Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a detachable wall tie. Background Technology

[0002] Scaffolding is indispensable in the construction process to facilitate construction. How to secure scaffolding while improving construction quality is a major issue in ensuring worker safety and property security, as well as increasing the building's acceptance rate. Currently, scaffolding is secured using traditional wall ties. These ties are typically pre-embedded before the concrete beams are poured. After the concrete beams are poured, the scaffolding is connected to the pre-embedded ties by welding or fasteners. This method is widely used because the components are simple to manufacture and operate. However, traditional wall ties are pre-embedded in the concrete structure, resulting in cumbersome installation steps, non-reusable ties, and material waste.

[0003] Patent CN211647260U discloses a detachable and fastening wall tie for fixing scaffolding wall-connecting steel pipes to structural components. It includes clamps, fasteners, and screws. One end of the fastener is fitted onto the outside of the wall-connecting steel pipe and locked by the screws. The other end of the fastener is connected to the clamp, which can clamp and release the structural component. This wall tie does not damage the structural component during installation, meaning it can be reused, thus saving construction costs. However, its installation requires adjusting the clamp by turning multiple screws, making the operation cumbersome and preventing rapid installation. Utility Model Content

[0004] This utility model proposes a detachable wall tie, which solves the problem that existing wall ties cannot be installed quickly.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A detachable wall tie includes a first support rod and a second support rod arranged in parallel. Clamps are rotatably connected to both ends of the second support rod. The tail end of each clamp engages with a support hole on the first support rod. The distance between the two support holes is less than the distance between the rotation centers of the two clamps. A locking mechanism is provided between the first and second support rods. Increasing the distance between the first and second support rods reduces the distance between the clamp heads. The clamps clamp the structural component through lever-like movement, thus connecting the wall tie to the structural component. The relative positions of the first and second support rods are easily adjustable, facilitating rapid installation of the wall tie. Furthermore, after the distance between the first and second support rods is adjusted, the locking mechanism secures the connection, maintaining a stable relative position and ensuring the stability of the connection between the wall tie and the structural component.

[0007] The locking mechanism includes a locking rod and a positioning tooth. The positioning tooth is disposed on the second support rod. The tail end of the locking rod is movably connected to the first support rod, and the head end of the locking rod engages with the positioning tooth. The locking rod is inclined relative to the first support rod, and the positioning tooth fixes the inclination angle of the locking rod, limiting the reduction of the distance between the first and second support rods, thereby ensuring the stability of the clamping of the structural component.

[0008] The locking rod is connected to the first support rod at its middle section via a spring. The spring applies a rotational force to the locking rod, causing it to move in a direction perpendicular to the first support rod. This ensures the stability of the locking rod's support for the first and second support rods, preventing the clamp from opening due to the first and second support rods approaching each other during use, thus avoiding connection failure between the wall tie and the structural component.

[0009] The number of positioning teeth is multiple, and the positioning teeth are arranged side by side on the second support rod. The multiple positioning teeth correspond to different tilt angles of the locking rod, thereby enabling the locking mechanism to lock the first support rod and the second support rod at different intervals, realizing the adjustment of the clamp opening distance, and making the wall tie suitable for structural components of different thicknesses.

[0010] The clamp includes clamping rods, the heads of which are bent towards the middle of the two clamping rods. The bent clamping rods are suitable for structural members with steps, ensuring that the heads of the clamping rods are in contact with the large surface of the structural member, thus ensuring the stability of the wall tie installation.

[0011] The clamping rod has a clamping head movably connected to its head. The clamping head can rotate freely at the head of the clamping rod, and during the installation of the wall tie, the clamping head can form a surface-to-surface contact with the structural component, enhancing the installation stability of the wall tie.

[0012] The clamping surface of the clamping head is provided with an anti-slip pad. The anti-slip pad increases the friction between the clamping head and the structural component, preventing the wall tie from sliding on the structural component under force.

[0013] The clamping rod is equipped with a stop plate at its tail end. The stop plate limits the movement of the first support rod to prevent the first support rod from detaching from the tail end of the clamping rod due to excessive distance between the first and second support rods, thus ensuring the structural stability of the wall tie.

[0014] A connecting rod is connected to the first support rod. The connecting rod is arranged horizontally and is connected to the first support rod by welding. The first support rod is connected to the scaffolding through the connecting rod.

[0015] The second support rod is equipped with a support head. The support head positions the second support rod to ensure accurate installation of the wall tie.

[0016] The beneficial effects of this utility model are as follows: the adjustment of the distance between the first support rod and the second support rod can drive the clamp to swing, thereby realizing the adjustment of the distance between the clamp head. The clamp clamps the structural component through lever-type movement, realizing the connection between the wall tie and the structural component. The relative position adjustment of the first support rod and the second support rod is convenient, which facilitates the rapid installation of the wall tie. In addition, after the distance between the first support rod and the second support rod is adjusted, it is fixed by the locking mechanism, and the relative position of the first support rod and the second support rod remains stable, thereby ensuring the connection stability between the wall tie and the structural component.

[0017] The locking mechanism supports the first support rod and the second support rod. When the wall tie is in use, the locking mechanism can prevent the first support rod and the second support rod from getting close to each other and causing the clamp to open, thereby avoiding the failure of the connection between the wall tie and the structural component.

[0018] Multiple positioning teeth correspond to different tilt angles of the locking rod, thereby enabling the locking mechanism to lock the first support rod and the second support rod at different intervals, realizing the adjustment of the clamp opening distance, and making the wall tie suitable for structural components of different thicknesses.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, such as Figure 1 As shown, a detachable wall tie includes a first support rod 2 and a second support rod 3 arranged in parallel. Clamps are rotatably connected to both ends of the second support rod 3. The tail end of the clamp engages with a support hole 21 on the first support rod 2. The distance between the two support holes 21 is less than the distance between the rotation centers of the two clamps. A locking mechanism 5 is provided between the first support rod 2 and the second support rod 3. Adjusting the distance between the first support rod 2 and the second support rod 3 adjusts the opening size of the clamps. Specifically, when the distance between the first support rod 2 and the second support rod 3 increases, the distance between the tail ends of the clamps increases, and the distance between the heads of the clamps decreases. At this time, the heads of the clamps can clamp the structural component 6. After the clamps clamp the structural component 6, the locking mechanism supports and fixes the distance between the first support rod 2 and the second support rod 3, keeping the relative positions of the first support rod 2 and the second support rod 3 stable, thereby ensuring the connection stability between the wall tie and the structural component 6.

[0025] Furthermore, such as Figure 2 As shown, the locking mechanism 5 includes a locking rod 51 and a positioning tooth 32. The positioning tooth 32 is disposed on the second support rod 3. The tail end of the locking rod 51 is movably connected to the first support rod 2, and the head end of the locking rod 51 is engaged with the positioning tooth 32. The middle part of the locking rod 51 is connected to the first support rod 2 via a spring 52. In this embodiment, there are two locking mechanisms 5, and the two locking mechanisms 5 are arranged opposite to each other to ensure the stability of the locking mechanism 5 in supporting the first support rod 2 and the second support rod 3, and to avoid the first support rod 2 and the second support rod 3 tilting relative to each other. The locking rod 51 is arranged at an angle relative to the first support rod 2, and the positioning tooth 32 fixes the angle of inclination of the locking rod 51, limiting the reduction of the distance between the first support rod 2 and the second support rod 3, thereby ensuring the stability of the clamp on the structural member 6.

[0026] Furthermore, there are multiple positioning teeth 32, which are arranged side by side on the second support rod 3. The multiple positioning teeth 32 correspond to different tilt angles of the locking rod 51, thereby enabling the locking mechanism 5 to lock the first support rod 2 and the second support rod 3 at different intervals, realizing the adjustment of the clamp opening distance, and making the wall tie suitable for structural members 6 of different thicknesses.

[0027] The installation method of the wall tie on the structural component 6 is as follows: The operator manually opens the locking rod 51, cancels the distance limit of the locking rod 51 on the first support rod 2 and the second support rod 3, and pushes the first support rod 2 and the second support rod 3 closer to each other. At this time, the clamp head opens. Move the wall tie to the installation position on the structural component 6, pull the first support rod 2 away from the second support rod 3, and the distance between the clamp heads decreases. The clamp clamps the structural component 6. At the same time, the locking rod 51 swings in the direction perpendicular to the first support rod 2 under the action of the spring 52. The locking rod 51 provides support for the distance between the first support rod 2 and the second support rod 3, ensuring the stability of the distance between the first support rod 2 and the second support rod 3, and realizing the connection between the wall tie and the structural component 6.

[0028] Example 2, based on Example 1, provides a detachable wall tie. The clamp includes clamping rods 4, the heads of which are bent towards the middle of the two clamping rods 4. The bent clamping rods 4 can be used with stepped structural members 6, ensuring that the heads of the clamping rods 4 are in contact with the large plane of the structural member 6, ensuring the stability of the wall tie installation, and improving the applicability of the wall tie.

[0029] Furthermore, a clamping head 41 is movably connected to the head of the clamping rod 4. The clamping head 41 can rotate freely at the head of the clamping rod 4, allowing it to form surface-to-surface contact with the structural member 6 during wall connection installation, thus enhancing the installation stability of the wall connection. An anti-slip pad is provided on the clamping surface of the clamping head 41. In this embodiment, the anti-slip pad is a rubber pad, which increases the friction between the clamping head 41 and the structural member 6, preventing the wall connection from sliding on the structural member 6 under force.

[0030] Furthermore, a stop plate is provided at the tail end of the clamping rod 4. The stop plate limits the first support rod 2 to prevent the first support rod 2 from detaching from the tail end of the clamping rod 4 due to excessive distance between the first support rod 2 and the second support rod 3, thus ensuring the structural stability of the wall tie.

[0031] Furthermore, a connecting rod 1 is connected to the first support rod 2. The connecting rod 1 is arranged horizontally and is welded to the first support rod 2. The first support rod 2 is connected to the scaffold 7 through the connecting rod 1. A support head 31 is provided on the second support rod 3. The support head 31 positions the second support rod 3 to ensure accurate installation of the wall tie.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
