It is integrally formed knockdown sunpender；
B, on the outer tube wall that chimney bottom assembles annular hanging scaffold and annular hanging scaffold is made to be sleeved on chimney, the one ends wound of wirerope
On climbing device, the other end of wirerope is fixed on knockdown sunpender, and annular hanging scaffold is by climbing device along wirerope
It is lifted up；
C, to concreting is carried out between template and chimney outer wall, annular hanging scaffold is gradually above mentioned and is carried out to chimney outer wall piecewise
It pours, until annular hanging scaffold is above mentioned to chimney top and completes pouring for chimney top；
D, after pouring, annular hanging scaffold is fallen into ground and is removed, then remove the anchor ear and sunpender of chimney top again.
Compared with prior art, the beneficial effects of the present invention are:
The present invention is reinforced instead of the mode that traditional scaffold climbs, short construction period, and reduces construction personnel's
Security risk reduces the cost of Strengthening Chimney outer wall.
Further, the preferred embodiment that the present invention uses is:
Climbing device is provided in supporting beam, one end of wirerope is fixed on climbing device, and the other end is fixed on sunpender.
Anchor ear is provided with the first anchor ear and the second anchor ear, and the first anchor ear is placed in the top of the second anchor ear, and the first anchor ear is circumferential
Setting is there are six upper hanger, and the second anchor ear corresponds to upper hanger position, and circumferentially there are six lower sunpender, upper hanger and lower sunpenders pair for setting
It should connect to form knockdown sunpender.
Supporting beam is ring structure, and supporting beam is provided with 3 by the Inside To Outside of annular hanging scaffold.
There is guardrail in the inner side and outer side of annular hanging scaffold respectively.

Specific embodiment:
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to attached drawing: a kind of bracing means of tall and big concrete chimney outer tube wall is made of, ring annular hanging scaffold 8 and anchor ear
The bottom of shape hanging scaffold 8 is provided with 3 annular supporting beams 801, and the diameter of supporting beam 801 is by annular 8 Inside To Outside of hanging scaffold
It is sequentially increased, bottom plate 802 is provided in supporting beam 801, the inner side and outer side of annular hanging scaffold 8 is respectively arranged with guardrail 9, and climb dress
It sets and is mounted in supporting beam 801.
The top of chimney 1 is separately installed with the first anchor ear 2 and the second anchor ear 5, and the first anchor ear 2 is placed in the upper of the second anchor ear 5
Side, the first anchor ear 2 is circumferential to be evenly arranged with six roots of sensation upper hanger 3, and corresponding 3 position of upper hanger of the second anchor ear 5 is circumferentially there are six settings
Lower sunpender 4, each upper hanger 3 connect to form knockdown sunpender with corresponding lower sunpender 4.
Annular hanging scaffold 8 is connect with sunpender by wirerope 6, and for the one ends wound of wirerope 6 on climbing device, the other end is solid
It is scheduled on knockdown sunpender.
Template of the inside assembling reinforcement and installation of annular hanging scaffold 8 for pouring.
A kind of reinforcement means of up to concrete chimney outer tube wall, carries out as follows:
