Description
Technical field
The present invention relates to construction wall construction fields, and in particular to a kind of thin cloth of fibre reinforced cement base and filling wall are compound
Structure and its construction technology.
Background technique
Wall self-insulation refers to according to certain architectural construction, makes wall using self-insulation wall material and mating mortar
The physical indexs such as thermal property meet a kind of wall body structure of energy saving building standard requirements.Engineering practice proves to apply this kind of wall
Technology can not only reduce building energy conservation incremental cost, but also the quality for improving Energy Conservation Project in Construction is with highly important
Meaning.Currently, wall self-insulation material therefor is broadly divided into compound structural, is sintered class and three kinds of non-sintered class.
Compound structural self-heat conserving is that thermal insulation structure is added among wall body structure, forms Composite Enclosure Structure, feature
It is that thermal and insulating performance is good, batch production degree height, quick construction, is conducive to large-scale promotion application.It is sintered class wall self-insulation
Material includes mud sintering energy-saving tile, shale tailing modulus brick etc., wherein mud sintering energy-saving tile with rivers, lake, sewage at
Manage mud caused by factory etc. and be used as primary raw material, and mix a large amount of available industrial residues and special admixture is sintered and
At raw material are widely distributed, and have the characteristics that energy conservation, section soil, benefit are useless.Non-sintered class wall self-thermal insulation material has aerating mixed
Solidifying earth building blocks, composite heat insulation block etc..It is base stock that air-entrained concrete building block, which is by cement, lime, flyash or quartz sand,
Through building block made of pouring molding steam press maintenance.Composite heat insulation block is to be embedded in lightweight in the heat transfer path of all kinds of building-blocks
Thermal insulation material forms energy-saving hollow building, according to the difference of the thickness of building block, pass and composition material, the intensity and biography of masonry
Hot coefficient is adjustable.It is saved at present in In China Coastal Areas, such as Jiangsu, Shanghai, Shandong, Zhejiang etc., application is wide
Self-insulation wall material be air-entrained concrete building block, mainly have steam pressure sand aerated concrete block and aerated coal ash mixed
Solidifying earth building blocks two major classes.
Air-entrained concrete building block has many advantages, such as lightweight, heat preservation, heat-insulated, fire-retardant, can manufacture different size
Building block, plate and heat insulating products have become one of main material of self heat insulation wall, are especially a kind of in hot-summer and cold-winter area
The preferred material of good materials for wall and frame structure self-heat conserving filling wall.But using based on air-entrained concrete building block
The self-heat conserving of body material fills wall, since building block strength of materials itself is low, surface porosity easily loses powder, mortar bonding when causing to build
Power is low, and when painting is also easy to produce hollowing, cracking, or even removing falls off equal qualitative problems of construction.In addition, in use due to wind
Blow solarization, temperature change and the wall body slit that generates also is always the main problem for perplexing engineering circles.Occur in use
Crack, not only influences the state of appearance of self-heat conserving filling wall, but also will lead to the reduction of its bearing capacity, durability variation, and drop
The service life of parapet body.Due to the above problems, the application range of this kind of self-thermal insulation material is hindered, especially in frame
Application on frame structure outer wall.
The crack of the self-heat conserving filling wall of material is mainly had following by its Crack cause based on air-entrained concrete building block
Several types: (1) it thermal cracking: expands with heat and contract with cold now since air-entrained concrete building block itself is easy to appear under the action of the temperature difference
As, and it is different from the linear expansion coefficient of armored concrete, so that the shrinkage of two kinds of materials is also different when temperature change.Cause
This, it is easy to lead to occur more apparent stress variation in corresponding wall body structure, finally in air-entrained concrete building block structure
Crack is formed, especially in different materials junction, such as crack of Vierendeel girder, column and door and window corner is most commonly seen.(2)
Desciccation crack: during air-entrained concrete building block constructing operation, with the reduction of its interior moisture content, itself is necessarily possible to
The problems such as will appear more apparent contraction distortion, also just likely results in the generation of crack problem.Blockwork after drying shrinkage,
It after encounteing water or be affected with dump in the natural environment and expands, is shunk again then as masonry drying, generated at weak position
Drawing crack seam.Fractue spacing caused by this kind of contraction distortion is wider, and the position of serious cracking is predominantly located at filling wall and beam, column and cuts
The connecting portion of power wall.(3) it design and construction crack: since the design of dependency structure is unreasonable, is either answered in locally building
Power calculates aspect, and there is apparent defect and failures, finally would necessarily affect the construction effect of air-entrained concrete building block, split
Seam problem occurs therewith, and bring crack occurs mainly in some complex regions in terms of this design and construction, for example, with beam, column
Junction, door, window hole edge etc..(4) constructing operation crack: since working procedure, duration arrange unreasonable also to easily cause
Wall crazing brings some apparent crack hidden danger, and still than relatively straightforward, menace is also bigger for the influence of this aspect.
It is nonstandard in each application link processing of the constructing operation level for air-entrained concrete building block, it is likely to will lead to its appearance
Crack problem.For example, plastering is uneven if block surfaces are uneven, it is also easy to produce contraction unevenly, also will form hollowing and open
It splits.
Fiber reinforcement technology refer to metallic fiber, inorganic non-metallic fiber, synthetic fibers or natural organic fiber according to
Certain weaving method forms a kind of technology that knitmesh is used to enhance the substrates such as concrete.Currently, this enhancing technology is applied to
Concrete substrate is the most mature, has significant effect in terms of mitigating concrete structure crack, improving.Fiber
Net is combined with cement base be formed by the substrates such as composite material and concrete, masonry between have better compatibility, harmony and
Interpenetrating property, and anti-aging, high temperature resistant, durability are more preferable.
Generally speaking, research and application of the fiber reinforcement technology in terms of concrete material and its component are more, theoretical
Also relative maturity.It is also a kind of effective mode that existing structure is reinforced and repaired using fiber reinforcement technology, not only be can be improved
The development of the bearing capacity and shock resistance, limiting structure crack of component, and hardly increase the self weight of component.
Currently, by fiber reinforcement technology be applied to masonry wall material in research with apply it is relatively fewer, for example, only right
Fabric enhancing performance, fiber reinforced micro porous light concrete sandwich building block, fabric enhance brick setting shear behavior in construction wall
Etc. done some researchs.It is existing to self-heat conserving filling wall reinforcement means also to some extent there is with the wall service life not
The disadvantages of synchronization, complicated construction technique or cost are higher, durability is undesirable, consolidation effect is general.Therefore, to self-insurance
While considering that structure overall security is met the requirements, be also considered as construction technology can for the determination of temperature filling wall reinforcement means
Strength performance raising, reinforcing engineering overall cost, the length for reinforcing the duration, reinforcing use function to original after operability, reinforcing
Influence, the building factors such as beauty.

Specific embodiment
It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of embodiment of the present invention
Attached drawing be briefly described, it should be understood that the following drawings illustrates only certain embodiments of the present invention, therefore is not to be seen as
It is the restriction to range, it for those of ordinary skill in the art, without creative efforts, can be with root
Other relevant attached drawings are obtained according to these attached drawings.
Since the application of frame structure filling wall is still in a dominant position, in conjunction with new material, the development of new technology, formed certainly
Heat-preserving wall composite construction is the main path for improving the performances such as its heat preservation, cracking resistance, antidetonation.Currently, for air entrained concrete
The method that the self-heat conserving filling wall of material is reinforced based on building block is mainly the following.
1, it is reinforced using high performance lightweight aggregate concrete
This kind of method, which refers to, anchor bar net and smears certain thickness water as required in the side of original wall or two sides
Cement mortar surface layer, so that steel mesh undertakes collective effect with original wall by the bonding of mortar surface layer, it is original for improving
The anti-seismic performance of brick wall body, it is most commonly seen in practical masonry bearing capacity engineering at present.Its major advantage is that thickness is thin,
Small on original scantling and dead load influence, tension, compression strength are high, and the old and new's interfacial adhesion is good, shrink small.
2, fibrous composite is pasted to reinforce
Pasting fiber reinforced is a kind of wall reinforcement method that scientific and technological content is relatively high, and this fiber reinforced method will not influence
Architectural appearance can effectively improve the anti-seismic performance and shear-carrying capacity of door-window opening walling, be primarily adapted for use in fired common brick
The flat shear in plane of wall is reinforced and seismic hardening, should also there is the sqtructural adhesive to match when reinforcing using fibrous composite.Its
Advantage mainly have it is high-strength it is efficient, corrosion-resistant, do not increase member dead weight etc., be mainly used in the reinforcing of brick wall.
3, armored concrete board wall, constructional column, stem, collar tie beam is added to reinforce
This method is to add certain thickness reinforced concrete wall in the one or both sides of original wall body, to improve holding for original wall
Loading capability and anti-seismic performance, armored concrete board wall generally use prefabricated, are attached by being in the milk or selling strong with masonry wall, and
Improve the holistic resistant behavior of masonry structure by newly-increased stem, constructional column or collar tie beam, major advantage be anti-seismic performance compared with
It is good.
4, mortar surface layer part fillet method for strengthening
The thinking of this kind of method is diagonally to arrange oblique reinforcing bar, Mei Geyi in the expected X-shaped wall body area for crack occur
Set a distance arranges distributing reinforcement perpendicular to oblique reinforcing bar, then by reinforcing bar through walls with crotch realize the drawknot between reinforced mesh with
And reinforcing bar and wall are reliably connected, and spread mortar surface layer.Its advantage is that reinforcing scope is narrow, materials more save, to preventing from filling
Wall diagonal crack, which is carried out, has more specific aim, is mainly used in the reinforcing of brick wall.
Although cracking, bearing capacity and durability deficiency etc. that existing reinforcement means can improve self-heat conserving filling wall are asked
Topic, but there is also some defects.For example, the major defect of high performance lightweight aggregate concrete reinforcement means is construction technology
Complexity needs to be layered plastering, and time-consuming, long construction period, construction quality is difficult to ensure, requires strength classes of mortar high.
Phenomenon is lost since the presence of metope reinforcing bar also results in heat bridge, reduces self-heat conserving performance.
The major defect for pasting fibrous composite reinforcement means is cost height, and non-refractory needs fit structure glue
It is used together；In addition, CFRP Sheet Strengthening Method complicated construction technique, the factor for influencing consolidation effect is more, for example, fiber cloth is used
Amount, fiber cloth bonding method, fiber cloth paste the number of plies, wall depth-width ratio, adhesive glue and anchor type etc..
Adding armored concrete board wall and constructional column, stem, collar tie beam reinforcing major defect is complicated construction technique, scene
The wet construction time is long, and construction period is longer, and shape to structure and geometric dimension have larger change, the bearing capacity width of raising
Degree is little.In addition, heat bridge is easy to cause to lose phenomenon, and it is easy to happen and temperature occurs with the wall of concrete junction and split
Seam.
Mortar surface layer part fillet method for strengthening complicated construction technique, the quality that reinforcing bar is connect with wall is difficult to ensure, right
The inhibition and consolidation effect for filling wall diagonal crack need further to study, and are primarily adapted for use in the reinforcing of brick wall.
To sum up, it can be seen that it is existing to self-heat conserving filling wall reinforcing or enhancing technology can not effectively act as heat preservation,
The effects of cracking resistance, antidetonation, be it is secondary, inventor provide a kind of thin cloth of fibre reinforced cement base and filling wall composite construction and its apply
Work technique, it is intended to which the enhancement method for optimizing self-heat conserving filling wall improves the antidetonation and endurance quality of self-heat conserving filling wall, expands light
The use scope of matter heat insulation building block material.
The thin cloth of fibre reinforced cement base is made of concrete base material and fibrous web two parts, is that a kind of dipping is full
The soft cloth-like thing of cement, hydration reaction can be occurred and harden by meeting water.Its way is that cement powder is passed through fabric in advance
Porous surface is filled into fabric, sealant is applied in textile surface after filling is closely knit, so that cement powder will not leak out.It uses
Before, such composite construction can be cut randomly, and cover the surface of arbitrary structures just as soft cloth.In use, only needing
Spray or add water to the surface of thin cloth, can curing molding, hardening then forms answering for durability and excellent in mechanical performance later
