Description
Technical field
The invention belongs to building structure field, more particularly to a kind of hollowed-block masonry structure of built-in prefabricated shearing-resistance blocks.
Background technology
Masonry structure is all widely used as a kind of most area of excellent structural system in China, but is being permitted
Have been found that masonry structure building all receives different degrees of damage in more earthquake disasters, particularly China occurs in recent years
The rural area masonry house of earthquake all collapses substantially, causes great economy and personal casualty loss.Shearing strength of tracing it to its cause deficiency
It is the principal element for causing house collapse, this is because the shear resistance of masonry structure is mainly rubbing by the mortar between masonry
Wipe power and cohesive force to provide, once the shearing that masonry is subject to is excessive, building block will produce sliding between layers, and so far wall has been
Through losing bearing capacity.
The content of the invention
The building-block that the present invention provides a kind of built-in anti-shear block to solve technical problem present in known technology is built
Body structure, the hollowed-block masonry structure can significantly improve the shear resistance of wall when masonry is subject to larger shearing, subtract
Less or avoid since mortar strength is too low so that masonry slides between layers, improving the overall stability of masonry structure.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：
A kind of hollowed-block masonry structure of built-in prefabricated shearing-resistance blocks, hollowed-block masonry structure is by concrete hollow block
Build by laying bricks or stones and form in the way of neighbouring fault seam overlap joint, it is characterised in that：In two concrete hollow blocks to connect up and down
Align prefabricated shearing-resistance blocks be provided with cavity, the prefabricated shearing-resistance blocks are by shearing-resistance blocks body part and support cross arm part structure
Into support cross arm part is in rod-shaped or flat strip, and the diameter or thickness of support cross arm are less than the horizontal mortar joint of masonry structure
Thickness；The interlude of support cross arm part is embedded in shearing-resistance blocks body part, and the both ends of support cross arm are respectively from shearing-resistance blocks sheet
The both sides of body are stretched out and are supported on the two side rib wall of cavity of lower part concrete hollow block, make the upper of shearing-resistance blocks body part
Half part and the latter half are respectively protruding into the cavity of corresponding top concrete hollow block and corresponding lower part concrete
In the cavity of building-block；Between the surrounding of shearing-resistance blocks body part and the corresponding cavity inner wall of concrete hollow block up and down
Filled with mortar, vertical mortar mortar joint is formed.
Preferably：In whole hollowed-block masonry structure, side that prefabricated shearing-resistance blocks stagger successively according to neighbouring layer
Formula is evenly arranged.
Preferably：The cross-arm of prefabricated shearing-resistance blocks is single or multiple, and multiple cross-arms are uniformly distributed in same plane.
Preferably：Support cross arm part is in line-styled.
Preferably：Support cross arm part is that the vertical edge part of support cross arm hooks to lean against mixes with lower part in horizontal positioned L-type
In the cavity wall of the solidifying soil building-block concrete hollow block adjacent with layer.
Preferably：Support cross arm part is less than 6mm reinforcing bars or steel wire for diameter.
Preferably：Support cross arm part is less than the stalloy of 6mm for thickness.
Preferably：The shape of shearing-resistance blocks body part is cuboid, dog bone or the pyramid bodily form at four rounding angles of band.
The present invention has the advantages and positive effects of：
1st, for this hollowed-block masonry structure by setting support cross arm in prefabricated shearing-resistance blocks, support cross arm is supported in building block
On the rib wall of cavity both sides, to limit the vertical displacement of prefabricated shearing-resistance blocks, make the positioning of prefabricated shearing-resistance blocks more accurate, ensure that
Hollowed-block masonry structure is when being subject to shearing action, in the cavity for occuping upper and lower building block that prefabricated shearing-resistance blocks can divide equally.
2nd, this hollowed-block masonry structure is prefabricated anti-by being inserted into the cavity of the concrete hollow block to connect up and down
Block, realizes the shear connections of upper and lower concrete hollow block, so that when masonry is subject to larger shearing, significantly improves
The shear resistance of masonry, and then be reduced or avoided since mortar strength is too low so that masonry slides between layers, improve block
The overall stability of body structure.
3rd, in this hollowed-block masonry structure, prefabricated shearing-resistance blocks directly take support by support cross arm in the building block positioned at lower floor
On two side rib walls of cavity, the construction on existing hollowed-block masonry structure is aligned without influence, and easy to upper and lower concrete segment,
So as to be conducive to improve construction efficiency.
