Cast-in-place concrete floor thickness controller and its method

Abstract

The invention relates to a thickness controller of a cast-in-place concrete floor and a method of the thickness controller of the cast-in-place concrete floor. The controller comprises round steel, steel cushion slices and a sleeve pipe. Two ends of the round steel are threaded. Three steel cushion slices are arranged on the round steel, wherein one slice is a fixed steel cushion slice and the other two slices are movable steel cushion slices which are respectively arranged on upper and lower surfaces of a template. The sleeve pipe is arranged between the fixed steel cushion slice and the movable steel cushion slices and sleeved on the round steel. The method of the thickness controller of the cast-in-place concrete floor includes the following steps. A twist drill is used for drilling a hole in a plate bottom template before the concrete is cast. The sleeve pipe is cut and then sleeved on the round steel, and a steel cushion slice is sleeved on the round steel again. The round steel penetrates the hole in the plate bottom template. A steel cushion slice is additionally arranged below the plate bottom template and screwed tightly through a screw nut. In time of casing with concrete, an upper surface of the steel cushion slice welded above the round steel is used as panel elevation control. After the concrete is congealed, the round steel is removed. A sleeve pipe hole is used as a detection hole of thickness of a floor when an entity is detected. The thickness controller of the cast-in-place concrete floor and the method of the thickness controller of the cast-in-place concrete floor can control all sorts of plates with thickness ranging from 80mm to 320mm.

Description

technical field [0001] The invention relates to the field of concrete floor slabs in the technical field of construction, in particular to a controller for the thickness of cast-in-place concrete floor slabs and a method thereof. Background technique [0002] In construction engineering, the thickness of the cast-in-place concrete floor slab is controlled by copying the elevation and drawing the white line on the side formwork of the slab or the column inserting reinforcement. Since the workers have to continuously use the ruler to control the concrete during the pouring process, the operation is cumbersome and the error It is also large, especially in the construction of long-span beam-slab structures, due to the arching in the center of the beam, it is impossible to pull wires to control the thickness of the concrete, resulting in insufficient concrete thickness at the arching part.
