Description

  The present invention relates to a maintenance method for reinforcing a resin sash.

As the resin sash, for example, a sash window and a shoji are assembled using a resin extruded profile.
Reinforcement is performed by injecting and filling urethane into the hollow portion of the extruded resin shape.

The method of injecting and filling urethane into the hollow part of the shape material is poor in adhesion between the resin used for the shape material (for example, PVC) and urethane, so the strength cannot be improved sufficiently, and the shape of the shape material cannot be improved due to an earthquake or the like. A gap was formed between the inner surface of the hollow portion and the urethane that had been filled and cured, and the profile was damaged.
Further, since urethane before curing has fluidity, when urethane is injected and filled into the hollow portion of the shape member, the urethane sometimes flows out to other than the reinforcing portion.
For this reason, the strength of the reinforcing portion could not be sufficiently improved even if urethane was filled in the hollow portion of the shape member.

  Therefore, an object of the present invention is to provide a method for maintaining a resin sash that can solve the above-described problems.

  The first invention is to fill and fill the hollow portion of the shape forming the resin sash with a filling material, fill the filling hole into the fixing hole formed in the shape material, and connect the shape and the filling material. A method for maintaining a resin sash, comprising reinforcing a shape member.

  In the second invention, a filling material is injected and filled into a hollow portion of a profile forming a resin sash, and then a fixing hole and a fixing recess are continuously formed in the profile and the filling, and this fixing A resin sash maintenance method comprising reinforcing a shape member by filling a melted resin over a hole and a fixing recess and connecting the shape member and a filler.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a filler is packed at both ends in the longitudinal direction of the reinforcing portion of the hollow portion of the profile to form a weir for preventing the flow of the filler, and thereafter the hollow portion This is a maintenance method for a resin sash that is filled with a filling material.

According to the first aspect, the filling material injected and filled into the hollow portion of the shape material fills the fixing hole of the shape material, thereby connecting the shape material and the filling material.
Since it is like this, even if the adhesiveness of resin of a shape material and a filling material is bad, a shape material and a filling material are connected firmly and the intensity | strength of the reinforcement part of a shape material can be made strong.

According to the second aspect of the present invention, the shape material and the filling material are connected by filling the resin into the fixing concave portion of the filling material injected into the hollow portion of the shape material and the fixing hole of the shape material.
Since it is like this, even if the adhesiveness of resin of a shape material and a filling material is bad, a shape material and a filling material are connected firmly and the intensity | strength of the reinforcement part of a shape material can be made strong.

  According to the third aspect of the invention, the filling material injected and filled into the hollow portion of the shape member does not flow except for the reinforcing portion.

A first embodiment of a reinforcing method by filling and filling a filler will be described.
As shown in FIG. 1, the vertical profile 1 and the horizontal profile 2 are resin extruded profiles having the same cross-sectional shape having a hollow portion 30, and the end of the vertical profile 1 and the end of the horizontal profile 2. The parts are cut at 45 degrees, butted together and connected by welding or the like, and each hollow part 30 is continuous.
Filling holes 31 are formed near both ends in the longitudinal direction of the reinforcing (repairing) portions on the surfaces 9 of the vertical and horizontal shapes 1 and 2, and fixing holes 32 are formed between the two filling holes 31. A plurality are formed at intervals in the longitudinal direction.
The holes 31 and 32 open to the hollow portion 30.

A filling, for example, glass wool 33, is put into the hollow portion 30 from each of the filling holes 31, and the glass wool 33 is brought into contact with the inner surface 30a of the hollow portion without any gap to form a weir 34 that stops the flow of the filling.
A filler, for example, urethane 35 is injected and filled into the hollow portion 30 from each fixing hole 32, and the urethane 35 is put out from each fixing hole 32 to the surface 9 as shown in FIG. The shape materials 1 and 2 and the urethane 35 are fixed.

  For example, the urethane 35 is injected and filled into the hollow portion 30 from the lower fixing hole 32, and the injection and filling is stopped when the urethane 30 leaks from the upper fixing hole 32.

  The urethane 35 leaking from the fixing hole 32 to the surface 9 is scraped off after being cured to be substantially flush with the surfaces 9 of the shapes 1 and 2, and is painted to have the same appearance as the surfaces of the shapes 1 and 2.

  In this way, even if the adhesion between the resin of the shapes 1 and 2 and the urethane 35 (filler) is poor, the shapes 1, 2 and the urethane 35 are strong because of the urethane 35 filled in the fixing holes 32. The portion (reinforcement portion) where the urethane 35 is injected and filled is strong. Each filling hole 31 may be the same as the fixing hole 32 after filling. That is, the urethane 35 is filled.

  Further, the urethane 35 injected and filled into the hollow portion 30 does not flow except for the repair (reinforcement) portion by the weir 34 that stops the flow of the filling.

It is preferable to use a material that can be easily put through a small hole by compressing and deforming the above-described filling and that is restored to its original state in the hollow portion 30.
For example, the above-mentioned glass wool, balloon, cotton, sponge and the like are preferable.
The filling material is not limited to urethane, and epoxy resin may be used.

Next, a second embodiment of a reinforcing method by filling with a filler will be described.
As shown in FIG. 3, filling holes 31 are formed near both ends in the longitudinal direction of the portions 9 to be reinforced (repaired) on the surfaces 9 of the shapes 1 and 2, and fillings such as glass wool 33 are formed from the filling holes 31. In the same manner as described above, the dams 34 for stopping the flow of the filler are formed in the hollow portion 30.
A filling material such as urethane 35 is injected and filled into the hollow portion 30 using the filling hole 31. In addition, you may make the hole for injection filling separately.

After the urethane 35 injected and filled into the hollow portion 30 is cured, as shown in FIG. 4, a fixing hole 32 is continuously formed from the surface 9 of the shape members 1, 2 to the urethane 35, and the fixing recess 36 is formed in the urethane 35. Form.
The same resin as that of the shapes 1 and 2 is melted and poured from the fixing hole 32 to the fixing recess 36 and packed as shown in FIG. 5, and the shapes 1 and 2 and the urethane 35 are connected by the packed resin 37.
The surface of the packed resin 37 is scraped off to make it substantially flush with the surfaces of the shapes 1 and 2 to improve the appearance. The fixing recesses 36 may be formed in the urethane 35 by forming the fixing holes 32 in the filling holes 31 filled with the urethane 35 after the urethane 35 is cured.

The above filling injection may be performed at the repaired part of the damaged part so that the repaired part will not be damaged again by an earthquake or the like, or when the damaged part is narrow and the depth cannot be repaired as described above. May be repaired and reinforced by injecting and filling the damaged part.
Moreover, even if it is not damaged, it may be prevented from being damaged by an earthquake or the like by injecting it into a place where it is predicted that damage may occur due to an earthquake or the like based on past experience.
