Main components: truss structure and painting.

Auxiliary components: auxiliary lighting (to make up for the lack of light source of the field background board); Ground protection for installation and demolition (used to protect site facilities and background plate materials from damage); Counterweight (to ensure the stability of the background plate); Black velvet (shielded truss frame structure); Rubber silent trolley (used for transporting building materials), cable ties or wires (used for fixing the display screen); Match the special fastening screws.

Construction tools and accessories: matched electric wrench, matched open-ended wrench, diagonal pliers, transparent tape and double-sided adhesive tape.

Advantages of truss background plate:

1 The construction speed is fast and the waste is small.

2.Truss is a standard module specification, which can undertake various background boards with a multiple of 10CM, and can be disassembled and used for many times, with low cost;

3. The picture is wide, without splicing, and the picture is well displayed;

4. Environmentally-friendly ink painting, with small smell on site, can be used immediately.

Disadvantages of truss background plate:

The picture quality of 1 is not clear enough compared with the photo screen;

Although it is an environmentally friendly ink painting, it still has a small amount of smell;

Because of the material, the picture is soft and can't bear the load, so it can only be displayed.

Distinction of display effect of truss backboard;

Mainly manifested in the selection of materials and painting accuracy of the picture.

Common cloth (black background cloth), cloth width (3m and 5m specifications), printing accuracy (720 points) and printing ink (environmental protection ink).

Advantages: the black background cloth has a matte picture, 720-point fine spray, good picture quality, small reflection coefficient of photos, opaque black shading layer on the back of the picture, and moderate price.

Scope of application: the theme backboard of various conference activities.

Other fabrics 1:

(02A outer glossy fabric), the fabric width is 3m, the printing accuracy is 360 points, and printing ink (domestic environmental protection ink) is used.

Advantages: the surface of 02A outer light cloth is bright, and the painted picture is shiny. With 360-point painting, the picture quality is better and the price is cheaper.

Disadvantages: the picture is easy to reflect light, the fabric of the picture has certain light transmittance, and the light behind the background plate is strong, which will expose the truss support frame behind it.

Scope of application: backboard of various conference activities with low requirements for on-site effect.

Other fabrics 2:

(Black-based knife scraping cloth), cloth width (5m specification), printing accuracy (UV 1440), printing ink (imported environmental protection ink).

Advantages: The screen of scraping cloth with black background is exquisite, and the UV 1440 point spraying is fine, with good color and small reflection coefficient, and a black shading layer on the back of the screen is opaque.

Disadvantages: the picture cost is relatively high, the cloth surface is relatively thick, and it is not easy to stretch.

Scope of application: backboard of various conference activities that require high on-site effect.

The display effect of the background board is closely related to the screen creative design in the early stage, as well as the screen material selection and professional construction in the later stage.

Truss floor is widely used in many cities. Truss floor has been applied to large-scale projects and image projects, which has gradually changed the situation of concrete planning and masonry planning in domestic construction industry, so there is a higher demand for relevant personnel of truss floor engineering.

The selection of truss floor engineering scheme is very important. The planning of truss floor should adapt to four major processes: planning (conceptual planning) is the key to truss floor planning, and what kind of planning is adopted has great influence on the interests of the project. Secondly, the component planning, what kind of component planning, the stress distribution of each stress point should be strictly accounted for. Thirdly, the section shape, which not only makes the planning film accept the weight, but also requires the section shape to have an artistic sense in people's investigation. Later, the miniaturization of node structure made the planning part cost-effective, and the space occupied could not be too large.
