specific Embodiment approach

[0035] Such as Figure 1 ~ Figure 2 Shown, the specific embodiment of the present invention is as follows:

[0036] A reinforced jacket-type layered structure, including the original structure longitudinal wall 1, the original structure horizontal wall and the original structure floor, and also includes the newly added jacket layer frame, long steel plate 5, wall outer steel backing plate 6, fixed steel backing plate 7. Sealing plate 8, rib plate 9, and anchoring steel backing plate 11; the newly added outer layer frame is a reinforced concrete structure, and the concrete strength grade is C30, including the inner column 3 of the outer layer frame, the outer column 2 of the outer layer frame and the space between them Set the coat frame beam 4.

[0037] Between the vertical wall 1 of the original structure and the inner column 3 of the jacket frame, steel backing plates 6 outside the wall are provided corresponding to the upper and lower positions of the floor of the original...

Abstract

The invention relates to an enhanced cover-type story-adding structure and a hardening method thereof and belongs to the seismic hardening field. A newly-added cover-type story-adding framework is adopted and comprises a cover framework inner column and a cover framework outer column, as well as a cover framework bream arranged therebetween; strip-shaped steel plates are arranged on the upper surface and the lower surface of the cover framework beam; the newly-added cover-type story-adding framework and an original structure are connected through adding the strip-shaped steel plates and end anchoring, so that the novel and new structures are connected more closely and the structural stability is enhanced. Meanwhile, the part of the original structure transverse wall, not meeting the shock-resistant requirement, is hardened through steel pull rods at firstly, and anchor plates at the two ends are connected with the newly-added cover-type story-adding framework in an anchoring manner. By adopting the structure and the method which are provided by the invention, the hardening effect is enhanced, the two structural systems are adopted for bearing together, so that the anti-seismic property is improved on the whole.

Description

technical field [0001] The invention relates to a reinforced sheath-type layered structure and a reinforcement method thereof, belonging to the field of seismic reinforcement. Background technique [0002] With the improvement of anti-seismic codes and standards, the anti-seismic index and performance of some old and existing buildings can no longer meet the requirements; and the rapid development of social economy makes the land use in big cities very tight. Especially in a metropolis like Beijing, the pressure on land supply in the central urban area is very prominent. In order to alleviate this contradiction, the government has carried out renovations of existing buildings such as old urban areas or old communities, and can carry out additional floors and reinforcements on the basis of suitable existing buildings. Many problems need to be faced in the actual project, and some reasonable renovation measures have not been proposed in the prior art. How to provide a structu...
