Description

  The present invention relates to a method for attaching a decorative plate to an outer heat insulating material for both a formwork and a hook for attaching to an outer wall used in the outer heat insulating material of a concrete building, in order to securely and safely attach a heavy decorative material. This relates to the member.

Conventionally, when an outer wall is attached to the outside using an outer heat insulating material, for example, a reinforcing material and a heat insulating material are bonded in advance to a concrete panel and integrally formed, and this is used as a dam plate of a formwork and the other weir. An arrangement is known in which concrete is placed in a formwork with a predetermined distance from a plate (see Patent Document 1). In this method, a reinforcing material and a heat insulating material are bonded in advance to a concrete panel serving as an outer wall, and the subsequent man-hours are reduced. In the reinforcing material and the concrete panel, a through hole for a shaft tie of a foam tie is provided. It is necessary to provide a repair work for filling the through-hole with mortar after removing the form tie and the thick side ends of the formwork. Furthermore, since the lateral end material is directly laid on the concrete panel serving as the outer wall, the control panel may be damaged. In addition, since the outer wall attached to the outside of the heat insulating material is usually heavy, an embedded fitting for the outer wall that can withstand the weight is embedded at the time of making the formwork, and after placing the concrete and removing the formwork, A support metal part of which protrudes from the surface of the heat insulating material is connected to the embedded metal part, and an outer wall is hooked on the protruding part of the support metal part.

Further, the abutment tool in the outer wall mounting latch member is a disc body having a required thickness as a whole, and a connection portion for joining the connection tool and the mounting member is provided at the center thereof;
Furthermore, the separator is a deformed steel bar or a bar that prevents the surface from coming off.
Is included.

  The gist of the outer wall mounting latch member according to the present invention is a connector that can be screwed and connected to a separator for a formwork, the length of which is substantially equal to the thickness of the heat insulator for formwork, The whole fixed to the end of the connection tool consists of an outer wall support pad that is a disc body, or the connection tool and a latching channel that is fixed to the connection member with a double nut and horizontally suspended. It is to become.

According to the decorative plate mounting method of the outer heat insulating material for both formwork and the latching member for mounting the outer wall according to the present invention,
Even if a heavy outer wall material is attached to the heat insulating material that also serves as a formwork, the heat insulating material made of foamed resin is not burdened, and the outer wall material can be safely and reliably supported by the retaining member. In addition, since the retaining member is attached using a separator for a formwork, there is no need for a new part and cost is reduced, and furthermore, the hole after the foam tie and its shaft foot are removed is used. In the conventional method, a hole is formed in the heat insulating material at the position of the embedded metal fitting. However, in the present invention, such an operation is unnecessary and the number of mounting steps can be reduced.

  As shown in FIG. 1, the decorative plate mounting method for an external heat insulating material for formwork according to the present invention can be screwed and connected to a separator 2 for formwork, and its length is the thickness of the heat insulating material 3 for formwork combined. An outer wall mounting latch member 1 is formed in advance, which includes a connecting tool 1a substantially equal to the connecting tool 1a and an outer wall supporting pad 1c fixed to the end 1b of the connecting tool 1a.

  Next, as shown in FIGS. 2-A and 2-B, one of the dam plates 3 and 9a on both sides for the concrete wall mold 9 for external heat insulation is made of foamed resin on the outer surface. As a mold and heat insulating material in which a U-shaped metal reinforcing material 4 having a U-shaped cross section is provided in the vertical direction, a separator 5 and a cone 5a are interposed between the both weir plates 3 and 9a to form ties 6, The side end thick material 7 is fixed by the shaft foot 6a and the nut 6b, and the mold 9 for the concrete wall 8 is assembled.

  The separator 5 and the foam tie 6 are disposed between the reinforcing members 4 provided in place of the vertical end thick members as shown in FIG. Further, as shown in FIG. 2-A (B), the separator 5 is made of a deformed steel bar or a metal having irregularities on the surface so that it is not pulled out after removing the formwork 9 and the side end thick material 7 and the like. It is a rod that prevents falling out.

  Next, the concrete wall 8 in which fresh concrete is cast on the mold 9 and hardened is formed. Thereafter, as shown in FIG. 3, the foam tie 6, the shaft foot 6a, and the nut 6b are removed, and the lateral end thick material 7 is removed.

  Next, as shown in FIG. 4, the connecting tool 1a of the outer wall mounting latch member 1 is inserted and embedded in the hole 3a after the foam tie 6 and the like are removed in the mold / heat insulating material 3. Connect to separator 5.

  Then, as shown in FIG. 5, the mounting member 2 for mounting the outer wall is fitted and fixed to the connecting portion 1 d of the stopper 1 c of the latching member 1 for mounting the outer wall. The attachment member 2 is entirely made of metal L-shape, and a screw portion that is screwed into the connection portion 1d of the abutment tool 1c is engraved on one end portion 2a.
