I. Brand Safety Inspection - The Necessity of Outdoor Facility Safety Inspection
1. Due to outdoor facilities often being located in bustling urban areas and densely populated regions, various safety issues arise, posing a threat to the safety of property on a large scale. With poor weather or during strong wind seasons, incidents of signs collapsing are not uncommon, and cases of signs injuring people have been frequently reported.
2. Large ground signs are typically made of steel structure and are usually located in bustling districts, public places, or along roadways. Therefore, under the premise of achieving the desired effect, the safety of the structure is particularly important. In recent years, accidents involving ground signs have frequently caused damage to life and property, and have led to numerous liability disputes across the country.
3. Shenzhen Zhongjiano Engineering Technology Co., Ltd. various sign plate inspection reports, highway sign inspection, roadside sign inspection, rooftop sign inspection, steel structure sign inspection. Welcome to call: Manager Yu.

II. Brand Safety Inspection - Brand Structural and Construction Measures Inspection:
1. According to relevant architectural design specifications, temporary structures (including outdoor signs) must meet a wind resistance standard equivalent to a 25-year event. Historical statistics indicate that in Hangzhou, this standard requires a sign to withstand a load of 38-40 kg per square meter, meaning it must be capable of withstanding winds of about 10 levels. When calculating the wind resistance of a specific sign, factors such as local terrain, landforms, wind direction, and velocity must be considered, as well as the shape, volume, and area of the sign. For instance, the wind resistance varies depending on whether the area is an open plain or a high-rise district, and on the different heights within the same location. For instance, stable winds can only hinder walking at speeds of 35 km/h, whereas turbulent winds can cause the same trouble at speeds as low as 16 km/h. While pedestrians can withstand strong stable winds, it's difficult to maintain balance in the face of sudden changes in wind direction and velocity, even if the wind speed is not high.
2. To measure the wind resistance of a sign, one must first know the basic wind pressure value, then multiply it by coefficients such as wind pressure height variation, landform shape, gust, and sign body shape. For instance, at a height of 10 meters in Hangzhou, the basic wind pressure is around 50 kg. Without considering other coefficients, a sign with an area of 15 square meters would withstand a wind force of 750 kg; at a height of 50 meters, the basic wind pressure is approximately 80 kg, and the sign with an area of 15 square meters would bear a wind force of 1200 kg.

One, Brand Safety Inspection Company - Due to the fact that most signs are made of steel structures and are constantly exposed to outdoor elements such as sun exposure and rain, they are prone to damage. Generally, outdoor steel structure signs require regular inspections and maintenance.

Section 2: Brand Safety Inspection Company - The basic construction of the brand has two types:
1. Balanced Gravity Design: The top load is primarily counterbalanced by the gravity of a large-volume foundation, requiring more concrete but easier construction and steel savings. Suitable for construction in soft soil conditions with ample construction sites.
2. Pile foundation: Mainly uses expanded pile foundations, suitable for construction sites with limited space. The advantage is that the foundation construction site is small, and the concrete used is only about one-third of that for gravity-based foundations, but the construction difficulty is slightly higher. To effectively control the stability of steel structures, a reasonable design scheme for steel structure stability must be adopted, focusing on the strength, rigidity, and stability of the structure to ensure safety and reduce potential threats to life.

Three, Brand Safety Inspection Company - Brand Welding Inspection (a crucial point, most brand connections are either welded or articulated):
1. Bridge Connection Node Inspection Method: Inspectors use the dye penetration method to inspect the welds at the connection of the bridge members. Inspection reveals that the rectangular steel tubes and square steel tubes of the bridge truss have insufficiently filled welds, with instances of under-welding and missed welding. The welds connecting the truss rectangular tubes to the steel columns are not dense, with slag and holes present. Similar issues are found in the welds at the connections between steel columns and in the stiffeners of the truss members. This indicates serious problems with the welding quality of the bridge.

Four, Brand Safety Inspection Company - Brand Inspection Standards:
CE148-2003 Technical Code for Steel Structures of Outdoor Facilities
G205-2001 Specification for Quality Acceptance of Steel Structure Construction
G018-2002 "Technical Code for Cold-formed Thin-Walled Steel Structural Engineering"
G661-2011 Specification for Welding of Steel Structures
Outdoor Facilities Inspection Standard DB37/T487-2004
JGJ81-2002 "Technical Code for Welding Technology of Building Steel Structures"
JGJ82-91 Design, Construction, and Acceptance Specification for Bolted Connections in Steel Structures
DG/T J08-804-2005 "Standard for Structural Inspection and Evaluation of Existing Buildings"

One, Brand Safety Inspection - China Construction Research Corporation's Brand Safety Inspection Center - Due to the nature of structure and location of outdoor facilities, high quality requirements are placed on them. However, insufficient efforts in design, manufacturing, installation, and maintenance, as well as insufficient attention to safety of outdoor facilities, lead to numerous potential hazards in the structures of most outdoor facilities.
1. Brand Safety Inspection Co. - Engineering Survey Mistake: During the design of the foundation for the on-site facilities, due to insufficient geological survey, arbitrarily determining the bearing capacity of the foundation, blindly applying adjacent site survey data, and failing to identify hidden dangers such as soft layers, hidden beaches, and voids, the designed bearing capacity of the foundation significantly differs from the actual capacity. Often, after some time of use in outdoor structures, excessive settlement and differential settlement occur at the structural foundation, leading to tilt accidents in the facilities.
2. Brand Safety Inspection Company - Inappropriate design sections of facilities were not designed by a design institution, but constructed based on experience alone. Although some have design drawings, they do not align with the actual conditions due to insufficient attention from designers, resulting in mismatches between engineering drawings and reality, inadequate structural plans, inappropriate construction measures, and simplified structural calculation diagrams that do not correspond to the actual situation.
3. Brand Safety Inspection Company - Poor Construction Quality: Most construction teams have personnel with low quality, lack understanding of design intent, and blindly carry out construction. In some cases, they even擅自 modify blueprints or cut corners for convenience, resulting in outdoor facility structures that fail to meet safety requirements.
4. Brand Safety Inspection Company - The contractor for structural use or renovation, to meet the needs of existing content, without proper calculations, expanded the area of the original outdoor facilities for renovation, causing the structure to be used over its design load for a long time, resulting in the original structure's load-bearing capacity no longer meeting safety usage requirements.

The Shenzhen Zhongjiano Research and Engineering Technology Co., Ltd. is equipped with qualifications for various structural steel parameter inspections, including weld inspection, bolt tensile pull-out testing, coating thickness measurement, deflection testing, structural steel component dimension inspection, steel component cross-section inspection, and steel component damage inspection, among others, with the necessary permits and inspection capabilities.
