Description
Technical field
The present invention relates to building implements field, in particular to a kind of i iron fixed mount and method of operating.
Background technology
When building site being carried out the concreting of body of wall, need steel to be embedded in concrete, and then increase the intensity of body of wall, use safety and the long service life of body of wall.
Before concreting, first steel will be fixed on the position of setting, therefore need the fixed mount using steel, the fixed mount of existing installation steel mostly is and adopts inverted U-shaped anchor ring.During use, first inverted U-shaped anchor ring concrete is fixed on the position of setting, the opening direction of U-shaped is towards the bottom surface of body of wall.After anchor ring fixes, then steel being clamped between anchor ring, in order to make clamping better effects if, in the gap of anchor ring and steel, filling sheet material.
Inventor finds under study for action, and when existing concrete is built, the use of fixed mount at least exists following shortcoming:
The mounting process of one, existing fixed mount, fixed mount coordinates inaccuracy with template, easily produces error, and then affects the installation of steel; Two, existing fixed mount mounting process, fixed mount needs to fill sheet material to be fixed steel, and fixed effect is poor, and in casting process, the position change of steel, affects pouring quality; Three, existing fixed mount mounting process, fixed mount is embedded in body of wall, can not reuse, and the utilization rate of material is low.
Summary of the invention
The object of the present invention is to provide a kind of i iron fixed mount method of operating, it is low and can not reusable problem to be intended to improve existing fixed mount installation site accuracy.
Based on above-mentioned purpose; the invention provides a kind of i iron fixed mount; described i iron fixed mount comprises fixed mount main body and protection tube; two backstays that described fixed mount main body comprises the base of template, two nuts and is positioned on described base; described two backstay intervals are arranged; and described two backstays are perpendicular to the plate face of described base, the method comprises:
Step S100, build body of wall before, the position that the formwork for placing of body of wall both sides corresponds to i iron to be fixed marks;
Step S200, mounting and fixing support main body, make the corresponding described position of described backstay run through the described formwork for placing of both sides, and make described protection tube be set on described backstay and be positioned at the scope to be built of described body of wall;
Step S300, installation i iron, make described i iron to be fixed accordingly between described two backstays;
Step S400, installation tighten described nut on described backstay, make described i iron to be fixed be clamped between described base and described nut;
Step S500, body of wall have been built and after solidifying, have been removed described nut and take out described fixed mount main body, making described protection tube be retained in described body of wall.
Preferably, the line of ink marker is adopted to mark or whitewash mark, in actual mechanical process in described step S100, the line of ink marker or to whitewash marking operation simple, result of use is good, after mark, mark is obvious, is not easily spent by wiping or is erased, being convenient to the position that staff accurately installs i iron fixed mount.
Preferably, in described step S200, described base is made to be fitted in the mark of described formwork for placing, on building site, need to use formwork for placing when building, formwork for placing adopts dull and stereotyped, be fitted in by base on formwork for placing, the quality of fit of i iron fixed mount and formwork for placing is high, easy to use.
Preferably; in described step S200; the length of described protection tube is not less than the thickness of described body of wall; protection tube is in casting process; be mainly used for protection objective bar not adhered to by concrete, therefore, the length of protection tube is not less than the thickness of body of wall; after concreting, be convenient to backstay and take out from protection tube.
Preferably, described protection tube is pvc pipe, and the use of pvc pipe is extensive, low cost of manufacture; And there is good tension, compressive strength, and not easily break in casting process, safe and reliable; The resistance of fluid is little, and in casting process, concrete can be good at filling full whole body of wall, good with the tube wall filling effect of pvc pipe, and then the pouring quality of whole body of wall is high; Good corrosion resistance, concrete slurry has certain corrosivity, and in concreting process or after building, protection tube is stayed in body of wall, as a part for body of wall, long service life.
Preferably, in described step S300, between described base and described i iron, place cushion block, the edge of a wing of described i iron is clamped between corresponding two described backstays, the described cushion block and fit in the surface on one of them edge of a wing of described i iron.According to installing by force intensity of i iron, after ensureing that i iron is embedded in body of wall, play best load effect; Meanwhile, i iron easy for installation, simple to operate, after installation, position is fixing not easily moves, and when building, concrete can wrap up i iron fast.
Preferably, in described step S400, before described nut is installed, steel plate is placed between described nut and described i iron, make described backstay through described steel plate, install and after tightening described nut, make described steel plate be clamped between described nut and described i iron.I iron fixing more firm, after being tightened by nut, the coupling mechanism force of nut passes to i iron by steel plate, i iron stressed more even, and fixed effect is better.
Preferably, described backstay is reinforcing bar, and the scope of application of reinforcing bar is wide, toughness and compressive property good, impact force during concreting can be born, not easily bending or fracture, use safety; Meanwhile, reinforcing bar is convenient to further processing, can either increase with floor installation after fastness, be convenient to again i iron to be fixed between two backstays, safe and reliable, easy to use.
Preferably; in described step S400; the screw thread matched with described nut is positioned at and stretches out on the described backstay of described protection tube; be convenient to the processing of screw thread; when namely processing described screw thread, do not need to process on the whole bar of backstay, reduce difficulty of processing; save the time, and then reduce cost.
Preferably; in described step S500; take out described fixed mount main body to comprise: the end for the described nut that is spirally connected of knocking described backstay, the movement vertically of described backstay makes the connection of itself and described protection tube loosen, and pulls described base to depart from described protection tube completely to it.Simple and quick, be convenient to fixed mount main body to take out from body of wall.
Beneficial effect of the present invention:
In sum, i iron fixed mount method of operating provided by the invention, can be arranged on desired location accurately by described i iron fixed mount, and high with the quality of fit of formwork for placing, is convenient to the location of i iron, improves the precision of location; Meanwhile, between two backstays that i iron well can be fixed on i iron fixed mount, the positioning action of i iron is simple, position error is little, alignment quality is high, and then improves pouring quality; Method of operating provided by the invention, in conjunction with the structure of described i iron fixed mount, after finishing using, i iron fixed mount can take out from body of wall, achieves reusing of i iron fixed mount, saves material.
