In basement exterior walls, where short pipes are not convenient to reserve, short rebars are reserved. The steel pipes of the steel pipe coupler-type external scaffolding and the short rebars are connected by welding. Whether it is the reserved short pipes or the short rebars, the connection with the steel pipes of the steel pipe coupler-type external scaffolding is relatively complex and time-consuming.

[0010] Preferably, the diameter of the top plate 1 is larger than the diameter of the sleeve, and the diameter of the sleeve is equal to the diameter of the top plate 2.

[0011] By adopting the above technical solution, the ribs enhance the strength of the top plate 1 and the sleeve, the top plate 1 increases the contact area between the sleeve and the concrete wall, and enhances the stability of the connection.

[0012] Preferably, one end of the screw is threadedly connected to a nut, and the nut is overlapped on a side of the block away from the sleeve, and the screw and the block are both located inside the concrete wall.

The screw and the block are poured through the concrete and remain in the concrete wall. The sleeve and the end of the screw exposed outside the concrete wall are screwed in until one side of the top plate is close to the concrete wall. The sleeve and the rod of the wall frame are then connected through the rotating fastener to complete the connection between the concrete wall and the wall frame. The three-stage waterstop bolt is conducive to enhancing structural stability and reducing safety hazards. At the same time, the threaded connection and the fastener clamping reduce installation time and speed up construction.

[0020] 2. A detachable connection is provided between the sleeve and the wall connecting frame of this device. After removing the rotating fastener, the sleeve is screwed out of the screw, and the wall connecting frame is moved away. Finally, the screw protruding from the concrete wall is cut off with a tool. Compared with cutting off the short steel bars and the wall connecting frame once after welding, and then cutting off the steel bars protruding from the concrete wall once, this is conducive to improving the construction speed, simplifying the construction process, and increasing the construction speed;

[0021] 3. The sleeve and the outer rod of the screw of this device can be rotated to adjust the position and can be disassembled for repeated use.

By adjusting the position of the block, the length of the screw entering the concrete wall can be changed, which is convenient for adapting to different concrete wall thicknesses.

[0029] The following is combined with Figure 1-4 The utility model is described in further detail.

[0030] The embodiment of the utility model discloses a connecting piece for an external scaffolding wall connecting piece.

[0031] Reference Figure 1 、 Figure 2 , including a concrete wall 1, a three-section waterstop bolt 2, a wall connecting frame 3 and two rotating fasteners 4 (known technology), one end of the three-section waterstop bolt 2 is fixedly connected to the inside of the concrete wall 1, and the blocking block 23 of the three-section waterstop bolt 2 is located inside the concrete wall 1, which can prevent the three-section waterstop bolt 2 from detaching from the concrete wall 1 after being stressed. The other end of the three-section waterstop bolt 2 is clamped on the wall connecting frame 3 through two rotating fasteners 4. The two rotating fasteners 4 can be opened and locked, which is convenient for disassembly of the connection between the three-section waterstop bolt 2 and the wall connecting frame 3, so that the three-section waterstop bolt 2 can be reused. The concrete wall 1 is connected to the wall connecting frame 3 through the three-section waterstop bolt 2. Compared with traditional electric welding, it simplifies the construction process and improves the construction speed.

[0032] Refer to 3. Figure 4 The three-section water-stop bolt 2 includes a screw 21, a sleeve 22 and a block 23. The sleeve 22 is a national standard internal thread sleeve. The internal thread of the sleeve 22 is connected to the outer surface of the screw 21, that is, the sleeve 22 can rotate on the outer surface of the screw 21. The sleeve 22 is reusable, which is beneficial to reduce material usage and labor costs and improve economic benefits. The inner part of the block 23 fits the outer surface of the screw 21. The sleeve 22 and the block 23 are respectively located at both ends of the screw 21. After the formwork of the concrete wall 1 is removed, the sleeve 22 is threadedly tightened with the screw 21. The sleeve 22 uses a rotating fastener 4 to connect the steel pipe rod of the wall frame 3 to the sleeve 22.

[0033] Reference Figure 1 、 Figure 3 、 Figure 4 The two ends of the sleeve 22 are fixedly connected with the top plate 1 5 and the top plate 2 6 respectively. The top plate 1 5 and the top plate 2 6 protect the two ends of the sleeve 22 to prevent the sleeve 22 from being damaged when used improperly with the concrete wall 1 and the two rotating fasteners 4, thereby preventing damage to the sleeve 22 and thus damaging the screw 21. When the sleeve 22 is screwed on the outer surface of the screw 21, the top plate 1 5 is tightly attached to the concrete wall 1, and the top plate 2 6 protects the other end of the sleeve 22. One side of the top plate 1 and one end of the sleeve 22 are fixedly connected with a plurality of ribs 7 in a circular array along the outer surface of the sleeve 22. The screw 21 passes through the interior of the top plate 1 5 and the top plate 2 6.

[0034] The diameter of the top plate 5 is larger than the diameter of the sleeve 22, which increases the contact area between the top plate 5 and the wall, enhances the structural stability, and reduces safety hazards. The diameter of the sleeve 22 is equal to the diameter of the top plate 2 6, saving the material of the top plate 2 6 and reducing the material usage cost.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 One end of the screw 21 is threadedly connected to a nut, and the nut is overlapped on the side of the block 23 away from the sleeve 22. The nut limits the movement of the block 23 to prevent the block 23 from separating from one end of the screw 21. The screw 21 and the block 23 are both located inside the concrete wall 1. The distance from the block 23 to the two ends of the screw 21 can be adjusted by turning the nut. The distance from the block 23 to the two ends of the screw 21 is different according to the thickness of the concrete wall 1.

[0036] Reference Figure 1 、 Figure 2 、 Figure 3 The wall connecting frame 3 includes several rods, which are steel pipes. The corresponding rods and the outer surfaces of the sleeve 22 are clamped into the inside of the two rotating fasteners 4. The two rotating fasteners 4 are arranged linearly along the length direction of the sleeve 22. The sleeve 22 and the wall connecting frame 3 are respectively located in the two clamps of the rotating fastener 4.

[0037] Reference Figure 3 、 Figure 4 The internal thread of the block 23 is connected to the outer surface of the screw 21. By rotating the thread, the position and direction of the block 23 are changed to adapt to the thickness of the concrete wall 1.

[0038] The implementation principle of the connecting piece of an external scaffolding wall connecting piece in the embodiment of the present utility model is as follows:

[0039] 1. Twist the nut to adjust the position of the block 23. The screw 21 and the block 23 are cast through the concrete and remain inside the concrete wall 1. Screw the sleeve 22 and the end of the screw 21 exposed outside the concrete wall 1 into the concrete wall 1 until one side of the top plate 5 is in close contact with the concrete wall 1. Then, use the rotating fastener 4 to connect the sleeve 22 and the rod of the wall connecting frame 3, thereby completing the connection between the concrete wall 1 and the wall connecting frame 3.

[0040] 2. If the connection between the concrete wall 1 and the wall frame needs to be dismantled, it is only necessary to remove the rotary fastener 4, unscrew the sleeve 22 out of the screw 21, move away from the wall frame 3, and finally use a tool to cut off the screw 21 protruding from the concrete wall 1. Compared with cutting off the short steel bars and the wall frame 3 once after welding, and then cutting off the steel bars protruding from the concrete wall 1 once, the construction process is simplified and the construction speed is increased.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
