The present invention relates to a foamed plastic door frame structure, and more particularly, to prevent bending deformation and cracks generated during extrusion molding, curing or cutting processing, and a structure that can be sufficiently constructed with only one door frame member without additional reinforcement material. The present invention relates to a foamed plastic door frame structure that provides rigidity and construction precision even without being fixed to a wall by nails.

 In general, the wooden door frame has the advantages of easy construction and processing work, and easy on-site processing work due to errors, while the cost is high due to the problem of being easily vulnerable to moisture and the regulation of forest damage.

As an alternative, door frames made of synthetic resins have been widely used, and the synthetic resin door frames 100 are formed by a plurality of hollow parts 110 by partition walls for material reduction and weight reduction during extrusion molding as shown in FIG. 1. Is to be formed.

However, such a conventional synthetic resin door frame has a different shrinkage rate due to the characteristics of the material itself, the formation of the hollow portion and the structure of the outer frame of the door frame does not break, and the temperature of the hollow portion side and the outside temperature during curing is different. Accordingly, there is a problem that the entire door frame is distorted or uneven and uneven, and there is a problem that the crack is generated when cutting after the extrusion and drawing process.

In addition, the conventional door frame having a hollow part has a very low bonding force with the wall mortar due to the smooth surface to be constructed, and it is difficult to expect a solid fastening effect due to the small end area supporting the nail even if it is nailed at the time of joining the wooden door frame. , There was a problem that the noise is greatly generated during the opening and closing operation of the door due to the hollow portion even when using the installation.

As shown in Fig. 2, the utility model registration No. 129028 proposes a solution to this problem.

That is, the step 110 is formed so that the opening and closing range of the door can be determined on one side of the upper surface, and the other side has a gentle slope so as not to be caught by the foot when entering and leaving the height difference with the floor surface of the building where the door frame is installed ( It is formed to form a 120, the nail hole 140 is formed between the step 110 and the inclined surface 120 to further solidify the binding force with the wall 400 by the nail 130, the lower surface of Figure 1 Unlike the conventional door frame of the door frame 100 having at least one groove (150a, 160a) is provided on the bottom surface 150 and the edge vertical wall 160 in the open state without a hollow portion,

The engaging protrusion 210a and the arc-shaped protrusion 210b are formed to fit in the grooves 150a and 160a of the door frame 100, and the bonding force of the mortar layer 300 applied to the wall 400 on the opposite side thereof. It is provided with a reinforcing member 200 is formed with a support rib 230, including a support leg 220 to increase the,

Mortar layer 300 to which the grooves 150a and 160a of the door frame 100 and the protrusions 210a and 210b of the reinforcement 200 are combined and then the reinforcement 200 is applied to the wall 400. It is the structure which made it settle in.

However, such a conventional door frame may have a significant technical advantage compared to the door frame of FIG. 1, but additionally, a manufacturing process time, a manufacturing cost, etc. were additionally required by a reinforcement provided separately from the door frame, and particularly, for fixing the door frame to a wall. There was another problem that the door frame is distorted if you escape from the exact hitting point when hitting the nail.

The present invention has been made to solve the above problems, its purpose is to prevent bending deformation and cracks generated during extrusion molding, curing or cutting processing, and can be sufficiently constructed by only one door frame member without additional reinforcement material The present invention provides a foamed plastic door frame structure that provides rigidity and construction precision even if the nail is not fixed to the wall.

In order to achieve the above object, the present invention forms a stepped 11 and a gentle inclined surface on the upper surface, the bottom surface between the edge vertical wall 13 is fixed to the wall 40 by the filling member 30 In the door frame made of a foamed synthetic resin material is composed of a plurality of fixing members 14 are integrally formed during extrusion molding, the fixing member 14 is a T-shaped (14-1) or to increase the adhesive force with the filling member (30) It provides a foamed synthetic resin door frame structure, characterized in that formed in the N-shaped (14-2) or a combination thereof.

In addition, the present invention for achieving the above object is characterized in that the band-shaped muscles are further installed to increase the bonding force and the filling member in the space between the wall when the door frame is constructed.

Hereinafter, the present invention will be described in more detail with the accompanying drawings.

As shown in FIGS. 3 and 5, the door frame 10 of the present invention has a step 11 formed as a kind of stopper to limit the opening and closing range of the door (not shown), and the bottom surface of the building at the side thereof. The upper surface configuration of the door frame 10 having a gentle inclined surface 12 so as not to be caught by the foot when entering and leaving with a small difference in height from the above is almost the same as that of the conventional one.

On the other hand, on the bottom of the door frame 10 between the edge vertical wall 13 orthogonal to the top surface, the filling member 30 is embedded in the reinforcing material, that is, the filling member 30 in the conventional door frame structure shown in FIG. It is a key point of the present invention to integrally form a plurality of fixing members 14 in the extrusion molding process instead of increasing the adhesion force with the a).

In addition, another essential aspect of the present invention is that the fixing member 14 of the present invention, which is composed of a plurality, is integral with the door frame, so that they are formed independently or individually without being connected or connected to each other. The reason is that the improvement in adhesion with the filling member 30 occupies the largest specific gravity, but by removing the hollow portion 110 of FIG. 1 so that the temperature deviation does not occur in any part of the door frame 10 during curing after extrusion molding. The same shrinkage rate is obtained every time.

In conclusion, the fixing member 14 may be configured as a T-shape 14-1 as a shape for increasing the bonding force with the filling member 30 as shown in FIGS. It can be formed in the form of), and it can also be a complex form that combines them.

In addition, the door frame 10 of the present invention may be blended with wood flour or chaff as an additive in order to increase the environmental friendliness and minimize the distortion deformation during curing, the mixing ratio is preferably about 20% by weight.

On the other hand, the door frame 10 of the present invention in addition to the nail 130 of Fig. 2 in addition to the space between the wall 40 and the construction at the bottom of each fixing member 14 and small on both side walls of the wall 40 By using a fastening member 22, such as a nail or bolt, by fixing the connection can be provided with a band-shaped muscle 20 to increase the bonding force and to provide a gap for the application of the filling member (30).

Referring to the construction and the effect according to the present invention configured as described above are as follows.

First, the installation place of the band-shaped muscle 20 is determined in a plurality of places having a constant equal interval on the bottom of the door frame 10 of the length material, and then the fixing part 14 of the door frame 10 is located at the center of the band-shaped muscle 20. ), Ie, both edge portions of the band-shaped muscle 20 after being fixed with a fastening member 22 such as a small nail or bolt against the bottom of the T-shaped fixing member 14-1 or the N-shaped fixing member 14-2. The band-shaped muscles are bent to form a U-shape and then fixed to the wall 40 by the fastening member 22.

 In this manner, the door is installed at the door frame position where the door is installed, and the band-shaped muscle 20 has a plurality of equally spaced intervals in the longitudinal direction.

Thereafter, as shown in FIG. 5, when the filling member 30, such as silicon or urethane, is applied through a gap between the edge vertical wall 13 of the door frame 10 and the wall 40, the door frame 10 and the wall ( 40 is inserted into the space between the 40 and gradually hardened to obtain a bonding force with the wall 40 and at the same time the fixing member 14 of the door frame 10, that is, the T-shaped fixing member 14-1 and the B-shaped fixing member 14 -2) Since the shape is taken to be able to face away from the detachment direction of the door frame 10, the bonding force becomes more robust.

Applying the present invention as described above has the following advantages.

First, in the conventional door frame structure, since the hollow part for weight and material reduction is formed and the inside and outside of the door frame are formed to be open to each other, the shrinkage of each part is constant during curing after extrusion molding to prevent deformation due to temperature deviation. Can,

Second, since the door frame structure is an open structure excluding the hollow part, it is possible to bend slightly according to its elastic force in the process of cutting to a certain length for productization after the drawing process, so that no crack occurs.

Third, compared with the conventional door frame using a reinforcement, by forming a fixing member integrally with the door frame to further increase the bonding force with the filling member, it does not require the need for a separate reinforcement or work time and labor costs for assembly,

Fourth, compared with the conventional door frame using reinforcement, it excludes the nail used to fix the door frame to the wall and installs a band-shaped root so that the nail may interfere with the door frame or even if it escapes from the exact point of impact when the nail is hit. Since the problem of breakage can be solved, there is an advantage in that convenience and stability and reliability in construction are realized.
