Embodiment approach

[0022] figure 2 , the second embodiment of the present invention is: the upper end of the composite wall panel 11 is connected to the ring beam 9 of the original structure, and the lower end is connected to the floor slab of the original structure. During the installation of the bottom floor, the first connectors 6 at 8 places on the original structural floor have been fixed, the second rear anchors 5 are implanted into the original structural ring beam 9, the surface of the anchor plate is flush with the surface of the original structural ring beam 9, and the second connector 7 passes through The bolt connection is fixed with the upper rear embedded part, and the protruding edge of one side of the groove is welded with the second rear anchor piece 5 . Accurately locate the installation position of the composite wall panel 11 to ensure that the upper end of the third embedded part 3 at the upper end of the composite wall panel 11 is in close contact with the first connecting ...

Abstract

The invention discloses a method for fast strengthening a classroom in a masonry structure by using a combined wall plate. The combined wall plate is internally provided with an embedded part, an original structure is provided with a rear anchoring part, and the reliable connection of the combined wall plate and the original structure is realized through the effective connection of the embedded part and the rear anchoring part. According to the invention, the strengthening construction period is greatly shortened; the original structure is less interfered; a foundation is unnecessary to excavate in the construction process, and the exterior facade of a building is not influenced; the anti-seismic capability of the original structure is enhanced; good comprehensive benefit is achieved; the combined wall plate is light in weight, can not increase the burden of the foundation after being strengthened or consume a template in the installing process and is unnecessary to brush on a surface layer after being completely installed, the total strengthening cost is lower, and the heat preservation and insulation performance of an original building enclosure is enhanced by together combining an anti-seismic strengthening goal of an existing building and indoor environment improvement.

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 masonry structure by using a composite wall panel, and belongs to the field of reinforcement technology. Background technique [0002] With the development of school security projects across the country, it was found that a large number of teaching buildings could not meet the requirements of key fortifications during the earthquake resistance investigation, and there were great potential safety hazards in earthquake resistance. The masonry structure accounts for the largest proportion of the existing teaching building, and its seismic performance is poor, so seismic reinforcement is urgently needed. [0003] In the current reinforcement technology, the reinforcement method of reinforced concrete slab wall or reinforced mesh mortar surface is the most commonly used for masonry walls; however, both methods require bi...
