Description
Technical field
The invention belongs to taper pile construction field in architectural engineering, more particularly to a kind of plug-in template for taper pile construction,
Auxiliary device and construction method.
Background technology
At present, developing rapidly with domestic and abroad bridge technology, multiarch bridge, Deck Arch Bridges, steel arch bridge etc. possess and have
The bridge structure that landscape effect is good, meet landform requires is arisen at the historic moment, and not only embodies the unique design level of designer, while
And the Engineering Projects for being related to taper pile in Arch Bridge Construction is more, under water taper pile is verified to a kind of of different types of rridges construction method
Relatively universal, the mostly taper pile of major diameter is designed as full face inclined steel-pipe pile, using tunneling boring impact holing, impact holing more
Equipment is also more ripe at home and abroad.
But design for the taper pile of minor radius, both at home and abroad without ripe construction technology and equipment, more using manually digging hole
Construction method, guarantees quality and the safety constructed, but the disadvantage of many quality controls is yet suffered from work progress, because tiltedly
The special construction principle of stake, in concreting process, because of gravity, concrete is ready that generation is caved in, and because the section of taper pile
There is certain oblique angle in direction.Therefore after taper pile pore-forming, during casting concrete, the shape of template of stake mouth and the sequencing of installation,
Construction method etc. all constrains the pouring quality of aperture concrete.
Because taper pile is during casting concrete, start casting concrete from side, concrete is poured on the upside of side event stake mouth
Build quality to ensure, concrete at taper pile stake mouth top closure is normally due to cannot vibrate, side casting concrete cannot be protected
The degree of compaction of card concrete above, concrete are more open, can only solve casting concrete above using rear compensating method mostly
Problem, but after the effect poured it is generally bad, after concrete formation form removal, step is more apparent, apparent mass extreme difference, another intensity
There is open defect, directly affect the total quality of taper pile；Scene adopts how spliced bamboo slab rubber, using repeatedly splicing,
Can just complete to pour, while bamboo slab rubber is difficult to fix on light-gauge taper pile, it is many using being manually fixed at present, pouring
Hand fit, method is needed relatively to fall behind while concrete, man efficiency is low, after the completion of pouring, layer holds again above taper pile
Be also easy to produce concrete to come off and cavitation, and main cause to be the incorrect and Formwork Installation Method that template is adopted unreasonable make
Into.
As shown in figure 1, before taper pile pore-forming after-pouring concrete, the concrete knot that taper pile includes that inwall has sprayed and solidifies
Structure, includes steel arch-shelf 4 inside the xoncrete structure, include equally distributed reinforced mesh reinforcing bar 7, institute on the outside of the steel arch-shelf 4
State reinforced mesh reinforcing bar 7 and leave extension elongation；It is equally distributed steel reinforcement cage vertical reinforcement 8 on the inside of the steel arch-shelf 4, this is vertical
Reinforcing bar 8 leaves extension elongation, and the position and distribution density of all reinforced mesh reinforcing bars 7 and vertical reinforcement 8 are all counted before construction
Calculate, reinforced mesh reinforcing bar 7 is relatively thin, vertical reinforcement 8 is relatively thick, therefore 7 position of reinforced mesh reinforcing bar is unstable, vertical reinforcement 8
Put more stable, and because fixation of the steel reinforcement cage also including equally distributed transverse steel so that the position of vertical reinforcement 8 is more steady
It is fixed.
As the template for designing is assembled by polylith, it is fixed up where there are many deficiencies, coordinates between template
Also displacement is susceptible to, is easily occurred swollen film after pouring and is run film phenomenon, have a strong impact on the quality of taper pile.
The content of the invention

In the present invention, the technique effect of above scheme is realized in：
In the present invention, the plug-in template of the present invention includes end template, middle template and the top template for cooperating, can basis
Construction speed is installed and casting concrete successively from bottom to top, and casting process is more reasonable, the first outer side perforation, the
Two outer side perforations and the 3rd outer side perforation adapt to reinforced mesh reinforcing bar, side perforation in described first, in second side perforation and
In 3rd, side perforation adapts to vertical reinforcement, so as to play a part of to limit lateral displacement；End template is only needed after being installed in place
Adjacent vertical reinforcement is passed through into steel wire lashing or welding can limit vertical displacement, middle template and top template vertical displacement are limited
Mode is identical；The clamp device of the present invention can be anchored on after the completion of model sheetinstallat on the outside of reinforced mesh reinforcing bar, by drawing spiral shell
Bolt is fixedly connected, and removes after concrete setting, and program fastening effect is substantially, easy for installation.Heretofore described fixation
Frame includes the first connecting plate, the second connecting plate and the 3rd connecting plate, and the locking mechanism is conducive to locking between template, prevents template
Between be subjected to displacement, improve the fastening effect between plug-in template, solve easily go out again after pouring swollen film and run film phenomenon
Problem.In in the plug-in template of the present invention, template top is sunk structure, and the structure is conducive to concreting convenient.This
In bright plug-in template, the first outer side perforation, the second outer side perforation and the 3rd outer side perforation are cruciform shape, the program gram
The unstable defect of reinforced mesh reinforcement location is taken so that the suitability of perforation is higher, and fixed effect is more preferable.The present invention's is outer
Hanging template also includes guiding gutter, and the water conservancy diversion trench bottom is removably connected to top template upper surface, the water conservancy diversion trench bottom with
The opening adaptation, because guiding gutter is detachable, after concreting is completed and solidified, operating personnel can pull down guiding gutter and whole
External to hang template, the program has ensured that the concreting of top template position is complete, after concrete formation form removal, no step, and table
Preferably, another intensity is obviously improved appearance quality, and the total quality of taper pile is protected.Guiding gutter of the present invention is to be bent upwards
Structure；Locking clip is combined with guiding gutter also.The program is conducive to casting concrete convenient, is more beneficial for realizing tearing open for guiding gutter
Unload and install.The first drop handle is provided with the middle part of end template of the present invention, the second drop handle in the middle part of the middle template, is provided with, it is described
