Description

  The present invention relates to a mounting structure and a fixture for a concrete wall and a thermal insulation panel, and in particular, by transferring heat from the outer layer portion of the thermal insulation panel to the concrete wall via the fixture for attaching the thermal insulation panel to the concrete wall. The present invention relates to a mounting structure and a fixture for a concrete wall and a thermal insulation panel that can effectively prevent the resulting condensation and can firmly attach the thermal insulation panel to the concrete wall.

  As a heat insulating structure for a structure having a concrete wall, a structure in which a heat insulating panel is bonded to the outer wall surface of a concrete wall is well known. By the way, an outer heat insulation structure in which mortar is applied to the outside of the heat insulation panel to form an underlayer and tiles are attached to the outside to finish the outer layer is also common, but in this outer heat insulation structure, If the heat insulation panel is simply bonded to the concrete wall, there is a high risk that the heat insulation panel will be peeled off from the concrete wall due to the weight of the tiles. Therefore, in the case of such an external heat insulating structure, it is common to use a fixture such as an anchor bolt that penetrates the heat insulating panel and is partially embedded in the concrete wall.

  Conventionally, various techniques have been disclosed regarding a mounting structure for attaching a thermal insulation panel to the concrete wall or a fixture used for the mounting structure. For example, in the heat insulating panel mounting structure according to Patent Document 1 disclosed by the applicant, a counterbore portion is formed on one side of the heat insulating panel and a through hole is formed from the counterbore portion to the other surface of the panel. A mounting structure is disclosed in which a female screw having a flange portion is fitted into the through-hole and the counterbore portion, an anchor male screw is screwed into the female screw, and the anchor male screw is embedded in a concrete wall. According to this invention, since the concrete wall and the heat insulation panel can be firmly fixed only by the female screw and the anchor male screw attached to the heat insulation panel, it is possible to reduce the number of assembly parts and simplify the assembly work. it can.

  However, in the above mounting structure, since the female screw and the male screw are made of a steel material, a so-called heat bridge is formed in which heat from the outside of the heat insulation panel is transmitted to the concrete wall via the female screw and the male screw. However, this heat bridge may cause a problem that condensation occurs in the boundary region between the heat insulation panel centering on the screw member and the concrete wall. Condensation can cause mold walls to become soiled with concrete.

  The invention which prevents generation | occurrence | production of the dew condensation resulting from the above-mentioned heat bridge is disclosed by patent document 2,3. The invention disclosed in Patent Document 2 relates to a drop-off prevention tool used when a heat insulating composite plate is attached to a concrete wall. This drop-off prevention device is composed of a bolt that penetrates the heat insulating composite plate and an anchor that is screwed to the bolt and is embedded and fixed in the concrete. The feature is that the anchor is on the back surface of the heat insulating composite plate. It has a large flange part that comes into contact, and a convex part that is not sharp is provided on the collar part, and the convex part bites into the heat insulating composite board to fix the heat insulating composite board to the concrete wall, and a preferable anchor A synthetic resin having poor thermal conductivity is used as the material of the material (for example, paragraph 0006 of the specification). By using an anchor made of a material with poor thermal conductivity, even if heat from the outside of the heat insulating composite plate is transmitted to the bolt, it is not effectively transferred to the anchor, so near the boundary between the concrete wall and the heat insulating composite plate. The possibility of condensation is very low.

  On the other hand, also in the outer heat insulating structure disclosed in Patent Document 3, the anchor embedded in the concrete wall is described in Patent Document 2 when fixing the heat insulating composite plate obtained by integrating the heat insulating material and the outer layer material and the concrete wall. There is a description that it is preferable to mold with a synthetic resin (paragraph 0010 of the specification).

  According to the anchors disclosed in Patent Documents 2 and 3, since the steel bolt and the anchor do not form a heat bridge to the concrete wall, it is possible to effectively prevent the occurrence of condensation near the boundary between the heat insulating material and the concrete wall. Can do. However, since the anchor is molded from a resin material such as synthetic resin, the fixing strength of the heat insulating material (heat insulating panel) and the concrete wall is significantly lower than when both the bolt and anchor are made of steel. To do. The term “fixing strength” as used herein means a bending strength or a pulling strength that the anchor can exert against a bending moment or a pulling force acting on the anchor via a bolt. In order to increase the bending strength and pull-out strength, it is necessary to increase the number of fixtures made up of bolts and anchors, and it is undeniable that the construction cost will increase due to the increase in the number of parts and the labor will be increased.

  The concrete wall and heat insulating panel mounting structure and mounting tool of the present invention have been made in view of the above problems, and the mounting tool for mounting the heat insulating panel and the concrete wall forms a heat bridge that causes condensation. Furthermore, it is an object of the present invention to provide a concrete wall and heat insulation panel mounting structure and fixture capable of firmly fixing the heat insulation panel and the concrete wall with as few fixtures as possible.

  In order to achieve the above object, a concrete wall and heat insulating panel mounting structure according to the present invention is a heat insulating panel mounting structure formed on one side of the concrete wall, and is formed in the thickness direction of the heat insulating panel. A female screw member is fitted into the hole, and a male male screw member is screwed into the female screw member in a posture in which a part of the male screw member is embedded in the concrete wall, and at least a portion of the male screw member embedded in the concrete wall Is characterized in that a resin layer is formed on the surface thereof.

  Here, the heat insulating panel is a panel in which the outer layer base material and the heat insulating material constituting the indoor side or the outdoor side of the concrete wall of the structure are bonded together, and the mounting structure of the present invention is also applied to the outer heat insulating structure. It can also be applied to an inner heat insulating structure. As the outer layer base material, for example, ceramic, cement-based, or wood-based face materials can be used. Moreover, as a heat insulating material, in addition to synthetic resin foams such as polystyrene foam, polyethylene foam, polyurethane foam, and phenol foam, board-like inorganic heat insulating materials such as glass wool and rock wool can be used. Here, what is necessary is just to determine the foaming magnification in the case of using a resin foam suitably according to the heat insulation performance required.

  The concrete wall and the heat insulation panel are attached by placing concrete between the heat insulation panel and the formwork arranged at a predetermined interval, waiting for the concrete to harden, and then removing the formwork. Is installed. The heat insulating panel is provided with a predetermined number of through holes extending in the thickness direction, and a steel female screw member, for example, is fitted into the through holes when the concrete is placed. Here, the term “steel” means a metal made of iron or iron as a main component and any one or more of carbon, nickel, chromium and the like mixed at an appropriate ratio. The steel female screw member is preferably subjected to rust prevention treatment such as galvanization treatment or aluminum vapor deposition treatment on the surface thereof. The length of the female screw member is set to an appropriate length that is equal to or less than the thickness of the heat insulating panel.

  On the other hand, the male screw member that is screwed to the female screw member has a length that can obtain a desired anchor effect by forming a predetermined embedding length from the heat insulation panel to the concrete wall when screwed to the female screw member. ing. The anchor effect here refers to pull-out strength and bending strength. Moreover, as the raw material, it can shape | mold, for example with the above-mentioned steel material.

  A resin layer is formed on the surface of, for example, a steel core in at least a portion of the male screw member embedded in the concrete wall. This resin layer is provided to block heat from the outside of the heat insulation panel from passing through the female screw member and finally to the concrete wall even if it passes through the steel core of the male screw member. In addition, even if the female screw member and the male screw member form a heat bridge, the possibility of causing condensation can be extremely reduced. Here, examples of the resin used include polyvinyl chloride, polyethylene, polypropylene, polyurethane, and epoxy resin. Of these, polyethylene and polypropylene having low thermal conductivity and excellent chemical resistance are preferable. Concrete walls contain various additives (retarders, thickeners, etc.) depending on the application in addition to the main components of cement, coarse aggregate, fine aggregate, and sand. Chemical resistance is also required.

  Moreover, the formation method (coating method) of the resin layer in the male screw member is not particularly limited, and can be selected according to the resin used. For example, polyvinyl chloride and polyethylene can be coated by dip coating, fluid dip method and electrostatic coating method, polypropylene and epoxy resin can be coated by fluid dip method and electrostatic coating method, and polyurethane can be coated by spray coating. In addition, as another method, there is a method in which a core material is inserted into a resin layer previously formed into a cylindrical shape, and the resin layer is fused by heating the whole.

  In actual construction, as described above, the female screw member is fitted into the through hole provided in the heat insulating panel, the male screw member is screwed into the female screw member, and then concrete is driven between the molds facing the heat insulating panel. As a result of curing, the male screw member is embedded in the concrete wall, and the mounting structure of the concrete wall and the heat insulating panel is formed by the female screw member that is combined with the male screw member.

  According to the mounting structure of the concrete wall and the heat insulating panel of the present invention, the female screw member and the male screw member for fixing both are formed from a highly rigid material, and heat conduction is performed in a portion embedded in the concrete wall of the male screw member. Since the low-resin resin layer is formed, the female screw member and the male screw member do not become a heat bridge, so it is possible to prevent the occurrence of condensation, and the concrete wall and heat insulation panel can be installed with as few parts as possible. Can be firmly fixed.

  Further, in a preferred embodiment of the concrete wall and heat insulation panel mounting structure according to the present invention, an end portion embedded in the concrete wall of the male screw member is formed with an enlarged diameter portion, which constitutes the enlarged diameter portion. The size of the steel portion is characterized by being larger than the outer diameter of the resin layer other than the enlarged diameter portion.

  By providing the enlarged diameter portion at the end of the male screw member embedded in the concrete wall, the support pressure from the concrete acts on the enlarged diameter portion against the pulling force from the female screw member side. A further anchor effect can be expected by imparting the resistance to the pull-out strength of the male screw member.

  Here, among the steel portion forming the enlarged diameter portion and the resin layer portion on the surface thereof, the planar size (bearing area) of the steel portion serving as the core material is at least a portion other than the enlarged diameter portion. Since the steel part of the expanded part cannot exhibit sufficient bearing resistance unless it is larger than the outer diameter of the resin layer formed on the surface of the steel part (core material), so that such requirements are satisfied, It is necessary to set the size of the expanded portion, the thickness of the resin layer in other portions, and the cross-sectional diameter of the steel portion.

  According to the mounting structure of the concrete wall and the heat insulating panel of the present invention, a larger anchor effect can be expected, so that it is possible to further reduce the number of parts including the female screw member and the male screw member.

  Further, in another embodiment of the concrete wall and heat insulating panel mounting structure according to the present invention, a flange portion is formed at the end of the female screw member on the side not screwed with the male screw member, A female screw member is fitted in the through hole in a posture in which the flange portion is engaged with the surface on the non-contact side, and a hook-like protrusion is formed on the surface of the flange portion that does not face the heat insulating panel. In addition, an outer layer material containing at least mortar is applied to the surface of the heat insulating panel that does not contact the concrete wall.

  For example, the outer heat insulating structure will be described as an example. On the outer surface of the heat insulating panel, a net material for enhancing the adhesion of the mortar to the surface of the heat insulating panel is fixed to the outer wall surface to form an outer layer material such as a mortar layer. . The mortar layer or the like may be a finish coating layer, or a finish coating material may be formed on the outer side of the mortar layer or a tile may be attached. The net material is preferably made of an alkali-resistant material, and examples thereof include a glass fiber mesh (for example, Super Crack Non-Mesh manufactured by Nippon Electric Glass Co., Ltd.), a polypropylene mesh, and a wire mesh.

  In order to firmly fix the female screw member with the heat insulating panel, not only simply fitting into the through-hole, but also providing a flange portion at one end thereof (the end opposite to the side mating with the male screw member). It is effective to engage the heat insulating panel surface. However, in that case, when the outer surface of the flange portion is in a flat state, adhesion to an outer layer material such as mortar is deteriorated.

  Therefore, in the present invention, a flange portion that engages the surface of the heat insulating panel is provided on the female screw member, and by forming a hook-shaped protrusion on the outer surface of the flange portion, that is, the surface that does not face the heat insulating panel, This protrusion is intended to prevent a decrease in adhesion with the outer layer material. Here, the planar view shape of the flange portion can be formed into an arbitrary polygon including a circle and a quadrangle. The hook-shaped protrusion is an arbitrary protrusion (such as a prismatic shape, a pyramid shape, or a conical shape), or an appropriate protrusion such as a protrusion formed on the protrusion having an arbitrary shape. Can be used. According to the protrusion provided with the depression facing upward, the outer layer material fits into the depression, and the adhesion of the outer layer material can be further enhanced. Of course, the protrusion length of the protrusion needs to be adjusted according to the thickness of the outer layer material.

  According to the mounting structure of the concrete wall and the heat insulating panel of the present invention, in addition to being able to firmly fix the female screw member to the heat insulating panel by the flange portion, by forming a hook-like protrusion on the surface of the flange portion, It can prevent that this flange part reduces the adhesiveness of the outer-layer material formed in the outer side of a heat insulation panel, and a heat insulation panel.

  Further, in another embodiment of the concrete wall and heat insulation panel mounting structure according to the present invention, a flange portion is formed at the end of the female screw member on the side not screwed with the male screw member, and an opening is provided on the surface thereof. A surface member having hook-shaped protrusions is interposed between the flange portion and the surface of the heat insulation panel that is not in contact with the concrete wall, with the female screw member passing through the opening. An outer layer material containing at least mortar is applied to the surface of the panel that does not contact the concrete wall.

  Also in the mounting structure of the concrete wall and the heat insulation panel of the present invention, the flange portion that engages the heat insulation panel is formed at the end of the female screw member, but the plane dimension of the flange portion is that the female screw member is engaged with the heat insulation panel. If possible, it is molded to the smallest possible size. By reducing the flange portion, it is possible to increase the efficiency of mounting the female screw member.

  In the embodiment of the mounting structure of the present invention, instead of providing a hook-shaped protrusion on the outer surface of the flange portion, a surface member having an opening and having a hook-shaped protrusion formed on the surface is prepared. The female screw member is passed through, and the flange portion of the female screw member is engaged with the surface of the face member. The face material is fixed in a manner sandwiched between the flange portion of the female screw member and the surface of the heat insulating panel. This face material can also be manufactured from the same material as the net material attached to the heat insulation panel surface.

  According to the mounting structure of the concrete wall and the heat insulation panel of the present invention, since the flange portion can be made small, more parts can be conveyed, particularly when a large amount of female screw members (and male screw members) are used. Further, there is an advantage that the assembly efficiency is increased when the female screw member is assembled to the heat insulation panel. When assembling the female screw member to the heat insulating panel, there is a trouble of penetrating the female screw member through the opening of the surface member, but it is not an operation for reducing the construction efficiency.

  Another embodiment of the concrete wall and heat insulation panel mounting structure according to the present invention is characterized in that an outer layer material is formed in advance on the surface of the heat insulation panel that does not contact the concrete wall.

  The mounting structure of the concrete wall and the heat insulation panel according to the present invention is not a form in which an outer layer material such as mortar is applied to the outside of the heat insulation panel described above, but the outer layer in advance on the outside of the heat insulation panel (the surface not in contact with the concrete wall). It is a mounting structure in which a composite heat insulation panel formed with a material is used. In contrast to the wet insulation method in which mortar or the like is applied afterwards, a method using such a composite insulation panel can also be referred to as a dry insulation method.

  According to the mounting structure of the concrete wall and the heat insulating panel of the present invention, the construction process can be reduced as compared with the wet heat insulating method, so that the construction period can be greatly shortened.

  The fixture for a concrete wall and a heat insulation panel according to the present invention is a fixture for attaching a heat insulation panel to one surface of a concrete wall, and is a female screw member that is fitted into a through hole formed in the thickness direction of the heat insulation panel. And a male screw member made of steel, and a male screw member screwed into the female screw member in a posture in which a part of the male screw member is embedded in the concrete wall, and at least a portion of the male screw member embedded in the concrete wall is The resin layer is formed on the surface.

  For example, a steel male screw member, part of which is embedded in a concrete wall, is combined with a female female screw member fitted in a through hole formed in the heat insulating panel, so that the heat insulating panel and the concrete wall are By being connected by a steel member having high strength, it becomes an attachment that firmly attaches both. Further, among the male screw members constituting the fixture of the present invention, at least a portion embedded in the concrete wall is coated with a resin material as described above, so that the female screw member and the male screw member are interposed from the outside of the heat insulating panel. Since the heat transferred in this way is blocked by the resin layer, the heat is not transferred to the concrete wall, and therefore, the possibility of dew condensation near the boundary between the concrete wall and the heat insulating panel can be extremely reduced.

  Moreover, in a preferred embodiment of the fixture for a concrete wall and a heat insulating panel according to the present invention, an enlarged diameter portion is formed at an end portion embedded in the concrete wall of the male screw member, and the steel constituting the enlarged diameter portion. The size of the manufactured portion is characterized by being larger than the outer diameter of the resin layer other than the enlarged diameter portion.

  By providing an enlarged diameter part at the end embedded in the concrete wall of the male screw member, and by making the size of the steel part constituting the enlarged diameter part larger than the outer diameter of the resin layer of the part other than the enlarged diameter part, It is possible to obtain a fixture having a higher anchoring effect to which the bearing strength is applied.

  Furthermore, in another embodiment of the fixture for a concrete wall and a heat insulation panel according to the present invention, the end of the female screw member on the side not screwed with the male screw member is a side where the female screw member is not in contact with the concrete wall of the heat insulation panel. A flange portion is formed to be engaged with the surface, and a hook-like protrusion is formed on the surface of the flange portion on the side not facing the heat insulating panel.

  By providing a flange portion at the end of the female screw member and engaging the flange portion with the surface of the heat insulating panel, the heat insulating panel and the female screw member can be reliably fixed. In addition, by providing a hook-shaped protrusion having an arbitrary shape as described above on the surface of the flange portion, when an outer layer material such as a mortar layer is applied to the outside of the heat insulating panel, the adhesion between the outer layer material and the heat insulating panel Can be increased.

  As can be understood from the above description, according to the concrete wall and heat insulating panel mounting structure and fixture of the present invention, the female screw member embedded in the heat insulating panel and the male screw member partially embedded in the concrete wall. Are formed of steel members having high rigidity, and both are combined, so that the heat insulation panel and the concrete wall can be firmly attached with as few attachments as possible, and at least the male screw member Since the resin layer is formed on the surface of the steel member embedded in the concrete wall, even if the female screw member and male screw member made of steel transfer heat from the outside of the heat insulation panel, the resin layer Therefore, the possibility of dew condensation near the boundary between the concrete wall and the heat insulation panel can be extremely reduced. Further, according to the concrete wall and heat insulating panel mounting structure and fixture of the present invention, when an outer layer material such as mortar is post-installed on the outside of the heat insulating panel, the flange portion provided at the end of the female screw member By providing the hook-shaped protrusion on the surface, the adhesion between the outer layer material and the heat insulating panel can be enhanced.

  Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view of an embodiment of the female screw member and the male screw member, FIG. 2 is a longitudinal sectional view of the female screw member and the male screw member shown in FIG. 1, and FIG. 3 is a diagram showing the female screw member and the male screw member shown in FIG. FIGS. 4a and 4b are views taken along arrows IV-IV in FIG. 3, respectively. FIG. 5 is a longitudinal sectional view of another embodiment of the fixture. FIG. 6 is a diagram illustrating a construction method of a heat insulation structure including a heat insulation panel and a concrete wall, and is a diagram illustrating a situation before placing concrete.

It is the figure demonstrated, Comprising: The figure explaining the condition after finishing layer construction is each shown. In addition, although the heat insulation structure to show in figure is a structure by a wet heat insulation method, it cannot be overemphasized that the structure by the dry-type heat insulation method in which the appropriate outer-layer material was previously formed in the outer side of the heat insulation panel may be sufficient.

  1 and 2 show an embodiment of a female screw member and a male screw member that form a fixture. The female screw member 1 is formed of a screw groove portion 11 that mates with the male screw member, and a flange portion 12 that is fixed to the screw groove portion 11 by integral molding or welding. On the outer surface of the flange portion, hook-shaped projections 12a, 12a,... Having depressions are formed. On the other hand, as shown in FIG. 2, the male screw member includes a threaded portion 21 that meshes with the thread groove 11 of the female screw member, an anchor portion 22 that is integral with the threaded portion 21, and an end portion of the anchor portion 22.

Is formed. Examples of the resin material used for forming the resin layer 24 include polyvinyl chloride, polyethylene, polypropylene, polyurethane, and epoxy resin. Among them, polyethylene having low thermal conductivity and excellent chemical resistance. Polypropylene is preferred. The thickness of the resin layer is preferably about 0.5 to 2 mm. If it is too thin (less than 0.5 mm), the thermal resistance will be low, making it difficult to effectively block the heat bridge, and if it is too thick (exceeding 2 mm), the anchor may not be firmly fixed in the concrete wall. This is because the desired anchor effect cannot be expected.

  Further, as shown in FIG. 2, the anchor portion is such that the width t1 of the steel member of the enlarged diameter portion 23 is larger than the width t2 of the steel member of the anchor portion other than the enlarged diameter portion and the resin layer. And the part of the steel member and the resin layer of the enlarged diameter part are adjusted. By such adjustment, when the enlarged diameter portion 23 is embedded in the concrete wall, the enlarged diameter portion 23 receives a bearing resistance from the concrete, and the anchor effect of the anchor portion can be enhanced.

  By attaching the fixture 10 to the heat insulating panel in such a posture that the depression of the hook-shaped protrusion 12a in the flange portion 12 faces upward, the mortar enters the depression when the mortar layer described later is applied. And the heat-insulating panel can be further improved in adhesion. In addition, as a planar dimension of the flange part 12, for example, it is a circle with a diameter of about 30 to 100 mm or a rectangle with one side of 30 to 100 mm, and the thickness can be set to about 0.5 to 2 mm.

As the planar shape of the surface member 3, an arbitrary shape such as a polygon such as a circle or a rectangle or an ellipse can be selected. This surface member 3 is also, for example, a circle having a diameter of about 30 to 100 mm, or a square having a side of 30 to 100 mm, and having a thickness of 0.5, similarly to the flange portion 12 when formed in a large size. It can be set to about 2 mm.
