Description
Technical field
The utility model is related to a kind of toolings, and in particular to and a kind of super plane earth post-cast strip flatness accurately controls tooling,
Belong to the super plane earth post-cast strip flatness precise control device technical field of concrete.
Background technology
Industrial premises installs the requirement of accurate flatness due to equipment, therefore the requirement to mattess is higher and higher, and one
Class terrace requires every 2 meters of height difference to be no more than ± 3mm, but in terrace casting process, for post-cast strip it is secondary pour it is smooth
It controls relatively difficult.First post-cast strip is usually arranged, needs to be separated when pouring ground, while separating both sides absolute altitude requirement one
It causes；Second post-cast strip usually carries out after 28 days, and using the slightly expanded concrete for the concrete grade that is above the ground level, therefore to staying
If both sides absolute altitude requires stringent when post-cast strip, the precision for large area concrete post-cast strip flatness is difficult control, therefore, is compeled
A kind of device of needs for cutting solves above-mentioned technical problem.
Invention content
The utility model exactly for the technical problems in the prior art, it is smooth to provide a kind of super plane earth post-cast strip
Degree accurately controls tooling, and the Technical Design is a kind of controlling post-cast strip both sides absolute altitude within the scope of ± 1mm, ensure whole
A mattess reaches a kind of terrace standard, and total advantages of simple, work efficiency is high, and accuracy is high, construction is simple.
To achieve the goals above, the technical solution of the utility model is as follows, a kind of super plane earth post-cast strip flatness essence
Really control tooling, which is characterized in that the control tooling includes angle steel, band steel and bolt, and bolt hole is opened up on the angle steel,
The bolt welding is for fixing on reinforcing bar, and angle steel is placed in both sides after fixing, and after angle steel is placed, centre is connected with band steel, after
It pours and removes screw rod and band iron before band pours, roller ground grading is used after dismounting
As a kind of improvement of the utility model, the aperture of the bolt hole is 12mm, a diameter of 12mm of bolt, adjacent
Spacing between bolt hole is not less than 500mm.In order to improve the controllability of angle steel absolute altitude, bolt select it is longer can tighten or
Loosen, ensures control post-cast strip both sides absolute altitude.
As a kind of improvement of the utility model, the width of the band steel is 40mm.In order to be poured after casting process prevents
Angle steel with both sides is subjected to displacement or sideslip, and after for use bolt has controlled absolute altitude, with band steel by both sides Bolted angle connection, band steel is long
Degree is consistent with post-cast strip width.The control tooling further includes cushion block, and the cushion block is arranged in stud base.The bolt
It, can be in stud base's adjunction cushion block, to ensure bolt tune if bolt length falls short of when being welded to connect with ground reinforced mesh
Save length.
Compared with the existing technology, the utility model has the following advantages that, 1）The technical solution global design is ingenious, structure is tight
It gathers, 2）The technical solution is simple and practical in structure, and the super plane earth post-cast strip flatness described in the program accurately controls tooling, by
In the template with angle steel as post-cast strip both sides, then it is subject to bolt up and down adjustment control angle steel absolute altitude, finally with band steel by both sides
Angle steel is connected, and has simple and reasonable, and flatness is controllable, after the advantages that being poured onto straightness, be particularly suitable for all post-cast strips
Accurate flatness control；3）The technical solution cost is relatively low, is promoted and applied convenient for further.
Description of the drawings
Fig. 1 is the utility model planar structure schematic diagram；
Fig. 2 is sectional view；
In figure：1, angle steel, 2, band steel, 3, bolt, 4, double nut, 5, parallels, 6, roller.
Specific implementation mode：
In order to deepen the understanding to the utility model, the present embodiment is described in detail below in conjunction with the accompanying drawings.
Embodiment 1：Referring to Fig. 1, Fig. 2, a kind of super plane earth post-cast strip flatness accurately controls tooling, the control tooling
Including angle steel 1, band steel 2, bolt 3, double nut 4, parallels 5, roller 6, bolt hole is opened up on the angle steel, the bolt welding exists
For fixing on reinforcing bar, angle steel is placed in both sides after fixing, and after angle steel is placed, centre is connected with band steel, the aperture of the bolt hole
For 12mm, a diameter of 12mm of bolt, the spacing between adjacent bolt hole is not less than 500mm.It can in order to improve angle steel absolute altitude
Control property, bolt select it is longer can tighten or loosen, ensure that control post-cast strip both sides absolute altitude, the width of the band steel are
40mm.In order to prevent the angle steel of post-cast strip both sides to be subjected to displacement or sideslip in casting process, after for use bolt has controlled absolute altitude,
With band steel by both sides Bolted angle connection, band steel length is consistent with post-cast strip width, and screw rod and band iron are removed in post-cast strip before pouring,
Roller ground grading is used after dismounting.
Application example：
Referring to attached drawing 1, which includes:Angle steel 1（50#）, band steel 2（Width 40mm）, bolt 3（Its diameter 12mm）, it is double
Nut 4（A diameter of 12mm）, parallels 5, roller 6,50# angle steel is arranged in the post-cast strip both sides, and bolt hole is opened up on angle steel,
Aperture 12mm, spacing are not less than 500mm, and bolt welding, for fixing, is placed on reinforcing bar after bolt is fixed with reinforcement welding
Angle steel, both sides angle steel, which is placed, to be completed, and centre is connected with band steel, for controlling post-cast strip width in casting process, finally with making
Use leveling apparatus（Accuracy ± 1mm/1.5m）It is accurately levelling by way of tightening nuts.
In order to ensure that this tooling does not shift in casting process, every 500mm, one group of bolt hole is set, it is described such as
Shown in Fig. 2.In use, being first welded on bolt on the reinforced mesh of ground according to bolt hole position, angle steel is being passed through into bolt hole
It is positioned in surfacing steel bar mesh sheet, staff adds laser leveling equipment, is measured once every 500mm, passes through regulating nut
Entire angle steel surface level is controlled, the first preliminary adjusting adjusts completion and connects both sides angle steel with band steel, prevents position inside and outside angle steel
Move, connected with band iron and ensure post-cast strip width, after the installation of last band iron, then carry out the accurate levelling flatness of last time reach ±
1mm, straightness reach ± 2mm.
It should be noted that above-described embodiment, is not used for limiting the scope of protection of the utility model, in above-mentioned technical side
