JP 2004-251031 A Published in August 2004 “Abstracts of Architectural Conference of the Architectural Institute of Japan (Hokkaido)” on pages 709 and 710 “Empirical Study of RC External Thermal Insulation Method (Part 1 Outline of Method)”

  By the way, the above-described conventional barrel edge mounting bracket is configured to securely screw the barrel edge receiving plate into the male screw portion of the large-diameter bracket body without rattling.

  However, since the bracket generally supports a heavy exterior material at its tip, the bracket tends to bend or rotate in the axial direction when subjected to earthquakes or vibrations. There is also a problem that rotation occurs in the trunk edge receiving plate, and distortion or damage occurs in the trunk edge, the exterior material, and the screw that joins them. In order to prevent such a state, it is necessary to suppress bending deformation and rotation of the bracket, and it is necessary to increase the diameter of the bracket and to provide a large and rigid ridge to suppress rotation of the root portion. Such a solution is uneconomical, and improvement of earthquake resistance by rational means has been a major issue.

  Also, if there is unevenness on the surface of the chassis wall, it is difficult to fix the bracket body vertically to the chassis wall, the bracket body is mounted in an inclined state, and the surface of the trunk edge receiving plate attached to this bracket body is also There is a problem that the surfaces of the plurality of trunk edge receiving plates that are inclined and cannot be aligned on the same plane. If construction is performed with the surface direction of the plurality of trunk edge receiving plates running across the trunk edges being uneven, it may cause looseness or distortion in the mounting state of the trunk edges, or the accuracy of the finished surface of the exterior material may be reduced. . The barrel edge attached in a loose or distorted state may cause unexpected deformation or damage to the barrel edge or its periphery when subjected to external force such as vibration or thermal stress. For this reason, it is necessary to perform a ground treatment such as chipping or mortar coating on the wall surface of the housing prior to the mounting of the body edge mounting bracket, and there is a problem that a great deal of labor is required for the construction. Especially in the renovation work, the state of the wall of the frame is various, and this problem is remarkable.

  The present invention has been made in view of the above-mentioned conventional problems, and provides an outer wall structure of a building excellent in earthquake resistance, and a plurality of bridges that hang a trunk edge even when the bracket body is attached with a slight inclination. It is intended to make it possible to easily match the surface of the body edge receiving plate on the same surface, and to cope with various construction conditions without applying ground treatment such as chipping or mortar coating. .

  For this purpose, the present invention has an anchor fixing portion fixed to a building wall of a building on one end side of a bowl-shaped bracket body, and a barrel projecting outward from the bracket body on the other end side of the bracket body. A trunk mounting bracket to which an edge receiving plate is attached, wherein the trunk mounting plate is attached so as to be tiltable around the bracket body with respect to a direction orthogonal to the central axis of the bracket body. Is to provide.

The bracket for mounting a trunk edge according to the present invention has a male screw part at the other end of the bracket body, and a female screw part provided through the center part of the trunk edge receiving plate. The plate is attached so as to be able to tilt around the bracket body by screwing the female screw part into the male screw part with play.
A ball is rotatably held at the other end of the bracket body, and the trunk edge receiving plate is attached to the ball so that it can be tilted around the bracket body.
The trunk edge receiving plate is attached so as to be able to tilt around the bracket body in the range of 1 to 10 degrees above and below the direction perpendicular to the central axis of the bracket body,
Is included as a preferred embodiment thereof.

  Further, according to the present invention, the anchor fixing portion of any one of the above-mentioned body edge mounting brackets is fixed to the outer surface side of the building wall of the building, and the bracket body is connected to the other end side of the bracket body of the body edge mounting bracket. A barrel edge receiving plate projecting outward from the bracket body is attached so as to be able to tilt around the bracket body with respect to a direction orthogonal to the central axis of the bracket body. It also provides an outer wall structure of a building characterized in that a secondary trunk edge or an exterior material to which an exterior material is attached is attached to the body edge.

In the building outer wall structure according to the present invention, the heat insulating material is attached to the building wall surface of the building through the bracket main body, and the other end of the bracket main body protrudes outward from the heat insulating material. Attached to the side,
The insulation is sandwiched between the insulation retainer plate attached to the bracket body and the housing wall;
Is included as a preferred embodiment thereof.

  The bracket for mounting the trunk edge according to the present invention is particularly capable of tilting by 1 to 10 degrees since the trunk edge receiving plate can tilt around the bracket body with respect to the direction orthogonal to the central axis of the bracket body. If this is the case, an axial bending deformation or rotation of the root part of the bracket due to earthquake or vibration will occur, and even if the tip of the bracket is inclined, the trunk edge receiving plate can keep its original surface without being affected by it. In addition, it is possible to prevent distortion and damage from occurring in the trunk edge and the exterior material. Further, even if the bracket body is attached with a slight inclination, the surfaces of the plurality of trunk edge receiving plates over which the trunk edges are spanned can be easily aligned on the same plane. Therefore, according to the outer wall structure of a building according to the present invention using this trunk edge mounting bracket, an outer wall structure having excellent earthquake resistance can be obtained. In addition, it is possible to securely attach the trunk edge in a stable state without applying a ground treatment such as chipping or mortar coating, and to obtain a finished surface of a good exterior material. Moreover, it is possible to easily cope with repair work in which the state of the frame wall is not constant.

  Based on FIGS. 1-3, the outer wall structure of the building which concerns on an example of this invention using the trunk | drum mounting bracket which concerns on an example of this invention, and this bracket for brackets is demonstrated.

  FIG. 1 is a side view showing a trunk mounting bracket according to an example of the present invention, FIG. 2 is a perspective view in the middle of construction showing a part of an outer wall structure of a building according to an example of the present invention, and FIG. It is sectional drawing which shows a part of building outer wall structure which concerns on an example of this invention.

  First, the trunk edge mounting bracket will be described. In FIG. 1, 1 is a bracket body, 2 is an anchor portion, 3 is a heat insulating material pressing plate, and 4 is a trunk edge receiving plate.

  The bracket body 1 may be made of plastic when heat insulation is important, but is generally made of a metal bowl such as steel or stainless steel, and has a female anchor as an anchor fixing portion at one end side central portion. A screw portion 5 is provided, and a male screw portion 6 is provided on the outer peripheral surface on the other end side. Moreover, the tool receiving part 7 which makes the shape of the head part of a volt | bolt is provided in the other end side edge part in which the external thread part 6 was provided. The tool receiving portion 7 can be provided as a concave portion in which a male hex wrench or the like fits, for example, at a location where a tool such as a wrench used for screw tightening is connected.

  A flange portion 8 that protrudes outward is provided at an intermediate portion of the bracket body 1. Further, on the anchor portion 2 side of the flange portion 8, a recess portion 9 is formed at a position surrounding the bracket body 1, and one or a plurality of through holes 10 are formed at a position corresponding to the recess portion 9. ing. The role of the recess 9 and the through hole 10 will be described later.

  The anchor portion 2 has a male screw portion 11 on one end side, and a diameter-increased head portion 12 whose diameter is gradually increased toward the end portion on the other end side. A hook-like anchor pin 14 provided with a stopper 13 is provided in the vicinity of the end of the portion 11 on the enlarged diameter head 12 side. Further, an anchor ring 16 having a slit 15 cut in the axial direction from an end edge on the enlarged diameter head 12 side is fitted between the stopper 13 and the enlarged diameter head 12 so as to be slidable in the axial direction. Yes.

  As shown in FIG. 3, the anchor portion 2 is driven into a hole 18 formed on the outer surface of the housing wall 17, and then the female screw portion 5 of the bracket body 1 is attached to the male screw portion 11 of the anchor portion 2. After the flange 8 of the bracket body 1 abuts against the outer surface of the housing wall 17 with a wrench or the like that is screwed and connected to the tool receiving portion 7, the bracket body 1 is further tightened to fix the bracket body 1 to the housing wall 17. Is. That is, when the bracket body 1 is further tightened after the collar portion 8 abuts on the outer surface of the housing wall 17, the anchor pin 11 is gradually drawn toward the bracket body 1, and the enlarged head portion 12 enters the anchor ring 16. The anchor ring 16 is strongly engaged with the inner wall of the hole 18. The diameter of the anchor ring 16 is slightly smaller than the diameter of the hole 18, and only the convex piece 16 a provided on the surface of the anchor ring 16 is configured to contact the inner wall surface of the hole 18. The piece 16a has a structure in which the resistance is small in the driving direction but the resistance is large in the pulling-out direction. Therefore, when the anchor pin 11 is pulled toward the bracket body 1, only the anchor ring 16 does not move, and the diameter-expanded head 12 can enter the anchor ring 16 and expand the diameter.

  Even after the flange portion 8 of the bracket body 1 comes into contact with the outer surface of the housing wall 17, the bracket body 1 is further tightened so that the enlarged-diameter head enters the anchor ring and the anchor portion 2 is fixed. That is, the angle of the anchor portion 2 is corrected to a state perpendicular to the housing wall 17 until the completion of tightening regardless of the angle of driving into the hole 18.

  Further, when the bracket body 1 is fixed to the anchor portion 2 in a state in which the flange portion 8 is in contact with the outer surface of the housing wall 17, the bracket portion 1 receives an external force in the direction perpendicular to the axis such as the weight of the exterior material. This has the effect of improving the degree of fixation of the bracket and making it difficult for the bracket base to rotate. Further, by providing the flange portion 8, it is possible to easily attach the bracket body 1 with a certain length protruding from the housing wall 17. If the anchor portion 2 is of a type that opens at the end with driving and exhibits an anchor effect, even a craftsman with a low skill level can perform construction, but the position of the anchor portion 2 is fixed when driven. Therefore, if it is driven obliquely with respect to the housing wall 17, when the bracket body 1 is tightened and fixed later, troubles such as the flange portion 8 not contacting the housing wall 17 or the anchor portion 2 being broken are likely to occur. .

  The heat insulating material retainer plate 3 is a plate-like material having a female screw portion 19 penetrating in the center, and is projected around the bracket main body 1 by screwing the female screw portion 19 with the male screw portion 6 of the bracket main body 1. It is to be attached in the state. As shown in FIG. 3, the heat insulating material retainer plate 3, as shown in FIG. 3, penetrates the bracket body 1 fixed to the housing wall 17 by the anchor portion 2 and presses the heat insulating material 20 pressed against the outer surface of the housing wall 17 with the housing wall 17. It is something to be sandwiched between. The heat insulating material retainer plate 3 can be made of metal, but is preferably made of synthetic resin in order to suppress heat loss. In the case of using a synthetic resin, it is also preferable to use the following method without providing the female screw portion 19. The thickness of the insulating material retainer plate 3 in contact with the bracket body 1 is substantially the same as the space between the screw threads provided in the male threaded portion 6 of the bracket body 1, and the diameter of the hole through which the bracket body 1 in the center portion passes. Is slightly larger than the root diameter of the threaded portion of the male threaded portion 6 and smaller than the thread diameter of the threaded portion of the male threaded portion 6. If comprised in this way, the heat insulating material retainer board 3 can be mounted | worn by the operation | work inserted in the bracket main body 1, and it is easier than the operation | work which tightens a screw, and the extent to which the heat insulating material retainer plate 3 presses the heat insulating material 20 can also be adjusted easily. Moreover, the heat insulating material pressing plate 3 can be omitted depending on the mounting form of the heat insulating material 20 as well as the case where the heat insulating material 20 is not provided.

  The trunk edge receiving plate 4 is a plate-like material having a female screw portion 21 penetrating in the center, and the female screw portion 20 is screwed into the male screw portion 6 of the bracket body 1 after the heat insulating material pressing plate 3. The bracket body 1 is attached in a state of overhanging. As shown in FIG. 3, the trunk edge receiving plate 4 serves as an attachment portion of the trunk edge 22, and is usually made of metal. Further, the attachment position of the trunk edge receiving plate 4 can be adjusted by adjusting the screwing position of the bracket body 1 to the male screw portion 6.

  The female thread portion 20 of the trunk edge receiving plate 4 is formed on the inner surface of a cylindrical piece 4b obtained by squeezing the central portion of the trunk edge receiving plate 4 into a cylindrical shape. The trunk edge receiving plate 4 is a steel plate having a thickness of about 1.6 to 3.2 mm, and the thickness of the cylindrical piece 4b is reduced by drawing and becomes a thickness of 1/2 to 2/3. . Therefore, even when tilting beyond the initially set value occurs in the trunk edge receiving plate 4, the tilting angle greater than the set angle is absorbed by deformation of the cylindrical piece 4b without causing deformation in the trunk edge receiving plate body 4a. It is possible to prevent the body edge receiving plate main body 4a, the body edge 22, the exterior material 24, and the screws connecting them from being distorted or damaged. Unlike the polygonal shape, the cylindrical piece 4b does not concentrate stress at a specific location when it is deformed, and has excellent deformability and durability. In order to obtain this effect, it is necessary to appropriately select the length of the cylindrical piece 4b. When the length of the cylindrical piece 4b is long, the tiltable range is small, and when the length is short, the length is large. The length is preferably 2 to 10 threads, and more preferably about 3 to 6 threads.

  In particular, the body edge receiving plate 4 in this example is such that the female screw portion 19 is loosely screwed with play to the male screw portion 6 of the bracket body 1, and is shown by a one-dot chain line in FIG. As can be seen from the above, the bracket body 1 can be tilted around the bracket body 1 within a range of 1 to 10 degrees in the vertical direction with respect to the direction orthogonal to the central axis of the bracket body 1. Therefore, even when the bracket body 1 is attached in a slightly tilted state, by tilting the trunk edge receiving plate 4, the surface of the trunk edge receiving plate 4 can be aligned vertically and on the same plane. Even when the bracket body 1 rotates or bends due to vibration, the trunk edge receiving plate 4 does not rotate, and distortion and damage of the trunk edge 22 and the exterior member 24 can be prevented. If the tilt angle is in the range of 1 to 10 degrees, the object of the present invention can be achieved. When the tilt angle of the trunk edge receiving plate 4 is less than 1 degree, it is difficult to sufficiently correct the inclination of the bracket main body 1 when the bracket main body 1 is rotated or bent due to an earthquake or vibration. If the angle exceeds 10 degrees, the trunk edge receiving plate 4 becomes unstable and the workability deteriorates.

  The distance between the surface of the bracket body 1 that contacts the housing wall 17 and the trunk edge receiving plate 4 is generally 20 to 150 mm, and 40 to 150 mm when the heat insulating material 20 is attached to the surface of the housing wall 17. Generally, 20-100 and 40-100 mm are used, respectively. The outer diameter of the bracket body 1 is determined by the distance between the surface in contact with the housing wall 17 and the trunk edge receiving plate 4, the weight of the assumed exterior member 24, seismic force, vibration load, and the like. 8-24 mm, more generally 10-20 mm is used.

  Next, the outer wall structure of the building will be described.

  In particular, as shown in FIG. 3, a hole 18 is formed on the outer surface side of the building wall 17 of the building, and the anchor portion 2 is driven into the hole 18 from the enlarged head 12 side.

  The hole 18 may have a diameter that is slightly larger than the diameter-enlarged head 12 of the anchor portion 2 and has a diameter with which the convex piece 16a properly contacts. When injecting the adhesive 21 such as mortar, the diameter of the rear end side (opening side) of the drilling hole 18 should be larger than the diameter of the front end side (bottom side) to facilitate the injection of the adhesive 21. preferable.

  A female screw portion 5 (see FIG. 1) of the bracket body 1 is screwed into the male screw portion 11 of the anchor portion 2. As described above, this screwing is performed by further tightening the bracket body 1 even after the flange portion 8 of the bracket body 1 abuts against the outer surface of the housing wall 17 with a wrench connected to the tool receiving portion 7. ing. As a result of this tightening, the anchor pin 11 is gradually drawn, and the enlarged diameter head 10 enters the anchor ring 16 to expand the diameter, and the anchor ring 16 strongly engages with the inner wall of the drilling hole 18 to fix the anchor portion 2. Is fixed in the hole 18 and the bracket body 1 is attached to the anchor portion 2.

  When injecting the adhesive 23 into the drilling hole 18, it is preferable to inject a sufficient amount of the adhesive 23, but when an excessive amount of the adhesive 23 is injected, the bracket body is inserted into the male screw portion 11 of the anchor portion 2. When one female screw part 5 (see FIG. 1) is screwed in, excess adhesive 23 overflows from the hole 18 and prevents the tight part 8 from adhering to the housing wall 17. . The recess 9 and the through hole 10 (see FIG. 1) provided in the flange 8 are for preventing this. If these are provided, the adhesive 23 overflowing from the hole 18 is accommodated in the recess 9, and the adhesive 23 that cannot be accommodated in the recess 9 is discharged from the through hole 10. It is possible to prevent the flange portion 8 from being pushed up by the overflowing adhesive 23 and hindering the adhesion of the flange portion 8 to the housing wall 17. Further, by visually observing that the adhesive 23 flows out of the through hole 10, it can be confirmed that the adhesive 23 is sufficiently filled.

The bracket body 1 is fixed to the housing wall 17 in a large number as described above, and the heat insulating material 20 is pressed through the bracket body 1 on the outer surface of the housing wall 17 to which the bracket body 1 is fixed. ing. This heat insulating material 20 is sandwiched between the housing wall 17 by a heat insulating material pressing plate 3 screwed into the male screw portion 6 of each bracket body 1. As the heat insulating material 20, synthetic resin heat insulating materials such as phenol foam, polystyrene foam, and rigid urethane foam, and fiber heat insulating materials such as glass wool can be used. Among them, a phenol foam heat insulating material having a compressive strength at a strain of 5% of about 10 to 20 N / cm ^{2 and} using a polyester nonwoven fabric as a surface material is most suitable. When the heat insulating material 20 penetrates the bracket main body 1, the heat insulating material 20 can be pierced without drilling the heat insulating material 20, and can be easily and stably provided with the heat insulating material pressing plate 3 having a diameter of about 3 to 10 cm. Can be fixed to. If the heat insulating material 20 or the surface material is harder, it is necessary to process a pilot hole. If the heat insulating material 20 is softer, the peripheral portion is greatly collapsed when pierced, and repair is required, or between the heat insulating material pressing plate 3 and the heat insulating material 20 Therefore, it is difficult to generate an appropriate repulsive force, so that the heat insulating material 20 is not easily held and misalignment is likely to occur. In order to prevent displacement of the heat insulating material retainer plate 3, special means are required such as fixing the heat insulating material retainer plate 3 and the bracket body 1 with screws and further performing a loosening prevention treatment such as a double nut.

  A barrel edge receiving plate 4 is further screwed onto the male threaded portion 6 of each bracket body 1, and a trunk edge 22 spanning between the plurality of trunk edge receiving plates 4 is connected to the trunk edge receiving plate 4. It is attached with screws. As the trunk edge 22, a hat-type material in which both ends of a long metal material having a downward U-shaped cross section are bent outwardly to form a hook-shaped protrusion can be used. The trunk edge 22 in this example is made of this hat-type material, and is attached by fixing the hook-shaped protrusion to the trunk edge receiving plate 4 with a screw or the like. Further, an exterior material 24 is attached to the top edge of the hat-shaped material body edge 22 with screws or the like.

  In particular, in the present invention, since the trunk edge receiving plate 4 can tilt with respect to the bracket body 1, each trunk edge receiving plate 4 to which the trunk edge 22 is attached even when the bracket main body 1 is inclined and attached. The surfaces can be aligned on the same plane. Further, the outer peripheral material 24 or the secondary outer peripheral edge is fastened with a means such as a screw or a bolt to straddle the plurality of parallelly disposed outer peripheral edges 22, so that each of the inner peripheral edges 22 becomes the outer peripheral material 24 or the secondary material. It is corrected to the same surface as the torso surface. Therefore, it is easy to stabilize the attachment state of the trunk edge 22, and the finished surface of the exterior member 24 is also good.

  The trunk edge receiving plate 4 is preferably attached at a position away from the heat insulating material 20 in order to secure a sufficient ventilation space between the heat insulating material 20 and the exterior material 22. Moreover, although the trunk | rim edge 22 is normally attached to the vertical direction, it can also be attached to a horizontal direction. Further, instead of attaching the exterior material 22 to the body edge 22, a secondary body edge (not shown) is attached in a direction intersecting the body edge 22, and the exterior material 22 is attached to the secondary body edge. it can.

  Next, based on FIG. 4, a trunk edge mounting bracket according to another example of the present invention will be described.

  FIG. 4 is a side view showing the trunk edge mounting bracket according to another example of the present invention in a state where the trunk edge and the exterior material are attached. In FIG. 4, the same reference numerals as those in FIGS. 1 to 3 indicate similar members, and similar reference numerals indicate similar members.

  The bracket body 1 'in this example is the same as the example in FIG. 1 in that it has an anchor portion 2 on one end side, but a bearing-like ball 25 is rotatably held at the end portion on the other end side. Yes. Further, the trunk edge receiving plate 4 ′ (similar to the trunk edge receiving plate 4 in FIG. 1 except that the female screw portion 21 in FIG. 1 is not provided) is attached to the ball 25 with screws or the like. By rotating 25, it is possible to tilt around the bracket body 1 'in the range of 2 to 10 degrees up and down with respect to the direction orthogonal to the central axis of the bracket body 1'.

  In the case of this example, since the tilt of the trunk edge receiving plate 4 ′ is brought about by the bearing-like ball, a smoother tilt is possible.

  The trunk edge 22 shown in FIG. 4 uses the hat-type material described above upside down from the example shown in FIGS. 2 and 3, and the top is attached to the bracket body 1 ′ (ball 25). And the hook-shaped protruding portion is the attachment side of the exterior member 24. Such a use mode of the hat-type material can be applied to the trunk edge mounting bracket shown in FIG. 1, and when the seam of the exterior material 24 is located on the trunk edge 22 as shown in FIG. 4. It is effective for.
