Description

Technology Field

[0001] The present invention relates to a bracket device for assembling a curtain wall frame for stably connecting a vertical frame and a horizontal frame, and more specifically, to a bracket device for assembling a curtain wall frame that improves the load-bearing capacity of the frame connection part through a flange structure and a reinforcing rib structure inserted inside the horizontal frame, and improves the structural stability of the frame connection by increasing the pull-out resistance through a multi-fastening structure of the connecting piece. Background Technology

[0003] Generally, a curtain wall structure applied to the exterior walls of a building is an exterior system that does not directly support the building's load. It consists of a structure in which vertical frames arranged in the vertical direction and horizontal frames arranged in the horizontal direction are combined to form a grid structure, with glass panels or exterior panels installed between them.

[0004] In such curtain wall structures, the connection structure between the vertical and horizontal frames has a significant impact on the structural stability and construction quality of the entire exterior system.

[0005] In particular, for high-rise buildings, strong wind pressure, vibration, and repetitive loads are applied, so the rigidity and stability of the frame connections are very important.

[0006] In typical curtain wall frame structures, separate connecting brackets or members are used to connect vertical and horizontal frames, and these connecting members are installed by being fixed to the frame primarily through fastening components such as screws or bolts.

[0007] However, conventional connection structures have limited fastening points, which prevents them from sufficiently distributing the load generated at the frame connection point. Additionally, there were issues where the fastening part detached due to external forces or minute play occurred at the frame connection point.

[0008] In addition, conventional frame connection structures lack sufficient structural rigidity to support the horizontal frame, which may lead to sagging or rotational deformation of the frame during long-term use; such deformation can impede the precise installation of the exterior panels and affect the appearance quality.

[0009] In addition, if a structure to effectively block moisture entering from the outside around the frame connection points is not sufficiently considered, moisture may enter through the joints, potentially leading to a decrease in the durability of the curtain wall system.

[0010] Therefore, there is a need to develop a new type of bracket device for assembling curtain wall frames that can connect vertical and horizontal frames more stably, improve structural rigidity, increase the pull-out resistance of the fastening part, and simultaneously improve constructability and watertightness.

[0012] Republic of Korea Registered Patent No. 10-1697741 The problem to be solved

[0013] The present invention has been devised in consideration of the above-mentioned problems, and the first objective of the present invention is to provide a bracket device for assembling a curtain wall frame that secures cross-sectional rigidity of the frame connection part, suppresses deformation of the joint part, and maintains structural integrity even under repeated loading conditions through an upper flange and a lower flange inserted inside the horizontal frame and a reinforcing rib having a closed cross-section structure disposed between them.

[0015] The second objective of the present invention is to provide a bracket device for assembling a curtain wall frame that can improve the structural stability of the frame connection part by securing a load distribution effect through a structure in which the connecting piece penetrates the upper flange and reinforcing rib multiple times to multiplely multiply the load transfer path, and by improving the resistance performance against pull-out load and shear load. means of solving the problem

[0017] According to the features for achieving the above-mentioned purpose, the first invention relates to a bracket device for assembling a curtain wall frame for stably connecting a vertical frame and a horizontal frame, and for this purpose comprises: a base portion fixed in close contact with the side wall of the vertical frame; and an upper flange and a lower flange that extend horizontally from each side of the base portion and are inserted into the internal space of the horizontal frame to support the horizontal frame. The structure comprises a reinforcing rib formed integrally with the base portion between the upper flange and the lower flange, wherein a connecting piece fastened from the exterior side to the interior side of the horizontal frame penetrates the outer wall of the horizontal frame and continuously penetrates the upper flange and the reinforcing rib located inside the horizontal frame to form a structure of multiple fastening, thereby distributing the load acting on the connecting piece to multiple fastening points and improving the resistance to pull-out load and shear load of the fastening portion, wherein the reinforcing rib is integrally connected with the base portion in the inner space between the upper flange and the lower flange, and is characterized by being formed as a closed cross-section structure in the shape of a square box containing a hollow interior.

[0021] The third invention is characterized in that, in the first invention, the reinforcing rib includes vertical walls on both sides in the shape of a square box, and the connecting piece is penetrated and fastened at multiple points through the vertical walls to form multiple fastening points, thereby increasing resistance to pull-out loads acting on the connecting piece and distributing the shear load acting on the fastening part to multiple fastening surfaces to reinforce shear resistance performance.

[0023] The fourth invention is characterized in that, in the first invention, the upper flange has a filling space formed concavely so that silicone is filled into the joint between the vertical frame and the horizontal frame.

[0025] The fifth invention is characterized in that, in the first invention, the upper flange and the lower flange are formed asymmetrically to have different extension lengths. Effects of the invention

[0027] The bracket device for assembling a curtain wall frame according to the present invention has the effect of forming a connection structure between a vertical frame and a horizontal frame more stably through a structure comprising a base portion fixed in close contact with the side wall of a vertical frame, an upper flange and a lower flange extending horizontally from both sides of the base portion and inserted into the internal space of a horizontal frame, and a reinforcing rib formed between the upper flange and the lower flange.

[0028] In addition, through a structure in which the upper and lower flanges respectively support the upper and lower surfaces of the horizontal frame, the load acting on the horizontal frame can be stably transferred to the vertical frame through the base, thereby improving the structural stability and load-bearing capacity of the frame connection.

[0029] In addition, the reinforcing rib is formed as a closed-section structure in the shape of a hollow square box, thereby structurally improving bending stiffness and torsional stiffness due to the increase in the second moment of area, and accordingly, local deformation and torsional deformation of the joint can be effectively suppressed against wind load, self-weight, and repetitive loads acting on the horizontal frame.

[0030] In particular, the closed-section structure has superior cross-sectional stiffness retention capabilities compared to the open-section structure, which effectively allows for the stable maintenance of structural integrity at the frame connections even under long-term repetitive loading conditions.

[0031] In addition, the above-mentioned connecting piece forms a structure that penetrates the outer wall of the horizontal frame and is multiplely fastened to the vertical walls of the upper flange and the closed-section reinforcing rib, thereby dispersing the load transfer path into multiple paths to alleviate local stress concentration and improve the pull-out resistance of the fastening part. Furthermore, it has the effect of reinforcing shear resistance performance against shear loads acting on the fastening part through the multiple fastening surfaces.

[0032] In addition, when the joint piece is fastened by the aforementioned compression-inducing protrusion line, a structure is formed in which the base part undergoes elastic deformation and is compressed and adheres closely to the outer surface of the vertical frame. This effectively eliminates minute gaps that may occur at the frame joint and reduces minute vibrations caused by external forces or repetitive vibrations, thereby maintaining the durability and fastening stability of the joint even in long-term usage environments.

[0041] Hereinafter, a bracket device for assembling a curtain wall frame according to the present invention will be described in detail together with the attached drawings.

[0043] FIG. 1 is a perspective view showing the combined state of a vertical frame and a horizontal frame, FIG. 2 is a perspective view showing a bracket device for assembling a curtain wall frame according to the present invention attached to a vertical frame, FIG. 3 is a perspective view showing a bracket device for assembling a curtain wall frame according to the present invention extracted from FIG. 2, FIG. 4 is a cross-sectional view of FIG. 1 to which the present invention is applied, and FIG. 5 is an enlarged cross-sectional view showing a base part fastened to a vertical frame in FIG. 4.

[0045] As illustrated in FIGS. 1 to 5, the present invention relates to a bracket device (100) for assembling a curtain wall frame that improves the load-bearing capacity of the frame connection part through a flange structure and a reinforcing rib structure inserted inside the horizontal frame, and improves the structural stability of the frame connection by increasing the pull-out resistance through a multi-fastening structure of the connecting piece.

[0047] The present invention relates to a bracket device (100) for assembling a curtain wall frame that can stably connect a vertical frame (200) and a horizontal frame (300) while improving structural rigidity and constructability, and may be composed of a base part (10), an upper flange (20), a lower flange (30), and a reinforcing rib (40).

[0049] As shown in FIG. 2, the base portion (10) is a component that supports the bracket device (100) for assembling a curtain wall frame of the present invention by being combined with a vertical frame (200), and is structured to be placed in close contact with the side wall of the vertical frame (200) and fixed by a connecting piece (P).

[0050] The base portion (10) is formed in a flat plate shape and is positioned to be in close contact with the outer surface of the vertical frame (200) to support the connecting load between the vertical frame (200) and the horizontal frame (300).

[0051] In addition, a plurality of position indicator lines (12) indicating the fastening position may be further formed on the surface of the base part (10) so that a worker can easily identify the position where the connecting piece (P) is fastened.

[0052] In addition, as shown in Fig. 3(b), a plurality of compression-inducing protrusion lines (11) that protrude in the direction of the vertical frame (200) may be further formed on the other side of the base part (10).

[0053] As shown in FIG. 5, the above compression guide protrusion line (11) functions to form a space (13) of a certain distance between the side wall of the vertical frame (200) and the base part (10), and when the connecting piece (P) is fastened in the direction of the vertical frame (200), the base part (10) can be elastically deformed with respect to the compression guide protrusion line (11) and act to be compressed and adhered to the outer surface of the vertical frame (200).

[0054] That is, the above-mentioned compression-inducing protrusion line (11) induces the base part (10) to undergo elastic deformation during the process of the coupling piece (P) being fastened, thereby functioning to maintain a continuous compression-contact state with respect to the outer surface of the vertical frame (200).

[0055] This elastic contact structure can suppress the base part (10) from shaking or moving in the left and right directions on the side wall of the vertical frame (200) and provide the effect of reducing minute gaps that may occur when joining the frame.

[0056] In addition, the elastic adhesive structure maintains the adhesive force between the vertical frame (200) and the base part (10) even after the connecting piece (P) is fastened, thereby reducing minute vibrations that may occur due to external force and suppressing the loosening of the connecting part even during long-term use, which can provide the effect of improving durability.

[0058] As shown in FIGS. 3 and 4, the upper flange (20) and the lower flange (30) are structured to extend horizontally on both sides of the base part (10).

[0059] These upper flange (20) and lower flange (30) are formed spaced apart from each other so that a horizontal frame (300) can be inserted between them, and thus can function to support the horizontal frame (300).

[0060] In addition, the upper flange (20) and the lower flange (30) can be formed in an asymmetrical structure to have different extension lengths.

[0061] That is, either the upper flange (20) or the lower flange (30) can be configured to be formed relatively longer, and accordingly, when inserting the horizontal frame (300) into the upper flange (20) and the lower flange (30), the horizontal frame (300) can be inserted in a horizontal direction after entering in an inclined state due to the shorter flange.

[0062] With this structure, the insertion and joining of the horizontal frame (300) can be made easier, thereby improving construction efficiency at the site.

[0063] Meanwhile, the upper flange (20) may have a filling space (21) formed therein so that silicone (S) can be filled to seal the joint between the vertical frame (200) and the horizontal frame (300).

[0064] The silicone (S) filled in the above-mentioned filling space (21) is positioned inside the joint between the horizontal frame (300) and the vertical frame (200) to avoid external exposure and also prevent moisture from entering from the outside, thereby improving watertightness.

[0066] As shown in FIG. 3, the reinforcing rib (40) is a structure formed between the upper flange (20) and the lower flange (30).

[0067] The reinforcing rib (40) is integrally connected to the base portion (10) between the upper flange (20) and the lower flange (30), and is formed as a closed-section structure in the shape of a square box containing a hollow interior.

[0068] The reinforcing rib (40) of this closed section structure has a structural feature that increases the second moment of area compared to an open rib structure, and accordingly, the bending stiffness and torsional stiffness of the bracket device (100) can be improved simultaneously.

[0069] In particular, since the closed cross-section structure has the characteristic of distributing stress across the entire cross-section when an external load is applied, it can suppress local buckling or joint deformation that may occur due to the load transmitted from the horizontal frame (300).

[0070] In addition, even when subjected to repetitive wind or vibration loads, the closed-section structure can minimize deformation of the cross-sectional shape, thereby contributing to maintaining the structural integrity of the frame connections over the long term.

[0072] As shown in FIG. 4, for the aesthetics of the interior, the connecting piece (P) is fastened from the exterior side of the horizontal frame (300) toward the interior side, and after penetrating the outer wall of the horizontal frame (300), it first penetrates the upper flange (20), and then has a multi-fastening structure in which it continuously penetrates and fastens the vertical wall (41) constituting the reinforcing rib (40) of the closed cross-section structure at multiple points.

[0073] In the above, the reinforcing rib (40) may include a vertical wall (41) forming a square box shape, and the connecting piece (P) is configured to form multiple screw fastening points by each of the vertical walls (41) to increase the pull resistance.

[0074] In the above, the indoor end of the horizontal frame (300) tends to rotate downward due to the load, but as the connecting piece (P) is fastened deep into the interior of the reinforcing rib (40), the reinforcing rib (40) acts as an internal support axis (Anchor Core) rather than a simple support part, thereby implementing a rotational deformation suppression mechanism.

[0075] Accordingly, rotational deformation such as the horizontal frame (300) shaking up and down or the end facing the interior sagging due to external load or the frame's own weight is effectively suppressed, thereby ensuring precise construction quality and structural stability simultaneously.

[0076] In addition, the upper flange (20) acts as a primary support surface for the connecting piece (P) to form an initial fastening force, and the vertical walls (41) on both sides of the closed cross-section reinforcing rib (40) provide additional fastening resistance surfaces for the connecting piece (P), thereby simultaneously forming multiple shear surfaces and friction resistance surfaces when the connecting piece (P) attempts to move in the pulling direction.

[0077] Here, when a pull-out load is applied, the connecting piece (P) must simultaneously resist multiple fastening points, unlike a single fastening structure, so the pull-out resistance path is multiplexed, and the pull-out resistance performance can be structurally improved.

[0078] In addition, when a shear load is applied, the load acting on the horizontal frame (300) is transmitted through the connecting piece (P), and at this time, multiple fastening points share the shear force, so the shear stress acting on each fastening part is distributed and the shear resistance performance can be increased.

[0079] As a result, this enables the provision of safety that maintains the structural integrity of the frame connections even in the harsh external environment of high-rise buildings.

[0081] The embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; therefore, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.
