A kind of asphaltic concrete core wall adjustable formwork device
Technical field
A kind of asphaltic concrete core wall adjustable formwork of the utility model device is used for the asphaltic concrete core wall construction.
Background technology
In the earth and rockfill dam asphaltic concrete core wall engineering, the transition of asphaltic concrete core wall and both sides (sandstone material) needs the synchronous layered rising that paves, rolls.For satisfying being connected of adjacent two templates with the core-wall axis direction of asphaltic concrete core wall change in size in height, the core-wall template is required can fix reliably, guarantee core-wall cross dimensions and installation and removal fast.
Summary of the invention
Needs at asphaltic concrete core wall template Fast Installation and dismounting.The utility model provides a kind of asphaltic concrete core wall adjustable formwork device, and this device is suitable for the asphaltic concrete core wall of different section size, easy to operate, cost is low, can Fast Installation and dismounting.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: a kind of asphaltic concrete core wall adjustable formwork device, comprise template, template is provided with fixing card, fixedly links and is connected to adjustable joint steel pipe, can regulate steel pipe and by bolt connecting rod is installed.
Described connecting rod two ends all with can regulate steel pipe and be connected, and by bolt, realize regulating steel pipe flexible and fixing in connecting rod by bolt.
Described fixedly card with can regulate steel pipe welding, before the bolton, by adjusting adjustment and the location that the relative position that can regulate steel pipe and connecting rod is realized template, tight a bolt, realize fixing to template.
Described template is steel plate, length: 1.8 ~ 2.0m, highly: 250 ~ 350mm, thickness 10 ~ 14 mm.
The described diameter of bolt 12 ~ 14 mm, described connecting rod, can to regulate steel pipe be common steel tube, and described connecting rod is provided with two borings, and the internal diameter of described connecting rod is greater than the external diameter that can regulate steel pipe.
A kind of asphaltic concrete core wall adjustable formwork of the utility model device, template is with fixing card and can regulate the steel pipe welding, guarantees to fix card and can regulate steel pipe to form a fixing integral body.The connecting rod two ends all with can regulate steel pipe and be connected, fix by prepared screw-bolt hole, adjustment can be regulated steel pipe and insert the length that the length of connecting rod is regulated whole fixing templates, makes it satisfy asphaltic concrete core wall change in size and the realization support of template and being connected of adjacent two templates.The utility model can effectively be guaranteed the stability of asphaltic concrete core wall template, has reduced the workload when template is installed and removed, and this device can use repeatedly.
Description of drawings
Fig. 1 is the utility model apparatus structure schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of asphaltic concrete core wall adjustable formwork device comprises template 5, and template 5 is provided with fixing card 1, and fixing card 1 is connected with can regulate steel pipe 4, can regulate steel pipe 4 and be installed with connecting rod 3 by bolt 2.Described connecting rod 3 two ends all with can regulate steel pipe 4 and be connected, and fixing by bolt 2, by bolt 2 realize regulating steel pipe 4 connecting rod 3 in flexible with fix.Adjustment can be regulated the length that steel pipe 4 inserts connecting rod 3, and the length of regulating whole adjustable formwork device makes it satisfy asphaltic concrete core wall change in size and the realization support of template and being connected of adjacent two templates.
Described fixedly card 1 with can regulate steel pipe 4 welding, before bolt 2 is fastening, by adjusting adjustment and the location that the relative position that can regulate steel pipe 4 and connecting rod 3 is realized template 5, tight a bolt 2, realize fixing to template 5.
Described template 5 is steel plate, length: 1.8 ~ 2.0m, highly: 250 ~ 350mm.Described fixedly card is special mould clamp, and the diameter of bolt 12 ~ 14 mm, can regulate steel pipe 4 and are common steel tube described connecting rod 3, and described connecting rod 3 is provided with two borings, and the internal diameter of described connecting rod 3 is greater than the external diameter that can regulate steel pipe 4.
Implementation step:
During installation, fixing card 1 and can regulate steel pipe 4 and weld can be regulated steel pipe 4 and be connected with connecting rod 3, before bolt 2 is fastening, by adjustment can regulate steel pipe 4 with the relative position of connecting rod 3, accurate adjustment and the location of realizing template 5.After adjustment is finished, by tighting a bolt 2, can realize the fixing of template 5.
During dismounting, unclamp bolt 2, directly mention connecting rod 3, can mention whole fixing templates, and then stripping 5, if follow-up construction part template spacing is constant, need not to adjust and can directly use fastening devices.
