B, weld bolt head：After column foundation cushion cap concreting, rim of a cup reinforcement foundation is installed, rim of a cup core and back of the body side is installed, one section of Screw arbor with nut at both-ends is respectively welded and fixed on the top of two tension ribs；
Depression bar is installed c,：It is pressed in using two steel pipes as depression bar on rim of a cup core and back of the body side, and is placed on the both sides of Screw arbor with nut at both-ends, both ends is withheld into two steel pipes using 3 types, and tightened on Screw arbor with nut at both-ends with nut and fix 3 type cards；
D, rim of a cup post concrete is poured：After the completion of above-mentioned steps a-c work, rim of a cup base concrete is poured, cup column foundation core will not float under the pulling force of tension rib and the pressure of depression bar, form a kind of float Structure, not changed to ensure that rim of a cup lower concrete pours absolute altitude.
The cup column foundation core anti-float method of the present invention can also be further achieved by the following technical measures.
Foregoing method, wherein the Screw arbor with nut at both-ends is long 200mm full flight screw.
Foregoing method, wherein the steel pipe is scaffolding steel pipe.
After adopting the above technical scheme, the cup column foundation core anti-float method of the present invention has advantages below：
1st, tension rib is done using rim of a cup muscle, using to pull bar group tension rib thread head, makees depression bar using steel pipe, fixation is tightened using 3 type cards and to rod nut, material local use, is operable without professional；
2nd, anti-floating body is utilized, it is possible to reduce unnecessary dabbing processing, avoid secondary cleaning work, improve production efficiency, save construction cost；
3rd, simple to operate, installation accuracy is guaranteed.
Brief description of the drawings
Fig. 1 is the cup column foundation core anti-floating schematic diagram of the embodiment of the present invention；
Fig. 2 is A-A sectional views in Fig. 1；
Fig. 3 is P positions enlarged drawing in Fig. 1.
In figure：1 base for post rim of a cup, 2 steel pipes, 3 rim of a cup cores and back of the body side, 4 column foundation cushion caps, 5 rim of a cup foundation forms and back of the body side, 6 tension ribs, 7 Screw arbor with nut at both-ends, 8 cores, 9 nuts, 103 type cards.
Embodiment
With reference to embodiments and its accompanying drawing illustrates further to the present invention.
Embodiment 1
The kind cup column foundation core anti-float method of the present invention, comprises the following steps：
Referring now to Fig. 1-Fig. 3, Fig. 1 is the cup column foundation core anti-floating schematic diagram of the embodiment of the present invention, and Fig. 2 is A-A sectional views in Fig. 1, and Fig. 3 is P positions enlarged drawing in Fig. 1.A, stay and set tension rib 6：In column foundation 4 reinforcement installation of cushion cap, the side sideline center of corresponding base for post rim of a cup 1, which is respectively stayed, sets one with base for post rim of a cup reinforcing bar same specification and the steel tie 6 of size.
B, weld bolt head：After column foundation cushion cap concreting, rim of a cup reinforcement foundation is installed, installs rim of a cup core and rim of a cup side form, one section of Screw arbor with nut at both-ends 7 for being provided with the long full threads of 200mm is respectively welded and fixed on the top of two tension ribs 6.
Depression bar is installed c,：It is pressed in two steel pipes 2 as depression bar on rim of a cup core and back of the body side 3, and is placed on the both sides of Screw arbor with nut at both-ends 7, both ends is clasped into two steel pipes 2 using 3 type cards 10, and tightened on Screw arbor with nut at both-ends 7 with nut 9 and fix 3 type cards；
D, rim of a cup post concrete is poured：After the completion of above-mentioned steps a-c work, rim of a cup base concrete is poured, cup column foundation core will not float under the pulling force of tension rib 6 and the pressure of depression bar, form a kind of float Structure, not changed to ensure that rim of a cup lower concrete pours absolute altitude.The steel pipe 2 is scaffolding steel pipe.
The present invention has substantive distinguishing features and significant technological progress, cup column foundation core anti-float method of the invention, using tension rib and depression bar is set on rim of a cup core, forms a kind of anti-floating body, ensures that core is non-rising when rim of a cup base concrete pours.The cup column foundation core anti-float method of the present invention is more easy to ensure the precision of rim of a cup bottom absolute altitude than cutting processing method behind traditional rim of a cup bottom, it not only reliably ensure that the installation requirement of factory building columns, also reduce construction cost simultaneously, the construction period is saved, being particularly in architectural engineering in industrial building construction of hydropower has general applicability and typicalness.
Used in cup column foundation core anti-float method Baosteel Zhanjiang steel cold rolling engineering of the present invention, finished product reservoir area, the main buildings such as electrical sheet area are both designed as cup column foundation, quantities is big, quantity is more, require high plus Baosteel construction quality, if conventional treatment method is taken to cup column foundation, duration and installation quality requirement can not be met, live material is utilized through researching and analysing, using reinforcing bar, to drawhead, 3 type cards, to rod nut, a kind of simple anti-floating body of the combination settings such as scaffolding steel pipe, ensure that the bottom absolute altitude one-shot forming on rim of a cup basis meets design requirement, ensure factory building columns installation quality.This method not only reliably ensure that installation quality, while also reduce construction cost, save the construction period.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or change.Therefore, all equivalent technical schemes should also belong to scope of the invention, should be limited by each claim.
