Description

Technical Field

[0001] This utility model relates to the field of curtain wall window technology, and in particular to a curtain wall window structure that can span multiple floors. Background Technology

[0002] In modern architecture, with the pursuit of maximum spatial scale and indoor-outdoor transparency, the height and size of glass are increasing, making floor-to-ceiling windows and large glass panes a trend. This places immense pressure on the structural strength of traditional window systems, forcing them to passively increase the thickness and size of building materials, which not only significantly increases costs but also fails to completely eliminate structural safety hazards. Against this backdrop, curtain wall windows have emerged. Their structural system and connection construction retain the superior mechanical properties of curtain wall systems while also offering the advantages of factory prefabrication and convenient installation of window systems, and their visual appeal is also more aesthetically pleasing than that of traditional window systems.

[0003] Traditionally, curtain wall windows are typically installed only within the concrete openings on each floor (i.e., the window frame is completely within the concrete opening), with the inter-floor areas finished with paint, stone, or metal panels, making it impossible to install glass panels continuously along the building's height. To prevent waterproofing, each floor's concrete opening is designed as a stepped, single-step structure, with the window frame installed on the stepped surface (i.e., the window frame is completely within the stepped surface). The window frame is first fabricated and assembled in the factory according to the design drawings, and process holes and installation holes are pre-drilled on two parallel surfaces of the top frame, bottom frame, and side frame profiles according to the wall connection design requirements. Once the window frame arrives on site, installation holes for fixing bolts are drilled at corresponding positions in the concrete window openings, based on the locations of the installation holes on the top frame, bottom frame, and side frame. The window frame is then embedded into the concrete opening, and fixing bolts are inserted into the installation holes through the process holes to connect and secure the top frame, bottom frame, and side frame to the concrete structure. Finally, special caps are placed over the process holes to complete the window frame installation.

[0004] However, on the one hand, people hope that curtain wall windows will no longer be limited to installation within the concrete openings on each floor, but can be installed across floors; on the other hand, for super high-rise buildings, the wind load is large, and the existing practice of requiring holes to be drilled in the profiles causes mechanical damage to the profiles, and the potential for water leakage and seepage should also be completely resolved; in addition, the existing installation method of curtain wall windows has poor fault tolerance. Because the position of the installation hole is fixed, when the main concrete structure has steel bars or other reasons that prevent drilling, it is impossible to install the fixing bolts, and the holes must be skipped, resulting in a fixing gap that is detrimental to the stress on the window structure. Utility Model Content

[0005] The purpose of this utility model is to provide a curtain wall window structure that can span multiple floors and is easy to install, in order to address the shortcomings of the above-mentioned background technology.

[0006] To achieve the above objectives, this utility model provides a curtain wall window structure that can span multiple layers, including an upper top frame, a lower bottom frame, a central column, side columns, interlayer glass panels, cross-layer glass panels, a first connecting code, and a second connecting code.

[0007] The top frame, the bottom frame, the middle column, and the side columns constitute a window frame unit;

[0008] The interlayer glass panel is located within the window frame unit, and the cross-layer glass panel is located between two adjacent window frame units. The interlayer glass panel and the cross-layer glass panel are respectively connected to the corresponding central column, side column, top frame, or bottom frame.

[0009] The interlayer glass panel and the cross-layer glass panel are located outside the opening in the main concrete structure. The window frame unit is located outside the opening in the main concrete structure. The front and rear of the top frame and the bottom frame are provided with connection points. The front connection point is connected to the main concrete structure through the first connection code, and the rear connection point is connected to the main concrete structure through the second connection code.

[0010] Furthermore, an interlocking assembly structure is provided between the side columns where two adjacent window frame units meet, and the interlocking assembly structure is used for assembling and splicing two adjacent window frame units.

[0011] Furthermore, the connection point is a connection groove.

[0012] Furthermore, the first connecting code is connected to the upper top frame or the lower bottom frame through the corresponding connecting groove and fastening bolt.

[0013] Furthermore, the second connection code is connected to the top frame or the bottom frame via the corresponding connection slot.

[0014] Furthermore, the first connection code is configured as L-shaped, and both the short and long sides of the first connection code are provided with connection holes.

[0015] Furthermore, adjustment pads are provided at the connection positions of the short and long sides of the first connecting code, and the surfaces of the adjustment pads that contact the first connecting code are all serrated.

[0016] Furthermore, the second connection code is configured as a T-shape, and a connection hole is provided on the long side of the second connection code.

[0017] Furthermore, the opening in the concrete main structure is provided with a primary step and a secondary step, the secondary step corresponding to the second connecting code.

[0018] Furthermore, the secondary step-off platform is configured in an intermittent distribution form.

[0019] The above-mentioned solution of this utility model has the following beneficial effects:

[0020] The cross-layer curtain wall window structure provided by this utility model, through the setting of upper top frame, lower bottom frame, middle column, side column, inter-layer glass panel, cross-layer glass panel, first connecting code and second connecting code, etc., can directly use the window frame unit to realize the cross-layer installation of glass panels, meet the requirements of all-glass public building facades. The structural optimization of the upper top frame and lower bottom frame and the matching of the first connecting code and the second connecting code avoid mechanical damage to the profile by the opening and completely eliminate the hidden danger of water leakage. In addition, the specific structure of the first connecting code and the second connecting code, as well as the matching setting of the first and second setbacks of the concrete main structure, make the installation drilling have a certain adjustment range and eliminate the adverse effects of fixed connection defects.

Detailed Implementation

[0029] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 As shown, an embodiment of this utility model provides a cross-layer curtain wall window structure, including a window frame unit formed by an upper top frame 1, a lower bottom frame 2, a central column 3, and side columns 4, as well as interlayer glass panels 5 located within the window frame unit and cross-layer glass panels 6 located between two adjacent window frame units. For positions within the window frame unit that require opening, a horizontal frame and an operable sash are also provided. For the cross-layer glass panels 6, the installation method eliminates the need for additional keel profiles at the interlayer positions (directly utilizing the profiles of the upper and lower window frame units). The interlayer glass panels 5 and cross-layer glass panels 6 are respectively connected to the corresponding profiles (central column 3, side column 4, upper top frame 1, lower bottom frame 2) through corresponding glass panel connecting brackets 7, connecting screws 8, glass pressure blocks 9, and pressure block covers 10.

[0033] In this embodiment, the window frame unit is connected to the concrete main structure 11 via an upper top frame 1 and a lower bottom frame 2, thereby fixing the window frame unit to the concrete main structure 11. Meanwhile, as Figure 3 , Figure 4 As shown, the side posts 4 are located on the left and right sides of the window frame unit, and the center post 3 is located in the middle of the window frame unit. Both the side posts 4 and the center post 3 are vertically arranged (in terms of their installed position). The top frame 1 and the bottom frame 2 are located on the top and bottom sides of the window frame unit, with their ends connected to the ends of the corresponding side posts 4 and their middle positions connected to the ends of the center post 3. To achieve the connection with the center post 3 and the side posts 4, multiple C-shaped rib grooves are provided in the cavities of the top frame 1 and the bottom frame 2. The top frame 1 and the bottom frame 2 are firmly connected to the corresponding side posts 4 by connecting screws 8 inserted into the C-shaped rib grooves; the center post 3 is fastened to the top frame 1 and the bottom frame 2 by connecting inserts and connecting screws 8 inserted into the C-shaped rib grooves.

[0034] At the same time, such as Figure 2 As shown, for the inter-layer window frame unit, in order to achieve a sealed splicing between the left and right window frame units, an interlocking splicing structure is also provided between the side columns 4 of the two adjacent window frame units, that is, the left column and the right column. The interlocking splicing structure is used to achieve the assembly and splicing between adjacent window frame units, so that the gaps are sealed as much as possible and the overall integrity is improved.

[0035] To achieve continuous arrangement of glass panels along the building's height, this embodiment, compared to traditional methods, moves the glass panels outward from the opening in the concrete main structure 11, allowing them to completely cover the outer surface of the building (consistent with the decorative effect of the glass curtain wall). Correspondingly, to provide installation space for the multi-layered glass panels 6, the window frame units also need to be moved outward from the opening in the concrete main structure 11. Simultaneously, to address the leakage and seepage problems caused by mechanical damage from drilling connection holes in the window frame unit profiles, this embodiment uses a non-drilling connection method with connecting grooves and connecting brackets. Therefore, after the window frame units are moved outward, the front parts of the upper top frame 1 and lower bottom frame 2 need to extend outward from the opening in the concrete main structure 11, becoming a cantilevered load-bearing structure. To maintain the stability of the window frame units, this embodiment employs a two-point support structure, requiring a connection point at the front of the upper top frame 1 and lower bottom frame 2, and another connection point at their rear, thus correspondingly providing a first connecting bracket 12 and a second connecting bracket 13.

[0036] At the same time, such as Figure 5As shown, connecting grooves are provided at the front bottom and rear side of the lower frame 2. The first connecting bracket 12 is L-shaped and is fitted at the right angle formed by the lower frame 2 and the concrete main structure 11. The length of the short side of the first connecting bracket 12, i.e., the length extending out of the concrete main structure 11, is the same as the length of the lower frame 2 protruding from the concrete main structure 11, to maintain alignment. The first connecting bracket 12 is connected to the lower frame 2 by fastening bolts 14. During installation, the fastening bolts 14 can be inserted from the end of the lower frame 2 first, so that the nuts of the fastening bolts 14 are located in the connecting groove at the front bottom of the lower frame 2. The short side of the first connecting bracket 12 has a connecting hole (elongated hole). Therefore, after the fastening bolts 14 pass through the connecting hole on the short side of the first connecting bracket 12, they can be fixed on the other side by a fastening nut, so that the first connecting bracket 12 is firmly connected to the lower frame 2. The long side of the first connecting bracket 12 can be directly connected to the outer wall of the concrete main structure 11 using expansion bolts 15. In this case, the long side of the first connecting bracket 12 also has a connecting hole (elongated hole). As a preferred embodiment, the connection positions of the short and long sides of the first connecting bracket 12 are also provided with adjusting pads 18. The surfaces of the adjusting pads 18 that contact the first connecting bracket 12 are all serrated to facilitate locking after tightening.

[0037] The second connecting bracket 13 is T-shaped. During installation, the short side of the second connecting bracket 13 is first inserted into the connecting groove located on the rear side of the lower bottom frame 2 from the end of the lower bottom frame 2, so that the long side of the second connecting bracket 13 fits against the inner wall of the opening in the concrete main structure 11. The long side of the second connecting bracket 13 also has a connecting hole (round hole), which can be connected to the concrete main structure 11 by expansion bolts 15. Therefore, by connecting the first connecting bracket 12 and the second connecting bracket 13 to the concrete main structure 11 respectively and arranging them in pairs, the window frame unit can be firmly installed on the concrete main structure 11.

[0038] As for the top frame 1, it is also connected to the concrete main structure 11 through the first connecting code 12 and the second connecting code 13, and its installation is mirrored with that of the bottom frame 2. This will not be elaborated further here.

[0039] It should be noted that, for waterproofing purposes, the openings in the concrete main structure 11 are typically designed with a primary stepped-back 16 and filled with sealant. In this embodiment, due to the inclusion of a second connecting bracket 13, if only a primary stepped-back 16 is used, the extended length of the expansion bolts 15 of the second connecting bracket 13 after installation would affect the laying of the interior decorative surface. Therefore, a secondary stepped-back 17 is further installed in the openings of the concrete main structure 11. Considering the convenience of later interior finishing with mortar, the secondary stepped-back 17 is optimized from a continuous form to an intermittent arrangement. Each secondary stepped-back 17 has a certain width, meaning its width is greater than the long side width of the second connecting bracket 13. When encountering reinforcing bars or expansion bolts 15 at a certain location where installation is impossible, the second connecting bracket 13 can slide along the corresponding connecting groove, adjusting its installation position within the allowable width range of the secondary stepped-back 17. Typically, the width of the secondary stepped-back 17 should allow for an adjustment range of 3cm to 5cm for the expansion bolts 15. The secondary stepped-back 17 needs to be formed according to the curtain wall window installation design requirements during pouring.

[0040] Using the cross-floor curtain wall window structure provided in this embodiment, the window frame units can be prefabricated in the factory. At this time, the upper top frame 1 and lower bottom frame 2 of the window frame unit are clamped by the paired side columns 4. Therefore, the ends of the upper top frame 1 and lower bottom frame 2 will be closed and blocked by the side columns 4. After the window frame unit is assembled, it will be impossible to fill the corresponding connection slots of the upper top frame 1 and lower bottom frame 2 with the second connecting bracket 13 and fastening bolt 14. Therefore, before assembling the window frame unit, a sufficient number of second connecting brackets 13 and fastening bolts 14 should be filled into the corresponding connection slots of the upper top frame 1 and lower bottom frame 2 according to the connection design scheme. Then, the assembled window frame unit is transported to the installation site. The first connecting bracket 12 is pre-installed on site. One first connecting bracket 12 is pre-installed for every two fastening bolts 14 (the fastening nuts are not tightened at first). At the same time, bolt holes are opened at the corresponding positions of the concrete main structure 11 (positions where drilling is not possible can be changed and adjusted). Based on the specific position of the secondary setback 17, first roughly adjust the positions of the first connecting bracket 12 and the second connecting bracket 13 (to ensure that the window frame unit can smoothly enter the opening). After adjustment, push the entire window frame unit parallel to the opening along the direction from the outside to the inside. Whether it is in place is determined by aligning the connecting hole on the second connecting bracket 13 with the bolt hole on the secondary setback 17. Adjust the front and rear positions of the first connecting bracket 12 to ensure that its long side is in contact with the outer wall sidewall of the concrete main structure 11. Then, finely adjust the left and right positions of the first connecting bracket 12 according to the bolt hole position. After it is in place, first tighten the nuts of the fastening bolts 14 to lock the first connecting bracket 12 and the upper top frame 1 or the lower bottom frame 2 into the relative position. Then, install the expansion bolts 15 and tighten them. Finely adjust the position of the second connecting bracket 13 according to the bolt hole position. After it is in place, install the expansion bolts 15 and tighten them. Install the interlayer glass panel 5 in the window frame unit, and finally install the cross-layer glass panel 6.

[0041] If long-distance transportation is required or if it is necessary to maximize the use of space in the carriage, container, etc. during transportation, it is best not to pre-install the second connecting code 13 and fastening bolt 14 at the factory, which can also avoid damage during transportation. At this point, it is necessary to adjust the structural form and assembly scheme of the window frame unit. The side columns 4, which are paired and arranged at both ends of the upper top frame 1 and lower bottom frame 2, are now clamped at both ends of the side columns 4. That is, all vertical components such as the side columns 4 and the middle column 3 need to be scaled down before being spliced ​​with the upper top frame 1 and lower bottom frame 2. The exposed ends of the upper top frame 1 and lower bottom frame 2 need to be sealed with special plugs. The window frame unit is manufactured in the factory and transported to the installation site. According to the actual situation of the secondary setback 17 of the opening, the fastening bolts 14 and the second connecting codes 13 of the corresponding number of first connecting codes 12 are respectively poured into the corresponding connecting grooves from one end of the upper top frame 1 and the lower bottom frame 2. Then, a first connecting code 12 is pre-installed at every two fastening bolts 14 (without tightening the fastening nuts first). At the same time, bolt holes are opened on the concrete main structure 11 (the positions where drilling is not possible can be changed and adjusted). Based on the specific position of the secondary setback 17, first roughly adjust the positions of the first connecting bracket 12 and the second connecting bracket 13 (to ensure that the window frame unit can smoothly enter the opening). After adjustment, push the entire window frame unit parallel to the opening along the direction from the outside to the inside. Whether it is in place is determined by aligning the connecting hole on the second connecting bracket 13 with the bolt hole on the secondary setback 17. Adjust the front and rear positions of the first connecting bracket 12 to ensure that its long side is in contact with the outer wall sidewall of the concrete main structure 11. Then, finely adjust the left and right positions of the first connecting bracket 12 according to the bolt hole positions. After it is in place, first tighten the nuts of the fastening bolts 14 to lock the first connecting bracket 12 and the upper top frame 1 or the lower bottom frame 2 into the corresponding position. Then, install the expansion bolts 15 and tighten them. Finely adjust the position of the second connecting bracket 13 according to the bolt hole positions. After it is in place, install the expansion bolts 15 and tighten them. Install the interlayer glass panel 5 in the window frame unit, and finally install the cross-layer glass panel 6.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
