Description

Technical Field

[0001] This utility model belongs to the field of building door and window structure technology, specifically relating to a large-span beam connection structure. Background Technology

[0002] Building doors and windows serve multiple functions, including ventilation, lighting, and air exchange, as well as exterior facade decoration. Office buildings and residential buildings have high requirements for the regularity of openings; commercial and villa doors and windows often have various shapes, and large-span or duplex windows are common in villa areas. For cases of excessive height or where whole windows cannot be transported, the common practice is to vertically assemble them into two or three windows on-site, dividing a single opening vertically and then assembling them. However, existing technology has the following problems: 1. If the width is large during vertical assembly, the horizontal frame is prone to "waist collapse" deformation, affecting the lifespan and performance of the doors and windows.

[0003] 2. Although welding a whole steel beam directly between the two windows can bear the weight, the steel beam throughout the entire structure damages the window's thermal insulation performance, affecting its appearance and thermal performance.

[0004] 3. On-site assembly quality is difficult to guarantee, and it is also difficult to balance load-bearing capacity with heat insulation, sealing, and waterproofing performance.

[0005] To solve the above problems, a beam connection solution is needed that can provide sufficient load-bearing strength, while maintaining thermal insulation, waterproof sealing, dual-color appearance (inner and outer), and ease of on-site installation. Utility Model Content

[0006] This utility model addresses the aforementioned problems by providing a large-span beam connection structure for bearing vertical and horizontal loads in large-span openings, while maintaining the heat insulation, sealing, and aesthetic appearance of doors and windows.

[0007] This utility model adopts the following technical solution: the utility model includes a crossbeam profile, characterized in that: a core is provided inside the crossbeam profile, a connector is provided on the interior side of the crossbeam profile, a pressure plate is provided on the connector by mounting nails, and a heat-insulating plastic material is provided between the pressure plate and the connector; upper and lower heat-insulating plastic materials are provided on the upper and lower shoulders of the pressure plate and the upper and lower shoulders of the connector of the crossbeam profile; window frame profiles are provided on both the upper and lower sides of the crossbeam profile, and the window frame profiles are fixed together with the crossbeam profile and the core inside the crossbeam profile by screws.

[0008] As a preferred embodiment of this utility model, a waterproof gasket is provided between the pressure plate and the middle heat-insulating plastic material and the upper and lower heat-insulating plastic materials.

[0009] As another preferred embodiment of this utility model, the upper and lower sides of the pressure plate are provided with sealing grooves opposite to the upper and lower heat insulation plastic materials, and sealing strips that contact the upper and lower heat insulation plastic materials are provided in the sealing grooves.

[0010] As a third preferred embodiment of this utility model, a frame adjustment component is also provided between the window frame profile and the beam profile.

[0011] As a fourth preferred embodiment of this utility model, the corner of the insert cross section is provided with nail holes, and the insert is connected to the steel plates at both ends of the crossbeam profile by connecting nails.

[0012] Furthermore, the steel plate is connected to the building structure using expansion bolts.

[0013] As a fifth preferred embodiment of this utility model, a snap-on cover is provided on the inner surface of the pressure plate.

[0014] The beneficial effects of this utility model are: 1. High structural strength and excellent load-bearing performance.

[0015] This utility model, by setting a core structure inside the beam profile, with both ends of the core connected to steel plates, and the steel plates fixed to the building body by expansion bolts, forms a stable force transmission path, which significantly improves the overall load-bearing capacity of the beam and can effectively prevent lateral collapse deformation of large-span windows, thereby improving the safety and durability of the overall structure.

[0016] 2. Form a complete thermal break insulation system.

[0017] This utility model features a connector on the interior side of the beam profile. The connector is secured to a pressure plate by mounting nails. A thermal insulation material is placed between the pressure plate and the connector, and additional thermal insulation materials are added on the upper and lower sides of the pressure plate and the shoulder of the connector, forming a complete thermally broken structure. This structure effectively blocks the heat conduction channel between the interior and exterior, ensuring that the beam maintains excellent thermal insulation performance while possessing load-bearing capacity, thus meeting the thermal performance requirements of energy-efficient building door and window systems.

[0018] 3. Excellent sealing and waterproof performance.

[0019] Waterproof gaskets are installed between the pressure plate and the middle and upper thermal insulation materials to further improve the sealing and watertightness of the connection points and prevent rainwater from seeping in. Sealing grooves are provided on both the upper and lower sides of the pressure plate, with sealing strips embedded in these grooves to contact the upper and lower thermal insulation materials, forming a multi-layered sealing system that ensures stable performance of the doors and windows even under complex climatic conditions.

[0020] 4. High installation precision and good appearance.

[0021] The window frame profiles are fixed to the horizontal beam profiles and internal inserts with screws, ensuring reliable structural connections and even stress distribution, preventing deformation of individual profiles under stress. Adjustable frame components are installed between the window frame profiles and the horizontal beam profiles, allowing for fine-tuning and leveling of the window frame position during installation, improving construction accuracy and assembly efficiency. The overall structure, while ensuring high strength, thermal insulation, and waterproofing, also boasts an aesthetically pleasing and uniform appearance and excellent ease of construction. Its superior overall performance makes it suitable for the installation of various large-span doors and windows. Attached Figure Description

[0027] A waterproof gasket 15 is provided between the pressure plate and the intermediate heat-insulating plastic material 5 and the upper and lower heat-insulating plastic materials 7. The waterproof gasket 15 forms a flexible sealing layer between the pressure plate and the heat-insulating plastic material, which can effectively prevent rainwater or condensation from seeping into the interior of the structure, improve the water tightness and air tightness of the beam connection, and thus enhance the overall waterproof effect.

[0028] Sealing grooves are provided on the upper and lower sides of the pressure plate, opposite to the upper and lower heat-insulating plastic materials 7.
