Abstract
The utility model discloses a kind of un-bonded prestressed steel strand Special hole mold, comprise the cave mould main body of tubulose, be sealed on the top board of cave mould main body upper orifice and be sealed on the base plate of cave mould main body lower nozzle; The center of top board is provided with the perforation of end face steel strand; The center of base plate is provided with bottom surface steel strand perforation; Top board is fixed with semi-circular handle.This Special hole mold makes simple, with low cost, installs location conveniently, without the need to manually installing template separately, saving labor and materials machine, the reduction of erection time, having application prospect preferably.
Description
Technical field
The utility model relates to a kind of prestress engineering construction tool, especially a kind of steel strand Special hole mold.
Background technology
At present, at the construction field (site) in work progress, in prestress wire construction, Cast-in-situ Beam, plate top surface stretching end cave mould adopt foam cave mould, wooden form, plastic formwork etc. usually.Wherein, wooden form, plastic formwork all need manually to carry out installing template, carry out template perforate.And when removing these templates, time cave mould is generally removed, all can be removed damage, can not continue to re-use.Although the cave mould of foam is cheap, concrete Forming Quality can not get effective control, and needs manually to be rejected by cystosepiment, and easily cause on-the-spot material contamination during dismounting, do not reach the target of energy-conserving and environment-protective, labor intensive is larger.
Use above-mentioned material as cave mould, consume ample resources, and can not use be had enough to meet the need, not only increase engineering cost, more cause the unnecessary wasting of resources, not energy-conservation, not environmentally.
Utility model content
Utility model object: solve existing cave mould and not only increase engineering cost, and waste resource, not energy-conservation, not environmentally.
Technical scheme: un-bonded prestressed steel strand Special hole mold described in the utility model, comprises the cave mould main body of tubulose, is sealed on the top board of cave mould main body upper orifice and is sealed on the base plate of cave mould main body lower nozzle; The center of top board is provided with the perforation of end face steel strand; The center of base plate is provided with bottom surface steel strand perforation; Top board is fixed with semi-circular handle.
Adopt the cave mould main body of tubulose to carry out supports formation one to concrete to shape space, and can extract and reuse; Adopting the perforation of end face steel strand and bottom surface steel strand to bore a hole is conducive at steel strand pre-buried in concrete after curved arrangement, can pass through mould sizing space, cave and extend to expose to be arranged in concrete surface; Adopt semi-circular handle cave mould can be facilitated to rotate and propose.
As further restriction scheme of the present utility model, the diameter of end face steel strand perforation is greater than the diameter of bottom surface steel strand perforation.The diameter that end face steel strand are bored a hole is set to be greater than the diameter of bottom surface steel strand perforation, can to penetrate after in the steel strand perforation of bottom surface at steel strand can also smoothly and pass rapidly.
Compared with prior art, its beneficial effect is the utility model: (1) adopts the cave mould main body of tubulose to carry out supports formation one to concrete and to shape space, and can extract and reuse; (2) adopting the perforation of end face steel strand and bottom surface steel strand to bore a hole is conducive at steel strand pre-buried in concrete after curved arrangement, can pass through mould sizing space, cave and extend to expose to be arranged in concrete surface; (3) semi-circular handle is adopted cave mould can be facilitated to rotate and propose.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state view of the present utility model.
In figure: 1, cave mould main body, 2, base plate, 3, top board, 4, the perforation of end face steel strand, 5, the perforation of bottom surface steel strand, 6, semi-circular handle, 7, steel strand, 8, concrete.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
Embodiment 1:
As illustrated in fig. 1 and 2, un-bonded prestressed steel strand Special hole mold of the present utility model comprises: the cave mould main body 1 of tubulose, be sealed on the top board 3 of cave mould main body 1 upper orifice and be sealed on the base plate 2 of cave mould main body 1 lower nozzle.
Wherein, end face steel strand perforation 4 is provided with in the center of top board 3; Bottom surface steel strand perforation 5 is provided with in the center of base plate 2; Top board 3 is fixed with semi-circular handle 6; The diameter of end face steel strand perforation 4 is greater than the diameter of bottom surface steel strand perforation 5.
When specifically making, cave mould main body 1 adopts diameter 160mm steel pipe manufacturing, and top board 3 and base plate 2 are welded on the upper lower nozzle of cave mould main body 1, forms a sizing space; The diameter of bottom surface steel strand perforation 5 is 22mm, and the diameter of end face steel strand perforation 4 is 30mm, is conducive at steel strand 7 pre-buried in concrete after curved arrangement, and the setting space that can pass through cave mould also extends exposes the surface being arranged in concrete eight.
When constructing at the scene, before concrete eight is built, cave of the present utility model mould is coordinated and utilizes semi-circular handle 6, the extension of the steel hinge line 7 after curved arrangement is penetrated by bottom surface steel strand perforation 5, and passed by end face steel strand perforation 4; After concrete eight tentatively condenses, just by semi-circular handle 6, whole cave mould can be taken out, after taking-up, just can form a shaping notch.
Cave of the present utility model is molded to be done simply, and with low cost, installation location is convenient, without the need to manually installing template separately, saves labor and materials machine, the reduction of erection time.Concrete formation quality is high, and construction quality is effectively ensured.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
