Description

Technical Field

[0001] This utility model relates to an aluminum alloy template anchoring structure, belonging to the field of template fixing technology. Background Technology

[0002] When pouring concrete walls, formwork is required. After the aluminum alloy side formwork is placed at the pouring location, it needs to be secured and locked together using anchoring devices. Currently, tie bolts are commonly used, with both ends of the tie bolts passing through the aluminum alloy side formwork and then locked in place using anchor nuts. However, during the drying process of the concrete pour, the tie bolts and nuts on the outside of the side formwork are corroded by concrete slurry or rainwater, causing the threads to become clogged or rusted. This makes disassembling the aluminum alloy formwork time-consuming and laborious, and the tie bolts on the outside of the side formwork protrude, easily colliding with the legs of construction workers passing by, causing injury. Furthermore, the rust on the tie bolts increases the risk of tetanus infection for construction workers, posing a significant safety hazard. Utility Model Content

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example 1, such as Figures 1 to 4 As shown, this utility model is an aluminum alloy template anchoring structure, including tie bolts 1 connecting the two aluminum alloy side templates 4. Both ends of the tie bolts 1 are provided with locking nuts 3 and washers 8. Both ends of the tie bolts 1 are fitted with protective sleeves 2. The inner hole of the protective sleeve 2 is hexagonal and fits the outer wall of the locking nut 3. The outer end of the protective sleeve 2 is closed. The outer end face of the protective sleeve 2 is a smooth spherical surface 6 that protrudes outward. The inner end of the protective sleeve 2 is provided with a protective boss 5 that fits the washer 8 inside. The aluminum alloy side template 4 is provided with an annular protective groove 11 that cooperates with the protective boss 5.

[0019] During the work, aluminum alloy side formwork 4 is placed at the position to be poured. Multiple tie bolts 1 are installed on the lower part of the aluminum alloy side formwork 4 on both sides along the front and back direction. Both ends of each tie bolt 1 are fixed by lock nuts 3 and washers 8. Then, protective sleeves 2 are put on both ends of the tie bolts 1. The inner protective protrusions 5 of the protective sleeves 2 are put on the washers 8 and are inserted into the protective slots 11 to prevent concrete slurry or rainwater from entering the protective sleeves 2 and corroding the tie bolts 1 and lock nuts 3.

[0020] In Example 2, based on Example 1, a circular limiting protrusion 9 is provided at the center of the outer end face of the inner hole of the protective sleeve 2, and a limiting groove is provided at the outer end of the tie bolt 1 to cooperate with the limiting protrusion 9. The limiting protrusion 9 and the limiting groove are interference fit. When installing the protective sleeve 2, the limiting protrusion 9 is engaged in the limiting groove to support and fix the outer end of the protective sleeve 2.

[0021] The protective sleeve 2 on the outer side of the limiting bracket protrusion 9 is provided with a rotating through hole 7. When it is necessary to remove the locking nut 3, a steel bar or steel pipe can be inserted into the rotating through hole 7, and then the steel bar or steel pipe can be rotated to drive the protective sleeve 2 and the locking nut 3 to rotate, thereby removing the locking nut 3.

[0023] The tie bolt 1 provides good anchoring for the lower part of the aluminum alloy side formwork 4, but not for the top, which can easily cause deformation of the top of the aluminum alloy side formwork 4. Therefore, vertical limiting square tubes 14 are provided on the outer top of both sides of the aluminum alloy side formwork 4. Connecting square tubes 12 are fixedly connected to the inner top of the limiting square tubes 14 on both sides. U-shaped limiting channel steel 13 is fixed to the aluminum alloy side formwork 4 on the inner side of the limiting square tubes 14. The slot of the limiting channel steel 13 faces outward.

[0024] After the tie bolts 1 at the bottom of the aluminum alloy side template 4 are installed and fixed, the limiting square tubes 14 can be inserted from the top into the corresponding limiting channel steels 13 on both sides to anchor and tie the top.

[0025] The bottom of the limiting channel steel 13 is provided with a fixing hole, and a fixing bolt 16 is installed in the fixing hole. The aluminum alloy side template 4 is provided with a threaded hole that mates with the fixing bolt 16.
