Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a detachable scaffolding wall connecting piece. Background Art

[0002] Currently, building construction projects often require the erection of scaffolding outside buildings for on-site production and construction needs. To ensure the stability of the scaffolding and ensure safe on-site construction, wall ties must be calculated and installed according to the scaffolding plan. Currently, the most commonly used wall tie connection method involves pre-embedded vertical steel pipes in the main structure, which are then secured to the external scaffolding poles using horizontal steel pipes. Traditional wall ties use a large amount of material, are non-recyclable, hinder subsequent masonry and plastering work, and pose a high risk of leakage on the building's exterior walls.

[0003] Utility model patent publication number CN219365371U discloses a recyclable scaffolding wall connector assembly, comprising a horizontal tube, a sleeve, and through-wall bolts. While this solution eliminates the need for pre-embedded components within the main structure, the use of through-wall bolts creates a risk of wall leakage. Therefore, developing a removable scaffolding wall connector that is recyclable, provides reliable connections, and minimizes leakage risk is a pressing technical challenge. Utility Model Content

[0004] Due to the above-mentioned defects in the prior art, the utility model provides a detachable scaffolding wall connection part, which is connected by a small number of pre-embedded and sleeve-positioned bolts, and most of the components are recycled, which greatly reduces the material usage, and has a reliable connection and low leakage risk.

[0005] To achieve the above-mentioned object, the present invention provides a detachable scaffolding wall connecting member, comprising a transverse steel pipe connected to an outer scaffolding upright, characterized in that it also includes:

[0006] A sleeve bolt assembly embedded in a building wall comprises a sleeve and a bolt-nut assembly; the sleeve comprises an end and a tube body, the end being provided with a hexagonal nut fixing groove; the hexagonal nut being arranged in the hexagonal nut fixing groove;

[0007] An L-shaped flat iron, wherein bolt holes are provided on the vertical section and the horizontal section is fixedly connected to the horizontal steel pipe;

[0008] A bolt matched with the hexagonal nut passes through the bolt hole and then penetrates from the open end of the tube body and is fastened by the hexagonal nut.

[0009] The sleeve bolt assembly of the wall connecting piece is embedded in the wall through the formwork before the building wall is cast. After the building wall is cast, it can be used as a wall connecting piece by connecting it with the L-shaped flat iron. After the scaffolding is dismantled, the connecting bolts, flat iron and transverse steel pipe are recovered and reused.

[0010] Furthermore, the length of the end is 18.4 mm, and the length of the tube body is 65 mm.

[0011] Furthermore, the specifications of the hexagonal nuts and bolts are M14.

[0012] Furthermore, the sleeve is a 2mm thick PVC sleeve.

[0013] Furthermore, the thickness of the L-shaped flat iron is 5 mm.

[0014] Compared with the prior art, the above utility model has the following advantages or beneficial effects:

[0027] Example

[0028] See also Figures 1 to 5 This embodiment provides a detachable scaffolding wall connecting member, including a transverse steel pipe 1 connected to the outer scaffolding upright, a sleeve bolt assembly 2, and an L-shaped flat iron 3. The sleeve bolt assembly 2 is embedded in the building wall 4 and includes a sleeve 21 and a bolt and nut assembly; the sleeve 21 includes an end 211 and a tube body 212, and the end 211 is provided with a hexagonal nut fixing groove; the hexagonal nut 22 is arranged in the hexagonal nut fixing groove. A bolt hole 31 is provided on the vertical section of the L-shaped flat iron 3, and the transverse section is fixedly connected to the transverse steel pipe 1. The bolt 23 that matches the hexagonal nut 22 passes through the bolt hole 31, then penetrates from the open end of the tube body 212, and is fastened by the hexagonal nut 22.

[0029] The steps for using the wall connecting piece are as follows:

[0030] First, the wall connection piece is positioned and a hole is drilled in the building wall template at the corresponding position. The diameter of the hole is just enough to allow the bolt 23 to penetrate.

[0031] Next, the bolt 23 passes through the template opening and then enters from the open end of the tube body 212 , and is fastened by the hexagonal nut 22 , and the sleeve bolt assembly 2 is assembled on the template.

[0032] Next, pour concrete for the building wall 4. After the formwork is removed, remove the bolts 23, insert them through the bolt holes 31 in the L-shaped flat iron 3, and then through the open end of the tube 212, tightening them with hexagonal nuts 22. The transverse section of the L-shaped flat iron 3 is fixedly connected to the transverse steel tube 1, preferably by welding, but can also be connected by pipe clamps or other methods.

[0033] Finally, after the scaffolding is dismantled, the connecting bolts, flat irons and transverse steel pipes are recycled and reused.

[0034] The sleeve bolt assembly of the wall connecting piece is embedded in the wall through the formwork before the building wall is cast. After the building wall is cast, it can be used as a wall connecting piece by connecting it with the L-shaped flat iron. After the scaffolding is dismantled, the connecting bolts, flat iron and transverse steel pipe are recovered and reused.

[0035] As a preferred, feasible solution, the length of the end cap 211 is 18.4 mm, and the length of the tube body 212 is 65 mm. The hexagonal nut 22 and bolt 23 are M14 in size.

[0036] As an implementable preferred technical solution, the sleeve 21 is a 2 mm thick PVC sleeve, which is easily available on site.

[0037] As an implementable preferred technical solution, the thickness of the L-shaped flat iron 3 is 5mm, which can be adjusted according to the load of the L-shaped flat iron and the principle of saving materials. When the load is large, a rib plate can be added between the two sections of the flat iron.

[0038] It can be seen that the wall connecting parts are effectively connected to the main body of the building to ensure the safety and stability of the frame; the assembly is simple, the cost is low, the embedded depth is adjustable, the impact on subsequent masonry is small, and the hidden danger of leakage of the exterior wall is reduced; the construction difficulty is small and the operation is simple; most components can be used in rotation to improve the utilization rate of materials.

[0039] In summary, the utility model provides a detachable scaffolding wall connection component, including a transverse steel pipe connected to the outer scaffolding upright, a sleeve bolt assembly embedded in the building wall, and an L-shaped flat iron. The sleeve bolt assembly includes a sleeve and a bolt and nut assembly; the sleeve includes an end and a tube body, and a hexagonal nut fixing groove is provided in the end head; the hexagonal nut is provided in the hexagonal nut fixing groove. Bolt holes are provided on the vertical section of the L-shaped flat iron, and the transverse section is fixedly connected to the transverse steel pipe. The bolt matching the hexagonal nut passes through the bolt hole, and then passes through the open end of the tube body and is tightened by the hexagonal nut. By connecting with a small amount of pre-embedded and sleeve-positioned bolts, most of the components are recycled, which greatly reduces the material consumption, and the connection is reliable and the risk of leakage is small.
