Description

Cement material window frame where natural veneer door part is removable {DOOR FRAME MADE OF CEMENT CAPABLE OF ATTICHING DECORATION PARTS}

The present invention is to form a bonding structure in the outer portion of the cement material window frame composed of a mixture of kneading and mixing various performance modifiers based on the cement, extruded in a die through an extruder and then curing in a steam curing tank of high temperature and high pressure The present invention relates to a window frame configured to be assembled and assembled with various members such as synthetic resin, artificial wood, natural wood, and metal pattern material.

The most natural way to build a house is to use natural materials such as loess and wood. These natural materials are durable in their own way, but they are difficult to fit in modern tastes, and various artificial materials are used not only in terms of durability but also in terms of raw materials, limited processability, and limited productivity. The most outstanding of these artificial materials is the construction method of concrete materials using rebar and cement. When these materials are injected into the mold, they can obtain any desired structure, and they occupy most of modern architecture due to their relatively low production cost. However, as various shortcomings of concrete materials have been pointed out, various materials have been provided as substitutes, but they are not enough to replace the basic skeletal structure itself, and remain in use only for non-bearing structures or interior materials.

The present inventors manufacture a window frame having a plurality of hollow parts by mixing a synthetic or natural fiber yarn and a performance-enhancing agent of synthetic resin series using cement as a base material, and then passing a slurry of water-kneaded slurry through a die of a certain form through an extruder. Has come. Among the shortcomings of the cement window frame, the appearance is significantly lower than that of natural veneer. In 1999, patent application 136819, the width control is free as wood, and various types of door pattern material can be fastened to the left and right sides. It suggests a window frame and its manufacturing method. Here, the combination of the door pattern member was inserted into the hemispherical groove, and then a means of applying by applying an adhesive was adopted. In this case, if both adhesives are in close contact with each other, it is almost impossible to replace and repair the door pattern part if damage occurs. In addition, it is difficult to establish a solid structure with adhesive alone to be applied to various materials, there is a limit to the use.

In 1999, Patent No. 63390 uses a three-dimensional pattern forming apparatus that allows continuous molding of uneven patterns during extrusion of cement material. To get closer to nature.

In another proposal, Patent No. 1200 of 2000 provides a window frame using an adhesive using a sheet sheet lapping device for a synthetic sheet material. That is, by expressing a variety of sheet material printed with natural veneer on the surface itself of the window frame itself, it is possible to express the pattern more easily. Therefore, it is possible to secure the convenience and mass productivity by providing various window frames as long as the synthetic resin sheet is replaced.However, in the case of the lower frame or the externally exposed window frame, the wear is prevented by friction. It is easy to deteriorate due to external strong light, moisture, etc. is a disadvantage. Therefore, when the sheet is peeled off due to such deterioration or various causes, there is a disadvantage in that repair replacement is impossible like a general wooden door frame.

In addition to the above-mentioned methods, so-called MDF artificial wood, which is pulverized into finely pulverized trees or lumbers and then molded into a certain form using an adhesive, is widely used. MDF is a synthetic resin sheet adhered to the surface, and the material itself is wood, and because it uses inexpensive mixed or waste wood, it is widely used because of its excellent price and productivity. However, the problem caused by the use of such MDF material is, firstly, that the adhesive does not maintain its function and is destroyed by moisture when exposed such as a toilet or an outer window. Secondly, in case of installing the window frame in the house, the frame is formed on the left, right, top, and heart by using veneer board, and then the window frame made of MDF material is fixed here. Therefore, if the window frame needs to be repaired and replaced due to various reasons, the window frame must be forcibly removed, and at this time, the frame made of veneer will be damaged. In other words, without a new installation of the whole bottle is not possible to replace the repair is more expensive than new installation. Third, the most fatal drawback is the lack of fire resistance. In other words, it is composed of wood and adhesive is provided as a powerful fuel at the moment of ignition is generated toxic gas to cause fatal asphyxiation. In addition, since the frame is made of wood, the structure of the window frame is easily separated and removed because there is no affinity with the existing cement material.

The present invention can exhibit durability without changing the basic structure even when exposed to moisture, heat, light, etc., and can be easily replaced and repaired even if a part of the pattern part is damaged. We want to provide a window frame that stays and is constructed so that the basic structure doesn't burn at all. Therefore, the internal structure is to be a stable cement and the outer exposed part to be the same as natural veneer to provide a window frame with both advantages.

In the present invention, the window frame is a mixture of various cement performance modifiers such as hardening accelerator, strength enhancer, and kneading accelerator after fine fiber yarns are kneaded and finely mixed in cement, and then mixed with an appropriate amount of water to extrude through a high pressure extruder. It is molding. The structure of the hollow portion 10 can be changed depending on the shape of the die during extrusion, and is not limited to any particular form. In other words, according to the structure, width, etc. of the window frame can be adjusted to the most economical and performance-free. After extrusion, curing is completed by curing for one or more days in a closed state in a steam curing tank maintained at a temperature of at least 100 to 120 ℃.
