Abstract

The invention discloses a thickness control inspection tool and inspection method of a multi-thickness cast-in-place floor. Thickness control inspection can be conducted on a cast-in-place structure rapidly by one person, and the floor thickness can be adjusted at any time before initial set of cast-in-place floor concrete. The method comprises the specific implementation steps that the multi-thickness cast-in-place floor thickness control inspection tool 1 is manufactured in advance according to the thickness of the floor, a handlebar 11 of the multi-thickness cast-in-place floor thickness control inspection tool 1 is held in hand, the lower portion 12 of a vertical rebar 1 is vertically inserted into the floor concrete until the bottom end of the lower portion 12 of the vertical rebar 1 makes contact with a floor formwork, whether contact of the construction floor concrete in thickness is realized or not is observed according to different floor thickness positioning bars on the vertical rebar 1, the concrete submerges the positioning bars in thickness at the position, the concrete thickness part at the position is removed to be flush with the positioning bars, and the design thickness of the floor concrete is realized; the concrete can not make contact with the positioning bars in thickness, the concrete is correspondingly filled to be flush with the positioning bars, and thus the design thickness of the floor concrete is realized.

Description

A kind of many thickness cast-in-situ floor THICKNESS CONTROL instruments of inspection and the method for inspection

Technical field

The present invention relates to a kind of many thickness cast-in-situ floor THICKNESS CONTROL instruments of inspection and the method for inspection, relate in particular to a kind of instruments of inspection and its method of inspection that the slab thickness before the initial set of cast-in-place structural floor concrete is controlled.

Background technology

The regulation of < < concrete structure construction inspection of quality standard GB50204-2002 (2011 editions) > >, cast-in-place structural permissible variation in dimension and the method for inspection: sectional dimension permissible variation+8,-5mm, the method for inspection is steel ruler inspection.

But floor concrete was built the inspection method that adopts bracing wire and steel ruler to combine in the work progress before initial set in the past.But often, because a variety of causes causes slab thickness excessive or too small, affect structural safety when plate is thin, during thickness of slab, deadweight strengthens, head room diminishes, wastes material and construction quality is also difficult to ensure.

Summary of the invention

The present invention is in order to make within cast-in-place structural sectional dimension can be controlled at permissible variation scope, the disadvantage that needs many people to coordinate while avoiding the check of cast-in-situ floor concrete THICKNESS CONTROL.The present situation that needs many people to coordinate when the present invention combines check, a kind of many thickness cast-in-situ floor THICKNESS CONTROL instruments of inspection and the method for inspection are proposed, a people can, fast to the control test of cast-in-place structural slab thickness, adjust at any time the thickness of plate before the initial set of cast-in-situ floor concrete.

The technical solution adopted for the present invention to solve the technical problems is:

Described a kind of many thickness cast-in-situ floor THICKNESS CONTROL instruments of inspection and the method for inspection, it comprises a hand-held vertical reinforcing bar.A described hand-held vertical reinforcing bar upper end is handgrip, the bottom of a described hand-held vertical reinforcing bar is respectively welded with one of the spacer bar of different length at the four direction of surface level, the thickness that the distance of the lower bottom end of the described vertical reinforcing bar of described every spacer bar distance is different floors, described spacer bar is grown from being short to successively from the bottom of vertical reinforcing bar, screw arranges.

The invention has the beneficial effects as follows the disadvantage that needs many people to coordinate while avoiding the front THICKNESS CONTROL check of cast-in-situ floor concrete initial set.The present situation that the present invention needs many people to coordinate while combining the front Inspection of Thickness of floor concrete initial set, a people can use a kind of many thickness cast-in-situ floor THICKNESS CONTROL instruments of inspection and the method for inspection THICKNESS CONTROL before the initial set of cast-in-place structural floor concrete is checked fast, before the initial set of cast-in-situ floor concrete, adjusts at any time plate thickness.The on-the-spot reinforcing bar of material source of the present invention is welded, have and make simple, easy and simple to handle, check precisely, insert to check at any time floor thin and thick, adjust thickness of slab to design thickness at any time, a people can complete Inspection of Thickness and adjustment slab thickness before the initial set of floor concrete feature.
