Description

Curtain wall device including joint sealing structure {CURTAIN WALL DEVICE INCLUDING JOINT SEALING STRUCTURE}

The present invention relates to a curtain wall device including a joint sealing structure, and more particularly, to a curtain wall device including a joint sealing structure that provides high-density sealing at a joint where a head member (vertical member) and a transom (horizontal member) forming a curtain wall are joined and at a joint with a sliding window frame applied to the curtain wall, thereby reinforcing watertightness, airtightness, insulation, and earthquake resistance.

In general, a curtain wall is a structure installed on the main structure of a building, which is made up of columns and beams, to support vertical and horizontal loads applied to the building from the outside.

This type of curtain wall system is composed of a frame structure for attaching and detaching finishing materials such as glass to the exterior walls of high-rise buildings, and has a horizontal part made of horizontal frames and a vertical part made of vertical frames, and double-glazed glass is installed using an adapter member attached to the frame.

In these curtain wall systems, the horizontal and vertical frames on which the double-glazed windows are installed are connected and fixed to each other through connecting members to reinforce the entire structure of the curtain wall system.

In addition, in the curtain wall system, the horizontal frame and the vertical frame that are orthogonally connected as a reinforcing skeleton are generally connected at the construction site by a method such as a direct piece connection or a bolt connection method using a bent bracket.

Curtain walls serve as partitions between the interior and exterior of a building, and are particularly popular in modern buildings for their decorative or interior purposes, especially when glass windows are used.

In addition, curtain walls serve to block rain and wind from the outside and block noise and heat, and walls that use glass and other materials without columns and beams being exposed to the outside have a great function as exterior walls.

In particular, it is widely used in high-rise or ultra-high-rise construction. For buildings over 100m in height, it is difficult to assemble scaffolding on the outside, so a method of lifting and attaching panels manufactured in advance at the factory is widely used.

The panels used in curtain walls are manufactured in factories, allowing for mass production. The panels are standardized and unified, which gives the building's exterior a new, industrial look.

Accordingly, aluminum curtain walls are being widely used in recent years as residential and commercial buildings become taller, but since aluminum is a metal, there is a problem that the joints where the horizontal and vertical frames meet have severe contraction/expansion, resulting in poor watertightness and airtightness, which can cause damage to the frame assembly due to water leakage caused by rainwater inflow.

In addition, the wind load acting on the frame assembly causes damage to the frame assembly and noise due to friction between metals, and even if separate silicone work is performed at the part where the horizontal frame and the vertical frame meet, cracks may occur at the joint due to thermal shrinkage and expansion of the metal, such as aluminum, and there is a problem that the work time and installation cost due to the silicone work increase, and if the silicone work conditions are not good, the work may not be done perfectly, resulting in gaps that may cause water leakage, or the appearance may not be attractive due to the messy silicone work.

Therefore, a method to solve these problems is required.

Republic of Korea Patent Publication No. 10-1045648

The present invention is an invention devised to solve the problems of the above-described prior art, and has the purpose of ensuring complete sealing of the joint area between the first frame (vertical member) and the second frame (horizontal member) forming the curtain wall and when a sliding window frame is applied to the curtain wall, thereby reinforcing watertightness, airtightness, insulation, and earthquake resistance.

The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above-described object, a curtain wall device including a joint sealing structure of the present invention comprises a plurality of first frames having a predetermined length and arranged vertically with respect to the ground but spaced apart from each other, a plurality of second frames provided between the plurality of first frames and coupled to form a horizontal direction with respect to the ground, a fixing member positioned at both inner ends of the second frames so as to fix the second frames to the first frames, and a blocking member attached between the first frame and the second frame and having an attachment position fixed by the fixing member, wherein the blocking member seals the joint portion of the first frame and the second frame to enhance watertightness, heat insulation, noise reduction, and earthquake resistance of the curtain wall device.

At this time, the fixed part may include a bracket module having one side that is in close contact with the other side of the blocking part that is in close contact with the first frame, and having both ends bent and inserted into the inside of the second frame, and a coupling unit that is penetrated and connected to the bracket module so that the second frame is coupled to the first frame.

Additionally, the bracket module may include at least one compression groove formed on a side that is in close contact with the blocking portion.

At this time, the blocking part is made of a sponge-based material or porous sound-absorbing material having its own elasticity and restoring force, and a part of the blocking part can be pushed into the compression groove by the pressure of the bracket module during the process of combining the second frame to the first frame.

Additionally, the above-mentioned blocking member may be made of an anti-reflective color to absorb ultraviolet rays.

At this time, the blocking member may include a waterproof layer performing a waterproof function and a buffer layer performing a sound-absorbing and vibration-absorbing function, and may be formed in a structure in which they are mutually laminated.

In addition, the blocking unit further includes a sensing layer that changes color according to pH sensitivity or oxidation reaction, and the replacement time of the blocking unit can be determined based on whether the sensing layer changes color.

At this time, the blocking portion has a wider area than the area of the bracket module, but includes a pattern groove having a shape corresponding to the shape of one end surface of the second frame, and in the process of combining the second frame to the first frame, one end surface of the second frame can be inserted into the pattern groove to reinforce airtightness.

The curtain wall device including the joint sealing structure of the present invention for solving the above-described problem has the advantage of providing a blocking portion at the joint portion of the first frame and the second frame forming the curtain wall, thereby achieving complete sealing and reinforcing watertightness, insulation, and earthquake resistance, and enabling visual confirmation of deterioration of the blocking portion, thereby easily determining the timing of replacement of the blocking portion, i.e., maintenance of the curtain wall device.

In addition, even if a sliding window frame is applied to a curtain wall device, there is an advantage in that the joint between the sliding window frame and the curtain wall structure can be completely sealed, thereby forming a structure that reinforces watertightness, airtightness, insulation, and earthquake resistance.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, preferred embodiments of the present invention, which can specifically realize the objectives of the present invention, will be described with reference to the attached drawings. In describing the present embodiments, identical names and symbols will be used for identical components, and additional explanations thereof will be omitted.

The present invention relates to a curtain wall device including a joint sealing structure that provides high-density sealing at the joint where a head member (meaning a vertical member, a first frame) and a transom (meaning a horizontal member, a second frame) forming a curtain wall are joined, thereby reinforcing watertightness, insulation, and earthquake resistance.

According to one embodiment of the present invention, the curtain wall device may be configured to have a structure including a plurality of first frames (100) having a predetermined length and spaced apart from each other while being vertical to the ground as shown in FIG. 1, a plurality of second frames (200) which may be provided between the plurality of first frames (100) and have both ends joined to each of the first frames (100) so as to be horizontal to the ground, a fixing member (300) which may be positioned at both inner ends of the second frames (200) and which allows the second frames (200) to be joined and fixed to the first frames (100), and a blocking member (400) which is attached between the first frame (100) and the second frame (200) and whose attachment position is fixed by the fixing member (300).

At this time, the blocking member (400) seals the joint portion (meaning the joint portion where the first frame and the second frame are mutually connected) of the first frame (100) and the second frame (200), thereby effectively blocking moisture penetration, thermal bridge phenomenon, noise, and vibration to the joint portion, thereby enhancing the watertightness, insulation, noise reduction, and earthquake resistance of the curtain wall device.

The above blocking part (400) may be simply placed on the joint portion where the second frame (200) is joined on one side of the first frame (100), and then may be fixed to the joint portion by the fixing part (300) during the process of joining the first frame (100) and the second frame (200), but is not limited thereto. In order to facilitate manufacturing and prevent the blocking part (400) from being moved indiscriminately during the process of joining the first frame (100) and the second frame (200), before joining the second frame (200) to the first frame (100), the second frame (200) may be pre-attached to the position where the second frame (200) should be joined, i.e., the preset joint portion, on the first frame (100), and then fixed to the joint portion by the fixing part (300), thereby preventing the first frame (100) and the second frame (200) from being joined by the blocking part (400). It is desirable to ensure that the sealing structure of the joint of the second frame (200) is stably joined.

To this end, an adhesive layer may be formed on the side of the blocking part (400) that is in close contact with the first frame (100), but is not limited thereto, and by applying adhesive to the relevant area, the blocking part (400) may be attached to a preset position of the first frame (100).

According to one embodiment of the present invention, the fixing member (300) that allows the second frame (200), which is a horizontal member, to be fixedly coupled to one side of the first frame (100), which is a vertical member, in the curtain wall device may include a bracket module (310) that is provided in close contact with the other side of the blocking member (400) that is in close contact with the position where the second frame (200) is coupled to the first frame (100), and has both ends bent and inserted into the inside of the second frame (200), and a coupling unit (320) that is penetrated and fastened to the bracket module (310) so that the second frame (200) is fixedly coupled to the first frame (100).

At this time, the coupling unit (320) may be configured with a bolt and nut that can be fastened and fixed to each of the first frame (100) and the second frame (200) by penetrating the bracket module (310), but is not limited thereto, and may be configured with a screw or fastening pin, and in some cases, it should be noted that the bracket module (310) may be configured to be welded to each of the first frame (100) and the second frame (200).

The curtain wall device according to the present invention having a structure like this can be manufactured through the steps of providing the first frame (100) as a vertical member, attaching the blocking member (400) to one side of the first frame (100), more specifically, to the position where the second frame (200) as a horizontal member is coupled to the first frame (100), and then, coupling and fixing the second frame (200) to the first frame (100) through the fixing member (300). The coupling process of the curtain wall device like this can be more easily understood with reference to FIG. 2.

According to one embodiment of the present invention, in the process of combining the second frame (200) to the first frame (100), the bracket module (310) that is in close contact with the blocking part (400) may include at least one compression groove (311) formed internally on the side that is in close contact with the blocking part (400).

In addition, the blocking member (400) may be made of a sponge-based material or porous sound-absorbing material having its own elasticity and restoring force, so that the second frame (200) is not damaged even when the bracket module (310) is pressed during the process of being joined to the first frame (100), and even if the first frame (100) and the second frame (200) contract or expand according to temperature change (meaning the difference in thermal expansion rates of the first and second frames made of metal), complete sealing can be achieved for the joining portion of the first frame (100) and the second frame (200).

At this time, the blocking part (400) having its own elasticity and restoring force is pushed at least partially into the compression groove (311) formed in the bracket module (310) that presses the blocking part (400) in the process of the second frame (200) being coupled to the first frame (100), so that bidirectional compression can be performed on the inner surface of the compression groove (311) by elasticity and restoring force.

For example, when a part of the blocking part (400) is pushed into the compression groove (311) formed in the bracket module (310), in order for the blocking part (400) to move up and down or left and right between the first frame (100) and the second frame (200), the frictional force generated by the inner surface of the compression groove (311) and the elasticity and restoring force of the blocking part (400) must be overcome, and this generates a considerable shear resistance, thereby forming a maximized pulling resistance compared to simple face-to-face contact, so that not only the detachment of the blocking part (400), but also the detachment or pushing of the first frame (100) and the second frame (200) due to external vibration, thermal expansion, moisture, etc. can be suppressed, and thereby long-term sealing and fixing force can be maintained.

In addition, by the combined action of the blocking portion (400) and the compression groove (311) as described above, fixation and sealing properties can be satisfied simultaneously without the need to apply a separate fluid material such as silicone to the joint portion of the first frame (100) and the second frame (200), thereby ensuring the effects of simplifying construction and reducing manufacturing costs.

The connection of the first frame (100) and the second frame (200) by the above-described fixing member (300), and the linkage between the blocking member (400) and the compression groove (311) can be more easily understood with reference to FIG. 3.

According to one embodiment of the present invention, the blocking member (400) is preferably made of a black or gray anti-reflective color that absorbs ultraviolet rays in order to maximize the insulation performance of the curtain wall device.

In addition, it is preferable that the blocking part (400) be formed of a layered structure including a waterproof layer (410) that performs a waterproof function and a buffer layer (420) that performs a sound absorption and vibration buffering function, as shown in FIGS. 4 and 5, so that each role can be faithfully performed.

As described above, the waterproof layer (410) and the buffer layer (420) are preferably made of a material having elasticity and resilience, but having different densities, so that the thermal conductivity is gradually reduced and the insulation performance is maximized.

In addition, the above blocking part (400) may further include a detection layer (430) that allows for intuitive inspection of aging or functional deterioration of the blocking part (400) after construction by discoloration according to pH sensitivity or oxidation reaction, and by determining the replacement time of the blocking part (400) according to whether the detection layer (430) discolors, maintenance of the curtain wall device may be smoothly performed.

The above sensing layer (430) may be provided on the side of the blocking part (400) where the second frame (200) is in close contact, but it is preferable to form it along the circumference of one side of the blocking part (400) so that it is exposed to the outside of the second frame (200) that is in close contact with the blocking part (400) rather than being formed on the entire area of the blocking part (400).

For example, the sensing layer (430) may be provided in the shape of a frame having a certain area along the circumference of the side where the second frame (200) is in close contact with the blocking part (400), and may include at least one of a pH-sensitive dye such as bromothymol blue, methyl orange, phenolphthalein, a polymer-dye complex that reacts to oxidation, and a heat-responsive inorganic pigment or a thermochromic pigment, thereby detecting a section that is overheated by solar heat collection through discoloration that occurs when moisture or water leaks, or when long-term exposure to ultraviolet rays, oxygen, ozone, etc., or when a temperature exceeds a certain level continues, and intuitively determining the time for replacement and maintenance of the blocking part (400).

In addition, the blocking portion (400) may have an area larger than that of the bracket module (310), but may include a pattern groove (440) formed internally in a shape corresponding to the shape of one end surface of the second frame (200).

The above pattern home (440) allows one side of the second frame (200) that is in close contact with one side of the blocking part (400) to be inserted into the inside of the blocking part (400) during the process of connecting the second frame (200) to the first frame (100), thereby increasing the mechanical fastening force between the blocking part (400) and the second frame (200), and also enhancing airtightness, thereby enabling the sealing between the first frame (100) and the second frame (200) to be more perfect.

In addition, as shown in Fig. 6, a window for indoor ventilation can be combined and applied to the curtain wall device according to the present invention, and such a window can be used even in a narrow space because it does not take up space, and can be formed as a sliding window structure that is easy to open and close.

For example, by additionally providing a sliding window frame (500) to the first frame (100) and second frame (200) forming the curtain wall, a sliding window can be formed in a certain portion of the entire curtain wall device.

At this time, the sliding window frame (500) provided in the first frame (100) and the second frame (200) that are combined to form a curtain wall structure may be provided in a structure inserted into a certain portion of the first frame (100) and the second frame (200) as shown in Fig. 7 (a), but is not limited thereto, and it should be noted that it may be formed in a structure integrally formed in the first frame (100) and the second frame (200) as shown in Fig. 7 (b).

In this way, when the first frame (100) and the second frame (200) are provided with the sliding window frame (500), it is preferable to provide a sealing portion (400a) to seal the joints of the sliding window frame (500) and the first frame (100) and the second frame (200).

The sealing portion (400a) can be applied to both the cross-sectional joint portion of the window frame (500) and the first frame (100) and the second frame (200) and the longitudinal joint portion of the window frame (500) and the first frame (100) and the second frame (200), and can be provided inside the window frame (500) to reinforce the watertightness, insulation, and earthquake resistance of the joint portion between each frame. It is preferable that the configuration be made of a multi-stage structure of heterogeneous materials having the same elasticity and restoring force as the blocking portion (400) described above, but having different densities therebetween, so that the watertightness, cushioning, insulation, and earthquake resistance performance can be maximized.

As described above, preferred embodiments of the present invention have been described. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms, in addition to the embodiments described above, without departing from the spirit or scope thereof. Therefore, the above-described embodiments should be considered illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
