Description

Technical Field

[0001] This utility model relates to the field of curtain wall connection technology, and in particular to a curtain wall mullion and beam connection structure. Background Technology

[0002] In the splicing of modular glass curtain walls, columns and beams are generally connected using aluminum angle brackets. The conventional insert installation involves cutting an elliptical groove on the back of the beam, and after the beam is installed, pushing the tapered pin on the insert into the corresponding fixing hole on the column, or using a spring-loaded tapered pin. In these methods, the insert is freely inserted into the beam, and its position is not effectively secured. To prevent the insert from sliding within the beam and causing the entire structure to collapse, self-tapping screws are needed to tighten the beam and insert on-site after installation. These installation procedures are overly cumbersome and affect construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a curtain wall column and beam connection structure, which can simplify the installation process of curtain wall columns and beams, thereby reducing the workload of on-site installation and speeding up construction efficiency.

[0005] The curtain wall column-beam connection structure according to the present utility model has at least the following beneficial effects: rapid positioning is achieved through the first connection hole preset on the column and the slidable connector in the beam connection cavity. After the second connection hole on the connector is aligned with the hole on the column, the connecting column is directly inserted by locking the connector through the fixing component to form a rigid connection. This eliminates the cumbersome steps of needing to fix the traditional insert with screws after free insertion, and realizes direct "hole-to-hole" assembly.

[0009] According to some embodiments of the present invention, the fixing component further includes a second blocking member, which is disposed at the end of the connecting member opposite to the first blocking member, and the tension spring is fixedly connected to the connecting member through the second blocking member.

[0012] According to some embodiments of the present invention, the third panel is provided with a clearance groove, which corresponds to the second limiting member and is used to avoid the second limiting member.

[0013] According to some embodiments of the present invention, the first limiting member is a protruding edge provided along the length direction of the crossbeam, and the second limiting member is a groove provided along the length direction of the crossbeam, with the protruding edge and the groove fitting together with a clearance.

[0031] refer to Figures 1 to 5 This embodiment discloses a curtain wall column-beam connection structure.

[0032] like Figures 1 to 5 As shown, the curtain wall mullion-beam connection structure includes a mullion 100, a beam 200, a connector 300, multiple connecting columns 400, and a fixing assembly 500. The mullion 100 has multiple first connecting holes 110, and the beam 200 has a connecting cavity 210. The connector 300 connects to the beam 200 and movably passes through the connecting cavity 210. The connector 300 has multiple second connecting holes 310 along the extension direction of the beam 200, the number of which is the same as the number of the first connecting holes 110. Each first connecting hole 110 corresponds to one second connecting hole 310. The number of connecting columns 400 is the same as the number of the first connecting holes 110. One end of each connecting column 400 passes through a corresponding first connecting hole 110, and the other end passes through a corresponding second connecting hole 310. The fixing component 500 is connected to the connector 300 and the crossbeam 200. The fixing component 500 is configured to fix the connector 300 to the crossbeam 200.

[0033] like Figure 1 and Figure 2 As shown, the column 100 has multiple first connecting holes 110 along the front-rear direction. Correspondingly, the connector 300 has the same number of second connecting holes 310 as the first connecting holes 110, and each first connecting hole 110 corresponds to one second connecting hole 310. The number of connecting posts 400 is the same as the number of first connecting holes 110. A connecting post 400 passes through each corresponding connected first connecting hole 110 and second connecting hole 310, and the connecting post 400 is configured to connect the column 100 and the connector 300. Further, the connector 300 is connected to the crossbeam 200 and is movably inserted into the connecting cavity 210 within the crossbeam 200 via the fixing assembly 500. Thus, as... Figure 3 and Figure 4As shown, rapid positioning is achieved through the first connecting hole 110 pre-set on the column 100 and the sliding connector 300 in the connecting cavity 210 of the beam 200. After the second connecting hole 310 on the connector 300 is aligned with the hole position of the column 100, the connecting column 400, which locks the connector 300 through the fixing component 500, is directly inserted to form a rigid connection. This eliminates the cumbersome steps of traditional inserts that require additional screw fixing after free insertion, and realizes direct "hole-to-hole" assembly. This simplifies the construction process and ensures the stability of the structure through mechanical rigid connection, significantly shortening the curtain wall construction cycle and reducing labor costs.

[0034] In some specific embodiments of this utility model, the connecting post 400 is threadedly connected to the second connecting hole 310.

[0035] In some specific embodiments of this utility model, the connector 300 is tightly embedded in the inner contour of the connecting cavity 210.

[0036] like Figure 2 and Figure 3 As shown, the connecting cavity 210 is a cubic cavity arranged in the front-to-back direction, and the connector 300 is a rectangular grid frame structure extending in the front-to-back direction. The grid frame structure fits perfectly into the cubic cavity, so that the connector 300 is tightly embedded in the inner contour of the connecting cavity 210. This allows it to stably fit the internal structure of the beam 200 during installation, avoiding shaking or displacement. This not only enhances the reliability of the force transmission path and ensures that the load is effectively transferred to the column 100, but also provides better alignment when inserting the connecting column 400, reducing installation errors and improving assembly accuracy.

[0037] In some specific embodiments of this utility model, the connector 300 is provided with a first limiting member 320, and the crossbeam 200 is provided with a second limiting member 220. The first limiting member 320 and the second limiting member 220 cooperate to provide axial guidance during the insertion of the connector 300. Figure 2 and Figure 3 As shown, the first limiting member 320 is a protruding edge along the length of the crossbeam 200, and the second limiting member 220 is a groove along the length of the crossbeam 200. It should be noted that the groove is a groove within the connecting cavity 210. When the groove is recessed into the cavity wall of the connecting cavity 210, it also means that it protrudes from the outer wall of the connector 300. The protruding edge extends along the length of the crossbeam 200, and its clearance fit with the groove not only limits the radial offset of the connector 300 but also provides axial guidance during the insertion of the connector 300, allowing it to slide smoothly during installation and avoiding jamming or misalignment. Construction personnel can quickly and accurately push the connector 300 into the predetermined position, reducing manual adjustment time and thus improving assembly efficiency and positioning accuracy.

[0038] In some specific embodiments of this utility model, the fixing component 500 includes: a first blocking member 510 and a tension spring 520, wherein the first blocking member 510 is connected to the crossbeam 200 and the first blocking member 510 is connected to the connecting member 300, one end of the tension spring 520 is fixedly disposed on the connecting member 300, and the other end is fixedly connected to the first blocking member 510, and the first blocking member 510 is configured to limit the position of the connecting member 300 in the connecting cavity 210 by means of the tension spring 520.

[0039] like Figure 1 and Figure 2 As shown, the first blocking member 510 is disposed at the front end of the connecting member 300, and the front end of the tension spring 520 is fixedly connected to the connecting member 300 and the rear end of the connecting member 300. In some specific embodiments of this utility model, the fixing assembly 500 further includes a second blocking member 530, which is located at the end of the connecting member 300 away from the first blocking member 510, such as... Figure 2 As shown, the tension spring 520 is fixed to the rear end of the connector 300 via the second blocking member 530.

[0040] like Figure 1 As shown, the second blocking member 530 is a stainless steel hanging piece with two through holes.

[0041] In some specific embodiments of this utility model, a receiving hole 330 is provided on the connector 300 along the direction of the crossbeam 200, and a tension spring 520 is axially disposed within the receiving hole 330. A first blocking member 510 and a second blocking member 530 respectively abut against opposite ends of the receiving hole 330. Figure 2 As shown, the connector 300 has a receiving hole 330 along the direction of the crossbeam 200, and a tension spring 520 is built in it and limited by the first blocking member 510 and the second blocking member 530 to form an elastic pre-tightening structure. The axial tension of the tension spring 520 is used to automatically adjust the assembly position of the connector 300, so that it always maintains a tight fit with the crossbeam 200 during the installation process, ensuring connection stability.

[0042] In this specific embodiment, the convex edge is located at the right end of the wall of the receiving hole 330 along the length direction.

[0043] In some specific embodiments of this utility model, the first blocking member 510 includes: a first panel 511, which is connected to the tension spring 520 and spans between the connecting member 300 and the crossbeam 200; a second panel 512, which is disposed at one end of the first panel 511 and forms an angle with the first panel 511, and is connected to the connecting member 300; and a third panel.

[0044] 513, the third panel 513 is located at the end opposite to the first panel 511 and the second panel 512. The third panel 513 and the first panel 511 have an angle. The second panel 512 and the third panel 513 extend in the same direction. The third panel 513 is connected to the crossbeam 200.

[0045] like Figure 1 and Figure 2 As shown, the first blocking member 510 adopts a multi-panel combination structure. The first panel 511 connects the tension spring 520 and spans the connector 300 and the crossbeam 200. The second panel 512 is fixed to the connector 300, and the third panel 513 is connected to the crossbeam 200, providing a stable force support point for the tension spring 520. The angle arrangement of the second and third panels 513 forms a two-way constraint, ensuring that the tension spring 520 always applies force along the axial direction, realizing the precise orientation and pre-tension of the tension spring 520, while preventing the connector 300 from shifting laterally or rotating under dynamic load.

[0046] In some specific embodiments of this utility model, the third panel 513 is provided with a clearance groove 5131, which corresponds to the second limiting member 220 and is used to avoid the second limiting member 220. The clearance groove 5131 provided on the third panel 513 corresponds to the second limiting member 220, i.e., the groove, on the crossbeam 200, so that the first blocking member 510 can accurately avoid the guide structure of the crossbeam 200 during installation, avoiding motion interference. This avoidance design retains the axial guiding function of the second limiting member 220 and ensures a stable connection between the third panel 513 of the first blocking member 510 and the crossbeam 200, so that the tension spring 520 system maintains the mechanical stability of the overall structure while elastically adjusting.

[0047] In some specific embodiments of this utility model, several first connecting holes 110 are pre-drilled on the side wall of the column 100, and a connecting cavity 210 with a guide structure is provided inside the crossbeam 200. The protruding edge provided on the outer side of the connector 300 forms a clearance fit with the groove on the inner wall of the crossbeam 200 to ensure axial guiding accuracy during installation. During installation, the construction personnel only need to push the connector 300 in along the length direction of the crossbeam 200. When the second connecting hole 310 on the connector 300 is completely aligned with the first connecting hole 110 of the column 100, the connecting column 400 can be inserted to achieve a rigid connection. To ensure connection stability, the clearance groove 5131 provided on the third panel 513 of the first blocking member 510 cooperates with the guide groove of the crossbeam 200, which not only ensures the smooth sliding of the connector 300, but also avoids structural interference. Finally, the connecting post 400 in the second connecting hole 310 is inserted into the corresponding first connecting hole 110, and the connecting piece 300 is locked to the crossbeam 200 by the fixing component 500, forming a reliable connection that is both rigid and adjustable.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
