Abstract
The invention discloses an adjustable steel chisel for controlling the thickness of a floor slab on site, which comprises a solid tube, a conical sheet and a round sheet; the middle part of the solid tube is provided with a circular sheet which is sleeved on the solid tube and can move under stress; one end of the solid tube is provided with a conical sheet, and the diameter of the conical sheet is gradually reduced from the round sheet to the round sheet; scales are arranged on the solid tube; the scales are arranged between the conical steel sheet and the circular steel sheet. The floor thickness is accurately controlled on site as a concrete structure engineering, the design requirement of the structure is guaranteed, the concrete waste is reduced, and the floor thickness control system is energy-saving and environment-friendly.
Description
Technical Field
The invention relates to the technical field of site floor thickness control of building concrete structural engineering, in particular to an adjustable steel chisel for site floor thickness control.
Background
In the high-rise residential building engineering, the cast-in-place reinforced concrete structure floor slab is widely applied, and the control of the thickness of the construction plate is a difficult problem which puzzles the construction personnel for a long time. As is known, the exceeding and the reduction of the thickness of the floor slab can cause a series of problems of increased central deflection, increased self-weight of the structure, insufficient bearing capacity of the structure, cracking of the floor slab and the like, thereby not only influencing the later construction quality and efficiency, but also reducing the reputation of enterprises.
At present, the most common construction site is still the traditional method for controlling the floor elevation to reversely control the thickness of the floor according to '50' line control, namely, the floor elevation is vertically transmitted through a height marking line, 50 lines are marked on the longitudinal ribs of the floor column, after the formwork is erected, the height marking lines of the longitudinal ribs of the corner columns of each plate are connected, and a pull-through line is used for rechecking the horizontal range difference and the mid-span arching height of the floor. The method belongs to a passive control method, is convenient to operate and is easy to master. However, the column longitudinal bars cannot be kept still, and the middle of the drawn white line will generate a certain deflection and sink, so the effectiveness of controlling the thickness of the floor slab is not ideal, and the floor flatness is poor.
Disclosure of Invention
The invention aims to solve the problems of providing an adjustable drill steel device which is simple to manufacture, convenient to operate and move and can be used for different thicknesses, so that the defects of passive control, instability and the like of the traditional '50' line control elevation reverse control floor thickness are overcome, the flexibility and the safety of construction site operation are ensured, and the qualified rate of the floor thicknesses is improved.
In order to achieve the above purpose, the invention provides the following technical scheme:
an adjustable steel chisel for controlling the thickness of a floor board on site comprises a solid tube, a conical sheet and a round sheet; the middle part of the solid tube is provided with a circular sheet which is sleeved on the solid tube and can move under stress; one end of the solid tube is provided with a conical sheet, and the diameter of the conical sheet is gradually reduced from the round sheet to the round sheet; scales are arranged on the solid tube; the scales are arranged between the conical steel sheet and the circular steel sheet.
Further, the solid tube is a cylindrical solid tube. The cylindrical shape is convenient to use.
Further, the solid pipe is a steel pipe. The steel pipe is adopted for preparation, so that the cost is low, and the steel pipe is firm and durable.
Further, the conical sheet and the circular sheet are both steel sheets.
The invention has the following beneficial effects: the steel chisel for controlling the thickness of the floor slab on site has the advantages of simple processing, convenient operation, safety, high efficiency and civilization. The floor thickness is accurately controlled on site as a concrete structure engineering, the design requirement of the structure is guaranteed, the concrete waste is reduced, and the floor thickness control system is energy-saving and environment-friendly.
1. The device is simple to manufacture, and the thickness of the floor plate can be effectively controlled;
2. the accuracy of final floating of the concrete floor is accelerated, and the qualification rate is improved.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of a portion of the present invention;
fig. 3 is a top view of the present invention.
Wherein: 1. a cylindrical solid steel tube; 2. a conical steel sheet; 3. a circular steel sheet.
Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention.
Example 1
As shown in the figure, the adjustable steel chisel for controlling the thickness of the floor plate on site comprises a cylindrical solid steel pipe, a conical steel sheet and a round steel sheet; the middle part of the cylindrical solid steel pipe is provided with a circular steel sheet which is sleeved on the cylindrical solid steel pipe and can move under stress; one end of the cylindrical solid steel pipe is provided with a conical steel sheet, and the diameter of the conical steel sheet is gradually reduced from the position close to the circular steel sheet to the position far away from the circular steel sheet; scales are arranged on the cylindrical solid steel pipe; the scales are arranged between the conical steel sheet and the circular steel sheet.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
