Abstract
This utility model provides a kind of circular hole xoncrete structure tool palette, the three-ply board of Steel bar rack it is close to including two the semicircular arc Steel bar racks being arranged in circular port and periphery, Steel bar rack includes upper and lower two-layer reinforcing bar, Steel bar rack is semicircular arc structure, and two reinforcement bar support struts are set, after three-ply board bends, Steel bar rack is close in colligation.The beneficial effects of the utility model are: during the construction of manhole cover board concrete, after this tool palette is placed in cover plate circular hole position, get final product the reinforcing bar of colligation cover plate.After concrete final set, first removing the tool palette of half arc structure, then remove the tool palette of other half arc structure, work efficiency is higher, and damages borehole structure seamed edge when being possible to prevent form removal, makes borehole structure regular, and impression quality is good.This canalization tool palette can reuse, cost-effective.
Description
Technical field
This utility model relates to a kind of circular hole xoncrete structure tool palette, is particularly well-suited to municipal administration inspection shaft concrete pre-
The formwork of cover plate borehole structure processed, belongs to the realm of building construction.
Background technology
Along with the continuous extension in city, town road construction gets more and more, municipal administration supporting pipelines along with road construction also
More and more, and as checking, keep in repair, the inspection shaft of the municipal supporting pipelines of the function such as conversion be also requisite constructing
Thing.The generally circular in cross section structure of inspection shaft concrete cover manhole, a diameter of 700mm, its manhole formwork typically uses brick tire
Mould, tyre mould and three-ply board template, circular configuration model sheetinstallat is complicated, wastes time and energy, and due to the easy deviation of circular hole model sheetinstallat,
When template inner support unbalance stress and vibrated concrete, template deformation etc. all can cause borehole structure deformation, circular hole non-round etc. existing
As, directly affect the impression quality of cover plate and use function.
Summary of the invention
This utility model technical issues that need to address are, a kind of circular hole xoncrete structure tool palette of design, on-the-spot system
Work, simple installation, borehole structure is regular, and the canalization tool palette that can reuse.
The technical solution of the utility model is: a kind of circular hole xoncrete structure tool palette, including being arranged in circular port
Two semicircular arc Steel bar racks and periphery be close to the three-ply board of Steel bar rack.
Preferably, described Steel bar rack, including bilevel reinforcing bar, use some bar dowels by upper and lower two-layer
Reinforcing bar is welded to connect.
Preferably, described Steel bar rack, is semicircular arc structure, and each semi arch Steel bar rack arranges two reinforcing bars
Support bar.
Preferably, described three-ply board, is that after bending, Steel bar rack is close in colligation, its a length of concrete component circle
The half of hole girth, width is the thickness of component.
Preferably, described three-ply board, is to make a call to two row's apertures in upper and lower two-layer Steel bar rack position, uses iron wire through little
Hole is fixed together with Steel bar rack colligation.
Preferably, described circular hole xoncrete structure tool palette, is (to be closed containing three by two semicircular arc Steel bar racks
Plate) be bolted together the borehole structure formed.
After using the technical program, during the construction of manhole cover board concrete, place this utility model in cover plate circular hole position
After tool palette, get final product the reinforcing bar of colligation cover plate.After concrete final set, first remove the tool palette of half arc structure, then tear open
Except the tool palette of other half arc structure, work efficiency is higher, and damages borehole structure seamed edge when being possible to prevent form removal,
Making borehole structure regular, impression quality is good.This canalization tool palette can reuse, cost-effective.
Accompanying drawing explanation
Accompanying drawing 1 is inspection shaft concrete cover plane graph.
Accompanying drawing 2 is this utility model plane graph.
Accompanying drawing 3 is this utility model three-ply board plane graph.
Accompanying drawing 4 is this utility model semi arch structure chart.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
As shown in Figures 1 to 4, this utility model mainly includes circular arc reinforcing bar (11,12), bar dowel (13), reinforced bar support
Bar (14), three-ply board (2) and iron wire (3).Half-circle-arc shape is become to form circular arc reinforcing bar bar bending according to circle hole radius size
(11,12), are fixed by welding some bar dowels (13) between upper strata circular arc reinforcing bar (11) with lower floor's circular arc reinforcing bar (12),
At a small distance of distance circular arc reinforcing bar (11,12) termination, respectively weld a reinforcement bar support strut (14), thus form semicircle
The Steel bar rack (1) of arc structure.
Setting-out cutting three-ply board (2), its length L is the half of component circular hole girth, and width B is the thickness of concrete cover
Degree, descends two-layer circular arc reinforcing bar (11,12) position to make a call to two row's apertures (21) thereon, three-ply board (2) is bent into half-circle-arc shape
After, use iron wire (3) to be fixed together through aperture and circular arc reinforcing bar (11,12) colligation.
Be bolted together formation circular hole concrete knot by two semicircular arc Steel bar racks (1) after colligation three-ply board (2)
Structure tool palette.
This utility model makes the work efficiency pouring inspection shaft concrete cover become higher, borehole structure rule after form removal
Whole, impression quality is good, and can reuse, cost-effective.
Below only this utility model preferably example is described, but is not to be construed as limitations on claims.
This utility model is not only limited to above example, and its concrete structure allows to change, and those skilled in the art can be according to this reality
It is variously modified with novel and deform, without departing from spirit of the present utility model, the appended power of this utility model all should be belonged to
Profit requires defined scope.
