Description

A kind of fabric Combined concrete building block and preparation method
Technical field
The invention belongs to civil construction projects and assembling structure field, are related to building masonry material, specially a kind of fabric Combined concrete building block and preparation method.
Background technique
Building block is one of composition material of building masonry wall, has production, transport and builds advantage.Building masonry wall is general It is subjected in face and out-of-plane load, and requires have heat preservation, sound insulation, freeze proof function and durability.When normal use there is not allowed that Crack, wall should conveniently open up door-window opening, lay all kinds of pipelines.
Existing air-entrained concrete building block and light aggregate building block have the function of heat insulating and sound insulating, but due to internal sealed porosity compared with It is more, density is small, block strength is lower, and appearance has voids and pits more, easily occurs losing fangle in carrying, and water absorption rate is high, frost resistance Difference;Easily there is hollowing, falls ash, crack phenomenon in surface plastering, and wall easily cracks, and seriously affects use.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of fabric Combined concrete building block and preparation method, Concrete segment is not easy damage and crack, and frost resistance is good, and compression strength of building block is high, no hole pitted skin, flat appearance, and wall is inhibited to split Seam, matches the wall service life with main structure service life.
The present invention is to be achieved through the following technical solutions:
A kind of fabric Combined concrete building block, forms four columns of rectangular cylinder corner angle including arranging, tensioning is fastened The fabric cylinder of rectangular cylindrical structure is formed on column, and is filled in the filler inside outer fabric shell;The column it is transversal Face is in rectangle, and four column relative position fixations form lattice core cage.
Preferably, the both ends of four columns form lattice by the screw and end plate connection fixation that are fixed on end face respectively Core cage, the end plate aperture of upper end, for pouring filler.
Preferably, the fabric cylinder is wound by canvas, organic fiber or inorfil.
Preferably, the hollow parts of the filler are cylindrical, and are arranged coaxially with fabric cylinder.
Further, the hollow parts of the filler are filled with thermal insulation material.
Preferably, the filler uses air entrained concrete, light aggregate concrete or high performance concrete.
Preferably, the column uses wooden, bamboo or organic material.
A kind of preparation method of fabric Combined concrete building block, includes the following steps,
Step 1, prepared by core cage;Four columns form lattice core cage, core cage section foreign steamer by screw and end plate connection Exterior feature is used for casting filler having a size of rectangle, upper head plate aperture;
Step 2, prepared by fabric cylinder, and fabric is contacted by concrete stock tank with concrete full penetration;Fabric is played into initial line It is fixed on a root post, then keeps tension around core cage one week plus 1/4 week, terminate side and be fixed on adjacent column;Fabric Cylinder cross section outer profile size is identical as building block cross sectional dimensions, completes the production of fabric cylinder;
Step 3, fabric cylinder filler;Fabric cylinder is put into punching block, punching block cross section inside dimension and building block cross section foreign steamer Wide size is identical, and fabric cylinder is consistent with punching block height;Filler is poured into fabric cylinder from upper head plate aperture, pressurize vibration compacting, So that fabric laminating punching block inner wall;
Step 4, maintenance molding;Maintenance is pre-hardening to filler, removes punching block, continues maintenance and solidifies completely to filler, completion group Close building block production.
Further, several apertures are opened up in step 3, on punching block, the Free water outlet for filler in fabric cylinder.
Further, in step 3, round tube is placed at fabric cylinder center, in outer fabric shell and filler is poured outside round tube, is formed Hollow cavity.
Compared with prior art, the invention has the following beneficial technical effects:
The present invention has the characteristics that good water permeability using fabric, so as to reduce the ratio of mud near fabric, increases mixed Solidifying soil density reduces water absorption rate to improve block strength, improves frost resistance and thermal insulation property.It is wrapped using fabric cylinder from periphery Inner stuffing is wrapped up in, hoop constraint is provided, is formed " hoop effect ", the compression strength of building block is further improved.And due to knitting Object sheet has incubation and thermal insulation function as thermal inertia material, and cooperation filler further promotes thermal characteristic of wall.Since fabric has There is certain toughness, therefore wall has the function of damping vibration-isolating, the interference to user can be vibrated with relief features, is promoted comfortable Property.Fabric has tensile capacity, and wall has good shock resistance and cracking resistance when building materials stronger using cohesive force, To solve blockwork problem of Cracking.It is wrapped up by fabric concrete composite material, building block presentation quality is good, no honeycomb fiber crops Face, losing fangle can directly swabbing use, especially suitable for fabricated construction.Fabric blockwork good integrity, can be with Burst at the seams slot, pipeline installation, can punch a hole, and interior patch is plug-in, is easy to use.
Further, due to steel form moulding, it is ensured that building block size is accurate, and then gray seam thickness is reduced in building process, It prevents heat bridge from being formed, greatly improves the incubation and thermal insulation function of wall.
Further, due to using light filler, cooperate fabric or hollow measure, building block is light-weight, be conducive to carry and It builds, while reducing geological process inertia force, mitigate earthquake, reduce sudden strain of a muscle and slump risk outside wall.
The method of the invention wraps up inner stuffing from periphery using fabric cylinder, applies certain prestressing force by surrounding, according to Concrete cracking is prevented by fabric itself tensioning effect, and hoop constraint is provided, is formed " hoop effect ", is further improved and build The compression strength of block.Concrete is non-combustible component simultaneously, after casting concrete is hard-combustible component in fabric, improves the fire-resistance of wall Performance.Materials are convenient, and production is simple, at low cost, high-efficient, function admirable, can prefabrication scene build, also can in-situ precast Scene is built.
