Description

Technical Field

[0001] This utility model belongs to the field of building construction, specifically relating to a reusable, large-span, high-rise, high-wall-connecting device. Background Technology

[0002] Wall ties are a common building construction component. External scaffolding is connected and fixed to the building through wall ties, which improves the load-bearing capacity of the external scaffolding against lateral forces.

[0003] Construction specifications stipulate that the vertical spacing of wall ties for scaffolding should not exceed 4m, and the horizontal spacing should not exceed 3 times the spacing of scaffolding uprights. When the floor height of a frame structure (i.e., building structure) is greater than 4m, and the column spacing of the frame columns is greater than 3 times the spacing of scaffolding uprights, it is more difficult to install wall ties for scaffolding.

[0004] For large-span, high-rise frame structures, traditional wall tie connection methods include: steel pipe column clamps + tied formwork support frames, angle steel lattice columns, and steel pipe column clamps + steel pipe columns. However, these wall tie methods hinder exterior wall construction. Currently, most building exterior walls use precast panels. Using common wall tie methods requires drilling holes during panel installation, and improper sealing of these holes can easily lead to structural water seepage. Furthermore, common wall tie embedded devices are not reusable, increasing construction costs and wasting resources. Utility Model Content

[0005] This utility model provides a reusable wall-connecting device for large-span high-rise buildings, which solves the problems of hindering exterior wall construction and difficulty in reusing wall-connecting devices, and facilitates exterior wall construction and the reusability of wall-connecting devices.

[0006] This utility model is achieved through the following technical solution:

[0007] A reusable, large-span, high-rise wall-connecting device includes U-bolts, cover plates, and extension rods;

[0008] The U-bolt is fitted with a U-shaped PVC sleeve on its outer side. The U-bolt is embedded in the frame beam. The two connecting ends of the U-bolt extend out of the outer side of the frame beam and are fixedly connected to the cover plate. The rear end of the U-bolt is located outside the inner side of the frame beam. Multiple transversely distributed short steel pipes are fixed on the cover plate.

[0009] The extension members are vertically distributed and connected to the inner uprights of the outer scaffolding via horizontally distributed connecting steel pipes.

[0010] Furthermore, the cover plate is provided with bolt holes that allow the two connecting ends of the U-bolt to pass through, and the outer side of the cover plate is provided with a bolt baffle that allows the two connecting ends of the U-bolt to pass through. The two connecting ends of the U-bolt are fixed by mounting nuts to the cover plate and the bolt baffle.

[0011] Furthermore, the cover plate comprises a galvanized steel sheet, and one end of the transverse short steel pipe is vertically welded to the front side of the cover plate.

[0012] Furthermore, two U-bolts are connected to a cover plate.

[0013] Furthermore, the extension rod and the transverse short steel pipe, the extension rod and the connecting steel pipe, and the connecting steel pipe and the inner upright of the outer frame are all detachably connected by double right-angle fasteners.

[0014] The beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] 1. By placing the wall ties on the exterior of the building, the construction of the exterior walls is prevented from being hindered by the wall ties, and the risk of water seepage caused by poor sealing of the openings in the exterior walls is reduced. U-shaped PVC sleeves are fitted onto the U-bolts and pre-embedded in the frame beams. After the wall ties are removed, the U-shaped PVC sleeves are cut open, the U-shaped bolts are removed, and they can be reused, reducing construction costs and saving resources.

[0016] 2. By setting extension members, the problem of difficulty in setting up wall ties for large-span, high-rise buildings is solved. Compared with common wall tie setting methods, the structure is simple and the safety performance is high.

[0017] 3. The extension members are connected to the horizontal short steel pipes, the extension members are connected to the connecting steel pipes, and the connecting steel pipes are connected to the inner uprights of the external scaffolding through double right-angle couplers, which improves the load-bearing capacity of the wall tie device and simplifies construction;

[0018] 4. The outer side of the cover plate is provided with a bolt baffle that allows the two connecting ends of the U-bolt to pass through. The two connecting ends of the U-bolt are fixed to the cover plate and the bolt baffle by assembly nuts, which can ensure the stability and firmness of the cover plate connection and greatly improve safety.

[0024] like Figure 1 As shown in the figure, this embodiment discloses a reusable large-span high-rise wall-connecting device, which mainly includes U-bolts 2, cover plates and extension rods 6.

[0025] A U-shaped PVC sleeve 1 is fitted over the outside of the U-bolt 2. The U-bolt 2 is pre-embedded in the frame beam, with its two connecting ends extending beyond the outer surface of the frame beam. The rear end of the U-bolt 2 is located outside the inner surface of the frame beam. This design facilitates the later removal of the U-bolt 2. In this embodiment, the U-bolt 2 has a diameter of 8mm and a strength grade of 8.8. The U-shaped PVC sleeve 1 is fitted over the U-bolt 2 and fixed to the beam reinforcement by wire bonding. After the frame beam is poured and the formwork is removed, the prepared cover plate is fixed to the frame beam (also known as the concrete beam) using the U-bolt 2, nut 3, and bolt stop 11.

[0026] like Figure 2As shown, the cover plate is welded from a galvanized steel sheet 4 and transverse short steel pipes 5. The galvanized steel sheet 4 is 500mm long, 300mm wide, and 15mm thick. Two transverse short steel pipes 5 are fully welded along the center line of the galvanized steel sheet 4. The center of the transverse short steel pipes 5 is 100mm and 400mm away from the top edge of the galvanized steel sheet, respectively. Four bolt holes 10 are drilled in the galvanized steel sheet. The bolt holes 10 are 170mm away from the top and bottom edges of the galvanized steel sheet and 50mm away from the left and right edges. The upper and lower bolt holes 10 form a group, and the bolt holes in the same group allow the two connecting ends of the U-bolt 2 to pass through. At the same time, a bolt baffle 11 is installed on the outside of the cover plate to allow the two connecting ends of the U-bolt 2 to pass through. The two connecting ends of the U-bolt 2 are fixed to the cover plate and the bolt baffle 11 by mounting nuts 3.

[0027] The extension members 6 are vertically distributed and connected to the inner uprights 8 of the outer scaffolding via multiple horizontally distributed connecting steel pipes 7. By using extension members, the problem of difficult wall ties for large-span, high-rise buildings is solved. Compared with common wall tie installation methods, the structure is simpler and has higher safety performance. In this embodiment, both the horizontal short steel pipes 5 and the extension members 6 are made of coupler-type steel pipes with a diameter of 48mm and a wall thickness of 3mm. The horizontal short steel pipes 5 and the extension members 6, as well as the extension members 6 and the inner uprights 8 of the outer scaffolding, are connected and fixed using right-angle double couplers 9. The bolt tightening torque should not be less than 40 N·m and should not exceed 65 N·m.

[0028] The main application scenario of this embodiment is that the wall tie device can be used when the column spacing is greater than the horizontal spacing of the wall tie and the structural floor height is greater than the vertical spacing of the wall tie, making it difficult to install the wall tie; and when the construction requires that the wall tie installation cannot hinder the construction of the exterior wall.

[0029] By installing the wall ties on the outside of the building, the installation of the wall ties can avoid hindering the construction of the exterior wall and reduce the risk of water seepage caused by poor sealing of the openings in the exterior wall.

[0030] After the scaffolding is dismantled, the connecting steel pipe 7 is removed, the nut 3 on the cover plate is turned and the cover plate is removed, the U-shaped PVC sleeve 1 is cut, the U-shaped bolt 2 is removed, and the opening is repaired. The removed cover plate, U-shaped bolt 2 and nut 3 can be reused, which reduces construction costs and saves resources.
