Description

The edge reinforcement body able to be fixed closely and The structure and method of reinforcement for welding type window frames using the same}

The present invention relates to a tightly fixed edge reinforcement and a reinforcing structure and a method of reinforcing a welded window frame using the same. In detail, the present invention relates to a window-related technology for improving the structural strength and wind pressure resistance of a window sill by inserting a tightly fixed edge reinforcement material into a guide groove existing at the corner of the window sill to firmly reinforce the edge of the window sill frame.

Windows and windows (including door frames) and windows (including doors) are made of plastic windows and aluminum windows depending on the material. Aluminum windows are mainly used for the windows that make up the exterior walls of large high-rise buildings that require structural strength. However, because of their high price, synthetic windows are widely used in the windows of buildings.

Synthetic resin windows are classified into welded windows and prefabricated windows according to the connection method of window frames. A welded window refers to a window that is made by cutting the window frame 45 degrees and thermally fused the cut surface thereof. A prefabricated window refers to a window that is assembled through a connector without heat fusion or a piece of window frame directly assembled.

On the other hand, in the case of installing large windows, welded windows have become more recently due to the fact that despite the convenient on-site assembly of prefabricated windows, it has a fatal flaw of leaking and that the attachment of interior films or decor sheets is not smooth. Is preferred.

In general, the synthetic resin window frame used for the manufacture of windows and doors to form a hollow portion in order to reduce the material and reduce its own weight, and insert the reinforcement of the metal material to prevent the deformation such as the window frame is bent or broken, have.

In residential spaces such as high-rise apartments and officetels, large windows and doors are being installed in the living room to connect with the veranda to secure the view and the view. The role of the metal reinforcement applied to such a large sized synthetic resin window affects not only the stability of the window structure but also the stability of the building structure, and its importance is increasing day by day.

However, in the case of prefabricated windows, various methods for inserting and reinforcing the corner reinforcement into the windows frame (Registration Utility Model Nos. 0283737, 0279187, 0362219, 0341295, 0360560, etc.) have been proposed. However, in the case of welded windows, the thermal stability between the window frames is practically impossible when the metal reinforcement is inserted in the corners, so the structural stability of the edges of the welded windows can only depend on the welding strength. . Due to this, the internal reinforcement inserted into the window frame is broken in the continuity of the welded edge portion is the structural weakness of the weld of the window edge, which leads to the fragility of the window structure itself.

In fact, welded windows have a problem that welded parts often fall during transportation or lifting, and there is a problem that the construction of the windows and doors does not improve the stability and wind pressure resistance.

In order to remedy this problem, Korean Utility Model Registration Nos. 416683, 428780, and 428785 insert corner reinforcements of solid metal into the guide grooves present at the edges of welded windows, through the fasteners or frame reinforcement. A method of reinforcing the corner portion by fixing with is proposed.

However, the edge reinforcement proposed by the above-described registered utility model is mainly made of a metal material in order to maintain the strength. Unlike the frame reinforcement, the edge reinforcement of the metal material exposed to the outside is exposed to rain water, etc. There is no choice but to be vulnerable. In particular, when rainwater flows through the fastener or the corrosion is transmitted, the frame reinforcement may be corroded.

In addition, there is a problem in reducing the work stability and efficiency, such as putting a hand on the wing of the reinforcement during the reinforcement work.

In addition, the corner reinforcement, window frame, frame reinforcement is all made of a solid material, their combined state is also vulnerable to vibration, etc. also coupled through a solid fastener. That is, since the rigid material without elasticity is not absorbed by the external force and is transmitted to the coupling portion of the end as it is, cracks may be generated at the coupling portion or the coupling state may be separated and the coupling portions may be spaced apart from each other. Can harm.

On the other hand, registration utility model Nos. 428780 and 428785 use fastener connectors, but even in this case, between the guide groove of the window frame and the corner reinforcement except the fastener, the solid material is also in contact with each other, and the problem still remains. May occur. In particular, even if the edge reinforcement is manufactured to the guide groove dimensions of the window frame, an error in the dimension may occur, and in this case, the edge reinforcement may be loosely inserted or excessively press-fitted, which may weaken the joining portion due to long vibrations. have. In addition, in the case of using the corner reinforcement of the metal material, due to the difference in the coefficient of thermal expansion with the window frame of the synthetic resin material may be weakened in the season when the crossover is severe.

On the other hand, in the welding synthetic resin window production process, weld sludge (aka welding dung) protrudes and hardens on the fusion surfaces of the heat-sealed horizontal and vertical frames. Welding sludge should be removed using a chisel.

However, it is best not to remove the weld sludge to maintain the welding strength, and if it is removed incorrectly, the welding sludge may damage the internal welding part such as opening the welding part. In the case of the type windows, the joint strength of the edge is dependent on the welding strength, so if the welding area is damaged, it may cause serious problems in the durability of the window. It is time consuming to do so, and this decreases work efficiency. Therefore, if the edge reinforcement can be tightly coupled to the window frame guide groove without removing the welding sludge, the work process will be significantly shortened while preventing the weld strength from dropping.

In order to solve the problems of the prior art as described above, the present invention can prevent corrosion due to rain water while maintaining the strength of the edge reinforcement and ensures the stability of the work, and joints with the window frame guide grooves in the vibration due to external force And to provide a window frame reinforcement technology that the fastening portion can maintain a close coupling state.

As a result, the soft coating material coated on the reinforcing core material can prevent corrosion due to rainwater, and can improve the stability of the work.The elasticity of the coating material closely fixes the edge reinforcing material to the window frame frame groove to absorb vibration of the window frame. This can improve the durability and wind pressure resistance of the window as well as the reinforcement function of the window edge.

In addition, another tightly fixed edge reinforcing material of the present invention is a reinforcing material for reinforcing the corner portion of the welded window frame frame by fusion bonding the horizontal and vertical frame having a guide groove, a rigid reinforcement core material; And a soft covering material for inserting the reinforcing core material, wherein the reinforcing core material is inserted into the covering material so as to be in close contact with the edge guide groove of the window frame to the horizontal and vertical frames through fasteners.

At this time, the tightly fixed edge reinforcing material, it is more preferable that the side portion of the L-shaped inner surface has a wing portion which extends all or part so as to be in close contact with both sides of the corner guide groove of the window frame.

As a result, it is possible to support not only the inner surface of the guide groove but also both sides, so that it is possible to form a reinforcement structure of the window and door which can effectively cope with not only the external force in the horizontal and vertical directions but also the shear force due to the external force in the other direction.

As a result, when the window sill is coupled to the window frame while the edge reinforcement is inserted and fixed, the sliding motion of the window sill does not be prevented.

The reinforcing core member and / or covering member of the tightly fixed edge reinforcing member of the present invention is characterized in that the portion in contact with the welded portion of the window frame edge portion is formed with a concave groove.

Thus, by forming a concave groove in the edge reinforcing material in contact with the weld sludge, the edge reinforcing material can be fixed in close contact with the guide groove without removing the welding sludge.

In addition, the tightly fixed edge reinforcing material of the present invention, the reinforcing core material may be coated by injection molding with synthetic resin or natural resin.

1 is a view showing the corner portion of the window frame formed by fusion of the horizontal and vertical frame. Specifically, it is a welded window frame applied to an unknown window.

As shown, the window frame 100 has a guide groove corresponding to the guide rail of the window frame frame (not shown), and may have a hollow portion communicating in the longitudinal direction. The welded window sill forms the horizontal and vertical frames by diagonally cutting the window frame (usually 45 degrees), as shown, by thermally fusion bonding the cut surfaces.

A hollow frame reinforcement (not shown) is usually inserted into the hollow part of the window frame to reinforce the window frame. In a welded window, a heat-sealing process is required. Could not be inserted.

In order to solve this problem, a method of reinforcing by inserting a corner reinforcing material into the guide groove of the window edge portion (Registration Utility Model No. 416683, No. 428780, No. 428785) has been proposed, but such a conventional reinforcing method, as described above, Due to the coupling between the rigid materials, there was a problem that the durability is weak, such as being weak to vibration and exposed to rain, etc., and the welding strength due to the welding sludge removal before the edge reinforcement is inserted and the work process is added.

Hereinafter, the tightly fixed edge reinforcement of the present invention for solving this problem will be described in detail with reference to FIGS.

2 is a view showing a reinforcing core of the edge reinforcing material according to an embodiment of the present invention, Figure 3 is a view showing a tightly fixed edge reinforcing material coated with the reinforcing core of Figure 2 through the injection process.

As shown in FIG. 3, the tightly fixed edge reinforcing member 300 of the present invention is formed by coating a reinforcing core material such as a metal material (dotted portion 310) with a soft covering material 330, and the edge reinforcing material 300 is a window sill. Inserted to be in close contact with the edge guide groove of the frame is fastened to the horizontal and vertical frame through the fastener.

When the corner reinforcement member 300 of the present invention is inserted into the guide groove of the window frame, the reinforcing core member of the metal material is exposed to rainwater or the like by the soft covering member 330 coated on the reinforcement core member 310 and the rainwater is fastened. It can prevent the seeping through the sphere, and can also solve the problem of cutting hands on sharp wings or corners. In addition, the edge reinforcing member 300 is tightly fixed to the window frame guide groove by the elasticity of the covering member 330 coated on the reinforcing core material to absorb the vibration of the window window, thereby improving the wind resistance of the window window.

As a result, the tightly fixed edge reinforcement of the present invention can further improve the durability of the window edge, as well as the durability and wind pressure resistance of the window, and also ensure the stability of the work.

In FIG. 3, the reinforcing core material 310 covered by the covering material 330 is illustrated in FIG. 2. The reinforcing core material 310 may be made of a reinforced plastic material in addition to the metal material, but it is more preferable to use a metal material having a high strength.

The edge reinforcing member 300 may generally be coated by injection molding the reinforcing core 310, but is not limited thereto. As described below, the edge reinforcing member 300 may be formed by inserting a reinforcing core into the coating.

The coating material 330 may be made of resin such as rubber, and in particular, thermoplastic synthetic resin may be used. However, the present invention is not limited thereto, and various materials may be used as long as the material has soft elasticity.

In FIG. 3, the entirety of the reinforcing core 310 is covered by the covering 330, but a part of the reinforcing core 310 may be covered by the covering 330. However, even in this case, it is preferable that at least a portion of the portion contacting the window frame arbitrary guide grooves is covered, and in the case where a metal reinforcing core is used, it is preferable to cover the entire reinforcing core to prevent corrosion.

The reinforcing core 310 and the edge reinforcing member 300 shown in Figures 2 and 3 has a wing portion extending the side of the inner surface and the inner surface of the L-shape in contact with the inner surface of the guide groove of the window frame. The edge reinforcing member 300 having such a shape can support not only the inner surface of the guide groove but also both sides thereof, so that the edge reinforcing member 300 can effectively cope not only with the external force in the horizontal and vertical directions but also with the shear force due to the external force in the other direction. Wind pressure can be improved.

The tightly fixed edge reinforcement of the present invention may be manufactured in various shapes in addition to the shapes shown in Figures 2 and 3, it is preferable that the shape satisfies at least the following conditions.

That is, the edge reinforcing member of the present invention preferably has an L-shaped inner surface that can be in close contact with the bottom of the guide portion of the corner frame of the window frame, and the L-shaped inner surface is more preferably made of a covering material. This is because the window frame and the edge reinforcement may be tightly coupled when the covering surface of the edge reinforcement may be closely adhered to the bottom of the guide groove, thereby exerting a reinforcing effect.

In addition, the corner reinforcement of the present invention, it should have a size and shape that is inserted into the guide groove of the window frame frame and does not interfere with the sliding movement of the window window. To this end, when the corner reinforcement of the present invention is coupled to the window frame in the state fixed to the window guide guide groove, it should not overlap with the guide rail of the window frame, that is, the locking dimensions (when the window guide is coupled to the window frame, the guide groove and window frame of the window frame It is preferable that the guide rail is located outside the range). In addition, as shown in Figure 11, even if the wing portion formed in the edge reinforcement 300 is within the locking dimension range, the distance between the wing portion should be larger than the thickness of the guide rail 206 of the window frame.

The size and shape of the corner reinforcement of the present invention preferably satisfies the above-described conditions, and various shapes can be changed within the limits satisfying the above-described conditions and the characteristic functions of the present invention.

2 and 3, the reinforcing core 310 or / and covering member 330 of the edge reinforcing member 300 is preferably formed with a concave groove in which the contact portion of the window frame edge is in contact with the welded portion.

Thus, by forming a concave groove in the edge reinforcing material in contact with the weld sludge, the edge reinforcing material can be fixed in close contact with the guide groove without removing the welding sludge.

As shown in FIG. 3, the groove formed in the portion contacting the weld portion should be formed in the reinforcing core material 310 but need not be formed in the cover material 330. This is because the covering material is a material having a soft elasticity, so that when the cover material is inserted into the guide groove of the window frame, it may be pressed in contact with the protruding welding sludge to be more closely coupled.

4 is a view showing a separately prepared coating material, Figure 5 is a view showing a corner reinforcing material formed by sandwiching the reinforcing core material of FIG.

As shown in Figures 4 and 5, the edge reinforcement of the present invention may be formed by inserting the reinforcing core 310 to the covering 330 after separately fabricating the covering 330 and the reinforcing core 310, respectively. .

The coating member 330 shown in FIG. 4 is provided with a protrusion and a groove into which the reinforcing core member 310 can be inserted. The reinforcing core member 310 is formed in the groove formed inside the protrusion by spreading the soft covering member 330 in the direction of the arrow. Combining in a fitted manner can form the edge reinforcement 300 shown in FIG.

The separately prepared covering member 330 may be manufactured in a state in which a fastening hole is formed in advance, but after coupling with the reinforcing core member 310 as shown in FIG. 5, the fastening hole is aligned with the fastening hole 319 of the reinforcing core member 310. 339) may be formed by drilling, or may be directly coupled to the fastener by fastening when fastening. The latter is preferred to prevent rainwater seeping through the fasteners.

Figures 6 and 7 show a tightly fixed edge reinforcement with an airtight member or stopper inserting means and / or a buffer functioning as a stopper, Figures 8 and 9 show a stopper that can be inserted into the inserting means of the edge reinforcement; It is a figure which shows an airtight member.

As shown in FIG. 6, the tightly fixed edge reinforcing member 300 of the present invention may include an insertion means 335 capable of inserting an airtight member or a stopper. As shown, the insertion means 335 is formed on the outer surface of the edge reinforcement 300, and is generally configured in the form of a protrusion or groove, but is not limited thereto, the insertion portion of the stopper or airtight member (reference numeral in FIG. 8). 505 and 605 of FIG. 9 may be configured by various means under the condition that they can be inserted.

The stopper 500 or the airtight member 600 illustrated in FIGS. 8 and 9 may be inserted into the insertion means 335 illustrated in FIG. 6 according to each application. In general, an airtight member is coupled to the insertion means formed on the lower or upper side of the window, and a stopper is coupled to the insertion means formed on the left and right sides of the window.

As such, the present invention can function as a stopper function or a windproof hair coupling function as one edge reinforcing material, so that there is no need to provide a separate stopper or a coupling means.

On the other hand, the frame reinforcement 700 may not be inserted.

The present invention having such a reinforcing structure, the reinforcing core 310 of the metal material by the coating member 330 can be exposed to rain or the like to prevent corrosion or seeping rainwater through the fastener, and is coated on the reinforcing core material 319 The edge reinforcing member 300 is tightly fixed to the window frame guide groove by the elasticity of the covering member 330 to absorb vibration of the window frame, thereby improving wind resistance of the window frame.

As a result, the reinforcement structure of the welded window sills of the present invention can further improve the durability and wind pressure resistance of the window sills as well as the reinforcement function of the window sills.
