Abstract
A connecting beam structure of a pile top of a double-row type steel cement soil mixing pile is composed of an upper reinforced concrete plate and a lower reinforced concrete plate, wherein an isolation layer is arranged between the lower reinforced concrete plate and the internal section steel of the mixing pile; the lower reinforced concrete plate is wrapped in the upper reinforced concrete plate. The invention can form a consolidation node on the pile top of the mixing pile, fully exert the mechanical properties of large rigidity and small deformation of the double-row pile, reduce the displacement deformation of the supporting structure and avoid influencing the extraction of the section steel after the supporting is finished.
Description
Technical field:
The invention belongs to building engineering field, in particular to a kind of coupling beam knot of double row type steel cement mixing method stake top
Structure.
Background technique:
Fashioned iron cement mixing method is often used in architectural engineering pit supporting, and it is commonly used be Single row pillars branch
Shield form.When using the cement mixing method supporting of double row type steel, the crown beam knot of conventional single fashioned iron Soil-cement stake top
Structure will be unable to that crown beam and support pile is made to form consolidated node, (usually adopt this is because crown beam must be effectively isolated between fashioned iron
It is isolated with the plank sheathing of foamed plastics or thickness 10mm or so), to extract fashioned iron after supporting terminates, and because isolation produces
Raw gap will make to produce relative sliding displacement between fashioned iron and crown beam, therefore be unable to reach the effect of consolidation.When can not be formed
When consolidated node, double-row pile will generate biggish displacement deformation as supporting construction.
Fashioned iron will be first with crown beam as the jack base for loosening fashioned iron when extracting, therefore crown beam is that fashioned iron soil cement stirs
Mix one of essential component part of stake (crown beam while having both other function).
Currently, there is end item foundation pit using the cement mixing method supporting of double row type steel, coupling beam still uses traditional
The crown beam of Single row pillars and the connection type of fashioned iron, do not efficiently solve this problem.
Summary of the invention:
It is an object of the invention to overcome the defect of existing crown beam Yu fashioned iron type of attachment, a kind of double row type molten steel mud is provided
The coupling beam structure of soil stirring stake top, the coupling beam structure can both make to stir stake top formation consolidated node, give full play to double-row pile
The mechanical property that rigidity is big, deformation is small, reduces the displacement deformation of supporting construction, and does not influence the extraction of fashioned iron after supporting.
As above design, the present invention is achieved by the following technical solutions:
A kind of coupling beam structure of double row type steel cement mixing method stake top, is made of upper and lower two parts armoured concrete slab,
Separation layer is housed, upper reinforcement concrete slab is by the two blocks of reinforcing bars in left and right in lower rebar concrete slab and mixing pile between fashioned iron
The overall structure that concrete slab is formed by connecting by reinforced concrete coupling beams, upper reinforcement concrete slab and fashioned iron in mixing pile are straight
Contact pours into overall structure；Lower rebar concrete slab is wrapped in upper reinforcement concrete slab.
Above-mentioned upper reinforcement concrete slab will turn under two sides and wrap up lower rebar concrete slab.
Flexible material separation layer is housed between above-mentioned upper and lower two parts armoured concrete slab.
Above-mentioned lower rebar concrete slab is the cast-in-situ reinforced concrete slab of a monolith thickness 200mm.
Two pieces of the left and right armoured concrete slab of above-mentioned upper reinforcement concrete slab is with a thickness of 500mm.
The advantages and benefits of the present invention are:
1, the present invention can meet the consolidation requirement of double-row pile coupling beam and stake using upper reinforcement concrete slab, give full play to double
The advantage that campshed rigidity is big, deformation is small.
2, it is isolated between lower rebar concrete slab of the present invention and fashioned iron in mixing pile with materials such as foamed plastics, is not influenced
Fashioned iron is smoothly extracted, while lower rebar concrete slab can be used as jack base when extracting fashioned iron, therefore remain fashioned iron
The advantages of cement mixing method low cost.
3) upper reinforcement concrete slab of the present invention and coupling beam can limit left and right two in two sides package lower rebar concrete slab
The horizontal alternate displacement of block armoured concrete slab is allowed to be formed as a stress entirety, is conducive to eliminate the non-consolidation section of lower panel
The adverse effect that point generates.
4) can be worked together between upper reinforcement concrete slab and coupling beam and lower rebar concrete slab of the present invention and
Separately remove.
5) present invention is easy for construction, quality controllable.

Specific embodiment:
Below by specific embodiment, the invention will be further described, and it is not limit that following embodiment, which is descriptive,
Qualitatively, this does not limit the scope of protection of the present invention.
It is as shown in the figure: a kind of coupling beam structure of double row type steel cement mixing method stake top, by upper and lower two parts reinforced concrete
Native plate 2,3 forms, and its underpart armoured concrete slab is the cast-in-situ reinforced concrete slab of a monolith thickness 200mm, the plate and stirring
Equipped with the separation layer 4 made of foamed plastics (or plank sheathing, malthoid etc.) between fashioned iron in stake 5.Upper reinforcement concrete slab 2 is
The cast-in-situ reinforced concrete slab of two pieces of thickness 500mm, and an overall structure being formed by connecting by reinforced concrete coupling beams 2,
Lower rebar concrete slab 3 is wrapped up by being turned under 2 two sides of upper reinforcement concrete slab.Upper reinforcement concrete slab 2 and mixing pile 5
Interior fashioned iron 6 directly contacts, and pours as an entirety.It can be isolated with flexible material layer 1 between upper and lower armoured concrete slab.
Application method of the invention is: after supporting, upper board first abolished, retains lower panel, then pulls out fashioned iron,
Finally remove lower panel.It comprises the concrete steps that
1, after in the pile body part of related cement mixing method, construction is finished, pile crown soil is excavated by design altitude, clearly
Relevant surfaces dregs are managed, isolated material is wrapped up, then ties up muscle formwork and pour lower part board concrete.
2, the side form for removing lower rebar concrete slab, in upper reinforcement concrete slab and coupling beam and lower rebar concrete
The separation layer of one layer of plastic cloth or malthoid etc is spread between plate.
3, upper reinforcement concrete slab and coupling beam tie up muscle formwork casting concrete.
4, after supporting terminates, upper reinforcement concrete slab and coupling beam is first removed, must not pay attention to and damage lower panel.
