Description

Technical Field

[0001] This utility model relates to door and window curtain wall engineering, and particularly to the design and construction system of curtain walls with large volume and structural walls at the ends of frame beams, specifically a prefabricated door and window curtain wall structure. Background Technology

[0002] Doors and windows, as an important component of building curtain wall appearance, serve to enhance the facade effect and are used in most building curtain walls. For large-scale flat door and window systems, the installation process often presents challenges such as significant installation errors, potential leaks, and safety hazards due to the on-site installation of individual components. This is particularly true for large-scale curtain wall designs and systems with structural walls at the ends of frame beams, which not only suffer from the aforementioned errors, waterproofing, and safety issues, but also result in low on-site installation efficiency and are time-consuming and labor-intensive. Furthermore, conventional safety door and window curtain walls cannot be installed continuously as single units due to the walls on either side of the doors and windows, making it difficult to achieve a smooth exterior facade after installation. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated door and window curtain wall structure to solve problems such as excessive installation errors, water leakage risks, safety hazards, and uneven facade caused by on-site installation of loose parts during the installation of large-scale curtain wall door and window systems with structural wall at the end of the frame beam.

[0004] The objective of this utility model is achieved through the following technical solution: A prefabricated door and window curtain wall structure includes a door and window curtain wall integrally installed on the outside of a wall and embedded plates respectively embedded in the top and bottom of the door and window; the door and window curtain wall encloses the wall on the inside; the door and window curtain wall includes a curtain wall frame and glass installed on the curtain wall frame, the curtain wall frame is composed of multiple prefabricated frame groups assembled sequentially; each frame group is an integral closed component, which is formed by vertically arranged side columns, frame sides and horizontally arranged top beams and bottom beams to form a rectangular frame, and within the rectangular frame, it is further divided into multiple small frames for placing glass by at least one vertical central column and a horizontal central beam; the side columns of each frame group are connected to the frame sides of the next frame group by pan head self-tapping screws, and the outer side of the side column that connects to the frame side is recessed inward to form a vertical through joint, the joint being filled with sealant; the side columns and central columns of each frame group are connected and fixed to the upper and lower embedded plates by adapters and machine screws.

[0005] Furthermore, the outer cross-section of the side column is set as a stepped shape, which includes at least two consecutive grooves arranged one in front of the other. The rear groove is used to accommodate the frame of the next set of frames, and the front groove is the joint.

[0006] Furthermore, the side columns and frame are connected to the top and bottom crossbeams via angle aluminum. The parts of the angle aluminum connected to the side columns or frame are connected by machine screws, and the parts of the angle aluminum connected to the top or bottom crossbeams are connected by pan head self-tapping screws.

[0007] Furthermore, the central column is fixedly connected to the top and bottom crossbeams using pan head self-tapping screws.

[0008] Furthermore, the middle crossbeam is connected and fixed to the columns, middle columns, and frame using π-shaped connectors; the part of the connector connected to the side columns, middle columns, or frame is connected by machine screws, and the part of the connector connected to the middle crossbeam is connected by pan head self-tapping screws (9).

[0009] Furthermore, the joints between the side columns, middle columns, and frame and the top, middle, and bottom crossbeams are all sealed with adhesive.

[0010] Furthermore, the width of the seam is 1~1.5cm.

[0011] The advantages and beneficial effects of this utility model are: This utility model of door and window curtain wall is composed of multiple assembled frames. Each frame is an integral closed component, which can be hoisted on site after being processed in the factory. The door and window curtain wall of this utility model encloses the wall inside, and a small joint for applying sealant is also designed separately.

[0012] On-site hoisting of prefabricated frames can greatly reduce the amount of on-site keel installation, enable rapid installation, meet the large adjustment requirements of on-site installation, and improve installation efficiency and construction safety.

[0013] By assembling prefabricated frames in the factory, large-scale production is reduced to smaller units, and the quality of the frames is controlled at the unit level. This ensures the flatness of the frame beams and columns, minimizing misalignment errors. During on-site installation, only the positioning of each frame needs to be corrected, and the sealing of the frames should be controlled between adjacent frames. This reduces the amount of sealant needed on-site and improves the overall waterproof performance of the system.

[0014] The door and window curtain wall encloses the wall on the inside, and small seams are designed at the splicing of the frame to solve the wall problem, so that the segmented door and window system can be connected, realize continuous installation, and improve the facade effect and waterproofing of the curtain wall system.

[0018] Example 1: like Figures 1-7 As shown, a prefabricated door and window curtain wall structure includes a door and window curtain wall integrally installed on the outside of a wall 14, and embedded plates 12 respectively embedded in the top and bottom of the doors and windows; the door and window curtain wall encloses the wall 14 on the inside; the door and window curtain wall includes a curtain wall frame and glass installed on the curtain wall frame, the curtain wall frame being composed of multiple prefabricated frame sections sequentially spliced ​​together; in this embodiment, each frame section is approximately 3.3m long and approximately 3.2m wide. The columns, frames, and beams in the frame section are all made of aluminum alloy profiles.

[0019] Each frame is an integral closed component, consisting of vertically arranged side columns 1, frame 3, and horizontally arranged top beam 4 and bottom beam 6 forming a rectangular frame. Within the rectangular frame, a vertical central column 2 and two horizontal central beams 5 further divide it into multiple smaller frames for placing glass. The side columns 1 of each frame are connected to the frame 3 of the next frame by pan-head self-tapping screws 9. The outer side of the end where the side column 1 connects to the frame 3 is recessed inward to form a vertical through joint 13, which is filled with sealant. The width of the joint 13 is 1~1.5cm. This width satisfies the sealing requirements, is the preferred width for the aesthetic appearance of the facade, and facilitates construction. A width that is too large or too small will not meet the above requirements.

[0020] The side columns 1 and center columns 2 of each frame are connected and fixed to the upper and lower embedded plates 12 via adapters 11 and machine screws 10. In this embodiment, the machine screws are M6x16 machine screws, and the adapters 11 are 50*50*6 hot-dip galvanized angle steel. The pan head self-tapping screws in this embodiment are ST4.8, ST4.2, or ST6.3 pan head self-tapping screws. In this embodiment, the outer cross-section of the side column 1 is set in a stepped shape, which includes at least two consecutive grooves arranged one behind the other. The rear groove is used to accommodate the frame 3 of the next set of frames, and the front groove is the joint 13. This stepped design further ensures the tightness of the connection between the frames and the waterproof performance.

[0021] For each group box: Side columns 1 and frame 3 are connected to top beam 4 and bottom beam 6 via angle aluminum 8. The connection between angle aluminum 8 and side columns 1 or frame 3 is achieved using machine screws 10, while the connection between angle aluminum 8 and top beam 4 or bottom beam 6 is achieved using pan head self-tapping screws 9. Middle column 2 is fixedly connected to top beam 4 and bottom beam 6 using pan head self-tapping screws 9. Middle beam 5 is connected and fixed to columns 1, middle columns 2, and frame 3 using π-shaped connectors 7. The connection between connectors 7 and side columns 1, middle columns 2, or frame 3 is achieved using machine screws 10, while the connection between connectors 7 and middle beam 5 is achieved using pan head self-tapping screws 9. All joints between side columns 1, middle columns 2, frame 3 and top beam 4, middle beam 5, and bottom beam 6 are sealed with adhesive. In other words, all beam and column profile joints are sealed with adhesive, and adhesive strips run along the entire length of all beams and columns. The adhesive used is weather-resistant sealant.

[0022] On-site installation: Prefabricated construction is adopted on-site. The assembled frames are hoisted, and the columns 1 and center columns 2 are connected and fixed to the embedded plates 12 via adapters 11 and machine screws 10. Adjacent frames are connected and fixed to the columns 1 via frame 3 using pan-head self-tapping screws 9. The joints 13 at the frame splicing points are sealed with adhesive. This utility model completely encloses the wall within the curtain wall structure, solving the problem of connecting the frame systems when there are walls on both sides of the doors and windows. It optimizes the assembly process from loose components to prefabricated construction, reducing on-site installation and adhesive application.

[0023] In this embodiment, the bulk door and window curtain wall frames are assembled into individual units in the factory and then hoisted onto the site, achieving continuous window frame installation. This solves the problem of not being able to install individual units on-site. Conventional doors and windows are typically supported by walls on both sides; the prefabricated design with small seams solves this problem, resulting in a better facade appearance. Factory assembly minimizes the size of the frame assembly, controlling quality at the unit level and ensuring the flatness of the frame beams and columns, minimizing misalignment errors. During on-site installation, only the positioning of each frame assembly needs to be corrected, and the sealing of the frames should be controlled between adjacent frames. This reduces the amount of sealant needed on-site and improves the overall waterproofing performance of the system.

[0024] Finally, it should be noted that the above is only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the preferred arrangement, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model.
