Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall installation parts, in particular to a building curtain wall dry hanging structure. Background Art

[0002] The curtain wall is the exterior wall of a building. It does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It has a certain displacement ability relative to the main structure or a certain deformation ability of itself, and does not bear the effects of the main structure. It is an exterior protective structure or decorative structure of the building.

[0003] Most of the existing curtain wall installation methods are to install keels (including horizontal bars and vertical bars) on the outer wall of the building, then install a hanger group on the installation keel, and then open a hanging groove on the side of the curtain wall panel, insert the hanger group into the hanging groove, and hang the curtain wall panel on the installation keel, for example: Chinese patent CN221168291U. However, the hanger group is formed by assembling multiple parts, which brings great inconvenience to the construction and also affects the construction efficiency.

[0004] The Chinese patent application with the publication number CN118375250A discloses a curtain wall system, in which the hanging parts used are single structural parts, which simplifies the hanging parts installation process. However, the curtain wall panels of the curtain wall system need to be processed with special shapes, which increases the processing burden; and when installing the curtain wall panels, the curtain wall panels need to be squeezed first, so that the top plug-in part is inserted inward and upward into a hanging part located above it, until the bottom plug-in part of the curtain wall panel is higher than the upper notch of a hanging part located at the bottom, and then the curtain wall panel is moved downward so that the bottom plug-in part is inserted downward into the upper notch of another hanging part located below it, so that the curtain wall panel is installed between the upper and lower adjacent hanging parts, and the curtain wall panel installation method is relatively complicated; in addition, the matching degree requirements for the size of the hanging parts and the curtain wall panels and the installation distance between the adjacent hanging parts are also high, which increases the processing difficulty; in addition, in order to provide space for the installation of the top and bottom plug-in parts of the curtain wall panels, a large gap will be left between the upper and lower adjacent curtain wall panels, which brings inconvenience to the sealing between the board seams.

[0010] The building curtain wall dry hanging structure of the utility model is not limited to the shape of the curtain wall panel and has a wide range of application for the curtain wall panel. Moreover, by aligning the slide groove of the hanger on the curtain wall panel with the upper edge of the bracket laterally and pushing the curtain wall panel and the hanger toward the bracket side laterally so that the upper edge of the bracket is horizontally inserted into the slide groove, the assembly cooperation between the bracket and the hanger can be achieved, and the assembly stability is improved by the bracket abutment portion. The curtain wall panel is installed on the crossbeam, which is easier and more convenient to install and to remove. Moreover, the gap between adjacent curtain wall panels is not affected by the assembly process and can be as small as possible, which is conducive to subsequent sealing.

[0011] Furthermore, a screw hole is opened in the middle of the main body of the hanging component, and a locking screw passes through the screw hole and is locked into the curtain wall panel to achieve the fixation between the hanging component and the curtain wall panel.

[0012] Furthermore, the bracket is an L-shaped structure consisting of a horizontal arm and a vertical arm, the vertical arm is arranged upward, and the vertical arm is located on the curtain wall panel side of the horizontal arm; the upper edge of the vertical arm is inserted into the slide groove portion of the hanger; the horizontal arm of the bracket is locked and fixed to the crossbeam by bolt and nut assembly parts, which is easy to assemble.

The second guide rail is arranged in a direction parallel to the cross beam. A second guide groove is formed in the bracket contact part, and the second guide rail cooperates with the second guide groove. The arrangement of the bracket contact part of the main body of the hanging part can disperse the pressure received by the upper edge of the bracket, and avoid bending and deformation of the vertical arm of the bracket when hanging a relatively heavy curtain wall panel.

[0015] Further, a foam strip and sealant are filled in the gap between two adjacent curtain wall panels for sealing.

[0016] The hanging part is preferably of an integrally formed structure. Description of the Drawings

[0017] Figure 1 is a top view structure diagram of the dry hanging structure of the building curtain wall of the present invention, in which the main structure and the curtain wall panel are both sectional structure diagrams;

[0018] Figure 2 is a sectional structure schematic diagram of the dry hanging structure of the building curtain wall of the present invention along Figure 1 the A-A line in Detailed Embodiment

[0019] The following describes in detail the preferred embodiments of the dry hanging structure of the building curtain wall of the present invention with reference to the drawings:

[0020] Combining Figure 1 and Figure 2 , a dry hanging structure for a building curtain wall includes a keel frame 20 installed on a main structure 10 and a curtain wall panel 30 installed on a side of the keel frame 20 facing away from the main structure 10;

[0021] The keel frame 20 includes upright columns 21 and cross beams 22 arranged vertically and horizontally, and a bracket 40 is installed on the cross beam 22;

[0022] A hanging part 50 for hanging and cooperating with the bracket 40 is fixedly installed on the back side of the curtain wall panel 30;

[0023] The hanging part 50 includes a C-shaped main body 51, and the middle part of the back surface of the main body 51 is tightly attached and fixedly connected to the back surface of the curtain wall panel 30; a chute part 52 is connected and arranged at the upper end of the main body 51; the chute part 52 has a chute 521 extending in a direction parallel to the cross beam 22; the cross section of the chute 521 is U-shaped with an opening facing downwards for the upper edge of the bracket 40 to be inserted therein; a bracket contact part 53 capable of contacting the surface of the bracket 40 facing the curtain wall panel 30 is connected to the lower end of the main body 51.

[0024] The dry-hanging structure of the building curtain wall of the present utility model has no limitation on the shape of the curtain wall panel and has a wide range of applicability for the curtain wall panel. Moreover, by horizontally inserting the upper edge of the bracket 40 into the sliding groove 521, the assembly cooperation between the bracket 40 and the hanging member 50 can be achieved, and the assembly stability is improved through the bracket abutting portion 53. The curtain wall panel 30 is installed on the cross beam 22, which is easier and more convenient to install and also convenient to remove. Additionally, the gap between adjacent curtain wall panels 30 is not affected by the assembly process and can be minimized, which is beneficial for subsequent sealing.

[0025] Further, as Figure 2 shown, a screw hole is provided in the middle of the main body 51 of the hanging member 50, and the locking screw 60 passes through the screw hole and is locked into the curtain wall panel 30 to achieve the fixation between the hanging member 50 and the curtain wall panel 30. Of course, the fixation method between the hanging member 50 and the curtain wall panel 30 can be but is not limited to being locked and fixed by the locking screw 60, and it can also be fixed by other methods (such as bonding).

[0026] Further, as Figure 2 shown, the bracket 40 is an L-shaped structure composed of a horizontal arm 42 and a vertical arm 41. The vertical arm 41 is arranged upwards and is located on the curtain wall panel 30 side of the horizontal arm 42. The upper edge of the vertical arm 41 is inserted into the sliding groove portion 52 of the hanging member 50. The horizontal arm 42 of the bracket 40 is locked and fixed to the cross beam 22 through a bolt and nut assembly 70, which is convenient for assembly.

[0027] Further, as Figure 2 shown, a first guide rail 80 is arranged on the side surface of the upper edge of the bracket 40 in a direction parallel to the cross beam 22, and a first guide groove 90 is provided on the inner side surface of the sliding groove 521 of the hanging member 50. The first guide rail 80 and the first guide groove 90 cooperate with each other. Preferably, as Figure 2 shown, there are two first guide rails 80, which are respectively arranged on the two side surfaces of the upper edge of the bracket 40; there are two first guide grooves 90, which are arranged in one-to-one correspondence with the first guide rails 80. Of course, the dry-hanging structure of the building curtain wall of the present utility model may not be provided with the first guide rail 80 and the first guide groove 90. In this case, by adjusting the gap between the upper edge of the bracket 40 and the sliding groove 521, the upper edge of the bracket 40 is limited in the sliding groove 521. However, such a fit is not firm, and the curtain wall panel 30 is prone to shaking when the dimensional matching degree is not high.

[0028] Further, a second guide rail 100 is provided at a position where the bracket contact portion 53 of the bracket 40 abuts against the bracket of the hanging member 50. The second guide rail 100 is arranged in a direction parallel to the cross beam (the second guide rail 100 is parallel to the first guide rail 80). A second guide groove 110 is formed in the bracket contact portion 53, and the second guide rail 100 and the second guide groove 110 cooperate with each other. The arrangement of the bracket abutting portion 53 of the hanging member 50 and the cooperation of the second guide rail 100 and the second guide groove 110 can disperse the pressure received by the upper edge of the bracket 40, and prevent the vertical arm 41 of the bracket 40 from being bent and deformed when hanging a relatively heavy curtain wall panel 30. Of course, the dry hanging structure of the building curtain wall of the present invention may not be provided with the second guide rail 100 and the second guide groove 110. In this case, the bracket abutting portion 53 directly abuts against the vertical arm 41 of the bracket 40.

[0029] Further, a foam strip 120 and a sealant 130 are filled in the gap between two adjacent curtain wall panels 30 for sealing.

[0030] In the specific implementation process, the hanging member 50 is preferably an integrally formed structure.

[0031] A rubber gasket 140 can be clamped between the main body 51 of the hanging member 50 and the curtain wall panel 30. A through hole for the locking screw 60 to pass through is formed in the rubber gasket 140.

[0032] For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present invention.
