Abstract
The invention discloses a method for controlling concrete elevation by a steel bar with a hooked end. The method comprises a steel bar support frame and a steel bar hook, wherein the steel bar support frame is welded into an L shape by two steel bars of the same specification; and the steel bar hook is bent to 135 degrees, and is welded with the steel bar support frame. The method comprises the following concrete implementation steps that 1, the two ends of the steel bar support frame are welded with an upper row auxiliary steel bar and a lower row steel bar and are separately arranged in the structure in a way of forming a distance being 1.5m; 2, the bottom end of the steel bar hook is welded with the steel bar support frame, and the length of a part, above the upper row auxiliary steel bar, of the bent end of the steel bar hook, is equal to the thickness of a protection layer; 3, concrete is cast; and 4, the bent end of the steel bar hook is used as an elevation control point of the concrete, and concrete leveling is performed. The method provided by the invention effectively solves the problem of upper part hogging bending steel bar subsidence due to manual treading or concrete casting in the construction process of a large-size concrete floor is effectively solved; the thickness of the steel bar protection layer is ensured; the floor surface elevation is effectively controlled; the manufacturing of components is simple; and the installation is simple.
Description
Technical field
The present invention relates to a kind of method that hooked bar controls concrete absolute altitude.
Background technology
In building construction process; absolute altitude in reinforced concrete structure controls usually by means of 50 lines; and upper placing of reinforcement is usually because trample or casting and compacting of concrete and produce sinking; thickness of protection tier in base plate is difficult to control; concrete effectively reduces by curved cross section, greatly reduces the supporting capacity of structure.In order to avoid this situation, adopt measure reinforcing bar in current work progress, namely common in engineering supporting steel bar or steel bracket form, be arranged on lower rebar and top is born between bar bending, in order to support negative bending moment rib.This way to some extent solves reinforcing bar subsidence problems, but when underplate concrete is built, absolute altitude is difficult to control, and cannot solve the anti-skidding problem on top reinforcement face.
Summary of the invention
The technical issues that need to address of the present invention are, a kind of hooked bar is provided to control the method for concrete absolute altitude, avoid top bear bar bending due to personnel trample or concreting produce sink, effective control panel surface concrete absolute altitude, and hooked bar is easy to make, in work progress, there is skidproof effect, ensure construction safety.
Technical scheme of the present invention is: a kind of hooked bar controls the method for concrete absolute altitude, it is characterized in that: comprise Steel bar rack and reinforcing bar crotch, Steel bar rack is connected into " L " shape by the steel bar welding of two same models, and reinforcing bar crotch bends up 135 °, and welds with Steel bar rack; Concrete implementation step is as follows:
Step one: Steel bar rack two ends are welded with the attached reinforcing bar of upper row and lower placing of reinforcement respectively, and 1.5 meters, interval layout in the structure;
Step 2: reinforcing bar crotch bottom is welded with Steel bar rack, reinforcing bar crotch bends up end, and to exceed length be a protective layer thickness;
Step 3: concreting;
Step 4: utilize reinforcing bar crotch to bend up end as concrete absolute altitude control point, it is floating to carry out concrete.
Preferably, in described step one, the attached reinforcing bar of upper placing of reinforcement is connected with upper placing of reinforcement colligation, and Steel bar rack two ends are welded with the attached reinforcing bar of upper placing of reinforcement and lower placing of reinforcement respectively, prevent from destroying placing of reinforcement structural performance.
Preferably, in described step 2, reinforcing bar crotch top bends up 135 °, and the lap length of bottom and Steel bar rack body is not less than 20cm, and exceeds upper placing of reinforcement 3cm, is a protective layer thickness.
Preferably, in described step 4, hooked bar top is consistent with floor elevation, in floating process, as floor elevation control point, effectively controls floor elevation.
Beneficial effect:
A kind of hooked bar of the present invention controls the method for concrete absolute altitude; efficiently solve mass concrete invert in work progress; because people bears bar bending subsidence problems for the top of trampling or concreting produces, ensure that the thickness of reinforcement cover, effectively control floor elevation.In addition, the hook portion of bar with hooked end, also have anti-skidding, trample supporting role, and make simple, convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of hooked bar.
Fig. 2 is the detail of construction of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Fig. 1 to 2, for a kind of hooked bar of the present invention controls the embodiment 1 of the method for concrete absolute altitude, comprise Steel bar rack 1 and reinforcing bar crotch 2, described Steel bar rack 1 comprises Steel bar rack body 11 and is welded on the reinforcing bar diagonal brace 12 of Steel bar rack 1 bottom, described Steel bar rack body 11 and reinforcing bar diagonal brace 12 are the reinforcing bar of same model, are welded into " L " shape.
In the implementation case, after treating the double-layer double-direction reinforcing bar binding of base plate, the diagonal brace reinforcing bar 12 of " L " shape Steel bar rack 1 is welded with lower placing of reinforcement 4, Steel bar rack body 11 welds with the attached reinforcing bar 3 of upper row, the attached reinforcing bar of upper placing of reinforcement 3 is connected with the colligation of upper placing of reinforcement 5, can prevent from destroying placing of reinforcement structural performance.Then reinforcing bar crotch diameter being slightly less than Steel bar rack is welded into entirety with " L " shape Steel bar rack; and welded lap length is 20cm; reinforcing bar crotch bends up 135 ° down; bend up operative tip and exceed upper row 3cm; be a protective layer thickness of reinforcing bar; and consistent with floor elevation, can floor elevation be controlled, can provide again trample support and anti-skidding.
Below only just the present invention preferably example be described, but can not be interpreted as it is limitations on claims.The present invention is not only confined to above example, its concrete structure size allows to change, those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
