center is provided with a screw hole into which a mounting screw for mounting the component can be screwed. A screw hole is a hole in which a screw groove is not completely formed in addition to a screw hole that is completely formed in advance, and has a structure in which a screw groove is formed by screwing in a mounting screw such as a tap screw. May be.

The distal end of the expansion plug can be expanded toward the outer periphery by screwing a mounting screw into a screw hole. As the expanding mechanism, a mechanism similar to a normal expanding plug can be employed. For example, a notch is made at the tip of the flexible expanding plug, and the mounting screw is screwed into a screw hole having a smaller diameter than the mounting screw, so that the distal end of the expanding plug is expanded as the mounting screw advances. Can be opened.

The length of the expansion plug is set to be at least larger than the total thickness of the ceramic plate and the base plate. [Working process] Formation of mounting holes: Mounting holes formed in the ceramic plate and the base plate are set in accordance with the outer diameter of the expanding plug. A diameter that is equal to or slightly smaller than the outer diameter of the expanding plug is preferable.

The mounting holes can be formed using a normal drill or the like. It is possible to use a ceramic drill that can efficiently perform drilling without damaging the ceramic plate. By injecting a caulking agent into the processed mounting hole, the hermeticity of the mounting hole can be improved. A caulking agent for ordinary construction can be used. Arrangement of the expansion plug: Push the expansion plug into the mounting hole.

The front end of the expansion plug projects from the back side of the base plate by a predetermined length. By appropriately setting the amount of protrusion of the base plate to the back side, it is possible to reliably exert the function of expanding the tip of the expansion plug or the function of fixing the expansion plug. The rear end of the expansion plug is made to protrude from the surface of the ceramic plate. By appropriately setting the protrusion amount of the ceramic surface, the load applied to the ceramic plate can be reduced. Specifically, the protrusion amount is set to 0 to 3
Set to a value in the range of mm.

Screw-in mounting screw: The mounting screw provided integrally with the component may be directly screwed into the expansion plug, or a mounting screw prepared separately from the component may be inserted into the mounting screw insertion hole or mounting screw of the component. The expansion plug may be screwed through the insertion groove. As the mounting screw is screwed in, the tip of the expanding plug expands. The expanding tip presses the through-hole of the base plate outward, thereby producing an action of fixing the expansion plug to the base plate. In addition, on the back side of the base plate, the tip of the expansion plug greatly expands outside the through hole of the base plate.

As a result, the base plate, the ceramic plate, and the components are sandwiched and tightened between the head of the mounting screw and the expanded portion at the tip of the expanded plug. In other words, the expansion plug, the mounting screw and the component are firmly fixed to the base plate fixed to the wall drive.
At this time, since the rear end of the expansion plug protrudes from the surface of the ceramic plate, the head and parts of the mounting screw do not come into contact with the surface of the ceramic plate. Does not act directly,
Damage to the ceramic plate can be prevented.

When the mounting screw is sufficiently tightened, the expanding plug is compressed and deformed in the axial direction, and the head of the mounting screw and the back surface of the component may come into contact with the surface of the ceramic plate. Even in such a case, the load applied to the ceramic plate is smaller than the load such as the tightening force generated on the mounting screw and the expansion plug, and even if the mounting screw is strongly tightened, the selenium plate is not damaged.

In this way, after the component mounting with the mounting screw is completed, another component is supported by the component,
Even when a load of an external force is applied when the component is used, the component and the mounting screw are fixed to the base plate via the expansion plug, so that no excessive external force acts on the ceramic plate. Therefore, it is possible to prevent the ceramic plate from being damaged during use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIGS. 1 to 4 shows a case in which a support fitting of a downspout is attached to a ceramic wall surface with an attachment screw. First, FIG. 4 shows a basic structure of a ceramic wall surface. A ground plate 20 made of a plywood, a gypsum board, or the like is adhered to a surface of the wall driving body 10 made of concrete or a steel frame via a bar member 22 made of wood or the like. A ceramic plate 30 made of a foamed glass ceramic plate is adhered to the surface of the base plate 20 with an adhesive 32 arranged in a spot shape.

Parts are mounted on the ceramic wall having the above structure. As shown in FIG.
Then, the mounting holes 34 and 24 penetrating the base plate 20 are processed. Processing of the mounting holes 34 and 24 is performed using a normal drill tool. The inner diameters of the mounting holes 34 and 24 are designed according to the outer diameter of the expanding plug. For example, a mounting hole 3 with an inner diameter of 8 mm
4, 24 are perforated.

After drilling, the mounting holes 34 and 24 are cleaned with a brush or the like to remove fine processing debris. Next, a caulking agent is injected into the mounting holes 34 and 24. As shown in FIG. 3, the expansion plug 40 is attached to the attachment holes 34 and 24. If the caulking agent has been injected, the expanding plug 40, the base plate 20, and the ceramic plate 3
The gap between them is closed, and the sealing performance is improved.

The expansion plug 40 is formed of a molded article of a flexible synthetic resin, and has a cylindrical shape as a whole. The outer diameter of the expanding plug 40 is set slightly larger than the inner diameter of the mounting holes 24 and 34. A screw hole 42 is formed in the center of the expansion plug 40. One end of the screw hole 42 has a relatively large inner diameter, but the inner diameter gradually decreases from the middle to the other end. Further, the expanding plug 40 is provided with a cutout 44 from the end face of the small diameter screw hole 42 toward the middle.

The tip of the expanding plug 40 on the side where the cut 44 is formed is pushed into the mounting holes 34 and 24 from the front side of the ceramic plate 30. The expansion plug 40 is elastically deformed and fitted into the mounting holes 34 and 24. Expanding plug 40
Of the base plate protrudes to the back side of the base plate 20. Expansion plug 4
The rear end of 0 is slightly projected from the surface of the ceramic plate 30. The protrusion amount G is set to 0.5 mm.

In this state, of the expanding plug 40, the position where the diameter of the screw hole 42 starts to narrow and the deep end of the cutout 44 are arranged within the range of the base plate 20. As shown in FIG.
2 is used to attach the component 50. The component 50 is formed by press-forming a metal plate, and is a support fitting for supporting the downspout. The component 50 has a mounting hole 56 through which the mounting screw 52 is inserted. The mounting screw 52 is a tap screw having a conical tip. On the lower surface of the head of the mounting screw 52,
A sealing ring 54 made of a ring-shaped rubber is fitted.

The component 50 is arranged on the end face of the expanding plug 40, and the mounting screw 52 is screwed from the mounting hole 56 of the component 50 into the screw hole 42 of the expanding plug 40. In the state where the component 50 is arranged on the end face of the expansion plug 40, the rear surface of the component 50 is only in contact with the expansion plug 40, but does not contact the surface of the ceramic plate 30, and there is a slight gap G. It has become.

When the mounting screw 52 is screwed in, the screw advances smoothly through the portion of the expansion plug 40 where the diameter of the screw hole 42 is large at first. In FIG. 1, for the sake of simplicity of the drawing, the unevenness of the screw groove is not shown on the outer periphery of the mounting screw 52, but there is a screw groove on the outer circumference of the mounting screw 52, and the shape corresponding to the screw groove is provided. Are cut into the inner surface of the screw hole 42 of the expanding plug 40.

When the mounting screw 52 advances to a place where the inner diameter of the screw hole 42 is narrow, the screw hole 42 is expanded outward in accordance with the outer diameter of the mounting screw 52 as the mounting screw 52 is screwed. The expansion plug 40 is deformed so as to expand outward at the cut 44. When the expansion plug 40 expands outward, the expansion plug 40 is strongly pressed against the mounting hole 24 of the base plate 20, and the expansion plug 40 is fixed to the base plate 20. Further, on the back side of the base plate 20, the expansion plug 40 can relatively freely spread outside, so that the expansion plug 40 largely spreads outward from the back surface position of the base plate 20. The expansion plug 40 that greatly expands outside the base plate 20 exerts a pressing force on the base plate 20 in the axial direction toward the head side of the mounting screw 52.

The expansion plug 40 is sandwiched between the head portion of the mounting screw 52 and the expansion portion projecting from the back surface of the base plate 20, and is compressed. As a reaction, the component 50 and the sealing ring 52 are strongly sandwiched and fixed between the head of the mounting screw 52 and the expanding plug 40. The compression of the sealing ring 52 ensures a tight seal between the head of the mounting screw 52 and the component 50. The sealing between the component 50 and the expansion plug 40 is sufficient.

When the expansion plug 40 is compressed by strongly screwing the mounting screw 52, the back surface of the component 50 may come into contact with the surface of the ceramic plate 30. This is a state where the gap G in FIG. 1 has disappeared. Even in such a state, the fixing force of the mounting screw 52 mainly acts between the component 50, the expansion plug 40, and the base plate 20, so that an excessive load is applied to the ceramic plate 30. There is no.

When the fixing of the component 50 with the mounting screw 52 is completed, the component 50 can support the above-mentioned downspout. When a load is applied to the component 50 from the outside, the load is applied to the base plate 20 from the component 50 via the expansion plug 40, so that an excessive load is not applied to the ceramic plate 30.

[0037]

According to the method of mounting a component on a ceramic wall according to the present invention, various types of cracks or cracks can be produced by applying an excessive load to a ceramic plate constituting a finished surface by using an expanding plug. Parts can be securely and firmly attached. As a result, it is now possible to easily attach various components to the ceramic wall, which was previously considered to be extremely difficult to attach to the outer surface after construction, and to reduce the value of the ceramic wall. Enhance
The importance can be expanded.
