Abstract
The utility model comprises a counter screw for shuttering which mainly comprises a fixed distance press screw, locating press irregular nuts in screwed connection with both ends of the fixed distance press screw as well as fixed length press screws in screwed connection with the bottoms of the press irregular nuts, therein, both ends of the fixed length press screws are provided with screw threads, the locating press irregular nuts take the shape of cones. Compared with the prior art, the utility model has the advantages of small spacing error between the shutterings, easy shutting alignment, material saving, easy shuttering disassembly, manpower saving, efficiency improvement, and can greatly prolong the service life of the shutterings.
Description
Technical field:
The utility model relates to a kind of instrument for building, particularly a kind of template Screw arbor with nut at both-ends.
Background technology:
The existing templates Screw arbor with nut at both-ends is a screwed iron in two ends.During use, many Screw arbor with nut at both-ends are passed between two templates, be arranged between template with location object (as having set the bar dowel of length) then, to fix the distance between two templates, cross-under one location fan-deck card and nut is provided with flitch and steel pipe between fan-deck card and template on the threaded iron in the template outside, screws the nut at iron two ends then, by fan-deck card, steel pipe, flitch template is fixed, then casting cement between template.There is following shortcoming in this kind Screw arbor with nut at both-ends:
1, the interval error between template is big, is difficult for the alignment template.Spacing between template is influenced by the mismachining tolerance of spacing object and placement form, can cause the interval error between template big, is not easy the alignment template, causes the concrete body size of building error to occur.
2, waste material, lost labor.Behind the casting cement, stretch out the outer iron of cement and can only excise and throw aside, in order to avoid influence normal safe construction.
3, dismounting template difficulty is damaged template easily.Because template is penetrated the location by many irons, during the dismounting template, must allow template move along iron, template could be disassembled from the cement that solidifies, and the area of template is very big often, is very difficult with manually the very big template of area is moved along many irons, and is subjected to the restriction of operator's operant level, during the dismounting template, template is damaged easily.
Goal of the invention of the present utility model is to provide little, the easy alignment template of the interval error between a kind of template, material saving, template dismounting to be easy to the template Screw arbor with nut at both-ends.
The utility model is to realize like this, mainly constitute by spacing pressurized screw rod, the location pressurized abnormity nut that is threaded in spacing pressurized screw rod two ends, the regular length tension screw rod that is threaded in pressurized abnormity nut bottom surface, location, the two ends of regular length tension screw rod are equipped with screw thread, and location pressurized abnormity nut is coniform.During use, at first two location pressurized abnormity nuts are tightened on the two ends of spacing pressurized screw rod respectively, next places it in the middle of two templates, the location pressurized abnormity nut that then supporting regular length tension screw rod is passed in template and the template is connected, fan-deck card and nut in cross-under on the regular length tension screw rod, between fan-deck card and template, put flitch, steel pipe, screw nut then, pass through fan-deck card, steel pipe is pressed on flitch on the template, because the length of spacing pressurized screw rod is according to setting dimensioned, location pressurized abnormity nut has the jacking effect to template, like this, cooperate fan-deck card to use, just need not just the fixed distance between two templates can be got off by the spacing object, can not only accurately set the spacing between template like this, lower the error of spacing between template significantly.Behind the fluid concrete, when needing the dismounting template, earlier fan-deck card, steel pipe, flitch are disassembled, take out regular length tension screw rod, at this moment, template outer without any obstruction, only need template is peeled off from concrete, just can take out template, after the dismounting template, on the concrete without any ridge, location pressurized abnormity nut can be from concrete takes out with special tool be reused.
Here, be provided with the hole of at least two symmetries in the bottom surface of location pressurized abnormity nut.Corresponding aperture is provided with a pulling tool, and pulling tool is a metal bar, and the hole of the corresponding location of the end face of rod pressurized abnormity nut is provided with pillar, and the other end of rod is provided with perforation.During work, pillar on the metal bar end face is inserted the hole of locating on the pressurized abnormity nut bottom surface, in the perforation of rod, insert iron, pull iron, just location pressurized abnormity nut can be tightened on the spacing pressurized screw rod or will locate the pressurized abnormity nut from the spacing pressurized screw rod and remove.
With instrument regular length tension screw rod is tightened on the pressurized abnormity nut of location or from location pressurized abnormity nut for convenience and takes off regular length tension screw rod, the termination of regular length tension screw rod is tabular.
The utility model compared with the prior art, have little, the easy alignment template of interval error between template, material saving, template dismounting easily, save artificial, raise the efficiency, can prolong the template advantage in application life significantly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model;
Fig. 3 is the structural representation of pulling tool.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model mainly is made of spacing pressurized screw rod 1, the coniform location pressurized abnormity nut 2 that is threaded in spacing pressurized screw rod 1 two ends, the regular length tension screw rod 3 that is threaded in pressurized abnormity nut 2 bottom surfaces, location, the two ends of regular length tension screw rod 3 are equipped with screw thread, are provided with the hole 4 of two symmetries in the bottom surface of location pressurized abnormity nut 2.Corresponding aperture is provided with a pulling tool 5, and pulling tool 5 is metal bars, and the hole 4 of the corresponding location of the end face of rod pressurized abnormity nut 2 is provided with pillar 6, and the other end of rod is provided with perforation 7, and the termination 7 of regular length tension screw rod 3 is tabular.During use, it is fixing with template 12 to pass through fan-deck card 8, nut 9, steel pipe 10, flitch 11.
