Description

Technical Field

[0001] This utility model relates to the field of curtain wall installation technology, specifically a top-and-bottom grooved all-glass window-style curtain wall installation system. Background Technology

[0002] There are generally three types of all-glass curtain walls: window-style curtain walls, suspended curtain walls, and ribbed curtain walls. Window-style curtain walls are fixed at the top and bottom using U-slots, with the glass panels and ribs directly touching the ground, transferring weight to the floor. Suspended curtain walls have upper hanging clamps supporting the weight of the glass panels and ribs. The difference in their applicability lies in the fact that suspended curtain walls must be used when a single panel height exceeds a certain value, while window-style curtain walls can be used within a certain range. According to regulations, taking 19mm thick glass as an example, if the height exceeds 6m, the all-glass curtain wall should be suspended from the main structure. Window-style and suspended curtain walls typically consist of a single piece of glass from top to bottom. Ribbed curtain walls, on the other hand, vertically divide the glass into several sections. In ribbed curtain walls, except for the bottom panel which can touch the ground, the weight of the remaining panels is transferred to the ribs via ribs, and then upwards through the ribs. The ribs bear almost the entire weight of the panel, making them more prone to instability. Therefore, the design typically uses 80% of the height limit.

[0003] A steel structure staircase is to be installed on the exterior of a complex building in a certain project. The staircase is five stories high, with each floor height of 3.8 meters. The main beams of the staircase are made of H-beams, with ear plates welded to the upper and lower flanges on the outside of the H-beams. Six double-eared, high-strength steel tie rods, each 45mm in diameter, are installed from top to bottom through the ear plates. After the main steel structure is installed, but before the stair slabs are constructed, the railings are tensioned, with the tension controlled at 60KN. The glass panels are 10+152PVB+10LOW-E+12A+10 ultra-clear tempered laminated insulated glass, divided into sections with both curved and straight sections. The client requires a full glass curtain wall to be installed on the exterior of the steel structure staircase, which has been submitted to and approved by the planning bureau. Based on three types of all-glass curtain walls, the following approaches can be considered: First, a window-style curtain wall, typically directly supported by beams. Since this type of curtain wall uses an external mounting method, direct support is not feasible. The solution is to add steel beams between rest platforms (between floor heights). Second, a suspended curtain wall can be considered. First, the hanging points need to be considered. Similar to the window-style curtain wall, the hanging points are solved by adding steel beams. The vertical division can be set at 3.8m. Then, each unit (2 panels) is fixed with 4 hanging clamps, and each panel is fixed with 2 hanging clamps. If necessary, glass ribs are added between the two panels, and the glass ribs are fixed with hanging clamps above them. Third, a rib-jointed curtain wall can be considered. First, the number of steel beams to be added is determined through stress calculations. There are two installation methods for the curtain wall. The first installation method uses an upper lifting clamp and a lower support. In each vertical unit, except for the bottom glass panel which rests on the ground, the weight of the remaining panels is transferred to the glass ribs via connecting claws and borne by the upper lifting clamp. The selection of the lifting clamp needs to consider the weight of the glass ribs themselves and the weight of the panels in each unit, and comprehensively determine the total number of steel beams to be installed vertically. The second installation method uses welded ear plates on the outside of the steel beams and also welded ear plates on the outside of the glass rib connectors. The two are connected by high-strength bolts. Therefore, the force transmission path is from the panel to the glass ribs, and then from the glass ribs to the steel beams. Compared with the first installation method, each unit bears a greater weight.

[0004] Based on the above three installation methods for all-glass curtain walls, and considering the characteristics of this project, we will select an installation method that is fast, has clear stress distribution, is safe and reliable, and is cost-effective. We can utilize the installation principle of the first type of window-style curtain wall, modify and refine the corresponding nodes, and then invent a method for installing all-glass curtain walls using H-beams inserted into grooves at the top and bottom. Summary of the Invention

[0005] In view of the above-mentioned prior art, this utility model proposes a top-and-bottom grooved all-glass window-style curtain wall installation system.

[0006] This utility model provides a top-and-bottom grooved all-glass window curtain wall installation system, in which a ring beam is set along the steel tie rod between the platform beams. The ring beam adopts a steel slot, which is connected to the platform beam in sequence through T-shaped connectors and C-shaped connectors. The steel slot is connected to the steel tie rod in sequence through T-shaped connectors and clamps. The upper and lower sides of the glass panel are respectively inserted into the corresponding steel slots.

[0007] Preferably, both ends of the steel tie rod are connected to a single ear plate on the platform beam via double ear plates.

[0008] Preferably, the steel slot includes a central web and two side flanges. The web has a thickness of 15mm, the flanges have a height of 150mm, and the width of the steel slot is greater than the thickness of the glass panel, by 10mm on each side.

[0009] Preferably, the clamp includes two clamping plates, which are made of 20mm thick steel plates. The clamping plates are provided with four bolt holes arranged in a square. The two clamping plates are fixed together by M12 high-strength bolts. A hard rubber pad is provided on the inner side of the clamping plates.

[0010] Preferably, the T-shaped connector, C-shaped connector, and fixture are connected by full penetration bevel welding.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Excellent transparency: The glass panel is supported only by the H-shaped steel slots of each layer, with almost no obstruction, achieving the best view through the glass and providing a wide field of vision, maximizing the transparency of the glass.

[0013] Visual effects: Due to its ultra-wide and ultra-high visual effect, the window-style glass curtain wall can provide a wider field of vision and a better display effect, making it suitable for occasions that require display space.

[0014] Decorative: Due to its transparency, the window-style glass curtain wall can serve as a decorative structure for a building, enhancing its modernity and aesthetics.

[0015] Applications: In addition to traditional indoor exhibition halls, window-style glass curtain walls can also be used for the exterior decoration of buildings, enhancing their visual appeal and commercial value.

[0016] Structural features: This window-style glass curtain wall can be installed quickly, has clear stress distribution, is safe and reliable, and is cost-effective. If this window-style curtain wall is used in scenarios with tall glass, it can also be combined with suspension, rib connection and other methods. It adopts a hanging system to suspend it on the main structure, with the glass panels embedded in the steel channels at the top and bottom, and a single rib support at the rear. The four sides are fixed and sealed with structural adhesive to meet different needs in actual projects. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example: Figure 1 , 2 The above-display grooved all-glass window curtain wall installation system includes a ring beam installed along the steel tie rod 2 between the platform beam 1 and the platform beam 1. The ring beam uses a steel slot 5, and both ends of the steel tie rod 2 are connected to the single ear plate on the platform beam 1 through double ear plates.

[0022] Furthermore, the platform beam 1 is connected to the open end of the C-shaped connector 3, the closed end of the C-shaped connector 3 is connected to the narrow end of the T-shaped connector 4, and the wide end of the T-shaped connector 4 is connected to the outer end of the steel slot 5. The steel tie rod 2 is connected to the clamp 6, the clamp 6 is connected to the narrow end of the T-shaped connector 4, and the wide end of the T-shaped connector 4 is connected to the outer end of the steel slot 5. The upper and lower sides of the glass panel 7 are respectively inserted into the corresponding steel slots 5.

[0023] The steel slot 5 includes a central web and two side flanges. The web is 15mm thick and the flanges are 150mm high. The width of the steel slot 5 is greater than the thickness of the glass panel 7 by 10mm on each side.

[0024] The clamp 6 includes two clamping plates made of 20mm thick steel plates. Each clamping plate has four square bolt holes. The two clamping plates are fixed together by M12 high-strength bolts 8. A hard rubber gasket is placed on the inner side of each clamping plate. The T-shaped connector 4, C-shaped connector 3, and clamp 6 are connected by full-penetration bevel welding.

[0025] In this embodiment, the T-shaped connector 4, installed between the steel slot 5 and the clamp 6 and C-shaped connector 3, serves to connect, convert, and eliminate deviations between the internal and external components. If the external steel slot 5 is directly welded to the internal clamp 6 and C-shaped connector 3, deviations in the verticality of the main steel structure will be found during actual construction measurements. Deviations will also exist in the installation of the internal clamp 6 and the welding of the C-shaped connector 3. If no measures are taken and the internal and external components are rigidly welded directly, the deviations cannot be eliminated, the installation verticality of the steel slot 5 cannot be guaranteed, and the installation verticality and flatness of the glass panel 7 cannot be guaranteed either. The advantage of using the T-shaped connector 4 is that first-hand construction deviation data can be obtained through construction measurements. When feeding back to the back-end processing, only the web width of the T-shaped connector 4 needs to be adjusted and cut, which can achieve uniform spacing between the internal and external components, thereby ensuring the installation quality of the steel slot 5 and providing good conditions for the subsequent installation of the glass panel 7. If the steel slot 5 is connected to the clamp 6 and C-type connector 3 by bolts, it can eliminate internal and external deviations and adjust the verticality. However, it requires extremely high precision in the opening of the bolt holes on each component. Each fixing point has 4 bolt holes arranged in a square. If there is a slight machining deviation, the bolts cannot pass through. The on-site installation process is more complicated. The bolt tightening degree of each point needs to be adjusted in real time according to the installation precision requirements. The installation workload is also large. If there are omissions during the construction process, the panel installation in the later stage will need to be re-measured, checked and adjusted.

[0026] In addition, by setting symmetrical clamps on the steel tie rod 2, the steel tie rod 2 is clamped by the clamps, thereby providing a fixing point for the steel slot 5, and the connection between the internal and external components is realized by using the T-shaped connector 4.

[0027] This embodiment adopts a window-style curtain wall installation method, which enables rapid installation, clear stress distribution, safety, reliability, and cost-effectiveness. First, a ring beam is installed at the elevation of the rest platform level, fixed to platform beam 1. The intermediate positions between platform levels are secured by clamps 6 on steel tie rods 2. The spacing of the ring beams is half the floor height, reducing the cost per glass panel by decreasing the vertical panel height. During the glass panel 7 installation stage, a special glass installation suction cup is used to hoist the glass panel 7 into the steel slot 5. A special hard rubber pad is pre-installed in the lower slot opening, and the glass panel 7 rests on the rubber pad. The upper end of the glass panel 7 is embedded in the upper slot opening. Finally, a hard rubber pad is used to line the space between the steel slot 5 and the glass panel 7. Adjacent glass panels 7 at the same level are sealed with PE foam rods and sealant. The steel slot 5 is painted for protection according to the exterior facade decoration style.

[0028] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent solutions made using the contents of this utility model specification, whether directly or indirectly applied to other related technical fields, are also within the patent protection scope of this utility model.
