Description

[0001] Reinforcement frame of door frame [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a frame reinforcement frame which can be fixed to a door frame without a drill piece (Self drill screw). More specifically, the frame reinforcement frame is rigidly coupled to the door frame by a double- And is coupled to the door frame by a press-fit projection formed on the bottom of the floor to prevent movement (slipping or falling).

Generally, a frame applied to a door frame (window frame) of a building is composed of a metal or a non-ferrous metal, and is excellent in durability. However, since it is vulnerable to moisture and moisture, it has a drawback in that it is corroded and deteriorates in heat insulation and manufacturing cost. A door frame formed of a synthetic resin material (ABS) is widely used.

The above synthetic resin door frame is free from corrosion, has various shapes and structures, and is low in cost. On the other hand, its strength is lower than that of metal or non-ferrous metal materials. There is a problem that a gap is generated between the walls or a noise is generated when the door is opened or closed.

Therefore, it is possible to improve the strength of the synthetic resin door frame and the hinging force of the hinged door installed on the synthetic resin door frame by installing a metal reinforcement material or a metal reinforcement material and a reinforcement neck in the concave groove formed in the longitudinal direction of the synthetic resin door frame, It is prevented from being deformed due to the generated deflection.

Fig. 1 is a partial cross-sectional view of a conventional door frame (or window frame), in which a plurality of concave grooves 3 and 4 are formed in the longitudinal direction of the door frame 2 on the outer side of the door frame 2 fixed to the wall body 1, And the reinforcement frame 5 which is bent at right angles at a plurality of times is joined to the one side groove 3 and then fastened and fixed by a plurality of the straight pieces 6 and the reinforcing neck 6 And one side of the hinge 7 is fastened to the inner side surface of the door frame 2 with the directing piece 8 and the other side of the hinge 7 is fastened to the door (not shown) 9 by means of a direct-connected piece (10).

Since the door 9 is heavy in weight and rotates about the hinge 7, the load is concentrated on the door frame portion to which the hinge 7 is fastened. Therefore, the direct-connected piece 8 for fastening the hinge 7 is made of a long straight-piece piece, but after passing through the door frame 2, it is tightly fastened to a part of the reinforcing neck 6 to form the hinge 7 and the door 9 So as to be able to withstand the load concentrated on the hinge 7 portion.

A plurality of fixing members 11 (anchors) are fastened to the side surface of the reinforcing frame 5 at predetermined intervals by the direct connection pieces 12 and the projections of the fixing member 11 projecting to both sides of the door frame 2 The part is bent in the direction of the wall 1 and then fixed to the wall 1 with the concrete nail 13 and the like and is joined with the filler 14 or the like between the wall 1 and the door frame 2, The mortar 15 or a closure member is formed on the side surface of the wall body 1 including the bent portion of the wall portion 15 and then a finishing material 16 such as wallpaper, tile, board or paint is applied thereon.

The reinforcing frame 5 is inserted into the concave groove formed in the door frame 2 and then fastened and fixed to the door frame 2 by about 20 straight-connected pieces 6, The fastening pieces 6 are fastened one by one to each other and fastening time is longer than 10 minutes according to the skill of the worker. Therefore, the labor cost is increased, the working time is increased, and the total cost is increased There is a problem that productivity is lowered.

In addition, in the case of a long straight-piece piece having a long length, it can be excessively projected. In the case of a short-length straight piece having a short length, the fastening strength is lowered, and the end portion thereof penetrates through the door frame 2 in accordance with the fastening angle There is a problem that protrusions are formed (generated) in the door frame 2 due to the fastening force and the aesthetic appearance of the door frame 2 is largely lowered even if the door frame 2 does not protrude or protrude outside the door frame 2.

In addition, in order to increase the fastening force of the direct-coupled pieces, the straight-fastened pieces are fastened to be inclined in the oblique direction instead of the vertical direction or horizontal direction, but they are fastened to the reinforcing frame portion composed of a smooth zinc- There are many difficulties in doing so.

In addition, the door frame 2 is injection-molded with synthetic resin (ABS or the like) to reduce the manufacturing cost, but is reinforced with a metal reinforcing frame, so that the length of the straightened piece 6 is also shortened so that the fastening force The portion of the door frame 2 around the periphery where the directing piece 6 is fastened and the portion of the reinforcing frame 5 are tightly adhered to each other but firmly adhered to each other at portions other than the straightening piece 6, The reinforcing frame 5 is detached or adhered from the door frame 2 in the case where the external force is applied or the bending, twisting or bending occurs, There is a problem in that the strength of the reinforcement is greatly deteriorated.

The door frame 50 and the door frame reinforcement frame 20 are tightly coupled to each other by tightly coupling the door frame 50 and the door frame reinforcement frame 20 using the detent engagement structure and the engagement structure formed respectively in the synthetic resin door frame 50 and the door frame reinforcement frame 20, And is rigidly coupled to the door frame 50 by a double (first and second) fastening structure composed of the step portions 24 and 25 and the grip-type fastening portions 39 and 40, Is formed on the bottom surface of the bottom portion 21 and is easily joined to the door frame 50 by the inclined surfaces formed on the jaw portions 24 and 25 and the engaging portions 39 and 40, 38 are prevented from slipping or falling off after they are coupled to the door frame 50, and because they do not use a drill piece or a self drill screw, the workability is simple, and the cost is greatly reduced. There is an advantage to be improved.

Further, since the strength of the door frame 50 is greatly improved and reinforced by the reinforcing frame 20 which is tightly coupled, the impact and / or noise generated when the door is closed is remarkably reduced, It is not necessary to fix the fastening piece and fastening step, and quick coupling is achieved, so that the coupling cost and the coupling time of the frame reinforcing frame 20 are greatly reduced, the workability is simple, .

The door frame 50 and the door frame reinforcement frame 20 are tightly engaged with each other by tightly coupling the door frame 50 and the door frame reinforcement frame 20 using the detent engagement structure and the engagement structure formed in the door frame 50 and the reinforcement frame 20, And the drill piece (Self drill screw) is not used, so that the workability is simple, the cost is greatly reduced, and the productivity is greatly improved.

In the present invention, since the direct-piece piece is not used, the strength of the fastening piece due to the excessive protrusion of the straight-piece piece or the use of the short direct-piece piece, and the strength of the fastening piece A conventional phenomenon such as the formation of protrusions on the door frame 50 is prevented, thereby preventing a poor installation and a deterioration of appearance.

The locking grooves 56 and 57 formed in the door frame 50 according to the present invention may have the same shape as the locking portions 39 and 40 or may be omitted as shown in FIG. When the structure of the engaging grooves 56 and 57 is omitted, when the door frame reinforcing frame 20 is forcibly inserted (engaged) into the engaging groove 51, the inclination? 3 (? 4) of the side portions 26 and 27 Some or all of the engaging portions 39 and 40 projecting outwardly of the side portions 26 and 27 by the torsion force are engaged while being forcibly inserted into the inner side surfaces of the supporting portions 58 and 59. [

Although the present invention has been described mainly for reinforcement of the door frame 50 for the convenience of explanation, it goes without saying that the present invention can be applied to reinforcement of a window frame.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It is self-evident to those of ordinary skill.
