Abstract
The utility model discloses a polymer modified cement mortar reinforcement mesh surface layer reinforcing structure, which comprises a bonding agent coating layer and a mortar layer. The mortar layer comprises a reinforcement mesh, the reinforcement mesh is connected with a pin planted into a reinforced structural boundary, and two sides of the reinforcement mesh are respectively provided with a polymer modified cement mortar bonding layer and a polymer modified cement mortar protective layer. The polymer modified cement mortar reinforcement mesh surface layer reinforcing structure can effectively increase bearing capacity of a reinforced structure, increases rigidity of the reinforced structure and is small in occupation space. A surface layer reinforcing structure after being form is reliable and tight when bonded with the reinforced structure, does not crack, is waterproof, seepage-proof, fireproof, high temperature resistant, C1-corrosion resistant, carbonization resistant and rust resistant and is fine in durability. Simultaneously, the polymer modified cement mortar reinforcement mesh surface layer reinforcing structure is simple in construction process, does not need to build formworks, is fast in increase of strength of polymer modified cement mortar, and greatly shortens work period. The reinforcing structure can be simultaneously applied to repairing and reinforcing the existing concrete structures and masonry structures, and resolves problems that materials of aged buildings are damaged and aged, and the aged buildings are insufficient in structural strength.
Description
Technical field
The utility model relates to a kind ofly repairs polymer-modified cement mortar steel mesh reinforcement surface layer ruggedized construction with reinforcement to existing building concrete or masonry structure.
Background technology
For concrete structure, the form of reinforcing has multiple, as sets up strengthening member, enlarging section reinforcing, steel-bonded reinforcement, affixing carbon fabric reinforcing and steel wire mesh-polymer-modified cement mortar surface layer and reinforce.Can improve the bearing capacity of concrete structure by above-mentioned reinforcing.But these reinforcement means and use this method and there is following defective in the ruggedized construction that produces:
1) set up the long construction period of strengthening member, and the component affecting usage space of setting up;
When 2) adopting enlarging section to reinforce, deadweight and the physical dimension of member after reinforcing all increases to some extent, and influences the attractive in appearance and usage space of building, need set up template, long construction period;
3) steel-bonded reinforcement needs to carry out strict fire prevention and antirust processing after reinforcing, and need regularly safeguard later maintenance expense height;
4) affixing carbon fabric is reinforced and not to be increased scantling, but because of carbon cloth reinforced employing epoxy resin as base material, thereby its endurance quality and fireproof performance are all relatively poor, the material price of carbon fiber is also higher on the other hand;
5) though the fireproof performance of steel wire mesh-polymer-modified cement mortar surface layer is better than carbon cloth reinforced, steel strand Master Cost height, the steel wire mesh construction is complicated, and overall expenses is higher.
For masonry structure, reinforcing commonly used mainly comprises repairs and grouting, and surface layer is reinforced, outer strutting, cornerite or fringing, support or support reinforcing etc.The defective that exists is as follows:
1) repair and bearing capacity that grouting can improve limited;
2) traditional cement screedn plays drum, cracking, easily to being in the masonry under the wet environment, the problem that seeps water in addition, leaks;
3) adopt strutting, support and support, cornerite fringing etc., long construction period, and influence usage space, local stiffening can not solve problems such as the wearing out of original structure bearing wall, breakage.
The utility model content
The technical problems to be solved in the utility model provides a kind of polymer-modified cement mortar steel mesh reinforcement surface layer ruggedized construction, can be used for the reparation and the reinforcing of concrete structure and masonry structure simultaneously, and effect is remarkable, can overcome the deficiencies in the prior art.
The utility model is by the following technical solutions:
A kind of polymer-modified cement mortar steel mesh reinforcement surface layer ruggedized construction; comprise interface agent coating and screed; described screed comprises steel mesh reinforcement; steel mesh reinforcement connects the pin of implanting in the reinforced structure interface, and the steel mesh reinforcement both sides are established polymer-modified cement mortar tack coat and polymer-modified cement mortar topping respectively.
Preferably, each layering of described ruggedized construction is arranged by the order of interface agent coating, tack coat, steel mesh reinforcement, topping.
Preferably, described interface agent coating 1 adopts polyacrylate cement based interfacial agents or water-base epoxy interfacial agents, thick 1～2mm.
Preferably, described steel mesh reinforcement is welded in length and breadth by plain bar or hot rolled ribbed steel bar.
Preferably, described pin is the hot rolling deformation reinforcing bar.
The utlity model has following technique effect:
1) reinforcing effect is good: the adhesion strength height, and firm with the reinforced structure bonding, on the interface, be not easy to occur stripping damage, feasible reinforcing surface layer and reinforced structure be co-operation well, and reinforcement performance is secure.
2) have good workability: adopt mechanical injection technology, back-up coat is more closely knit, it is more firm to combine with reinforced structure, and construction quality is more secure.Construction technology simply, does not need to set up template, the polymer-modified cement mortar gain in strength is fast, greatly the reduction of erection time.The adhesion strength height can also be used to the reinforcing of facing upward.
3) functional performance is good: do not ftracture, water proof anti-seepage, fire-proof high-temperature resistant, anti-Cl
-Burn into is prevented carbonization, resistance rust.
4) good endurance: it is closely knit to be shaped, and can use under the environment of corrosive environment, high humidity, hot environment, and ruggedized construction can reach structure design application life application life.
5) can be applied to the reparation and the reinforcing of existing concrete structure and masonry structure simultaneously; Can solve the problem of the damaged aging and structural strength deficiency of the material of old building simultaneously.
