One, Brand Safety Inspection - China Construction Research Corporation's Brand Safety Inspection Center - Due to the nature of outdoor facility structures and locations, high requirements are placed on their inherent quality. However, due to insufficient efforts in design, manufacturing, installation, and maintenance stages, as well as insufficient attention to safety by outdoor facilities, many outdoor facilities have numerous potential safety hazards.
1. Brand Safety Inspection Co. - Engineering Survey Error: During the foundation design of the on-site facility, 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 banks, and voids, the designed soil bearing capacity significantly differs from the actual capacity. This often results in excessive settlement and differential settlement of the structural foundation after a period of use, causing the facility to tilt.
2. Brand Safety Inspection Company - Inappropriate design for certain facilities, which 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 modify blueprints or cut corners for convenience, resulting in outdoor facility structures that fail to meet safety requirements.
4. Brand Safety Inspection Company - Due to the need to meet existing content requirements, the company for structural use or renovation improperly expanded the area of the original outdoor facilities without calculation, causing the structure to be used beyond the design load for an extended period, resulting in the original structure's load-bearing capacity not meeting safety usage requirements.

Welded joints, rivet joints, bolted connections, and bolted joints, etc.

Quality of full penetration welds for Grade 1 and 2 seams, and for steel sections with no design requirements for welding, as well as for strong weld joints, can be inspected using ultrasonic testing methods.

2 Brand Inclination Detection

Utilize a total station to measure the offset value at the top of the H-beam column relative to the base, in accordance with the relevant regulations of the point-setting method in deformation measurement.

3 Brand Power Characteristics

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

4 Structural Load Test for Brand X

For large and complex steel structural systems, on-site non-destructive load testing can be conducted to directly inspect structural performance.

If there are doubts 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, arrangement of measurement points and testing instruments, loading steps, and the evaluation method for test results.

The stress of steel structural rods can be measured by selecting a resistance strain gauge or other effective methods based on actual conditions.

One, Brand Safety Inspection - Brands are mostly made of 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. Sign Safety Inspection - The reasons for outdoor signs becoming dual-sided are: one is the instability of the sign foundation, and the other is the aging and cracking of the rigid structure.
1. The support structure for outdoor signs is commonly referred to as the foundation. Ground-mounted signs are supported by soil or rock foundations, which are further categorized into artificial and natural foundations; while building signs and wall signs rely on rooftop and wall structures as their foundations. The placement of the foundation is crucial for outdoor signs, directly impacting their proper use.
2. Common causes of basic engineering accidents include:
Insufficient soil bearing capacity leads to soil instability.
The soil is excessively soft, and long-term negative pressure causes the foundation to tilt.
Changes in the surrounding geological environment can lead to expansion or contraction deformation of the foundation soil.
Brackets for wall signs are loose or damaged; uneven settlement of building signs caused by external factors (including strong winds, rough construction, etc.).

III. Brand Safety Inspection - Purpose of Inspection
With the aim of enhancing safety awareness, we promote the concept of safe development, continuously improving the safety and production consciousness of individuals, and striving to create a more conducive environment for outdoor facility safety and the advancement of safe outdoor development.

V. Brand Safety Inspection - Inspection Items
Establishment and implementation of the system:
It is a daily safety self-inspection system. The person responsible for the safety of the outdoor facilities is assigned permanently, with clear inspection responsibilities and scheduled inspection cycles. The inspections are conducted at appropriate times in conjunction with regular duties, with a minimum of two inspections per month. Each inspection must be promptly documented in a safety self-inspection record.
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 and after forecasted severe wind and other disaster weather, conduct special 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, including the years of outdoor use, location, position, wind resistance, manufacturer, and design drawings, and establish a file for future inspection.
