What is chemical reinforcement planting

Chemical reinforcement planting, (referred to as planting reinforcement, also known as seed reinforcement), is a kind of post-anchoring connection technology widely used in China's engineering community, which is the use of high-strength chemical adhesives.

The steel bar, screw, etc. and the concrete are bonded and interlocked, so as to achieve the gripping force of the connected parts, so as to achieve the embedded effect. After construction, it produces high bearing capacity, which is not easy to shift and pull out, and can be used where various steel bars and screws need to take root. It has good sealing performance and does not need to do any waterproofing treatment.

Because it is fixed by chemical bonding, it will not only not cause expansion damage to the substrate, but also is more suitable for parts with small margins and spacing. Moreover, it has a reinforcing effect on the structure, which can increase the bending, bending and shear stress between the concrete.

The performance of construction, simple and fast, safe and in line with environmental protection requirements, is a reinforced concrete structure in construction projects.

One of the most effective ways to change, add, and harden.

Chemical reinforcement planting is a widely used post-anchoring connection technology in the engineering community, which uses high-strength chemical adhesives to make steel bars, screws, etc. and concrete through bonding and locking key action, so as to achieve the holding force of the connected parts, so as to achieve the effect of embedding. Chemical reinforcement technology is aimed at the simple and effective connection and anchoring technology of concrete structures, which can be implanted with ordinary steel bars or bolted anchor bars. It has been widely used in the reinforcement and renovation of existing buildings, such as the remediation of leakage of buried steel bars or steel bars deviating from the design position in construction, the reinforcement of components to increase cross-section reinforcement, the expansion of superstructures, the extension of jacking beams and columns, the addition of floor columns in houses and the planting reinforcement of shear walls in high-rise buildings.

Planting reinforcement is a kind of construction term, which is essentially planting reinforcement. On the construction site, in order to strengthen the building, the engineering designer either continued to build, or drilled holes in the original building, inserted steel bars, and then used special glue to fill the joints, so that the steel bars were anchored in it, so that the steel bars and the original building were integrated, which is the planting bar.

On the construction site, reinforcement planting is a specific practice of masonry reinforcement. Engineers will choose to reserve steel bars or choose to plant bars, both of which are to ensure the stability of the primary and secondary structures of the project. Masonry reinforcement refers to the two projects with poor integrity, connecting the two with steel bars, and the masonry wall of the workers is imitated when the columns are poured.

Although the functions of masonry reinforcement and reinforcement are similar, there are still many differences between them. First of all, it is not the same in the realization, the former is to set up some reinforcement frames in the ash joints of the masonry, if it is a brick-concrete structure, it is necessary to build the wall first and then pour the structural column. Reinforcement can be laid at any time, and finally poured concrete.

As for the reinforcement planting, because it is generally carried out under the condition that the engineering frame or column and concrete wall have been poured. As a result, if the reinforcement of the wall wants to be connected to it, it can only be connected to the front and placed in the column or in the wall until the end, and then the hole in the column is drilled, and the steel bar that needs to be implanted is anchored in it with structural adhesive.

Reinforcement is used in many places. For example, when the window sill is pressed to the top, in order to prevent or alleviate the cracks in the wall of the bottom layer of the house, usually through the method of increasing the stiffness of the foundation ring beam, about 3 welded steel mesh sheets can also be used in the ash joint of the wall under the window sill at the bottom of the bottom, and at the same time, it is required to penetrate into the wall between the windows on both sides shall not be less than 600 mm. This nuclear resistance is a kind of use of planting bars.

建瀚 (zhíjīn) refers to a construction technique that uses steel bars or other materials to reinforce and strengthen concrete structures. This technology can improve the tensile performance and ulnar cavity bearing capacity of concrete structures to prevent cracking or failure of the structure when stressed.

In the reinforcement planting technology, the construction personnel will embed the steel bars in the concrete pouring process and form a good bond with the concrete. These rebars are typically in strips and are embedded in specific locations of the structure in accordance with design specifications and requirements.

The purpose of planting reinforcement is to jointly bear the force of the structure and improve the strength and stability of the structure through the connection between the steel bar and the concrete. This technique is widely used in the construction of buildings, bridges, tunnels, and other concrete structures.

It is worth mentioning that the reinforcement planting project needs to strictly follow the relevant construction specifications and process requirements to ensure the quality and effect of the reinforcement planting. When carrying out the reinforcement planting project, it is recommended to seek the guidance and supervision of a construction engineer or related experts to ensure the safety and reliability of the project. <>
