[0028] This utility model provides a construction frame assembly, including templates 1 and connecting devices. Multiple templates 1 are provided, including positioning plates 11. Two adjacent templates 1 abut against each other via the positioning plates 11 and are connected together by the connecting devices. The positioning plates 11 are provided with insertion holes 12. The connecting devices are installed in the corresponding insertion holes 12 on two adjacent templates 1. In this case, the insertion holes 12 only serve a positioning function and do not exert additional force on the positioning plates 11, thus preventing deformation of the positioning plates 11 under the action of the connecting devices and avoiding any impact on the overall connection of the construction frame assembly.

[0029] This utility model discloses a connection device for construction frame formwork. Please refer to [link / reference]. Figures 1 to 5 In some embodiments, the connecting device includes a fastening plate 2, a positioning component, and a connector 22. The fastening plate 2 includes a first lug 21, which is used to connect to other structures, ensuring that the fastening plate 2 itself is not subjected to additional external forces, thus ensuring the strength of the fastening plate 2. The positioning component is connected to the fastening plate 2 and includes a positioning pin 3 and a positioning screw. The positioning screw is connected to the positioning pin 3 and the fastening plate 2 to connect the fastening plate 2 and the positioning pin 3 together. The connector 22 passes through the first lug 21 and abuts against the construction frame template 1. The connector 22 can provide secondary fixation for the template 1 and can also be used to position the construction frame template 1, preventing slippage between two adjacent construction frame templates 1. The positioning component and the fastening plate 2 are respectively located on both sides of the construction frame template 1. At this time, the template 1 of the construction frame is located between the positioning pin 3 and the fastening plate 2, which can prevent the fastening plate 2 and the positioning component from damaging the construction frame template 1 itself.

[0030] In order to prevent the connector 22 from damaging the template 1 when it abuts against the template 1, in some embodiments, the connecting device also includes a pressure plate 23. The pressure plate 23 is rotatably connected to the connector 22 and abuts against the construction frame template 1. This is used to increase the contact area between the connector 22 and the template 1, and to prevent the tail end of the connector 22 from rotating relative to the template 1 when the connector 22 is rotated, which would cause wear on the surface of the template 1.

[0031] Understandably, the side of the pressure plate 23 closest to the template 1 is also provided with anti-slip texture. This can prevent the pressure plate 23 from sliding relative to the template 1 during the contact process, due to the small friction between the pressure plate 23 and the template 1. This would prevent the connecting device from being able to stably fix the template 1, thus affecting the stability of the entire construction frame.

[0032] To facilitate adjustment of the tightness of the connector 22 and the pressure plate 23 to the template 1, in some embodiments, a rotating handle is provided at the end of the connector 22 away from the pressure plate 23. The operator can tighten the connector 22 by rotating the handle without other equipment, and adjust the tightness between the connector 22 and the pressure plate 23 and the template 1. This ensures that the connection between the connector 22 and the template 1 can be adjusted according to actual needs.

[0033] To ensure a more stable connection between the positioning component and the fastening plate 2, in some embodiments, two positioning pins 3 are provided. The two positioning pins 3 are respectively located on both sides of the first lug 21. From both directions of the first lug 21, the fastening plate 2 is stably connected to the positioning plate 1. This prevents the connection effect of the connecting device from being affected if the positioning pin 3 is broken or loosened by external force when the fastening plate 2 and the positioning plate 1 are connected by only one positioning pin 3.

[0034] In some embodiments, the positioning component further includes a connecting shaft 31, with its two ends connected to two positioning pins 3 respectively. On the one hand, it can play a certain positioning role in the connection between the positioning pins 3 and the fastening plate 2, preventing the positioning pins 3 from shifting from the fastening plate 2 during connection, thereby affecting the connection effect of the connecting device. On the other hand, by connecting the two positioning pins 3 together through the connecting shaft 31, the strength of the positioning pins 3 is further enhanced, and the positioning component is prevented from being damaged by external force collision when connecting the fastening plate 2, thus affecting the connection effect of the entire connecting device on the construction frame.

[0035] Furthermore, in some embodiments, the connecting shaft 31 and the two positioning pins 3 are arranged in a U-shape, which ensures that while the strength of the positioning pins 3 is enhanced by the connecting shaft 31, the arrangement of the connecting shaft 31 will not affect the arrangement of various structures on the entire connecting device, nor will it affect the connection effect between the connecting device and the template 1.

[0036] Understandably, in some embodiments, the connecting shaft 31 and the positioning pin 3 are integrally formed, which ensures the strength of the connecting shaft 31 and the positioning pin 3 and prevents the connecting shaft 31 from breaking off due to external force collision when the positioning pin 3 connects the fastening plate 2 and the template 1, thus affecting the connection effect of the entire connecting device on the construction frame.

[0037] In order to ensure that the connecting device can be stably connected to both ends of the positioning plate 11, in some embodiments, the fastening plate 2 further includes two symmetrically arranged second ears 24 on the side away from the first ear 21. The two second ears 24 are connected by a fixing bolt 25 to ensure that the outer end of the positioning plate 11 can also be supported when the two templates 1 are connected, thereby further ensuring the stability of the connection of the connecting device.

[0038] In some embodiments, two first lugs 21 and positioning components are provided, and are respectively symmetrically arranged at both ends of the same plate surface of the fastening plate 2, so as to ensure that both ends of the fastening plate 2 can be connected and fixed by the positioning pins 3, and to avoid the deformation of the fastening plate 2 when the template 1 is subjected to external force due to uneven force between the fastening plate 2 and the positioning pins 3, thereby affecting the connection effect of the entire connection device and the strength of the construction frame.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
