What is an expansion reinforcement belt Can the expansion reinforcement belt be canceled

The expansion reinforcing belt is a technical measure to compensate for shrinkage concrete by pouring the post-pouring belt part of the structure, reducing or canceling the post-pouring belt and expansion joint, and extending the length of the continuous pouring of the component, which can be divided into three types: continuous, intermittent and post-casting.

The continuous expansion reinforcement belt refers to the simultaneous pouring of the concrete at the expansion reinforcement zone and the adjacent concrete on both sides; Intermittent expansion reinforcement belt refers to the concrete at the expansion reinforcement belt site and the adjacent concrete on one side are poured at the same time, and the other side is a construction joint; The pouring method of the post-poured expansion reinforcing belt is the same as that of the conventional post-pouring belt.

Expansion Reinforcement Belt] is also known as: Expansion Concrete Reinforcement Belt. It is an ultra-long concrete whole-pouring pouring technology that uses a grade higher than the poured concrete and is set at the largest part where the concrete shrinkage stress of the building occurs to increase the compactness of the concrete, improve the strength and crack resistance and anti-seepage performance of the continuous pouring concrete.

It is mainly used to replace the continuous pouring seamless construction technology of the post-pouring belt.

The expansion reinforcing belt is required to be arranged at the largest part of the concrete shrinkage stress, generally that is, the middle position of the length direction, a reinforcing belt is set up every 30m in the direction of the length and width of the roof, the width is 2m, the upper and lower steel bars on both sides of the belt are provided with 6mm steel wire mesh, the grid size is 35 35mm, and the two ends are respectively tied to the upper and lower steel bars, and the concrete in the belt is separated from the outside of the belt.

When the design strength of the expanded reinforced out-of-band concrete is C40, the CSA content is 10% (the same amount of cement replacement), and the design strength of the in-band concrete is C45, the CSA content is 12% (the same amount of replacement cement). The increase of 5MPa in the belt is to improve the tensile strength of the expansion and strengthen the belt and prevent the concrete from cracking in the most cracking part, and the amount of CSA in the belt is increased by 2% compared with the CSA of the concrete outside the belt, so as to improve the expansion rate of the concrete in the most cracking part, eliminate the tensile stress in the concrete in the part, and avoid cracking.

Summary. If the expansion reinforcing belt is adopted, it can be canceled or poured as soon as possible, which will basically overcome these many difficulties and bring a lot of convenience to the construction. Through the application in practical engineering, the continuous pouring seamless construction technology of replacing the post-pouring belt with the expanded concrete reinforcing belt is adopted, which not only eliminates these problems, but also increases the compactness of the concrete, and improves the strength and crack resistance and anti-seepage performance of the concrete.

At the same time, the construction period can be shortened, and the effect is more significant.

What is the difference between intumescent reinforcement tape and post-pouring tape?

1.Let's talk about the post-pouring belt first, the construction technology of the post-pouring belt is to pour concrete on both sides of the belt first, and after the concrete on both sides is poured for 40 60d, the concrete that is one level higher than the strength of both sides is used to carry out in-band pouring to reduce the method of large-volume or super-long structural concrete cracks.

2.Regarding the expansion reinforcement belt, there are three types of expansion reinforcement belts, which are continuous expansion reinforcement belts, intermittent expansion reinforcement belts and post-poured expansion reinforcement belts. Among them, when the wall structure is less than or equal to 60m, continuous pouring is adopted, the plate structure is less than or equal to 60m, and more than 60 is less than 120 and the thickness is less than the continuous type, and the rest of the cases are post-poured or intermittent.

What is the purpose of expansion reinforcement tape?

The above is my opinion on what is the difference between the expansion reinforcement belt and the post-pouring belt? What is the purpose of the expansion reinforcement belt, and what is the difference between the expansion reinforcement belt and the post-pouring belt? I have a general understanding of what the purpose of the expansion reinforcement belt is, and I hope my introduction above can help you.

Contact. The post-pouring expansion reinforcing belt is similar to the post-pouring belt, the two sides need to be pre-embedded waterstop, the two sides are poured first, and the concrete in the belt is poured after the strength is reached, so there are two construction joints.

Distinguish. First, the principle is different.

1. Expansion reinforcement belt: expansion reinforcement belt is a technical measure to compensate for shrinkage concrete by pouring compensation shrinkage concrete at the preset post-pouring belt part of the structure, reducing or canceling the slag Xiaohu, such as the blocking belt and expansion joint, and extending the length of continuous pouring of components.

2. Post-pouring belt: It is a temporary construction joint left in the corresponding position of the foundation floor, wall and beam in accordance with the requirements of the design or construction specifications in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to its own uneven shrinkage or uneven settlement in the construction of the building.

Second, the role is different.

1. Expansion and strengthening belt: underground Shenshen buildings: such as subways, underground parking lots, underground warehouses, tunnels, mines, civil air defense projects, foundation pits, etc.; pools, swimming pools, water towers, storage tanks, large containers, granaries, oil tanks, warehouses in caves, etc.; High-strength highway pavement, bridge concrete surface, culvert, etc.

Anchor joints of prefabricated components, frame structure joints, pipe joints, grouting materials of post-tensioned prefabricated components, backfilling of post-pouring joints, and magma grouting materials; Cement products: self-stressed, prestressed and steel sleeve prestressed concrete pipes, floor slabs, columns, beams and columns, waterproof roof panels, etc.; Non-shrinkage pouring between the anchor screws of mechanical equipment, the base and the concrete foundation.

2. Post-pouring belt: solve the settlement difference and reduce the temperature shrinkage.

Third, the functions are different.

1. Expansion and reinforcement belt: realize the self-waterproofing of the structure: cancel the external waterproof measures and improve the economic benefits 2 3;Cancel the super-long cast-in-situ structure after pouring belt:

The 60m length of the underground project is not provided with a post-pouring belt, and if it exceeds 60m, the post-pouring belt is replaced by a ZY expansion reinforcement belt to reduce costs and shorten the construction period.

Temperature difference crack control of large-volume concrete: using ZY products, relaxing the temperature control index, no longer using traditional construction methods such as cooling aggregates and burying cooling pipes in concrete, saving construction costs.

2. Post-pouring belt: When the pouring time of the post-pouring belt is low, cement or cement mixed with trace aluminum powder can be used to pour concrete, and its strength grade should be one level higher than the strength of the component, so as to prevent cracks between the new and old concrete and the formation of weak parts. The location of the post-pouring belt should also consider the different consumption factors of the template and other measures.

The difference and connection between the expansion reinforcement belt and the post-pouring belt are:

1. The post-pouring expansion reinforcing belt is similar to the post-pouring belt, the waterstop needs to be embedded on both sides, the two sides are poured first, and the concrete in the belt is poured after the strength is reached, so there are two construction joints;

2. The intermittent reinforcing rotten belt is to pour the concrete on one side first, and then pour the concrete in the belt and the concrete on the other side together after the strength is reached. Therefore, the water-stopping steel plate needs to be embedded on the first pouring side, and there is a construction joint after the construction is completed;

3. The continuous pouring method is to pour the concrete inside and outside the belt together, and the water-stopping steel plate is not buried on both sides, and there is no construction joint after the pouring is completed.

Introduction to post-pouring tape:

The construction technology of the post-pouring belt is to pour concrete first on the side of the belt with two bases, and after the concrete on both sides is poured for 40 60 days, the concrete with a higher strength than the two sides is used to pour in the belt to reduce the cracks of large-volume or super-long structural concrete. The specific pouring time should also be determined according to the requirements of the architectural design.

Introduction to Intumescent Reinforcement Bands:

There are three types of expansion reinforcement belts, which are continuous expansion reinforcement belts, intermittent expansion reinforcement belts and post-poured expansion reinforcement belts.

Among them, when the wall structure is small, Zhengyu is equal to 60m, and continuous pouring is adopted.

The plate structure is less than or equal to 60m, and when it is greater than 60 and less than 120 and the thickness is less than 120, the continuous type is used, and the rest of the cases are post-poured or intermittent.
