Description

Framework for window or door frame {WINDOWS AND DOOR'S FRAME STRUCTURE}

The present invention relates to a frame structure for a door frame configured to utilize larch and larva as a structural material for building, in particular, a door frame or window frame.

Larch and larva occupy almost all of the wood produced in Korea, have high strength, and have a beautiful appearance, making them widely used as structural materials and interior materials for general construction, but have large cracks and warpage due to dry shrinkage and nailing work. There is a problem that occurs when the crack.

Due to these problems, even though the price is only about 30% of the import price Nawang, and the supply volume is sufficient, the frame structure such as window frames and door frames that require unmodification after installation cannot use these larch or ground transportation at all. Relatively expensive, there was a limit to use Nawang that can not save the aesthetics of the pattern.

The present invention is devised for the purpose of utilizing the larch or the meat loquat, which could not be used as a conventional door frame or window frame structure as a door frame or window frame structure material, and presenting a framework structure with high durability.

To this end, the present invention proposes a new frame structure to suppress deformation and splitting, which is a characteristic of cut and larch, and overcomes the limitations of assemblability, which is a disadvantage of these woods, using various types of reinforcement.

Hereinafter, the configuration and operation of the present invention in detail.

Figure 1 shows the manufacturing process of the frame structure for the window frame or door frame according to the present invention, the present invention is a standard wood production step of re-cutting the cut pine or larch into the standard frame (1) for the window frame or door frame; A primary processing wood manufacturing step of forming a groove (2a) or jaw (2b) required for the construction of a window frame or a door frame on the surface of the standard wood; And a secondary processing wood manufacturing step of forming a reinforcing material insertion groove 4; and a structural material forming step of inserting a reinforcing material 5 of an iron sheet into the reinforcing material insertion groove and attaching it integrally with the processed wood; and of the reinforcing material constituting the structural material. A frame structure for a window frame or a door frame made by joining both ends to form a grid.

In the standard wood production step (a) is a step of formulating the standard wood for the window frame or door frame after drying the wood collected in the forest sufficiently can be used as it is commercially produced standard wood.

The first step of manufacturing wood (b) is a process of cleanly finishing the surface of the standard wood and forming the shape required for window frame or door frame manufacturing. In the case of the door frame, a threshold (2b) is formed at the part where the door is mounted, In the case of installing the rails or forming grooves (2a) to hang the upper end of the window, and the structure of the joining jaw is formed at the end of each processing wood, each processing wood is assembled even in the primary processing wood production step It is manufactured in such a state that it can be assembled as a grid-shaped door frame or window frame.

The secondary work wood manufacturing step (c) is a window frame or door frame that forms crack absorption grooves (3) in the pre-assembly wood before the assembly to prevent cracking and shrinkage during the drying process. It is a step of forming a crack absorption groove 3 and a reinforcing member insertion groove 4 of a predetermined interval on the rear surface of the primary processing wood for the purpose of preventing deformation.

The crack absorbing grooves are formed in the longitudinal direction on the back surface of the processed wood, and formed in a depth of 1 / 2-1 / 3 with respect to the thickness of the processed wood, and the gaps between the grooves are equal to or slightly larger than the thickness of the processed wood. By doing so, the stress acting length due to the dry shrinkage can be maintained in the same range over the entire cross section, and the crack due to the shrinkage can be effectively prevented.

Structural material forming step (d) is to reinforce the processed wood, to suppress warping or deformation, and to prevent cracking during nailing, which is the biggest weakness of larch and larch. ) Is a process of attaching the fixed wood and attaching it integrally with the processed wood.

By assembling the structural materials produced by the above processes respectively, it becomes a lattice-shaped frame structure, and each corner joint is welded by the protruding reinforcement material by the internal structure of the core by the reinforcement material and the double structure which is the wooden structure exposed to the outside. The framework structure is completed.

The frame structure is installed in the window according to the general construction method of the building and finally completed as a window by assembling a door or window.

In the reinforcement (5) is to restrain the deformation of the structural member while acting as a deep part of the structural member can be configured in various forms.

The reinforcement 51 according to FIGS. 3A and 3B has a structure in which both ends of the iron plate 51a are bent to form protrusions 51b at both ends thereof, so that the protrusions 51b are inserted into the reinforcement insertion groove 4. The protruding portion suppresses warping or cracking due to the contraction of the wood structure and reinforces the weakening of durability due to the formation of the crack absorption groove.

The reinforcement is formed to be somewhat longer than the wood structure so that the end is slightly protruded from both ends of the processed wood to be assembled by the method of welding each other by finishing the protrusions when assembling the processed wood into the frame structure.

The reinforcement may be configured in various forms in addition to the forms described above.

4A to 4B show a structure in which the reinforcement 52 is formed of a straight plate, and the wedges 52a are formed at both ends of the reinforcement, and the structural members are integrally formed by joining two pieces of wood together. It is useful when manufacturing a frame structure such as a door frame or a window frame.The two pieces of wood are firmly bonded and mutually integrated by the action of the wedge, and if necessary, the adhesive is applied to the bonding part before the bonding to make it more firm. can do.

5A and 5C show the reinforcing member 53 formed in the 'T' shape by forming the protrusion 53b at the center of the iron plate 53a, and having a structure in which a separate wedge 53c is formed on the protrusion 53b. Include.

The reinforcement 53 according to the above shape has a high reinforcement and torsion-prevention effect by being used in a lumber structural material having a relatively large thickness compared to the width, and a structure formed with a wedge in the protrusion has an effect of enhancing adhesion between wood and the reinforcement. Done.

6a and 6b show the structure of the reinforcing material 54 in the '+' form by forming the protrusions 54b at the central portions on both sides of the iron plate 54a. Allows the fabrication of structural materials.

7a and 7b is a reinforcement member 55 in the form of a ladder structure by arranging two straight reinforcement member 55a in parallel and then attaching a plate (55b) at a predetermined interval and the window frame structure for the double production As it is used in a wide window frame structure, it has an effective reinforcement and torsion prevention effect.

The reinforcement 56 shown in Figs. 8A and 8B is used for joining the joints between the inter-member and the window frame when the inter-member is added in the middle of the window frame to increase the durability of the wide window frame, or by using the joint part of the horizontal member and the vertical member. It is used for the purpose of enabling a robust assembly without having to have a structure in which protrusions 56b are formed at right angles above and below both surface ends of the iron plate 56a.

The above configuration has a function of allowing the horizontal member to be joined to the upper protrusion and the vertical member to be joined to the lower protrusion to join two mutually orthogonal members without using nails.

In the figure, reference numeral 7 denotes a frame structure, 8 denotes a window, and 10 denotes a rail.

The present invention is inexpensive and abundantly supplied, and despite having a beautiful appearance, it is not possible to use in the production of sophisticated interior structures such as window frame or door frame structure due to deformation due to cracking and torsion, the window frame or door frame structure As it can be used as a substitute for Nawang, a foreign imported mountain, it is economical and abundantly produced in Korea.

In addition, the wood structure having a beautiful appearance and the strong steel structure can be combined with each other to form a strong and strong skeleton as a whole, excluding the joining of the joints by nails and joining by welding between the reinforcement materials at the joints. Has the effect of preventing the source of cracking.
