Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, concretely is a frame beam reinforcing device for building engineering. BACKGROUND

[0002] In the field of building engineering, as the core stressed component in the building structure system, the frame beam bears the key role of transmitting the floor load to the vertical load-bearing components such as columns and walls. With the increase of building service life, the frame beam is prone to problems such as load capacity reduction, structure deformation and even crack propagation due to factors such as concrete carbonization, steel corrosion, design load standard improvement or unexpected disasters (such as earthquakes and impacts). These diseases not only affect the normal use function of the building, but also may cause structural safety hazards, threatening the safety of life and property. Therefore, improving the bearing capacity and durability of the frame beam through reliable reinforcement technology has become a necessary means to ensure the safety of building structure and prolong the service life of building.

[0003] Currently, the common frame beam reinforcement technology has significant limitations. For example, the steel plate reinforcement method needs to rely on high-strength structural glue to realize the collaborative stress of the steel plate and the beam body, but the glue layer is easily affected by high temperature and humid environment and fails, leading to the overall destruction of the reinforcement system. The carbon fiber cloth reinforcement technology has very high requirements for construction technology. If the base treatment is not proper or the pasting is not dense, it is easy to have hollowing and peeling phenomenon, which cannot fully play the material performance. The section reinforcement method can effectively improve the bearing capacity, but it may cause new problems such as foundation load overrun and change of original structure stress system due to the large increase of structure self-weight. In addition, the traditional technology generally has the disadvantages of long construction period, large occupation of building space, difficulty in dealing with complex structure or narrow working environment, etc. It is difficult to meet the needs of modern building rapid construction and precise reinforcement in actual engineering application. Therefore, we propose a frame beam reinforcing device for building engineering. UTILITY MODEL CONTENTS
