Description

Technical Field

[0002] In modern construction, the use of formwork is an important means to ensure the accuracy of shape and size when pouring concrete structures. Among them, aluminum alloy formwork is widely used due to its advantages such as light weight, corrosion resistance, and easy assembly. Existing aluminum alloy formworks usually use a bayonet method to achieve anchoring. The structural strength of this anchoring method is poor. When subjected to force in use, the anchored aluminum alloy formwork will become loose, and the subsequent disassembly of the aluminum alloy formwork will increase the difficulty, which cannot meet the use requirements.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN215760426U proposes an aluminum alloy formwork anchoring device, which embeds a threaded sleeve inside the building wall, passes the threaded anchor rod through the clamping pad and the aluminum alloy formwork, connects the threaded anchor rod and the threaded sleeve into an integrated structure with the help of a threaded connector, installs a locking nut on the threaded anchor rod and rotates the locking nut with the help of a wrench, and the rotating locking nut pushes the clamping pad and the aluminum alloy formwork. The aluminum alloy formwork can be clamped and fixed on the building wall with the help of the extrusion force between the clamping pad and the aluminum alloy formwork, thereby completing the anchoring of the aluminum alloy formwork.

[0004] However, although the above-mentioned aluminum alloy formwork anchoring device can connect the threaded anchor rod and the threaded sleeve into an integrated structure through a threaded connector, and then fix the aluminum alloy formwork on the threaded anchor rod through a locking nut threadedly connected to the threaded anchor rod, when the aluminum alloy formwork anchoring device connects the threaded anchor rod and the threaded sleeve through a threaded connector, it is inevitable that the threaded connector and the threaded sleeve will be misaligned during connection, so that reinstallation is required, resulting in a problem of reduced installation efficiency of the threaded anchor rod. Therefore, the utility model provides an aluminum alloy formwork anchoring device to meet the demand. Utility Model Content

[0029] Specifically, by pre-embedded tube 3 at the installation point, the positioning hole of aluminum alloy formwork body 1 is aligned with the through hole 5 of embedded tube 3, and then the anchor rod 4 is inserted into the through hole 5 and the positioning hole of aluminum alloy formwork body 1, and the clamping block 12 is driven to rotate relative to each other by driving assembly 9, so that the clamping block 12 is clamped in the cavity 10, and then the handle 2 is rotated to move toward the direction of aluminum alloy formwork body 1, and the aluminum alloy formwork body 1 can be clamped by the cooperation of handle 2 and clamping block 12, so as to realize the installation of aluminum alloy formwork body 1, and the overall structure has simple installation steps, which avoids the phenomenon of dislocation when anchor rod 4 is inserted into embedded tube 3, improves the efficiency of anchor rod 4 installation, and solves the problem that when the existing aluminum alloy formwork anchoring device connects threaded anchor rod 4 and threaded sleeve 94 tube through threaded connector, the threaded connector and threaded sleeve 94 tube are inevitably dislocated when connected, so that reinstallation is required, resulting in reduced installation efficiency of threaded anchor rod 4.

[0030] It should be noted that when the holding block 12 enters the cavity 10 along the through hole 5, the driving assembly 9 can rotate the holding block 12 to a specified position so that the holding block 12 will not conflict when entering the through hole 5. At the same time, the installation and fixation of the embedded tube 3 are existing technologies.

[0031] like Figure 4 As shown, in this embodiment, the diameter of the cavity 10 is greater than the diameter of the through hole 5 , and the clamping block 12 can be clamped at the connection between the cavity 10 and the through hole 5 .

[0032] like Figure 4 and Figure 5As shown, in this embodiment, a receiving groove 8 for the movement of the holding block 12 is penetrated at the bottom of the anchor rod 4, and the driving assembly 9 includes a gear 93, which is fixedly connected to the holding block 12 and is located in the receiving groove 8, a threaded rod 91, which is movably arranged in the anchor rod 4, and the two ends of the threaded rod 91 extend to the outside of the threaded rod 91 respectively, and the bottom of the threaded rod 91 is fixedly connected with a rack 92 meshing with the gear 93, and the top of the threaded rod 91 is sleeved and threadedly connected with a threaded sleeve 94, and a movable plate 14 is sleeved on the threaded rod 91, and a movable groove 15 for the movement of the movable plate 14 is provided in the anchor rod 4, and the top of the movable plate 14 is fixedly connected with a spring 13, and the spring 13 is sleeved on the threaded rod 91. Specifically, by pulling the threaded rod 91, the threaded rod 91 drives the movable plate 14 to move upward, and the movable plate 14 squeezes the spring 13. At the same time, the threaded rod 91 drives the rack 92 to move upward, and the rack 92 drives the rack The wheel 93 rotates counterclockwise, and the gear 93 drives the holding block 12 to rotate, so that the holding block 12 is in a vertical state with the threaded rod 91, and then the threaded rod 91 is positioned by the threaded sleeve 94, and then the anchor rod 4 and the threaded rod 91 are pulled upward, so that the holding block 12 is clamped at the connection between the cavity 10 and the through port, and then the handle 2 is turned so that the handle 2 presses against the aluminum alloy template body 1, thereby completing the fixation of the aluminum alloy template body 1; when it is necessary to remove the anchor rod 4, by rotating the handle 2 and the threaded sleeve 94, it is moved away from the aluminum alloy template body 1, at this time, under the action of the spring 13, the movable plate 14 moves downward, so that the rack 92 drives the gear 93 to rotate clockwise, and the gear 93 drives the holding block 12 to rotate into the storage groove 8, so as to facilitate the removal of the anchor rod 4, and the overall operation is simple, which is convenient for the quick disassembly and assembly of the anchor rod 4 and the efficient fixation of the aluminum alloy template body 1.

[0034] Working principle:

[0035] By pre-embedding the embedded tube 3 at the installation point, aligning the positioning hole of the aluminum alloy formwork body 1 with the through hole 5 of the embedded tube 3, and then inserting the anchor rod 4 into the through hole 5 and the positioning hole of the aluminum alloy formwork body 1, by pulling the threaded rod 91, the threaded rod 91 drives the movable plate 14 to move upward, and the movable plate 14 squeezes the spring 13. At the same time, the threaded rod 91 drives the rack 92 to move upward, the rack 92 drives the gear 93 to rotate counterclockwise, and the gear 93 drives the holding block 12 to rotate, so that the holding block 12 and the threaded rod 91 are in a vertical state, and then the threaded rod 91 is positioned by the threaded sleeve 94, and then the anchor rod 4 and the threaded rod 91 are pulled upward. The grooved rod 91 allows the holding block 12 to be held at the connection between the cavity 10 and the through port, and then the handle 2 is rotated to press the handle 2 against the aluminum alloy formwork body 1, thereby completing the fixation of the aluminum alloy formwork body 1.
