Description

Technical Field

[0001] The utility model relates to the technical field of aluminum formwork, in particular to a fastening device for a building aluminum formwork. Background Art

[0002] Aluminum alloy formwork, a new formwork technology, is gradually impressing the entire construction market with its high quality, high turnover, and simple and fast installation. During assembly, aluminum alloy formwork is typically assembled using bolts. However, bolt assembly can be prone to thread breakage due to the swaying of the aluminum alloy formwork, affecting the stability of the connection between the assembled aluminum alloy formwork.

[0003] The Chinese utility model patent with patent application number 202223425078.7 provides a fastening device for building aluminum formwork. By connecting the pull frame, the fastening pull plates on both sides are pulled to slide toward the middle of the inner cavity of the guide sleeve, so that the limit blocks on the fastening pull plates on both sides can be in contact with the side walls of the building aluminum formwork, and the building aluminum formwork on both sides are fastened into a whole. The fastening pull plates can limit the shaking phenomenon between the two adjacent building aluminum formworks, and relative to the bolt connection, can ensure the stability of the fastening of the two building aluminum formworks.

[0004] However, during the use of the above-mentioned equipment, it was found that although the fastening assembly has replaced the bolt connection to a certain extent, the rotation of the adjusting screw still requires operation by construction workers. In large-scale construction projects, multiple fastening assemblies need to be operated. Rotating the screws one by one will increase the time cost of installing the assembly. At the same time, construction workers need to pay attention to the installation direction of the aluminum formwork, which will further affect the installation efficiency of the aluminum formwork. Utility Model Content

At the same time, construction workers need to pay attention to the installation direction of the aluminum formwork, which will further affect the installation efficiency of the aluminum formwork.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a building aluminum formwork fastening device, including a plate, a connecting hole is opened on the peripheral side of the plate, symmetrical limiting holes are provided on both sides of the connecting hole, a connecting member is installed on the connecting hole, the connecting member includes a connecting block, the connecting block is adapted to the connecting hole, a rotating shaft is fixedly installed on one end of the connecting block, a limiting block is rotatably connected to the rotating shaft, a mounting block is fixedly connected to the end of the connecting block away from the limiting block, the mounting block is arranged perpendicular to the connecting block, and a limiting assembly is installed on the limiting block.

[0007] Preferably, mounting rods are fixedly mounted on both ends of the mounting block, and the mounting rods are adapted to the limiting holes.

[0012] The utility model provides a fastening device for building aluminum formwork, which has the following beneficial effects:

[0013] (1) The utility model sets a connecting piece, sets the connecting piece in the connecting hole between two adjacent aluminum templates, and uses a limit block that is rotatably set at one end of the connecting piece to rotate it to be perpendicular to the connecting hole, so that the limit block and the installation block can simultaneously limit the aluminum template, thereby realizing rapid connection and installation between two adjacent aluminum templates.

[0014] (2) The utility model sets a limit assembly, and uses the spring in the limit assembly to push the limit rod into the limit hole, thereby limiting the limit block and avoiding the problem of the limit block rotating, which affects the connection effect of the aluminum template.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-Figure 5 A fastening device for an aluminum formwork for construction includes a plate 1. A connecting hole 11 is formed on the circumferential side of the plate 1. Symmetrical limiting holes 12 are provided on both sides of the connecting hole 11. A connecting member 2 is installed on the connecting hole 11. The connecting member 2 includes a connecting block 21. The connecting block 21 is adapted to the connecting hole 11. A rotating shaft 25 is fixedly installed on one end of the connecting block 21. A limiting block 24 is rotatably connected to the rotating shaft 25. A mounting block 22 is fixedly connected to the end of the connecting block 21 that is away from the limiting block 24. The mounting block 22 is arranged perpendicular to the connecting block 21. A limiting assembly 3 is installed on the limiting block 24.

[0025] Mounting rods 23 are fixedly mounted on both ends of the mounting block 22 , and the mounting rods 23 are adapted to the limiting holes 12 .

[0026] Specifically, when performing the combined connection of the aluminum formwork, the two plates 1 are fitted together so that the connecting holes 11 and the limiting holes 12 on the plates 1 correspond to each other. The construction personnel use the connecting piece 2 to pass the end of the connecting piece 2 with the limiting block 24 through the connecting hole 11. The connecting hole 11 is adapted to the connecting block 21 to ensure that the connection between the two adjacent plates 1 remains stable. The connecting block 21 is tightly fitted with the plates 1, which increases the firmness of the connection and reduces the possibility of loosening or displacement during use. At the same time, the mounting block 22 vertically arranged at one end of the connecting block 21 can fit with the inner wall of the plate 1, and the mounting rod 23 on the mounting block 22 can enter the corresponding limiting hole 12.

[0027] After the limit block 24 passes through the connecting hole 11, the construction workers rotate the limit block 24 so that the limit block 24 is perpendicular to the connecting hole 11, which can effectively prevent the connecting block 21 from accidentally falling out of the connecting hole 11, and at the same time can further restrict the movement of the plate 1. By passing one end of the connecting block 21 with the limit block 24 through the connecting hole 11, the operation is simple and quick, and the construction workers can quickly complete the initial connection steps. Compared with the traditional complex connection method, it greatly saves connection time and improves the efficiency of the aluminum formwork assembly.

[0028] Example 2:

[0029] To avoid the problem of accidental rotation of the stop block 24, please refer to Figure 1-Figure 5 On the basis of Example 1, the limiting assembly 3 includes a handle 31, and a gripping groove 32 is provided on both sides of the handle 31. The inner wall of the gripping groove 32 is arc-shaped, and both ends of the handle 31 are fixedly connected to a connecting rod 33;

[0030] The handle 31 is connected to the limiting rod 34 via a connecting rod 33, and the limiting rod 34 is adapted to the limiting hole 12;

[0031] The connecting rod 33 and the limiting rod 34 are both slidably arranged in the sliding groove 36, and the sliding groove 36 is provided at both ends of the limiting block 24;

[0032] A spring 35 is connected to the inner wall of the sliding groove 36 , and one end of the limiting rod 34 is connected to the spring 35 .

[0033] Specifically, in a normal state, the state of the connector 2 is as shown in the attached figure. Figure 5 As shown, the limit rod 34 is restricted by the connecting block 21 and retracted in the slide groove 36, so that the limit rod 34 squeezes the spring 35, so that the spring 35 is in a compressed state. When the limit block 24 is rotated, the construction worker holds the handle 31 to control the limit block 24 to rotate. During this process, the spring 35 is always in a compressed state. When the limit block 24 is rotated to be perpendicular to the connecting hole 11, the limit rod 34 corresponds to the limit hole 12. The construction worker releases the handle 31, so that the spring 35 loses the external force restriction and then returns to its original state, pushing the limit rod 34 into the corresponding limit hole 12. By utilizing the adaptation of the limit rod 34 and the limit hole 12, the limit hole 12 restricts the limit rod 34 and the limit block 24 to prevent the limit block 24 from rotating accidentally.

[0034] The inner walls of the gripping grooves 32 on both sides of the gripping handle 31 are arc-shaped, which conforms to the ergonomic design, increases the comfort of gripping, reduces hand fatigue during operation, and facilitates construction personnel to control the gripping handle 31 to avoid slipping. The slide groove 36 provides a sliding track for the limit rod 34 and the connecting rod 33 to ensure that they can move in the correct direction. The slide groove 36 matches the limit rod 34 to ensure the smoothness and stability of the sliding of the limit rod 34, so that the limit rod 34 can accurately enter the limit hole 12.

[0035] Working principle: When the equipment is in use, the two building aluminum formwork plates 1 that need to be connected are fitted together so that the connecting holes 11 and the limiting holes 12 on the plates 1 correspond to each other, ensuring that the position of the plates 1 is accurate and avoiding deviations during the installation process. The construction personnel use the connector 2 to pass the end of the connector 2 with the limiting block 24 through the connecting holes 11 where the two plates 1 fit together. The adaptability of the connecting holes 11 and the connecting block 21 is utilized to ensure the stable connection of the two adjacent plates 1. After the limiting block 24 passes through the connecting hole 11, the construction personnel hold the handle 31 to control the limiting block 24 to rotate. When the limiting block 24 rotates to be perpendicular to the connecting hole 11, the limiting rod 34 corresponds to the limiting hole 12.

[0036] At this time, the construction worker releases the grip 31, so that the spring 35 loses the external force restriction and then returns to its original state, pushing the limit rod 34 into the corresponding limit hole 12. By utilizing the adaptability of the limit rod 34 and the limit hole 12, the limit hole 12 restricts the limit rod 34 and the limit block 24, preventing the limit block 24 from accidentally rotating, so that when connecting, the limit block 24 always remains in a perpendicular state to the connecting hole 11, and can then be combined with the mounting block 22 to restrict the connecting block 21, preventing the connecting block 21 from detaching from the connecting hole 11, thereby affecting the connection effect between the two plates 1;

[0037] The entire installation process mainly includes several simple steps such as aligning the plate 1, inserting the connecting piece 2, rotating the limit block 24 and inserting the limit rod 34. Compared with the traditional complex connection method, it reduces the cumbersome operation process, greatly saves installation time, and thus improves the efficiency of the aluminum formwork combination connection.
