Zhejiang C50 plum blossom concrete cement Longqiao cushion block factory

  Plum blossom shaped concrete cushion block is named because its shape is similar to plum blossom
There are grooves on the front and rear planes and four sides of cement mortar cushion block
One cushion block can be used in four specifications (3
5mm, 4mm and 4
5mm), and there is a binding wire perforation in the center
It is mainly used for bridges and other high-quality national key fair faced concrete projects
The product models are: 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 70mm and 90mm
The strength can reach: C25, C30, C35, C40, C50 and C60
It is used in the construction of high-speed railway, subway, tunnel, Ningbo Taizhou Wenzhou expressway, bridge, airport, wharf, civil construction and many other projects
After continuous development, the company now directly owns Zhejiang Longqiao cushion block factory, Guangdong Longqiao cushion block factory, Guizhou Longqiao cushion block factory, Fujian Longqiao cushion block factory, Hubei Longqiao cushion block factory, Sichuan Longqiao cushion block factory and Yunnan Longqiao cushion block factory
The company's direct Longqiao cushion block factory is still expanding and can be shipped all over the country
Our factory specializes in the production of various types of concrete cushion blocks, bearing platform cushion blocks, column cushion blocks, C50 cushion blocks, C40 cushion blocks, cast-in-situ beam cushion blocks, plum shaped cushion blocks, multi-purpose cushion blocks, high-strength concrete cushion blocks, square cushion blocks, perforated cushion blocks and Beam Yard cushion blocks, which are applied to the construction of Zhejiang high-speed railway, Wenzhou subway, tunnel, Coastal Expressway, bridge, airport, wharf, civil construction and other projects
Concrete cushion block, also known as reinforcement protective layer cushion block, is placed under the beam in reinforced concrete structure to expand the bearing area
It is a common method to solve local bearing
The thickness of reinforced concrete cover is related to the bearing capacity, durability, fire protection and other properties of the structure
The protective layer in the concrete for maintaining structural durability is too thin, which is easy to infiltrate humid gas and water, and too thick is easy to produce cracks, which may rust and expand the reinforcement, damage the concrete and affect the use and structural safety
Under the action of external force, the protective layer has anchoring force to the reinforcement
The anchoring force between concrete and reinforcement is used
The two are closely combined and participate in the work together
When the protective layer is too thin or missing, its anchoring force is reduced, which reduces the role of the structure against axial force and bending moment
Therefore, in the current quality acceptance work, the control of protective layer thickness has been paid more and more attention
The new specification stipulates that physical inspection shall be carried out in the acceptance process
