Abstract
The present invention relates to a kind of restorative procedures of Reconstruction Project holding member, comprising steps of one: the decoration and coating layer of removal holding member surface package, until substrate exposes hard firm concrete interface；Step 2: the processing of concrete base layer dabbing derusts to the reinforcing bar of exposing, corrodes the reinforcing bar that serious reinforcing bar welds same specification again after derusting；Step 3: fracture carries out pressure grouting processing；Step 4: shaft concrete is repaired；Step 5: then the jewel hole bar planting on retaining column is layered in shaft and smears polymer mortar.The present invention solves the reparation problem for retaining structure in Reconstruction Project, improves service life.
Description
Technical field
The present invention relates to a kind of restorative procedures of Reconstruction Project holding member.
Background technique
It often can be using the holding member in existing building as the characteristic mark to the engineering in Reconstruction Project engineering
And souvenir, certain historical trace is remained with, the style and features of old site building before making common people remain to recall out to original building.But make
For history preserved building, all it is often that is existing of the remote past, also lives through many wind and rain and wash away, can suffer from severe
The erosion and destruction of nature or man-made environment, the intensity of holding member, rigidity stability and durability, safety etc. cannot
Meet the requirement of new construction, holding member in such Reconstruction Project to be made still to continue to survive number together with new building
Ten or upper a century acquire a certain degree of difficulty.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of restorative procedure of Reconstruction Project holding member is provided, is solved
The reparation problem for certainly retaining structure in Reconstruction Project, improves service life.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of restorative procedure of Reconstruction Project holding member, it is characterised in that it includes the following steps:
Step 1: the decoration and coating layer of removal holding member surface package, until substrate exposes hard firm coagulation pedosphere
Face；
Step 2: the processing of concrete base layer dabbing derusts to the reinforcing bar of exposing, corrodes serious reinforcing bar after derusting again
Weld the reinforcing bar of same specification；
Step 3: after component Surface layer's concrete is cut, if inner concrete discovery has crack, first fracture is carried out at pressure grouting
Reason；
Step 4: if the larger damage of shaft concrete local damage volume is heavier, reparing process are as follows: surface dabbing, clear water punching
It washes, supporting module, is poured high-intensitive self-compacting concrete or grouting material, form removal, maintenance；
Step 5: after having repaired shaft concrete, the jewel hole bar planting on retaining column, bar planting spacing 200mm, implantation depth is reinforcing bar
The 15d of diameter is retaining column two layers of reinforced mesh of package after bar planting, and mesh sheet bar diameter is 6mm.Then it is layered and smears in shaft
Polymer mortar, lift height are not more than 15mm.
The restorative procedure of the Reconstruction Project holding member, it is characterised in that: poured in step 4 high-intensitive from close
The intensity of real concrete is not less than C35.
The restorative procedure of the Reconstruction Project holding member, it is characterised in that: polymer mortar is smeared in step 5
Intensity be not less than C30.
The beneficial effects of the present invention are: solving the reparation problem of holding member, increase its service life, replicability is strong.
Specific embodiment
A kind of restorative procedure of Reconstruction Project holding member, it includes the following steps:
Step 1: the decoration and coating layer of removal holding member surface package, until substrate exposes hard firm coagulation pedosphere
Face；
Step 2: the processing of concrete base layer dabbing derusts to the reinforcing bar of exposing, corrodes serious reinforcing bar after derusting again
Weld the reinforcing bar of same specification；
Step 3: after component Surface layer's concrete is cut, if inner concrete discovery has crack, first fracture is carried out at pressure grouting
Reason；
Step 4: if the larger damage of shaft concrete local damage volume is heavier, reparing process are as follows: surface dabbing, clear water punching
It washes, supporting module, (intensity for pouring high-intensitive self-compacting concrete is not less than for the high-intensitive self-compacting concrete of casting or grouting material
C35), form removal, maintenance；
Step 5: after having repaired shaft concrete, the jewel hole bar planting on retaining column, bar planting spacing 200mm, implantation depth is reinforcing bar
The 15d of diameter is retaining column two layers of reinforced mesh of package after bar planting, and mesh sheet bar diameter is 6mm.Then it is layered and smears in shaft
Polymer mortar (intensity for smearing polymer mortar is not less than C30), lift height is not more than 15mm.
It should forbid to operate using big machinery, avoid using manually column Surface layer's concrete is retained using small machine chisel
Big vibration causes disturbing influence to lattice column.Wire brush, blast cleaning supernatant layer dirt can be used, then cut not close
Real concrete is until solid firm concrete, exposes former member reinforcing steel bar.
The measures such as covering, watering, thin film moisturizing, spraying or brushing curing agent can be used in maintenance.
In the reservation base for post primary coat brush or spraying interfacial agents dug out, in favor of conjunction old and new concret.
When being laid with steel mesh, vertical reinforcement should lean on cylinder and be propped with steel bar end.Steel mesh external protection thickness is not less than
The gap of 15mm, reinforced mesh and cylinder is not less than 10mm.
