Description

Technical Field

[0001] The invention belongs to the technical field of building engineering, and relates to a building facade curtain wall structure, in particular to an adjustable full-hidden point support frame curtain wall system. Background Art

[0002] With the diversification of architectural shapes, the structural form of glass curtain walls is becoming more and more complex. The facade of the curtain wall uses broken lines and curved surfaces to achieve the desired appearance. At present, the structural design of the curtain wall corners is mostly fixed, that is, the component profiles connected to the curtain wall are customized into specific fixed structures according to different angles, so as to achieve changes at different angles. In this way, it is necessary to develop various aluminum alloy molds. Although the structure is simple, due to poor versatility, there are many types of profile molds, high cost, long cycle, low efficiency, and poor processing and installation precision.

[0003] Under the premise of current regulations, in order to meet the requirements of simple and transparent building facade glass, a semi-hidden frame structure is usually adopted. This structure has the following shortcomings: (1) It is inevitable to have horizontal or vertical aluminum alloy pressure plates and buckle covers; (2) In the case of multiple angle changes, the matching pressure plates and buckle covers will be added, and the facade effect is not good.

[0004] In addition, the patent CN214696292U discloses an adjustable angle hidden frame curtain wall system, which includes an aluminum alloy sub-frame 1, a glass panel is bonded to the aluminum alloy sub-frame 1 by silicone structural adhesive, and a notch suitable for assembling angle steel sheets is provided on the aluminum alloy sub-frame 1; the aluminum alloy sub-frame 1 and the aluminum alloy sub-frame 2 are connected by a hinge shaft. Although it discloses a technical solution for realizing a hidden frame curtain wall with different angles of 170° to 190° by a glass sub-frame with a hinge shaft. However, it adopts an open-cavity rotating bite design composed of a hinge shaft and a notch, and the adjustment angle range is relatively small, which cannot meet the application scenario of large-angle glass panel large-angle adjustment; and the existing open-cavity rotating bite design cannot effectively control the problem of over-rotation of the profile angle, which is not conducive to on-site construction, and is also prone to stress concentration between the structural adhesive and the glass due to angle rotation, causing the structural adhesive to be unstable and damaged, and there are certain safety hazards.

[0060] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0061] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0062] In some embodiments, Figure 1 , Figure 3 , Figure 6 , Figure 8 and Fig.10 As shown, in view of the limitations of the existing semi-hidden frame curtain wall structure, an adjustable fully hidden point support frame curtain wall system is provided, which mainly includes a column 100, a glass unit 200, a plurality of groups of inner hidden frame fasteners 300 and a plurality of groups of outer pressure plate fasteners 400. The connection between two adjacent glass units 200 is adjustably mounted on the column 100 on the inner side as the curtain wall keel through a plurality of groups of inner hidden frame fasteners 300 and a plurality of groups of outer pressure plate fasteners 400.

[0063] Several groups of inner hidden frame fasteners 300 are respectively installed at the connection of two adjacent glass units 200 at equal distances, and are respectively used to install and fix different positions of the glass units 200. Specifically, the inner sides of two adjacent glass units 200 are respectively connected to the column 100 through the first fastener 303 and the second fastener 304 at both ends of each inner hidden frame fastener 300, and the connection between the first fastener 303 and the second fastener 304 is fastened to each other and arranged in a concentric circle so as to be rotatable, so as to meet the installation requirements of different glass angles.

[0064] Several groups of external pressure plate fasteners 400 are respectively installed at the connection of two adjacent glass units 200 at equal distances, and are respectively used to install and fix different positions of the glass units 200. Specifically, the outer sides of two adjacent glass units 200 are respectively connected to the column 100 through the first pressure plate 401 and the second pressure plate 402 at both ends of each external pressure plate fastener 400 via the adapter 405, and the first pressure plate 401 and the second pressure plate 402 are respectively engaged and connected with the sawtooth column 403 at the end of the adapter 405 to meet the fixing requirements of different glass angles.

[0065] In some embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.10 As shown, the outer end of the column 100 is designed as an inverted U-shaped notch 101, and several groups of the inner hidden frame fasteners 300 and several groups of the outer pressure plate fasteners 400 are installed at intervals along the length direction of the inverted U-shaped notch 101. The column 100 is a curtain wall keel made of aluminum alloy.

[0066] The two ends of the inverted U-shaped notch 101 are connected to the two adjacent glass units 200 via a sealing strip 102. The sealing strip 102 is an O-shaped sealing strip with a special structure, which is installed between the column 100 and the glass unit 200 to provide buffer protection for the glass unit 200.

[0067] In addition, in order to realize the installation and fixation of the inner hidden frame fastener 300 and the outer pressure plate fastener 400, a first clamping groove 103 is provided in the middle position of the inner end surface of the inverted U-shaped notch 101 along its length direction, which is used to insert and install the first locking bolt 301 and the second locking bolt 407 from the top notch. The first locking bolt 301 adopts an M6 stainless steel pan head machine screw.

[0068] At the same time, second card slots 104 are respectively provided on both sides of the first card slot 103 for inserting the installation card plate 406 from the top slot; and first limiting protrusions 105 are respectively provided on both ends of the slot of the first card slot 103 for limiting the installation of the sub-frame pressing block 302.

[0069] In some of the embodiments, Figure 1 , Figure 3 , Figure 6 , Figure 8 and Fig.10 As shown, two adjacent glass units 200 share a curtain wall keel column 100. In order to ensure the sealing between the two glass units 200 after installation, the two adjacent glass units 200 are sealed and connected by O-shaped sealing strips 201 and sealant 202, and the O-shaped sealing strips 201 are located at the inner side of the sealant 202, and the sealant 202 is formed by curing after applying the sealant liquid.

[0070] In some of the embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the inner hidden frame fastener 300 mainly includes a first locking bolt 301, a sub-frame pressing block 302, a first fastener 303 and a second fastener 304, and the first locking bolt 301, the sub-frame pressing block 302, the first fastener 303 and the second fastener 304 are all made of aluminum alloy.

[0071] Specifically, the inner end of the first locking bolt 301 is inserted from the top opening of the inverted U-shaped notch 101 and is snap-fitted into the first slot 103 at the outer end of the column 100, and the outer end is locked and connected to the middle part of the sub-frame pressing block 302 by a nut to fix the sub-frame pressing block 302 at a corresponding height in the inverted U-shaped notch 101.

[0072] In cooperation with the sub-frame pressing block 302, the first fastener 303 is an inverted L-shaped structure, which is two in number and arranged symmetrically on both sides, and the outer side walls of the inner ends thereof are respectively pressed and connected with the two ends of the sub-frame pressing block 302. The two ends of the sub-frame pressing block 302 are pressed against the first fastener 303 by the first locking bolt 301, so as to realize the positioning and installation of the first fastener 303.

[0073] Corresponding to the first fastener 303 , the second fastener 304 is an F-shaped structure, and there are two of them, which are arranged symmetrically. One end of the second fastener 304 is rotatably connected to the outer end of the corresponding first fastener 303 , and the other end is connected to the inner side of the glass unit 200 .

[0074] When two adjacent glass units 200 need to be installed at a certain angle, the second fastener 304 can rotate relative to the first fastener 303 at the connection between the two, thereby ensuring that the second fastener 304 is stably connected to the inner side of the glass unit 200 and adapting to the requirements of different glass angles.

[0075] It is worth noting that a support block 305 and a buffer block 306 are arranged side by side between the outer end surface of the second fastener 304 and the glass unit 200. The support block 305 is made of stainless steel, aluminum alloy or hard plastic, and is located at the outer end of the square clamp 3042, and is mainly used to support and connect the glass unit 200. The buffer block 306 is made of rubber, and is arranged at the outer end of the bottom plate 3041 and is installed in contact with the glass unit 200, so that the second fastener 304 can produce elastic deformation when relatively rotating, so as to reduce the squeezing force on the glass unit 200, thereby improving the safety of the system structure.

[0076] As a preferred embodiment thereof, Figure 1 , Figure 2 and Figure 5 As shown, the sub-frame pressing block 302 is a cover plate structure with a flat inner side and an arc outer side, i.e., a flat inner side and an arc outer side, and a through hole is provided at the central axis of the sub-frame pressing block 302 for installing the first locking bolt 301 .

[0077] In order to ensure the stability of the installation of the sub-frame pressing block 302 and avoid slipping due to left-right shaking, two first limiting bosses 3021 are arranged symmetrically and corresponding to the first limiting protrusions 105 at the middle position of the inner end surface of the sub-frame pressing block 302. The sub-frame pressing block 302 is limitedly installed between the left and right first limiting protrusions 105 by the two first limiting bosses 3021 to achieve installation positioning.

[0078] In addition, to ensure the adjustable movable connection with the first fastener 303, second limiting bosses 3022 that match the inner ends of the first fastener 303 are respectively provided at both ends of the inner end surface of the sub-frame pressing block 302. The second limiting bosses 3022 realize the point connection between the sub-frame pressing block 302 and the first fastener 303. The point connection method facilitates the left and right movement of the first fastener 303, thereby realizing the rapid adjustment of the position of the first fastener 303.

[0079] As a preferred embodiment thereof, Figure 2 and Figure 5 As shown, the first fastener 303 is an inverted L-shaped structure, with press-fit bosses 3031 provided at both ends of its inner end surface, and one end thereof is connected to a circular fastener 3033 via a Z-shaped connector 3032. The press-fit boss 3031, the Z-shaped connector 3032 and the circular fastener 3033 are integrally formed.

[0080] Correspondingly, the second fastener 304 is an F-shaped structure, which is integrally formed by a bottom plate 3041 and a square clamping block 3042. The bottom plate 3041 is a plate-like structure with one end thin and the other end thick, and the square clamping block 3042 is arranged on the inner side of the thicker end; the square clamping block 3042 is provided with a circular clamping groove 3043, and the circular clamping groove 3043 is rotatably buckled with the circular fastener 3033 on the first fastener 303.

[0081] Depend on Figure 1 , Figure 3 and Figure 6 It can be seen that the outer end of the second fastener 304 is tightly attached to the glass unit 200 on one side. When the glass unit 200 on one side is installed at a certain angle relative to the glass unit 200 on the other side, the glass unit 200 drives the second fastener 304 on the inner side to rotate synchronously during the rotation process. Because the circular groove 3043 of the second fastener 304 is connected to the circular fastener 3033 of the first fastener 303 in a concentric circle, when the second fastener 304 rotates, the circular groove 3043 at one end thereof rotates relative to the circular fastener 3033, thereby realizing the adaptive rotation adjustment of the second fastener 304.

[0082] In some of the embodiments, Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, the inner hidden frame fastener 300 mainly includes a first locking bolt 301, a sub-frame pressing block 302, a first fastener 303, a second fastener 304 and a limit clamping column 307, and the first locking bolt 301, the sub-frame pressing block 302, the first fastener 303, the second fastener 304 and the limit clamping column 307 are all made of aluminum alloy. Different from the above embodiment, the first fastener 303 and the second fastener 304 directly adopt a concentric circle buckle mode with a specific structural design. One end of the first fastener 303 is buckled with one end of the second fastener 304 through a limit clamping column 307.

[0083] Specifically, a first rotating sleeve 3034 is respectively provided at the middle of one end of the first fastener 303, and two symmetrically arranged first rotating slots 3035 are respectively provided on the inner cavity wall of the first rotating sleeve 3034 along its length direction. Correspondingly, a second rotating sleeve 3044 is provided at the top and bottom ends of one end of the second fastener 304, and two symmetrically arranged second rotating slots 3045 are respectively provided on the inner cavity wall of the second rotating sleeve 3044 along its length direction.

[0084] The position-limiting clamping column 307 is a cylindrical structure, and its circumference is provided with two position-limiting clamping blocks 3071 along its length direction, which are matched with the first rotating clamping slot 3035 and the second rotating clamping slot 3045, and are correspondingly inserted into the first rotating sleeve 3034 and the two second rotating sleeves 3044. It is worth noting that, in order to meet the angle adjustment requirements of the glass unit 200, the position-limiting clamping block 3071 is rotatable at an angle of ±20° in the first rotating clamping slot 3035 and the second rotating clamping slot 3045, and the fan size of the first rotating clamping slot 3035, the second rotating clamping slot 3045 and the fan size are designed in this way, so as to achieve a larger adjustable angle range compared with the existing notch bite design of the cavity.

[0085] When in use, first assemble and align a pair of first fasteners 303 and second fasteners 304, so that the first rotating sleeve 3034 at the end of the first fastener 303 is located between the two second rotating sleeves 3044 at the end of the second fastener 304, and are aligned up and down. Then insert the limit clamping column 307 from the top into the inner cavity of the first rotating sleeve 3034 and the second rotating sleeve 3044, and make the limit clamping block 3071 limitedly installed in the second rotating slot 3045 and the first rotating slot 3035; then use the hexagon socket machine screw to lock the limit from the top and bottom of the limit clamping column 307 respectively. Compared with the existing open-cavity slot bite design, the closed-cavity rotating mechanism design composed of the first fastener 303, the second fastener 304 and the limit clamping column 307 has a more stable profile force and a safer structural system.

[0086] In addition, in order to overcome the problem that the existing open-cavity rotating bite design cannot effectively control the over-rotation of the profile angle, is not conducive to on-site construction, and is prone to stress concentration between the structural adhesive and the glass due to angle rotation, causing safety hazards, a rotation mechanism design with controllable adjustment angle is provided. The rotation mechanism is mainly composed of a first fastener 303, a second fastener 304 and a limit clamping column 307. By controlling the width of the rotating slots on the first fastener 303 and the second fastener 304 and / or the width of the block on the limit clamping column 307, the rotation angle of the first fastener 303 relative to the second fastener 304 is controlled, thereby achieving the purpose of adapting to different glass angle installation requirements.

[0087] If necessary, the concentric axial profile formed by the limit clamp 307 and the first fastener 303 and the second fastener 304 can be set with angle limits at intervals of 5° to effectively control the over-rotation of the profile angle, which is more convenient for on-site construction and reduces the stress concentration problem between the structural adhesive and the glass due to angle rotation, making the structural adhesive more stably stressed and improving safety.

[0088] Specifically, Fig.15As shown, the arc of the first rotating slot 3035 on the first fastener 303 and the second rotating slot 3045 on the second fastener 304 can be set to 45°, and the width of the upper limit block 3071 on the limit column 307 can be set to 35°. The limit block 3071 can be adjusted to an angle of ±10° in the rotating slot.

[0089] Another example Fig.16 As shown, the arc of the first rotating slot 3035 on the first fastener 303 and the second rotating slot 3045 on the second fastener 304 is set to 50°, and the width of the upper limit block 3071 on the limit column 307 is set to 30°. The limit block 3071 can be adjusted to an angle of ±00° in the rotating slot.

[0090] In some of the embodiments, Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the outer pressure plate fastener 400 mainly includes a first pressure plate 401, a second pressure plate 402, a limit screw 404, a serrated column 403 and an adapter 405. The first pressure plate 401, the second pressure plate 402, the serrated column 403 and the adapter 405 are made of aluminum alloy, and the limit screw 404 adopts an M5 stainless steel pan head machine screw.

[0091] Specifically, the first pressing plate 401 and the second pressing plate 402 are arranged in coordination to form a point-type pressing plate structure of two adjacent glass units 200. A first limiting sleeve 4011 is provided at the lower position of the inner side end of the first pressing plate 401, and a first circular sawtooth hole 4012 that is vertically through and open at the side is provided in the first limiting sleeve 4011.

In order to facilitate the compression and fixation of the sub-frame pressing block 302 in the inverted U-shaped notch 101, a U-shaped opening 4061 is pre-opened at the top or bottom of the clamping plate 406.

[0101] The sub-frame pressing block 302 in the inner hidden frame fastener 300 is pressed and fixed to the outer end surfaces of the clamping plate 406 and the first clamping slot 103 on both sides of the notch by the first locking bolt 301 through the U-shaped opening 4061 at the top or bottom of the clamping plate 406.

[0102] See also Figures 1 to 18 As shown in the figure, the installation principle of the adjustable fully hidden point support frame curtain wall system is as follows:

[0103] First, a pair of first fasteners 303 and second fasteners 304 that are interlocked with each other and connected in a concentric circle are designed in the inverted U-shaped notch 101 on the inner side of two adjacent glass units 200. The first fastener 303 and the second fastener 304 can rotate relative to each other within a pair of angles to meet the requirements of different angles of the glass units 200. During installation, the two adjacent glass units 200 are placed at a certain angle to the corresponding position, and then the first locking bolt 301 is slid from the top into the first slot 103, and the sub-frame pressing block 302 is locked to the column 100 through the first locking bolt 301 using a nut.

[0104] Then, in the inverted U-shaped groove 101 at the front end of the column 100, the one-piece aluminum alloy adapter consisting of the sawtooth column 403, the adapter 405, the clamping plate 406 and the second locking bolt 407 is slid into the inverted U-shaped groove 101, and is correspondingly buckled in the first clamping groove 103 and the second clamping groove 104 at the two sides, and the one-piece aluminum alloy adapter is fixed to the column 100 using nuts and second locking bolts 407 respectively; after the two adjacent glass units 200 are installed in place, the first pressure plate 401 and the second pressure plate 402 are pre-placed to the corresponding angles, and the pressure plates on both sides are inserted into the sawtooth column 403 from the top and bottom directions along the direction of the sawtooth for self-locking, and then the limit screws 404 are fixed at the upper and lower ends of the sawtooth column 403 to prevent the first pressure plate 401 and the second pressure plate 402 from falling off.

[0105] In the present system, the inner hidden frame fastener 300 on the inner side of the glass unit 200 is mainly composed of two first fasteners 303 and second fasteners 304 arranged in concentric circles, and the point-type external pressure plate fastener 400 on the outer side of the glass unit 200 is mainly fixed to the column 100 serving as the curtain wall keel through an aluminum alloy adapter composed of a serrated column 403, an adapter 405, a clamping plate 406 and a second locking bolt 407.

[0106] The system adopts the form of mechanical connection as a whole to adjust and fix the connection angle of two adjacent glass units. It is simple to install, easy and quick to operate, and has a stable and reliable structure, which improves the adjustability and safety of the overall curtain wall structure. It overcomes the limitations of the existing semi-hidden frame curtain wall structure, combines the advantages of the point-type curtain wall, and realizes an adjustable full-hidden point support frame curtain wall system that can adapt to various angle changes.
