Abstract
The present invention adopts prefabricated thin muscle net sheet to replace the bar reinforcement of commonly using, and need reinforce the position at building, carry out metope earlier and handle, by the thin muscle net sheet of seismic hardening requirements placement, apply prestressing force after, the anchoring of usefulness anchor pin, powder high-grade cement mortar.With method of the present invention existing multi-layer brick house of not setting up defences is carried out seismic hardening, add the important of solid only for commonly using the solid that adds of reinforcement means, about 20% of weight, and it is low to reinforce cost, easy construction does not influence the profile of original building, and economic and social benefit is remarkable.
Description
The present invention relates to a kind of anti-seismic reinforcing method by use of prestressed fine reinforcing fabrics and thin cement sand beds.This method is specially adapted to existing multi-layer brick house of not setting up defences is carried out seismic hardening.
The casualties that earthquake causes mainly is that house collapse causes.Existing house of not setting up defences is carried out seismic hardening, is very effective measures of earthquake disaster mitigation.Therefore, the earthquake-resistant building reinforcement means that research is best with less fund input, reaches earthquake disaster mitigation effectively, assures the safety for life and property of the people, and has been the ten minutes urgent task.
At present, the Shockproof reinforcing method of domestic employing, though there is certain pattern to follow, and have the relevant seismic hardening atlas can reference.But these reinforcement means are still among exploring, and have many problems to remain reform and perfect.Subject matter is that fund input is many, and it is big to add solid volume, and construction is complicated, influences former housing appearance etc.
Purpose of the present invention provides a kind of anti-seismic reinforcing method by use of prestressed fine reinforcing fabrics and thin cement sand beds.This method is with cold-drawn or hot rolling fine steel rib; be prefabricated into fine steel rib net sheet; be installed on the position of the collar tie beam that needs reinforcement and constructional column; with an amount of prestressing force of special-purpose machinery stretch-draw; be anchored on the body of wall with the anchor pin then, whitewash the skim cement mortar at last, protection fine steel rib net sheet non-corrosive; and make it effective adhesive is arranged with body of wall, reach the purpose of seismic hardening.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is that waist hoop of the present invention is reinforced schematic diagram.
Fig. 2 is that attached wall corner post of the present invention is reinforced schematic diagram.
Fig. 3 is the reinforcing schematic diagram of attached wall buttress post of the present invention.
Fig. 4 is that interior wall pull bar of the present invention is reinforced schematic diagram.
Quality situation and local earthquake intensity according to the house are carried out reinforcing design, by drawing, at the position that needs reinforcement, carry out metope and handle.Referring to accompanying drawing, on body of wall 1, bisque on the former metope or pointing with cement mortar are chiseled out, clean with scour without sediment motion, to guarantee adding solid and original wall body is well-bonded.Select to have the fine steel rib of the quality certification by drawing, carrying out straightening handles, according to real size, be prefabricated into fine steel rib net sheet 2, be installed on the position of reinforcing, carry out prestressed stretch-draw with special tensioner, after applying appropriate pre _ stress, anchor pin 3 with some is anchored at fine steel rib net sheet 2 on the body of wall 1, whitewashes with high-grade cement mortar 4 at last, and compacting troweling and maintenance.
Adopt the present invention that the multi-layer brick house of not setting up defences is carried out seismic hardening, theoretically, brick masonry housing is made up of fragile material, and characteristics are that rigidity is big, flexible poor.Reinforce multi-layer brick house with prefabricated fine steel rib net sheet, can improve the fragility in house, increase ductility, the non-deformability in house is improved greatly, strengthened the shock resistance in house on the whole.
With method of the present invention existing multi-layer brick house of not setting up defences is carried out seismic hardening, the weight that adds solid only adds about 20% of solid weight for reinforcement means just commonly used now.The cost of reinforcing also greatly reduces, and easy construction, and particularly thin type is reinforced the attractive in appearance of the outline body that do not influence former house, and economic and social benefit is very remarkable.
Claims (2)
1, prestressed thin reinforced net sheet thin type cement mortar Shockproof reinforcing method is characterized in that each position that need reinforce at building carries out metope earlier and handle, and places fine steel rib net sheet, with the anchor pin it is anchored on the body of wall after applying prestressing force, the powder high-grade cement mortar again.
2, by the described seismic hardening method of claim 1, it is characterized in that being prefabricated into the net sheet with the fine steel rib of cold-drawn or hot rolling.
