Referring to FIG. 1 and FIG. 2 , the present embodiment discloses an external wall scaffolding connecting wall piece, which includes a channel steel 1 with a downward opening, a connecting rod 2, a bolt 3 and a steel pipe 4. The channel steel 1 is buckled at the On the upper end of the upper turning beam 5, at least one connecting rod 2 is connected to the side plate of the channel steel 1 outside the upper turning beam 5, and the end of the connecting rod 2 away from the channel steel 1 extends into the steel pipe 4 and is fixed to the steel pipe by bolts 3. 4, the end of the steel pipe 4 away from the channel steel 1 is fixed on the scaffolding pole 7 through the fastener 6; before installation, one end of the connecting rod 2 is connected to the channel steel 1, and the other end is connected to the steel pipe 4. When installing the channel steel 1. It is directly buckled on the upper turning beam 5, and there is no need to pre-embed short steel pipes before the upper turning beam 5 is poured. It is easy to install and improves the installation efficiency, and the channel steel 1 can also be on the upper turning beam 5 along the upper turning beam 5. Move in the axial direction to ensure that the steel pipe 4 can be vertically connected to the scaffolding pole 7, and prevent the positional deviation of the embedded short steel pipe from affecting the vertical connection between the steel pipe 4 and the scaffolding pole 7; when the connecting wall is removed later, the groove can be directly connected The steel 1 is taken out from the upper turning beam 5, which can not only be reused and reduce the cost, but also be dismantled quickly and conveniently, thereby improving the construction efficiency.

In this embodiment, the number of the connecting rods 2 is two, and they are arranged in parallel along the horizontal plane. One end of the connecting rod 2 is fixed with a screw rod 21 which is matched with the through hole. The screw rod 21 extends into the channel steel 1 through the through hole and is fixed on the channel steel 1 through the first nut 8 .

Further, a first washer 9 is also sleeved on the screw 21 between the first nut 7 and the side plate of the channel steel 1 .

The bolts 3 are double-headed bolts, and the bolts 3 pass through the side wall of the steel pipe 4, the connecting rod 2 and the other side wall of the steel pipe 4 in turn along the radial direction of the steel pipe 4, and the bolts 3 on the outside of the steel pipe 4 have both ends. The second nut 10 is locked and fixed, and through the above arrangement, the steel pipe 4 can be rotated up and down finely with the bolt 3 as the rotation axis, so as to adapt to the sinking of the scaffold within the design allowable range.

Further, a second washer 11 is also sleeved on the bolt 3 between the second nut 10 and the steel pipe 4.

Further, the opening width of the channel steel 1 is slightly larger than the width of the upper turning beam 5 to ensure that the channel steel 1 can be normally snapped on the upper turning beam 5, but will not affect the channel steel 1 on the upper turning beam 5. Stability, the height of the channel steel 1 is less than the upper turning height of the upper turning beam 5 and more than half of the turning height, ensuring that the top plate of the channel steel 1 can fit on the top surface of the upper turning beam 5, increasing the stress area, Improve the stability of the channel steel 1, and the force on the open side of the channel steel 1 to the upper turning beam 5 is less than half of the upward turning height of the upper turning beam 5, preventing the stress on the upper turning beam 5 when the height of the channel steel 1 is too low. damage.

The working principle of this embodiment is: before installation, the screw rod 21 of the connecting rod 2 is passed through the through hole on the channel steel 1 and fixed by the first nut 8, the other end of the connecting rod 2 is extended into the steel pipe 4, and then bolts are used 3 Pass through the side wall of the steel pipe 4, the connecting rod 2 and the other side wall of the steel pipe 4 in turn along the radial direction of the steel pipe 4, and lock and fix the two ends of the bolt 3 outside the steel pipe 4 by the second nut 10 to form a connecting wall piece; During installation; the channel steel 1 at one end of the connecting wall piece is directly buckled on the upper turning beam 5, and the channel steel 1 is moved according to the position of the scaffolding pole 7, and then the steel pipe 4 at the other end of the connecting wall piece passes through the buckle The fitting 6 is fixed on the scaffolding pole 7 to complete the installation of the connecting wall; when the connecting wall is removed in the later stage, the fastener 6 between the steel pipe 4 and the scaffolding pole 7 is now opened, and the connecting wall is directly removed from the top. Taking out the turning beam 5, not only can be reused and cost is reduced, but also dismantling is quick and convenient, and the construction efficiency is improved.
