Description
Technical field
This utility model relates to the interior template of a kind of bridge variable cross-section thin-wall hollow high-pier, leads for bridge variable cross-section high pier construction
Territory.
Background technology
Increasingly use Materials with High Strength and thin-wall construction along with Longspan Bridge, the design of bridge variable cross-section tall pier and thin wall is by extensively
General employing.Bridge variable cross-section thin-wall hollow high-pier body has reasonable stress, saves the advantages such as material, and pier shaft design bottom is big, top
Little, set certain slope ratio (usually 80:1) along short transverse, its size gradually tapers up from bottom to top.But variable cross-section height pier
In work progress, the control difficulty of overall dimensions increases, the segmented pouring construction from bottom to top of high pier, and segment sizes is continually changing,
It is accomplished by configuring the template of multiple cross dimensions, or continuous for hypomere template cutting is used for epimere pours use, adapt to pier
Being continually changing of body size；Configuring the template of multiple cross dimensions, cause the input of template and consume greatly, cutting template is then
Need to expend more artificial, and cut size and be not easy to control, especially in mould, in the confined space closed, behaviour
Make difficulty bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of easy and simple to handle, safe and reliable, is suitable for the construction of variable cross-section thin-wall hollow high-pier
Adjustable internal-mold, it is possible to achieve the reusing of mould in Thin-walled Hollow Pier body, reduces input and the consumption of template, reduces
Construction cost also improves efficiency of construction.
For realizing the purpose of this utility model, it is provided that a kind of adjustable internal-mold plate for the construction of bridge variable cross-section hollow pier, including
4 pieces of side templates on four limits of template in composition, and it is positioned at 4 pieces of chamfering formworks at 4 angles of template, it is characterised in that: every piece
Side template includes that one piece of integral mold plate and two pieces of gang forms, every piece of gang form include that polylith is received seam and taken out block template, receive seam for one piece
Taking out block template and another block to receive seam and take out block template and be bolted, polylith is received seam and is taken out block template and connect the described combination die of composition according to this
Plate；The both sides of one piece of integral mold plate are taken out block template respectively and are bolted one piece of side of composition with a gang form outermost receipts seam
Template；Every piece of described chamfering formwork includes Angle formwork, Angle formwork be respectively provided on two sides with flank, shape between described flank and Angle formwork
Become the angle of 135 °, two flanks of described Angle formwork overlap joint overlapping with the side template closed on respectively.
This utility model is provided with parting in interior template and takes out block template, takes out block template and regulation chamfering mould by mode division seam in increase and decrease
Plate and parting take out block template overlapping widths to realize being continually changing of pier shaft sectional dimension, have easy and simple to handle, controllability is strong
Advantage, reduces the difficulty of mould change in size in variable cross-section thin-wall hollow high-pier, improves pier shaft overall dimensions control accuracy, real
Show the recycling of template, reduced template and put into and consume, and improve efficiency of construction.

Detailed description of the invention
As it is shown in figure 1, a kind of adjustable internal-mold plate for the construction of bridge variable cross-section hollow pier provided by the utility model, bag
Include 4 pieces of side templates 1 on interior four limits of template of composition, and be positioned at 4 pieces of chamfering formworks 2 at 4 angles of template；
As in figure 2 it is shown, every piece of side template 1 includes one piece of integral mold plate 3 and two pieces of gang forms 4；
As shown in Fig. 3, Fig. 4, Fig. 5, every piece of gang form 4 includes that polylith is received seam and taken out block template 5, receives seam for one piece and takes out block mould
Plate 5 is taken out block template with another block receipts seam and is connected by bolt 6, and polylith receipts seam is taken out block template 5 and connected the described combination die of composition according to this
Plate 4；
Pass through as in figure 2 it is shown, block template 5 is taken out with a gang form 4 outermost receipts seam respectively in the both sides of one piece of integral mold plate 3
Bolt 6 connects one piece of side template of composition；
As shown in Figure 6, every piece of described chamfering formwork 2 includes Angle formwork 7, Angle formwork 7 be respectively provided on two sides with flank 8, institute
State the angle forming 135 ° between flank 8 and Angle formwork 7.
During installation, by two flanks of described chamfering formwork overlap joint overlapping with the side template closed on respectively, as shown in fig. 1.
As a kind of specific embodiment, as shown in Fig. 3, Fig. 5, every piece receive that seam takes out block template 5 be respectively provided on two sides with angle steel system
The perpendicular rib 9 made, two pieces of adjacent receipts seams are taken out and are connected by perpendicular rib 9 bolt 6 between block template 5.
When this utility model is embodied as, the width of flank can be set greater than one piece receive seam take out block template width two/
One, it is simple to by the overlapping lap width of regulation flank with side template, it is achieved interior template size shrinks.
As a kind of specific embodiment, the width that every piece of receipts seam takes out block template can be set to by this utility model in use
150mm；The flank width of described chamfering formwork is set greater than 75mm.
When using above-mentioned adjustable internal-mold plate provided by the utility model to carry out the construction of bridge variable cross-section hollow pier, pier stud external mold
Using hydraulic climbing slding form operation, interior mould uses overmolded mode to construct.Interior template construction can use following methods:
According to the design size of first segment pier stud, take out the quantity of block template, by first by the seam of receiving of every piece of side template both sides of increase and decrease
In joint, the width adjustment of every piece of side template of template is to appropriate size, then every piece of chamfering formwork of template and side in installation first segment
Template, keeps both sides one fixed width overlapping with the flank of adjacent chamfering formwork, the installation respectively of every piece of side template during installation
After-pouring first segment pier stud concrete；Template in each joint up from second section, first according to the slope ratio of pier stud, meter before installing
Calculating interior template should be to the size of contract, and can then see by increasing the both sides of every piece of side template and adjacent chamfering formwork
The width of flank lap reaches the contraction size of requirement, if can reach, then installs according to the mounting means of template in first segment,
And when mounted the both sides of every piece of side template are adjusted to proper width with the flank lap of adjacent chamfering formwork；If can not
Reach, then the seam of receiving reducing side template both sides takes out the quantity of block template, then according to the mounting means of template is installed in first segment,
And pour this joint concrete.So circulate construction, until whole pier stud has poured.
