Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to various types of structures such as civil engineering and marine concrete structures such as tunnels, piers, bridge girders, and slopes, building concrete structures such as buildings and condominiums, and exterior walls of general wooden houses. In addition, the present invention relates to a mortar-like incombustible material construction method for constructing a mortar-like incombustible material on a structure constructed by disposing panels on a construction surface, a panel used in the method, and a noncombustible layer structure.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing various structures, a laminate (a board such as a plywood board) in which a reinforcing fiber sheet such as a carbon fiber sheet or an aramid fiber sheet is impregnated and fixed in plural layers with an adhesive such as an epoxy resin. It is known that a panel made of a material obtained by impregnating and fixing a reinforcing fiber sheet or a material obtained by impregnating and fixing only a reinforcing fiber sheet with the fiber directions alternately orthogonal to each other is disposed on a construction surface.

[0003] Such a panel is fixedly mounted on a frame member (a pillar, a horizontal rail, or the like) with an adhesive or the like to construct a wall surface or a ceiling surface of a structure under construction, for example, or an existing panel is provided. It will be installed on the wall and ceiling as a repair work for the structure.

[0004] Incidentally, since there is a risk that the panel will spread fire due to a fire, the surface of the structure must be covered with a non-combustible layer depending on the type of the structure to be constructed. That is, in the method of arranging the panels, the mortar-like incombustible material may have to be installed from above the arranged panels.

[0005] As such a mortar-like incombustible material, mortar is applicable. As other mortar-like incombustible materials, asbestos, rock wool, charcoal (calcium carbonate), plaster, gypsum material, expandable gypsum material, straw earth, Slurry type etc. are mentioned. As a method of constructing such a mortar-like incombustible material, a mortar-like incombustible material (for example,
Mortar) may be laid by means of wet or dry spraying or plastering, but there is a risk that the mortar-like incombustible material layer may collapse (even a thin layer cannot be constructed because of the risk of collapse). Generally, a reinforcing material such as a lath is buried in the mortar-like incombustible layer.

That is, conventionally, as a method of applying a mortar-like incombustible material from the top of a panel, a locking member such as a nail or an anchor is driven into the surface of the panel to fix a reinforcing material such as a lath. After locking the reinforcing material to the locking member,
A mortar-like incombustible material is laid from above by spraying or the like, and a noncombustible layer is constructed.

[0007]

However, in such a construction method, after the panel is provided, the locking member must be driven into the panel, and thus the operation is complicated. is there.

Further, when the locking member is driven into the panel, the panel is damaged and the strength of the panel is reduced. In particular, in the case of a panel formed of a reinforcing fiber sheet, it is not preferable because the reinforcing fibers constituting the reinforcing fiber sheet are cut by driving the locking member.

[0009] The present invention has been made in view of the above problems, and a simple mortar-like non-combustible layer is easily applied to a structure constructed by disposing a panel on a construction surface from above the panel. It is a first object to provide a method for constructing a mortar-like incombustible material that can be performed. It is a second object of the present invention to provide a method for constructing a mortar-like incombustible material that can easily construct a strong mortar-like incombustible layer from above the panel without reducing the strength of the panel.

A third object is to provide a panel suitable for use in the above-mentioned construction method. It is a fourth object of the present invention to provide a non-combustible layer structure in which a mortar-like non-combustible layer constructed from above a panel is unlikely to collapse and the strength of the panel is maintained.

[0011]

Means for Solving the Problems The present invention has been made to solve the above problems, and a first means for solving the problems is a method for applying a mortar-like incombustible material,
After disposing a panel 15 on which a locking portion 3 capable of locking a reinforcing member 18 such as a lath is projected on a construction surface 14,
Of the mortar-like incombustible material from above the reinforcing member 18 by locking the reinforcing material 18 to the locking portion 3 protruding from the surface of the mortar.

According to the above construction method, since the panel 15 on which the locking portion 3 capable of locking the reinforcing member 18 such as a lath or the like is used in advance is used, after disposing the panel 15 on the construction surface 14, There is no need to attach a locking member to lock a reinforcing member such as a lath.

Furthermore, the panel 15 is provided with a laminate of reinforcing fiber sheet 2, such as carbon fiber sheets and the locking portion 3, provided so as not to cut the reinforcing fiber sheet 2 fibers Runode, The strength of the panel 15 itself does not decrease .

[0014] Incidentally, as claimed in claim 2, wherein, if necessary, after disposing the panel 15, adjacent panels 15
If the seam 16 between the panels 15 is closed by adhering a reinforcing fiber sheet 2 such as a carbon fiber sheet between them,
Are integrated.

As a second means for solving the above-mentioned problems, a locking portion 3 capable of locking a reinforcing member 18 such as a lath on the surface of the panel main body 1 provided on the construction surface 14 is provided. Is to protrude.

If such a panel is arranged on the construction surface 14,
The locking portion 3 capable of locking the reinforcing member 18 such as a lath protrudes from the surface of the panel, that is, the surface of the construction surface, and thereafter, the reinforcing member 18 such as a lath can be easily attached.

Furthermore, the panel body 1, comprises a laminate of reinforcing fiber sheet 2, such as carbon fiber sheets and the locking portion 3, provided so as not to cut the reinforcing fiber sheet 2 fibers Runode , there is no possibility of reducing the strength of the panel 15 itself.

As means for projecting the locking portion 3 from the panel main body 1, for example, the support body 1 having the locking portion 3 which can lock a reinforcing material such as a lath on one surface side is provided. What is necessary is just to adhere to the surface of the panel main body 1 with an adhesive etc.

In addition, if the supporting member main body 5 is provided with an insertion engaging portion 6 that can be inserted into the reinforcing fiber sheet 2 of the panel main body 1 on the other surface side of the supporting member main body 5, the insertion engaging The portion 6 can be inserted between the fibers of the reinforcing fiber sheet 2 constituting the panel main body 1, so that the locking portions 3 project from the panel main body 1 so as not to cut the fibers of the reinforcing fiber sheet 2. be able to.

As a third means for solving the above-mentioned problems, a panel 15 provided on a construction surface 14 and having a laminate of a reinforcing fiber sheet 2 such as a carbon fiber sheet, A locking portion 3 provided on the surface of the panel 15 so as not to cut the fibers of the reinforcing fiber sheet 2;
It is provided with a reinforcing member 18 locked by the locking portion 3 and a mortar-like non-combustible layer 19 laid on the reinforcing member 18.

With this non-combustible layer structure, the locking portion 3 for locking the reinforcing member 18 such as a lath is provided so as not to cut the fibers of the reinforcing fiber sheet 2 constituting the panel 15. Since the strength of the mortar 15 does not decrease and the reinforcing material 18 is buried in the mortar layer 19, the mortar adheres to the reinforcing material 18, so that the mortar layer 19 hardly peels off. Therefore, the mortar-like incombustible layer 19 can be formed thickly. For example, even if the mortar-like incombustible layer 19 is applied to the inner upper surface of a structure such as a tunnel, the mortar-like incombustible material is
There is no risk of falling.

[0022] Incidentally, as claimed in claim 5, wherein the mortar-shaped incombustible layer 19, if it is constituted by a resin mortar or fibers mixed mortar is more preferable because the strength is increased.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment according to the present invention will be described below with reference to the drawings. First, the panel according to the present invention will be described.

In FIG. 1, reference numeral 1 denotes a panel main body having a laminate in which a reinforcing fiber sheet 2 is laminated in a plurality of layers (for example, four layers as shown). Examples of the reinforcing fiber sheet 2 include an organic fiber sheet and an inorganic fiber sheet such as a carbon fiber sheet, an aramid fiber sheet, a nylon fiber sheet, a glass fiber sheet, a polyarylate fiber sheet, and a polyolefin fiber sheet, and a composite fiber sheet thereof. Is done.

The reinforcing fiber sheet 2 is formed by laminating a second layer of reinforcing fiber sheet 2 in a direction substantially orthogonal to the fiber direction of the first layer. Are stacked so as to be substantially orthogonal. As described above, since the layers are laminated so that the fiber directions of the layers are substantially orthogonal to each other, the strength of the panel is improved, which is preferable.
The layers need not necessarily be laminated such that the fiber directions of the layers are substantially orthogonal.

The reinforcing fiber sheet 2 is firmly fixed and integrated by impregnating an adhesive such as an epoxy resin.

The shape of the panel body 1 is not limited to a flat plate, but may be formed in various shapes such as a substantially cylindrical shape, a substantially semicircular gutter shape, and a substantially square gutter shape as shown in FIG. That is, it is formed in an appropriate shape along the shape of the construction surface, and for example, if it is a substantially square gutter shape as shown in FIG. 1, it may be used when arranging panels on the construction surface such as a square pillar. .

On the front surface 1a of the panel body 1, a plurality of locking portions 3 capable of locking a reinforcing material such as a lath are provided at predetermined intervals so as to protrude (in the drawing, two locking portions are provided). Part 3 only).

The locking portion 3 is provided so as not to cut the reinforcing fibers constituting the panel body 1.

More specifically, as shown in FIGS. 2 and 3, for example, the locking portion 3 is formed of a band protruding from one surface 5a of the support body 5 fixed to the panel body 1. As shown in FIGS. 2 and 3, the support body 5 is made of a stainless plate-like body, and has an insertion engagement portion 6 on the other surface 5b side.
Are provided, and four holes 9 (corresponding to the penetrating portions into which the adhesive enters) are formed at regular intervals near the periphery of the support body 5.

The support body 5 and the locking portion 3 are not limited to stainless steel, but may be other materials such as iron. However,
It is preferable that the locking portion 3 is formed of a material having excellent insulating properties, such as stainless steel, because it has an effect of preventing electrolytic corrosion.

More specifically, the support body 5 has a circular outer shape, and is formed of a thin plate-like body that can be bent by hand.

At the center of the support body 5, FIG.
As shown in FIG. 5, three elongated substantially U-shaped notches 7 are cut in three places, and a part surrounded by the notches 7 (a part 8 partitioned by one notch 7) is formed. , By bending the support body 5 approximately 90 degrees to the one surface 5a side.
a side, and the protruding portion 8
However, the belt-shaped locking portion 3 capable of locking a reinforcing material such as a lath (see FIGS. 2B and 3). In addition, one or more (for example, two as shown) protrusions are provided on one surface 5a of the support body 5.

On the other hand, a portion surrounded by the cut portion 7 (a portion 10 partitioned by another cut portion 7) is slightly bent to the other surface 5b side of the support body 5 so that the other surface 5b side is formed. From the projecting portion 1
0 is the band-shaped insertion engaging portion 6 that can be inserted into the reinforcing fiber sheet (see FIGS. 2B and 3).

The tip 6a of the insertion engaging portion 6 is formed in a pointed shape so that it can be easily inserted into the reinforcing fiber sheet. In addition, although one insertion engagement portion 6 is protruded from the other surface 5b of the support tool main body 5, a plurality of insertion engagement portions 6 may be provided.

The insertion engaging portion 6 has its base end 6b stepped so as to protrude slightly from the other surface 5b of the support body 5, and has a slight angle with respect to the other surface 5b of the support body 5. (e.g., about 5 degrees), so that the insertion engaging portion 6 projects substantially parallel to the other surface 5b of the support body 5 and slightly away from the other surface 5b. Has been established.

As shown in FIG. 4, the support body 5 has the distal end 6a of the insertion engagement portion 6 inserted between the fibers of the reinforcing fiber sheet 2 of the panel body 1, and the other surface 5b of the support body 5 as shown in FIG. It is brought into contact with the surface of the reinforcing fiber sheet 2 and is firmly fixed with an adhesive 11 such as an epoxy resin (an adhesive that impregnates and fixes the reinforcing fiber sheet 2 may be used).

Specifically, the insertion engaging portion 3 of the support body 5
Is substantially parallel to and slightly protruded from the other surface 5b of the support body 5, so that when inserted into the reinforcing fiber sheet 2, the other surface 5b of the support body 5 The support body 5 is pressed against the surface of the reinforcing fiber sheet 2, and the other surface 5 b side is pressed against the surface of the reinforcing fiber sheet 2.

By the pressing, the adhesive 11 before being cured becomes
The hole 9 of the support body 5 and the punched portion of the cutout portion 7 (the through hole formed in the support body 5 after the insertion engagement portion 6 and the locking portion 3 are bent) enter the excess adhesive 11. Support body 5
To the one surface 2a side.

Therefore, after the adhesive 11 that has entered the holes 9 and the like of the support body 5 is hardened, the adhesive 11 acts like a nail, and the support body 5 is connected to the reinforcing fiber sheet 2.
Can be firmly fixed on the surface.

By fixing the other surface 5b of the support main body 5 to the panel main body 1 in this manner, the locking portion 3 projects from the surface of the panel main body 1. Further, when fixing the support member main body 5 so that the locking portion 3 is protruded, since the insertion engagement portion 6 of the support member main body 5 is inserted between the fibers of the reinforcing fiber sheet 2, the reinforcing fiber sheet 2 is not cut, and the support main body 5 is hooked on the reinforcing fiber sheet 2 by the insertion engaging portion 6, so that the support main body 5 is structurally supported not only by the adhesive 11 but also structurally. 5 can be fixed to the reinforcing fiber sheet 2.

Further, after the insertion engaging portion 6 of the support body 5 is inserted, if the adhesive 11 is hardened, it is firmly fixed if the adhesive 11 is hardened. It can be protruded .

In particular, when the support member body 5 is fixed to project the locking portion 3, there is an advantage that an adhesive for impregnating and fixing the reinforcing fiber sheet 2 of the panel body 1 can be used. That is, the reinforcing fiber sheet 2 constituting the surface layer of the panel body 1
If the support tool body 5 is inserted into the reinforcing fiber sheet 2 before the adhesive used for laminating the reinforcing fibers is cured, an adhesive for impregnating and fixing the reinforcing fiber sheet 2 of the panel body 1 can be used.

In the panel having the above-described structure, the locking portion 3 capable of supporting a reinforcing material such as a lath is provided so as to protrude. A stiffener can be locked. Further, since the locking portion 3 is provided on the panel main body 1 so as not to cut the reinforcing fibers of the reinforcing fiber sheet 2, there is no possibility that the strength of the panel is reduced.

Next, a method for applying the mortar-like incombustible material using the panel 15 and the incombustible layer structure will be described below.

As shown in FIG. 5, a panel 15 is provided on the construction surface 14 of the structure. As a means for fixing the panel 15 to the construction surface 14, the panel 15 may be fixed to the construction surface 14 with an adhesive, or may be attached to the construction surface 14 using a building hardware such as an anchor or a nail. Arranged on surface 14.

In FIG. 5, a concrete structure is exemplified as the construction surface 14, but the construction surface 14 may be, for example, a frame member for constructing a wall surface or a ceiling surface of the structure. Wooden pillars or horizontal crossbars, etc.)
Further, the construction surface 14 may be a new (under construction) structure or an existing structure.

If necessary, adjacent panels 1
The seam (gap) 16 between 5 and 15 is reinforced with the fiber reinforced sheet 2. Specifically, a primer is applied to the surface of the panel 15 to secure the adhesive strength, and after drying, a room temperature curable resin that cures at room temperature, for example, is applied as an adhesive on the primer. A reinforcing fiber sheet 2 such as a carbon fiber sheet is attached thereon.

Adhering the reinforcing fiber sheet 2 to the joint 16 between the panels 15 as described above is preferable because the panels 15 are integrated. In particular, when the reinforcing fiber sheet 2 to be bonded to the seam 16 is bonded so that the fiber direction of the reinforcing fiber sheet 2 is substantially perpendicular to the fiber direction of the reinforcing fiber sheet 2 on the surface of the panel 15, the panels 15 are strongly connected to each other. It is more preferable because it is integrated into Note that a finishing resin may be applied from above the reinforcing fiber sheet 2, and the finishing resin preferably has high adhesiveness to mortar.

Next, as shown in FIG. 6, a reinforcing member 18 such as a lath is locked to the locking portion 3 projecting from the panel 15.
More specifically, as shown in FIG.
Of the locking portions 3, the tip 3 a side of one locking portion 3 is bent around the reinforcing member 18, and the tip 3 a side of the other locking portion 3 is bent around the reinforcing member 18 from the other. That is, two (plural) locking portions 3 are wound around the reinforcing member 18.
When the engaging portion 3 is wound around the reinforcing member 18 as described above, the reinforcing member 18 is extremely firmly fixed, and thus it is preferable that the reinforcing member 18 does not accidentally fall off.

Finally, mortar is sprayed or laid as a mortar-like incombustible material over the reinforcing material 18 by means such as spraying or plastering iron so as to cover the reinforcing material 18.
(Mortar-like noncombustible layer 19) is applied.

The mortar is cement mortar,
A conventionally known mortar such as a resin mortar, a resin mortar, and a fiber mortar may be used.

When the mortar is laid, the procedure is not limited to simply laying the cement mortar on the reinforcing member 18. Reinforcing material 1
Spraying a primer on the mortar, then laying resin mortar, fiber mixing mortar or cement mortar,. The mortar is sprayed on the reinforcing material 18 by a procedure such as spraying a primer on the reinforcing material 18, then spraying a cationic cement mortar for roughening purposes, and laying a resin mortar, a fiber mixed mortar or a cement mortar from above. May be covered. By using a resin mortar, a fiber-mixed mortar, or the like, the mortar itself becomes strong.

Further, as the reinforcing member 18, other than the lath, for example, a net-shaped or sheet-shaped molded product of a fiber-reinforced plastic such as carbon fiber, glass fiber, and vinylon fiber may be used.

The panel 15 provided with the laminated body of the reinforcing fiber sheet 2 in this manner, and the locking portion 3 provided on the surface of the panel 15 so as not to cut the fiber of the reinforcing fiber sheet 2
Thus, a mortar layer structure including the reinforcing member 18 locked by the locking portion 3 and the mortar layer 19 laid on the reinforcing member 18 is constructed.

According to the method for applying a mortar-like incombustible material according to the present invention, after the panel 15 is disposed on the installation surface 14, a locking member for locking the reinforcing material is attached to the panel as in the conventional case. Work becomes unnecessary. Therefore, complicated work is omitted, and mortar can be easily constructed.

Further, according to the above-mentioned construction method, the reinforcing member 18 is firmly attached to the panel 15 via the locking portion 3 and the mortar is fixed to the reinforcing member 18. 19, the mortar is extremely difficult to peel off, and thus the mortar layer 19 is thick (for example, 30 mm).
Above) Can be constructed. Further, since it is difficult to peel off, the mortar layer 19 is also applied to the ceiling surface such as the inner upper surface of the tunnel.
Can be constructed.

Further, since the locking portion 3 is provided so as not to cut the reinforcing fiber sheet 2, the effect of the reinforcing fiber sheet 2 is not reduced.

In the above embodiment, the panel body 1
Is made of a laminate of the reinforcing fiber sheet 2, but the panel body 1 is not necessarily limited to the laminate of the reinforcing fiber sheet 2. For example, the reinforcing fiber sheet 2 (or reinforcing material) may be formed on a plywood, a synthetic resin molded board, a metal plate, or the like. The panel main body 1 is composed of a panel main body 1 to which a laminated body of the fiber sheet 2 is adhered (that is, a panel main body 1 provided with a laminated body of the reinforcing fiber sheet 2), a simple plywood, a synthetic resin board, a metal plate, or the like. It may be.

Further, in the above embodiment, the locking portion 3
Is fixed to the panel main body 1 so as to protrude from the surface of the panel main body 1, but the locking portion 3 is not necessarily limited to such a configuration. Alternatively, a wire member such as a hook-shaped member and a number wire may be driven in to project from the surface of the panel body 1. Further, in the above embodiment, the locking portion 3 is formed in a band shape, but the locking portion 3 is not necessarily limited to a band shape. In short, it is sufficient that the locking portion 3 that can lock the reinforcing member 18 such as a lath protrudes from the surface of the panel body 1.

However, as in the above embodiment, it is preferable to provide the locking portion 3 so as not to cut the fiber of the reinforcing fiber sheet 2 of the panel body 1, and to provide the locking portion 3 so as not to cut the fiber. It is preferable to use the adhesive 11 because the panel 15 can be easily manufactured.

Further, in the above embodiment, the reinforcing material 1
Mortar is laid as a mortar-like incombustible material from above 8, but the mortar-like incombustible material is not limited to mortar, but asbestos, rock wool, charcoal (calcium carbonate), plaster, gypsum, foam A gypsum material, straw soil, a slurry type, or the like may be used.

[0063]
