Technical Field

[0001] This utility model relates to the technical field of external scaffolding wall ties, specifically a pre-embedded reusable external scaffolding wall tie. Background Technology

[0002] Wall ties generally refer to components that enhance the stability of other structures by connecting to reliable fixed ends. In construction engineering, they are used to connect scaffolding frames to the main building structure and can transmit tension and pressure.

[0003] Most of the commonly available pre-embedded scaffolding wall ties on the market are similar in structure, generally consisting of two parts: pre-embedded parts and bolts. The pre-embedded parts are metal pipes or metal pipes with plastic coating, which are directly embedded in the wall. Bolts are driven into the pre-embedded parts, and the external scaffolding is connected to the bolts. In actual use, there are some functional deficiencies and room for improvement. For example, after the scaffolding is dismantled at the end of the project, the pre-embedded parts remain in the wall and cannot be reused. The cost is still relatively high, and the pre-embedded parts do not have the function of being reusable.

[0004] Now, a new type of pre-embedded, reusable external scaffolding wall tie is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded, reusable external scaffolding wall tie to solve the problem mentioned in the background art of not having the function of reusable pre-embedded parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded reusable external scaffolding wall tie, comprising a PVC pipe, a steel pipe inserted into the right side of the PVC pipe, a hexagonal head welded to the right side of the steel pipe, a bolt rod inserted into the right side of the steel pipe, and an external anchor plate fixedly connected to the right side of the PVC pipe.

[0007] As a further technical solution of this utility model, the PVC pipe has internal threads and the steel pipe has external threads, and the external threads of the steel pipe and the internal threads of the PVC pipe match each other.

[0008] As a further technical solution of this utility model, the inside of the steel pipe is threaded, and the outside of the bolt rod is threaded, and the threads on the outside of the bolt rod and the threads inside the steel pipe are matched.

[0009] As a further technical solution of this utility model, the inner diameter of the hexagonal head is consistent with the inner diameter of the steel pipe, and the horizontal center lines of the steel pipe and the hexagonal head coincide.

[0010] As a further technical solution of this utility model, a piston block is horizontally placed on the left side inside the PVC pipe, an injection cavity is fixedly connected to the left side of the PVC pipe, an inner anchor plate is fixedly connected to the left side of the injection cavity, a mortar injection pipe is movably connected to the right side of the injection cavity, and a mortar injection port is provided on the right side of the mortar injection pipe.

[0011] As a further technical solution of this utility model, the mortar injection port, the mortar injection pipe, and the injection cavity are internally connected, the outer diameter of the piston block is adapted to the inner diameter of the PVC pipe, and the piston block can slide left and right along the inside of the PVC pipe.

[0012] As a further technical solution of this utility model, a positioning ring is fixedly connected to the right side of the outer anchor plate, and the upper and lower ends of the positioning ring are respectively provided with limit pin insertion holes.

[0013] As a further technical solution of this utility model, the inner diameter of the positioning ring is the same as the inner diameter of the PVC pipe, and the limiting pin holes are symmetrically distributed about the horizontal center line of the positioning ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the pre-embedded reusable external frame wall tie not only realizes the function of the pre-embedded part being reusable, but also realizes the function of easy filling of the interior, and also realizes the function of easy sealing of the pipe opening;

[0015] (1) By setting up PVC pipe, steel pipe, hexagonal head, bolt rod, outer anchor plate and inner anchor plate, when in use, the PVC pipe, outer anchor plate and inner anchor plate are partially embedded in the wall. The steel pipe serves as the inner lining of the PVC pipe, which increases the strength on the one hand and is used to connect with the bolt rod on the other. The scaffolding is directly fixed on the bolt rod. As the scaffolding is dismantled, the bolt rod is pulled out. At this time, the steel pipe can be unscrewed for recycling by using a wrench on the hexagonal head, which is convenient for secondary use and has a lower cost. It realizes the function of reusable embedded parts.

[0016] (2) By setting up a mortar injection port, a mortar injection pipe, a piston block and an injection cavity, when in use, as the steel pipe is pulled out, the mortar pump pipe is connected to the mortar injection port, and concrete mortar is continuously injected into the injection cavity through the mortar injection pipe. The mortar enters the PVC pipe along the injection cavity. As the mortar pressure increases, it can push the piston block to move outward. After the mortar dries and solidifies, it can fill and support the inside of the PVC pipe, avoid the hollow in the wall, and realize the function of easy filling of the inside.

[0017] (3) By setting a positioning ring and a limiting pin insertion hole, when filling mortar, a thin iron wire or bolt is used as a pin and inserted along the limiting pin insertion hole on the positioning ring. The pin can block the piston block and prevent the mortar from flowing out, keeping its interior dense and realizing the function of easy sealing of the pipe opening. Attached Figure Description

[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: Please refer to Figure 1-4 An embedded reusable external scaffolding wall tie includes a PVC pipe 1, a steel pipe 2 inserted into the right side of the PVC pipe 1, a hexagonal head 3 welded to the right side of the steel pipe 2, a bolt rod 4 inserted into the right side of the steel pipe 2, and an external anchor plate 5 fixedly connected to the right side of the PVC pipe 1.

[0025] The PVC pipe 1 has internal threads, the steel pipe 2 has external threads, the external threads of the steel pipe 2 match the internal threads of the PVC pipe 1, the steel pipe 2 has internal threads, the bolt rod 4 has external threads, the external threads of the bolt rod 4 match the internal threads of the steel pipe 2, the inner diameter of the hexagonal head 3 matches the inner diameter of the steel pipe 2, and the horizontal center lines of the steel pipe 2 and the hexagonal head 3 coincide, which facilitates reuse and turnover.

[0026] Specifically, such as Figure 1 and Figure 2As shown, steel pipe 2 serves as the inner lining of PVC pipe 1, increasing strength and connecting with bolt rod 4. The scaffolding is directly fixed to bolt rod 4. As the scaffolding is dismantled, bolt rod 4 is pulled out. At this point, by using a wrench to fasten the hexagonal head 3, steel pipe 2 can be unscrewed for recycling, facilitating secondary use and reducing operating costs.

[0027] A piston block 8 is horizontally placed on the left side inside the PVC pipe 1. An injection chamber 9 is fixedly connected to the left side of the PVC pipe 1. An inner anchor plate 10 is fixedly connected to the left side of the injection chamber 9. A mortar injection pipe 7 is movably connected to the right side of the injection chamber 9. A mortar injection port 6 is provided on the right side of the mortar injection pipe 7. The mortar injection port 6, the mortar injection pipe 7, and the injection chamber 9 are connected internally. The outer diameter of the piston block 8 is matched with the inner diameter of the PVC pipe 1. The piston block 8 can slide left and right along the inside of the PVC pipe 1. The strength reduction caused by the hollow wall can be avoided by filling with mortar.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, concrete mortar is continuously injected into the injection chamber 9 through the mortar injection pipe 7. The mortar enters the PVC pipe 1 along the injection chamber 9. As the mortar pressure increases, it pushes the piston block 8 to move outward. After the mortar dries and solidifies, it can fill and support the inside of the PVC pipe 1, thus preventing hollowness in the wall.

[0029] A positioning ring 11 is fixedly connected to the right side of the outer anchor plate 5. The upper and lower ends of the positioning ring 11 are respectively provided with limit pin insertion holes 12. The inner diameter of the positioning ring 11 is the same as the inner diameter of the PVC pipe 1. The limit pin insertion holes 12 are symmetrically distributed about the horizontal center line of the positioning ring 11, which can close the pipe opening and prevent the piston from being pushed out.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, the pin is inserted along the limiting pin insertion hole 12 on the positioning ring 11. The pin can block the piston block 8, prevent the mortar from flowing out, and keep its interior in a dense state.

[0031] Working Principle: In use, the PVC pipe 1, outer anchor plate 5, and inner anchor plate 10 are partially embedded in the wall. The steel pipe 2 serves as the inner lining of the PVC pipe 1, increasing its strength and connecting it to the bolt rod 4. The scaffolding is directly fixed to the bolt rod 4. As the scaffolding is dismantled, the bolt rod 4 is pulled out. At this point, by using a wrench on the hexagonal head 3, the steel pipe 2 can be unscrewed for recycling and reuse, resulting in lower operating costs. After the steel pipe 2 is pulled out, the mortar pump pipe is connected to the mortar injection port 6. Concrete mortar is continuously injected into the injection chamber 9 through the mortar injection pipe 7. The mortar enters the interior of the PVC pipe 1 along the injection chamber 9. As the mortar pressure increases, it pushes the piston block 8 outward. Once the mortar dries and solidifies, it fills and supports the interior of the PVC pipe 1, preventing hollow areas from appearing in the wall. When filling the mortar, a thin iron wire or bolt is used as a pin and inserted along the limiting pin insertion hole 12 on the positioning ring 11. The pin can block the piston block 8, prevent the mortar from flowing out, and keep its interior in a dense state.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
