I. Brand Safety Inspection - China Construction Research Corporation's Brand Safety Inspection Center - There are numerous safety hazards in outdoor facilities due to their structure and location, which places high demands on their quality. However, insufficient efforts in design, manufacturing, installation, and maintenance, coupled with inadequate attention to safety in outdoor facilities, have resulted in many outdoor facilities having numerous potential hazards.
1. Brand Safety Inspection Company - Engineering Survey Error: During the foundation design of the on-site facilities, due to the lack of thorough geological survey, arbitrary determination of soil bearing capacity, and blind application of neighboring site survey data without identifying potential hazards such as soft layers, hidden dunes, and voids, the designed soil bearing capacity significantly differs from the actual capacity. This often leads to excessive settlement and differential settlement in the structural foundation after a period of use outdoors, causing the facility to tilt.
2. Brand Safety Inspection Company - Inappropriate design for certain facilities was not carried out by a design institution, and construction was based solely on experience. Although some facilities had design drawings, the lack of attention from designers led to discrepancies between the engineering drawings and the actual situation. Issues included suboptimal structural designs, inappropriate construction measures, and structural calculation diagrams not aligning with the actual conditions.
3. Brand Safety Inspection Company - Poor Construction Quality: Most construction teams have subpar personnel with a lack of understanding of design intentions, leading to blind construction. In some cases, for the sake of convenience in construction, they even擅自 alter blueprints or cut corners, resulting in outdoor facility structures that fail to meet safety requirements.
4. Brand Safety Inspection Company - The commercial for structural usage or improper reconstruction areas, in order to meet the current content requirements, expanded the area of the original outdoor facilities for modification without proper calculation, causing the structure to be used beyond its designed load capacity over a long period, resulting in the original structure's load-bearing capacity not meeting the safety usage requirements.

Safety inspections are required for outdoor signs.
1. Connection Quality and Performance Testing

Label connection quality and performance testing includes:

Welded connections, screw钉 connections, bolt connections, and bolted joints.

The quality of full penetration welds for grades 1 and 2, as well as steel sections where no design requirements are specified for strong weld joints, can be inspected using ultrasonic testing methods.

2 Brand Inclination Detection

Measure the offset value at the top of the H-beam column relative to the bottom using a total station, in accordance with the relevant regulations for the point projection method in deformation measurements.

3 Brand Power Characteristics

Perform power tests on the sign, obtaining vibration frequency, amplitude, etc., and analyze the dynamic characteristics between the sign and surrounding buildings.

4 Structural Load Test for Brand

For large complex steel structural systems, in-situ non-destructive load testing can be conducted directly to verify structural performance.

When there is doubt about the load-bearing capacity of the structure or components, prototype or full-scale model load tests can be conducted. The tests should be entrusted to an institution with sufficient equipment capabilities. A detailed test plan should be formulated prior to the test, including the test objectives, selection or fabrication of specimens, loading devices, placement of measurement points and testing instruments, loading steps, and the evaluation method of test results.

The stress of steel structural members can be measured according to actual conditions by using resistance strain gauges or other effective methods.

Brand Non-Destructive Testing Specific Products: Brand safety inspections, ground signs, billboard signs, single-pole signs, wall signs, rooftop sign inspections, highway sign inspections, road sign inspections, toll booth sign inspections, etc. Brand Non-Destructive Testing Standards: CE148-2003 "Technical Code for Steel Structures of Outdoor Facilities," G205-2001 "Code for Quality Acceptance of Construction Quality of Steel Structures," G018-2002 "Technical Code for Cold-Formed Thin-Walled Steel Structures," G661-2011 "Code for Welding of Steel Structures," DB37/T487-2004 "Inspection Code for Outdoor Facilities," JGJ81-2002 "Technical Code for Welding of Building Steel Structures," JGJ82-91 "Design, Construction, and Acceptance Code for Bolted Connections of Steel Structures," DG/T J08-804-2005 "Standard for Structural Inspection and Evaluation of Existing Buildings." Inspection Basis: Design Requirements. Brand Non-Destructive Testing is one of the main forms of outdoor testing in China. With the economic development of China's non-destructive testing and the continuous improvement of urban construction and planning, outdoor sign non-destructive testing has also received increasing attention as a scenic feature in the city. As a carrier of outdoor facilities, their unique placement plays a positive role in corporate product quality, social image, and cultural connotation promotion. Due to the nature of the structure and location of outdoor facilities, higher quality requirements are placed on them, and there are frequent incidents of damage and collapse of outdoor facilities in harsh environments, causing injuries to surrounding personnel and property losses. Types of Brand Non-Destructive Testing Included: Wall signs, ground signs, rooftop signs. Content of Brand Non-Destructive Testing: 1. Horizontal and strength indicators of the non-destructive testing base. 2. Overall structural assembly and welding quality of the non-destructive testing. 3.

One, Brand Safety Inspection - Brands are mostly steel structures. As early as one year ago, in July 2003, the Construction Engineering Standardization Association issued the "Technical Code for Steel Structures of Outdoor Facilities" (CE148:2003), which provides detailed regulations and explanations for the installation and maintenance of outdoor facilities.

II. Billboard Safety Inspection - There are two main reasons for outdoor billboards becoming unstable: one is the instability of the billboard foundation, and the other is the aging and cracking of the rigid structure.
1. The supporting base for outdoor signs is commonly referred to as the foundation, which can be soil or rock for freestanding signs, and is further divided into artificial and natural foundations. Building signs and wall signs use the roof and wall structures as their foundation. For outdoor signs, the setup of the foundation is crucial, as it directly impacts the normal operation of the sign.
2. Common causes of foundation engineering accidents include:
Inadequate foundation bearing capacity leads to foundation instability.
The subsoil is excessively soft, leading to foundation tilting after long-term negative loading.
Changes in the surrounding geological environment can cause the soil mass of the foundation to expand or contract.
Bracket loosening or damage on wall signs; uneven settlement of building signs caused by external factors (including strong winds, rough construction, etc.).

Section 3: Brand Safety Inspection - Purpose of Inspection
To enhance safety awareness, promote the philosophy of safe development, continuously improve the safety consciousness of personnel and production, and strive to create a more favorable environment for outdoor facility safety and foster the safe development of outdoor activities. Adhere to the people-oriented philosophy and the concept of safe development, maintain a policy that prioritizes safety and prevention, strengthen the responsibility of safety management, enhance the level of safety management, effectively prevent and control various outdoor safety production accidents, and create a harmonious social environment with a pleasant urban landscape.

Section 4: Brand Safety Inspection - Key Points

V. Brand Safety Inspection - Inspection Content
Establishment and implementation of the system:
① It is a daily safety self-inspection system. The individual is responsible for the safety of all outdoor equipment for their lifetime, with clear inspection duties, scheduled inspection cycles, and on-site checks integrated into daily operations.原则上, these checks should be conducted at least twice a month, and a timely safety self-inspection record should be maintained for each check.
② Establish a safety inspection system for outdoor facilities. Conduct an annual safety inspection based on the size of the outdoor facility signage, wind strength, and technical specifications and quality standards for design, manufacturing, and installation. Especially before or after forecasted severe wind and other disaster weather, conduct specialized safety inspections to ensure absolute safety.
③ Establish a safety inspection record for outdoor facilities. All large outdoor facilities with a single board area of 10㎡ or more, which have been approved for installation, must be registered in detail based on their years of outdoor use, location, position, wind resistance, manufacturer, and design drawings. A file must be created for future inspection.
