Concrete dam transverse joint rubber water-proof climbing device
Technical field:
The utility model relates to a kind of installation of putting transverse joint rubber water-proof when being applicable to all kinds dam concrete and building and lay operation, the concrete dam transverse joint rubber water-proof climbing device of transverse joint rubber water-proof installation exercise while being particularly useful for gravity concrete dam, dome dam concreting.
Background technology:
Although the situation of being critically ill appears in dam, many reasons is arranged, with regard to most of situation, hydraulic structure sealing imperfection and cause the storehouse seepage, thus cause that breaking down is one of major reason wherein.Therefore, hydraulic structure being strengthened to waterstop construction process targetedly inspects for acceptance just especially important.Usually operated by rotary motion rubber fastening band and copper waterstop twice sealing in the dam transverse joint.In work progress, waterstop must be reliable fixing, avoids being subjected to displacement when fluid concrete, guarantees the tram of waterstop in concrete.Due to the length long (monovolume length is 20m usually) of waterstop, weight, also than weight, adopts a dead lift to waste time and energy in carrying out storehouse face uphill process simultaneously.
The utility model content:
The purpose of this utility model is to be fixed on the template lifting operation platform in order to provide a kind of, lifting with the dam template is climbed, guarantee that the laying of sealing in the face uphill process of storehouse is convenient, save time, laborsaving, safe and efficient, in carrying out the dam concrete casting process, can be shifted and fix, make sealing install easier contraposition, centering the rubber water-proof climbing device.
The purpose of this utility model is achieved like this:
The utility model concrete dam transverse joint rubber water-proof climbing device, comprise bearing, be positioned at the cylinder between bearing, cylinder is contained on bearing and can rotates by the back shaft at its two ends, by bolt and nut component, the detachable band iron that termination, rubber fastening band upper end is compressed is housed vertically on cylinder.
On above-mentioned back shaft, be equipped with on back-up ring, termination latch is housed with the roller bearing adjacent.
In carrying out the standby storehouse of concrete and concreting process, fixedly the position of waterstop just makes it not to be subjected to displacement and must the upper and lower termination of waterstop be fixed by " two one lines " principle.Termination, waterstop bottom has been embedded in concreting, the utility model rubber water-proof climbing device is born the pinned task of waterstop upper end, problem that solution is adopted manually and promoted in carrying out storehouse face uphill process, the layout waterstop is wasted time and energy, the utility model is fixed on the template lifting operation platform, along with the laying of waterstop is carried out in the lifting of standby storehouse process template automatically.The utility model adopts the form of cylinder well to solve the laying problem of sealing in the face uphill process of storehouse.
The utility model rubber water-proof climbing device processing and fabricating is simple, processes by steel pipe, reinforcing bar and shaped steel, and the installation and maintenance cost is low, only approximately 400 yuan of its single costs of manufacture.And after adopting the rubber water-proof climbing device, installation waterstop labor hour can be saved approximately 2 hours in single storehouse, 12 yuan/storehouse is equivalent to reduce expenses.
The utility model is saved the standby storehouse time of concrete, saved cost of labor make the laying of waterstop convenient, save time, laborsaving, safe and efficient, guaranteed the tram of rubber fastening band in concrete, improved waterstop laying construction quality.
The accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the present embodiment concrete dam transverse joint rubber water-proof climbing device, comprise bearing 1, be positioned at the cylinder 2 of bearing.Cylinder is contained on bearing and can rotates by the back shaft 3 at its two ends.On cylinder, by bolt and nut component 4, the detachable band iron 5 that termination, rubber fastening band upper end is compressed is housed vertically.Back-up ring 6 is housed on back shaft, latch 7 is housed on its termination.The rack platform height is 1000mm, and diameter of cylinder is 600mm, and the cylinder support shaft diameter is 150mm.
Drum spindle is by steel pipe machine-shaping, and cylinder both sides back-up ring is processed by round steel, and bearing is formed by the channel-section steel processing and fabricating.
The utility model can directly carry out the processing and fabricating of sealing climbing device in comprehensive process factory.Field by using mobile crane or storehouse face auxiliary hoisting device lift, and sealing climbing device bracing frame can adopt iron wire and template operation platform to be fixed.
The utility model sealing climbing device fabrication and installation method
1, the sealing climbing device is at comprehensive process factory processing and fabricating, and material is common steel tube, reinforcing bar and shaped steel, uses welding rod to be the E43 type, continuous full weld, weld bead height 6mm; Quality of materials should meet drawing and related standard requirements; Width and the size of cylinder can be set flexibly according to the different model of waterstop;
2, the sealing climbing device, for the fixing and installation of the conventional plastics waterstop of concrete dam transverse joint, first is arranged on the rubber fastening band of rolling in sealing climbing device cylinder in storehouse, and termination is fixed by the detachable band iron on cylinder; Then by mobile crane or storehouse face auxiliary hoisting device, the operating platform that the sealing climbing device winches to transverse joint place template is fixed.
3, the sealing climbing device can carry out the fixing concrete pouring construction that reaches of sealing in storehouse after being fixed on transverse joint template lifting operation platform, when concreting completes while carrying out concrete standby storehouse, next storehouse, the lifting process that directly carries out template is namely the process that waterstop rises and lays; Start to enter next storehouse concrete construction circulation, until a volume waterstop has been laid.
