Abstract
The invention discloses a cast-in-situ gypsum hollow wall in the field of building construction. The cast-in-situ gypsum hollow wall comprises the components of, by weight: 60-75% of gypsum, 5-15% of cement, 10-20% of fly ash, and 2-8% of lime. The invention also discloses a preparation method of the hollow wall. According to the invention, a wall template is arranged on an inner support and an outer support; pre-embedded parts such as electrical conduits, junction boxes, and door and window wood bricks are arranged on the template; a plurality of water bags are arranged in the inner support; the materials are well mixed by stirring, and the mixture is delivered into the template through a pipeline; when the wall is hardened, water in the water bags is drawn out, and the water bags are fetched; ports left by the water bags are sealed; a rest section of template without cast wall is installed, and casting is carried out until the top is reached; and when the wall is hardened, all the templates are removed. According to the invention, the surface of the wall is smooth and flat. The wall is light and green, and has the functions of sound insulation and heat insulation. The strength of the wall is high, and the wall is prevented from cracking. The construction is convenient and simple, a mechanization degree is high, and labor intensity is low. With the method, construction cost is reduced.
Description
Technical field
The present invention relates to a kind of body of wall and preparation method thereof, the specifically cast-in-situ gypsum hollow wall in building operation, also relates to the preparation method of this body of wall, belongs to building field.
Background technology
At present, in building operation, the filled with masonry of skeleton construction, generally adopts the various building blocks such as air-entrained concrete building block, gypsum block, and GRC wallboard etc., in building process, need a large amount of labor forces, and labour intensity is large, and effect is low, and construction cost is high.Build by laying bricks or stones completely, need on metope, whitewash the whitewash mortar that 10-20mm is thick, just can carry out surface layer finishing.Owing to whitewashing the common fault of quality, cause cracks on wall surface, need often reprocess, cause the time-consuming waste of Denging.The built-in fitting such as various conduits, terminal box in masonry need in body of wall, slot burrow pre-buried, it is very inconvenient that each work post coordinates, to the processing at fluting place not in place, easily cause wall crazing, built-in fitting position does not meet the disadvantages such as drawing requirement, even affects the quality of successive projects.
Summary of the invention
Task of the present invention is to provide a kind of cast-in-situ gypsum hollow wall, and the preparation method of this body of wall is also provided.
For realizing above-mentioned task, technical solution of the present invention is:
Cast-in-situ gypsum hollow wall, is made up of the component of following weight per-cent: gypsum 60%-75%, cement 5%-15%, flyash 10%-20%, lime 2-8%.
The method of described cast-in-situ gypsum hollow wall, comprises the steps:
(1) wall form is arranged on the inside and outside support of template, support is apart from the bottom of the beam of building or retain a bit of distance at the bottom of floor;
Wherein inner support evenly arranges along short transverse;
The built-in fittings such as conduit, terminal box, door and window woodbox are wherein set in template;
(2) multiple water pockets that are filled with water are set in the inner support of wall form;
(3) material therefor is added in stirrer at the scene successively, after stirring, send in template by pipeline;
(4) after the gypsum wall sclerosis of first pouring into a mould, extract the water in water pocket out, take out water pocket, the mouth that shutoff water pocket stays;
(5) template of that a bit of distance retaining at the bottom of the beam of locating distance building or at the bottom of floor again, once-cast is at the bottom of beam or at the bottom of floor;
(6) until after after the gypsum wall sclerosis of cast, remove whole templates.
After testing, indices meets the testing requirement of national standard JG/T169-2005 to body of wall of the present invention.
The present invention has the following advantages:
Surface of wall is smooth, smooth, and than general masonry light weight, sound-insulating, can regulate indoor humidity, environmental protection, plasters without carrying out wall plaster again, can directly carry out facing decoration.Strength of wall body is high, does not ftracture, and the built-in fitting one-step installation such as various conduits, terminal box put in place; Construct simple and direct, mechanization degree is high, and labour intensity is low, has reduced construction cost.
Embodiment
Example 1, cast-in-situ gypsum hollow wall material therefor and consumption thereof, 600 kilograms, gypsum, 120 kilograms of cement, 200 kilograms, flyash, 80 kilograms, lime.
The method of cast-in-situ gypsum hollow wall:
Wall form is installed, and the outer support of a pair of symmetry of template adopts sizing Assembled stand, and support can be according to the height of body of wall, length arbitrary combination, and support retains 200mm at the bottom of the beam of building.Template inner support length is design wall thickness, and height 100mm installs one group of inner support along each meter of left and right of body of wall short transverse, the reserved circular hole that can wear bolt of inner support, by bolt by firm two side template drawknots.The built-in fittings such as conduit, terminal box, door and window woodbox are fixed in template with double sticky tape, and reality is all criticized with gesso in all gaps, ensures in the time building not spillage material.
Water pocket is installed, multiple water pockets are installed equably in the inner support of wall form, slowly water filling, water fills rear sealing.
Cast, adds material therefor in stirrer at the scene successively, after stirring, slowly sends in template by pipeline, after the gypsum wall sclerosis of first pouring into a mould, extracts the water in water pocket out, takes out water pocket, the mouth that the sheet material shutoff water pocket made from light material stays.
The template of the 200mm height retaining at the bottom of the beam of locating distance building again, once-cast is at the bottom of beam, until after after the gypsum wall sclerosis of cast, remove whole templates, construction completes.
Example 2, method be with example 1, material therefor and consumption thereof: 750 kilograms, gypsum, 130 kilograms of cement, flyash double centner, 20 kilograms, lime.
Example 3, method be with example 1, material therefor and consumption thereof: 700 kilograms, gypsum, 50 kilograms of cement, 200 kilograms, flyash, 50 kilograms, lime.
Example 4, method be with example 1, material therefor and consumption thereof: 650 kilograms, gypsum, 150 kilograms of cement, 170 kilograms, flyash, 30 kilograms, lime.
