Abstract
The present invention proposes a door having sufficient heat insulating function and strength reinforcing function. The door of the present invention comprises an outer skin (10) having at least one side of a concave portion (14) recessed to form a pattern and a flat portion (17) forming the same plane on the inside and outside of the concave portion, And an inner skin (20); A urethane insulation layer 16 formed between the outer skin and the inner skin; And a frame (18, 18A, 19) interposed in a rim portion between the outer skin and the inner skin. A plurality of plate-like LVL reinforcing plates 22 are provided between the outer skin and the inner skin to reinforce the overall door strength. The thickness of the outer skin and the inner skin corresponding to the concave portion 14 is relatively thicker than the thickness of the outer skin and the inner skin corresponding to the flat portion 17, And reinforcement.
Description
The present invention relates to a door, and more particularly, to a door provided with a reinforcing structure using a laminated veneer lumber (LVL) to prevent intrusion of the outside, and a urethane insulating layer inside.
A commonly used GRP (Glassfiber Reinforced Plastic) door is generally composed of a pair of door skins molded using SMC (Sheet Molding Compound) and a urethane foam formed between these door skins . Here, the SMC used for the molding of the door skin includes various components including glass fiber for strength reinforcement.
As described in Korean Patent Laid-Open Publication No. 10-2012-58052, it is general to form a specific pattern on the front surface of such a GRP door (hereinafter, simply referred to as a door) to be. One of the methods of forming the pattern on the exterior surface of the door, particularly on the exterior of the house, is to form a concave line in the outer skin and to define the contour of the desired pattern (e.g., several squares or rectangles) .
However, as described above, forming a concave portion on the outer surface of a door made of an inner skin and an outer skin with a urethane layer interposed therebetween is a drawback that the door strength is substantially lowered. Such a door is used as a means for limiting or allowing the entrance of a house. If the strength of the door is lowered, the safety of the door can not be secured in terms of method such as an intrusion from the outside.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is a main object of the present invention to provide a door which is sufficiently reinforced in structure so that sufficient heat insulation is possible.
Another object of the present invention is to provide a door with good processability, such as a separate attachment, for example, in the middle part of the door.
It is still another object of the present invention to provide a door configured such that the flow of the urethane foam liquid for forming a heat insulating layer in the door is smooth.
The reinforcement of the structural strength of the present invention can be said to mean that it is possible to substantially prevent the damage of the door for intrusion from the outside substantially, and it has the same meaning as to provide a door that is advantageous from the perspective of crime prevention ultimately can do. The ease of machining a portion of the door means that the structure for attaching a separate attachment such as a mailbox can be easily processed, and that sufficient safety is ensured even if partial processing is performed . Further, the good flowability of the urethane foam liquid means that the internal structure is not changed or the skin is not deformed by the flow of the foamed liquid, and the heat insulating layer can be easily formed.
In order to achieve the above object, the door of the present invention comprises a concave portion formed concavely to form a pattern and a planar portion forming the same plane between the concave portion and at least one side of the concave portion, Skin and inner skin; A frame forming a rim portion between the outer skin and the inner skin; A heat insulating layer formed inside the frame by foaming a liquid foamed liquid injected between the outer skin and the inner skin; A reinforcing plate disposed between the outer skin and the inner skin at positions spaced apart from the outer skin and the inner skin by a predetermined distance and spaced apart from each other; And a support means for supporting the reinforcing plate at a position spaced apart from the outer skin and the inner skin with respect to the liquid foamed liquid injected between the outer skin and the inner skin. Here, in order to reinforce the strength of the outer skin and the inner skin, the thickness of the outer skin and the inner skin corresponding to the concave portion is relatively thicker than the thickness of the outer skin and the inner skin corresponding to the flat portion.
And the reinforcing plate of the present invention is preferably formed of LVL.
It is preferable that the reinforcing plate in the present invention is constituted by a plurality of the reinforcing plates which are provided on the flat portion between the concave portions formed on at least one side of the outer skin or the inner skin and are divided by the concave portions.
In the present invention, it is preferable that the supporting means for supporting the reinforcing plate is constituted by a position holding pin which is supported by both ends of the outer skin and the inner skin, respectively, while penetrating the reinforcing plate.
The door of the present invention has a door which is in contact with the inside of at least one of the pair of vertical frames and has a predetermined length in the up and down direction at an intermediate portion where the door handle is installed, And a vertical frame for reinforcement installed on the frame.
It is further expected that the reinforcing plate of the present invention is formed with a plurality of through holes through which the liquid foam liquid can pass.
The door according to the present invention having the above-described structure basically has a concave portion for forming various patterns on the skin forming the surface of the door. Even though the urethane insulation layer is thinned due to such concave portions, it can be seen that the door of the present invention can have sufficient strength by a plurality of reinforcing LVL reinforcing plates provided between the inner skin and the outer skin.
According to the present invention, the thickness of the concave portion of the skin molded to form the pattern on the door is set to be relatively higher than the thickness of the skin forming the plane. Therefore, it can be seen that the overall strength of the recessed portion is prevented from lowering at the molded portion, and the substantial strength of the door of the present invention is also increased by such a configuration. In this case, the fact that the strength of the door is increased means that the breakage time of the door for the intrusion becomes long when the intrusion occurs.
In the door of the present invention, a plurality of LVL reinforcing plates are fixed at the middle height thereof. The reinforcing plate substantially reinforces the strength of the entire door, and may improve the workability of the portion where the reinforcing plate is installed. For example, in order to install a separate attachment such as a mailbox or a window, the corresponding portion of the door must be machined. The portion where the LVL reinforcing plate is installed has a substantially thick thickness, It is expected to be prevented.
In addition, according to the present invention, the LVL reinforced plate has a merit that it is more advantageous for heat insulation. For example, the LVL reinforced plate has a sufficient heat insulating function as compared with a metal reinforcing part that can be adopted for reinforcement, It is more advantageous for insulation. Since the LVL reinforcing plate is a plate-like plate having a substantially constant area, it is considered to be more advantageous in preventing noise.
Further, it can be seen that the reinforcing plate of the present invention is substantially supported in the middle between the inner skin and the outer skin. Accordingly, the foamed liquid supplied through the space between the inner skin and the outer skin can be filled in a space between the inner skin and the outer skin while flowing smoothly and smoothly. The formation of the heat insulating layer as described above is expected to substantially contribute not only to lowering of the defective ratio but also to improvement of the heat insulating function. Further, it is expected that the flowability of the foamed liquid can be further improved by forming a plurality of through holes in the reinforcing plate.
