Description
The application be the applying date be 20151214, application No. is 2015109295012, entitled minimum spacing separation
Formula Thin-Wall Piers template and its application, the artificial Shanghai Civil Engineering Co., Ltd. of Crec of application and the Shanghai Zhong Tie group of Engineering Bureau the
The divisional application of one Engineering Co., Ltd.
Technical field
The present invention relates to Thin-Wall Piers template and its applications, more specifically a kind of to apply in minimum spacing separate type thin-walled
Template in pier construction and its application.
Background technology
In existing technology, to eliminate the stress that continuous rigid frame generates, bearing is usually set at abutment pier position, but in recent years
Come with big city fast development, subway planning extends to city suburbs, and city focuses on Bridge Landscape, soft and graceful
Works favored by builder, flexible Thin-Wall Piers exactly meet this feature, simultaneously because subway overhead line road it is long, connection
Number is more, and structure need to meet the reasons such as linear deformation, and separated flexible Thin-Wall Piers are widely used.For example, No. 21 lines of Guangzhou Underground
Construction 19 mark, as the overhead section of clock use multi-joint continuous rigid frame, in order to meet the length travel under temperature action, abutment pier uses
Spacing minimum is only the separated flexible Thin-Wall Piers of 10cm, novel in design.So-called minimum spacing separate type Thin-Wall Piers refer to
Between two panels Thin-Wall Piers, the minimum spacing for being in center position is only about 10cm, also, from center between two panels Thin-Wall Piers
Distinguish V-shaped opening towards both sides at position.For this thin-walled pier structure, not mating construction mould in the prior art
Plate, meanwhile, because of its minimum spacing, the template of conventionally form can not accurately in place.Although can separately construct to two panels Thin-Wall Piers,
But such mode long construction period, progress are slow.
Invention content
The present invention is to provide a kind of minimum spacing separate type Thin-Wall Piers to avoid above-mentioned deficiency of the prior art
Construction method enables minimum spacing separate type Thin-Wall Piers to be able to smooth construction, and ensures construction quality.

Open end from formation " V " type;Two groups of " V " patterns plate is fixedly connected with the mutual socket joint in its hinged end between each other
And on the center line in Thin-Wall Piers, open end is open towards the two sides of Thin-Wall Piers;Separately there are two Side Templates and two side templates
It is interconnected to constitute outer frame template of the rectangle frame as Thin-Wall Piers, the open end pair of two Side Template and two groups of " V " pattern plates
The die cavity to form mutually independent two panels Thin-Wall Piers should be connected.
The design feature of the minimum spacing separate type Thin-Wall Piers template of the present invention is lain also in:In the opening of " V " the pattern plate
End is between two panels tablet punching block and is provided with support plate, shored using the support plate and obtained between two panels tablet steel plate
The openings of sizes of the open end of " V " pattern plate of setting.
The design feature of the minimum spacing separate type Thin-Wall Piers template of the present invention is lain also in:The adjustment structure of support plate is set,
Be in the open end of " V " the pattern plate, be in two panels tablet punching block between nut is fixedly installed, be equipped with the nut
Have bolt, the support plate be butted on the front end of the bolt, using the bolt adjustment support plate two panels tablet punching block it
Between the center line away from Thin-Wall Piers distance, so as to adjust the size of the opening.
The design feature of the minimum spacing separate type Thin-Wall Piers template of the present invention is lain also in:" V " the pattern plate is open at it
It is to be bolted between end and two Side Template.
The design feature of the minimum spacing separate type Thin-Wall Piers template of the present invention is lain also in:In the back rib of the tablet punching block
Weld the hanging plate for mounting cable wire so that can be pulled to " V " pattern plate by cable wire, " V " template is torn in implementation open
It removes.
The characteristics of construction method of the minimum spacing separate type Thin-Wall Piers of the present invention is:Minimum spacing separate type Thin-Wall Piers are set
Template, including two groups of " V " pattern plates, " V " the pattern plate are by two panels tablet punching block at one end between each other with hinge connection
The hinged end for forming " V ", the open end to form " V " type is separated from each other in the other end;Described two groups of " V " pattern plates are between each other
It is fixedly connected and is on the center line of Thin-Wall Piers with the mutual socket joint in its hinged end, open end is towards the both sides of Thin-Wall Piers
Side is open;Separately there are the outer frame template that two Side Templates and two side templates are interconnected to constitute rectangle frame as Thin-Wall Piers, the both ends
Template and the open end of two groups of " V " pattern plates are correspondingly connected with the die cavity to form mutually independent two panels Thin-Wall Piers;The construction party
Method carries out as follows:
Step 1, the reinforcing bar binding for completing separate type Thin-Wall Piers first, then install two groups of " V " pattern plates, accurate to adjust
The openings of sizes of " V " pattern plate;
Step 2 installs two Side Templates respectively at the both ends of " V " the pattern plate, two side templates is then fixedly mounted, two
Implement fastening between Side Template and two side templates, completes the installation of template, form the die cavity of mutually independent two panels Thin-Wall Piers;
The installation and concreting of step 3, often wheel template are carried out by the height of 3m, and thin for mutually independent two panels
The die cavity of wall pier is carried out at the same time concreting, the i.e. input health after completing concreting;
Step 4, in casting concrete after health reaches strength of mould stripping, remove successively two side templates, two Side Templates and
" V " pattern plate.
The characteristics of construction method of the minimum spacing separate type Thin-Wall Piers of the present invention, lies also in:For tearing open for two groups of " V " templates
Except being that direction respectively along respective " V " type opening is pulled.
Compared with the prior art, the present invention has the beneficial effect that:
