Single positive outrigger template 201 arranges vault towards front arcuate ribs 25, and combines longitudinal floor 24 and be matched with template main frame, and its technique effect is as follows:
One is the comprcssive strength towards front that the existence of longitudinal floor 24 and arcuate ribs 25 adds the template main frame of single positive outrigger template 201.
Two when being assemble plastic building template in construction, also needs the form bracing system formed with special formwork-support and corresponding auxiliary part plastic building template is supported and fixes simultaneously.In the present embodiment, the trailing flank of left support foot 23-1 and right support foot 23-2 is directly supported by formwork-support.The existence of formwork-support so that act on the pressure on the leading flank of front side transverse slat 21-1 during casting concrete and be all transformed into the elastic deformation of single positive outrigger template 201.
In the middle of the left back end of the left part of arcuate ribs 25, left side, shaped as frame position 201c and left support foot 23-1 is sequentially connected along the bending direction of the left part of arcuate ribs 25, in the middle of the right rear end of the right part of arcuate ribs 25, right side, shaped as frame position 201d and right support foot 23-2 is then sequentially connected along the bending direction of the right part of arcuate ribs 25, thus defining the supporting system of the domes of single positive outrigger template 201.
When casting concrete, the active force being applied on the leading flank of front side transverse slat 21-1 mainly has 2 kinds, a kind of lateral pressure being because concrete gravity and produce, another kind is the vibration force smashing the relatively large cyclic produced when stirring concrete at immersion vibrator (also known as vibrating head or concrete vibration bar).After both active forces are applied on the leading flank of front side transverse slat 21-1, owing to the elastic modelling quantity of left side supporting system and right side supporting system is very big, the elastic deformation making single positive outrigger template 201 occur mainly in the left and right of front side transverse slat 21-1, arcuate ribs 25 and middle transverse slat 21-2 to position, middle part, making them upwards produce elastic deformation in front and back, the effect particularly in moment produced when smashing pouring concrete bigger vibration force is lower and the bigger sagittal elastic deformation that produces.Two kinds of described active forces also make other corresponding site including the first swash plate 26-1 and the second swash plate 26-2 also all have corresponding less elastic deformation.Due to domes supporting system elastic modelling quantity in forward direction relatively big (this elastic modelling quantity is still less than the elastic modelling quantity of left side supporting system and right side supporting system), thus the pressure vibrated is once reduce, then can recover rapidly under the elastic reaction of domes supporting system to corresponding state, so that the left and right of single positive outrigger template 201 to the position, middle part elastic modelling quantity in forward direction bigger, there is the characteristic recovered rapidly when external force reduces or disappears, namely smash stir concrete time single positive outrigger template 201 there is good deformation resistance.
