Embodiment Construction
[0021] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.
[0022] Such as Figure 1 to Figure 4 As shown, a concrete beam reinforcement structure according to the present invention includes a beam 1, an elastic member 3 and a support plate 6, and a column 2 is provided at both ends of the beam 1, and a part installation groove is opened on the column 2 , the elastic member 3 is installed in the part installation groove, the front and rear sides of the crossbeam 1 are provided with brackets 4, the bottom of the bracket 4 is connected with the elastic member 3, and the support plate 6 is connected to the elastic member 3 through several pull plates 5 respectively. The brackets 4 on the front and rear sides of the beam 1 are connected, and the support plate 6 is located on the lower side of the beam 1 .
[0023] The center line of the elastic member 3 is perpendicular to the bottom surface o...

The invention discloses a concrete beam strengthening structure, and belongs to the technical field of building beam connection. The concrete beam strengthening structure includes a beam, elastic members and support plates, the two ends of the beam are provided with columns, the columns are provided with part mounting grooves, the elastic members are arranged in the part mounting grooves, supportsare arranged on the front and rear sides of the beam, the bottoms of the supports are connected with the elastic members, the support plates are connected to the supports on the front and rear sidesof the beam through a plurality of pull plates, and the support plates are located on the lower side of the beam. When a floor slab transmits vibration, heavy loads or even overloads to the beam, andprimary unloading or damping work is completed through an arc-shaped plate; meanwhile, the arc-shaped plate transmits the loads or vibration to springs through the supports, and secondary unloading orreduction is performed through the springs; in addition, the columns provide supporting force to the middle of the beam through the springs, the supports, the arc-shaped plate and the support plates,the beam is prevented from being suddenly broken, and the concrete beam strengthening structure has the advantages that the construction period is short, the construction cost is low, and all components are not prone to being damaged.
Description
technical field [0001] The invention relates to a reinforced concrete beam structure, which belongs to the technical field of building beam connection. Background technique [0002] With the continuous development of construction technology, buildings have higher and higher requirements for space. In engineering, building structures often need to be reinforced due to changes in use functions, structural performance degradation, natural disasters or human factors. At present, reinforcement methods for reinforced concrete beams include enlarging the cross-section of the beam, reinforcing by pasting fiber-reinforced plastics, and replacing concrete. In the case of forced vibration, the beam suddenly breaks due to insufficient ductility. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a reinforced concrete beam structure. [0004] The present invention is achieved through the following technical solutions: ...
