Abstract
The invention provides a tool die plate for a circular hole concrete structure. The tool die plate comprises two semicircular-arc-shaped rebar supports arranged in a circular hole and a three-ply plate of which the periphery is tightly attached to the rebar supports. Each rebar support comprises an upper layer of rebars and a lower layer of rebars and is of a semicircular-arc-shaped structure. Two rebar supporting rods are arranged, and the three-ply plate is bent and is tightly attached to the rebar supports in a bound manner. The tool die plate has the beneficial effects that when well lid plate concrete construction is checked, the tool die plate is put on the circular hole position of the lid plate, and the rebars of the lid plate can be bound; after concrete final set, the portion, of the semicircular-arc-shaped structure, of the tool die plate is disassembled, then the other portion, of the semicircular-arc-shaped structure, of the tool die plate is disassembled, the working efficiency is higher, the circular hole structure edge can be prevented from being damaged when a die is disassembled, the circular hole structure is regular, and the appearance quality is good; and the set tool die plate can be reused, and the cost is saved.
Description
Technical field
The present invention relates to a kind of circular hole xoncrete structure tool palette, be particularly well-suited to the formwork of municipal administration inspection shaft concrete prefabricated cover plate borehole structure, belong to the realm of building construction.
Background technology
Along with the continuous extension in city, town road construction gets more and more, and municipal administration supporting pipelines also gets more and more along with the construction of road, and as checking, keep in repair, the inspection shaft of the municipal supporting pipelines of the function such as conversion be also requisite structures.The generally circular in cross section structure of inspection shaft concrete cover manhole, a diameter of 700mm, its manhole formwork typically uses brick loose tool, tyre mould and three-ply board template, circular configuration model sheetinstallat is complicated, waste time and energy, and due to the phenomenon such as borehole structure deformation, circular hole all can be caused non-round such as template deformation when the easy deviation of circular hole model sheetinstallat, template inner support unbalance stress and vibrated concrete, directly affect the impression quality of cover plate and use function.
Summary of the invention
The technical issues that need to address of the present invention are, a kind of circular hole xoncrete structure tool palette of design, field fabrication, simple installation, borehole structure is regular, and the canalization tool palette that can reuse.
The technical scheme is that a kind of circular hole xoncrete structure tool palette, be close to the three-ply board of Steel bar rack including two the semicircular arc Steel bar racks being arranged in circular port and periphery.
Preferably, described Steel bar rack, including bilevel reinforcing bar, use some bar dowels to be welded to connect by upper and lower two-layer reinforcing bar.
Preferably, described Steel bar rack, is semicircular arc structure, and each semi arch Steel bar rack arranges two reinforcement bar support struts.
Preferably, described three-ply board, is that after bending, Steel bar rack is close in colligation, and the half of its a length of concrete component circular 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 to be fixed together through aperture and Steel bar rack colligation.
Preferably, described circular hole xoncrete structure tool palette, is the borehole structure formed that two semicircular arc Steel bar racks (containing three-ply board) is bolted together.
After using the technical program, during the construction of manhole cover board concrete, after inventive article template 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.

Accompanying drawing 1 is inspection shaft concrete cover plane graph.
Accompanying drawing 2 is plane graph of the present invention.
Accompanying drawing 3 is three-ply board plane graph of the present invention.
Accompanying drawing 4 is semi arch structure chart of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As shown in Figures 1 to 4, the invention mainly comprises circular arc reinforcing bar (11,12), bar dowel (13), reinforcement bar support strut (14), three-ply board (2) and thin wire (3).Half-circle-arc shape is become to form circular arc reinforcing bar (11 bar bending according to circle hole radius size, 12), it is 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 distance circular arc reinforcing bar (11,12) respectively weld a reinforcement bar support strut (14) at a small distance of termination, thus form the Steel bar rack (1) of semi arch structure.
Setting-out cutting three-ply board (2), its length L is the half of component circular hole girth, width B is the thickness of concrete cover, descend two-layer circular arc reinforcing bar (11 thereon, 12) two row's apertures (21) are made a call in position, after three-ply board (2) is bent into half-circle-arc shape, iron wire (3) is used to be fixed together through aperture and circular arc reinforcing bar (11,12) colligation.
Be bolted together formation circular hole xoncrete structure tool palette by two semicircular arc Steel bar racks (1) after colligation three-ply board (2).
The present invention makes the work efficiency pouring inspection shaft concrete cover become higher, and after form removal, borehole structure is regular, and impression quality is good, and can reuse, cost-effective.
Below only the present invention preferably example is described, but is not to be construed as limitations on claims.The present invention is not only limited to above example, and its concrete structure allows to change, and those skilled in the art can be variously modified according to the present invention and deform, and without departing from the spirit of the present invention, all should belong to scope defined in claims of the present invention.
