Door frame reinforcement structure {REINFORCEMENT STRUCTURE FOR DOOR FRAME}

The present invention relates to a door frame reinforcement structure, and more particularly, to a frame frame reinforcement structure for preventing deformation by enabling a synthetic resin frame of various specifications without using a new mold and reinforcing structurally fragile synthetic resin frame. .

In general, the building wall is made to the entrance and the door frame is installed along the inner circumference of the door and the door door is installed to open and close.

The door is manufactured by fixing the plywood inside the frame of each of the top, bottom, left and right, and then fixing the frame and the plywood by using separate steel, wood, or adhesive to each corner of the frame and plywood.

When the manufactured door is installed, it is transported to the place to be installed and installed. Conventional doors are mainly transported in a state of assembly complete using heavy plywood and wood. The heavy weight made transportation and installation difficult and took much time to manufacture the doors.

Figure 1 shows the overall structure of the door 10 using a synthetic resin frame. Figure 2 shows the assembled state of the conventional synthetic resin door frame.

Looking at the conventional synthetic resin door frame structure with reference to Figure 2, the horizontal frame 11 and the vertical frame 12 is configured to constitute the entire frame of the door 10 and the horizontal frame 11 and vertical frame 12 The inside of the plywood 13 is coupled to the door 10 is configured.

The horizontal frame 11 and the vertical frame 12 are coupled through a separate coupling pin 14. In the horizontal frame 11 and the vertical frame 12, coupling holes 15 for mounting the coupling pins 14 are formed, respectively, and the coupling pins 14 are coupled thereto.

The upper portion of the plywood 13 is mounted on the bottom surface of the horizontal frame 11 and the side portion is mounted along the longitudinal direction of the inner surface of the vertical frame 12.

The material of the vertical frame 12, which forms a vertical column at the door, is injection molded and made of a synthetic resin material, and the hollow space 17 is formed to reduce the weight, so that the strength is weak. Insert into (17) to increase the strength.

Although not shown in FIGS. 1 and 2, protrusions are formed at the ends of the horizontal frame 11, and coupling grooves are formed on the inner surface of the vertical frame 12 so that the protrusions can be fitted to the horizontal frame 11 through the protrusions. There is also an example of combining the vertical frame (12).

As such, the conventional synthetic resin frame structure used for the door is manufactured in various structures according to the type of the door including the representative example shown in FIG. 2, and the frame and frame combination, and the combination of plywood and frame also have various types of structure Is being applied.

Various materials are selected for the frame used to make the door. Wood, synthetic resins, and metals are typical.

Wood is a natural material, which has the advantages of eco-friendliness, excellent processability and texture, and light weight and ease of handling.

Metal materials are superior to wood in terms of durability and strength, but are heavier, corrosive and less workable than wood.

Synthetic resins have corrosion resistance, good durability, and the desired strength can be obtained, but there is a limit to weight loss because the amount of material should be added or the implants should be filled in the space, and a separate surface treatment or finishing material may be attached to obtain excellent texture. Go through the process.

In this way, the material of the frame used in the door can be produced by selecting several materials, and the functional matters are mainly influenced by the selected material itself.

The door frame using the conventional synthetic resin as a material is manufactured similar to the shape of the frame as shown in FIG. 2 and may be molded by emptying the interior into a space to reduce the weight, but the weight should be maintained for sufficient strength and durability. There is a limit in weight reduction.

Looking at the problems in the fabrication and application of the conventional door frame made of a synthetic resin as follows.

First, a mold according to the frame specification is required. That is, since the mold is manufactured by forming a mold corresponding to the shape of the frame to be manufactured and then pouring the synthetic resin into the mold, a mold for molding the mold is necessary according to the specifications of the frame. In order to manufacture frames of various sizes, molds and facilities for forming frames are increased. Therefore, there is a problem that requires a large-scale facility investment.

Second, the amount of material used increases to structurally maintain the shape of the frame. In other words, since the entire frame is molded through a mold, it is completed by filling the inside of the frame with synthetic resin to maintain the strength and shape of the frame, or manufactured by maintaining an appropriate thickness. it's difficult.

Third, there is a limit in lightening the weight of the frame because the strength is maintained by the appropriate amount of synthetic resin material. Therefore, there is a problem in that the handling is difficult in the initial production and post-production transport and construction of the door.

Fourth, in order to reinforce the weak strength of the hollow hollow plastic frame, the bending and deformation of the frame cannot be controlled by the flow and deformation of the reinforcing material placed in the hollow of the synthetic resin frame and the frame strength cannot be kept constant. there was. Wood is deformed by shrinkage expansion and metal materials are advantageous for maintaining high strength, but are disadvantageous for weight reduction and corrosive.

The present invention was created to solve such a conventional problem, it is possible to simply produce a frame of various specifications through a common facility without using a new mold for changing the frame specifications and dimensions in manufacturing a synthetic resin frame used for the production of doors The purpose is to make it.

Another object of the present invention is to reduce the amount of synthetic resin material used in the production of synthetic resin frames used for the production of doors.

Still another object of the present invention is to make it easy to manufacture a synthetic resin frame and to reinforce weak strength.

Still another object of the present invention is to provide a synthetic resin frame which can be used as a general building material including a frame for doors by freely determining the thickness and width of the synthetic resin frame.

The door frame structure according to the present invention is configured as shown in Figs.

The main part comprises a panel 31 having a length, a thickness, and a width, a sheet 32 attached to the panel so as to form a surface layer of the panel 31 by enclosing one side portion including both edges of the panel 31, A bending groove 35 formed by bending the panel 31 to which the sheet 32 is attached and being bent around the bending groove 33 and its bending groove 33 which are dug along the longitudinal surface of one side of the panel 31. ); In order to reinforce the strength of the panel 31, the metal reinforcing bar 37, the metal reinforcing bar 37, and the panel 31 which are in close contact with the inner wall of the panel 31 to reduce the longitudinal deformation of the panel 31. It is composed of a resin adhesive layer 38 is filled in the gap between the inner wall of the metal reinforcing bar 37 to adhere and support the inner wall of the panel 31.

In addition, the prosthetic member 34 is selectively filled along the inner empty space of the panel 31 bent around the bending groove 33 of the bending part 35.

In addition, the panel 31 is a synthetic resin material, the inner and outer surfaces of the plate-like flat plate is formed by extrusion molding, forming a bending groove 33 on one side to bend the panel 31 around the groove 33 Thereby forming the bent part 35.

In addition, the sheet 32 attached to one side of the panel 31 is attached to the surface of the panel 31 using any one sheet selected from an aluminum sheet and a synthetic resin vinyl sheet. When the sheet 32 attached to the panel 31 is made of a thin aluminum sheet, the sheet can be prevented from catching fire. In the case of a synthetic resin vinyl sheet, a pattern having a desired surface texture can be selected by varying the pattern and texture. Configure 30.

In addition, the prosthetic member 34 inserted into the empty space 39 of the metal reinforcing bar 37 seated on the inner wall of the panel 31 may be any one selected from wood, metal, synthetic resin, or one or more materials. It is configured by being inserted into the reinforcement stand 37.

In addition, the metal reinforcing bar 37 is formed with an adhesive guide groove recessed in the inner direction to fill the resin adhesive layer 38.

Here, although the adhesive guide grooves 37a, 37b, 37c, 37d formed on the metal reinforcement 37 are shown in four places in the drawing, they do not necessarily need to be formed in four places.

At least one or more symmetrically formed on the metal reinforcement 37 is configured to increase the adhesive force by the resin adhesive layer 38.

When the adhesive guide grooves 37a, 37b, 37c, and 37d are symmetrically formed at positions facing each other, the thickness of the resin adhesive layer 38 can be maintained in a balanced manner to prevent adhesion failure due to variation in the thickness of the adhesive layer. It is advantageous.

In addition, the resin filling the panel 31 and the metal reinforcing bar 37 to form the resin adhesive layer 38 is preferably formed of an adhesive layer using a polyurethane resin excellent in ductility and adhesion.

For reference, the shape of the groove 33 of the bent portion 35 formed along the inner surface length direction of the panel 31 may be configured as a V-shaped groove, as shown in FIG. As shown in b), the inlet may be formed into a shape which is dug into a W-shaped groove which is bilaterally symmetrically extended.

In the manufacturing of the door frame 30 according to the embodiment of the present invention configured as described above, the plate-shaped panel 31 having a length, a thickness, and a width is molded into a length corresponding to the entire length of the frame 30.

The panel 31 is preferably molded into a flat plate inside and outside in consideration of surface texture and installation of the prosthetic materials 34. Herein, the length of the frame 30 is the total length of the frame 30 to be determined and obtained in advance.

When the molding of the panel 31 is completed, one surface of the panel 31 is wrapped with the sheet 32 including both edges of the molded panel 31 to wrap the surface of the panel 31.

By wrapping the surface of the panel 31, one side of the surface of the panel 31 forms a sheet layer attached to the sheet 32, and selects an inner surface other than the sheet layer portion to bend and fold the panel 31. A bendable groove 33 which can be folded and the panel 31 is folded about the bend groove 33.

When the panel 31 is folded, a hollow space 39a is formed, and the metal reinforcing bar 37 is inserted into the empty space 39a.

The metal reinforcing bar 37 inserted along the empty space 39a of the panel 31 forms a resin adhesive layer 38 by injecting a resin and thereby rests in the empty space 39a of the panel 31. It is adhesively fixed to the inner wall of 31.

In addition, the empty space 39 of the metal reinforcement 37 is formed for weight reduction, but the space 39 is filled with a separate prosthetic member 34 such as a light weight wood chip or a metal non-metal chip to further strengthen the strength. It can be produced in a structure to be.

Here, the resin adhesive layer 38 fills the gap between the outer wall of the metal reinforcement table 37 and the inner wall of the panel 31 and bonds the metal reinforcement table 37 to prevent close contact and flow.

The resin filling the panel 31 and the metal reinforcing bar 37 to form the resin adhesive layer 38 is preferably a polyurethane resin having excellent ductility and adhesion. The polyurethane resin absorbs the flow and deformation of the metal reinforcing bar 37 by its own ductility to prevent distortion or deformation of the entire frame.

The metal reinforcing bar 37 is bonded to the inner wall of the panel 31 in a planar state, and the thickness of the adhesive layer is determined by the thickness of the gap between the inner wall of the panel 31 and the outer wall of the metal reinforcing bar 37.

The metal reinforcement 37 extends to a position close to the inner wall of the panel 31 as a reinforcing material for compensating the strength of the panel 31. Therefore, the gap between the outer wall of the metal reinforcement 37 and the inner wall of the panel 31 is narrow, which does not form a sufficient thickness of the adhesive layer is difficult to maintain a stable adhesive strength.

The metal reinforcing bar 37 according to the present invention creates a space to fill the resin adhesive layer 38 and thereby increases the area of the adhesive layer, thereby recessing the adhesive guide grooves 37a and 37b inward to secure sufficient adhesive strength. (37c) (37d) are symmetrically formed in each direction of the metal reinforcing bar 37 to increase the adhesive force by the resin adhesive layer 38.

Through this, the metal reinforcing bar 37 reinforces the inner wall empty space 39a of the panel 31 without falling off and falling off and moving out of the inner wall of the panel 31.

Such a door frame 30 according to the present invention can be manufactured while freely adjusting the frame to obtain the dimensions, lengths and specifications without a separate mold.

In other words, by adjusting only the dimensions of the panel 31 to be initially formed in consideration of the specifications of the frame 30 to be manufactured, the bending groove 33 and the lapping of the sheet 32, and the panel 31 Through the bending and insertion process of the metal reinforcing bar 37, the frame 30 of various standards simply required is repeatedly manufactured.

The sheet 32 may be simply adhered to the surface of the panel 31 by applying an adhesive to the surface of the panel 31 or the surface of the sheet 32.

When the aluminum sheet 32 on the thin plate is wrapped on the surface of the panel 31, a flameproof treatment that is not easily burned is possible, and the adhesion to the surface of the panel is improved, thereby increasing the degree of completion of the sheet 32 stacking. Synthetic resin vinyl sheet 32 has a weak disadvantage in heat, but because the surface texture can be expressed in various ways through the printing of various patterns and various colors, suitable materials are selected and used as sheet paper.

The shape of the bending groove 33 formed on one surface of the panel 31 is formed by the V-shaped groove 33 or the W-shaped groove 33, as shown in Fig. 4A (b). The V-shaped bent groove 33 is advantageous to obtain a straightness when bending and bending compared to other shapes, and bends well when bent, and the W-shaped groove has a gradient surface formed at the inlet to form a V-shaped groove (33). Bends better than).

Thus, the bending grooves 33 formed in the panel 31 can be produced by adjusting the thickness of the frame 30 by adjusting the interval between the bending grooves 33 by forming a long continuous continuous interval along the longitudinal direction. .

6 and 7 illustrate an example of manufacturing the frame 30 according to another embodiment of the present invention, wherein one side of the panel 31 is not blocked and the frame 30 is opened by the opening 40. As a structure, the internal space which forms the opening part 40 is sealed by filling the PVC resin 41. As shown in FIG.

Such a structure is formed of two bent grooves 33 formed in the panel 31 to form one portion as an open portion 40 and plywood forming the door 20 outside the open portion 40 ( 21) is a suitable structure for bonding.

In addition, the metal reinforcing bar 37 is in close contact with the panel 31 by the synthetic resin layer 38, and the opening 40 may be filled with the adhesive layer, thereby adhering the metal reinforcing bar 37 to the panel 31 in a solid state. .

The door frame reinforcement structure according to the present invention does not add a separate injection process other than the injection molding of the plate-shaped panel 31. Additional processes include attaching the sheet 32 to the surface of the panel 31, forming the bending grooves 33 on the surface of the panel 31, bending the panel 31 to bend, and metal reinforcing materials ( 37) is inserted into the metal reinforcing material (37) to fill or install the prosthetic material (34). Machining the molded panel 31 itself or attaching new attachments to the panel 31 is central.

These processes are commonly included in the comparison of frame making. The operation of forming the bending grooves 33 in the panel 31 and bending the panel 31 again in the axis is different. In addition, the process of inserting the metal reinforcing material 37 into the empty space 39a of the panel 31 and filling the urethane resin to form the resin adhesive layer 38 to adhere the metal reinforcing material 37 is different.

This does not complicate the production or increase the process more than necessary compared to a typical frame making process.

That is, in the manufacture of the door frame, the present invention folds the panel 31 and inserts the metal reinforcement table 37 into the empty space 39a of the panel 31. It is produced by injection or by more complex cutting and molding.

In the door frame 30 according to the present invention, after forming the flat panel 31, the panel 31 is cut by the length corresponding to the length of the frame 30 to be manufactured to form the bending groove 33 and the bending groove. By folding around 33, the door frame 30 having a desired size and size can be manufactured without using various molds. The metal reinforcing bar 37 is inserted into the empty space 39a of the panel 31 and filled with resin to form a resin adhesive layer 38 to simply manufacture the reinforced frame 30.

In addition, the surface of the panel 31 is wrapped with an aluminum sheet 32, which is a flame retardant material that is not easily ignited, to enable flame retardant treatment for the door frame that is vulnerable to flame, and according to the material of the sheet 32 used Various textures can be realized. For example, by attaching a sheet of synthetic vinyl material 32, a surface treatment having a desired color, shape, and texture is possible.

8 shows an example of manufacturing the door 20 using the frame 30 manufactured according to the present invention.

As described above, in the present invention, the frame structure used for manufacturing the door 20 is manufactured in the synthetic resin frame 30, and the bending groove 33 is formed in the flat panel 31 without using a new mold for changing the frame size and dimensions. Forming a bent around this and reinforcing the weak strength through the metal reinforcement (37) to finish the production of the frame, there is an advantage that can be easily manufactured through a common facility without the use of a new mold frame of various specifications.

In addition, the production of the synthetic resin frame 30 used for the production of the door 20 has the advantage that can be economically produced by reducing the amount of material used as much as possible. That is, in the state where the thickness of the panel 31 is formed as thin as possible, the metal reinforcing rod 37 is inserted into the space formed by folding the bending grooves 33 on the shaft in accordance with the overall strength and the use of the frame 30, thereby making the frame of high strength economical. There is an advantage that can be produced.

In addition, there is an advantage that can be improved in handling and operability according to the weight reduction by reducing the use of materials used in the production of the frame 30 in the production and construction and transportation of the door 20.

In addition, by freely determining the thickness and width of the synthetic resin frame 30 to be produced in a variety of shapes without a new mold, there is an advantage that can be used for a variety of uses, such as general building equipment including the frame 30 for the door.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
