How to install zinc-steel balcony guardrail

Zinc-steel balcony guardrail refers to the balcony guardrail made of zinc alloy. Because of its high strength, high hardness, beautiful appearance and bright color, it has become the mainstream product used in residential quarters. Zinc-steel balcony guardrail has the characteristics of welding-free, convenient installation, four-layer anti-corrosion treatment and environmental protection. The installation of zinc-steel balcony guardrail is roughly divided into four steps: first, make preparations, then assemble and install the railing, and finally check the installation quality. A, the balcony guardrail safety height

Balcony guardrail is a beautification and protection facility for the outer edge of balcony, which is welded or assembled by alloy pipes. The common low windowsill is about 0.5 meters from the ground. If a 0.4-meter guardrail or fence is added near the inner wall, it will certainly meet the protection measures required by the code. If the desktop of the windowsill is too large, such as a bay window, children often stand on the windowsill and look out, and users must stand on the windowsill to open the window. At this time, the height of the guardrail attached to the window sill should reach 0.9 meters.

Secondly, the zinc-steel guardrail has the following characteristics

1, no welding assembly design, quick and simple installation.

2. Four layers of anti-corrosion treatment, the service life is more than 20 years, which can solve the problems of rust, pulverization and cracking of traditional products in a short time and avoid the cost of product maintenance and update.

3, good decoration, rich colors, to meet the individual needs of different customers for products.

4, environmental protection, no environmental pollution, solving the problem that ordinary products pollute buildings.

5. Good flexibility. The rigidity and flexibility of the base material make the guardrail products have good impact resistance.

6. The surface treated by electrostatic spraying imitation pond porcelain technology makes the guardrail products have good self-cleaning performance, and can be as clean as new after being washed by rain and sprayed by water gun.

7. Buried installation and anchor plate installation not only save your building foundation cost, but also save land resources.

8. Good weather resistance, salt spray resistance and damp heat resistance, suitable for use in different regions.

Three, zinc steel balcony guardrail installation steps and matters needing attention

Step 1: Preparation before installation of zinc-steel balcony guardrail

1. Check and prepare all installation tools before construction.

2. Check whether the installation accessories are complete by comparing the contents of the parts list one by one.

Step 2, railing assembly

1. First of all, in the process of assembling the guardrail, the surface of the guardrail should be prevented from being scratched, and the carpet or paper cushion should be paved on the construction site.

2. When the crossbar is connected with the upright post, put the upright post protective cover into the hole A of the crossbar, and tap it with a rubber hammer to fix the protective cover on the crossbar. Insert the stud from the other end to the other end into the hole A of the crossbar (the hole of the drilling stud should be in the same direction as the hole on the crossbar), and lock the anti-disassembly screw on the drilling stud. When installing the connecting block on the column, be sure to pay attention to that the connecting block is installed on the column on the side only in one direction.

Finally, lock the anti-disassembly screw on the connecting block.

3. After the face pipe is connected with the upright post, draw lines according to the drawing size to determine the position of a pass on the face pipe, fix the pass with self-tapping screws, put the face pipe into the pass, tap it with a rubber hammer, and punch 1 rivet on the side of the pass.

Step 3, install the railing.

2. Fix the face tube accurately. According to the height of the drawing, determine the position of the mounting card of the face tube, draw lines and make expansion screws, fix the face tube on the wall, and then pull nails to fix the face tube.

3. Finally, when installing the column, first pay off on the basis of the ongoing construction, determine the position of the fixed point of the column, then drill the hole with an impact drill, and then install the expansion screw. After the screw is fixed, two people need to cooperate when tightening the screw. One person holds the column vertically (with a level), and the other person cannot shake when tightening the screw.

Step 4, check the installation quality of zinc-steel balcony guardrail.

1. Confirm whether the shape, size and installation position of the railing meet the design requirements through observation, ruler inspection and entry inspection records.

2, by checking the concealed engineering inspection records, confirm whether the number, specifications, location and connection points of the fixed points of the railing column meet the design requirements.

3. Through observation, ruler inspection and hand board inspection, it is confirmed that the railing height, column spacing and installation position must meet the design requirements. Railings must be installed firmly without looseness.

4, railings, handrails installation allowable deviation and inspection methods should comply with the "advanced decoration engineering quality inspection evaluation standard".

Verticality of railing: 2mm. Messenger wire and ruler quantity inspection; Distance between railings: 2mm. Messenger wire and ruler quantity inspection; Straightness of surface pipe and cross bar: 3mm, stay and check with ruler; Height difference of railing: 2mm. Check with a ruler.
