Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated curtain walls, and more specifically, to an insertion - type self - locking connection device for prefabricated curtain walls. Background Technique

[0002] The prefabricated curtain wall is the external wall enclosure of a building, which is a lightweight wall with a decorative effect commonly used in modern large - scale and high - rise buildings. It is mainly composed of a structural framework and inlaid plates, and is a building enclosure structure that does not bear the load and action of the main structure. In the installation process of the existing dry - hanging method for prefabricated curtain walls, the hanging parts on the back side of the curtain wall panel are usually hung on the main curtain wall keel from top to bottom, and then tools are used to sequentially turn each fastener for installation and locking. This makes the overall installation operation rather cumbersome. And generally, the curtain wall panels need to be continuously paved from bottom to top and from one side to the other in sequence to complete the installation, making it difficult to reserve a hole space for installing a single curtain wall panel, which brings inconvenience to the curtain wall installation construction operation. In view of this, we propose an insertion - type self - locking connection device for prefabricated curtain walls. Content of the Utility Model

[0024] Embodiment 1:

[0025] As Figures 1 to 3 shown, the present utility model provides an insert type self-locking connection device for an assembled curtain wall, including an L-shaped connecting plate 1 and a fixed box 2. A wedge-shaped guiding surface 101 is provided on one end side of the L-shaped connecting plate 1, an elongated circular hole 102 is provided on the other end surface of the L-shaped connecting plate 1, a hollow opening 201 is transversely provided on the side of the fixed box 2, and the L-shaped connecting plate 1 is adapted to the hollow opening 201, so that the L-shaped connecting plate 1 can be inserted into the hollow opening 201 on the fixed box 2 in cooperation. A self-locking component 3 for locking and fastening the L-shaped connecting plate 1 is provided on the fixed box 2.

[0026] Among them, asFigure 1 and Figure 2 As shown in Figure 2 , the self-locking component 3 includes an assembly fixed shaft 4 and a check pin member 5. The check pin member 5 is rotatably mounted on the fixed box 2 through the assembly fixed shaft 4. A limit through hole 202 for limiting the check pin member 5 is provided on the fixed box 2. Fish-scale reverse teeth I103 are provided on both the upper and lower sides of the middle part of the L-shaped connecting plate 1. The check pin member 5 is adapted to the fish-scale reverse teeth I103.

[0027] Among them, as Figure 2 shown, the check pin member 5 includes an upper check pin 501 and a lower check pin 502 which are distributed up and down. Transmission inclined surfaces 503 are provided on the bottom side of the upper check pin 501 and the top side of the lower check pin 502. When the L-shaped connecting plate 1 is inserted into the hollow opening 201 on the fixed box 2, the wedge-shaped guiding surface 101 on the L-shaped connecting plate 1 abuts against the transmission inclined surface 503, which can drive the upper check pin 501 and the lower check pin 502 to rotate to one side. When the fish-scale reverse teeth I103 move to the set position along with the L-shaped connecting plate 1, the gravity can drive the upper check pin 501 and the lower check pin 502 to rotate back to the other side by themselves.

[0028] Among them, as Figure 2 shown, the number of the upper check pins 501 and the lower check pins 502 is two each. The two upper check pins 501 and the two lower check pins 502 are distributed at intervals front and back. The limit through hole 202 can limit the upper check pin 501 and the lower check pin 502 after they rotate back by themselves. One upper check pin 501 and the lower check pin 502 cooperate with the fish-scale reverse teeth I103 to prevent the L-shaped connecting plate 1 from moving backward, and the other upper check pin 501 and the lower check pin 502 cooperate with the fish-scale reverse teeth I103 to prevent the L-shaped connecting plate 1 from moving forward, so that the self-locking component 3 on the fixed box 2 locks the L-shaped connecting plate 1 naturally.

[0029] Embodiment 2:

[0030] As Figures 4 to 6 shown, the present utility model provides an insert type self-locking connection device for an assembled curtain wall, which includes an L-shaped connecting plate 1 and a fixed box 2. A wedge-shaped guiding surface 101 is provided on one end side of the L-shaped connecting plate 1. An oblong hole 102 is provided on the other surface of the L-shaped connecting plate 1. A hollow opening 201 is provided horizontally on the side of the fixed box 2. The L-shaped connecting plate 1 is adapted to the hollow opening 201, so that the L-shaped connecting plate 1 can be inserted into the hollow opening 201 on the fixed box 2 in cooperation. A self-locking component 3 for locking and fastening the L-shaped connecting plate 1 is provided on the fixed box 2.

[0031] The difference from Embodiment 1 is that, as Figure 4 and Figure 5As shown in the figure, the self-locking component 3 includes a check stop 6 and two limit screws 7. A limit sliding opening 203 is provided at a position on the fixed box 2 corresponding to the check stop 6. The check stop 6 is slidably connected to the inner side of the limit sliding opening 203. The two limit screws 7 are respectively threadedly connected to both ends of the check stop 6. A fish-scale reverse tooth II 104 is provided on the upper side of the middle part of the L-shaped connecting plate 1. The check stop 6 is adapted to the fish-scale reverse tooth II 104.

[0032] Among them, as Figure 4 shown, a transmission arc surface 601 is provided on the bottom side of the check stop 6. When the L-shaped connecting plate 1 is inserted into the hollow opening 201 on the fixed box 2, the wedge-shaped guiding surface 101 on the L-shaped connecting plate 1 abuts against the transmission arc surface 601, which can drive the check stop 6 to slide upward along the limit sliding opening 203. When the fish-scale reverse tooth II 104 moves to the set position along with the L-shaped connecting plate 1, the gravity can drive the check stop 6 to slide downward and return by itself.

[0033] Among them, as Figure 4 shown, the number of check stops 6 is two. The two check stops 6 are distributed at intervals front and back. The limit sliding opening 203 can be used to limit the check stop 6 after it slides back by itself. One check stop 6 cooperates with the fish-scale reverse tooth II 104 to prevent the L-shaped connecting plate 1 from moving backward, and the other check stop 6 cooperates with the fish-scale reverse tooth II 104 to prevent the L-shaped connecting plate 1 from moving forward. Thus, the self-locking component 3 on the fixed box 2 locks the L-shaped connecting plate 1 naturally.

[0034] Among them, as Figure 5 shown, a cutout groove 204 is provided at a position on the fixed box 2 corresponding to the limit sliding opening 203. The end cap part of the limit screw 7 is located in the cutout groove 204.

[0035] The working principle of the present utility model:

[0036] When installing curtain wall components, measure, lay out lines and fixedly weld the fixed box on the main curtain wall keel. Prepare the curtain wall panel according to the drawing requirements. Check and verify the position of the back bolts for installation on the back side of the curtain wall panel. Install the L-shaped connecting plate 1 on the back bolts of the curtain wall panel. The number of L-shaped connecting plates 1 is four. The L-shaped connecting plates 1 are distributed at intervals at each end corner on the back side of the curtain wall panel to ensure the stable installation and connection effect of the curtain wall panel. After determining the position, tighten the nuts for fixation. Use a hoisting machine to lift the curtain wall panel with the L-shaped connecting plate 1 installed to the position to be installed, and then manually fine-tune it to the proper position. Slowly push the L-shaped connecting plate 1 so that the L-shaped connecting plate 1 is inserted into the fixed box 2, and then evenly push the curtain wall panel to the appropriate position. After installation in place, use the self-locking component 3 on the fixed box 2 to lock the L-shaped connecting plate 1 naturally, so that the curtain wall panel cannot move back, thereby enabling the horizontal insertion and quick installation of the curtain wall components.
