Description

Technical Field

[0001] This utility model relates to the technical field of building curtain walls, and in particular to a building curtain wall connection structure. Background Technology

[0002] In the field of modern architecture, building curtain walls, as an important component of building facades, not only serve the functions of decorating buildings and isolating them from the external environment, but also need to meet multiple technical requirements such as structural safety, seismic performance, and ease of installation. The connection structure between the curtain wall and the main building structure is a key link in realizing the function of the curtain wall, and its design rationality directly affects the overall stability and service life of the curtain wall system.

[0003] In traditional building curtain wall connection structures, embedded parts are mostly made of a single steel material and connected to the main structure concrete through anchor claws. However, on the one hand, the bonding performance between the embedded parts and the main structure concrete needs to be improved. The difference in elastic modulus between the single steel material and concrete is relatively large, which can easily lead to stress concentration under temperature changes, seismic loads, etc., resulting in cracks at the interface between the embedded parts and concrete, affecting the connection strength. On the other hand, the adjustment performance of the connection structure is insufficient. The fit gap between traditional connectors and embedded parts is fixed, and the connection with curtain wall columns and beams is mostly rigid. It is difficult to make fine adjustments to the plane position and verticality of the curtain wall during installation, which increases the construction difficulty and makes it difficult to adapt to the displacement requirements caused by slight settlement or deformation of the building structure. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this utility model proposes a building curtain wall connection structure, which enhances the connection and seismic resistance with the main structure through composite embedded parts, and achieves flexible adjustment during installation and use with the help of adjustable connectors, thereby improving the stability, safety and construction convenience of the curtain wall system.

[0006] To achieve the above objectives, this utility model proposes a building curtain wall connection structure, including a composite embedded part and an adjustable connector. The composite embedded part includes a steel body and an outer elastic composite part. One side of the steel body is provided with multiple anchor claws that penetrate into the concrete of the main structure, and the other side of the steel body is provided with a groove that cooperates with the adjustable connector. The adjustable connector includes an upper part and a lower part. The upper part cooperates with the groove of the steel body, and the lower part is connected to the curtain wall column or beam through an elongated hole and connecting bolts. The upper part and the lower part are connected by fastening bolts.

[0007] The building curtain wall connection structure of this utility model enhances the connection and seismic resistance with the main structure through composite embedded parts, and realizes flexible adjustment during installation and use with the help of adjustable connectors, thereby improving the stability, safety and construction convenience of the curtain wall system.

[0008] In addition, the building curtain wall connection structure proposed in this application may also have the following additional technical features:

[0009] Specifically, the anchor claw is L-shaped.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The building curtain wall connection structure of this utility model embodiment will be described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the building curtain wall connection structure of this utility model embodiment may include composite embedded parts and adjustable connectors.

[0023] The composite embedded component includes a steel body 1 and an outer elastic composite component 2. The steel body 1 has multiple anchor claws 3 that penetrate into the concrete of the main structure on one side, and a slot 6 that cooperates with the adjustable connector on the other side. The adjustable connector includes an upper part 4 and a lower part 5. The upper part 4 cooperates with the slot 6 of the steel body 1, and the lower part 5 is connected to the columns or beams of the curtain wall through an elongated hole 7 and connecting bolts 8. The upper part 4 and the lower part 5 are connected by fastening bolts 9.

[0024] In one embodiment of this utility model, the connection between the steel body 1 and the anchor claw 3 is reinforced by welding.

[0025] In one embodiment of this utility model, the outer elastic composite 2 is wrapped around the outer layer of the steel body 1 by a molding process. The elastic composite 2 can be made of natural rubber composite, neoprene rubber composite, ethylene propylene diene monomer (EPDM) rubber composite, etc.

[0026] Specifically, the composite embedded part, as the basic load-bearing component connecting the structure and the main structure, includes a steel body 1 and an outer elastic composite part 2. The steel body 1 is formed by integral forging to ensure uniform structural strength. The outer elastic composite part 2 is tightly wrapped around the outer surface of the steel body 1 by molding process, forming a composite structure of "rigid core + elastic outer layer". Multiple anchor claws 3 are integrally processed on one side of the steel body 1. The anchor claws 3 are evenly distributed along the length of the steel body 1, and their ends penetrate into the concrete of the main structure to form mechanical anchoring. A long strip-shaped groove 6 is processed on the other side of the steel body 1. The groove 6 extends along the length of the steel body 1 and has a U-shaped cross-section.

[0027] The adjustable connector serves as an intermediate component connecting the curtain wall and the embedded parts. It includes an upper part 4 and a lower part 5 that cooperate with each other. The upper part 4 adopts a T-shaped structure that is compatible with the slot 6. Its horizontal part is embedded in the slot 6 to form a sliding fit. The lower part 5 is a flat plate structure. One end is connected to the upper part 4 by a fastening bolt 9, and the other end is machined with an elongated hole 7. It is detachably connected to the curtain wall's columns or beams by a connecting bolt 8 that passes through the elongated hole 7.

[0028] In one embodiment of this utility model, such as Figure 1 As shown, anchor claw 3 is L-shaped.

[0029] Specifically, the anchor claw 3 adopts an L-shaped structure design. The L-shaped structure enables the anchor claw 3 to form a "hooking" effect in the concrete, which can effectively increase the anchoring force compared with a straight anchor claw.

[0030] In one embodiment of this utility model, such as Figure 4 As shown, the width of the slot 6 is adapted to the corresponding mating part of the upper part 4 and an adjustment gap is reserved.

[0031] Specifically, the width of the slot 6 is 2-5mm larger than the width of the horizontal part of the upper part 4 of the adjustable connector. This gap forms a horizontal adjustment space. A uniform gap is reserved between the two sides of the horizontal part of the upper part 4 and the inner wall of the slot 6 to ensure that the upper part 4 can slide smoothly along the length of the slot 6 and achieve horizontal adjustment within a range of ±10mm. The opening of the slot 6 is provided with an inwardly protruding limiting edge to prevent the upper part 4 from disengaging from the slot 6 and improve connection safety.

[0032] In one embodiment of this utility model, such as Figure 3 As shown, the size of the elongated hole 7 in the lower part 5 is adapted to the connecting bolt 8 and an adjustment gap is reserved.

[0033] Specifically, the width of the elongated hole 7 in the lower part 5 is 2-3 mm larger than the nominal diameter of the connecting bolt 8, forming a vertical adjustment space. After the connecting bolt 8 passes through the elongated hole 7, it is threaded to the curtain wall column or beam. When the bolt is not fully tightened, the lower part 5 can move up and down along the length of the elongated hole 7 to achieve vertical adjustment within a range of ±15 mm. The two ends of the elongated hole 7 adopt a rounded transition design to avoid structural damage caused by stress concentration.

[0034] Specifically, the composite embedded part penetrates into the main structure concrete through the L-shaped anchor claw 3, forming a reliable mechanical anchor after the concrete hardens, and transfers the curtain wall load to the main structure through the steel main body 1. The outer elastic composite part 2 can absorb the relative deformation between the main structure and the curtain wall, and reduce the additional internal forces generated by temperature stress and seismic action.

[0035] The adjustable connector's upper part 4 and slot 6 are fitted together to allow for fine-tuning of the horizontal position, facilitating compensation for positional deviations during the installation of embedded parts. The lower part 5's elongated hole 7 engages with the connecting bolt 8 to achieve vertical height adjustment, ensuring the flatness of the curtain wall installation. During adjustment, the relative positions of the upper part 4 and lower part 5 can be adjusted by loosening the fastening bolt 9. After completing three-dimensional positioning, all bolts are tightened to achieve fixation.

[0036] The wind load and self-weight borne by the curtain wall are transmitted to the lower part 5 of the adjustable connector through the connecting bolts 8, then to the upper part 4 through the fastening bolts 9, and then to the steel body 1 through the slots 6. Finally, the force is transmitted to the main concrete structure through the anchor claws 3, forming a complete force transmission path.

[0037] The outer elastic composite component 2 undergoes elastic deformation under stress, which can absorb structural vibration energy and stress generated by temperature deformation, reduce rigid collisions between the curtain wall and the main structure, and improve the seismic performance and temperature adaptability of the system.

[0038] In summary, the building curtain wall connection structure of this utility model embodiment enhances the connection and seismic resistance with the main structure through composite embedded parts, and achieves flexible adjustment during installation and use with the help of adjustable connectors, thereby improving the stability, safety and construction convenience of the curtain wall system.
