Description

The present invention relates to ceramic siding of buildings [formed into a plate shape using cementitious raw materials and fibrous raw materials as main raw materials, cured and hardened] or cellular concrete [cellular concrete such as ALC, lightweight cellular concrete, etc. including. The present invention relates to a method for repairing an outer wall for repairing an existing outer wall surface made of a new dry wall material, a body edge support member for a building outer wall, and a method for fixing a body edge for a building outer wall.
More specifically, the body edge support member for the building outer wall for attaching the new dry wall material is fixed to the bracket taken out from the building frame (the steel frame of the existing building), and the new dry wall material is attached to the outer wall. The present invention relates to the renovation of the outer wall in which a new dry wall material having sufficient mounting strength is installed without placing any burden on the existing outer wall by adopting a structure that is fixed to the body edge.

  Conventionally, after renovating the outer wall, all the existing outer walls are removed, and then a new outer wall is formed by using the existing base material such as the frame and the trunk edge, or a new dry wall material directly on the outer wall surface. There is generally known a method of repairing a wall using a fixing tool such as a concrete anchor and using the outer wall itself as a wall base material.

  As described above, with the method of removing all the old exterior walls and forming a new exterior wall on the existing base material such as the frame or trunk edge, the cost for removing existing walls is increased or removed. In addition, there is a problem in the disposal of the waste material, and the building has no outer wall during the construction, so that it is impossible to use the interior of the building, for example, it becomes impossible to live in the building during the construction period.

  In addition, in the method of constructing new wall materials using the existing outer walls as they are as the base material for the walls, many of the outer walls that have become old have been cracked, partially dropped or deteriorated due to frost damage or changes over time. The use of as a wall base has a problem in the mounting strength of a new wall material that has been attached, and it has a risk of falling off or peeling off due to an external impact such as a typhoon or earthquake. Furthermore, there are irregularities on the surface of the normal outer wall, and if the 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 new wall surface formed based on it, causing cracks and It was inevitable that the aesthetics would be inferior.

  Recently, a support bracket formed by an outer member that has a cylindrical shape from a cored hole that penetrates the outer wall, has a fixing bottom at one end and a threaded portion at the other end, and an inner member that can be screwed into the existing building. An outer wall repairing method using a repairing device for fixing a vertical trunk edge or a horizontal trunk edge to the other end of the support metal fitting and attaching an exterior material to the vertical trunk edge or the horizontal trunk edge has been proposed. Proposals have been made for two-piece support fittings (Patent Document 1 and Patent Document 2) in which the outer member and the inner member of the repair device are screwed together so that they can be expanded and contracted in the length direction and the entire length can be adjusted. ing.

  When using this support bracket, to fix the exterior material without damaging it, by directly fixing the support bracket to the building frame without applying a load to the existing exterior material to attach the exterior material. There is an advantage that can be. However, these proposed support brackets can adjust the length between the cylindrical fixing bottom mounting portion and the barrel fixing base mounting portion by rotating the inner member. A screw is provided between the inner member and the inner member, and the distance is adjusted by rotating the screw. Not only is the production complicated and expensive, but also the distance adjustment operation is troublesome. .

  In the present invention, a cored hole is formed in an existing outer wall, and a fixed bracket is used as a trunk support member for a building outer wall from the surface of the building outer wall to the cored hole for fixing an exterior material. After fixing to the web, the body edge is placed on the body edge support material of the bracket or fixed, or the slide type bracket is inserted, and the mounting part of the slide type bracket is fixed to the web of the existing building frame, An adjuster is mounted on a horizontal support member extending horizontally of the slide type bracket, the position is adjusted and fixed, a barrel edge is fixed to the other end of the adjuster, and a new dry wall material is fixed to the barrel edge. When there is an exterior material mounting part on the building frame, one end of the integrated bracket for fixing the trunk edge is fixed to the mounting part, and the other end is a square steel pipe or lip groove steel provided on the outer edge of the exterior casing. It was found that the barrel edge can be easily fixed by fixing a dry wall material to the barrel edge after being fixed to the barrel edge.

When according to the method of the present invention,
(A) Since it is not necessary to dismantle the outer wall of an existing building, the construction man-hours can be omitted, the construction period can be greatly shortened, and there is no hindrance to residence and use during construction.
(B) Since a new outer wall is formed on the outer wall of an existing building, construction is easy and cost can be saved.
(C) By forming the core hole in the outer wall, the frame of the existing building can be confirmed directly from the surface side, and the bracket can be securely attached to the frame. (D) The building edge support member for the outer wall of the building is structurally attached and fixed directly to the frame of the existing building, so the existing outer wall can be refurbished without any load (load), and a new dry wall material can be installed. It has the advantage of sufficient strength.

The trunk support member for building outer wall according to the present invention is not only simple and inexpensive, but also easy to construct, and the length between the mounting part of the slide bracket and the fixing part of the trunk edge can be easily adjusted. Very advantageous. Further, when the outer wall repairing method of the present invention is used, there are features and effects such as easy adjustment of unevenness, reliable strength, and ease of construction.
In particular, when a fixed bracket is used as the body edge support member for the building outer wall, the bracket itself is also inexpensive, and since it can be easily attached to the body edge, the longest fixed bracket is prepared. It is also an effective means to easily adjust the installation of the trunk edge by cutting the extra length after placing the trunk edge.

  For existing buildings, a building frame [a material called mainly H-shaped steel or I-shaped steel is used in consideration of building strength, cost, and the like. In the present invention, the building frame is referred to as a steel frame, the central member of the H-shaped steel is referred to as a “web”, and the portions extending horizontally above and below the web are referred to as “flange”. ], The lower floors are usually made of thick, large steel frames, and smaller steel frames are usually used as they go to the upper floors. In this H-shaped steel, the thickness of a large steel frame is usually increased, and not only the web but also the flange is increased in size. For this reason, naturally the distance from the web of a housing or a flange edge part to the trunk edge to install differs.

Conventionally, a steel material having a shape called a “K steel” having a cross section as shown in FIG. 8 is generally used for the barrel edge. However, since it is often insufficient in rigidity, a square steel pipe (mainly It is preferred to use a lateral waist edge) or a lip groove steel (mainly a longitudinal waist edge). Since these are higher in rigidity than “K steel”, when the same outer diameter is used, a longer one can be used, and there is no problem even if a large reinforcing interval is taken.
These horizontal trunk edges are used without cutting as much as possible, but the vertical trunk edges are cut to a length connecting between the horizontal trunk edges, and the thickness of the trunk edges is adjusted by joining them using a barrel edge joint metal fitting. It is usually done to halve.

Hereinafter, an embodiment of the outer wall repair structure according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram showing a typical example of an outer wall repair structure using a fixed bracket. In FIG. 1, H-shaped steel is usually used as a building frame (1). When renovating the outer wall of the building, the core hole (3) formed in the outer wall (2) uses a device such as a core drill or a hole saw at a constant pitch on the outer wall (2) along the position of the housing (1). And formed from the surface side of the outer wall 2. The size of the core hole (3) requires a shape and size sufficient to attach, adjust and fix the bracket to the housing (1). The above size is not necessary.

The fixing part (41) of the fixed bracket (40) is fixed to the housing (1) by welding, tapping screws, tex screws, self-drilling screw screws, etc. (hereinafter these screwing methods are collectively referred to as “screwing”) Say). After fixing the mounting portion (41) of the fixed bracket (40) to the housing (1), the trunk edge (6) is fixed to the other end side of the trunk edge support member (45). Preferably, the trunk edge (6) is placed on the trunk edge support (45) and fixed by welding or screwing.
The fixed bracket (40) includes a trunk edge support member (45) and an attachment portion (41) made of an iron plate at one end thereof. As this trunk edge support material (45), a commercially available angle, C-type channel or square pipe is usually used, and an attachment part (41) made of an iron plate is joined to one end thereof by welding or the like, The length of the angle or the like may be manufactured in accordance with the distance between the casing (1) and the trunk edge (6), but a length having the longest distance may be prepared in advance. Then, it may be constructed by cutting and adjusting the length at the factory or the like according to the site, or the portion coming out from the surface of the trunk edge (6) after being installed at the site may be cut.

The mounting location to the housing (1) is not particularly limited when the strength is sufficient, but when the building housing (1) is H-shaped steel or I-shaped steel, it is preferable to attach it to the web for ease of construction. . When the mounting position on the housing hits the connection part of H-shaped steel or I-shaped steel, it is difficult to directly mount on the web, so it is mounted on the upper part of the flange.
Installation is possible if welding is possible, but it is highly possible that flammable materials such as wood, synthetic resin panels, and heat insulating materials are used inside the building, and it is not recommended as a fixing method for the fixed bracket (40). .

  The method of attaching to the trunk edge (6) may be directly attached to the trunk edge (6) by welding or screwing, but is not particularly limited. Even if the barrel edge attachment portion on the opposite side of the bracket attachment portion is fixed to the horizontal trunk edge (61) or the vertical trunk edge (62) using a hardware (7) for bonding the trunk edge as shown in FIG. good. Note that FIG. 1 shows the attachment of the outer wall 8 for lateral stretching. There are various other ways of attaching the dry wall material, and the present invention is not limited to this.

  The horizontal trunk edge (61) [vertical trunk edge (62)] fixed to the exterior material fixing surface with the fixed bracket (40) is the vertical trunk edge (62) [horizontal trunk edge (61)] and trunk edge. The trunk edge (6) is assembled using the joint hardware (7). In this case, in order to reduce the distance between the new dry wall material (8) and the outer wall material (2) of the existing building, it is necessary to reduce the thickness of the entire body edge (6). It is preferable to prevent the thickness from being increased by bonding the cut pieces at the intervals between the trunk edges (61) using the trunk edge fitting (7). In this case, if the flat portions such as the fixed bracket (40) and the body edge fitting (7) are bent for reinforcement, the rigidity against deformation can be greatly improved.

In addition, when the space | interval of the surface of a building exterior material (2) and a housing (1) was not constant, it adjusted to the length of the attachment part of a bracket and the fixing part of a trunk edge instead of a fixed bracket. It is also possible to use a slide type bracket made up of a slide type bracket (A) and an adjuster (B) that are easy to handle.
FIG. 5 shows a typical example of the repair structure of the outer wall using the slide type bracket, and FIG. 6 is a view for explaining the slide type bracket and the adjuster.
Since this slide type bracket is expensive and requires extra man-hours for construction, a fixed type bracket that matches the size of the steel frame of the building frame (for example, one example is shown in FIG. It is preferable that the body edge is fixed in advance by preparing a distance, which is adjusted according to the length of the body edge support (45).

  When renovating the building outer wall using the above slide type bracket, the core punching hole (3) formed in the outer wall (2) is arranged at a constant pitch along the arrangement position of the housing (1), such as a core drill or a hole saw. It forms from the surface side of an outer wall (2) using an apparatus. The size of the core hole (3) requires a shape and size sufficient to attach the bracket (A) of the slide type bracket to the web (11) of the housing (1) and adjust and fix the position of the adjuster. If the size is such that this operation can be performed easily and reliably, no further size is required.

  As an example, the bracket (A) of the slide type bracket has a mounting portion (A1) at one end of the bracket (A), and the bracket (A) is securely fixed to the housing (1) at this portion. Although FIG. 5 shows the mounting portion (A1) having a bolt hole, a normal fixing method such as welding, a bolt nut, or a tapping screw may be used, and the fixing method to the housing (1) can be fixed securely. If so, the method is free. A horizontal support member (A3) provided with a loose hole (A4) extending horizontally at right angles to the mounting portion (A1) and capable of fixing the position of the adjuster (B) at an arbitrary position is provided. In order to increase the bending strength of the horizontal support member (A3), it is preferable to provide a reinforcing bent portion (A5) in which a slight width at both end portions thereof is bent at a substantially right angle. It is also a preferable method to provide a reinforcing plate (A2) in order to ensure the strength between the attachment portion (A1) and the horizontal support member (A3).

  The adjuster (B) slides over the horizontal support member (A3) of the bracket (A), and is between the mounting portion (A1) of the slide type bracket (A) and the mounting portion of the adjuster (B) body edge fixing. Adjust the length and secure with bolts in place. In the present invention, the horizontal support (A3) of the bracket (A) is provided with a loose hole (A4) and the adjuster (B) is provided with a bolt hole (B1) for fixing the length. It is possible to adjust the position of the adjuster (B) by providing a loose hole in one or both of the bracket and the adjuster. The length of the adjuster plane portion (B3) is an appropriate length depending on the length between the attachment portion (A1) of the slide bracket (A) and the attachment portion (B2) of the adjuster (B). In order to increase the strength of the adjuster (B), it is preferable to provide reinforcing bent portions (B4) in which both end portions are folded.

  The other end of the adjuster (B) can be securely fixed to the horizontal trunk edge (61) or the vertical trunk edge (62) by an appropriate method such as welding, trunk edge fitting (L-shaped fitting), bolt nut and tapping screw. Any method is acceptable. Further, the horizontal trunk edge (61) and the vertical trunk edge (62) are firmly fixed to each other by a trunk edge fitting (7) or the like. The body edge joint metal 7 is preferably one in which one end edge of a plate-like body bent into an L shape is bent at a right angle like a reinforcing bent portion (B4) of an adjuster (B) in order to increase strength.

  In the present invention, the slide-type bracket (A) and the adjuster (B) are simple in shape and extremely easy to manufacture, and the material can be made of iron-based materials such as various steel materials, so the cost is extremely low. Can be manufactured. The length of the slide bracket (A) and adjuster (B) can be adjusted by inserting a bolt and a nut into the loose hole between the loose hole provided on one side and the bolt hole provided on the other side at an appropriate position. By tightening and fixing, it is only necessary to adjust the length of the bracket mounting part of the bracket mounting part (A1) and adjuster (B), and the operation is also performed after fixing to the trunk edge (6). , There is an advantage that can be done without the need of skilled technicians at all. In this case, the reinforcing bent portion (B5) of the bracket and the reinforcing bent portion (B4) of the adjuster (B) are not only improved in the strength of the bracket, but also the horizontal support material (A3) of the bracket and the flat portion (B3) of the adjuster. It works effectively to keep the bonding direction accurate.

  Moreover, as shown in FIG. 2, the housing | casing (1) may be provided with the exterior material fixing attachment part (5). The outer wall of the building is vertical (planar) in most cases, and the thickness of the exterior material is constant from the upper floor to the lower floor, so the exterior material fixing mounting portion (in the building housing that fixes the exterior material ( Depending on the location of use, equilateral angle steel or unequal angle steel is used and fixed to the H-shaped steel of the building frame with bolts, welds, etc.) The exterior material mounting part surface is independent of the size of the frame (1) Usually, it is usually the same distance from the outer wall surface. For this reason, the distance from the exterior material fixing surface of the exterior material fixing mounting portion (5) to the body edge is constant, and in this case, a fixed length that does not have a length adjusting mechanism is used. Therefore, an integrated bracket (which may be the same as the fixed bracket in shape) that is simple in structure and low in cost is sufficient.

  The integrated bracket fixes one end to the exterior material fixing surface of the exterior material fixing attachment portion (5) attached to the building housing (1). As for the fixing method, there is no particular limitation as long as it can be securely fixed as in the case of the solid bracket. When the exterior material fixing surface of the exterior material fixing mounting portion of the housing is upward, the integrated bracket for fixing the trunk edge Or fix the upside down angle steel exterior material fixing surface with a sandwich plate, and when the angle steel exterior material fixation surface is facing down, screw it so that the sandwich plate does not come off the angle steel exterior material fixation surface. What is necessary is just to fix by the method of making it stop.

  The screw type mounting portion (41) of the integrated bracket (4) is fixed to the vertical outer material fixing surface (51) of the outer material fixing mounting portion (5) with the screw (42). Although not shown in FIG. 2, the barrel edge mounting portion on the opposite side of the bracket mounting portion is welded to the horizontal trunk edge (61) or the vertical trunk edge (62), or for the trunk edge joining as shown in FIG. Fix using hardware (7). Note that FIG. 2 shows the attachment of the outer wall 8 for horizontal installation. There are various other ways of attaching the dry wall material, and the present invention is not limited to this.

  The horizontal trunk edge (61) fixed to the exterior material fixing surface (51) with the integrated bracket (4) is formed using the vertical trunk edge (62) and the trunk edge joint metal fitting (7). Assemble. In this case as well, in order to reduce the distance between the new dry wall material (8) and the outer wall material (2) of the existing building, the vertical body edge (62) is cut to the distance between the horizontal body edges (61) to obtain the body edge joint hardware. It is preferable to prevent the thickness from increasing using (7).

  When the angle steel for fixing the exterior material is upward, as shown in FIG. 3, the exterior material fixing surface (51) of the angle steel for fixing the exterior material (5) is upward, and a sandwich plate can be inserted in the back. It is preferable to use the sandwiching plate type integrated bracket (43) because it is easy to operate. Although there is almost no risk that the mounting portion will come off, it is preferable to secure the scissors by providing a tapped hole (44) for safety. When the external material fixing surface (51) of the external steel material fixing angle iron (5) is facing downward, there are some cases where it is difficult to assemble because of a problem in place. In this case, a screw type integrated bracket is used. It is advantageous.

After attaching the body rim (6) to the adjuster (B) of the fixed bracket, integral bracket or slide bracket, the non-flammable filler such as rock wool is filled in the space of the core hole (3). It is preferable to seal the gaps by covering them. Although it may be stuffed with mortar or the like, since it is strongly bonded to the existing wall material 2, it may affect the wall material.
The body edge is fixed to the joint of the fixed bracket (40), the integrated bracket (4) or the adjuster (B) that has been extended to the outside of the outer wall (2) of the existing building, such as welding, joint hardware, screw fixing, etc. It is attached by means and functions as an attachment base for the dry wall material (8).

  Further, the trunk edge (6) is made of a square steel pipe or a lip groove steel or the like, and is formed of a rectangular steel pipe or a lip groove steel extending in the vertical direction with a horizontal trunk edge (61) mainly using a square steel pipe extending in the horizontal direction. There is a trunk edge (62). These are arbitrarily arranged on the surface of the outer wall (2) depending on the type of dry wall material (8), which will be described later, (vertically stretched type, laterally stretched type), and the necessary pitch of the trunk edge (6). Steel pipes or lip groove steels are commercially available at a low cost, and have a higher rigidity than conventional trunk edges (see FIG. 8). In this case, the trunk edge provides a space between the outer wall (2) and the dry wall material (8), but this space is preferably as small as possible. Therefore, it is preferable that the horizontal trunk edge (61) and the vertical trunk edge (62) are connected in the same plane by using, for example, a trunk edge joint metal (7) as shown in FIG. For this reason, the thickness of the trunk edge can be reduced (the same thickness as that of the square steel pipe) by providing a horizontal trunk edge for each floor and cutting the vertical trunk edge at an interval between them and joining them using a connecting metal fitting. Since square steel pipes or lip groove steels have high strength, there is no need for reinforcing metal fittings in the middle of each floor.

  Although this metal joint (7) is one in which the horizontal trunk edge (61) and the vertical trunk edge (62) are joined in the same plane (it can also be used for joining the bracket or adjuster to the trunk edge, etc.). In this case, an L-shaped joint hardware not provided with a reinforcing bent portion is fixed only on the surface, and a reinforcing bent portion is provided to reinforce and fix the joint from the side surface portion. Since the bonding strength is reinforced in the perpendicular direction, it is easy to obtain at least the same bonding strength as the number of metal fittings. It is possible to form an edge.

  The new dry wall material (8) covers the surface of the outer wall (2) of the existing building to form a new wall surface, and functions as a decorative material, waterproofing material, heat insulating material, fireproofing material, and fireproofing material for the building. Any outer wall material that does not impose a burden on the trunk edge (6) or the existing outer wall (2), preferably various lightweight ceramic siding materials having a cross section as shown in FIG. it can.

When such a ceramic siding is used, this is a general horizontal type ceramic industry in which a male connecting part is formed at one end of the dry wall material (8) and a female connecting part is formed at the other end. It is an example which shows a system siding material. In FIG. 7, a soft seal material S is interposed in the female connecting portion, and the waterproofness of the joint portion is improved.
Further, the attachment of the dry wall material to the body edge is performed by fixing the body edge attachment metal to the connecting portion of the dry wall material using a fixing tool such as a screw.

Here, the construction method of the repair structure of the outer wall according to the present invention will be briefly described with reference to an example.
First, as shown in FIG. 1, cored holes 3 are formed on the outer wall 2 from the surface side of the outer wall 2 using an equipment such as a hole saw at an arbitrary pitch along the arrangement position of the building housing 1. At this time, the pitch of the core hole 3 is about 600, 900, 1200, 1500 mm in the horizontal direction, and the pitch L in the vertical direction is different depending on the type of the building. It is about 3500 mm.
Next, a fixed bracket 40 whose length of the trunk edge support member 45 is prepared in advance as a trunk edge support member is inserted into the core punching hole 3, and the mounting portion 41 is connected to the housing 1, for example, the web 11 of H-type steel material. Attach it with screws. At this time, care should be taken so that the outer periphery of the bracket 4 does not touch the core hole 3 so as not to apply a load to the outer wall 2.

Next, a long horizontal barrel edge 61 is placed on the opposite side of the mounting portion 41 of the barrel edge support member 45 of the fixed bracket 40 and fixed by welding, screwing, or the barrel edge fitting 7 or the like.
The pitch at this time is determined by the required pitch of the trunk edge 6 of the dry wall material 8 to be attached, the wind pressure strength due to the ground height, and the like, for example, 600, 1200, 1800, 2000 mm, and the like.
Finally, the dry wall material 8 is attached to the trunk edge 6 with a fixing tool or the like, and the repair is completed. Of course, although not shown, a new outer wall surface is formed by constructing various drainage materials, starting materials, stiffener materials, cornering materials, cornering materials, opening members, and other various objects and sealing materials as necessary. It is.

  When the slide type bracket A is used as the trunk support member, the bracket 4 is inserted into the core hole 3, and the mounting portion 41 is fixed to the housing 1, for example, the H-type steel material web 11 with screws or the like. Install. At this time, care should be taken so that the outer periphery of the bracket 4 does not touch the core hole 3 so as not to apply a load to the outer wall 2. Next, the adjuster 5 is straddled on the horizontal support member 43 extending horizontally of the bracket 4 while adjusting the unevenness, and the bolts and nuts are loosely tightened and slid between the loose hole 44 of the bracket and the bolt hole 51 of the adjuster. The position of the adjuster 5 is adjusted while adjusting the distance between the bracket mounting portion 41 and the barrel edge mounting portion of the adjuster 5 and tightening the bolts and nuts to fix them.

  Next, the attachment part of the adjuster 5 is welded to the long horizontal trunk edge 61 or the vertical trunk edge 62, and is fixed to the trunk edge using a bolt or a joint metal.
