Specific implementation mode
In conjunction with the accompanying drawings, the present invention is further explained in detail.
Historical relic's protection device for slowing down blasting vibration as shown in Figs. 1-5, historical relic is preferably imperial palace, including the first case
Type column 1, high-damping block 2, epoxy coating strand 3, anchorage 4 and the second box column 5.First box column, 1 quantity is four, respectively
Four angle points in imperial palace are set.First box column 1 includes the steel member of anchoring bogie 1-1 and support anchoring bogie 1-1
1-2, each steel member 1-2 support three anchoring bogie 1-1, anchoring bogie 1-1 to be evenly arranged along imperial palace short transverse, often
Three row's epoxy coating strands 3 are evenly arranged on a anchoring bogie 1-1, i.e., a total of three rows three beams steel strand wires, epoxy applies
Layer steel strand wires 3 are fixed by anchorage 4.Epoxy coating strand 3 is the anticorrosive prestressed material of novel high-performance, should use symbol
Close the underrelaxation steel strand wires of U.S.'s ASTMA416-92 standard productions.
With further reference to Fig. 2, high-damping block 2 there are two being arranged side by side between bogie 1-1 and imperial palace is each anchored, to
Avoid direct contact with imperial palace damage city brick.In view of the facility of construction, anchoring bogie 1-1 is steel construction, anchoring bogie 1-1
Integrally-formed with steel member 1-2, steel construction is level-one steel, shares 8 steel columns, and when design is considered as steel column and bears structure
Dead weight, anchoring bogie 1-1 bears the pulling force of external prestressing generation, and is evenly distributed to historical relic periphery, and the bottoms steel member 1-2
Portion is fixed by M20 bolts 6.Since anchoring bogie 1-1 tension tonnages are larger, it must assure that quality meets when constructing and set
Meter requires, and the anchor plate of anchoring bogie 1-1 must be vertical with prestressing tendon when installing, and positioning should be accurate.
Second box column, 5 quantity is also four, two-by-two the front and back front-back for being symmetricly set on imperial palace, the second box column 5 with
High-damping block 2 there are two being also arranged side by side between imperial palace, for imperial palace to be isolated to slow down influence of the public vibration of explosion to imperial palace.
High-damping block 2 is yielding rubber block, thickness 6cm.
First box column 1 and the second box column 5 are linked together by epoxy coating strand 3, external prestressing system
Mainly by epoxy coating strand 3, mating billet and anchorage 4, anchoring bogie 1-1, high-damping block 2 and anti-corrosion material etc.
Composition.
When slowing down the historical relic's protection device of blasting vibration using this, all steel constructions must be protected, and protection can press
Following proposal executes：
Derusting scheme：Sandblasting removes old paint film and ground corrosion, until exposing clean steel, structure or component surface are not
Must there be old paint film, rust, greasy dirt and impurity.
Application scheme：Using single layer of primer application, priming paint is high molar ratio aqueous inorganic zinc silicate（IC531）Twice（It is dry
Film overall thickness 75um）.
And when material selection, epoxy filling coating needs meet specification《Seven prestress wires of epoxy coating filled-type
Standard criterion》（ASTM A 882/A882M-02a）And《Epoxy coating strand for prestressed concrete》（ISO 14655:
1999（E））.Anchorage 4 uses externally cable Special ground tackle, performance that should meet international post-tensioned prestressing association FIP《Post-tensioned prestressing
The examination of system and application proposal》、《External prestressing material and system》And standard GB/T/T14370-2000《Prestressing force
Muscle anchorage, fixture and connector》Regulation.
The contact situation of anchoring bogie and historical relic wall should be gone through in stretching construction, before prestressed stretch-draw；Institute
It is 0.20R to state prestressed stretch-draw Stress Controlb y, using the single carry out stretching construction of small-size jack, jack form and tonnage
Ying Yuqi is consistent.It is influenced needing to pay attention to loss of prestress by root stretching construction using small-size jack, when stretching construction answers
It repeatedly mends and draws, it is ensured that every steel strand wires uniform force；Historical relic must be monitored, is examined in prestressing tendon stretching process
The situation of change in historical relic crack；After tensioning, prestressing tendon anchors active length without cutting, first can carry out again
Secondary benefit is drawn, and second can be unloaded；When tension of prestressed tendon, should there are corresponding safety measure, presstressed reinforcing steel both ends to forbid to stand
People；After presstressed reinforcing steel anchoring, when must loosen for some reason, special loosening device is preferably used to unclamp anchorage, whenever not
In presstressed reinforcing steel, there are states of tension directly to cut anchorage；Tensioning must comply with global symmetry principle.
Imperial palace periphery anchor ear needs to set up holder, and holder sets up the requirement for having to comply with corresponding specification, standard, and holder is taken
If examination is had to pass through after, can be come into operation after qualified.Since holder is set up, use, there are high-altitudes in demolishing process
Operation ensures personnel safety so must take appropriate measures.It must be provided with safety guard net on rack platform to be used cooperatively, prevent
The setting of protecting wire net must meet the requirement of corresponding specification, standard, regulation, fall danger to avoid personnel.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention should be regarded as the protection of the present invention
Range.
