Roof billboard steel structure design drawing

The production of outdoor billboards should be in compliance with the overall layout of the building and the architectural design requirements of the design of the building facade. The construction drawings should be closely consistent with the design. Coordination; Twenty years is the design life of large high-post outdoor billboards, and other types of outdoor billboards are designed for ten years. The load for setting up outdoor billboards should be specified in 1. The basic wind pre ssure should be implemented at 0.45kN/m2, and the height coefficient, wind vibration coefficient, shape coefficient, etc. should be considered; for earthquake-prone areas, the combination of earthquake effects and other loads should also be considered. The steel structure used in outdoor billboards should comply with the relevant provisions of GB50017 and "Technical Specifications for Steel Structures of Outdoor Billboards" 3, and the torsional strength check calculation of the steel structure connecting parts should be considered.
Second: The basic structure design of outdoor floor-standing billboards should meet the following requirements:
① Outdoor floor-standing billboards should be based on the soil conditions and structural foundation requirements of the construction site. And the ground foundation strength should be calculated reasonably. If necessary, the stability of the ground foundation against sliding should be calculated. The area of ​​the bottom of the foundation away from the foundation shall not exceed 1/4 of the area of ​​the foundation;
②Based on a rigid foundation, the usual eccentric load should comply with the "Building Foundation Design Code" GB50007 for the design of outdoor floor-standing billboards;< br/>③When the foundation is lower than the groundwater level, the buoyancy effect of groundwater on the foundation and casing should be considered, and the groundwater should not corrode the foundation, and corresponding anti-corrosion treatments should be carried out;
④When When the soft soil layer of the foundation layer is relatively thick, the upper load is large and concentrated, and the shallow foundation cannot meet the requirements for the bearing capacity and deformation of the outdoor floor-standing billboard steel structure foundation. A caisson or pile foundation can be used. The pile foundation uses pre fabricated reinforced concrete piles, cast-in-place concrete piles or steel pipe piles. This type of pile foundation should be determined after compre hensive analysis based on geological conditions, structure type, load size, construction conditions and the environment of the construction site. The calculation of the pile foundation is carried out in accordance with the "Design Code for Building Foundation Foundation" standard of GB50007.
Third: The design of the bracket base of outdoor rooftop billboards should meet the following requirements:
① Outdoor rooftop billboards should not be connected with friction expansion bolts. It is necessary to use good chemical anchors, planting bars and self-wall anchors, which must have pre cise technical parameters and quality assurance systems;
② The layout of the bracket base of the outdoor rooftop billboard should match the layout of the roof column network Properly, it should be able to directly bear the load-bearing pre ssure, tension and shear force of the billboard structure;
③The base of the outdoor roof billboard bracket can be welded and connected with bolts, anchor bolts, top beams and embedded parts in the column, and can be effective and reliable Spre ad the load from the base of the advertising signage support to the bearing capacity of the substructure;
④The embedded depth of concrete bolts or anchor bolts should reach 30 to 40D (d is the diameter of the bolt); the anchor bolts Installation should meet the technical requirements of the product used. When the embedding depth is not enough, welding with beam and column steel bars should be used, and at the same time, sufficient thickness of the concrete protective layer must be ensured.
Fourth: The lightning protection and grounding design of outdoor advertising Xiangzao signs should meet the following requirements:
① Outdoor billboards should take corresponding lightning protection measures according to the environment they are in, including pre venting lightning and lightning attack.
② Outdoor billboard lightning protection facilities (including access equipment, shunts, grounding equipment, overvoltage protection equipment and other connecting conductors) should be designed according to the lightning protection environment and the environment in which they are located. The lightning protection design must pre vent direct lightning and lightning attack measures;
③ When installing outdoor billboards on the roof or exterior walls of a building, the lightning protection facilities can be consistent with the design of the building's lightning protection grounding system. Combination;
④ When installed on the roof of a multi-story residential building, outdoor billboards should be welded to a steel structure frame, metal plate and residential building lightning protection system, and ensure that its grounding resistance is not greater than 4Ω, and vice versa. An additional lightning protection grounding system is required;
⑤The grounding system of outdoor billboards should form an equipotential connection;
⑥The steel structure frame, metal plates, etc. of outdoor billboards can be used as connecting air terminal equipment. Line lightning protection equipment, but must be connected with multi-point welding connections to the down conductors of floor and wall lightning protection systems;
⑦In independent outdoor billboards, in addition to being installed inside and outside protected lightning protection belts and lightning protection nets, the steel frame Metal plates and steel columns should be effectively grounded. Grounding wires can be shared or laid separately; building lightning protection grounding and other lightning protection grounding equipment, including various types of metal pipes, should be connected to the same lightning protection grounding facility;

Billboards are the most widely used information transmission medium, with sustained and stable effects, and are widely used in various fields. Among them, billboards are mainly divided into light boxes, luminous characters, signs, advertising towers, etc. Among them, the most common ones we see are various light boxes and luminous characters, which are also the main types produced by various businesses.

1. There are two main types of illuminated characters on store billboards: luminous and non-luminous.

1. The most common luminous characters are acrylic luminous characters, stainless steel edge luminous characters, blister luminous characters, etc.

The price is: 350 yuan/square meter

2. Non-luminous characters generally include acrylic, iron characters, stainless steel characters, copper characters, and Chevron characters.

The price is: 150 yuan/square meter.

Door bottom board materials are generally plastic boards, tempered glass, door gussets, anti-corrosion wood and metal paint boards. The shop signboard is composed of two parts: the door base and the door characters.

The price of the door base plate is: 200-400 yuan/square meter

Many businesses have already completed the production of the base plate for billboard production when they are looking for a billboard production company. This charge is generally calculated based on the title material you choose plus the installation fee. If the door sign base material has not been installed or nothing has been done, it will generally consist of three parts:

①Billboard design cost

②Sign base material cost and Cost of making door letters

③Worker installation costs

2. Door light box

Door light box includes: blister light box, fabric light box, stainless steel hollow Light boxes, etc., among which the most commonly used are fabric light boxes and blister light boxes.

1. The cost structure of the fabric light box consists of four parts: steel structure spray painting screen LED light source manual installation cost. The general cost is 500-850 yuan/square meter.

2. The blister light box consists of four parts: steel structure blister panel and LED light source manual installation cost. The general cost is 750-950 yuan/square meter.

3. The stainless steel hollow light box is composed of five parts: steel structure, metal paint, acrylic LED light source and manual installation cost. The general cost is 1,000 yuan/square meter.
