[0028] Traditional way needs to set preformed part in concrete wall 1 during installing scaffold 3, or completely penetrates concrete wall 1, but for the scene when concrete wall 1 is thicker, it is inconvenient to operate by penetrating way, at the same time, the workload of later repair is larger, and the construction cost is higher, the scheme adopts the way of setting blind hole on concrete wall 1, and does not need to punch through concrete wall 1, the position accuracy of plug rod 7 is guaranteed by the fastening of expansion bolt 4 to ensure that synchronous board 5 is stressed at multiple positions, because concrete wall 1 needs to meet the requirements of technical index during construction, only when synchronous board 5 abuts against the outer side wall of concrete wall 1, it can keep relative vertical state with the ground, which stably guarantees the position accuracy of plug rod 7, so as to facilitate the conversion of installation datum to adapter frame 2 through the conversion of datum, and then scaffold 3 can be better installed and fixed through clamping assembly 10, the overall installation precision is high, and the effect is good.
[0029] As Figure 6 In the preferred scheme, the outer side of concrete wall 1 is symmetrically provided with second blind hole 102, a plurality of first blind holes 101 are provided on the outer side of second blind hole 102 in the circumferential direction, first round stick 701 is inserted into second blind hole 102, synchronous board 5 is fixed with concrete wall 1 through expansion bolt 4, and expansion bolt 4 is arranged in first blind hole 101.
[0030] Plug rod 7 is a conversion point, during installation, it is installed into second blind hole 102 in the way of alignment knocking according to needs, because synchronous board 5 can guarantee position accuracy, at the beginning, synchronous board 5 keeps a certain gap with concrete wall 1, after first round stick 701 is completely installed into second blind hole 102, synchronous board 5 is locked, at this time, synchronous board 5 and first round stick 701 are fully fixed on concrete wall 1.
[0031] As Figures 7-8 In the preferred scheme, first round stick 701 and second round stick 702 are provided with step 705, the middle part of synchronous board 5 is provided with second through hole 501, second round stick 702 is inserted into second through hole 501, the outer side of synchronous board 5 is provided with a plurality of first ear plates 502 in the circumferential direction, and first ear plates 502 are fixed with concrete wall 1 through expansion bolt 4.
[0032] The outer diameter of the first round bar 701 is greater than the second round bar 702, through the above setting, the first round bar 701 can be completely pressed in the concrete wall 1 by the synchronous plate 5, and the expansion bolts 4 at multiple positions and angles are stressed, the load is uniformly distributed, the overall rigidity is strong, and the bearing capacity is sufficient.
[0033] In the preferred scheme, two second ear plates 703 are symmetrically arranged on the outer side of the first round bar 701, a third through hole 704 is arranged through the second ear plate 703, and a third blind hole 103 is arranged on the two sides of the second blind hole 102. The lock pin 8 is arranged in the third through hole 704 and the third blind hole 103.
[0034] Through the arrangement of the ear plate 703, the first round bar 701 can be further locked after being installed in place, and the problem of poor fixing effect due to the error in the manufacture of the second blind hole 102 is avoided. The lock pin 8 is made of steel and can be directly knocked into the concrete wall 1.
[0035] In the preferred scheme, the end of the alignment rod 202 is provided with a disc 201, and the disc 201 and the synchronous plate 5 are respectively provided with a plurality of first through holes 204 and third threaded holes 504 in the circumferential direction. The fastening pin 6 is arranged in the first through hole 204 and the third threaded hole 504.
[0036] Since the synchronous plate 5 is stably fixed on the concrete wall 1 by the expansion bolts 4 and the nuts, at this time, the synchronous plate 5 serves as a mounting base to lock the disc 201 on the adapter 2, which is convenient to operate and has good locking effect.
[0037] In the preferred scheme, the mounting hole 208 is arranged in the disc 201 and the alignment rod 202, and the second round bar 702 is threadedly connected with the alignment rod 202.
[0038] The threaded connection mode has better overall connection effect and stronger bearing capacity. When the alignment rod 202 is rotated to a suitable angle, the first through hole 204 is used to lock the third threaded hole 504, and then the fastening pin 6 is locked again, which is stable and convenient to use.

In actual construction, the outer diameter of the alignment rod 202 is slightly smaller than the inner diameter of the steel pipe of the scaffold 3, so as to play a role in ensuring the installation accuracy during the installation of the scaffold 3, and the coaxiality is high. At the same time, the specification of the adapter frame 2 can be flexibly adjusted according to the size of the inner cavity of the steel pipe of the scaffold 3, so as to ensure that the alignment rod 202 and the inner diameter of the steel pipe are matched, and the overall versatility is high and the effect is good.

[0044] Through the arrangement of the circular arc pressing plate 1001, the surface of the steel pipe of the scaffold 3 is abutted, and the cooperation of the two circular arc pressing plates 1001 radially constrains the steel pipe, avoiding the deflection and shaking of the steel pipe on both sides, so as to cooperate with the ring groove 206 on the adapter frame 2 to lock in two directions, and the fixing effect is good. In use, the position adjustment of the screw rod 1003 is completed by rotating the rotating rod 1008, so that the circular arc pressing plate 1001 is attached to the outer wall of the steel pipe of the scaffold 3.
[0045] In the preferred solution, the outer side of the circular arc pressing plate 1001 is provided with a cylinder 1002, the outer side of the screw rod 1003 is provided with a convex ring 1004, the screw rod 1003 is inserted into the cylinder 1002, the outer side of the cylinder 1002 is threadedly connected with a lock sleeve 1005, the lock sleeve 1005 is provided with a fourth threaded hole 1006 and a fourth through hole 1007 arranged through the lock sleeve 1005, the inner diameters of the fourth threaded hole 1006 and the fourth through hole 1007 are matched with the outer diameters of the cylinder 1002 and the screw rod 1003 respectively, and the lock sleeve 1005 is pressed on the convex ring 1004.
[0046] Through the above setting, the screw rod 1003 does not drive the circular arc pressing plate 1001 to rotate when rotating, thereby avoiding the change of the position and angle of the circular arc pressing plate 1001, even the problem of interference with the scaffold 3 during the process of installing and fixing the scaffold 3, convenient operation, good use effect, and the specification of the circular arc pressing plate 1001 can be adjusted according to the needs, the installation of the scaffold 3 with different outer diameters is met, and the universality is high.
