Description
Technical field
The present invention relates to a kind of method that adopts steel part to carry out seismic hardening to existing masonry structure.
Background technology
In 512 Wenchuan violent earthquakes and 414 cajaput earthquakes, the villages and small towns masonry house that a large amount of common people oneself build collapses, and the people's lives and property has been caused very big destruction.This class masonry house is mostly without rational design and construction, much even constructional column and collar tie beam be not set, lacks effective the connection between body of wall and body of wall, floor and the body of wall, and the globality in house and space rigidity are very poor, have big potential safety hazard.For example under the severe earthquake action in length and breadth the wall junction easily destroy, the body of wall short time, inside and outside the sudden strain of a muscle collapsed, and caused structural entity to lose bearing capacity.
In order to ensure villages and small towns resident's the security of the lives and property, need carry out seismic hardening to a large amount of existing masonry structure that has built up.Adopting at present more is to paste FRP method and steel mesh reinforcement mortar surface layer method etc., but the most cost of these methods is higher or construct loaded down with trivial detailsly, and the common people are difficult for accepting.For this reason, be necessary to propose a kind of cheap and can effectively improve the reinforcement means of seismic performance of building.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings, provide a kind of method of existing masonry structure being carried out seismic hardening.
Technical scheme of the present invention is as follows:

Above-mentionedly a kind ofly adopt steel part to carry out in the method for seismic hardening to masonry structure, described horizontal steel part is arranged near the basic end face for the treatment of the outer facade of reinforcing masonry structure, near the roof system and near the superstructure.
Above-mentionedly a kind ofly adopt steel part to carry out in the method for seismic hardening to masonry structure, the vertical steel part of vertical steel part in described edge and middle part with treat directly to contact between the reinforcing masonry structure surface or adopt cement mortar material to bond together.
Above-mentionedly a kind ofly adopt steel part to carry out in the method for seismic hardening to masonry structure, the side of the vertical steel part in edge is along the vertical pertusate connector of affixed reservation at interval, the pertusate connector of the also affixed reservation in two ends of horizontal steel part of while, the vertical steel part in edge is connected by described connector with horizontal steel part, and the width of described connector is less than the width of horizontal steel part; Be provided with stiffening rib between horizontal steel part and the connector, also be provided with stiffening rib between vertical steel part in edge and the connector; Adopt screw bolt and nut that horizontal steel part is strained by the connector that is fixed in respectively on vertical steel part in edge and the horizontal steel part during installation.
Above-mentionedly a kind ofly adopt steel part to carry out in the method for seismic hardening to masonry structure, it is fixing with the adjacent vertical steel part welding of vertical steel part in edge and middle part that horizontal steel part is tightened up the back.
Above-mentionedly a kind ofly adopt steel part to carry out in the method for seismic hardening to masonry structure, during to vertical steel part in edge and the welding of horizontal steel part, the earlier direct butt welding in vertical steel part in edge and the horizontal steel part position except that connector or elder generation's employing lapping plate are covered on the vertical steel part of horizontal steel part and edge and carry out overlap welding, then connector is cut off, again butt welding or overlap welding are carried out in the position of being cut off connector.
Above-mentionedly a kind ofly adopt steel part to carry out in the method for seismic hardening to masonry structure, the vertical steel part in described middle part is arranged at intersection of wall in length and breadth and the allowable ratio of height to sectional thickness of masonry wall or column for the treatment of the outer facade of reinforcing masonry structure and does not satisfy " Code for design of masonry strucres " (GB5003-2001) ratio of height to thickness requirement place.
Compared with prior art, the present invention has following advantage: this method is cheap, and easy construction is easy to large tracts of land and promotes, and can effectively improve the globality of structure, obviously improves the anti-seismic performance of structure.The present invention utilizes the globality and the space rigidity of steel part enhancing structure, because horizontal steel part wherein also can apply certain horizontal pretightning force, so can postpone the generation of allowable ratio of height to sectional thickness of masonry wall or column diagonal crack under the geological process.The shear-carrying capacity of body of wall, extreme displacement raising all are significantly improved.
Description of drawings
Fig. 1 is the layout schematic diagram of the present invention vertical steel part in edge, the vertical steel part in middle part and the horizontal steel part that adopt steel part existing masonry structure is reinforced.
Fig. 2 is the schematic diagram of the present invention at structure corner connector pattern one.
Fig. 3 is the schematic diagram of the present invention at structure corner connector pattern two.
Specific implementation method
Below in conjunction with accompanying drawing concrete enforcement of the present invention is described further, but enforcement of the present invention and protection domain are not limited thereto.
Referring to Fig. 1, certain treats that the reinforcing masonry structure plane is about the rectangle of 12m * 7m, totally three layers, and bottom floor height 3.5m, two, three high layer by layer 3m.The twice cross wall is set, and structure adopts the horizontal wall load-bearing system, seismic fortification intensity 7 degree.
