specific Embodiment approach

[0035] Such as Figure 1 ~ Figure 2 As shown, the specific implementation of the present invention is as follows:

[0036] A reinforced jacket type added layer 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, the long steel plate 5, the outer steel pad 6 and the fixed steel pad 7. Sealing plate 8, rib 9 and anchoring steel backing plate 11; the newly-added outer layer frame is reinforced concrete structure, the concrete strength grade is C30, including outer column 3 of outer frame, outer column 2 of outer frame and between the two Set of jacket frame beam 4.

[0037] Between the original structure longitudinal wall 1 and the outer frame inner column 3 corresponding to the original structure floor slab, the outer wall steel backing plate 6 is respectively provided at the lower position, and the fixed steel backing plate 7 is respectively pr...

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 jacket type added layer structure and a reinforcement method thereof, belonging to the field of seismic reinforcement. Background technique [0002] With the improvement of seismic codes and standards, the seismic indicators and performance of some old existing buildings have not met the requirements; and the rapid development of society and economy has made large cities very tight. Especially in a metropolis like Beijing, the land supply pressure in its central urban area is very prominent. In order to alleviate this contradiction, the government is carrying out the renovation of existing buildings such as old urban areas or old communities, and can add floors and reinforce them on the basis of suitable existing buildings. There are many problems that need to be faced in actual engineering, and the prior art does not propose some reasonable transformation measures. How to provide a structure with good seismic performa...
