Description

  The present invention relates to a method for externally constructing a dry adhesion layer type heat insulating composite panel on the concrete outer wall of a reinforced concrete building, and more specifically, without using an adhesive on the concrete outer wall. In addition, regardless of whether the concrete outer wall is uneven or not, it is installed on the same surface and belongs to the technical field of architecture.

  Reinforced concrete exterior thermal insulation buildings are coated with a thermal insulation layer on the outside of the concrete frame, so that cracking of the concrete due to thermal stress due to solar radiation can be suppressed, and the concrete frame is not exposed to the outside air. Can be suppressed, corrosion of the steel bars can be suppressed, the durability of the building is improved, and the outer surface of the entire building is covered with a heat insulating layer. It is superior in heat insulation construction and heat insulation efficiency than thermal insulation coating, and is evaluated as an energy-saving building.

FIG. 7 shows a method for laying a composite panel as a conventional example 1 and is shown in Non-Patent Document 1.
That is, as shown in FIG. 7 (A), the conventional outside construction method is a magnesium cement board having magnesium oxide and cinnabar as the main components, embedded with glass fiber nonwoven fabric on both sides, and molded to a thickness of 12 mm. Adhesive-type composite panel (EB Co., Ltd., EB Thin Panel (trade name)) in which the exterior base material and the heat insulating material are integrated in layers, and the heat insulating composite panel is put into concrete through a dumpling adhesive. It is bonded to the outer wall surface, and a dry anchor is driven into the concrete outer wall from the surface of the heat insulating composite panel, and the composite panel is externally attached to the concrete outer wall.

That is, the composite panel is stretched to clean the surface of the concrete body and improve the adhesiveness of the adhesive. As shown in FIGS. 7C and 7D, the horizontal direction of the panel and the vertical direction are both ends, And from the upper and lower ends, the adhesive is 5 to 10 mm thick and the length is 80 to 100 mm on the side so that the interval is 200 to 250 mm, and is attached to the surface of the concrete frame. The heat insulating layer is bonded to the concrete frame via an adhesive.
As shown in FIG. 7 (B), the dry anchor is attached to the left and right sides of the panel at 100 mm from both sides, with a distance of 700 mm or less. It is arranged so that the interval is within 920 mm, and a dry anchor having a nylon plug attached to the tip is driven into the concrete frame through an anchor insertion hole previously drilled in the exterior base material of the composite panel. .

FIG. 8 shows a conventional example 2, which is also cited as a conventional example in Japanese Patent No. 3753719 (Japanese Patent Laid-Open No. 2005-68791) owned by the present applicant. This is panel panel construction technology.
That is, in Conventional Example 2, as shown in FIG. 8, a GFPC-based exterior material (volcanic gravel sand ash phenol resin plate mixed with double-sided glass fibers having a thickness of 13 mm) and a heat insulating material are bonded and integrated to form an adhesion layer type. A composite panel (Okuma YB-R (trade name) manufactured by Iwakura Chemical Industry Co., Ltd.) is used.

The exterior material is provided with holes for post-construction anchors at appropriate locations, and on the surface of the heat insulation layer, dumpling adhesive is arranged at appropriate intervals, and the insulation layer of the panel is made of concrete with the dumpling adhesive. Adhering to the surface of the frame, and then driving the construction anchor from the exterior material surface to the concrete frame, the composite panel is stretched on the surface of the concrete frame.
The gap between the lower end of the lowermost panel and the drainage is sealed with sealing, and the upper end of the uppermost panel is covered with a waterproof layer together with the upper end of the parapet, and the angle headboard is attached.

In the external construction method of Conventional Example 1 (FIG. 7), the heat insulating layer of the composite panel and the surface of the concrete frame are fixed with an adhesive, so that the adhesion of the surface of the concrete frame is enhanced when the panels are attached. In addition, it is essential to clean the surface of the concrete body, and the cleaning operation is a complicated operation requiring attention.
Moreover, the adhesive performance changes depending on the weather at the time of construction because the adhesive performance changes in rainy weather, extreme heat and severe winter.

  In addition, in order to stick the panel surface flush regardless of the unevenness of the surface of the concrete body, it is necessary to cope with the degree of pressing flattening of the dumpling adhesive, and the dumpling adhesive having a thickness of 5 to 10 mm There is a limit to the absorption of unevenness on the surface of the concrete frame due to pressing deformation at the center, and the work of unifying the pressing surface to the surface of the concrete frame from the surface side to the composite panel requires labor and manpower. In addition, it is difficult to make the composite panel flush with each other because the operation involves variation.

In addition, the arrangement of a predetermined amount at predetermined intervals on the surface of the concrete frame is also a complicated operation so that the dumpling adhesive is at a predetermined position of the panel.
When the composite panel is externally constructed on the existing concrete frame by the method of the conventional example 1, the surface of the concrete outer wall is usually uneven, so the surface of the concrete outer wall is leveled by the rolling operation. Work is also required, and the preparation work for flushing the composite panel is a complicated and difficult work.

In addition, even in the case of the prior art 2 (FIG. 7), the composite panel is adhered to the surface of the concrete frame by aligning the adhesive dumper with the required position of the composite panel. Because the thermal insulation layer of the composite panel is bonded to the concrete frame surface, it will respond to the unevenness of the concrete frame surface due to the pressure deformation of the dumpling adhesive, and the concrete frame surface can be turned as necessary. In addition, the cleaning operation of the surface of the concrete body, the arrangement operation of the dumpling adhesive, and the like are complicated and troublesome operations, and it is difficult to externally lay the composite panel.
The present invention solves the problems of the conventional examples 1 and 2, and without using a dumpling adhesive, the composite panel can be externally flushed regardless of the unevenness of the concrete frame surface. It provides an innovative method.

  As shown in FIG. 1, the present invention is a method of laying a dry adhesion layer type heat insulating composite panel on the concrete outer wall of a reinforced concrete building, and at the lower end position of the lowermost composite panel 1, Then, the angle-shaped panel bracket 7A is fixed with the post-casting bolt anchor 7B, and the post-casting anchors 4C and 4C ′ whose outer periphery of the rear end is a threaded surface 4S as shown in FIG. Then, the rear end screw surface 4S is driven and fixed in a projecting form, and then the flat pad 4B, 4B 'is screwed onto the rear end screw surface 4S of each rear anchor 4C, 4C'. Then, the rear end surface of each flat pad 4B, 4B 'is measured and each pad 4B, 4B' is arranged flush, and then the lower end of the lowest composite panel 1 is supported by the panel bracket 7A, Each composite panel 1 The heat insulation layer 1B surface is brought into contact with each flat pad 4B, 4B ', and is fixed to the concrete outer wall W in a uniform manner by the fixing brackets 4A, 13A, 14A.

  In this case, the heat insulating composite panel 1 may be a dry adhesion layer type panel that can cover the concrete outer wall W with heat insulation, and the exterior material (exterior base material) and the heat insulation layer used in the conventional examples 1 and 2 are integrated. Even if it is a layered panel, the ventilation of the utility model registration No. 3084180 owned by the applicant of the present application, in which the extruded cement board and the heat insulating layer are vertically formed with a group of grooves for ventilation on the inner surface. Typically, a heat insulating composite panel may be used, but typically, as shown in FIG. 4, a groove group for ventilation is provided vertically on the surface of the heat insulating layer 1B to form an EB thin panel (trade name) or the like. It is a breathable heat insulating composite panel in which thin rigid plates are layered and integrated.

The flat pads 4B and 4B 'are only required to provide a vertical surface whose rear end surface can resist the pressing force of the composite panel 1 and can be measured in a state where the flat pad 4B, 4B' is screwed onto the rear anchor 4C. A plastic disk or a steel plate disk may be used.
The panel bracket 7A serves as a starter at the lowermost end of the composite panel 1 that is connected to the upper and lower sides, firmly supports the lowermost panel, and is a long object. Is JIS G 3192 4 mm thick equilateral angle steel.

  Further, the fixing brackets 4A, 13A, and 14A only need to be able to integrally fix the composite panel 1 to the concrete outer wall W. As shown in FIG. As shown in FIG. 5, a long screw 13A is used as the fixing bracket, a steel plate pad is used as the flat pad 4B, and the long screw 13A is attached to the panel. Perforation screwing may be fixed to the pad 4B from the outer surface, or the fixing anchor 14A may be employed as a fixing bracket as shown in FIG. 6, and the fixing anchor 14A may be driven directly into the concrete outer wall W from the outer surface of the panel 1. .

Accordingly, the present invention adjusts the front and rear positions of the flat pad 4B group on the rear strike anchor 4C while measuring the flat plate pad 4B group that is screwed onto the rear strike anchor 4C. By arranging the contact surface) flush, each composite panel 1 group can be positioned by the flat pad 4B group and can be placed flush as measured, regardless of the unevenness of the surface Wf of the concrete outer wall W. .
Then, by arranging the flat plate pad 4B as a measurement standard in contact with the maximum uneven portion of the concrete outer wall surface Wf, each composite panel 1 group is flush with the concrete outer wall W. It can be stuck with the interface gap ad minimized.
The composite panel 1 is fixed to the concrete outer wall W with the fixing bolt 4A, the long screw 13A, or the fixing anchor 14A. Therefore, it can be easily fixed integrally to the concrete outer wall W in the same form.

The lowermost composite panel 1 is firmly supported and held also by the panel bracket 7A, and depending on the weight of the panel 1 to be employed, for example, the fixed anchor 14A is driven into the required position, etc. By appropriately implementing the number and arrangement of the fixtures 4A, 13A, and 14A, it is possible to firmly and integrally fix to the concrete outer wall W.
Moreover, since it is not necessary to attach an adhesive to the concrete outer wall W, the panel can be installed without being influenced by the weather.
Therefore, the construction method for the composite panel group according to the present invention, which is externally attached to the concrete outer wall without using an adhesive, is advantageously employed not only for the external construction at the time of new construction, but also for the dry coating repair method for existing reinforced concrete buildings. I can do it.

Further, in the present invention, as shown in FIG. 3, the composite panel 1 is integrally fixed to the concrete outer wall W, and the fixing bolt 4A inserted from the outside of the composite panel 1 is screwed and fixed to the post-fixed anchor 4C. It is preferable to carry out.
In this case, the rear anchor 4C is designed by changing the design of a strong anchor (Sanko Techno Co., Ltd., trade name) having a conventional outer diameter of 12 mm and a length of 35 mm, and extending the rear part (15 mm). It is only necessary to prepare a thread surface 4S and the inside of the extension as a 15 mm long screw hole hi, and the post-casting anchor 4C exhibits a strength of 1300 kgf / cm ² per one tensile load.
The fixing bolt 4A may be a stainless steel screw bolt having a diameter of 8 mm and a length of 85 mm with a flat head having a diameter of 14 mm.

  Therefore, a position corresponding to the bolt insertion hole hb drilled in the composite panel 1 is marked on the concrete outer wall W. Based on the mark, the concrete outer wall W is drilled, and the post-placed anchor 4C is placed in the drill hole. After fixing, if the fixing bolt 4A is inserted into the bolt insertion hole hb from the surface of the exterior base material 1A of the composite panel 1 and screwed and fastened with the screw hole hi at the rear part of the post anchor 4C, the composite panel 1 The composite panels 1 are in contact with the flat plate pad 4B which is set to be measured, and can be firmly integrated and fixed to the concrete outer wall W.

Further, in the present invention, as shown in FIG. 5, when the composite panel 1 is integrally fixed to the concrete outer wall W, the long screw 13A inserted from the outside of the composite panel 1 is attached to the metal flat pad 4B ′. It is preferable to carry out by inserting and fixing.
In this case, a conventional all-anchor (trade name, manufactured by Sanko Techno Co., Ltd.), which is a stainless steel pipe product having an outer diameter of 8 mm and a length of 24 mm, can be adopted as the post-cast anchor 4C ′. 'it is 1 Hontori, tensile load 500 kgf / cm ^2, exhibits the strength of the shear load 684kgf / cm ^2.
Further, as the flat plate pad 4B ′ made of metal, a steel plate disk having a diameter of 80 mm and a thickness of 3.2 mm and having a screw hole hp having a diameter of 8 mm at the center may be used.
Further, the long screw 13A may be a steel screw having a diameter of 5 mm and a flat head having a diameter of 12 mm and a length of 95 mm.

  Accordingly, the metal flat plate pad 4B ′ has sufficient resistance against the pressing force from the composite panel 1 in a state where the metal flat plate pad 4B ′ is screwed onto the post-casting anchor 4C ′. It is possible to fix the long screw 13A from the surface of the composite panel by screwing through the panel 1 and the pad 4B ', and it is also necessary to make an insertion hole in the exterior base material (cement board) on the surface of the composite panel in advance. In addition, since the long screw 13A is freely screwed and fixed to the surface of the wide pad 4B 'having a diameter of 80 mm, the long screw 13A is screwed and driven without the need for strict alignment between the long screw 13A and the pad 4B'. The composite panel 1 can be stretched on the concrete outer wall W with good workability.

In the present invention, the composite panel 1 is integrally fixed to the concrete outer wall W by driving the fixed anchor 14A inserted from the outside of the composite panel 1 into the concrete outer wall W as shown in FIG. Is preferred.
In this case, the trailing anchor 4C ′ simply holds the flat plate pad 4B, so that a conventional all-anchor (manufactured by Sanko Techno Co., Ltd., trade name) can be adopted, and the fixed anchor 14A has a diameter of A stainless steel long screw with a diameter of 6 mm and a length of 130 mm with a flat head of 10 mm and a P-less anchor (trade name) manufactured by Sanko Techno Co., Ltd. may be used.
Accordingly, the fixed anchor 14A simply passes through the panel 1 from the free position on the surface of the composite panel 1 and drives the concrete outer wall W to fix the composite panel 1, and the fixed anchor 14C ′ and the pad 4B. However, since it is in charge of adjustment and confirmation of the position of the composite panel 1 in the front-rear direction, the workability of the composite panel 1 on the surface is good.

The composite panel 1 is a heat insulating composite panel in which a plate-like heat insulating layer 1B made of foamed plastic heat insulating material and an exterior base material 1A made of a molded thin rigid plate having a smaller moisture resistance than the heat insulating layer 1B are layered. preferable.
In this case, the foamed plastic-based heat insulating material may be a JISA9511 foamed plastic-based heat insulating material such as an extruded polystyrene foam or a rigid urethane foam, and is typically a 75 mm-thick JISA9511 extruded polystyrene foam plate.
In addition, the exterior base material 1A of the molded thin rigid plate has a lower moisture permeability resistance than the heat insulating layer 1B, and is a thin rigid plate (cement plate) having strength, impact resistance, and dimensional stability as the exterior base material of the outer wall. If the specific gravity is small, it is particularly preferable. Typically, light weight (10 kg / m ² ), high strength (100 kgf / cm ² ), moisture permeability resistance (14 m ² hmmHg / g), thickness 12 mm This is a magnesium cement board.

Therefore, the composite panel 1 can be stretched flush with the concrete outer wall W through the flat pads 4B and 4B 'that are measured and arranged in a plane, and is flat regardless of whether the concrete outer wall W is uneven. While constructing a flush outer wall, the moisture permeability resistance (14 m ² hmmHg / g) of the exterior base material outside the heat insulation layer 1B is the moisture permeability resistance (52.5 m ² ) of the heat insulation layer 1B (extruded polystyrene foam 75 mm thickness). hmmHg / g), the composite panel 1 becomes a moisture permeable outer wall, and the moisture of the heat insulating layer 1B is moisture permeable and released from the cement board (exterior base material) 1A to the outside to suppress internal condensation. Provide an insulated outer wall structure.
In addition, if the specific gravity of the exterior base material 1A is small, the weight of the composite panel 1 can be reduced, the composite panel 1 can be easily handled, and the tensioning operation can be facilitated. Fixing support becomes easy, and the metal fitting can be reduced in weight, which is advantageous.

Further, the composite panel 1 is a breathable heat insulating composite panel in which a plate-like heat insulating layer 1B of a foamed plastic heat insulating material and an exterior base material 1A in which ventilation grooves G are vertically arranged on the inner surface are layered. Is preferred.
In this case, the breathable heat insulating composite panel 1 is typically a breathable heat insulating composite panel of Utility Model Registration No. 3084180 owned by the present applicant.
Therefore, when the breathable heat insulating composite panel is applied to the present invention, the flattening of the composite panels 1 in the construction of the outer surface of the concrete outer wall W can cause the surface Wf of the concrete outer wall W to be uneven. It can be easily constructed regardless of the extent, and the extrusion-molded cement board as the exterior base material 1A has a high strength, so it is possible to apply heavy exterior materials such as tiles, and the groove G is a ventilation layer. Construction of a breathable outer heat insulating outer wall can be carried out with good workability.

In the present invention, as shown in FIG. 4, the composite panel 1 includes a heat insulating layer 1B in which a ventilation groove G group is vertically arranged in parallel on the layering surface 1S of the foamed plastic heat insulating material, and the thickness is A breathable heat insulating composite panel in which a molded thin rigid plate exterior base material 1A having a specific gravity of 0.8 to 1.0 is 12 to 15 mm is particularly preferable.
In this case, the heat insulating layer 1B of the foamed plastic-based heat insulating material is a shape-retaining shape that can be attached in an integrated layer without crushing the groove G with the outer base material 1A of the molded thin rigid plate and the protruding thick part 1C between the grooves G. Any suitable plate-like material may be used, such as an extruded polystyrene foam, a beaded polystyrene foam, a rigid urethane foam, and the like. It is an extruded polystyrene foam of JISA9511.

Further, the ventilation groove G group is notched with a cutter to a depth that guarantees a minimum ascending flow of the draft air flow a and keeps the insulation defect due to the notch of the groove G group of the heat insulating layer 1B to a minimum. Typically, each groove G has a depth Gd of 15 mm and a width a1 of 45 mm, and the width a1 of the groove G and the width a2 of the thick portion 1C are equal.
Moreover, the exterior base material 1A of the molded thin rigid plate may be a thin rigid plate (cement plate) having the minimum strength, impact resistance, and dimensional stability as the exterior base material of the outer wall, and the plate thickness is If it is 15 mm or less and the specific gravity is 1.0 or less, the composite panel 1 as a whole can be reduced in weight and can be handled easily.

That is, as the exterior base material 1A, as shown in FIG. 4C, magnesium oxide and cinnabar sand are the main components, and a glass fiber nonwoven fabric Gc is embedded on both sides. A 12 mm magnesium cement plate 1A-1 is suitable for light weight (10 kg / m ² ) and high strength (100 kgf / cm ² ), and the dredged sand, slaked lime, and pulp shown in FIG. 4 (D) are dispersed in water. Formed into layers and combined with calcium oxalate Ca generated by autoclave curing, vermiculite Va is added to the base material, light weight (13.2 kg / m ² ), high strength (100 kgf / cm ² ) 12 mm As shown in FIG. 4 (E), a thick calcium silicate plate 1A-2, and light weight (12.12) made of volcanic gravel Ka and fly ash as main raw materials and glass fiber used as a reinforcing material. 4kg / ^2), a high strength (100 kgf / cm ^2), the 13mm thick phenolic resin plate 1A-3 is preferably be employed.

Therefore, since the composite panel 1 arranges the groove G group on the heat insulation layer 1B side, the size and shape of the groove G are under the condition that the heat insulation defect is suppressed within the allowable limit and the ventilation function is exhibited. In addition, the size and shape can be freely arranged with a cutter, and the cement plate 1A can be a flat plate because it can be a flat plate, and the unit area is a lightweight panel. The panel 1 can be attached to the concrete outer wall W by using an adhesive without using an adhesive, and it is easy to arrange the surface flush with the flat pad 4B. It can be implemented with good workability.
Moreover, since the outer wall to be obtained is a breathable outer heat insulating wall, it is possible to suppress the occurrence of internal condensation, to suppress moisture absorption that causes a decrease in the heat insulating function of the heat insulating layer 1B, and to suppress the heat stress of the exterior base material (cement board). It becomes a high quality outer heat insulating outer wall.

Further, in the present invention, the upper and lower and left and right connections between the composite panels 1 are constructed by phase-separated connection by the abutting contact of the heat insulating layer 1B of each composite panel 1, and the lower end of the lowermost composite panel 1 and The interface gap ad with the surface Wf of the concrete outer wall W is preferably airtightly sealed.
In this case, in the composite panel 1, for example, as shown in FIGS. 4A and 4B, the heat insulating layer 1B protrudes from the cement board (exterior base material) 1A so that the step d3 protrudes on the upper side and the step d2 on the lower side. It suffices to project the step d1 on the left side 1L and to enter the layer by entering the step d1 on the right side 1R.

  Therefore, the upper and lower and left and right connections of each composite panel 1 are in contact with each other by the abutting contact between the heat insulating layers 1B, so that the heat insulating layer 1B covering the concrete outer wall W becomes a form having no gap and has a heat insulating function as designed. Even if a slight gap occurs at the abutting contact interface of the heat insulating layer 1B, the contact interface between the heat insulating layers 1B is closed and protected on the surface of the cement board 1A due to the interphase connection between the panels. Intrusion of outside air into the contact interface of the layer 1B can be suppressed, and a decrease in heat insulation function due to air intrusion from the contact interface of the heat insulation layer 1B can be suppressed.

Moreover, since the composite panels 1 are arranged in contact with each other at the top and bottom and the left and right edges with a phase defect connection, the contact arrangement of the panels 1 by hand can be performed with good workability.
Further, at the lower end of the composite panel 1 at the lowermost end, in order to prevent air from flowing into the interfacial gap ad between the inner surface of the panel heat insulating layer 1B and the concrete outer wall surface Wf, it exists due to unevenness of the concrete outer wall surface Wf. The air in the interface gap ad becomes a sealed air layer and functions as an air heat insulating layer.

  In the present invention, as shown in FIG. 2, the lowermost composite panel 1 has a cross-sectional shape of a horizontal upper plate 8U, a falling plate 8B from the tip of the horizontal upper plate, and a falling plate 8B. A waist plate having an inclined plate 8S and a falling piece 8F from the tip of the inclined plate 8S, an air hole H8 at the front end of the horizontal upper plate 8U, and a protruding piece 8A at the lower surface of the rear end of the air hole H8. The drainage 8 is placed on the horizontal piece 7F of the panel bracket 7A, and the composite outer wall W is placed on the waist drainer 8 with the composite panel 1 in which the lower end of the exterior base material 1A projects a small step d2 from the lower end of the heat insulating layer 1B. Then, it is preferable to knock out the waist drainer 8 until the falling plate 8B contacts the inner surface of the exterior base material 1A.

In the present invention, the lowermost composite panel 1 is a panel located on a long drainage panel disposed at the lower end of the outer wall.
As shown in FIG. 2A, the dimensional relationship between the waist drainer 8 and the panel bracket 7A is such that the width Wu (standard: 53 mm) of the horizontal drainage horizontal upper plate 8U is the thickness T3 of the heat insulating layer 1B (standard: 75mm), with the protruding piece 8A on the lower surface of the horizontal draining horizontal upper plate 8U in contact with the tip of the horizontal piece 7F of the panel bracket 7A, the falling plate 8B and the cement plate at the lower end of the composite panel In the relationship where there is a gap between the inner surface of 1A, that is, in the state where the protruding piece 8A is in contact with the tip of the horizontal piece 7F, for example, the composite panel 1 is lowered onto the horizontal upper plate 8U without the interface gap ad. Even if the panel is placed below, the inner surface of the lower end of the panel cement plate 1A may be set so that it does not collide with the lowering water falling plate 8B.
The dimensional relationship between the waist drainer 8 and the lower end of the composite panel 1 is such that the inclined plate 8S is sealed between the lower end of the exterior base material 1A with the lower end surface of the heat insulating layer 1B placed on the horizontal upper plate 8U. It is only necessary to set the relationship to form a gap for use.
Further, the air holes H8 of the waist drainer 8 may be formed so as to correspond to the lower ends of the respective grooves G of the composite panel 1.

  The lowermost composite panel 1 group also has a lower back, that is, the inner surface of the heat insulating layer 1B is placed in contact with the flat pads 4B and 4B 'on the post-cast anchors 4C and 4C' driven into the concrete outer wall W. On the drained horizontal upper plate 8U, even if there is a difference in degree between the composite panels 1, there is at least a flat plate between the inner surface of the lower end projecting portion of the exterior base material 1A and the outer surface of the lower water draining falling plate 8B. A gap having a thickness (standard: 3 mm) of the pads 4B and 4B 'is generated, but the waist drainer 8 is sandwiched between the upper surface of the horizontal upper plate 8U of the panel bracket 7A and the lower end surface of the panel heat insulating layer 1B. Therefore, if the inner surface of the falling plate 8B is hit with a mallet and the waist drainer 8 is knocked outward, the falling plate 8B can be brought into contact with the inner surface of the protruding portion of the exterior base material 1A. The descending piece 8F has a uniform protruding form.

Therefore, the waist drainer 8 has the protruding piece 8A for position regulation placed in contact with the tip of the horizontal piece 7F of the panel bracket 7A, and the composite panel 1 is simply placed on the waist drainer 8 and is placed on the concrete outer wall W. After fixing with the fixing bolt 4A, the fixing long screw 13A, the fixing anchor 14A, etc., the construction of the lowermost end panel and the waist drainage can be performed simply by knocking out the waist drainer 8 with a mallet.
When the panel 1 is placed on the lower drainage 8, the falling plate 8B of the lower drainage 8 is in the retracted position, so that the protrusion d2 of the exterior base material 1A of the panel 1 collides with the lower drainage 8. Damage can also be prevented.

  Then, as shown in FIG. 2 (A), the lower ends of the exterior base material 1A and the exterior finish material 2 are finished with a conventional backup material 12B and a sealing 12, and a protruding piece 8A and a horizontal piece 7F on the lower surface of the waist drainer 8 are finished. If the space between the front end is filled with the sealing 12 and the sealing 12 is also filled in the gap between the lower end of the vertical piece 7W of the panel bracket 7A and the concrete rising portion 5, the surface Wf of the concrete outer wall W and the inner surface of each composite panel 1 The interfacial gap ad can prevent inflow of air from below, and the air in the interfacial gap ad up to the uppermost end of the outer wall becomes a heat insulating air layer with respect to the concrete outer wall W. The inflow of the draft rising air flow a from the air hole H8 is ensured, and the breathable heat insulating composite panel 1 is applied to the breathable heat insulating outer wall for the concrete outer wall W where there is unevenness, and waist water Arrangement of 8 homogeneous, and, workability can be implemented.

In the present invention, the lowermost composite panel 1 is preferably such that the groove G group of the heat insulating layer 1B communicates with the lower transverse groove G ′ as shown in FIG. 2 (A). .
In this case, when the composite strip 1 is manufactured, the transverse groove G ′ is notched at the lower end of the heat insulating layer 1B at the same time as the notch is formed by the cutter of each vertical groove G group on the layering surface 1S of the heat insulating layer 1B. What is necessary is just to form, and the depth and width | variety of the transverse groove G 'should just be formed the same as the longitudinal groove G. FIG.

  In this case, since the transverse groove G ′ has a port function with respect to each groove G of the heat insulating layer 1B of the composite panel 1, the air hole H8 of the drainage drainage 8 has the transverse groove G ′. Therefore, the air hole H8 of the pelvic drainage is formed to communicate with the transverse groove G ′, and it is only necessary to drill round holes at an appropriate interval (standard: 150 mm), and the strength of the pelvic drainage 8 is reduced. In addition, since the arrangement of the air holes H8 may be small, the waist drainer 8 can be easily manufactured.

  According to the present invention, while measuring the flat board pads 4B and 4B 'screwed onto the post-cast anchors 4C and 4C' driven into the concrete outer wall W, the post-cast anchors 4C and 4C 'are measured. Since the front and rear positions are adjusted and installed in the same plane, each group of composite panels can be installed in a single plane regardless of the unevenness of the surface Wf of the concrete outer wall W.

  In addition, fixing the composite panel 1 to the concrete outer wall W requires a complicated and difficult spotting work of a dumpling adhesive and a panel pressing work that causes personal errors of workers as in the past. Instead, since it is carried out only with a fixing bracket such as the fixing bolt 4B and the panel receiving bracket 7A at the lowermost end, uniform panel stretching can be performed with good workability with a simple operation.

In addition, in conventional panel stretching with an adhesive and an anchor, the adhesive is affected by the weather because the adhesive performance is affected when the adhesive is cold or warm or rainy. However, in the present invention, the panel is stretched with adhesive. The panel can be installed efficiently without being influenced by the weather.
