Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic sash used as a single window type window, in particular, to a precast concrete board (hereinafter referred to as "PC board") or to an opening of a concrete frame. The present invention relates to a plastic sash having a slide anchor suitable for being attached or directly attached to the outer wall concrete of a building.

[0002]

2. Description of the Related Art A PC plate with an aluminum sash formed by driving concrete around an aluminum sash (hereinafter referred to as "aluminum sash") is a so-called P
Also known as C-cast aluminum sash. This PC board with an aluminum sash is arranged with aluminum sashes around it.
It is set by setting it on a C-plate curing bed, fixing it, placing a heavy sash holding frame on the aluminum sash, placing concrete around them, and then performing curing to form.

By the way, metal sashes such as aluminum sashes and steel sashes are subject to dew condensation and mold.
In order to solve such problems, plastic sashes such as polyvinyl chloride (PVC) and FRP have been used in recent years because of problems such as generation of radio interference and poor heat insulation.
PC sashes made of plastic, polycarbonate, etc. are widely used.
The adoption of boards is also being considered.

[0004]

However, since the coefficient of thermal expansion of concrete is different from that of the plastic sash, the method of forming a PC plate with an aluminum sash is used to form a PC plate with a plastic sash, or a building. When directly attached to the outer wall concrete, various problems occur as described in detail below.

A vinyl chloride resin sash, which is a typical example of a plastic sash (hereinafter, referred to as "PVC sash" as appropriate), shows that when the PC plate with the PVC sash is formed, the PVC sash reacts when the concrete is solidified. Elongation due to heat, shrinkage due to temperature drop at the end of concrete pouring, or temperature rise during steam curing (30-80
C.) and shrinkage due to a temperature drop accompanying the completion of steam curing, various stresses are continuously applied to the PC plate and the PVC sash until the PC plate with the PVC sash is formed. As a result, the concrete on the PC board cracked,
There is a problem that cracks, swelling of the surface, and distortion occur, and at the same time, the vinyl chloride sash has a problem that distortion occurs.

When the PC board with the vinyl chloride sash is attached to the opening of the outer wall of the building, it is exposed to solar radiation and repeatedly undergoes thermal expansion and contraction for a long period of time. There is a problem that cracks, cracks, swelling of the surface, distortion, partial peeling occur, and distortion occurs in the vinyl chloride sash.

In addition, since the PC board with the vinyl chloride sash has poor adhesion and adhesion between the vinyl chloride sash and concrete,
Since it cannot be securely held on the plate or the like, it is necessary to fix the PVC sash to the PC plate or the like with an anchor in order to prevent the plate or the like from coming off.

In this case, if a plurality of fixed anchors are fixed to the vinyl chloride sash and the vinyl chloride sash is attached to the PC plate to form an integral structure, the vinyl chloride sash to which the fixed anchor is fixed also has a coefficient of thermal expansion with that of concrete. Affected by the difference.

As a result, there is a problem that the PC board is damaged, the fixed anchor is damaged or disengaged, or the vinyl chloride sash is deformed due to thermal expansion and thermal contraction of the vinyl chloride sash. Further, if the fixed anchor is damaged, the PVC sash will be damaged when the PC plate with the PVC sash is being formed or if the PC plate is used by being attached to a building.
There is a problem that it may come off from the C plate or the like.

Further, when the PVC sash is directly attached to the outer wall concrete of a building, a plurality of fixed anchors are fixed to the PVC sash, and the fixed anchors are directly attached to the outer wall concrete by fixing them with bolts or the like. But,
If the vinyl chloride sash is exposed to solar radiation and repeats thermal expansion and contraction for a long period of time, there is a problem that the outer wall concrete will be damaged, the fixed anchor will be damaged, will come off, or the vinyl chloride sash will be deformed. There is a problem that if the building is damaged, the PVC sash may come off from the building. The above problems are not limited to aluminum sashes, but are common to other plastic sashes.

Therefore, the present invention solves the above-mentioned problems, and when the plastic sash is attached to the PC board so that both are formed as an integral structure, or the plastic sash is attached directly to the outer wall concrete. In this case, even if the plastic sash expands or contracts due to the temperature change due to thermal expansion or contraction, the PC plate or outer wall concrete will not be damaged, the anchor will not be damaged, and the plastic sash will be distorted. It is an object to provide a plastic sash having a slide anchor that is prevented.

[0012]

In order to achieve the above object, the plastic sash of the present invention has a metal rail fixed to the outer surface of the frame material, and a metal which moves in the longitudinal direction while being held by the rail. A slide anchor made of metal is provided, and the slide anchor includes a base that slides while being held by the rail, an intermediate member provided on the base, and an intermediate member provided on the intermediate member. And an anchor member attached so as to be rotatable and fixable. Further, if necessary, a fixed anchor is fixed to the outer side surface of the frame material of the plastic sash substantially at the center in the longitudinal direction.

[0013]

In the plastic sash having the slide anchor of the present invention, a metal rail is fixed to the outer surface of the frame material, and a metal slide anchor that is held by the rail and moves in the longitudinal direction is provided. When the plastic sash is attached to the PC board or the outer wall concrete of the building, the frame material of the plastic sash becomes free with respect to the slide anchor, and even if the plastic sash expands or contracts due to thermal expansion or contraction,
The PC board and outer wall concrete will not be damaged, the slide anchor will not be damaged, and it will not come off from the plastic sash.

Further, in the plastic sash having the slide anchor of the present invention, when a metal anchor member is rotatably and fixedly attached to the intermediate member for attaching the anchor member, before the concrete is placed. When the plastic sash is installed in the opening of the PC board or the like, by rotating the anchor member, the anchor member does not get in the way.

Further, the plastic sash of the present invention is
When the fixed anchor is fixed to the outer side surface of the frame material of the frame material of the plastic sash substantially at the center in the longitudinal direction, the expansion and contraction amount of the plastic sash with respect to the corner portion side of the plastic sash is reduced by half.
