Description
Technical field
It is to be related to a kind of flexible pier horizontal subdivision to break specifically the present invention relates to Bridge Construction technical field
The construction method and its constructing device of seam.
Background technology
With continuing to develop for China's economy, for the requirement also more and more higher of Urban Bridge Construction quality, and to bridge
Landscape requirement also more and more higher so that bridge turns into a line of scenery in city, even as city
Business card.
At present, most bridge is multispan bridge, and the two ends of general multispan bridge can set the larger abutment of rigidity,
And middle pier is then disposed as flexible pier so that when bridge pier is when by pier top thrust, can be in the scope of safety
It is interior that larger horizontal displacement occurs, and ensure on the direction along bridge, the horizontal connection between the bridge pier of bridge by completely every
It is disconnected so that each bridge pier individually bears brake force or the tractive force transmitted on bridge.Further, since the horizontal thrust of bridge pier is by each
The rigidity distribution of pier so that be assigned to the horizontal thrust very little on each bridge pier, the security that protection bridge is used.
However, the landscape in order to ensure bridge, typically can set ornamental blocks, to play dress to bridge in the outside of bridge pier
Decorations act on, and in order that ornamental blocks can normally using, it is necessary to ensure that ornamental blocks are not involved in the overall stress of bridge pier.But,
Because bridge pier can occur larger horizontal displacement when by horizontal thrust, often cause that ornamental blocks can more or less be subject to bridge pier
On horizontal thrust involve, cause the damage of ornamental blocks, there is potential safety hazard.
And way conventional at present is to cut out horizontal joint in the ornamental blocks of shaping, to reduce what ornamental blocks were subject to as far as possible
Horizontal thrust on bridge pier, but, it is big, into seam to there is depth as shallow, cutting difficulty in the horizontal joint that the form of construction work cuts out
Size and effect cannot ensure, construction safety risk high and the problems such as high cost.Further, since the horizontal joint for cutting out
Depth as shallow so that ornamental blocks still can be subject to the horizontal thrust on bridge pier, cause ornamental blocks to be easily damaged, and there is potential safety hazard.
The content of the invention
In order to solve the above problems, the main object of the present invention is to provide a kind of simple to operate, big, smart into seam into seam depth
Degree height and the construction method into the seam measured flexible pier horizontal subdivision breaking joint of matter.

As a example by layer pumping board 20, the first rigid foam plate 30, the first edge sealing pumping board 40, the first top layer pumping board 50 and the first film material 60
Die-filling step to the construction method is illustrated.
Specifically, the construction method includes：Pre-treatment step：
The top surface of the bridge pier elementary section 91 to having poured is cleared up so that the top surface of the bridge pier elementary section 91 that this has been poured can
With the adhesive force between concrete to be poured, quality of connection between bridge pier elementary section is improved, and then improve the construction matter of bridge pier
Amount, it is ensured that the security that bridge pier is used in the later stage.Additionally, pre-buried on the top surface of the bridge pier elementary section 91 for having poured after the cleaning
The reinforcing bar of bridge pier elementary section to be poured, ensures that bridge pier elementary section to be poured has after formation enough strong by embedded bar
Degree.
Die-filling step：
First, the first bottom is respectively mounted to the relative both sides of X along bridge on the top surface of the bridge pier elementary section 91 for having poured to take out
Plate 20, the second bottom pumping board 200.

Second edge sealing pumping board 400 and the second top layer pumping board 500 when the concreting of new one section of bridge pier elementary section is carried out, by concrete
Extruding and shift.
Then, the second supporting template 8 is installed along the circumferential profile of the top surface of the bridge pier elementary section 91 for having poured, and formation is treated
Pour cavity 93.
Additionally, completing the first bottom pumping board 20, the first edge sealing pumping board 40, the first top layer pumping board 50, the second bottom pumping board
200th, after the installation of the second edge sealing pumping board 400, the second top layer pumping board 500 and the second supporting template 8, each pumping board and second are supported
The installation site of template 8 checked and corrected, and prevents the position of each pumping board and the second supporting template 8 from larger error occur, is kept away
Exempt from influence horizontal subdivision breaking joint into seam size, into seam precision and into seam quality.
Pour and curing step：
As shown in fig. 6, carry out concreting to cavity to be poured 93, and to pouring after concrete conserve, form new
Bridge pier elementary section.
Demoulding step：
As shown in Figure 7 and Figure 8, first, after the completion of concrete curing, release the first bottom pumping board 20, the first edge sealing pumping board 40,
First top layer pumping board 50 is fixedly connected with the first supporting template 7；Similarly, the second bottom pumping board 200, the second edge sealing is released to take out
Plate 400, the second top layer pumping board 500 are fixedly connected with the first supporting template 7.
