Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with specific embodiments.

[0024] Composite wallboard (commercially available thin-walled steel-foam concrete composite wallboard 15 and embedded parts (second embedded part 2, third embedded part 3) are made in the factory, composite wallboard 15 is arranged at the end of original structural column 14, The width on each side shall be 2m, and the longitudinal spacing shall not exceed 24m.

[0025] figure 1 The standard floor and the vertical section of the top floor nodes are reinforced by the present invention for a single-span frame structure classroom. The upper end of the composite wall panel 15 is connected to the original structural beam 13, and the lower end is connected to the original structural floor 12. On site, the anchor bars of the first rear anchor 4 and the second rear anchor 5 are implanted into the original structure by means of planting bars, and the composite wall panel 15 is p...

Abstract

The invention discloses a single-span frame structure classroom combined wall board type quick reinforcing method. A combined wall board (15) is arranged at the end of an original structural column (14), the width of each side is 2m, the longitudinal distance does not exceed 24m, an embedded part is arranged in the combined wall board, an original structure is provided with a rear anchoring part, and reliable connection between the combined wall board and the original structure is achieved through effective connection between the embedded part and the rear anchoring part. A reinforcing construction period is shortened greatly, the interference to the original structure is small, structural redundancy rate is increased, and the reinforcing amount of the original structure is decreased. After the reinforcement is performed by means of the combined wall board type quick reinforcing method, the burden of original frame beams and columns is relieved, and large-area reinforcement to the beams and the columns is avoided.

Description

technical field [0001] The invention relates to a reinforcement structure and design method, in particular to a method for quickly reinforcing a classroom with a frame structure by using a new composite wall panel, which belongs to the field of reinforcement technology. Background technique [0002] Due to the lack of multiple anti-seismic defense lines, the single-span frame structure has low structural redundancy. The "Seismic Appraisal Standard" (GB50023-2009) has clear restrictions on the application of single-span frames to key fortification buildings in schools. At the same time, the national primary and secondary school building safety projects are in full swing. Single-span frame with cantilevered corridors is a common structural form of teaching buildings. Therefore, a large number of single-span frame structure classrooms are in urgent need of seismic reinforcement. [0003] Among the current reinforcement technologies, the most commonly used reinforcement methods ...
