Abstract
The invention relates to a method for producing a wall with building waste, which is characterized in that filler in a main wall is made of building waste particles instead of common yellow sand, so that yellow sand sources are saved, the weight of the produced wall is reduced, and the thermal insulation effect is enhanced; the filler in the main wall is no longer made of adhesive, mainly cement, and accordingly consumption of cement is halved; the building waste particles are made into the filler mass, and accordingly the key to production of the wall is to quickly and conveniently adhere the building waste particles; and existing formulas of cements are complex and high in cost, foaming agent simple in matching and easy in mixing is used in the method, and accordingly the foaming agent is especially applicable to adhesion of building waste particles and the strength of the produced wall is enhanced.
Description
Technical field
The present invention relates to a kind of method of utilizing building waste to prepare body of wall, belong to building material technical field.
Background technology
Building waste be meant construction, unit in charge of construction or individual to all kinds of buildings, structure, pipe network etc. build, lay or remove, in the repairerment process produce dregs, spoir, abandon material, surplus mud and other discarded objects.The quantity of China's building waste has accounted for the 30%-40% of municipal refuse total amount.Standard with 500-600 ton/ten thousand square metre calculates that to the year two thousand twenty, China also will increase about 30,000,000,000 square metres of building area newly, and the new building waste that produces will be a shocking numeral.Yet; Overwhelming majority building waste is without any processing; Just transported to countryside or rural area by unit in charge of construction, air storage or landfill consume pork barrels such as a large amount of land acquisitions takes, refuse collection expense; Simultaneously, clear with stacking process in drop with problems such as dust, sand-lime fly upward and caused the serious environmental pollution again.
The main methods of China's building waste is with under its landfill at present.Its harm is: 1. take a large amount of soils.2. cause serious environmental to pollute.3. destroy soil texture, cause ground settlement.
For solving above technical problem, Chinese patent CN201386346 discloses a kind of heat insulation walling of light heat insulation that utilizes the building waste foaming, it is characterized in that in the middle of one deck be the building waste foaming layer, above with the bottom surface two-layer be hardstanding; Foaming layer is the light material that forms with the building waste foaming.Though be mentioned to the intermediate layer in this patent is the building waste foaming layer, in manual, does not specify this foaming layer and how to form, and the technician in present technique field can not be realized.
Chinese patent CN101054275 discloses a kind of polymerization foam concrete cement blowing agent, is grouped into though specifically put down in writing the one-tenth of blowing agent in the manual, in application; We can find: " make foamed concrete plate, section bar, tubing with polymerization foam concrete cement blowing agent and can be used for the steam curing of foam concrete steam equipment; foam concrete was put into the steam-cured 6-10 of steam equipment hour, and temperature is controlled at 50-1200 ℃, makes foamed concrete plate, section bar, tubing fast "; Obviously; Making construction wall in the building waste as this blowing agent is applied to, also need long curing time just can get a desired effect, still is that the equipment employing all has certain limitation from manufacturing cycle; The site operation difficulty is unfavorable for applying on a large scale.
Summary of the invention
To above technical problem, the present invention provides a kind of method of utilizing building waste to prepare energy-saving heat-insulating wall.
Technical scheme of the present invention is following:
A kind of method of utilizing building waste to prepare body of wall, step is following:
1) building waste is screened, classifies, the brick that screens in the building waste, stone and concrete waste material are ground into 0.5-1.5 purpose waste material particle;
2) make two rebar cylinder mould skeletons: reinforcing bar is processed two rectangle grid sheets, be connected the rebar cylinder mould skeleton that two W-shaped steel muscle between the rectangle grid sheet constitute with network-like space structures;
3) earlier a rebar cylinder mould skeleton is placed on the position that needs vallum; Rebar cylinder mould skeleton and peripheral frame trestle, beam anchor draw fixing; Then the polystyrene plastics plate is placed on a side of rebar cylinder mould skeleton; Another rebar cylinder mould skeleton is arranged on the position of vallum, makes the polystyrene plastics plate of two rebar cylinder mould skeletons in the middle of clamping; Penetrating the polystyrene plastics plate with steel wire links together two rebar cylinder mould skeletal fixation; Draw another rebar cylinder mould skeleton and peripheral frame trestle, beam anchor fixing;
4) by weight,, mix, stir 20-30 and add blowing agent 0.3-0.5 part during second, continue to stir 40-30 second, get filling mixture cement 15-20 part, waste material particle 80-85 part;
Described blowing agent weight portion consists of white glue with vinyl 35-45 part, bubble flower alkali 15-25 part and 107 glue 30-50 parts;
5) filling mixture that step 4) is stirred is inserted in two rebar cylinder mould skeletons described in the step 3), is frozen into the main wall body;
6) spring, summer: the airing of the described main wall body of step 5) after 4-6 days, is smeared cement mortar 2.5cm on the surface of main wall body, form topping, finally make body of wall; Autumn, winter: the airing of the described main wall body of step 5) after 10-12 days, is smeared cement mortar 2.5cm on the surface of main wall body, form topping, finally make body of wall.
Step 2) spacing between two rectangle grid sheets described in is 6cm,
The thickness of the polystyrene plastics plate described in the step 3) is 5cm.
Set by step 5) described method is inserted filling mixture in two rebar cylinder mould skeletons, and the body of wall height of making when needs adopts order from lower to upper in the rebar cylinder mould skeleton, to insert filling mixture during less than 3 meters; When the body of wall of needs making surpasses 3 meters; Be that unit is divided into a plurality of intervals from the bottom to top with the rebar cylinder mould skeleton with 3 meters earlier; Order is filled a plurality of intervals from bottom to top; The filling of accomplishing district's rebar cylinder mould skeleton need be to its of short duration solidifying, setting time: solidified in spring, summer 1.2-1.5 hour; Solidified in autumn, winter 4-5 hour; After treating of short duration the solidifying of rebar cylinder mould skeleton in an interval, again the rebar cylinder mould skeleton between its top adjacent region is inserted filling mixture.
Method of the present invention, its improvements are:
1, the filler in the main wall body is not only practiced thrift the yellow sand resource, and the body of wall overall weight of processing is alleviated by the general yellow sand of building waste waste material particle replacement, and the heat preservation and soundproof effect strengthens;
2, the filler in the main wall body is main adhesive with cement no longer, and the consumption of cement reduces 1/2;
3, owing to adopt building waste waste material particle as filling main body; Can therefore quickly and easily building waste waste material particle is bonded to and become the key of making body of wall together: the adhesive formula that prior art adopted be complicated; Cost is high; And the blowing agent that has used proportioning to be simple and easy to allocate in the inventive method is specially adapted to the bonding of building waste waste material particle, and the intensity of the body of wall of processing is increased.
