Description

  The present invention relates to a technique for improving the efficiency of exterior material attaching work and reducing the number of parts in an outer heat insulating method.

2. Description of the Related Art Conventionally, in a building such as a reinforced concrete structure or a reinforced steel concrete structure, a technique is known in which concrete is driven using a heat insulating board that also serves as a formwork in order to efficiently insulate a concrete wall surface. (For example, see Patent Document 1 and Patent Document 2.)
In such a technique, in order to keep the concrete thickness constant, a concrete is placed by placing a separator between the heat insulation board and the panel material, and then placing the exterior material on the outside. The exterior material construction to be attached is performed separately.

  An example of this construction will be described. As shown in FIG. 9A, the outside of the heat insulating material 51 is supported by the panel form 52 and a separator 53 is provided between the other side panel forming frame 52 and the heat insulating material 51. After maintaining a constant distance between the two, concrete 54 (see FIG. 9B to be described later) is driven between the heat insulating material 51 and the panel panel 52 on the other side for curing. ing. At this time, a through-hole through which the tip of the separator 53 can be inserted is formed in the panel form frame 52 on the side opposite to the heat insulating material 51, and a part of the tip of the separator 53 projects to the outside. A foam tie 63 is fastened to the tip of the separator 53 and clamped, and the tip of the separator 53 on the opposite side is connected to the separator connecting bracket 60. In addition, a shaft leg 64 is also connected to the separator connecting metal 60 through a through hole formed in the heat insulating material 51 and the panel mold frame 52, and one end side of the shaft leg 64 is also connected from the through hole of the panel mold frame 52. The foam tie 63 is fastened to the outside and a mold tie 63 is fastened to the mold. Then, as shown in FIG. 9 (c), when the curing of the concrete is completed, the panel form 52 is disassembled, and then the concrete 54 is passed through the heat insulating material 51 to a place different from the place where the separator connection fitting 60 is present. A mounting hole 55 for embedding the insert hardware is drilled in. An insert metal piece 56 is embedded in the attachment hole 55, and an L-shaped fixing fitting 57 is attached thereto, and an exterior material 59 is attached to a lip groove steel 58 fastened to the fixing fitting 57.

The separator connecting bracket 60 connected to the separator 53 at the time of placing the concrete is fitted into a resin cone member 61 and a fitting hole 61h of the cone member 61, as shown in FIG. The insertion fitting 62 is integrated, and the female screw hole 62n formed in the insertion fitting 62 is screwed into the male screw portion of the separator 53 on one end side, and at the same time the foam tie 63 is attached to the other end side. It is constituted as a female screw hole 62n that penetrates the shaft leg 64 for use. Then, after the concrete 54 is placed, when the mold 52 is disassembled, the foam tie 63 and the shaft leg 64 are also removed, and the through hole of the heat insulating material 51 is closed as necessary. It is embedded in the concrete 54 together with the separator 53. For this reason, for example, a connecting member such as a screw rod may be screwed into the female screw hole 62n of the insertion fitting 62 and the fixing bracket 57 for attaching the exterior material may be attached thereto. Since the diameter of the hole 62n is small (normal separator diameter is 5/16 inch), for example, depending on the type of the exterior material 59 such as tile finishing or molded cement board, the weight of the exterior material becomes heavy, and the insertion fitting 62 or the connecting member In general, the mounting hole 55 is separately drilled and the fixing bracket 57 is attached by using a strong insert metal 56.

  Even with such a configuration, it is possible to connect a connecting member having a diameter larger than the separator diameter to the insertion fitting when constructing the exterior material, and it is necessary if a fixing member for fixing the exterior material is fastened to the connection member. Strength is ensured.

  As described above, in the past, for the purpose of keeping the concrete thickness constant in formwork, it is possible to fix the exterior material by effectively utilizing the separator connecting bracket that was wasted after placing the concrete. As a result, the number of parts can be reduced and work efficiency can be improved.

  At this time, if the insertion fitting that fits the cone member is extended from the flat surface portion to the front as the separator connection fitting, and the overhanging portion is provided, the fixing fitting for mounting the exterior material can be directly fastened to the insertion fitting. If the insertion bracket is provided with a female screw hole for connecting a shaft leg and a female screw hole for connecting a large diameter connecting member, a fixing bracket for mounting an exterior material is indirectly attached to the large diameter connecting member. It can be fastened, and in any case, it can be effectively supported even if the weight of the exterior material increases.
