The method of making cement rockery bonsai

Cement-plastic rockery refers to the artificial rockery made of modern materials such as concrete, FRP, organic resin and non-stone materials such as lime, brick and cement. Plastic hill and plastic stone can save the process of quarrying and transporting stone, the shape is not limited by stone, and the volume can be large or small.

The steps of making cement rockery are as follows:

The first step: the main keel should be built, the material used should be based on the size of the rockery, generally angle steel, channel steel and so on, if necessary, the process of building the main keel should be built at the same time scaffolding, this process to achieve the overall load-bearing and rocking capacity, to be firm

The second step: build the auxiliary keel, and then weld the basic shape of the rockery with 6.0mm wire (steel bar). This process should make a basic undulating relationship.

Step 3: strengthen the connection between the auxiliary keel and the main keel with angle steel and further strengthen the main structure

Step 4: use wire to subdivide the shape encryption to the grid around the square of 15cm

Step 5: make the keel rustproof.

Step 6: wrap the steel frame with galvanized barbed wire, the mesh size is about 1cm, be careful not to overlap except the upward faces.

Step 7: add appropriate amount of paper towel ash and fiber wire with cement without mortar, mix with water and apply to the surface of barbed wire netting. This layer is difficult and easy to fall into the mesh. Adding fiber and tissue ash is to enhance adhesion and adhesion.

Step 8: after the first layer of cement is basically dry, gently apply it to the surface with 1:1 cement mortar to make the upper layer more solid.

Step 9: after this layer is slightly dry, you can paint a layer and do the surface details or texture. If you make this layer with colored cement, you don't have to do the color later.

Step 10: spray exterior wall paint and acrylic paint to make color effect after completion

Step 11: dismantle the scaffolding, clean the battlefield and evacuate the scene.

The method of making rockery is not difficult, but if you want to make a more realistic and beautiful rockery, you have to make it with the help of professional rockery production personnel. Arranging rockery at home can not only decorate and beautify the home, but also play a certain role in fengshui.

The method of making cement rockery:

1. Positioning and setting-out: according to the general construction plan, the site is arranged, the road is unblocked, the site is investigated, the elevation and the relationship with the surrounding buildings are checked, and the construction scope is determined.

2. Bottoming: setting out, opening line, digging earthwork and pouring concrete cushion to lay the foundation.

3. Embedment of embedded parts: when embedded parts are located on the upper surface of cast-in-place concrete, there are three fixed ways according to the size and function of embedded parts.

The main results are as follows: (1) the size of the flat plate embedded part is small, and the embedded part can be directly tied to the main steel bar, but its position should be observed at any time in the process of pouring concrete, so that the problem can be solved in time.

(2) the angle steel embedded parts can also be directly tied to the main reinforcement. In order to prevent the vibration of the concrete under the embedded parts from being compacted, the embedded parts should be drilled for exhaust during concrete construction before being fixed.

(3) during the construction of embedded parts with large area, in addition to being fixed with anchor bars, appropriate specification angle steel should be welded on the upper part of the embedded parts to prevent the displacement of embedded parts, and drill holes to exhaust air on the anchor plate if necessary. For extra-large embedded parts, vibrating holes must be drilled on the anchor plate to vibrate concrete, but the location and size of the drill hole can not affect the normal use of the anchor plate.

4. skeleton welding production: the skeleton structure includes brick structure, steel frame structure and the mixed structure of the two. The brick structure is simple and economical, and steel frame cantilevers should be used for the parts with great changes in the shape of the mountain. The waterfalls, flowing springs and reserved green caves in the mountains should be waterproof to the skeleton structure.

5. Steel mesh welding production: small steel bars are laid on the formed skeleton and welded, fixed and modeled with an electric welding machine. This step can basically determine the basic shape of the rockery.

6. Tie up the barbed wire mesh: spread the wire mesh on the steel frame that has been built, and then bind and fix it with small steel wire.

7. Plastering: the mud bottom is molded with cement, yellow mud and river sand to form a highly malleable mortar on the built skeleton. Repeated processing, so that the shape, texture, plastic body and surface scratches are basically close to the model.

8. Modeling: the plastic surface carefully depicts the texture, color, texture and surface features of the stone on the plastic surface. Texture and color according to the design requirements, stone powder, color powder according to the appropriate proportion of white cement or ordinary water powder into mortar, according to rough, smooth, hair and other plastic surface treatment. In the shaping of texture, generally speaking, the mountains and rocks dominated by straight lines and supplemented by horizontal patterns are more able to show a steep, straight and straight posture; the mountains and rocks dominated by horizontal lines and supplemented by straight lines are more able to express the image of chic and bold; the mountains and rocks with comprehensive patterns are more able to show deep and magnificent features. In order to enhance the natural reality of the mountain and stone scenery, in addition to the texture description, it is also necessary to do a good job in the details of the natural characteristics of the mountain and rock, such as cracks, holes, holes, rotten, cracks, faults, displacement and so on.

9. Pigment surface oil: color setting is carried out when the moisture of the plastic surface is not dry, and the basic tone is mixed well with pigment powder and cement with water, and dyed layer by layer. Sprinkle a slightly darker tone on the stone seam hole or shade corner, and when the plastic surface is 90% dry, sprinkle a few green, black or white spots of different sizes and densities in the depression to enhance the three-dimensional and natural sense.
