Portable cast-in-place concrete floor slab thickness detecting tool

Abstract

The invention discloses a portable cast-in-place concrete floor slab thickness detecting tool. The tool comprises a crutch-shaped checking rod, a spring, a circular disc and a latch. The spring sleeves the lower section of the crutch-shaped checking rod and the top of the spring is fixed to the crutch-shaped checking rod by a buckle. A plurality of pin holes are formed in the lower section of thecrutch-shaped checking rod at intervals; the latch is arranged at any pin hole of the lower section of the crutch-shaped checking rod; the circular disc sleeves the lower section of the crutch-shapedchecking rod and is arranged at the top surface of the pin; and the bottom of the spring is abutted against the top surface of the circular disc. According to the tool, defects of the traditional cast-in-place concrete floor slab thickness detection are overcome. The tool is operated flexibly and conveniently; the accuracy is high; the thickness control is realized; and the pouring quality of thecast-in-place concrete project can be controlled.

Description

technical field [0001] The invention relates to a portable detection tool for the thickness of cast-in-place concrete floor slabs. Background technique [0002] Cast-in-place concrete slabs are widely used in various construction projects, and the slab thickness needs to be detected in real time during the pouring process to ensure the pouring quality of the concrete slab. At present, the commonly used detection methods generally adopt the following three methods: [0003] 1. Make concrete blocks (high-strength mortar blocks) with the same thickness as the concrete floor slab, which is equivalent to the function of ash cake during plastering, and detect the thickness of the concrete floor slab by the elevation of the concrete block; [0004] 2. Checking by inserting a sign, generally by drawing a scale on the steel bar to check the thickness of the plate; [0005] 3. Pull up the 50cm elevation control line (pile), and check the elevation of the slab surface through the con...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned methods all have certain disadvantages. The concrete blocks need to use PVC pipe molds, and the PVC pipes are invested in a large amount during production, resulting in waste of materials; there are certain errors in the detection data, and the vibration is relatively large during concrete pouring, which may easily cause the stakes to shift and cause Error; 50cm elevation control line (pile) setting process is complicated, which affects the efficiency of construction work
