The present invention relates to a fixing bracket for fixing the window frame to the outer wall of the building, and more particularly, is installed in the lower portion of the window frame, consisting of an outer support corresponding to the upper surface of the building and an inner support extending from the outer support to the interior side. Window frame support; And an A-shaped bracket formed of a window frame fixing portion coupled to the inner supporter and a wall fixing portion coupled to the outer wall of the building; It relates to a fixing bracket, characterized in that consisting of.

As the expansion of the balconies becomes legal, many attempts have been made to expand the balconies of buildings, including apartments, and in some cases, the balconies can be done in the form of this construction. However, the outside wall thickness of the balcony is about 12cm, while the wide balcony windows of the quadruple windows for insulation and soundproofing when the balcony is extended can be up to 320mm wide. Therefore, since the width of the extended balcony window frame exceeds the thickness of the outer wall it is necessary to install a separate bracket to support the window frame.

As a method for supporting an extended balcony window frame, conventionally, an L-shaped bracket is installed below the window frame along the outer wall as shown in FIG. 1. At this time, the upper horizontal portion of the L-shaped bracket is coupled to the lower part of the window frame using a screw, etc., the lower vertical portion is coupled to the outer wall through a fixing hardware such as pins, anchors. However, considering that the weight of the balcony including glass is 60kgf / ㎠ and the wind load corresponding to the external lateral load is about 450kgf / ㎠, the existing A-shaped bracket alone is insufficient to support the extended balcony window frame. . In other words, as time goes by, the center of gravity of the window frame gradually moves to the interior side, which causes the lifting of the window frame located on the outer wall, thereby increasing the instability of the building and the problems of defect repair.

In addition, in order to prevent the instability of the structure due to eccentric load, it is possible to consider increasing the number of A-shaped brackets, but this leads to an increase in the coupling hardware including the A-shaped brackets. There was a problem that it is difficult to guarantee window frame support.

In addition, the conventional expansion balcony window frame support method, first installed the upper horizontal portion of the L-shaped bracket in the lower part of the window frame, and then installed by fixing the lower vertical portion to the outer wall, in this case there is a gap between the fixing bracket and the outer wall In this case, there is a problem in that an additional process is required, such as a separate filler for filling the gap.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problem, and has a technical object to provide a fixing bracket capable of supporting the window frame stably and stably by preventing the lifting phenomenon of the windows due to the eccentric load.

Another object of the present invention is to reduce the installation location of the fixing bracket to improve the economics and construction.

Still another object of the present invention is to increase the construction convenience by installing the window frame support in the lower part of the window frame, and then placing it on the outer wall, completing the installation of the window frame by the horizontal movement of the L-shaped bracket.

In order to achieve the above object, the present invention is a fixing bracket for fixing the window frame to the outer wall of the building, which is installed in the lower part of the window frame, the outer support corresponding to the upper surface of the building and the inner support extending from the outer support to the interior side Window frame support; And an A-shaped bracket formed of a window frame fixing portion coupled to the inner supporter and a wall fixing portion coupled to the outer wall of the building; It provides a fixed bracket characterized in that the configuration.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

2 and 3 are perspective views showing an installation state of the fixing bracket and the fixing bracket according to the present invention, respectively.

As can be seen in Figure 2 (a) the present invention consists of a window frame support 30 and the A-shaped bracket (40). Here, the window frame support 30 is coupled to the lower portion of the balcony window frame 20, and consists of an outer support 32 coupled to the outer wall 10 and an inner support 34 extending inwardly from the outer support 32. do. At this time, the outer support 32 is more preferably extended to support the load than the position of the lower reinforcing core located in the lower window frame 20. Next, the A-shaped bracket 40 is composed of a window frame fixing part 42 and a wall fixing part 44. The window frame fixing portion 42 is coupled to the lower portion of the inner support 34, and the wall fixing portion 44 is directly coupled to the outer wall 10 by using nails, anchors, bolts, and the like.

In addition, the present invention is characterized by bending both ends of the window frame support 30 upward as shown in FIG. Here, both ends of the bent window frame butt 30 is a portion coupled to the lower part of the window frame 20, and a predetermined space is formed between the window frame 20 and the center portion except for both ends of the window frame butt 30. When the window frame support 30 and the A-shaped bracket 40 are coupled to each other, a bolt is inserted into a space formed between the window frame support 30 and the window frame 20, and then a fastening hole 50 formed in the inner support 34. After inserting the bolt through, it is coupled with the L-shaped bracket 40 by a nut. At this time, when the fastening hole 50 is configured as a slit hole, it is possible to simplify the construction of the window frame 20 regardless of the flatness of the outer wall (10).

On the other hand, as shown in Figure 2 (c) of the present invention, the inner support 34 is bent at both ends is provided with a guide rail 36, the sliding grooves 46 are formed on both upper ends of the wall fixing portion 44 In addition, the sliding groove 46 is sliding along the guide rail 36 includes a fixing bracket, characterized in that the wall fixing portion 44 of the L-shaped bracket 40 is fixed to the outer wall (10). Here, the guide rail 36 formed on the inner support 34 serves to guide the movement path of the L-shaped bracket 40 coupled to the lower portion of the inner support 34. The guide rail 36 may be manufactured in the form of coupling not only the inner support 34 but also a separate sliding groove at both ends of the inner support 34. The a-shaped bracket 40 is easily moved in the horizontal direction along the guide rail 36 formed in the window frame support 30 by using the sliding groove 46 is coupled to the outer wall 10. That is, in the present invention, after the window frame support 30 is coupled to the lower portion of the window frame 20 at a predetermined interval, and installed it on the outer wall 10, the sliding groove formed in the wall fixing portion 44 of the A-shaped bracket 40 It is possible to firmly install the window frame 20 only by the process of horizontally moving along the guide rail 36 using the 46. Here, since the A-shaped bracket 40 is inserted at the end, even when the flatness of the outer wall 10 is uneven, the window frame 20 may be installed without forming a gap between the outer wall 10 and the fixing bracket.

On the other hand, in the case of the installation method of the existing window frame 20 in relation to the load support may be inclined toward the inner support portion, in the present invention, the inner support portion and the outer support portion load based on the inner surface of the outer wall 10 Since the size of the maximum moment generated in the window frame support portion is reduced by the divided transmission, it is possible to stably support the load and reduce the installation location of the fixing bracket. That is, in addition to the coupling force of the existing wall fixing part 44 and the outer wall 10, the coupling force of the outer support portion and the outer wall 10 is added, so that the window frame 20 can be more stably supported.

In addition, the present invention is characterized in that a plurality of fastening holes 50 are formed in the window frame support 30 and the A-shaped bracket 40, the fastening holes 50 may be configured as a slit hole. In this case, when the coupling point of the outer wall 10 and the window frame support 30 or the A-shaped bracket 40 is increased, the coupling force is increased.

While the invention has been described in connection with the preferred embodiment as mentioned above, various modifications and variations are possible without departing from the spirit of the invention. Therefore, the claims of the present invention include modifications and variations that fall within the true scope of the invention.
