Beijing Haiping guardrail guardrail company is engaged in the production, installation, sales and service of professional fence company, especially for the installation of a wealth of practical experience, specifically the following: First, a wall fence, wall fence usually civil engineering has been before installation lower base-forming brick or concrete pouring pound delivered, the fence can be mechanical expansion bolt, chemical, etc. will post Screw in the steel liner plate fixed to the lower base of the central portion of a straight line uniform. 2. The lower base of the wall has not yet formed, it is recommended to increase the length of the column steel liner directly embedded in the wall, until the curing period to the formal construction of the wall; or pre-embedded parts laying in the wall plane after the steel column lined with embedded welding welding way, which is characterized by two ways more secure than the bolt connection, but must pay attention to the horizontal straight line preset. 3, column spacing steel liner designed to be consistent with the size of the pre-assembled semi-finished products to ensure energy connected thereto. 4, in a straight line from the whole paragraph to pull the lower two parallel lines for installation adjustment reference. Guardrail installation to ensure flatness after the completion of the upper and lower ends. 5, the horizontal bar of Shanghai, firm to the steel liner installed in the factory are connected, each anchorage reinforcing parts have also been installed, when the construction site only need to cross the fence lining the column connecting fixed. Second, road isolation barrier 1, road isolation barrier at the factory according to the order requested series assembly, product only part of each column of the steel liner is inserted after the arrival of the construction site stable base, by the use of the line extension with the department for layout. 2. After completing the basic layout of the use of special bolts each guardrail properly jointed. 3, to improve wind cypress columns, anti-malicious mobile, stable base and the ground should be provided with expansion bolt for fixing the ground. 4, then the user requirements in the fence to the top fixed installation reflector. 5, the mobile base can be cast iron spike or expansion screws symmetrical locked. Third, the stair balcony rails a reference to the "wall fence" column fixation method column stationary steel lined with the ground connection. 2, the upper and lower ends of each column to pull up and down the parallel lines measuring the angle with a protractor. 3, according to the required angle matching connector, according to the required angle oblique cutting assembly guardrail. 4, fence post installation with reference to the practice of isolation barrier contacts; Guo Jingli Tel: 13220196153 010-56180445
