For the marble railing, it is can be seen everywhere in the park, on both sides of the river, on some of the city's streets, everywhere you can see the marble railing. Marble railings are a very good protection product. They can effectively separate roads from rivers and provide good protection, especially for children and animals. Most of today's stone railings are made of marble. This is a special form of stone carvings, and it is also a stone work with artistic value. Stone railing installation methods and installation considerations are what I believe there are many people want to know.
Marble rail installation method
First, construction preparation
1, stone railings member acceptance
(1) The processed stone railings shall have no defects such as cracks, hidden defects, stains, red and white lines, stone defects, and stone iron. You can use the hammer to strike carefully. If there is a sound that sounds like a ring, it is a no-fault hidden stone railing component. If there is a crash, it indicates that the stone railing component is hidden.
(2) The direction of the stone grain should conform to the force requirements of the components. The meteorites should be oriented horizontally. Columns, corner posts, etc. should be vertical.
(3) The types, quality, processing standards, specifications, dimensions, labels, and color of stone railing components shall meet the design requirements, with factory certification and test reports.
(4) Check whether the length of the parapet of the stone railing meets the design requirements (not less than 60mm); check whether the corners, arcs or other heterogeneity components lay out the blanks according to the requirements of the drawings, and whether the processing of the irregular pattern components and the angle control are correct.
2, stone railings should be done before the installation of technical work
3. Check the cable to meet the design requirements of the surface of the foundation cushion. If there is unevenness, apply fine-grained concrete to fill the surface.
4. Prior to the installation of the stone railings, the arrangement diagrams of the meteorites, slats, columns and other members of the stone railings shall be drawn in accordance with the design drawings, and the centerline and sideline of the stone members shall be discharged at the construction site.
5, stone railings before installation, should remove the stone surface debris, rust and other impurities, if necessary, water cleaning.
6, the choice of stone components, its strength rating should not be less than MU20. The mortar of the earth rock block should be cement mortar, and its strength grade should not be lower than M10.
Second, stone railings to lay stone
1. Prior to the laying of the gangue stone, first remove the dirt and debris on the foundation cushion.
2. Pull the line to determine the center line and edge, and pop the ink line, then press the line steadily. After the mantle is stable, check the position of the mantle and columns on the mantle.
3, floor rock should be laid when the first seated pulp, that is, at the base of the first paving cement mortar, according to the line with a crowbar to the stone leveling, leveling, correcting, stable. Then use a hemp knife to crack the joints.
Third, the installation of the column
1. Pull the cable to install. Pull the side line of the column on the column seat surface, and the center line of the column will pop out on the side of the column seat. During the installation, the cross line on the column top stone should coincide with the column center line.
2. When installing the pillars, clean the trenches and the armpits of the pillars and the meteorites. First wipe a layer of cement mortar with a water-cement ratio of 0.5 gram on the armpits, with a thickness of about 10 mm. Then look at the columns. The quasi-center line is built up, and if there is a vertical deflection, the iron sheet can be used to flatten the edge of the ash seam.
3. When installing a stone column, check the verticality of the entire column at any time with a wire drop. If there is a skew, you should remove it and do not use a knocking method to correct it.
Fourth, board installation
1. Before the installation of the fences, the centerline and sidelines of the components should be popped up on the columns and the meteorites to check the elevation. After the fence line is placed, install it according to the pre-drawn bar chart.
2. Block-seat: Before installing the fence, clean up the grooves and armpits on the column and the meteorites, brush a layer of plain cement slurry with a water-cement ratio of 0.5, and then install it to ensure that the between the fence and the column is not Leave gaps.
3. Handling: When carrying the board, each rope must be subjected to force at the same time, and carefully check the force position of the stone and slowly place it. Put the picked part on the temporary support.
4, in place: railings stone structure by squatting, nest, slot in place.
5. Adjustment: When the board is installed in place, carefully check with the control line. If there is an offset, you should reset it to the correct position.
6, hooking: If the gap between the stone is larger, you can in the joints at the marble glue, marble glue color should be adjusted according to the stone color using white cement for color adjustment can achieve the best results; if the sewing is fine, should Apply grease or plaster; if there is a design, follow the design instructions. Ash joints should be leveled with the stone components and must not be hooked. Ash joints should be straightforward, tight and clean.
7. After the installation is completed, if there is unevenness in the part, the chisel can be cut into a pickaxe and the stone surface can be washed.
Fifth, other details processing
1. Construction of settling joints (expansion joints): The fences and the meteorites are to be separated according to the spacing required by the design, and the settlement joints (expansion joints) should be set at both ends. The width of the joints should be set according to the design requirements (such as design No requirement, set a settlement joint according to 50 meters (slot width 3cm).
Marble railing installation note:
Before installing the stone railings, in order to ensure that the installation process does not leak, before the construction, you should check the following points:
1 Inspection of stone railings: First, check whether the various components of the stone railings are cracked, damaged, stained, etc. If the surface cannot be seen, you can tap it with a hammer. If a sound is heard, then there is no damage. The sound of friends is somewhere hidden.
2 The texture of the stone railing should conform to the force requirements of the monolithic structure, paying particular attention to the straight orientation of the column.
3 Stone railings are a kind of safety device as a fence. Before installation, it is necessary to check the type, scope of application and force limit of the stone railings. The stone railing must have a factory-certified certificate and test report.
4 Before installing the stone railings, the surface of the stone railings should be clear of dirt, rust, etc., and should be washed with water again. Keeping the stone railing wet is beneficial to the installation work.
