How to install billboards that are not against the wall

The materials of billboards are generally made of: square tubes, angle steel, etc., which are welded. It can include three-dimensional boards, light cloth, blister, car paint, gusset boards, aluminum-plastic panels, etc. It would be better to use angle steel for such a large piece. When embedded parts should be used between the billboard steel structure and the concrete structure, friction expansion bolts are strictly prohibited for anchoring. When special embedded parts are installed unconditionally, other reliable connection measures should be taken, but they must be verified through force calculation and testing to ensure safety. For billboard steel structures attached to floors and walls, when bolts or welds are used to connect to the original house structure, the connecting bolts or welds should be calculated based on the overall overturning resistance of the structure. The calculated stress of the bolts or welds does not Should be greater than the design value of bearing capacity.

The connecting parts between billboards and walls. Wall billboards should be attached to the wall of a house or structure. It should be determined or verified that the wall of the house or structure can reliably withstand the force transmitted by the billboard, and Have necessary safety reserves. The connecting parts of wall billboards can be connected to the embedded parts in the columns or beams of the wall by welding, bolts or anchors. They can also be connected by qualified chemical anchors and planting bars. Friction-type expansion anchors are strictly prohibited. For the wall of an outdoor building, if you are considering using it for one or two years, you can use 3X3 angle steel as the main material. If you are considering using it for three to five years or even longer, use 4X4 angle steel, and add 0.4mm to the finished grid. galvanized sheet (windproof), and then install the picture, there are many auxiliary materials, such as No. 10 round steel, stainless steel edge strips, paint, rivets and welding rods, etc. This kind of steel frame must be maintained regularly after it is completed. The maintenance period depends on the degree of damage. It is usually no more than once a year. In cities with a lot of rain or even acid rain, it should not be more than half a year. The service life of the steel frame will be extended under normal maintenance. A poorly maintained steel frame may not last 5 years if larger materials are used. If you want an accurate budget, it's best to send photos, as installation difficulty may vary. We make steel frames like this all year round.

1. The dry-hanging method, also known as the air-hanging method, is an advanced construction technology currently used in wall decoration. This method uses metal pendants to hang the facing stone directly on the wall or steel frame without using mortar. The basic principle is to set the main stress-bearing points on the main structure of the building, and use metal pendants to fix the stone on the surface of the building to form a stone decorative curtain wall.
2. After carrying out the horizontal joints of the marble, install the horizontal angle steel frame. First determine the installation position of the billboard, then remove the entire stone at the fixed point and fix the billboard with angle steel welding. In order to ensure the stability of the advertising rack, angle steel with a diameter of more than 30 mm should be used to connect to the steel structure part, and when positioning, try to make the advertising rack cover the gap left after the stone is removed.
3. The installation sequence should be column hoisting first, then the billboard frame installation, then the sign surface installation, and finally the sporadic components.
4. Before installation, arrange for technicians to measure and review the foundation. The inspection content includes: whether the foundation plane is flat and free of cracks, honeycombs, exposed reinforcements, etc.; whether the transverse and longitudinal center lines of the foundation are vertical; whether the deviation of the foundation's overall dimensions does not exceed 20 mm.
5. When selecting a suitable installation location, geological conditions, component stability and greening protection should be considered. The lifting height should be appropriate to facilitate hoisting fixtures and installation operations; use wind ropes to adjust the verticality of the column to ensure safety and avoid people approaching; pass theodolite verification to ensure that the verticality of the installation is less than 10 mm.
6. During the installation process of billboards, in addition to paying attention to hoisting safety, it is also necessary to ensure firm welding and anti-corrosion treatment at the joints; during the hoisting and lifting process, the verticality of the billboard frame must be adjusted to avoid Tilt and continuously adjust to a safe position. The entire process should be directed by a dedicated person and the operation should be unified.
7. Complete the installation of the light frame and other components according to the design drawings.
