Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an AL for construction and construction.
The present invention relates to a construction method for repairing an existing outer wall made of a C member (lightweight cellular concrete) with a new outer wall. More specifically, the connection base material for mounting a new dry wall material is a take-out beam that is fixed directly to the building frame (base material) using the mounting guide, and
The present invention relates to a method for repairing an ALC outer wall that does not damage the outer wall of C and has sufficient attachment strength for a new dry wall material.

[0002]

2. Description of the Related Art Conventionally, the repair of the outer wall using ALC members is a method of removing all the existing old ALC outer wall and forming a new outer wall on the wall base material such as the existing skeleton and furring strip, A new dry wall material is brought into direct contact with the outer wall surface of the ALC, and the dry wall material is fixed by using a fixture such as a concrete anchor.
A construction method in which the LC wall itself is used as a wall base material and repaired is generally known.

[0003]

However, by removing all the old ALC outer walls that have become old as described above,
With the method of forming a new outer wall on the wall base material such as the existing skeleton and furring, there is a problem in increasing the cost for removal and processing of the removed waste material, and there is no outer wall during the construction,
During the construction period, there was a drawback that it was not possible to live in the building, work, or use the inside of the building.

Further, in the method of constructing a new wall material by using the ALC outer wall as it is as a base material for the wall, the old ALC outer wall is cracked, partially dropped, and deteriorated in strength due to frost damage and aging due to its properties. However, there is still a problem in strength in order to impose the main mounting strength of new wall materials using this as a wall foundation, and there is a risk of falling off or peeling off due to external shock such as typhoon or earthquake. It was In addition, the surface of the ALC outer wall has irregularities, and if a new outer wall is constructed as it is, it is difficult to adjust the unevenness due to the irregularities, and irregularities also occur on the raised new wall surface, resulting in poor aesthetics.

[0005]

In order to eliminate such drawbacks, the present invention forms a through hole in an existing ALC outer wall,
Insert a mounting guide having a cylindrical hollow portion into the through hole, fix it to the ALC outer wall, insert the outer member of the connecting base material into the hollow portion of the mounting guide, and form a protruding piece on the outer periphery of the bottom of the outer member. The outer bottom portion with the concave portion formed is attached to the base material, then the attachment guide is removed, the inner member of the connection base material is fastened to the outer member of the connection base material, and the existing ALC outer wall is provided between the through holes. An intermediate through-hole is formed through which a fixing surface facing the thickness of the ALC outer wall is inserted into the intermediate through-hole, and a steadying metal fitting is inserted through the mounting portion. The fixing surface sandwiches the ALC outer wall. Next, we installed a furring strip on the tip and fixing surface of the inner member, and a new dry wall material was fastened to the furring strip, which was a method of repairing the ALC outer wall. Also, the connecting base material expands and contracts. Since it has the ALC outer wall thickness difference and can adjust the unevenness, the appearance of the new dry wall material can be improved, and by using the mounting guide, the existing connection base material can be used. It is possible to attach without touching the ALC outer wall, and to propose a method for repairing the ALC outer wall as a take-out beam construction method that can be repaired without applying any load (load) to the existing ALC outer wall.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a method for repairing an ALC outer wall according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a typical example of the above-mentioned ALC outer wall repaired by a repairing method, and FIG. 2 is an explanatory view showing a cross-sectional view thereof. A is a base for mounting a building frame and an ALC outer wall B. Material, which consists of horizontal members horizontally arranged as shown in the figure, and more specifically, H type steel material, or square steel material (not shown), C type steel material (lip groove type steel material), L type angle It is composed of a steel-framed base material such as a steel material, a grooved steel material, or the like.

Reference numeral B denotes an existing ALC outer wall, which is fixed to a base material A made of H-shaped steel or the like through an angle a and a vertical cover plate b, as shown in FIG. Note that FIG. 2 shows an example of the ALC outer wall B attached by a general insertion muscular construction method at the time of renovation, and there are various other ways to attach the ALC, and the present invention is not limited to this. Not a thing. Further, c is a filler joint material filled in the joint portion of the ALC outer wall B, and further, the ALC outer wall B
The surface of the is coated with a makeup covering member (paint or the like, not shown).

In the present invention, the through hole C and the intermediate through hole C1 are first formed in the existing ALC outer wall B thus formed. As shown in FIG. 3 and FIG. 4, the through hole C and the intermediate through hole C1 are formed on the surface of the ALC outer wall B by using the hole drilling device 1 such as a hole saw on the ALC outer wall B along the arrangement position of the base material A. It is formed from the side. Further, the through hole C functions as a path for inserting a mounting guide F and a connecting base material D, which will be described later, and its shape and size are such that the connecting base material D can be easily filled. It is optional if attached. Of course, the through hole C is formed at a position where the vertical and horizontal stripes are removed.

The pitch of the through-holes C may be any as long as it is within a range satisfying the necessary and sufficient mounting strength (wind pressure strength) for the new dry wall material G, which will be described later. = 600, 900, 1200, 1500m
The m-th position and the pitch L in the vertical direction differ depending on the type of building, but are generally about 3500 mm in height for one floor. By forming the through hole C and the intermediate through hole C1 in the ALC outer wall B, the builder can directly visually check the base material A from the surface side of the ALC outer wall B, and the mounting guide F and the connection described later can be obtained. The base material D is securely attached to the base material A.

Further, the formation pitch of the intermediate through holes C1 is arbitrary as long as it is within a range satisfying the necessary and sufficient mounting strength (wind pressure resistance) for the new dry wall material G described later, for example, the pitch in the horizontal direction. P1 = 300, 450, 600,
About 750 mm, the pitch in the vertical direction varies depending on the type of building, but in general, the height for one floor is 3500 mm
Or about 1750 mm, which is 1/2. Of course, when the dry wall material G can maintain the necessary and sufficient strength by forming the through hole C, the formation of the intermediate through hole C1 is unnecessary. In addition, A
By forming the through hole C and the intermediate through hole C1 in the LC outer wall B, the builder can directly confirm the base material A from the surface side of the ALC outer wall B with the eyes, and the mounting guide F and the connection base material described later can be obtained. The attachment of D to the base material A becomes reliable.

In the through hole C, as shown in FIG.
The hollow portion 3 of the mounting guide F as shown in (a) and (b) is inserted, and the tongue piece 2 of the mounting guide F is fixed to the ALC outer wall B using the fixing tool α. The mounting guide F is shown in Fig. 6.
As shown in (a) and (b), a tubular hollow portion 3 having a hollow inside is integrally attached to a substantially central portion of a flat plate-shaped tongue portion 2. The material of the mounting guide F is made of various metal materials (steel material, aluminum material, stainless material, etc.) and various synthetic resin materials (vinyl chloride material, FRP, polycarbonate, etc.).

Further, a plurality of pilot holes 2a are formed in the vicinity of the outer periphery of the tongue piece 2 of the mounting guide F, and after the hollow portion 3 is inserted into the through hole C, the tongue piece portion is formed on the surface of the ALC outer wall B. The back surface of 2 is abutted, and is fixed by a fixing tool α (hex, tex, screw screw, etc.) through the pilot hole 2a. In this case, the fixing tool α may not be tightened to the end and may be stopped midway so that the attachment guide F can be easily removed (removed) later.

At this time, the center point of the through hole C and the mounting guide F
It is attached with care so that the center points of the hollow portions 2 of the above are substantially the same. With this, the outer member D1 of the connecting base material D described later can be attached to the center portion of the through hole C. The material D1 can be securely attached so that the outer periphery of the material D1 does not come into contact with the through hole C, and no burden (load) is applied to the ALC outer wall B.

Next, as shown in the perspective view of FIG. 7 and the sectional view of FIG. 8, the connecting base material D is placed in the hollow portion 3 of the mounting guide F as shown in FIGS. 9 (a) and 9 (b). External member D
Insert 1. Then, the outer bottom portion 4 in which the protruding piece 4b is formed on the outer periphery of the bottom portion of the outer member D1 and the recessed portion 4a is formed is pushed until the protruding piece 4b comes into contact with the web portion of the base material A, so that a texture driver, a charging driver, or the like can be used. The fixing device α is driven by using the fixing device 5 through the prepared hole 6 formed in the outer bottom portion 4 in advance and fixed to the base material A.

Since the outer member D1 is inserted into and supported by the hollow portion 3 of the mounting guide F, it is not necessary for the builder to support the outer member D1 when fixing, and both hands can be used freely. External member D due to vibration etc. when using the fixed device 5
It is possible to securely fix the fixed position 1 without shifting the position 1. The inner diameter of the hollow portion 3 and the outer member D11
The outer diameter relationship is arbitrary as long as the outer member D1 can be easily inserted into the hollow portion 3 and there is substantially no rattling. Further, since the outer bottom portion 4 is fixed to the base material A through the gap of the recess 4a, the outer bottom portion 4 is fixed in a state where the outer bottom portion 4 is slightly deformed by the fixing force of the fixing device 5 such as a texture driver or a charging driver. The outer bottom portion 4 is fixed in a state of exhibiting a springback effect. For this reason, it is possible to follow a vibration such as an earthquake after construction, exert a constant fixing force, and further firmly fix it without rattling.

As shown in FIGS. 9 (a) and 9 (b), the outer member D1 is a cylindrical body having a bottom, has an outer bottom portion 4, and has a female screw groove 7 formed on the inner peripheral surface on the opening side. Further, one or more prepared holes 6 are formed in the outer bottom portion 4 of the outer member D1. The lower hole 6 functions as a guide hole when the fixture α such as a hex, a tex, a screw screw, etc. is set, and the number thereof is arbitrarily set according to the required mounting strength.

Next, as shown in FIG. 10, when the outer member D1 is attached to the base material A, the fixed attachment guide F is removed this time. This is performed by removing the fixing tool α fixing the mounting guide F and pulling out the hollow portion 3 of the mounting guide F from the through hole C. At this time, in the trace hole formed by removing the fixing tool α that had been fixed, for example, mortar, rock wool, in-situ foaming synthetic resin foam, amorphous sealing material, foam type sealing material, etc. By filling with the filling material 8, it is possible to make up for the lost waterproof property and heat insulating property.

Then, as shown in FIG.
The other inner member D2 constituting the connection base material D as shown in (a) and (b) is screwed into the screw hole of the outer member D1. As shown in FIGS. 11A and 11B, the inner member D2 is a cylindrical body having a bottom and has an inner bottom portion 9.
A male screw groove 10 is formed on the outer peripheral surface of the No. 2.

Further, a tool locking hole 11 is formed in the central portion of the inner bottom portion 9 of the inner member D2, which is shown in FIG.
As shown in FIG. 5, when the inner member D2 is screwed into the outer member D1, it is a hole for inserting the tip of the tool 12 such as a screwdriver, which facilitates the screwing of the inner member D2 and the outer member D1. It will be.

The outer member D1 and the inner member D2 are connected (screwed) to each other such that the surface of the inner bottom portion 9 of the inner member D2 is flush with the direction of the ALC outer wall B, or the inner bottom portion 9 The surface of is screwed in until it slightly protrudes from the surface of the ALC outer wall.

FIG. 12 (a) is a perspective view showing a connecting base material D in which an outer member D1 and an inner member D2 are combined, and FIG.
(B) shows the sectional view. Connection base material D
As described above, is to be inserted into the through hole C formed in the ALC outer wall B, and one end thereof is fixed to the base material A, and the other end is fixed to the furring strip E described later. The material A and the furring strip E, which is a base for mounting the new dry wall material G, are connected to each other to prevent deterioration of the mounting strength of the dry wall material G. In addition, the attachment is performed so that the through hole C and the connection base material D do not come into contact (are not in contact with each other), and the ALC outer wall B is attached without any load (load).

The material of the connecting base material D is various steel materials having excellent strength, iron, stainless steel, aluminum, titanium, various fiber-reinforced synthetic resin materials, and the like. Further, the outer member D1 and the inner member D2 are both cylindrical bodies having a bottom, and both are screw-coupled to each other with the outer bottom portion 4 and the inner bottom portion 9 facing outward.

As described above, since the outer member D1 and the inner member D2 are screw-coupled and integrated as the connecting base material D, the connecting base material D is added with the function of expanding and contracting the length. Even if the thickness of the ALC outer wall material B is different, it is possible to cope with the thickness of the ALC outer wall material B to a certain extent, and it is possible to easily adjust the unevenness of the base material A and the ALC outer wall B.

The intermediate through hole C1 is formed by using the punching device 1 as shown in FIG. 4 as shown in FIG. 13, and as shown in FIGS. 18 (a) to 18 (h) as shown in FIG. Insert the steady rest I like that, and then as shown in FIG.
The ALC outer wall B cut out by the punching device I is filled with the filler 8
Is backfilled and waterproofed by caulking material J. The intermediate through-hole C1 functions as a base to which the vertical furring strip E2 is attached, as shown in FIG. 16, for example.

The steady rest I has a mounting portion 27 and a fixed surface 28.
It is made of a metal material (steel, stainless steel, aluminum, etc.) or the like formed from the fixing surface 29 and the fixing surface 29. The steady rest I is to be attached when the connection base material D alone cannot provide the necessary and sufficient attachment strength (wind pressure resistance) to the new dry wall material G, and only this portion provides strength to the ALC outer wall B. It is a burden. Of course, since it depends on the strength of the ALC outer wall B, an excessive weight load on the ALC outer wall B is avoided.

To explain the construction method further, a long lateral furring edge E1 is fixed to the inner bottom portion 9 of the inner member D2 on the base shown in FIG. 19 in which the connecting base material D and the steady rest I are formed. It is fixed through. The furring strip E is fixed to the tip of the connecting base material D protruding from the surface of the ALC outer wall B by a fixing tool α
It is attached by a fixing means such as the above, and functions as an attachment base of the dry wall material G described later. Also,
Due to its thickness, the furring strip E has a space between the ALC outer wall B and the dry wall material G, and can function as a flow passage for fresh air or the like, and can also be used for corrosion prevention or the like.

As a specific example of the furring strip E, for example, FIG.
As shown in (a) and (b), a flat steel material 15 is attached to the head portion 14 of a hat-shaped steel material 13 by welding to be integrated. Of course, this is an example of the furring strip E,
For example, a square steel material (square pipe), a hat type steel material, a lip groove type steel material, a groove type steel material, a flat type steel material or the like can be used as the furring strip E. As the material thereof, various steel materials having excellent strength, iron plate, stainless plate, aluminum material, wood, laminated material, plastic composite material and the like can be used. Further, the cushion layer 15a shown in FIG.
It is made of rubber and has a length of about 50 mm, and is formed in the intermediate portion between the connecting base material D and the steady rest I to close the gap between the ALC outer wall B and the furring strip E, and to shake the dry wall material G. , To prevent shake. In addition, 18 is a side surface part, 1
Reference numeral 9 is a groove portion, and 20 is a lip portion.

Further, the furring strip E includes a horizontal furring strip E1 extending in the horizontal direction and a vertical furring strip E2 extending in the vertical direction, which will be described later, depending on the type of dry wall material G (vertical type or horizontal type). ,
It can be arbitrarily arranged on the surface of the ALC outer wall B depending on the required furring pitch.

Next, as shown in FIG. 21, the vertical furring strips E2 are fixed to the lateral furring strips E1 arranged in advance at intervals of the pitch P1. The pitch P1 at this time is determined by the necessary furring strip pitch of the dry wall material G to be attached, the required wind pressure resistance strength due to the ground clearance, and the like, for example, 3
00, 450, 600, 900, 1200, 1500,
2000 mm, etc.

The overlapping portions of the horizontal furring strip E1 and the vertical furring strip E2 are on the same plane so that the distance between the ALC outer wall B and the dry wall material G does not become long (so-called dandruff does not occur). It is preferable to connect them at the top, for example, FIG. 22 (a).
It is preferable to carry out as shown in FIG. 23 by using the connecting fitting H1 as described above, or as shown in FIG. 24 by using the connecting fitting H2 as shown in FIG.

That is, the connecting fitting H shown in FIG.
Reference numeral 1 is an angle piece shape formed by bending the connecting tongue pieces 16 to each other in an L shape, and each connecting tongue piece 16 is formed with a pilot hole 17 serving as a positioning guide for the fixing tool α.

As shown in FIG. 23, the connecting metal fitting H1 is for connecting the horizontal furring strip E1 and the vertical furring strip E2 from the side surface portion 18 thereof with the fixing tool α, and fixing and connecting them. Then, using a total of four connecting metal fittings H1 on the top, bottom, left and right,
The furring edges E are firmly connected to each other.

As shown in FIG. 24, the connecting metal fitting H2 is inserted so as to sandwich the side wall portions 18 of the vertical furring strip E2, and one side wall portion 18 of the horizontal furring strip E1 and two vertical furring strips E2 are inserted.
The three side surfaces 18 are fixed at three points. The lip portion 20 is a portion for fixing the dry wall material G. The lateral furring strips E1 and the vertical furring strips E2 are connected to each other by driving the side surface portions 18 with the fixtures α, and the lateral furring strips E1 are connected.
By not hitting the fixing tool α to the lip portion 20, the dandruff caused by the head of the fixing tool α can be eliminated, and the attachment of the dry wall material G is prevented. Further, by inserting the connecting fitting H2 into the horizontal furring strip E1, it is possible to eliminate the unevenness of the horizontal furring strip E1 and the vertical furring strip E2.

Finally, as shown in FIG. 1, the dry wall material G is attached to the vertical furring strip E2 via the fixture α. The new dry wall material G covers the surface of the old ALC outer wall B to form a new wall surface, and mainly functions as a decorative material, a waterproof material, a heat insulating material, a fireproof material, and a fireproof material. In order not to put a burden on the existing base material A, for example, lightweight metal panels, metal siding materials, various ceramic siding materials, etc. as shown in FIG. 25 are preferable.

That is, the dry wall material G shown in FIG. 25 is composed of a sandwich plate material in which a core material 23 is sandwiched between a front surface material 21 and a rear surface material 22.

When the front surface material 21 and the rear surface material 22 are made of synthetic resin plates, for example, a vinyl chloride resin, a polycarbonate resin or the like is formed into a predetermined shape by extrusion molding, press molding, roll molding or the like. Of course, a material in which these metal plates and synthetic resin plates are laminated and composited may be used.

Further, especially the backing material 22 is aluminum vapor-deposited paper, asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, hydroxide. Aluminum paper,
It can also be formed from one kind of glass fiber nonwoven fabric or a laminate of two or more kinds, or a sheet-like material that has been waterproofed and flame-retarded.

The core material 23 mainly functions as a heat insulating material, a fireproof material and a bulking material of the dry type wall material G, and is made of polyurethane,
Synthetic resins such as polyisocyanurate, phenol, vinyl chloride, polyethylene, polystyrene, urea and their foams, or inorganic materials such as calcium silicate, calcium carbonate, aluminum hydroxide and their foams, or glass fiber, ceramic fiber, A fibrous mat-like material such as rock wool and asbestos, an inorganic board such as a gypsum board, a sheathing board, a wood wool cement board, a calcium silicate board, and the like.

Further, the core material 23 is integrated with the front surface material 21 and the back surface material 22 by utilizing its self-adhesiveness when the core material 23 is a synthetic resin foam or otherwise. It is laminated and separately sandwiched by an adhesive (not shown).

Further, FIG. 25 shows a general horizontal metal siding having a male type connecting portion 24 formed at one end of the dry type wall material G and a female type connecting portion 25 formed at the other side end thereof. It is an example showing a material. In the figure, a single piece of soft sealing material 26 is interposed in the female type connecting portion 25 to improve the waterproofness of the joint portion.

Further, the installation of the dry type wall material G is as shown in FIG.
As shown in FIG. 2, the male connecting portion 24 is fixed to the vertical furring strip E2 by using a fixing tool α such as a tapping screw, a text screw, a self-drilling screw screw, and the male connecting portion 24 and the female connecting portion 25. It is connected and attached by male and female fitting with. Of course, although not shown,
Various new materials such as a draining material, a starter material, a tongue material, a projecting corner material, an entering corner material, an opening member, a joint member, and a sealing material are constructed as necessary to form a new outer wall surface.
