Abstract
A kind of timber structure reinforcement process step based on vacuum suction method is to coat fluid sealant in timber structure area peripheral edge to be reinforced, and glass fabric, terylene release cloth and water conservancy diversion ethene screen cloth are spread successively;Vacuum bag is then covered with, resin inlet and bleeding point are set, vavuum pump is opened and vacuumizes, when the full vacuum bag of the vinylite stream in plastic holding device, allows the abundant wetting fibre of internal resin, after vinylite fully solidifies, to tear off complete after terylene release cloth and reinforce.The present invention is realized by the flowing and infiltration of vinylite reinforce timber structure using fibre reinforced composites cloth, the fibre reinforced composites cloth that this method reinforces timber structure can carry out fibrous layer numerical control system as needed, and the reinforcing face that can preferably fit, suitable for the reinforcing of complex-curved timber structure, great advantage is can be with global formation and without glue water clock, simply, easily operation, non-environmental-pollution, cost are relatively low for its technique, and the timber structure interface mechanical characteristic after reinforcing is excellent.
Description
Technical field
The present invention relates to timber structure reinforcement process, especially a kind of timber structure reinforcement process based on vacuum suction method.
Background technology
Timber structure has that high-strength light weight, unit weight are small, manufacture is easy, energy-saving and environmental protection, durability and anti-seismic performance it is good etc. excellent
Point, in China, although newly-built timber structure is less with respect to other structures, but still suffers from the Gu of certain proportion timber structure or post and panel structure
There is some in Old building, these structures larger Historic preservation to be worth, it is necessary to keep its Historic original appearance.Timber structure is due to corrosion
With infested or working service is improper or purposes changes and needs reinforcement and repair, the traditional reinforcement means of wooden component has increase to constrain
Method, Enlargement of Section, set up pull bar and set up the methods such as pin.
Fibre reinforced composites (Fiber Reinforced Polymer, abbreviation FRP) are by fibrous material and matrix
Material is mixed and by the high-performance novel structural material of certain process combining formation, with high-strength light, resisted by a certain percentage
The remarkable advantages such as tired, corrosion-resistant and construction molding convenience, are used for military project and aerospace field earliest.The fibre developed in recent years
Dimension outer patch reinforcing dependence fiber is frivolous, intensity is high, and the timber structure after reinforcing does not influence outward appearance after painting coloured silk again, also hardly increases
Add weight.But taping process needs to roll epoxy isocolloid material in fiber surface, and this material can produce water clock in construction,
Environment is polluted, the especially bonding quality of structure includes all more experiences for relying on workmen of structural plane, also has cementing border
The problems such as emaciated face is glued.
The content of the invention
It is an object of the invention to provide a kind of simple to operate, low cost, non-environmental-pollution, interface mechanical characteristic after reinforcing
The excellent timber structure reinforcement process based on vacuum suction method.
The timber structure reinforcement process based on vacuum suction method of the present invention, comprises the following steps:
1st, wood structure surface is cleaned out, fluid sealant is posted in timber structure area peripheral edge to be reinforced;
2nd, according to the principle paving glass fabric that timber structure region to be reinforced is thick, side is thin, and spread successively terylene release cloth with
Water conservancy diversion ethene screen cloth;
3rd, vacuum bag is then covered with, vacuum bag is connected with the fluid sealant of timber structure area peripheral edge to be reinforced, and sets resin inlet
And bleeding point, check the air-tightness of vacuum bag, it is ensured that vacuum bag spaced apart regions air-tightness is good;
4th, add the curing agent of 1-3% ratios to vinylite and stir, pacify between resin inlet and plastic holding device
Fill PE pipes, set on PE pipes resin to inject valve, bleeding point is connected by PE pipes with resin trap, resin trap and meanwhile with
Vavuum pump is connected;
5th, resin injection valve is closed, after opening vavuum pump is vacuumized, then resin injection valve is opened, when the second in plastic holding device
During the full vacuum bag of ene based resins stream, vavuum pump is closed, the abundant wetting fibre of internal resin is allowed;
6th, after vinylite fully solidifies, the reinforcing that timber structure region to be reinforced is completed after terylene release cloth is torn off.
The timber structure reinforcement process based on vacuum suction method of the present invention, is realized by the flowing and infiltration of vinylite
Timber structure is reinforced using fibre reinforced composites cloth, the fibre reinforced composites cloth that this method reinforces timber structure can be according to need
Carry out fibrous layer numerical control system, and the reinforcing face that can preferably fit, it is adaptable to the reinforcing of complex-curved timber structure, great advantage
Being can be with global formation and without glue water clock, and simply, easily operation, non-environmental-pollution, cost are relatively low for its technique, and after reinforcing
Timber structure interface mechanical characteristic it is excellent.

Embodiment
A kind of timber structure reinforcement process based on vacuum suction method, comprises the following steps:
1st, wood structure surface is cleaned out, fluid sealant 11 is posted in the area peripheral edge of timber structure 10 to be reinforced;
2nd, according to the principle paving glass fabric 12 that the region of timber structure 10 to be reinforced is thick, side is thin, and the terylene demoulding is spread successively
Cloth 13 and water conservancy diversion ethene screen cloth 14;
3rd, vacuum bag 15 is then covered with, vacuum bag 15 is connected with the fluid sealant 11 of the area peripheral edge of timber structure 10 to be reinforced, and sets tree
Fat inlet 5 and bleeding point 6, check the air-tightness of vacuum bag 15, it is ensured that the spaced apart regions air-tightness of vacuum bag 15 is good;
4th, the curing agent of 1-3% ratios is added to vinylite 1 according to environment temperature and stirred, and load plastic holding device 2
In, installed between resin inlet 5 and plastic holding device 2 and set resin to inject valve 3 on PE pipes 4, PE pipes 4, bleeding point 6 passes through
PE pipes 4 are connected with resin trap 7, and resin trap 7 is connected with vavuum pump 9 simultaneously;
5th, resin injection valve 3 is closed, after opening vavuum pump 9 is vacuumized, then resin injection valve 3 is opened, when in plastic holding device 2
