Definitions
- the present invention relates to a synthetic resin profile product used as a window, and more specifically, the size of a welding line of a synthetic resin profile product for windows and doors manufactured by welding a synthetic resin profile is minimized, and a decorative sheet attached to the surface of the synthetic resin profile body after welding. It relates to a synthetic resin profile product for windows and doors that can be maintained firmly.
- the window is composed of a window frame installed in an opening of a building and a window frame coupled to it, and is divided into a casement, a sliding door, etc. according to the opening and closing method, and is classified into a wooden window, a synthetic resin window, and a metal window according to the material.
- the window frame and the window frame of the synthetic resin window are formed in a rectangular frame shape by the combination between the synthetic resin profiles P (see FIG. 1).
- the synthetic resin profile product 1 may be in a state where a decorative sheet S is attached to the surface of the synthetic resin profile body P, which is usually extruded from a PVC resin composition, and each synthetic resin profile body P After the ends are cut in a diagonal shape of approximately 45°, the ends are welded to each other to form a welded portion 20 to form a window frame and/or window frame in the form of a square frame (see FIGS. 1 and 2).
- the synthetic resin profile welding device for windows and doors secures the synthetic resin profiles, each of which is cut diagonally to the clamp.
- welding is performed between the synthetic resin profiles by pressing each other before the melted portions are hardened, and burs generated in the melted portion during the pressing process are subsequently removed using a separate device such as manual or finishing machine.
- the conventional profile product for windows and doors manufactured in this way removes the burrs (B) after welding, the burrs (B) generated at the time of heating and melting the synthetic resin profile with the heating plate are interfered with during welding between the synthetic resin profile bodies (P).
- the welding line (L) still having a large width and height even after removing the burr (B) with a separate chisel (T) or finishing machine ) Is exposed to the surface of the product, there is a problem that the aesthetic sense is greatly reduced. Because the welding line (L) has the color of the synthetic resin profile body (for example, white), the product appearance quality is greatly reduced due to the white welding line exposed between the decorative sheets.
- Patent Documents Korean Patent Registration No. 10-1364023 (Announcement date: 2014.02.18.)
- the present invention has been devised to solve the above-mentioned problems, in order to minimize the size of the welding line formed on the surface of the welding part in the process of welding the ends of the synthetic resin profile to each other, to make use of the beauty of the product appearance, and the decorative sheet is a synthetic resin profile. It is an object of the present invention to provide a synthetic resin profile product for windows and doors to effectively solve problems such as being lifted or peeled from the main body.
- a synthetic resin profile product for windows and doors comprising a synthetic resin profile welded through a weld, wherein the synthetic resin profile includes a body and a decorative sheet attached to the surface of the body,
- At least one end of the decorative sheet is configured to be inserted into the body.
- the synthetic resin profile product for windows and doors removes burrs in the process of melting the ends of the synthetic resin profiles with a heating plate, so that the occurrence of burrs is minimized when welding the ends of the synthetic resin profiles after the heating plate is removed, thereby decorating sheets in the welding process.
- the synthetic resin profile can be rolled into the body to minimize the size of the welding line protruding from the surface of the welding part to make the appearance beautiful and to effectively prevent the decorative sheet from being lifted or peeled from the synthetic resin profile body. It works.

- the surface of the heating plate 120 in contact with the cut surface of the synthetic resin profile 10 may be treated with Teflon coating.
- synthetic resin which is a material of the synthetic resin profile 10
- the blade 113 may be elastic by the spring 114. In this case, even if the tips of the blades 113 formed to face each other collide with each other, the blades 113 can absorb shock as they are elastically supported by the spring 114, thereby preventing the blades 113 from being damaged. Can.
- a stopper 115 protruding downward may be coupled to the bottom surface of the lower pressing piece 112.
- a gap between the blades 113 provided on the upper and lower pressurizing pieces 111 and 112 is coupled to the bottom of the heating plate 120 by a gap maintaining block 125 having a constant width in contact with the stopper 115. This can be kept constant (see FIG. 11).
