Embodiment
Disengaging type formwork jumbo proposed by the present invention, chassis component and underground are led to below in conjunction with the drawings and specific embodiments
Road concrete construction method is described in further detail.According to following explanation and claims, advantages and features of the invention
It will become apparent from.It need to illustrate in addition, accompanying drawing uses using very simplified form and non-accurately ratio, only to side
Just the purpose of the embodiment of the present invention, is lucidly aided in illustrating.For sake of convenience, " on ", " under " described below and accompanying drawing
Upper and lower direction is consistent, but this can not turn into the limitation of technical solution of the present invention.
Embodiment one
Disengaging type formwork jumbo, chassis component and its underpass for describing the present invention in detail with reference to Fig. 1 to Fig. 5 mix
Coagulate the construction method of soil.
As shown in figure 1, a kind of disengaging type formwork jumbo, for underpass concrete pouring construction, including backform pallet
Car 31, side template 10 and vertical supporting bar 20, side template 10 are distributed in the both sides of top template chassis 31 and by plank sheathings 14
It is connected with top template chassis 31；The bottom of side template 10 is provided with moving guide rail 11, and moving guide rail 11 is with being arranged at vertical supporting bar
Mobile pulley 21 on 20, which coordinates, drives side template 10 to vertically move.
Top template chassis 31 includes being arranged side by side and by least two top template trolley units of detachable connection, often
Individual top template trolley unit includes top template 31, walking mechanism 32 and column 33, and walking mechanism 32 and column 33 are tightly supportted in top
The lower section of template 31, mobile pulley 21 is detachable to be installed on the column 33 of side template 10.
Specifically, according to construction requirement, the concreting work of underpass bottom plate 40, Ran Houli are completed in first construction
With the concrete pouring construction that underpass structure roof and structure side wall are carried out using disengaging type formwork jumbo.Formwork jumbo exists
The over-assemble of underpass bottom plate 40 is completed.Because the concrete of structure roof and structure side wall reaches supporting required for design strength
Time difference is protected, according to job specfication, the usual structure side wall concrete curing time is the structure roof concrete curing time
Half.Therefore, after the structure side wall concrete strength of previous construction section reaches design requirement, by the form removal of side template 10, cleaning
The pouring construction that next construction section carries out structure side wall concrete is sent into afterwards, so as to save the engineering time.The He of top template 31
It is attached between side template 10 by plank sheathing 14, increases the space of the transverse shifting of side template 10, facilitates side template 10
Cleaning, reduce the time of the foregoing template of on-site consolidation, simplify difficulty of processing.
Especially, side template 10 also includes lateral retractor device (not shown), and lateral retractor device includes being installed on column
Transverse moving support 15 and side template Shift cylinder 16 on 33, side template Shift cylinder 16 is detachable to be installed on column 33
Between walking mechanism 32, side template Shift cylinder 16 drives side template 10 to be stretched along transverse moving support 15.
Certainly, in order to be tumbled when preventing side template 10 from moving, ensure side template 10 along being arranged at moving on column 33
Pulley 21 does linear motion until reaching specified location, and side template 10 is provided with top moving leader 13 close to the side of column 33.
It is preferred that in order to meet the force stability of side template 10, side template 10 passes through transverse support bar 12 and homonymy
The detachable connection of column 33.Detachable connection includes be hinged, bolt connection and bearing pin connection etc., this hair in the present embodiment
It is bright not to be limited herein.
Especially, in order to further shorten the concrete construction cycle of underpass, and cost is saved, improves construction
Quality, a kind of chassis component is provided in another embodiment of the invention.The chassis component is included along the longitudinal direction of underpass
Two top template chassis being coaxially disposed and a set of side template, the mobile pulley of two top template chassis lower ends are docked mutually, made
Obtain side template longitudinal sliding motion on formwork jumbo component.Two top template chassis are respectively top template chassis one and top template chassis
Two.When the concrete strength of the construction section structure side wall where top template chassis one reaches design requirement, such as at 8-12 days, tear open
Except the side template 10 on top template chassis one, and by the cross-direction shrinkage certain distance of side template 10, such as 70 centimetres, side template is carried out
10 cleaning, then side template 10 moves along pulley 21 and is moved at the top template chassis two of next construction section, and pacifies
Loaded on top template chassis two, the structure roof of place construction section of top template chassis two and pouring for structure side wall concrete are carried out
Build work.When concrete strength of structure side wall reaches design requirement at this, the foregoing associative operation to side template 10 is repeated；
At the same time, the concrete strength of the structure roof of the place construction section of top template chassis one is also up to design requirement, thus can
To remove the top template 31 of top template chassis one, and top template 31 is caused to pass through top template chassis under the drive of walking mechanism 32
Two enter the 3rd construction section, will move to the 3rd construction section positioned at the side template 10 of the place construction section of top template chassis two, and install
In on top template chassis one；And monolithic concrete will be carried out to the underpass structure roof of the 3rd construction section and structure side wall
Pour.That is, chassis component includes two top template chassis and a set of side template 10, two top template chassis are one in front and one in back
Set, respectively positioned at adjacent construction section；Realize that alternate cycles are constructed by a set of side template 10 and two top template chassis, it is real
Show the continuity of construction, improve efficiency of construction.
Further, top template chassis includes the top template trolley unit 1 of detachable connection, backform pallet successively
Car unit two (not shown) and top template trolley unit 3 314, top template trolley unit two are included in detachable connection
Between top template trolley unit 1, the small top plate 312 of detachable and middle top template trolley unit 2 313.In structure roof
After concrete strength reaches design requirement, top template 31 is removed, after top template chassis is decomposed, the backform after decomposing can be caused
The width of plate trolley unit is less than the width in the passageway of other top template chassis central post 33 composition, after convenient decompose
Top template trolley unit pass through another top template chassis and installed.Especially, there are lattice among underpass
During structure post, it may be such that the top template chassis after decomposing is driven to up to specified around lattice column by removing the small top plate of detachable and apply
Workshop section.
