The function of the block machine in the construction industry is introduced.

- Feb 25, 2018 -

In the construction industry, the use of the block machine is very frequent.

The block machine is mainly used for the production of various types of cement blocks, cement support and other construction products.

The cement block made by the block machine can be used as the protective layer of reinforcement, so the quality requirement of cement block is very high.

So, do you know what role the cement block plays in the construction industry?

Let me give you more details.

1. The protective layer of the external force has the anchoring force of the steel bar, and the anchorage force between the concrete and the steel reinforcement is used, and the two are closely combined to participate in the work together.

When the protective layer is too thin or missing, it reduces its anchoring force, thus reducing the function of the structure resisting axial force and bending moment.

2. The fire protection layer concrete has a certain insulation effect, and can protect the steel bar which is easy to soften in case of fire.

If the protective layer is too thin, it is easy to crack under high temperature environment, which causes the steel reinforcement to reduce the strength due to overheating, thus damaging the whole structure.

In 2003, a project in hengyang, hunan province, was caused by high temperature and high heat caused by fire.

3, easy maintenance structure durability of concrete protective layer is too thin in the infiltration of wet gas and water, too thick, easy to produce cracks, these could make the steel corrosion and inflation, so that the destruction of a concrete influence use and security of structure.

It can be seen from the calculation formula of flexural capacity from the normal section that when the thickness of the reinforcement is too thick, the effective height of the cross section will be reduced by h0, which will reduce the flexural capacity of the section.

Cement block made of cement block machine can make the concrete inner bar not affected by the outside world, the quality is better.
