Three major factors that schools must follow when purchasing double beds

The purchase of double beds in schools needs to take into account safety, practicality, durability and space optimization. Any carelessness may cause safety hazards or management problems. This article sorts out the key points from the three aspects of safety, functionality and durability to help schools make scientific selections for how to choose a suitable double bed for school.

How to choose a suitable double bed for school:

1. Safety:

Structural stability: the core parameters that must be met first: static load of the bed ≥2000N (upper bunk) +1500N (guardrail), guardrail height ≥300mm, gap ≤75mm (anti-fall clamp), step depth ≥80mm, step rod diameter ≥20mm (anti-slip design).

Material safety: the steel thickness of metal parts must be ≥1.2mm, and wooden parts must meet the following requirements: formaldehyde emission ≤0.124mg/m³ (E1 grade standard), solid wood moisture content 8%-12% (anti-cracking and deformation).

Protective design: the R angle of the bed corner is ≥5mm to prevent students from being injured due to accidental bumps. An anti-slip baffle (height ≥50mm) is set on the edge of the upper bunk to prevent students from falling from the upper bunk. The angle between the ladder and the bed is 75°±5°, which is convenient for students to get on and off the bed.

2. Functionality:

Space optimization plan: adopt a combined structure: the bed, desk and cabinet are integrated, saving 30% of space. Adopt a telescopic design: the lower bunk can be folded into a study area.

Storage function upgrade: the drawer under the bed can be equipped with a self-locking function, the side pendant can bear a load of ≥15kg, meeting the needs of students hanging schoolbags, etc., and the depth of the bedside shelf is ≤200mm to prevent students from colliding.

3. Durability and maintenance:

Test damage resistance: test impact resistance: use an appropriate amount of weight for high impact to observe whether there is structural deformation or cracking. Corrosion resistance test: place it in a salt spray environment for 48 hours to observe whether the surface corrosion area is <5%. Moisture resistance test: Place it in a humid environment for 30 days to ensure that the wood expansion rate is ≤0.5%.

Easy-to-maintain design: whether coating technology is used, whether replaceable design is adopted for vulnerable areas such as ladders and guardrails, whether the height of the bed from the ground is appropriate, and whether it meets the cleaning conditions.

School double bed procurement needs to establish a three-dimensional evaluation system of "safety-function-durability". It is recommended to give priority to products that pass the GB/T 3328-2016 "Furniture Mechanical Properties Test" standard. For large-scale procurement, suppliers can be required to provide BIM space simulation solutions to predict actual use problems. Regularly organize student satisfaction surveys and bed safety inspections to build a solid campus safety line!
