[0002] Composite slab aluminum formwork is a construction technology that combines aluminum alloy formwork with precast composite slabs. It is mainly used for shear wall structures of high-rise buildings. When working with composite slab aluminum formwork, workers need to wear safety belts and attach them to the mold or the erected steel cables to ensure their personal safety.

[0003] Existing technologies lack a structure for connecting and attaching to the composite aluminum formwork, resulting in safety belts being mostly attached to the outer steel frame, limiting their working range to the length of the connecting strap. This restricts both the working range and flexibility. To address these shortcomings, this invention designs a safety belt attachment device for composite aluminum formwork construction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety belt fastening device for composite aluminum formwork construction, which has the advantage of being able to be connected and fastened to the composite aluminum formwork via a movable snap-fit.

[0005] This utility model provides the following technical solution: a safety belt fastening device for composite aluminum formwork construction, including a safety belt body, a connecting strap on the back of the safety belt body, a movable fastening mechanism at the bottom end of the connecting strap for easy connection with the composite aluminum formwork, and a locking mechanism on the movable fastening mechanism for easy adjustment and locking of the opening and closing width.

[0006] The movable hooking mechanism includes a connecting arm, a movable pulley, a side arm, an adjusting hole, an adjusting arm, an adjusting bolt, and a limiting pulley. The connecting arm is located at the bottom end of the lower connecting buckle. The movable pulley is rotatably connected to the connecting arm. The top end of the side arm is slidably sleeved on the connecting arm. The adjusting hole is opened through the side arm. The adjusting arm is located on the inner side of the side arm. The adjusting bolt is located on the adjusting arm. The limiting pulley is rotatably connected to the bottom end of the adjusting arm.

[0007] As a preferred technical solution of this utility model, the locking mechanism includes a movable cover, a check lock block, a push plate, a pull rod, a spring, and a check groove. The movable cover is fixedly connected to the top of the side arm, the check lock block is inserted through the top of the side arm, the push plate is fixedly connected to the upper surface of the check lock block, the pull rod is fixedly connected to the upper surface of the push plate, the spring is sleeved on the pull rod, and the check groove is formed on the upper surface of the connecting arm.

[0008] As a preferred embodiment of this utility model, the back of the seat belt body is provided with an upper connecting buckle, and the bottom end of the connecting strap is provided with a connecting strap.

[0009] As a preferred embodiment of this utility model, the adjusting bolt is inserted and fixedly disposed in the adjusting hole.

[0010] As a preferred embodiment of this utility model, the movable pulley and the limiting pulley are slidably connected to the upper and lower surfaces of the composite plate aluminum mold, respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of safety belt fastening device for composite aluminum formwork construction involves separating the side arm and adjusting arm by unscrewing the adjusting bolt. The combined length of the side arm and adjusting arm is adjusted according to the thickness of the aluminum formwork, and the adjusting bolt is inserted into the adjusting hole to re-secure them. Then, pulling the pull rods on one side one by one pulls the check lock blocks upwards, disengaging them from the check grooves to release the lock on the side arm. Pushing the side arm outwards to its outermost position, the pull rods are released, and the spring rebounds, pushing the push plate downwards to insert the check lock blocks back into their corresponding check grooves to lock the side arm. Once both side arms have moved to their outermost positions, the connecting arm and moving pulley are placed on the upper surface of the aluminum formwork. Simultaneously, position the side arms, adjusting arms, and limiting pulleys on both sides of the aluminum mold. Then, push the side arms inward simultaneously, bringing the left and right sets of side arms and adjusting arms close to the sides of the aluminum mold without clamping it. At the same time, move the limiting pulleys at the bottom of the adjusting arms to the bottom of the aluminum mold. At this point, the connecting arm, side arms, adjusting arms, and limiting pulleys slide and clamp onto the aluminum mold. Connect the safety belt body, upper connecting buckle, and connecting strap to the connecting arm using the lower connecting buckle to complete the fastening. The movable fastening mechanism can slide on the aluminum mold, improving the worker's working range and flexibility. This device facilitates improved flexibility for workers after wearing and fastening the safety belt body. Attached Figure Description

The connecting arm 301 is located at the bottom end of the lower connecting buckle 103. The movable pulley 302 is rotatably connected to the connecting arm 301. The top end of the side arm 303 is slidably sleeved on the connecting arm 301. The adjusting hole 304 is slidably opened on the side arm 303. The adjusting arm 305 is located on the inner side of the side arm 303. The adjusting bolt 306 is located on the adjusting arm 305. The limiting pulley 307 is rotatably connected to the bottom end of the adjusting arm 305. The adjusting bolt 306 is inserted and fixedly installed in the adjusting hole 304. The movable pulley 302 and the limiting pulley 307 are slidably connected to the upper and lower surfaces of the composite plate aluminum mold, respectively.

[0025] By setting up connecting arm 301, side arm 303, adjusting arm 305 and limiting pulley 307, the safety belt body 1 can be attached to the composite aluminum mold to prevent fall. By setting up moving pulley 302 and limiting pulley 307, the connecting arm 301, side arm 303 and adjusting arm 305 can slide on the composite aluminum mold, improving the worker's activity space and flexibility after being attached.

[0026] Please see Figure 3 - Figure 5 The locking mechanism 2 includes a movable cover 201, a check lock block 202, a push plate 203, a pull rod 204, a spring 205, and a check groove 206. The movable cover 201 is fixedly connected to the top of the side arm 303. The check lock block 202 is inserted through the top of the side arm 303.

By setting a pull rod 204, the check lock block 202 is pulled out of the check groove 206 to unlock.

[0028] Working principle: When a safety belt fastening device for composite aluminum formwork construction is used, in the initial state, the connecting belt 102 is first connected to the safety belt body 1 and the connecting arm 301 through the upper connecting buckle 101 and the lower connecting buckle 103 respectively. Two movable pulleys 302 are rotatably connected to the connecting arm 301, and a side arm 303 is also connected. The side arm 303 is connected to the adjusting arm 305 and the limiting pulley 307 through the adjusting hole 304 and the adjusting bolt 306, so that the connecting arm 301 can be hooked onto the composite aluminum formwork for sliding locking. The side arm 303 and the connecting arm 301 are locked by the anti-return locking block 202 and the anti-return groove 206, and the anti-return locking block 202 is limited by the push plate 203 and the spring 205, so that the movable fastening mechanism 3 can be hooked onto composite aluminum formwork of different specifications.

[0029] When it is necessary to improve the flexibility of the worker wearing the safety belt body 1 and after fastening, first unscrew the adjusting bolt 306 to separate the side arm 303 and the adjusting arm 305. Adjust the length of the side arm 303 and the adjusting arm 305 after combination according to the thickness of the aluminum mold, and use the adjusting bolt 306 to insert into the adjusting hole 304 to re-fix them. Then, pull the pull rod 204 on one side at a time to pull the anti-return locking block 202 upward and disengage it from the inside of the anti-return groove 206 to release the lock on the side arm 303. Move the side arm 303 outward to the outermost end, and then release the pull rod 204. The spring 205 rebounds and pushes the push plate 203 downward to insert the anti-return locking block 202 back into the corresponding anti-return groove 206 to lock the side arm 303. After both sides of the side arm 303 have moved to the outermost end, connect the connecting arm 301 and the moving pulley 3. 02 is placed on the upper surface of the aluminum mold, with the side arm 303, adjusting arm 305 and limiting pulley 307 located on both sides of the aluminum mold. Then, the side arm 303 is pushed inward at the same time, so that the two sets of side arms 303 and adjusting arm 305 are close to the sides of the aluminum mold but do not clamp it. At the same time, the limiting pulley 307 at the bottom of the adjusting arm 305 moves to the bottom of the aluminum mold. At this time, the connecting arm 301, side arm 303, adjusting arm 305 and limiting pulley 307 slide and clamp on the aluminum mold. After connecting the safety belt body 1, upper connecting buckle 101 and connecting strap 102 to the connecting arm 301 using the lower connecting buckle 103, the fastening is completed. At the same time, the movable fastening mechanism 3 can slide on the aluminum mold, improving the worker's working range and flexibility. This device facilitates the improvement of the worker's flexibility after wearing and fastening the safety belt body 1.
