Utility model content
The utility model is the weak point for avoiding existing for above-mentioned prior art, a kind of superelevation abnormity water conservancy project structure corner template be applied in water conservancy project structure construction is provided, to reduce difficulty of construction, makes construction quality be convenient to control, reduce material input cost, reach designing requirement.
The utility model is that technical solution problem adopts following technical scheme:
The feature of the utility model superelevation abnormity water conservancy project structure corner formwork support structure is: on the concrete-pool-wall of described water conservancy project structure, be positioned at corner position place and arrange pre-doweling, and have split bolt and described joint bar to be fixedly connected; Corner form surfacing arcuately stands upright on corner position, and its arch surface is towards corner side; In the outside of described corner form surfacing, vertically interval arranges each road sizing cage of reinforcement in level; Fixing described each road by the upright outer stupefied series connection of vertical two steel pipe shapes between cage of reinforcement; Described vertical pair of steel pipe outer stupefied by described split bolt with utilize butterfly to block to the form of drawing and nut fastening.
The feature of the utility model superelevation abnormity water conservancy project structure corner formwork support structure is also:
Described corner form surfacing adopts the iron sheet of 3mm, and described sizing cage of reinforcement is formed by the reinforcement welding of Ф 16, and the spacing between neighbouring twice sizing cage of reinforcement is 500mm.
Described vertical pair of steel pipe is stupefied is outward at least spaced twice.
Each road vertical reinforcement back cord is arranged at intervals with in described form surfacing, along arcuate edge.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model utilizes pre-doweling to carry out formwork reinforcement, firmly reliable;
2, in the utility model, corner form surfacing adopts the iron sheet that 3mm is thick, replaces traditional wooden model or sizing punching block, significantly reduce difficulty of construction and cost with this, and make construction quality be convenient to control, Yi Tian reaches the corner arc of designing requirement, improves workmanship.
Accompanying drawing explanation
Fig. 1 is corner formwork support structure plan view in the utility model;
Fig. 2 is corner formwork support structure elevation in the utility model;
Number in the figure: 1 corner concrete, 2 concrete-pool-walls, 3 form surfacings, 4 vertical reinforcement back cords, 5 sizing cage of reinforcement, 6 split bolts, 7 vertical two steel pipes are outer stupefied, 8 pre-dowelings.
Detailed description of the invention
See Fig. 1 and Fig. 2, in the present embodiment, the form of superelevation abnormity water conservancy project structure corner formwork support structure is: on the concrete-pool-wall 2 of water conservancy project structure, be positioned at corner position place and arrange pre-doweling 8, and have split bolt 6 and joint bar 8 to be fixedly connected; Corner form surfacing 3 arcuately stands upright on corner position, and its arch surface is towards corner side; In the outside of corner form surfacing 3, vertically interval arranges each road sizing cage of reinforcement 5 in level; Shape between cage of reinforcement 5 by the outer stupefied 7 fixing described each roads of series connection of upright vertical two steel pipe; Vertical two steel pipe outer stupefied 7 by split bolt 6 with utilize butterfly to block to the form of drawing and nut fastening, the outside of corner form surfacing 3 is concave surface side of corner form surfacing 3.
In the present embodiment, corner form surfacing 3 adopts the iron sheet of 3mm, and sizing cage of reinforcement 5 is formed by the reinforcement welding of Ф 16, and the spacing between neighbouring twice sizing cage of reinforcement 5 is 500mm; In order to ensure that Stability Analysis of Structures is firm, vertical two steel pipe outer stupefied 7 is at least spaced twice, in order to increase the hardness of form surfacing 3, in form surfacing, is arranged at intervals with each road vertical reinforcement back cord 4 along arcuate edge.
In the present embodiment, the construction method of superelevation abnormity water conservancy project structure corner formwork support structure is carried out as follows:
Step 1: by corner form surfacing 3 and sizing cage of reinforcement 5, and vertical two steel pipe outer stupefied 7 welds, and completes the processing of corner template.
Step 2: the concrete-pool-wall 2 of building water conservancy project structure, and pre-doweling 8 is arranged in the concrete-pool-wall 2 of water conservancy project structure, complete the maintenance of the concrete-pool-wall 2 of water conservancy project structure.
Step 3: after the maintenance of concrete-pool-wall 2 completing water conservancy project structure, removes the concrete sump wall form of water conservancy project structure, is fixedly welded by split bolt 6 with pre-doweling 8.
Step 4, the corner template of step 1 being processed is placed on the corner position of setting, and employing split bolt 6 is blocked by butterfly on the vertical two steel pipe outer stupefied 7 in each road and nut carries out, to drawing and fixing, completing the support of corner template.
Step 5: build corner concrete 1, after completing the concrete maintenance of corner, removes corner template and namely completes construction.
Corner radius in the present embodiment is 2m, and corner height is 8m, and pre-doweling 8 is the grade III steel muscle of Ф 14, and split bolt 6 is diameters is 14mm high strength split bolt, and split bolt 6 and pre-doweling 8 adopt single-selded lap joint, and weld length is 150mm; Vertical back cord 4 adopts Ф 16 reinforcing bar, and between adjacent vertical reinforcement back cord 4, spacing is 100mm, and vertical two steel pipe outer stupefied 7 is the two steel pipe two groups of 48*3mm.
