Description
Technical field
The utility model is related to a kind of assembled sealing up screw to reinforce one side formwork structure.
Background technology
Under the feelings being limited in place are wished, the form work engineering of underground engineering shear wall is generally added using unilateral die body system
Gu being so just well positioned to meet the needs of engineering, without slope, the mould material of one side can be saved.One side formwork reinforcing is applied
Oneself uses work technology in numerous engineering projects at present.
In the single side formwork engineering of part, employ sealing up screw and carry out single formwork reinforcement.Sealing up screw method carries out single
Collateral mould has the advantages that following several respects：(1) stress system is identical with common two-sided formwork, uses and draws bolt pattern, by
Power form is comparatively safe；(2) formwork and form removal are convenient and efficient, skilled operation, and manpower consumption amount is close with common two-sided formwork；
(3) exterior wall can with floor girder and board primary concreting, it is suitable with conventional two-sided formwork construction speed.
In traditional sealing up screw carries out single mode plate reinforcement means, there are two types of connection sides with supporting construction for sealing up screw
Formula.The first is to pass through the steel planting on foundation pit supporting construction or ground-connecting-wall；It is for second, by supporting construction concrete
Protective layer is cut, and is then connected sealing up screw with supporting construction reinforcement welding.On the one hand both connection modes need to spend
A large amount of costs of labor and time cost, another aspect both approaches are required to the regular arrangement that sealing up screw is embarked on journey in column,
It can ensure to lead stupefied horizontal continuity or vertical continuous, reasonable stress.But it is difficult to realize in practical operation.
In traditional sealing up screw carries out single mode plate reinforcement means, the external labeling type waterproof roll preformed hole at sealing up screw
Hole is suspended on after supporting construction and cuts hole and pass through external labeling type waterproof roll convenient for sealing up screw.If first by sealing up screw
It is fixed in supporting construction, it is rear to hang paving external labeling type waterproof roll, it is necessary to one side paving coiled material, while drilling on coiled material.
To ensure that coiled material is smooth, it is necessary to ensure that sealing up screw perpendicular to branch mask, will so influence outer patch in boring procedure after paving
Formula coiled material installation effectiveness, while external labeling type coiled material is drilled with substantial amounts of hole, can not form complete water-proof system.Sealing up screw is broken
The globality of the outer waterproof of exterior wall is broken, a large amount of bolts hole are added on waterproof layer, repairing is time-consuming and laborious, and can not ensure own
The waterproof repairing of bolt hole can meet antiseep requirement.
In traditional sealing up screw carries out single mode plate reinforcement means, sealing up screw is repaiied after can not cutting on the outside of outer shear wall
It mends, although there is provided sealing steel discs, after the several years, bolt corrosion can form many penetrating passages, greatly increase outside underground
The possibility that wall seeps water in the future.
Utility model content
The utility model solve the deficiencies in the prior art and provide a kind of speed of application faster, reasonable stress, reinforce material
Material is conventional material, is lifted without large scale equipment, and the relatively low assembled sealing up screw of construction cost reinforces one side formwork
Structure and construction method.
To achieve these goals, the utility model provides following technical solution：A kind of sealing up screw reinforces unilateral mould
Harden structure, including foundation pit supporting construction and template, the foundation pit supporting construction in supporting construction steel reinforcement cage by pouring supporting knot
Structure concrete is formed, and the supporting construction steel reinforcement cage is connected and composed by vertical applied force reinforcing bar by ring-shaped stirrup and reinforcement stirrup,

The part that bar stretches out the foundation pit supporting construction is vertical with foundation pit supporting construction, and multiple foundation pit supporting constructions are laid side by side,
So that towards template, sealing up screw is being fixed in the template equipped with the face where pre-buried pull rod for foundation pit supporting construction, it is described
Sealing up screw is connected by branch sleeve with pre-buried pull rod.
The template is stupefied including panel, secondary stupefied and master, and the sealing up screw passes through positioning screw cap, butterfly button and reinforces nut
Be located on panel, the front of the panel towards foundation pit supporting construction, the back side of the panel by secondary stupefied and main stupefied support,
The part of the same sealing up screw axially laid through panel be installed in two masters it is stupefied, and by being mounted on sealing up screw
Butterfly button and reinforce nut compressing it is secondary it is stupefied on, the panel front determined by the positioning screw cap being mounted on sealing up screw
Position ensures the spacing between panel and foundation pit supporting construction.
The foundation pit supporting construction is equipped with basal plane screed-coat towards template one side, and the basal plane screed-coat is parallel with template
It sets.
Adjacent Pit supporting construction junction is axially disposed the semicircle pvc pipe for preventing infiltration.By foundation pit supporting construction
The water that outside soil layer penetrates is along semicircle pvc pipe water conservancy diversion, and the waterproof material for preventing from being sprayed on supporting construction screed-coat is because of soil
The layer excessive breakage of seepage water pressure.
Waterproof layer is coated on the basal plane screed-coat and the opposite face of template, the waterproof layer is rapid hardening rubber
Glue flexible spray filmogen.
The branch sleeve is made of stainless steel, is non-through hole in the middle part of branch sleeve, has among non-through hole and pass through
Stainless steel separator is isolated.
This single side formwork bracing means has the advantages that：
(1) pull rod is reserved according to certain rule can ensure that sealing up screw transverse and longitudinal is embarked on journey into advance on supporting construction steel reinforcement cage
Row are reinforced convenient for sealing up screw, and foundation pit supporting construction protective layer welded reinforcement or bar planting, speed of application are cut compared with tradition
Faster；
(2) sealing up screw is connected on pre-buried pull rod, reasonable stress, be can effectively prevent concrete and is risen mould；
(3) waterproof material can effectively ensure construction in foundation pit branch using flexible sprays filmogens such as spraying rapid hardening rubber
Waterproof material on protection structure basal plane forms closing rounded system；
(4) branch sleeve is made of stainless steel, and to be non-through, there is stainless steel separator in centre, can effectively prevent sealing
Screw rod corrosion, rust are worn so as to cause exterior wall leakage；
(5) it is main it is stupefied for double steel pipe it is vertical, can to avoid on different foundation pit supporting constructions with arrange pre-buried pull rod absolute altitude occur compared with
Large deviation still can be reinforced effectively；
(6) this single side formwork reinforcing mode can be adapted for the shear wall one side formwork reinforcing of any height；
(7) English truss single side formwork reinforcing area was not applied in shear wall corner or other limited spaces should add
Gu mode.
(8) material that this reinforcement means uses is conventional material, is lifted without large scale equipment, construction cost compared with
It is low.
In conclusion using this structure construction speed faster, reasonable stress, reinforcement material be conventional material, without big
Type equipment is lifted, and construction cost is relatively low.
