Description
Technical field
The present invention relates to a kind of method of reinforcing masonry, especially relate to a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member.
Background technology
Masonry structure is a kind of traditional form of structure; China is existing in a large number in labour masonry structure building; Wherein many masonry structures must carry out reinforcement and strengthening effectively to it owing to factors such as in use damage, aging and disaster cause many problems that influence safety and function of use such as member cracking, bearing capacity deficiency.The requirement that the masonry house structure adding layer is transformed or the change of function of use etc. make that the bearing capacity of original structure is not enough, need improve bearing of component through the method for reinforcing.The a large amount of valuable historical relics of China belong to masonry structure, wooden construction or post and panel structure in addition, because the time is remote, have all received damage in various degree, also must adopt reasonable method to carry out reinforcement protection.
The masonry structure dead weight is bigger, the less method of increase of should taking during reinforcing to conduct oneself with dignity.Though the encased steel plate reinforcing method is little to the deadweight influence, improve the excessive waste that causes on the contrary owing to reinforce the back bearing capacity, even be not beneficial to structural safety.Back member resistance to compression bearing capacity reinforced by outer sticking angle steel and rigidity all improves a lot, and reinforcement performance is good, practices thrift usage space, easy construction and easy anchoring, but owing to masonry component is not laterally receiving the performance that sufficient constraint influences vertical humidification.Laterally behind the outer wrapping fiber cloth; The masonry compressed member laterally receives sufficient constraint and helps the integrality of retaining member; Improve the energy dissipation capacity and the ductility of masonry compressed member by a relatively large margin; The easy stickup of construction party, and heat-resisting and corrosion resistance increases deadweight by force, hardly, does not change structure and shape.
Summary of the invention
The present invention solves the existing in prior technology technical problem; Provide a kind of applied widely; Organically combine angle steel reinforcing and fiber cloth reinforced advantage, angle steel can improve bearing of component and rigidity, strengthens its stability; The crack Characteristics of Development that cloth can provide enough horizontal restrain to improve the masonry compressed member; The globality of retaining member in pressurized process also can obviously improve the energy dissipation capacity of member, significantly improves the ultimate deformation ability of member; Improve ductility, help a kind of method of the antidetonation of structure with outer wrapping fiber and angle steel composite consolidation masonry compressed member.
It is to solve the existing in prior technology technical problem that the present invention also has a purpose; A kind of bearing capacity that improves compressed member is provided, has improved a kind of method of its deformation performance with outer wrapping fiber and angle steel composite consolidation masonry compressed member.
It is to solve the existing in prior technology technical problem that the present invention has a purpose again; Provide that a kind of consolidation effect is good, to reinforce reliability high; And simple to operate when reinforcing, easy construction, to scantling, deadweight increase less, do not influence production, and can reduce a kind of method of engineering cost with outer wrapping fiber and angle steel composite consolidation masonry compressed member.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals:
A kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member is characterized in that, may further comprise the steps:
Step 1 is removed masonry surface rendering layer,
Step 2, with polymer cement mortar that the surfacing of completing steps 1 is smooth;
Step 6, at masonry external coating cementing agent, spraying quartz sand forms matsurface;
Step 7 is reinforced masonry surface, back to completing steps 6 and is carried out exterior plaster.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member, in the said step 1, remove masonry surface rendering layer after, chamfered is done on the masonry surface of removing rendering layer, then processing is scrubbed on the masonry surface.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member, the surfacing of completing steps 1 is smooth in the said step 2 with polymer cement mortar, use acetone mortar surface layer again.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member; In the said step 3, before the outsourcing cloth, evenly brushing is surperficial at masonry with cementing agent earlier; And laterally behind the outer wrapping fiber cloth, again in cloth external coating one layer binder and maintenance.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member; In the said step 4; The concrete grammar of the some angle steel of outsourcing is: be the cloth surface with alcohol wash completing steps 3; The cementing agent brushing is bondd in cloth and angle steel surface, pour into cementing agent in angle steel and gap, concrete column top after the anchoring and push.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member; In the said step 5; The concrete grammar of welding batten plate is: weld batten plate in the waiting step 4 after the adhesive cures again, the batten plate two ends are fixing with angle steel welding respectively, and weld every batten plate during welding successively.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member, it is the acetone washing lotion of 95%-99% that said acetone adopts concentration.
In above-mentioned a kind of method with outer wrapping fiber and angle steel composite consolidation masonry compressed member, it is the alcoholic solution of 90%-95% that said alcohol adopts concentration.
Therefore, the present invention has following advantage: 1, applied widely, organically combine angle steel reinforcing and fiber cloth reinforced advantage; Angle steel can improve bearing of component and rigidity, strengthens its stability, the crack Characteristics of Development that cloth can provide enough horizontal restrain to improve the masonry compressed member; The globality of retaining member in pressurized process also can obviously improve the energy dissipation capacity of member, significantly improves the ultimate deformation ability of member; Improve ductility, help the antidetonation of structure; 2, utilize the easy anchoring property of angle steel, can prevent peeling off suddenly of cloth, delay the fracture of cloth, improve the utilization rate of cloth, thereby improved the bearing capacity of compressed member indirectly, improve its deformation performance through itself and cloth collaborative work.And the effect of contraction of cloth can make the longitudinal bracing effect of angle steel obtain with fully playing; 3, not only consolidation effect is good, to reinforce reliability high, and simple to operate when reinforcing, easy construction, to scantling, deadweight increase less, do not influence production, and can reduce engineering cost.
