Description
Technical field
The present invention relates to a kind of masonry structure building wall reinforcement device, particularly relate to a kind of device preventing unstability outside body of wall face from causing masonry structure building earthquake to collapse, be a kind of device preventing built masonry structure building earthquake from collapsing, belong to construction work protection against and mitigation of earthquake disasters field.
Background technology
Masonry structure building was once extensively adopted by industry and civilian construction, because the lower and technical requirements of cost is relatively not high, so be present in the city and country of China in a large number.The Ministry of Construction of China has issued related specifications to instruct design and the construction of masonry structure building, and the latest specification version is: " Code for design of masonry strucres " (GB50003-2011).All previous earthquake in recent years shows: the masonry structure building in accordance with Specification Design and construction has good shock resistance.
But still there is considerable masonry house, owing to building the age comparatively early, or not in accordance with Specification Design and construction, all there is structure defect---as lacked collar tie beam, constructional column, masonry mortar strength deficiency etc.If this kind of house meets with earthquake, body of wall is very easily badly shaken.
Masonry structure building mainly relies on body of wall load-bearing.According to all previous earthquake Field Research experience: the destruction of body of wall in face generally can cause metope to occur diagonal crack or forficiform bidirectional oblique crack, but body of wall is unlikely and collapses, and also can not be fallen by the floor of wall support and upper strata body of wall.The main cause causing masonry structure building to collapse is that masonry wall is in the direction unstability perpendicular to metope, the namely distortion of body of wall outside face is excessive, cause masonry wall to collapse to the direction perpendicular to metope, directly cause original floor by its supporting and upper strata body of wall to fall, cause house collapse.
So, for preventing masonry structure building earthquake from collapsing, the distortion of masonry structure building body of wall outside face will be limited by technological means.
Conventionally, the general following methods that adopts carrys out reinforcing masonry structure house wall:
1, cement mortar adds thick wall body.Specific practice is: smear certain thickness cement sand bed in the employing of masonry structure building wall surface and body of wall is thickeied.If cement sand bed is too thick, in order to avoid it comes off, take first to smear one deck cement sand bed, re-lay one deck steel mesh reinforcement, finally smear the method for one deck cement sand bed again.The method improves the shear resistant capacity in its plane by thickening masonry wall, but along with the flat in-plane stiffness of body of wall increases, quality strengthens, when there is earthquake, the geological process power that this body of wall bears is also corresponding to be increased, when there is earthquake, the breakage that this body of wall occurs may can't obviously improve.
2, paste concrete slab and add thick wall body.Specific practice is: paste certain thickness concrete slab on masonry structure building wall surface.The same with the method that employing cement mortar adds thick wall body, the method improves shear resistant capacity in its plane by thickening masonry wall, but increases along with the flat in-plane stiffness of body of wall, and quality strengthens, when there is earthquake, the breakage that this body of wall occurs may can't obviously improve.And because the concrete slab reinforced is thicker, deadweight is comparatively large, brings burden, may also need to reinforce basis after causing reinforcing to original base.
3, FRP method is pasted.FRP full name is glass fiber reinforced composite plastics, is also glass fiber reinforced plastic.Existing CFRP, GFRP, AFRP, BFRP etc. are the high performance materials formed after being mixed according to a certain percentage by fibrous material and matrix material (resin).Adopt the method for pasting FRP reinforcing masonry structure house to be first in surface of wall brushing one deck adhesive glue, then paste FRP.Because FRP price is higher, and this reinforcement means requires relatively strict to construction quality, thus with regard to economy and convenience degree undesirable.In addition, it is also main helpful to supporting capacity in wall plane to paste the method for FRP, not obvious for the raising of bearing capacity outside body of wall face.
Above three kinds of methods are all be conceived to strengthen masonry structure building body of wall shear-carrying capacity planar, and very little at out-of-plane reinforcement effect to body of wall.And all previous earthquake calamity Field Research display: destroy in wall plane and body of wall may be caused to cut up, occur forficiform cross fracture, but can not therefore collapse.So above three kinds of reinforcement means to collapse limited efficiency for preventing masonry structure building earthquake.
4, ring beam and construction column is set up.Specific practice is: near basic adjacent top surface, roof system and near superstructure, is close to masonry structure building body of wall and sets up collar tie beam, and on the corner, longitudinal cross wall intersection and the body of wall place that do not meet the requirement of current specifications ratio of height to thickness set up vertical constructional column.The collar tie beam set up and constructional column and masonry structure building body of wall are linked together by the cementitious materials such as anchor bar or cement mortar.
The parcel that the object of this reinforcing mode is to pass through set up ring beam and construction column improves the globality of masonry structure building, so first have the requirement of sectional dimension and rigidity to collar tie beam, constructional column, if collar tie beam and constructional column is more weak just cannot wale body of wall.This requirement makes newly-increased collar tie beam, constructional column obviously protrudes from metope, if outstanding outside house, then very large to the appearance effects of original masonry structure, if outstanding in house, then affects the use in room.
Secondly, newly-increased ring beam and construction column needs with the connection of body of wall very appropriate, otherwise body of wall and ring beam and construction column are out of shape separately when earthquake, cannot play the effect of ring beam and construction column.The difficulty of construction that this requirement brings is comparatively large, needs at newly-increased collar tie beam, arranges a lot of anchor devices between constructional column and body of wall.
3rd, the spacing of newly-increased collar tie beam and constructional column is comparatively large, if the mortar quality that masonry structure adopts is not high,---this problem is ubiquity in a lot of countryside housing and old historical building---this method is for degree of safety poor effect outside raising body of wall face.
Chinese invention patent 2010102191151 discloses a kind of method of existing masonry structure employing steel part being carried out to seismic hardening, the method is treating that the corner of reinforcing masonry structure utilizes angle steel as edge vertical steel parts, masonry structure alien invasion vertically adopts steel plate as middle part vertical steel parts, masonry structure alien invasion horizontally adopts steel plate as horizontal steel part; The edge vertical steel parts that horizontal steel part follows steel part horizontal in this adjacent are connected, and the middle part vertical steel parts that horizontal steel part also follows steel part horizontal in this stacked are connected.But the reinforcement principle of the method is also set up steel ring beam and steel construction post, main purpose increases the anti-seismic performance of body of wall in face.Because the spacing of steel part is comparatively large, and the bending stiffness of steel part is all less, therefore not remarkable to the effect of contraction of body of wall outside face.

3modified epoxy.Only in outer setting apparatus of the present invention of this masonry structure building.
First at elbow place, both sides, gate, window both sides arrange vertical steel pipe 2, the spacing between two vertical steel pipes is no more than 3m, and vertical steel pipe 2 is connected with roof panel 7, floor plate 8, grade beam 9 by anchor bar 4.
According to existing " Code for design of masonry strucres " (GB50003-2001), the ratio of height to thickness limit value of body of wall 6 is 4320mm, is less than This floor high.So only near roof panel 7, floor plate 8, grade beam 9, arrange horizontal steel tube 3 above window upper and lower, gate, the two ends of horizontal steel tube 3 are welded with vertical steel pipe 2.Horizontal steel tube 3 near roof panel 7, floor plate 8, grade beam 9 is also connected with roof panel 7, floor plate 8, grade beam 9 by anchor bar 4, also welds with vertical steel pipe 2 simultaneously.Now masonry structure building metope 6 is divided into some rectangular areas by vertical steel pipe 2 and horizontal steel tube 3, to get the raw materials ready gauze wire cloth 1 by the size of these rectangular areas.
Coat structure glue 5 on the surface of masonry structure building metope 6, gauze wire cloth 1 is close to masonry wall 6 and lays, four limits of gauze wire cloth 1 are connected with the vertical steel pipe 2 of its periphery, horizontal steel tube 3 by welding.
In order to protect apparatus of the present invention of installation, adopt paint brushing gauze wire cloth 1, vertical steel pipe 2 and horizontal steel tube 3, finally in surface smear one deck cement mortar of gauze wire cloth 1.
After adopting apparatus of the present invention to reinforce, house is when meeting with the geological process of fortification intensity, and masonry structure building metope 6 meeting is along himself plane foreign side to swinging back and forth, but the amplitude swung is limited by apparatus of the present invention.Because roof panel 7, floor plate 8, grade beam 9 are very little to the distortion that masonry structure building metope 6 is outer, so the vertical steel pipe 2 be connected with them by anchor bar 4, horizontal steel tube 3 are also very little to the outer distortion of masonry structure building metope 6.
Apparatus of the present invention are only arranged at the one side of masonry structure building metope 6, and when masonry structure building metope 6 is out of shape to gauze wire cloth 1, gauze wire cloth 1 tensioning, makes the deflection of masonry structure building metope 6 be no more than 50mm.When gauze wire cloth 1 is out of shape masonry structure building metope 6 dorsad, the deflection that gauze wire cloth 1 limits masonry structure building metope 6 by structure glue 5 is no more than 50mm.
Principle for seismic design of the present invention is different from Chinese invention patent 2010102191151.Vertical steel pipe, horizontal steel tube are connected by the anchor bar roof panel larger with rigidity in masonry structure building, floor plate, grade beam, elbow, longitudinal cross wall intersection by the present invention, utilize vertical steel pipe and horizontal steel tube as the border bearing of gauze wire cloth, gauze wire cloth is integral with wall connecting further by structure glue, by the rigidity of gauze wire cloth outside wall plane, the deflection of restriction body of wall outside face.And the main purpose of Chinese invention patent 2010102191151 still substitutes concrete ring beam and construction column, improve body of wall anti-seismic performance planar, because vertical and horizontal steel plate is less in out-of-plane rigidity, and the spacing of vertical and horizontal steel plate is larger, therefore be difficult to the deflection of restriction body of wall outside face, be also just difficult to stop body of wall to collapse outside the face under earthquake calamity.Adopt apparatus of the present invention reinforcing masonry structure house; effectively protect the safety of house under geological process; and add thick wall body with existing cement mortar, paste concrete slab add thick wall body, paste FRP, set up the methods such as ring beam and construction column compared with; apparatus of the present invention consume material is less; construction technology is simpler; cost is less, affects less on outward appearance and use, can spread.
