Wherein, Fig. 2 double as Figure of abstract.
Among the figure: 1, panel, 2, web member, 3, working platform, 4, anchor cone, 5, dowel, 6, interior chord member, 7, outer chord member, 8, regulate bearing, 9, connecting bolt, 10, front beam, 11, front-slider, 12, rear cross beam, 13, vertical adjusting rod, 14, rear slider, 15, the wedge slotted eye, 16, the drift groove, 17, location-plate, 18, levelling lever, 19, wedge.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, panel 1 of the present utility model is a steel plate, and every panel 1 back side is fixed together with bolt and web member 2.Web member 2 is to form with channel-section steel and angle steel processing and fabricating, interior chord member 6 upper ends are provided with wedge slotted eye 15, the lower end is provided with location-plate 17, location-plate 17 is provided with drift groove 16, on, chord member 6 is by wedge slotted eye 15 in the lower template, drift is connected with location-plate 17, in the overlapping slotted eye of drift groove 16 on drift wedging wedge slotted eye 15 and the location-plate 17, so both can bear, the pulling force that the interior chord member of lower bolster is 6, also can bear horizontal thrust, the setting of drift groove 16 simultaneously also makes, chord member 4 spacings have adjustability in the lower template, still can guarantee not intermittently construction continuously in the time of can making the concrete vertical plane turnover occur.When the utility model was installed, the vertical adjusting rod 13 of outer chord member 7 usefulness of upper and lower layer template web member 2 connected, and regulates the template gradient by regulating vertical adjusting rod 13, makes it to adhere to specification.
When deep camber hyperbolic rolled concrete arch dam is constructed, be one group with three templates of vertical pile, in concreting process, alternately rise.Whenever build when rising layer to one, need realize the adjustment of the identical or different horizontal curvature in the upper and lower limit of template by regulating adjusting bearing 8 and the levelling lever 18 in the level(l)ing device; By the adjusting of front-slider 11 in the vertical adjusting device and rear slider 14, adjust the angle of single form swing and the relative position between the vertical gang mould, so just can make template adapt to the requirement that arc dam constantly changes.When level two adjacent templates can not connect by bolt, need adopt the piece plate or transfer the seam plate to squeegee.
During concreting with anchor cone 4 one ends with imbed in the concrete after dowel 5 is connected, anchor cone 4 is imbedded the part outsourcing plastic sheath in the concrete, is convenient to remove turnover and uses, the other end is fixed template by the dowel beam.Every template is arranged 1 row's dowel 5, and working load is born by dowel all the time during construction, and dowel 5 is designed to the ring-type swallow-tail form, can improve the bond stress between dowel and the roller compacted concrete like this.When concrete casting to distance went up piece template top 30-60 centimetre high most, this moment, concrete lateral pressure was born by this layer template dowel 5, will descend the piece formwork hoisting going up most on the piece template then most, so repeatedly, reached the purpose that continuous concreting is risen.
Hang excessive position by the feet in dam bottom or top, adopt one group of truss to join two groups of ring-type swallow-tail form dowels, can improve the bearing capacity of dowel effectively, can use safely at any position of hanging by the feet.
The utility model river hydroelectric pivotal project of soliciting in Hubei is able to successful Application, carrying out continuously of concrete pouring construction appears also having guaranteed when deep camber changes at concrete surface, build the dam body surface aesthetic, the two-way adjustable formwork of 1 cover is removed and is installed, and just can finish in 5-7 minute.Facts have proved, the utlity model has easy and simple to handle fast, safe in utilization, guarantee the advantage of construction quality.
