Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Suitable for the prefabricated shear connections structure of hollowed-block masonry, Fig. 1-2 is referred to, its inventive point is：Shear connections
Structure 1 is integrally provided at the upper hypodermis layering of masonry structure.Shear connections structure supports gusset 1-1 by two block structure identicals
Formed with agent on crack resistance of concrete block 1-2；Support gusset is the zigzag structure being made up of the vertical edge of widthwise edge and connection widthwise edge.Two
Block support gusset is symmetrical set and is arranged in pairs in a cavity of building-block 2 in the horizontal direction, two blocks of support gussets
Upper horizontal edge be respectively supported on the rib wall of building block cavity 2-1 both sides and form cementation by mortar and two side rib walls and be connected.It is mixed
It is square block to coagulate native shearing-resistance blocks, and the top of agent on crack resistance of concrete block is embedded with suspension ring 1-3, and agent on crack resistance of concrete block is arranged on two pieces of supports
Between gusset, and support is taken on two pieces of lower horizontal edges for supporting gusset, the top half insertion epithelium building block of agent on crack resistance of concrete block is empty
Intracavitary, the latter half are embedded in hypodermis building block cavity, and agent on crack resistance of concrete block passes through the mortar 1-4 being filled in outside its surrounding and two
The internal chamber wall of support angle plate and building-block forms viscous fixed connection.The effect of above-mentioned suspension ring is：It is accurate by agent on crack resistance of concrete block to be easy to
Lifting is easy to the progress of building construction to the specified location in building-block cavity.The upper horizontal edge of above-mentioned support gusset and lower horizontal stroke
Side need to ensure one fixed width, be consolidated with ensuring to support to overlap between gusset and building block seat slurry face and agent on crack resistance of concrete block.
In above-mentioned shear connections structure, anti-shear concrete block size (including length, width and height) should be empty according to building block
Chamber size is prefabricated to be formed, and the height and the width of agent on crack resistance of concrete block should ensure that it has connecing for abundance with upper hypodermis building block cavity inner wall
Contacting surface is accumulated, and the length of agent on crack resistance of concrete block should ensure that it is put into convenient construction when in building block cavity.In the utility model, coagulation
Native shearing-resistance blocks it is highly preferred for the 2/5~2/4 of building-block cavity height, i.e., be highly 1/ with being engaged for upper hypodermis building block
5~1/4.The width of agent on crack resistance of concrete block is the 1/3~1/2 of building-block cavity width；Along long side direction, agent on crack resistance of concrete block
Two lateral surfaces and two corresponding madial walls of building-block cavity between respectively stay 15~20mm gap.Agent on crack resistance of concrete block uses
Above-mentioned size, on the one hand can reach preferable snap-in force with building-block, on the other hand reserve enough construction spaces, convenient
Construction.
Using the masonry wall of shear connections structure, Fig. 1 and 2 is referred to, masonry wall is by more skin concrete small size hollow building blocks
Build by laying bricks or stones and form, any adjacent two skins building block is bonded by mortar and uses the fissure of displacement to overlap, and the lap of splice is the half of building block length；
Making two cavitys of every piece of building block, each a cavity is corresponding with two pieces of building blocks that its hypodermis is overlapped respectively, and its inventive point is：
In any layer of masonry wall at hypodermis layering, one group of above-mentioned shear connections structure, and phase up and down are installed at interval of a cavity
Adjacent two layers shear connections structure is in interlaced arrangement successively.
The construction method of masonry wall, referring to following construction procedure：
For S1 before first skin concrete small size hollow building block is built by laying bricks or stones, first choice first spreads one layer of bed load slurry on basal plane, treats bed load
Slurry piles up first skin building block after completing on bed load slurry.
S2 lays mortar in the first skin building block upper surface puzzled, and at interval of a building block cavity, direction is cut along masonry
A pair of support gussets are arranged symmetrically, the upper horizontal edge of two support gussets is overlapped to the two side rib walls for being fixed on cavity respectively by mortar
On, the other end of two support gussets is in suspended state in cavity, treats subsequently to carry the use of agent on crack resistance of concrete block.
S3 starts to pile up the second skin building block, adjacent two skin is built after the support gusset in first skin building block cavity arranges into
Block is overlapped using the fissure of displacement, and the lap of splice is the half of building block length, two cavitys of every piece of building block is taken respectively with its hypodermis
Each a cavity is corresponding for the two pieces of building blocks connect；
After S4 the second skin building blocks puzzle, between multiple agent on crack resistance of concrete blocks are placed on into multipair support gusset one by one, it is used in combination
Mortar is closely knit by the gap filling between agent on crack resistance of concrete block and two support gussets and building block cavity inner wall, makes agent on crack resistance of concrete block
Closely it is engaged with upper hypodermis building block；
Agent on crack resistance of concrete block at first of building block layering of S5 arrange into it is rear, the second skin building block upper surface lay sand
Slurry, then at interval of a building block cavity, cut direction along masonry and be arranged symmetrically and fix a pair of support gussets, support this layer
Gusset and the support gusset arranged at lower floor layering in being staggeredly arranged one by one, after the completion of gusset arrangement to be supported, the He of repeat step 3
Step 4, by that analogy, a skin building block has often been built by laying bricks or stones to be intended to arrange by a pair of support gussets and mix in the skin building block spaced cavities
The shear connections structure that solidifying native shearing-resistance blocks are formed, and the shear connections structure of the neighbouring layer of guarantee is in interlaced arrangement, until building
Top skin building-block is built.
Because agent on crack resistance of concrete block is needed between being embedded in adjacent skin building block, therefore push up and be not required to set in skin building block cavity.To
Before placing agent on crack resistance of concrete block in building block cavity, it need to ensure that supporting gusset to consolidate is overlapped among mortar joint, otherwise puts too early
Putting agent on crack resistance of concrete block will impact to the intensity of mortar at mortar joint.Therefore, to ensure at mortar joint mortar strength not by anti-
The influence of attachment structure is cut, can be hung after mortar reaches some strength using the suspension hook of agent on crack resistance of concrete block upper surface
Enter into cavity, it is finally with mortar that the gap filling between agent on crack resistance of concrete block and building block cavity inner wall and support gusset is close again
It is real.
