The content of the invention
For problems of the prior art, the present invention provides a kind of method for repairing and mending of ancient city wall brick, by only part
Damaged ancient city wall brick is reused after being repaired, and the ancient city wall brick and second-hand brick looks after repairing are basically identical.
To reach above-mentioned purpose, technical scheme is as follows:
A kind of method for repairing and mending of ancient city wall brick, it is characterised in that comprise the following steps:
1) dust, mud scum and chip on ancient city wall brick surface are cleaned up using natural flows;
2) the ancient city wall brick after will be clean is placed in be dried shady and coolly so that ancient city wall brick moisture control is in 15-25%;
3) drilled in breakage, the quantity of drilling is controlled in every 1cm2Damaged area bores a hole, in drill bit when brill
Surface coating butter, old butter will be wiped by often boring a hole, and painting is covered with new butter;
4) the filling binding material in drilling, the binding material that filling is completed will partly protrude drilling;
5) filled and struck off after binding material in breakage filling and repairing putty, and by the surface of repairing putty rapidly;
6) after consolidation shaping in putty surface to be repaired, in the repairing putty external coating fabric struck off;
7) the ancient city wall brick that repairing is completed can be obtained after natural air drying.
The diameter control of drilling in 2mm, drilling it is deep-controlled apart from breakage surface 8-10mm.
The binding material is by weight:21.5 parts of portland cement, 22.8 parts of quartz sand, ethane-acetic acid ethyenyl ester is common
Poly- 5 parts of emulsion, 0.5 part of cellulose ether, 0.2 part of water reducer, 50 parts of water.
The repairing putty is by weight:21.5 parts of portland cement, 12 parts of quartz sand, 14 parts of land plaster is dispersible
2 parts of rubber powder, 0.5 part of wood fibre, 50 parts of water.
The fabric is by weight:10 parts of blue bricks powder, 8 parts of activated carbon, 10 parts of epoxy resin, 12 parts of cement, water 60
Part.
Progressively the method for repairing and mending is illustrated below:
Natural flows are used when the 1st, being rinsed to city-wall brick, it is to avoid use High-Pressure Water, because city-wall brick is in itself
Through breakage, the breakage of city-wall brick can be aggravated using High-Pressure Water;
2nd, city-wall brick moisture control is kept to be the key that subsequent step can be carried out in 15-25%, if moisture content mistake
Height can cause the binding material subsequently filled, repairing putty etc. not to play a role normally, if moisture content is too low, in boring procedure
In to be likely to result in city-wall brick damaged;
3rd, the purpose of drilling is to be used to fill binding material, and binding material can preferably bond repairing putty and ancient city wall brick
Together, it is to avoid mend comes off under external force;The original creation that butter is the present invention is coated when drilling, it is acted on
It is to have two, one is that damaged Old City Wall intensity itself is very low, if directly with bit bore, it may appear that ancient city
The appearance of the problems such as comminuted rupture of wall brick or disconnection, by way of coating butter on drill bit, it is possible to reduce during drilling
Shake and to the frictional force of city-wall brick, it is to avoid the comminuted rupture of city-wall brick, another effect is that butter has certain bonding force,
The chip produced during drilling is directly glued to be brought out on butter, it is to avoid the step of rushing chip with water again.
4th, the main function of binding material is by repairing putty and city-wall brick bonding, binding material composition of the present invention
The bonding of repairing putty and city-wall brick is specific to, the purpose of binding material convex drilling is so that itself and repairing putty contact surface
Product increase, so that with stronger cohesive force.
5th, repairing putty of the present invention is the improvement carried out on the basis of binding material, and the property of binding material is close,
Therefore both adhesions are stronger.
What the 6th, fabric was creative employs blue bricks powder, after blue bricks powder and activated carbon mixing wall brick can be made to have naturally
Antiquated sense, it is no longer necessary to follow-up individually does old step.
The technique effect that the present invention has:The ancient city wall brick can not repaiied Chu Lai has stronger antiquated sense, and mend energy
It is enough lasting to be bonded on the wall brick of ancient city, it will not be come off because of external force or weathering.
Embodiment
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, present invention specific examples below
Illustrate, but the present invention is limited to absolutely not these examples.
Experimental example 1
Take certain build ancient city dismounting old city-wall brick repaired, using natural flows by the dust on ancient city wall brick surface,
Mud scum and chip are cleaned up;Ancient city wall brick after will be clean is placed in be dried shady and coolly so that ancient city wall brick moisture control exists
15-25%;In breakage drilling, the quantity of drilling is controlled in every 1cm2Damaged area bores a hole, in drill bit when brill
Surface coats butter, and old butter will be wiped by often boring a hole, and painting is covered with new butter;The diameter control of drilling is in 2mm, drilling
It is deep-controlled apart from breakage surface 8-10mm.Binding material is filled after the completion of drilling in drilling, the bonding completed is filled
Material will partly protrude drilling;Binding material is by weight:21.5 parts of portland cement, 22.8 parts of quartz sand, ethane-acetic acid ethyenyl
5 parts of ester copolymer emulsion, 0.5 part of cellulose ether, 0.2 part of water reducer, 50 parts of water.Fill rapid in breakage filling after binding material
Repairing putty, and the surface of repairing putty is struck off;Repairing putty is by weight:21.5 parts of portland cement, quartz sand 12
Part, 14 parts of land plaster, dispersible 2 parts of rubber powder, 0.5 part of wood fibre, 50 parts of water.After consolidation shaping in putty surface to be repaired,
The repairing putty external coating fabric struck off;The fabric is by weight:10 parts of blue bricks powder, 8 parts of activated carbon, epoxy resin
10 parts, 12 parts of cement, 60 parts of water.The ancient city wall brick that repairing is completed can be obtained after natural air drying.
Through comparing, the ancient city wall brick after repairing, from basically identical in appearance, will have been repaired in addition with complete ancient city wall brick
Ancient city wall brick after is placed under natural environment, is observed through 1 year, to find there is mend obscission.
Although by referring to the preferred embodiments of the present invention, invention has been described, this area it is common
It will be appreciated by the skilled person that various changes can be made to it in the form and details, without departing from appended right
The spirit and scope of the present invention that claim is limited.
