Description

Window bracket {BRACKET FOR WINDOWS AND DOORS}

The present invention relates to a bracket for a window, and more particularly, to a window bracket for supporting a window frame of a window from an indoor side.

A window is a generic term for a window and a door, and after the window frame is seated and fixed in the opening of the building, a plurality of windows installed on the window frame can be opened and closed in a sliding, hinged, or tilting manner.

Recently, in buildings such as apartments, balconies are expanded to secure more space. Since the windows installed on the exterior walls during the balcony expansion process are larger and heavier than the thickness of the retaining walls constituting the exterior walls of the building, separate brackets are used to open the windows and doors. to be stably supported on the retaining wall.

As shown in Figure 1, the construction of windows used for balcony expansion, when the window frame 20 is seated on the retaining wall 10, since the width of the window frame 20 is larger than the upper surface width of the retaining wall 10, stable support For this, after fixing the bracket 30 on the indoor side of the retaining wall 10 so that it can be supported, the insulation 40, the gypsum board 50, and the gypsum 60 are added to the outside thereof to finish.

Here, since the bracket 30 must be able to sufficiently withstand the load of the window frame 20 , it must have excellent strength. For this purpose, conventionally, a bracket as shown in FIG. 2 is mainly used. As shown in FIG. 2 , the bracket 30 includes a first member composed of a horizontal support piece 110 supporting the bottom surface of the window frame 20 and a vertical support piece 120 vertically bent with respect thereto, and on the first member. It includes a second member 200 interposed between the upper end of the opening of the retaining wall 10 and the window frame 20 after being coupled. In particular, in the horizontal support piece 110 and the vertical support piece 120, both ends in the width direction are formed with bent portions 112 and 122 bent vertically with respect to each, which bears the load of the window frame 20 while It is formed so as not to deform.

On the other hand, the above-mentioned conventional bracket for windows has the following problems.

First, when installing the bracket, it is necessary to form a through hole and an anchor insertion hole to insert the fastening bolt and anchor respectively to fix the bracket to the bottom surface of the window and the wall. is lowered

Second, when the thickness of the horizontal support piece 110 and the vertical support piece 120 is increased in order to improve the structural value of the bracket, the overall manufacturing cost of the bracket increases due to an increase in material cost.

An object of the present invention is to solve the problems of the prior art described above, and an object of the present invention is to provide a window bracket that can further improve the supporting force for supporting the window frame while using a smaller amount of steel compared to the prior art.

3 schematically shows the configuration of a window bracket according to an embodiment of the present invention. As shown in Figure 3, the window bracket is formed by extending in the vertical direction from the window and door support 310 supporting the bottom surface of the window and door installed on the retaining wall of the building, and the window and door support 310, the wall height fixed to the side wall of the retaining wall. It may be configured to include the government 320 . Here, it is preferable that the window and door support part 310 and the wall fixing part 320 are formed of a plate-shaped steel material.

A through hole 312 may be formed in the central portion in the width direction of the window and door support 310 to be fastened and fixed to the bottom surface of the window with a fastening bolt. In addition, an anchor insertion hole 322 may be formed in the central portion of the wall fixing part 320 in the width direction to fasten the anchor to the side wall of the retaining wall. In addition, bent portions 311 and 321 may be formed on both edges of the window support portion 310 and the wall fixing portion 320 , respectively.

In addition, a first groove 313 extending in the longitudinal direction from the central portion in the width direction and concave inward is formed in the window and door support unit 310 . Similarly, a second groove 323 is formed to extend along the longitudinal direction of the wall fixing part 320 around the area where the anchor insertion hole 322 is formed and to be concave inwardly.

The edges of each of the first groove 313 and the second groove 323 are preferably formed to be curved from the base panel constituting the window and door support part 310 and the wall fixing part 320 . That is, by making the edges of each of the first groove 313 and the second groove 323 formed to have a curved profile without being angled, the structural value of the window bracket, which will be described later, is improved and the mold operation is facilitated. can do. The above-described window and door bracket may be formed by pressing a substantially rectangular steel panel, or may be formed by an injection process through a mold.

If the above-described window and door bracket assembly is used, even if a bracket formed of a smaller amount of steel material is used compared to the conventional bracket for windows and doors (see FIG. 2 ), the supporting force for the window and door can be further improved. That is, in the prior art, in order for the bracket to support the load on the windows and doors, the horizontal bending part 112 and the vertical bending part 122 are formed by bending both sides in the width direction of each of the horizontal support piece 110 and the vertical support piece 120 . did. However, the inventors of the present invention have found that the most vulnerable part is the part where the anchor is installed when supporting the window through the bracket, and even if a small amount of steel is used, the maximum load of the bracket in the critical section is improved The window bracket structure of the present invention was designed so that

4 shows the bracket of the present invention (Example 1) and the conventional bracket (comparative example; see FIG. 2), respectively, when the same reaction force (Pw) is applied to the bracket in the critical section. Indicates the maximum load. Here, the same steel material (SS400 Steel) was used in Example 1 and Comparative Example, and the remaining conditions were calculated in the same manner except for differences in the structure of the brackets according to Example 1 and Comparative Example. 4, in the case of Example 1, the maximum load (MB) that the bracket can withstand in the limiting section is 220 kgf, but in the case of the comparative example, it can be seen that the maximum load that the bracket can withstand in the limit section is 167 kgf. Therefore, it can be seen that in the case of the example, the bearing capacity is improved by about 32% or more than that of the comparative example. Here, each maximum load (MB) was calculated under the same load applied to the limiting section. That is, when used in the same environment, it can be seen that the window bracket according to the embodiment has a better structure value than that of the comparative example.

On the other hand, the width direction W1 of each of the first groove 313 and the second groove 323 is 30 to 50% of the width direction width W of the base panel 320a of the wall fixing part 320 . It is preferable to have For reference, in the case of Example 1, the width W1 of the second groove 323 is formed in a dimension of 40% with respect to the width W of the base panel 320a of the wall fixing part 320 in the width direction. to be. When the width W1 of the second groove 323 is less than 30% or greater than 50% with respect to the width W of the base panel 320a, the structural value improvement effect by the second groove 323 is is decreased In addition, in FIG. 4, the protrusion height T1 at which the second groove 323 protrudes inward from the base panel 320a is preferably 30% to 70% with respect to the thickness T of the base panel 320a. , when the protrusion height T1 is less than 30% or more than 70% with respect to the thickness T, the effect of improving the structure value by the second groove 323 is reduced. For reference, in the case of Example 1, the protrusion height T1 of the second groove 323 is an example formed in a dimension of 50% with respect to the thickness T. As shown in FIG. In addition, although only the cross section of the wall fixing part 320 is shown in FIG. 4 , the window and door support part 310 and the first groove 313 formed therein are also formed in the same size and shape.

As can be seen from Figure 4, even if the same steel is used, it is possible to significantly improve the maximum load of the window bracket supporting the window. This means that it is possible to reduce the total amount of steel required for manufacturing the window bracket that satisfies the structural value required in the same working environment, and ultimately, the manufacturing cost of the window bracket can be reduced.

On the other hand, in order to further improve the maximum load while using the window bracket according to Example 1 as it is, it is also possible to use the structural reinforcement pad together as shown in FIG. 5 . That is, as shown in FIG. 5 , the window bracket according to the present invention may further include a structural reinforcement pad 400 attached to one side of the wall fixing part 320 . Here, an auxiliary anchor insertion hole corresponding to the anchor insertion hole 322 provided in the wall fixing part 320 may be formed in the structural reinforcement pad 400 in the central portion in the width direction. Then, the third groove 410 is formed concavely inward along the longitudinal direction around the area in which the auxiliary anchor insertion hole is formed.

6 shows the bracket of the present invention (Example 2) and the conventional bracket (comparative example; see FIG. 2), respectively, when the same reaction force (Pw) is applied to the bracket in the critical section. Indicates the maximum load. Here, Example 2 and Comparative Example used the same steel material (SS400 Steel), and the remaining conditions were calculated in the same manner except for differences in the structure of the brackets according to Example 2 and Comparative Example. Referring to Figure 6, in the case of Example 2, the maximum load (MB) that the bracket can withstand in the limiting section is 392 kgf, but in the case of the comparative example, it can be seen that the maximum load that the bracket can withstand in the limiting section is 167 kgf. Therefore, in the case of Example 2, it can be seen that the bearing capacity is improved by about 134% or more than that of the comparative example. Here, each maximum load (MB) was calculated under the same load applied to the limiting section. That is, when used in the same environment, it can be seen that the window bracket according to Example 2 has a better structure value than that of the comparative example.

For reference, Example 2 is substantially the same as Example 1 except that the structural reinforcement pad 400 is additionally used. However, it is preferable that the outer radius of curvature R2 of the third groove 410 is greater than the inner radius of curvature R1 of the second groove 323 . In Example 2 shown in FIG. 6 , R1 was 21.67 mm and R2 was 27 mm. In such a structure, it can be confirmed that the second groove 323 and the third groove 410 can be mounted in a spaced apart state at the part where the anchor is inserted, through which the maximum load of the window bracket can be further improved. can
