As we all know, reinforced concrete structure is commonly used in today's world of architectural forms. However, due to the extension of the service life or other causes of reinforced concrete building components of the bearing capacity is not enough, the strength of its components, stiffness or cracking, cracking, etc. are not uncommon. Especially in our country, since the founding of many buildings have been to the maintenance and reinforcement of the peak; to ensure the normal and safe use of buildings, the construction industry is often encountered problems. In addition, due to changes in use of the building to transform, reinforcement works also increased. The rapid development of science and technology, especially the new progress of petrochemicals, for this year's building reinforcement provides a new type of reinforcement construction technology and new chemical building materials - building structural adhesives.
 In the construction, the application of structural adhesive to connect all kinds of components, reinforcement or repair, compared to the traditional connection reinforcement method has many outstanding advantages:
 1, the use of synthetic resin adhesive to connect, reinforcement components, riveting than the average, welding force uniform, the material will not produce stress concentration (such as welding thermal stress, etc.), so that more resistant to fatigue, especially better To ensure the integrity of components and improve crack resistance, and the integrity of the relationship between the basic extent of the load-bearing capacity and stability.
 2, structural adhesives can be different nature of the material firmly linked to the diversity of building materials today, but also traditional methods can not match the advantages.
 3, the use of adhesive construction, the process is simple, can greatly shorten the construction period, often 1-2 days or less can be used in short, especially in the reinforcement of various types of components, especially so that some traditional methods can not be reinforced components To repair and reinforcement; for some important military projects, transport facilities is particularly important. And its anti-aging performance, can meet the various requirements; in the construction can also improve efficiency, reduce costs, energy conservation.
 Building structural adhesives to today, has become a special type of special plastic, and its varieties have dozens of many, according to use can be divided into: structural adhesive for reinforcement; anchoring, anchor construction adhesive; repair with structural adhesive ; Site construction with structural adhesive. In addition can also be composed, construction status classification.
 The adhesive of building structure combines the results of advanced technology such as chemistry, mechanics, material, structure, photoelectricity and so on. It is applied to the reinforcement of steel structure of building structure, anchor bar anchorage and on-site pouring construction, showing its outstanding merit and importance. Chengdu Zhengguang Technology Co., Ltd. and other domestic companies after years of unremitting efforts, have successfully mastered their technology, and applied to the actual construction, to solve some of the traditional methods of strengthening the traditional difficult to solve the problem, creating a huge Economic and social benefits. I believe that building materials such as adhesives and technology will have a bright future.
