Description
Technical field
The present invention, about a kind of formwork erection method and structure, refers in particular to a kind of interlayer external wall construction seam
Place dissipates spells formwork erection method and structure.
Background technology
Xoncrete structure is mainly itemized greatly by reinforcing bar, template, concrete three and is constituted, wherein, and form fixer
Journey is the most complicated, and the subdivisional work that the amount of labour used is maximum, it has become affects construction quality, engineering
The key factor of progress.Although now widely popularize sizing masterplate, all-steel big shuttering etc., various its
Its new type formwork is also constantly occurring, but, dissipate and spell template with its low cost, convenient transportation, assembly
Flexibly etc. feature is still in occupation of major part market.But, along with construction quality requires more and more higher,
The shortcomings such as its piece, spillage, faulting of slab ends, deformation are more obvious, not only affect structural safety and
Presentation quality, also can increase the biggest later stage processing cost, affect carrying out of various work.Especially
Detailed treatment at interlayer external wall construction seam, spillage that piece the most sternly causes and faulting of slab ends are the most always
It it is the difficult problem of puzzlement people.Spillage and faulting of slab ends phenomenon once occur, deals with and bother very much, take a lot of work
Laborious more expensive, process not in time and affect image.
Therefore, each unit actively takes different measures to carry out pre-control, such as: have people at outer wall template
Bottom pad one elongated flitch, the method can reduce spillage, but faulting of slab ends phenomenon usually occurs；Someone is outside
Sponge strip set up by wall, and the method is higher to the completeest concrete wall outer edge flatness requirements, otherwise without
Method jam-packed, still there will be the phenomenon such as spillage and faulting of slab ends；Someone Os Draconis each time bottom wall form
Place adds a timber wedge, makes the adjacent body of wall of template, the method, and wood losses amount is big, and can pair cross-section size
Produce impact；Similar method is a lot, differ and with, but all cannot ensure template and the completeest concrete walls
Body is in close contact, thus tackles the problem at its root.
Summary of the invention
Because the problems referred to above, the invention provides to dissipate at a kind of interlayer external wall construction seam and spell formwork erection
Method, comprises the following steps:
(1) inner side template is installed and an absolute altitude is low at concrete exterior wall body of wall sidepiece to be poured
Outboard template in concrete floor top elevation；
(2) fixed form, described fixed form are placed along described outboard template horizontal full-length suitable for reading
Extend upward described concrete floor top board；
(3) built-in fitting is passed described in concrete exterior wall body of wall to be poured and described fixing mould
Plate；
(4) carry out the concreting of exterior wall and floor, after having poured, remove described interior side form
Plate and outboard template；
(5) repeat step (1) to (4), carry out installing of upper former and watering of concrete
Building, wherein, the outboard template of upper former installs based on described fixed form；
(6) after upper strata concreting completes, outside the fixed form of dismounting lower floor excision are stretched out
The built-in fitting of wall；
(7) repeat step (5) and (6), complete the construction of whole outer wall body.
Further improvement is that of the method, after step (2), also includes step (21):
In the outside of described inner side template, outboard template and fixed form, by through calculating the size determined
And spacing configures secondary joist, main joist and carries out reinforcing check.
Further improvement is that of the method, described built-in fitting is a pre embedded bolt, described pre embedded bolt
One end wear into concrete exterior wall body of wall to be poured, the other end of described pre embedded bolt stretches out to be poured
The concrete exterior wall body of wall built, and further pass through described fixed form.
Further improvement is that of the method, described pre embedded bolt wears into concrete exterior wall to be poured
One end of body of wall is welded with a vertical reinforcing bar.
In order to coordinate the enforcement of said method, present invention also offers and dissipate at a kind of interlayer external wall construction seam
Spell formwork structure, including propping up inner side template and the outside being located at the concrete exterior wall body of wall sidepiece built to be poured
Template, the absolute altitude of described outboard template is less than the absolute altitude of concrete floor top board by a preset value, along institute
State outboard template horizontal full-length suitable for reading and be placed with the width fixed form more than described preset value, and institute
State fixed form and be anchored on the concrete exterior wall body of wall after having poured by a built-in fitting.
Further improvement is that of this structure, described built-in fitting is a pre embedded bolt, described pre embedded bolt
One end wear into concrete exterior wall body of wall to be poured, the other end of described pre embedded bolt stretches out to be poured
The concrete exterior wall body of wall built.
Further improvement is that of this structure, described pre embedded bolt wears into concrete exterior wall to be poured
One end of body of wall is welded with a vertical reinforcing bar.
Use to dissipate at the interlayer external wall construction seam of the present invention and spell formwork erection method, poured concrete
After, do not remove fixed form and pre embedded bolt, only remove the template of remainder, erecting of pre embedded bolt
Straight reinforcing bar can form a mutual grasp with concrete, it is ensured that template firm.On installing
During layer outboard template, carrying out joining mould bottom it based on fixed form, above-mentioned same sample prescription is pressed at its top
Method configures, then by through calculating, the size determined and spacing configure secondary joist, main joist is gone forward side by side
Row reinforcing, check etc..After upper strata concreting completes, then remove bottom the outboard template of upper strata
Fixed form, and excision simultaneously stretches out the pre embedded bolt of exterior wall, so repeats construction, complete whole outside
The construction of wall.
Due to the fact that and have employed technique scheme, have the advantages that
1, owing to, during pouring levels concrete, fixed form remains the most motionless,
Ensure that the seamless combination of itself and concrete wall, it is to avoid spillage and faulting of slab ends phenomenon occur.
2, owing to having installed fixed form, make exterior wall other parts template has installed the base depended on
Plinth, it is simple to operation.
3, exceed the absolute altitude of floor top board due to fixed form, facilitate outboard template glacing flatness and
The inspection of sectional dimension and check.
4, after form removable, levels seam is tight, and mortar is full, and organoleptic quality is good, can be direct
Carry out decoration of exterior wall construction.
