Abstract

The present invention relates to a window frame made of extruded cement material freely adjustable width and its molding apparatus.

Cement is used as the main material, and various performance modifiers, inorganic and organic fiber yarns are kneaded, and then extruded through a die of a certain form, and then the window frame cured in a high temperature and high pressure curing tank replaces wood and steel. Has been developed and used.

Such a cement window frame has a limitation in being employed in private houses or apartments having various widths because the width cannot be adjusted once molding is completed.

In the present invention, the main frame and the width of the auxiliary frame is formed in the extrusion molding of the window frame, so that the main frame and the auxiliary frame can be appropriately combined according to the work site, so that the window frame can be fitted with various shapes and widths. In particular, in the manufacture of the auxiliary frame, it is possible to manufacture a sub-frame having various widths with only one die having the width of the extrusion die, thereby providing a new manufacturing method that does not require a separate die manufacturing according to the width.

Description

Extruded window frame and molding apparatus for cement material with free width control {Window and door frame capable of changing width and its producing system}

The present invention relates to a cement material extruded window frame and a molding apparatus of which width is freely obtained by mixing various inorganic and organic reinforcing agents in cement and slurrying them, and curing them at a high temperature and high pressure after extrusion in a predetermined form.

A window frame is generally composed of wood, synthetic resin, or metal in a certain form, and is a structure in which a window or a door acts as a sliding door or a sliding support base. Unlike window frames of metal or synthetic resin materials, the cement improves tensile properties by mixing performance enhancers such as chemical-resistant materials and strength reinforcements with inorganic fiber yarns such as synthetic fibers, glass fibers, and rock wool. After extruding and curing in a curing tank that maintains high temperature and high pressure, an inorganic window frame having a cement-like structure is formed. Since the window frame has almost the same strength as the rock, it has almost no abrasion even if it is used as a sliding door structure for a long time, and there is almost no deformation or aging due to heat or chemicals. As it is kept intact, it is widely used especially when building large apartments.

However, after curing is completed in a certain shape, especially a certain width, secondary processing is almost impossible due to the characteristics of the material, so it is difficult to mass produce a window frame having various widths. In other words, due to the distinctive characteristics of the current architecture, the demand varies from narrow window frames to relatively wide window frames. Therefore, mass production of appropriate window frames requires a large number of dies for various dimensions. Various problems are being raised. As shown in FIG. 1, the window frame of a general inorganic material has an upper surface 100 forming a stage, and a door line 103 is attached to the left and right sides 101 and 102 for decoration, and a plurality of bonding coupling grooves are formed on the bottom surface thereof. 104) is formed to combine with the mortar. And the adjustment of the width is not at all possible at present, and only the desired one was obtained by deforming the die to a wider one in continuous extrusion. As a result, in order to mass-produce products with various widths, various dies must be prepared and produced according to the change of width, and there is no other alternative. Therefore, despite the superiority of the inorganic window frame, the demand class has only been applied to a large number of standardized or semi-community apartments, but has not adapted to the private demand for various changes.

In order to solve the above problem, the window frame, which has been recognized to be basically composed of only one single body, is divided into two parts and then made to be fitted together. Therefore, the mold was divided into a main frame and an auxiliary frame to be extruded, and the two molds were molded to form concave portions and convex portions on one side so that they could fit together. At the time of final bonding, a separate adhesive layer was formed in the middle to enable more firm bonding between them. In addition, only the dies for the production of juttles were prepared, and the auxiliary frame developed a manufacturing device that can be adjusted to adjust the side or top and bottom to enable the production of window frames of various widths and top and bottom patterns.
