Embodiment Construction

[0027] Combine below Figure 1 to Figure 4 , the present invention is further described:

[0028] like figure 1 As shown, the reinforced walls include the outer longitudinal wall 2 of the old masonry building, the inner transverse wall 3 of the old masonry building, the inner longitudinal wall 4 of the old masonry building and the outer transverse wall 5 of the old masonry building. The above-mentioned transverse walls and longitudinal walls are connected in a staggered manner. Unbonded prestressed tendons 1 are vertically arranged on both sides of any transverse wall or vertical wall, and the unbonded prestressed tendons 1 apply a certain prestress to the wall, so that the seismic capacity of the reinforced wall is greatly improved.

[0029] like figure 2 As shown in the figure, a vertical unbonded prestressed anti-seismic strengthening structure of a masonry building, in which unbonded prestressed tendons 1 are vertically arranged on both sides of the reinforced wall 11,...

Abstract

The invention relates to a vertical un-bonded prestressed anti-seismic strengthening structure of a masonry building. The structure is characterized in that un-bonded prestressed ribs are vertically arranged on each of two sides of a strengthened wall, a coping beam or a wall top force transfer shim block is arranged on the top of the strengthened wall, and the tension ends of the un-bonded prestressed ribs are anchored on the coping beam or the wall top force transfer shim block; a foundation force transfer shim block is arranged on the foundation part of the strengthened wall, and the fixed ends of the un-bonded prestressed ribs are anchored on the foundation force transfer shim block; and by applying a pre-stressing force, the anti-seismic capability of the strengthened wall is greatly improved. The vertical un-bonded prestressed anti-seismic strengthening structure of the masonry building can effectively improve the anti-seismic bearing capacity of the masonry wall and enhance the integrity and the energy dissipation capability of the masonry structure, is beneficial to deformation recovery after seism, is easy and convenient to construct, low in influence and low in manufacturing cost, and belongs to a novel anti-seismic strengthening technology of masonry structures which are worthy of vigorous promotion.

Description

technical field [0001] The invention relates to a building anti-seismic reinforcement technology, in particular to a vertical unbonded prestressed anti-seismic reinforcement structure of a masonry building. Background technique [0002] At present, the seismic fortification capacity of many old houses in China does not meet the requirements. On the one hand, this is due to the fact that there are still no seismic fortifications in old buildings or that the seismic capacity does not meet the requirements of seismic identification in accordance with early seismic code design; on the other hand, previous earthquake damage surveys have also found that some buildings lack formal Design or fail to carry out seismic fortification according to the design standards at that time, there are various quality problems in design or construction, collapse and damage occurred under the action of a large earthquake exceeding the fortification intensity in the area, and failed to realize the s...
