Abstract
A process for installing and detaching the combined steel shutterings of bridge pier is characterized by that the semi-circular steel shuttering is combined on the ground and then lifted and fixed, the bridge pier is then cast with concrete, and the steel shuttering is finally detached and lifted onto ground. Its advantages are high construction speed and high appearance quality.
Description
(1) technical field:
The present invention relates to a kind of process in bridge engineering field, belong to process for installing and detaching combined steel shutterings of bridge pier.
(2) background technology:
Bridge pier column is an important step in the bridge construction, and bridge pier column construction at present is manually to set up well word scaffold (reinforcing cage) mostly, manually a section splicing from lower to upper of semicircle template is installed then; Pier stud build finish after, again with semicircle template a section from top to bottom the dismounting.Construction speed is slow, a large amount of labor intensive, furthermore owing in the template reinforcing cage is arranged, can't polish in the template interface place, thereby make the reinforced concrete post surface of building out that the template interface vestige be arranged, and influences presentation quality.
(3) summary of the invention:
Technical problem to be solved by this invention is the problem of the slow and labor intensive of bridge pier column construction speed.
Adoptable technical scheme is: this process for installing and detaching combined steel shutterings of bridge pier, comprise combined steel formwork, carry out according to following steps, a. docks each semicircle combined steel formwork according to the pier stud design height on the ground, is combined into Overall Steel Formwork with bolt; B. the step of Overall Steel Formwork interface is tied; C. use crane that above-mentioned Overall Steel Formwork is sling, fixed; D water cement concrete pouring pier stud; E. the people opens the bolt that is connected and fixed with Overall Steel Formwork from top to down from the semicircle interface and forms the semicircle steel form of two monoblocks on the workbench that crane is sling; F. hang out the semicircle steel form of two monoblocks at twice with crane, then again with the synthetic Overall Steel Formwork of the semicircle template group of two monoblocks; When g. carrying out the construction of next bridge pier column, repeat above-mentioned b～f and get final product.
Therefore this beneficial effect of the invention is: since the steel form of this process using be on ground to being connected into Overall Steel Formwork, reduced manpower and expended; Moreover steel form once lifts fixing, and construction speed is fast, moreover the two whole semicircle steel forms that unload need not be fixing to each steel form butt joint, and only need get final product accelerating construction progress to the butt joint of two halves circular steel template; And behind the butt joint steel form, interface is tied, guaranteed construction back presentation quality.

Fig. 1 is the front view of the present invention when installing;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the front view that the present invention tears when back open;
Fig. 4 is the left view of Fig. 3.
The 1-bolt, the 2-combined steel formwork.
(5) specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing:
This process for installing and detaching combined steel shutterings of bridge pier comprises combined steel formwork 2, carries out according to following steps:
A. as shown in Figure 1, according to the pier stud design height each semicircle combined steel formwork 2 is docked on the ground, become Overall Steel Formwork (seeing shown in the accompanying drawing 2) with bolt 1 fixed combination, avoid manually a section splicing from lower to upper of semicircle template being installed while constructing, reduced labour cost, time saving and energy saving.
B. Overall Steel Formwork is tied the step of interface with the hand grinding tool machine; There is the template interface vestige on the reinforced concrete post surface of avoiding building out and influences presentation quality.
C. use crane that above-mentioned Overall Steel Formwork is sling, fixed; A large amount of manpower splicing steel forms have been saved in once success, and progress is fast.
D. water cement concrete pouring pier stud waits to reach certain intensity.
E. the people opens the bolt (seeing shown in the accompanying drawing 3) that is connected and fixed with Overall Steel Formwork from top to down from the semicircle interface and forms the semicircle steel form (seeing shown in the accompanying drawing 4) of two monoblocks on the workbench that crane is sling; Saved manpower greatly, construction speed is also accelerated greatly, and construction quality reaches assurance.
F. hang out the semicircle steel form of two monoblocks at twice with crane and be placed on underground, then again with the synthetic Overall Steel Formwork of the semicircle template group of two monoblocks shown in the accompanying drawing 4, do not need each steel form butt joint fixing, accelerating construction progress.
G. when carrying out the construction of next bridge pier column, as long as repeat above-mentioned b～f.
The progress of as seen this bridge pier column construction is that people like soon, has saved manpower greatly, and construction speed and quality also improve greatly, suitable promoting the use of.
