Embodiment 1
[0066] This embodiment relates to a method for preparing a decorative thin-walled rammed earth wall, comprising the following steps:
[0067] 1) Wall pretreatment
[0068] a. Clean up the floating ash on the surface of the wall to be decorated;
[0069] b. Stir 1 part of wall base film and 1 part of fine sand (particle size <0.5mm) evenly for later use;
[0070] c. Use a brush to evenly brush a layer of unsanded base film on the wall;
[0071] d. After 5 minutes, brush the base film with fine sand again, wait for 24 hours, and then brush the cement base.
[0072] The concrete operation of described coatingcement base is:
[0073] a. Put 2 volumes of gray Portland cement, 4 volumes of 0.5-1mm fine sand, and 2 volumes of <0.5mm fine sand in a mixer for 1 minute, then add 1 volume of water, and stir to form Paste, to get a mixed paste, add 0.01 part of carboxymethylcellulose CMC (water reducing agent) to 1 part of mixed paste and stir evenly to get a well-mixed cement base; ...
Embodiment 2
[0090] Compared with Example 1, the difference is that in the step 3), each plate is rammed to the third layer or so, and a wire mesh with a diameter of 1 mm and 10×10 mm is placed, and the width of the wire mesh is 50 mm. cross, the distance between adjacent barbed wires is 20-25cm.
Embodiment 3
[0092] Compared with Example 1, the difference is that the sand material includes four particle sizes of <0.5mm, 0.5~1mm, 2-3mm and 3~4mm, and the volume ratio is <0.5mm, 0.5~1mm, 2-3mm and 3~4mm=0.5:1:2:4;
[0093] Prepared by the following method:
[0094] 1) Pour the sand material into the mixer first;
[0095] 2) Pour the fine hemp rope fibers (thin hemp rope fibers with a length of about 1cm and a diameter of <0.2mm) into 1.4 volumes of clear water and stir evenly; pour the above mixture into a mixer equipped with sand and stir for 2 minutes;
[0096] 3) Mix the pulverized soil and white cement, and stir the powder evenly with a mixer to obtain the powder, divide the powder into 4 parts on average, first add 1 part of the powder to the step 2) Mixer, stir for 20s, and add in 4 times. If the soil and sand are sticky in the mixer, the soil on the inner wall of the mixer should be cleaned in time.
[0097] 4) Continue stirring after adding all the powder materials, and st...

Abstract
The invention belongs to the technical field of construction, and in particular relates to a method for preparing a decorative thin-walled rammed earth wall, comprising the following steps: 1) setting fixing bolts on the surface of the wall body to be decorated, and setting angle steels in the vertical direction; A screw rod is arranged on the fixing bolt, and a thin-walled rammed-earth wall template is erected on the surface of the wall through the screw rod, and the distance between the thin-walled rammed-earth wall template and the wall is the same as the side length of the angle steel; 2 ) adding soil materials between the wall and the thin-walled rammed earth wall formwork to ram the earth wall; 3) removing the thin-walled rammed earth wall formwork and the screw rod to be attached to the wall surface The decorative thin rammed earth walls. The traditional rammed earth wall is too thick and heavy. The technical process of the present invention can obtain a rammed earth wall with a thickness of about 8cm, so that the rammed earth wall can be used as an interior decorative wall. The construction method of the present invention can effectively improve the decorative thin-walled rammed earth wall. The bonding force between the wall and the surface of the wall improves the overall strength of the thin-walled rammed earth wall.
Description
technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a method for preparing a thin-walled rammed-earth wall. Background technique [0002] The building made of raw earth materials is the evidence and treasure of the historical civilization of the Chinese nation, and it is also an important part of the rich heritage left to us by our ancestors. It has the advantages of low cost, warm in winter and cool in summer, energy saving, and integration into nature. Rammed earth construction is the most widely used raw earth construction process, but because rammed earth walls are too thick, it is only widely used in rural areas, and it is difficult to use it in large quantities in urban environments. [0003] With the emergence of the concept of green and sustainable development, raw earth materials are gradually recognized and used by everyone, among which rammed earth, a construction technique, is widely used for its uniq...
