Materials needed for structural transformation and reinforcement in Qingdao


Qingdao structural transformationReinforcementmaterials needed

Carbon fiber reinforced

(1) Thickness: 0.111mm (200g), 0.167mm (300g)

(2) Width: can be cut at will, generally 100mm, 150mm, 200mm, 250mm, 300mm

Advantages: high tensile strength, corrosion resistance, convenient construction, light materials, no additional load

Disadvantages: Compressive strength is 0, no stiffness contribution, no fire resistance, poor durability

Steel plate reinforcement

Thickness: The thickness of steel is generally 3~6mm, and the maximum thickness of Q235 does not exceed 10mm

Width: 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, etc.

Advantages: high tensile/compressive strength, high bearing capacity (20%~40%), simple construction, without changing the shape of the component and the use space

Disadvantages: not fire-resistant, easy to corrode

High-strength grouting material

Advantages: good self-flowing, fast hardening, early strength, high strength, no shrinkage and micro-expansion; non-toxic, harmless, non-aging, no pollution to water quality and surrounding environment, good self-sealing and rust resistance

Disadvantages: the cost is much higher than ordinary concrete

Epoxy mortar, epoxy resin

Features: high bonding strength with metals and non-metals; stability; corrosion resistance; hydrophobicity; electrical insulation

Uses: often used for building waterproofing, plugging, crack repair

Qingdao structural transformationspecialty:

1. The general process is to conduct structural appraisal first, and then carry out reinforcement design and construction according to the appraisal report

2, Reinforcement should minimize disturbance and damage to the original structure, such as sticking carbon fiber and sticking steel reinforcement

3, Before reinforcement, the owner shall provide the original building, structural drawings, and geological data of the house; The relevant house inspection and appraisal report. The more information the better

4, Reinforcement should try to choose advanced and reliable technology, and then consider factors such as economic rationality.

6, Generally, it is necessary to unload the original structure before the construction of the reinforcement project to minimize the influence of the secondary force.
