Description

Window Bracket{BRACKET FOR WINDOWS AND DOORS}

The present invention relates to a bracket for windows and doors, and more particularly, to a window and bracket which supports the window frame of the window from the indoor side.

Window is a generic term for a window and a door, and is configured so that a plurality of windows installed on the window frame can be opened and closed by sliding, opening, or tilting methods after the window frame is seated and fixed to the opening of the building.

Recently, a balcony is expanded in a building such as an apartment to secure a wider space. Since the window installed on the outer wall in the process of expanding the balcony is larger and heavier than the thickness of the retaining wall that constitutes the outer wall of the building, a window using a separate bracket is used. Is to be stably supported on the retaining wall.

As shown in Figure 1, the construction of the windows and doors used to extend the balcony, when the window frame 20 is seated on the retaining wall 10, the width of the window frame 20 is greater than the width of the upper surface of the retaining wall 10, stable support For this, after fixing the bracket 30 to the indoor side of the retaining wall 10 to support it, it is made in such a way that the insulation 40, gypsum board 50, and gypsum 60 are put on the outside to finish.

Here, the bracket 30 must be able to withstand the load of the window frame 20, so it should be excellent in strength. To this end, conventionally, a bracket as shown in FIG. 2 is mainly used. As shown in FIG. 2, the bracket 30 includes a first member and 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 bent vertically thereto. After being combined, the second member 200 is interposed between the top of the opening of the retaining wall 10 and the window frame 20. In particular, on the horizontal support piece 110 and the vertical support piece 120, both ends of the width direction are formed with bent portions 112 and 122 bent vertically with respect to each other, which while supporting the load of the window frame 20 It is formed to prevent deformation.

On the other hand, the above-described conventional window and bracket has the following problems.

First, the bent portions 112 and 122 provided to improve the strength of the bracket supporting the window frame are approximately 10 to 20 mm in bending height (ie, horizontal) from the horizontal support piece 110 and the vertical support piece 120, respectively. It has a support piece 110 or a height projecting from the vertical support piece 120, because of this, due to the protruding bent portions 112 and 122 when filling the insulation 40 in the empty space under the window frame 20 Since an empty space is generated between the bracket 30 and the heat insulating material 40, the heat insulating effect may be reduced.

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

Third, the bracket is usually formed of a steel material, and condensation is likely to occur between the retaining wall 10 and the bracket 30 due to the temperature difference between the outside air and the inside air, and this causes water droplets to flow into the gaps of the window frame 20. Since it is impregnated into the inner wall of the building and the paper, there is a problem of mold or water flowing down.

The present invention is to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a window bracket that can improve the support force supporting the window frame while using a smaller amount of steel.

Furthermore, another object of the present invention is to provide a prefabricated window and window bracket that can be used to assemble and use conveniently in accordance with the conditions of the construction site, while preventing condensation from occurring between the steel material bracket and the retaining wall.

In addition, the numbers (for example, first, second, etc.) used in the description process of the present specification are only identification symbols for distinguishing one component from other components.

Hereinafter, with reference to the accompanying drawings will be described in detail for the practice of the present invention.

Figure 3 schematically shows the configuration of the window and bracket according to the present invention. As shown in FIG. 3, the window bracket may include a front bracket 300, a condensation prevention pad 400, and a structural reinforcement pad 500.

The front bracket 300 includes a window support part 310 supporting a bottom surface of a window installed on a retaining wall of a building, and a wall fixing part 320 formed to extend vertically from the window support part 310 and fixed to a side wall of the retaining wall ). Here, the window support portion 310 and the wall fixing portion 320 is preferably formed of a plate-shaped steel material.

The window support part 310 may be formed with a long hole 312 extending in a direction in which the window protrudes toward the indoor side and a hole 313 for fastening a reinforcing screw to be fastened and fixed with a screw on the bottom surface of the window. . In addition, an anchor insertion hole 321 may be formed in the wall fixing part 320 to fasten the anchor to the side wall of the retaining wall. In addition, a through hole 323 through which the fastener 423 provided in the vertical pad 420 of the condensation prevention pad 400 to be described later may pass may be formed in the wall fixing part 320.

Meanwhile, a pair of corner reinforcement pieces 340 are formed to face each other in the corner area between the window support part 310 and the wall fixing part 320. The edge reinforcement piece 340 is preferably formed perpendicular to each of the window support portion 310 and the wall fixing portion 320. The edge reinforcement piece 340 is for improving the bending strength of the window support portion 310 and the wall fixing portion 320, and when forming the window supporting portion 310 and the wall fixing portion 320 using a steel panel, The window support part 310 and the wall fixing part 320 may be formed by cutting a portion of both corner areas of the contact area and then bending the inside part. Preferably, when forming the front bracket 300, after punching the long hole 312, the hole 313, the anchor insertion hole 321 and the through hole 323 in the steel panel, a punching process using a press Through the window support 310, the wall fixing portion 320 and a pair of corner reinforcement pieces 340 can be formed at the same time.

Next, the anti-condensation pad 400 includes a horizontal pad 410 covering the upper surface of the window support part 310 and a vertical pad 420 covering one surface of the wall fixing part 320 connecting to the side wall of the retaining wall. It may be configured to include. Here, the condensation prevention pad 400 including the vertical pad 410 and the horizontal pad 420 is preferably formed of a synthetic resin material.

The anti-condensation pad 400 prevents the front bracket 300 made of steel from directly contacting the retaining wall to prevent condensation. The condensation prevention pad 400 may be formed through an injection process using a synthetic resin material. Condensation prevention pad 400 may be fastened with the front bracket 300, for example, a guide rail 414 may be formed on the horizontal pad 410 such that both edges 311 of the window support part 310 are inserted and coupled. have. To this end, the distance between the pair of edge reinforcement pieces 340 formed in the window bracket 300 is smaller than the distance between the opposite edges 311 of the window support 310 (ie, the width of the window support) It is preferred. Thus, when fastening the front bracket 300 to the condensation prevention pad 400, the edge 311 of the window support portion 310 protruding outward of the edge reinforcement piece 340 is fitted to the corresponding guide rail 414. Can lose.

Meanwhile, a plurality of long holes 412 and 413 may be formed at positions corresponding to the long holes 312 and the holes 313 provided on the window support part 310 on the horizontal pad 410. Therefore, after fastening the front bracket 300 to the condensation prevention pad 400, the window bracket can be fastened and fixed using screws on the bottom surface of the window.

In addition, an anchor insertion hole 421 is formed in the vertical pad 420. In addition, a fastener 423 may be formed in the vertical pad 420. The fastener 423 may be formed of a pair of fastening pieces 423a spaced apart at predetermined intervals. The fastener 423 is formed to protrude through the through hole 323 provided in the wall fixing part 320. The protruding fastener 423 is fitted into the fastening hole 523 provided on the structural reinforcement pad 500 disposed on the other surface corresponding to one surface of the wall fixing part 320 on which the vertical pad 420 is disposed.

The structural reinforcement pad 500 is a plate-shaped reinforcing material formed of a steel material, wherein the fastening hole 523 is formed with an anchor insertion hole 521 into which an anchor is inserted. A fastening hole 423 formed in the vertical pad 420 is fastened to the fastening hole 523 formed in the structural reinforcement pad 500 in a forced fitting manner. Particularly, when the fastener 423 is fitted into the fastening hole 523, the distance between the pair of fastening pieces 423a spaced at a predetermined interval is narrowed and then inserted into the fastening hole 523, and then expanded again. Thereby, the locking portion 423b formed at the end of the fastening piece 423a is caught in the fastening hole 523 and is firmly fixed.

As described above, in the window and bracket according to the present invention, the front bracket 300 is first fastened to the condensation prevention pad 400 in the “A” direction, and then the structure is reinforced using the fastener 423 and the fastening hole 523. By fastening the pad 500 to the assembly in which the front bracket 300 and the condensation prevention pad 400 are combined, the final window bracket can be completed. At this time, the vertical pad 420 is formed to extend vertically from the inside of the horizontal pad 410, in order to improve the structural stability of the vertical pad 420, support between the vertical pad 420 and the horizontal pad 410 The piece 401 can be further formed. Furthermore, when fastening the anti-condensation pad 400 to the front bracket 300, the fastener 301 may be formed at a corresponding position of the front bracket 300 so that the support piece 401 can be fitted. In addition, the horizontal pad 410 may include an extension portion 410a extending in a direction opposite to the direction in which the front bracket 300 is disposed, and the extension portion 410a is interposed between the top surface of the retaining wall and the bottom surface of the window. Can be. A predetermined long hole 413a and a hole 412a may be formed in the extension portion 410a so as to be fastened with a screw on the bottom surface of the window. The final assembly of the window and bracket according to the present invention thus formed is illustrated in FIG. 4.

Window and bracket assembly according to the present invention shown in Figure 4, first can be temporarily fixed using screws on the bottom surface of the window. For example, the window bracket is screwed to the bottom surface of the window through the long holes 413a and holes 412a formed in the extension portion 410a, and the long holes provided in the window support portion 310 and the horizontal pad 410. Thereafter, the extension portion 410a is mounted on the upper end of the retaining wall, and at the same time, one surface of the vertical pad 420 is closely adhered to the indoor side wall of the retaining wall, and then securely fixed to the wall using an anchor. After that, the window is closed with an insulating material or the like in the empty space below the area protruding to the interior.

On the other hand, the size of the windows and doors installed in the building varies from manufacturer to manufacturer, and the dimensions of the windows protruding from the retaining wall to the interior are different depending on the construction environment. Therefore, having a plurality of window brackets having different dimensions according to the construction environment may increase manufacturing cost and also lower work efficiency. To this end, when supporting the bottom of the window through the window bracket, it is preferable to additionally provide an auxiliary horizontal pad so that the operator can adjust the length of the horizontal pad fixed to the bottom of the window according to the actual construction environment.

5 illustrates a state in which the condensation prevention pad 400 and the auxiliary horizontal pad 430 are combined for convenience of explanation. As shown in FIG. 5, the auxiliary horizontal pad 430 is formed with a second coupling hole 435 that can be fastened to the first coupling hole 415 provided at one end of the horizontal pad 410. In addition, the auxiliary horizontal pad 430 is formed with an auxiliary guide rail 431 into which both edges 311 of the window support portion 310 of the front bracket 300 are inserted and fixed. According to the construction environment of the site, the operator combines the auxiliary horizontal pad 430 of an appropriate length to the horizontal pad 410 of the condensation prevention pad 400, and then through the auxiliary guide rail 431 and the guide rail 414. Fasten the bracket 300 (see FIG. 3). After that, it is fixed to the bottom of the window through a plurality of holes 432 and long holes 433 provided on the auxiliary horizontal pad 430. Accordingly, when the auxiliary horizontal pad 430 is used, an operator can place the auxiliary horizontal pad 430, the anti-condensation pad 400, the front bracket 300, and the structural reinforcement pad 500 according to the size of the window according to the construction environment. It can be assembled in to complete the window and bracket assembly. Additionally, the auxiliary horizontal pad 430 may be formed using a synthetic resin material of the same material as the anti-condensation pad. In addition, the second coupling hole 435 provided on the auxiliary horizontal pad 430 has a structure that can be fastened to the first coupling hole 415 in a vertical direction, and in particular, has a structure that can be prevented from being removed in the horizontal direction. Is formed. This effectively prevents the auxiliary horizontal pad 430 from being separated from the horizontal pad 410 even when shear stress occurs in the horizontal pad 410 and the auxiliary horizontal pad 430 with respect to the vertical pad 420 fixed by the anchor. It is for sake. To this end, the second coupling hole 435 is preferably formed with protrusions 435a protruding on both sides, and the first coupling hole 415 to match the shape of the second coupling hole 435 provided with the protrusion 435a. ) May be formed.

When the above-described window and bracket assembly is used, even when using a bracket formed of a smaller amount of steel material than the conventional window and bracket (see FIG. 2), the support capacity for the window can be further improved. That is, in the related art, in order to support the load on the windows and doors, both sides of the horizontal support piece 110 and the vertical support piece 120 are bent in the width direction to form a horizontal bending part 112 and a vertical bending part 122. 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. In addition, even if a small amount of steel is used, the maximum load of the bracket in the critical section is improved. The window and bracket structure of the present invention was designed so as to make it possible.

6 is a bracket in the critical section (Critical Section) when the same reaction force (Pw) acts when supporting the window using the window bracket of the present invention (example) and a conventional bracket (comparative example; see FIG. 2) It represents the maximum load that can withstand this. Here, the same steel material (SS400 Steel) was used in Examples and Comparative Examples, and the rest of the conditions were calculated in the same manner, except for differences in the structure of the brackets according to the Examples and Comparative Examples. Referring to FIG. 6, it can be seen that, in the case of the embodiment, the maximum load (MB) that the bracket can bear in the limiting section is 275 kgf, but in the case of the comparative example, the maximum load that the bracket can bear in the limiting section is 167 kgf. Therefore, it can be seen that in the case of the example, the supporting force is improved by about 60% or more than the comparative example. Here, each maximum load (MB) was calculated under the same condition that the load applied to the limiting section was the same. 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 the comparative example.

In addition, although the portion that touches the upper surface of the open retaining wall is an extension portion 410a, which is a synthetic resin material in the embodiment, the second member 200 is formed of a steel material in the comparative example. As shown in the modeling analysis of the thermal insulation effect of FIG. 7, it can be seen that the portion where the extended portion 410a and the second member 200 are disposed is the most vulnerable portion to thermal insulation. In the present invention, since the extension portion 410a having a small structural role is formed of a synthetic resin material, the insulating effect may be further improved. For reference, as a result of the modeling analysis of FIG. 7, the outside temperature (OUTSIDE) was set to -18°C, the room temperature (INSIDE) was set to 21°C, and all other conditions were the same, followed by the window and bracket according to Examples and Comparative Examples. It is the result value measured after installation. As shown in FIG. 7, in the case of the embodiment, the temperature of the end of the inner bracket is 3.3°C, whereas in the case of the comparative example, the temperature of the end of the inner bracket is -4.9°C, which is about 8° C. higher than the comparative example. Can be seen. Through this, it can be seen that in the case of the present invention, the thermal insulation performance is improved compared to the prior art.

As described above, when using the window bracket according to the present invention, even when a smaller amount of steel is used, the maximum load of the bracket supporting the window can be significantly improved. Since the bracket increases the maximum load and uses a small amount of steel, it is possible to reduce the manufacturing cost. In addition, when a window is supported using a bracket, the support force for the window is improved, and at the same time, the steel material can be prevented from directly connecting to the retaining wall, thereby improving the insulation effect. Furthermore, the size of the anti-condensation pad is variably adjusted so that the contractor can assemble and use the anti-condensation pad, the front bracket, and the structural reinforcement pad in the field, making it easier to install windows using the window bracket.

The preferred embodiments of the present invention have been described so far, but those skilled in the art to which the present invention pertains may be implemented in a modified form without departing from the essential characteristics of the present invention. Therefore, the embodiments of the present invention described herein should be considered from a descriptive point of view rather than a limiting point of view, and the scope of the present invention is shown in the claims rather than the above description, and all differences within the equivalent ranges of the present invention It should be interpreted as being included in.
