Description

Door frame {A Member for Door-Frame}

This paper relates to door frame materials for use in installing door frames in buildings. Especially, wood boards and chipboards are joined together to form a composite and completely block the ingress of moisture. It relates to a door frame material which does not occur in shrinkage expansion, structural strength is increased, durability is improved, and can be produced at economical cost.

The installation of the door frame is carried out together with the exterior construction, and after the installation of the windows, the interior construction continues. As such, the door frame installed prior to the interior work is damaged during contact with various materials during the interior work, or is soiled with cement mortar or sand.

Therefore, these door frames must not only take protective measures to prevent damage and maintain cleanliness, but also follow-up work as a countermeasure against fouling and damage after interior work.

In addition, the door frame material is manufactured to a certain standard in the factory, but because the concrete wall is formed in the form of the door portion is formed in the field, the thickness of the wall cross section and the door frame member has a certain deviation. As such, the wall and the door frame member having different thicknesses need a structural part that needs to be flexibly adjusted to coincide with each other.

Accordingly, in the construction of the door frame in recent years, during exterior construction, only the basic frame that receives the load acting on the door frame is installed, and after completion of the interior construction, cover the outer surface of the basic frame with a separate synthetic resin cover plate. The prefabricated method of covering and finishing is being actively implemented.

Such a prefabricated door frame is concealed by a cover plate even if the mortar or the like is partially damaged on the basic frame during the interior construction, and the cover frame is flexibly adjusted to cover the contact area between the door frame and the wall, so that the exterior of the door frame is finished cleanly. Has an advantage.

On the other hand, since the door frame is a structural unit for fixing the door, the support load of the door and the impact load each time the door is opened and closed. Such door frames have been manufactured and used in various materials.

Concrete door frame has a large structural strength, heavy weight, difficult to handle during construction, and difficult to repair if broken during or after construction.

The door frame made of aluminum is easy to handle due to its moisture resistance, workability and light weight, but it is insulated and has a high price, so it tends to avoid its use.

Synthetic resin door frame has the advantage of being strong against moisture, but since it is molded into a hollow cross-section, it does not have the structural strength to support the working load on its own and the thickness of the door to fix the hinge screw of the door. have.

Door frame using urethane foam is excellent in insulation and easy to manufacture, but it has to be manufactured at a high density in order to support the working load.

The door frame made of wood is the most widely used to date due to advantages in workability and structural performance compared to the door frame materials described above.

However, wood is easily deformed by moisture, and the dense tissues that make up the wood maintain a constant cross-sectional shape as they are pushed or pulled. Local deformation of this cross-sectional area creates new stresses that the tissues interact with. As a result, material deformations occur that bend or distort as a whole.

Therefore, the wood is basically suitable for use as a conventional door frame material that maintains a quadrilateral cross section, but is not suitable for use as a basic frame, which is a main structural part of a prefabricated door frame that has been actively implemented in recent years.

That is, the door frame material for use as a basic frame of the prefabricated door frame should form a plurality of grooves for joining the cover plate to the top, bottom and length surfaces or to secure the fixing force to the wall, these grooves are made of lumber or laminate When formed in the overall warp or warpage deformation occurs badly, it was practically difficult to manufacture the door frame material that the cover plate is assembled using wood.

On the other hand, recently, as a wood processing product that compensates for the shortcomings of wood, chipboards have been developed that are hot-pressed plated by adding organic adhesives such as synthetic resin adhesives after cutting the wood into small pieces and drying them sufficiently. It is widely used.

This chip board has strong hygroscopicity, and when moisture penetrates, material separation phenomenon occurs and tissue breaks down, and it is used with an outer sheath to prevent moisture penetration, and its structural strength is somewhat inferior to that of lumber or plywood. Although it has low deformation, excellent ability to cope with shear force, and not only has the advantage of ensuring uniformity, but also has the advantage of significantly lower price than lumber or plywood.

Therefore, a chip board having such a property and a structural material having excellent structural strength as described above but easily deforming due to a change in cross section can be used as a door frame material by mixing two kinds of members. There will be.

Accordingly, this paper is designed to realize the door frame material that can be assembled as a cover plate even as wood, and the purpose of this paper is to join a lumber or plywood with a chipboard to form a composite and to completely block the penetration of moisture. In this way, it is possible to provide a door frame material that can be produced at economical cost by improving structural strength and durability without causing bending, warping deformation or material separation phenomenon of the material.

In order to achieve the above object, the door frame member of the present paper has a predetermined thickness and width, and the board and chipboard extending in the longitudinal direction are joined to form a composite, and cover the top, bottom and length surfaces of the composite. The basic feature of the technical composition is that it consists of a rectangular member formed by digging grooves for joining the plates or securing the fixing force to the wall, and a cover material attached to the outer surface of the rectangular member to surround the rectangular member so that it is not exposed to the outside air. It is done.

This proposal, which is constructed as described above, forms a rectangular member by joining a board with high structural strength and a chipboard with less deformation and ensuring uniformity, so that deformation does not occur even if grooves are formed on the outer surfaces thereof. Its structural performance remains the same.

In other words, according to the proposal, the chipboard bonded with the plate holds the stress of the wood structure to bend or twist according to the change of the cross section due to the various grooves formed for use as the prefabricated door frame material, and the structural strength is relatively high. The high timber faithfully plays the role of bearing the supporting load of the door fixing nail or the impact load generated when opening and closing the door.

In addition, this proposal consists of a wooden board and a chip board wrapped in a weak material that is fragile in moisture to cover the exposed to the outside air, so that the moisture penetration into the tissues and the joint surface of the wooden board and chip board is blocked at the source, No material separation or deformation due to the action of

Therefore, this proposal is to implement a door frame material that can be constructed of a prefabricated door frame using wood that exhibits superior performance in terms of workability and structure compared to other members, and by appropriately utilizing a chip board having low cost of raw materials It is possible to manufacture the door frame material, which enhances economic feasibility.

Hereinafter, the technical configuration of the present invention will be described in more detail with reference to the accompanying drawings in accordance with an embodiment of the present invention.

Figure 1 shows a representative embodiment for implementing the door frame material of the present invention.

In this embodiment, the wood board 11 and the chipboard 12 extending in the longitudinal direction with a predetermined thickness and width are joined to each other to form a composite, and cover the top, bottom and length surfaces of the composite. The rectangular member 10 formed by digging grooves 13 for joining the plates or securing the fixing force to the wall and the outer surface of the rectangular member 10 are attached so that the rectangular member 10 is not exposed to the outside air. Consists of a covering material 20 wrapping to form one door frame material.

Here, the rectangular member 10 has a wooden board 11 therebetween, and one side of the wooden board 11 is bonded to the chipboard 12a for a load having a thickness similar to the wooden board 11, the other side surface The reinforcing chipboard 12b having a relatively thin thickness is plate-bonded to form a composite.

As described above, the door frame member of the present embodiment in which chip boards having different thicknesses are bonded to each other on the lower surface of the wooden board to form a rectangular member bears the main load acting on the door frame together with the wooden board by a thick chip board bonded to one side of the wooden board. In addition, the thin chipboard attached to the other side of the wooden board may reinforce the strength of the member to some extent, but its main role is to increase the adhesive force of the coating material attached to the outer surface of the rectangular member.

On the other hand, the present invention is not limited to the cross-sectional shape as shown in Fig. 1, the width and thickness proportional to the design of the door frame is different, the shape, number and position of the grooves are also changed.

In other words, what is important in this paper is to implement a door frame member that can be assembled with a cover plate by attaching a wood board and a chip board to form a square member, and attaching a cover material to block the penetration of moisture on the outer surface of the square member. .

And, in the implementation of the present invention, the wood board 11 is selectively used any one of lumber wood or plywood. That is, the lumber timber has the advantage of excellent workability, plywood has the advantage that can be easily secured evenly economical and uniformity, which is used to select any one as needed.

In addition, the coating material 20 can be applied to any material as long as it is opaque and thin, but considering the economical and aesthetics of using a thin PVC film with perfect moisture blocking. desirable.

Hereinafter, the method of installing a prefabricated door frame using the door frame material by this invention is demonstrated.

Figure 2 shows an example of a prefabricated door frame installed using the present invention. Referring to Figure 2, in installing the door frame using the door frame material of the present application, the cement mortar 112 is applied to the end face of the preformed wall 111, and the chipboard 12a for the strength of the door frame material of the present invention is in contact with this. Position the surface to the wall 111 side to install the base frame of the door frame.
