Abstract
The invention relates to an earthquake-resistant building block connector, which is an annular or plate-shaped connector used between building blocks, wherein the outer surface of the connector and the adjacent part of the building block are provided with tooth-shaped grooves, and the connector is embedded in the mortar joint part of a masonry and penetrates through the mortar joint to form firm connection with the adjacent building block so as to improve the earthquake resistance of the masonry. When the masonry mortar with high strength and high plastic deformation is adopted, the masonry has double functions of shock absorption and shock resistance.
Description
The present invention relates in building building block group is built, play the concrete prefabricated ring-type connector of pin key effect and the local corresponding change of building block.
With building block substitute for clay masonry walls, joint soil is energy-conservation, meets the direction of national materials for wall reform.In the existing various masonry, the little building block of concrete hollow is most widely used, this manual promptly with the little building block of concrete hollow for for example with explanation.Tangible technology economy advantage has been compared in the little building block of concrete hollow with loam brick, but the mortar joint shear strength of its masonry only is about half of same cross-sectional loam brick, thereby has limited to shear the application of the how high-rise masonry structure building of the little fragment of brick of shape concrete hollow earthquake, wide maximum in the above earthquake protection of 7 degree district.
The way of existing known raising small building block build structural seismic capacity mainly contains two classes: a class is to adopt stem stem or join the reinforcing bar shearing resistance in masonry: another kind of is to have adopted interlocking block, by the anti-shear concrete at the mutual snap-in of building block position.All be to be the means of antidetonation to improve shear strength of masonry singlely.
USPO's disclosed 3430403 patents in 1969 are that metal garden tube is inserted in the masonry circular hole of consistency from top to bottom, in the hole, inject concrete again, concrete runs through metal bobbin and the circular hole that is in line, in masonry, form the stem stem of a thin diameter, many thin stem stem dense arrangement can improve the rigidity of masonry.This thin stem stem and China arrangement of reinforcement stem stem commonly used is at present compared, should the arrangement of reinforcement stem stem more through squeezing rationally.And metal cylinder is understood in the time internal corrosion than building much shorter service life because of it, and loses efficacy, so should not regard the reliable primary structure member of permanent construction as.
The objective of the invention is: the ring-type connector that in masonry, adopts spline between the neighbouring masonry, with the mortar joint shear strength of improving the standard, adopt this connector of masonry mortar build-in of high-strength high-plasticity distortion simultaneously, alleviate the load effect of seismic forces, make masonry have damping antidetonation dual-use function masonry.Above-mentioned purpose of the present invention is achieved in that
Adopt the profile that sufficiently high concrete prefabricated circular or oval, polygon of intensity etc. and fragment of brick form adapt and the ring-type or the tabular connector of size, arrangement of steel wires in case of necessity can connector, destroy or the destruction of other form to guarantee that connector did not bend before shear failure, when earthquake takes place, can bear the horizontal earthquake scissors reliably.With masonry mortar the connector embedding is built on masonry mortar joint position neighbouring building block seat slurry face and slurry surface and to run through mortar joint in that reserve and the column pit that connector appearance and size compensates mutually, resist the horizontal shear of two skin blockhouses.Two planar annulars at connector are distributing and the vertical serrate slot of ring Zhou Fangxiang with all sides of outer shroud, same serrate slot is also distributing in the plane of pit and side, and extend on seat slurry face and the slurry surface of building block, all facewidth all are slightly larger than groove width, make that tooth can not embedded groove in.After pit was built in the connector embedding, masonry mortar promptly was squeezed in the teeth groove in connector and hole, formed many profile of tooth wedge keys, realized firm connection between two-layer building block up and down and the connector three by these wedge keys.When mortar strength and fitting intensity are enough high, can think that the masonry in the masonry destroys under action of horizontal seismic before, connector and mortar can not destroy.
With a kind of masonry mortar (claiming that " absorbing mortar " the applicant divides an application) that has than high-tensile and plastic deformation energy dissipation's ability the connecting piece embedding that has serrate slot is built in having the pit of serrate slot, can produce significant damping anti seismic efficiency.
To studies show that of building structure seismic forces: the ductility of the seismic load of structural system and structure self is relevant, along with the ductility factor of structure increases the corresponding reduction of seismic load.Hence one can see that, if admissible structure has certain plastic strain, seismic load is with corresponding reduction.
The present invention builds with the absorbing mortar embedding between connector and pit, when adjacent up and down between the two-layer building block owing to earthquake or other reason produces horizontal shear, when relative displacement trend is arranged, pocket wall compressing absorbing mortar, the absorbing mortar of different azimuth respectively pressurized, different external force such as draw, cut, and produce bigger plastic strain.The absorbing mortar that is evenly distributed in each position of masonry produces plastic strain dissipation seismic energy simultaneously, can alleviate the adverse effect of earthquake to structure.After absorbing mortar all destroyed, the horizontal earthquake shearing then all was transferred to connector and bears.Absorbing mortar as the first line of defence of masonry antidetonation, connector as defence line, second road, embodied the spirit of four an article or item in a contracts of GBJ11-89 earthquake resistant code 2.3.2 bar comparatively all sidedly, be that power transmission is clear and definite, multi-way prevention, necessary strength, deformability, energy dissipation capacity, stiffness and strength distribute rationally.
Another technology of the present invention is: be prefabricated into the tablet that compensates mutually with the pit bodily form and size with pea gravel concreten or cement mortar, pointing hides hollow fragment of brick hole in recessed resisting, promptly on the building block slurry surface, obtain more smooth interface, for component and fitting or other purposes such as build collar tie beam, windowsill, bear down on one.
Advantage of the present invention is: can adjust the horizontal mortar joint shear strength of masonry enough highly as required, and strength and stiffness distribute relatively more balanced.Brick body plastic degeneration ability improves can the reduction seismic load.The material that a small amount of stress performance is good is concentrated and is used at the mortar joint position of brick body weakness, and materials are economized, and the masonry deadweight increases seldom.The specification of building block, piece type, kind need not change.Can adjust kind, the consumption of connector and masonry mortar neatly according to the different requirement of strength of masonry.Improve masonry horizontal earthquake shear strength through squeezing rationally than the simple concrete-core column that adopts, and do not influence stem stem and reinforced steel are set in masonry.Building by laying bricks or stones aspect the skill and technique, the present invention builds the operation of connecting piece except that increasing by one embedding, and the custom brick-building art is seldom changed, and is easy to carry out in the operator.
Accompanying drawing 1 is a schematic diagram of the present invention, and it has represented that the present invention is applied to the embodiment that the little building block group of concrete hollow is built.
1 describe embodiments of the invention in detail with reference to the accompanying drawings, as shown in the figure, connector 1 is the precast concrete garden ring of square-section, embedding is built in the adjacent horizontal mortar joint position between the two-layer building block 2 up and down, half highly embeds the pit 4 on the slurry surface 3, half highly embeds the pit on the slurry face 5, the outer shroud of connector week side 6 and up and down two planar annulars 7 and the plane 8 of pit and the surface of side 9 serrate slot is arranged, and extend on a slurry face and the slurry surface from the pit side.
