Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sash made of a synthetic resin in which a reinforcing material is inserted in order to enhance heat insulation and dew resistance as a cold district specification and to supplement the lack of strength and rigidity.

[0002]

[Prior Art]

 For example, sashes used in cold regions such as Hokkaido and the Tohoku region are required to have high heat insulation so as not to let indoor heating escape to the outside especially in winter, and it is preferable that the sash be affected by the temperature difference between the inside and outside. A structure that can prevent dew condensation is required.

In recent years, in order to meet these demands, the material forming the window frame and the shoji frame of the sash is made of synthetic resin such as hard vinyl chloride from general aluminum alloy, and further, glass is used as a multi-layer. It is offered in glass.

Synthetic resins have a smaller elastic coefficient and are more easily deformed than aluminum alloys. Therefore, for frame materials that require rigidity and strength, aluminum or steel is used in the hollow space of the frame material. The reinforcement material has been inserted. For example, in the example of the sash shown in FIG. 8 in which the shoji 31 which can be opened and closed is attached to the window frame 30, the steel reinforcing material 32 is provided in the frame of the shoji 31 that is frequently opened and closed. Has been inserted.

[0005]

[Problems to be solved by the device]

 The shoji frame or window frame made of the synthetic resin sash is usually manufactured as a single material having a hollow structure by extrusion molding, and is assembled into a frame body. At this time, the corners (corner parts) are connected by cutting both ends of each single material at 45 °, applying a heating plate to the cut surface to heat, and then crimping and joining.

Therefore, looking at an example of inserting a conventional reinforcing material, as shown in FIG. 8, a reinforcing material whose end portions are cut vertically is used so as not to hinder the thermal welding of the corner portion of the frame material. In addition, each corner portion A of the shoji 31 was not reinforced with the reinforced region extending up to the vicinity of the inner edge. Therefore, as shown in Fig. 9, when the residual stress stored inside the frame material during extrusion molding is affected by solar heat or released over time, the difference in strain between the inside and outside of the room causes However, there was a case where the phenomenon of deforming to the outside of the room occurred. Even with a shoji frame made of a straight extruded material that releases residual stress, the thermal warpage that occurs when there is a temperature difference between the inside and outside of the frame causes creep stress when the window is closed. When the window was opened, the phenomenon that the frame was warped was observed.

The deformation due to the release of the residual stress remains as a permanent strain even if the heat is removed, and therefore the appearance and the airtightness and watertightness with the window frame 30 are deteriorated. Was causing problems. The deformation due to the residual stress is a remarkable phenomenon on the shoji side where the periphery is not constrained rather than the window frame.

Therefore, a main object of the present invention is to provide a synthetic resin sash capable of preventing deformation of a frame material due to release of residual stress and maintaining stable performance for a long time.

[0009]

[Means for Solving the Problems]

 The above problem is that the hollow structural members made of synthetic resin are obliquely cut at both end faces, and the end faces of these members are assembled by butt-welding and joining by heat welding, and a reinforcing material is inserted into each member. In a sash made of synthetic resin composed of a frame, the shape of the end of the reinforcement is matched to the shape of the joint surface of the member to be inserted, and this reinforcement is welded to join the members together. The problem can be solved by inserting with the allowances left evenly and substantially eliminating the unreinforced portion at the joint between the members.

[0010]

[Action]

 In the present invention, since the end shape of the reinforcing material inserted inside the frame material is almost the contact surface shape of the frame material, all the joint parts are firmly reinforced, so that residual stress is released. It is possible to prevent deformation of the frame material and maintain stable performance for a long period of time.

【Example】

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 is a vertical cross-sectional view of the outside window, and FIG. 2 is a cross-sectional view thereof. A sliding door 2 made of synthetic resin such as hard vinyl chloride resin material is attached to a window frame 1 manufactured by extrusion molding using synthetic resin such as hard vinyl chloride resin material. ing. The shoji 2 is rotatably supported by a hinge 5, and the upper frame 2A is provided with a tilt stop 3 connected to the upper window frame 1A. The hollow frame members 1A to 1D forming the window frame 1 are manufactured by extrusion molding, respectively, and then the frame members 1A to 1D are joined by heat welding to form a frame body. As shown in FIG. 7, the window frame 1 in the present embodiment is configured as a window for fitting and killing half the side of the vertical joint 1E disposed in the middle, and the window 2 is provided inside the vertical casing 1E. A reinforcing material 7 made of an aluminum alloy or a steel material is inserted to withstand the shock caused by opening and closing. In addition, the dead-fitting window has a double-glazing structure in which two pieces of glass G ₃ and G ₄ are fitted in order to ensure high heat insulation, and at the same time, in order to ensure air / water tightness, Tight materials 31, 31 having a plurality of contact pieces are used. Reference numeral 30 is a ridge for supporting the glasses G ₃ and G ₄ .

On the other hand, similarly, the shoji screen 2 is also configured as a double-glazing structure in which the glass G ₁ and G ₂ are fitted by the ridge 20 in order to ensure high heat insulation performance, and the glass G ₁ and G _{2 are also included.} High air / water tightness is secured around the periphery of the tight material by the tight materials 23, 23 having a plurality of contact pieces. Further, tight materials 10, 21 ... Are disposed between the shoji screen 2 and the window frame 1 in order to seal the gap and ensure air-tightness.

Each of the frames 2A to 2D of the shoji 2 has a groove-shaped reinforcing member 4A to 4D made of a rigid member such as aluminum alloy or steel along a hollow chamber P ₁ communicating with the four circumferential directions. Has been inserted. For example, as shown in the enlarged vertical cross-sectional view of the main portion (corner portion) of FIG. 3, the joints of the frames 2A to 2D of the shoji screen 2 have the ends of the lower frame 2B and the vertical frame 2C at 45 °, respectively. Cut into pieces and joined by heat welding. As shown in FIG. 4, the reinforcing members 4B and 4C according to the present invention have the ends of the reinforcing members 4B and 4C, etc. cut at 45 ° similarly to the joint surface S of the frame, and It is inserted with the welding margin x left evenly from the joint surface S. Therefore, the joints of the stiles 2B and 2C are reinforced by leaving a width of 2x for the welding margin, so that deformation due to release of residual stress is prevented. The size of the welding margin x is about 2 to 20 mm, preferably about 5 to 10 mm. The shape of the reinforcing member 4 is not limited at all, and may be an appropriate shape such as a U-shaped cross section shown in FIG. 5 or a closed cross section shown in FIG.
