Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically a wall tie for external scaffolding. Background Technology

[0002] Wall ties are components used in construction engineering to connect scaffolding to the main building structure. They are capable of transmitting tensile and compressive forces and are an important part of scaffolding. Wall ties play a crucial role in enhancing the overall stability of scaffolding, improving its load-bearing capacity, and preventing major accidents such as toppling or collapse.

[0003] Existing wall ties require scaffolding steel pipes to be pre-embedded in the wall, and then connected to the steel pipes on the scaffolding via connecting locks. The steel pipes are cylindrical with smooth surfaces, and the tensile force they can withstand when pre-embedded in the wall is relatively small. Furthermore, the pre-embedded steel pipes protruding from the wall need to be cut during dismantling, which affects the dismantling efficiency of the scaffolding, increases the wear and tear on the scaffolding steel pipes, and increases construction costs. To solve the above problems, this application proposes a new type of wall tie for external scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a wall tie for external scaffolding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wall tie for external scaffolding includes a pre-embedded metal fastener, which has a T-shaped structure. A connecting plate is fixedly welded to the horizontal end of the pre-embedded metal fastener, and a connecting threaded cylinder is fixedly welded to the horizontal end of the pre-embedded metal fastener via the connecting plate. A connecting rod is movably provided on one side of the connecting threaded cylinder, and a connecting fastener is movably provided on the surface of the connecting rod.

[0007] One end of the connecting rod is fixedly provided with a connecting thread, and one end of the connecting rod is threadedly connected to the connecting thread spool through the connecting thread.

[0008] In a preferred embodiment of this utility model, the surfaces of the wall-connecting embedded metal fastener and the connecting screw are both covered with plastic protective sleeves, and the plastic protective sleeves extend from both ends of the vertical side of the wall-connecting embedded metal fastener.

[0009] In a preferred embodiment of this utility model, the vertical ends of the wall-connecting embedded metal fastener are each welded with a horizontal fixing rod, and the horizontal fixing rods are arranged symmetrically.

[0010] In a preferred embodiment of the present invention, a locking nut is threaded onto the surface of the connecting thread head, and the locking nut abuts against the end surface of the connecting thread cylinder.

[0011] In a preferred embodiment of this utility model, a guide hole is provided through one side surface of the connecting fastener, and the connecting fastener is connected to the connecting rod through the guide hole.

[0012] In a preferred embodiment of this utility model, a limiting cap is fixedly provided on the surface of the connecting rod away from the connecting thread, and the limiting cap has a conical structure.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] The pre-embedded parts are embedded in the wall. The connecting rod can be connected to the connecting threaded cylinder through the connecting thread head, and the locking nut is used to abut against the surface of the connecting threaded cylinder, which can realize the quick installation of the connecting rod. The connecting fastener is slidably connected to the connecting rod through the guide hole. The end of the connecting rod is limited by the limit cap.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please refer to Figure 1-4 A wall tie for external scaffolding includes a wall tie embedded metal fastener 1, which has a T-shaped structure. A connecting plate 4 is fixedly welded to the horizontal end of the wall tie embedded metal fastener 1. A connecting threaded cylinder 5 is fixedly welded to the horizontal end of the wall tie embedded metal fastener 1 through the connecting plate 4. A connecting rod 6 is movably provided on one side of the connecting threaded cylinder 5. A connecting fastener 9 is movably provided on the surface of the connecting rod 6.

[0024] One end of the connecting rod 6 is fixedly provided with a connecting thread 7, and one end of the connecting rod 6 is threadedly connected to the connecting thread spool 5 through the connecting thread 7;

[0025] The pre-embedded metal fastener 1 is tied to the steel reinforcement structure on the side of the outer beam of the concrete floor or inside the shear wall using tie wire.

[0026] The wall-connecting embedded metal fastener 1 and the connecting screw spool 5 form an integral structure, which can improve the structural strength of the embedded part;

[0027] The connecting rod 6 can be threaded to the connecting spool 5 through the connecting thread 7, and the scaffolding steel pipe can be fixed through the connecting fastener 9, effectively transmitting tension and pressure. This ensures that the scaffolding frame is firmly and reliably connected to the main building structure, and facilitates exterior wall construction. Masonry construction and exterior wall plastering and cladding can be completed in one step. When dismantling the scaffolding, there is no need to add masonry or plastering, and it will not cause water seepage in the exterior wall. When dismantling the scaffolding, there is no need to cut the embedded steel pipe, resulting in higher construction efficiency.

[0028] Meanwhile, the wall-mounted metal fasteners 1, connecting screw spools 5, and plastic protective sleeves 3 are low-cost components. Except for the embedded parts, the other components can be reused, which can reduce construction costs.

[0029] The surfaces of the pre-embedded metal fastener 1 and the connecting screw spool 5 are both covered with plastic protective sleeves 3. The plastic protective sleeves 3 extend from both ends of the vertical side of the pre-embedded metal fastener 1. The plastic protective sleeves 3 can protect the pre-embedded metal fastener 1 and the connecting screw spool 5 and prevent them from rusting.

[0030] The vertical ends of the pre-embedded metal fastener 1 are each welded with a horizontal fixing rod 2. The horizontal fixing rod 2 is symmetrically arranged. The horizontal fixing rod 2 can increase the area of ​​the pre-embedded metal fastener 1 and the reinforcing bar binding, so as to improve the stability of the pre-embedded metal fastener 1.

[0031] The connecting thread 7 is threaded with a locking nut 8, which abuts against the end surface of the connecting thread spool 5. The locking nut 8 can lock the connecting rod 6, thereby improving the stability of the connecting fastener 9.

[0032] A guide hole is provided on one side surface of the connecting fastener 9. The connecting fastener 9 is connected to the connecting rod 6 through the guide hole. The connecting fastener 9 is slidably connected to the connecting rod 6 through the guide hole 10, which facilitates the quick assembly and separation of the connecting fastener 9 and the connecting rod 6.

[0033] A limiting cap 11 is fixedly provided on the surface of the end of the connecting rod 6 away from the connecting thread 7. The limiting cap 11 has a conical structure and can limit the connecting fastener 9 to prevent the connecting fastener 9 from separating from the connecting rod 6.

[0034] The inner wall of the connecting rod 6 is provided with a rubber ring 12. The rubber ring 12 has a semi-circular structure and two sets are spliced ​​together to form a circle. After the connecting fastener 9 is fixed to the scaffold steel pipe, the two sets of rubber rings 12 are spliced ​​together to form a circular structure. The rubber ring 12 is attached to the outer wall surface of the steel pipe, which can increase the friction with the surface of the steel pipe, thereby improving the stability of the steel pipe fixing.

[0035] The working principle of this utility model is as follows: During construction, the pre-embedded metal fastener 1 is tied to the steel reinforcement structure on the side of the outer beam of the concrete floor or inside the shear wall using tie wire. The pre-embedded metal fastener 1 is a T-shaped coupling, and the horizontal end of the pre-embedded metal fastener 1 is welded to the connecting thread cylinder 5 through the connecting plate 4, which can form an integral structure between the pre-embedded metal fastener 1 and the connecting thread cylinder 5, thereby improving the structural strength of the pre-embedded part. At the same time, horizontal fixing rods 2 are symmetrically welded to both ends of the vertical side of the pre-embedded metal fastener 1, which can increase the contact area between the pre-embedded metal fastener 1 and the steel reinforcement structure, and improve the stability of the binding of the pre-embedded metal fastener 1. After the outer beam of the concrete floor or the shear wall is poured, a mark is made at the connecting thread cylinder 5. After the outer beam of the concrete floor or the shear wall has solidified, the connecting tie rod 6 can be connected through the connecting thread. The head 7 is threadedly connected to the connecting screw spool 5 and abuts against the surface of the connecting screw spool 5 through the locking nut 8, which enables quick installation of the connecting rod 6. The connecting fastener 9 is slidably connected to the connecting rod 6 through the guide hole 10. The end of the connecting rod 6 is limited by the limit cap 11. The connecting fastener 9 can fix the scaffold steel pipe, effectively transmitting tension and pressure. This ensures that the scaffold frame is firmly and reliably connected to the main building structure, and facilitates the construction of the exterior wall. Masonry construction and exterior wall plastering and cladding can be completed in one step. When dismantling the scaffold, there is no need to add masonry or plastering, and it will not cause water seepage in the exterior wall. When dismantling the scaffold, there is no need to cut the embedded steel pipe, which increases the construction efficiency. At the same time, the cost of the wall-connecting embedded metal fastener 1, connecting screw spool 5 and plastic protective sleeve 3 is low. Except for the embedded parts, the other components can be reused, which can reduce construction costs.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
