What are the stone railings made of?

Stone railings have the advantages of beauty, fashion, environmental protection, anti-aging and no deformation, and can be widely used in municipal, water conservancy, parks, traffic roads, bridge railings and other guardrail projects. A complete stone railing consists of columns, column tops, railings, drums and mats. So what are the stone railings made of? Stone railings are mostly natural stone, and some are imitation stone railings made of concrete and stone powder. Common stone railings on the market include bluestone railings, white marble railings and granite railings. Next, I will introduce the material of stone railings and the related contents of stone railings installation. 1. What are the stone railings made of?

There are many kinds of stone railings, and all kinds of stones can be made. Common stone railings on the market include bluestone railings, white marble railings and granite railings. Generally, natural stone railings are mostly made of granite, so why is granite used so frequently?

1, rich in granite resources.

Granite is a kind of stone rich in mineral resources in China. There are many kinds of granite, such as sesame white, sesame black, yellow rust stone and so on.

2. Granite has good heat resistance.

Because stone railings are generally used in outdoor environment, especially in summer, in the south of China, it is hot and humid, and it is easy to be damaged if other stones are used. On the other hand, granite has good heat resistance. It can only expand when the temperature exceeds 700 degrees Celsius, and the normal outdoor stability will not exceed 60 degrees Celsius. Therefore, granite has strong adaptability in this respect, so you don't have to worry about the influence of the weather when making stone railings.

3. Wear resistance of granite

The wear resistance of granite is also very good in all natural stones. The so-called wear resistance of stone generally refers to the degree of wear consumption of stone under the conditions of friction, cutting and external impact. The better the wear resistance of stone, the smaller the influence will be under the condition of acting force; On the contrary, stone with poor wear resistance is easy to be damaged. For example, marble, a stone material, has poor wear resistance. If used on stone railings, it needs more maintenance to last for a long time.

4. Granite is cheap.

Granite is a kind of stone with abundant mineral resources in China, so it has great advantages in mining and transportation, in other words, it is cheaper.

Generally speaking, compared with other stone materials, granite is the first choice for making stone railings because of its low price, good performance and durability. Most stone railing manufacturers will use it, and customers will give priority to granite, which is why granite is used more in the production of stone railings.

Second, the stone railing installation operation method

1, stone baffle installation

The surface of stone baffle should be cleaned before installation. Install the lower cushion block of the baffle plate on the lower handrail according to the design position. When the gap between the pad and the handrail is large, marble glue should be used for joint filling. Before installing the stone baffle, the centerline and sideline of the component should be popped up on the column and the lower handrail to check the elevation. After placing the position line of the baffle, install it according to the pre-drawn baffle diagram. Setting slurry: Before installing the stone baffle, clean the tenon and groove of the column, brush a layer of plain cement slurry with water cement ratio of 0.5, and then install it to ensure that there is no gap between the baffle and the column.

When carrying the stone baffle, each rope must be stressed at the same time. Carefully check the stress position of the stone and then slowly put it in place, and put the selected part on the temporary support. Gently lift the stone baffle and align it with the tenon and groove of the column.

After the stone baffle is installed in place, check it carefully with the control line. If there is any displacement, pry it back and adjust the assembly to the correct position.

2. Install handrails on stone railings

Install the cushion block on the stone baffle according to the design position. When the gap between the pad and the baffle and handrail is large, marble glue should be used for joint filling. Gently lift the handrail on the stone railing and align it with the tenon and groove of the column.

3, stone railing column installation

Stay wire installation, pop-up column edge line on column base surface, and pop-up column body center line on column base surface. During installation, the crosshair on the pillar top stone should coincide with the center line of the column.

When installing the stone railing column, the tenon of the column and the tenon groove and tenon nest of the ground stone should be cleaned up. First, put a layer of plain cement slurry with water cement ratio of 0.5 on the mortise, and the thickness is about10 mm. Fill the cement slurry in the mortise of the column, and then align the column with the center line. If there is vertical deviation, the edge of mortar joint can be leveled with iron sheet. When installing a stone balustrade column, you should always check the verticality of the whole column body with a vertical ball. If there is any deviation, it should be adjusted by joint clearance, and gravity tapping is not allowed to correct it. The top of the column is fixed with nylon rope.

4. Give directions

If there is a big gap between stones, marble glue can be applied to the joints. The color of marble glue should be adjusted according to the color of stones, and white cement is the best color matching effect. If the seam is thin, smooth it with putty or gypsum; If the design has instructions, tick off the joints according to the design instructions. Mortar joint should be Gou Ping with stone components, and it is not allowed to hook into concave joint. Mortar joint should be straight, sealed and smooth.

Step 5 amend

After the installation of stone railings, check whether there is any lack of edges and corners in columns, handrails and other parts. To use marble glue and a little ordinary portland cement (color matching makes the polished stone color consistent with the original bluestone) to repair the defects of edges and corners, and carry out hard grinding to ensure the overall beauty of the stone railing.
