A holding member 10 is provided to strengthen the binding between the heat insulating material 2 and the concrete 5 and hold the heat insulating material.

  The attachment portion 11 is made of a non-ferrous metal such as steel or aluminum, and includes a flange portion 21 and a hollow cylindrical portion 22 formed integrally with the flange portion 21, and a female portion is formed on the inner periphery of the cylindrical portion 22. A screw 23 is formed, and a joining portion 24 is formed on the outer periphery so as to be joined to a prepared hole 17 formed in advance in the composite board 4. The joint portion 24 has, for example, a shape in which a plurality of chevron shapes are arranged on the circumference, so that when the composite portion 4 is driven, the contact area between the outer wall body 3 and the heat insulating material 2 is increased. Furthermore, since the composite board 4 is satisfactorily hooked, the attachment portion 11 can be prevented from coming off. If the joint portion 24 is wedge-shaped as shown in FIG. 3, it becomes easy to be caught on the heat insulating material 2 and the outer wall body 3, and it is difficult to come off, so that the binding between the composite board 4 and the concrete 5 can be further strengthened. it can. Alternatively, the joint portion 24 may be formed by a male screw, and the attachment portion 11 may be screwed to the composite board 4.

  A supporting portion 12 having a male screw 14 formed at one end is inserted into the female screw 23 formed on the inner periphery of the mounting portion 11, and the supporting portion 12 is vertically mounted on the surface of the composite board 4. It is held in a horizontal direction that is at a right angle. The support portion 12 is a rod-like member made of a non-ferrous metal such as steel or aluminum, like the attachment portion 11, and need not be formed of the same material as the attachment portion 11 or the like. Further, the other end protrudes from the heat insulating material 2 when inserted into the mounting portion 11 and has a length sufficient to be embedded in the concrete to be placed. A locking portion 15 is formed for preventing disconnection.

  The locking portion 15 is a protrusion that can prevent the fixing portion 13 from coming off from the other end 16, or has an outer shape larger than a through-hole formed in the center of the fixing portion 13, and is integrated with the support portion 12 body. It may be formed.

  The fixing portion 13 is made of a non-ferrous metal such as steel or aluminum, as with the mounting portion 11 and the like, and is not necessarily formed of the same material as the mounting portion 11 and the like. The fixing portion 13 has a through hole having a diameter substantially the same as the outer shape of the support portion 12 at the center, and is composed of a plate material that is locked at a locking portion 15 formed at the other end of the support portion 12. It may also be a rectangular plate. By doing so, the ring-shaped fixing portion 13 provided at the tip of the support portion 12 is embedded in the concrete 5 to be placed and fixed to the composite board 4, so that the heat insulating material 2 is attached to the outer wall body 3. And the concrete 5 to prevent the dropout, and the fixing portion 13 is hooked on the concrete 5 to prevent the support portion 12 from coming off.

  The fixing unit 13 may be formed integrally with the support unit 12 by bending the tip of the support unit 12 into an L shape. By doing so, the fixing portion 13 formed by bending at the tip of the support portion 12 is embedded in the concrete 5 to be placed and fixed to the composite board 4, so that the heat insulating material 3 is attached to the outer wall body 2. And the concrete 5 to prevent the dropout, and the fixing portion 13 is hooked on the concrete 5 to prevent the support portion 12 from coming off.

  Further, a covering material 19 may be provided on the support portion 12 and the fixing portion 13. The covering material is made of a material that blocks moisture, and may be wrapped with, for example, vinyl chloride or plastic tape. By covering the support part 12 and the fixing part 13 with the covering material 19 in this way, even if condensation occurs due to a heat bridge, the intrusion of moisture into the support part 12 and the fixing part 13 can be blocked by the covering material 19, so that support is provided. Corrosion of the portion 12 and the fixing portion 13 can be prevented, and the composite board 4 and the concrete wall 1 can be maintained well even over time.

  In order to install the holding member 10 on the composite board 4, a through hole 18 is formed in advance on the surface of the outer wall body 3 at a predetermined interval from the installation position of the spacing holder, and a mounting portion is provided in the through hole 18. 11 is inserted into the heat insulating material into the lower hole 17 formed coaxially with the through hole 18, and the joining portion 24 formed on the outer periphery of the attachment portion 11 reaches the inside of the heat insulating material 2 and joins. The mounting portion 11 is fixed to the composite board 4. On the other hand, the fixing portion 13 is mounted from one end of the support portion 12, and the fixing portion 13 is held by a locking portion 15 formed at the other end 16 of the support portion 12. In order to limit the movement of the fixing unit 13, a stopper (not shown) may be inserted from one end of the support unit 12.

  In this way, the support part 12 provided with the fixing part 13 is inserted into the female screw 23 formed on the inner periphery of the attachment part 11 by screwing the male screw 14 formed on one end of the support part 12. The holding member 10 is installed on the composite board 4. At this time, the other end 16 of the support portion 12 around which the fixing portion 13 is wrapped protrudes from the heat insulating material 2.
