Description

Technical Field

[0001] This application belongs to the technical field of building structure connection devices, specifically relating to an installation structure for prefabricated frame curtain walls. Background Technology

[0002] As a building envelope system, framed curtain walls consist of a load-bearing frame made of columns and beams constructed on the outside of the main building structure, to which panels are fixed. With its advantages of flexible design and strong adaptability, it is widely used in the facade engineering of modern high-rise and super high-rise buildings. However, the construction of traditional framed curtain walls is highly dependent on on-site operations. The installation, connection, and sealing of its components are mostly done manually, and the construction accuracy is easily affected by factors such as the worker's skill level, on-site temperature and humidity, and cross-operation environments. This often leads to quality problems such as loose connections between columns and beams, uneven sealant joints, and seal failure, which not only affect the overall appearance and durability of the building but may also cause safety hazards such as leakage, structural loosening, and even panel detachment. As the construction industry's requirements for construction efficiency and project quality increase, the traditional on-site wet-work construction mode can no longer meet the needs of industrialization and standardization. Curtain wall construction urgently needs to transform towards a higher level of integration and prefabrication.

[0003] Prefabricated frame curtain walls, as an upgrade from traditional curtain wall construction methods, are gradually becoming the mainstream trend in the development of modern building envelope systems. This technology involves standardized design, precision machining, and overall pre-assembly of columns and other components in a factory, forming integrated curtain wall unit modules with functions such as structural integrity, thermal performance, and airtightness. These modules are then transported to the construction site and rapidly hoisted and precisely positioned using a dedicated connection system. This integrated design-manufacturing-assembly construction model represents a shift from on-site construction to industrial manufacturing, significantly reducing on-site wet work, welding, and manual assembly, effectively mitigating the impact of factors such as climate and fluctuations in the skill level of construction workers on project quality. Simultaneously, factory production ensures high consistency in component dimensions and precise matching of connection interfaces, significantly improving the installation efficiency, structural reliability, and aesthetic quality of the curtain wall system, meeting the comprehensive requirements of modern architecture for high quality, short construction periods, and green construction. However, semi-prefabricated frame curtain walls remain more common at present.

[0004] For example, patent number 202222623204.3 discloses a semi-prefabricated frame curtain wall. Through the coordinated design of grooved embedded parts, T-shaped adapters, waist hole adjustment, and sawtooth anti-slip structure, it achieves three-dimensional adjustability and high-precision fixing of the column installation, effectively reducing on-site welding and improving connection reliability. However, in the connection between the beams and columns within or between curtain wall units, on-site welding or semi-prefabricated connection methods are still relied upon. This type of process not only damages the anti-corrosion coating on the surface of aluminum alloy or steel components, reducing durability, but also makes it difficult to control the thermal deformation generated during welding, easily leading to problems such as beam positioning misalignment and interface misalignment. Such dimensional deviations directly affect the flatness and sealing performance of the subsequent panel installation, causing hidden dangers such as inconsistent glue joint width, incomplete closure, and even uneven structural stress. Utility Model Content

[0005] The purpose of this application is to provide a frame curtain wall installation structure that allows for the prefabricated installation of beams and columns, specifically achieved through the following technical solution:

[0006] A prefabricated frame curtain wall installation structure includes columns, brackets embedded in the main structure of the building, and brackets for connecting the columns and the brackets; a horizontal beam is provided between two adjacent columns; a horizontal beam insert is fixedly fixed on the opposite side wall of the adjacent columns, and the inserted horizontal beam is sleeved on the outside of the horizontal beam insert and fixedly connected to it; a set of horizontal beam grooves are provided on the side of the inserted horizontal beam away from the main structure of the building for installing the horizontal beam.

[0007] Preferably, the plug-in crossbeam includes a main body for housing the crossbeam insert and a plug-in sub-frame for slidingly connecting with the main body to adjust the distance between a set of crossbeam grooves.

[0008] Preferably, the main body is provided with an installation part for forming the crossbeam groove on the side away from the main structure of the building, and a groove extending from bottom to top is formed at the connection position between the installation part and the main body; the plug-in sub-frame includes a fitting part adapted to the groove, and the fitting part is provided with an elastic snap-fit ​​member for engaging with the inner wall of the groove.

[0009] Preferably, the crossbeam groove is provided on the side of the plug-in sub-frame away from the main structure of the building; the plug-in crossbeam also includes a sub-frame connector for fixing the plug-in sub-frame to the column.

[0010] Preferably, the sub-frame connector includes a base connecting part for detachably and fixedly connecting with the column, and a fastening part formed by the base connecting part extending along a direction perpendicular to the opposite side surface of the column; the inner wall of the plug-in sub-frame is provided with a fastening cavity adapted to the structure of the fastening part, and the upper wall of the fastening cavity abuts against the upper surface of the fastening part.

[0011] Preferably, the mounting bracket includes a column locking plate fixedly connected to the column, and the column locking plate is fixedly connected to the column by a connector; the column locking plate also extends to the side near the main structure of the building and is provided with a mounting bracket docking part for detachable and fixed connection with the mounting bracket.

[0012] Preferably, the mounting bracket docking part includes a lifting groove extending upward in a vertical direction; the mounting bracket includes a set of ear plates distributed on opposite sides of the main body of the mounting bracket, and a connector for passing through the lifting groove and being fixed at both ends to the set of ear plates.

[0013] Preferably, the prefabricated frame curtain wall installation structure also includes a distal column that is fixedly connected to the column via a rigid frame structure; the surface of the rigid frame structure is fitted with a panel.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] This application constructs a fully prefabricated connection structure between the beams and columns by fixing corresponding horizontal beam inserts to the opposite sidewalls of adjacent columns, and then fitting the insert beams onto the outside of these inserts for secure connection. Simultaneously, corresponding horizontal beam grooves are provided on the side of the insert beam furthest from the main building structure for beam installation, creating a fully prefabricated connection between the beams and columns. This design completely eliminates the on-site welding process relied upon in traditional semi-prefabricated curtain walls, effectively preventing damage to the anti-corrosion coating of components during welding, significantly improving the durability of the curtain wall system, and extending its service life. It also eliminates beam positioning misalignment and interface misalignment caused by welding thermal deformation, ensuring component dimensional accuracy and connection stability, thereby ensuring the flatness of subsequent panel installation and the uniform sealing of the sealant joints, preventing safety hazards such as leakage and uneven structural stress. Furthermore, the prefabricated structure of this application allows for factory pre-processing of beams and columns and rapid on-site assembly, significantly reducing on-site wet work, improving construction efficiency, and aligning with the development needs of industrialization, standardization, and green construction in the building industry.

[0016] This application designs the interlocking crossbeam as a structure comprising a main body for housing the crossbeam insert and an interlocking sub-frame that slides vertically and vertically connected to the main body. By utilizing the sliding fit between the main body and the interlocking sub-frame, the distance between a set of crossbeam grooves can be flexibly adjusted. This breaks the limitations of traditional fixed-size interlocking structures and allows for dynamic adjustment of the crossbeam groove spacing based on differences in crossbeam specifications, panel installation requirements, or changes in building facade design during actual construction. This significantly improves the adaptability of the installation structure to different curtain wall design scenarios and reduces the cost of rework or replacement of components due to size mismatch.

[0017] This application establishes an installation section forming a horizontal beam groove on the side of the main body away from the building's main structure. An upward-extending groove is created at the connection point between the installation section and the main body. The plug-in sub-frame is designed to include a fitting part that mates with the groove, and an elastic locking component that engages with the inner wall of the groove is provided on the fitting part. This mating structure between the groove and the fitting part provides precise guidance for the vertical sliding of the main body and the plug-in sub-frame, preventing offset and jamming during adjustment and ensuring the stability and accuracy of the horizontal beam groove spacing adjustment. Furthermore, the structural design allows for the installation and adjustment of the plug-in sub-frame without complex tools, effectively reducing on-site construction difficulty and further shortening installation time. The elastic locking component also provides a certain degree of buffer tolerance, adapting to slight temperature deformation or structural settlement, thus improving the overall deformation resistance of the curtain wall system.

[0018] This application incorporates a crossbeam groove on the side of the plug-in sub-frame away from the main building structure. The sub-frame connector is designed to include a base connection portion detachably fixed to the column and a fastening portion extending from the base connection portion along a direction perpendicular to the column's surface. A fastening cavity is provided on the inner wall of the plug-in sub-frame, fitting the fastening portion and abutting its upper surface. The crossbeam groove on the plug-in sub-frame corresponds vertically to the crossbeam groove formed by the main body's mounting portion. With the precise fit between the fastening cavity and the fastening portion, the distance between the two sets of crossbeam grooves can be stably adjusted by adjusting the position of the plug-in sub-frame within the groove of the main body. Furthermore, the detachable connection design between the base connection portion and the column facilitates adjustment of the sub-frame connector's fixed position during installation according to actual size requirements and allows for quick disassembly and replacement of the plug-in sub-frame during later maintenance, reducing maintenance costs and operational complexity.

[0019] This application designs the mounting bracket as a column locking plate that is fixedly connected to the column via connectors. A mounting base with a vertically extending hoisting groove extends from the side of the column locking plate closest to the main building structure. The mounting base is designed to include a set of ear plates distributed on opposite sides of the mounting bracket body, and connectors that pass through the hoisting groove and are fixed at both ends to the ear plates. The method of fixing the column locking plate to the column connectors ensures the robustness of the connection between the mounting bracket and the column, preventing loosening due to load during long-term use and providing a fundamental guarantee for the overall structural safety of the curtain wall. The design of the vertical hoisting groove of the mounting base connector, along with the ear plates and connectors, allows the mounting bracket to be flexibly adjusted vertically when connected to the mounting base. This facilitates on-site calibration of the column's installation height, effectively avoiding installation difficulties caused by deviations in the position of embedded parts or errors in the main structure construction, and significantly improving the column positioning accuracy. The mounting brackets and supports are detachably and fixedly connected through the hoisting slots, ear plates and connectors, which simplifies the on-site hoisting and assembly process, eliminates the need for complicated welding or drilling operations, reduces construction difficulty and labor costs, and provides convenience for later curtain wall maintenance, repair or partial replacement of columns, avoiding damage to the main structure or surrounding curtain wall components, further meeting the development needs of building industrialization and green operation and maintenance.

[0020] This application adds a remote column to the prefabricated frame curtain wall installation structure, which is fixedly connected to the columns through a rigid frame structure, and installs a panel on the surface of the rigid frame structure. By using the rigid frame structure to form a stable load-bearing whole with the columns and the remote column, the structural bearing capacity of the curtain wall system, such as wind load and earthquake resistance, is greatly improved. It avoids the risk of deformation and collapse caused by large curtain wall spans or external impacts, and is especially suitable for building curtain wall design scenarios with large spans and irregular facades.

Detailed Implementation

[0029] The present application will now be further described by way of specific embodiments. Those skilled in the art will be able to implement the present application based on these descriptions. Furthermore, the embodiments of the present application described below are generally only a part of the embodiments of the present application, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort should fall within the scope of protection of the present application.

[0030] Example 1

[0031] An assembly frame curtain wall installation structure includes columns 100, brackets 300 embedded in the main structure 200 of the building, and brackets 400 for connecting the columns 100 and the brackets 300; a crossbeam 500 is provided between two adjacent columns 100.

[0032] To achieve the prefabricated installation of the crossbeam 500, crossbeam inserts 600 are fixedly fixed on the opposite side walls of adjacent columns 100, and a connecting crossbeam 700 is sleeved on the outside of the crossbeam insert 600 and fixedly connected to it. The connecting crossbeam 700 includes a main body 710 for housing the crossbeam insert 600 and an installation part 730 away from the main structure 200 of the building. A groove 712 extending from bottom to top is formed at the connection position between the installation part 730 and the main body 710, and a crossbeam sliding groove 711 is provided on the side of the installation part 730 away from the main structure 200 of the building.

[0033] The plug-in crossbeam 700 further includes a plug-in sub-frame 720, which includes a fitting portion 721 adapted to the groove 712. The fitting portion 721 is provided with an elastic snap-fit ​​member for engaging with the inner wall of the groove 712. The plug-in sub-frame 720 is provided with a crossbeam slide groove 711 on the side away from the main building structure 200; two crossbeam slide grooves 711 are arranged vertically to install the crossbeam 500.

[0034] Furthermore, the plug-in crossbeam 700 also includes a sub-frame connector 740 for fixing the plug-in sub-frame 720 to the column 100. Specifically, the sub-frame connector 740 includes a base connecting portion 741 for detachably and fixedly connected to the column 100, and a fastening portion 742 formed by the base connecting portion 741 extending along a direction perpendicular to the opposite surfaces of the column 100; the inner wall of the plug-in sub-frame 720 is provided with a fastening cavity 722 adapted to the structure of the fastening portion 742, and the upper wall of the fastening cavity 722 abuts against the upper surface of the fastening portion 742.

[0035] During installation, first, according to the preset spacing of the uprights 100 and the assembly requirements of the crossbeams 500, the crossbeam inserts 600 are precisely fixed to the opposite side walls of the uprights 100 on both sides with bolts to ensure that the axes of the crossbeam inserts 600 on both sides are collinear; then, the main body 710 of the insert crossbeam 700 is sleeved on the outside of the crossbeam insert 600, and the two are initially fixed by the positioning pins or fastening bolts that pass through the main body 710 and the crossbeam insert 600 to prevent the insert crossbeam 700 from shifting during the assembly process. Next, the fitting part 721 of the sub-frame 720 is slid up and down along the groove 712 of the main body 710. At the same time, the distance between the upper and lower sets of crossbeam slide grooves 711 (located on the main body mounting part and the sub-frame 720 respectively) is calibrated with the help of a tape measure or laser rangefinder until the distance is completely matched with the height of the upper and lower sliders of the crossbeam 500. At this time, the elastic snap-fit ​​on the fitting part 721 automatically snaps into the inner wall of the groove 712 to achieve temporary positioning of the sub-frame 720.

[0036] Next, the base connection part 741 of the sub-frame connector 740 is detachably fixed to the column 100 with bolts, ensuring that the fastening part 742 extends horizontally in a direction perpendicular to the surface of the column 100; then push the insertion sub-frame 720 so that the fastening part 742 is precisely inserted into the fastening cavity 722 on its inner wall until the upper wall of the fastening cavity 722 and the upper surface of the fastening part 742 are tightly abutted, forming a vertical load-bearing structure; then further tighten the bolts of the base connection part 741 to complete the final fixing of the insertion sub-frame 720. Subsequently, align the slider of the crossbeam 500 with the opening of the crossbeam groove 711 on one side column 100 where the crossbeam 700 is inserted, and smoothly slide it in horizontally until the slider is completely inserted into the corresponding crossbeam groove 711 on the adjacent column 100, thus achieving the initial assembly of the crossbeam 500. To improve the reliability of the connection, additional self-tapping screws or positioning bolts can be added to fix the crossbeam 500 to the side wall of the groove of the crossbeam 700, preventing the crossbeam 500 from sliding due to vibration or external force during use, and finally completing the complete installation of the crossbeam 500.

[0037] Example 2

[0038] The only difference between this embodiment of the prefabricated frame curtain wall installation structure and Embodiment 1 is that:

[0039] In this embodiment, the mounting bracket 400 includes a column locking plate 410 fixedly connected to the column 100, and the column locking plate 410 and the column 100 are fixedly connected by a connector; the column locking plate 410 also extends to the side near the main structure 200 of the building and is provided with a mounting bracket docking part 420 for detachably and fixedly connected to the mounting bracket 300. The mounting bracket docking part 420 includes a lifting groove 421 extending upward in the vertical direction; the mounting bracket 300 includes a set of ear plates 310 distributed on opposite sides of the main body of the mounting bracket 400, and a connector for passing through the lifting groove 421 and being fixed at both ends to the set of ear plates 310. In this embodiment, the prefabricated frame curtain wall installation structure also includes a distal column 900 fixedly connected to the column 100 through a rigid frame structure 800; a panel 810 is installed on the surface of the rigid frame structure 800.

[0040] During installation, the pre-embedded position of the bracket 300 must first be confirmed according to the construction drawings of the main structure 200 of the building and the positioning benchmark of the curtain wall. Then, the column locking plate 410 of the bracket 400 is attached to the side wall of the column 100. High-strength bolts and other connecting parts are used to pass through the pre-set installation holes of the column locking plate 410 and the column 100. The bolts are tightened to achieve a firm fixation between the two. During the fixing process, the verticality of the column locking plate 410 needs to be calibrated with a level to avoid the bracket docking part 420 from shifting. Next, lift the bracket 400 that is fixed to the column 100, align the lifting groove 421 of the bracket docking part 420 with the space between a set of ear plates 310 of the bracket 300, and slowly lower the bracket 400 until the mounting holes of the ear plates 310 are aligned with the holes of the lifting groove 421. At this time, pass the connector (such as a pin or bolt) through the mounting groove 421 and the mounting holes of the two sets of ear plates 310, add washers and nuts at both ends of the connector and tighten them to fix it, thus completing the connection between the bracket 400 and the bracket 300. If it is necessary to fine-tune the vertical height of the column 100, the connector nut can be loosened, and the bracket 400 can be moved up and down along the vertical direction of the lifting groove 421. After the height is calibrated, the nut can be tightened again to ensure that the installation position of the column 100 is accurate. In addition, after fixing the column 100 and the bracket 300, the installation of the far-end column 900 can begin: First, according to the span and stress requirements of the curtain wall facade design, a rigid frame structure 800 is prefabricated in the factory, ensuring that its two ends match the connection interfaces of the column 100 and the far-end column 900 respectively; on site, one end of the rigid frame structure 800 is inserted and fixed to the preset connection node of the column 100, and the other end is connected to the corresponding node of the far-end column 900. The levelness and straightness of the rigid frame structure 800 are calibrated with a laser rangefinder. After confirming that there are no errors, the connecting bolts are tightened to form a stable load-bearing frame for the column 100 and the far-end column 900; finally, the panel 810 is installed on the surface of the rigid frame structure 800 by means of clips, bolts, etc. During the installation process, it is necessary to ensure that the splicing gaps between the panels 810 are uniform and that they fit tightly with the rigid frame structure 800 to avoid affecting the sealing performance and appearance integrity of the curtain wall due to frame deformation or panel misalignment.
